Idag tillämpar nästan alla verksamheter någon form av affärssystem och har kommit att bli ett betydande system för verksamheter. Under de senaste åren har även molnbaserade affärssystem vuxit fram vilket möjliggör verksamheter att använda hela eller delar av sitt affärssystem över internet istället för att behöva sköta all hantering av det fysiska lokalt. Det molnbaserade affärssystemet kan leda till flera fördelar för verksamheter då det kan öka flexibiliteten, skalbarheten och minska kostnader. Det blir bara fler verksamheter som väljer att gå över till det molnbaserade dock finns det vissa som arbetar kvar med det traditionella. Med utgångspunkt från detta är syftet med denna studie att se vilka aspekter det är som påverkar valet att gå från det traditionella affärssystemet till ett molnbaserat. För studien har tidigare litteratur studerats och intervjuer har genomförts för insamling av empiri. Tidigare forskning ligger till grund för det teoretiska ramverk som ligger till grund för de intervjufrågor som tagits fram. Det har intervjuats tre olika respondenter där alla har god förståelse kring ämnet och antingen arbetar i ett affärssystem eller arbetar som leverantör av dem. Det har främst ställts frågor kring de fem olika aspekter som vi anser varit betydelsefulla i denna studie. Men även frågor kring fördelar och nackdelar av de olika affärssystemen. Detta har krävts för att vi författare ska få en så god förståelse kring ämnet som möjligt. Utifrån det insamlade teoretiska material och empiri utfördes en analys där den tidigare litteraturen framfördes mot den insamlade empirin för att kunna få fram en helhetsbild över hur verksamheten förhåller sig kring ämnet och vilka aspekter det ser är betydande vid valet av affärssystem. Avslutningvis leder detta fram till en slutsats som presenteras med de allra mest väsentliga aspekter som har kommit fram i studien.

Implementering av affärssystem inom verksamheter kan ge många fördelar, exempelvis effektivisering och automatisering. Hur systemet levereras till kunden kan påverka förtroendet hos kunden. Förtroendet är viktigt för att bibehålla en god relation mellan kund och leverantör och för att kunden inte ska känna osäkerhet kring att implementera affärssystem. Affärssystem kan implementeras lokalt hos kunden On-Premise eller i molnet  vilket tillhandahålls hos leverantören i form av Software as a Service (SaaS). Syftet för studien var att undersöka skillnader i kunders förtroende till On-Premise och SaaS-system och kartlägga faktorer vilket kan påverka förtroendet som testades med en modell för att mäta förtroende skapad av McKnight (2009). Utifrån modellen samt tidigare forskning inom området formulerades åtta hypoteser. Hypoteserna testades med hjälp av svar från en enkät som skickades ut till kunder av On-Premise och SaaS-system. Totalt blev det 72 svar som analyserades med hjälp av ett ANOVA test vilket slutligen bekräftade fyra av åtta hypoteser. Resultatet indikerade att det inte föreligger någon signifikant skillnad mellan de två urvalsgrupperna. Resultatet tyder på ett ökat förtroende för SaaS vilket tidigare inte innehaft ett lika högt förtroende, dessutom visar det på att digitaliseringen rör sig framåt med ett ökat förtroende för molntjänster trots de risker som tillkommer. Studiens resultat har potentiell relevans för leverantörer av både On-Premise- och SaaS-system genom att öka förståelsen för kundernas förtroende. Slutligen kan leverantörer anpassa system efter kundernas behov, förbättra säkerhet och kvalitet samt främja en gynnsam och långsiktig relation mellan leverantör och kund. / Implementation of business systems within organizations can provide many advantages, such as efficiency and automation. How the system is delivered to the customer can impact the trust of the customer. Trust is crucial for maintaining a good relationship between the customer and the supplier and for preventing the customer from feeling uncertainty about implementing business systems. Business systems can be implemented locally at the customer's site On-Premise or in the cloud, provided by the supplier in the form of Software as a Service (SaaS). The purpose of the study was to examine differences in customer trust in On-Premise and SaaS systems and to identify factors that may affect trust, tested with a model to measure trust created by McKnight (2009). Based on the model and previous research in the field, eight hypotheses were formulated. The hypotheses were tested using responses from a survey sent to customers of On-Premise and SaaS systems. In total, there were 72 responses that were analyzed using an ANOVA test, which ultimately confirmed four out of eight hypotheses. The results indicated that there is no significant difference between the two sample groups. The results suggest an increased trust in SaaS, which previously did not have as high trust. Additionally, it shows that digitization is progressing with increased trust in cloud services despite the associated risks. The study's results have potential relevance for providers of both On-Premise and SaaS systems by increasing understanding of customer trust. Ultimately, providers can tailor systems to customer needs, improve security and quality, and promote a favorable and long-term relationship between supplier and customer.

