A. Heshu Software: Will blockchain + tourism bring us a new experience?
Faced with the sudden epidemic, attractions across the country have stopped operations. The tourism industry was shrouded in a cold winter and became an isolated island, causing huge losses. However, with the advent of the new coronavirus vaccine, the epidemic has gradually eased, and more and more people are going out of their homes. Driven by the easing of the epidemic, the development of the tourism market has shown an upward trend in terms of demand for transportation, hotels and scenic spots. However, with the rapid recovery of the tourism industry, there are also various problems.
The current tourism model relies heavily on online travel agencies (OTAs). Travel-related products and services are booked through OTAs. On the one hand, it is developing in the direction of experiential tourism, which emphasizes the innovation of tourism products. and customer experience. However, the OTA model severely squeezes upstream service providers, resulting in a decline in the quality of travel services provided by suppliers. At the same time, OTA is also an intermediary platform, and service providers and tourists will charge an intermediary service fee of RMB 77,888. For example, forcing customers to buy insurance on the platform and charging ticket change fees higher than the price of the ticket itself have harmed customers.
Blockchain technology is a decentralized technology, and intermediaries will be outlawed. The direction of the combination of tourism and blockchain mainly focuses on the high-quality development of tourism, aiming to solve the basic problems and "pain points" of industry development, identify accurate application scenarios, and gradually open up development space. "Blockchain + Tourism" provides a tourism data sharing model, that is, the shared data does not belong to a single node, but is shared by all nodes on the chain; the more valuable the contributed data, the more access to other data you have. Permissions; all nodes reasonably allocate and use data according to smart contracts.
Under the "blockchain + tourism" model, tourism service providers can directly connect with tourists. Tourists can check attractions and book tickets online through the tourism platform based on blockchain technology. Through the decentralization of the blockchain and the characteristics of information that cannot be tampered with, copied multiple times, and open and transparent, the authenticity and reliability of the scenic spots and ticket information in the blockchain platform are guaranteed, and there is no need to pay intermediary fees. At the same time, travel suppliers can use blockchain smart contracts in the consumer ecosystem to operate cross-border payments flexibly, safely and efficiently at zero cost. Inconveniences such as agency fees and remittance fees from travel service providers will also become a thing of the past.
Heshu Software uses blockchain to integrate scenic spot services, scenic spot management, new cultural and tourism consumption and other scenarios that are closely related to residents and enterprises to solve problems such as uneven service quality and consumer disputes in the tourism industry. The blockchain tourism scenario revitalizes cultural tourism industry resources, accelerates the circulation of cultural tourism assets, and ensures communication between resource service providers and tourists.All dialogue information becomes transparent, credible, and traceable in the form of a contract, thereby achieving the purpose of being non-tamperable, restraining bad behavior, and fully protecting the interests of all parties.
B. What does SCS mean? Detailed introduction to SCS Smart City Chain
What is SCS? SCS means Smart City Chain, and SCS is the English abbreviation of Smart City Chain. If you are in the Internet of Things industry, you should have heard of the term smart city industry, and SCS is related to this. Let’s introduce the SCS smart city chain.
SCS Smart City Chain is a blockchain operating system vertically applied to smart cities. Its full English name is: Smart City System. 101 urban nodes have been set up across the entire network, providing a series of comprehensive blockchain services including data storage, brain-computer data on-chain, and Token smart city exchange systems, to build a large-scale smart city collaboration system with you.
In November 2008, at the Council on Foreign Relations held in New York, IBM proposed the concept of "Smart Planet", which triggered an upsurge in the construction of smart cities. This project takes an industry application of smart city as the entry point, and ultimately hopes to use blockchain technology as the basis to open up the entire smart city ecological application. The project is specially named "SmartCity System" ("SmartCity System or SCS").
At the beginning of the new year of 2020, a sudden COVID-19 epidemic affected almost all cities across the country and became a major test for the achievements of smart city construction. So in the process of epidemic prevention and control, have smart cities played a role? As enterprises across the country begin to gradually resume work and production, the production and operation activities of enterprises gradually begin to get back on track. However, during this special period of the epidemic, how to ensure people’s travel safety?
