Abstract As custom multicore architectures become more and more common for DSP applications, instruction selection and scheduling for such applications and architectures become important topics. In this paper, we explore the effects of defining the problem of finding an optimal instruction selection and scheduling as a constraint satisfaction problem (CSP). We incorporate methods based on sub-grap

Powder Bed Fusion (PBF) is a range of advanced manufacturing technologies that can fabricate three-dimensional assets directly from CAD data, on a successive layer-by-layer strategy by using thermal energy, typically from a laser source, to irradiate and fuse particles within a powder bed.The aim of this paper was to investigate the application of this advanced manufacturing technique to process c
The global environment suffers from utilizing fossil fuels to powering internal combustion engines (ICE), due to the massive amounts of released CO2. Besides the global impact, the local environments experience high concentrations of harmful pollutants such as NOx, CO, soot and particulate matter (PM). The automotive industry is continuously striving to find new solutions to decrease fuel consumpt
This study explores the experiences and reflections of staff in intellectual disability (ID) services concerning ageing with ID. Qualitative interviews were conducted with 24 staff members in group homes and daily activity centres. The findings showed that the staff were uncertain about the signs of ageing in people with intellectual disabilities; they compared the life conditions of these people
On 26 May 2016 the Court of Justice of the EU (CJEU) decided Bookit Ltd v HMRC (Bookit)1 which dealt with the interpretation of the exemption for transactions concerning payments within article 135(1)(d) of the Council Directive on the common system of value added tax (the VAT Directive).2 Article 135(1)(d) of the VAT Directive provides that Member States shall exempt "transactions, including nego
Objectives Preventing adverse events (AEs) after orthopaedic surgery is a field with great room for improvement. A Swedish instrument for measuring AEs after hip arthroplasty based on administrative data from the national patient register is used by both the Swedish Hip Arthroplasty Register and the Swedish Association of Local Authorities and Regions. It has never been validated and its accuracy
An ECG risk-score has been described that predicts high risk of subsequent cardiac arrest in young patients with hypertrophic cardiomyopathy (HCM). Myocardial fibrosis measured by cardiac magnetic resonance (CMR) late gadolinium enhancement (LGE) also affects prognosis. We assessed whether an ECG risk-score could be used as an indicator of myocardial fibrosis or perfusion deficit on CMR in HCM. In
Isoprene is a highly reactive volatile organic compound emitted by vegetation, known to be a precursor of secondary organic aerosols and to enhance tropospheric ozone formation under polluted conditions. Isoprene emissions respond strongly to changes in meteorological parameters such as temperature and solar radiation. In addition, the increasing CO2 concentration has a dual effect, as it causes b
Spatially coupled turbo-like codes (SC-TCs) have been shown to have excellent decoding thresholds due to the threshold saturation effect. Furthermore, even for moderate block lengths, the simulation results demonstrate a very good bit error rate performance in the waterfall region. In this paper, we discuss the effect of spatial coupling on the performance of TCs in the finite block-length regime.
The interest for the design of life environments for persons with dementia is growing stronger among architects, engineers, social scientists and those responsible for housing and health care planning. This development is connected to the enlarged group of people that become afflicted by this disease and to the fact that a safe environment is proved to be very important for their well-being as wel
This Ph.D. submission deals with contemporary demonstration culture and political activism, seen as performance through performance. It consists of both a practical and a theoretical part. These are intertwined on various levels of the project. My submission, however, is made up of the two following parts: 1: A textual part, divided into 8 parts. Each part contains a script, an analysis and a nu
A widely embraced approach to mitigate the dynamic degradation in low-inertia power systems is to mimic generation response using grid-connected inverters to restore the stiffness of the grid. In this article, we seek to challenge this approach and advocate for a principled design based on a systematic analysis of the performance trade-offs of inverter-based frequency control. With this aim, we pe

By selecting three municipalities at varying stages of digitalization, the study highlights differences in the descriptions of the relationship between social workers and clients, shedding light on whether, and if so, how, digital tools influence this relationship.
Argonauts of industry: Knowledge gathering and technologies in use in Sweden’s industrial breakthroughIn this article we explore how knowledge transfer about industrial production and new technologies affected Sweden’s rapid industrialisation in the second half of the nineteenth century. Focusing on two case studies taken from the Swedish glass and gunpowder industries, we argue for the importanceArgonauts of industry: Knowledge gathering and technologies in use in Sweden’s industrial breakthroughIn this article we explore how knowledge transfer about industrial production and new technologies affected Sweden’s rapid industrialisation in the second half of the nineteenth century.

Methanol (CH3OH) is an attractive alternative fuel that can reduce net carbon release and decrease pollutant emissions. In this study, methanol and n-dodecane spray flames were investigated using Large-Eddy Simulation (LES) and direct coupling with finite-rate chemistry. The selected ambient conditions are relevant to engines and were previously unreported for numerical methanol spray studies, i.e
Instruction scheduling is one of the most important optimisations performed when producing code in a compiler. The problem consists of finding a minimum length schedule subject to latency and different resource constraints. This is a hard problem, classically approached by heuristic algorithms. In the last decade, research interest has shifted from heuristic to potentially optimal methods. When us
Sverige har sedan länge ansetts vara ett land befriat från svågerpolitik och korruption. Korruption är dock ett vitt begrepp som härstammar från det latinska ordet corrumpere, vilket betyder muta. Följaktligen omfattas den straffrättsliga terminologin av givande och tagande av muta av begreppet korruption. Korruption anses vara ett medel för att otillbörligen påverka besluts- och handlingsprocesseSweden has long been considered a country free from nepotism and corruption. Corruption is however a broad term which derives from the Latin word corrumpere, meaning bribe. Consequently the criminal terminology of giving and receiving bribes comprises the concept of corruption. Corruption is a way to improperly influence the decision making and processes in a society. The damaging effects on a soc
Monarchy was the dominant form of rule in the pre-modern era and it persists in a handful of countries. We propose a unified theoretical explanation for its rise and decline. Specifically, we argue that monarchy offers an efficient solution to the primordial problem of order where societies are large and citizens isolated from each other and hence have difficulty coordinating. Its efficiency is ch
