Industrial WiFi Redundancy MethodsHenrysson, Fabian, Dizdarevic, Oliver January 2024 (has links)
This thesis explores various Wi-Fi redundancy methods to enhance network resilience in industrial settings. Maintaining uninterrupted data transmission is crucial due to the increasing reliance on wireless technologies for industrial operations. Our research investigates the performance of different redundancy strategies, including Multi-Link Operation (MLO) and Truncated Automatic Repeat Request (TARQ), through practical prototyping and testing on specific hardware configurations. We aim to assess these methods' effectiveness in mitigating packet loss and improving transmission consistency under varying attenuation. The findings are expected to provide valuable insights into the potential of existing redundancy methods to improve Wi-Fi network robustness. This thesis evaluates two main redundancy methods: MLO and TARQ. In our findings, MLO demonstrated improved packet transmission consistency at lower levels of signal attenuation compared to standard implementations. TARQ, particularly on the 2.4 GHz band, significantly reduced packet loss across a wide range of attenuation levels, thus showing its potential to enhance network reliability.

On the use of WiMAX and Wi-Fi in a VANET to provide in-vehicle connectivity and media distributionMojela, Lerotholi Solomon 12 1900 (has links)
Thesis (MScEng)--Stellenbosch University, 2011. / ENGLISH ABSTRACT: The recent emergence of ubiquitous wireless connectivity and the increasing
computational capacity of modern vehicles have triggered immense interest in the
possibilities of vehicular connectivity. A plethora of potential applications for vehicular
networks have been proposed in the areas of safety, traffic infrastructure management,
information, and entertainment. The broad range of applications requires creative utilisation
of the available wireless medium, using a combination of existing and novel wireless
technologies. In this research the evaluation of one such configuration is performed.
Dedicated short range communication for safety applications is assumed, and the use of Wi-
Fi and WiMAX for non-safety applications is evaluated. Little is known about the media
streaming performance of these wireless technologies in realistic vehicular ad-hoc network
(VANET) scenarios. Due to the extreme mobility and unpredictable environmental aspects in
a real road environment, an empirical evaluation is performed and presented. Evaluation of a
multi-vehicle to infrastructure (V2V2I) VANET, using Wi-Fi for the vehicle-to-vehicle
communication and WiMAX for the vehicle to infrastructure (V2I) communication is
experimented. It is observed that Wi-Fi is unaffected by the vehicle speed; whenever nodes
are within communication range, data gets transferred normally. A detailed characterisation
of the network architecture is presented and the results show that a multitude of applications
can be supported with this proposed network architecture. / AFRIKAANSE OPSOMMING: Die toenemende beskikbaarheid en digtheid van koordlose netwerke en die verhoogde
verwerkingsvermoëns van moderne voertuie het die afgelope paar jaar aansienlike
belangstelling gewek in die moontlikhede wat voertuig-kommunikasie bied. ʼn Magdom
moontlike toepassings is voorgestel in ʼn wye verskeidenheid van velde insluitende veiligheid,
verkeersinfrastruktuur, informasie en vermaak. Hierdie voorstelle vereis die kreatiewe
benutting van die beskikbare en nuwe koordlose tegnologieë. Hierdie tesis evalueer een
voorbeeld van so ‘n opstelling. ʼn Toegewyde kortafstand kommunikasie modus vir
veiligheidstoepassings word aangeneem, terwyl Wi-Fi en WiMAX vir ander toepassings
evalueer word. Daar is min navorsing oor die kapasiteit en seinsterkte van hierdie beskikbare
netwerke onder realistiese voertuig netwerk (VANET) scenario‘s. Weens die hoë mobiliteit
van voertuie en ook die onvoorspelbaarheid van hierdie omgewing word ʼn empiriese
evaluasie beskou as die mees gepaste metode. Die navorsing ondersoek ʼn multi-voertuig-totinfrastruktuur-
netwerk wat Wi-Fi gebruik vir voertuig-tot-voertuig (V2V) kommunikasie en
WiMAX vir voertuig-tot-infrastruktuur (V2I) kommunikasie. Die navorsing bevind dat Wi-Fi
nie beïnvloed word deur die spoed van die voertuig nie: wanneer die nodes binne die bereik is
van die netwerk word data normaal oorgedra. ‗n Gedetailleerde karakterisering van dié
netwerk word gedoen en die resultate dui aan dat ‗n groot hoeveelheid toepassings
ondersteun kan word deur dié opstelling.

Lo-Fi aesthetics in popular music discourseHarper, A. C. January 2014 (has links)
During the late twentieth and early twenty-first centuries, 'lo-fi,' a term suggesting poor sound quality, the opposite of 'hi-fi,' became a characteristic perceived in certain popular-music recordings and eventually emerged as a category within independent or 'indie' popular music. It is typically taken to express the technical and technological deficiencies associated with amateur or 'DIY' musical production, namely at home using cheap recording equipment. However, this thesis rejects the assumption that lo-fi equates to a mode of production and charts it as a construction and a certain aesthetics within popular music discourse, defined as 'a positive appreciation of what are perceived and/or considered normatively interpreted as imperfections in a recording.' I chart the development and manifestation of lo-fi aesthetics, and the ways it focuses on various 'lo-fi effects' such as noise, distortion ('phonographic imperfections') and performance imperfections, in several decades of newspapers, magazines and websites covering popular music in the English-speaking world. I argue that lo-fi aesthetics is not merely the unmediated, realist authenticity that it is often claimed to be, but one that is also fascinated with the distance from perceived commercial norms of technique and technology (or 'technocracy') that lo-fi effects signify. Lo-fi aesthetics derives from aesthetics of primitivism and realism that extend back long before phonographic imperfections were positively received. I also differentiate between lo-fi aesthetics and aesthetics of noise music, distortion in rock, glitch, punk and cassette culture. An appreciation for recording imperfections and the development of 'lo-fi' as a construction and a category is charted since the 1950s and particularly in the 1980s, 1990s and in the twenty-first century, taking in the reception of artists such as the Velvet Underground, Bob Dylan, Hasil Adkins, the Shaggs, Jandek, Daniel Johnston, Beat Happening, Pavement, Sebadoh, Guided By Voices, Beck, Will Oldham, Ariel Pink and Willis Earl Beal.

