Analog-to-digital converters (ADCs) with high conversion frequency, often based on pipelined architectures, are used for measuring instruments, wireless communication and video applications. Successive approximation register (SAR) converters offer a compact and power efficient alternative but the conversion speed is typically designed for lower frequencies. In this thesis a low-power 12-bit 200 MS
I stora delar av världen är deponering den dominerande metoden för avfallsbehandling. Bara inom EU skiljer det sig mellan länderna, då vissa deponerar över 90 % av sitt avfall medan andra idag deponerar under 10 %. När avfallet i deponin bryts ner bildas metangas, som är en kraftig växthusgas. Denna gas måste därför tas om hand genom förbränning. På senare år har allt högre krav börjat ställas på
This thesis investigates how context-awareness and learning from user patterns could improve the user interaction for a smartphone applica- tion that can control the computer and home and how it could create a smarter more personal experience. It looks at both how a existing cus- tomers would react in three different experiments (a survey, interviews and a prototype of the application), and how no
The purpose of this thesis has been to investigate and analyze swedish social worker’s experiences of working according to Lean as a work-method. This study was executed in two departments within the social services in southern Sweden. In the municipality in which the study was performed, Lean has been active as a work-method within the public sector for a few years. To better reflect the experien
Den psykiska ohälsan bland ungdomar har ökat de senaste decennierna. Ungdomsmottagningen är en viktig instans i främjandet av ungdomars psykiska hälsa samt i förebyggandet av psykisk ohälsa. Det är därmed väsentligt att den psykosociala verksamheten på ungdomsmottagningen anpassas till besöksgruppen samt dess behov av stöd. Syftet med studien var att kartlägga besöksgruppen hos den psykosociala peMental ill-health among adolescents has increased over the past decades. The youth clinic is an important instance in promoting mental health and preventing mental ill-health. Hence, it is important to adjust the psychosocial work to the visit group and its needs of support. The purpose of this study was to chart the visit group at the psychosocial staff at the youth clinic in Region Skåne. This w
Performing fault localization is one of the most time consuming and expensive aspects of software development today. In large software systems the manual fault localization techniques quickly become unmanageable and as such there is a growing need for automated solutions. In this master’s thesis we propose and evaluate a new method for fault localization based on comparing code coverage and diff u
This paper empirically examines the relationship between fuel prices and patenting activity in environment-friendly technologies in the auto industry across the OECD countries for the period 1994-2011. Overall, the results suggest that tax-inclusive fuel price affects innovative activity in environment-friendly technologies. More specifically, the analysis shows that the technologies aiming to red
Wetlands are natural ecosystems that are valuable in many aspects since they offer multiple benefits. According to the Environmental Code wetlands larger than 5 ha are licensed water activities. As the authorization process can be both time and resource consuming this study aims to study the process and try to identify where there may be gaps or obstacles. Since wetlands are valuable ecosystems, i
The German wasp Vespula germanica is found in the Palaeartic region of the globe. Outside this area, it is highly invasive species. It has an omnivorous diet and is able to hunt other insects and scavenge for food from both natural and anthropogenic sources. It has been previously shown that this species has efficient and specialized foraging strategies depending on the resource. It is capable of
Purpose: The purpose of this study is to gain a deeper understanding and contribute with knowledge of older people’s online behavior, with a particular focus on the process of social identity construction on Facebook. Theoretical framework: The theoretical framework consists of theories related to self and identity, in both an offline and online context in order to obtain a more complex and nuan
Some consider increasing income inequality within countries as one of the biggest threat to the world economy in the year of 2015. Increasing within country inequality creates both political as well as economic insecurity. It erodes economic initiatives as well as democracies and people are left in exclusion, which undercut the ideal of human equality. In the light of the above, this thesis invest
The relational database has long been considered the de facto standard for managing data in software applications. Today, a need for more scalable, flexible and distributed software solutions has led to the development of NoSQL database technologies that aim to replace the relational database in applications where such features are needed. In this thesis we have investigated the potential benefit
This thesis is the culmination of an action research project conducted at Axis Communications, which tries to enable test selection based on historical test data. In order to realize this, a prototype program -- the Difference Engine -- was created, which can parse and analyze historical test data drawn from a large database. The analysis produces a weighted correlation between code packages and t
Thermoelectricity is the physical principle of converting heat energy directly into electrical energy. Devices based on this principle so far fall short on efficiency but future thermoelectric devices based on QDs can have very high efficiency. Before QDs can be used in actual devices their behavior must the studied to a further extent. This work theoretically explores how a QD in a single electro
Uppsatsen behandlar innebörden av fastighetslandets exklusiva behörighet vid talan avseende sakrätt i fast egendom, enligt art. 24.1 Bryssel Ia-förordningen (förordning 1215/2012), samt dess relation till svensk internationell privat- och processrätt. Närmare bestämt utreds förhållandet mellan EU-domstolens autonoma tolkning av bestämmelsen och de motiv som sägs ligga bakom den exklusiva behörighe
I FBL 3 kap. 1 och 5 §§ finns de allmänna lämplighetsvillkoren för en fastighet respektive de ekonomiska krav som ställs för jord – och skogsbruksfastigheter. Dessa villkor gäller vid ombildning eller nybildning av en fastighet och vid en servitutsåtgärd. Undantaget från dessa lämplighetsvillkor finns i FBL 3 kap. 9 § som säger att ”Fastighetsbildning får äga rum, även om fastighet som nybildas elIn the real property formation act 3 chap. 1 and 5 §§ you will find the general conditions of suitability for a property unit and the financial requirements for agricultural - and forestry property units. These conditions should be fulfilled in every conversion or the formation of a property unit and at an easement action. The exception to these conditions is in the real property formation act 3 c
Konsumtionen har ökat 25 % de senaste tio åren och har blivit en allt viktigare del i individens liv. Den ökade konsumtionen innebär både fördelar och nackdelar för individen. Uppsatsens syfte är att diskutera vilka anledningar och motiv det finns för den unga storstadsbon i Sverige att konsumera. Syftet är även att se om det finns samband mellan konsumtion och identitet. Metoden som har använts i
In this thesis we consider the boundary value problem (*) u''+((n-1)/r)u'+f(u)=0,(r > 0, n > 1), u'(0)=0, lim(r->infinity)u(r)=0, where f satisfies a number of appropriate conditions. Under these assumptions, a theorem states that for every nonnegative integer m, (*) has a solution u(r) with exactly m zeros in (0,infinity). A proof, using a scaling argument and a shooting method is
