IMPROVING THE QUALITY OF SELF-ORGANIZING MAP BY “ DIFFERENT ELEMENTS ” COMPETITIVE STRATEGY

A Self-Organizing Map (SOM) has good quality when both of its measures, quantization error (QE) and topographic error (TE), are small. Many researchers have tried to reduce these measures by improving SOM’s learning algorithm, however, most results only decrease either QE or TE. In this paper, a method to improve the quality of the map obtained when the SOM’s learning algorithm ended is proposed. The proposed method re-adjusts weight vector of each neuron according to cluster’s center that neuron represents and optimizes clusters by “different elements” competitive strategy. In this method, QE always decreases each time the competition “different elements” occurs between all neurons, TE may reduce when the competition “different elements” occurs between adjacent neighbors. The experiments are performed on assumed datasets and real datasets. As the results, the average reduction ratio of QE is from 50% to 60%, TE gets the average reduction ratio from 10% to 20%. This reduction ratio is larger than some other solutions but does not need to adjust the parameters for each specific dataset.
The climatic impacts and humanitarian problems from the use of the UK ’ s nuclear weapons

the latest climate models to re-examine the issue of the ‘nuclear winter’, the global climatic effect likely to be triggered by a nuclear war. On the basis of these studies, I estimated the global cooling that could occur if all the nuclear warheads carried by just one of the UK’s Trident submarines were launched. My analysis was published by SGR in 2008 [i], following an earlier article in the Bulletin of the Atomic Scientists, and is reproduced on the following pages. In short, a global temperature drop of at least 1.5°C could be expected – causing extremely serious social and environmental problems. Below I update my analysis, based on a recent reduction in the maximum number of warheads carried by each submarine, and further information about the possible targets against which the UK’s nuclear weapons might be used.
Survey of Dutch soil organic matter research with regard to humification and degradation rates in arable land

After the introduction of mineral fertilisers in the last century, concern has often been expressed that this would lead to a decline of the organic matter level in arable soil resulting in a general soil deterioration. These warning notes sounded every time major changes in the agricultural production system took place, such as: farmers doing away with cattle, and therefore with manuring their arable land, and turning their pastures into arable land; the large increase in fertiliser use; increased mechanisation which, among others, demanded better and deeper drainage of the soil and thus would accelerate organic matter degradation; the trend toward a simplified rotation system with an increase in the number of root crops, leaving a smaller amount of crop residues in the soil, and sometimes less or no green manures being grown.
Simulation of Delayed Failure in Naturally Deposited Clay Ground by Soil-water Coupled Finite Deformation Analysis Taking Inertial Forces into Consideration Simulation

A bearing capacity analysis was carried out for a highly structured naturally deposited clay ground using the soil-water coupled finite deformation analysis code GEOASIA, which takes inertial forces into consideration and employs the SYS Cam-clay model, which is capable of describing the work of the soil skeleton structure. The following results and conclusions were obtained. 1) When a ground that exhibited localization of deformation and formation of a circular slip failure accompanied by load reduction as a result of loading by displacement control was loaded by load control, it failed dynamically in association with acceleration motions after reaching the peak load obtained during displacement control. To date, the bearing capacity problem has only been dealt with quasi-statically, but it is essential to take inertial forces into consideration in order to reproduce this type of failure behavior. 2) Using the analysis code, it was possible to reproduce the behavior before, during, and after the delayed failure phenomenon, as well as whether or not there is a load threshold for occurrence of delayed failure. To reproduce this type of phenomenon, a time-dependent constitutive equation is not necessarily required. RÉSUMÉ : Nous avons effectué l'analyse de capacité portante d'un sol d'argile naturelle sédimentaire ayant développé une structure à l'aide du programme GEOASIA d'analyse des déformations finies de squelette couplé eau-sol en tenant compte de la force d'inertie, et équipé du modèle SYS Cam-clay qui inclut la fonction de la structure du squelette du sol. Les résultats sont indiqués ci-dessous. 1) La soumission d'une charge au sol par commande de déplacement produit une localisation des déformations et simultanément la création d'une rupture coulissante en forme d'arc alors qu'en soumettant une charge par commande de charge, après avoir atteint le pic de chargement de la commande de déplacement, le sol subit une rupture dynamiquement avec l'accélération de l'activité. Jusqu'à présent, le problème de la capacité portante n'avait été traité que de manière quasi-statique mais afin de reproduire ces comportements de rupture il est nécessaire de prendre en compte de la force d'inertie. 2) Il est possible de reproduire le comportement avant, pendant et après la rupture du phénomène de rupture différée à l'aide du même programme d'analyse du seuil de charge s'il y a rupture différée. Pour reproduire ce phénomène, une équation constitutive dépendante du temps n'est pas forcément nécessaire.
AUTOMATING FPGA-BASED SYSTEM IMPLEMENTATION WITH COMMON INTERFACING

