Full textAbstract:
Thesis (MSc (Radiography))--Cape Peninsula University of Technology, 2019Background: Hospital-acquired infections (HAIs) known as nosocomial infections are a major challenge within the health-care environment. Although investment and time are continually spent on the eradication of HAIs, the problem still exists. The European Centre for Disease Prevention and Control (2015) reported that annually, 4,100,000 patients in Europe acquire additional diseases during their stay in the hospital resulting in 14,700 deaths. Nosocomial infections therefore contribute to the imbalance between resources for the management of hospitals. This is a particular challenge in developing countries like those in Sub-Saharan Africa, of which Ghana is part and, where very limited resources are available for the high volume of patient output. Radiology is a high technology service department that provides imaging to numerous inpatients and outpatients on a continuous basis. This means that items in the radiology department may serve as possible reservoirs for the transmission of nosocomial pathogens from one individual to another. Where Radiology resides within a health-care system that is unable to give adequate attention to the spread of nosocomial infections or even to proper infection control measures, HAIs becomes a real possibility. Aims: The aim of this study was to determine whether radiology imaging equipment and accessories for general radiography are possible fomites of nosocomial pathogens. The study also aimed at investigating the effectiveness of the disinfectant chemical agents (chlorine bleach/sodium hypochlorite and methylated spirits) used for cleaning surfaces at the research site. Furthermore, the study aimed to observe the cleaning procedures and practises by radiographers in general radiography. Methodology: The design of this research included an observational and an experimental phase. The study was conducted in the radiology department of a Teaching Hospital (TH) in Ghana. Swabbing, using wet sterile swab sticks was the method for sample collection. This was done on one occasion without cleaning of the selected x-ray equipment and accessories and another occasion after cleaning with the department’s preferred disinfectant chemical agents. The swab samples were then taken to the microbiology laboratory of the University of Ghana for culturing and identification. MacConkey and blood agar media were used to prepare the culture media. The prepared media were put into petri dishes and swab samples were inoculated onto the culture plates. Culture plates were then incubated for 24 hours, at a temperature of 37ºC. At the end of the incubation period, the culture plates were viewed macroscopically under a bright light, to identify any bacterial growth; according to their colony forming characteristics. Seven radiographers (n=7) were observed for a period of one month on the current cleaning procedures and practises in the radiology department. How thoroughly the equipment and accessories were cleaned (how much time spent per item) was recorded. Damp dusting (using cotton wool moistened with methylated spirits or chlorine bleach), cleaning equipment using methylated spirits or chlorine bleach after each contact with body fluid, hands washing after each patient using water and liquid soap, washing of hand randomly after patients (or in between patients) using water and liquid soap, were observed and recorded. Data was captured and analysed using the IBM SPSS Statistics Version 25. Results: The selected radiology imaging equipment and accessories swabbed were found to be contaminated with pathogens. Organisms identified were Staphylococcus aureus, Coagulase-negative staphylococci, Bacillus species(spp.), Shigella spp., Shigella sonnei., Klebsiella spp., Salmonella Paratyphi A, Salmonella Typhi, Providencia rettgeri, Enterobacter spp. and Citrobacter spp. Staphylococcus aureus was the predominate pathogenic isolate identified. A significant number of the Staphylococcus aureus and CoNS isolated was methicillin-resistant. Bacillus spp. was the predominant non-pathogenic isolate identified in the study. Statistically there was no significant difference (p=0.5835) between the total number of occurrences of bacterial isolates in both rooms after decontamination. The observation phase demonstrated that no documented protocol or infection control procedures were available. It was further observed that only one of the seven radiographers washed his/her hands after each patient, but that all radiographers practised hand washing and equipment cleaning when the procedure involved body fluid from patients. Conclusion: The research established that radiologic equipment and accessories were often exposed to pathogens and are therefore possible fomites of nosocomial pathogens. The effectiveness of the cleaning agents (methylated spirits and chlorine bleach) was not adequate. Radiographers partially practised infection control measures. Based on the findings of this study it recommended that a policy and procedure must be prepared and an awareness campaign/training of radiographers conducted. Other cleaning agents must also be investigated in a comparative study to determine the most effective agent (but still affordable within the resource constrained environment).

