A Survey on Feature Selection Using FAST Approach to Reduce High Dimensional Data

Feature selection is a process of identifying the most useful subset of features.The survey summarising most of the feature selection methods and algorithms. Feature selection is the process of identifying a subset of most useful features. Typically the feature selection methods consist of four basic main steps and classify different existing feature selection algorithms . It is defined in terms of generation methods and evaluation functions. Most useful or representative methods are chosen from each category. The strength and weakness of different feature selection algorithms are explained. The aim here is to select some of the feature to form a feature subset. Feature selection has been effective technique in dimensionality reduction, removing irrelevant data, increasing learning accuracy, and improving comprehensibility. Increase in dimensionality of data imposes a severe challenge to many existing feature selection methods with respect to efficiency and effectiveness. To find a subset of features, the efficiency is related to time, the effectiveness is related to the quality of the subset of features. Existing feature selection algorithm removes only irrelevant features. But FAST algorithm removes both Irrelevant and redundant features. This survey mainly focuses on Comparison of various techniques and algorithms for feature selection process.
An Introductory Course in Electronic Engineering Using a Collaborative Problem Based Learning Approach in a Studio Environment

The City University of Hong Kong has been running a 3 year degree programme in mechatronic engineering since 1992 - the first in Asia. Over that time the content and presentation of the programme has changed to reflect the continuing evolution of the Pearl River delta and mainland China in particular. In 2002 a revised programme was introduced that resulted a substantially changed degree structure. One of the elements of this was the development of a new 'core' two-semester course in electronic engineering that was to be taken in the first year of the programme. This new course would be heavily problem-based learning in nature, with the use of small groups working in a collaborative manner. At the same time, it was decided to use the integrated teaching studio paradigm that had been successfully introduced some years previously. The new course combines simulation and practical laboratory around a number of problem-based learning objectives. This paper presents the results of the first year of implementation with reference to the new programme, as well as the resulting further development of the studio-based teaching techniques.
Opinions of the students of the University of the Third Age on selected health behaviors and social support – A comparative analysis

Background: ‪In the reflection on old age, the issue of activating the elderly and incorporating them into social life in order to counteract social exclusion and all forms of discrimination is clearly marked. The study aimed at getting to know the opinions of the students of the University of the Third Age on preferred health behaviors and social support. Material/Methods: ‪The study group involved 130 students of the University of the Third Age. The vast majority were women (90%, n = 117), and the mean age was 65.4 ±5.9 years. The study used a questionnaire containing questions about sociodemographic data, selected health behaviors and social support. The p level of < 0.05 was considered significant for the interpretation of hypotheses. Results: ‪ The place of residence does not have a significant impact on the activities undertaken among the respondents. Walks and organized gymnastics were the most frequently chosen form of physical activity, which people aged 66-70 often did. Passive rest of a significant percentage of students was associated with watching television. The most frequently occurring condition was hypertension. Emotional support was received by the respondents from the family/relatives (40% of respondents); a similar percentage of people (about 37%) declared that they had no expectations in this regard. The percentage of people using institutional support in both subgroups was significantly different, with respondents in the town of Ketrzyn (northeastern Poland) using this form more often. Conclusions: Surveyed students lead an inadequately active lifestyle. Factors such as age, place of residence and education did not affect physical activity.
Network Functions At The Edge (NetFATE): Design and Implementation Issues

The rapid evolution of low-cost standard hardware coupled with the diffusion and the wide spread of new paradigms are stimulating Telco providers to explore the possibility to introduce new approaches like Software Defined Network (SDN) and Network Function Virtualization (NFV) into the next generation networks to provide their users with software defined networking services. This context leads to the deployment of highly flexible services, dynamically allocating the network functions over the network nodes. In this paper we explore the perspective to move those approaches toward the users, at the edge of the network, and propose an analytical model that will support network managers in the orchestration of virtualized functions, taking into account the service chains needed by traffic flows and the desired Quality of Experience (QoE). Moreover the paper proposes an architecture as proof-of-concept that implements these features at the edge of the network and makes the service management more flexible.
Juniper from Ethiopia Contains a Large‐Scale Precipitation Signal

