Problem. With the Swedish public sectors problem with efficiency in mind, several reforms have beeninitiated during the last decades. These reforms go, in academic contexts, under the name?New public management?. The reforms have resulted in, among other things, an increasedcompetition, privatization and goal-orientation in the public sector.

Värmeöverföring i bergvärmesystem : En numerisk analys av den ringformade koaxiala borrhålsvärmeväxlaren

The borehole heat exchangers of today suffer from poor thermal and hydrodynamic performance. The purpose of this thesis is to improve the performance of ground source heat pump systems and thermal energy storages by increasing the energy efficiency of the borehole heat exchangers. For this reason, the annular coaxial borehole heat exchanger (CBHE) has been analyzed. This type of heat exchanger is interesting in terms of both thermal and hydrodynamic performance. A model has been set up in the program Comsol Multiphysics in order to investigate the heat transfer characteristics along the borehole.

Returhantering vid LensLogistics AB: en process- och
flödesutredning för förbättringar

Return handling is often regarded as a slow and complex process. Studies have shown that it is not unusual for a return to cost up to nine times as much as a standard outbound delivery. An efficient return handling process is therefore essential to all competitive companies dealing with logistics. This report investigates, analyzes and gives suggestions on development with the purpose to improve the return handling process at LensLogistics AB in Kista, north of Stockholm, Sweden. The study has been conducted from a deliberately practical point of view in order to suggest improvement suggestions possible to implement and thereby change the entire return handling process.

Framtagning av en utvecklingsprocess för automation - baserat på konceptet Lean Automation

Due to the globalization today the competition in the market has in- creased and it requires flexibility and produce according to customer demand. In order to reduce the cost of wages industrial companies are now considering moving the manufacturing to low-cost countries. To keep up with the competition in the market without moving the manu- facturing abroad, Lean Automation was developed. The concept of Lean Automation is to reduce the perceived complexity with automa- tion and make automation available for new users and in new applica- tions.Haldex Brake Products are situated in Sweden and want to maintain the manufacturing of the automatic brake adjusters in the country. It is a product well-known and highly exposed to the competition in the mar- ket.

Effektivisering av råvarulager för lagerhållning av ett bredare artikelsortiment

SUMMARYInventory of raw materials holds an important role in companies within the manufacturingsector. The inventory works as a buffer that secure the supply of materials to the productionunit. The aim of the inventory is to ensure that the company is able to meet the customers?demands despite fluctuations and variations in the material flow. The size of the warehouseand the layout are physical limitations for the quantity of articles that can be stored.

Arbetsmiljö inom äldreomsorgen : en studie om enhetschefens resonemang och förhållningssätt i arbetsmiljöfrågor

The occupational group who works in the care of older people in Sweden is an exposed group since the work is often defined as a strenuous profession, both physical and psychically, and this puts comparatively many workers on sick leave. To promote good health, as well as prevent bad health is the main purpose of the work environment development. The attitude of the care manager towards work environment development may have a significant impact on the co-workers health. The purpose of the study was to investigate the attitude of care managers towards work environment development and the co-workers work environment and in the same time get knowledge in what issues they have a salutary approach respectively a pathological approach. Empirics were gathered from semi-structured interviews with six care managers from the care of older people administration in municipality of Kalmar.

Strokekedjan från början till slut : En etnografisk studie om farlighet och tid i en akut vårdkedja

Varje år drabbas 30 000 svenskar av stroke, vilket innebär stora personliga omställningar och stora kostnader för samhället. Den mest effektiva behandlingen, trombolys, måste ges så snart som möjligt för att ha god effekt.  Samtidigt som det är av största vikt att ta reda på om patienten har några differentialdiagnoser som gör behandlingen riskfylld.Den här studien undersöker hur strokekedjan går till och vilka faktorer som påverkar beslutsfattandet. Studien är baserad på etnografiska fältstudier på fyra svenska sjukhus och materialet är analyserat med metoder från sammansatta kognitiva system och målorienterad design. Resultaten visar att trots olika organiserade strokekedjor på de olika sjukhusen är processerna desamma och direkt kommunikation är mest framgångsrik för att effektivt sprida information mellan dem. Neurologjouren är viktig roll som, liksom resten av aktörerna i strokekedjan, ständigt balanserar sitt beslutsfattande mellan effektivitet och grundlighet.

Den interaktiva IR-forskningens genomslag i söktjänsterna på webben

The theoretical focus in this master is information retrieval (IR), and especially the part of IR that includes interactivity. This research is by some researchers called IIR. Our principal aim was to examine if search engines on the WWW are taking advantage of research results from IIR research. A way to do this is to look at the application of special features, in this case query expansion (QE) and relevance feedback (RF). Both these methods aim for a better matching of documents and the searchers information need.

Passiva lantbrukare ? en effekt av EU:s jordbrukspolitik : en studie av ett antal faktorers påverkan på svenska passiva lantbrukares attityder till markanvändning och EU:s jordbrukspolitik

The problem with passive farmers has arised as an effect of the European Union´s common agricultural policy (CAP) and the decouplement from production-based payments. Payments to passive farmers contradict the purpose of the single payment scheme and constitute a great cost for the EU. The new contractual period after 2013 has given rise to discussions on the direction of the CAP with a purpose of increasing the efficiency of the single payment scheme, and reducing passive farming. The aim of the study is to increase the knowledge about a few factors? influence on passive farmers? attitudes towards land use and the CAP.

Lysande rör, rörligt ideal : belysningsbranschens introducerande av lysröret i Sverige

During the 1930´s the hot potato for the Swedish lighting associations were how to create the most suitable light for every situation, either for industries, offices or homes. The light bulb were the most frequently used source of light but due to limitied luminous intensity, big halls sometimes required up to hundreds of light bulbs to produce the right amount of light. Two kinds of different lights, by different reasons, can be titled the predecessors of the fluorescent lighting during the 1930´s: The volfram-filament tube light due to its estetic similarities and the electric discharge (mercury- and sodium-) lamps due to its technical resemblance. Even though they came in quite wide use (the volfram tube in public halls (e. g.

Simulering av COD-fraktioner i en aktivslamanläggning vid en sulfatmassafabrik

This thesis work was made for Södra Cell Mörrums bruk in Blekinge. The purpose of the work was to develop a computer model in the simulation program Extend for the removal and balance of organic oxygen consuming substances, measured as COD (Chemical Oxygen Demand), in the new biological treatment plant in the mill. The plant produces two different pulp products, TCF- (Totally Chlorine Free) pulp and ECF- (Elementary Chlorine Free) pulp, for sale. The different bleaching procedures affect the characteristic of the wastewater and thus the effectiveness of the biological treatment plant.In the model that was developed the COD in the wastewater was divided into five different COD-fractions: soluble easily degradable (SS), soluble hardly degradable (SR), soluble inert (SI), particulate inert (XI) and particulate biomass (XB). To create the model FlowMac? was used as a base.