Taking Shenzhen as an example, in order to provide good epidemic prevention and control and provide commuting services for citizens, Shenzhen Bus Group launched the "safe distance warning for epidemic prevention in carriages" based on passenger flow big data analysis, using technical means Strengthen the adjustment of bus transportation capacity. It is understood that the system tracks and analyzes the real-time passenger volume between stations in the carriage, and sets early warning standards for "safe distances for epidemic prevention in carriages" according to different models. Once the number of vehicles reaches the warning value, dispatchers will dispatch additional vehicles to reduce the gathering of passengers and improve the safety factor of bus travel during the epidemic prevention and control period.
Although smart cities have only been developed in recent years, it is certain that after the epidemic, various regions will accelerate the construction of smart cities and bring convenient services to the people’s daily necessities.
Smart City Chain is a blockchain-based smart city solution created by the SCS Management Committee (Smart City Chain Management Committee) team. Smart City Chain is based on blockchainDecentralization, high reliability, openness and transparency, clear traceability, distributed accounting, non-tamperable information, cost saving, asset circulation and other characteristics realize the value exchange of SCS digital assets. Smart City Chain is committed to solving problems such as information islands, information barriers, uncontrollable data security, inconsistent platforms, and identity trust in the construction of smart cities, and promotes the construction of interconnected, interoperable, integrated, and interactive smart cities.
Smart City Chain was born due to blockchain technology and becomes practical due to smart city applications. Smart City Chain will gradually be applied to smart city application ecosystems such as smart sanitation, smart transportation, smart finance, smart government affairs, smart security, smart medical care, smart manufacturing, smart Internet of Things, smart tourism, smart logistics, etc., forming a series of large information platforms .
1. Smart Financial Industry
Smart City Chain can realize asset digitization, and various assets, such as equity, bonds, bills, income certificates, warehouse receipts, etc. can be integrated Enter the blockchain, become a digital asset on the chain, and directly initiate transactions; it can help financial asset transactions be intelligently contracted and realize automatic execution of contracts; it can complete point-to-point real-time clearing and settlement, reduce the cost of value transfer, and shorten clearing and settlement time; it can realize safe and reliable management of digital identity information, and improve the efficiency of customer identification while ensuring customer privacy.
2. Smart medical industry
Smart City Chain uses blockchain technology to realize the storage, transfer and recovery of electronic medical records; it simplifies the medical insurance reimbursement process through smart contracts; The drug circulation supply chain is monitored throughout the entire process to ensure the safety and authenticity of drugs.
3. Smart supply chain industry
Smart city chain can realize data openness and transparency between transaction parties, forming a complete and smooth information flow in the supply chain, which facilitates traceability ; Realizing the non-tamperability of data and proving the existence of timestamps can resolve disputes between participating entities in the supply chain system and achieve easy evidence and accountability.
SCS is committed to building a smart city industry ecosystem of "system integration + open IoT platform + system operation services + big data cloud platform".
Smart City Chain is a high-quality digital resource in the field of blockchain implementation and has extremely high digital resource transaction value. Project pioneers will be the first to share the dividends of technological change. Smart City Chain closely follows the development of human social civilization and the process of urbanization. The ultimate goal is to move from shared assets, shared resources, and shared services to shared data, shared wisdom, and shared civilization. The vision of SCS Smart City Chain is: Innovate technology, change cities, promote civilization, and share wisdom!
I hope that after reading the above detailed introduction, I can learn more about SCUnderstanding S Smart City Chain is helpful; if you still have any questions, you are welcome to leave a message for interaction! With the development of science and technology, cities will only become smarter. This is a historical trend that is rolling like a river and cannot be stopped!
C. What impact will Leou’s online cultural tourism platform apply blockchain technology to the tourism industry?
Now, blockchain seems to be a myth. Everyone mentions and recommends it. In addition to the three most promising fields of blockchain - government projects, medical care, and logistics, in fact, in the tourism industry, blockchain technology also plays a huge role, and it is gradually changing Our way of traveling.
First of all, from the perspective of blockchain technology itself, the value of blockchain in the tourism industry is that the network it forms is a transparent and tamper-proof global database. Every user on the network can upload and upload information in real time. Get travel data. Once a transaction occurs, this database will quickly and accurately record the data information in the reservation and payment system, which can not only prevent overbooking, but also flexibly adjust pricing based on real-time tracking of supply and demand. In addition, after smart contracts are connected with other services such as market forecasts and travel insurance on the blockchain, tourism companies can maximize revenue.
