Industry in Ukraine is among the world’s most energy intensive. Energy was plentiful and cheap in Soviet times and little effort was made to conserve it. Rising energy prices have had a major impact on profits and production, which also creates a tremendous market potential for energy efficient products and services. Yet Ukrainian industry has not implemented significant energy efficiency measu...

The neoclassical theory of investment implies that expected stock returns are tied with the expected marginal benefit of investment divided by the marginal cost of investment. Winners have higher expected growth and expected marginal productivity (two major components of the marginal benefit of investment), and earn higher expected stock returns than losers. The investment model succeeds in cap...

The relationship between the quality of finishing works, costs, market value, and profit, is presented and explained for residential buildings. The results show that the higher quality of finishing works increases profit for investors. As the maximum market price is limited, there is a limit when the investment in finishing work is no longer cost-effective as, after increase in costs, the marke...

In this paper, we develop an economic order quantity (EOQ) model for fixed shelf-life items and a non-increasing demand. The objective of is to maximize the total profit. We find criterion decide (i) interior maximum solution or (ii) boundary solution. Eight numerical examples are given illustrate all possible scenarios generalized model. Our results identify scenario which profit always negati...

This paper presents a simple method based on strain energy density criterion to study the crack initiation angle by finite element method under biaxial loading condition. The crack surface relative displacement method is used to eliminate the calculation of the stress intensity factors which are normally required. The analysis is performed using higher order four node quadrilateral element. The...

BACKGROUND The proportion of Australian adults achieving physical activity levels believed to be sufficient for colon cancer prevention was estimated, and sociodemographic correlates (age, gender, educational attainment, occupation, marital status, and children in household) of meeting these levels of activity were analyzed. METHODS Data from the 2000 National Physical Activity Survey were us...

This paper proposes a novel region-based method for image segmentation, which is able to deal with intensity inhomogeneities in the segmentation. Intensity inhomogeneity often occurs in real-world images, which presents a considerable challenge in image segmentation. Here we can take both mri images and also satellite images. First, based on the model of images with intensity inhomogeneities, w...

We consider a model of exploitation of a size-structured population when the birth, growth and mortality rates depend on the individual size and interspecies competition, while the exploitation intensity is a function of the size only. For a given exploitation intensity and under natural assumptions on the rates, we establish existence and uniqueness of a nontrivial stationary state of the popu...

The CGPS of the woodwork of a public university was observed and analyzed. Apart from what is usual in the field of Ergonomics' studies, it is an academic context, where there is not a direct implication of profit, productivity and clientele. The group tried to sever negative and broadcasted opinions about the place by analyzing it from a different point of view. This work was considered releva...

Pasture systems for grass-fed beef production in the Gulf Coast region were evaluated for profitability and sustainability over the period 2009/2010 to 2011/2012. May-weaned steers were divided into groups and randomly placed into different pasture systems. Data on input usage, output quantities, and carbon emissions were recorded and analyzed. The least complex grazing system yielded higher pr...
