Clustering Exploiting Sparse Representation Learner for Robust Classification

We propose a learning algorithm that gives a significant and consistent improvement in accuracy over the existing sparse representation learner. The proposed work is built on two essential properties of data. The first is that data points belonging to the same class span the same subspace (here onward referred as subspace property), and the second is that data points belonging to the same class are a part of the same cluster (here onward referred as clustering property). This paper proceeds by discussing a mode of breakdown for the sparse representation learner. Then, we introduce clustering exploiting sparse representation learner, which exploits both the subspace and clustering property to overcome the issues faced by sparse representation learner. The paper provides a strong geometric perspective of the classification scene involved with the different optimization frameworks discussed in the paper. To support our claims empirically, experiments where conducted comparing the sparse representation learner with the clustering exploiting sparse representation learner with a set of five diverse datasets. The final finding of this work is that clustering exploiting sparse learners could be safely assumed to give a improvement of 5% to 10% over the ordinary sparse representation learner.

Are Actiwatch Recordings Useful in the Diagnosis and Treatment of Attention Deficit Disorder and Hyperactivity

Attention deficit hyperactivity disorder has been investigated in numerous research studies ranging from incidence levels to the identification of the pervasiveness of the hyperactivity. However, the comorbidity of ADHD and sleep disturbance has been under investigated. Additionally, in some clinics, the data from the actigraphic monitoring is used to inform decisions about treatment. This study focused on the examination of actigraphic data from clinical cases, collectively in statistical analyses and individually in graphical analysis. Measure of sleep minutes, sleep start times, wake minutes, and activity levels were gathered from actigraphic recordings in five participants aged 10 to 18 years; data from two or the five participants that was complete was used in the study. Each participant was a patient of the clinic and informed consent was obtained. The results indicated elevated activity scores during the daytime and at night, comparatively, to same aged peers norms with sleep and psychological disorder diagnoses. There was considerable variability in sleep time and sleep efficiency scores in the three adolescent actigraphic recordings. All aggregated summary data and individual graphical analyses will be presented within the context of the sleep and child psychiatric literature.
Nutrient turnover at the hypoxic boundary: flux measurements and model representation for the bottom water environment of the Gulf of Riga, Baltic Sea

Abstract Experimental studies of intact sediment cores from the Gulf of Riga, Baltic Sea, were conducted to estimate the response of sediment nutrient fluxes to various near-bottom water oxygen conditions. The experiment was performed in the laboratory using a batch-mode assay type system on the sediment cores held at 4°C and oxygen concentrations maintained at 1, 2, 3, 4 and 5 mg l−1. The results from the experiment were subsequently used to optimise the fit of the sediment denitrification sub-model of the Gulf of Riga basin. Sediment- water fluxes of phosphate were low and directed out of the sediments under all treatments, demonstrating a general decreasing tendency with increasing nearbottom water oxygen concentration. The sediment-water fluxes of ammonium and nitrate + nitrite demonstrated opposing trends: ammonium fluxes decreased whereas nitrate + nitrite fluxes increased with rising near-bottom water oxygen concentration. The modelled fluxes agreed well with the measured ones, with correlation coefficients of 0.75, 0.63 and 0.88 for ammonium, nitrate + nitrite and phosphate fluxes respectively. The denitrification rate in sediments was simulated at oxygen concentrations from–2 to 10 mg l−1. At oxygen concentrations
FLOW CONTROL USING MOVING SURFACE AT THE LEADING EDGE OF AEROFOIL

Flow control is a significant topic of research in the field of aviation. Researchers in this field are continuously trying their best to find various flow control strategies in order to extract aerodynamic benefits by applying them. Applying moving surface at the leading edge of aerofoil is a type of strategy among the various types of active flow control strategies. In the present research work a rotating cylinder is added on the leading edge of the aerofoil as a moving surface in order to control the flow over its surface. The moving surface boundary layer control is applied to NACA 0018 airfoil for investigating its aerodynamic benefits and effectiveness. The moving surface is created by rotating a smooth cylinder at the leading edge of the aerofoil. The peripheral velocity of the cylinder injects momentum to the upper surface boundary layer of the aerofoil and thus delays its separation. This results in the gain in both the maximum lift coefficient and the stall angle. The work has been done at four different Reynolds Number i.e., at Re = 1.4 X 10^5, 1.85 X 10^5, 2.3 X 10^5, 2.8 X 10^5 at different angles of attack.