Most semiarid regions are facing an increasing scarcity of woody vegetation due mainly to anthropogenic deforestation aggravated by climate changes. However, there is insufficient information to reconstruct past changes in climate and to evaluate the implications of future climate changes on the vegetation. Tree‐ring analysis is a powerful tool for studying tree age, population dynamics, growth behavior, and climate‐growth relationships among tropical tree species and for gaining information about the environmental forces driving growth change as well as for developing proxies for climate reconstruction. Wood anatomical and dendrochronological methods were used on Juniperus procera trees from two Ethiopian highland forests to check (i) whether tree‐ring series of juniper are cross‐datable and hence suitable for building tree‐ring chronologies, and if so, (ii) which climate factors mainly drive wood formation in juniper from this region. Visible growth layers of the juniper wood were shown to be annual rings. Tree‐ring sequences could be cross‐dated between trees growing at the same site and between trees growing at sites 350 km apart. Evidence was found that annual growth of junipers is mainly controlled by one climatic factor, precipitation. This strong precipitation influence proves the potential of African juniper chronologies for accurate climate reconstruction and points out the relevance of building a network of juniper chronologies across East Africa.
Gender Role in Performance of Small Scale Industry, Factors Affecting Women Entreprnereurs Growth in Delhi, Case Study

To identify the effect of the gender of owner on the small scale enterprise performance in Delhi (In- dia) is significant to investigate the relationship between gender and performance, and the difference in perfor- mance between male owned and female owned businesses were stated. Using parametric statistical techniques such as PLCC, the gender not only significantly effects the performance of the small business but shows a sig- nificant difference in the levels of performance between male owned businesses and females owned businesses. The National Foundation for Women Business Owners reported that between 1987 and 1994, the number of women-owned businesses grew by 78% and women-owned firms accounted for 36% of all firms. Although the growth in the number of women-owned businesses is encouraging, the size of such businesses remains small in terms of both revenues and number of employees, especially in comparison to male-owned businesses quite of- ten because of the lack of financial . Women owners still face hard challenges in small scale industries and the factors which influence the performance of female entrepreneur have been easily investigated by field study of various small scale industries in disparate locations in Delhi and confronted with several policies recently for-
Experimental Study of a 2-stage Parabolic Dish-Stirling Engine in Thailand

This paper conducted an experimental study of a laboratory-scaled 2-stage parabolic dish-Stirling engine. Experimental investigation of the system was performed, using an actual sun and a 2-stage parabolic dish concentrator as a heat source. Results from the performance testing by using a generator with a solar radiation and a double reflection parabolic dish solar concentrator in May 2014 indicated that the maximum concentrator efficiency is 26.291 %, the engine produced a maximum power of 0.359 W at 55.6 rpm, electrical power of 0.27 W, the generator efficiency at the maximum of 79.021 %, and the maximum overall brake thermal efficiency of 0.25033 %, approximately. The average heat input to concentrator is 1936.07 W and to the engine in an average of 180.28 W, respectively. The gross solar-toelectric conversion efficiency is 3.71 %.

Therefore, the conclusions can be applied to some commercial banks in some degree.
Evidence That gd versus ab T Cell Fate Determination Is Initiated Independently of T Cell Receptor Signaling

