Identification of strategic factors of profitability in the Andalusian rural savings banks

The Rural Savings Banks (cajas rurales), although in their origin they played a primordial role in the financing of the agricultural sector and of the rural context in general, at the moment they are present in a wide variety of managerial sectors, thanks to an intense politics of diversification of their activity. These entities constitute the most excellent group inside the Spanish cooperative banking, so much for their territorial covering as for the volume of own and other people's resources. In this work we try to discover which strategy has been adopted by the sector of the Rural Savings Banks of Andalusia for the attainment of its objectives of profitability. In this paper we have elaborated it a methodology that allows us to carry out an analysis of the factors of profitability applying it to this sector. Finally conclusions are extracted.

Spatial data stream multiplexing scheme for high-throughput WLANs

A novel scheme using spatial data stream multiplexing (SDSM) in the upcoming multiple-input multipleoutput (MIMO)-based IEEE 802.11n physical layer is proposed. It is shown that with SDSM, the same data rate can be achieved by using less number of transmit and receive antennas and therefore this scheme can reduce the number of antennas which results in reducing mutual coupling effects, hardware costs and implementation complexities. The maximum data rates that can be achieved using a 2 * 2 MIMO system is 270 Mbps and for a 4 * 4 MIMO system is 540 Mbps. The same data rates can be achieved using the SDSM technique which reduces the 2 * 2 MIMO system to 1 * 1 SISO system and the 4 * 4 MIMO system to a 2 * 2 MIMO system

The last trip of the baby boomers: life and Death of Public Space in the cinema in the 1960s and 1970s

[Resumen] La generación nacida al final de la II Guerra Mundial llegó a su juventud arrastrada por la inercia del optimismo tecnocrático que había desarrollado la generación anterior. En un contexto de bonanza económica, la juventud se rebeló contra el sistema generando una nueva sensibilidad que daría lugar a diferentes respuestas contraculturales. En estos intentos de cambiar la sociedad, las ciudades asistieron a una recodificación de los espacios públicos. El espacio urbano, desacreditado bajo los ecos de “la muerte de la calle” promulgada por Le Corbusier, se reactivó como escenario de protesta y acción. Sin embargo, este resurgir de lo público se diluyó rápidamente al compás del desencanto juvenil. Una vez confirmada la imposibilidad de transformar el sistema, se produjo una búsqueda de otros territorios que el cine interpretó bajo dos estrategias: por un lado, la producción de espacios urbanos totalmente inhóspitos y desolados; por otro lado, un repliegue hacia lo individual reflejado en nuevas formas de habitar. Pequeñas comunidades, comunas y la vuelta a una vida rural controlada serán respuestas que, lejos de construir un ámbito público, resultarán finalmente el argumento que estaba buscando el sistema para la destrucción y reconfiguración del dominio público. El cine de finales de los años sesenta y principios de los setenta muestra el desencanto del final de un deseo que acaba identificándose con una iconografía de la destrucción, desamparo y vacío.[Abstract] The generation of those who were born at the end of the Second World War reached their youth carried by the inertia of the technocratic optimism developed by the previous generation. In a context of economic bonanza, the younger generation rebelled against the system, creating a new sensibility which would spawn different countercultural responses. Within these attempts to change society, cities witnessed a re-codification of public spaces. Urban space, discredited by the echoes of the ‘death of the street’ promoted by Le Corbusier, was reactivated as a stage for protest and action. However, this revival of public space was rapidly suffocated by the disenchantment of the youth. Once the impossibility to transform the system had been confirmed, a search for new territories started, which cinema interpreted following two strategies: on the one hand, through the production of definitely inhospitable and devastated urban spaces; on the other, by retreating to the individual sphere, which reflected on new modes of habitation. Small communities, communes, and the return to a controlled rural life would be responses which, far from building public realms, would ultimately provide the system with the argument it was looking for in order to destroy and reconfigure the public domain. The films of the late 1960s and early 1970s show the ultimate disenchantment of a desire that, in the end, was attached to an iconography of destruction, abandonment, and emptiness

Deep learning on genomics using NLP-oriented algorithms

This work provides a DNABERT-based solution inspired by NLP for the phage-bateria interaction (PBI) problem, as well as comprehensive literature review on the applied Deep Learning (DL) techniques. Intuitively, DNABERT is a novel approach to tackle DNA-based tasks built upon the popular BERT Transformer model. The report initially focuses on introducing and explaining core DL concepts that have been of paramount importance for developing the new ad-hoc models, providing also some background for understanding the current importance of Phage Therapy (PT) and how the PBI problem relates to PT. In brief, PT involves using phages to treat bacterial infections instead of antibiotics, and the focus of this work is to build a classifier based on DL capable of working with DNA information in text format from phages and bacteria, and of determining if a certain phage is likely to interact with (attack/neutralize) a certain bacterium. The first concept discussed is RNNs and, more concretely, LSTM networks. This type of neural network will be used as a starting point to reach the Transformer model by following the evolution of DL in the context of the NLP field. The attention mechanism and its implementation in the Transformer model are also discussed in detail. The document explains how this mechanism can be used to improve performance in various NLP tasks such as machine translation (MT), text summarization, and sentiment analysis, and, more importantly, how this mechanism can be also used to highlight the most relevant areas of a DNA sequence. This has been the main objective of the project, together with improving previous existing performance results of other neural models for the PBI problem. The motivation behind this research is also presented, along with important research questions that were explored and which guided the development, and there's an extensive section devoted to presenting the obtained results. Overall, this report aims to contribute to the field of Data Science by providing insights into how DL and NLP-oriented algorithms can be successfully applied to Genomics research for defeating great threats to human health such as superbugs. As a result of the developed work, 6 new DL models based on Transformers have been created, trained and evaluated, and the results have been satisfactory, achieving better results than previous neural models solving the same PBI problem. With the sake of encouraging future developments, at the end of the document there's a section devoted to pointing out possible promising future extensions of the work that has been carried out

