Mobile communications systems have evolved through wireless technology innovation into 2G, 3G, and then 4G to keep pace with ever increasing voice and data traffic. 5G, short for 5th generation mobile networking or 5th generation wireless systems is the latest…
Rare, precious and specialized metals and alloys are widely used in the defense industry, not only in weaponry and defense equipment, but also for communications equipment and infrastructure. Military contractors require metal products like nickel-aluminum bronze, Beryllium copper and copper-nickel…
Reliability, maintainability, and availability (RAM) are three system attributes that are of great interest to systems engineers, logisticians, and users. Collectively, they affect both the utility and the life-cycle costs of a product or system. Although significant improvements have…
The Department of Defense (DOD) has a well-documented history of taking much longer and spending much more than originally planned to develop and acquire its weapons systems. In particular, as systems transition from development to production, programs experience significant manufacturing…
The rapid evolution of technology and outsourced manufacturing has created new opportunities, as well as new challenges and risks. Organizations today are under increased pressure to improve product designs as well as manufacturability and sustainability while reducing costs and development schedules.…
Energetic materials and munitions are used across DoD in mission critical applications such as rockets, missiles, ammunition, and pyrotechnic devices. In these applications, energetic materials and munitions must perform as designed to ensure success in both training and combat operations. Energetic…

Mechanical-Systems (MEMS) is the integration of mechanical elements (levers, springs, deformable membranes, vibrating structures, etc.), sensors, actuators, and electronics (resistors, capacitors, inductors, etc.) on a common silicon substrate through microfabrication technology. MEMS devices are today considered as one among the…
The design of aerodynamic airfoils is optimized for certain conditions. For instance, the shape of the wings of fixed-wing aircrafts are designed and optimized for a certain flight condition (in terms of altitude, speed, aircraft weight, etc.). However, these flight…
The piezoelectric effect was discovered by brothers Pierre and Jacques Curie in 1880, and named after the Greek word piezein, that means to press or squeeze. They found that certain crystals were able to generate an electrical charge when mechanically…