Resumo: Este estudo teve como objetivo o projeto e a construção de um fogão doméstico alimentado continuamente por etanol, com a avaliação de rendimento de queima. O Brasil como o maior produtor de etanol, produzido a partir da cana-de-açúcar e elevado grau de desenvolvimento tecnológico, tornou esse combustível uma opção viável para substituição do GLP (gás liquefeito de petróleo) em fogões domésticos. Para a utilização do etanol foram necessários estudos para modificações tanto na forma de armazenamento, como no desenvolvimento de um novo design do queimador, visando uma queima compatível ao combustível já utilizado. Foram feitas análises termodinâmicas, a fim de descobrir os parâmetros mais relevantes na modificação. A partir dessas modificações foram desenvolvidos dois queimadores que se encaixam nas categorias semirrápido e auxiliar, com eficiências de 69% e 72% respectivamente, enquadrando ambos os queimadores na categoria A de eficiência

Resumo: É proposta uma metodologia de projeto e de calibração de um medidor de fração de vazio para escoamento de gás e líquido operando com o princípio de impedâncias elétricas baseado em simulação numérica. O desenvolvimento do sensor é feito utilizando-se de um software de volumes finitos para a otimização heurística da geometria dos eletrodos e também para a criação de uma curva de mapeamento do sinal para fração de vazio de acordo com as características elétricas do fluido em questão, ou seja, características capacitivas (óleo, gás), resistivas (água) ou ambas. Utilizando o conceito de similaridade entre modelo e protótipo foi possível reduzir os resultados computacionais a simples expressões algébricas que relacionam diretamente a fração de vazio com a voltagem do circuito e estender este resultado para tubulações de quaisquer diâmetros. Testes estáticos e dinâmicos são feitos com o propósito de validar o estudo computacional e verificar o desempenho do sensor operando com diferentes padrões de escoamento
Abstract: A methodology for design and calibration of a void fraction meter for gas and liquid flow operating on the principle of electrical impedance is developed based on numerical simulation. The sensor development is done using a finite volume software. The numerical analysis allowed a heuristic geometry optimization of the electrodes and also created a mapping curve for the void fraction signal according to the electrical characteristics of the fluid in consideration, ie, capacitive (oil, gas), resistive (water) or both. Using the concept of similarity between model and prototype it was possible to reduce the computational results to simple algebraic expressions that relate directly the void fraction with the voltage output and extend this result to pipes of any diameter. Static and dynamic tests were done in order to validate the computational study and verify the performance of the sensor operating with different flow patterns

Abstract: Many CRSs models are available in the market; several are developed to accommodaté different mass group children. There is overlap among the mass groups and as consequence the same child can use a different mass group CRS. The purpose of this paper is to compare the dummy kinematic in a dynamic test similar to ECE R 44 with the same CRS design installed according to Group I (five points harness) and installed according to Group II (vehicle's three point safety belt). To support the conclusions the data of CRS Certification test for Group I and II were used. The chosen CRS is certified for Brazilian market according to INMETRO administrative rule 38 and is anchored to the vehicle by its three point safety belt according to the CRS manufacturer's recommendation. The dynamic tests were performed on Sled subjected to the ECE R 44 standard acceleration vs. time curve. The harness loads and vehicle safety belt loads will be gathered and dummy kinematic were recorded with high speed digital cameras. The results are tabulatéd and compared with focus on the relevant performance differences. This study conclude that dynamic dummy response depend on the CRS design used to install the device to the vehicle and considering the lower ATD head excursion, the lower injuries at head, pelvis, pubic and chest acceleration the tested CRS installed according to Group II (five points harness) present better safety performance on dynamic tests than tested CRS installed according to Group I (vehicle's three point safety belt)

