The complete lifecycle of complex systems, such as ground vehicles, consists of multiple phases including design, manufacturing, operation and sustainment (O&S) and finally disposal. For many systems, the majority of the lifecycle costs are incurred during the operation and sustainment phase, specifically in the form of uncertain maintenance costs. Testing and analysis during the design phase, including reliability and supportability analysis, can have a major influence on costs during the O&S phase. However, the cost of the analysis itself must be reconciled with the expected benefits of the reduction in uncertainty. In this paper, we quantify the value of performing the tests and analyses in the design phase by treating it as imperfect information obtained to better estimate uncertain maintenance costs. A multi-attribute decision framework for military ground vehicles acquisition is employed to illustrate the methodology and the value of performing the analysis early in the system’s lifecycle. Attributes considered are maintenance cost and operational availability, while the utility is calculated for a risk averse decision maker. Numerical methods are employed to calculate the value…

Facility Focus: Army Test and Evaluation Command

  • Magazine Article
  • TBMG-36193
Published 2020-03-01 by Tech Briefs Media Group in United States

The U.S. Army Test and Evaluation Command (ATEC) plans, integrates, and conducts experiments, developmental testing, independent operational testing, and independent evaluations and assessments to provide essential information to acquisition decision-makers and commanders.

Production Method for High-Performance Polymer

  • Magazine Article
  • TBMG-36197
Published 2020-03-01 by Tech Briefs Media Group in United States

A method was developed to produce a polymer material called PBO — known commercially as Zylon — that’s used in bulletproof vests and other high-performance fabrics. The new approach could be useful in making PBO products that resist degradation — a problem that has plagued PBO-based materials in the past.

Harness Wireless IoT Sensors for Integrated Building Management

  • Magazine Article
  • TBMG-36153
Published 2020-03-01 by Tech Briefs Media Group in United States

The Internet of Things (IoT) is proving its impact on the real estate sector. According to forecasts, building automation will lead the growth rate of connected devices in 2020. Smart building endpoints are expected to grow by 42 percent next year, reaching the staggering number of 440 million. Facility managers, real estate owners, as well as commercial and industrial businesses are looking to deploy IoT for its multifold benefits — from augmenting building efficiency and lowering costs, to improving tenants’ experience. These exciting opportunities come from granular insights into disparate aspects of building operations — all accessible from a centralized management platform.

Low-Inductance DC Power Bus

  • Magazine Article
  • TBMG-36160
Published 2020-03-01 by Tech Briefs Media Group in United States

Anew generation of power electronic conversion systems is being enabled by wide-bandgap (WBG) devices. Applications in civilian and defense sectors are already realizing improved power density and efficiency in power converters that utilize silicon carbide (SiC) and/or gallium nitride (GaN) switches; however, as semiconductor switches become capable of greater hold-off voltage, higher switching frequency, and higher junction temperature, limits on converter performance will depend on the remainder of the system: device packaging, filter components, and thermal management, as examples.

Published 2020-03-01 by Tech Briefs Media Group in United States

In an effort to make robots more effective and versatile teammates for soldiers in combat, researchers are looking to understand the value of the molecular living functionality of muscle and the fundamental mechanics that would need to be replicated in order to artificially achieve the capabilities arising from the proteins responsible for muscle contraction.

  • TBMG-35999
Published 2020-02-01 by Tech Briefs Media Group in United States

Stretchable, skin-like robots that can be rolled up and put in your pocket have been developed using a new way of embedding artificial muscles and electrical adhesion into soft materials. This new advance could create new thin and light robots for environmental monitoring and deployment in hazardous environments, robot grippers for delicate objects, and new wearable technologies.

Breathalyzer Detects Marijuana

Published 2020-02-01 by Tech Briefs Media Group in United States

As recreational marijuana legalization becomes more widespread in the U.S., so has concern about what that means for enforcing driving-under-the-influence (DUI) laws. Unlike a breathalyzer used to detect alcohol, police do not have a device that can be used in the field to determine if a driver is under the influence of marijuana.
