With a reduced set of 300 neurons and a fully sequenced genome, the multicellular nematodeCaenorhabditis eleganshas recently gained increasing interest as a model organism for neurobiological studies. One particular area of interest is related to worm locomotion and the investigation of the correlation between individual genes, neurons, muscle arms and the motion pattern of the nematodes. To characterize motion patterns of movingC. eleganswe have previously demonstrated an automated force measurement setup using microfabricated polydimethylsiloxane (PDMS) pillars and image processing. In this paper we introduce an integrated microfluidic device for worm sorting and force measurement. The device allows for high-throughput measurements by combining sorting functions on-chip with the existing force pattern measurement system. A horizontal sorting channel and branching vertical pillar array channels are utilized for worm sorting. Using the former, the nematodes can be flow-directed into arrays of 40 µm and 60 µm diameter pillars based on worm size and type. This improves animal survival and increases the relevance of the force measurement by allowing one to match the amplitude of the worm movement to the pillar spacing. The PDMS based device consists of three layers: a fluidic layer with pillars for force measurement at the bottom, a gas layer on top and a thin PDMS layer sandwiched between them. By applying pressure to the gas layer, the membrane in the middle will be deflected thus restricting the worms’ movement in the fluidic channel.

Abstract. At present, the manual grading of soybean seeds is both time consuming and laborious, and detecting the full-surface information of soybean seeds using an existing automatic sorting machine is difficult. To solve this problem, an on-line omnidirectional inspection and sorting system for soybean seeds was developed using embedded image processing technology. According to the principles employed by the system, the surface friction properties and full-surface information such as the shape, texture and color of soybean seeds were adopted in the study. Soybean seeds were inspected and sorted using their full surface information in combination with the embedded image processing technology. Split, worm-eaten, gray-spotted, slightly cracked, moldy and normal soybeans were used to test the system. According to the test results, the optimum design parameters of the preliminary sorting device based on the friction properties were a tilting angle of 12° and a linear velocity of 0.4 m/s. Furthermore, the optimum design parameters of the directional integrated device were a tilting angle of 19° and a linear velocity of 0.45 m/s. The sorting speed was 400 soybeans per minute with 8-channel parallel transmission. The average sorting accuracies were 99.4% for split soybeans, 98.5% for worm-eaten soybeans, 98.5% for gray-spotted soybeans, 97.7% for slightly cracked soybeans, 98.6% for moldy soybeans, and 98.9% for normal soybeans. The overall results suggest that the system can potentially meet the needs of the rapid inspection and automatic sorting of soybean seeds and provide references for research on the alternating rotational motion of granules and on-line collection of full-surface information.

Full textAbstract:
The Caenorhabditis elegans (C. elegans) is an ideal model organism for studying human diseases and genetics due to its transparency and suitability for optical imaging. However, manually sorting a large population of C. elegans for experiments is tedious and inefficient. The microfluidic-assisted C. elegans sorting chip is considered a promising platform to address this issue due to its automation and ease of operation. Nevertheless, automated C. elegans sorting with multiple parameters requires efficient identification technology due to the different research demands for worm phenotypes. To improve the efficiency and accuracy of multi-parameter sorting, we developed a deep learning model using You Only Look Once (YOLO)v7 to detect and recognize C. elegans automatically. We used a dataset of 3931 annotated worms in microfluidic chips from various studies. Our model showed higher precision in automated C. elegans identification than YOLOv5 and Faster R-CNN, achieving a mean average precision (mAP) at a 0.5 intersection over a union (mAP@0.5) threshold of 99.56%. Additionally, our model demonstrated good generalization ability, achieving an mAP@0.5 of 94.21% on an external validation set. Our model can efficiently and accurately identify and calculate multiple phenotypes of worms, including size, movement speed, and fluorescence. The multi-parameter identification model can improve sorting efficiency and potentially promote the development of automated and integrated microfluidic platforms.

Waste management is one of the efforts to reduce the impact of environmental damage. The existence of counseling or socialization and training on household waste management in the community of Puspamukti Village, Cigalontang District, Tasikmalaya Regency is expected to understand the importance of household waste management in an environmentally friendly way, namely by sorting organic and inorganic waste and applying the 3R principle (reuse, reduce and recycle). In addition, the community received training in worm cultivation using the utilization of cultivation media derived from organic waste and worm feed nutrition from organic waste as well as making valuable products.

Full textAbstract:
Morphologically similar species, that is cryptic species, may be similar or quasi-similar owing to the deceleration of morphological evolution and stasis. While the factors underlying the deceleration of morphological evolution or stasis in cryptic species remain unknown, decades of research in the field of paleontology on punctuated equilibrium have originated clear hypotheses. Species are expected to remain morphologically identical in scenarios of shared genetic variation, such as hybridization and incomplete lineage sorting, or in scenarios where bottlenecks reduce genetic variation and constrain the evolution of morphology. Here, focusing on three morphologically similar Stygocapitella species, we employ a whole-genome amplification method (WGA) coupled with double-digestion restriction-site associated DNA sequencing (ddRAD) to reconstruct the evolutionary history of the species complex. We explore population structure, use population-level statistics to determine the degree of connectivity between populations and species, and determine the most likely demographic scenarios which generally reject for recent hybridization. We find that the combination of WGA and ddRAD allowed us to obtain genomic-level data from microscopic eukaryotes (∼1 millimetre) opening up opportunities for those working with population genomics and phylogenomics in such taxa. The three species share genetic variance, likely from incomplete lineage sorting and ancient admixture. We speculate that the degree of shared variation might underlie morphological similarity in the Atlantic species complex.

Full textAbstract:
The aim of this study is to examine if and how the diagnosis of ADHD is important for the social practice delimitation to obtain an understanding of how the sorting and categorization of clients affects the distribution of resources. In a qualitative approach, the study is based on eight semi-structured interviews in five different social practices. Young adults diagnosed with ADHD who need society's help and support, constituted our focus in the study. The selection is based on gaining an understanding of how the client process proceeds. The interviews were supplemented with documents, such as legal and internal methodological support. The empirical results relate to Hasenfeld´s discussion on "raw material" and "transforming process", Lindqvist´s "organizational fields", Johansson's "freedom of action" and Stone´s “dilemma of distribution". The results indicate that the diagnosis of ADHD represents the basis for the target group, young adults, to gain entry into the community social practices in order to obtain access to resources. The results also show that several factors determine the design of interventions: the needs of the individual and the ability to express their needs, the relationship between the professional and the individual, but also the professional´s freedom of action. Furthermore, the results show that the diagnosis of ADHD affects the possibility of collaboration between organizations.

