The ‘Copy and Paste’ Function, Patterns of Learner Activity and Enhancing Cognitive Tools

This research analyses video data to examine changes between levels of process of textbased content of learners using two versions of the ‘Copy and Paste’ function, an unmodified control version and an experimental version with an embedded interaction strategy designed to prompt learners to process more content effectively. Observed learner activity types were categorized as involving Low, Medium or High levels of cognitive processing and the pattern of learner switching between these levels is examined. The conclusions drawn from this analysis indicate that learners not only need mediating artifacts that prompt them to use appropriate processing strategies but that they also need to be made aware of; i) the level of cognitive processing in which they are engaged and ii) more importantly to be prompted to switch activities to those involving higher levels of cognitive processing when they have been conducting low level processing for extended periods.
Visual features extraction from variable scale images using early retina mechanisms

Most of robotic systems need visual outfits to interact with the envi- ronments. Since the arrival of humanoid robots with foveolar vision, and other mobile platforms with catadioptric sensors, variable scale imaging has became a major issue to work on biologically realistic data. In this aim, the use of visual neurosciences has been limited to early vision mechanisms of cortex areas and higher order features where the camera is seen as a simple acquisition tool. It seems that at the early stages of acquisition, the retina processes a dual coding action on images. This paper proposes a new bio-inspired method to extract infor- mation from foveolar images giving a model to the lateral inhibition mechanism of the retina. The presented model shows that using a redundant pyramidal ar- chitecture produces a coding effect of the image that reduces noise. In addition it provides an implicit coding of images: the reduced original image, the location of edges and eventually texture. Experimental results on real images are presented along with a scene recognition task showing the reliability of these features.
Competitiveness analysis of Czech agrarian foreign trade in the context of world agrarian market and agrarian trade of EU-27 countries

This paper analyses the commodity structure of Czech (CR) agrarian trade in relation to the EU countries. An emphasis is put on comparative advantages of particular aggregations from the view-point of their application on the EU internal market. This analysis is based on an evaluation of comparative advantages by means of a modified Balassa index. It is studied in two stages, for the internal EU market and the world market. The analysis results are then shown in a graph. Subsequently, the authors implement an idea arising from a BCG matrix on the results of the graphic presentation. The aim is to identify those aggregations (SITC, rev. 3) which are or have a potential to be a pillar of agri-business (ie, the “cash cows” and “stars”), and vice versa to show the aggregation which are non-prospective in the long term or problematic (ie, the “dogs” and “problem children”). As start are identified as those aggregations which are characterised by the highest growth rate of comparative advantage value. From the analysis results, changes are apparent if we compare the CR trade commodity structure in relation to the EU countries. Findings also concern the development of comparative advantages and following CR specialisation on trade with certain aggregations.
Image Resize Color Moments GLCM Build Index Feature Encryption Image Encryption Feature Extraction Query Index Feature Encryption

Accepted 02 Jul. 2017 Content-based search provides an important tool for users to consume the ever-growing digital media repositories. However, since communication between digital products takes place in a public network, the necessity of security for digital images becomes vital. Hence, the design of secure content-based image retrieval system is becoming an increasingly demanding task as never before. In this paper, the secure CBIR with additional improvement for the image retrieval has been presented. The proposed system consists of six phases briefly described as follows: first, feature extraction phase, which produces the low-level quantitative description of the image (color and texture) that used in calculation of similarity score and image indexing. Second, indexing for search process phase, hash table and bloom filter were employed for classification. Third, feature encryption phase, where content protection is performed using a method developed by us (including Chaotic Logistic Map). Fourth, image encryption phase, the chaos and stream cipher systems were applied as an image encryption system in order to achieve image security. Fifth, the retrieval phase, which provides a group of images replying the query based on the similarity score between images, calculated using the extracted features from each image. Finally, Relevance feedback phase, a technique that attempts to capture the user’s needs through iterative feedback. Although the system proved its efficiency in search performance (with 88% of average precision), security strength, and computational complexity, it does not mean the optimal system is designed, since some weakness points still can be found that are suggested to be improved as a future work.
Leading order integrability conditions for differential-difference equations

