The project was performed for FAS Converting Machinery AB (FAS) in Ystad with supervision from Industriell Elektroteknik och Automation at LTH. FAS is a company that makes machines for producing plastic bags on a roll. The problem given was to develop a sensor for detecting the perforations in the bags to ensure that the correct amount of bags was rolled up and that the tearing was in the right pl
The term bibliotherapy is well known in several scientific fields as well as among practitioners in the US and in the UK, but in Sweden there seems to be a more modest use of the term as well as presence of practical bibliotherapeutic activity. On the other hand, some of the effects of reading that are commonly associated with bibliotherapy in the scientific literature seems to be similar to the e
Popular Abstract in Swedish Ett nytt EU-direktiv om uttjänta fordon har nyligen antagits. Direktivet kräver att från och med 2006 skall 85% av bilens vikt återvinnas och 95% från och med år 2015. Idag återvinns cirka 80%. Bildemonteringsindustrin har valts som studieobjekt i denna avhandling. De höjda återvinningskraven förväntas leda till att bildemonteringsindustrin genomgår omfattande rationaliA new EU directive on used vehicles has recently been introduced. It demands that for every scrapped car, at least 85% by weight must be recycled by the year 2006 and 95% by 2015. The current level is about 80%. The car disassembly industry was chosen as the study object of this thesis. Due to the increased demands on recycling, the disassembly industry may undergo comprehensive rationalizations a
Popular Abstract in Swedish I många utvecklingsländer i tropiska klimat leder den snabba urbaniseringen till många problem, bl a försämrad termisk komfort i utemiljön. Detta har negativa följder för människors hälsa och välbefinnande och påverkar sociala och kommersiella aktiviteter utomhus negativt. Följaktligen är det mycket viktigt att åstadkomma komfortabla mikroklimat i urban miljö. Den huvuIn many developing tropical countries, rapid urban growth leads to several problems, including increased thermal stress. This has negative consequences for people's health and well-being, and affects social and commercial outdoor activities negatively. Consequently, the creation of thermally comfortable microclimates in urban environments is highly important. The main aim of this thesis is to dee
Detta arbete handlar om en behandlingsteknik för hudterapi där lågenergetiska elektroner utnyttjas för strålbehandling där patienten står eller sitter på en roterande plattform. För att behandlingen skall få ett lyckat resultat krävs en viss stråldos (den absorberade energin per massenhet) till patientens hud. För att kontrollera att dosen är rätt används normalt mätningar med olika detektorer. DeBackground and purpose: This study refers to a rotational radiotherapy technique for the treatment of mycosis fungoides. Patients are irradiated by a high dose-rate low-energy electron beam while they stand on a rotating platform. This report presents a first effort to use the Geant4 simulation program to calculate the relation between the stationary and rotational depth dose distributions in an e
The purpose of this thesis is to explore and analyze the processes and efforts involved in rebuilding the war-torn state of Afghanistan. The examined period span from the fall of the Taliban regime in 2001, to the elections in 2005. This period, commonly known as the Bonn-process, sets out the initial time for the reconstruction of the state. A theoretical framework, which considers the necessary
The characteristics of an Elekta amorphous silicon (a-Si) electronic portal imaging device (EPID) in response to a 6 MV photon beam generated without a flattening filter, an unflattened beam, have been determined. The characteristics were then compared to those for a conventional photon beam generated with a flattening filter in the beam, a flattened beam, in order to determine the suitability of
Optical diagnostics are remote non-intrusive sensing techniques. The thesis work concerns the use of OH and soot optical diagnostics for combustion research.Internal combustion (IC) engines are widely used for the generation of power and for transportation purposes. Soot emission, involving carbon particles that emanate from the combustion process, is one of major sources of pollutants in engine e
Objective: To investigate the influence of cardiovascular risk factors, including fasting plasma glucose (FPG), on the association between electrocardiographic (ECG) and echocardiographic left ventricular hypertrophy (LVH) in an elderly population. Methods: We tested cross-sectional associations between electrocardiographic and echocardiographic LVH, defining LVH according to the Sokolow-Lyon volt
A novel calculation methodology containing modeling and statistics was developed to assist the experimental process for the investigation of organics treatment process. A continuous-flow photo-electro treatment of Norfloxacin (NOR) was chosen as a target subject. The methodology is based on a new synergistic work of reaction energy calculation, full-scanned neural network (NN) simulation and new p
Context. Measuring the abundances of neutron-capture elements in Galactic disk stars is an important part of understanding key stellar and galactic processes. In the optical wavelength regime a number of different neutron-capture elements have been measured; however, only the s-process-dominated element cerium has been accurately measured for a large sample of disk stars from the infrared H band.
Tailoring the activity of an organometallic catalyst usually requires a targeted ligand design. Tuning the ligand bulkiness and tuning the electronic properties are popular approaches, which are somehow interdependent because substituents of different sizes within ligands can determine inter alia the occurrence of different degrees of inductive effects. Ligand basicity, in particular, turned
Context.Gaia's third data release provides radial velocities for 33 million stars and spectroscopically derived atmospheric parameters for more than 5 million targets. When combined with the astrometric data, these allow us to derive orbital and stellar parameters that are key to understanding the stellar populations of the Milky Way and to perform Galactic archaeology. Aims. We used the calibrate
This thesis concerns the nature of cognition. It posits that cognitive processes primarily are means to maintain allostasis in organisms whose ecological niches require movement to approach food-resources and avoid predation. Hence triggering, or motivation, of behaviours are a consequence of prediction errors from the body resulting from biological variables moving away from homeostasis. Dependin

Pollinating insects are declining due to several threats, one being a loss of flower resources because of a change of land use. With rural agricultural areas becoming more homogenous, urban areas might provide refuge for pollinating insects. The main aim of this study was to investigate how the trees in the city of Malmö, Sweden, contribute with food resources, i.e. nectar and pollen, both spatial
The design of an axial compressor is mainly the trade-off between efficiency, stability and cost. A parameter that affects all of these three aspects is the blade aspect ratio. Due to the intricacy and complexity of the flow in a compressor, solely the effect of the blade aspect ratio variation is difficult to obtain. A parameter that supposedly is a gauge of the combined airfoil and end wall loa
The main focus of this thesis has been to examine and compare how the size and number of internal power transformers affects the technical performance (robustness, power quality and efficiency) of a utility-scale PV plant. The technical performance was examined in a simulation environment (MATLAB Simulink), where a PV plant with a fixed number of PV arrays and converters, corresponding to a rated
I takt med den växande digitaliseringen förändras förutsättningarna för arbetslivet och medarbetare ställer nya krav på sina arbetsgivare. Arbetet med Performance Management behöver förnyas för att möta framtidens behov. För att öka förståelsen för vad som får medarbetare att bli engagerade i sitt arbete, granskades IKEA och deras mål- och utvecklingsprocess.