A challenge in component-based design is reliably and efficiently instantiating the transport and any translation functions required to transfer data between each component comprising the entire system. While the components may involve complicated manipulation of the data stream, the transport between them is typically much simpler. It can be abstractly defined in terms of data flow characteristics qualified by various properties of the targeted hardware platform. If the interface between the components of the system is well defined, automated tools can easily create the required transport based on a high level structural view of the system. This paper will describe a complete solution for automating the process of interconnecting all components of a system. First, we defined a set of three component interfaces based on Open Core Protocol (a low-level hardware interface definition standard) that, as a group, we refer to as Common Interfaces. Next, we defined an XML representation and created a GUI for describing the highlevel characteristics of the component interfaces and the interconnection of the components within the system. Lastly, we developed scripts to generate hardware description language source for the entire system besides the components. In so doing, we have freed the system designer to focus on developing the components, the heart of the system.ly defined in terms of data flow characteristics qualified by various properties of the targeted hardware platform.

EVOLUTIONARY ALGORITHMS FOR PID CONTROLLER DESIGN OF BOOST INVERTER IN PHOTOVOLTAIC APPLICATIONS

This paper proposes a design method for determining the optimal proportional-integral-derivative (PID) controller parameters of a boost inverter using the evolutionary algorithms for photovoltaic (PV) system. This paper details how to employ the evolutionary algorithm to search efficiently the optimal PID controller parameters of boost inverter. A time-domain performance criterion function was used in order to assist estimating the optimal PID controller parameters. Comparison is made among the genetic algorithm (GA), Ant Colony Optimization (ACO), Artificial Bee Colony algorithm (ABC) and Particle Swarm Optimization (PSO). It is found that Particle Swarm Optimization algorithm based PID controller was indeed more efficient and robust in improving the step response of a boost inverter. Simulations are carried out and results are presented to validate the performance of the PID controller.
LINKING OWNERSHIP STRUCTURE AND BRANDING STRATEGY TO FINANCIAL PERFORMANCE AND STABILITY: CASE OF FRENCH WINE COOPERATIVES1

This research explores the impact of branding on financial performance of a firm while taking into account its ownership structure. Using the decisional theory, we apply a normative approach to better explain the incentives and constraints of branding in two types of firms: Cooperatives and Investor Owned Firms (IOFs). We adopt a quantitative analysis, using a survey of 207 French firms in the wine sector, combing its data with financial information. We show that cooperatives are more constrained to brand, therefore, they invest more in collective branding whereas IOFs are more likely to invest in specific branding. Additionally, we find that branded firms have lower financial and commercial performance. Finally, we find that the main factor contributing to the stability of financial performance is the cooperative ownership structure rather than the creation of a brand.
9 Cell Therapy and Tissular Engineering to Regenerate Articular Cartilage

Osteoarthritis (OA) is a degenerative joint disease characterized by deterioration in the integrity of hyaline cartilage and subchondral bone (Ishiguro et al., 2002). OA is the most common articular pathology and the most frequent cause of disability. Genetic, metabolic and physical factors interact in the pathogenesis of OA producing cartilage damage. The incidence of OA is directly related to age and is expected to increase along with the median age of the population (Brooks, 2002). The capacity for the self-repair of articular cartilage is very limited, mainly because it is an avascular tissue (Mankin, 1982; Resinger et al., 2004; Fuentes-Boquete et al., 2008). Consequently, progenitor cells in blood and marrow cannot enter the damaged region to influence or contribute to the reparative process (Steinert et al., 2007). There are a lack of reliable techniques and methods to stimulate growth of new tissue to treat degenerative diseases and trauma (Wong et al., 2005). Modalities of cellular therapy to repair focal articular cartilage defects include the implantation of cells with chondrogenic capacity (Koga et al., 2008) and creating access to the bone-marrow. Of the numerous treatments available nowadays, no technique has yet been able to consistently regenerate normal hyaline cartilage. Current treatments generate a fibrocartilaginous tissue that is different from hyaline articular cartilage. To avoid the need for prosthetic replacement, different cell treatments have been developed with the aim of forming a repair tissue with structural, biochemical, and functional characteristics equivalent to those of natural articular cartilage (Fuentes-Boquete et al., 2007). This review summarizes the options for treatment of articular cartilage defects from both the experimental and clinical perspective (Fig. 1).