In geotechnical problems of flow, the main variables that characterize the hydraulic behavior in an unsaturated medium, is the water retention curve (WRC) and the hydraulic conductivity function (HCF) of the soil. Experimental determination of these properties is generally time-consuming and costly, leading professionals to use simplifications that may eventually prejudice the projects, increasing costs and compromising safety. In order to help reduce this difficulty, in this thesis, a procedure and equipment adapted into a small centrifuge commonly used in medical applications were developed, allowingto obtain hydraulic properties (WRC and HCF) of soils in a much shorter time. The technique involves exposing soil samples initially saturated to a circular motion, resulting in a centripetal acceleration and a mass force sufficient to overcome capillarity and force fluid drainage. The equipment is able to simultaneously obtain four WRCs and four HCFs. To verify the performance of the new equipment, two soils with different characteristics, one clayey sand (SC) and a high plasticity clay (CH), were tested. The WRCs obtained with the centrifugewere compared with ones obtained by traditional methods offilter paper and pressure plate. Comparisons were appropriate up to suctions of the order of 500 kPa, the current limit of the equipment developed. For soils that require higher suctions, a proposal was made to add to the data obtained with the centrifuge, a point given by the filter paper close to the residual moisture of the soil. The methodology for obtaining the HCF is of the transient type using multiple steps, in which one applies an increase in the matric suction value, and measure the volume of water that flows out of the specimen. The HCFs obtained by centrifugal method were compared with the one given by the theoretical model of van Genuchten- Mualen and points directly measured with a flexible wall permeameter and constant flow application developed by Guimarãeset. al. (2008).Comparisons were good, especially for the thicker texture soil (SC). The maximum times to obtain the WRCs and HCFs were two days for soil SC and three days for soil CH. The methodology is efficient and reduces, significantly, the time required to obtain hydraulic properties of soils.
Em problemas geotécnicos de fluxo, as principais variáveis que caracterizam o comportamento hidráulico em um meio não saturado, são a curva de retenção de água (CRA) e a função de condutividade hidráulica (FCH) do solo. A determinação experimental destas propriedades é, geralmente, demorada e onerosa, levando os profissionais a utilizar simplificações que, eventualmente, podem prejudicar osprojetos, aumentando os custos e comprometendo a segurança. No sentido de contribuir para diminuir esta dificuldade, desenvolveu-se nesta tese, um procedimento e aparatos que, adaptados em uma centrifuga de pequeno porte comumente usada em aplicações médicas, permitem obter as propriedades hidráulicas (CRA e FCH) de solos em um tempo bem menor. A técnica consiste em expor amostras de solos inicialmente saturadas a um movimento circular, gerando uma aceleração centrípeta e uma força de massa suficiente para vencer as forças capilares e forçar a drenagem do fluido. O equipamento é capaz de obter simultaneamente quatro CRAs e quatro FCH. Para verificar o funcionamento do novo equipamento, foram utilizados dois solos com características distintas, uma areia argilosa (SC) e uma argila de alta plasticidade (CH). As CRAs obtidas por meio da centrífuga foram comparadas com as CRAs obtidas pelos métodos tradicionais do papel filtro e da placa de pressão. As comparações foram adequadas até sucções da ordem de 500 kPa, atual limite do equipamento desenvolvido. Para solos que necessitem de sucções mais altas, foi apresentada uma proposta de acrescentar aos dados obtidos com a centrífuga, um ponto obtido por meio do papel filtro com umidade próxima da residual. A metodologia para obtenção da FCH é a do regime transiente por passos múltiplos, na qual se aplica um acréscimo no valor da sucção matricial e mede-se o volume de água que sai do corpo de prova. AsFCHs obtidas pelo método centrífugo foram comparadas com ado modelo teórico de van Genuchten-Mualen e com pontos medidos diretamente com um permeâmetro de parede flexível e aplicação de vazão constante desenvolvido por Guimarães et. al. (2008). As comparações ficaram boas, principalmente, para o solo com textura mais grossa (SC). Os tempos máximos para obtenção das CRAs e FCHs foram de dois dias para o solo SC e de três dias para o solo CH. A metodologia desenvolvida se mostrou eficiente, reduzindo substancialmente o tempo necessário para se obter as propriedades hidráulicas de solos.

