The number of published papers about membrane distillation (MD) has been growing exponentially and many evaluation and performance criteria are used to measure it; but, there is no established tradition or evaluation standard for them. This makes the evaluations difficult to compare, or even incomplete. This paper presents therefore a comprehensive critical review and clarification of the major...

in this paper, acceptance criteria of steel building code, comprehensive and quick evaluation procedures for x-bracing, are compared to each other parametrically and numerically. for this purpose, it is assumed first that the sample building is designed to meet steel building code and then by introducing transform parameters and using stress ratio of the designed components, acceptance of the d...

Performance of electrical matching of an ultrasonic transducer to the excitation generator is analyzed. The analysis is based on a transducer measured impedance. Real power supplied to the ultrasonic transducer is one of evaluation criteria. The obtainable bandwidth as well as it’s product with a real power supplied are assigned as the alternative performance evaluation criteria. Effective band...
