Full textTo better and more easily manage the distribution- and production plans at Bic centralized inventory management software was installed in 2001. One of its input parameters is the security stock level. The existing way of calculating the security stock level is basic and demands a lot of time and work since it is principally done by hand. General theories linked to safety stock calculations is examined and put into relation to the particular case of Bic. The actual model is expanded with parameters influencing the safety stock level but none existing in the earlier model. For instance is studied how variability in lead time, biases between actual forecast and demand and the A,B,C-classification of the products can have influence on the safety stock level. Many products have no, or poor information on which the calculations can be based on. A system with different default values is proposed to solve this matter. Another problem is the dependence between co packaged- and factory products in the same inventory. To diminish the uncertainty in demand the theory of postponement is used and a stock transfer is possible between final products and their component products depending on their bill of materials. The proposed model takes form as a series of Macros in excels, automatically gathering information from existing data files. In the final application where the stock calculations are done the user is given freedom to choose or influence on many of the input parameters before running the program.

Full textLättelement AB projekterar och tillverkar byggelement i form av tak, vägg och bjälklag till den Nordiska marknaden. Merparten är takelement och huvudmarknaden är Sverige. I varje element sitter 4 stycken lyftpunkter. Lyftpunkterna används för att lyfta element, dra ihop element samt som infästning för fallskyddsutrustning. Lättelement AB har konstruerat en ny modell av lyftpunkt som de önskade få testad och hade för avsikt att ersätta den nuvarande lyftpunkten med den nya modellen om den har samma eller bättre lastkapacitet. Denna nya modell skulle underlätta vid tillverkning och montering av lyftpunkter. Det här arbetets syfte var att utreda ifall den nya lyftpunktsmodellen klarar de krafter som uppstår vid lyft och ihopdragning av element. Enligt de teoretiska beräkningarna skulle den nya modellen av lyftpunkt ha bättre kapacitet än den nuvarande. Under dragprovning visades oförutsedda brott och de praktiska värdena blev betydligt lägre än beräknat. Efter dragprovning beräknades bärförmågan utifrån den aktuella brottbilden och det kunde konstateras att beräkningarna och testresultaten stämmer relativt bra överens. Utifrån kraven som ställs på den nya modellen av lyftpunkt uppnås inte de önskade hållfasthetsvärdena för att kunna ersätta den nuvarande modellen. Det här arbetet är dock ett bra underlag för vidareutveckling av lyftpunkten. Nu är det känt vad som sker vid brott för den här typen av lyftpunkt. Det ger en möjlighet att konstruera en lyftpunkt som skall klara den önskade bärförmågan och samtidigt kan vara smidig ur ett produktionstekniskt perspektiv.

