We have previously reported that increased numbers of Alz-50-reactive (apoptotic) neurons occurred in young DS subjects compared to controls, but increased in density with increasing age, and in advance of identifiable senile plaques (SP) in DS. The purpose of the study was to determine if there are further differences in Alzheimer's disease (AD)-like neuropathology with increasing age among in...

introduction: corrosion and scaling of water in distribution systems in spite of imposing economic and aesthetic problems can lead to adverse effects on consumers' health. the present study was conducted to evaluate the corrosion and scaling of water distribution system of sarableh city (ilam, iran) during summer and winter seasons in 2014. materials and methods: totally, 60 samples of wat...

based on langelier, corrosion index of water in the distribution system was balanced. shadegan is a city and the capital of shadegan county in khuzestan province, iran. it has an area of 3197 m2 and located 84 km south of ahvaz. water distribution system serves 70,000 people in the city and the total consumed drinking water is 28525 m3per day (3,4).this descriptive, cross sectional study examin...

The paper deals with the spectral analysis of signal formats for DS-SS CDMA WLANs. The main emphasis is put on introduction of a quantitative measure which allows for conzparisotz of different spreading codes and channel modulations from the viewpoint of a uniformity of an in-hand power distribution Such a measure is essential to compare different DS-SS CDMA systenzs performance in mitigating t...

Since the interfering signals from other users of the spectrum is a main problem in HF communication, it is necessary to consider them when evaluating HF radio systems. Based on the Laycock-Gott congestion model, a statistical HF interference model is derived and brieey compared to real measurements. The two basic methods to apply spread-spectrum modulation in radio communication are frequency-...

This paper investigates the performance of two direct sequence ultra wideband (DS-UWB) communication systems over multipath fading channels. The first system is the classic DS-UWB system and the second is obtained by adding a forward error control code (FEC), convolutional code. For the two systems, bipolar pulse amplitude modulation (BPAM) is applied. In the receiver end, the selective diversi...

This paper proposes an effective approach to solve renewable distributed generators (RDGs) and electric vehicle charging station (EVCS) allocation problems in the distribution system (DS) reduce power loss (PLoss) enhance voltage profile. The RDGs considered for this work are solar, wind fuel cell. uncertainties related modelled using probability functions (PDF). These sources’ best locations s...

The rapid development of different energy production and conversion technologies at the distribution system (DS) level facilitates integration electrical, heating, cooling DSs. planning operation integrated DSs will affect asset management transmission (TS), which in turn change electrical prices investment decisions DS level. This paper addresses a tri-level multi-stage approach for coordinate...

Testing large-scale distributed systems is a challenge, because some errors manifest themselves only after a distributed sequence of events that involves machine and network failures. DS is a checker that allows developers to specify predicates on distributed properties of a deployed system, and that checks these predicates while the system is running. When DS finds a problem it produces the se...

In this paper, we propose a direct sequence ultra wideband (DS-UWB) radar system using a short-length pseudo noise (PN) sequence. The proposed DS-UWB radar reduces the correlation processing time by averaging out the noise in the correlator outputs, and thus, employs a short-length PN sequence unlike the conventional DS-UWB radar systems using multiple variable-length PN sequences. Numerical re...