Secondly, the emergence of travel platforms such as Leou Online Culture and Tourism has changed the way of travel for the best. The reason why websites like Ctrip and Qunar can often rip off customers is because of their high commissions. It is simply because these travel websites have monopolized the entire travel market. While bringing convenience to travel, there are naturally many incidents of cheating and robbing customers. Nowadays, the first step for blockchain to be implemented in the tourism industry is to establish a decentralized OTA platform. Decentralized institutions will re-establish the traditionally interrupted credit chain and resolve a large number of deviations from credit principles in an open and transparent blockchain. It is invisible and solves the bilateral credit problems between consumers and travel service providers.
Furthermore, let’s talk about a grand ideal of blockchain tourism, the realization of community autonomy. Simply put, tourists become the masters of the tourism industry, while big players such as Ctrip and Leou only provide order and stability. maintain. The public provides travel services, purchases travel products, and conducts travel transactions through the blockchain network, and the review and rating of tourist attractions and hotel ratings are also decided by tourists themselves. Such awesome things are not only fantasized by the entire tourism industry, but also for the public. What a good thing. Be the master wherever you go, the most advanced way to change the way you travel.
I hope it will be adopted, and friends who think it is a good write-up will pay attention
D. What are the applications of blockchain technology in commercial tourism
Big data in the tourism industry is familiar, Bundling price increases and opaque information have become the current pain points that the industry is focused on solving. When Ctrip has become a channel brand and one company is dominant, the so-called decentralization gives other companies with similar channels opportunities to decentralize the channels.
Many technology startups are currently focusing on blockchain technology because it will disrupt many industries, including banking, healthcare, education, and tourism.. In fact, in 2017, blockchain startups received approximately $1.8 billion in investment.
Blockchain in the tourism industry
I believe that everyone who travels will encounter some inconveniences to some extent, even if they have already happened in the early stage Even if you have made adequate plans and preparations, some unexpected things will still happen that will affect the entire travel experience and mood. Things like long lines at security checks, finding ID to have at the ready, and being asked to voluntarily give up your seat due to overbooking.
Secondly, there will also be the problem of fraud, which is very critical. Travel agencies lose as much as 0.44% every year, and 4% of flight bookings are rejected due to fraud. All of these problems cost the travel industry $4.8 billion annually.
Blockchain can solve these problems very well. The following are examples of blockchain applications in the tourism industry.
1. Identity Management
According to statistics, up to 40 million travel documents have been recorded as lost or stolen in recent years. However, with biometrics and blockchain, identity and travel documents can be recorded and permanently stored, accessible with a simple click. We can avoid having to print multiple documents for multiple checkpoints during travel. Credit card information can also be easily stored. Planes, hotels and passports can streamline travelers' gear, and government agencies can be more secure when handling tourists.
2. Smart Contracts
Blockchain has been used to consolidate contracts between companies, and neither party can change the terms. Within the tourism industry, there is huge room for smart contracts. Travelers and travel agencies will record all transactions in a block; loyalty programs and tourist points can be stored in the block; commission agreements between airlines, hotels and booking agents will also be very clear about who when Get paid; your corporate agreement with your travel agency can be kept forever with no questions or hidden fees.
3. Avoid fraud
As far as I know, last year about 55 million consumers made reservations on third-party platforms that they thought belonged to hotels. In fact, these websites were operated by fraudsters. operational. Not only did it cause direct losses to consumers, but it also affected the reputation of the hotel involved.
If blockchain technology is applied, it will effectively solve the above problems and help consumers verify ownership and so on. Additionally, by storing documents and identities in blocks, travel agencies do not need to manually check whether these bookings have been flagged for potential fraud. Visitor information can be securely accessed via blockchain, and losses due to fraud will be significantly reduced.
4. Overbooking
This is an old and vexing problem for travelers who may be kicked off the plane because no one is willing to give up their seats. Governments are even taking regulatory measures to punish airlines that engage in these behaviors. Through blockchain, passengers will have greater security, their bookings will be securely stored in a block, and airlines will be forced to give up excessBooking practices.
In addition, the tourism industry involves various service industries, and you will also encounter many different consumption points plans during travel. It’s just that the various points systems are complicated and isolated from each other, and customers don’t fully understand the details. This not only affects the interests of customers, but also causes trouble to travel companies. If blockchain technology is used to unify these points plans on a shared ledger and use a wallet to manage points, these long-standing problems may be solved.