Full textWhen construction parts are tested in order to try and classify the fire resistance, the standard fire curve is almost only used. The standard fire curve defines exposure from temperature over time. The fire exposure is described in the European standard EN 1363-1 and in the international standard ISO 834. The standard fire curve was defined for over 100 years ago, in a time when the knowledge in fire design was inadequate. Now days the standard fire curve is a bit modified, but it almost remains the same as the fire curve defined for 100 years ago. Another way to design construction parts is theoretical by using parametric fire curves and the material models in the Eurocodes. In EN 1991-1-2 appendix A, a method to calculate parametric fire curves is presented, the method results in temperature-time curves and is known as the Eurocode model. This method considers the final room geometry and fire load, it also contains a cooling phase unlike the standard fire curve. Therefore, the Eurocode model is considered to be better at describing real fires. Compartment and room fires based on geometries from real apartments, will be calculated with the Eurocode method in order to compare the temperature-time curves against the exposure of the standard fire curve. The project started with a study of former literature to give a deeper understanding in the current subject. After that, real apartment drawings were collected to represent real apartments. The drawings were then used as input for the calculation method in EN 1991-1-2 appendix A. To calculate in a more effective way an Excel spread sheet was created for the calculation method according to the Eurcode model, which later has been used for all calculations. Four different scenarios were created, including two different thermal inertia and two different opening factors for each thermal inertia. The reason why was that it seemed to be interesting to examine in what extent these parameters affect a fire. It resulted in that scenario 3, the scenario with a lower thermal inertia and a higher opening factor, were the scenario with the fastest growing fire and with the highest temperatures. In comparison with the standard fire curve, scenario 3 had a majority of fires that exceeded the standard fire curve’s temperatures until the cooling phase begun. Scenario 2 which had a higher thermal inertia and a lower opening factor resulted in the opposite, that is a fire burning during a longer time with overall lower temperatures. In comparison with the standard fire curve scenario 2 had a majority of fires with lower exposure of temperature than the standard fire curve, during the entire time of fire. The opening factor controls which amount of oxygen that flows in to the fire compartment, an increase of the amount of oxygen leads to a more intensive fire. The thermal inertia controls how slowly something gets warmed up, a lower thermal inertia means that the fire compartment warms up faster and resulting in higher temperatures as less energy is absorbed by the walls. The calculated compartment and room fires temperature-time curves was in a better agreement with the standard fire curve than expected. Given that the floor and roof is concrete, the walls is gypsum and together with the assumption that the fire load defined by Boverket is correct, is the conclusion that the standard fire works well in most cases. However, the fire growth rate is lower for the standard fire than for some calculated cases but have a temperature at 60 minutes that exceeds most of the calculated cases at the same time. The fire resistance tests can still develop since a big amount of the calculated temperature-time curves exceeded the standard fire curve in periods of time over 30 minutes, something that could affect the fire protection requirements. But the majority of the calculated fires had an exposure of temperature under the standard fire curve. Therefore, the standard fire and the requirements can sometimes be considered oversized based on the work that been done.

Full textOnboarding av nyanställda på arbetsplatsen är bland det viktigaste och samtidigt den mest förbisedda processen vid hantering av humankapital. Onboarding är det engelska uttrycket för introduktion samt socialiseringsprocessen vid nyanställning. Onboarding är viktigt eftersom organisationer investerar tid och pengar för att rekrytera nyanställda och därför har organisationen inte råd med att nyanställda hamnar i utanförskap i början av karriären. Viktiga aspekter av onboarding att hjälpa organisationer att se till att nyanställda blir mer engagerade i sitt arbete, förbättra deras integration in i organisationen, förstärka deras lojalitet till organisationen samt minska personalomsättningen. Idag finns få studier om onboarding gällande den offentliga sektorn. Syftet med denna studie är att först presentera ett förslag till en teoretisk modell för onboarding för offentlig sektor sedan studera en existerande onboardingprocess hos Region Gävleborg och därefter vidareutveckla den teoretiska modellen för onboarding. Studien har uppfyllt sitt syfte genom att ta fram en teoretisk modell baserad på teorier om onboarding och socialisering, modeller från den privata sektorn, befintliga onboardingmetoder samt en intervju med HR-strateg från Region Gävleborg. Författarna har även analyserat rådata från Region Gävleborgs enkätundersökningar för att få en bättre förståelse av nyanställdas upplevelse av Region Gävleborgs onboarding. Studien inledes med att en teoretisk modell togs fram, sedan utarbetades en onboardingmodell för Region Gävleborg utifrån kartläggning av regionens onboardingprocess. Därefter validerades den framtagna teoretiska modellen och den utarbetade onboardingmodell av Region Gävleborgs HR-strateg. Vidare jämfördes studiens första utkast till teoretisk modell med Region Gävleborgs modell samt en onboardingmodell från den privata sektorn, vilket resulterades i en vidareutvecklad ny teoretisk modell för onboarding inom den offentliga sektorn.

