Diseño de una red perimetral de internet de gran escala basada en el protocolo BGP sistemas autónomos y prefijos IP propios / Design of a large and scale internet perimeter network based on the BGP protocol autonomous systems and IP prefixesMartinez Corazao, Michael Marcelo 17 April 2021 (has links)
Muchas compañías en nuestro país están transformando sus procesos, digitalizando sus productos y servicios para el alcance de los clientes, desde cualquier lugar y sin la necesidad de acercarse presencialmente a una oficina o local, sin embargo, el principal medio para el acceso a dichos servicios es Internet, además, la contratación de este servicio genera una dependencia directa con los proveedores de Telecomunicaciones. Hoy en Perú mas del 80% de la población tiene acceso a Internet, sin embargo, la experiencia en el uso no necesariamente es la mejor, ya que, se presentan muchas incidencias e interrupciones en el servicio, por ello las compañías se ven obligadas a establecer estrategias superlativas con el objetivo de mantener sus servicios o productos digitales siempre disponibles; dicho esto, este proyecto tiene como objetivo diseñar una arquitectura de Internet que, elimine esa dependencia de los proveedores de Telecomunicaciones y, utilizar esta capacidad con el objetivo de darle mayor flexibilidad a la red de datos, potenciar los niveles de continuidad, reducir costos y los más importante mantener los servicios siempre disponibles. La estrategia se basa en la operación de la red de datos, a través, de un sistema autónomo y prefijos IP públicos independientes, además utilizar el protocolo BGP para establecer las sesiones con los proveedores y no depender de ellos directamente, es decir la gestión de la capa perimetral ahora depende directamente de nuestra organización objetivo y no de los proveedores. / Many companies in our country are transforming their processes, digitizing their products and services for the reach of customers, from anywhere and without the need to go to the office, however, the necessary service to access is Internet, also, the hiring of this service generates a direct dependence with the Telecommunications providers. Today in Peru more than 80% of the population has access to the Internet, however, the experience in use is not necessarily the best, because there are many incidents and interruptions in the service, therefore companies are forced to establish superlative strategies in order to keep your digital services or products always available; Having said that, this project aims to design an Internet architecture that eliminates that dependence on telecommunications providers and uses this capacity in order to give greater flexibility to the data network, enhance continuity levels, reduce costs and the most important to keep the services always available. The strategy is based on the operation of the data network, through an autonomous system and independent public IP prefixes, in addition to using the BGP protocol to establish sessions with providers and not directly dependent on them, that is, management the edge layer is now directly up to our target organization and not the vendors. / Tesis

Design of Perimeter Walls in Tubed Mega Frame Structures / Dimensionering av omslutande tvärväggar i TMF-konstruktionerFall, Niklas, Hammar, Viktor January 2014 (has links)
The Tubed Mega Frame is a new concept for constructing high-rise buildings,based on the idea of moving the main bearing system to the perimeter of thebuilding by using a number of large hollow columns, mega tubes, connected byperimeter walls at certain levels. The concept is under development by Tyréns ABand has not yet been implemented in reality. This thesis is part of the ongoing workprocess and has the aim of shedding light on the issues and problems with the newconcept when it comes to the perimeter walls. The perimeter walls are an essential part of the Tubed Mega Frame structure sincethey provide the main lateral stability of the structure by connecting the mega tubesand transferring lateral loads between them. It is therefore of big importance thatthe walls are designed and constructed to withstand all the loads they wouldpossibly be exposed to.In this thesis a perimeter wall in a prototype building of the Tubed Mega Framehave been analysed, designed and tested using non-linear FE-analysis in the pursuitof create a better understanding in how the perimeter walls works and should bedesigned. To begin with, a global analysis was performed to obtain the forces acting on themost critical perimeter wall. The stresses in the wall were then analysed in order tocreate an appropriate strut-and-tie model used to determine the reinforcementdesign for the specified perimeter wall. The perimeter wall was designed for amaximum shear force of 14.5 MN and corresponding moment of 87 MNm usingstrut-and-tie model according to American standards, ACI 318-11. The final step was to verify the design using the non-linear FE-analysis programATENA. A model of the reinforced wall was analysed with two different loadcases; one were the resistance was determined by unidirectional deformation untilfailure and one were the effects of cyclic loading was considered by initialdeformation corresponding to service loads prior to failure loading. The resistanceobtained from the first load case was 46.8 MN and for the second 19.1 MN usingmean values for material properties. In order to obtain a design resistance of the wall in the non-linear analysis, a globalsafety factor was determined by using the ECOV method. The design resistance were 39.9 and 13.5 for the two load cases respectively. / Tubed Mega Frame (TMF) är ett nytt koncept för att bygga höghus som bygger påidén om att flytta det bärande systemet till omkretsen av byggnaden med hjälp avett antal stora ihåliga pelare, megatuber, anslutna med omslutande tvärväggar påvissa våningsplan. Konceptet är under utveckling av Tyréns AB och har ännu integenomförts i verkligheten. Detta examensarbete är en del i den pågående processenoch målet är att belysa frågor och problem som finns med det nya konceptet närdet gäller de omslutande tvärväggarna. De omslutande tvärväggarna är en vital del av Tubed Mega Frame eftersom debidrar till huvudsakliga sidostabiliteten i byggnaden genom att sammankopplamegatuberna och överföra horisontalkrafter mellan dem. Det är därför av stor viktatt väggarna är konstruerade och tillverkade för att stå emot alla de belastningarsom de skulle kunna vara utsatta för. I detta examensarbete har en tvärvägg i en prototypbyggnad för Tubed MegaFrame analyserats, dimensionerats och testats med syftet att bidra till en bättreförståelse för hur tvärväggarna fungerar och bör utformas. Till att börja med har en global analys utförts för att erhålla de krafter som verkarpå den mest kritiska tvärväggen. Spänningarna i väggen analyserades sedan för attskapa en lämplig fackverksmodell som sedan användes för att bestämmaarmeringsutformning för den specificerade tvärväggen. Väggen dimensioneradesför en maximal tvärkraft på 14,5 MN och ett motsvarande moment på 87 MNmgenom att använda fackverksmetoden enligt amerikanska standarder, ACI 318-11. Det sista steget var att kontrollera konstruktionen med hjälp av det ickelinjära FE-analysprogrammet ATENA. En modell av den armerade väggen analyserades medtvå olika lastfall. I det första lastfallet genom att i en riktning deformera väggen tillbrott. I det andra lastfallet beaktades tidigare uppsprickning genom att först belastaväggen med en deformation motsvarande dess brukslast och sedan belasta väggen imotsatt riktning tills brott uppstod. Bärförmågan var 46,8 MN och 19,1 MN förrespektive lastfall, beräknat med medelvärden för materialegenskaper. För att erhålla en dimensionerande bärförmåga för väggen ur den ickelinjäraanalysen bestämdes en global säkerhetsfaktor med hjälp av ECOV-metoden.Dimensionerande bärförmåga var 39,9 MN och 13,5 MN för respektive lastfall.

