In this paper we present several expert systems that predict the class identity of the modeled compounds, based on a preprocessed spectral database. The expert systems were built using Artificial Neural Networks (ANN) and are designed to predict if an unknown compound has the toxicological activity of amphetamines (stimulant and hallucinogen), or whether it is a nonamphetamine. In attempts to c...

The role of neurotrophic factors as endogenous survival proteins for brain neurons remains contentious. In the cerebellum, the signals controlling survival of molecular layer interneurons (MLIs) are unknown, and direct evidence for the requirement of a full complement of MLIs for normal cerebellar function and motor learning has been lacking. Here, we show that Purkinje cells (PCs), the target ...

INTRODUCTION Evaluation of effectiveness of pulmonary rehabilitation in patients with idiopathic pulmonary fibrosis (IPF) has not yet been presented in medical literature. The objective of the study is to analyze the influence of inspiratory muscle training on dyspnea (oxygen cost diagram [OCD], baseline dyspnea index [BDI]), quality of life (SF-36), results of 6 MWT (distance, dyspnea in Borg'...

Increased awareness of the impact of chlorofluorocarbons (CFCs) on the global environment has become the impetus in searching for alternative refrigerants and cooling methods for automotive air conditioning. Automotive air conditioning is one industry that heavily uses CFC compounds, and the leakage of CFCs from such air conditioners is substantial compared to that from stationary air condition...

As one of the leading international process control systems, SIMATIC PCS 7 with its functional variety, flexibility, and performance of the current version 7.1 has the potential for implementation of innovative solutions that meet the special challenges of the process industry. Since the range of available functions and the application area extend far beyond the limits of a typical process cont...

Original scientific paper Recently, there has been made a great effort to include electricity generation from the renewable energy sources into the power system. Random renewable generation creates the imbalance between electricity production and consumption, which requires power plants with fast response or energy storage systems. Generally accepted solution for load balancing is the concept o...

In this study, we analyzed the CO2 emissions of online music and video streaming services, as one digital contents, in Japan using life cycle assessment. As a system boundary streaming, processes such data center construction server manufacturing, usage communication networks internet technology devices (personal computers (PCs) smartphones), disposal centers servers were considered. Data colle...

Personal comfort systems (PCS) promise individualized thermal comfort, energy-savings and may even contribute to health by locally heating/cooling specific body segments. To date, however, insights into PCSs’ design guidelines or their effectiveness on whole-body are scarce. The fundamental question which segments should be targeted has not yet been answered. This paper attempts answer this sys...

–The objective of this work is to study the performance of a split air conditioning system with and without a Matrix Heat Exchanger (MHE) .The experiment was done using HFC134a as the refrigerant and Polyol-ester oil (POE) as the conventional lubricant in the air conditioning system. The performance of the split air conditioning system with HFC134a/POE oil system was compared with HFC134a/POE o...