No / The development of the IEEE 802.22 standard is aimed at providing broadband access in rural areas by effectively utilizing the unused TV band, provided no harmful interference is caused to the incumbent operation. The motivation behind TV band selection is of having lower frequencies compared to other licensed bands, which, therefore, results in lower propagation path loss. Due to this quality, the spectral power density of the radio signal reduces slowly, which results in a high coverage area. Further, it has been observed that many TV channels largely remain unoccupied, as most households and businesses rely on cable and satellite TV services. This is the first international standard for a wireless regional area network (WRAN) based on cognitive radio technologies. This standard provides both PHY and MAC layer functionalities in an infrastructure based network for communication between customer premise equipments (CPEs) through a base station (BS). The Spectrum Manager is the central part of the BS, which plays a significant role in maintaining spectrum availability information, channel selection, channel management, scheduling quiet periods for spectrum sensing, accessing to the database and implementing IEEE 802.22 policies. A WRAN can particularly accommodate up to 512 CPEs in a cell. Contention may occur during initial ranging, periodic ranging, bandwidth request and urgent coexistence situation notification. The medium access control (MAC) incorporates several schemes to control contention between CPEs within a cell and overlapping cells sharing the same channel. A CPE has to make decision to resolve collisions in the upstream direction. In the case of initial ranging and periodic ranging, code division multiple access (CDMA) is employed to resolve collisions. For bandwidth and UCS notification, either a CDMA or exponential time backoff approach can be applied for collision resolution. This paper presents the analytical framework to evaluate the number of active CPEs in a cognitive radio network, It is important to note that when the arrival rate becomes equal to the service rate, the active CPEs curve attains a constant value. Further, the active CPEs length is highly dependent on service rate. The different special cases have been addressed and the effectiveness of the proposed framework has been validated through various evaluation results.

The development of the IEEE 802.22 standard is aimed at providing broadband access in rural areas by effectively utilizing the unused TV band, provided no harmful interference is caused to the incumbent operation. This thesis presents the analytical framework to evaluate the number of active customer premise equipments (CPEs) in a wireless regional area network. Initial ranging is the primary process in IEEE 802.22 networks for CPEs to access the network and establish their connections with the base station (BS). A comprehensive analysis of initial ranging mechanism is provided in this work and initial ranging request success probability is derived based on the number of contended CPEs and the initial contention window size. Further, the average ranging success delay is derived for the maximum backoff stages. The collision probability is highly dependent on the size of the initial contention window and the number of contended CPEs. To keep it at a specific level, it is necessary for the BS to schedule the required size of the initial contention window to facilitate the maximum number of CPEs to establish their connections with reasonable delay. Therefore, the optimized initial window size is proposed that meets the collision probability constraint for a particular number of contended CPEs. An analytical model is also developed to estimate the ranging request collision probability depending upon the size of initial contention window and the number of contended CPEs. Moreover, this approximation provides the threshold size for contention window to start the initial ranging process in the IEEE 802.22 network.

