American Economy

Industry, regardless of its role in the American economy is suffering from the dramatic leap in energy costs. Unfortunately many of us do not realize how much of our profits are being devoured by these ever increasing costs. The misguided philosophy is that energy costs are absorbed in the maintenance budget. The maintenance budget generally is not broken down therefore the true operating costs of the energy used can not be determined. Some companies are still operating on the concept of cheap energy. If energy costs were broken down into a separate budget it will soon become apparent that the energy costs are becoming more and more a factor in evaluating the true cost of producing a product. The companies that have recognized this condition are finding it extremely difficult to absorb these costs and are adjusting their product pricing accordingly. Energy costs are spiraling upward and companies must analyze the equipment consuming this precious commodity. The boiler room is the greatest consumer of energy. If a company is going to pursue the path of energy conservation, the boiler room will be the focal point because “Energy Conservation Begins In The Boiler Room”. Paper published with permission.

The Impact

The paper shows a method of optimizing local initiatives in the energy sector, such as energy cooperatives and energy clusters. The aim of optimization is to determine the structure of generation sources and energy storage in order to minimize energy costs. The analysis is carried out for the time horizon of one year, with an hourly increment, taking into account various RES (wind turbines (WT), photovoltaic installations (PV), and biogas power plant (BG)) and loads (residential, commercial, and industrial). Generation sources and loads are characterized by generation/demand profiles in order to take into account their variability. The optimization was carried out taking into account the technical aspects of the operation of distribution systems, such as power flows and losses, voltage levels in nodes, and power exchange with the transmission system, and economic aspects, such as capital and fixed and variable operating costs. The method was calculated by sixteen simulation scenarios using Mixed-Integer Linear Programming (MILP).

A timely response to a fluctuating and ever-changing consumer demand is an important decision for a company, as it may impact its position in the market. Thus, proper inventory management becomes a focal point in retail business process management and can provide a substantial competitive advantage. In this paper, we introduce a modified version of Wilson’s model, which takes into account trends in consumer demand and offer flexibility in reordering time. The illustration of the proposed model is presented, showing the significant economic benefit under particular conditions.

Equilibrium Configurations

The two dimensional motion of a generally non-circular non-uniform cylinder on a flat horizontal surface is investigated. Assuming that the cylinder does not slip, energy conservation is used to study the motion in general. Points of returns, and small oscillations around equilibrium configuration are studied. As examples, cylinders are studied for which the cross section is an ellipse, with the center of mass at the center of the ellipse or at a focal point, and the frequencies of small oscillations around their equilibrium configurations are found. The conditions for losing contact or sliding are also investigated. Finally, the motion is studied in more detail for the case of a nearly circular cylinder.

This case concerns and discusses how a company can shape its growth strategy, given the current competitive environment and increasing operating costs. The case will help students to realize the important of aligning its business objectives with its operations. The food industry is facing declining profit margins due to fierce competition internally and also from overseas competitors. It is, therefore, important to align its strategies with its operations to grow its revenue while reducing its operating costs.

Pneumatic linear drives are widely used in manufacturing, mainly for handling tasks. Pneumatic drives are very versatile and reliable. They are easy to install and to maintain as well as economically priced. Due to rising interest in environmental matters and increasing energy costs, energy efficiency has become a major issue in industrial applications. There is a growing competition between pneumatic and electromechanical drives. Pneumatic drives are said to have high operating costs while the purchase of electromechanical drives is more expensive. The operating costs of pneumatics are mainly induced by the energy consumption to provide pressurized air. Therefore many different air saving measures for simple handling tasks are proposed in literature, which offer opportunities for reducing the air consumption in comparison to standard configurations. This paper provides an overview of different approaches for saving air and typical applications for these approaches. The thermodynamic concept of exergy is utilized in the paper. It provides a better standard of comparison between different technologies than common energy analysis because exergy accounts for a system’s ability to conduct work out of different forms of energy. An exergy based analysis and a comparison of different air saving circuits are presented. The approaches described in literature are suitable for different applications. The study includes an analysis of cross flow valves to recuperate parts of the exhaust air during backstroke. Furthermore shut-off-valves using the expansion energy saved in the pressurized air of meter-out controlled cylinders are evaluated. The use of expansion energy is applicable if the entire cylinder force is not required at the end stop. The circuits are simulated based on lumped parameter models (DSHplus). The simulations are validated by experiments. The exergy efficiency of the examined circuits is compared to a meter-out controlled standard drive. Furthermore possible restrictions for the use of these circuits are discussed. This includes stability problems caused by the reduced force in the end stop or influences on the drive dynamics. If these restrictions are considered in the design of the facility, the same level of process quality and reliability compared to a standard setup can be achieved. Large energy savings and therefore reductions of operating costs of the pneumatic drives are possible with limited effort.

The paper presents the results of a theoretical study of the use of a booster pump. The task of substantiating the use of a booster pump with an electric drive and a long-range sprinkler apparatus at the extreme section of the sprinkler machine in comparison with the whole section is set in the work. Energy costs, an indicator of cost and operating costs are considered as indicators of comparison. Based on theoretical studies, the application areas of the booster pump were found for operating costs, taking into account the indicators of energy consumption, reliability and cost, calculated for 10 years of operation.

One of the primary benefits of sustainable retail over the long run has to be the marketing gain from having something other competitors do not: lower operating costs, a more socially responsible public profile, ease of gaining planning approval for new projects, better access to certain investment pools, higher rents (in the case of developers), ease of recruiting and retaining key people. Each of these benefits needs marketing and public relations support; each benefits from a clear and consistent corporate message that promotes sustainable retail.To date, there are very few retailers or developers who have championed sustainability long enough, consistently enough and with enough actual demonstration of changes in standard operations to gain the benefits of green marketing, but the very paucity of examples serves to underscore the point: the green marketing space is wide open for large retailers and developers.What would be the marketing steps that a company could take to benefit from its “sustainability focus?” The key to any marketing program is to differentiate a company’s actions from those of competitors and to do it along lines that its various stakeholders care about. This practice of differentiation is often expressed as “finding a difference that makes a difference, to someone who makes difference to you.”For retail developers, the first differentiator should be to attract more and better tenants to all of their centers, tenants who value lower operating costs and the developer’s program of sustainable development and corporate social responsibility.

Energy conservation has long been a focal point in hibernation research. A long-standing assumption is that ambient temperature (Ta) largely defines the rate of energy expenditure because of well-known relationships between Ta, metabolic rate, and frequency of arousal from torpor. Body condition and humidity also affect energy expenditure but are usually considered secondary factors. We held bats in captivity under multiple environmental conditions to directly compare the importance of Ta, fat mass, and humidity for energy expenditure of hibernating tricolored bats (Perimyotis subflavus). Fat mass was the best predictor of female mass loss, followed by Ta and humidity. However, males had less fat and adopted a more energetically conservative hibernation strategy. Our results demonstrate that understanding the evolution of behavior, physiology, and ecology of hibernation requires disentangling the relative contributions of multiple drivers of hibernation energetics, and that Ta is not always the most important factor driving energy expenditure.