Two types of T cells, ab and gd , develop in vertebrates. How these two T cell lineages arise from a common thymic T progenitor is poorly understood. Differentiation of ab lineage T cells requires the surrogate a chain (pT a ), which associates with the T cell receptor (TCR) b chain to form the pre-TCR. gd lineage development does not appear to involve an obligatory surrogate chain, but instead requires productive rearrangement and expression of both TCR g and d genes. It has been proposed that the quality of signals transmitted by the pre-TCR and gd TCR are distinct and that these “instructive” signals determine the lineage fate of an uncommitted progenitor cell. Here we show that the thymic T progenitor cells (CD25 1 CD44 1 c-kit 1 CD3 2 CD4 2 CD8 2 thymocytes, termed pro-T cells) from young adult mice that have yet to express TCRs can be subdivided based on interleukin 7 receptor (IL-7R) expression. These subsets exhibit differential potential to develop into gd versus ab lineage (CD4 1 CD8 1 cells) in the thymus. Upon intrathymic injection, IL-7R neg-lo pro-T cells generated a 13-fold higher ratio of ab lineage to gd lineage cells than did IL-7R 1 pro-T cells. Much of this difference was due to a fivefold greater potential of IL-7R 1 pro-T cells to develop into TCR- gd T cells. Evidence indicates that this biased developmental potential is not a result of enhanced TCR- g gene rearrangement/expression in IL-7R 1 pro-T cells. These results indicate that the pro-T cells are heterogeneous in developmental potential before TCR gene rearrangement and suggest that in some precursor cells the initial lineage commitment is independent of TCR-mediated signals. input concentration for positive control tubulin PCRs was three- or fourfold lower than the starting concentrations for the gene of interest. Quantitation was performed using a Phosphor-Imager (Molecular Dynamics).
Maize (Zea mays L) cultivars nutrients concentration in leaves and stalks

There is pressure for crop residue removal for use as biofuel, animal feed, animal bedding and many other func¬tions which may increase nutrient export. However, there is little information about nutritional composition of maize stover considering the wide variability of cultivars used. The aim of this study was to evaluate the influence of maize cultivar on macronutrient (P, K, Ca, and Mg), micronutrient (Fe, Mn, Zn, and Cu) and Na concentration in leaves and stalks. We selected five pairs of cultivars, ranging from creole to high potential hybrid (creole, commer¬cial variety, single, double and triple cross hybrid). The cultivars were cropped under field conditions in high fertile Rhodic Ferralsol Eutric during two growing seasons. The first was characterized by severe drought (2005/2006) while the second with an abundant water supply (2006/2007). The leaf and stalk concentrations of P, K, Ca, Mg, Fe, Mn, Na, Zn, Cu, and C/P ratio were quantified at maturation stage. The results indicated that the P concen¬tration in leaves and stalks was inversely related to the technological level when simple hybrid was compared to creole cultivars. Similar behavior was observed for K in the leaf and stalk tissues. For Ca, Mg, Fe, Mn, Zn, Cu, and Na, it was not possible to establish the influence of maize selection. The C/P ratio of leaves and stalks underwent influence of the technological level with high values for simple hybrids. Maize selection seems to decrease P and K concentration for two major residue fractions, leaves and stalks.
Les évaluations de l’enseignement par les étudiants : vers une démarche abrégée

Cet article documente le processus de simplification de la demarche d’evaluation de l’enseignement par les etudiants. Cette simplification repose sur la conception d’un instrument abrege qui permet de porter des appreciations valides et fiables sur la qualite de l’enseignement. Une comparaison des qualites psychometriques entre l’instrument original et abrege est ainsi realisee. En conclusion, certaines modifications de la version abregee sont proposees, mais cette version represente neanmoins un substitut adequat a la version originale.
Lower hybrid current drive in the Tore Supra tokamak