Full textOrganizations need qualified personnel to work effectively. Accordingly recruitment is an important organizational activity. Moreover, to attain sustainability for organizations, individuals, and the society, it is assumed important that new personnel adjust well to their working conditions. The aim of this thesis was to investigate the role of selection for long-term sustainable recruitment. The thesis includes three studies based on data from the recruitment of new police officers in Sweden. A cohort of new police officers was followed from the end of the admittance process to the basic police training program in spring 2008 (N = 1,344) and then at three consecutive follow-ups (N = 717-729), 1) at the end of two years of academy training, 2) at the end of six months of field training, and 3) at the end of the first working year. Study I aimed to further the understanding of how to select suitable police applicants by using combinations of common selection methods. Analyses of several criteria (performance, satisfaction, occupational retention, and health) at the three follow-ups suggest that combining information from cognitive, personality, and physical fitness tests, that in earlier hurdles have been used to screen out unsuitable applicants, would be useful in identifying the most suitable candidates, while interviews may primarily be considered as a tool for screening out any unsuitable ones. Study II focused on how to interpret and make use of results from cognitive tests in applied settings such as selection. In most occupations, including the police, cognitive tests are among the most valid predictors of performance. This has been explained by the influence of general intelligence. However, the results from Study II showed that beyond general intelligence, a verbal and knowledge loaded component can be important in predicting performance. Also, the study supported the use of total scores in selection. Study III aimed to examine the relative importance of selection factors (e.g., personality and general intelligence) and psychosocial working conditions for new police officers’ work-related attitudes and health. The study showed that psychosocial working conditions, such as opportunities for development and feedback as well as a balanced workload, were far more important than selection factors for the new police officers’ adjustment to their occupation. Taken together, the thesis shows the value of considering several time points and several criteria of successful recruitment. Also, it demonstrates the usefulness of combining information from several selection methods to select the most suitable candidates, along with the value of using verbally loaded cognitive tests in selection. Still, the ability to predict success among police officers by using selection methods remains modest. Additionally, the thesis shows that the working conditions for new personnel can be considered crucial if recruitment is seen as a long-term process that also includes the introduction phase. Accordingly, organizations striving for sustainable recruitment need to focus on developing sound selection processes and providing sound working conditions for their new personnel. This is of particular importance for organizations such as the police, where the costs of recruitment are high.

Efter en definition och begreppsförklarande inledande del presenteras en teoretisk genomgång av konsumtionsteori med en mer specifik vinkling mot teorier om kapitalvaror. Därefter kommer en empirisk studie där faktorer som behandlats i teoridelen tas upp som beroendevariabler för efterfrågan på kapitalvaran bil. Slutsatserna som dras är att räntenivån påverkar bilinköp mest, troligen för att kreditkostnaderna utgör en allt större del av hushållens disponibla inkomster. Dessutom bekräftas det att inkomsten fluktuerar mer än konsumtionen och detta gäller också för hushållens konsumtion av nya bilar.

Full textThis thesis work describes the development of a calculation model for stroke times of pneumatic cylinders and actuators. The stroke time of an actuator can be determined by experimental tests. To facilitate and reduce the time required in connection with the tests, a calculation model is created which presents theoretical values of the stroke time. This calculation model is qualitatively consistent with the experimental tests carried out in this work. The tests are first carried out on a simple pneumatic cylinder, which contributes to knowledge of stroke characteristics and stroke times. This knowledge is helpful for the development of the calculation model. During the tests the stroke time, chamber pressure and piston movement are measured in a variety of operating conditions. The tests show that one of the most critical parameters for the calculation model is the C value, a parameter that describes the flow characteristics of pneumatic components. To make the calculation model reliable, a reasonable C value need to be used. The calculation method consists largely of equations for filling and emptying of pneumatic volumes as well as pressure changes in the cylinder chambers during compression and expansion. With a combination of these equations it is possible to calculate the stroke time. Since the calculation model wants to be kept relatively simple, several assumptions are made about parameters in the system. These assumptions are evaluated according to their potential and impact on the stroke time. Validation experiments show that the calculation model generally works better at high supply pressures and critical flows. When the supply pressure is low and subcritical flow are obtained, the stroke time is affected by many more parameters, which lower the precision of the calculation model. This result is not entirely unexpected since the critical flow equations are relatively simple.

