    AbstractThe rise of the industrial internet has been envisaged as a key catalyst for creating the intelligent manufacturing plant of the future through enabling open data distribution for cloud manufacturing. The context supporting these systems has been defined by Service Oriented Architectures (SOA) that facilitate data resource and computational functions as services available on a network. SOA has been at the forefront EU research over the past decade and several industrially implemented SOA technologies exist on the manufacturing floor. However it is still unclear whether SOA can meet the multi-layered requirements present within state-of-the-art manufacturing Cyber Physical Systems (CPS). The focus of this research is to identify the capability of SOA to be implemented at different execution layers present in a manufacturing CPS. The state-of-the-art for manufacturing CPS is represented by the ISA-95 standard and is correlated with different temporal analysis scales, and manufacturing computational requirements. Manufacturing computational requirements are identified through a review of open and closed loop machine control orientations, and continuous and discrete control methods. Finally the Acquire Recognise Cluster (ARC) SOA for reconfigurable manufacturing process monitoring systems is reviewed, to provide a topological view of data flow within a field level manufacturing SOA

    Incorporating a visuomotor skill task with resistance training does not increase strength gains in healthy young adults

    Resistance training causes well-documented adaptations in the nervous system and increases maximal voluntary force of healthy human skeletal muscle in the trained and also of the same muscle in untrained limb. It is also well known that practice of a visuomotor skill without a load causes neural adaptations. These findings led to the hypothesis that a combination of resistance and visuomotor training would produce accelerated and larger gains in maximal voluntary force than each method alone. The purpose of the study was to compare strength gains produced by a loaded visuomotor and a traditional resistance training program. Subjects were randomly assigned to a visuomotor or resistance training group and completed 4 sets of 6 repetitions of elbow flexion at 70-85% of maximum intensity in each of 12 sessions over 4 weeks. The visuomotor vs. the resistance group performed significantly better in the visuomotor skill task. Maximal voluntary torque increased in the trained arm similarly in the two groups but, unexpectedly, not in the untrained arm. Although there is a strong conceptual and experimental basis for the hypothesis, under the present experimental conditions a combination of a visuomotor skill with loads compared with conventional resistance training did not produce superior strength gains.  M.S

    Experience a PRISMS Plus activity that builds understanding of the energy transformations from gravitational work to heat using a few simple materials. Participants will build a device for converting mechanical energy into heat, and use temperature probes and appropriate calculations to determine the efficiency of the device. This activity builds foundational knowledge required for several of the Next Generation Physical Science Energy Standards at both the middle and high school levels

    The Impact of Burnout on Human Physiology and on Operational Performance: A Prospective Study of Soldiers Enrolled in the Combat Diver Qualification Course

    (from p. 201) If little is known about the pathophysiology of burnout, even less is known about the actual impact of burnout on military operational performance. This is due to a lack of studies focused on military performance. Whether or not soldiers may feel symptoms of burnout is one thing - whether this state actually affects how they do their job is another. Within the current environment (reduced forces, increased training rates, increased deployment rates, extended tours) we believe that military personnel may be at significant risk for the development of burnout. Further, we wondered if there was a demonstrable impact of burnout on actual military performance as well as on human physiology. The present study was part of a larger investigation designed to assess the neurobiology of stress in soldiers participating in Combat Diver Qualification Training (CDQC). The portion of the study that we present here is that dealing with the assessment of burnout, HPA axis functioning and actual performance
