Nonlinear constrained programing problem (NCPP) has been arisen in diverse range of sciences such as portfolio, economic management etc.. In this paper, a multiobjective imperialist competitive evolutionary algorithm for solving NCPP is proposed. Firstly, we transform the NCPP into a biobjective optimization problem. Secondly, in order to improve the diversity of evolution country swarm, and he...

The accuracy of target position detection in IR seeker depends on the accuracy of tracking error signal (TES) extraction from seeker Field of View (FOV). The type of reticle inside the seeker determines the output modulation signal that carries the TES. In this paper, the stationary wagon wheel reticle is used, which makes the type of the output signal as FM modulation in the linear region of F...

In present study, a three-step multi-objective optimization algorithm of cyclone separators is catered for the design objectives. First, the pressure drop (Dp) and collection efficiency (h) in a set of cyclone separators are numerically evaluated. Secondly, two meta models based on the evolved Group Method of Data Handling (GMDH) type neural networks are regarded to model the Dp and h as the re...

In this paper, using neural networks based on radial basis functions (RBF), a comprehensive closed-form solution for effective length of vertical grounding rod is extracted in such a way that the two effects of ionization and dispersion are simultaneously considered. In creating the model, training data are computed from multi-conductor transmission line (MTL). As a results, firstly in the prop...

As the coronavirus disease 2019 (COVID-19) pandemic continues to unfold there is an untold number of trade-offs being made in every country around the globe. The experience in the United Kingdom and Canada to date has not seen much uptake of health economics methods. We provide some thoughts on how this could take place, specifically in three areas. Firstly, this can involve understanding the i...

In this paper, Burr-type XII ̄X synthetic schemes are proposed as an alternative to the classical ̄X synthetic schemes when the assumption of normality fails to hold. First, the basic design of the Burr-type XII ̄X synthetic scheme is developed and its performance investigated using exact formulae. Secondly, the non-side-sensitive and side-sensitive Burr-type XII ̄X synthetic schemes are int...

The purpose of this paper is to analyse the dynamics of cohabitation and functional impairments among older people. Our research has three main aims. Firstly, we want to analyse the effects of cohabitation on disability. Secondly, we want to study time trends in disability and cohabitation jointly to explore relationships between the two. Thirdly, we examine socioeconomic differences -as captur...

Alice wants to communicate securely to Bob in the presence of an eavesdropper Eve. There are two resources available to facilitate this. First, Alice, Bob (and Eve) have access to dependent source observations. Secondly, there is a noisy broadcast channel from Alice to Bob and Eve. Under this general source and channel setup, we are interested in three classes of problems. First, what is the se...

Irradiation of food raw materials has a double effect. Firstly, actually for which the irradiation is carried out, destruction of microorganisms is provided to increase the shelf life of products. Secondly, radiation has a danger from the point of view of the effect on the raw materials and products based on it, causing chemical transformations of constituent components by the mechanism of radi...
