Researchers in software engineering proposed design method for distributed applications to construct a set of communicating system components from a global behavior. The joint behaviors of these components must precisely satisfy the specified global behavior. The next concern is to transform the constructed models of these components into executable business processes by ensuring the exchange of asynchronous messages among the generated business processes. The introduction of Service-Oriented Architecture (SOA) has helped to achieve this goal. SOA provides high flexibility in composing loosely-integrated services that can be used among business domains to carry out business transactions; this composition is known as service orchestration. Moreover, SOA supports Model Driven Architecture (MDA) such that services modeled as UML Activity Diagrams (AD) can be transformed into a set of Business Execution Language (BPEL) processes. Many researchers discussed the transformation of UML AD and the Business Process Modeling Notation (BPMN) into BPEL. However, they did not discuss the practical limitations that some of these transformations impose. This thesis addresses the imitations of the transformation from UML AD to BPEL processes using the IBM Rational Software Architect (RSA). We showed here that the tool is unable to create the correct BPEL artifacts from UML AD components in certain cases, for instance when the behavior includes the alternative for receiving single or concurrent messages, a weak loop, or certain choice activities. Furthermore, we provided novel solutions to the transformations in these cases in order to facilitate the transformation from UML AD to BPEL.

The Utah State University Aerolab developed and tested a set of tools for rapid prediction of the loudness of a sonic boom generated by supersonic transport aircraft. This work supported a larger effort led by Texas A&M to investigate the use of adaptive aerostructures in lowering sonic boom loudness at off design conditions. Successful completion of this effort will improve the feasibility of supersonic commercial transport over land. Funding was provided by a NASA University Leadership Initiative grant to several universities, including Utah State University, as well as industry partners to complete this work over a five year period. The work presented in this thesis was done over the first year of the grant. The Aerolab team was specifically tasked with developing a set of tools for rapidly predicting the sonic boom loudness of supersonic aircraft. Specifically, this work included an assessment of the existing analysis tools available followed by the planning, development, and testing of a framework of tools for performing the needed calculations. Results of the framework were compared against high fidelity solutions available from the 2017 AIAA Sonic Boom Prediction Workshop. These comparisons revealed that panel methods perform well for simple geometries. However, localized errors appear when modeling more complex geometries that reduce the accuracy of the predicted sonic boom loudness. It was found that these localized errors were a consequence of the inherent assumptions built into panel methods. Consequently, in future work, it may be necessary to develop techniques for combining the results of panel methods with higher fidelity methods or to revisit the panel method formulation.

Piste maps have been used as navigational aids by winter sports enthusiasts for decades. These maps are often hand drawn and are designed to be visually pleasing while still providing an overview of the terrain of a ski resort. As smartphones have become the go-to tool when satisfying our daily navigational needs, the expectations of a digital map have changed. One of these expectations is being able to position yourself and others on the map. With the existing GPS functionality of smartphones, there is a great potential for bringing classical piste maps into the digital age. This project proposes a solution which can position a user given their geographical position on a piste map. The solution includes a process for identifying anchor points which tie geographical coordinates to piste map coordinates, a suitable method of triangulating these points, combined with an algorithm that finds the most suitable triangle to use for finding the transformation parameters, and finally an affine transformation that yields the corresponding piste map coordinates for a given geographical position. The solution also proposes a method to find the smallest but sufficient set size of anchor points for a resort to create a useful and cost efficient model of transformation. The thesis work also presents possible implementations of the positioning algorithm, such as creating a smooth transition between a piste map view and a satellite map view in an Android device. This includes automatic panning and rotation of the satellite map in response to the centering of the piste map on the device screen. Geo-enabling piste maps enables many more interesting applications, such as recording and displaying skiing statistics, providing suggestions of new unexplored areas, keeping track of family or friends, selective location sharing, location-tagged weather and disaster information, and in the wake of the COVID-19 pandemic, providing a user- friendly interface for displaying localized congestion levels. / Skidåkare och andra vintersportsentusiaster har använt pistkartor som standarden för navigering i skidorter i flera decennier. Dessa kartor är ofta handritade av en konstnär, och är designade för att vara visuellt tilltalande samtidigt som de förser användaren med en abstraherad översikt av skidanläggningen. När mobiltelefonen tog över våra dagliga navigeringsbehov har också förväntningarna av en digital karta förändrats. En av dessa förväntningar är att kunna positionera sig själv och andra på kartan. Med hjälp av den nuvarande GPS teknologin som finns tillgänglig i mobiltelefoner finns ett stort potential för att vidareutveckling och digitalisering av den klassiska pistkartan. Detta projekt beskriver en digital lösning som kan positionera en användare givet deras geografiska koordinater på en pistkarta. Lösningen består av en process för att identifiera ankarpunkter som binder samman geografiska koordinater och pistkarte-koordinater, samt en metod för att triangulera dessa punkter. Detta är kombinerat med en algoritm som hittar den mest passande triangeln vars transformationsmatris kan användas för att transformera de givna geografiska koordinaterna till pistkarte-koordinater. Lösningen föreslår också en metod för att hitta det minsta tillräckliga antalet ankarpunkter som krävs för att skapa en användbar och kostnadseffektiv transformationsmodell. Examensarbetet föreslår också möjliga implementationer av positioneringslösningen, som att skapa en sammanhängande transition mellan pistkarta och satellit-vy i en Android app. Detta innefattar automatiska förflyttningar och rotationer av satellit-kartan beroende på hur pistkartan är positionerad i relation till skärmens centrum. Positioneringsalgoritmen möjliggör flera andra intressanta tillämpningar, som att visualisera inspelade åk-statistik, ge förslag på tidigare outforskade backar och skidområden, visa upp var vänner och familj befinner sig, selektiv platsdelning, platsrelaterad väder- och snödata, samt förutsättningar för att skapa en användarvänlig visualisering av områdesspecifika trängselnivåer.

The purpose of this thesis is to develop web-based modules for enhancing instruction of the geometry sections of the Virginia Standards of Learning in the seventh and eighth grades. While all of Virginia's seventh and eighth grade Standards of Learning strands are certainly worthy of these types of modules, geometry appeals to me most because of the vast amount of web-based resources that will be valuable when organized into modules. It is my hope that teachers of these grades will find this useful in their instruction of geometry.

Ensuring the long-term survival and competitiveness of the company is of paramount importance. As a company, adapting to Industry 4.0 (4IR) brings many new opportunities through new technologies that are developing exponentially. In logistics, companies will be able to achieve shorter lead times, fewer errors and greater flexibility. This study is about how retail operations create a successful implementation of automated warehousing to adapt to survive the era of Industry 4.0. The research question is: - How do retail operations implement automated warehouses within the Industry 4.0 framework? The collection of empirical data was done through 11 interviews with respondents from Swedish retail companies that are in the implementation process, or have completed the implementation of an automated warehouse. The respondents have a position in the company that includes knowledge about the implementation of the automated warehouse. Results show four important themes: Identification, Realization, Adaptation &amp; Valuation to create a successful implementation where companies manage to adapt to 4IR. The study shows that it is not enough for companies to follow a process description. It turned out to be more complicated than that as it requires a mental adaptation in the company itself over a long period of time and that this is really permeated in the culture and in the employees. This study has both theoretical and practical contributions. The main contribution to theory realized in this thesis is that companies that want to succeed in implementing 4IR even before the actual practical process begins need to adapt the whole company, including the visions, ways of thinking, culture, etc. to make the actual transition towards 4IR as easy as possible. From a practical point of view, this study contributes both from a societal, consumer and business perspective. / <p>Grade: A</p>
