the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...

The paper presents a coaxial-like sensor operating in the 20 Hz-2 MHz frequency range used to determine the electrical properties of selected liquids of low electrical conductivity. Examined materials included low-concentrated aqueous solutions of potassium chloride, sodium chloride and trisodium citrate, which are common food additives. Impedance spectra of the measurement cell filled with par...

This paper examines the importance of load phase angle variations with respect to fatigue damage. The operating loads on a generic three bladed up-wind 1.5-MW wind turbine blade were analyzed over a range of operating conditions, and an aggregate probability distribution for the actual phase angles between the peak in-plane (lead-lag) and peak out-ofplane (flap) loads was determined. Using a fi...

Background. We aimed to study the molecular characteristics and clonal structure of carbapenemase-producing Enterobacteriaceae(CPE) in post-acute care facilities (PACF’s) in Israel and to analyze the temporal changes that have occurred between 2008 and 2013. Methods. The prevalence of CPE carriage in PACF’s in Israel was determined in two point prevalence national surveys done in 2008 and 2013....

As new code-based defense technologies emerge, attackers move to data-only malware, which is capable of infecting a system without introducing any new code. To manipulate the control ow without code, data-only malware inserts a control data structure into the system, for example in the form of a ROP chain, which enables it to combine existing instructions into a new malicious program. Current s...

This document requests the allocation of an IPv4 /10 address block to be used as Shared Address Space to accommodate the needs of Carrier-Grade NAT (CGN) devices. It is anticipated that Service Providers will use this Shared Address Space to number the interfaces that connect CGN devices to Customer Premises Equipment (CPE). Shared Address Space is distinct from RFC 1918 private address space b...

The present study evaluated the effi cacy of various culture media for performing the isolation and growth of the rubella virus inoculated into SIRC cells. Rubella virus RA-27/3 strain and RVi/SãoPaulo/BRA99 wild type strain (GenBank number DQ458965) were inoculated into SIRC cell line and cultivated in 199, DMEM, MEM and RPMI media. The inoculated cells when examined on phase contrast microsco...

The polarization resistance and capacitance of platinum black electrodes in contact with aqueous NaCl solutions was investigated. A series of measurements were made at 259/0.1 8C in the 10 Hz to 10 MHz range using a HP 4192A Impedance Analyzer. The measurement cell has flat parallel platinum electrodes 15 mm in diameter, with a continuously variable spacing from 0.5 to 9 mm. They were platinize...

We are facing the exhaustion of the IANA IPv4 free IP address pool. Unfortunately, IPv6 is not yet deployed widely enough to fully replace IPv4, and it is unrealistic to expect that this is going to change before the depletion of IPv4 addresses. Letting hosts seamlessly communicate in an IPv4 world without assigning a unique globally routable IPv4 address to each of them is a challenging proble...

In the early 1990s, the low-end customer premises equipment (CPE) such as telephone, analog modem were the major products of Taiwan communication industry, and the local small to medium size corporations had limited resources for R&D in comparison with those of foreign advanced manufacturers. As the strength of the communication industry signified the critical index of a country’s competitive e...