[en] CRITICAL AND MEANINGFUL MATHEMATICS: AN EXPERIENCE WITH GEOMETRY IN THE YOUTH AND ADULT EDUCATION PROGRAM (PEJA) / [pt] MATEMÁTICA CRÍTICA E SIGNIFICATIVA: UMA EXPERIÊNCIA COM A GEOMETRIA NO PROGRAMA DE EDUCAÇÃO DE JOVENS E ADULTOS (PEJA)LUIZ CARAHU DA CUNHA NETO 30 April 2020 (has links)
[pt] Este trabalho é fruto de reflexões voltadas para o incentivo do ensino crítico
e significativo de matemática na educação básica e defende a utilização da
tecnologia neste espaço. Em especial são tratados conteúdos relativos ao cálculo de
perímetros, áreas e volumes para o público do Programa de Educação de Jovens e
Adultos (PEJA). O PEJA está vigente na Prefeitura da Cidade do Rio de Janeiro
desde 1984 e atende uma parcela considerável da população que, por algum motivo,
não pôde concluir o ensino regular na idade escolar prevista. Pretendeu-se com as
reflexões apresentadas nos capítulos iniciais, aproximar o cotidiano do aluno ao
mundo da matemática, mostrar o quanto aspectos geométricos estão presentes em
suas vidas e promover a criticidade através do incentivo de debates e troca de
experiências e saberes. A geometria exige um olhar cuidadoso no que diz respeito
à compreensão do espaço e das formas de objetos. Buscou-se, portanto, o
desenvolvimento de métodos adequados ao público que estimulassem esse olhar.
As reflexões desenvolvidas geraram um produto educacional constituído de uma
sequência de atividades criadas e aplicadas junto a alunos do PEJA. As atividades
e os resultados de suas aplicações estão expostos nos capítulos finais do trabalho.
Espera-se que o presente estudo possa colaborar com outros professores
interessados em criar caminhos comprometidos com o intuito de promover na
educação básica, cada vez mais, uma educação crítica e significativa que incentive
a autonomia para todos. / [en] This study is the result of thoughts and reflections focused on the
encouragement of a critical and meaningful teaching of Mathematics on basic
education level and advocates the use of technology in classroom. In particular,
topics related to perimeter calculations, areas and volumes are covered, to the public
of the Young and Adults Education Program. This Program is in force at the Rio de
Janeiro s City Hall since 1984 and meets a considerable portion of the population
which, for some reason, could not complete regular education on the predicted age.
It was intended, through the thoughts and reflections presented in the first chapters
to bring the students daily life closer to the Mathematics World, showing that
geometrical aspects are common in their lifes. It was intended too, also, to promote
criticality through the encouragement of debates and exchange of experiences and
knowledge. Geometry requires a careful look with regard to the space
comprehension and the objects form. Therefore, we sought the development of
suitable methods that stimulate that look, to the public. The thoughts and reflections
developed generated an educational product consisting in a sequence of activities
created and applied to PEJA students. The activities and their results are shown in
the final chapters of this study. We hope that this study can collaborate with other
teachers, interested in creating compromised paths, in the Basic Education, to
promote a critical and meaningful education that encourages the autonomy of all.

