The results presented are related to the prediction of the specific grinding force components. The main problems associated with the prediction capability of empirical models developed using the design of experiment (DOE) method are given. In this study an approach suggesting the combination of DOE method and artificial neural network (ANN) is developed. The inputs of the developed ANNs were se...

Biological responses due to nutrient deprivation in the nematode Caenorhabditis elegans, including L1 diapause and autophagy during dauer formation, can be mediated through the linked DAF-2/insulin/IGF receptor and target-of-rapamycin (TOR) kinase pathways. Here we discuss how altered insulin/TOR signaling may underlie the previously reported phenotypes of worms with a null mutation in the pcm-...

Phase change materials are a promising strategy to reduce energy consumption in a wide range of applications including the building sector. Many studies have been done to evaluate the impact of PCM on thermal properties of building materials, however there exists little information on the influence of PCM on other properties of the support materials. This knowledge is necessary to determine the...

passive solar systems such as solar chimneys need solar radiation in order to work. therefore, they cannot present stable natural ventilation when solar energy vanishes: to have a more robust and stable condition, solar energy should be stored during the day and released back during the night. phase change materials can save additional thermal energy during the day and release it during the nig...

Codecs used in telephone networks in the United States have a -law companding characteristic solely designed for the purpose of transmitting voice signals [1, 2]. These -law codecs are not well suited for the latest generation of high-speed digital voiceband modems requiring PCM data transmission at the quantization levels of the codec [3, 4, 5, 6, 7, 8, 9]. In this paper, we have shown that us...

the study addresses performance control matrix (pcm) to determine service quality items of priority for improvement. most businesses focus on customer satisfaction when undertaking surveys of satisfaction and dissatisfaction, while generally neglecting employee satisfaction. therefore, this study develops an integrated model to improve service quality in taiwanese finance industry employees. a ...

Latent heat storage is one option to increase the efficiency and reduce CO2-emissions of process applications in temperature range between 100 °C 250 °C. In present study a latent system based on flown through exchanger plates according FracTherm®-design examined. The sugar alcohol d-mannitol used as PCM. A simplified capacity resistor (RC) simulation model developed. contrast common RC-models,...