Full textAbstract:
A central concern of generative grammar is the relationship between hierarchy and word order, traditionally understood as two dimensions of a single syntactic representation. A related concern is directionality in the grammar. Traditional approaches posit process-neutral grammars, embodying knowledge of language, put to use with infinite facility both for production and comprehension. This has crystallized in the view of Merge as the central property of syntax, perhaps its only novel feature. A growing number of approaches explore grammars with different directionalities, often with more direct connections to performance mechanisms. This paper describes a novel model of universal grammar as a one-directional, universal parser. Mismatch between word order and interpretation order is pervasive in comprehension; in the present model, word order is language-particular and interpretation order (i.e., hierarchy) is universal. These orders are not two dimensions of a unified abstract object (e.g., precedence and dominance in a single tree); rather, both are temporal sequences, and UG is an invariant real-time procedure (based on Knuth's stack-sorting algorithm) transforming word order into hierarchical order. This shift in perspective has several desirable consequences. It collapses linearization, displacement, and composition into a single performance process. The architecture provides a novel source of brackets (labeled unambiguously and without search), which are understood not as part-whole constituency relations, but as storage and retrieval routines in parsing. It also explains why neutral word order within single syntactic cycles avoids 213-like permutations. The model identifies cycles as extended projections of lexical heads, grounding the notion of phase. This is achieved with a universal processor, dispensing with parameters. The empirical focus is word order in noun phrases. This domain provides some of the clearest evidence for 213-avoidance as a cross-linguistic word order generalization. Importantly, recursive phrase structure "bottoms out" in noun phrases, which are typically a single cycle (though further cycles may be embedded, e.g., relative clauses). By contrast, a simple transitive clause plausibly involves two cycles (vP and CP), embedding further nominal cycles. In the present theory, recursion is fundamentally distinct from structure-building within a single cycle, and different word order restrictions might emerge in larger domains like clauses.

Full textAbstract:
O presente trabalho teve como objetivo realizar estudos para entender a percepção de consumidores em relação a salsichas com diferentes atributos de saudabilidade. Foram conduzidos três estudos e diferentes metodologias foram empregadas para explorar a atitude do consumidor. No primeiro estudo, a percepção dos consumidores foi avaliada através das técnicas de associação de palavras, aceitação de cada conceito (salsicha tradicional, com antioxidantes naturais, com redução de sódio, com redução de gordura, fonte de fibra alimentar e com ômega 3), grau de familiaridade com cada atributo de saudabilidade e resposta emocional. Para a salsicha tradicional, as categorias mais relevantes para os consumidores foram: modo de consumo, sabor agradável, não saudável, aparência (cor), gordura/caloria e pressão alta, já o grupo formado pelas salsichas com ômega 3, antioxidantes naturais, com redução de gordura e com redução de sódio se caracterizou principalmente pela percepção de saudabilidade. Para o segundo estudo, a relação entre a preocupação de consumidores com sua saúde e sua percepção sobre salsichas com adição de ingredientes funcionais (fibra alimentar e ômega 3) foi avaliada através do teste de completamento e da técnica de lista de compras. Não foram encontradas diferenças significativas entre os clusters (consciência em relação à saúde) para as razões apontadas pelos consumidores que incentivam (sabor agradável, praticidade, preço acessível e modo de consumo) e limitam (prejudicial à saúde, não saudável, ricas em sódio e gordura e artificial) a compra de salsichas. Os resultados do segundo estudo, ainda demonstraram que a adição de fibra alimentar e ômega 3 em salsicha gerou associações predominantemente positivas independente do nível de consciência em relação à saúde dos consumidores. Em relação ao terceiro estudo, na aplicação da técnica sorting task, termos como falta de conhecimento, natural, problemas de sabor e não atrativo caracterizaram o grupo formado pelas salsichas sem adição de fosfato e nitrito. Já as salsichas com antioxidantes naturais, fonte de fibra alimentar e com ômega 3 foram associadas a melhor qualidade nutricional e impacto positivo na saúde/organismo. Neste mesmo estudo, a técnica hard laddering revelou que os principais motivos que justificam as escolhas das salsichas com redução de sódio, com redução de gordura, com ômega 3, com antioxidantes naturais e fibra alimentar são preocupação com a saúde e vida longa. Os resultados obtidos nos três estudos demonstraram que os consumidores apresentam percepções distintas em relação aos diferentes tipos de salsicha (conceitos) avaliados, sugerindo que a indústria da carne deve considerar as particularidades identificadas ao desenvolver salsichas mais saudáveis e anunciar seus atributos.<br>The present paper aimed to perform studies to understand the consumers\' perception regarding frankfurter sausages with different healthiness attributes. Three studies were carried out and different methods were applied to explore the consumer\'s attitude. In the first study the consumers\' perception was evaluated through the technique of word association, acceptance of each concept (traditional frankfurter, with natural antioxidants, with reduced sodium, with reduced fat, as a source of dietary fibre, and with omega 3), level of familiarity with each attribute and emotional response. For the traditional frankfurter the most relevant categories for the consumers were: consumption mode, good flavour, unhealthy, appearance (colour), fat/calorie and high blood pressure, whereas the group formed by the frankfurters with omega 3, natural antioxidants, with reduced fat and reduced sodium was characterized especially by healthiness perception. For the second study the connection between the concern of consumer\'s with their health and their perception on frankfurters with the addition of functional ingredients (dietary fibre and omega 3) was evaluated through a completion test and the shopping list technique. No significant differences were found between the clusters (concern with health) for the reasons pointed out by the consumers that encourage (good flavour, convenience, price/cheap, and consumption mode) and restrict (harmful to health, unhealthy, rich in sodium and fat, and artificial) purchasing frankfurters. The results of the second study also demonstrated that adding dietary fibre and omega 3 in frankfurters provided predominantly positive associations regardless of consumers\' concerns with health. Regarding the third study, lack of knowledge, natural, flavour defects and not appealing characterized the group formed by frankfurters with no phosphate added and no nitrite added through the sorting task technique. The frankfurters with natural antioxidant, as a source of dietary fibre and with omega 3 were associated to a better nutritional quality and positive impact on health/organism. The hard laddering technique revealed that the main reasons that justify the choices for the frankfurters with reduced sodium, reduced fat, with omega 3, with natural antioxidants and dietary fibre are concerns with health and longevity. The results obtained through the three studies showed that the consumers present distinctive perceptions concerning different types of evaluated frankfurters (concepts), suggesting that the meat industry should consider the particularities identified to develop healthier sausages and advertise their attributes.