E. What technologies are mainly used in smart tourism, and what systems are they specifically used in?
What technologies are mainly used in smart tourism, and what systems are they specifically used in?Smart tourism mainly uses new technologies such as cloud computing and the Internet of Things. Through the Internet/mobile Internet, with the help of portable terminal Internet devices, Hongyun Fuxing Smart Terminal is such a terminal device, which can help scenic spots effectively implement The creation of smart scenic spots.
Cloud Computing
To be precise, Cloud Computing does not refer to a specific technology or standard, but It is a concept, a computing model and an application model for IT resources. It provides ubiquitous, convenient and anytime shared configurable computing resources (such as networks, servers, storage, applications and services). Internet access required. End users do not need to understand the technical details of cloud computing or related professional knowledge. They only need to focus on what resources they need and how to obtain corresponding services through the Internet. Its purpose is to solve the massive data storage brought about by the development of the Internet. and deal with problems. The core idea of "cloud computing" is the effective allocation of computing, information and other resources. Cloud computing includes two aspects: on the one hand, it refers to the system platform used to construct applications, its status is equivalent to the operating system on a personal computer, called cloud computing platform (referred to as cloud platform); on the other hand, it describes the system platform built on Cloud computing applications on this platform (referred to as cloud applications). Cloud computing platforms can dynamically deploy, configure, reconfigure and de-deploy servers on demand; these servers can be physical or virtual. Cloud computing application refers to an application that can be expanded to be accessed through the Internet. It uses large-scale data centers and powerful servers to execute network applications and network services, allowing any user to access them through appropriate Cloud computing applications can be accessed with an Internet access device and a standard browser. Cloud computing services can be divided into three levels: Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS).
The cloud computing construction of smart tourism must include both cloud computing platform and cloud computing applications. At present, in the practice of smart tourism, the concepts of cloud computing platform and cloud computing application are often confused, such as "tourism cloud", "tourism cloud computing", "tourism cloud computing platform", etc. In fact, YunpingTaiwan has a certain degree of application independence, so the application research of cloud computing in smart tourism should focus on cloud computing applications, such as studying how to integrate and store a large amount or even massive amount of tourism information in a data center, how to build a database for tourism Various tourism applications (information inquiry, online booking, payment, etc.) that are acquired, stored, processed, exchanged, queried, analyzed, and utilized by users and tourism organizations (enterprises, public management and services, etc.). To a certain extent, cloud computing embodies the sharing and full utilization of tourism resources and social resources in smart tourism, as well as an intensive wisdom of resource optimization.
2. Internet of Things
The concept of Internet of Things (IOT) was proposed by the Massachusetts Institute of Technology in 1999. It mainly refers to relying on information sensing technologies and devices such as radio frequency identification (RFID) to connect and communicate with the network in accordance with agreed protocols, thereby forming a "network connected to things" and realizing the functional identification and identification of item information. manage. With the continuous development of information technology and applications, the connotation of the Internet of Things is also constantly expanding. At present, the Internet of Things, generally recognized by the industry and academia, refers to the use of radio frequency identification (RFID), global positioning system (GPS), and sensors, actuators and other devices to perceive and identify the physical world, and relies on communication networks for transmission and interconnection. Computing facilities and software systems are used for information processing and knowledge mining to achieve information interaction and seamless connection between people and things, and between things and things, thereby achieving real-time control, precise management and scientific decision-making of the physical world. The architecture of the Internet of Things consists of the perception layer (sensing devices, identification technology), the transmission layer (wireless communication technology, wide area network technology, gateway technology) and the application layer (cloud computing, massive data storage, data exploration and analysis, artificial intelligence )composition.
The Internet of Things in smart tourism can be understood as an expansion suite of Internet tourism applications and a form of ubiquitous Internet tourism applications. If Shanxi tourism applications based on Internet technology are called "online tourism", then tourism applications based on Internet of Things technology can be called "online and offline tourism" that cover both "online" and "offline". Internet of Things technology breaks through the "online" limitations of Internet applications, and this breakthrough is adapted to the mobile and non-online characteristics of tourists. The ubiquitous network refers to the ubiquitous network, that is, based on the needs of individuals and society, using existing and new network technologies to achieve ubiquitous on-demand information between people, people and things, and things and things. A comprehensive service network system for acquisition, transmission, storage, cognition, decision-making and use. The "online" and "offline" integration of tourism applications based on the Internet of Things reflects the "ubiquitous" essential feature of the ubiquitous network, and this essence is also adapted to the dynamic and mobile characteristics of tourists.
