BACKGROUND Weight loss may contribute to the loss of lean mass with age. OBJECTIVE The objective was to evaluate the relation between weight loss or weight gain and changes in lean mass and fat mass in older adults. DESIGN We observed changes in weight and body composition during a 4-y period in 2163 men (47%) and women (53%) aged 70-79 y in the Health, Aging and Body Composition Study coho...

For pattern recognition, the weight of the feature index is very important and is usually used to measure the feature index’s importance. The weight is usually divided into two types. One is determined by the knowledge and experience of experts or individuals, and called subjective weight; the other is based on statistical properties and measurement data, and is called objective weight. In this...

This paper extends an existing cooperative multi-objective interaction programming problem with interaction constraint for two players or two agents . First, we define an s-optimal joint solution with weight vector to multi-objective interaction programming problem with interaction constraint for two players and get some properties of it. It is proved that the s-optimal joint solution with weig...

multiple objective programming (mop) problems have become famous among many researchers due to more practical and realistic implementations. there have been a lot of methods proposed especially during the past four decades. in this paper, we develop a new algorithm based on a new approach to solve mop problems by starting from a utopian point (which is usually infeasible) and moving towards the...

The present work focuses on evolving the multiple light-in-weight topologies of compliant mechanism tracing user defined path. Therefore in this paper, the bi-objective set is formulated first on the optimization frame-work in which the helper objective of maximum diversity is introduced with the primary objective of minimum weight of elastic structures. Thereafter, the evolutionary algorithm (...

OBJECTIVE The objective of the study is to examine the relationship between weight-control behaviors and self-reported sociodemographic characteristics, weight status, and perception of body weight in a large, representative sample of adolescents in the West Bank and Gaza Strip territories of Palestine. METHOD Self-report measures of sociodemographic characteristics, body weight perception, h...

Abstract Single-objective continuous optimization can be challenging, especially when dealing with multimodal problems. This work sheds light on the effects that multi-objective may have in single-objective space. For this purpose, we examine inner mechanisms of recently developed sophisticated local search procedure SOMOGSA. method solves problems based first expanding problem an additional ob...
