The heat conduction in a two-dimensional square plate at nano/micro scales is investigated using numerical and semi-analytical methodologies which are energy conserving dissipative particle dynamics (DPDe) and Boltzmann transport equation (BTE) with the gray relaxation time approximation. The solution domain was considered to be a two-dimensional square plate surrounded by walls having constant te
Full-scale ethanol production from spruce has been evaluated, mainly from an energy perspective, using an Aspen Plus-model including all major process steps. The model input was based on data recently obtained on lab scale or in a process development unit. A number of different process configurations are presented in order to demonstrate how heat integration within the ethanol process significantl
This compilation should be viewed as a kind of prolegomena to a history of interpolation. Three letters from Mischa Cotlar, Antoni Zygmund and Olof Thorin from c. 1980 are reproduced. Thorin's letter is given in translation. These letters were written as a reply to an inquiry by the editor/translator. It is remarkable that while Thorin spent his whole professional life as an actuary, neither of hi
This article problematizes piracy a) as a hegemonic discourse and technology of control, aiming to securitize late capitalist accumulation; b) as a practice developed by the multitudes that is compatible to post–Fordist mode of production and to neoliberal norms; and, c) as resistance to dominant mode of late capitalist production, distribution and consumption of immaterial goods. The article addr
Ever since the release of the Kyoto protocol the demand for CO2-free processes have been increasing. In this paper three different concepts with no or a very small release of CO2 to the atmosphere are evaluated and compared concerning plant efficiency and investment cost. A novel approach to biomass gasification is proposed to provide fuel for a combined gas turbine cycle, where the bio
The introduction of guard channels in a cellular network is a method for giving priority to on-going calls by having channels exclusively reserved for handover purposes. Herein, an adaptive measurement-based dynamic guard channel scheme is introduced. The proposed scheme uses the number of on-going calls in adjacent cells and measurements of handover probabilities to determine the amount of guard
Packaging has a significant impact on the efficiency of logistical systems and therefore, improvements in the retail supply chain can be achieved through the integration and development of the systems of packaging and logistics. In order to enable these improvements, models are needed that facilitate evaluations along the supply chain in order to grasp the whole picture and avoid sub-optimisations
Ethnic discrimination, like most other socially pathological practices, does not yield itself easily to legal regulation. On the one hand, it is often difficult to amass evidence and present proof of the unlawful nature of many practices, which are experienced as discriminatory by some citizens. On the other hand, the law is far from the exact, logically coherent, impartial, independent, and effec
In this paper the problems of organization and representation of concept knowledge are addressed from an autonomous agent perspective. The first part of the paper discusses the question of why an autonomous agent needs concepts at all and what other uses it can make of them. After the necessary and/or desirable functions of concepts have been identified, previous attempts to represent concepts are
The existing research has produced a useful palette of ideas that help us make sense of the phenomenon of organizational control. But there is a trend that hampers the interpretative possibilities: a heavy bias towards vertical forms of control. It is frequently assumed that the control that operates in organizations has its origin in the actions of managers. This assumption is especially problema
Hydrogeological and geophysical methods were applied in the Río Artiguas watershed, a mountain basin located in central Nicaragua. This area is under environmental stress from anthropogenic activities like gold mining using mercury and waste disposal into the streams. The aim of this work was to characterise the hydrogeological conditions in the basin with emphasis on understanding the possible co
