In VANET, the researches based on the wireless LAN are conducting and the method based on 802.11a is being adapted in IEEE 802.11p WAVE (Wireless Access in Vehicular Environments). However, wireless LAN which uses a single channel in a competition can cause transmission delays because of a frequent collision and a use of CSMA/CA(Carrier Sense Multiple Access/Collision Avoidance) VANET(Vehicle Ad hoc Network) requiring a fast access. In this paper, we designed Clustering-based Multi-channel MAC(Media Access Control) protocol adequate to VANET and then confirmed the appropriate channel conditions in a V2V(Vehicle to Vehicle) communication on the basis of this protocol. The simulation results showed that a packet collision and a transmission delay by the use of an existing single channel based on the contention decreased more than 60% by making cluster head assign and manage each channel.

As a key component of personal computer, CRT monitor is the major source of compromising emanation. In this paper we design an emission-security standard which determines the allowable range of unwanted radiation emission from an electronic equipment to prevent eavesdropping of information. We assume a model for radiated emission from CRT and the results show that these emissions are approximately 25 decibel upper than proposed standard in VHF/UHF band. Nevertheless they are acceptable in published EMC standards.

Automatic building extraction is a bottleneck of automatic surveying and mapping of big scale urban image. For the single aerial gray-scale image, the automatic buildings extraction, an algorithm based on the principle of confrontation and using the priori knowledge of building is presented here. A two-dimension OTSU segmentation will be used to do the rough segmentation because of the characteristics of high-brightness which the roof of the building has; then we use mathematical morphology, image segmentation, edge detection and other measures to detect the non-building, so using the principle of confrontation and removing the non-buildings, the buildings can be extracted. At last the extraction result will be verified using the information of the building shadow, the area of building roof, altitude information and other prior knowledge, in order to improve the accuracy of building extraction in the aerial image. Moreover, the method proposed is test in our experiment using the true-color aerial image. Theoretical analysis and experimental results show building can be extracted effectively by means of the algorithm proposed and it is necessary to research deeply.

The extensive dynamic capabilities of browsers allow for platforms of infinite extensibility and omni-functional power to be delivered via the internet. This paper considers the advantages of converting web pages into intelligent immersive omni–functional documents. Such standards-compliant documents can be intermingled with web structures to create powerful models for the next generation of internet usability. The paper documents the advantages of converting every webpage into a calculation platform (named CALCI Websheets) that demonstrate more power than the most advanced spreadsheet tools, and the interesting presentation possibilities associated with it. By providing multi-layered calculation elements, this medium provides powerful paradigms in the ability to calculate, to think and to present. Manipulation of complex data types in such spaces is specifically considered.

Intrusion Detection Systems (IDS) for Mobile Ad hoc NETworks (MANETs) are necessary when they are deployed in reality. In This paper, we have presented a combined method of selecting IDS agent nodes in mobile ad hoc networks. Since, the IDS agents in MANET due to more activities need to more battery power. In our method, first, compromised nodes are detected and then the nodes with the highest energy power from among valid nodes as IDS agent nodes are considered. So, with this method, some valid nodes contribute in intrusion detection activities and costs of the network monitoring will be reduced and the network lifetime will be increased.

A cheap guidance system based on AT89C52 microcontroller is developed for facilitating visually impaired people. Ultrasonic sensors are used to calculate distance of the obstacles around the blind person to guide the user towards the available path. Output is in the form of voice which the blind person can hear e.g., right, left etc. In its advance mode, the system will be able to recognize objects using image processing algorithms. Results are presented to show the validity and performance of the system.