CONCEPTUALIZING COMMUNITY IDENTITY THROUGH ANCIENT TEXTILES: TECHNOLOGY AND THE UNIFORMITY OF PRACTICE AT HUALCAYÁN, PERU

The goal of this thesis is to investigate a single textile assemblage from on site is homogeneously produced. In order to evaluate this, I looked at a sample of textiles and cordage recovered at the site of Hualcayán in the north-central highlands of Peru (ca. 1-1000 CE). Through a technical attribute analysis of metric traits I evaluate the degree of variability present in the overall sample. Making use of a community of practice approach, in which a group of individuals are engaged in participatory learning and share a common enterprise, I argue that homogeneous textiles represent a uniformity of practice. Indeed, it is through imitation and the passing on a non-discursive knowledge that certain community wide practices are reproduced. As a result, I hypothesize that a single community of weavers would produce relatively homogenous textiles, which would materialize in the form of a technologically uniform textile assemblage. Ultimately, I interpret such shared practices as connected to a specific type of group identity related to what it means to be a weaver in that particular setting. However, the results from Hualcayán demonstrate variability in cotton yarns, which I interpret as suggestive of interregional interaction between Hualcayán and coastal communities. Despite, this camelid yarns and overall weaving techniques are relatively uniform, which I argue points to a community of practice with regard to weaving and spinning camelid yarn

Effects of the machining in the surface integrity on the superaustenitic stainless steel

Orientadores: Paulo Roberto Mei, Anselmo Eduardo DinizDissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Engenharia MecanicaResumo: Foram investigados os efeitos das condições de usinagem em operação de torneamento na integridade superficial do aço inoxidável superaustenítico ASTM A744 Gr.CN3MN. A operação de acabamento foi o foco principal, porém também foram realizados estudos com a operação prévia, de desbaste. As principais variáveis no acabamento foram: ângulo de saída da ferramenta, velocidade de corte, profundidade de corte e avanço. No desbaste variou-se somente o ângulo de saída e a velocidade de corte. Os ensaios foram realizados em um torno horizontal CNC, utilizando fluido de corte. Os parâmetros analisados foram: microestrutura por microscopia ótica, rugosidade, encruamento por ensaio de microdureza e tensão residual por difração de raio-X. Para se estudar a resistência à corrosão por pites, superfícies usinadas foram imersas em solução de cloreto de ferro e examinadas no estereoscópio, medindo-se, por área, a densidade de pites e a perda de massa. Os resultados mostraram a presença de tensão residual de tração e de uma camada encruada em todas as superfícies usinadas. A redução da rugosidade elevou a resistência à corrosão por pite. A melhor combinação das condições de corte encontrada para obter os menores valores de rugosidade e de tensão residual de tração, no acabamento, para profundidade de corte de 0,2 ou 0,4 mm, foi a maior velocidade de corte (120 m/min), o menor avanço (0,1 mm/rot) e o maior ângulo de saída (10º), no desbaste; para a profundidade de corte de 2,5 mm e avanço de 0,25 mm/rot., foi a menor velocidade de corte (60 m/min) e o maior ângulo de saída (10º).Abstract: An investigation was made of the effects of the machining conditions employed in the turning operation on the surface integrity of ASTM A744 Grade CN3MN superaustenitic stainless steel. The main focus was the finishing operation, but studies were also carried out with a prior roughening operation. The main input variables in finishing were: tool rake angle, cutting speed, cutting depth and feed rate. The only input variables in the roughening operation were rake angle and cutting speed. The tests were conducted on a CNC horizontal lathe, using cutting fluid flood. The following parameters were analyzed: microstructure and roughness - examined by optical microscopy; work hardening - determined by microhardness measurements; and residual stress - analyzed by X-ray diffraction. To study the pitting corrosion resistance, machined surfaces were immersed in a ferric chloride solution and examined under a stereoscope, measuring the pits density and mass loss per area. The results revealed the presence of residual tensile stress and a hardened layer on all the machined surfaces. Reducing the roughness caused the pitting corrosion resistance to increase. To obtain the lowest values of roughness and residual tensile stress in finishing at cutting depths of 0.2 or 0.4 mm, the best combination of cutting conditions was the highest cutting speed (120 m/min), the lowest feed rate (0.1 mm/v), and the highest rake angle (10º). In roughening at a cutting depth of 2.5 mm and a feed rate of 0.25 mm/rot., the best combination was the lowest cutting speed (60 m/min) and the highest rake angle (10º).MestradoMateriais e Processos de FabricaçãoMestre em Engenharia Mecânic

Vibration analysis on driver’s seat of agricultural tractors during tillage tests

The vibration of the driver’s seat of agricultural tractors was investigated during three alternative tillage operations. Three tractors including a range of specifications were considered, at a range of forward speeds. The interactions between the tractors, implements and speeds were examined using the SPSS program and the GLM-ANOVA method. The results analysis indicated that the tractors played the first major role in vibration development in the lateral axis and was followed by the implements. In contrast, the implements played the first major role in the development of vibration in the horizontal axis and are followed by factor tractors. The statistically significant effect in vertical and horizontal axes shows the factor implements. In addition, the statistically significant effect in the vertical and lateral axes shows again the implements to be the most significant factor. Of the implements, the plough shows the highest vibration and displays statistically significant difference in comparison with the other implements
