<p>Assignment:</p><p>The mission of the assignment is to map the four return flows with respect to returning volume, weight, frequency, pick up- and delivery points. Today Volvo CE has a lack of information that concerns their own Reverse logistic processes. It is hard for Volvo CE to see where changes need to be done, due to limited reliable sources.</p><p>Purpose:</p><p>The purpose with the study is to make the return flows easier, less expansive and more manageable for both Volvo and their dealers. Further, environmental issues have to be considered in order to find improvements of the returning routines. The analysis is done to bring forth a proposal that will contribute to less unnecessary transports and that also will make it possible to reduce cost.</p><p>Result:</p><p>A couple of improvement areas have been discovered, some of them are radical while others are incremental. The one thing they have in common is to make sure that the return flows are being handled and seen as one common flow rather then separately treated. Among the improvements these are some recommendations to Volvo CE:</p><p>- Appoint special delivery point for warranty returns and make sure that the warranty routines are followed so that unnecessary transports can be reduced. - Store less cores for remanufacturing at the Core Hub. Cores that are not needed are not necessary to transport to the Core Hub. - Make better cost registrations and cost follow ups and evaluate customer satisfaction to be able to find improvement areas in the future.</p>

<p>AbstractThe purpose of this essay is to present a thesis work that has been executed during a period of 10 weeks, as part of a bachelor degree in Graphic Design and Communication and also to present what has led to the design of a sales brochure for the freely distributed lifestyle magazine LKPG. The purpose of the thesis work was to examine the answers to the questions “What does clients and local company owners want to achieve from their advertising in newspapers and magazines?” and “How should a sales brochure for a freely distributed lifestyle magazine be designed to be at most advantage and out of most interest to its clients?”. The work has been carried out through an competitors analysis, qualitative interviews, literature studies and a survey on the target group. The findings of the work are that the market of freely distributed  magazines, both nationally and locally, is extremely wide and has many similar competitors. Although there is still room for all of them, since advertising in newspapers and magazines are highly appreciated and well used. But in order for a magazine to recruit clients on this market, it is most important to distinguish oneself from competitors and offer something special. What has also been stated in this essay is that company owners who advertises in magazines and newspapers in Linköping and Norrköping wants to be treated professionally, be offered smart solutions and also good prices.</p>

<p>As more and more people conduct vigilance-based activities at times other than the traditional daytime work hours, the time utilization will continue to escalate in the next century and will further increase the risks of sleepiness-related accidents.</p><p>This project, which is commissioned by Scania CV AB, is to nvestigate the potential of a method for sleepiness detection belonging to esium AB. Our objective is to examine whether Scania CV AB should continue with the investigation of the patent method, and in that case, which patent parameters, that indicate sleepiness, should be more closely inquired. The purpose with the method of patent is to discover a sleepy driving behaviour. This method is based on the interaction that appears between the driver and the vehicle. The interaction consists of small spontaneous corrections with the steering wheel that in this report is called micro communication. How well the interaction is functioning can be measured in degree of interaction, which shows how well the driver and the truck interact with each other. The interaction between the driver and the vehicle is in this report looked upon as answers and questions with a certain reaction time, which appears with a certain answered question frequency. The differences in the signal’s amplitudes are measured in variation in amplitudes.</p><p>Experiments to collect relevant signals have to be conducted in order to investigate the potential with the method of the patent. It is eligible to collect data from a person falling asleep, which implies experiments conducted in a simulator. The experiments are executed in</p><p>a simulator, one test when they are alert and one when they are sleep deprived. Tests are also executed in a Scania truck. The purpose with these experiments is to collect data of the subject’s normal driving pattern in a truck and to investigate if it is possible to obtain</p><p>acceptable data in a truck.</p><p>The sleepiness experiments have indicated that the micro communication takes place in a frequency range of 0.25 to 6.0 Hz. The variables that have been found to detect sleepiness with high reliability are the reaction time and the degree of interaction presented in spectra.</p><p>The validation experiments have shown it is possible to collect exact and accurate data from the lateral acceleration and the steering wheel torque. But, there is more noise in the signals from truck then there is in the signals from the simulator.</p><p>This method for sleepiness detection has, according to the authors, a great potential. However, more experiments have to be conducted. The authors suggest further sleepiness experiments only conducted during night time. The subjects are sufficiently alert in the beginning of the test to receive data from normal driving behaviour. Physiological measurement could be interesting to have by the side of the subjective assessments as an additional base for comparison.</p>