To control and extract energy from nuclear fusion reactions, a mixture of deuterium and tritium gases must be heated to temperatures on the order of 100 million degrees, whilst maintaining a sufficiently high density. The main difficulty is to confine the ionised gases, i.e. plasma, until the rate of fusion reactions becomes large enough. In the most promising type of magnetic confinement fusion device, known as tokamak, steady state operation is highly desirable and can only be reached by non-inductive current drive methods, to complement the confining magnetic field. The best, experimentally proven method is by injection of lower hybrid (LH) waves that transfer momentum to the electrons in the plasma. In the Tore Supra tokamak, LH waves at a frequency of 3.7 GHz are coupled to the plasma for current drive using a fully active multijunction (FAM) launcher and/or a passive active multijunction (PAM) launcher, which was installed recently to test an antenna design relevant for ITER, which is the next large-scale tokamak currently under con- struction. In this thesis a study of fully non-inductive discharges with either the FAM or PAM launchers is performed, using a suite of codes specifically developed for LH current drive. Good agreement is found between experiments and simulations for such discharges at relatively low density. A detailed comparison of the LH power deposition profile and current drive efficiency with the two launchers is made. The par- allel refractive index spectra (n∥) of the two launchers are found to be noticeably different, resulting in different current profiles.
Bayesian heavy-tailed models and conflict resolution: A review

We review a substantial literature, spanning 50 years, concerning the resolution of conicts using Bayesian heavy-tailed models. Conicts arise when di¤erent sources of information about the model parameters (e.g. prior information, or the information in individual observations) suggest quite di¤erent plausible regions for those parameters. Traditional Bayesian models based on normal distributions or other conjugate structures typically resolve conicts by centring the posterior at some compromise position, but this is not a realistic resolution when it means that the posterior is then in conict with the di¤erent information sources. Bayesian modelling with heavy-tailed distributions has been shown to produce more reasonable conict resolution, typically by favouring one source of information over the other. The less favoured source is ultimately wholly or partially rejected as the conict becomes increasingly
Network Structural Properties for Cluster Long Run Dynamics. Evidence from Collaborative R&D Networks in the European Mobile Phone Industry

In a recent literature, the structural properties of knowledge networks have been pointed out as a critical factor for cluster structural changes and long-run dynamics. Mixing evolutionary economic geography and network-based approach of clusters, this contribution aims at capturing and discussing the particular influence of hierarchy (degree distribution) and assortativity (degree correlation) in the innovative capabilities of clusters along the industry life cycle. We test our propositions in the field of the mobile phone industry in Europe from 1988 to 2008. We use EPO PATSTAT and OECD REGPAT to capture cluster trends, and R&D relations from European Framework Programs to capture knowledge networks and their evolving structural properties. Our findings provide new insights to understand the organization of clusters over time to perform along the industry life cycle.
Geomorphology and hydrochemistry of 12 Alpine lakes in the Gran Paradiso National Park, Italy

Twelve Alpine lakes located in the Gran Paradiso National Park, in the western Italian Alps, were sampled during the ice free period in 2008 and analysed for the main morphological, chemical and physical variables in relation to the characteristics of their watershed, with the aim to create a reference database for present and future ecological studies and to support conservation politics with scientific data. The results highlighted that weathering process and direct precipitation input are the main factors determining the hydrochemistry of the studied lakes; moreover the morphological characteristics highly affects the physical properties of the lakes starting from stratification process. The acidification status, the atmospheric input of N compounds and the supply of nutrients were considered in detail. The studied lakes seem to be well preserved by acidification risk. Comparing data from Gran Paradiso National Park with data from European mountain regions ranging in N deposition rates, allows to consider long range anthropogenic impact: the detection of relative low Total Nitrogen (TN) concentration is not necessarily a synonym of a soft impact of long range pollutants, being the final nitrogen concentration dependent from retention process, closely related to catchment characteristics, besides N deposition rates; moreover the dominance of Inorganic Nitrogen (IN) on Organic Nitrogen (ON) highlights that the lakes are interested by N deposition and probably by long range transport of pollutants produced in the urbanized area surrounding the massif. However the Gran Paradiso National Park area is by far less affected by atmospheric pollutants than other Alpine regions, as the Central Alps. Total Phosphorus (TP) concentration in Gran Paradiso lakes (1-13 μg L-1, mean level = 4 μg L-1) is an index of oligotrophic and ultraoligotrophic conditions and according to Redfield's ratio phosphorus is mainly the phytoplankton growth limiting element, assuming a key role in biological processes and food-web dynamics; the high TN:TP ratio values detected in the studied lakes reflects the low N retention capacity of alpine sparse vegetation by comparison with prairies or forests.
Effect of peripheral λ-carrageenan-induced inflammation on the blood-spinal cord barrier and the tight junction protein occludin

