Hydrogen fuel cell bus for delivery to lead the Olympic model innovation

After transformation, the Workers Stadium, with a total construction area of 80,000 square meters, can accommodate 62,000 spectators, the venue facilities fully meet the technical standards for the Olympic soccer competition.

Previous page turn the tables looking at the calendar, Beijing Futian Automobile Ji-Hong Liu, deputy director of the Technology Department has a special look.

July 10, they and Tsinghua University, developed and manufactured with three hydrogen fuel cell bus will be officially delivered Organizing Committee for the upcoming 29th Olympic Games in Beijing to provide services. “Olympic Games provides us with the best display platform.” He told reporters, “For this world-class show, the past few years the company accelerated development of new energy progress of automobile technology.”

Not just for the Olympics to accelerate the development of new energy vehicles, Science and Technology Minister Wan Gang tech Olympics this year in May had the effect of the implementation of seven years to do this kind of conclusion: combination of the Beijing Olympics with the great scientific and technological requirements, development and application of a large number of advanced and innovative technologies for the results, for the Beijing Olympic construction and services provide comprehensive technical support, while also greatly promote the S & T Yi Ji Hua Industry Development.

By the “East Wind” for science and technology project management to bring enlightenment

May 17, 2007, an intruder knocked Environmental Sciences, Tsinghua University, Professor Wang Chengwen’s office.

“Which is Professor Wang Chengwen?”

“I am.” Professor Wang was surprised to see the newcomers responded softly.

“I designed the Beijing Olympic Forest Park in the Group of Experts He Weijia, is to ask to your source separation techniques.”

Three-year construction of the Beijing Olympic Forest Park is China’s largest urban ecological parks, relying on “separation of domestic waste and resource utilization of the circulatory system,” the first time realized in the international large-scale sewage “zero emissions” technology . The key technology which source separation — is He Weijia so get the.

Since 2003, oko Committee identified “demand driven” approach to project management by the owners of the Olympic project construction technology requirements, project research. Research unit from the previous “research starting from the Olympics” to “demand from the Olympics starting to do research.” This approach changes, streamline the relationship between production and research led to a large number of mature application of scientific and technological achievements transformed the field of Science and Technology Director for the Olympic Games, said.

Olympic construction of a high standard for science and technology provide a lot of room for this in the “demand driven”, so long as the owners need technology, they will take the initiative to look for scientific research units, and will cost from the market point of view, to a large number of not previously opportunity to enter the market, scientific and technological achievements, and similar products through a contest, have the opportunity to get out of the ivory tower applications.

By Orson Park “phase” before, Wang Cheng-wen has been in the country to seek applications for his research opportunities. Modern sanitary conditions of the main components of human sewage from the faeces, 80%% 50%% of nitrogen and phosphorus from urine, treatment is difficult because compliance is likely to cause eutrophication and other environmental issues. If the discharge of urine when they separated urine through the treatment system will be processed into organic fertilizer in urine, we can solve this problem. This source separation concept, first proposed last century in Europe, in the international arena is considered to locate the best and most complete eco-system approach. Germany’s national development framework has been clearly written: “By 2100 the gradual change to the existing municipal facilities, full implementation of source separation Sheng Tai health treatment methods.” But the idea has been in the promotion and technical research. Wang Cheng-wen did not expect, “Tech Olympics” ideas of the implementation of many years of research even let him have the opportunity to become a reality.

After the separation to collect, process? How to produce organic fertilizer for the garden trees grow? How to make recycled water after treatment compliance covering the park lake? Bent to let Orson Park to achieve “zero emissions” He Weijia and colleagues from the design of “demand” start looking for a step by step, integrating related technologies, ultimately form a complete circulatory system, the project was tech Olympics projects, the idea finally become a reality. At the same time, the system in various aspects related to the large number of mature technology and the results were found industrialization opportunities, and through the Olympic Games to display at home and abroad.