Full textHandledaren är en nyckelperson i studenternas utveckling till professionella sjuksköterskor. Syftet med denna studie var att undersöka och beskriva sjuksköterskors uppfattning om omvårdnadshandledning av sjuksköterskestudenter. Fokusgruppsintervjuer valdes som metod. Nitton sjuksköterskor deltog i intervjuerna. Materialet bearbetades. Två huvudkategorier formulerades: Egenskaper och Kompetens med ett övergripande tema: Handledningens kvalitet. I resultatet av intervjuerna framkom faktorer som har betydelse för en god handledning och utveckling av handledarrollen: handledarens- studentens och organisationens egenskaper samt pedagogisk- yrkes och social kompetens. Det framkom att viktiga kvaliteter både hos handledare och student är intresse och motivation samt ett gemensamt ansvar för studenternas lärande. Det efterfrågas faktorer som tid och acceptans för handledning från organisationen. En professionell sjuksköterska som är en bra förebild för studenten och har en god pedagogisk kompetens är bra handledare. För att kunna utvecklas i sin handledarroll efterlyser sjuksköterskorna feedback från sina studenter. Uppfattningen var att det är roligt att vara handledare och att det är en tillfredsställelse att lyckas föra en människa framåt i sitt lärande.
The preceptor is a key person in the students development to professional nurses. The purpose with this study was to examine and describe how nurses thinking of the preceptor ship for nurse students. Focus group interviews were chosen as method. Nineteen nurses participated in the interviews. The interviews were analysed. Two main categories were developed: Characteristics and Competence with a comprehensive theme regarding the nurses understanding of the quality of preceptor ship. The result of interviews showed factors of significance for the quality and development of the preceptor ship role: the preceptor, students and the organisations characteristics as well as pedagogical, professional and social competence. It was made clear that the interest and motivation as well as a mutual responsibility for the students learning is important qualities for both the preceptor and the student. Preceptors requested factors such as time and acceptance for preceptor ship from the organisation. A good preceptor is a professional nurse that is a good model for students and has a well developed pedagogical competence. To be able to develop one’s role as a preceptor, nurses are making inquiries about feedback from their students. The opinion of the preceptors was that it is amusing to be a preceptor and that it is satisfactory to succeed in leading a human forward in her development.

Full textA company needs an accurate capacity plan to become successful. The capacity plan is an important tool for planning and anticipating production which is essential to be able to meet future demands. It is therefore of great importance to get an accurate forecasting of the production capacity, which is the main topic of this report. During the spring semester 2016, the authors of this report were contacted by the production unit PET-Turbuhaler at AstraZeneca in Södertälje. PET-Turbuhaler requested an accurate model for the long term, 12-24 months, forecasting of their production capacity. From this problem, a research question has been formulated into; Which is the best way for PET-Turbuhaler to work to reach an accurate long term, 12-24 months, production capacity prognosis? A pre-study, a literature study and an internal and an external benchmarking were conducted in order to answer the research question. The result from these were afterwards compiled and analyzed. The pre-study at PET-Turbuhaler gave an overview of the work with the current Microsoft Excel-model and its associated problems. The pre-study did also consist of the authors’ own analysis of PET-Turbuhalers capacity model. The literature study was made to investigate how theory advocates the work with capacity forecasting. It showed a difference between theoretical and real capacity. The real capacity is calculated by subtracting the plant’s scheduled and nonscheduled capacity losses (such as time losses for lunch, meetings, set-ups, machine breakdowns and defects from production) from the theoretical capacity. The theoretical capacity of the plant is the capacity when the plant runs 24 hours a day every day of the year. The analysis showed that the current model PET-Turbuhaler use today consist of more or less the same parameters as the literature suggests. The authors could therefore realize that the current model is not necessarily the main problem at this stage. The biggest problem is rather how the current model is being used by the employees. Parameters within the current model are not continuously updated with right data as PET-Turbuhaler thought. The consequence of this is that the long term forecasting is based on out-of-date data even though new and more accurate data is available. The research question can be answered based on the analysis. The most interesting result was the insight that the short term forecasting is not as accurate as PET-Turbuhaler believed. This gives, in order to achieve a good long term forecasting, that PET-Turbuhaler must first improve their short term forecasting by establishing a standardized way of working with the model. Only then can the long term forecasting be accurate. Through discussions regarding the result the authors were able to suggest improvements on how PET-Turbuhaler could work to reach an accurate long term forecast of their production capacity prognosis. The recommendations include continuous evaluation of collected data, regular meetings between production support and production line managers and the benefit of using a sensor, in the end of the production line, to registrate the output rate.

