SAAB has a project under development for a network system with connected nodes, where the nodes are both information consumer and producer of different communication types. A node is an equipment or an object that are used by the army e.g. it can be a soldier, military hospital or an UAV. The nodes function as a part of a mission e.g. a mission can be Defend Gotland. The aim of this project is that the user will rank different missions from the one with the highest priority to the lowest. This will affect the network in a way that the communication between the nodes at the mission with the highest rank will be prioritised over the communication between the underlying missions. A user can via the GUI rank the missions, and then set the associated settings for them. Via the GUI the user should be able to work at three different levels. The first is to plan upcoming missions. The second one is in real time see if the system delivers the desired conditions. The last one is to simulate if the system can deliver the desired conditions. This thesis investigated various HCI models that could be used to create a GUI, to reduce the risk of a user configuring the system incorrectly. The study showed that there are no HCI models that take account for misconfigurations, and therefore a new model was created. The new model was used and evaluated by creating a prototype of a GUI for SAAB’s project and was tested on a potential user. The test showed that the new model reduced the risk of misconfigurations. / SAAB har ett projekt för utveckling av ett nätverkssystem med anslutande noder, med noder som kan vara både informationsproducent och konsument för olika kommunikationstyper. En nod är en sak eller ett objekt inom försvaret t.ex. kan det vara en soldat, militärt sjukhus eller en obemannad farkost. Varje nod tillhör ett uppdrag, tex att försvara Gotland. Målet med projektet är att man ska kunna gradera de olika uppdragen och därmed gradera vilken prioritet dessa noder har i nätet. Noder som tillhör ett uppdrag med hög gradering kommer prioriteras över de underliggande uppdragen i nätverket. En användare kan via ett grafiskt användargränssnitt gradera uppdragen och konfigurera tillhörande inställningar. Via det grafiska användargränssnittet kan en användare även planera, gradera och konfigurera inställningar för kommande uppdrag samt simulera om det går att genomföra. Användaren ska även i realtid kunna se om de önskade inställningarna inte kan leva upp till de önskade kraven, och därmed kunna åtgärda detta.  Detta arbete undersökte olika MMI-modeller som kan användas för att skapa ett grafiskt användargränssnitt som minimerar risken att användaren konfigurerar systemet på ett felaktigt sätt. Studien visade sig att det inte finns några MMI modeller som tar hänsyn till felkonfigureringar, och en ny modell skapades. Den nya modellen användes och utvärderas genom att skapa en prototyp av ett grafiskt användargränssnitt för SAAB:s projekt, som testades på en potentiell användare. Testet visade att den nya modellen minskar risken för felkonfigureringar.

