The purpose of this work is to provide the necessary background to design wide-band power transfer two-ports, or so-called broadband matching networks, at radio frequencies for wireless communication systems. The importance of the topic stems from the recent advances in the conceptual design and manufacturing technologies of the next-generation wireless and mobile communication systems, which will operate over ultra-wide frequency bands. In fact, for all communication systems, construction of ...

Contingency studies are indispensable tools of both the power system planning and operational studies. Real time implementation of operational problems makes necessary the use of high speed computational methods while requiring reasonable accuracies. On the other hand, accuracy of the results and the speed of calculation depend on branch outage modeling as well as solution algorithm used. This paper presents a comparison of post outage bus voltage magnitudes calculated by two meta-heuristic ...

Augmenting a Mincerian earnings function with regional data we estimate both private and external returns to education in Turkey using Instrumental Variables, Ordinary Least Squares, Quantile Regression and Instrumental Variables Quantile Regression methods. Our results indicate a median external return between 1.5% and 2.3% for 2006–2009. There is some evidence supporting the skill-biased technical change hypothesis. External returns are uniformly higher for women. We point out some policy implications.

Cooperation and strategic partnerships are the main concepts utilized in defining current Turkish-Russian relations. This new discourse indicates a fundamental transformation in bilateral relations and the removal of competition from the discourse that has been dominant in the 1990s. In addition, both actors aimed at Eurasia as the target region to further their common interests and bilateral cooperation. That represents another shift in the course of Turkish Foreign Policy making. This study aims ...

Diversity management has emerged as a unique agenda of today's corporations in the global economy. One important area of corporate diversity management is supplier diversity, which is an inclusive growth program designed to help develop under-represented businesses into competitive suppliers of corporations. A major challenge of supplier diversity is that many minority suppliers lack the capability to deliver products which the corporate buyers need. Another major challenge is that few minority ...

A sigmoidal curve y(t) is a monotone increasing curve such that all derivatives vanish at infinity. Let tn be the point where the nth derivative of y(t) reaches its global extremum. In the previous work on sol-gel transition modelled by the Susceptible-Infected- Recovered (SIR) system, we observed that the sequence {tn } seemed to converge to a point that agrees qualitatively with the location of the gel point [2]. In the present work we outline a proof that for sigmoidal curves satisfying fairly ...

If a road map had to be drawn for Computational Criticism and subsequent Artificial Literature, it would have certainly considered Shakespearean plays. Demonstration of these structures through text analysis can be seen as both a naive effort and a scientific view of the characteristics of the texts. In this study, the textual analysis of Shakespeare plays was carried out for this purpose. Methodologically, we consecutively use Latent Dirichlet Allocation (LDA) and Singular Value Decomposition ...

This paper aims to identify determinant traits of ewes by measuring their impact on lamb survival. For that, we devised a machine learning model that correlates ewe traits to lamb survival, and figured out as to which ewe traits explain the correlation and hence help us to identify the better mother. In this study, we kept pregnant ewes under 24 h observation by two researchers starting approximately three days before expected parturition dates. We conducted the study using native and crossbreed ...

Natural and manmade disasters led to the emergence of new approaches in designing our environment in the postindustrial era. Modern technological infrastructures failure to respond to the challenges from environmental hazards led the designers to restructure the landscape. This in turn, led to a shift in landscape architecture, planning and architecture discipline. In the past decade green infrastructure has been a topic for debate among practitioners and theorists across different disciplines, ...