Resumo: Esta dissertação visa comparar o desempenho de um sistema convencional de proteção de ocupantes (sistema de retenção) em um veículo de passeio com um sistema pre-crash, considerando ocupantes de três tamanhos diferentes. O termo pre-crash significa que pode ocorrer o disparo do air-bag e pré-tensionador antes do instante de impacto enquanto que no sistema convencional o disparo ocorre sempre após o impacto. Com esta finalidade foi utilizado um modelo de simulação desenvolvido no programa `Madymo¿ combinado ao programa de otimização multidisciplinar `Mode-Frontier¿. Este modelo corresponde à parte do veículo que envolve o motorista e é constituído por parte da carroçaria, assento, coluna de direção e o sistema de retenção. Todo o modelo está sujeito a uma curva de aceleração que representa um impacto frontal contra uma barreira rígida a 50 km/h. São utilizados três tamanhos padronizados de ocupantes representados por bonecos (dummies) que possuem sensores em certas partes do corpo com a finalidade de identificar os índices biomecânicos resultantes do impacto. Estes índices biomecânicos identificam o nível de carga sobre estas partes do corpo e podem ser comparados com critérios estabelecidos em norma. Os três tamanhos de ocupante são definidos da seguinte forma: 5%, 50% e 95%. Onde 5% representa a parcela de 5% da população de menor estatura, 50% representa uma estatura equivalente à média da população e 95% a estatura que é maior que 95% da população. Este padrão é definido de acordo com o tamanho da população americana da época em que estes dummies foram desenvolvidos. O trabalho é dividido em três etapas. Na primeira é utilizado o programa de otimização para dimensionar um sistema de retenção que seja ideal para o 'dummy' tamanho 50%. A partir dos parâmetros determinados para o sistema de retenção são avaliados e comparados os índices biomecânicos dos ocupantes de tamanhos 5% e 95%. O objetivo é demonstrar os riscos a que os ocupantes de dimensões fora do tamanho 50% estão sujeitos. Posteriormente são encontrados, também por meio de algoritmo de otimização, os parâmetros do sistema de retenção que são ideais para os ocupantes 5% e 95%. Novamente é feita uma comparação dos resultados. Por fim é feito um procedimento similar considerando a possibilidade de adiantamento no disparo de dois dispositivos do sistema de retenção: air-bag e pré-tensionador. Novamente é utilizado o algoritmo de otimização para encontrar os parâmetros ideais do sistema de retenção para o ocupante de estatura 50%. Neste caso pode-se verificar se ocorre a melhora dos índices biomecânicos para o ocupante de tamanho 50% comparando-se com os resultados obtidos em um sistema de retenção convencional. Porém, neste caso, o aspecto mais importante deste trabalho é verificar se o adiantamento no tempo de disparo possibilita de redução do risco de ferimentos também para os ocupantes com dimensões 5% e 95% mesmo utilizando-se um sistema de retenção dimensionado para o ocupante de tamanho 50%.

Abstract: This dissertation aims to compare the performance of a conventional occupants protection system in a passenger vehicle with the performance of a pre-crash system, considering occupants of three different sizes. The term pre-crash means that the firing of the airbag and pretensioner may occur before the instant of impact, while in the conventional system the trigger always occurs after impact. With this purpose a simulation model was developed in the software 'MADYMO' combined with the multidisciplinary optimization software 'Mode-Frontier'. The frontal region of the passengers compartment, the seat, the steering column and the restraint system are modelled. The whole model is subject to an acceleration curve that represents a frontal impact against a rigid barrier at 50 km/h. Three standard occupant sizes represented by dummies are used. They have sensors in certain parts of the body with the purpose of identifying the biomechanical results from an impact. The level of biomechanical loads on parts of the body can be compared with the criteria established in the regulations. The three sizes of occupant are defined as follows: 5%, 50% and 95%. Where 5% is the share of 5% of the population with smaller stature, 50% represents a height equivalent to the average of the population and 95% height that is greater than 95% of the population. The default size is set according to the size of the U.S. population at the time that these dummies were developed. The work is divided into three stages. The first uses an optimization program to obtain a restraint system that is ideal for the dummy size 50%. From the parameters determined for the restraint system the biomechanical indices of occupant sizes 5% and 95% are evaluated and compared. The purpose is to demonstrate the risks to which occupants of dimensions out of size 50% are subject. In the second stage the parameters of the restraint system which are ideal for the sizes 5% and 95% are found, also by means of the numerical optimization algorithm. A comparison of the results for the dummy 5% with parameters for 5 and 50% is made. Also a comparison of the results for the dummy 95% with parameters for 95 and 50% is made. Finally, in the third stage, a similar procedure is done considering the advance in the firing time of two devices from the restraint system: air-bag and pretensioner. Again the optimization algorithm is used to find the optimal parameters for the restraint system considering the occupant height 50%. In this case it is checked whether there are improvements of biomechanical indexes for the occupant size 50%, comparing with the results obtained in a conventional restraint system. Here we reach the most important aspect of this work, which is checking if the advance in firing time results in a reduction of the risk of injury also for occupants with dimensions 5% and 95%, even using a retention system sized for the occupant size 50%.

