Parallel architectures are essential in order to take advantage of the parallelism inherent in streaming applications. One particular branch of these employ hardware SIMD pipelines. In this paper, we analyse several scheduling techniques, namely ad hoc overlapped execution, modulo scheduling and modulo scheduling with unrolling, all of which aim to efficiently utilize the special architecture desi
The purpose of this study is to describe and analyse changes in the pledge element of the ordination in the Church of Sweden. The transition in 1893 from a clerical oath to an affirmation will be particularly in focus and its causes and effects identified. My intention is thus to contribute to the history of the Swedish clerical oath, describing its complexity and multifarious range of meaning. In
Context: Evidence-based software engineering (EBSE) provides a process for solving practical problems based on a rigorous research approach. The primary focus so far was on mapping and aggregating evidence through systematic reviews. Objectives: We extend existing work on evidence-based software engineering by using the EBSE process in an industrial case to help an organization to improve its auto
We present a digital solution for the front-end electronics of high resolution calorimeters at future colliders. It is based on analogue signal compression, high speed A/D converters, a fully programmable pipeline and a digital signal processing (DSP) chain with local intelligence and system supervision. This digital solution is aimed at providing maximal front-end processing power by performing w
The Bit Flipping algorithm is a hard decision decoding algorithm originally designed by Gallager in 1962 to decode Low Density Parity Check Codes (LDPC). It has recently proved to be much more versatile, for Moderate Parity Check Codes (MDPC) or Euclidean metric. We further demonstrate its power by proposing a noisy Euclidean version of it. This tweak allows to construct a lattice based key exchan
Aims. We study the origin of tail-like structures recently detected around the disk of SU Aurigae and several FU Orionis-type stars. Methods. Dynamic protostellar disks featuring ejections of gaseous clumps and quiescent protoplanetary disks experiencing a close encounter with an intruder star were modeled using the numerical hydrodynamics code FEOSAD. Both the gas and dust dynamics were taken int
We have modified the Erlang runtime to add support for a tracing just-in-time (JIT) compiler, similar to Mozilla’s TraceMonkey. Tracing is a technique to augment an existing interpreter with a JIT simply by recording the instructions executed during a loop iteration, and then generate optimized native code from this. Tracing compilers are particularly suited to optimize number crunching tight loo
The thesis is an extension of an existing authentication service provided by the companies Crunchfish AB and Ubiqo security AB. The authentication service is based on a personal mobile phone and it’s internet connection to verify his/her identity on internet. The companies are interested in expanding the service so that authentication can be done through the mobile phone’s GSM network. This thesis
Popular Abstract in Swedish Förmågan att kunna hitta mat är väldigt viktigt för alla djur eftersom detta påverkar flera saker, t ex hur snabbt man växer. Det i sin tur påverkar vilken roll man har i en grupp, hur mycket energi man har råd att lägga på fortplantning och hur många ungar man får. Att söka mat är oftast för-knippat med att äta, men inkluderar även andra aspekter som att söka efter matThe foraging ability of an organism is essential since it affects various traits, e.g. growth, reproduction effort, social status and, ultimately, fitness. Foraging is often associated with food intake but includes more aspects such as searching for and assessing food patches and evaluating the patch as good or bad compared to the rest of the environment. On top of that, a forager also has to surv
Nine participants, representing eight different Swedish fire consultancy firms participated in a Round Robin study where two different fire scenarios were simulated with the Fire Dynamics Simulator. The participants were given clear instructions on the building layout and heat release rate for the two scenarios. Still, the results demonstrate a significant variation in time to sprinkler system act
Purpose – The purpose of this paper is to study a class of issues that in spite of recognised needs and explicit managerial demands have proven hard to have “stick” in organisations (information security is used as an example). It offers a theory-driven rationale why superficially different issue areas can indeed be considered as instances of the identified class, and builds on complexity leadershPurposeThe purpose of this paper is to study a class of issues that in spite of recognised needs and explicit managerial demands have proven hard to have “stick” in organisations (information security is used as an example).

I denna uppsats kommer jag att försöka förklara vilka faktorer som spelar in i de situationer då en misstänkt säger sig vara skyldig till ett brott som han eller hon inte har begått. Jag kommer även att försöka förklara vilka rättsliga säkerhetsåtgärder det finns som bl.a. kan leda till en minskad risk för falska bekännelser. Detta görs genom en tvärvetenskaplig studie av fenomenet där de juridiskIn this essay I aim to explain what factors that takes part in situations where a suspect admits to a crime that he or she has not committed. I will also try to explain what legal safetynets are in place in order to mitigate the risk of false confessions happening. This is done through an inter-disciplinary study of the phenomena where the legal aspects are complimented by various psycological asp
In this study, different membranes were tested for their use in a vanadium redox flow battery (VRB). The membranes were first tested under charge-discharge operation of the VRB over four charge-discharge cycles at different current densities (20 mAcm-2, 40 mA cm-2 and 60 mAcm-2) and the corresponding cell performance was evaluated in terms of total energy efficiency (EE), coulombic efficiency (CE)
Vid brott med kopplingar till lokala kriminella nätverk är svårigheten att få individer att vittna påtaglig. Åtskilliga individer väljer att förhålla sig passiva och tysta mot rättsväsendet, vilket leder till få uppklarade brott. Vad gäller individer inom nätverken beror tystnaden primärt på faktorer som enskilt gynnande av brottslighet samt inställningen mot rättsväsendet. Hos individer som inte When criminal groups based in socially disadvantaged areas commit crime, there is shown a noticeable difficulty in obtaining witnesses, which leads to few solved cases. Reasons why individuals active in the networks choose to remain silent towards the judicial system depend on factors such as their individual benefits of crime in conjunction with their approach towards the legal system. What conce

In recent years, microwave applications in the food products have attracted increasing attention by the food packaging industry and the consumers due to their convenience, low energy and water usage and short processing time giving them a sustainable advantage over competing technologies. In-pack pasteurization represents one of the fastest developing technologies in preparing and delivering safe
Today, most software systems are event-driven, meaning that code execution is triggered by events handled dynamically. A typical example is a graphical user interface, where a button click initiates a specific action. In contrast, classic automation systems rely on programmable logic controllers, which execute code periodically at fixed intervals. The purpose of this study is to compare periodic a