Evaluation of Antibacterial Potential of Honey Against Some Common Human Pathogens in North Gondar Zone of Ethiopia

The use of honey as a medicine has continued into present-day medicine. It has been shown that natural unheated honey has some broad-spectrum of antibacterial activity when tested against pathogenic bacteria. Different types of honey vary substantially in the potency of their antibacterial activity. The objective of this study is to evaluate the variations in the antibacterial potential of honey derived from North Gondar Zone against bacterial species commonly causing disease in human. Honeys were obtained from four districts of North Gondar Zone such as Chilga, Dembia, Debark and Gondar Zuria. The antibacterial potential of these honeys were assayed against five bacterial species (Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Salmonella typhi and Klebsiella pneumonia) using different concentrations (10v/v, 20v/v, 40v/v, 80v/v, and the undiluted honey). The standard disc diffusion methods were entertained. Undiluted and two-fold serial dilutions of honeys were tested to determine MIC using broth tube dilution methods through visual inspection and MBC were determined by sub culturing tubes showing no visible sign of growth/turbidity in MIC. Results showed that the zones of inhibition ranged from 0-21mm and honey from Gondar Zuria showed the highest antibacterial activity. There was a noticeable variation in the antibacterial potential of honeys at different concentrations (6.25-100%). All collections of honeys showed varied bacteriostatic and bactericidal activities and none of the honeys produced any effect on Klebsiella pneumoniae.
TESTING FOR THE EXISTENCE OF ANI(1) VECM REPRESENTATION

This paper proposes a method to test whether or not a VECM representation for a vector time series consisting of I (1) components, claimed in Granger representation theorem, is derived validly from a VMA as the DGP. The test is also available for the detection of the occurrence of multicointegration etc. Utilizing the idea of the nonparametric test employed by Phillips and Oulialis (1990) and Shintani (2001) to detect the existence of cointegration or the cointegrating rank, we construct a test statistic and establish its limiting properties with some similarity to of those tests. Finite sample performances of the test proposed are also investigated through some Monte Carlo experiment. 小瀧先生 10.7. 22 0:26 PM ページ 43
Improving E-Learning Performance through Social Communications

E-learning is a way of teaching by using modern communication mechanisms of computer networks, multimedia of (sound, image and graphics), electronic libraries and search mechanisms, as well as Internet portals, whether remote or in the classroom. The aim is to use all kinds of technology for the delivery of information to the student in the shortest time with less effort and greater benefit. In this paper, we attempt to solve the problem of isolating or missing social interactions of learner request, the professor perhaps not be always involved in the request and the missing of competitions and quality. To improve e-learning, it is recommended to it with sociality. In this paper, we used some algorithms such as (k-mean algorithm, decision-tree algorithm, Apriori algorithm, course rank algorithm) as tools to achieve our goals in finding most suitable friend and most suitable course for the user's.

Effect of Ocimum basilicum on mesenchymal stem cell proliferation and differentiation: Does the effect change according to niches?

It is a big issue that reduced bone density and large fractires in dentistry and orthopedics. Side effects caused by synthetic drugs lead to medical and ethical problems. Thus, plants and medicinal plant research take attention. Aim of this preliminary in vitro study is to investigate the effect of Ocimum basilicum extract on dental pulp (DP) and bone marrow (BM) derived mesenchymal stem cell (MSC) proliferation, osteogenic differentiation and immunological response to TNF-α. Human dental pulp tissue was obtained from patients (15-20 years of age) who were undergoing extraction of third molars for orthodontic reasons at the Department of Oral and Maxillofacial Surgery, University of Gazi University * . xCELLigence system was used to determine prolfieration of DP- and BM-MSCs. Adipogenic and osteogenic differentiation was shown and calcium concentration, osteocalcin and osteonectin levels were examined. I nflammatory environment was mimiced through TNF-α stimulation and IL-6 and IL-10 levels were defined by ELISA. Doubling time mwith O. basilicum was found in DP- MSCs (38 h) and BM-MSCs (76 h). IC50 value was shown as 148 µg/mL in DP-MSCs and 178 µg/mL in BM-MSCs. Calcium concentration of BM-MSCs was found decreased in O. basilicum treated groups. Level of ostoenectin was reduced in O. basilicum treated cells suggesting that the Extract accelerated the osteogenic differentiation. We suggest that O. basilicum could be a smart ostoeinductive agent where BM-MSCs should be investigated further. Rich flora of Turkey is an opportunity for us and encourangement can easily give inside to medicinal plant investigations. * B.30. 2.GUN. 0.20-122 Ethics Committee Report
Light limitation reduces tolerance to leaf damage in Datura stramonium