Ce mémoire est une description et une analyse de la mise en scène dans trois films screenlife – Unfriended (Leo Gabriadze, 2014), Unfriended: Dark Web (Stephen Susco, 2018) et Searching (Aneesh Chaganty, 2018) – qui est principalement défini par les interfaces utilisateur graphiques (IUG) affichées dans les représentations des enregistrements d'écran d'ordinateur par lesquels ces films sont définis. Le but de cette étude était de découvrir – en utilisant la recherche sur les IUG par Lev Manovich et Anne Friedberg – comment la nature modulaire des médias numériques – vidéo, photo et texte – positionnés à l'intérieur de chaque IUG permet de transposer certaines conventions cinématographiques, techniques de narration et de roman policier sur les IUG. La recherche révèle qu'en raison des IUG (associées au système d'exploitation et à des applications), certaines traditions narratives ont été présentées de manière multiple, simultanée et superposée dans la mise en scène, par opposition à la manière singulière et séquentielle que les films ont généralement représenté le temps et l'espace en montrant un plan à la fois. Le premier chapitre raconte l'histoire du film screenlife et comment il a connu plusieurs itérations en raison de ce qui avait pu être affiché dans les IUG à différentes périodes entre 2002 et 2018, notamment les types d'appels vidéo, de sites Web et de médias sociaux. Le deuxième chapitre propose une mise en scène screenlife qui divise l'espace de l'écran en trois niveaux pour articuler comment les traditions cinématographiques et narratives ont été transposées dans Unfriended, Unfriended: Dark Web et Searching. Le troisième chapitre est une continuation de ce processus, mais avec un accent sur les techniques de roman policier, les indices et les fausses pistes, présents dans chacun de ces trois films screenlife. La description et l'analyse confirment que ces traditions de mystification sont également transposées dans les IUG de manière multiple, simultanée et superposée à partir de la manière singulière et séquentielle dont elles ont été présentées dans les romans policiers et les films policiers traditionnellement tournés. / This master’s thesis is a description and analysis of the mise en scène in three screenlife films – Unfriended (Leo Gabriadze, 2014), Unfriended: Dark Web (Stephen Susco, 2018) and Searching (Aneesh Chaganty, 2018) – that is primarily defined by the graphical user interfaces (GUIs) displayed within the representations of computer screen recordings these films (and this format) are defined by. The purpose of this study was to find out – using the research into GUIs by Lev Manovich and Anne Friedberg as a framework to interpret the space within a computer screen – how the modular nature of individual digital media – video, photo and text – positioned within each GUI permit certain cinematic conventions, storytelling and mystery fiction techniques to be transposed onto a computer screen’s interfaces (GUIs). The research reveals that due to the GUIs (associated with the computer’s operating system and its various applications) certain narrative traditions have been presented in a multiple, simultaneous and overlapping way within the mise en scène as opposed to the singular and sequential manner that films have typically represented time and space by showing one shot, one spatio-temporality, within the frame at a time. The first chapter recounts the history of the screenlife film and how it has had several iterations because of what had been possible to display within GUIs at various periods between 2002 and 2018, notably the types of video calls, websites and social media. The second chapter proposes a screenlife mise en scène that divides the screen space into three levels to articulate how cinematic and narrative traditions have been transposed into Unfriended, Unfriended: Dark Web and Searching. The third chapter is a continuation of this process, but with a focus on mystery fiction techniques, clues and red herrings, present in each of these three screenlife films. The description and analysis confirms that these mystification traditions are also transposed into the GUIs in a multiple, simultaneous and overlapping way from the singular and sequential manner that they have been presented in detective novels and traditionally shot mystery genre films.

Passive Coherent Location (PCL), eller Passiv Radar som det populärt kallas, är enteknologi inom radarlära som innefattar radartyper som inte själva skickar ut elektromagnetiska vågor för att finna och undersöka ett mål. Istället använder sig dessa radartyper av befintliga signaler, såsom radio- och TV-sändningar för att detektera mål. På så vis är det betydligt svårare att upptäcka en passiv radar jämfört med en traditionell aktiv radar. SAAB utvecklar teknologi och metoder för passiva radarsystem. För att få en förståelse för ett av deras PCL-systems prestanda behöver SAAB utveckla en enkel metod för att fastställa radartäckningen. Som ett steg till detta har SAAB därför givit författaren till denna rapport i uppgift att skapa ett gränssnitt som kombinerar och jämför PCL-systemet med detektioner från en automatic dependent surveillance broadcast (ADS-B). Detektionerna från ADS-B kan då fungera som ett facit för hur väl PCLsystemet tar upp detektioner. Vilket ger gränssnittets användare en god indikationför PCL-systemets utsträckning och reliabilitet. Intervjuer hölls med anställda på SAAB som har erfarenhet av att arbeta med likvärdiga system och dess gränssnitt. Intervjuerna var semistrukturerade med frågor som syftade att utforska vilka funktioner som uppskattas och vilka svårigheter deltagarna ser i nuvarande gränssnitt. Utefter deltagarnas svar på intervjuerna byggdes en behovsanalys som tillsammans med teorier inom området låg till grund för utformningen av gränssnittsprototypen. Lösningsförslaget är en gränssnittsprotyp som visar datapunkter där detektion av mål visas från PCL-systemet och ADS-B. / Passive Coherent Location (PCL), or more popularly known as Passive Radar, is a subgenre within the field of radartechnology which includes radar types that does not transmit electromagnetic signals by themselves to find and investigate targets. Instead, they use already existing transmission, such as radio and TV broadcasts, to detect a target. Thus, it is much harder to discover a passive radar compared to a traditional active radar. SAAB is developing technologies and methods for passive radar systems. To get an understanding of the performance of one of their PCL systems, SAAB is looking for a simple method to determine the coverage of the radar. As part of this SAAB has given the author of this report the task of developing an interface which combines and compares the PCL-system with the detections of an automatic dependent surveillance broadcast (ADS-B). The detections from the ADS-B can then act as an answer key for how well the PCL-system detects targets. Thus, giving the interfaces user a good indication for the PCL-systems coverage and reliability. Interviews were conducted with SAAB employees experienced in working with similar systems and their interfaces. These interviews were semi-structured, with questions aiming to explore appreciated features and identified challenges in the current interfaces. A needs analysis was constructed based on the participants answers in the interviews, which, combined with theories within the field served as the foundation for designing the interface prototype. The proposed solution is an interface prototype, displaying data points from the PCL system and ADS-B.

