Effect-based weapon-target pairing assigns weapons to targets for the given desired effects on such targets. The most obvious and natural effects on targets are represented by the percentages of damage of these targets. In this paper, we focus on the generation of input for effect-based weapon-target pairing optimization. One way to generate such input is based on the Joint Munition Effectiveness Manual (JMEM). JMEM allows the evaluation of the weapons. It is a database that contains many tables, and each table contains many different data fields. Because of the sheer size of JMEM, the optimization of weapon-target pairing based on JMEM is currently focused mainly on one target at a time. In other words, the optimization of weapon-target pairing for many targets and weapons is not directly supported by JMEM, although all the necessary data is there. In this paper, we derive an input based on the given JMEM and desired effect(s), which should be useful in the follow-on effect-based weapon-target pairing optimization that is not limited to a single weapon or target. In particular, effect-based weapon-target pairing will rely on the scanning of the attack guidance table that we derive from JMEM to determine a preferred set of weapon combinations for engaging a given set of targets. © 2006 IEEE.

This paper discusses the many features and composed technologies in Firestorm™ - a Distributed Collaborative Fires and Effects software. Modern response management systems capitalize on the capabilities of a plethora of sensors and its output for situational awareness. Firestorm utilizes a unique networked lethality approach by integrating unmanned air and ground vehicles to provide target handoff and sharing of data between humans and sensors. The system employs Bayesian networks for track management of sensor data, and distributed auction algorithms for allocating targets and delivering the right effect without information overload to the Warfighter. Firestorm Networked Effects Component provides joint weapon-target pairing, attack guidance, target selection standards, and other fires and effects components. Moreover, the open and modular architecture allows for easy integration with new data sources. Versatility and adaptability of the application enable it to devise and dispense a suitable response to a wide variety of scenarios. Recently, this application was used for detecting and countering a vehicle intruder with the help of radio frequency spotter sensor, command driven cameras, remote weapon system, portable vehicle arresting barrier, and an unmanned aerial vehicle - which confirmed the presence of the intruder, as well as provided lethal/non-lethal response and battle damage assessment. The completed demonstrations have proved Firestorm's™ validity and feasibility to predict, detect, neutralize, and protect key assets and/or area against a variety of possible threats. The sensors and responding assets can be deployed with numerous configurations to cover the various terrain and environmental conditions, and can be integrated to a number of platforms. © 2011 SPIE.

A piezoelectric energy harvesting system that generates energy from the oscillation of a mass-spring and stores the energy on a capacitor is being developed for replacing batteries in some applications. Typically, this energy is stored in an electrolytic capacitor. Here, we explore a number of electrolytic- and electrochemical double layer capacitors (EDLCs, aka supercapacitors), including a graphene-array-based EDLC, for storing this energy. EDLCs are of interest because they are potentially smaller, lighter, and more reliable than conventional capacitors and batteries. One issue with using EDLCs in this application is that the piezoelectric voltage output can greatly exceed the EDLC electrolyte breakdown voltage of a single cell, and the oscillation frequency greatly exceeds the frequency response of most commercial EDLCs. We find that electrolyte breakdown is not a serious limitation with transient overvoltage, as electrolyte breakdown is kinetically limited, and further, any breakdown is self-healing. In this study, we report results from capacitors of different sizes and response times, and find that capacitors of similar size store similar quantities of energy, with faster capacitors charging more quickly. © 2013 The Electrochemical Society.

Cobalt has been the binder metal-of-choice for tungsten carbide based hard metals since their inception. Lately, there has been concern about availability, price instability and health-related effects of cobalt. A number of research groups have investigated alternates for full or partial substitution of cobalt by various metals and/or their combinations. Some of the alternate binder elements that have been investigated are nickel, iron, and to some extent chromium. Improvements in fracture toughness, wear and corrosion resistance have been realized using alternate binders. This paper will summarize some of the developments of these new binder alloy compositions. Source

There is a growing need for high-strength, lightweight materials for automotive and aerospace applications to decrease fuel consumption, enhance performance and reduce the operating cost. Magnesium alloys have low density, good specific strength and high vibration-damping capacity.However, application of magnesium alloys remains limited due to its insufficient strength, its low Young's modulus, and the rather poor creep and abrasion resistance. Particle-reinforced Magnesium metal matrix composites (MMC) can overcome some of these limitations. Starting with commercially available magnesium alloy powders, our approach comprises of: (a) milling with hard particles to produce homogeneous powders, followed by (b) hot isostatic pressing and extrusion to fabricate the composite. Influence ofdispersoid volume fraction and processing parameters on the microstructure and mechanical properties will be presented. In this paper, we will discuss the processing, structure and properties of nanometer-size boron carbide reinforced AZ91E magnesium alloys. Source
