In support of Army initiatives to meet future command, control, and communications (C3) challenges, the Combat Vehicle Command and Control (CVCC) research and development program evaluated automated C3 technology using soldier-in-the-loop simulation. The CVCC system includes a digital Positidn Navigation system, a digital Command and Control Display, the Commander's Independent Thermal Viewer, and digital workstations in the Tactical Opefations Center. The evaluation reported here compared the CVCC system with Baseline (conventional) capabilities in terms of a battalion's operational effectiveness. Using Ml tank simulators in the Mounted Warfare Test Bed at Fort Knox, Kentucky, unit commanders and executive officers with crews were integrated with semiautomated vehicles under their control to form complete tank battalions. Each battalion completed three days of training) followed by a simulated combat test scenario. One of a series, this report documents improvements in the performance of unit and vehicle commanders by key Battlefield Operating Systems, along with lessons learned. Companion reports address training issues, soldier-machine interface findings, and performance from a tactical perspective. ABSTRACT (Continued)The collective findings help determine combat doctrine, materiel requirements, and training requirements for future automated C3 systems for mounted warfare. SUBJECT TERMS (Continued)C3 2016278SA791Approved for pubic rease; distribution Is unlimited. The CVCC research program investigates advanced digital and thermal technologies to enhance mounted forces' command, control, and communications (C3) capabilities. The CVCC system integrates a variety of digital features--report preparation and management, tactical map and overlays, transmission of reports and overlays--together with positioning/navigation functions and independent thermal viewing for unit and vehicle commanders. This system provides an excellent paradigm for investigating training requirements of future automated technology for mounted combat units. The research reported here used distributed interactive simulation (DIS) to conduct a battalion-level evaluation of the CVCC capabilities.As one of three reports resulting from the evaluation, this report documents the CVCC system's impact on the operational effectiveness of an armor battalion. Companion reports address training issues, soldier-machine interface questions, and tactical performance. The findings presented in this report support Army developers in determining user requirements, specifying training requirements, and assessing operational effectiveness of auto...

Sawing frozen wood differs significantly from sawing unfrozen wood. Temperatures below zero degrees result in an increasing hardness of wood, rising cutting forces and a progression of tool wear. Currently, the adaption of process parameters due to different wood temperatures is based on operator experience, leading to overloaded saw blades, hence causing considerable economic damage by increasing production downtime. This paper presents the development of a measuring and control unit featuring an integrated database of processing values enabling operators to use most suitable process parameters, thus extending the service life of circular saw blades and increasing the performance of sawmills.