3. Mobile communication technology
Mobile communication is one of the things-to-thing communication modes. It mainly refers to wireless communication between mobile devices and between mobile devices and fixed devices. , to achieve real-time data of the deviceWireless connections between systems and between remote devices. Therefore, mobile communication can be understood as a thing-to-thing connection method of the Internet of Things, and is the core infrastructure supporting the smart tourism Internet of Things. The reason why mobile communication technology is specially proposed as a connection method of the Internet of Things is because with the development and popularization of mobile terminal devices and technologies such as smart phones and handheld computers (PDA), mobile communication technology has enabled the tourism application of information technology. The development from being centered on personal computers to being centered on "people" who carry mobile communication terminal devices - tourists, reflects the direction of information technology application with individual travelers as service objects. Personal computers are connected based on computer network technology, and various tourism applications are prosperous through Internet technology; while mobile communication terminal devices are connected based on mobile communication technology, and various tourism applications are prosperous through Internet and Internet of Things technologies. Mobile communication technology has developed rapidly since its birth. It has developed from the first generation to the third generation (3G) and is developing to the fourth generation (4G). Mobile communication technology in smart tourism provides tourists with a wealth of high-quality services, such as full-course (before, during, and after travel) information services, ubiquitous (any time, any place) mobile access services, and diverse users Terminals (personalization and multi-mode human-computer interaction such as voice, touch, vision, etc.) as well as smart services and smart mobile agents (intelligentagent), etc.
The application of mobile communication technology in smart tourism will greatly improve tourists’ travel experience and recreation quality, improve tourism destination management level and service quality, and make tourism management and services more sophisticated and high-quality. Advance. What mobile communication technology embodies in smart tourism is the wisdom of meeting the personalized needs of tourists and providing high-quality, high-satisfaction services.
4. Artificial Intelligence Technology
Artificial Intelligence (AI) is the basic theory, method and method that studies how to use computer software and hardware to simulate certain intelligent behaviors of human beings. Technology involves research on knowledge representation, automatic reasoning and search methods, machine learning and knowledge acquisition, knowledge processing systems, natural language understanding, computer vision, intelligent robots, automatic programming, etc. It has been widely used in robots, decision-making systems, control systems and simulation systems.
Smart tourism includes advanced computer software, hardware and communication technology with the Internet of Things and mobile communications as the core, as well as reasonable and effective allocation technology of computing and information resources with cloud computing as the core; however, , how to make full use of the large or even massive amounts of data and information that smart tourism continuously collects, stores and processes so that it can play an important role in tourism services and management is a key issue related to the success or failure of smart tourism. Artificial intelligence is the key technology used by smart tourism to effectively process and use data, information and knowledge, and use computer reasoning technology to support decision-making and solve problems. In the field of tourism research, artificial intelligence is more used in tourism demand forecastingThe role of artificial intelligence in smart tourism is not only limited to this, but also includes recreation quality evaluation, tourism service quality evaluation, tourism emergency warning, tourism impact perception research and many other fields. If the Internet of Things, cloud computing and mobile communication technologies are regarded as the architectural technologies of smart tourism, then artificial intelligence is the core technology of smart tourism.
In what industries are titanium materials specifically used?Titanium alloys are very promising for use on ships. This is related to the strength and toughness of titanium alloy, as well as its corrosion resistance. Titanium in seawater is extremely stable. Basically, it can be considered that the hull will not corrode, which can not only reduce maintenance costs, but also lighten the hull. The weight is a huge benefit to the ship. In addition, it is necessary to mention two points: First, titanium is non-magnetic, which is very helpful in resisting magnetic detection. As for magnetic mines, it is not worth worrying about. Second, it is naturally integrated with advanced ship composite material coatings. The stealth composite materials to be used in the future have a shortcoming, which is that they react with the high-strength special steel used in previous ships. Due to the potential difference, electricity is easily generated in seawater. Oops, it accelerates corrosion. This kind of thing has been tested on 052. It won't take long for it to become rusty, but these coatings can be perfectly integrated with titanium alloy.
