Kent içinde meydana gelen saldırılarda, kentsel dokunun vazgeçilmez unsurları olan yapılar ve yapıların çevreleri ciddi zararlar almışlardır. Hasarın yayılmasını önlemek ve hasar alacak çevrenin en kısa sürede eski haline getirmek için, bomba riskini göz önüne alan tasarımlar gerçekleştirmelidir. Bu çalışmada yapılar üzerinde oluşan hasarın, patlamanın hangi tür özelliklerine bağlı olduğu belirlenmiştir. Daha sonra farklı ülkelerin standartları ve uzman görüşlerini de içeren literatür taraması ışığında özellikle araç bomba saldırılarda kent ve yapı ilişkisi bağlamında alınabilecek önlemler belirlenmiştir. Bu önlemler Çok Kriterli Karar Verme (ÇKKV) metodolojisinden Analitik Hiyerarşi Prosesi (AHP) yönteminden yararlanılarak konunun uzmanları tarafından değerlendirilmiştir. Değerlendirmeler sonucunda kent içindeki bu saldırılarda en önemli kriter Kamu Yollarına Mesafe, en az öneme sahip kriterin ise Diğer Riskli Yapılara Erişim kriteri olduğu sonucuna ulaşılmıştır. Kriter ağırlıkları bulunduktan sonra bu kriterler gözleme dayalı tespit yöntemi ile iki tren istasyonu numunesi üzerinde uygulanmıştır. Sonuç olarak, kent içindeki bombalı saldırılara karşı yapı ve çevresi kapsamında öneriler sunan bu çalışma, bilinçli toplum ve güvenli kentleşmenin temellerinin atılmasına yönelik önem teşkil emektedir.

Contemporary Mexican cartel use of car bombs began in mid-July 2010 and has since escalated. Given the proximity to the United States, some literally within miles of the border, the car bombings, with about 20 incidents identified over the last 2 1/2 years, should be of interest to local, state, and federal U.S. law enforcement, the U.S. Army, and other governmental institutions which are providing increasing support to Mexican federal agencies. An historical overview and analysis of cartel car bomb use in Mexico provides context, insights, and lessons learned stemming from the Medellin and Cali cartel car bombing campaigns. In order to generate insights into future cartel car bombings in Mexico, the identification of such potentials offers a glimpse into cartel "enemy intent," a possible form of actionable strategic intelligence. For Mexico, steady and both slowly and quickly increasing car bomb use trajectories may exist. The prognosis for decreasing car bomb deployment appears unlikely. If cartel car bombs were to be deployed on U.S. soil or against U.S. personnel and facilities in Mexico, such as our consulates, we could expect that a pattern of indications and warnings (I&W) would be evident prior to such an attack(s). In that case, I&W would be drawn from precursor events such as grenade and improvised explosive device (IED) attacks (or attempted attacks) on our personnel and facilities and on evolving cartel car bomb deployment patterns in Mexico. The authors conclude with initial recommendations for U.S. Army and defense community support to the military and the federal, state, and local police agencies of the Mexican state, and the various U.S. federal, state, and local police agencies operating near the U.S.-Mexican border. The extent of support in intelligence, organization, training, and equipment is highlighted, as well as the extent that these forms of support should be implemented to counter cartel vehicle-borne IEDs and overall cartel threats ; "August 2013." ; Includes bibliographical references (pages 40-53) ; Car bombings and lessons learned in Colombia -- Early car bombings in Mexico -- Recent indications and warnings for resumed car bomb use in Mexico -- Contemporary car bombings in Mexico -- Analysis and future car bombing potentials in Mexico and the United States -- Conclusions and recommendations ; Contemporary Mexican cartel use of car bombs began in mid-July 2010 and has since escalated.

