für 45.80€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Many tests and consumer surveys have shown that manual dishwashing at home is done in very different ways, taking also different amounts of resources. Because almost every household, whether owning an automatic dishwasher or not still keeps on washing up a few items by hand, it seems necessary to investigate manual dishwashing regarding optimisation. Therefore, a project was run at the University of Bonn to find out an optimal way to clean the dishes by hand. Optimisation in this case means to reach a reasonably good cleaning performance with the minimum amount of resources, as water and energy for example. First, manual dishwashing was investigated experimentally: A repeatable method was developed for the sink washing process and with this method, several factorial studies were performed to find the factors in the process that influence the cleaning performance most. On the basis of the results of the experimental investigation and the knowledge - from previous studies on manual dishwashing - on how consumers wash up, Best Practice Tips were defined as an applicable guide for the consumer to save resources. In order to find out if it is possible to save resources when consumers apply the Best Practice Tips, several verification studies were run: three comparative laboratory studies, in which the test persons had to wash up different amounts of dishes, once with their usual behaviour and once by applying the Best Practice Tips. The results showed that especially with higher amounts of dishes, relevant resources of energy and water can be saved. However - possibly due to a different method existing for washing up of only a few items - no significant reduction was found when consumers were applying the Best Practice Tips with small amounts of dishes. As a next step, the possibility to save resources with the Best Practice Tips was verified in an in-home study in two countries (Germany and Spain). The findings of the previous studies could be confirmed in general. The savings of water and energy were especially high when persons usually washing up under running tap water changed their behaviour and washed up the dishes in a sink filled with water. However, the individual savings differed very much. This work delivers fundamental knowledge how resources can be saved in manual dishwashing. It is up to future studies to intensify the experimental investigation of manual dishwashing and the training with the Best Practice Tips. ····· 10361107346

With convincing reasoning and speculation, this newly established theory proposed in this paper could go through various visible phenomena and effects of frayed fibers as published earlier. This theory proposes that frayed fibers are generated based on the integration of splitting and locally high consistency mechanisms. In other words, the intensive external fibrillation responsible for splitting and locally high consistency theory is one of the most important effects of refining on frayed fiber generation. ····· 10361103044
für 71.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray The problems of airport landside capacity are of industry-wide interest. Evaluation of landside capacity enables airport operators and designers to identify passenger and baggage flows bottlenecks, find the primary cause of the bottlenecks formation and take measures mitigating the impact of bottlenecks on the airport operations. Many studies dealing with these problems are focused on the processing part of the airport terminal and consider the airport terminal to be an isolated system. Although this approach provides valuable data concerning capacity, delays or processing bottlenecks, in some cases, identified capacity constraints are only the symptoms of the actual problem. In order to identify the cause of the problem, it is necessary to consider the airport terminal as an integral part of much more complex regional or national transportation system. This book investigates the interrelationship between traffic flows within airport`s catchment area and passenger and baggage flows within the airport terminal with a view to improve the airport landside infrastructure utilisation and reduce the air pollution resulting from the high share of individual airport ground access trips. ····· 10361102936

Therefore, an early and accurate diagnosis is determinant to provide adequate treatment. While polysomnography is the preferred tool in this type of diagnosis, the exam is expensive, uncomfortable for the patient and usually it must be performed in clinical facilities. The scope of this thesis is to provide a highly portable system, an alternative to existing sleep assessment tools, supported by a physiological monitoring belt and a mobile phone connected via Bluetooth. The Mobile Acquisition Platform for Sleep Assessment (MAPSA) is an easy-to-use and interactive system, which monitors several physiological signals, as well as sleep related information, through sleep and dream e-diaries. While this system acquires a limited set of physiological data, it does not signi cantly interfere with the normal routine of the patient, which allows long time monitoring exams and the diagnosis of other types of disorders not easily detectable by the polysomnography. The MAPSA should aid sleep physicians in their daily practice. ····· 10361102751