<p>Computer graphics has long been the foremost area of advancement in both the gaming and the motion picture industry. Nowadays, as computer graphics is getting difficult to advance any further, other areas begin to interest the developers. One of these areas is artificial intelligence. The gaming industry has begun to create far more intelligent virtual characters that no longer are as predictable as they used to be. Mixing character animation with intelligent agents techniques results in a vastly more interesting experience for the gamer as well as for the developer.</p><p>This project focuses on introducing expectational behaviour and trust in intelligent virtual characters. The area is highly interesting as it enables a vastly more complex emotional structure for virtual agents than that of reactive, rational behaviour. Although expectations can indeed be rational, often they are not when it comes to humans. This project studies the effects of expectations on the emotional state of agents and the effect that the emotions have on the reasoning abilities and the action selection mechanism. It also examines how trust influences emotions and vice versa and how trust influences the action selection mechanism.</p><p>One of the requirements of this work is that the computations concerning the triggering of emotions have to be done in real-time. While it is possible to do off-line computations for simulations (such as is often done for the movie industry), it is not what we desire here. It is our goal to create interesting virtual characters that can be interacted with in real-time. Therefore, also expectations and trust must be calculated and managed in real-time.</p>

<p>Arbetet handlar om sjömätning, både hur det går till i dag och hur det gick till förr. Jag har också forskat i alternativa metoder som skulle kunna komplettera konventionell sjömätning.</p><p>Syftet med mitt arbete var att ta reda på hur många oupptäckta grund det finns kvar i den Svenska skärgården.</p><p>Metoden för att få fram bra och trovärdiga uppgifter har varit att intervjua personer som på ett eller annat sätt sysslar med sjömätning. För att kunna beskriva sjömätningens historia har jag tagit hjälp av litteratur.</p><p>Resultatet av min undersökning är att sjökortet i huvudsak stämmer någorlunda med verkligheten. Det finns dock vissa undantag, ofta stämmer sjökortet sämre i skärgårdar där få yrkesfartyg opererar.</p> / <p>This essay is about hydrography, I will investigate how it is done, both today and from a historic perspective. I have also done some research in alternative methods that may complete conventional hydrography. The purpose with this essay was to investigate how many unknown dangerous shoals there is left in the Swedish archipelago.</p><p>The method to receive good and trustworthy information has been to do some interviews to people that in one way or another are practising hydrography.</p><p>To be able to describe the history of hydrography I have had some literature as an aid.</p><p>The result of my investigation is that the nautical chart is mainly comparable to the reality; however, there are some exceptions. The nautical charts is often less reliable in archipelagos were professional shipping is unusual.</p>

This doctoral thesis is about controlling the combustion timing of the combustion concept Homogeneous Charge Compression Ignition, HCCI, by means of variable valve timings. The HCCI research usually is regarded to have started in Japan during the later part of the 1970´s. The world of HCCI has since grown and HCCI is of today researched worldwide. Of particular interest from a Swedish point of view is that Lund Institute of Technology has emerged as one of the world leading HCCI laboratories. The idea with HCCI is to combine the Otto and Diesel engine. As in an Otto engine the charge is premixed but as in a Diesel engine the operation is unthrottled and the compression heat causes the ignition. The combustion that follows the ignition takes place homogeneously and overall lean. The result is ultra low NOx and particulate emissions combined with high total efficiency. A difficulty with the HCCI-concept is that it only works in a narrow area and that there is no direct way to control the Start Of Combustion, SOC. Out of this follows that timing/phasing of the combustion is one of the main difficulties with HCCI combustion concepts. This is particularly emphasized during transient operation and calls for feedback control of the combustion timing. This work investigates one method, the variable valve timing, to achieve feedback control of the combustion phasing. From the work it can be concluded that the variable valve timing can control the combustion phasing during engine transients. In order to improve the performance a non-linear compensation from ignition delay to valve timings has been suggested, incorporated in a control structure and tested in engine test. The engine test has been performed in a single cylinder engine based on a Scania truck engine. The speed range from 500 to 1750 rpm and the load range 1.26 and 10.5 bar of netIMEP has been covered with fair transient performance. / QC 20100629