Question: Does light limitation reduce tolerance to leaf damage in the annual herb Datura stramonium? Hypothesis: Tolerance to leaf damage should be lower under light limitation (shade) than under full sunlight, because a reduction in leaf area and less exposure to light will limit carbon photo-assimilation and plants’ ability to maintain fitness. Organism: Jimsonweed, Datura stramonium L. (Solanaceae). Methods: Damaged and undamaged plants of ten full-sib families (N = 471 plants) were grown under two different light treatments, full sunlight (control) and 35% light reduction (shade). Total seed number produced per plant was used as an estimate of maternal plant fitness. To compare the effect of light reduction on tolerance, we used the index of tolerance (the difference in seed production between the damaged and undamaged treatment of each genetic family). We also evaluated the effect of defoliation and light limitation on photosynthetic activity (estimated as the chlorophyll content index) and leaf growth compensation (i.e. total leaf area, mean area per leaf, and leaf number), compensatory characters related to tolerance. Conclusions: Light limitation exacerbates the negative effect of leaf damage on plant fitness, producing a two-fold average reduction in tolerance. Moreover, compensatory growth was lower in the light-limited environment. Under high damage and light limitation, the evolution of higher tolerance to damage can be highly constrained.
SECRECY, PUBLICITY AND POWER: STRATEGIES OF OCCULT PRACTITIONERS AND UNIVERSITY MANAGERS

Various mystical, magical beliefs and practices, including some of those in the Transkei region of the Eastern Cape, are bound up with secrecy and mystery, exerting part of their influence by this means. This has certain metaphorical parallels with the way in which various managerial systems in market-driven, corporatised universities in South Africa and elsewhere tend to employ obscurity and mystification as a form of power and control. However, there are possible ways of transcending confinement within the verbal-ideological control mechanisms of corporate managerialism, with their shadowy, opaque qualities that sow confusion and bring about disempowerment, and the study of folklore can play a significant role in this regard.
SAGE version 7.0 algorithm: application to SAGE II

Abstract. This paper details the SAGE (Stratospheric Aerosol and Gas Experiment) version 7.0 algorithm and how it is applied to SAGE II. Changes made between the previous (v6.2) and current (v7.0) versions are described and their impacts on the data products explained for both coincident event comparisons and time-series analysis. Users of the data will notice a general improvement in all of the SAGE II data products, which are now in better agreement with more modern data sets (e.g., SAGE III) and more robust for use with trend studies.
Effects of 1997 Indonesian forest fires on tropospheric ozone enhancement, radiative forcing, and temperature change over the Hong Kong region

Tropospheric ozone enhancements were measured over Hong Kong (22.2°N, 114.3°E) by electrochemical concentration cell ozonesondes during the 1997 period when many forest fires were burning in Indonesia. The enhancements have a maximum ozone concentration of up to 130 ppbv and an ozone-enhanced layer depth of 10 km. We used Total Ozone Mapping Spectrometer, advanced very high resolution radiometer satellite image, and back air trajectory to identify the source region and the transport pattern of ozone. The strong tropospheric ozone enhancements covered all of tropical Southeast Asia and subtropical south China. They were due to photochemical ozone buildup from the biomass burning emissions from the Indonesian fires. The ozone-rich air mass was transported to Hong Kong following the east Asia local Hadley circulation and an abnormal anticyclonic flow related to the El Nino phenomenon in the tropical western Pacific. A rough estimation of the radiative forcing due to the ozone enhancement was carried out for two cases in October and December in 1997 using a normalized tropospheric ozone radiative forcing parameter derived from the Unified Chemistry-Climate model [Mickley et al., 1999]. The ozone enhancements induced an additional radiative forcing of 0.26 and 0.48 Wm−2 compared to the normal total forcing of 0.48 and 0.39 Wm−2 in October and December over the Hong Kong region. Estimation of the associated surface temperature change suggests that enhanced ozone from biomass burning on the scale of the 1997 Indonesian fires may have significant impact on regional surface temperature change.
The Sociological Determination: A Reflexive Look at Conducting Local Disaster Research after Hurricane Katrina

