Consumption awareness for energy savings: NIALM algorithm efficiency evaluation

Energy-efficiency of server hardware, web server software and databases has been widely studied. However, studies that combine these aspects are rare. In this paper the authors present an energy-efficiency evaluation of a web and database application. They concentrate on the following aspects: server BIOS and operating system energy optimization and “bursting” i.e. queuing requests and then executing them in bursts. The authors have used the bursting method with both a database application and a web plus database application. Their results indicate about 10% energy savings using this method. They analyse the model by statistical tools and present an equation to express the quality of service versus burst wait time relationship.

The production ?congestion? phenomenon is widespread in reality although few models nowadays consider its influences. In this study, production congestion is introduced into an environmental efficiency evaluation model and a new data envelopment analysis model that considers both production congestion and undesirable output is established so as to measure environmental efficiency evaluation effectively. On this basis, we divide technological change into productive technological change and energy-savings emission reduction technological change to establish their influences on the congestion phenomenon. The results show that productive technological change cannot relieve the degree of congestion while green technology change that stimulates environmental efficiency improvement can greatly alleviate situations of congestion.

Evaluation Approach

The Forced Invariance Method (FIM) is a vegetation suppression algorithm for multispectral images which is of great interest since it uses statistics collected only from the pixels of the image itself. Due to this a priori spectral characteristics of the captured objects are not required. For using the FIM or its modification in practice it is necessary to have some way to evaluate algorithm efficiency in order to analyze the results of experiments. This paper presents the method designed to solve this problem. Presumably, it is suitable for evaluating various algorithms, such as those designed to suppress vegetation. The proposed method is based on the idea of comparing a processed image with its standard using the similarity measure.

Copenhagen summit results could be called a failure. This is the failure of UN climate change policy management, but definitely the first step to a new order as well. The article reviews main characteristics of climate policy paradigm shifts. Russian interests in climate change policy and main threats are analyzed. Successful development and implementation of energy savings and energy efficiency policy are necessary and would sufficiently help solving the global climate change problem.

Production Part

Pilot data indicate that wood chip pretreatment with oxalic acid reduced the specific energy required to make thermomechanical pulp. A combined oxalic acid/bisulfite treatment resulted in 21% refiner energy savings and 13% increase in brightness for aspen. A low level of oxalic acid treatment was effective for spruce. Energy savings of 30% was observed with no significant change in strength properties. Adding bisulfite did not significantly increase the brightness of the spruce pulp. For pine, the optimum treatment was a moderate level of oxalic acid, which resulted in 34% energy savings and an increase in strength properties. For all of these treatments 1–3 w/w % carbohydrates were recovered, which can be fermented to produce ethanol. The extract sugar solution contained significant quantities of arabinose.