Like the Olympic Games, “Dongfeng” successful transformation of many scientific and technological achievements. To promote more mature technology, since 2004, oko Olympic Committee demand combined with high-tech products, organization of various special promotion will include LED and semiconductor lighting, photovoltaic power generation, food security, information communication, etc. Total over 20 times. “After 2004, we support the Olympic projects 100% demand-driven, effective in resolving the earlier Chan Xueyan out of sync problem, on the Jin Hou’s technology projects Guanligaige Ye Dailaiyixie inspiration.” Field said.

Handling of the “opportunity” to enhance the international competitiveness of related industries

Beijing University of Olympic badminton, rhythmic gymnastics competition hall, with new, lightweight long-span prestressed world’s first dome, the many unique new Olympic venues. And to steel as an expert, personally presided over the complex steel structure system innovation, optimize the design and structure health monitoring Quan process of research and application, to Beijing University Vice-Chancellor Professor Zhang Ailin He benefited from the research team.

For the “Tech Olympics” concept, since 2001, in Science and Technology, Beijing Municipal Science and Technology Commission and the State Sport General Administration have jointly launched a major scientific and technological Olympics 1209 issue, which relates to energy-efficient buildings, green environment, information communication, intelligent transportation, scientific training, security, food security. Office of Science and Technology Commission of Beijing Olympic Games, said Don Juan, these research projects and applications results in accelerated promotion, but also to upgrade the university, research institutes and enterprises the level of innovation and R & D capabilities.

Dome of this structure itself is not new in Japan and China have such structure of the building in Tianjin, but are relatively small, the largest span of less than 40 meters. Badminton Hall Beigong like such a great span of 93 meters, at home and abroad had never been. “This is a very big difference between the degree of difficulty. Like a kind of ceramic art in very thin plates, compared with a 5 inch diameter, thin plates, making a 10-inch thin plates increase of complexity, no simple linear growth. ”

In 2002, Zhang Ailin in National Natural Science Foundation under the sponsorship of prestressed steel structure optimization design study for the construction of the Olympic badminton hall, which became Zhexie results of application of basic research and the promotion of the catalyst, they got Beijing Municipal Science and Technology Committee Special Olympics, “Olympic badminton hall prestressed steel structure system design and optimization of structural health monitoring” support.

At that time, not in the area of prestressed steel specifications, the Olympic badminton hall and other main structure of the Olympic project and both are used in prestressed steel. Thus, leading scholars Zhang Ailin Beigong steel and Professor Lu Cilin, on to the National Standardization Committee for the “Technical Specification for prestressed steel,” the preparation of the project. In recent years, along with the venues have grown up with, as well as China’s first “prestressed steel technical specification.” From 2004 to 2006, the six drafts of the regulations, published in late 2006, the number of Olympic projects prestressed steel construction and provide a basis for acceptance. Order was published, received unanimous praise, steel circles, many experts are happy to evaluate, said the results were “born” right time, to fill the gaps of the country.

At the same time, the structural engineering disciplines Beigong 2007, was named national key disciplines. The leading interdisciplinary research, closely linked with the construction of Olympic venues. Prepared first, “Prestressed Steel Technical Specification”, the Beigong structural engineering discipline is also involved in the completion of the National Stadium Model Test, “nest” part of the pile a number of experiments to work for the Olympic badminton hall and so the design of Olympic venues and building solve the technology problems at the same time, enrich their own research directions and issues, gained valuable practical experience of major projects, training personnel, rapidly growing up.

“Our structural engineering discipline is the only Ph.D. in 2000 mandated that this can be said to increase in leaps and bounds. If there is no other technological innovation badminton hall, perhaps we will not progress so fast.” Zhang Ailin said with emotion.

