Our study investigates when people quit playing unaltered Valheim (2021) and what the inciting factors were among those frustrations. Research into occurrences of frustration helped us gain a better understanding of how players' expectations come into play as well as how players allocate their resources when it comes to video games. This understanding allows game developers to mitigate frustration in open-world survival games. The study was conducted by interviewing participants who had played the game for more than 25 hours and had quit playing unaltered Valheim (2021). The participants were obtained from a survey used to screen potential candidates for the interviews. We approach this study through the lens of Conservation of Resource theory and Need Frustration. We observed that participants' prior experience in games played a significant role, apart from the gameplay itself, in deciding whether the game they played was worth the resources they chose to invest. Ultimately, the participants felt that the game was being unfair towards them and to continue playing the unaltered game would be a waste of resources.

Denna studie syftar till att undersöka hur ungdomars psykiska hälsa kan påverkas av fysisk interaktion på fysiska samlingsplatser samt deras motiv för att intressera sig för meningsfyllda fysiska samlingsplatser. Undersökningen genomfördes genom en kvalitativ ansats i formen av en litteraturstudie. Resultatet visar indikationer på att fysisk interaktion kan vara positivt för ungdomars psykiska hälsa. Meningsfulla fysiska samlingsplatser kan vara platser för fysisk interaktion och därigenom är platser där ungdomars psykiska hälsa kan påverkas. Resultaten visar också indikationer för ett samband mellan användningen av sociala medier via vistelsen på digitala samlingsplatser och symtom på psykisk ohälsa. Ungdomar uppger att de helst vill spendera sin fritid på aktiviteter som de tycker är roliga och intresserar dem. I analysen framkommer det att många av de ungdomar som rapporterade en bättre psykisk hälsa hade en högre benägenhet att delta i gemenskapsbundna fritidsaktiviteter. Detta fenomen förklaras med hjälp av känslan av meningsfullhet och deras förmåga av hanterbarhet enligt KASAM-teorin. Det diskuteras sedan behovet av struktur och hur saknaden av struktur verkar påverka ungdomarnas förmåga att lära sig ett prosocialt beteende, samt möjligheterna att delta i strukturerade fritidsaktiviteter. Slutsatserna är att det behövs ytterligare forskning på området men att det verkar finnas tendenser som pekar på att fysisk social interaktion medför en bättre psykisk hälsa än digital social interaktion.

This thesis presents a new design process in which design specifications and task distribution are determined from a parallel multi user prospective. Using this method, projects are more easily decomposed into tasks that can be performed concurrently, thus decreasing the design time. Also, a framework is provided to determine the correct distribution of available talent and stakeholders that can be utilized on a given project. The research suggests that by involving the necessary stakeholders in a multi user setting, changes can be made quickly and without additional approval wait time. By including individuals from the various areas of required talent, persons of expertise will be able to work together in a mode of shared design rather than an iterative design process. Decreasing iterations as well as reducing wait time for approval will reduce the overall design time significantly. This method has been tested and validated utilizing controlled tests simulating real life situations of much larger scale. The validation results show that the new method does in fact improve design time and overall achievement of initial design goals

One of the major themes in the Book of Mormon is the promises of the Lord to the house of Israel. Even before Lehi and his family left the promised land, Lehi and Nephi prophesied of the future scattering and gathering of Israel. After the family of Lehi arrived on the Americas, prophets continued to teach about God’s covenants with Israel. The destiny of the house of Israel was a major theme in the books of 1 and 2 Nephi, and also at the end of the Book of Mormon in the teachings of Jesus Christ, Mormon, and Moroni.In Lehi’s prophecy about the house of Israel in 1 Nephi 10, he prophesied that the future remnants of the house of Israel would be scattered and then defined how they would be gathered together again. They would do so by coming to the knowledge of their Lord and Redeemer (see 1 Nephi 10:14, emphasis added). When teaching about the house of Israel, many prophets taught similar principles as Lehi. Additionally, many prophets—including Nephi, Jacob, Alma, Samuel, Jesus Christ, Mormon, and Moroni—alluded to Lehi’s same phrase when they taught about the house of Israel during their own ministries. In the various sermons about the covenants of God with the house of Israel, several prophecies and principles were repeated. All of the major writers on the plates knew that the remnant of Israel would be scattered. They also taught that in the latter days, the gospel would go forth first to the Gentiles, who would in turn gather the scattered remnants of Israel. The instrument and tool by which they would be gathered would be the writings of the Nephite prophets – the Book of Mormon. Most important, the Gentiles and house of Israel would be gathered by coming to the knowledge of Jesus Christ as their Redeemer. The Book of Mormon prophets understood these teachings and engraved them on the plates to come forth to the world in the latter days. This thesis surveys the teachings of the prophets in the Book of Mormon about the gathering of the house of Israel. It also discusses the allusions and references to Lehi’s prophecy about how the Gentiles and house of Israel will be gathered – by coming to the knowledge of Jesus Christ, their Lord and their Redeemer.

