In this study we have examined the possible quality standards and methods for applications with service workshops in the forest industry. The purpose of the methods presented here was to start the work of standarardising the maintenance service in the industry and be of use for service providers in their quality effort.The methods we used to accomplish the study were interviews and field visits together with a comprehensive literature research. Our results are presented in the form of four solution proposals: a standard based on existing SIS standards for terminology and key indicators, checklists that are filled in by mechanics with customer participation, the construction of a instructions database, and the implementation of the method 5s.We believe our suggestions can help the service providers in the four problem areas that we have identified: long term strategy, documentation, recruitment of competent technicians, and standard procedures in their operations. These improvements will be beneficial for both the service provider and the customer..

The purpose of this thesis was to create a communication interface which insures that all the right hardware is in its right place in the IS-node before Ericsson AB delivers it to their customers. One of the first parts of this work was to make sure it is possible to create such an interface for IS. This thesis then explains how to construct an interface that retrieves information from the IS-node into a C#-application. One important part of this project was to collect information and transform it to an XML output with the purpose of then being used in other applications in the future. The application created within the scope of the thesis exports the information retrieved from the IS-node in an XML-file or a text-file.

The purpose of this paper is to investigate the possibility of replacing data from highspeed filming (Qualisys motion capture) with data from Inertial Measurement Units (X-io technologies), when used to run a model of torso and pelvis in OpenSim. Qualisys motion capture data is used as the golden standard to validate the result visually and with Bland-Altman plots.In order to obtain comparable data experiments are conducted where both methods of collecting data are used simultaneously. Data from the IMU's then need to be processed in Matlab before it can be used to run the OpenSim modell. Several Matlab programs rotate the IMU data to a static reference frame, filter and integrate it, then create viritual markers that correspond to Qualisys' optical markers.The conclusion is that using IMU as a method for collecting data can replace Qualisys in some applications, but not in ones that require high precision. However, this paper only begins the examination of IMU's and there are most likely improvements to be made..

Certifications is common for IT in relation to individual program languages or program applications. Certifications for educations that endures several years is not as common to see. In this paper the situation for the Systems Science programme is researched, by investigating how the programme looks around in Sweden. Also by using interviews, show how companies and people responsible for the programme in Umeå, think the contact is between them and how the knowledge of the Systems Science students are from the view of the companies that employ them. In the end the conclusions show that there are differences in the Systems Science programme, and that the companies have quite a similar view of what the Systems Science students are good and not so good at.

Mobile application demands a lot of attending to the program code. There are lots of different development platforms that can be used for development. Not only for the specific operating system there are also lots of different cross-platforms that should minimize the amount of program code. This report is comparing the way of creating an android application in the cross platform Xamarin versus in the platform Eclipse using the Android plugin. It contains a part about the architecture of Android and its functions.

In this project an iPhone application for storing food and drink experiences was developed with focus on an easy interaction design. The already existing market of similar applications were studied and evaluated to extract their positive and negative features. Interviews with experts within the food and drink business where made in the pre study to get a good perception of how to divide and categorize the sections in the application. To optimize the usability, workshops with potential users with different technical experiences where continuously held during the development of the design.During the development two variants of development environments where evaluated. The final result of the application was developed in the environment that made the best impression and seemed to be the best alternative.The resulting product has a thought out design meant to be easy to understand, even for the first time users.

This report treats a Master Thesis performed at Scania CV AB. The task was to create a computer model of a hydraulic actuator system in the software AVL Hydsim. The system consists of two spring-loaded masses with surrounding hydraulic components. The purpose of the model is to study phenomenon and problems in the system, as well as to be a support in the development of the system. It is not supposed to be used to study absolute values in its current form.

The result of this master thesis report describes the advantages and the drawbacks that will arise when implementing an Ethernet based intercommunication system in military vehicles. The report presents a possible solution and describes how different sound applications will be implemented into the suggested solution. The report show that IP LAN in vehicles leads to more advantages than drawbacks. The main advantages are that all kind of media can share the same LAN and that there is a lot of knowledge of this technique in the civil area. The main drawback is about delay.

The eld of Brain-computer interfaces (BCI) concerns linking together an external device with the brain of a human or an animal. By doing this the conventional use of a mouse or keyboard can be circumvented, which can greatly benefit people with different types of diseases that cause paralysis or other loss of motor control, such as Amyotrophic lateral sclerosis (ALS). A BCI can also be used for cognitive training of either healthy or mentally impaired subjects to increase cognitive capabilities.In this thesis an implementation of an interface is made against such a device, the Emotiv EPOC Headset. The result is meant to be a stable basis for further study using the device. An in-depth study of the history of EEG and its current use in clinical work and research in the topics of BCI as well as Human-computer interaction (HCI) is presented.

Utvecklingen på den teknologiska marknaden har kommit att påverka företag i en allt större utsträckning då marknadsföring på Internet blivit allt viktigare. Den ökade använd-ningen av smartphones har bidragit till att fler och fler människor ständigt är uppkopp-lade vilket i sin tur har öppnat upp för nya sätt för företag att skapa relationer och att inte-ragera med sina kunder. En bidragande faktor är sociala medier som har öppnat upp för interaktion där företag och kunder kan kommunicera med varandra. De har även öppnat upp för kommunikation kunder emellan, vilket både skapar positiv och negativ word of mouth. I takt med utvecklingen av den nya telefonin, har mobilapplikationer kommit att få en allt större betydelse som marknadsföringskanal.