The Emergency department at Södersjukhuset currently suffers from very long waiting times. This is partly due to problems within visualisation and mapping of patient data and other information that is fundamental in the handling of patients at the Emergency department. This led to a need in the creation of improvement suggestions to the visualisation of the patient flow between the Emergency department and the Gastroenterology department at Södersjukhuset. During the project, a simulated graphical user interface was created with the purpose of mimicking Södersjukhusets current patient flow. This simulated user interface would visualise the patient flow between the Emergency department and the Gastroenterology department. Additionally, a patient symptoms estimation algorithm was implemented to guess the likelihood of a patient being admitted to a department. The result shows that there are many possible improvements to Södersjukhusets current hospital information system, TakeCare, that would facilitate the care coordinators work and in turn lower the waiting times at the Emergency department. / Akutmottagningen på Södersjukhuset har i dagsläget väldigt långa väntetider. Detta beror till viss del utav problem inom visualiseringen och kartläggning av patient data och annan fundamental information för att hantera patienter på akutmottagningen. Detta ledde till att det finns ett behov att skapa förbättringsförslag på visualiseringen av patientflödet mellan akutmottagningen och gastroenterologiavdelningen på Södersjukhuset. Under projektets gång skapades ett simulerat användargränssnitt med syfte att efterlikna Södersjukhusets nuvarande patientflöde. Denna lösning visualiserar patientflödet mellan akutmottagningen och gastroenterologiavdelningen. Dessutom implementerades en enkel sorteringsalgoritm som kan bedöma sannolikheten om en patient skall bli inlagd på en avdelning. Resultatet visar att det finns flera möjliga förbättringar i Södersjukhusets nuvarande elektroniska journalsystemet, TakeCare, som skulle underlätta vårdkoordinatorernas arbete och därmed sänka väntetiderna på akutmottagningen.

Effective heat management is essential for preserving performance and dependability as electronic equipment becomes increasingly powerful and smaller. This project presents the developed system, TeRMeS, which was created to test the thermal resistance of thermal interface materials (TIMs) essential for the thermal management of electronic devices, including battery systems. This work focuses on using steady-state techniques to evaluate TIMs under various operational forces and temperatures in real-world electronic packaging conditions. A noteworthy breakthrough is the creation of a user-friendly graphical user interface (GUI), which offers sophisticated options for real-time thickness measurement and enables researchers to alter parameters and dynamically display outcomes, thereby improving the measuring process. The results of the experiment highlight the importance of TIM thickness and applied force in lowering thermal resistance and increasing thermal conductivity. These elements are necessary to prevent battery packs and electrical parts from overheating. To improve heat management strategies in high-performance computing and electronics, the study provides accurate, reliable data by focusing on steady-state measurements.

