Observations of the Galactic center region with the H.E.S.S. telescopes have established the existence of a steady, extended source of gamma-ray emission coinciding with the position of the super massive black hole Sgr A*. This is a remarkable finding given the expected presence of dense self-annihilating Dark Matter in the Galactic center region. The self-annihilation process is giving rise to...

In this paper, we consider a queuing model extension for a manufacturing cell composed of a machining center and several parallel downstream predestinations. In the machining center, there is an ample supply of raw material for a number of different part-types. For each type, parts are first processed in the machining center, and then in one of parallel production stations (one for each type). ...

At the 3rd Annual Ruminant Nutrition Symposium (Hammond, 1992), I reviewed the use of blood urea nitrogen (BUN) concentration for monitoring protein status in beef cattle, and discussed the potential for using milk urea nitrogen (MUN) as a noninvasive tool for monitoring protein status in dairy cattle. The purpose of this discussion is to review the basic concepts involved in urea nitrogen as a...

Maintaining the lowest possible transmission power in the wireless sensor networks (WSNs) is vulnerable to the interference fluctuations because of the bad signal-tointerference-plus-noise-ratio (SINR). The previous transmission power control (TPC) algorithms do not consider much for the interferences from other 2.4GHz devices, which can cause significant performance degradations in real world ...

The structure and properties of , heat and moisture sources and sinks of the Asian monsoon are reviewed. Results from the First GARP Global Experiment (FGGE) have yielded important information on these sources, ranging from the planetary scale down to the scale of individual convective systems. The emerging picture is one of a complex spatial and temporal distribution of heat sources over the e...
