The goal with the project is to develop a functional method. Two printing trials have beenperformed.
Automatisk viktkontroll av glascontainer
This degree project has been carried out in cooperation with Gedevelop in Helsingborg.Gedevelop has developed a camera that can calculate the weight of a liquid glass mass.Because of the density and viscosity changes in the glass, the weight information issometimes incorrect given. Glass industry is today addressing the problem by an operatorperforming a manual Weighing of a few bottles which, in turn, calibrates the camera system.The project aimed to develop an automated system to control the Weighing of glass bottles forglass industries. This system must be so flexible that it can be easily mounted on plants withdifferent production equipment around the world.The project includes design and construction of equipment that meets the requirementsformulated together with Gedevelop. Work has been done both in Halmstad and Helsingborgand has included both calculations and review of the theory to understand the forces thatinfluence the design of different construction parts. A prototype was produced that meets theoperating requirements for the design and can be used in testing features.
Intresseavvägningen i personuppgiftslagen - Det kommersiella intresset
Personuppgiftslagen (1998:204) är en lag som syftar till att skyddavåra personuppgifter. Huvudregeln i personuppgiftslagen är attsamtycke krävs från den som personuppgifterna tillhör för att de ska fåbehandlas. Till denna huvudregel finns det dock ett viktigt undantagsom stipulerar att om behandlingen är nödvändig får den utföras utansamtycke, om exempelvis ändamålet uppfyller ett berättigat intressehos den som ämnar behandla uppgiften som väger tyngre än denenskildas intresse av skydd för den personliga integriteten. När ettsådant berättigat intresse ställs mot den personliga integriteten blir enintresseavvägning nödvändig för att avgöra om behandlingen skallvara tillåten eller ej. Det berättigade intresset som upptar dennauppsats är det kommersiella intresset, som exempelvis omfattar ettföretags intresse av att behandla personuppgifter för att via direktmarknadsföring marknadsföra sina produkter.

Lagerhantering i framtiden på Aero Materiel AB
In recent years, increasing emphasis has been placed on streamlining the supply chain. Keeping inventory and warehouses is considered to be a waste of resources. It is however difficult to completely eliminate the need for inventory and warehouses in a supply chain. The purpose of warehousing is to provide a service for the customer. By keeping what the customer demands in inventory it is possible to make a quick delivery when a need arises.
Belastningsregister : En balansgång med den personliga integriteten
At the time of the study, there is no law to prevent an employer from doing criminal background checks. Employers for School and childcare have to do criminal background checks before hiring but the background checks have increased significantly in other industries as well. The aim of this thesis is to analyze and explain what interest employers may have in jobseekers history and how it can affect people?s privacy. To do this I have used right dogmatic approach combined with four interviews with different employers to get their perspective on the subject.
Tillskottsutfodring av smågrisar under digivningsperioden :
Weaning is one of the most critical events in the piglet production with problems such as growth check and post-weaning diarrhea as a result. The lighter the piglets are when the growth check occurs, the harder they have to get back to normal growth rate. Creep feeding of piglets is used to reduce the problems by increasing the weaning weight and adapting the digestive tract to a starter diet. Hodge (1974) showed that the sow?s milk can not provide enough nutrients for maximal growth rate.
Hur bedöms vallens avkastning?
Grassland is a great part of Swedish agriculture and there is a demand of what the grassland yield is in practice. To be able to control the economic of the milkproduction it is important for the farmer to know how big quantities of pasture there is to use during the year.The work is based on interviews of 22 farmers from southern part of Sweden. Their area of grassland fluctuate between 16 up to 360 hectares. The questionnaire content 32 questions.The most common way to weight the green plant material is to drive over a scale, and to measure the dry extract with your own gauge. It takes in average two minutes toweight one load of green plant material.
Kunskapens värde. Mot en dygdepistemologisk position
"The Value of Knowledge - Towards a Virtue Epistemological Position" The classical question, first posed in Plato's Meno, concerning the value of knowledge constitutes the starting point of this essay. Value analysis has long been neglected in epistemologist's accounts until its re-emergence with the tradition called ?virtue epistemology?, in particular with scholars following Ernest Sosa. Like virtue ethics virtue epistemological accounts changes the focus from the object to the agent, i.e. from knowledge to intellectual virtue.
Trä och fukt ? Mätmetoder för fuktrelaterade dimensionsförändringar hos trä och deras användbarhet, med två fallstudier inom konservering
This thesis deals with different methods for measuring moisture-related dimensional changes ofwood. Typically relative humidity is measured to determine if the ambient climate around anobject is harmful to it or not. Values between 40 to 65% RH are recommended for hygroscopicmaterials. To know how a wooden object actually reacts to changes in the surroundingenvironment requires methods that involve the object itself. Because of the wood anisotropy,differences in wood structure, finishes and other restraints, it is not always possible to predict themovements.This paper addresses various measurement methods, primarily methods that have been testedin the field of conservation, with examples of their use.
Optimering av driftläggningar i Fortums nät
Future emission legislation puts great emphasis on increasing the efficiency of the engine, thereby reducing fuel consumption. The tribological contact between cylinder liner and piston ring is where an great amount of energy is lost due to friction, and by reducing these losses an reduction in fuel consumption can be achieved.The aim of this thesis was to evaluate the tested piston ring coatings against a plasma sprayed cylinder liner and rank these combinations of materials for friction and wear resistance. The coatings that were tested was Cr + Al2O3, (Al,Cr)N, two types of CrN and WC / C.The experimental tests were performed with a so-called pin-plate, where used oil with addition of an acidic mixture of sulfuric and nitric acid to mimic the acidic condensate formed when exhausts recirculate, were added with a continuous flow. The results were then analyzed by Weighing, studies by optical microscopy and scanning electron microscopy (SEM) and profile measurements.The results from each material combination were that the plasma coated cylinder liner wears too aggressively in order to yield a ranking of the piston ring coatings based on the parameters of friction and wear resistance. It is therefore proposed that an alternative coating on the cylinder liner should be developed, lacking the large abrasive wear on piston rings and that can withstand the corrosive environment resulting in engines equipped with EGR.

Individuell utprovning av inkontinenshjälpmedel i kommunala särskilda boenden
The purpose of this study was to examine the extent to which incontinence aids, used in local authority/municipal nursing homes, were adapted to the resident?s urine-leakage volume and to find out how nurses perceived the current situation concerning individual testing of incontinence aids in municipal nursing homes. The study method was a quantitative empirical study and was carried out in two phases. The first phase was a Weighing test, carried out in three nursing homes, whereby the incontinence aids used by 25 residents during a 48 hour period were weighed. The second phase was the completion of a questionnaire by the municipal nurses working in the same local authority.
Effect of liming and free Ca2+ on Cd uptake of carrots, Daucus carota
The level of cadmium (Cd) in Swedish arable land has increased during the last century and the average concentration of Cd in the plough layer is today 0.23 mg/kg. The increase is mainly due to anthropogenic activities such as phosphorus fertilizing, liming, import of feed, and atmospheric deposition from industrial emissions. Cadmium in the soil will be taken up by crops and is thereby transferred to humans via food. Carrot is one of the crops of concern, both because it may contain quite high Cd concentrations and due to the large consumption in Sweden. In the body, Cd is stored mainly in the liver and the kidneys and may cause several diseases already at low concentrations.
