Distribuerade fastighetsautomationssystem : - En implementation av kommunikationsprotokollet BACnet
Building Automation Systems in commercial buildings are often designed and installed by different contractors, using equipment and components from different manufacturers. The lack of an accepted communication standard has resulted in a few different standards. Many manufacturers of building automation systems only support one, a few or none of these standards, while developing proprietary system solutions. Regin, who develop such equipment, are planning to adopt an open communication protocol specially designed for building automation - BACnet. As a step in that direction this thesis was announced with the purpose to investigate the possibility to implement BACnet in one of their products and to gain more knowledge of the BACnet protocol.
XML som informationsbärare för EDI
Information handling has been a key issue for different companies for a long time. Electronic Data Interchange (EDI) is used to transfer different business documents from one company to another. This is done in such way that the information itself is separated from how this information is stored and handled in the companies internal systems. As different companies have different systems there is a need for a standardised format for this exchange. There is a big difference between EDI-systems based on what kind of EDI-standard is used.
Grafisk skärpa : ett arbete om gaturummet
The streetscape is a complex environment with a lot of different parts and users.
If you look at the streetscapes main parts you have floor, walls, roof and
furniture. The floor in the streetscape, the street, consists of the ground and the
paving. It can be made of a lot of different materials with both architectonic
and practical functions. The walls usually consist of the houses. They have a big
influence on the streetscape depending on architecture, heights and widths.
Augmented Reality i mobiltelefonen : En kunskapssammanställning med trafikinriktning
This master thesis is about Augmented Reality (AR), a phenomenon that has existed since the mid-fifties but only recently has become available for the general public. This report is a knowledge compilation about AR, focusing on AR in cell phones and the use of the technology in traffic related situations.AR is usually described as adding a digital layer of information onto the real world. There are different technologies to make virtual images; in cell phones sensor-based and camera-based technologies are the most common ones.In this report, the market of AR applications for cell phones has been investigated. Three use cases have also been investigated in order to get more knowledge about the designers' thoughts and visions.In order to analyze the technology and the applications in a broader and more scientific perspective, two theories has been used: Situation Awareness (SA) and the Service Dominant Logic (SDL). These theories seem useful when reflecting on the Swedish road administrations vision, and to investigate what the applications and the AR technology can contribute to the traffic domain.The conclusions of this thesis are that:- AR can be applied on most of the human senses, but augmenting by visualization is most common.- The market for cell phone applications is growing rapidly: AR applications are relatively new but on the rise.
Transporter för hållbar utveckling : En optimering av utsläppsberäkningarna inom Coop
Man?s impact on the environment is something that increasingly becomes topical in today?s society. Because of this, several companies have started to take interest in the effects they?re responsible for, not least considering their image. Emissions of carbon dioxide generated from goods traffic are accountable for a large part of the total emissions of greenhouse gases in the world.
Deriving ECA-rules from timed-automata specifications.
Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.
Alternativ för värme- och kylaförsörjning i planerade kontorsbyggnader på Arlanda
This thesis consider alternatives for heating and cooling planned office buildings at Arlanda airport. The thesis is divided into three parts where the third part is a shorter synthesis of the two first. In the first part the energy demands of the buildings are modelled in a computer program. Two different building models are created, one more conventional and one with good energy properties. The results shows that with proper construction and ventilation systems etc.
Införande av spårvägar i Örebro - Förslag till spårvägssträckning
In Örebro, the car traffic share does not tend to decrease. The crowdedness on some of the bus routes is high at times. Investigations show that the residents of Örebro want a city centre whose street environment is more restrictive of car traffic and better for pedestrians, cyclists and public transport. To decrease the car traffic share a rapid, convenient, clear, effective and environmental friendly public transport with high frequency and strong capacity in a short, direct and logical network is needed. A modern tramway fulfils these criteria.At first, this report describes factors that are important to take into consideration when planning a tramway.
