Force Analysis of Bench Press on Stable and Unstable Base

Abstract

The contribution reviews current technologies for the measurement of performance in athletes during stationary exercise and validates the technology utilizing accelerometry. The behaviours of force during the bench press exercise on a stable and unstable base are reviewed and the results are presented. It was found that, training on an unstable base can be exploited by athletes to maximize their performance.

Experimental Investigation of a Centrifugal Pump Hydraulic Performance in Hydraulic Transmission of Solids

reduce the variance of the results so that they are less dependent on the specifics of a single classifier. This will also reduce the variance of the bias, because a combination of multiple classifiers may lead to a more expressive concept class than a single classifier [ 1 ]. In a clear contrast to the general performance of centrifugal slurry pumps in conventional solid–liquid systems, the total head height increased with an increase in the slurry solid mass content because of several reasons, including unique friction loss behavior ( i.e ., drag reducing feature) of

Thermal Characteristics of High Temperature Naturally Circulating Helium Cooling Loop

Abstract

The paper deals with the process properties in terms of the heat transfer, i.e. the thermal performance of the thermal-process units within a helium loop intended for the testing of the decay heat removal (DHR) from the model of the gas-cooled fast reactor (GFR). The system is characterised by a natural circulation of helium, as a coolant, and assume the steady operating conditions of the circulation. The helium loop consists of four main components: the model of the gas-cooled fast reactor, the model of the heat exchanger for the decay heat removal, hot piping branch and cold piping branch. Using the thermal calculations, the thermal performance of the heat exchanger model and the thermal performance of the gas-cooled fast reactor model are determined. The calculations have been done for several defined operating conditions which correspond to the different helium flow rates within the system.
