Alzheimer’s disease (AD) is a deadly cognitive condition in which people develop severe dementia symptoms. Neurologists commonly use series of physical and mental tests to diagnose AD that may not always be effective. Damage brain cells the most significant change AD. Proper analysis images assist identification crucial bio-markers for disease. Because development so intricate, traditional image processing algorithms sometimes fail perceive important bio-markers. The deep neural network...

Three-month old Polish Lowland female lambs were fed isocaloric diets containing 14.2% (standard) or 8.1% of proteins for twenty weeks. Changes in body weight characteristic normal growth performance all animals, but daily gain calculated the whole experimental period was significantly lower a low protein diet (87.9 +/- 13.5 and 158 13.8 g/day, respectively). Two series blood collections (4 hrs with 15 min interval) performed at age 21 26 weeks order to analyze hormone (GH) concentration...

Effects of infusions neuropeptide Y (NPY) into 3rd ventricle growing sheep fed on diets containing restricted (R) or elevated (E) levels protein the immunoreactive (ir) somatostatin neurones, ir somatotrophs, growth hormone (GH) concentration in blood plasma were studied. The long-term restriction diet elicited: enhancing irSS content periventricular perikarya; diminishing stores median eminence and elevating number somatotrophs irGH. NPY enhanced perikarya E diminished irGH R diet. as well...

This paper presents load flow analysis and the mathematical steady-state modeling of Static Synchronous Compensator (STATCOM) to study its effect on power system network.More precisely, we propose a new approach method so-called direct algorithm then compare it with indirect in testing cases: IEEE 5-bus, 14-bus, 30-bus systems.We accuracy, number iterations computational time.The simulation results show that is effective terms speed computation various practical applications.

Abstract Hardwood species are becoming increasingly important with the growing need for a diversity of forests that have recently been facing global temperature changes or conifer pests. This further leads to growth its potential as building material may originate from sustainable production. As hardwoods be properly processed, article deals disintegration European beech. The influence wood grain direction, uncut chip thickness and cutting speed on force magnitudes was experimentally...

In the power company CEZ in North Moravia Region (the Czech Republic) monitoring of a number selected parameters quality electrical energy (harmonics, flicker and unbalance) is being carried out cooperation with research laboratories Faculty Electrical Engineering Computer Science, VSB - Technical University Ostrava. The complex manner 59 feeding points 400 V, always within one week intervals, at same time on all voltage levels (HV, MV LV). whole cycle lasted for 3 years, currently fourth...

Standard EN 50160 ED. 3 was released in 2011 and despite the fact that this is third edition of standard, it still does not limit values for all parameters at voltage levels. This article examines various methods evaluation variables with two levels then presents some recommendations amendments undefined vvn network 3rd.

The energy independence, reliability and safety of distribution system operation as well use renewable resources have been hot research topics in recent years. This leads to the development active grids with specific requirements. Power Quality problems can arise when using sources grids. Problems are caused by decreased short-circuit power local sources, stochastic supply electric from operating grid off-grid regime without connection external system. In case these conditions, mutual...

The complex manner 59 feeding points 400 V, always within one week intervals, at same time on all voltage levels (HV, MV LV). paper, results during 12 years will be summarized...

High-quality supply of electricity is one the most important part transmission to customers. For distribution companies are responsible face any complaints about quality electrical energy. All such must examine and then determine what type claim it is. Verifying legitimacy claims power monitoring carried out parameters according ČSN EN 50160th. justification complaint on take measures that would remove cause quality.

In the power company ČEZ in North Moravia region monitoring of a number selected parameters quality electrical energy (harmonics, flicker and unbalance) is being done cooperation with research laboratories Faculty Electrical Engineering Computer Science, VŠB - Technical University Ostrava. The complex way 59 feeding points 400 V, always one week intervals, at same time on all voltage levels (HV, MV LV). whole cycle lasted for 3 years, currently fourth realized. full cycles enables comparing...

This study describes the impact of operation big customers on voltage quality (VQ) parameters in medium-voltage (MV) distribution grids. The survey is based evaluation 45 VQ measurements which were carried out 15 different delivery points other customers. These made years 2014, 2015 and 2016 (15 a year) evaluated according to standard EN 50160. variations was analysed.

In 1997 cooperation began between the Faculty of Electrical Engineering and Computer Science power company CEZ on a joint project that involved monitoring selected voltage quality parameters. Over course several years measurements were carried out at 59 points distribution system low (LV) level their supply nodes medium (MV) high (HV) levels, which constituted more than 100 measured points. The continued until 2012 (with one-year break in 2009) with total scope five cycles three-year...

This paper focuses on the pivotal role of Harmonic Filters (HFs) in mitigating harmonic distortion within electrical systems to enhance power quality and efficiency. distortion, characterized by deviations from ideal sinusoidal waveform power, can cause equipment malfunctions, overheating, a reduced lifespan infrastructure. HFs, known for their cost-effectiveness simplicity, employ inductors, capacitors, resistors selectively reduce specific frequencies, thereby improving system reliability...

Electric power is the electrical appliances basic means for their functionality. In case that energy customer causes problems arise thereby complaints quality. areas with frequent of quality measurements were made in order to resolve reported and also investigate cause exceeding compatibility level

This article briefly summarizes the issue of photovoltaic panels from point their failure rate and occurrence degradation processes. The individual chapters outline methods diagnostics panel defects possible solutions.
