Energy harvesting enables products to become more self-sufficient of power and offers the possibility to avoid battery exchange and power cables. The performance and applicability of the most promising or popular small scale energy harvesting technologies are investigated in this thesis. The focus lies on the amount of potential energy that can be harvested and how limited the technology is to a s

Organizations struggle to rapidly respond to competitive and changing business environments and therefore implement smarter Information Systems that incorporate automated decision services. An imminent role for complementing automated decision making are analytics, as it can evaluate past performances to provide insights on potential future decision making endeavors.

Digitalisering av sjukvården tar idag stor plats i samhällsdiskussionen och ses som ett sätt att möta utmaningarna sjukvården står inför. En förutsättning för ett effektiviserat sjukvårdssystem är en förstärkt och effektiviserad primärvård. E-hälsa och digital teknik är viktiga verktyg för att kunna uppnå detta. I Sverige finns ett fåtal digitala vårdcentraler. För att de ska vara en långsiktig lö

This study examines if there are positive effects of constructing portfolios based on value and momentum. Three value portfolios (low, medium, high) and three momentum portfolios are constructed using large cap stocks from the four Nordic Nasdaq OMX exchanges. The portfolios are then re-sorted on an annual basis over the test period 2005-2016. Furthermore, two long-short market neutral portfolios

Den här fallstudien syftar till att analysera och förklara varför ett visst samhälle i Anderna i norra Peru som arbetar och fungerar under kooperativ som social ordning har varit relativt sett framgångsrik när det gäller att skapa arbetstillfällen och en till synes mer utvecklad organisation. Atahualpa-Jerusalen bildades som ett kooperativ I kölvattnet av jordreformen från 1969 i Peru. Under 1970-This case study aims to analyse and explain why a specific community in the Andes of Northern Peru working under the social organisation of cooperative has been relatively successful in creating work opportunities and an apparent higher level of development and organisation. In the aftermath of the agrarian reform in Peru of 1969 Atahualpa-Jerusalen was formed as a cooperative. In the seventies, m

In 2016, a new restrictive asylum law was passed in Sweden, which limits asylum seekers’ possibilities of being granted residence permits and being reunited with their families. The passing of new restrictive asylum in law is interesting, since values such as solidarity and cosmopolitan ideals are deeply entrenched within the Swedish welfare state, which were evident in expansive immigration polic

There is an upsurge of consumer interest in functional foods, especially probiotics. Alongside there is a global rise in the ‘vegan’ market. However, there is insufficient research and development in the field of non-dairy probiotic food formulations. Development of probiotic oat-based yogurt, called oatgurt that is manufactured by Oatly AB, was studied by incorporating Lactobacillus plantarum 299

In industrial production of mayonnaise it is important to both get a product of high quality and to avoid phase inversion. To investigate how the quality and phase inversion point are affected by changes in the production, a high shear mixer and an immersion blender were used to make mayonnaise. The stirring speed, temperature, egg content, egg type and oil content were changed to see how the qual

Motivation and Objective: This study investigates how analysts generate from data using business intelligence tools. The motivation for study at the premise that organizations are finding it very challenging to gener-ate insights from a vast amount of structured, semi-structured and unstructured data. The ini-tial problem background indicate that this may be because organizations are silo driven,

The aim of this thesis is to survey and map out what it means to believe in unexplainable phenomena, that is phenomena not scientifically explained, in a secular late modern society. The study is explorative and used methods are five focus group interviews supplemented with a questionnaire, performed in southwest of Sweden. Used theories in the inductive analysis to explain belief in unexplainable

The round goby (Neogobius melanostomus) is a non-indigenous species to the Baltic Sea that has drawn the attention of many researchers in the last decade due to its rapid spreading and its impact on the local fauna. With recent concerns about the dispersal of the round goby towards the North Sea, the aim of this study was to determine if the native shore crab could compete with the invaders and pr

Uppsatsen undersöker röst, perspektiv samt den rytmiska och stilistiska presentationen av dessa i Kristina Sandbergs roman Liv till varje pris. Uppsatsen undersöker romanens mångstämmighet och därmed dess eventuella polyfoni och dialogicitet.

The aim of this thesis is to find out whether the political council in the municipalities is important for the outcome of work towards sustainable development. With increased migration into cities and increasingly major environmental problems, humanity is facing serious consequences if nothing is done. The municipalities in Sweden have great opportunities to reverse the bad trend. I examine ten mu

This research explores the processes of articulation between indigenous-ancestral knowledge practices of childbirth and the biomedical logic that articulates the field of medicine and state interventions. It unravels the question of: how do government policies in Ecuador construct the discourse around the dynamics between traditional-indigenous childbirth and biomedical interventions, and what imp

This thesis examines the possibility of modelling trajectory and estimating distance during a walk using only a smart phone attached to the waist. Due to GPS not functioning indoors, a navigation system without the need of external communication could be the perfect complement for closed spaces. This thesis considers such a system, where the smart phone contains accelerometer and gyroscope sensors

Caldicellulosiruptor species are regarded as the best microorganisms to produce hydrogen due to their ability to break down many types of sugars and hydrogen yields near the theoretical maximum. The major drawback is their low volumetric hydrogen productivity (QH2), which makes the current process setup economically non-viable. In this study, the natural capability of Caldicellulosiruptor species

Denna kvalitativa studie har haft som syfte att förstå hur den globala kampanjen #metoo har påverkat intervjupersonerna och deras inställning till sexuella övergrepp. Avsikten med #metoo har varit att uppmärksamma omfattningen av kvinnors utsatthet för sexuella övergrepp. Tidigare undersökningar och statistik visar på ett stort mörkertal när det kommer till offer för sexuella övergrepp och det är

Rapsfält – ett överflöd av mat eller en gul öken för vilda bin? Gula rapsfält har blivit en allt vanligare syn under försommaren i Sverige, ett hav av gula blommor rika på både pollen och nektar. Samtidigt går det allt sämre för de vilda bina världen över och många frågar sig om inte raps kan tänkas hjälpa de vilda bina på traven att förhindra att bina blir ännu färre. För utan bin förlorar vi enPollinators are important for both the agricultural landscape and natural areas, but currently many pollinator groups are declining. Pollinators have a strong relationship with plants, which humans long have benefited from. Nowadays, 35 % percent of the human food production somehow relies on animal pollination. Therefore, unravel the details about crop pollination and its relationship to differen