Just completed the “2008 Olympic project and results of innovative technologies integrated steel” compilation, the State Engineering Research Center for Steel Structure Engineer Hou Zhaoxin told reporters, steel construction and reinforced concrete construction compared to light earthquake, materials can be used repeatedly to protect environment, the international construction industry development direction. Beijing Olympic venues in 37 venues, built or extended venues have adopted the main steel structure system, in which a large number of unique design innovative structural system works. The high-tech steel concentrate on building the Olympic venues, allow our steel industry greatly improve the technical level, 不仅 sustainable for future reference in many major engineering construction, but also for future residential construction in the country to promote a solid steel base .

At present, China and the “Technology Olympics” and foreign patent applications related to the quantity of more than 320, more than 180 authorized patents. Don Juan said that, in addition to steel, the “Tech Olympics” to China’s new energy vehicles, mobile communications, ecology and environmental protection industry innovation capacity rapidly.

Do “demonstration” to promote energy conservation for sustainable development

These days, the Summer Palace, Beijing, Changping District, Yuen Foong way to often see three 12 m long white buses run during the final load test. This is the Tsinghua University and Fukuda cooperative R & D, will serve the Olympics of hydrogen fuel cell vehicles.

In the international arena, Olympic Games, showcase their technologies and products for the Olympic service, imagine the excitement of Monte. Excited not only him, during the Olympic Games, a total of 500 new energy vehicles for the Olympics. Number of new energy vehicles in China R & D institutions and auto manufacturers, for the first time the opportunity to own such a large display of new energy vehicles property rights to domestic and international audiences.

Since the 70s from the 20th century, the Olympic Games to protect the environment as the third pillar of the Olympic spirit. Beijing Olympic Games also solemnly promise: to “strictly control vehicle exhaust and other pollution sources and pollutant emissions of major pollutants in urban areas the daily average concentration in the most adverse weather conditions to ensure the air quality standards required to achieve the International Olympic Committee” . New energy vehicles for its excellent energy-saving and environmental protection into all the Olympic host city Olympic propaganda theme of Green Olympics and the primary means of technology, has become the first choice for the Beijing Olympics car.

“This is the international community to honor our commitments, is a for government, business, public awareness and understanding of opportunities for new energy vehicles.” Energy and Transport Ministry of Science and Director of Wu Ping and even that since the Olympic games led the demonstration, China now The new energy vehicles “into the history of the best stage of development.” China is a responsible big country, through the Olympics, to show the Chinese people to solve environmental problems and energy to resolve. Demonstration run at the same time also has the popular features of new energy vehicles to the Chinese popular knowledge, perceptual and rational knowledge to the public from such vehicles, to accept this car, change the way people choose the future of transport.

To enable a better understanding about energy saving ideas, Science and Technology has also been invited to host Yang Lan known as the “2008 Beijing Olympic demonstration and application of new energy vehicles,” image ambassador.

In recent years, with the “Hi-tech Olympics” special of the continued support of domestic energy systems, new energy vehicles car, drive system, control system development platform for continuous improvement, at the same time, the National Development and Reform Commission in November last year launched the country’s first “The new energy vehicles production access management rules.”

“In the past, the new energy vehicles has been in a non-standard, non-management practices of the state, 我们 corporate R & D Shengchanzhineng Ziji find in Europe, the United States, Japan’s standard to do. Now Zhege rules of generator, Rang our manufacturers in the development of new energy vehicles O’clock to rule-based, walk a few detours. “LIU Ji-case evaluation of the standard,” if not the Olympics, perhaps the introduction of this criterion is not so fast. ”

Like him, many producers in developing new energy vehicles in the eyes, the Olympic speed up the social concerns of new energy vehicles.

Don Juan told reporters that in addition to new energy vehicles, there are a number of “Technology Olympics” project is committed to energy saving concepts and technologies to promote. The use of green energy, using solar, wind and other green energy for the Olympic venues to provide a total supply of about 64.5 million kWh / year, the Olympic venues to reach 26.9% of green energy supply, reduce carbon dioxide emissions 57,000 tons / year; in energy efficient technologies integrated application of energy saving, green lighting, ground source heat pump, cooling heating and power for other high technology to achieve energy saving 60-70%; in ecological improvement and environmental protection, through the extensive application of rainwater use, water reuse , sewage treatment and recycling, air pollution control, urban sewage and garbage comprehensive ecological improvement and environmental technology, for the “Green Olympics” concept provides a scientific and technological support.

