this article is arranged based on a research plan which its goals is evaluation of the possibility of applying flexible human resource structure in industrial organizations. in this research, applying conditions of just in time (j.i.t) and flexible manufacturing systems (f.m.s) have brought up as a pioneer flexible movements in industrial units and based on based two phenomenon, the nescessity ...

conclusions temperaments can provide a basis to classify psychiatric disorders. psychiatric disorders can be placed in a spectrum based on temperaments. results four groups of temperaments were identified: high active, high flexible; high active, low flexible; low active, low flexible; and low active, high flexible. when temperament deteriorates personality, non-psychotic, and psychotic psychia...

objective: this study was conducted to compare the results of fixed versus flexible gnrh antagonist protocols in controlled ovarian stimulation for intra cytoplasmic sperm injection (icsi) in patients with pcos. materials and methods: a randomized clinical trial was performed on 100 pcos women, who were admitted to a tertiary infertility clinic and were candidate for ivf/icsi. they were divided...

A desired characteristic of future spacecraft and space structures is the possibility of reducing the costs inherent with their transport in the space. Hence, it is necessary to decrease their weight; the main drawback consists of the decreased rigidity of the structure. Therefore, the elimination of vibrations becomes an important issue in spacecraft maneuvers. Another issue, related to the pr...

Rutting is one of the major load-related distresses in airport flexible pavements. Rutting in paving materials develop gradually with an increasing number of load applications, usually appearing as longitudinal depressions in the wheel paths and it may be accompanied by small upheavals to the sides. Significant research has been conducted to determine the factors which affect rutting and how th...

Figure 1: Principle of habitat modelling: sampling of species distribution data (here: presence-absence data) and selected predictor variables; estimating an empirical, predictive model (in this case: by logistic regression a generalised linear model for binary response variables, other, more flexible approaches are generalised additive models, classification and regression trees, artificial ne...

We describe a matching algorithm for terms built over flexible arity function symbols and context, function, sequence, and individual variables. The algorithm is called a context sequence matching algorithm. Context variables allow matching to descend in term-trees to arbitrary depth. Sequence variables allow matching to move in term-trees in arbitrary breadth. The ability to explore terms in t...

This paper presents an optimization-based solution approach for the dynamic multi-level capacitated lot sizing problem (MLCLSP) with positive lead times. The key idea is to solve a series of mixed-integer programs in an iterative fix-and-optimize algorithm. Each of these programs is optimized over all real-valued variables, but only a small subset of binary setup variables. The remaining binary...