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Lake Tana`s water balance is not well understood since a large part of the Lake Tana basin is ungauged with uncertain inflows. In recent studies by Kebede et al. (2006) and SMEC (2007) closure of Lake Tana water balance is obtained by runoff from ungauged catchments that cover a large part of the Lake Tana basin. In this thesis water balance terms are calculated on a daily base while simulated daily lake levels are compared to observed levels for the period 1995 to 2001. Daily flows from an ungauged catchment are estimated by transferring model parameters from gauged catchments using a regionalisation procedure, a spatial proximity procedure and catchment area ratio`s methods. In regionalisation gauged catchment model parameters of the conceptual rainfall-runoff model HBV are transferred to ungauged catchments based on catchment characteristics to allow for runoff simulation. In the proximity procedure model parameters of gauged catchments are transferred to neighbouring ungauged catchment. In area ratio model parameter sets of gauged catchments are transferred to ungauged catchments of comparable area. ····· 10361102454

Major problem in mine lighting is continuous changing of task place and poor surrounding reflectance. This signifies the scientific design of illumination system, which is very important for good vision, so that individuals may work therein with reasonable comfort. Also, advances in lighting technology have shown that there is a tremendous scope for energy conservation in lighting systems. Consequently, cost effective lighting installations have become synonymous with energy efficient lighting systems. Hence, a scientific approach in the illumination design would contribute to efficient lighting without much addition to the total mining project cost. In this book, design of illumination system for mine haul roads is demonstrated based on testing of large number of luminaries, which are very widely used in the mines. The results of the study given in this book provide guidelines for design of lighting system for mine haul roads, for similar operational conditions. ····· 10361102352

This problem can be decomposed into three main sections. Based on these sections, properties of the problem and the objective function within a mathematical model are defined and scheduling heuristics to cover both the multi-wire and bunching stages are demonstrated. In multi-wire stage, after acquiring an initial solution with simulated annealing technique, a scheduling solution is obtained. This solution is considered as an input for the second stage and jobs in bunching stage are scheduled with another heuristic and final result is revealed out. Final result is compared with the planners results and efficiency of the proposed heuristic method is evaluated. Heuristic algorithms proposed in this book consider the relevant sector specific constraints like tardiness to the due date, sequence dependent setup times, machine eligibility constraints, parallel machines in bunching, spool weight and type. Tests about the heuristic are performed with the real production data of a wire production company. Possible further studies are also mentioned in the conclusion section. ····· 10361102296

Based on the results, it was found that in soils comprised mainly of kaolinite mineral, clay alumina was more liable to dissolution and therefore, aluminate hydrate compounds were more likely to be formed in a low and high pH environment. Nonetheless, the coating action of iron oxides was believed to have a detrimental effect on the progression of pozzolanic reactions in lime treated iron-rich kaolinitic soils. This book, therefore, suggests the most significant processes that take part in the formation of cementitious products in chemically treated soils and should be useful for geotechnical engineers and researchers who are interested in understanding the soil-stabilizer interaction at the particle-level. ····· 10361102053

Evolutionary Computing (EC) is proven to be well suited to solve search problems, especially optimization tasks. However, despite the advantages and increasing popularity, there are numerous open questions related to the design and parameter tuning of these algorithms. To answer these questions the author of this book introduces neutral evolutionary search achieved by objective function transformation(s) resulting several advantageous features: (a) Simplifies the design of an evolutionary solver by giving population sizing principles and directions to choose the right selection operator. (b) No parameter tuning required to adjust a solver for different environments, introducing robustness. (c) The applied technique is simple and computationally cheap. (d) It boosts the performance of an evolutionary algorithm on high dimensional (constrained and unconstrained) problems. The analysis throughout this book processes an interesting idea which can be useful for those who wish to apply EC to problem solving: specialists, researchers, lecturers, graduate and undergraduate students. ····· 10361101993· 1 · ::::: · 16 ·· 17 ·· 18 ·· 19 ·· 20 ·· 21 ·· 22 · ::::: · 47 ·
