This dissertation is the first ever which provides an annotated translation and analysis of the Gaṇitatilaka by Śrīpati and its Sanskrit commentary by the Jaina monk Siṃhatilakasūri (14th century CE). The Gaṇitatilaka is a Sanskrit mathematical text written by Śrīpati, an astronomer-mathematician who hailed from 11th century CE Maharashtra. It has come down to us together with Siṃhatilakasūri’s commentary in a uniquely extant yet incomplete manuscript. The only edition available of both Sanskrit texts is by Kāpadīā (1937). Siṃhatilakasūri’s commentary upon the Gaṇitatilaka GT is a precious source of information on medieval mathematical practices. To my knowledge, this is, in fact, the first Sanskrit commentary on mathematics –whose author is known– that has survived to the present day and the first written by a Jaina that has come down to us. This work has never before been studied or translated into English. It is my intention to show that the literary practices adopted by Siṃhatilakasūri, in expounding step-by-step Śrīpati’s work, enrich the commentary in such a way that it consequently becomes “his own mathematical text.” Together with the English translation of both the root-text by Śrīpati and the commentary by Siṃhatilakasūri, I present the reconstruction of all the mathematical procedures explained by the commentator so as to understand the way medieval Indian mathematics was carried out. I also investigate Siṃhatilakasūri’s interpretative arguments and the interaction between numbers and textual norms which characterises his work. The present research aims to: i) edit the Sanskrit edition by Kāpadīā ii) revise the English translation of Śrīpati’s text by Sinha (1982) iii) provide the first annotated English translation of selected passages from the commentary by Siṃhatilakasūri iv) highlight the contribution to our understanding of the history of Indian mathematics brought by this commentary and v) investigate Siṃhatilakasūri’s literary style.

Manual de aproximação é um embate que se quer fluido entre a pesquisa acadêmica e o caos da criação entre as Artes Visuais e a Dança. Tenta degustar sem enlatar, para mostrar aqui um resultado parcial de uma pesquisa que começou bem antes do mestrado e possivelmente não se encerrará com ele. São descritas experiências significativas em relação a três trabalhos realizados no início da pesquisa: Pele na água, Relógio Pélvico e Borboleta Pélvica. Pele na água mostra um processo de trabalho relacional que está entre a performance e a gravura. Relógio Pélvico e Borboleta Pélvica partem de um lugar da anatomia e desenvolvem-se através de encontros com pessoas interessadas no saber do movimento e da criação somáticoperformativa. Em meio às relações vividas nesses processos, elaborou-se um sentimentoideia chamado Sim-eu, que trata da potência criativa entre pessoas que apostam na integração de si com o outro. / Manual de aproximação is a clash that is intended fluid between academic research and the chaos of creation between the Visual Arts and Dance. It tries to taste withoutcanning in order to show here a partialresult of a research that started well beforethe masters course and possibly will not endwith it. Significant experiences aredescribed in relation to three studiesperformed at the beginning of the research: Pele na água, Relógio Pélvico and Borboleta Pélvica. Pele na água shows a relational work found between the performance and the engraving. Relógio Pélvico and Borboleta Pélvica depart from a place of anatomy and are developed through encounters with people interested in the knowledge of somatic-performative movement and creation. In the midst of the relationships lived in these processes, a sentimentidea called Sim-eu was created, which deals with the creative power between people who bet on the integration of themselves and the other.

