Det mindre företagets räddning? : en studie om hur ekonomisk brottslighet kan undvikas genom en intern kontroll
The purpose of this essay was to examine whether small businesses can avoid ac-counting crimes with a well-conducted internal control system. The questions we asked ourselves was, whether and if so, companies can prevent this from happening by using a internal control.In this essay we used a qualitative approach. Essential information was given to us from four different interviewees. We also worked from an inductive approach which means that we interviewed people without any earlier research to build on. The method also had a hermeneutical approach, which means that we made different interpretations based on the reference framework and the empirics.After the study had been carried out, we concluded that all evidence from this essay suggested that even small businesses need an internal control to protect their business.
Utveckling av modellbaserad reglering i kommersiella styrsystem
In industrial control systems PID-control remains the prevalent strategy, also for processes that would benefit from model based control. The purpose of this thesis is to evaluate whether model based control can be readily implemented in an industrial control system. To this end a simulated surge tank with a simulated industrial control system is studied. For evaluation two scenarios with specified objectives are selected.Following a review of LQR and versions of MPC, Predictive Functional Control (PFC) is considered the most suitable for implementation. PFC is a form of MPC developed with industrial applications in mind and therefore has several advantages for implementation in an industrial control system.
Skiftarbetets påverkan på den upplevda stressen : - en undersökning inom vården
AbstractThe purpose with this study was to get knowledge if there are any possible differences in, and correlation between, experienced stress, experienced demands, experienced control and experienced social support in correlation to shiftwork.The study was made at two central hospitals in south of Sweden and had 90 participants (78 women and 12 men) that answered a questionnaire in the current variables. The result in experienced stress showed that there were no differences between shift workers. The results showed a difference between the day- and the nightshift in the correlation between control and stress. The writers speculates that the reason why the nightshift experience high stressvalues with high control can depend on the lack of presence by higher managers, compared with the dayshift. .
Samverkande, motverkande eller kompletterande? : En uppsats om relationer mellan styrsystem
Title: Co-operative, prevent or complement? - An essay on the relationships between control systems. Authors: Kim Eriksson and Victoria KarlssonPurpose: The essay aims to describe the relations between control systems and how they related to each other, based on an operationalization of the control systems. Research question: What are the control systems relations to each other? With regards whether control systems co-operative, prevents and/or complement each other.Theoretical framework: The essays theoretical framework is based on Malmi and Browns (2008) description of five different control systems and control mechanisms associated with each control system.

KRAV OCH MÖJLIGHETER FÖR STYRNING AV VATTENFALLS VATTENKRAFTSTATIONER
The secondary control must be part of the production plan, since the capacity will bedeployed in advance, just as the primary control. The activation of the new frequencycontrol should be preformed in Vattenfall's operations centers (DC) to minimizecommunication delay. Vattenfall needs to work towards a more holistic optimizationsystem. The main issue for Vattenfall Generation is not how we produce but ratherwhen, which is done with creation of bids. This is where there is the mostopportunity for improvement.
Effekten av syskonplacering på Health Locus of Control : En studie om syskonplacering och kön kan relateras med locus of control ur ett hälsoperspektiv
Studier har visat att det finns ett samband mellan syskonplacering och locus of control, medan andra studier inte funnit något samband. Syftet med denna studie är att undersöka relationen mellan syskonplacering, kön och locus of control ur ett hälsoperspektiv hos gymnasieelever i årskurs 3. I undersökningen deltog 147 gymnasielever ifrån fem skolor i Kronobergs län. Resultatet visade att kön och syskonplacering samvarierade med intern health locus of control (F= 3,01;p< 0,03; ES= 6,2) och att syskonplacering och kön tillsammans inte visade någon signifikant inverkan på extern health locus of control (F= 2,20;p=<0,09; ES= 4,6). Fyndet kan indikera att manliga mellanbarn i större utsträckning strävar efter en intern health locus of control än kvinnliga mellanbarn.Nyckelord: Syskonplacering, health locus of control, intern- och extern locus of control, kön..
Utveckling av styrsystem för EMC-kammare
This thesis aims to develop a control system for measuring electromagnetic compability (EMC). This has meant that a controller designed around an ATmega8 microcontroller has been manufactured and programmed. It has also meant the development of a comprehensive control software in the program MATLAB. The control system has been tested with satisfactory results and can now, monitor and control measurements of the EMC-type..

Att vårda en person som drabbats av stroke : Anhörigas upplevelser
Background: Each year approximately 30 000 people suffer from stroke in Sweden, often with substantial mental and physical consequences. Those who suffered from stroke handled the situation by mourning what they had lost and by accepting their changed body and life situation. For those who provide care for people who has suffered a stroke help and support was required. The caring science perspective was based upon caring and suffering. Aim: The purpose of this study was to describe family caregivers? experiences of caring for persons who had suffered a stroke.

Laglig rätt men på olika sätt
I have investigated how municipalities support children with ADHD. I have interviewed persons responsible in five different municipalities. The persons have had the authority to decide how the support funds are to be shared in the municipality. Mostly I was interested to know if the support was the same in all these municipalities and if the children with ADHD really got the help and support they were entitled to. I discovered that the support varied; in some the children were correctly diagnosed but in others municipalities I was not convince.
Adaptiv temperaturreglering av bostadshus
The control of indoor temperature must be able to handle large time constants and both measureable disturbances like outdoor temperature, and non-measurable disturbances, like waste heat from appliances. Due to cheaper microcontrollers (small computers with designated tasks) with better performance, more advanced and computation-demanding methods for control can be used.In this thesis, Generalized Predictive Control (GPC) has been implemented and tested on a theoretically derived model of a house. GPC states that a model of the system is estimated in every sample, and the control is carried out simultaneously, based on predictions of the model. Disturbances like solar radiation can be estimated and used in the control as well. The control signals are determined by quadratic programming, which makes it possible to consider conditions, for example limitations on the control signals.GPC requires a number of parameters to be defined, like model order and control signal penalty, but is relatively robust for variations in them.
Skolan, en arbetsplats att trivas på! : en studie om framgångsrika skolledares syn på lärares psykiska hälsa
Aim and questionsThe aim of our study was to increase knowledge about successful school managers' views on teachers' mental health and their own work regarding this subject.In what ways do the school manager work preventive with measures on teachers' mental health? How does leadership affects teachers' mental health? What factors create mental health among teachers? MethodIn order to answer the questions, we have chosen to use semi-structured interviews. To get in touch with schools that have been successful with their work with the teacher's mental health, we have made a targeted step wise sample where we contacted the primary managers of six randomly selected municipalities in Stockholms län. In total six school managers have been interviewed. The empiric data were thematized and analyzed based on the demand-control-support model. ResultsAll the interviewed school managers agreed to that the concept of mental health is about feeling good, about balance in life and to feel safe.
Projektering av passersystem : En studie i användarstöd vid offertarbete för ARX passersystem
To have a tool that guides you when you work with a complex system can be helpful since the complexity of the work can be reduced. In this thesis I explore the possibilities to use a helper application whilst planning installations of access control systems. The purpose of the application is to provide support during the planning and at the same time make the user aware of the limitations that exist in the access control system ARX Access. By combining early user input and the theory of formativity, the result became an application written in Java..