Distribuerade Kontrollsystem för Smarta Elnät Baserat på Raspberry Pi
Artikelns fokus ligger på smarta elnät och specifikt den distribuerade kontrollen av dem. Syftet med projektet var skapa hårdvaran och mjukvaran till ett distribuerat informations- och kontrollsystem för att kunna styra lasterna till en liten elnätsmodell, ICS byn (Industrial Information and Control Systems). Speciellt så skulle det undersökas om det var möjligt att skapa ett fungerande kontrollsystem med billiga kommersiella produkter, Raspberry Pi:s och Arduinos. Projektets resultat kommer sedan att användas för ett fortsatt utvecklingsarbete på ICS.För att skapa det distribuerade kontrollsystemet så användes JACK Intelligent Agents, en utvecklings miljö för multiagent system baserat åa Java. Rapporten tar upp de olika hårdvarukomponenterna Arduino, en mikrokontroller och Raspberry Pi, en linuxbaserad dator och transistorkretsarna som har byggts för att kunna driva de elektromekaniska brytarna i byn från Arduinon.
Utveckling av ett hjälpmedel för träning och utvärdering av förare av tunga fordon
The purpose of this master thesis is to evaluate how internal vehicle information inScania buses and trucks can be used for evaluation of driver performance regardingfuel economy, vehicle wear, traffic safety, emissions and cargo damage. To someextent it was examined whether this information could be used for training the driverto a better driving style. In addition, a prototype for such a system was developed.By first defining what distinguishes a talented driver and how he/she differs from apoor driver, followed by a study of the internal vehicle communication, a system thatin real-time gathers and interprets vehicle data could be developed.The resulting system can with reasonably high reliability detect a number of trafficevents (such as braking, lane changing or hilltops). At each such event, the driver?sbehaviour can be evaluated.
Hantering av informationssystem
Lund who has over 90 systems in 12 departments and now wants to streamline the management of these IT systems. Governance of IT systems is something that Lund would treat as it carried a large amount of changes in their practices, where the control is something missed in trying to standardize their systems. What's missing for Lund Municipality is routine to fall back on in order to streamline the management when they get into these complex situations.Given that Lund treat so many systems make it so that the situation quickly becomes very complex due of the organization's structure. The municipality is divided into twelve departments that have their own goals, it is an organization that is organized, which makes creating standards become complicated when all departments have different needs. Our study was based on a framework that deals with complex environments that lack a clear definition.An analysis was conducted where we started from the theory associated with the interviews conducted in which we aimed to understand their decision and understand the processes that affect system development.
Cirkulationsplatser ? estetik och design :
The purpose with this final thesis has been to study the aesthetics and design of roundabouts and to ascertain important factors that influence the experience of them. The investigation was carried out through literature-, field studies and interviews with persons that in different ways have participated in the formation of roundabouts. Furthermore, six roundabouts have been explored in more depth so that the survey would get a more practical link. These six roundabouts all occur in the rim of a city and do thereby have an important role as a gateway. The environments in such contexts are often complex which adds additional difficulty in achieving a visually appealing design, especially when taking into account the usually high traffic intensity.
Bedömning av området energi : En jämförelse mellan Miljöbyggnad, Svanen, FEBY12 och PHI
The Swedish building and property management sector are responsible for about 30 % of the total energy use. In order to take environmental consideration, different environmental assessment tools and standards are used. Miljo?byggnad, Svanen, FEBY12 and PHI are some of these. There has been increased interest to certify buildings and therefore it is of interest to evaluate the assessment of the energy field to see if relevant energy aspects are assessed.
Klassifikationssystem på webben: Traditionella och nya
The aim of this thesis is to investigate the opportunities of classification of web pages. Two classification systems are compared; a library classification system traditional and a system that is developed for use on the web new. UDC is chosen to represent the traditional systems, and Yahoo! represents a so called new system. UDC is used by NISS Directory of networked resources, which is a directory that uses the system for organisation of electronic resources. Both systems are analysed from two different perspectives, a multidisciplinary and a timeperspective.
Installation av övervakningssytem ombord på fartyget M/S Andromeda
This report is regarding an electrical installation of an alarm system on a post fishingboat called Andromeda. The background of the installation was an earlier andinadequate alarm system that led to a motor failure. The ship was taken out of serviceand was sold to Björn Magndahl who rebuilt it to a yacht.The project was conducted partly by developing the existing systems, partly bydocumenting the work by means of electrical blue prints. Except the alarm systems, aninstallation of the frequency control unit for the bow thruster was installed.The installation was working fine and the outcome of the documentation was handedover in a form of a binder during the test drive of the systems and the assignment wasapproved..
