The fast growth of the wireless communication industry poses severe limitations on radio astronomical observations. Two such examples are the Iridium system which will probably cause problems within bands reserved to radio astronomy and the GSM system which became ubiquitous and thus prevents observation in its band. In this paper we present the results of blanking of interfering signals measur...

In Orthogonal Frequency Division Multiplexing (OFDM) system, in order to reduce the influence of Co-Channel Interference (CCI), Minimum Mean Square Error-Adaptive Array Antenna (MMSE-AAA) is attractive. To get the space diversity gain, the distance between adjacent elements should be set to be more than several wavelengths. However, it is difficult to derive the optimal weights with a few train...

In this study, dynamic bearing capacity of adjacent shallow strip foundations located on sandy soil was examined using a numerical finite difference modeling, FLAC. The behavioral interference of shallow strip foundations under different conditions was investigated. The effect of soil strength parameters, geometric characteristics of shallow foundations and cyclic loads at different distance ra...

Introduction: There are two alternative explanations of the Stroop phenomenon. Several studies have revealed that the difference in performance on congruent and incongruent trials can arise from response interference. On the contrary, many authors have claimed that Stroop interference might occur at earlier processing stages related to semantic or conceptual encoding. The present study aims to ...

The most commonly used empirical approach to address issues of attention constraint is evaluate the degree of interference in dual or multiple tasks. The purpose of this study was designing software to estimate the relative interference between multiple tasks and determine its validity in performance prediction of simultaneous multiple tasks. in order to assess the validity of software, 46 stud...

Healthcare industry has unique characteristic about human’s life. Any mistake or medical error will cause the irretrievable regret. Patient safety is the most important issue in recent years. Because the uncertainly of disease occur, the demand of healthcare need, location and types are changed frequently. By the presure of “Self Management Plan”, how to make limited healthcare more effectivene...

The vulnerability of civil GPS receiver to interference may be intentional or unintentional. Among all types of interference, replay attack intended as the most dangerous intentional one. The signal structure of replay attack is almost the same with the satellite signal. The interference effects can be reduce with the design of an appropriate filter in the receiver. This paper presents two meth...

the modeling investigation in this paper discusses the system level effects of a toxicant on a three species food chain system. in the models, we have assumed that the presence of top predator reduces the predatory ability of the intermediate predator. the stability analysis of the models is carried out and the sufficient conditions for the existence and extinction of the populations under the ...
