Systemarkitektur för presentation av geografiskinformation- Utredning av Informationssystem och produkter
Banverket Trafik has a responsibility to make sure that the companies who traffic the Swedish railroad have the correct information about the status of the railroad. One of Banverket Trafiks information systems (Opera) presents the train?s actual position on a map and provides the user with physical information about the trains. Due to increasing demands on the information systems, Banverket Trafik needs to update the present system architecture in order to manage the increasing demands on map graphics and map functions. This paper analysis the information system Opera on the basis of theory and support of methods and discuss problems and demands for Opera.
Ekobyn, ett framtida koncept
Jönköping's municipality requested a diploma work witch would present the experiences, as arisen during the existence of the echo village Smeden.To recive information for the background, literature at the university library were searched at the database "Libris" with words like "echo village" and "ecological living".Data was retrieved from 28 questionnaires that were sent out to the inhabitants of the echo village Smeden. The questionnaires contained questions about experiences, opinions, ideas and thoughts about living in this echo village. The results were analyzed and presented by diagrams and tables and showed that the inhabitants where most unsatisfied with the sewer and the system of the toilet. In the opposite the inhabitants experienced that the remaining systems were in satisfactory and the majority of the inhabitants were very pleased with their living conditions.Conclusions of this study are that an echo village would be a suitable alternative to an ordinary living and that ecological living would be something that would work well even in the future. An important thing to remember is that the systems of the households must be easy for the inhabitants to maintain otherwise the environmental thinking would be in risk of failure if some don?t have the energy to manage this properly..
Inhysningssystem för kalvar och ungdjur i större besättningar :
In Sweden, there has been a continuous increase in the volume of housing construction for
dairy cattle. Since 2004, the number of new, rebuilt and extended dairy cow houses undergoing preliminary inspection by the authorities has grown. The livestock farms have mostly focused on cow units instead of calf and heifer sheds; which has led to a need for information in this area. The purpose of the study was to improve advisors? knowledge about bovine building construction and function; to enable them to provide more qualified advice to conventional and organic milk producers who sustain larger herds.
Lotsning som kontroll : En explorativ studie av lotsning från land
Att säkert navigera ett fartyg in till eller ut från en hamn är ett av de svårare momenten inom sjöfarten. För att underlätta uppgiften har man under lång tid använt sig av lotsar ? erfarna sjömän med hög grad av lokalkännedom som assisterar fartygets ordinarie besättning med navigering och andra uppgifter relaterade till en säker passage genom farleden och hamnen.Ny teknik, tillsammans med ekonomiska och säkerhetsmässiga överväganden, har lett fram till frågan om det i någon mån är möjligt att bedriva lotsning från andra platser än från fartyget självt, s.k. fjärrlotsning. Att överföra lotsningsfunktioner från en fartygsbrygga till ett landbaserat kontrollrum är emellertid ingen trivial fråga.
Manöverkrigets förutsättning : En kvalitativ studie om förhållandet mellan praktik och teori
The term maneuver warfare is frequently used in western defense doctrines and theoreticaltextbooks. The ambition of the Swedish armed forces is to attempt maneuver warfare in allappropriate situations. Theories and doctrines indicate the importance of decentralized command and control systems. Mission command (Auftragstaktik) is one such system and should be applied to all situations of the Swedish Armed Forces. There are theoretical and doctrinal bases for warfare and command, but in practice, what are the preconditions for this? Previous research addresses many theoretical questions but there are flaws in existing studies investigating practical realities.The purpose of this study has been to reach a deeper understanding of armed forces ability to maneuver warfare by analyzing conformity of command and leadership perspectives in practice.This is an interview-based qualitative case study in which respondent´s statements were analyzed and interpreted in relation to a theoretical framework.
Kontaktpressningssystem : En studie av elsäkerhet
This work covers a broad analysis of the risks that could impact the achievement of electrical safety of electrical installations. The work includes both electrical equipment such as the installation of electrical equipment.The report illustrates the main technical characteristics of electrical connections greater than 10 mm2 and provides an introduction to the crimping systems for copper and aluminum conductors. In addition to that analyzes the factors that are important to assure the quality of an electrical connection throughout the value stream in terms of both materials such informations. Furthermore analyzed deeper the need for skills development of technicians and other staff.The different parts of this work are analyzed and presented, in theory to studies carried out both at Elpress AB and partly with the help of other scientific reports dealing with similar subjects. In addition, presents a survey that will help understanding the current perception of the electrical connections and cable crimping systems among end users.