Full textAbstract:
Le travail de sortie d’un métal est une propriété fondamentale en physico-chimie des matériaux. C’est l’énergie nécessaire pour extraire un électron depuis le niveau de Fermi vers le niveau du vide. Il est connu que cette grandeur dépend de la nature du métal, mais aussi que d’autres paramètres ont une influence notable. Ainsi ce travail de thèse montre comment le travail de sortie peut être modulé par une couche de molécules auto assemblées sur la surface métallique, et comment il évolue quand le matériau est sous forme de nanoparticules. La présente étude se concentre sur des nanoparticules d’or (AuNPs) de diamètres compris entre 10 et 60 nm, et étudie les effets de fonctionnalisation par quatre molécules : l’hexanedithiol (HDT), l’aminooctanethiol (AOT), l’acide mercaptohexadecanoïque (MDHA) et le dodécanethiol (DDT). Après une étude détaillée des morphologies des surfaces planes d’or fonctionnalisées par microscopie à force atomique (AFM), des mesures de travail de sortie sur ces surfaces sont effectuées par microscopie à sonde de Kelvin (KPFM). En comparant ces résultats à des mesures de photoémission (UPS), l’effet de chaque fonctionnalisation est mis en évidence. Par exemple, le travail de sortie d’une surface fonctionnalisée par MHDA diminue de -0.30 eV par rapport à une surface d’or non fonctionnalisée. Ces résultats montrent aussi l’effet sur le travail de sortie du temps de contact avec l’atmosphère ambiante. Ensuite, nous abordons le cas des AuNPs, synthétisées par voie colloïdale, puis post-fonctionnalisées par AOT ou par MDHA. La fonctionnalisation des AuNPs est suivie par des mesures optiques basées sur la mesure du pic d’absorption (plasmon) des AuNPs dans le visible. Après fonctionnalisation, leur travail de sortie est mesuré par KPFM. Ces mesures mettent en évidence deux phénomènes : la modification du travail de sortie par la fonctionnalisation, ainsi qu’une variation en fonction de la taille de l’AuNP. Dans le but de comprendre précisément cet effet de taille, nos systèmes ont été modélisés par une approche DFT (density functional theory), et les calculs de travaux de sortie ont été confrontés aux mesures expérimentales. Ces calculs sont en très bon accord avec les résultats expérimentaux, notamment sur l’évolution du travail de sortie en fonction de la taille des particules, d’environ 1 meV.nm 1<br>The work function of a metal is a fundamental property in materials study, defined as the energy required to extract an electron from the Fermi level to the vacuum level. It is known that this magnitude depends on the nature of the metal, but also that other parameters have a significant influence. Thus this thesis work shows how the work function can be modulated by a layer of self-assembled molecules on the metal surface, and how it evolves when the material is in the form of nanoparticles. The present study focuses on gold nanoparticles (AuNPs) of diameters between 10 and 60 nm and studies the effects of functionalization by four molecules: hexanedithiol (HDT), aminooctanethiol (AOT), mercaptohexadecanoic acid (MDHA) and dodecanethiol (DDT). After a detailed study of the functionalized plane gold surfaces morphologies by atomic force microscopy (AFM), measurements of work function on these surfaces are carried out by Kelvin probe force microscopy (KPFM). By comparing these results with photoemission measurements (UPS), the effect of each functionalization is highlighted. For example, the work function of a MHDA functionalized gold surface decreases by -0.30 eV compared to a non-functionalized gold surface. These results also show the effect of the contact time with the ambient atmosphere on the work function. Then we discuss the case of colloidal-synthesized AuNPs, then post-functionalized by AOT or MDHA. The functionalization of AuNPs is followed by optical measurements. It is based on the measurement of the absorption peak (plasmon) of AuNPs in the visible. After AuNPs functionalization, their work function is measured by KPFM. These measurements highlight two phenomena: the modification of the work function by the functionalization, as well as a variation according to the size of the particle. In order to understand precisely this size effect, our systems were modeled by a DFT approach (density functional theory), and the work function calculations were compared with the experimental measurements. These calculations are in very good agreement with the experimental results, in particular on the evolution of the work function according to the size of the particles, of approximately -1 meV.nm-1

Full textAbstract:
Nos últimos anos, importantes riscos ocupacionais em centrais de triagem de materiais recicláveis têm sido apontados na literatura nacional e internacional. Grande parte desses riscos é creditada à baixa qualidade da segregação realizada pela população, resultando no encaminhamento de resíduos sujos para a coleta seletiva de recicláveis. Danos à saúde e segurança dos trabalhadores que manipulam esses materiais podem surgir se as condições estruturais, tecnologias empregadas, organização do trabalho e medidas de prevenção necessárias não forem adequadamente gerenciadas. Objetivos: identificar os fatores de risco ocupacional em duas centrais de triagem do município de São Paulo; quantificar lesões e doenças ocorridas antes e durante o período do estudo; correlacionar os fatores de risco com as lesões e doenças identificadas e recomendar ações para minimizar os danos à saúde desses trabalhadores. Metodologia: trata-se de estudo de caso múltiplo, exploratório, com abordagem quanti-qualitativa. Iniciado com revisão sistematizada da literatura, focou a saúde dos catadores de recicláveis, contemplando duas bases de dados bibliográficas em ciências da saúde: PubMed e LILACS. Duas centrais de triagem foram selecionadas para o estudo após levantamento preliminar da situação em cinco cooperativas participantes do Programa de Coleta Seletiva do Município de São Paulo. O estudo qualitativo incorporou dados obtidos por meio de observações e medições in loco, revisão de documentos e grupos focais com catadores. Os dados quantitativos foram levantados mediante aplicação de questionário e avaliação clínica individualizada dos 83 participantes de ambas cooperativas. As informações obtidas foram integradas, analisadas e comparadas com outros estudos sobre centrais de triagem de recicláveis brasileiras e estrangeiras. Resultados: poucas melhorias nas condições de trabalho foram conquistadas pelos catadores cooperativados que atuam em centrais de triagem de recicláveis, se comparados aos catadores de lixões e das ruas. Os níveis de produtividade são baixos, assim como a consequente remuneração. Não possuem capacidade técnica para sustentar o empreendimento tanto no âmbito gerencial, organizacional ou operacional. Medidas para a promoção da saúde, prevenção de acidentes e doenças são pontuais e mínimas. Diversos fatores de risco (físico, químico, biológico, mecânico, de acidentes, ergonômico e psicossocial) foram identificados e correlacionados com doenças e acidentes revelados pelos participantes. As manifestações clínicas mais frequentes foram: dores musculoesqueléticas (77 por cento ), lesões no corpo (48 por cento ) e problemas respiratórios (43 por cento ). Cortes ou perfurações foram relatados por 69 por cento dos participantes. Conclusão: algumas atitudes inéditas e práticas operacionais arriscadas foram reveladas e, seguramente, demandam intervenções indispensáveis e imediatas. Os desfechos deste estudo são importantes para suscitar reflexões, ampliar discussões e poderão contribuir para a tomada de decisão em diversas esferas de gestão (saúde, previdência, trabalho e ambiente), assim como servir aos interesses e necessidades dos trabalhadores e da sociedade.<br>In recent years, the presence of noticeable occupational hazards in recycling sorting facilities has been pointed out in national and international literature. Most of these risks are credited to the poor quality of the separation carried out by the population, resulting in the sending of dirty and hazardous waste for the selective collection of recyclables. Damage to the health and safety of workers who handle such materials may arise if the structural conditions, technologies, work\'s organizations and preventive measures adopted are not properly managed. Objectives: identify the occupational risk factors in two sorting facilities in the city of São Paulo; quantify injuries and diseases which had occurred before and during the study period; correlate risk factors with the injuries and diseases identified and recommend actions to minimize the damages to these workers\' health. Methodology: it is a multiple case study, exploratory, with quantitative-qualitative approach. It was initiated with a systematized review of the literature, focused on the health of recyclable waste pickers, covering two bibliographic databases in health science: PubMed and LILACS. Two sorting facilities were selected for this study after a preliminary survey of the situation in five cooperatives associated with the Selective Collection Program of the Municipality of São Paulo. The qualitative study incorporated data obtained through in situ observations and measurements, review of documents and focus groups with waste pickers. The quantitative data was collected through the application of a questionnaire and individualized clinical evaluation of the 83 participants of both cooperatives. Data obtained was integrated, analyzed and compared with other studies in Brazilian and foreign sorting facilities. Results: few improvements in working conditions were achieved by cooperative waste pickers working in recyclable sorting facilities compared to those acting in open dumps or streets. The level of productivity is low, as well as the consequent wages. They do not have the necessary background to give support in management, organization, or operations. Measures to promote health, prevention of accidents or diseases are punctual and minimal. Several risk factors (physical, chemical, biological, mechanical, accidental, ergonomic and psychosocial) were identified and correlated with diseases and accidents revealed by participants. The most frequent clinical manifestations were: musculoskeletal pain (77 per cent ), body injuries (48 per cent ) and respiratory problems (43 per cent ). Cuts or perforations were reported by 69 per cent of the participants. Conclusion: some previously unknown and unexpected attitudes and risky operational practices have been revealed and certainly require immediate and indispensable interventions. The outcomes of this study are important in order to stimulate reflection, broaden discussions and contribute to decision-making in various spheres of management (health, welfare, work and environment), as well as serving to the interests and needs of workers and society.