At present, the Ministry is in conjunction with related departments to formulate projects to promote new energy vehicles and other new technology and its achievements in the Olympics after the end of industrial promotion and application, in the larger context of promoting China’s greenhouse gas emissions.

Lithium-ion battery electrolytes for lithium ion batteries required key material used between the battery positive and negative conduction electron, a lithium-ion batteries for high voltage, high specific energy and other advantages of the guarantee, its development depends on the lithium-ion batteries development.

The lithium-ion batteries with high voltage, energy density (light weight), the end of self-discharge rate, no memory effect, long cycle life, and without any pollution, since the market has been developing rapidly, has been gradually to replace the nickel-hydrogen batteries Er In notebook computers, mobile phones, video cameras and other mobile electronic terminal devices dominated the field, according to Yano Research Institute survey, the global mobile phones, laptops, digital cameras, lithium-ion batteries are lithium-ion batteries account for 49 total %, 36% and 4%.

For the lithium-ion battery market prospects, comprehensive Yano Economic Research Institute, the United States Frost & Sullivan, IIT, Samsung SDI, etc., after the company’s view that: 1) the future increase in demand for portable devices and recent multiple tasks can be handled with ordinary consumers, ” small parts “market expansion Du Li-ion battery market will drive growth, but the next Suizhao Brazil, Russia, India, China and other emerging markets mobile phones and notebook computers of further spread, the growth of portable products will Fanghuan; 2) Diandong Hardware | Tools Tools, and other consumer electronic products, light electric vehicles and electric vehicles and other new applications are for the lithium-ion battery into the high growth momentum for the industry and the car’s lithium-ion battery market will continue growth in the next 5-7 years . In general, lithium ion batteries in 2008 or even 2009 years ago, will maintain double-digit overall growth rate from 2010 to less than 10%, as of 2016 output lithium ion battery market is expected to challenge 10 billion dollars, lithium-ion batteries are also broad prospects for lithium-ion battery electrolytes industry enormous imagination.

For Nokia, Sony and other companies recalled mobile phones, notebook battery case, industry experts believe that lithium-ion battery is still the best, most secure choice, although many companies in the development of fuel cells to replace lithium-ion batteries, but portable fuel cells has not yet reached commercial standards, and are not 100% safe. The analyst GeoffBlaber that Zai Shi Jian Nei next De 1-2 years this situation will not change You Tai Tai, and Jishidadao commercial standard of its products in Shouji Deng Pu Jiye Xuyaoyiduan time, so Jin Nian Dian Chi in Wu Xu worried that other Product of the lithium-ion battery replacement.

Meanwhile, the lithium-ion battery production concentrated in the (mainland), Japan and South Korea, in 2006 the proportion of its total global sales were 21%, 58.1% and 16.8%, South Korea’s future with the strong development of brand electronic products and China’s strong domestic demand continued to grow, sales of Japanese manufacturers, the proportion of lithium batteries will gradually decline. As the lithium-ion battery production in the global context of the highly centralized, the industry believe that the domestic lithium-ion battery electrolytes industry in the future the development of Geng should look at the Quanqiu the development of lithium-ion battery market.

The HP Pavilion dv9000 series laptop battery features: long battery life and maximum power, quick-charging!

