deducing what a paper is about, titles are considered as the most important determinant of how many people will read the article. therefore, studying the use of different syntactic structures and their rhetorical functions in titles is of great significance. the current study was set to investigate these structures used in research article titles in three disciplines of applied linguistics, den...

In this paper, an adaptive transmit power allocation (TPA) scheme is proposed for Vertical Bell Labs Layered SpaceTime (V-BLAST) system with delayed channel state information (CSI) feedbacks. At the transmitter, the suboptimal adaptive power allocation scheme is presented to minimize bit error rate (BER) with total power constraint. At the receiver, the zeroforcing (ZF) rule is employed for sig...

Abstract – This paper presents a novel model based design process for mechatronic systems. The process is based on VDI 2221 and VDI 2206 principles and compatible with systems engineering management. The process presented consists of clear recursive and iterative phases which each provide formal and interoperable outcomes which enable efficient ability to re-use and re-cycle designs. Even thoug...

A 120o optical hybrid based on 3x3 multimode interference coupler is reported. The device exhibits less than 10o phase deviation over 55 nm in the Cand L-band. Keywords—120-degree hybrid; multimode interference coupler;

In the paper ultimately efficient image lossless coding methods are described. They are based on least-squares adaptive prediction, possibly combined with normalized LMS algorithm. Their performance is comparable to that of TMW, and MRP 0.5 techniques, while their computational complexities are smaller than those for the two reference methods. The new algorithms are supported by an advanced ada...

In this work, a new gradient based reverse modeling approach employing Artificial Neural Networks (ANNs) for systematic RF/microwave modeling is introduced. This approach is particularly suited to modeling scenarios, where standard ANN multi-layer perceptron (MLP) fails to deliver a satisfactory model. The proposed approach detects the simplest input-output relationship inherent to the modeling...

With the switch-over to digital television in February 2009, the UHF band will become available for unlicensed use, pending the final FCC rule and order. The incumbents that need to be protected are digital television and wireless microphone signals. Some of the key requirements for an unlicensed radio to operate successfully in this band are (i) the ability to quickly and robustly sense spectr...

Computational challenges in genomics data mining and analysis are an impending roadblock in modern health-sciences research, where algorithms for DNA sequence processing grow alarmingly in computational needs as datasets from new instruments continue to dramatically expand. Reconfigurable computers featuring customizable processing devices (e.g. FPGAs) hold the key in addressing these challenge...

The relevance of flexibility resources in today’s energy systems is underestimated due to the conventional ideologies of operators and users, however, the recent rise in demand response popularity has allowed considerable changes to how and how should power systems operate. In this paper, it is presented an aggregator’s methodology to include and manage distributed energy resources, namely, dis...
