Typically used simplified error measures, like mean-squared-error (MSE), do not reveal everything about the clinical quality of lossy compressed medical signals. Errors have to be interpreted via essential medical parameters. The medical parameters depend on the type of the signal and only the preservation of essential medical parameters can guarantee the correct clinical quality. In this study...

invention of satellite and the use of it in the broadcasting technology ,evolved the broadcasting organizations activities. on one hand, it developed the scope of broadcasting geographically and to some extent solved the limitations and problems of transmitting signals such as difficulties in receiving the signals in mountainous or wood areas. on the other hand, the use of satellites on transmi...

We proposed Text-To-Speech (TTS) synthesis system based on phonetic concatenation for unrestricted input text. The input text is first converted into phonetic transcription using Letter-to-Sound rules. For synthesis of a new speech, TTS system selects the recorded phoneme units (PUs) from database and modifies the duration according to the rule based on spelling using Time Domain Pitch Synchron...

Udder Injuries often reduces the milk yield and the sustainability of economic returns. Ultrasonography was deployed to study the nature and number of  stulous tract, which developed as a consequence to mid gestational teat injury in afourth parity Jersey crossbred.Teat ultrasonography revealed the discontinuity of teat wall with a singular  stular tract on the lower one third of the left for...

background: behavioral risk factors are responsible for a substantial portion of chronic disease. educating patients is a professional responsibility of medical practitioners. however, it has been observed that physicians did not practice what they preach. we aimed to study whether medical colleges inculcate health‑promoting lifestyle among medical students during their stay in medical colleges...

In a previous paper, two of the authors presented a " regulated " picture of eternal inflation. This picture both suggested and drew support from a conjectured discontinuity in the amplitude for tunneling from positive to negative vacuum energy, as the positive vacuum energy was sent to zero; analytic and numerical arguments supporting this conjecture were given. Here we show that this conjectu...

background: various techniques are used in diagnosing cardiac diseases. the electrocardiogram is one of these tools in common use. in this study vectorcardiogram ) vcg ( signals are used as a tool for detection of cardiac ischemia. methods: vcg signals used in this study were obtained form 60 patients suspected to have ischemia disease and 10 normal candidates. verification of the ischemia had ...

introduction in recent years methods based on radio frequency waves have been used for detecting breast cancer. using theses waves leads to better results in early detection of breast cancer comparing with conventional mammography which has been used during several years. materials and methods in this paper, a new method is introduced for detection of backscattered signals which are received by...

A class of piecewise continuous, piecewise C1 transformations on the interval J c R with finitely many discontinuities n are shown to have at most n invariant measures. 1. The way phenomena or processes evolve or change in time is often described by differential equations or difference equations. One of the simplest mathematical situations occurs when the phenomenon can be described by a single...

Segmentation of ultrasound images is difficult due to discontinuity and uncertainty of segmentation boundaries caused by speckle noise. Most of the ultrasound image segmentation algorithms require high computational time and do not give good results. In this paper, a novel algorithm for the ultrasound image segmentation is proposed. Our approach is based on semi-automatic classical region growi...