(2) The use of titanium in the defense industry of other countries
Many of the weapons and equipment that have been retired, are in service or are under development in the world use titanium and its alloy structural parts. With the modernization The transformation of the war model requires the modern army to have outstanding rapid maneuverability. Therefore, the army must rely on the ability of transport aircraft to achieve rapid maneuverability. This requires the army's originally heavy equipment to be made as lightweight as possible. For example, all countries now hope that Your own artillery can be quickly and effectively transferred to another place to achieve strategic or tactical purposes. This will inevitably make the development of titanium alloys in the field of artillery bright. For example, the American M777 light howitzer uses a titanium alloy shell. The total combat weight has been reduced to 3.175 tons, and it can be transported by V22 or C130 by air to achieve rapid maneuverability. Similar is the British UFH ultra-light 155mm artillery, which uses 1 ton of titanium alloy in a weight of less than 4 tons. This is especially true in the field of air force and naval equipment. The following is a brief introduction to typical examples of successful applications of titanium alloys:
①Titanium data for aircraft
Nowadays, the global economy has gradually come out of the trough, and the international aviation industry has begun to With the emergence of restorative growth, the international titanium industry has also ushered in a new period of rapid growth with this trend, and Chinese companies will also usher in new opportunities.
In recent years, the replacement of fourth-generation fighter jets has begun. In the following years, many new fighter jets will enter the military every year. New fighter jets are very particular and forward-looking in material selection. In the next many years, the military and aviation industry will inevitably be the largest users of titanium materials.
Mild recently announced the design of a new type of submarine-borne "Cormorant" unmanned attack aircraft.concept. The "Cormorant" UAV has a length of 5.8 meters and a wingspan of 4.86 meters. It is an unmanned combat aircraft that can be used repeatedly. The "Cormorant" was conceptually designed by the famous Lockheed Martin Skunk Works. Because its entry and exit channels are mainly seawater, the entire aircraft is made of titanium alloy to prevent corrosion. The total take-off weight does not exceed 4 tons, can carry a payload of 453 kilograms, and is mainly used to launch from the strategic missile launcher of the Ohio-class nuclear submarine, and is mainly used to destroy near-coastal targets. The air inlet of the machine is located at the nose of the machine and is shaped like a triangle. Due to the use of titanium alloy, its body is extremely strong and can withstand the pressure of 150 feet of water depth. And in order to prevent external pressure instability, all unnecessary spaces inside the body are filled with special plastic. In order to increase the concealment of flight, its appearance also adopts a complex stealth design. The "Cormorant" is expected to have a maximum flight speed of 880 kilometers/hour, a cruising speed of 550 kilometers/hour, a maximum flight altitude of 10.7 kilometers, a combat radius of 926 kilometers, and a sustainable flight of 3 hours.
②The application of titanium in the navy
The application of titanium in the navy is also very extensive. The main application countries are Soviet/Russian submarines.
"Akula" class attack nuclear submarine: The "Akula" class adopts a water drop-shaped, double-hulled hull, with an inner layer made of titanium alloy. Designed by the famous Soviet "Malachite" submarine design bureau and manufactured by the Komsomolsk Shipyard and Severodvinsk Shipyard
"Sierra" class attack nuclear submarine: Russia's "Sierra" class (also known as S -class) multi-purpose attack nuclear submarine. It can be said to be the most mysterious member of Russia's large nuclear submarine family. Mainly because the "Sierra" class boat uses a titanium alloy double hull. Its large diving depth, high speed, strong firepower and good stealth performance are impressive. But the cost was very expensive, and it was nicknamed "Goldfish". Only 4 ships were built. (See the picture below)
As for the pinnacle of titanium materials on submarines, I still think it should be awarded the Typhoon class: the Soviet Union built a total of 6 "Typhoon" class submarines, and the "Typhoon" was the first of them ship. What's special about the "Typhoon" class is that it has a complete set of independent navigation and combat systems such as torpedoes, missiles, and power units; it adopts a double-shell structure with a reserve buoyancy of about 32%, and there is a gap of more than 3 meters between the two shells. The spacing enhances the ability to withstand underwater explosions and collisions. Each Typhoon-class ship uses about 9,000 tons of titanium, which is equivalent to my country’s current total titanium production in a year! It can be seen how huge the military investment was during the Soviet period
The Soviet Union/Russia also had titanium-hulled nuclear submarines such as the Alpha class, etc., but they have not formed a certain climate, so they will not be described again. In addition to being used on the shell, titanium on submarines is also used on the pipes and condensers of submarines. Now almost all condensers on submarines and surface ships are made of titanium. It can be said that in submarines and ships Within the service life, there is generally no need to replace the titanium condenser, which can save maintenance costs., and secondly, the attendance rate will not be reduced due to condenser failure.