Virtual Reality is rapidly growing in popularity. This new medium offers manypossibilities for those who wish to explore what the technology provides in the 3Denvironment. However, the design principles that have been used for decades revolvearound 2D surfaces and applying them in the 3D space can cause severalincompatibility issues that diminishes the user experience.This study aimed to help highlight what aspects of virtual reality need to be improvedcompared to non-virtual reality platforms to enhance the user experience. To do this,VRChat, a virtual reality platform was chosen, which can be used by both VR, and nonVR headset users alike. By comparing these two user bases it could help highlight thepros and cons of the current system and help give guidelines on how to create futureVR platforms. During the test period, 58 people participated who did specific tasks onthe platform and filled out the quantitative data gathering survey, based on the UserExperience Questionnaire (UEQ) test.After comparing the two user bases, the result shows that there is no significantdifference between using VRChat either way allowing both user bases to enjoy theplatform equally. However, because of these results, the work failed to highlight whataspects of a VR platform need to be changed to fit the needs of VR headset users. Itimplies the need for further research and experimenting with the medium. In the future,further research, testing and experimentation are needed to improve the current designmodels and make the systems more pleasant for VR headset users.

While a lot of efforts have been on outdoor intelligent systems, internal living environment system that suits the occupancy’s behaviour has not received much attention. The intelligent living environment designed in this study has three components; the physical world (environment), the database and the decision maker. The study sought to design a model that senses ever changing home conditions such as lights, doors and windows. Other variables that were looked at include, but not limited to the number of people in the room and inside thermodynamics and human activity. Global information such as temperature, gas or electricity usage and time of the day will also be received by the system through various sensing facilities. The information will be sent to a rules engine for a decision on an appropriate action to be taken. The action may include just turning off the lights, in the case of a mild abnormality or a high alert to an emergency response unit in a most severe case. The study proposes a context aware and proactive neural networks control system to control a living environment with a main focus on the aged citizens living alone. The proposed living environment was not developed to an actual or “mock” building containing a representation of subset of sensors, actuators and controllers as used in the actual systems due to lack of funding. However, the study will report on the modelling and simulation of the home system variables based on the chosen Artificial Intelligent technique using MATLAB/SIMULINK. These results indicate a possibility of implementing the designed living environment to increase the resident’s security. / Electrical and Mining Engineering / M. Tech. (Engineering: Electrical)

A pragmatic method for selecting components and devices from a database or parameterized models is developed in this thesis. The quantitative framework presented here is sufficiently general to accommodate an entire device assembly, a component, or a sub-assembly. The details pertaining to a device or a component are classified into three sets of variables: (i) user-specifications, s (ii) device parameters, p , and (iii) device characteristics, c . Functional, practical, and performance-related attributes that a user can provide comprise user-specifications. Since, most often, a specification cannot be specified as a single number, we allow the user to enter a range with lower and upper bounds. Device parameters comprise the geometry and material properties, and device characteristics include functional requirements and performance criteria. Thus, for a device, all its functional and utility attributes are contained in the union of sets s and c , whereas the geometry and the material properties are in set p . The equations governing the physical behavior of the device are written in terms of s , p , and c . These equations may sometimes be readily available; when they are not, it may be necessary to formulate them as required. By solving the governing equations along with the inequalities that arise from the lower and upper bounds on s , we obtain feasible ranges on p and c . Then, for any pair of device characteristics, a 2D feasible map is drawn, to visually portray the consequences of user-specifications. If the feasible map is null, small, or large, it indicates that the user-specifications are infeasible, stringent, or there is much scope for design, respectively. This can be inferred even before the designs are considered. Juxtaposed on the feasible map are points or lozenges corresponding to the quantitative attributes of the entries in the database. The ones that lie inside the feasible map can be reckoned as meeting the user-specifications and thus, enabling selection. On the other hand, if there is no database or none of the devices in the database lie inside the feasible map, we can identify the feasible ranges of all the design parameters for every point inside the feasible map. This information is useful to the designer to redesign and arrive at feasible designs by using parameterized models of the device. A Graphical User Interface (GUI) is developed to facilitate the user-interaction. The utility of the selection framework is demonstrated with a variety of case-studies including miniature pumps, heat pulse-based soil-moisture sensors, springs, flywheels, compliant mechanisms, micromechanical suspensions, etc. The latter two use kineto-elastic characteristics of deformable components. The framework, when used for materials selection, can be seen as an extension of Ashby’s materials selection method. This is also illustrated with two examples.

