Domestic Arrangements: The Maid's Room in the Atakoy Apartment Blocks, Istanbul, Turkey

Cataloged from PDF version of article.The first phase of Istanbul's Ataköy Housing Development, an icon of architectural modernism in Turkey, inflects modernist architectural forms with local domestic traditions. This study examines the maid's room, a sphere of the Turkish modern interior where post-war ideas and ideals both reconciled and contradicted the customary and the modern. The case study extends recent attempts to re-think postwar architectural culture and its global effects

Electromagnetic scattering solution of conducting strips in layered media using the fast multipole method

Cataloged from PDF version of article.The fast multipole method (FMM) is applied to the solution of the electromagnetic scattering problems in layered media for the first time. This is achieved by using closedform expressions for the spatial-domain Green’s functions for layered media. Until now, the FMM has been limited to the homogeneous-medium problems. An integral equation based on the two-dimensional scalar Helmholtz equation is solved to compute the electromagnetic scattering from sample geometries of conducting strips in layered media in order to demonstrate the accuracy and the efficiency of the new method

Blended learning in design education: an analysis of students' experiences within the disciplinary differences framework

Cataloged from PDF version of article.Blended learning has already become an indispensable part of education in many fields. However, the majority of existing research on blended learning has assumed homogeneity of disciplines. This study suggests that research highlighting disciplinary effects and differences is much needed to effectively develop courses and tools consonant with the characteristics of each discipline. To help close this research gap, this paper focuses on design education and analyses student experiences in a "blended design studio" that combined the Moodle learning management system, live videoconferencing, and social networking media (Facebook) with traditional face-to-face learning (design studio). Students' perceptions of the methods and tools were elicited through structured and open-ended questions and qualitative variations in responses were categorised. Subsequent quantitative analysis revealed that the characteristics of soft-applied fields require customisation in blended courses and educational system designs in several ways

An efficient method for electromagnetic characterization of 2-D geometries in stratified media

Cataloged from PDF version of article.A numerically efficient technique, based on the spectral-domain method of moments (MoM) in conjunction with the generalized pencil-of-functions (GPOF) method, is developed for the characterization of two-dimensional geometries in multilayer planar media. This approach provides an analytic expression for all the entries of the MoM matrix, explicitly including the indexes of the basis and testing functions provided that the Galerkin’s MoM is employed. This feature facilitates an efficient modification of the geometry without the necessity of recalculating the additional elements in the MoM matrix. To assess the efficiency of the approach, the results and the matrix fill times are compared to those obtained with two other efficient methods, namely, the spatial-domain MoM in conjunction with the closed-form Green’s functions, and a fast Fourier transform algorithm to evaluate the MoM matrix entries. Among these, the spectral-domain MoM using the GPOF algorithm is the most efficient approach for printed multilayer geometries

Antecedents of Expatriate Spouse Adjustment: An Analysis of Japanese Spouses in the United States

This is one of the first studies investigating factors related to the adjustment of expatriate spouses. The study extends, both conceptually and methodologically, the limited research on spouse adjustment by testing the effects of language profciency and educational level on adjustment. Furthermore, it is the first study to survey non US respondents in their native language. In the end, we found that time since arrival, educational level, language proficiency, and willingness to communicate are directly related to spouse adjustment

Algebraic acceleration and regularization of the source reconstruction method with the recompressed adaptive cross approximation

We present a compression algorithm to accelerate the solution of source reconstruction problems that are formulated with integral equations and defined on arbitrary three-dimensional surfaces. This compression technique benefits from the adaptive cross approximation (ACA) algorithm in the first step. A further error-controllable recompression is applied after the ACA. The numerical results illustrate the efficiency and accuracy of the proposed method. © 2014 IEEE

MLFMA memory reduction techniques for solving large-scale problems

We present two memory reduction methods for the parallel multilevel fast multipole algorithm. One of these methods uses data structures out of core, and the other parallelizes the data structures related to input geometry. With these methods, large-scale electromagnetic scattering problems can be solved on modest parallel computers. © 2014 IEEE

A modified equivalence principle for open surfaces

We introduce a new method for expanding equivalent surface current densities over open surfaces. The new method is based on the equivalence principle, which is theoretically used with closed surfaces. Utilizing low-order basis functions to compute the expansion coefficients of equivalent surface currents and then weighting these coefficients with an appropriate window function compensates for computational field errors originating from using truncated currents at the open boundaries. These modified coefficients can be used to reproduce the original electromagnetic fields inside a limited equivalent region. The simulations demonstrate that relative errors as low as 1-2.5% are achievable based on the specifics of the source and shape of the open surface. © 2014 IEEE