The Smart Home From a Security PerspectiveChristensson, Daniel, Eriksson, Emelie January 2019 (has links)
Based on the fact that many electronic devices are digitalized in our world in order to facilitate our lives, there is a large potential for development in the home. Smart Home solutions are giving us the opportunity to control and manage for example alarms, electricity and surveillance but the technology's rapid improvement paves the way for issues related to security. The objectives for this work will bring up common communication technologies, security and vulnerabilities in the context of a Smart Home and what could be done for future work. In order to investigate the objectives, a literature study has been conducted together with an experiment. The experiment result exploits a weakness in a common Smart Home technology used in the network enable devices in the form of threats and vulnerabilities. In order to mitigate and minimize threats and vulnerabilities one conclusion is that a security policy could be produced. This security policy should provide the user with good practice of how to manage security in order to mitigate vulnerabilities and threats within the Smart Home.

Estimativa da ocupação utilizando sensoriamento wi-fi de telefones móveis: uma aplicação no transporte público urbano de passageiros por ônibus. / Estimating the occupancy using Wi-Fi sensing of mobile phones: an application of the urban public transportation by bus.Nunes, Edson Hilios Marques 25 March 2019 (has links)
A lotação do veículo é um dos fatores determinantes para a qualidade do transporte público (TP), pois, além do conforto do passageiro, afeta também a confiabilidade da linha, alterando a velocidade média do veículo. Entretanto, na cidade de São Paulo, Brasil, uma das maiores operações de ônibus do mundo, é difícil se encontrar implantado algum equipamento de contagem automática de passageiros (APC), provavelmente devido aos custos das tecnologias atuais. Esta pesquisa apresenta os resultados de um método de APC utilizando o sensoriamento por Wi-Fi de telefones móveis dos passageiros embarcados num veículo do TP por ônibus. Para este fim, um protótipo de baixo custo foi desenvolvido e instalado na linha 6500-10 entre o Terminal Santo Amaro e o Terminal Bandeira, durante 7 dias da semana em horários de pico e entre pico. Os dados coletados foram analisados através de ferramentas estatísticas e métodos de análise geográficas. Durante o experimento observou-se que o APC foi capaz de detectar a mudança da ocupação do veículo em 85% dos casos, com uma confiança de até 20% e um erro de até 22 passageiros por medida. Através de dados de posição geográfica foi possível gerar matrizes de carregamento, que permitem inferir a origem e o destino dos passageiros em cada viagem, assim como - para todo o período do experimento - indicar os trechos com maior lotação. Por outro lado, o método não apresentou bons resultados saindo dos terminais e quando a ocupação mudou repentinamente, requerendo estudos posteriores para refinar o algoritmo apresentado. Da mesma maneira, ainda não há como generalizar o método para toda operação, pois, o espaço amostral estudado foi pequeno, deixando como sugestão para pesquisas futuras o aprimoramento deste sistema. / The crowdedness of a vehicle is one of the main quality factor of the public transportation (TP) quality, since, besides the comfort, also affect the reliability of the line, changing its average speed. However, the city of São Paulo, Brazil, one of the biggest bus operations of the world, it is difficult to find any automatic passenger counter (APC) equipment deployed, probably due the costs of current technologies. This research shows the results of an APC technology by the sensing of the Wi-Fi signal of smartphones that are boarded in a vehicle on TP by bus. Therefore, a prototype was developed and deployed on the line 6500-10 between the Terminal Santo Amaro and the Terminal Bandeira, during 7 working days of the week on peak and off-peak hours. was analyzed with statistical and geographical tools. During the experiment, it was observed that the Wi-Fi APC was capable of estimate the occupancy of the vehicle 85% of the cases, with a significance level up to 20% and an error up to 22 passengers per estimation. Through the geographical analysis it was generated load matrices, that allow to infer the origin and destination of the passenger in each trip, indicating the sections along the route where were more boarding and alighting. On the other hand, the method did not perform well when coming out of the final stops and when the crowdedness changed suddenly, requiring further analysis to understand how to deal better under these circumstances. Likewise, due to the limited sample utilized in this research, we cannot generalize the results presented, pressing the need for new researches on different operation scenarios.

Síla fikce: zpracování enviromentální tematiky v americké kinematografii / The Power of Fiction: enviromental issues in American cinemaHolá, Kateřina January 2019 (has links)
This master thesis deals with one of the current trends in cinema - the so-called climate change film. Film as a popular medium is able to influence public debate and this paper's main objective is to explain how environmental issues can be portrayed in film and how such films shape the climate change debate. In the first, theoretical part of this thesis, the aim is to briefly introduce the history and context of climate change debate from the 1970s to the present day based on sources primarily from interdisciplinary cultural and environmental studies. It also explains how environmental problems started to arise in different art spheres, above all in American cinema from 1995 to the present. The second part analyzes four American feature films of different genres: The Day After Tomorrow (2004) directed by Roland Emmerich's, The Road (2009) directed by John Hillcoat, Before the Flood (2016) directed by Fisher Stevens and Darren Aronofsky's mother! (2017). The final chapter summarizes the findings, explains the currently prevalent apocalyptic narrative and discusses why such approach is not effective and how filmmakers need to transform climate change stories into positive narratives that inspire change and hope.
