Indispensable Tool

Computational Electromagnetic (CEM) techniques have become an indispensable tool in efficient EM modeling, analysis and design process. EM subsurface scattering is a broad field of research with varying degree of complexity. Due level of the obscurity involved in the subsurface scattering investigation, it is therefore considered imperative to explore this problem area of EM for better insight through CEM-based study and models. In this paper, frequency domain CEM techniques are studied which have been tested to provide solution for subsurface scattering problems in terrestrial environments. The development of CEM methods for comparatively more complex problems of scattering from embedded non-metallic inhomogeneity in lossy, rough and layered media remains the focus of this article. The objective here is to provide an overview of CEM development by selecting few examples from the wide area of subsurface EM scattering.

Structural systems, which play an important role in today’s architectural education, have become an issue that is analyzed by mega structures using different disciplines in the process from the design stage to the construction stage. While design and structural system studies are performed together in practice, architecture students usually have difficulty in reflecting their learning from the structural system course into their design studio in architectural education. In this study, information about education method for "Structural System and Technologies I" course, carried out in the fourth semester (second class) in Department of Architecture in Gebze Technical University, was primarily given. Unlike previous teaching methods in this course scope, a structural system modeling to solve the given design problem was requested from the students during spring semester 2015. It was aimed to provide the students with an understanding of general design principles involving structural elements and learning about the necessity in which the structural system should be considered in conjunction with the architectural design, concluding with a two-week assignment. A survey was conducted among 55 architecture students in order to evaluate the outcomes of the assignment. According to the survey results, 61% of the students stated that function, form, and structural system affect on another. 20% of them stated that function, form, and structural system, respectively, have an order of importance in the design process. 9% of them stated that structural system determine form and function. 6 % of them stated that form, function, and structural system, respectively, have an order of importance in the design process. Finally, 4 % of them stated that their relations change depending on the condition. Innovative teaching method in this study is found to be successful because the students have experienced the importance of materials in structural system and learned how to integrate structural system course to architectural design studio. It is intended that this study will benefit architecture students and educators.

Operating Variables

A complex power system may be modeled by a system of inequalities representing the constraints imposed by the physical laws: heat transfer, energy balance, cycle efficiency and so forth. The nature of the resulting mathematical model is such that the terms contain complex expressions involving the design and operating variables of the process. With the addition of an objective function involving the cost of major system components, a multivariable nonlinear programming problem can be formulated. Seldom does the model lend itself to analytical treatment. This paper is concerned with a specific formulation and solution of nonlinear programming problems which arise in the design of ocean thermal energy conversion (OTEC) power plants. The technique used is geometric programming, GP. It is shown that GP serves as an excellent tool for system analysis because it provides sensitivity information essential to the designer.