Wireless sensor networks (WSNs) typically consist of a significant number of inexpensive sensor nodes, each of which is powered by a battery or another finite energy source that is difficult to replace because of the environment they are in or the cost of doing so. The applications of WSNs include military surveillance, disaster management, target tracking and monitoring environmental conditions. In order to increase the lifespan of WSNs, energy-efficient sensing and communication approaches for sensor nodes are essential. Recently, there has been an increase in interest in using unmanned aerial vehicles (UAVs) as portable data collectors for ground sensor nodes in WSN. Several approaches to solving effective communication between sensor nodes and the fusion center have been investigated in this thesis. Because processing, sensing range, transmission bandwidth, and energy consumption are always limited, it is beneficial not to use all the information provided at each sensor node in order to prolong its life span and reduce communication costs. In order to address this problem, first, efficient measurement quantization techniques are proposed using a single fusion center and multiple sensors. The dynamic bit distribution is done among all the sensors and within the measurement elements. The problem is then expanded to include multiple fusion centers, and a novel algorithm is proposed to associate sensors to fusion centers. The bandwidth distribution for targets which are being monitored by several sensors is addressed. Additionally, how to use the situation in which the sensors are in the coverage radius of multiple fusion centers in order to share the targets between them is discussed. Finally, performance bounded data collection algorithms are proposed where the necessary accuracy for each target is specified. In order to determine the minimum number of data collectors needed and their initial placement, an algorithm is proposed. When there are fewer fixed data collectors than there are regions to collect the data from, a coverage path planning method is developed. Since the optimal solution requires an enormous computational requirement and not realistic for real-time online implementation, approximate algorithms are proposed for multi-objective integer optimization problems. In order to assess each suggested algorithm's effectiveness, many simulated scenarios are used together with baselines and simple existing methods. / Thesis / Doctor of Philosophy (PhD)

Denna rapport avser att undersöka för- och nackdelar med att utveckla ett för ändamålet specialanpassat system eller utnyttja de standardsystem, som i det aktuella fallet tryckerikoncernen JMS redan äger och använder. Genom en mer noggrann definiering av ickefunktionella krav på bland annat användbarhet har en specialanpassad prototyp framställts. I projektet användes metoder för kravinsamling som ledde till en kravspecifikation och i sin tur slutade med en färdig prototyp. Prototypen jämfördes med två standardsystem genom användartester och intervjuer. Prototypen visade sig leva upp till de krav som upptäcktes. Majoriteten av testpersonerna föredrog ett enklare avskalat system, vilket prototypen upplevdes som, före system med mycket information och funktioner. Med tanke på kostnaden rekommenderas dock JMS att försöka strukturera upp ett av de i företaget befintliga systemen och använda detta istället för att utveckla och implementera ytterligare ett nytt system i företaget. / This report intends to explore the pros and cons of developing a customized system or use the standard system, which in this case printing JMS Group already owns and uses. With a more accurate definition of non-functional requirements such as usability, has a custom-made prototype been built. The project used methods of requirements gathering that led to a specification and ended with a finished prototype. The prototype was compared with two standard systems through user testing and interviews. The prototype proved to live up to the requirements discovered. The majority of test subjects preferred a simpler clean system, which the prototype was, to systems with a lot of information and functions. Given the cost JMS was recommended to structure one of the systems that they already owns and uses instead of developing and implementing a new system further in the company.