Full textThe overall aim of this thesis is to compare different methods for calculation of Core-Level shifts in metallic alloys. The methods compared are the Initial State model, the Complete screening and the Transition state model. Core-level shifts can give information of chemical bonding and about the electronic structure in solids.
The basic theory used is the so-called Density-Functional-Theory, in conjunction with the Local-Density Approximation and the Coherent-Potential- Approximation. The metallic alloys used are Silver-Palladium, Copper-Palladium, Copper-Gold and Copper-Platinum, all inface-centered-cubic configuration.
The complete screening- and the transition-state model are found to be in better agreement with experimental results than those calculated with the initial state model. This is mainly due to the fact that the two former models includes final-state effects, whereas the last one do not. The screening parameters within the Coherent-Potential approximation are also investigated. It is found that the Screened-Impurity Model can extend the validity of the Coherent-Potential-Approximation and increase it's accuracy.

Full textBackground: In order to increase the efficiency for companies that keep inventory, they need to work with inventory control. Inventory control regards planning and control of the inventory to increase customer and production service. Within inventory control, it is important that companies make decisions regarding the quantity to be ordered and when the order will be added to be available in the warehouse at the right time. Companies can use safety stock to ensure that they can deal with uncertainties in demand and production. Purpose: The purpose of this study is, based on analysis of inventory control theory, to design a theoretical model of inventory control to create an understanding for how the inventory turnover may increase. Furthermore, the theoretical model will be empirically applied to Sandvik's production department of Svedala's current articles to indicate improvements. Method: The study has been made as a case study at Sandvik´s production department in Svedala, based on a developed theoretical model of inventory control. Theory collection to the design of the theoretical model of inventory control has been obtained through professional literature and scientific articles. Empirical data has been collected through interviews and numerical data. Both theory and empirical data have been analyzed from a qualitative approach. Concluding remarks: The designed theoretical model of inventory includes criteria that affect inventory turnover, the steps to implement an ABC classification and various inventory control methods to determine how the placement of orders should be implemented and the amount of safety stock that should be held. The theoretical model vi of inventory control is pedagogical and clear to create an understanding regarding how companies can increase their inventory turnover. The inventory control that was formed for Sandvik´s production department in Svedala, on the basis of the theoretical model of inventory control, consisted of the ordering methods, lot-for-lot, estimated order quantity and cover-time planning. The methods for safety stock were safety stock based on manual assessments and on lead time consumptions. With this control Sandvik´s production department in Svedala, proactively can avoid obsolete and slow moving inventory in the future

Full textMany preschool classes are required to work with a method named Bornholm model to increase the linguistic awareness among children. Research shows that working with children's linguistic awareness in an early stage is of great importance for children's reading skills. With help from the Bornholm model, you work with language games to stimulate the children's linguistic awareness. The aim of the study was to find out how the Bornholm model are being interpreted by active teachers in two municipalities, as well as their thoughts about what different advantages and disadvantages they considered in relation to the method. Furthermore, the results will show if they feel that the method is effective for children's linguistic awareness and development and in what way they feel it is so. The study will also show whether other methods connect to the Bornholm model. Methods of investigation have been interviews with eight informants from two different municipalities as well as questionnaires answered by forty-two informants from two different municipalities. The result shows that the purpose of the Bornholm method in making children become literally aware successfully perceived. The Bornholm method lacks a context integrated in teaching situations, which educators with the right conditions from the municipality and school management succeed in creating through different methods integrated with the Bornholm model.

