Collection attributes, as defined by Boyland, can be used as a mechanism for concisely specifying cross-reference-like properties such as callee sets, subclass sets, and sets of variable uses. We have implemented collection attributes in our declarative meta programming system JastAdd, and used them for a variety of applications including devirtualization analysis, metrics, and flow analysis. We p
Many applications in telecommunications will depend on distributed systems to provide enough capacity. In a distributed system a service is split up into a number of modules (often called objects) that can be placed at different nodes or processors in a network. A service can be seen as a number of invocations of the objects in a certain order. There are a number of performance problems which have
Studies on shading behaviour of contractors have in the past been focused on lack of product quality and other factors affecting the customer. This study of 222 publicly procured road and railroad projects aim to analyse shading behaviour from a perspective of workers safety. The study shows, though with limitations in statistical power, that the number of reported incidents related to workers’ sa
The instrument DREAM, in construction at the long pulse European Spallation Source (ESS), is a new type of neutron time-of-flight powder diffractometer, which utilizes additional choppers to meet the typical high resolution requests. Pulses will be of symmetric shape and their width can be varied from 10 μs to 1 ms, providing an unprecedented flexibility from highest to low resolution with optimiz
Every year there are thousands of pedestrians in Sweden who are injured because of slippery pavements and roadways. Using an appropriate anti-skid device may reduce the risk of slips and falls on ice and snow. Methods to describe functional problems in walking on different slippery surfaces during winter have been developed as rating scales for evaluating walking safety and walking balance and an
In massive MIMO performance evaluations it is often assumed that the terminal has a single antenna. The combination of multiple antennas in a terminal and massive MIMO precoding at the base station side can further improve overall system performance. We present measurement results for multi antenna terminals operating in different transmission schemes and how they perform under varying loading con
We demonstrate for the first time a technology which allows the monolithic integration of both p-Type (InAs-Si) and n-Type (InAs-GaSb) heterojunction Tunnel FETs (TFET) laterally on a Si substrate. The lateral heterojunction nanowire (NW) structures are implemented using top-down CMOS-compatible processes combined with Template-Assisted Selective Epitaxy (TASE) [1] of the III-V materials. Sub-40nm
We have experimented with different neural network based architectures for bio-inspired self-organizing texture and hardness perception systems. To this end we have developed a microphone based texture sensor and a hardnesssensor that measures the compression of the material at a constant pressure.We have implemented and successfully tested both monomodal systems for texture and hardness perceptio
In this thesis, the power dynamics underpinning the relationship between USAIDfunded humanitarian organizations and U.S governmental agencies – in relation to the Global War on Terror (GWoT) - are critically investigated. To this end, a Foucauldian lens of ’disciplinary power’ is utilized to uncover U.S governmental agencies’ employment of disciplinary practices categorized as surveillance, correc
Machine learning projects are often constrained by data that is messy, scarce, sensitive or costly to produce. These are issues which could be mitigated by synthetic data. This thesis tries to improve Swedish license plate localization in images by synthesizing images through superimposition, a process that produces data cheaply and in abundance. A generative process algorithmically creates imag
Rätten till abort är idag ett aktuellt ämne som är föremål för mycket debatt runt om i världen. I Sverige har vi idag fri aborträtt, förutsatt att graviditeten inte är för långt gången, men så har det inte alltid varit. Den här uppsatsen undersöker den svenska abortlagstiftningen ur ett rättsutvecklingsperspektiv med utgångspunkt i lagförarbeten och lagtext. Fokus för uppsatsen ligger på hur abortThe right to abortion is a current issue which is widely debated around the world. The current abortion law in Sweden states that the choice of an abortion is entirely up to the woman. This is an essay about the history of the Swedish abortion laws from a legal development perspective. The material that the essay is based on is mainly abortion legislation and legislative history. The focus of the
Despite ample evidence on the importance of labor market opportunities for women’s bargaining power, the link between public childcare availability and female empowerment has so far been widely overlooked. Using detailed survey data on household dynamics, this paper investigates the impact of the Mexican childcare program Estancias Infantiles para Apoyar a Madres Trabajadoras on women’s decision-m
In this thesis I examine how two variables: closeness and the TP-share (two-party-share) of votes impact turnout in elections. I use data from the 2016 Georgian parliamentary election and its two-rounds of election in the majoritarian districts. This field of research poses a wide variety of methodological approaches. One concerns the definition of the dependent variable, turnout. Instead of only
In his original contribution, Exner's principal concern was a comparison between the properties of different aftereffects, and particularly to determine whether aftereffects of motion were similar to those of color and whether they could be encompassed within a unified physiological framework. Despite the fact that he was unable to answer his main question, there are some excellent-so far unknown-
In the paper we consider a commonly known network design problem with demand restoration assuming stub release. No compact linear programming (LP) formulation for the problem is known, and all known non-compact LP formulations of the problem require NP-hard path generation (pricing). Therefore, the problem itself is suspected to be NP-hard - this, however, is not actually known. The main result of
In this study four different types of PIR materials have been tested to examine the possibility to use the cone calorimeter (ISO 5660) as a screening tool to evaluate the fire properties of the insulation. As such, manufacturers can be able to make a quick control of the insulation without having to spend resources on full scale testing. One of the materials was from an FM-approved (standard 4880)
