In this short note, we argue that performance per watt, which is often cited in the graphics hardware industry, is not a particularly useful unit for power efficiency in scientific and engineering discussions. We argue that joules per task and watts are more reasonable units. We show a concrete example where nanojoules per pixel is much more intuitive, easier to compute aggregate statistics from,
En analys av komediserien Seinfeld där jag söker efter postmoderna tendenser i handling, manus och karaktärer för att besvara min frågeställning: Vad är identitet enligt Seinfeld som TV-serie?
Right-wingauthoritarianism (RWA) is regularly implicated as a potential risk factor of abusive behavior, whereas social dominance orientation (SDO) is not. We compared RWA and the two subscales of SDO, SDO-Dominance and SDO-Egalitarianism, as factors behind legitimization and hypothetical self-involvement in the use of torture-like abusive behavior (a scenario from Abu-Ghraib military prison). Int
The objective of this study has been to analyze the introduction and development of mineral wool building insulation in Germany, Sweden and the UK, and to examine the policy instruments that support these processes. The aim has been to improve our understanding of the role of the policy instruments. The analysis focuses on the development of the policy framework, the development of technology, the
Photovoltaic modules in two-dimensional low-concentrating systems with specular parabolic reflectors often experience high local irradiance that causes high local currents and cell temperatures. This generally results in power losses. The use of low-angle scattering reflectors gives a smoother irradiance distribution, which results in a higher fill factor. In order to study how the choice of refle
Glucose-evoked insulin secretion exhibits a biphasic time course and is associated with accelerated intracellular granule movement. We combined live confocal imaging of EGFP-labelled insulin granules with capacitance measurements of exocytosis in clonal INS-1 cells to explore the relation between distinct random and directed modes of insulin granule movement, as well as exocytotic capacity. Reduci
The need for low-carbon transitions in the industrial sector is increasingly recognised by governments and industry. However, radical pathways for reaching near-zero emissions in the energy intensive basic materials industry are still relatively unexplored. Most studies focus on mitigation options that lead to marginal emission reductions, e.g., energy and materials efficiency improvements and som
This paper examines Sweden’s role as a pioneer in mitigating climate change. Critical discourse analysis of climate and energy policy unveils Sweden’s ambition to ‘lead-by-example’, by virtue of a win-win combination of economy and environment via stringent regulations and an early-mover strategy on eco-innovations. The extent of the unilateral approach is constrained by concerns for the competiti
This paper expands Ghaddar et al. [N. Ghaddar, K. Ghali, R. Saadeh, A. Keblawi, Design charts for combined chilled ceiling displacement ventilation system (1438-RP), ASHRAE Transactions, 143 (2) (2008) 574-587] design charts of combined chilled ceiling (CC) displacement ventilation (DV) system to operating sensible load ranges from 40 W/m(2) to 100 W/m(2). It develops a global correlation of syste
Abstract in UndeterminedEconomic development that includes investments in infrastructure and buildings requires energy intensive basic materials such as steel and cement. The production capacity of these industries is also growing most rapidly in developing countries [WEC, 1995 #41]. Energy intensive industries typically account for a relatively small share of the value-added in industry but a rel
Offspring sex ratios may deviate from parity when the fitness benefits of producing male or female offspring vary. We tested for sex ratio bias in smooth-billed anis Crotophaga ani, a communal laying cuckoo with low within-group relatedness and high offspring dispersal. One male group member performs nocturnal incubation and sires more offspring than other males in the group, suggesting males may
Eyestrain is a common issue when performing visually demanding work, often accompanied by neck and shoulder strain, as well as visual problems such as dim vision. The aim of this paper is to investigate the association between eyestrain and musculoskeletal strain, as well as the association between eyestrain and visual symptoms. Two regression analyses were conducted on subjective ratings of eyest
Our society is moving towards renewable resources, where biomass, rich incarbohydrates, is producing chemicals and fuel. However, there are severallimitations when it comes to valorisation of the carbohydrates from renewablebiomass. One major hurdle is the over-functional nature of carbohydrates, making them difficult to process by conventional chemistry. Carbohydrate activeenzymes can help overco
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
Through a systematic review this study critically examines existing peer-reviewed evidence on the often-overlooked gender dimensions of the just energy transition. We found 52 peer-review journal papers focusing on three main themes: (1) how energy production can worsen pre-existing gender-based vulnerabilities, (2) how energy consumption can reproduce gender-based energy poverty and (3) how femin
Information system have become exceedingly important in our daily working lives and by that tightly connected with jobs. Job satisfaction is relatively explored research field which has become very popular in the last decades. But how do information systems affect other aspects of work, and how does our perception of our working life affect our acceptance of information systems is relatively unexp
