Objective(s): The energy resolution of a cadmium-zinc-telluride (CZT) solid-state semiconductor detector is about 5%, and is superior to the resolution of the conventional Anger type detector which is 10%. Also, the window width of the high-energy part and of the low-energy part of a photo peak window can be changed separately. In this study, we used a semiconductor detector and examined the ef...

Principal mel-spectrum components (PMSCs) [3] are computed several timescales in parallel [2]. For each timescale, the feature extraction involves four steps: discrete Fourier transform (DFT), mel-scaling, principal component analysis whitening (PCA) and temporal pooling. Firstly, for each timescale, we compute discrete Fourier transforms over a given time length. To compute PMSCs at different ...

Background: The principal objective of this study was to correlate biophysical properties vaginal discharge present in the cervical mucus with timing fertile window. In particular, we produce measures viscoelasticity secretion using two methods. first uses only elasticity extracted from Creighton Model Fertility Care System (CrMs) scale, calculated P-6 ovulation estimated day (OED) respect peak...

In order to study the hot melt extrusion process in fused deposition modeling (FDM), this mainly explores effects of printing temperature, heated block length, feeding speed on exit morphology and mechanical properties FDM printed Polylactic acid (PLA) samples. High-speed camera is used capture molten PLA just extruded nozzle. According morphology, outlet states material can be divided into fou...

abstract creating suitable classrooms that can meet the educational needs of mentally-retarded students is vitally important. the present study explores the effect of three physical characteristics of classroom environment on the creativity of educable mentally-retarded children: window view, window size, and classroom size. the participants, one hundred 9-to-11-year-old girl students, took the...

introduction: poor sensitivity and poor signal to noise ratio because of low injected thallium dose and presence of scattered photons are the main problems in using thallium in scintigraphic imaging of the heart. scattered photons are the main cause of degrading the contrast and resolution in spect imaging that result in error in quantification. thallium decay is very complicated and photons ar...