Full textAbstract:
La compréhension des propriétés électriques de nano-objets est essentielle pour le développement s des nanotechnologies. La microscopie à force Kelvin (KFM) est une des techniques les plus utiles pour cartographier simultanément la topographie et la différence de potentiel de contact (CPD) à l'échelle nanométrique. Après 20 ans de développement, la KFM est principalement utilisé dans des conditions normales de pression et de température, permettant d'effectuer, de manière simple, de multiples analyses comparatives. Toutefois, sous ultra-vide (UHV), comme la surface est contrôlée et que la sensibilité est meilleure, des mesures plus précises et plus fiables sont réalisables. Dans la première partie, la mesure KFM sous atmosphère ambiante est améliorée en développant la technique simple-passage à la fois en modulation de fréquence (FM) et en modulation d'amplitude (AM). Une électronique externe Nanonis a été adaptée sur les AFMs commerciaux (Dimension 3100 et MultiMode, Bruker). Une étude comparative avec le mode Lift a été réalisée sur des couches de graphène épitaxié sur échantillon de SiC. L'effet de la distance pointe-échantillon sur le contraste et la résolution est décrit ainsi que l'influence des paramètres expérimentaux. Une amélioration significative du contraste et de la résolution est clairement observée sur les résultats obtenus par la technique simple passage en modulation de fréquence, indépendamment de la distance pointe-échantillon. Dans une deuxième partie, la technique KFM est développée sous vide secondaire. Le travail instrumental est réalisé sur un AFM EnviroScope de chez Bruker, qui a été équipé d'une électronique externe Nanonis, permettant de mesurer simultanément la topographie en mode non-contact et la CPD en modulation d'amplitude ou de fréquence. Les résultats montrent que la CPD mesurée est comparable à celle obtenue avec une mesure sous ultravide. Enfin, après avoir posé les bases à la fois expérimentale et théorique de la KFM, cette technique est utilisée pour caractériser les hétérostructures CdTe/CdS en films minces utilisés pour les applications de cellules solaires. Un protocole de préparation d'échantillon sur la tranche a été spécialement développé. L'hétérojonction CdTe/CdS est étudiée sous polarisation à la fois dans l'obscurité et sous éclairement. L'influence de l'épaisseur de la couche de CdS est également étudiée pour comprendre son effet dramatique sur le rendement des cellules solaires.

Furthermore, using matched employer-employee panel data covering the complete Swedish labor market, this essay decomposes wage catch-up into relative wage growth within and between workplaces and occupations. The results show that failing to control for selection into employment is likely to underestimate relative wage growth of immigrants, as early entrants in the labor market differ from later entrants along unobservable dimensions. Even after 30 years in the country, the group of non-western immigrants still earns substantially lower wages than natives. Wages catch up mainly within workplaces and occupations, suggesting that improved signals of productivity, rather than improved knowledge of job options, are of importance for the wage growth of non-western immigrants. Essay 2: Earlier research has shown that immigrant- and minority entrepreneurs have difficulties accessing capital through the formal financial markets. This essay studies what role immigrant employees within the local bank sector have for the probability of immigrants to run their own businesses. I use linked employer-employee data covering the whole Swedish labor market for the years 1987 to 2003 and utilize a nationwide refugee dispersal policy to get exogenous variation in the exposure to co-ethnic bank employees. Results suggest that there is a positive relation between co-ethnic bank employees and the probability of being self-employed. This effect is most pronounced for immigrants who arrived with low education, for males and for those residing in metropolitan regions. The effects are substantial and robust to a wide set of controls for labor market characteristics of the ethnic group at the local level. These results provide evidence of an ethnic component in the formal credit markets. Essay 3 (with Oskar Nordström Skans): This essay investigates the impact of a collective agreement stipulating a one shot increase in establishment-specific wage levels in a public-sector setting where wages otherwise are set according to individualized wage bargaining. The agreement stipulated that wages should increase in proportion to the number of low-paid females within each establishment. We find that actual wages among incumbents responded to the share of females with a wage below the stipulated threshold, conditional on the separate effects of the share of low wage earners, and the share of females. We find clear evidence of path-dependence in wages, covered workers remained on higher wage levels 4 years after the agreement took effect. The increase in wages resulted in a reduced probability of exit among young workers with relatively good grades and a lower frequency of new hires at the establishment level.