A Versatile and Ubiquitous Secret Sharing: A cloud data repository secure accessAdeka, Muhammad I., Shepherd, Simon J., Abd-Alhameed, Raed, Ahmed, N.A.S. January 2015 (has links)
No / The Versatile and Ubiquitous Secret Sharing System, a cloud data repository secure access and a web based authentication scheme. It is designed to implement the sharing, distribution and reconstruction of sensitive secret data that could compromise the functioning of an organisation, if leaked to unauthorised persons. This is carried out in a secure web environment, globally. It is a threshold secret sharing scheme, designed to extend the human trust security perimeter. The system could be adapted to serve as a cloud data repository and secure data communication scheme. A secret sharing scheme is a method by which a dealer distributes shares of a secret data to trustees, such that only authorised subsets of the trustees can reconstruct the secret. This paper gives a brief summary of the layout and functions of a 15-page secure server-based website prototype; the main focus of a PhD research effort titled ‘Cryptography and Computer Communications Security: Extending the Human Security Perimeter through a Web of Trust’. The prototype, which has been successfully tested, has globalised the distribution and reconstruction processes. / Petroleum Technology Development Fund

An examination of the impact of residential security measures on the incidence of residential burglary in two selected northern suburbs of Johannesburg: a security risk management approachOlckers, Casparus 30 June 2007 (has links)
Motivation
This project was of specific importance to the private security industry, victims of residential burglary, community policing forums and the South African Police Service in providing detailed information regarding recommendations of how to manage and combat residential burglary in two selected northern suburbs of Johannesburg.
Problem statement
Residential burglary is categorised in the top three highest reported crimes according to the official South African Police Service statistics for the 2006/7 financial years.
A series of victim interviews, docket analysis, case plotting and residential security audit surveys were conducted to determine the extent (or lack thereof) of security measures at a burgled residence in the selected area.
Approach
Field data was collected through docket analysis, plotting crime scenes (descriptive mapping), victim interviews and residential security audit surveys.
Results
The majority of victims of burglary interviewed did not have the minimum security system (integrated measures) in place. Those victims, who had security measures, appeared not to have made or implemented effective use of them.
Conclusion
Security at a residence extends beyond just the immediate house area and the focus (security risk assessment) should start with the immediate neighbourhood (community) area working inwards towards the property perimeter (boundary), inner perimeter (garden area) and then finally the immediate house area. / CRIMINOLOGY / MTECH: SECURITY RISK MAN

Curvas padrão pôndero-estatural de portadores de Síndrome de Down procedentes da região urbana da cidade de São Paulo / Growth charts (standard grown curves) of children with down Syndrome deriving from São Paulo\'s Urban areaMustacchi, Zan 29 November 2002 (has links)
De fato, por não existir um levantamento antropométrico de crianças com síndrome de Down no Brasil, foi realizado em São Paulo um estudo biométrico prospectivo que permitiu a elaboração de curvas antropométricas avaliando taxas de peso, estatura e perímetro cefálico elaboradas por tabelas e gráficos com valores lapidados de 4 percentis de dois grupos etários de ambos os sexos divididos de 0-24 meses e de 2-8 anos respectivamente.o estudo considerou e excluiu, quando pertinente, fatores ambientais ou genéticos paralelos que eventualmente pudessem interferir nas variáveis avaliadas. A ampla revisão bibliográfica e a comparação dos dados antropométricos permitiram enfatizar a importância de curvas padrões nacionais para estatura, peso e perímetro cefálico de crianças com síndrome de Down, facilitando o diagnóstico diferencial entre outros comprometimentos clínicos, auxiliando na intervenção clínico-Iaboratorial, na prevenção e acompanhamento médico. / Considerint that there is any anthropometrical evaluation in children with Down\'s syndrome in Brazil, the objective of this prospective biometric investigation was to construct anthropometrical curves for weight, stature and cephalic perimeter in children with Down\' s syndrome living in São Paulo urban area. Ali measurements were obtained from January 1980 to December 1999. Ali height or cephalic perimeter values 10% below or above and weight values 16% below or above of the 1st and 3rd quartile were excluded. Tables for each sex during 0-24 months and 2-8 years were presented in mean, standard deviations, percentiles and quartiles and graphics were presented in percitiles. Environmental and genetic factors associated that could interfere in development were identified and the proband excluded from the sample. The employing of a national pattem curve of stature, weight and cephalic perimeter for individuaIs with Down\' s syndrome would be useful in differential diagnosis among other clinical disorders associated to this genetic malformation providing better clinical intervention and prevention of comorbidity.
