Trabalho de Conclusão de Curso (graduação)—Universidade de Brasília, Departamento de Desenho Industrial, 2013.Este relatório documenta o processo de elaboração de uma coleção de moda baseada no conceito “Bem”. O projeto foi desenvolvido na disciplina Diplomação em Projeto de Produto no curso de Desenho Industrial da Universidade de Brasília. Parte- se de uma inquietação pessoal sobre o sistema da moda e sua função enquanto estimulador de comportamentos. A partir disso é feita uma revisão teórica sobre a sociologia da moda, a conceituação de bem e suas relações, seguido de uma pesquisa imagética sobre temas relacionados, geração de croquis, seleção dos modelos finais, escolha de tecidos, modelagem e costura das alternativas finais e discussão sobre o resultado final. _______________________________________________________________________________ ABSTRACTThe present report doccuments the elaboration process of a fashion collection based on the concept of “Goodness”. This project was developed as a Product Design Bachelor degree project at the University of Brasilia. It begins with a personal uneasiness about the system of fashion and its fuction as it incites behaviour. From this, there is a theoretical study on fashion sociology, the concept of goodness and how they relate, followed by an imagetic research on related themes, the generating of sketches, selecting the final looks, choosing of fabrics, patterning and sewing of the final pieces and discussion of the final results

APAS: Application-Specific Accelerators for RLWE-based Homomorphic Linear Transformations

Recently, the application of multi-party secure computing schemes based on homomorphic encryption in the field of machine learning attracts attentions across the research fields. Previous studies have demonstrated that secure protocols adopting packed additive homomorphic encryption (PAHE) schemes based on the ring learning with errors (RLWE) problem exhibit significant practical merits, and are particularly promising in enabling efficient secure inference in machine-learning-as-a-service applications. In this work, we introduce a new technique for performing homomorphic linear transformation (HLT) over PAHE ciphertexts. Using the proposed HLT technique, homomorphic convolutions and inner products can be executed without the use of number theoretic transform and the rotate-and-add algorithms that were proposed in existing works. To maximize the efficiency of the HLT technique, we propose APAS, a hardware-software co-design framework consisting of approximate arithmetic units for the hardware acceleration of HLT. In the experiments, we use actual neural network architectures as benchmarks to show that APAS can improve the computational and communicational efficiency of homomorphic convolution by 8x and 3x, respectively, with an energy reduction of up to 26x as compared to the ASIC implementations of existing methods

Safety and Quality in the Agricultural Product Chain in Brazil

An agriculture-intensive country should be aware of natural toxins, including both mycotoxins and cyanotoxins, which are closely associated with the quality of raw materials, for food safety and industry. The major production chains – corn, wheat, beef, and broiler chicken – are the top components of agribusiness, and they should be tracked by reliable and practical tools. The corn chain is of particular concern in food production; intensive controls, multi-year mycotoxin monitoring, and improved harmless/sustainable management methods for uninterrupted farming in the tropic-subtropics are needed to achieve a long-lasting trend. The rapid control of natural toxins (mycotoxin and cyanotoxin) has focused on immunochemical methods developed with highly specific monoclonal antibodies (mAb) matched with chromatographic methods. In parallel, the promising widespread application of non-destructive analytical methods based on NIR (Near Infrared Reflectance) spectroscopy, computer vision and hyperspectral imaging coupled with multivariate analyses have been introduced as an alternative for the prediction of quality and compositional parameters. Rapid quality control and product traceability are discussed, as well as accurate monitoring, which is essential for potentially launching an innovative system for food production in Brazil

Studies on Inflammation-Inducing Factor of Toxin in the Cancer Tissue Part 1. Experimental study on inflammation-inducing factor contained in the fresh cancer tissue

Infiltration of leucocytes can be frequently found in cancer tissues, but it is not clear whether it is due to infection, by-products of the disintegration accompanying tissue necrosis by the proliferative infiltration of cancer, or toxin from cancer cells. With the purpose to clarify this point the author injected an aseptic extract prepared from cancer tissue under the skin of mice, and by making serial slice specimens and staining these with hematoxilineosin, investigated the manners of exudation of leucocytes. In the case of the extract of gastric cancer subcutaneously injected in mice a greater number of leucocytes are exudated far earlier than in the case of the extract of normal stomach tissue. Even when extracts of other cancer tissues including breast cancer tissue are similarly injected, a maked exudation of leucocytes can be recognized, suggesting that there is some inflammation-inducing factor in cancer tissue

Studies on Inflammation-Inducing Factor of Toxin in the Cancer Tissue Part 3. Experiment on leucocyte exudation with the extension specimens of the subcutaneous tissues obtained after the injection of the inflammation-inducing substance contained in cancer tissues

By observing tissue extension specimens prepared from the rabbits previously given subcutaneous injection of extracts of various cancer tissues for 5, 10, 20, 30, and 40 minutes, the author studied the exudation of leucocytes, and obtained the following results: The earliest exudation of leucocytes observable, namely, five minutes afterwards, is in the case of the cancer-tissue extracts obtained by treating with pyridine and acetone. The findings after the injection of these substances are a more marked hyperemia and dilation of blood vessels than in other cases. Moreover, despite a relatively small increase of leucocytes in blood vessls the exudation of leucocytes can be recognized. As for the exudation picture after 30 minutes, it is marked in the cancer tissue extracts, the euglobulin fraction of the cancer-tissue extracts, and heated cancer-tissue extracts, followed by the extracts of the cancer tissues treated with trichlor acetic acid and tannic acid

Studies on Inflammation-Inducing Factor of Toxin in the Cancer Tissue Part 2. Experimental study on leucocyte infiltration by injecting various substances extracted from cancer tissues

After injecting various substances extracted from cancer tissues under the skin of mice and preparing serial slice specimms stained with hematoxilin and eosin, the author studied the exudation of leucocytes, and obtained the following results: 1. After fractionating proteins in various extracts of cancer tissues with (NH4)2SO4 and injecting each fraction under the skin of test mice, it has been found that the inflammationinducing factor is contained abundantly in the euglobulin fraction. 2. Even when the extracts of cancer tissues, devoid of proteins after the treatment with trichlor acetic acid or tannic acid, are injected similarly, a marked infiltration of leucocytes can be recognized. 3. When these extracts are injected in the similar way even after heating 30 minutes at 60 C, the exudation of leucocytes can be observed markedly. 4. Substance extracted from cancer tissues by the same treatment as employed in extracting Menkin's leukotaxin demonstrates to contain a factor that induces a marked exudation of leucocytes
