Resumo: Esta dissertação aborda uma proposta de metodologia de resolução de um problema de entregas que abrange a integração de dois problemas clássicos de Otimização Combinatória: o Problema de Carregamento de Container (PCC) e o Problema de Roteamento de Veículos (PRV). O problema específico analizado está na logística empregada no carregamento e entrega de eletrodomésticos (linha branca) vendidos à pessoa física. Para representar esta situação, assume-se um cenário fictício em que a empresa que vende os produtos possui um Centro de Distribuição de Produtos (CD) localizado na cidade de Curitiba e uma lista de doze possíveis produtos a serem vendidos. A partir desta lista foram gerados 160 pedidos diferentes para serem entregues em vinte endereços aleatórios localizados também na cidade de Curitiba. Para a resolução deste problema, apresenta-se uma metodologia baseada em formação de torres de caixas e um Algoritmo Bottom-Left para realizar o carregamento dos pedidos no compartimento de carga dos veículos e um Algoritmo Genético para realizar a otimização evolutiva da solução até que se encontre uma solução suficientemente próxima à solução ótima do problema, buscando diminuir, a cada geração, a distância total percorrida pelos veículos de entrega. Para demonstração e utilização desta metodologia, apresenta-se uma implementação dos algoritmos e técnicas de pesquisa operacional descritos acima para a resolução desenvolvida em linguagem de programação Microsoft Visual Basic. Utilizando-se esta implementação e o cenário construído para testes, obteve-se bons resultados em relação à distância total percorrida pelos veículos de entrega, com redução de 25% a 45% em relação às soluções iniciais aleatórias, sendo que em alguns casos, esta melhoria alcançou até 60%.

Discarded containers along roadways trap and kill small mammals. Significant numbers of small-mammal remains were found inside containers along Cherokee National Forest roads in remotes areas in a previous study. In this study, we investigated the effects of containers along a 5.5 km stretch of a more heavily used 2-lane forest service road in the Cherokee National Forest. 308 containers were collected from five different pull-off sites and within those were 13 small-mammal skulls representing 5 species of mammals including Sorex longirostris (Southeastern Shrew) and Synaptomys cooperi (Southern Bog Lemming), which are deemed species of greatest conservation need and in need of management by the Tennessee Wildlife Resource Agency. Like the previous study, it was found that glass bottles disproportionately trapped more small mammals than plastic or aluminum. Additionally, we also discovered the orientation and can openings for all available containers and found that containers oriented upslope (>15°) were significantly more likely to have a mortality impact than any other container orientation.

A study involving the movement of small-sized nursery plant containers was conducted using surface electromyography (EMG) to assess the effect that glove type has on forearm and shoulder muscle activation. A total of 24 participants were asked to move weighted nursery containers simultaneously with both left and right hands (one onegallon, two one-gallon and one three-gallon) from a floor location to a table located twenty feet away while wearing one of four glove treatments (1. No Glove; 2. Thick Leather; 3. Grip Assist Mechanics; 4. Thin Nitrile). Muscle activation was evaluated as a percentage of the participants’ maximum voluntary exertion (MVE). The results show no glove effect difference for the smaller pot configuration. With the larger container treatments, muscle activity was affected by glove treatment, specifically for the left and right flexor and extensor radialis muscles.

WebAssembly (Wasm) is an emerging technology for web development that has garnered significant popularity in web-based applications. It enables web browsers to execute codewritten in multiple languages seamlessly, delivering high performance across different platforms. With the introduction of The WebAssembly System Interface (WASI), facilitating the execution of Wasm beyond the confines of the web, Wasm is gaining traction in cloud computing as well. Recently, Docker introduced the support of running Wasm binaries in a container runtime using WasmEdge. This thesis investigates the performance implications and the usability benefits/issues of Wasm in container runtimes using WasmEdge compared to traditional Linux containers. To assess these aspects, two separate applications are utilized within the containers: the first application, inspired by the TPC-C benchmark, is created from the ground up to mimic a database workload, whereas the second application is WordPress, a widely adopted content management system. In evaluating the performance implications of Wasm containers, our experiments focus on gathering metrics relevant to container usage and management. These include image size, start-up times, CPU utilization, latency, and throughput differences between Wasm containers and traditional Linux containers. Additionally, we assess the usability of Wasm containers by examining aspects such as building, managing, deploying, portability, and language support. The finding of the thesis indicates that Wasm containers feature lower image sizes, up to 500% smaller image sizes than the Linux containers, and can improve cold-start times by 160%. However, due to the lack of multi-threading support of Wasm, the application performance becomes significantly degraded, resulting in increased latencies and reduced throughput compared to traditional containers. Furthermore, we underscore the portability advantage of Wasm containers over traditional ones in terms of usability. Nonetheless, the current language limitations of Wasm present more challenges than benefits compared totraditional containers.

A passagem da Operação Portuária das mãos do Estado para as mãos privadas, teve como objetivo básico preparar o defasado e caro sistema portuário brasileiro para o esforço de captação de industrias globalizadas através de incentivos fiscais e de infra-estrutura, assim como para o aumento das atividades de Comércio Exterior. Após sete anos da promulgação da referida Lei cabe a pergunta: estão os portos brasileiros preparados hoje para se integrarem na Cadeia Logística "porta a porta" nos padrões de qualidade exigidos e praticados pelo mercado internacional? Neste estudo de caso iremos ver os paradigmas de qualidade comuns na rede logística integrada e quais efetivamente o operador portuário privado dedicado à movimentação de containeres está aplicando, ou implantando, no âmbito do porto de Paranaguá.
