Assessment of tactical principles in youth soccer players of different age groups
Year: 2010

The aim of this study was to analyze tactical behaviours performed by youth soccer players of different age groups according to ten core tactical principles of the game, in order to understand characteristics of each age group and their differences. The sample comprised a total of 300 youth soccer players (60 U11, 60 U13, 60 U15, 60 U17 and 60 U20) who have performed 17,239 tactical actions. Three tactical measures were analyzed (number of tactical actions, efficiency of tactical behaviours and tactical performance indices) Kruskal Wallis H and Whitney U tests were applied to compare the values of tactical measures. Data reliability was assured by the Kappa of Cohen index. The results indicated forty statistical differences relative to the number of tactical actions performed, thirty two statistical differences regarding the efficiency of tactical behaviours, and twenty statistical differences concerning tactical performance indices. In conclusion, one can conclude that as the age group increased, the players had a greater participation in the game, namely by performing of more tactical actions. In addition, the U15 and U17 groups presented no statistical differences in the efficiency of their tactical behaviours, while the U17 and U20 groups exhibited the biggest differences in the tactical performance indices.  soccer, tactical performance, tactical behaviour, youth teams RESUMO Avaliacao dos principios tacticos em jovens futebolistas de diferentes idades O objetivo desse estudo consistiu na analise dos comportamentos taticos realizados por jovens jogadores de Futebol com base em dez principios taticos fundamentais do jogo, de modo a verificar as caracteristicas e as diferencas de cada grupo etario avaliado.

Efficient GAN Based Anomaly Detection
Venue: ArXiv
Year: 2018

Generative adversarial networks (GANs) are able to model the complex highdimensional distributions of real world data, which suggests they could be effective for anomaly detection. However, few works have explored the use of GANs for the anomaly detection task. We leverage recently developed GAN models for anomaly detection, and achieve state of the art performance on image and network intrusion datasets, while being several hundred fold faster at test time than the only published GAN based method.

EnglishThe main research objective of this work is the detection and evaluation of the social and environmental impact of the tourism industry on the Yasuni Biosphere Reserve. Yasuni Biosphere Reserve, well known due to its great biodiversity, is one of the largest and most important areas in the world. In fact, one hectare contains more species of trees and shrubs than all of North America taken together. Tourism, if managed properly, it is one of the main promoters of environmental conservation and economic development of local communities. Yet if it is not treated from a sustainable and environmentally friendly perspective, tourism can lead to important negative consequences for such communities. The conclusions drawn from this piece or research show evidence on the existence of important changes in the indigenous communities that inhabitant the Yasuni National Park and the Yasuni Biosphere Reserve. These changes are the result not only of tourism but also of oil extraction. francaisL'objectif principal de cette recherche est la detection et l'evaluation de l'impact social et environnemental que le secteur du tourisme a sur la reserve de biosphere de Yasuni.

Research on Library Digital Resource Evaluation System Based on Computer Multimedia Aid
Venue: 2021 IEEE International Conference on Power Electronics, Computer Applications (ICPECA)
Year: 2021

With the continuous increase in the total amount of library digital resource services, issues such as digital resources and performance evaluation have gradually attracted the attention of libraries. Traditionally, digital resource providers provide statistical data. However, due to benefits, the accuracy and authenticity of the data are open to question. Taking a particular university library as an example, the paper analyzes the information log of users accessing digital resources to obtain user information needs. It uses big data mining technology to extract user information needs and preferences, forming a trend map of user needs and digital resources matching. The study found that the system can provide an auxiliary decision making basis for subsequent purchases, provide data support for the evaluation of digital resource management in colleges and universities, and provide a scientific management model for the digital resource construction service system close to user experience.
On Generalizations of Commutativity
Year: 2015

This note is concerned with generalizations of commutativity. We introduce identity symmetric and right near commutative, and study basic structures of rings with such ring properties. It is shown that if R is an identity symmetric ring, then the set of all nilpotent elements forms a commutative subring of R. Moreover, identity symmetric regular rings are proved to be commutative. The near commutativity is shown to be not left right symmetric, and we study some conditions under which the near commutativity is left right symmetric. We also examine the near commutativity of skew trivial extensions, which has a role in this note.

Evidence Based Marketing: Using Principles from the Profit Impact of Market Strategies (PIMS) Project by Benchmarking UK Firms and Global Sportswear Manufacturers (GSMs) Marketing Expenditure (Nike, adidas, VF Corp, Under Armour, Puma, Anta and BasicNet SpA)
Year: 2019

This case is developmental, designed to expose students to a variety of marketing budgeting techniques and benchmarks from UK firms and the Global Sportswear Manufacturers; Nike, adidas, VF Corp, Under Armour, Puma, Anta and BasicNet SpA. The case is designed to enhance the understanding of marketing and the strategic value that can be offered by the marketing function. A large number of texts emphasise the financial aspects of budgeting as primarily relating to controlling costs as opposed to appreciating that the role of marketing budgeting should be to support strategic objectives over a period of time. It is extremely difficult to develop brands or develop organisations if the focus is based upon an annual planning cycle of which only short term objectives are assessed or where there is a bias towards short term thinking. There are complexities involved in buying products or services (for both consumers (B2C) and businesses (B2B) that can easily span multiple years and the positioning, or repositioning brands requires investment over multiple years.

