Nearly permanent availability at almost all places in adequate quantity gives it a general value. This justifies considerable technical expense. Nevertheless, this complex energy system is vulnerable if an attack occurs in the area of high voltage distribution. Where energy is transferred across large distances in concentrated form, damage is relatively easy to cause. Damage leads to risk for people and enormous cost for repair of wiring and falling of use. Most attacks on high tension poles are performed by terrorists. The most frequently used tool is the saw. This method of attack is very slow and labor-intensive but easy to perform. Often the attack cannot be finished, when such terrorists have to leave the scene. Then the next storm could tilt the pole. If such forms of attack can be detected, quick engagement can help avoid bigger damage. Other methods of destroying a pole are faster, but require more effort to prepare and adequate tools. Such are welding, grinding and blasting. In such cases, the pole could be destroyed, but there is always a good chance to catch the violent person if a security system is in place. Therefore security choices for high tension poles are of great interest. This paper reports on first investigations of different sensors of this purpose.","PeriodicalId":288105,"journal":{"name":"Proceedings.

The types stressed in the paper are the high-altitude electromagnetic pulse, high-power microwaves, and lasers. Topics include generation mechanisms, interactions with security system components and possible effects, and illustrative counter measures. This paper is not intended to imply that the types of threats discussed are applicable to all types of security systems and that all systems should be designed to withstand them. For example, they would not be applicable to a residential burglar alarm. The threats in this paper might be available to a Government activity or to a well financed terrorist or sabotage organization, and are applicable to systems designed to protect against such groups. Also, although in some instances they might be used to assist in covert penetration, in most instances it is not expected that they would be used for that purpose. These threats will have the capability to render the total system or major components thereof inoperative, and this is the manner in which it is expected that they would be encountered.","PeriodicalId":288105,"journal":{"name":"Proceedings.

Repels: a new rapid deployment guided radar sensor 斥力:一种新的快速部署制导雷达传感器

Thus, in less than 20 minutes, a person can set up a sensor that establishes a 100-metre long detection barrier (several metres high) about a resource. Like buried line guided radar sensors it provides a terrain-following detection zone and, by operating at VHF frequencies, it also inherently optimizes detection of humans but discriminates against small nuisance targets. This paper addresses some of the physics behind the CWD technology on which the sensor is based, and contrasts this development with other sensor alternatives, including leaky cable sensors. Also discussed is the hardware design of the sensor, including both the electronics and sensor elements. Finally, the paper discusses deployment aspects of the sensor and initial test results for various intrusion scenarios. Typical applications are security for mobile resources such as aircraft and vehicles, dignitary (VIP) security, or temporary stand-in where other sensor zones have failed. Included in the test results is the sensor response to typical human body orientations and to small animals. The REPELS sensor provides a new alternative to allow rapid deployment secur ity for mobile resources and irregular sites.","PeriodicalId":288105,"journal":{"name":"Proceedings.

When this is necessary there are basically two different approaches taken for data entry \"direct\" encoding of the minutiae and \"tracing\" the ridges. The minutiae identified using these two methods on a test set of 49 latents were compared. The results indicate that these two methods are not just alternative ways of entering information but are radically different approaches which often lead to substantially different interpretations of the impression. The results of running searches on the two sets of minutiae using the Home Office matching algorithm do not indicate that either method is to be preferred from the point of view of accuracy. This conclusion is reinforced when the encodings are compared directly by eye with the matching impressions. Interpreting and encoding an impression viewed in isolation, by whatever method, is a fundamentally different task to the iterative process used by fingerprint experts to determining a match. There is scope for improving the matching accuracy of automatic fingerprint systems. The view is presented that a significant improvement could be achieved if algorithms are developed which are capable of iterative interpretation of the encoded or original data.","PeriodicalId":288105,"journal":{"name":"Proceedings.