Due to material prices and output, there are few reports of submarines from other countries using titanium hulls.
The performance of titanium and its alloys is unquestionable. The metallurgical processes of various titanium alloys are also very common for large countries, but they only consider the cost. With the development of the economy, the special requirements of national defense are also able to be guaranteed. Therefore, titanium and its alloys will usher in rapid development in the future civilian and military fields. At the same time, titanium and its alloys will also greatly improve the performance of some special equipment.
Are you talking about the specific business applications of multi-threading?
Think about it, if it is a single thread, and 10,000 people are now accessing a web page, and it takes 1S to execute the same request, is it only the first person who enters can access it, and the second person can access it? One has to wait 1S, the third has to wait 2S, and so on. Then everyone else needs to wait for the first person to leave before it's the next person's turn to visit. This is still in blocking queue mode. Otherwise, you may not be allowed to access directly.
If it is multi-threading, now 10,000 people visit a website, and 1,000 execution threads are opened at the same time. In blocking queue mode. Is it possible to handle simultaneous access by 1,000 people at the same time? Assuming it is all parallel, does it only take 1S for 1,000 people to see the web page, and only 10S for at most 1,000 people to see the web page?
To put it simply, a bucket is 10 liters. Is it faster if I use a 1-liter bucket to pour one liter at a time or 10 1-liter buckets at the same time?
It is used in many fields such as management, statistics and finance, and finance.
Excel is an important part of Microsoft Office suite software. It can process various data, statistical analysis and assist decision-making operations
You don’t need to know that the program execution is successful, but you need to know that the program execution failed. Success is preset.
If you really need to traverse, use vector or deque or list

HRS connectors are used in many fields, such as home appliance industry, mobile phone industry, industrial field, aerospace field, automobile and many other fields.
HRS Agent-Qiao's Electronics-Xiao Meng
It is mainly used to solve various problems in online finance, such as identity verification and transactions. Regarding bottlenecks in confirmation and fund settlement, Wang Yongli still knows a lot about Internet technology.
Interrupt technologyWhich aspect is it specifically used in computer systems?? An interrupt refers to a response of the CPU to an event that occurs in the system: the CPU suspends the program being executed, retains the scene, and automatically transfers to the corresponding processing program to process After completing the event, return to the breakpoint and continue executing the "interrupted" program
In the computers we use, all hardware needs to perform the interrupt request action. Simply put, its function is to stop other processes. The working status of related hardware. We can give an example from daily life to illustrate. Suppose you are writing a letter to a friend and the phone rings. At this time, you put down the pen in your hand to answer the phone, and then continue writing the letter after the call is over. This example shows the process of interruption and its processing: a phone call allows you to temporarily suspend your current work and deal with more urgent matters - answer the phone, and then return to the phone after finishing the urgent matters. Go back to where you were before. In this example, the phone call can be called an "interrupt request", and your pause in writing to answer the phone is called an "interrupt response", and the process of answering the phone is "interrupt processing". From this we can see that when the computer is executing the program, due to a special situation (or "event"), the system temporarily suspends the current program and switches to execute the program that handles this special event. After completion, return to the interruption point of the original program and continue execution, and this process is called interruption.
The role of interrupts
We can give another example to illustrate the role of interrupts. Suppose a friend comes to visit you, but because you don’t know when he will arrive, you can only wait at the door, so you can’t do anything; but if you install a doorbell at the door, you don’t have to wait at the door and can do other things at home. When a friend comes to work, you ring the doorbell to notify you. Only then do you interrupt your work and open the door, thus avoiding unnecessary waiting. The same goes for computers, such as printing documents. Because the CPU transmits data at a high speed and the printer is slow, if interrupt technology is not used, the CPU will often be in a waiting state, which will make the computer's work efficiency extremely low. After using the interrupt method, the CPU can perform other tasks while printing, and will only respond temporarily after the current content in the printer buffer has been printed and an interrupt request is issued. The current job is transferred to perform the operation of stopping printing, and then returns to the original program. This greatly improves the efficiency of the computer system.
irq interrupt
There are several types of interrupts in computers. According to the source of the interrupt signal, it can be divided into: hardware interrupt and software interrupt. Hardware interrupts are mostly issued by peripheral devices and computer system controllers, while software interrupts are generally generated by software commands. There are "maskable interrupts" and "unmaskable interrupts" in hardware interrupts. As the name suggests, a maskable interrupt can be decided by the computer according to the needs of the system whether to receive processing or postpone processing (i.e. masking).An unmasked interrupt is to directly activate the corresponding interrupt handler, which cannot and will not be delayed. The irq interrupt is a maskable hardware interrupt. Its full name is interrupt request, which is "interrupt request".