An Electrochemical Gelation Method for Patterning Conductive PEDOT:PSS Hydrogels.
Venue: Advanced materials
Year: 2019

Due to their high water content and macroscopic connectivity, hydrogels made from the conducting polymer PEDOT:PSS are a promising platform from which to fabricate a wide range of porous conductive materials that are increasingly of interest in applications as varied as bioelectronics, regenerative medicine, and energy storage. Despite the promising properties of PEDOT:PSS based porous materials, the ability to pattern PEDOT:PSS hydrogels is still required to enable their integration with multifunctional and multichannel electronic devices. In this work, a novel electrochemical gelation "electrogelation" method is presented for rapidly patterning PEDOT:PSS hydrogels on any conductive template, including curved and 3D surfaces. High spatial resolution is achieved through use of a sacrificial metal layer to generate the hydrogel pattern, thereby enabling high performance conducting hydrogels and aerogels with desirable material properties to be introduced into increasingly complex device architectures.
Using EEG and Deep Learning to Predict Motion Sickness Under Wearing a Virtual Reality Device
Venue: IEEE Access
Year: 2020

Virtual Reality (VR) research has been widely applied in many fields. VR promises to deliver the experience that is beyond the user's imagination. One of the advantages of VR is the feeling it gives of being there. VR can provide experiences impossible in the real world, such as flying, diving in deep water, exploring outer space, or living with dinosaurs. Despite the improvements in the software and hardware, the problem of motion sickness remains. We implement a deep learning model to train and predict motion sickness. A questionnaire is a well known method to measure motion sickness. The weakness of the questionnaire is the measurement carried out after the user experiences motion sickness symptoms. By using the deep learning and EEG, the system will learn and classify motion sickness. The system learns the user's EEG pattern when they begin to feel the sickness symptoms. The system will be trained using deep learning to identify the sickness patterns in the future. By the EEG patterns, the system can predict the sickness symptoms before it occurs. Our model outperforms traditional models in loss values, accuracy, and F measure metrics in Roller Coaster. With other datasets, our model also performs well. Our model can achieve 82.83% accuracy from the dataset. We also found that the time steps to predict motion sickness during 5 minute periods is a suitable configuration.
The neuropeptide complement of the marine annelid Platynereis dumerilii
Venue: BMC Genomics
Year: 2013

BackgroundThe marine annelid Platynereis dumerilii is emerging as a powerful lophotrochozoan experimental model for evolutionary developmental biology (evo devo) and neurobiology. Recent studies revealed the presence of conserved neuropeptidergic signaling in Platynereis, including vasotocin/neurophysin, myoinhibitory peptide and opioid peptidergic systems. Despite these advances, comprehensive peptidome resources have yet to be reported.ResultsThe present work describes the neuropeptidome of Platynereis. We established a large transcriptome resource, consisting of stage specific next generation sequencing datasets and 77,419 expressed sequence tags. Using this information and a combination of bioinformatic searches and mass spectrometry analyses, we increased the known proneuropeptide (pNP) complement of Platynereis to 98. Based on sequence homology to metazoan pNPs, Platynereis pNPs were grouped into ancient eumetazoan, bilaterian, protostome, lophotrochozoan, and annelid families, and pNPs only found in Platynereis. Compared to the planarian Schmidtea mediterranea, the only other lophotrochozoan with a large scale pNP resource, Platynereis has a remarkably full complement of conserved pNPs, with 53 pNPs belonging to ancient eumetazoan or bilaterian families. Our comprehensive search strategy, combined with analyses of sequence conservation, also allowed us to define several novel lophotrochozoan and annelid pNP families. The stage specific transcriptome datasets also allowed us to map changes in pNP expression throughout the Platynereis life cycle.ConclusionThe large repertoire of conserved pNPs in Platynereis highlights the usefulness of annelids in comparative neuroendocrinology. This work establishes a reference dataset for comparative peptidomics in lophotrochozoans and provides the basis for future studies of Platynereis peptidergic signaling.
DIFFICULTIES OF SPEAKING THAT ARE ENCOUNTERED BY ENGLISH LANGUAGE STUDENTS AT AL MARGEB UNIVERSITY
Year: 2017