This paper aims to discover benefits and challenges faced by English teachers along their involvement in Teacher Professional Development (TPD) programs in Yogyakarta. There were 73 senior high school English teachers in Yogyakarta city and Sleman regency as the participants in this research. The data were obtained through both quantitative and qualitative methods, distributed questionnaires and followed by in-depth interviews to five participants. The results of this paper firstly showed that some TPD programs were found to be beneficial perceived by the English teachers. Secondly, there were two major challenges faced by the participants, namely teachers’ workload & time management and also the lack of effective follow up programs.
Similarity-based Weighting Approach for Transfer Learning

Transfer learning addresses learning problems in which the training and test data are across different domains, i.e. under different distributions or feature spaces. The objective is to transfer useful knowledge in the abundant source-domain data to benefit learning in the target domain. In this report, we present a simple approach to enable instance-based transfer learning. The key idea is to find some source-domain instances similar to target-domain instances using a classifier learnt on target-domain training data. Those similar instances are then given positive weights and integrated into the target-domain training set to build a better classifier for the target domain. The main advantage of our approach over existing weighting approaches lies that the instance-weight is efficiently determined in a heuristic way. Also, experimental results reveal that the approach is highly effective and robust.
BERT + Verify

BERT provides powerful natural language understanding, and forms the backbone of many state-of-the-art question answering systems. However, as Hu et. al. found in their seminal paper Read + Verify: Machine Reading Comprehension with Unanswerable Questions, they could significantly improve performance by adding a distinct answer verification step after the answer generation step. This let them achieve state-of-the-art results on the SQuAD question answering dataset at the time. However, their system used a precursor of BERT, ELMO. We update their methodology to use BERT as a verifier and bidirectional attention flow as an answer generator. We find that although it outperforms bidirectional attention flow without a verifier, it takes an order of magnitude longer to train and the gains are minimal.

Characterization of Streptococcus suis through serotyping, SE-AFLP and virulence profile. Pesquisa Veterinária Brasileira 36(8):701-704. Laboratório de Sanidade Suína e Virologia, Faculdade de Medicina Veterinária e Zootecnia, Universidade de São Paulo, Av. Prof. Dr. Orlando Marques de Paiva 87, Cidade Universitária, São Paulo, SP 05508-270, Brazil. E-mail: morenoam@usp.br Streptococcus suis is one of most important pathogens in the swine industry worldwide. Despite its importance, studies of S. suis characterization in South America are still rare. This study evaluates S. suis isolates from distinct Brazilian states, from 1999 to 2004, and its molecular and serological characterization. A total of 174 isolates were studied. S. suis identification was confirmed by PCR and isolates were further serotyped and genotyped by SE-AFLP and amplification of virulence markers. Serotype 1, 2, 3, 4, 7, 18, 22 and 32 were identified among the studied isolates, and only 4% were characterized as non-typeable. The mrp+/epf+/sly+ genotype was the most frequent. The SE-AFLP analysis resulted in 29 patterns distributed in three main clusters with over 65% of genetic similarity. Isolates presented a slight tendency to cluster according to serotype and origin; however, no further correlation with virulence genotypes was observed.
Analysis of Contemporary Theories When Encountering the Context in Architectural Design

Problem Statement: From the beginning of the history of architecture, unconsciously or consciously, the issue of context has affected the architectural design. With the emergence of modern architecture, some theories were discussed about how to encounter the context in design and by criticizing those theories in the postmodern era and the advent of the Contextualism term in the architecture literature became a controversial topic among the thinkers of this field. Aims: This study has aimed at categorizing and analyzing the approaches to encountering the context in order to use it in design. Methodology: In this descriptive-analytical study regard, using library references, an overview of the theoriststheorists’ approaches has been first mentioned in order to achieve a comprehensive classification . Then different theories about the critique of these approaches have been then investigated; and finally, these theories have been concluded and their fundamental points have been extracted and presented. Conclusion: The results indicate that while emphasizing principles including these principles can be summarized in three items of avoiding excess and negligence, simultaneous attention to the historical context and contemporary context, as well as the maintenance of integrity and continuity, the investigated theories support the contextualism.
1 Efficient Lock-Free Durable Sets