In a computer system, an interrupt controller 8259 or 8259a chip (now this chip is mostly integrated into other chips) controls the interrupt of each hardware in the system. There are currently 16 groups of irqs. Excluding the group of irqs used for bridging, there are actually only 15 groups of irqs available for hardware calls. These irqs have their own recommended configurations.
Assign irq interrupt
The operating systems we use daily have different irq settings, so when installing new hardware, the system often cannot automatically detect the correct irq to assign to the required Called hardware, this will cause the hardware device or the original old hardware to not work properly. In fact, this is because the system automatically assigns the irq of the hardware to other hardware with the same irq, causing a conflict and causing the hardware to not work properly. Generally, if you encounter this situation, you only need to manually adjust the irq configuration of the old and new hardware to solve the problem.
Some commonly used hardware generally has its default irq value. For example, sound cards often use irq5 or 7. Although most of these accessories can work with other irq values, if you encounter particularly "picky" software or games and other programs, such as sound cards that can only recognize irq values 5 or 7, then if you set it to irq9 It's all wasted effort.

F. Blockchain in tourism What are the application examples in the industry
1. Consumption points management
Leou online cultural tourism platform is the first in the world to cover the six major tourism fields of food, accommodation, transportation, travel, shopping and entertainment. The blockchain tourism platform transforms the company's original old points system to a certain extent, converting it into new points independently issued by the company with blockchain as the underlying technology, realizing the free trading and exchange of points, and maximizing the use of points. The services and functions help service providers achieve customer attraction and help travel consumers obtain greater benefits.
2. Air tickets and hotel bookings: Russia’s Siberian Airlines (S7) and Alfa-Bank have partnered to sell air tickets on the blockchain. One of the main advantages of using this technology is to speed up the payment process.
3. Loyalty programs for hotels and airlines
Loyyal is a universal loyalty rewards platform based on blockchain and smart contract technology, which was presented at the 2016 industry theme conference held at Burj Al Arab Hotel in Dubai Use blockchain technology to enable tourists to better obtain consumer loyalty points to promote tourismdevelop. In addition, Singapore Airlines (SIA) also announced in 2018 that it would launch a blockchain-based customer loyalty KrisFlyer program for flyers.
4. Track pilots’ professional certificates and qualifications
France’s Airbus, a participant in the Hyperledger Blockchain Alliance, is also exploring the possibility of blockchain applications. The test project is to use zone Blockchain tracks pilots’ professional certificates and qualifications, among other things.
5. Credit consumption management
On the Airbnb platform, reputation is extremely important. Users whose credit reaches a certain level can rent specific types of houses. Airbnb uses blockchain technology to better establish a reputation platform for merchants and travelers, and to effectively store identity information.
6. Digital Identity Authentication
Joanne Zen, the founder of Backpack Chain in New Zealand, is leading the team to create the BTA system, using underlying blockchain technology combined with Internet applications to create personal electronic digital identity authentication. When a user registers on the Backpack Chain APP, in addition to the regular registration process, the user's passport also needs to be scanned and facial recognition information uploaded, thus generating unique mobile personal ID information in the world. Each ID information owner will have a key, which is known only to the information owner.
7. Verify house information
Airbnb provides more than 2 million house information in 191 countries and has received 60 million customers. The P2P hotel website has achieved certain success in optimizing the one-stop process of hotel rental. It is also exploring the verification of house information, establishing a text message communication system to allow customers to communicate with landlords, and improving the payment experience.
8. Electronic identity management
In Estonia, blockchain technology has been used to develop electronic identity projects. It is reported that the country allows non-Estonian residents to apply to become e-citizens, similar to a permanent residence permit or identity card, which enables these residents to enjoy a range of services provided by the country. Currently, Estonia uses this program to encourage talented people from all over the world to start businesses in the country. Such plans would provide a significant boost to tourism in some destinations. For more information, please follow bitmom
