Snoring detection is important for diagnosing obstructive sleep apnea syndrome (OSAS) and other respiratory sleep disorders. In general, audio signal processing such as snoring sound analysis uses the frequency characteristics of the signal. Recently, a correlational filter Multilayer Perceptron neural network (f-MLP) has been proposed, which has the first hidden layer of correlational filter o...

We present principles for guessing clubs in the generalized club filter on Pκλ. These principles are shown to be weaker than classical diamond principles but often serve as sufficient substitutes. One application is a new construction of a λ-Suslin-tree using assumptions different from previous constructions. The other application partly solves open problems regarding the cofinality of reflecti...

Myocardial perfusion SPECT imaging with Tc99m-sestamibi is the most accurate non-invasive means of detecting coronary artery disease and assessing the severity of perfusion abnormalities in the patients with coronary stenosis. Though simple and straight forward the results produced by the technique is very much affected by the details being used. One of the main problems with the test, wh...

Periodic noises are unwished and spurious signals that create repetitive pattern on images and decreased the visual quality. Firstly, this paper investigates various methods for reducing the effects of the periodic noise in digital images. Then an adaptive optimum notch filter is proposed. In the proposed method, the regions of noise frequencies are determined by analyzing the spectral of noisy...

Strategically positioned along lymphatic vessels, lymph nodes act as filter stations preventing systemic pathogen dissemination; they are primary sites of innate immune responses and provide the staging grounds for the generation of adaptive immunity. Critical mediators of these lymph node functions are two phenotypically and functionally distinct subsets of macrophages: the subcapsular sinus m...

In Bayesian peer-to-peer decentralized data fusion, the underlying distributions held locally by autonomous agents are frequently assumed to be over same set of variables (homogeneous). This requires each agent process and communicate full global joint distribution, thus leads high computation communication costs irrespective relevancy specific local objectives. work formulates studies heteroge...

introduction: one of the main complications of hemodialysis in patients with chronic renal failure is hypoxemia which is related to several factors including the type of filter. the aim of this study was to evaluate the hypoxemia levels in patients undergoing hemodialysis with focus on the type of filter. methods: in a crossover clinical trial, 29 patients from emodialysis ward of fatemieh hosp...

one of the common problems in reflection seismic records in the land is the existence of surface waves with high amplitude and low frequency which cause the most important parts of reflective signals to be masked. therefore, it is necessary to attenuate them by processing and acquisition methods. as it is impossible to attenuate the surface waves completely, and sometimes it is likely to damage...
