In this paper, a new analytical design technique for three-section wideband Wilkinson power divider is presented. The proposed utilizes the dual-frequency behavior of commensurate transmission lines even-mode analysis and contributes set completely rigorous equations odd-mode analysis. Measurement fabricated prototype utilizing shows an excellent return-loss (>16 dB), insertion loss (<3.3...

This article reviews modern analytical instrumentation in forensic toxicology for identification and quantification of drugs and toxins in biological fluids and tissues. A brief description of the theory and inherent strengths and limitations of each methodology is included. The focus is on new technologies that address current analytical limitations. A goal of this review is to encourage innov...

Analytical target cascading is a relatively new methodology for the design of engineering systems. Analytical target cascading deals with the issue of propagating desirable top-level product design speciŽ cations (or targets) to appropriate targets at lower levels in a consistent and efŽ cient manner. Most existing problem formulations for multilevel design often exhibit convergence difŽ cultie...

This study aims at providing recommendations concerning the validation of analytical protocols by using routine samples. It is intended to provide a case-study on how to validate the analytical methods in different environmental matrices. In order to analyze the selected compounds (pesticides and polychlorinated biphenyls) in two different environmental matrices, the current work has performed ...

Linking enterprise-wide business decision making with engineering decision making is demonstrated by integrating the enterprise utility optimization and the engineering product development approach under a multilevel optimization framework. The analytical target cascading process is used to set the right targets for the engineering design process that maximize utility at the enterprise level. A...

Analytical solutions for constant-rate pumping tests are widely used to infer aquifer properties. In this note, we implement a methodology that approximates the time-varying pumping record as a series of segments with linearly varying pumping rates. We validate our approach using an analytical solution for a sinusoidally varying pumping test. We also apply our methodology to analyze synthetic t...

Cognitive Science talks about internal processes and representations of intelligent agents. Since we ourselves are the best examples of such intelligent agents, observation from inside (introspection) is useful. However introspection violates objective criteria required for analytical science. On the other hand, observation from outside has only limited access to internal processes and represen...

The paper proposes an analytical method for determining basic traffic characteristics of systems servicing multi-rate overflow traffic streams generated by a finite number of sources. In particular, we describe an optimum solution for the implementation of telephony system. Analytical results of blocking probability calculated using the presented methodology has been compared with the data obta...

We evaluated analytical factors such as antibody specificity, standard materials, and methodology for the measurement of C3. Mancini-type radial immunodiffusion and immunonephelometry were shown to give comparable data if variables other than procedural variables are eliminated. The most significant analytical factors affecting the measurement were antiserum specificity and source of standard m...

Finding repetitive subsequences in genome is a challengeable problem in bioinformatics research area. A lot of approaches have been proposed to solve the problem, which could be divided to library base and de novo methods. The library base methods use predetermined repetitive genome’s subsequences, where library-less methods attempt to discover repetitive subsequences by analytical approach...