The aim of this paper is to explore the speaking difficulties encountered by English language students at Al Margeb University, and to discover the causes of such difficulties. Speaking English has been a vital importance in international communication. Speaking fluent English is a common problem among the nonnative speakers. The second language learners have gone through a variety of cases to learn how to speak not only correct grammar and using the right vocabulary but with correct accent and pronunciation. Many obstacles, therefore, have been known as the predictors of such a problem among the language learners. According to the review of literature, appropriate speaking instruction was found to be the learners' priority and a field in which they need more attention. In this paper the writer highlight the speaking difficulties encountered by English language students at Al Margeb University, which are considered to be the most urgent for every teacher, such as fear of mistakes, shyness, anxiety, lack of confidence and lack of motivation. This paper can be useful to teachers to consider their language learners' speaking needs in English language teaching and learning context.
Electricity consumption, urbanization, and economic growth in Nigeria: New insights from combined cointegration amidst structural breaks
Year: 2020

The study explores the link between electricity consumption, urbanization and economic growth in Nigeria from 1971 2014. The bounds test and the Bayer and Hanck (2013) cointegration tests affirm cointegrating relationship. Electricity consumption increases economic growth in both time periods, while the impact of urbanization appears to inhibit growth. The fully modified OLS (FMOLS) dynamic OLS (DOLS) and the canonical cointegrating regression (CCR) confirm the robustness of the findings. The vector error correction model (VECM) Granger causality test supports the neutrality hypothesis in the short run and the feedback hypothesis among the variables in the long run. Therefore, policies to ensure efficient electricity supply, curb rapid urbanization and promote sustainable economic growth were suggested.
David Temperley: Music and Probability, Cambridge, MA, MIT Press (2007)
Year: 2009

Can one use a pure statistical technique to create a model for music? Can one say that inherent probabilities shape music perception? David Temperley certainly thinks so and makes a good case to convince me. He acknowledges other researchers of having made such attempts, but his use of the Bayesian technique does not only make a lot of sense, he shows by means of examples, many of them, that his approach has great merit. "The book is intended to be accessible to a broad audience in music and cognitive science. I assume only a basic level of mathematical background; no prior knowledge of probability is required. With regard to music, also, a basic knowledge of music fundamentals is needed." according to the preface. In both instances this may be true, and in the case of statistical knowledge this certainly is true, although I have my doubts about whether the common reader would take the trouble to grind through some of the initial probabilistic examples, especially where the idea of entropy is explained. Fortunately it does not play any part in the remainder of the text except to understand the general notion of entropy. The principles behind the Bayesian approach are well explained, as well as the extensions which follow later in the book. With reference to musical knowledge my question is: What is meant by a basic knowledge? As statistician by trade, with little music theoretical background, some of the musical terms/notations which were used nonchalantly ensured that I read this book with my music dictionary as well as Wikipedia on the ready. The general content is well set out and reads fairly smoothly. This is, however not a late night bedtime book where one can pick and choose a subject or section from any chapter in an arbitrary way. I often had to retrace to previous sections in order to keep track of exactly what is being said and where it fits into the bigger picture. The information is dense in the sense that each sentence and statement counts. Thus, the use of pencil and paper (as well as a pocket calculator) is highly recommended to work with the author through the multitude of examples, one of the most important aspects of the book. If anything is unclear, take your time and make sure you work the related example in detail and everything falls into place. Much of the text is accompanied by figures and graphics which clear up any possible ambiguities. Another useful idea is to make notes with references as one goes along. This eventually saved me a lot of time. A last general remark is not out of place. As I was going through the book I could not rid myself of a feeling that I was missing some basic philosophy/drift in the text. Eventually I realized that although this text is described as a stand alone book, and it certainly is, several times references appear regarding Temperley's The Cognition of
Shock Wave Emission by Laser Generated Bubbles
Year: 2013

The phenomena occurring when short pulses of laser light are focused into a liquid are reviewed from the first findings after the invention of the laser to the present state of knowledge. Dielectric breakdown with plasma and bubble formation, the breakdown shock wave, bubble dynamics with expansion and collapse, and the bubble collapse shock wave or waves are addressed. Breakdown plasma lengths as a function of laser pulse energy are given. The propagation speed of the breakdown shock wave and the related shock peak pressure as determined by high speed streak recordings for nano pico and femtosecond laser pulses focused into water are discussed. Breakdown shock wave velocities up to 5000 m/s and peak pressures up to 100 kbar are reported for these monopolar acoustic pulses for laser pulse energies up to some 10 mJ. In tissue bipolar pressure pulses are observed due to the elasticity of the medium. The widths of the shock waves reach values in the range of tens of nano seconds to beyond 100 ns. The simultaneously generated breakdown bubble gets about half of the energy of the shock wave. Bubble energy rises linearly with the laser pulse energy with different slopes depending on the laser pulse duration. Equations for bubble dynamics are given and compared with laser induced bubble dynamics. Strength and width of bubble collapse shock waves measured with PVDF and fiber optic hydrophones are presented together with the breakdown shock waves. Similar values are obtained for both collapse and breakdown in the bulk of the liquid. Shock wave emission from bubbles collapsing near boundaries (solid and elastic) is discussed together with applications in cleaning and erosion or cell destruction.