Resumo: As indústrias de sementes e alimentícias têm sofrido pressões do mercado para produção de matéria-prima segura em relação às contaminações físicas, químicas e biológicas. Um caminho inverso começa a ser percorrido, no qual se tira o foco apenas do controle da qualidade do produto final, iniciando-se o rastreamento de toda a cadeia produtiva, para que os processos possam ser controlados e medidas preventivas possam ser tomadas para melhoria da qualidade e diminuição dos prejuízos. Este modelo exige que normas e padrões sejam seguidos a fim de assegurar a inocuidade dos alimentos. Contudo, estas normas são eficientes quando utilizadas em sistemas que tenham algum nível de organização, mas o que se observa é que os produtores rurais não dominam as ferramentas gerenciais comprometendo o controle da qualidade. Um fator que é observado dentro de unidades de beneficiamento (UB) de grãos e de sementes é a variabilidade do produto recebido, em relação aos aspectos físicos e sanitários. Assim, com a finalidade de avaliar o processo de beneficiamento de milho, adequando-se ainda mais às exigências do mercado consumidor e da legislação, foi desenvolvido este trabalho conjunto entre a COPLACANA (Cooperativa dos Plantadores de Cana do Estado de São Paulo), sediada no município de Piracicaba-SP, FEAGRI/UNICAMP, ESALQ/USP e CATI. Foram realizados levantamentos para determinação dos pontos críticos de controle (PCCs) através da avaliação do sistema de beneficiamento de grãos de milho da UB da COPLACANA. Ao final do levantamento, foi observada a variabilidade do material recebido quanto aos grãos avariados e, baseado nesta variabilidade da matéria-prima, testou-se se as sujidades influenciariam nas propriedades físicas dos grãos. Buscando alternativas seguras na manipulação e para o meio ambiente, foi testado o efeito de óleos essenciais de espécies de Eucalyptus citriodora, E.camaldulensis e o efeito sinérgico na germinação de sementes. Ao final da pesquisa, foram determinados quatro pontos críticos de controle principais que deveriam ser trabalhados, sendo eles recepção, limpeza, secagem e armazenagem; já os pontos críticos de controle em relação à infraestrutura, ambiental e capacitação, são complementares. O grau de umidade dos grãos recebidos na UB apresentou umidade média de 18,5%, sendo o mês de fevereiro o mais crítico, o que pode ter influenciado na qualidade dos grãos em relação a grãos ardidos. O monitoramento nas fases de pré-colheita e colheita é recomendado para minimizar os danos imediatos e de ardidos nos grãos. Em relação às propriedades físicas, as porcentagens de sujidades influenciaram nos valores da massa aparente específica, velocidade terminal e o coeficiente de atrito para a chapa de concreto. O óleo essencial de Eucaliptus camaldulensis e sua interação com o óleo essencial de Eucaliptus citriodora não influenciaram negativamente na germinação das sementes. Os fungos Penicillium spp e Fusarium sp. Foram controlados pelos óleos essenciais de E. camaldulensis e E. citriodora
Abstract: The seed and food industries have suffered from market pressures to produce safe raw material in relation to physical contamination, chemical and biological weapons. A reverse path starts to go, in which it takes the focus only on the quality control of the final product, starting tracking the entire production chain, so that processes can be monitored and preventive measures can be taken to improve quality and reduction of losses. This model requires that rules and standards are followed to ensure food safety. However, these Standards are effective when used in systems that have some level of organization, but what is observed is that farmers do not dominate the managerial tools compromising quality control. One factor that is observed within processing units (UB) of grains and seeds is the variability of the product received in the physical aspects and health. Thus, in order to evaluate the process of maize improvement, adapting to the demands of even the consumer market and the legislation was developed this collaborative effort between the COPLACANA (Cane Growers Cooperative of State of São Paulo) based in Piracicaba- SP, FEAGRI /UNICAMP, ESALQ / USP and CATI. We raised the critical control points by evaluating the system of processing of corn from the UB COPLACANA. At the end of the survey, we observed the variability of the material received regarding damaged grains and decided to check the influence of dirt on the physical properties of the grains. Seeking alternatives for safe handling and the environment, it was decided to test the effect of essential oils of species of Eucalyptus citriodora, E.camaldulensis and synergistic effect on seed germination. At the end of the study, we determined four main critical control points that should be worked while they were receiving, cleaning, drying and storage, as the critical control points in relation to infrastructure, environmental