Customer Review

“I bought a second laptop battery as I am often at client sites and need the time 2 batteries will give me. The original battery (18 mos old) is starting to show some signs of reduced life. The backup (1 year old) still gives me 2-3 hours. I make it a point to unplug my machine and cycle the batteries a couple of time a week. There is no faster way to kill a battery than to leave it plugged “for 99.5% of the time” as some of the reviewers admit doing. I learned that lesson on previous machines. There’s nothing wrong with either of pavilion DV6000 battery I have – I am very satisfied. I think the problem with the other reviews is user error. BTW – you should expect to replace the battery every 18 months – shorter if you abuse it by leaving it plugged in. I’ve been using laptops exclusively since 1995 and I have never had a battery that didn’t completely die within 2 years. That’s just how they work. Cycle the battery all the way to 0 at least once a week. That will give you the maximum life from it. These are no worse than any other battery.”

“I have had my dv9000 laptop for 2 years, this past December. So that is roughly 26 months now and I leave my laptop battery in my computer ALL the time and it still runs. It all depends on what power setting I am using. On high performance, the battery will still last about 45 min to an hour and on power saver it will last roughly 2-2 1/2 hours. I try to take care of my computer, but it has over heated on numerous occasions (all my fault for not using a cooling pad) and the battery is still going. (Wish HP had better design to cool the laptops) To bad the replacement batteries are so expensive.”

“My business partner bought the Pavillion DV9000 battery as more useful office computers for the company in 2004. The HP laptops have been wonderful. The first battery that came with the laptop lasted about two years. The second about 18 months. The third barely made it through a year. I have had to park the laptop because it is eating up our media budget. The other laptop does not use batteries as quickly, but it is not used as often. No, the laptop does not stay plugged in all the time. It stays in its case, battery in a separate compartment. I was told that is the best way to store the laptop. So today, I am finally ordering battery number 4. At these battery replacement prices, we may have to go back to another brand, which I liked much less. What a shame.”

“Both the original battery and a replacement spare battery only lasted about 1 year before reduced run time made them only useful for moving from one AC outlet to another. I’m ordering another with hopes that the battery has been improved. I think my mistake has been to leave the battery in the computer and on AC most of the time. HP should have software on the computer to prevent destruction of the battery due to overcharging.”

Hopes that help you. Via laptop battery blog

Each PC requires open ports for Internet, Mail and Messenger. For ports, the input and output ports of your computer and Hp pavilion zv5000 battery, any Internet-related applications are an open port required. But open ports are potential gateways for attackers. Moreover, important for the in-depth understanding of firewalls knowledge of ports.

The lion’s share of Internet communication is done via the TCP and UDP protocols, so for example, the Internet traffic that is going on in your browser or mail program. Any application that is connected to the Internet in connection point to the TCP and UDP port number. So “” knows every data packet, to which application it belongs, so to speak, the port is the address for a particular type of Internet data. A HTTP packet for the browser ends up not in the mail program and a package of mail found its way into your mail client and not end up in the browser, thanks to each packet reaches its correct destination port numbers.

Sockets are the addresses of PCs and servers

Completing the address of a data packet with the IP address of the target Rechnerns. The combination of IP address of the target host and port number of the target application on the target machine is called a socket. Two sockets define a connection, one for the output and one for the target computer and Hp pavilion dv2000 battery. Thanks to the socket of each data Pact lands on the correct computer in the correct application. Conversely, there are of course on the server that makes the data available, the sockets, that is: There, too, have the appropriate ports open. Which brings us back to the subject would be.

Responsible for incoming mail POP3 server is working for example on port 110, a web server listening on port 80 (if you run even a web server on your computer, you have this when commissioning a port. Default is 80, is there an other its port (because you run two web servers simultaneously, for example), you must explicitly specify the way such as Apache’s configuration file).

Each data packet therefore knows which port it is addressed. For this he is in fact added to the header of the data segment the sender and the destination port number. This applies to both the TCP and UDP for the protocol.

