The trade-off between throughput and memory constraints is a common design problem in embedded systems, and especially for streaming applications, where the memory in question usually occurs in the form of buffers for streams of data. This paper presents a methodology, based on the post-processing of dataflow execution traces, that enables designers to make principled choices in the design space f

The sound transmission in double walls at low frequencies is studied using a detailed geometric model, based on FEM. The model simulates the experiments carried out to determine the sound reduction index of the wall. The wall properties effect on the sound transmission loss is investigated and also how the sound reduction is affected by the dimensions of the connecting rooms.

Popular Abstract in Swedish Fall och frakturer hos äldre är ett vanligt förekommande och ökande hälsoproblem, som orsakar fysiska, sociala och psykologiska problem hos den enskilde och är kostsamt för samhället. Syftet med avhandlingen är att undersöka fallolyckor bland de patienter i åldern 65-74 år som kommit till ortopedklinikens akutmottagning, att undersöka reliabiliteten beträffande gångtestFalls and fractures in older people are a common and increasing health problem which causes physical, social and psychological problems for the individual and is costly to society. The aims of this thesis were to investigate accidental falls of patients aged 65 - 74 who attended an orthopedic emergency ward, to investigate reliability of the modified figure of eight (MFE) and compare it with other

Inscriptions, i.e. the result of how users write, draw, sketch, model or paint or otherwise create persistent content are an important object of study in interaction design. It is conceptualized in many different ways – as representation, externalization, reification, notation, articulation, to name a few, and the resulting conceptual plethora creates problems for advancing scientific understandin

An open European market for goods and services, including transport services, stimulates trade, global competitiveness and economic growth. At the same time, concerns about domestic job security and the environment have sparked debate. This report should be considered a first modest contribution to a mainly unexplored area in the past. Cabotagestudien consists of a walkthrough of previous research

A cultivation strategy combining the advantages of temperature limitedfed-batch and probing control is presented.This is a suitable way to produce recombinant proteins while minimizing therelease of endotoxins which complicates the downstream processing.The downside with the temperature limited fed-batch technique has been the difficulty to achieve a controlled excess of glucose inthe reactor with

Female moths emit sex pheromones to lure a mate. In this thesis I examined the transcriptomes of female moth pheromone glands in order to identify genes encoding proteins involved in pheromone production. Two cDNA-libraries were constructed from Agrotis segetum (Noctuidae) pheromone glands and the remaining body tissue, respectively. The libraries were sampled and sequenced. A total of 707 unigene

This literature survey aims at representing the current research on the cognitive aspects of the design activity, with an emphasis on problem-solving processes. The study is based on the selection of about sixty papers and books on the subject. The principal parameters of the study were defined as follows: general topics of the works, objects of the works, cognitive approaches, research results, s

Policies based upon Extended Producer Responsibility (EPR) aim to reduce the environmental impacts of products by inducing design changes, by way of an extension of producer’s responsibility. Since the early 1990s, a number of countries have EPR-based policies related to end-of-life management of selected product groups. The incorporation of incentive mechanisms for design change in an EPR program

In this paper it is shown that the central features of systematic engineering design process models: a step-by-step concretisation of the product with a systematic variation of subsolutions and recombination are not absolutely necessary. Current models are neither generic nor ideal. Instead of using product characteristics as a basis for design process models, the focus should be on the concrete g

Many large companies, from the traditionally proprietary software industry, are opening up and embracing the open source software (OSS) development process model as a part of their business strategy. Despite the recognized potential the OSS community offers, there are still many questions and unknowns about the transition process. We present an extensive analysis of static software quality metric