Centrada en l'àmbit de la formació universitària de competències, aquesta tesi doctoral estudia el nivell de competències dels estudiants de l'últim curs de Psicologia de les Organitzacions de la Facultat de Psicologia, Ciències de l'Educació i de l'Esport Blanquerna, de la Universitat Ramon Llull. El focus de la investigació és doble: Per una banda, es comparen les competències dels subjectes al final de la seva carrera amb les competències del perfil d'una categoria professional concreta, la del tècnic en Recursos Humans, que ha estat definit i validat per experts en actiu d'aquesta àrea de activitat professional. I per altra banda, es valora el grau de desenvolupament de les competències d'un grup de subjectes que ha rebut una formació específica al llarg de tot el curs acadèmic 2003-2004 en un espai formatiu concret, el seminari d'aprenentatge cooperatiu en el format que és propi de la metodologia Blanquerna. Des d'aquesta perspectiva professional i educativa a la vegada, la recerca troba els seus fonaments teòrics en tres eixos que configuren el marc conceptual: les competències com a factor de qualitat incorporat a diversos models de gestió, el disseny dels curricula de formació universitària davant els reptes plantejats per l'Espai Europeu d'Educació Superior i les exigències competencials de l'àrea dels Recursos Humans, on els nou titulats de Psicologia de les Organitzacions solen trobar una primera via d'entrada a la professió. La metodologia del treball utilitza l'assessment center com a mètode integral d'avaluació de les competències, per tal d'obtenir també una aportació doble: els instruments que serviran als avaluadors externs per mesurar el nivell competencial del grup focal i del grup control tant al començament i com al final del curs i les activitats formatives adreçades a desenvolupar les competències del perfil estudiat. Mitjançant el tractament estadístic de les dades obtingudes en les diferents fases del procés és possible establir els nivells comparatius entre el perfil acadèmic de sortida i el perfil professional d'entrada, així com el grau de desenvolupament de les competències del grup focal que rep la formació basada en competències. D'acord amb les hipòtesis plantejades, els resultats confirmen que existeixen diferències significatives entre el perfil de formació i el perfil professional i que les accions formatives implementades al seminari són efectives per desenvolupar, també significativament, algunes de les competències que configuren el perfil.<br>Centrada en el ámbito de la formación universitaria de competencias, esta tesis doctoral estudia el nivel de competencias de los estudiantes del último curso de Psicología de las Organizaciones de la Facultat de Psicologia, Ciències de l'Educació i de l'Esport Blanquerna, de la Universitat Ramon Llull.

The investigation has a double focus: On the one hand, the competences of the individual at the end of his career are compared with the competences of a concrete professional category profile, that of the Human Resources technician, which has been defined and validated by experts in this professional field. At the other hand, we have evaluated the development level of a group of individuals who have received a specific training throughout the 2003-2004 academic course in a concrete training environment, the seminary, a methodologic format in Blanquerna cooperative learning. From this professional and educational view, the investigation finds his theoretical foundation in three points that configure the conceptual framework: the competences as a quality factor in many management models, the design of the university training curricula faced with the challenges that are posed by the European Space of High Education and the competence requirements in the Human Resources field, where the Work and Organizational Psychologists usually find their first job. The Assesment Center is used as an integral method for evaluating competences, with the goal of obtaining also a double contribution: the instruments that will serve to the external evaluators for measuring the competence level of the focal and control groups, both at the start and at the end of the mentioned course, and the training activities directed to develop the competences of the studied group. In turn, the statistic treatment of the data obtained in all the different phases of the process, allows us to establish the comparative levels between the the outcoming academic profile and the incoming professional profile, just as the development grade of the focal group that received the competence based training. In keeping with the suggested hypothesis, the results confirm that significant differences exist between the academic profile and the professional profile, and also that the training actions implemented in the seminary are useful to significantly develop some of the competences of the studied profile.

Cette thèse porte sur l’élaboration et la caractérisation électrique et physico-chimique des grilles métalliques des dispositifs FDSOI MOSFET 14 nm à base d’oxyde high-K fabriqués chez STMicroelectronics. Ces grilles métalliques sont composées de couches de TiN, lanthane et aluminium, déposées par pulvérisation cathodique RF. Des structures de test et un schéma d’intégration simplifié permettant l’analyse capacitive ont été mis en place pour caractériser la modulation du travail de sortie effectif des grilles métalliques en TiN avec l’incorporation d'additifs tels que le lanthane ou l’aluminium. Ces additifs ont été incorporés suivant une approche de grille sacrificielle. Par ailleurs, une méthodologie inédite basée sur la fluorescence X a été proposée et validée pour la caractérisation précise en ligne de la diffusion des additifs. Cette méthodologie permet de prouver que la dose effective de l’espèce incorporée après recuit de diffusion peut être modélisée en fonction de l’épaisseur du TiN piédestal dans la grille sacrificielle ainsi que de la température de recuit. De plus, la variation de l’épaisseur de l’oxyde interfaciel sur une seule plaquette (oxyde biseau) autorise l’identification de l’origine physique de la modulation du travail de sortie effectif, qui s’explique par un dipôle qui évolue avec la dose effective de l’espèce incorporée. En conséquence, un modèle de la diffusion des dopants de grille dans l’oxyde high-K et de leur impact sur le travail de sortie effectif des grilles métalliques a été proposé afin de moduler avec précision la tension de seuil (VTH) des dispositifs FDSOI 14 nm. En outre, l’impact de l’oxyde high-K à la fois sur la diffusion des additifs et sur la modulation du travail de sortie effectif a été mis en évidence. Enfin, un procédé innovant de dépôt métallique, permettant la modification de la microstructure du TiN, a été développé afin d’améliorer davantage la variabilité locale du VTH des dispositifs FDSOI<br>This Ph.D. thesis is focused on the fabrication and electrical and physicochemical characterization of metal gates in 14 nm high-K based FDSOI MOSFET devices, manufactured at STMicroelectronics. These metal gates are composed of TiN, lanthanum and aluminum layers, deposited by RF sputtering. Test structures and a simplified integration scheme allowing C-V measurements, have been implemented in order to characterize the modulation of the effective work function of TiN metal gates with the incorporation of dopants such as lanthanum or aluminum. These additives are incorporated in a sacrificial gate-first approach. Furthermore, a new methodology based on X-ray fluorescence was proposed and validated for accurate in-line characterization of the diffusion of dopants. This methodology enables to prove that the effective dose of the species incorporated into dielectrics after diffusion annealing may be modeled as a function of the thickness of the pedestal TiN in the sacrificial gate and the annealing temperature. Moreover, the variation of the thickness of the interfacial oxide along the wafer (bevel oxide) authorizes the identification of the origin of the modulation of the effective work function, which is explained by a dipole that evolves with the effective dose of the incorporated dopant. Accordingly, a model of the diffusion of dopants into the gate dielectrics and their impact on the effective work function of metal gates has been proposed to precisely modulate the threshold voltage (VTH) of the 14 nm FDSOI devices. In addition, the influence of the high-K oxide on both the diffusion of dopants and the modulation of the effective work function was highlighted. Lastly, an innovative process for metal deposition, allowing the modification of the microstructure of TiN, was developed in order to further improve the local VTH variability in FDSOI devices

