An alternative to the set hypothesis for warm-up decrement (WU) is proposed which states that WU is due to the loss over rest of an activity-set consisting of proper adjustment of activation, attention to relevant sources of feedback, etc. Force estimation (Exp. 1) and arm positioning (Exp. 2 and 3) were used as criterion tasks. During an interpolated rest period, activities were introduced whi...

[Purpose] This study examined whether low-frequency group exercise improved the motor functions of community-dwelling elderly people in a rural area when combined with home exercise with self-monitoring. [Subjects] The subjects were community-dwelling elderly people in a rural area of Japan. [Methods] One group (n = 50) performed group exercise combined with home exercise with self-monitoring. ...

Introduction The NCP1219 is the newest part in the NCP12XX family of current−mode flyback controllers. The controller features dynamic self supply (DSS), eliminating the need for external startup circuitry, contributing to a cost effective, low parts count flyback controller design. The NCP1219 also includes a user programmable skip cycle threshold, reducing power dissipation at light loads and...

This paper presents a study of interval analysis for solving cold-standby system reliability optimization problems with considering parameter uncertainty. Most works reported in existing literature have been based on the assumption that the probabilistic properties and statistical parameters have a known functional form, which is usually not the case. Very often the parameters are presented in ...

PURPOSE This study was designed to examine the effects of moderate-intensity endurance exercise on cycling performance, gross efficiency, and 30-s sprint power output. METHODS Two separate experiments were conducted. After a controlled warm-up, subjects completed as much work as possible in a 5-min performance test (EXP1) or a maximal 30-s sprint test (EXP2). These initial exercise bouts were...

Liquid metals are promising heat transfer fluids since they remain liquid in a wide temperature range and can efficiently due to their high thermal conductivity. A first-of-its-kind lab-scale energy storage system with filler material lead-bismuth as fluid is currently tested at the Karlsruhe Institute of Technology, while 100-kWh under construction. This numerical study aims analyse influence ...

Scaling and power reduction trends in future technologies will cause subthreshold leakage currents to become an increasingly large component of total power dissipation. As a result, new techniques are needed in order to provide high performance and low power circuit operation. This dissertation develops new circuit techniques that exploit dual threshold voltages and body biasing in order to red...

The concerned paper illustrates the comparison of two stochastic models of a cable manufacturing plant with varying demand. Here, it shows the comparison between a single unit system (Model 1) and a two-unit cold standby system (Model 2). In Model 1, the system is either in working state on some demand or put to shut down mode on no demand. In Model 2, at initial stage, one of the units is oper...

Most previous low-power personal computer designs have been either focused on power efficiency improvement or on software power management in the working states. This research aims to reduce the total standby power amount in the off state. The authors accomplish the goal of reducing the power consumption by a wake-up device which is replaced by a chip with a still lower consumption. The authors...

This paper proposes a new fuzzy assessing procedure with application in management decision making. The proposed fuzzy approach build the membership functions for system characteristics of a standby repairable system. This method is used to extract a family of conventional crisp intervals from the fuzzy repairable system for the desired system characteristics. This can be determined with a set ...
