This paper presents a new analytical solution for the influence of regional groundwater flow on the performance of borehole heat exchangers. The solution concerns a vertical borehole. The transient thermal response for the fundamental case of a step-change in heat injection rate is given. The solution is remarkably simple and the formulas quite handy considering the complexity of the convective-di

The performance of a turbo code is dependent on two properties of the code: its distance spectrum and its suitability to be iteratively decoded. The performance of iterative decoding depends on the quality of the extrinsic inputs; badly correlated extrinsic inputs can deteriorate the performance. While most turbo coding literature assumes that the extrinsic information is uncorrelated, we investig

Popular Abstract in Swedish Värdebaserad styrning har på senare tid tilldragit sig mycket intresse från såväl akademiker som praktiker. På basis av fallstudiemetod beskrivs, analyseras och konceptualiseras värde¬bas¬erad styrning utifrån ett ekonomistyrningsperspektiv. Medan tidigare forskning har fokuserat på de presstationsmått som lanseras i den normativa litteraturen visar denna avhandling atValue-based management has attracted considerable interest among organizations and academics in recent years. Responding to calls for case-based research, this thesis describes, analyses and conceptualizes value-based management as a management accounting construct. While previous research has focused on the measures (eg. EVA) advanced in the normative literature, this analysis demonstrates that

Models of the engineering design process and of the development process nowadays present similar forms in the engineering design literature and interact in a similar way. These models are often presented as generic, in order to be used in a wide area of applications. This interaction is, however, not unproblematic, and in this publication we present some important issues and challenge the generic

A new parametrization for use in periodic semiempirical quantum-chemical INDO calculations is proposed. Parameter sets for C and N atoms are tested on a number of C- and N-containing molecules, giving reasonably good agreement with experimental data and/or ab initio results. The new parametrization is intended for studies of organic adsorbates on oxide surfaces using a periodic large unit cell (LU

The presented thesis explores role of glial cell line derived neurotrophic factor family receptor a2 (GFRa2), as well as neuropeptide Y (NPY) and galanin and their receptors in modulation of seizure activity. We demonstrate that mice lacking the GFRa2 gene (GFRa2-/-) exhibit suppressed seizure generalization in traditional and rapid kindling models. We suggest that impaired basal excitatory transm

In this chapter two examples are presented were the Swedish legislator built market mecanisms into the unemployment insurance system and the pension system. The two market mecanisms were designed to make trade unions with high unemployment show restraint in collective wage bargaining and to make elderly people chose two postpone retirement. The aim of the legislation was to make the opposite choic

Verksamhetsförlagda praktikperioder används som ett verktyg för att väva samman teoretisk och praktisk utbildning. Boken utforskar förutsättningar för en sådan kunskapsintegration i tre professionsutbildningar: psykolog, socionom och lärare. I en djupdykning i psykologutbildningens praktik beskriver blivande psykologer och handledare sitt lärande. En generell ram som kombinerar vetenskaplig forskn