There are a number of professions in which exposure to life threatening risks is part of daily routine and robots could possibly be used to avoid some of these. In fact, there are applications in which this is already done, the most prominent being bomb disposal and mine clearing. The user testing of new technology is part of achieving similar benefits for other tasks. Methods for use need to be explored, technical solutions have to be trialed, and advantages gained must be compared to the loads imposed in order to guide future development and to determine if the new tools are ready to be deployed. This thesis has performed such feasibility tests on robots within Military Operations in Urban Terrain (MOUT). The aim has been to gain a comprehensive view of a potential user and to embed a robot amongst them in order to assess its tactical feasibility and evaluate its technical performance. An army company specialized in urban operations made up the primary user group and an iRobot Packbot Scout was the robot system in focus. Setting up the tests included identifying and modifying a number of the company’s standard behaviors to include the robot. During the two tests, which lasted over a period of three and six months respectively, it was up to the users to deploy the robot as they considered appropriate. It was found that the military rely on precise and thoroughly trained actions that can be executed with a minimum of ambiguity. Gaining similar efficiency with robots will require tactical optimization over several years. The most common application during the tests was exploration inside buildings in situations where an enemy presence was uncertain and time was not critical. Deploying the robot took more time and was less precise than traditional methods. In return it kept the soldiers out of harm’s way and enabled them to decrease weapon deployment. The range of the radio link, limited video feedback, and the operator control unit were the features constraining the system’s overall performance the most. Other properties, such as the robot’s ruggedness, size, weight, terrain ability and endurance of the robot, on the other hand, proved to match the application. The test unit was of the opinion that robots such as the Packbot Scout would be valuable to have as a standard feature. Four additional users groups were surveyed to examine to what extent the gained results had general validity for high-risk professionals. The most extensive of these included embedding a Packbot into a Special Weapons And Tactics (SWAT) police team for five months. It was found that the robot could be used during negotiation if upgraded with two-way audio. Further technical adaptations would also enable deployment during long term surveillance and for deploying non-lethal weapons. Explosive Ordnance Disposal (EOD), firefighting, and Chemical Biological Radiological and Nuclear Contamination Control (CBRN) were the other groups surveyed. These were investigated by means of interviews and observations during 1-2 days. It was found that while the five professions share many demands they also have unique needs which prevents a single type of robot from being satisfactory for all of them. The tasks within EOD and fire fighting includes grasping and moving objects of up to 50-70 kg. The MOUT, CBRN and SWAT applications are less dependent on the grasping ability, but require a robot that can be easily transported and which is able to access narrows. / QC 20100806

Traditional public transport systems are most often insufficient to provide a good transport service to everyone. Especially, it is not always possible for elderly and disabled persons to use the regular system consisting of timetabled services operating along fixed routes. Normally there is some specific service, often called paratransit, offered to these groups of customers. Such transport services provide better service to these customers, but to a higher cost. This thesis considers planning and evaluation of public transport services that are based on the concept of a dial-a-ride service. This kind of service is suitable for elderly and disabled and often operated as a door-to-door service, where customers are served on demand and rides are coordinated via a call-center. The thesis is divided into two parts. In the first part, a modeling system for simulation of dial-a-ride services is presented. It can be used as a tool to study how different ways of operating a dial-a-ride service, affect the performance and efficiency of the service. This system is used to evaluate how algorithmic changes, based on ruin-and-recreate methods, can improve the replanning of already inserted requests, and thereby improve the scheduling. The modeling system is also used to examine the effects of using zone-based distance estimates instead of true, address-based, distances when computing the schedules. The results show that only small differences are found.The second part of the thesis concerns an extension to dial-a-ride services. By combining a dial-a-ride service with a fixed route service, an integrated dial-a-ride service is created, where some part of each journey may be carried out by the fixed route service. An exact mathematical formulation of this problem is presented and it is shown that the formulation is strengthened by valid inequalities, variable substitution and subtour elimination constraints. Simulations of an integrated service are also performed to analyze and evaluate how the attractiveness and operating costs of the service depend on how the demand responsive service is operated.