Die Blut-Hirn und Blut-Ruckenmarks-Schranke sind durch eine komplexe Interaktion zwischen Endothelzellen und verschiedenen Zelltypen des Zentralen Nervensystems charakterisiert. Sogenannte Tight Junctions zwischen den Endothelzellen bilden eine hochselektive parazellulare Diffusionsbarriere. Verschiedene Krankheiten, wie auch chronischer Schmerz haben einen starken Einfluss auf die Integritat der Blut-Ruckenmarks-Schranke. In dieser Studie wurde die Auswirkung einer peripheren Entzundung durch λ-Carrageen in mannlichen und weiblichen Ratten auf die Anordnung des Tight Junction Proteins Occludin und die Permeabilitat der Blut-Ruckenmarks-Schranke mit semiquantitativen Analysemethoden untersucht. Die Ergebnisse zeigten eine signifikante Abnahme der intakten Verteilung von Occludin in der dorsal lumbalen Region der Mannchen 72 Stunden nach der λ-Carrageen induzierten Entzundung. Bei Weibchen wurden keine Unterschiede gefunden. Der Austritt von Immunoglobulin G (IgG) aus dem Blut in das Ruckenmarkparenchym war 72 Stunden nach der Carrageen-Injection in der ipsilateral dorsal lumbalen Region in Mannchen und Weibchen signifikant erhoht, wobei dieser Effekt bei Weibchen hoher war. Bei der Untersuchung der thorakalen Region in Mannchen wurde auch dort ein erhohter IgG-Austritt festgestellt. Der direkte Vergleich zwischen IgG-Austritt und Verteilung von Occludin wies auf keinen Zusammenhang zwischen erhohter Permeabilitat der Blut-Ruckenmarks-Schranke und abnormaler Verteilung von Occludin hin. Diese Studie zeigte eine starke, jedoch verzogerte Auswirkung einer peripheren Entzundung – welche wahrend verschieden Krankheiten auftreten kann – auf die Integritat der Blut-Ruckenmarks-Schranke. Durch die erhohte Permeabilitat der Barriere konnen Pathogene in das Zentralnervensystem gelangen, aber auch Medikamente, die somit zu starkeren Nebenwirkungen fuhren konnen.
Field Test for Repellency of Cedarwood Oil and Cedrol to Little Fire Ants

Eastern redcedars (Juniperus virginiana L.) are an abundant renew- able resource and represent a potential source of valuable natural products that may serve as natural biocides. The aromatic wood can be extracted to obtain cedarwood oil (CWO) and critical carbon dioxide (CO 2 ) extraction of eastern redcedars gives both high yields and high quality CWO. In this study, CO 2 -derived CWO and cedrol, the most abundant component of CWO, were field-tested for repellency against the little fire ant (LFA), Wasmannia auropunctata Roger, in a Hawaiian macadamia orchard. Field tests were conducted using chopsticks baited with peanut-butter placed in established LFA trails on macadamia tree trunks and branches. The chopsticks and any ants present were collected after ca. 24 hours and the number of ants determined by visual counting. Four treatments were compared: Hexane only control; mineral oil; CWO; and cedrol. Control chopsticks and chopsticks treated with mineral oil had very high numbers of ants and were statistically equivalent. The CWO-treated chopsticks had significantly fewer LFAs than all the other treatments. Chopsticks treated with cedrol had fewer ants than the control chopsticks but more than the chopsticks treated with CWO. This research suggests that CWO extracts from J. virginianna may provide a renewable source of a natural ant repellent and could help manage this invasive pest.