Server processes are always static port numbers, client requests get assigned to every request against a dynamic port number. A unique socket for a request to a web server (as are the open source Apache or Internet Information Services IIS from Microsoft) with the IP address 192.168.1.18 might look as follows: 192.168.1.18:80. And if the requesting client computer’s IP address 192.168.100.12 has, then the socket for the supplied site would look like this: 192.168.100.12:49152 – whereby the latter would be the dynamically allocated port for the answer.

Route change : Routing tables and print

Routing refers to the forwarding of data packets from a network (LAN , Internet) to another. The router has this so-called routing tables.

Route Print

With route and the appropriate options or commands, change the routing table of your computer and Sony vgp-bps9/b battery. For example you can set a new gateway : route change. Or print out the existing route : route print, the result is also the result of the command netstat -r. add together with a number of options you add a new route. With route / s , show all options.

These routing tables are typically created dynamically , either through the OSPF or RIP protocol. Routers on the way, additional commands to route management, for example, show ip route.

Nslookup

With the help of the DNS protocol (Domain Name System ) can be connected easily to man -to-remember host name with an IP address. With nslookup , you can manually send a request to a name server to resolve a host name. You can also find your name servers with nslookup and identify problems with name resolution.

Nslookup provides all the information to the DNS server of your computer and Sony vgp-bps9/s battery. Enter a host name when you start nslookup , for example www.pcwelt.de . Nslookup it resolves to an IP address.

Hostname , FTP , Telnet

Hostname:Get the hostname of your PC.

FTP : File upload and download via File Transfer Protocol

Usually you do FTP transfers with a suitable FTP client, such as Filezilla or a file manager with integrated FTP function as Total Commander. FTP uploads you make such as when you update your website , FTP downloads occur when the latest version of Firefox will pull down from the FTP server from Mozilla.org before it is officially known . But for just in case the FTP command family is also on the command line. By entering FTP ( which stands for File Transfer Protocol) you start an FTP session to Quit to exit this again. Read the help information before you start an FTP session.

By the way: Just like the classic FTP is also the command Telnet available. With it you can connect from a Telnet client with a Telnet server. Please note for both commands , however, that the Data is not encrypted and therefore passwords and login data will be transmitted in plain text.

Myth 4 An active firewall log must constantly attacks

Many firewalls report by pop -up when they discard packets that arrive without having been previously requested by a program. The pop – ups appear as a warning , sometimes even tone.But these warnings are almost always superfluous : In most cases , the reported packages only the answers to questions which have one of your tools – generated about the browser – which , however, are unaware of the firewall .

Anyone who dials also new to an online connection , you get an IP address that was eventually awarded recently to a different PC,Dell inspiron 2650 battery and sent to the remaining packages.

Also: Hackers scan the Internet for vulnerable computers running automated . Check per ping, which allow incoming connections computer by scanning all the IP address ranges. Just go to some worms. Even such scans loose in a mitteilungsfreudigen a firewall warning .

Consequence: Turn off the news – usually the firewall offers this option.

Myth 5 Closed ports enhance security

Basically mean fewer open ports less attack surface. But there is a method that can be closed ports deal : In the so -called tunnels sends the user via an open port dienstfremde data that are not intended for transmission via this port. In order to trick the network service of the port , the user data previously converted in the format .

One example: Almost always , the port 80 is open to the HTTP protocol. On such a HTTP tunnel can be exchanged and FTP data , although the FTP port 21 ( ) is closed. The FTP data were embedded it in an HTTP protocol. Especially popular for tunneling connections over HTTPS ( Hypertext Transfer Protocol Secure ) are . The integrated encryption prevents evaluate the firewall sent the data and can eventually block . Many file-sharing programs , which are used to music, movies and other files exchanged over the Internet tunnel , the data on port 80, as their default port is blocked in many companies.

However, must be configured for a tunnel , both sides of the connection. Is active on a PC no tunnel software, an attacker can not use from outside the gap.

Consequence: With the firewall to make the ports close makes sense in any case. More important is that you are not doing any online programs – such as an FTP server – you do not need. But the tools you need , you should always provide you with updates.