and training are complementary. The moisture content of grain received at UB had average humidity of 18,5%, being the month February the most critical, which may have influenced the quality of grains for burning grains. The monitoring in the pre-harvest and harvest is recommended to minimize the immediate damage and rot in the grains. Regarding physical properties, the percentages of dirt influenced by the values of apparent specific mass, terminal velocity and the coefficient of friction for the concrete plate. The essential oil of Eucalyptus camaldulensis and this interaction with essential oil of Euclyptus citriodora had no effect germination. Penicillium spp and Fusarium sp were controlled by the essential oils of E. camaldulensis and E. citriodora

Resumo: Integridade de poço pode ser entendida como sua capacidade de evitar vazamentos para o meio ambiente e é uma importante característica de um poço de petróleo. Uma das formas de evitar vazamentos durante a fase de produção é realizar intervenções de manutenção que conservem os poços em situações seguras e com barreiras de segurança sobressalentes. A previsão de custos relativos às intervenções para manutenção deve ser levada em conta nas fases iniciais dos projetos de Desenvolvimento da Produção, quando se planeja e se avalia técnica e economicamente a campanha de construção de poços. Este trabalho apresenta uma metodologia para análise de integridade de poços de Desenvolvimento da Produção que considera a existência de estados intermediários, onde não há perda de integridade, mas o sistema poço encontra-se degradado, fundamentando-se nos conceitos de Conjuntos Solidários de Barreiras (CSB) propostos por Miura (2004) e em técnicas de Engenharia de Confiabilidade. A metodologia pode ser utilizada na previsão de recursos para as intervenções de manutenção de uma campanha de construção e operação de poços. Através do tempo esperado para falha de cada um dos CSB presentes na configuração de completação é possível se estimar quando o estado de integridade do poço passará a depender de um único Conjunto Solidário de Barreiras e qual a expectativa para que haja vazamento (ausência de CSB)
Abstract: Well integrity may be defined as its capability to prevent leaks to the environment and is therefore a very important feature for oil and gas wells. One way to avoid leaks during the well operation is to perform maintenance interventions, seeking to keep redundancy in the well's safety barriers. Cost assessment regarding the wells maintenance interventions shall be done during the initial phases of the Production Development project, when the wells construction campaign is both technically and economically evaluated. This work presents a methodology for petroleum wells integrity analysis considering the existence of intermediate stages, when the integrity has not been lost but the well is considered to be in a degraded status. The method is based on the Barrier Integrated Sets (BIS), proposed by Miura (2004, in Portuguese) and described by Miura et al. (2006 [1]), and on Reliability Engineering techniques. The methodology may be used for maintenance interventions resource assessment considering a well construction campaign. Through the computation of the mean time to failure of each BIS identified in the completion configuration it is possible to estimate when the well is in a degraded status, relying in a single Barrier Integrated Set and well the well is expected to leak (no BIS)

The design and assembly of automatic manufacture equipment are studied for bicycle accessories. The automatic manufacture, programmable logic controller (PLC) and mechatronics system are mainly developed for asymmetric rotation of manufacturing industry. The study designs an automatic manufacture that provided a rotation (flip-flop) function for bicycle accessories processing. The architecture PLC and mechatronics system consists of two servo motors, a stepper motor, a motor driver, a programmable logic controller (PLC), a human machine interface, a pneumatic solenoid valve, rotate the hand wheel and sensors. Two servo motors and a stepper motor are used for platforms of X and Z and a rotator, respectively. Experiment results show that the alignment of initial position can be reached by the stepper motor and a proximity sensor. In addition, PLC and motor driver can execute the rotations of 90 or -90 degrees of jig position. During the alignment control, the input pulse of step motor cannot be set smaller than 50 Hz, because the motor will produce shock. However, when the mechanism execute spin, the proximity sensors will give PLC signal that confirm air cylinder is not yet execute to prevent motor damage. Therefore, this study provides the fully automatic manufacture for bicycle accessories that designed according to the demand of market; it can provide different specifications and different shapes for asymmetric rotation of manufacturing industry.