This paper examines the process of collecting data on New Orleanians affected by Hurricane Katrina. It does so by focusing upon the experiences of local researchers who were simultaneously conducting research on and within the disaster. It also documents one research team’s attempt to generate a random sample of residents from several New Orleans neighborhoods, stratified both by racial composition and level of damage. Further, it describes the challenges associated with navigating complex bureaucracies that are themselves affected by the disaster. Results demonstrate that our methods for drawing samples from six New Orleans neighborhoods yielded highly representative samples, even in heavily damaged neighborhoods where the long-term displacement required a multi-pronged strategy that involved contact by mail, telephone, and visits to local churches. The paper concludes by making recommendations for facilitating future research by locally affected researchers.
Microsatellite DNA polymorphism confirms reproductive isolation and reveals differences in population genetic structure of cryptic pipistrelle bat species

Previous studies have indicated that the common European pipistrelle bat ( Pipistrellus pipistrellus ) comprises two cryptic species, P. pipistrellus and Pipistrellus pygmaeus , which differ in echolocation call frequency and mitochon- drial DNA sequence. However, levels of divergence based on nuclear markers have not been examined, and hence the potential for male-mediated gene flow between the species cannot be discounted. Moreover, little is known about pop- ulation structure and migration patterns in either species. Here, we describe the use of microsatellites to investigate nuclear DNA differentiation between, and the pattern of population genetic structure within, the two cryptic pip- istrelle species. In total, 1300 individuals from 82 maternity colonies were sampled across the British Isles and Con- tinental Europe. We show, using multivariate analyses, that colonies of the same species are generally genetically more similar to each other than to those from the other species regardless of geographical location. Our findings sup- port the hypothesis that the species are reproductively isolated. Significant patterns of genetic isolation by distance were identified in both species, indicating that mating may occur before any long-distance autumnal migration. The presence of a sea channel does not confer higher levels of genetic differentiation among colonies over and above dis- tance alone in either species. Differences in genetic population structure were identified between the species, with P. pipistrellus showing a wider range of levels of genetic differentiation among colonies and a stronger relationship between genetic and geographical distance than P. pygmaeus . Differences in dispersal, mating behaviour, colony size and/or postglacial colonization patterns could contribute to the differences observed. © 2007 The Linnean Society of London, Biological Journal of the Linnean Society , 2007, 90 , 539-550.

A Study on the Effect of Ergonomics on Computer Operating OfficeWorkers in India

The effect of ergonomic factors have an influence on the productivity, health and wellbeing of office workers. Most of the office workers are working with computers. A study has been conducted for the benefit of millions of people working with computer. A subjective measurement was conducted through questionnaire survey from 70 office workers working with computers. These questionnaires were designed for the factors which are affecting the productivity and human health. The SPSS package was used to find the loading factor. Based on this analysis, all the factors are grouped under the four main ergonomic factors such as Physical, Environmental, Cognitive, Organizational ergonomics factor. Based on the Rotated component matrix these factors have been ranked as per the principal component analysis. The results revealed that the cognitive ergonomic factors and environmental ergonomic factors have more influence on productivity. Organization ergonomics and Physical ergonomics have less influence on office worker’s productivity. Cognitive ergonomic factors and environmental ergonomic factors have imperative role to play in the effectiveness of office workers when compared with physical and organizational ergonomic factors. The effect of cognitive factor is more than the environmental factors. The mental workload, memory lag, task difficulties, room temperature, illumination affects the productivity, health and wellbeing of workers in India.
Modelling the Relation Network in the Integrated Product and Design Process Model

The aim of this paper is to consider criteria for classifying the relations in engineering data structures. Some methods of modelling the network of relationships in the object-oriented environment are proposed. The network of relations is considered as established between objects which are instances of classes in the object-oriented design process and product model. In the presented approach, the relations between objects are also viewed as objects. An instance of such class represents binary or n-ary relation between instances of elementary classes. Having a class that represents the relation, the procedures of searching, retrieving and updating are easier to implement and maintain. The prototype of proposed system is developed in object database environment.