This research introduces SLIVer, a Simulation-based Logic Bomb Identification/Verification methodology, for finding logic bombs hidden within Unmanned Aerial Vehicle (UAV) autopilot code without having access to the device source code. Effectiveness is demonstrated by executing a series of test missions within a high-fidelity software-in-the-loop (SITL) simulator. In the event that a logic bomb is not detected, this methodology defines safe operating areas for UAVs to ensure to a high degree of confidence the UAV operates normally on the defined flight plan. SLIVer uses preplanned flight paths as the baseline input space, greatly reducing the input space that must be searched to have confidence that the UAV will not encounter a logic bomb trigger condition during its mission. This research discusses the process for creating a logic bomb in the ArduPilot autopilot software, creating test flight profiles, UAV log file parsing, and the analysis of the methodology. SLIVer can accommodate multiple flight profiles and parses through the corresponding log files to create a safety corridor through which the UAV is able to safely traverse through with a desired level of confidence. By utilizing SLIVer, UAV operators and planners alike are afforded increased confidence that the aircraft will operate normally throughout the duration of a mission. The proof of concept implementation shows that the input space required to validate a UAV mission is reduced by approximately 60%, a far better result than brute force input testing. As UAVs are continually called upon to fill critical civilian and military roles, it is essential that planners and users of these devices have a methodology in place to assure that logic bombs are absent from the device.

This paper is about the prototype implementation of an Unmanned Ground vehicle for landmine detection using swarm intelligence, which includes several design aspects and module implementation, requirements and metrics for hardware, experimental results and analysis, conclusions and some future experiments. Unmanned ground vehicle is a very commonly nowadays but what make this research different is we use the power of swarm intelligence to operate and decide its movements and decision. Most of the landmines are non-diffusible for example the proximity mine. This is very commonly used weapon against military tanks.in such scenario a human inspection would be bad idea. It can cause severe injury to the EOD officers or even death. Landmines are biggest treat to any military force in the world. It could even take millions of lives of innocent citizen who lives nearby the warzone. Several deaths have been reported around the world. So this is a social relevant problem that as an engineer we should solve to protect our people from these worst catastrophes.

This newly revised edition is designed to integrate information in a clear and concise for¬mat to allow law enforcement to respond to bomb threats, bomb incidents, or chemical-biological-radiologi¬cal events. The reader will find the information in this book useful as a general guide to develop local protocols to meet these occurrences. With the current threat, increased vigilance and knowledge is mandatory among all law enforcement and security officers to have a working knowledge of bombs, explosives and other threats for their own protection. Among the topics discussed include the basic techniques for risk assessment and target and hazard identification. These are essential components in relating to the probability of a bombing attack and the potential outcome of such an attack. The common methods of bomb delivery, bomb construction and methods of triggering are also demonstrated. Letter bombs, vehicle bombs and high-risk facilities such as aircraft, airports, medical facilities and schools are examined as well as the utilization of chemical, biological and radiological devices and the unique hazards associated with these devices. This book also includes a section for emergency medical service personnel in treating those injured from blast, overpressure, shrapnel and chemical agents. This text is not a replacement for trained and well-equipped bomb technicians but is designed to allow the first responder to make identification of suspect items and take appropriate action until well-equipped bomb technicians arrive on the scene.

Unmanned and Autonomous Ground Vehicle (UAGV) is a smart vehicle that capable of doing tasks without the need of human operator. The automated vehicle can work during off and on road navigation and also used in military operation such as detecting bombs, border patrol, carrying cargos, search, rescue etc reducing soldier's exposure to danger, freeing them to perform other duties. This type of vehicle mainly uses sensors to observe the environment and automatically take decisions on its own in unpredictable situation and with unknown information or pass this information to the operator who control the UAGV through various communication when it requires support. This UAGV can send visual feedbacks to the operator at the ground station. An onboard sensor gives the complete environment of the vehicle as signals to the operator.

The introduction of self-driving vehicles gives rise to a large number of ethical issues that go beyond the common, extremely narrow, focus on improbable dilemma-like scenarios. This article provides a broad overview of realistic ethical issues related to self-driving vehicles. Some of the major topics covered are as follows: Strong opinions for and against driverless cars may give rise to severe social and political conflicts. A low tolerance for accidents caused by driverless vehicles may delay the introduction of driverless systems that would substantially reduce the risks. Trade-offs will arise between safety and other requirement on the road traffic system. Over-reliance on the swift collision-avoiding reactions of self-driving vehicles can induce people to take dangerous actions, such as stepping out in front of a car, relying on its fast braking. Children travelling alone can violate safety instructions such as the use of seatbelts. Digital information about routes and destinations can be used to convey commercial and political messages to car users. If fast passage can be bought, then socio-economic segregation of road traffic may result. Terrorists and other criminals can hack into a vehicle and make it crash. They can also use self-driving vehicles for instance to carry bombs to their designed places of detonation or to wreak havoc on a country's road system.
