En studie av rörelsen mot en processorienterad sjukvårdsorganisation - eller hur man får upp strutsar ur sanden
Health care costs in relation to GDP are escalating all over Europe and the Swedish health care industry is not an exception. Between 30 and 50 percent of resources used in health care are considered waste, in the sense that they don't contribute to increased health. This illustrates the big need for hospitals to become more efficient which is why many hospitals today are trying to move towards a process-oriented organization. This paper therefore aims to identify the elements necessary for this type of organizational change, the barriers encountered when moving from a functional to process oriented hospital as well as how to overcome them. The case study was conducted at Karolinska Universitetssjukhuset and shows the importance of not just transmitting a sense of urgency but also communicating that the upcoming change is long term.
Aktiesammanställare med teknisk analys och simulation
Websites today only offer simpler form of technical analysis and are not fun to use, therefore student decided to build a website that makes technical analysis a bit more fun by giving user possibility to experiment with settings for technical indicators and also see clear visible results from analysis. Student decided to build website in ASP.NET. Technical indicators for this project only consist of those who give buy and sell-signals via cross-over, no divergence or pattern finding.This project has three questions that define this project. It?s important that there is good functionality so that performing an analysis is perceived as simple, one question is therefore; what functionality for website is needed in order for analysis to be perceived as more simple?Technical analysis is a pretty complex subject and demands an interface that is perceived as easy to understand and easy to use, it?s therefore important that the interface is well designed, second question is therefore; how should the interface be designed to be user-friendly?When systems grow large they often become hard to develop and later on unmaintainable because of the accumulated complexity and dependency between classes, the code is a mess, the last question is therefore; how can the systems complexity be eased with object-oriented design principles?Jakob Nielsens ten heuristics for User Interface Design were used as inspiration for designing the interface for the website.
Studie av planerings- och produktionsprocess i sågverksbranschen
The sawmill industry is a relative fragmented industry that is in an economic upswing andwith a hard competition. The customers have high demands on their suppliers and the highcustomer demand make it necessary for the companies to make a streamlining in planningand production. For that reason it is very important that the planning- and productionprocesses aren?t to complex and with a simple structure.The purpose of this report is to study and map out a marked out part of a planning- andproduction process, from adjust works to final delivery, at a company in the sawmill industry.Different methods have been used for the report, among others interviews and subordinatedmaterial.We have mapped out a marked out part of the planning- and production process at theCompany. This part we have studied, and we have analysed the process it self and otherthings connected to the process.We see the planning- and production process in the Company as complex.
A Strategic Decision-Making Model for Supply Chain - A Void to be Filled
Many researchers emphasize the increasing strategic importance of supply chain management, but there is still a lack of concrete guidance for managers faced with strategic decisions in supply chain. Within decision-making theories, the rational decision-making model is the most commonly used. This because of its suitable foundation, enabling a structure to the complex decision process. The rational decision-making model is today not developed to include the aspects of strategic decision-making made in supply chain. The purpose of this research is to adjust a structured rational decision-making model, making it applicable for strategic decision-making in supply chain.
Aktiv bullerdämpning i ventilationssystem
Active headsets have been on the market for years and now it is time for something else to enter the stage. The technology of active noise reduction can for exmple also be used in ventilation systems for reducing ventilation noise. An active control system principally consists of four important components, namely the downstream error microphone, the upstream detection or reference microphone, the digital signal processor (DSP) and a loudspeaker. The upstream reference microphone listen to the primary ventilation noise and sends it to the DSP which makes a phase shift to the signal and sends it to the loudspeaker. The loudspeaker sends out the opposite waveform of the incoming one and reduce the primary ventilation noise.
Europeiska r?dets gestaltning av klimatkrisen: En empirisk unders?kning av Europeiska r?dets inramning av klimatkrisen under ?ren 2019?2024
This paper aims to deepen the understanding of how the European Council frames the climate
crisis and its implications for political legitimacy and policymaking. The climate crisis is one
of the most pressing challenges of our time, influencing not only environmental systems but
also societal structures and governance. By analyzing the European Council?s framings during
the 2019?2024 strategic agenda, this research investigates how political actors shape
narratives to justify actions and policies in response to the climate crisis. Through a discourse
analysis of official Council conclusions, using a framework drawing on six typologies of
framing, the research examines the Council's evolving narrative in the context of multiple
crises, including the COVID-19 pandemic and the war in Ukraine.