L'introduction du SiGe dans les pMOS (Bulk et FDSOI) exige un bon contrôle de la tension de seuil (VT). Ceci nécessite une extraction précise des paramètres électriques ainsi qu'une compréhension des effets électriques du Ge dans de tels dispositifs. Dans cette thèse, nous avons d'abord proposé des méthodes pour une identification précise des paramètres électriques du « gate stack »: VT, la tension de bande plate (VFB) et l'épaisseur équivalente d'oxyde (EOT). Ces méthodes ont été validées avec des simulations Poisson-Schrödinger (PS) et appliquées avec succès aux mesures. Dans un second temps, nous avons étudié les effets électriques du Ge sur les paramètres du « gate stack » des pMOS. La comparaison des caractérisations électriques (C-V) avec les simulations PS a montré un décalage supplémentaire du travail de sortie effectif qui croit avec le Ge. Des caractérisations STEM, EELS et SIMS ont prouvé que ce décalage est due à la présence de dipôles à l'interface SiGe/oxyde<br>Maintaining good threshold voltage (VT) centering is a paramount challenge for CMOS technology. The SiGe introduction in bulk and FDSOI pFETs requires VT control for such devices. To this end, we have to extract accurately electrical parameters and to understand Ge integration effects in SiGe based pFETs. In this thesis, first, we have proposed extraction methods to determine VT, flat band voltage (VFB) and equivalent oxide thickness (EOT) parameters in bulk and FDSOI transistors. The extraction methods have been validated via Poisson-Schrodinger (PS) simulations and successfully applied to measurements. Second, we have highlighted and explained electric effects of Ge on pMOS gate stack parameters. Electrical characterizations compared with PS simulations have evidenced an additional effective work function increase, induced by Ge, related to interfacial dipoles. STEM, EELS and SIMS characterizations have demonstrated that dipoles are located at SiGe/IL interface

Abstract In recent years, with the development of society, market competition has become increasingly fierce. Business in industries such as e-commerce and express delivery has exploded. The development of the logistics industry is also accelerating, and the large-scale manual assembly line work no longer meets our current needs. The demand for automation has become higher and higher. Therefore, it is especially important to design fully automatic material sorting devices according to different needs, in order to satisfy our requirements.

AbstractThis work addresses the use of a MO optimization algorithm to deal with the reliability optimization problem in order to determine the redundancy and reliability of each component in the system. Often, these problems are formulated as a single-objective problem with mixed variables (real-integer) and is subject to various design constraints. Classical solution approaches were limited to deal with these problems and most recent solution approaches are based on nature-inspired optimization algorithms which belong to artificial intelligence (AI). In the present paper, the problem is solved as a MO optimization problem through the Non-dominated Sorting Genetic Algorithm II (NSGA-II) to generate the set of optimal solutions, also called Pareto. The latter helps the decision-maker. The case studied consists of a pharmaceutical plant.

AbstractThis chapter takes a closer look at the character Sherlock Holmes in both Arthur Conan Doyle’s Sherlock Holmes stories and the BBC show Sherlock (2010–2017). Both versions of Sherlock Holmes capitalize on the affordances of visibility and comprehensiveness inherent in the form of the list. These affordances of the list allow the characters to make the mere reference to the bodies of knowledge they draw on stand in for the knowledge itself. Doyle’s detective uses the list-like paper technologies of sorting, selecting, and summarizing and the frequent mentioning of reference works to create the illusion that his deductions are based on a sound method. The BBC’s Sherlock makes use of the Internet in a similar list-based manner. Since visualization, simplification, and spatialization are central elements of this strategy of replacing tangible evidence with mere references, the chapter examines similarities between the cognitive processes at work when we read lists and maps—two forms that share these affordances.

Full textAbstract:
AbstractThe amount of unstructured scientific data in the form of documents, reports, papers, patents, and the like is exponentially increasing each year. Technological advances and their implementations emerge at a similarly fast pace, making for many disciplines a manual overview of interdisciplinary and relevant studies nearly impossible. Consequently, surveying large corpora of documents without any automation, i.e. information extraction systems, seems no longer feasible. Fortunately, most articles are now accessible through digital channels, enabling automatic information retrieval by large database systems. Popular examples of such systems are Google Scholar or Scopus. As they allow us to rapidly find relevant and high-quality citations and references to previous work, these systems are particularly valuable in academic writing. However, not all users are aware of the mechanisms underlying relevance sorting, which we will address in this chapter. For example, in addition to searching for specific terms, new tools facilitate the discovery of relevant studies by using synonyms as well as similar works/citations. The near future holds even better tools for the creation of surveys, such as automatic summary generation or automatic question-answering systems over large corpora. In this chapter, we will discuss the relevant technologies and systems and their use in the academic writing context.

Abstract In this work, we explore the use of artificial neural networks (ANN, net) in sorting and interpreting the impact of mechanical variables [such as applied stress intensity factor (Kmax), amplitude and frequency of loading (ΔK, ω)] and environmental parameters [e.g., the corrosion potential (ECP)] on fatigue crack growth in steels in high temperature aqueous systems. In doing so, we reviewed and collected fatigue crack growth rate (FCGR) data from the open literature, we constructed a suitable database (mainly from data obtained from the Argonne National Laboratory) for use (as inputs) with the Artificial Neural Network (ANN), we designed an ANN and trained it on the data base, and we used the ANN to extrapolate the range of input variables. We discuss the predictions of the ANN, and we compare and contrast our findings with known and expected trends.

