Competition on the Swedish grocery retail market has increased profoundly, mainly as a result of foreign retailers entering the market. To keep up with this intensified competition, Swedish retailers need to lower their costs. In May 2004 ten new countries will become members of the EU. The majority of these countries are known for being labor-intensive states and in addition it is inexpensive for
A new type of nanoparticle generator is being developed at Lund University. This project aimed to characterize it in order to produce a stable aerosol for medical inhalation applications. This project characterized size distributions during different parameter settings for the generator. The experimental work included assessing the effect of cleaning the generator between experiments for experimen
This master thesis investigates how to build in a sensitive environment in two senses. Partly, in terms of the physical context; Bovallstrand, a small fishing village in the archipelago of Bohuslän, with strength building restrictions and a present cultural heritage. Further, the chosen site for the project. An unbuilt cape where the nature is growing freely in between rising hills. Where the clif
När en vårdgivare och en vårdtagare saknar ett gemensamt språk att kommunicera på möjliggörs vården först genom översättning av en tolk. För att utforska svenska psykologers erfarenheter av att arbeta med tolk: vilka problem det ger upphov till, om det går att bedriva behandling samt hur de kontextuella faktorerna ser ut på svenska arbetsplatser, gjordes en enkätundersökning. Enkäten besvarades avWhen a clinician and a patient don’t share a language for communication, an interpreter is needed to enable the communication. To explore the experiences of Swedish psychologists of working with a translator a survey were conducted. The aim of the study were to explore which problems arise from working with an interpreter, the possibility of providing psychological treatment and the workplace rout
Skrotning av skepp, även kallat skeppsåtervinning, är en smutsig och farlig industri. Ekonomiska motiv driver skeppsägare att exportera sina icke önskvärda skepp till Asien, där de plockas isär under extremt hälso- och miljöfarliga förutsättningar. Komplexiteten i det sjörättsliga systemet försvårar implementeringen av de juridiska instrument som finns tillgängliga för att förhindra de undermåligaShipbreaking, also referred to as ship recycling, is a dirty and dangerous industry. Economic motives drive shipowners to export their unwanted vessels to Asia, where they are dismantled under conditions extremely hazardous to human health and the environment. The complexity of the maritime system makes it difficult to implement the legal instruments available to prevent the substandard practices,
This thesis regards the study of cellular automata, with an outlook on biological systems. Cellular automata are non-linear discrete mathematical models that are based on simple rules defining the evolution of a cell, depending on its neighborhood. Cellular automata show surprisingly complex behavior, hence these models are used to simulate complex systems where spacial extension and non-linear re
This study aims to examine the Azerbaijan social work students’ views of their professional role in relation to the prevailing environment of an FSU country. The main objective is to identify the students’ views of different key themes; professionalization, identity and knowledge frames of social work to appraise the relevance of these under the development of the profession and in particular for
Following the refugee crisis in 2015, Sweden experienced the largest inflow of refugees in the country’s history. What are the effects on crime of such extensive immigration? This paper aims at analyzing if it prevails a causal relationship between the last years’ refugee immigration and crime rates in Sweden. For this purpose, data from the state’s refugee placement program is evaluated, which yi
In this essay, our aim was to investigate the correlation between deaths due to a terrorist attack an the medial attention of the attack. We do this to test and further expand Virgil Hawkins’ theory about stealth conflicts, where he emphasizes that the most violent conflicts of the world are underreported and in some cases ignored in favor of so-called chosen conflicts, which are on the medial age
Denna kandidatuppsats ämnar undersöka hur förslaget till direktiv om bättre arbetsvillkor för plattformsarbete kommer att påverka korrekt fastställande av sysselsättningsstatus bland plattformsarbetare. Felklassificering av sysselsättningsstatus bland plattformsarbetare har blivit ett allt större problem, med en beräknad fem och en halv miljon människor som på senare tid riskerar att få sin sysselThis thesis seeks to investigate how the proposed Directive on improving working conditions in platform work will affect the classification of employment status among platform workers. The misclassification of employment status among platform workers has become an ever-growing issue, with an estimated five and a half million people being at risk of employment status misclassification as of la
Personlig assistans är en viktig stödinsats för personer med funktionshinder. Två rättsfall på senare tid, HFD 2012 ref. 41 samt HFD 2015 ref. 46, har dock medfört att flera brukare fått sin assistans indragen samt att fler fått avslag på sin ansökan om personlig assistans. Det är domstolens restriktiva tolkning av begreppet grundläggande behov i de två rättsfallen som föranlett denna utveckling.
This thesis aims to investigate the accuracy of Value-at-Risk and Expected Shortfall forecasts of various GARCH-type models based on five currency exchange rate pairs. The GARCH models are employed under different conditional distributional assumptions, and extended using the two-stage Extreme Value Theory (EVT) approach of McNeil and Frey (2000). The forecasts are evaluated through simulation usi
As the population is growing and planetary boundaries are being strained, the agro-food industry is facing major challenges. Previous research has proposed the innovation of vertical farming (VF) as a potential solution. This study contributes to the existing VF literature with an examination of the opportunities and obstacles for the implementation and upscaling of VF in Sweden. The VF industry i
This report focuses on CFD-calculations using parallel processors carried out with the software Fire Dynamics Simulator (FDS). From a users point of view the advantages and disadvantages with parallel CFD-calculations were analyzed and evaluated. A simplified me-thod for quantitative evaluation was developed with guidance from ASTM E 1355 whereu-pon relative differences between serial reference sc
There are several accident investigation methods and they are used in a wide range of fields. However, the methods have not been used so much in the fire accident area. In the present thesis, the methods’ capability to investigate fires and what they result in are explored. In addition, answers are given concerning how important the background information is for their applicability. First, a selec
NTRU is a public-key cryptosystem, where the underlying mathematical problem is currently safe against large-scale quantum computer attacks. The system is not as well investigated, as for example RSA, and the company behind NTRU has created the NTRU Challenges, to remedy this. These challenges consist of 27 different public keys of increasing size, where the task in each challenge is to calculate
