In order to reduce the influence of measurement errors on the received signal strength of node localization of wireless sensor network, this paper presents a difference correction RSSI location algorithm of double reference nodes (DRN-RSSI). Firstly, DRN-RSSI selects two nearest beacon nodes away from the unknown node as differential reference node. Then, it measures the coordinate of reference...

Tribulus terrestris is used as a urinary anti-infective in folk medicine. To validate this use, the in vitro antibacterial activity of methanolic extracts of different parts (fruits, stems plus leaves and roots) of T. terrestris L. growing in Iran was evaluated against four reference bacteria by broth dilution assay and agar diffusion assay. The MIC value of the methanolic extracts of fruits an...

This paper presents a new control method for simultaneous compensation of instantaneous reactive power and current harmonics by parallel active filters (PAFs). Reference compensating currents of PAF are calculated using the subtraction of instantaneous power from its average value. In this way, it is possible omitting high/low pass filter(s) from the control circuit of PAF, which usually result...

In this paper, a new low-VDD CMOS bandgap reference circuit with small layout area and low power consumption is proposed. The proposed circuit delivering its output voltage below 1V has its Proportional-To-Absolute-Temperature (PTAT) term compensated by the Complementary-proportional-To-AbsoluteTemperature (CTAT) voltage thereby suppressing a change in its output voltage regardless of temperatu...

the percentage of strains of stn plrylococcus .t1lln'us that can be typed with the basic set phages has fallen in recent years (1,2)). it appears, therefore, that all increasing proportion of stcphvlococci, for whatever reason, arc unsuscepriblc to the basic set phages and it is essential that new phages be introduced if the situation is to be improved. seven new phages have ben issued by the i...

The concept of Reference Architectures is novel in the business world. However, many architects active in the creation of complex systems frequently use the term Reference Architecture. Yet, these experienced architects do not collectively have a consistent notion of what constitutes a Reference Architecture, what is the value of maintaining the Reference Architecture, what is the best approach...
