This Master Thesis report describes the development of a new surveillance camera design containing PIR-sensors (Pyroelectric Infrared). The background to this project lies in the idea that PIR-sensors and video-motion detection technology can complement each other and thereby reduce false alarms. Research on PIR-sensors and optics were carried out to gain and understanding of the limitations and p
Library 2.0 is a term which emerged a few years ago and is frequently discussed. There is no uniform definition of the term but the central aspect of the concept is to encourage increased participation from library users. The aim of this Master's thesis is to investigate if and if so, how the professional role of the librarian is affected by Library 2.0. To do that, we have conducted a case s
The Sri Lankan Tamils have been a part of complex history within Sri Lanka in regard to their ethnic Identity, which is mostly associated with the civil war that went on for almost 30 years. More than a decade after the end of the conflict, this thesis work analyzed how todays Jaffna Tamils view their own identity in Colombo. As a cosmopolitan melting pot, it brings in different groups and culture
Fram till för några decennier sedan, innan ordförande Maos död, var Kina avstängt från resten av världen. Idag är Kina världens näst största ekonomi och en mycket attraktiv destination för utländska investeringar. Medan denna ekonomiska explosion har medfört enorm teknikutveckling för Kina, har vissa observatörer påstått att dessa framsteg har kommit genom det som kallas "tvångsöverföring av Up until a few decades ago, before the death of Chairman Mao, China was closed off from the rest of the world. Today, China is the second largest economy in the world and a very attractive destination for foreign investment. While this economic explosion has brought with it tremendous advancement in technology for China, some observers have alleged that these advancements have come through what is
The demand for higher education is quickly rising in the Sub-Saharan Africa region and the question of giving access to all members of society often comes down to financing. Many countries, including Tanzania, have opted for cost-sharing policies where the cost of education is split between the state and the individuals - leaving many without the possibility of attending higher education. This mas
This thesis examines a local low-carbon energy transition in an urban context with regard to energy justice. It takes the Vauban district in Freiburg (Germany) as a case study which has been described as a successful case of energy transition and a model for sustainable urban development. From a theoretical point of view, energy justice encompasses a fair distribution of costs and benefits of an e
Safety is intertwined with learning, without learning safety would be a static construct. To advance, safety concepts and theories all rely on the art of processing knowledge and though learning attaining a contributing effect. In shipping, the abstract of a near-miss is promoted as ‘good business and economic sense because it can improve crew performance and reduce costs’. Studies have shown th
The objective of this thesis was the impact evaluation of several parameters affecting daylight conditions in a typical cellular office in Lund, Sweden. The research approach that was followed consisted of three distinct steps; the literature review in order to specify the dependent and independent variables of the study, the simulation part to produce daylight performance data and the graphical a
It has been proven that music education can have many benefits to the development of children. It can improve communication, reasoning, memory, coordination, spatial intelligence and mathematical skills as well as enhancing emotional and intellectual development. The current market provides a broad range of instruments and professional devices, but it lacks creative tools useful to educate in musi
The DARPA Grand Challenge (DGC) 2005 was a competition, in form of a desert race for autonomous ground vehicles, arranged by the U.S. Defense Advanced Research Project Agency (DARPA). The purpose was to encourage research and development of related technology. The objective of the race was to track a distance of 131.6 miles in less than 10 hours without any human interaction. Only public GPS signa
The report discusses mathematical modeling of thermal components, such as heat exchangers and control valves. A flexible model library for simulation has been developed. The object-oriented and equation-based modeling language Omola is used to describe the components in mathematical terms. The library of models can be used to build models of more complex thermal systems, such as heat exchanger uni
A cohouse is a house with private apartments as well as shared areas and they can be organized in different ways. The purpose of the project was to learn more about cohousing. How the common rooms are used and what kind of furniture is preferred. My method was to read about the topic and then visit cohouses in Sweden and Germany to do interviews and study the use and function of the sha
Background: Life near death is difficult foremost for the patient but also for people around the dying person. Purpose: The purpose of this essay is to investigate palliative-care patients´ psychological and religious approaches and how they cope with their situation that they are dying by interviews of chaplains, pastors, priests and personnel working with dying persons at hospice. Material and m
Mantle cell lymphoma (MCL) is a rare, often aggressive type of B-cell lymphoma with poor survival and no cure. Cancer and cancer treatment has a negative impact on health-related quality of life (HRQOL) both during active disease and in the long term, and improvement of HRQOL is a crucial objective of cancer therapy in older patients and no curative intent. Baseline HRQOL has in other lymphoma pop
A flow injection thermal microbiosensor was designed for the simultaneous determination of multiple analytes. The biosensor consisted of five thin-film thermistors which were located along a single microchannel. The device was fabricated on a quartz chip by micromachining. The feasibility of employing this system for the detection of two independent enzyme reactions was demonstrated using two diff
Floral scent is an important mediator of plant–pollinator interactions. Multiple recent studies report ample intraspecific scent variation among populations and individuals. Yet, few studies have eastimated effects of phenotypic plasticity on floral scent in response to differing environmental factors. In this study, we investigated the effects of nutrient and water availability on floral scent in
Objective: A new European Union (EU) regulation for safety barriers, which is based on performance, has encouraged road agencies to perform an upgrade of old barriers, with the expectation that there will be safety benefits at the retrofitted sites. The new class of barriers was designed and installed in compliance with the 1998 (European Norm) EN 1317 standards for road restraint systems, which l
To avoid being detected by radar, it is necessary to reduce stealthy military platforms' radar cross section (RCS). The operation of overlaying the metasurface (MS) on the targets is a good solution. A simple chessboard MS structure that can achieve low RCS over a large bandwidth is proposed. Only one unit cell is used to construct the MS. First, the unit cell working in 0.5 and 1−λ modes is desig
Cities are growing in size and becoming increasingly dense. This situation calls for strategic planning of green infrastructure in the urban planning process. Safeguarding the green infrastructure is important for maintaining urban ecosystem services and increasing the well-being of urban populations. To facilitate appropriate urban planning that enables cities to grow sustainably, it is important
Purpose: The postponement principle concerns defining when and where value is added, usually referring to hardware components for physical products. However, in modern supply chains, software’s importance is increasing, impacting the timing and location of value-adding operations. Lacking insights into software-driven implications for postponement, we aim at elaborating on the postponement princip