Bonusregn över svenska storbanker : En studie om belöningssystemens utformande för legitimitet
The current financial crisis has left its mark. It has even hit the major Swedish banks who have shown large losses. The media has not been slow to take note of this, and the constant political debate about the bonus culture has been reinvigorated. Our aim is to find out how the major Swedish banks relate to the publicity and describe how and why senior executives are rewarded, and what strategies banks are using in the design of their reward system to maintain a legitimate behavior, and thus the confidence of its stakeholders.As a starting point to answer our purpose we have used the agency theory that describes our view of how various problems occurs and how incentives can be established in order to get senior executives to act for their owners' interests. Modern theories of reward systems are taken from a variety of authors, these theories give us an insight into how reward systems can be designed in banks.
Diagnos av stiktion i reglerventiler för prediktivt underhåll
This master thesis reviews advances in detection and diagnosis of static friction (stiction) in control valves. Control valves suffering from stiction results in oscillating control loops which in turn decreases both the process stability and reliability. Perstorp AB sees a necessity to automatically detect stiction in valves before the effects of the malfunctioning valves have become too severe. This thesis presents an introduction to maintenance, control loops and how stiction in valves can affect performance of control loops.A selection of methods presented in the literature are introduced and examined using normal operating data from the site in Perstorp. Common for all selected methods is their intuitive ideas and that they are based on normal operating data and minimum amount of process knowledge.
Diagnostiksystem i gaffeltruckar
This is a final thesis done at BT, considering one of their forklift truck models called Reflex. The first part of this report is about a preliminary investigation investigating what kind of diagnostic systems BTwants to use, and also which demands there are to meet all expectations on such system. Secondly a diagnostic system, which will show if the drive wheel is worn out, will be presented. In the preliminary investigation, two kinds of diagnostic systems were mentioned. These were Model based diagnosis and Predictive analysis.
För en kreativ arbetsplats: Kvinnor + Män = Sant - En fallstudie av Enea Systems AB
Syftet med vår undersökning är att ge förslag på vad ansvariga på mansdominerade företag bör tänka på vid utformningen av sin interna- och externa kommunikation samt hur dessa kan samverka då mansdominerade företag önskar attrahera fler kvinnliga medarbetare.Vi har valt att använda oss av relevanta teorier som kopplar samman marknadskommunikation (intern- och extern kommunikation), rekrytering (att attrahera) och mångfald (genus). Relevanta delar av dessa teorier har använts vid analys av vårt empiriska material.Vår empiri utgörs av intervjuer med sju medarbetare på Enea Systems AB samt observation av Enea Systems AB under arbetsmarknadsdagar på Lunds Tekniska Högskola. Slutsats: Det är viktigt att ha en förståelse för hur intern- och extern kommunikation hänger samman i ett system. Det som kommuniceras internt speglas även utåt. Det är därför viktigt att förstå hela flödet av kommunikation, som finns både internt och externt för att mansdominerade företag skall lyckas attrahera fler kvinnliga medarbetare.

Rekommendationssystem för interaktiva musiktjänster : en utredning av aktuella trender och attityder gentemot framtidens rekommendationssystem diskuterat ur forskar-, industri- & användarperspektiv
Parallel to new technological advancements, including the development of interactive recommender systems, digital music services on the Internet, such as Spotify, have in a short time span gradually replaced former physical media such as CDs and MP3-players and become pioneers on a market with an otherwise uncertain future. By subscribing to the service, users have access to a vast library of music and from any device with Internet access. In order to provide a satisfactory and useful musical experience, different ways of coping with the vastness is required - which is precisely what recommender systems are for. Improved filtering techniques and use of devices built in sensors, make way for new opportunities of more precise and contextually tailored suggestions for track selection, which in turn leads to potential privacy issues when using interactive music services. But where do we stand today? By compiling, exemplifying and discussing three different perspectives with relating to the development of interactive music recommender systems, the objective for this paper is to provide a for science, industry and user, objectively nuanced account of current potentials and expectations.
Premiepensionens Marknadsrisk : En Monte Carlo-simulering av den allmänna pensionen
A reforming trend is captured showing that countries are shifting from defined benefit pension systems towards defined contribution systems. The reforms have been justified through predictions that the defined benefit systems will not manage to provide good enough pensions to members in the future. The newer defined contribution pension plans often include individual financial accounts where individuals have the possibility to choose how a part of their pension savings should be invested. Sweden was early to introduce such a system, which at the moment provides more than 800 funds to choose from. The aim of this thesis is to capture the market risk associated with these individual investments and does so by using Monte Carlo simulations for six selected pension funds.
