viability of probiotic bacteria in food during maintenance and time of consuming in food has become a challenge in food hygiene and technology and is important for representing their beneficial health effects. the aim of this study was to determine the survival of probiotic enterococcus faecium derived from koopeh cheese added to industrial iranian ultra-filtrated (uf) cheese and screening for ...

An overview of the propagation characteristics of ultrawideband (UWB) indoor radio channels is presented with an emphasis on the spatio-temporal channel properties. Extensive measurement results are provided and practical considerations are highlighted. The insight into robust UWB communications and sensor networks, provided by channel modeling, is discussed.

Ultra wideband (UWB) wireless communication has been the subject of extensive research in recent years due to its potential applications and unique capabilities. However, many important aspects of UWB-based communication systems have not yet been thoroughly examined. The area of narrow band communication is well developed. The objective of this paper is to present Ultra Wideband (UWB) communica...

Ultra-Wide Band (UWB) was presented as a promising radio technology. Because of their large bandwidth, UWB networks are supposed able to deliver high data rates at short ranges. But after analyzing measurements many works observed saturation of the number of channel Degrees of Freedom (DoF) versus bandwidth. This motivates the work presented in this paper where we focus on sub space behavior to...