Designerrollen i en webbdesignprocess
This study investigates if, and in that case, how design theory is applied in practice in the web development field. Prior research has focused on methods used in the web development field. We wanted to study the designers role in a web design process by comparing existing designer roles with design theory literature. We did qualitative interviews with two practitioners at two different communication agencies in northern Sweden. Based on our qualitative data and literature review we have concluded that a designer has to devote a lot of energy on requirements engineering in order to develop a clear understanding of the design situation..
Modelering av Wideband : Code Division Multiple Access
Today wireless transmission of data is becoming more and more popular and the need for faster transmission rates is increasing. Since the bandwidth is limited it is important to try to use it to the fullest. CDMA is a technology that allows multiple accesses on the same frequency and time thus making it very bandwidth efficient. The CDMA technology was first introduced in the second generation?s cellular systems but has since then been improved and is reused in today?s 3G systems as Wideband CDMA.
Inkongruenta styrmodeller: En fallstudie av reparation och underhåll i ett industriföretag
In theory, the management control of maintenance functions is described as problematic due to the nature of the work performed in the unit. The purpose of this thesis is to examine these predicted problems in practice. Further,the thesis aims at identifying how these control problems may affect the relationships between the maintenance department and its internal customers. A case study has been conducted in one of Sweden?s largest industrial companies to investigate the said control problems in practice.
Den trådlösa massan - svärmbeteende och kollektiv handling
This essay seeks to analyze the consequences of modern information and communication technology for collective action within the framework of social movements. With references to the protests in Seattle 1999, the essay argues that the emergence of distributed collective action is closely related to the use of technology, for example cell phones and Internet. This distributed collective action can be characterized by its decentralized and self-organizing features, forming a global pattern emerging from local interactions. Whereas contemporary theories of collective action can be ´stretched´ to fit these aspects, they lack analytical tools to describe and analyze such systems. Further, their rejection of classical crowd theory is problematic, since it contains valuable insights.
Hydroakustisk kommunikation med bandspridningsteknik
This thesis investigates techniques for stealth hydroacoustic communication using spread spectrum. The Swedish naval defense organisations have a vision that all their units should be able to communicate with each other, even between underwater vehicles. But the properties of water makes it a complex channel to use for wireless communications. Radiomagnetic waves have very limited range in water, therefore acoustic waves are used. In this report the basics of wireless communication systems are described including source coding, channel coding, modulation techniques as well as different techniques for spread spectrum.
Ekonomistyrning i primärvården - En jämförelse mellan privata och offentliga utförare
The aim of this thesis is to analyze and explain the similarities and differences in management control between a private and a public primary care company. A comparative case study was developed based on one public and one private primary care company in Stockholm County Council. The framework of Otley (1999) was used to define and limit the area of management control systems, according to his five factors. For the analysis of the empirical results Hood's (1995) seven doctrines of New Public Management was applied, and customized to fit the purpose of the study. The results indicate that the differences between the two organizations are very limited.
Utveckling av fällbart kartbord för militära ledningsfordon : I samarbete med BAE Systems Hägglunds
I dagsläget finns ett problem med det fällbara kartbord som används i militära ledningsfordon. Större fokus på säkerhet och nya förhållanden har lett till att ett nytt bord behövs som är anpassat för den nya miljön och användarna. Arbetet har utförts i samarbete med BAE Systems Hägglunds och handlar omutvecklingen av ett nytt fällbart kartbord till det bepansrade bandfordonet BvS10 MkII.Utgångspunkten har varit att skapa ett mer användarvänligt bord som dessutom är billigare och väger mindre. Slutresultatet baseras till stor del av energonomianalys där höjd och lutning på bordsskivan analyserades med hjälp av datorsimulerade människor baserade på antropometriska data. Utöver ergonomianalysen har även ett koncept på fällning av bordet samt en hjälpmekanism till denna tagits fram.