Self-supporting lattice tower are being effective structural system by considering simple, light weight, easy fabrication and installation for supporting telecom equipment at elevated heights. With increase in demand of lattice towers, a critical review on approach for analysis is highly essential to ensure reliable and safe structures. In this paper, a comparative study is taken up on methodologies followed in both national standards (India, America) for assessment of wind loads on bare tower, linear accessories, discrete accessories along with design resistance of members and connections for Two different configurations – Square angular tower, Triangular Hybrid Tower. From the detailed analysis, it is concluded that, American standard (ANSI/TIA-222H) is using Ultimate windspeed for calculation of wind loads based on risk category of structure along with strength reduction factors based on criticality of components compared to Indian Standards (IS 875(Part 3)-2015, IS 802) which resulted lesser wind load on structure i.e., 30% in Square Tower (Oblique wind direction) and 23% in Triangular Hybrid Tower using ANSI/TIA-222H. Also, no major difference observed for calculation of member capacity and connection. Therefore, it is concluded that Tower weights approximately reduces by 10-15% based on Tower configuration using ANSI/TIA-222H compared to Indian Standards

Full textAbstract:
Operation of aircraft in hostile combat areas exposes the aircraft to risks of substantial damage or loss. Engine damage can occur as a result of impact or penetration by projectiles or fragments, or by ingestion of impact debris. The risk level depends upon threat, aircraft type, and mission. Historical evidence indicates that damage is often survivable. Aircraft can often be repaired and returned to service. The damaged engine may still be able to operate. Normal action is to remove and replace a damaged engine, but replacement engines may not be available. A procedure is needed at the operational unit level to immediately assess the exact nature and extent of engine damage, as well as rapid (perhaps nonstandard) engine repair procedures for use at forward locations. Such repairs can include reblading of compressors and turbines, replacement of cracked or broken gear cases or gears, and replacement or repair of accessories. Without repairs, the aircraft fleet may quickly lose its effectiveness. Performance indicators, gas path and oil debris quantity and size, and vibration levels can help identify the location and extent of damage. Vibration analysis with portable, computerized equipment can identify damage in the engine’s compressor and turbine rotating components, as well as cracked, broken, or otherwise damaged accessory drive gearboxes and accessories. Vibration analysis either provides an immediate indication that all vibration indicators are within limits, or localizes the damage to specific components for immediate replacement or repair at the operating unit location.

Abstract Efficiencies in operation are achieved largely in advanced failure analysis (FA) labs because routine steps or processes have been automated and the need for operator interaction minimized. Very few operators are required to run a fully automated, "lights out" type Fab. This paper discusses the various automation components which are available to labs as they look to streamline the FA process to support the Fab's ever increasing demand for more process data. These include iFast Automation software and automated recipes to create the thick lamella. The development of automation software and integrated accessories for FA equipment is now bringing more Fab-like activities and processes into the FA lab. As more and more automation moves into the FA lab, one should not be surprised in a few years to see very few operators sitting in front of tools with blinking green lights scattered throughout the lab.