A tese parte da análise jurídica do concurso das sociedades cooperativas para abordar as disciplinas concursais de insolvência civil, recuperação de empresas e falência, bem como as normas de liquidação aplicáveis às cooperativas no direito brasileiro e comparado. O direito concursal hodierno dispõe de mecanismos recuperativos em caso de crise financeira, e liquidatórios, com normas que primam pela eficiência dos institutos do direito concursal e pela continuação da atividade produtiva, com o fim de beneficiar o credor, devedor e a coletividade. Tende-se a adotar o princípio de unidade legal, de sistema e de disciplina, com pressuposto subjetivo unificado, abrangendo todos os devedores, inclusive as sociedades cooperativas, que quando organizadas como empresas são empresárias de economia social, com natureza jurídica e estrutura que beneficiam a coletividade. O Brasil não adota o princípio da unidade, nem reconhece as sociedades cooperativas como empresas, com a exclusão das cooperativas da lei de recuperação e falências, o que fere as orientações internacionais de incentivo e de tratamento não discriminatório às sociedades cooperativas e surge como mais um obstáculo ao seu desenvolvimento no Brasil. Este estudo teórico-descritivo subdivide-se em três capítulos: o primeiro aborda a doutrina e a normativa do direito concursal com enfoque na sociedade cooperativa, analisando a evolução do direito concursal, os pressupostos subjetivos e os institutos do direito concursal brasileiro, inclusive os aplicáveis às sociedades cooperativas; o segundo aprofunda o estudo da sociedade cooperativa como empresa de economia social para demonstrar a sua realidade econômica empresarial e as suas características estruturais, além de as orientações internacionais sobre a promoção da cooperativa; e o terceiro avalia a adequação do direito concursal das cooperativas no Brasil e formula proposições sobre a matéria. A relação teoria e prática tem como base as decisões judiciais existentes sobre a matéria. / The thesis begins with the legal analysis of the bankruptcy of cooperative societies to address the legal types of bankruptcy non-commercial entities insolvency system (insolvência civil), companies recovery system and bankruptcy and the liquidation rules applicable to cooperatives under Brazilian law and comparative law. The bankruptcy law nowadays has recovery mechanisms in cases of financial crisis and liquidation. It presents rules that aim at efficiency and at the continuity of the production, in order to benefit creditors, debtors and the community. There is a tendency to adopt the legal unit principle, the system principle and the discipline principle, with a unified subjective premise that covers all debtors, including cooperative societies. When organized as companies, these societies are social economy entrepreneurs, whose juridical nature and structure benefit the community. Brazil does not adopt the legal unit principle and does not recognize cooperative societies as companies, with the exception of the cooperatives covered by the recovery and bankruptcy law. This fact constitutes a disagreement in relation to international orientations of promotion and non-discriminatory treatment to cooperative societies and arises as an obstacle to the development of these societies in the country. The theoretical-descriptive study is divided into three chapters: the first one presents the doctrine and the rules related to bankruptcy law focusing the aspects of cooperative societies and analyzing the evolution, the subjective premises and the institutes of bankruptcy law, including those applicable to cooperative societies; the second chapter analyses the cooperative society as a social economy company and demonstrates its entrepreneurs economic reality, its structural characteristics and adds international orientations on the promotion of cooperatives; the third chapter evaluates the appropriateness of bankruptcy law related to cooperatives in Brazil and formulates propositions on the issue. The relation between theory and practice is demonstrated with judicial decisions on the matter.

Background Using Microsoft Platforms as a base for creating a software solution with a web front-end, the motives and research behind the technology was explored. This study identified functionalities that are split across existing media-related applications where neither has all to develop and evaluate a novel solution with useful features for sorting and indexing media. Aim Produce a solution for the development of an application with available technology, provide research and motives for chosen implementation strategies, and an evaluation of the solution. Method Design and creation was used as a strategy for the purpose of developing and evaluating a software solution. A literature review was used as data collection method, serving as motive and research behind the development of a software solution. An evaluation on accessibility, functionality and performance was chosen to estimate the worth of the proposed solution, and to be compared with Kodi and Squeezebox. Results The proposed solution suffered in performance and accessibility. In terms of functionality, it has the edge by being cloud-hosted,having offline support and supporting multiple media types. Kodi excelled in supporting more media types and formats, with an accessibility score close to Zavorite. Squeezebox excelled in performance. Both Squeezebox and Kodi has the edge in being able to playback media, a feature Zavorite does not offer. Conclusions Zavorite is a prototype evaluated alongside product-ready applications. The areas where Zavorite is lacking compared to Kodi or Squeezebox, such as performance is made up for due to being a PWA. For accessibility, the evaluation showed what should be improved for subsequent prototypes. For functionality, despite the prototype only showcasing two media types, there is the possibility of adding more with an additional row in a database table. Zavorite can be considered a combination of Kodi and Squeezebox, with user experience improvements as a PWA, limited to sorting and indexing media.
