This paper describes a model for mobile radio channels that includes consideration of directions of arrival and is thus suitable for simulations of the performance of wireless systems that use smart antennas. The model is specified for 13 different types of environments, covering macro- micro- and picocells. In this paper, a hierarchy of modeling concepts is described, as well as implementation as

Background: There is an internal belief within Axis that despite their products’ relatively high initial price, the total cost of ownership (TCO) of an Axis camera solution is lower than that of other brands. However, there is no internal research or tools to verify if it is true. Without this, Axis is unable to communicate their belief in an educated and quantifiable way, which is desired in

The He-3 “crisis” has become a fact in the last decade and large scale neutron detectors based on He-3 technologies have become unaffordable. This new He-3 reality has resulted in a major effort worldwide to develop replacement neutron-detector technologies. Many of these technologies are in their infancy and need to be thoroughly tested before becoming mainstream, while others are approaching co

Equity is an important policy objective in the health care field. The importance of equity in health care provision can be argued from various points of view. As a result governments in all countries attempt to provide health care systems that enable equal access for everyone. Zambia is no exception. In the health care reforms the objective of the national health strategy is to provide Zambians wi

Electric Road Systems (ERS) have emerged as an alternative to deal with the main drawbacks that battery electric vehicles present (i.e., higher cost, short driving range, long charging times, etc.). This paper analyses the societal cost of electrifying all road transport in Denmark under four different scenarios. The first scenario considered in this study is based on todays approach of having ele

As massive MIMO is currently considered a leading 5G technology candidate, channel models that capture important massive MIMO channel characteristics are urgently needed. In this paper we present an attempt for massive MIMO channel modeling based on measurement campaigns at 2.6 GHz in both outdoor and indoor environments, using physically-large arrays and with closely-spaced users. The COST 2100 M

Background and aims: As part of an RCT in six European sites, the direct mental health care cost for 422 patients with schizophrenia was analysed according to how total and medication costs differed across sites and which variables were likely to predict total or service-specific costs. Method: Service use was recorded continuously during a 12-month follow-up. Prescribed psychotropic medication wa

Purpose: The aim with the report is to investigate if the South East Asian customer on the food processing market base their investments on Total Cost of Ownership and if so, which are the cost drivers considered most vital. Moreover, do these cost-drivers diverge from the perception FP Ltd has, and if so, can a Total Cost of Ownership-model help to achieve a mutual understanding? Methodology: Fir

The aim of this study is to identify what the relationship between ESG scores and capital structure is, and whether it differs depending on the selected capital structure measure. Building on previous literature on sustainability strategies and capital structure, this paper revises the current state of the interconnectivity between ESG and financing decisions. By employing a quantitative study wit

A multidisciplinary study of the implementation potential of a biorefinery, using forestry residues as feedstock, is performed by assessing techno-economic factors, system integration and feedstock supply. The process is based on biochemical conversion of logging residues to produce ethanol, biogas, pellets, heat and electricity. Nine models were designed in Aspen Plus based on the available feeds
