According to the feature of transient fault, the author proposes for the first time the automatic determination technology of the threshold by us e of the adaptive filter characteristic of wavelet transform. Based on profound researches on steady fault feature, this dissertation makes an effective token o f steady fault feature by using wavelet energy method, and proposes the new idea to identify cut-in case and cut-out case, thereby successfully gives an uniqu e description quantitatively on the characterization of the variation of fault a nd cutting condition in the monitoring system.展开更多

The study will also compare other research conducted by various organizations. In order to determine the hydroelectric energy potential, the SIMAHPP 4 (Simulate and Assess the Feasibility of Hydropower Projects) professional software has been utilized. It has been observed that the calculated hydroelectric potential conforms to energy potential calculated by other organizations such as DSI (State Hydraulic Works). Especially the turbine power, installed power, turbine design flow rate and annual energy production values in the studies have been realized with close values to the real ones. The power plant which is planned to have an average of natural streams of the past 43 years has been designed with an annual power production capacity of 210.87 GWh/year (without regulation ratio) and with installed power of 48,144 MW along with a design flow rate of 35 m<sub>3</sub>/s. As a result, since these water structures have high costs associated with them and also since they will have to be functional for many years, it will be beneficial to use various different computational methods.展开更多
It was in the 1980s that research on somatostatin(SST)in Alzheimer’s disease(AD)truly gained traction,demonstrating consistent colocalization with amyloid-β(Aβ),along with massive SST/SST cell losses(Almeida,2024)....It was in the 1980s that research on somatostatin(SST)in Alzheimer’s disease(AD)truly gained traction,demonstrating consistent colocalization with amyloid-β(Aβ),along with massive SST/SST cell losses(Almeida,2024).Although the field already had some grasp over the neuroendocrine and hypothalamic functions of the peptide,very little was known about the GABAergic interneurons(SST-INs)that synthesize it in cortical/hippocampal regions.Quite excitingly,over 40 years later,research has grown effervescent.展开更多