Full textSyftet med avhandlingen är att öka kunskapen om och förståelsen för hur grupparbete och grupparbetsuppgift konstrueras mellan eleverna. Detta sker genom att skapa en modell, som beskriver det interaktionsmönster och de upplevelser som uppstår när elever försöker hantera sin situation vid grupparbete. Ytterligare ett syfte är att studiens innehåll ska kunna ge underlag för diskussion om hur grupparbete kan användas i skolan. I studien används grounded theory som metodologisk ansats och det teoretiska perspektivet är symbolisk interaktionism. En teoretisk modell – Elevers tillitsskapande i grupp (ETG-modellen) – har konstruerats med hjälp av en observations och intervjustudie i år 7 och 8 på en kommunal grundskola. Modellen beskriver vad som händer när elever med olika social och ämneskunskapsmässig ambition möts i en gruppuppgift och blir ömsesidigt beroende av varandra. När ett grupparbete ska genomföras har eleverna sin egen och de andras ambition, gruppsammansättning och uppgiften att beakta, vilket de har skiftande möjligheter att påverka. De försöker påverka gruppsammansättning och uppgiften för att minska ambitionsdifferensen samt beroendet till andra. Hur de hanterar den kvarstående ambitionsdifferensen via ett tillitsskapande genom att konstruera olika tillvägagångssätt i grupparbetet visas i studien, vilket bidrar till en ökad förståelse av elevernas upplevelse och hanterande av grupparbetsuppgifter. Kunskapen från ETG-modellen kan ha praktisk betydelse när grupparbete som arbetsform används. För att i undervisningen med grupparbete bistå eleverna med deras strävan till att skapa tillit har avhandlingen visat att uppgiften, gruppsammansättningen, och deras olika ambition blir viktiga förutsättningar för detta. Avslutningsvis diskuteras därför lärarens möjligheter att bidra till en samarbetssituation genom att utforma gruppuppgifter, konstruera grupper och sätta mål som skapar samarbetssituationer som eleverna kan uppleva som tillitsfulla.

Full textString theory is a unified framework for general relativity and quantum mechanics, thus being a theory of quantum gravity. In this thesis we discuss various aspects of quantum gravity for particular systems, having in common the existence of horizons. The main motivation is that one major challenge in theoretical physics today is in trying to understanding how time dependent backgrounds, with its resulting horizons and space-like singularities, should be described in a controlled way. One such system of particular importance is our own universe.
We begin by discussing the information puzzle in de Sitter space and consequences thereof. A typical time-scale is encountered, which we interpreted as setting the thermalization time for the system. Then the question of closed time-like curves is discussed in the combined setting where we have a rotating black hole in a Gödel-like universe. This gives a unified picture of what previously was considered as independent systems. The last three projects concerns $c=1$ matrix models and their applications. First in relation to the RR-charged two dimensional type 0A black hole. We calculate the ground state energy on both sides of the duality and find a perfect agreement. Finally, we relate the 0A model at self-dual radius to the topological string on the conifold. We find that an intriguing factorization of the theory previously observed for the topological string is also present in the 0A matrix model.

Full textIntegrating collection and analysis of user data within product development is occurring in companies worldwide and across all industries. User data can provide a company with information about the users which can be utilized to develop existing and new products. This study aims to explore how a combination of user data and other work methods can identify and satisfy customer needs during the development of websites and apps. To answer the research questions a theoretical framework was built from a scientific literature study. The literature study gives much focus to the Kano model to explain the connection between different customer needs and customer satisfaction. Additionally, common user data and other work methods are presented. Subsequently, a qualitative study was conducted at four companies who are working with product development of apps and/or websites. The qualitative study consisted of semi-structured interviews. The results from the qualitative study were analysed and compared to the theoretical framework. After analysis and discussion, the study shows that a combination of user data and other work methods is profitable in a product development process to achieve high customer satisfaction. Furthermore, the study discovers the difficulties in measuring customer satisfaction since customer needs are constantly changing and also because customer satisfaction is often measured on specific product features, not the product as a whole.