Non-volatile memory is expected to co-exist or replace DRAM in upcoming architectures. Durable concurrent data structures for non-volatile memories are essential building blocks for constructing adequate software for use with these architectures. In this paper, we propose a new approach for durable concurrent sets and use this approach to build the most efficient durable hash tables available today. Evaluation shows a performance improvement factor of up to 3.3x over existing technology.
Reconfigurable near-field test coil for HF RFID measurement system

Author Sami Rautanen Title Reconfigurable near-field test coil for HF RFID measurement system Degree programme Master’s Programme in Nano and Radio Sciences Major Radio Science and Engineering Code of major ELEC3038 Supervisor Prof. Ville Viikari Advisor D.Sc. (tech) Jesse Tuominen Date 10.6. 2019 Number of pages 54 Language English Abstract This Master’s thesis studies the possibilities of realising a reconfigurable near-field test coil for HF RFID measurement system. The object is to design a working prototype with three nested coils and a tunable matching circuit. During the project, many different approaches are investigated and the most promising implementations are chosen for the prototype. Since a product is to be made based on the results of this thesis, the costs, PCB size, manufacturability and component lead times are always taken into consideration when making decisions. In addition to the two near-field coils already in use, a new smaller coil is designed for measuring very small HF RFID tags. The matching circuit for the coils is realised with two different designs: electromechanical relays and PIN diode switches. The switches are used to control resistor and capacitor arrays. 5 V voltages are used for controlling the switches and a microprocessor board with ATmega2560 is used to control the voltages. The component values are based on simulation results. Neither of the two versions of the prototype fulfilled every requirement. The control and supply voltages are working and are easily integrated to the HF RFID measurement system. The inductances and magnetic field strength of the coils are in line with calculated results. However, the resonance frequency tuning range of the prototypes is too low, 8—13.5 MHz. The required tuning range would have been 10—17 MHz. Nonetheless, the Q-factor tuning is successful, and the frequency tuning steps are appropriate. As a result, proposal for designing a product is made based on the results of this project.
KINETICS OF THE FREE LEG JOINTS OF LONG DISTANCE SPEED SKATERS DURING CURVING

The innovation of the skating technique by the klapskate resulted in the remarkable improvement in speed skaters’ performance. This new skate is equipped with a hinge, between the shoe and the blade of the skate. The skate permits rotation of the shoe relative to the blade and allows the skater to perform a plantar flexion at the end of the push-off while the full blade continues to glide on the ice (van Ingen Schenau et al.; 1996, de Koning et al.; 2000). It was reported that these advantages caused the skaters increase the work per stroke and the mean power output (Houdijk et al., 2000). It is important in long distance speed skating to maintain high speed as long as possible over the racing distance. Although there have been many biomechanical studies on speed skating, only a little information on the technique of long distance speed skating has been obtained. Van Ingen Schenau et al. (1983) reported that the declining rate of the stroke frequency and work per stroke during 3000 m race in the elite skaters were much smaller than that of the ordinary skaters. Moreover, de Boer et al. (1987) reported that the technical characteristics of the elite long distance speed skaters in the curve were the shorter time of the stroke and push-off and the greater push-off angle. However, skating techniques for elite skaters who could maintain the high skating velocity were not enough clear because these suggestions were derived from comparing between the elite and trained group.
ork-family conflict , self-efficacy , and emotional exhaustion : A test f longitudinal effects

Based upon the revised Job Demands and Resources Model (2008) we aim first, to test the relations between work-family conflict and emotional exhaustion across time and second, to determine the role of professional self-efficacy in this relation. A longitudinal study was conducted in two times, with a year of interval in a Spanish Army sample (n = 242). To test the causal relations between work-family and emotional exhaustion three models are tested: normal causal, reversed causal, and causal reciprocal. To test the role of professional self-efficacy in the relation between work-family conflict and emotional exhaustion four alternative models are tested: independence, antecedent, mediation, and independence plus antecedent models. Structural Equation Modeling results confirm the simultaneous reciprocal effects model as it fits the data better than the normal causal or the reverse causal models. This result suggests a spiral process, where work-family conflict predicts emotional exhaustion and at the same time emotional exhaustion increases work-family conflict. Likewise, this article contributes to clarifying the role of selfefficacy in the complex relationship between work-family conflict and emotional exhaustion. © 2015 Colegio Oficial de Psicólogos de Madrid.
