Method of moments analysis of slotted waveguide antenna arrays
Altuntaş, Abdülkerim; Alatan, Lale; Department of Electrical and Electronics Engineering (2014)
Slotted waveguide antenna arrays are used extensively in many applications because of their high power handling capability, planarity, low loss and reduced profile. After the synthesis of such an array, the design should be verified by analyzing the array with an efficient simulation tool which is accurate, fast and flexible. Although FEM (Finite Element Method) based commercial softwares are very accurate and flexible, they are not sufficiently fast especially when it comes to optimization and fine tuning....
Method for Dynamic Material Property Characterization of Soft-Tissue-Mimicking Isotropic Viscoelastic Materials Using Fractional Damping Models
Martin, Bryn A.; Kutluay, Umit; Yazıcıoğlu, Yiğit (ASTM International, 2013-09-01)
Characterization of the mechanical properties of human-tissue-mimicking silicone elastomers is important for producing accurate tissue models for experimentation. However, the viscoelastic and frequency-dependent material properties of elastomers are difficult to quantify. We present a material characterization technique for a silicone elastomer used to mimic human soft tissue based on generalized-Maxwell-type material models with and without fractional dissipating mechanisms. The silicone specimens were pr...
Methodology for the Study of Solar Energy Effects to CO2 Balance in Tobacco Industry and Tobacco Plants
Yılmaz, Elanur (2009-01-01)
This work is the first part of a global study about the CO2 mass balance in a tobacco industry, including the CO2 sequestration in the tobacco plants,CO2 sequestration in an eucalyptus forest, solar irradiation, and the approach methodology to obtain the CO2 emission of the process in the industry. The aim of this work is to identify the variations in the CO2 sequestration through the growing of tobacco plants in Chile and consequently in many parts of the world. It is necessary to correlate the on-site mea...
Design of moving target indication filters with non-uniform pulse repetition intervals
İspir, Mehmet; Candan, Çağatay; Department of Electrical and Electronics Engineering (2013)
Staggering the pulse repetititon intervals is a widely used solution to alleviate the blind speed problem in Moving Target Indication (MTI) radar systems. It is possible to increase the first blind speed on the order of ten folds with the use of non-uniform sampling. Improvement in blind speed results in passband fluctuations that may degregade the detection performance for particular Doppler frequencies. Therefore, it is important to design MTI filters with non-uniform interpulse periods that have minimum ...
Method-of-lines solution of time-dependent two-dimensional Navier-Stokes equations
Oymak, O; Selçuk, Nevin (1996-09-15)
A novel approach to the development of a code for the solution of the time-dependent two-dimensional Navier-Stokes equations is described. The code involves coupling between the method of lines (MOL) for the solution of partial differential equations and a parabolic algorithm which removes the necessity of iterative solution on pressure and solution of a Poisson-type equation for the pressure. The code is applied to a test problem involving the solution of transient laminar flow in a short pipe for an incom...