Creating immersive experiences for virtual reality (VR) presents new design opportunities and challenges that do not appear when creating experiences on a screen. Creating prototypes and exploring concepts in VR is today limited to professionals with previous knowledge in 3D application development, and testing 3D experiences requires the usage of an Head-Mounted Display (HMD), which forces professionals to switch medium from the computer to an HMD. With new advances in this field, there have to be new solutions to these challenges. The goal of this thesis is to explore how VR technology can be utilized in the experience design process for VR. This is achieved through a literature study and conducting expert interviews, followed by a hardware evaluation of different HMDs and concept creation using rapid prototyping. From the interviews, a number of issues could be identified that correlates with the research from the literature study. Based on these findings, two phases were identified as suitable for further improvements; Concept prototyping and testing/tweaking of a created experience. Lo-fi and hi-fi prototypes of a virtual design tool were developed for HTC Vive and Google Daydream, which were selected based on the hardware evaluation. The prototypes are designed and developed, then tested using a Wizard of Oz approach. The purpose of the prototypes is to solve some of the issues when designing immersive experiences for HMDs in the suitable experience design phases that were identified by analyzing the interview results. An interactive testing suite for HTC Vive was developed for testing and evaluation of the final prototype, to verify the validity of the concept. Using Virtual Reality as a medium for designing virtual experiences is a promising way of solving current issues within this technological field that are identified in this thesis. Tools for object creation and manipulation will aid professionals when exploring new concepts as well as editing and testing existing immersive experiences. Furthermore, using a Wizard of Oz approach to test VR prototypes significantly improves the prototype quality without compromising the user experience in this medium.

Internet and websites are today one of the most important communication channels of almost all companies. They offer a simple, fast and effective way of communication, which is also available worldwide in a few seconds. With the globalization of market, more and more companies try to expand their business beyond the territory of the home state. In the current time of start-ups is the Internet also often a medium that allows formation of new spheres of business for which the website is absolutely essential channel. This type of business is internet based and has very often international ambitions from the very beginning. Given that each country (or region) can be seen as distinctive culture, it is advisable to locate websites for the needs of the foreign country. This is exactly the theme of this thesis. The concrete objective of this thesis is to offer a methodology for website localization in terms of webdesign. The basic building block is the delimitation of a multidisciplinary theoretical framework that examines the concept of culture and extensive literature review allowing current insight into the linking of website and culture, i.e. cultural website localization. Suitable method for gripping such a complex concept as a culture emerge from a theoretical framework as well. As the most appropriate method were determined Hofstedes cultural dimensions, which are then used for the analysis of cultural determination of web elements. Data collection for the purpose of analysis of web elements cultural determination is performed using a content analysis of websites from nine different countries. The results of the analysis are compared and synthesized with the findings stemming from a literature review. The final artifact of this thesis, a methodology for website localization from the perspective of web design, is based on this ground. Validation of the proposed methodology is done on the basis of assessment of the methodology for a domain of web design. This assessment is based on interviews with experts from different countries as well as presentation of concrete example of methodology use within a midsize website.