Na situação estudada há muitos elementos com comportamento estocástico, que podem influenciar na produtividade da linha, além da diversidade de insumos que abastecem a montagem, o que torna o balanceamento da linha uma tarefa complexa e favorece o uso da Simulação como procedimento de solução. Na modelagem conceitual do problema estudado adotou-se o método IDEF-SIM e para a simulação foi utilizado o software ProModel®. Como resultados tem-se um modelo conceitual e implementado para uma linha de montagem que possibilitou informações interessantes sobre o problema, tais como: juntar funções de dois postos de trabalhos, eliminar excesso de movimentação e eliminar gargalos. / The overall objective of the research was to develop a simulation model discrete event to be applied to balancing an assembly line components in automotive company, seeking to increase line productivity and using lower amounts of inputs. In the situation studied for many elements with stochastic behavior, which may influence the productivity of the line beyond the range of products that supply assembly, which makes the balancing line a complex task and promotes the use of the simulation procedure as a solution. In conceptual modeling of the studied problem adopted the IDEF-SIM method and for the simulation we used the ProModel® software. As results has a conceptual model and implemented for an assembly line that has enabled interesting information about the problem, such as joining functions of two posts jobs, eliminate excess movement and eliminate bottlenecks.

<p>This thesis investigates how Ericsson AB should do to achieve fast and secure handover when roaming in a WLAN. It also provides a security analysis of the system that the wireless access point is part of. The reason for this is that Ericsson is selling an access point called the ABS 2200 aimed at the public hotspot market. </p><p>The premise was that they wanted a standardized way of handling the roaming issue. At the outset the 802.11F standard looked like a good alternative (in fact the only standardized alternative). Towards last stages of the work though, it was discovered that the 802.11F standard is no longer supported by IEEE. </p><p>Despite this fact, the conclusion is that secure and fast roaming can be attained if 802.11F is combined with the security standard 802.11i. </p><p>The security analysis concludes that Denial Of Service is a major threat to WLAN hotspots. It also points out the link between the access point and authentication server is the weakest link in the system. The recommendation is that this link receives an additional layer of protection through IPsec withESP. The algorithm recommendations for ESP are AES for confidentiality and SHA-1 for integrity. </p><p>This thesis can also be used as a primer on security in WLAN and contains an extensive glossary making it useful as a reference when reading 802.11 standards.</p>

<p>Much work has been done in simulating traditional cellular networks. But with the incoming of ad-hoc network technology, the next generation networks will employ hybrid network architectures using both cellular and ad-hoc networking concepts. </p><p>We investigate how to create a simulator being able to simulate a hybrid wireless network. This involves setting up a cellular network and an ad-hoc network respectively. However, the most important thing is how to integrate them seamlessly. </p><p>Fortunately, there has already been a simulator called SIMRA which simulates a UMTS cellular network. Therefore, this thesis work is greatly simplified as how to extend and improve SIMRA to implement a simulator for hybrid wireless network. We selected J-sim as the developing platform for our simulator and our development was greatly based on the wireless package provided by the latest version of J-sim. </p><p>To evaluate the new simulator, different resource allocation algorithms were run against it and the results were compared to those generated by earlier extensions to SIMRA under the same simulation settings. It showed that the resource allocation algorithms behaved similarly under the hybrid wireless network environment. Nevertheless, there are some discrepancies in behaviors of algorithms used for evaluation that still need to be studied.</p>

Conventional TCP is window based, which exploits the sliding window mechanism to conduct the flow control. It increases the sending window additively and decreases the sending window multiplicatively in response to successful transmission and, packet loss/timeout events respectively. While the mechanism works quite well in normal networks, TCP can hardly reach the ideal bandwidth utilization in long fat networks (LFNs) due to long delay and bursts of packet losses. Besides, as wireless and mobile computing has become popular today, packet loss in such networks may occur due to noise, interference and handoff across different domains. TCP could not react to different situations effectively as it sees all packet losses as an indication of network congestion. In this thesis, we proposed a new transmission control mechanism called Active Rate Anchoring TCP (ARCH-TCP). In ARCH-TCP, we explicitly integrate bandwidth measurement into TCP to solve the aforementioned problem. Specifically, we exploit packet-pair measurement to quickly estimate bandwidth share and then RTT variation is observed to compensate measurement error. We built the model in J-Sim network simulator to evaluate the effectiveness of our proposal. We found that ARCH-TCP can react to network conditions quickly and precisely in both wired and wireless networks and both in the normal networks and LFNs.
