This is a classic binary match. After the grid is marked as black and white, the grid containing '*' is then divided into two groups based on black and white to create edges. The final result is the total number of '*'-the number of matches. #

This question requires a more detailed understanding of binary matching! At the same time, you need to use a little bit of brains! Unlike hdu4185, the idea of creating a graph is that 4185 does not need to cover all vertices, but this question

The basis of binary matching. You only need to find out a and B. Search for the four directions of each "*" and record their relationships; Because we read both a-> B and B-> A, we need to divide it by 2; #include#includechar str[41][11];bool mat[40

Question: In a rectangle, there are n Cities '*'. Now all N cities need to cover wireless networks. If a base station is placed, it can cover at most two adjacent cities.How many base stations can be placed to ensure that all cities are

An original Mini-game inspired by gold miners and big fish. In fact, this game has been played for two weeks and is only uploaded until now. Some bugs have not been fixed yet. No way. Busy. Recently, I am engaged in a large-scale webgame with

example. In the link budget, consider the following factors: Because of the influence of shadow fading, in order to guarantee certain coverage probability, we must reserve the shadow fading margin, take the shadow fading reserve 6dB; The fast fading reserve is the power margin reserved for power control, and the power control can resist the fast fading to some extent, Therefore, the power control needs to reserve the capacity margin. In the 802.16E network, because the terminal can move access

basic elements of label, reader and Antenna. (4) Uwb:ultra wideband, or Ultra wideband technology. UWB communication is also known as carrier-free baseband communication, almost full digital communication system, the need for RF and microwave devices are few, so can reduce the complexity of the system and reduce costs. three, wireless technology advantage and disadvantage analysis (i) WLAN technical analysis Wi-Fi technology and products have

Diversity) and Time Diversity TD, Time Diversity) technology. Multi-carrier Orthogonal Frequency Division Multi-Channel OFDM, Orthogonal OFDM) system is transmitted by multi-channel narrowband Orthogonal sub-carrier at the same time. In recent years, it has been applied in some practical scenarios and proved to have good results. The ARO mentioned earlier in this article is time diversity and has been officially used in some fixed wireless access networks. It indicates that it is beneficial to

Where are the locations of Wi-Fi when different technologies compete for the future of mobile highways? Multiple wireless technologies are competing to become the next-generation Transmission System for Mobile Video and collaborative business applications and services. WiMAX and LTELong-Term Evolution) are currently the leader in the WAN field. Qualcomm's ultra-mobile broadband UMB) technology ranks third, although it is eager to run at a speed above

, the main use of the current is optical fiber. But for the scattered, isolated areas of the single point mode, fast moving objects, the need for temporary deployment of video monitoring, the use of wired is not realistic. In this case, using a wireless network for video transmission becomes the only option. 3G products are mainly 3G cameras, 3G vehicle law enforcement system, 3G soldier law enforcement system, 3G car DVR and so on. Mainly by the operator's network to carry out video signals an

-distance video transmission, optical fiber is used currently. However, it is unrealistic to use wired cables for scattered, remote single-point mode, fast moving objects, and temporarily deployed video surveillance. In this case, using wireless networks for video transmission is the only choice. 3G products include 3G cameras, 3G on-board law enforcement systems, 3G individual law enforcement systems, 3G on-board hard drive recorders, and other applications. Video Signals and other data are tra

In today's security network of the tide, wireless technology undoubtedly plays a role in fuelling. As far as the video surveillance industry is concerned, 3G, WiFi, WiMAX three-bit as the main leading video to monitor the wireless move forward, satellite, microwave system two vanguard also in the field of emergency command and other areas, coupled with the emergence of the new generation of 4G, resulting in video surveillance wireless transmission has

, Wi-Fi, WiMax, and satellite communication networks, it mainly uses upper-layer public-discussion such as TCP/IP, gateway technology, and routing technology for image transmission. 3rd Generation. In indoor, outdoor, and driving environments, transmission speeds can be at least 2 Mbps (megabits/second), 384 kbps (kilobytes/second), and kbps respectively. At present, China Mobile, China Unicom, and China Telecom are all evolving towards 3g hsdpa. the

development, WIMAX is currently working on network structure standards and business application requirements. The standard is the creator of technical standards, and WIMAX is the promoter of technology and industrial chain. WiMAX has made an important contribution to IEEE consistency standards. With the development of 802.16 standardization,

Some key LTE technologies in Vernacular I have never been in touch with the actual LTE equipment because I am working on CDMA, but I have read a lot of theoretical materials, including the red books. I personally feel that Chinese books are not very good yet, it covers a wide range of topics, but there are very few details. If you want to study it in depth, unless you look at the agreement, but how tired the agreement looks, not like the books of previous motorcycles and Ericsson, the knowledge

Editor's note: The recent wireless market is really hilarious, 3G in full swing around the money, 802.11n obtained a legal "birth certificate", and WiMAX and WiMAX2 this pair of biological brothers seems to have a big fight in the end of 09. At the recent German ITU conference, WIMAX2 has been approved by more than 50 companies and manufacturers around the world, and has a number of companies and manufacturers to participate in

explained. However, in the final analysis, the deployment and operation costs of the network architecture must be paid. Because consumers do not need to directly bear this part of the cost, the operators of the places do not have enough enthusiasm to invest more funds to establish high-quality network services, this is especially true in scenarios where network traffic peaks rarely occur. In addition, Skinner also said that the antenna device of the

This is for the only free mini PCI-E slot models, such models are also more common, especially in some international brands of models. With the mini pci-e slot, according to the method of the previous period to add 3G network card and mobile card slots, this time only need to install 3G antenna is done. Buy Antennas as needed The price of the notebook antenna is very cheap, the general double price will n

Design and simulate Wireless LAN device antennas [Date:] Source: /21IC Author: How Siang Yap and Bart Van Hecke of Agilent EEsof EDA Department [Font: large, medium, and small] 　 By adopting polarization diversity technology, low-cost PCB substrates can be used to create Wireless LAN equipment (WLAN) antennas with good receiver performance. This article will describe how to use the latest 3D electromagnetic field (EM) simulation tool to design and simulate a 2.4 GHz orthogon

The concept of radar was formed in the early 20th century. Radar is a transliteration of radar, abbreviated as radio Detection and Ranging. It is an electronic device that uses microwave band electromagnetic waves to detect targets. Composition The specific use and structure of various radars are different, but the basic form is the same, including five basic components: the transmitter, the transmitting antenna, the receiver, the receiv