Currently, the most advanced countries in terms of green thinking and production are Scandinavia, Switzerland, the Netherlands, Australia and New Zealand. The Baltic States also have adopted a joint Climate Declaration with a commitment to climate neutrality. The global production and consumption of plastics have doubled over the last two decades, yet only approximately 30% of plastic waste is recycled and reused, while the rest ends up in the environment. We all must play a role in protecting the environment at home, at work and in our free time. Sorting waste is the easiest way, yet it is not the only way. In the case of plastic tableware, it could also translate into new practices, habits and the reuse of tableware made of plastics containing no substances harmful to health, which could be used for buying food or drinks. In Latvia too, several companies offer discounts, e.g. if buying coffee and pouring it into one�s own thermal mug. One such plastic tableware manufacturer is Tupperware, which defines sustainability as a core value from production to product sale. The research aims to describe a system Tupperware has put in place to reduce waste and educate people to mitigate climate change. The research results revealed that cooperation was key to the system. Cooperation was important in obtaining information, procuring raw materials, selling products, and transferring knowledge into preservation practices.

The workers who are involved in the collection and sorting of waste are susceptible to a range of occupational hazards, such as musculoskeletal disorders, respiratory issues, physical harm. The aim of the study was to analyze ergonomic risks for waste sorting operators and garbage collectors, in one of the waste processing companies in Latvia and to develop preventive measures. The questionnaire and several ergonomic risk analysis methods were used in order to find out the opinion of workers about ergonomic strain and assess the ergonomics risks at the workplaces. Results show that waste sorting operators and garbage collectors are exposed to a range of ergonomic risks at work during work shifts. The ergonomic risk assessment methods used in the study revealed that both groups are exposed to a moderate workload with an overall risk level of III. This suggests that the occupations studied are subjected to overload at the work and preventive measures have been suggested.

Full textAbstract:
Cell sorting is an important technique for single-cell research. Especially, micro-chip cell sorting has recently attracted attention for its potential of high-speed manipulation efficiency [1,2]. Now, we have developed a new cell sorting system combining a femtosecond laser (fs-laser) with a microfluidic chip. When an intense fs-laser is focused into liquid, an explosive evaporation of the aqueous solutions at the laser focal point induces a jet flow, which is utilized as an external force for manipulation. Herein, we proposed to modify this jet flow by making a micro-structure. In this work, we studied on fluid dynamics at micro-structure in the chip channel, and applied this to our new sorting system.

Full textAbstract:
Radio-frequency identification (RFID) and mechatronic technology has been applied to a laundry sorting system which can potentially be used by rest homes in the future to reduce the labour intensity of care givers, to increase the efficiency of laundry sorting, and to reduce the chance of garments being lost. A laboratory laundry identifying and sorting conveyor belt has been built. Several different types of RFID labels/tags have been considered and tested. A type of small RFID laundry tag, suitable for the laundry sorting conditions of a rest home, has been selected. The laundry tags have undergone endurance testing under actual washing and drying conditions with typical commercial laundry chemical products used in rest homes. There was a major challenge using commercial RFID tags in the proposed intelligent laundry sorting system due limitations in their antenna and signal receiving systems. A strategy to coordinate the orientations of the tags, range of the antenna, and the amplification of signal receiving units has been investigated. Several antenna designs to improve the identification rate have been tested and analysed for the selected small laundry tags, since the tag-receiver system has to work beyond the recommended range. A programme for signal detection and processing has been produced. The programme has taken into consideration the speed of the conveyor belt, antenna receiving range and the time required to process signals. It works with satisfactory precision at a satisfactory speed. A sorting strategy for implementation after laundry garment identification has been investigated. This strategy considers aspects of simplicity, multifunction and compactness of mechanical structure. A virtual sorting system has been produced to test the principles of the sorting strategy and the antenna design. The results of these tests will help us to move to the next stage, the design of a prototype laundry sorting system.

This work presents continuous-flow particle sorting at low applied fields (30 V/cm) using electrodeless dielectrophoresis [2–7] in ridged polymeric microstructures. Particle manipulation and sorting is critical in analysis of cellular systems and subpopulations, water monitoring, soil analysis, and colloidal synthesis. This technique is developed with a view toward sorting of cellular systems, and offers advantages over other particle processing techniques in its ability to sort particles over small (~100 μm) spatial scales and rapid (&lt;1s) time scales while operating under the low electric fields required when using solutions of physiological salinity.

Objective: The objective of this research was to investigate the potential use of NMR for evaluating various internal quality factors of fruits and vegetables, leading to the eventual development of practical techniques that are useful for future development of NMR sensors. Summary: Investigation on NMR imaging, one-dimension NMR projection, and single-pulse free-induction-decay (FID) spectrum led to the development of high-speed NMR techniques for real-time sensing of internal quality of selected fruits. NMR imaging can be used for detecting internal defects and various quality factors such as bruises, dry regions, worm damage, stage of ripeness, tissue breakdown, and the presence of voids, seeds, sprouts, and pits. The one-dimension (1-D) image profile technique, in which the 1-D projection of the NMR signal of a selected slice of the intact fruit is recorded, is suitable for detecting tissue breakdown regions, presence of pits, and other defects in fruits. The oil and sugar content of fruits can be determined from the single-pulse FID spectrum measurement, in which a surface coil is used to acquire the FID spectrum and the ratio of the resonance peaks is used as the quality index. The latter two techniques are suitable for high-speed sorting of fruits. The most important accomplishment is the successful development of high-speed NMR techniques for determining internal quality of fruits while they are moving at speed up to 30 cm/s. This accomplishment is an important step toward the development of NMR techniques for on-line sorting of fruits and vegetables.

We provide a framework for setting congestion charges that reflect emission and congestion externalities and policy responses, such as vehicle ownership, driving, and residential sorting. Using Swedish administrative microdata, we identify these responses by exploiting a temporary exemption for alternative fuel vehicles and variation in individuals’ exposure to congestion charges. We find that commuters respond by adopting exempted alternative fuel vehicles, shifting trips away from fossil fuel toward alternative fuel vehicles, and changing where they live and work. We combine the estimated responses with the framework to recover an optimal congestion charge of €9.46 per crossing in Stockholm.

