My research generally revolves around analysis of data and utilization of statistical, machine learning, and data mining techniques in a wide range of real life situations. The emphasis of my thesis work over the past few years is wireless networking, specifically, localization in Wireless Local Area Networks (WLANs) and sensor networks. In the rest of this statement, I focus on describing this...

The IEEE network technology is the emerging standard for wireless LANs and mobile networking The fundamental access mechanism in the IEEE MAC protocol is the Distributed Coordination Function In this paper we present an analytical method of estimating the saturation throughput of wireless LAN in the assumption of ideal channel conditions The proposed method generalizes the existing LAN models a...

Abstract— The problem of real time estimating position and orientation of a moving object is an important issue for vision-based control of pan and tilt. This paper presents a vision-based navigation strategy for a pan and tilt platform and a mounted video camera as a visual sensor. For detection of objects, a suitable image processing algorithm is used. Moreover, estimation of the object posit...

Achieving predictable communication latency in an ad hoc IEEE 802.11 wireless local area network necessitates an approach that overcomes the impact of the underlying non-deterministic contention-based medium access control (MAC) protocol. In this paper, we assess the feasibility of using a Time Division Multiple Access (TDMA) layer above the IEEE 802.11 MAC protocol in order to achieve such pre...

this paper investigates the effect of exchange rate uncertainty on the iran’s import trade. the exchange rate ‎uncertainty series were generated utilizing the tarch model. this model analyzes the asymmetric effects. the analysis of uncertainty and asymmetry ‎of the exchange rate shows significant tarch ‎effect on iran’s exchange rates‎. the findings of the study indicate negative shocks (bad ne...

In this paper, the method of determining thermal contact resistance of wavy surfaces is discussed exactly. For determining the thermal contact resistance of real contacts, a new method has been presented. In this method, assuming a regular sinusoidal surface profile, the real contact area in terms of applied forces has been determined. Then thermal contact resistance has been calculated. Testin...

The use of third-party logistics (3PL) providers is regarded as new strategy in logistics management. The relationships by considering 3PL are sometimes more complicated than any classical logistics supplier relationships. These relationships have taken into account as a well-known way to highlight organizations' flexibilities to regard rapidly uncertain market conditions, follow core competenc...
