Today, technology is everywhere in our everyday lives whether it is wanted or not. The world has become digitalized and this development continues for each year that passes. The Swedish government has now (2018) updated the curricula for both kindergarten and elementary school to include more digital aspects in the teaching. With this background, this thesis (project) set out to design a digital a
The construction and demolition sector stands for a large amount of the waste produced every year, roughly one third of all waste produced every year in Sweden, comes from this sector. The construction material manu- facturer Ecophon is a world leading company in manufacturing of acoustic products made out of glass wool, which are used in all kind of buildings and the general geometry of an acoust
During the last decades the Swedish Child and Adolescent Psychiatric Services (CAP) has undergone major organizational changes. According to social research the changes are mainly due to new public management reforms. The aim of this study was to examine how social workers, i.e. psychiatry counsellors, experienced and coped with their working conditions within CAP. The method chosen for this study
This study investigates strategies for igniting hydrogen in compression ignition engines, a process traditionally hindered by hydrogen’s high ignition temperature. In conventional dual-fuel engines, a small diesel pilot is often used to ignite hydrogen, taking advantage of diesel’s lower ignition temperature to initiate combustion. While effective, this approach introduces carbon emissions, limiti
Digitalization is transforming the tax landscape, reshaping the operations of tax departments, authorities, and professionals. With rapid digital advancement, there has been a shift toward real-time reporting, e-invoicing, and greater reliance on digital data. This change is driven by investments in data analytics, robotic process automation, cloud platforms, and, more recently, artificial intelli
This paper describes measurements of the transverse momentum spectra of W and Z bosons produced in proton–proton collisions at centre-of-mass energies of s=5.02 TeV and s=13 TeV with the ATLAS experiment at the Large Hadron Collider. Measurements are performed in the electron and muon channels, W→ℓν and Z→ℓℓ (ℓ=e or μ), and for W events further separated by charge. The data were collected in 2017
Hard alumina-based coatings can be applied to cast iron brake discs using a plasma electrolytic aluminating (PEA) process to enhance wear and corrosion resistance and reduce brake particle emissions. This work was first to study the influence of friction wear on corrosion property and then investigate the influence of corrosion on brake particle emissions from cast iron discs through comparison of
There has been a growing interest in how workers in high-carbon industries are impacted by low-carbon transitions and how such transitions can be implemented in a way that is just. This study explores the socio-cultural dimensions of these processes, focusing on the role of identity in shaping workers’ perceptions of low-carbon transitions and their ability to navigate change. It does so through a
An extensive part of the road network in Sweden still consists of gravel roads, but operation and maintenance of these roads is complex due to the Swedish climate and the low traffic volume. This report further examines how operation and maintenance of gravel roads is executed and how it can be done in a cost effective way. In order to do so, the report contains both a literature study and a field
Children today grow up with a plurality of technological opportunities. In the last ten years the digital development has enable multiple possibilities to participate in a so called ‘digitally mediated society’. Ever since the discussions do not stop, in what way do children learn a responsible use of digital media. How do children develop to Digital Citizens in the future? For the investigation o
In applications of real time gesture detection on devices which have cameras and limited power supply it is important to consider both robustness and maintaining a low power consumption. A well explored approach is the use of cascades of boosted classifiers. As retraining is a very cumbersome process, online environment adaption would be an appealing approach to counter situations where the booste
The amount of data produced is growing rapidly and organizations are struggling to make use of the generated data from the vast amount of sources. Analyzing and interpreting data to find patterns and trends has become a competitive advantage for companies working with customer oriented operations. Many previous studies have shown the value potential of working with big data. In order to create val
The purpose of this thesis is to analytically examine and investigate if male and female have no meaning with regards to the County Administrative Courts descriptions and assessments in cases regarding the Care of Abusers (special provision) Act (LVM). It is to investigate if notions of gender are expressed in these LVM-cases, and if so, how are they expressed and how can we understand these expre
Title Identifying critical service issues in the service encounter – a first step in the development of a conceptual for the shipping industry Author Claas Boomgaarden Key Words Service Quality, Service Encounter, SERVQUAL, INDSERV, PDSQ, LSQM, Shipping Industry, Service Science, Service Dominant Logic, Relationship Marketing Purpose The purpose of this research is to provide a first step in th
Background: Many companies are today struggling to keep up with the challenges that have arisen from the increase of globalization and harder competition during the last couple of decades. This might reflect on companies as they need to do a strategic organizational change in order to create or retain a competitive position on the market. Those kind of change projects are usually difficult to
The reality of climate change and the substantial impact it can have on our environment and social systems in the future is globally recognized. Intergovernmental Panel on Climate Change (IPCC) have acknowledged that global warming will lead to higher temperature and less precipitation and that it will have an effect on food safety, especially in developing countries. The aim of this study is to i
Working Capital Management (WCM) is a management tool used in large companies to optimize the use of cash by minimizing the amount of cash tied up in working capital accounts, in order to reduce the risk of insolvency and to increase profitability. One of the main reasons why start-ups fail is related to liquidity issues. Despite a wide acceptance regarding the importance of WCM for start-ups, the
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
Bygg- och anläggningsbranschen är, och kommer fortsatt att vara, en extremt viktig gren av det svenska näringslivet. Av konstanta och beräknade ökningar i befolkningsmängd följer nödvändiga satsningar på bostäder, infrastruktur och industrier. Det är därför av största vikt att den kontroll, alltså besiktning, som sker av byggen utförs enligt kontrakt och avtal samtidigt som denna är smidig, korrekThe construction industry has historically constituted, and will continue to constitute, an important part of the Swedish industry. Projected population increases will require important investments in housing, infrastructure and industry. It is therefore of upmost importance that construction surveying be conducted in an accurate, efficient and timely manner so as not to impede the delivery of the
This thesis aims at comparing the differences between Chinese welfare system and Swedish welfare system in respects of maternity insurance, parental leave and childcare. The reason comparing welfare system in these specific aspects is because they have intense relations with the mothers’ and children’s benefits. They also influence the mothers’ will of pregnancy. Selecting these two countries as t