The objectives of this project were to develop nondestructive methods for detection of internal properties and firmness of fruits and vegetables. One method was based on a soft piezoelectric film transducer developed in the Technion, for analysis of fruit response to low-energy excitation. The second method was a dot-matrix piezoelectric transducer of North Carolina State University, developed for contact-pressure analysis of fruit during impact. Two research teams, one in Israel and the other in North Carolina, coordinated their research effort according to the specific objectives of the project, to develop and apply the two complementary methods for quality control of agricultural commodities. In Israel: An improved firmness testing system was developed and tested with tropical fruits. The new system included an instrumented fruit-bed of three flexible piezoelectric sensors and miniature electromagnetic hammers, which served as fruit support and low-energy excitation device, respectively. Resonant frequencies were detected for determination of firmness index. Two new acoustic parameters were developed for evaluation of fruit firmness and maturity: a dumping-ratio and a centeroid of the frequency response. Experiments were performed with avocado and mango fruits. The internal damping ratio, which may indicate fruit ripeness, increased monotonically with time, while resonant frequencies and firmness indices decreased with time. Fruit samples were tested daily by destructive penetration test. A fairy high correlation was found in tropical fruits between the penetration force and the new acoustic parameters; a lower correlation was found between this parameter and the conventional firmness index. Improved table-top firmness testing units, Firmalon, with data-logging system and on-line data analysis capacity have been built. The new device was used for the full-scale experiments in the next two years, ahead of the original program and BARD timetable. Close cooperation was initiated with local industry for development of both off-line and on-line sorting and quality control of more agricultural commodities. Firmalon units were produced and operated in major packaging houses in Israel, Belgium and Washington State, on mango and avocado, apples, pears, tomatoes, melons and some other fruits, to gain field experience with the new method. The accumulated experimental data from all these activities is still analyzed, to improve firmness sorting criteria and shelf-life predicting curves for the different fruits. The test program in commercial CA storage facilities in Washington State included seven apple varieties: Fuji, Braeburn, Gala, Granny Smith, Jonagold, Red Delicious, Golden Delicious, and D'Anjou pear variety. FI master-curves could be developed for the Braeburn, Gala, Granny Smith and Jonagold apples. These fruits showed a steady ripening process during the test period. Yet, more work should be conducted to reduce scattering of the data and to determine the confidence limits of the method. Nearly constant FI in Red Delicious and the fluctuations of FI in the Fuji apples should be re-examined. Three sets of experiment were performed with Flandria tomatoes. Despite the complex structure of the tomatoes, the acoustic method could be used for firmness evaluation and to follow the ripening evolution with time. Close agreement was achieved between the auction expert evaluation and that of the nondestructive acoustic test, where firmness index of 4.0 and more indicated grade-A tomatoes. More work is performed to refine the sorting algorithm and to develop a general ripening scale for automatic grading of tomatoes for the fresh fruit market. Galia melons were tested in Israel, in simulated export conditions. It was concluded that the Firmalon is capable of detecting the ripening of melons nondestructively, and sorted out the defective fruits from the export shipment. The cooperation with local industry resulted in development of automatic on-line prototype of the acoustic sensor, that may be incorporated with the export quality control system for melons. More interesting is the development of the remote firmness sensing method for sealed CA cool-rooms, where most of the full-year fruit yield in stored for off-season consumption. Hundreds of ripening monitor systems have been installed in major fruit storage facilities, and being evaluated now by the consumers. If successful, the new method may cause a major change in long-term fruit storage technology. More uses of the acoustic test method have been considered, for monitoring fruit maturity and harvest time, testing fruit samples or each individual fruit when entering the storage facilities, packaging house and auction, and in the supermarket. This approach may result in a full line of equipment for nondestructive quality control of fruits and vegetables, from the orchard or the greenhouse, through the entire sorting, grading and storage process, up to the consumer table. The developed technology offers a tool to determine the maturity of the fruits nondestructively by monitoring their acoustic response to mechanical impulse on the tree. A special device was built and preliminary tested in mango fruit. More development is needed to develop a portable, hand operated sensing method for this purpose. In North Carolina: Analysis method based on an Auto-Regressive (AR) model was developed for detecting the first resonance of fruit from their response to mechanical impulse. The algorithm included a routine that detects the first resonant frequency from as many sensors as possible. Experiments on Red Delicious apples were performed and their firmness was determined. The AR method allowed the detection of the first resonance. The method could be fast enough to be utilized in a real time sorting machine. Yet, further study is needed to look for improvement of the search algorithm of the methods. An impact contact-pressure measurement system and Neural Network (NN) identification method were developed to investigate the relationships between surface pressure distributions on selected fruits and their respective internal textural qualities. A piezoelectric dot-matrix pressure transducer was developed for the purpose of acquiring time-sampled pressure profiles during impact. The acquired data was transferred into a personal computer and accurate visualization of animated data were presented. Preliminary test with 10 apples has been performed. Measurement were made by the contact-pressure transducer in two different positions. Complementary measurements were made on the same apples by using the Firmalon and Magness Taylor (MT) testers. Three-layer neural network was designed. 2/3 of the contact-pressure data were used as training input data and corresponding MT data as training target data. The remaining data were used as NN checking data. Six samples randomly chosen from the ten measured samples and their corresponding Firmalon values were used as the NN training and target data, respectively. The remaining four samples' data were input to the NN. The NN results consistent with the Firmness Tester values. So, if more training data would be obtained, the output should be more accurate. In addition, the Firmness Tester values do not consistent with MT firmness tester values. The NN method developed in this study appears to be a useful tool to emulate the MT Firmness test results without destroying the apple samples. To get more accurate estimation of MT firmness a much larger training data set is required. When the larger sensitive area of the pressure sensor being developed in this project becomes available, the entire contact 'shape' will provide additional information and the neural network results would be more accurate. It has been shown that the impact information can be utilized in the determination of internal quality factors of fruit. Until now,

Full textAbstract:
This master thesis explores the challenges for waste management business models in the field of textiles regarding the requirements of the circular economy, as well as improvement potentials in the current framework conditions. It is concerned with the research question: "Is it advisable to change the frame-work conditions at meso or macro level, with regard to business models for waste management companies in the textile sector that are oriented towards the requirements of the circular economy, and - if so - in what way?” The approach of the study is based on the delta analysis of the e Society for Institutional Analysis at the Darmstadt University of Applied Sciences. It compares the target state of the normative requirements with the actual state of the textile and waste management framework conditions and attempts to identify the gaps (the delta). Based on the delta, it develops approaches that are intended to help reduce the gaps. The thesis develops three business models for the target year 2025 in different areas: an exchange platform for sorters, recyclers and designers, an automatic sorting plant and a plant for fibre-to-fibre recycling of mixed materials. It is becoming clear that these business models cannot meet the target requirements for the circular economy. The analysis identifies the remaining gaps in the framework conditions as the main problem. For example, insufficient innovation impulses and the lack of competitiveness of secondary raw materials inhibit the actors from applying and using new technologies and business models. Restricted access to knowledge and information, as well as a lack of transparency between the actors, also prove to be problematic. In order to answer the research question, the study recommends altering the framework conditions at meso and macro level. It proposes a platform for cooperation between designers, the introduction of a material declaration system and an eco-design guideline for textiles as possible development options. In addition, this work offers a matrix of criteria to help the actors test and improve their new waste management business models regarding their suitability for the circular economy. The analysis is carried out from an outsider's perspective on the entire textile industry. It therefore cannot cover and deal with all aspects and individual circumstances of each player in detail. The necessary changes in the framework conditions that have been identified can therefore be used as a basis for further investigations.