Abstract A necessary condition for the existence of conserved densities, ρ, and fluxes of a differential-difference equation which depend on q shifts, for q sufficiently large, is presented. This condition depends on the eigenvalues of the leading terms in the differential-difference equation. It also gives, explicitly, the leading integrability conditions on the density in terms of second derivatives of ρ.
Proficient Sharing of Personal Health Reportsin Cloud

A personal health report, or PHR, is a health report where health data and information cognate to the care of a patient is maintained by the patient. PHRs have the potential to avail analyze an individual’s health profile and identify health threats and amendment opportunities predicated on an analysis of drug interaction, current best medical practices, gaps in current medical care plans, and identification of medical errors. Hence it is an emerging patientcentric model of health information exchange, which is often outsourced to be stored at a third party, such as cloud providers. To have patients control it is very consequential to encrypt them afore outsourcing. The critical issues such as privacy, key management, flexible access and efficient utilizer revocation must be addressed. We utilize Attribute Predicated Encryption (ABE) to encrypt the PHR data, so that patients can sanction access not only by personal users, but withal sundry users from public domains with different professional roles, qualifications, and affiliationsthus enabling fine-grained and scalable data access control. The patient-centric framework provides a high degree of patient privacy by utilizing Attribute –Based Encryption techniques. The users in the PHR system are divided into multiple security domains that greatly reduce the key management intricacy for owners and users. This scheme additionally enables dynamic modification of access policies or files attributes, efficient on demand utilizer revocation and break glass access under emergency scenarios

Oro-Pharyngeal Carriage And Antimicrobial Susceptibility Of Streptococcus Pneumoniae From Healthy Children

Objectives: Streptococcus pneumoniae causes acute otitis media, pneumonia, meningitis and bacteraemia. This study aimed to determine the prevalence of Streptococcus pneumoniae oropharyngeal carriage in healthy children and the antimicrobial susceptibility in a daycare nursery and a government-managed orphanage in Kuala Lumpur during 2010.Methods: Throat swabs were obtained from 36 children of daycare nursery (open community) and from 84 orphans from orphanage (closed community) those did not receive any pneumococcal vaccine. Children were between births to 6 years of age. Antibiotic susceptibility of isolated strains was determined using disk diffusion method and Etest (minimum inhibitory concentration). Results: Overall prevalence of Streptococcus pneumoniae of the children was 1.7% (2 out of 120). Prevalence of the bacteria in open community was 5.6% (2 out of 36) and no positive cases were recorded in orphanage (closed community, (p=0.161). Prevalence was 15.4% (2 out of 13) in children aged below 2 years in the open community. There was no association was found to exist between Streptococcus pneumoniae carriage with age (p=0.432) and gender (p=0.418). Serotyping showed serotype 11F for one isolate, while the other was non-typable. Both isolates were susceptible to penicillin, azithromycin, ceftriaxone and vancomycin. The serotype 11F isolate was susceptible while the non-typable isolate was resistant to erythromycin.Conclusions: The results demonstrated low prevalence of Streptococcus pneumoniae in healthy children. These findings may complement other studies to explore further risk factors for colonisation, antimicrobial susceptibility and serotype distribution of Streptococcus pneumoniae to help for the planning of immunization strategies.
Interpreting Variation in Growth of Eurasian Spoonbill Chicks: Disentangling the Effects of Age, Sex and Environment

Chick body condition can be a sensitive indicator of local environmental conditions and has been shown to be correlated with chick survival. Designing a reliable index of chick body condition for a given species from a single measurement point requires knowledge about the extent of variation in body size, about chick age and about the relative sensitivity of the growth of different biometric measures to variation in environmental conditions. To gain this knowledge, we describe sex-specific variation in growth of several morphometric measures and body mass of Eurasian Spoonbills Platalea leucorodia. We repeatedly measured 35 chicks that grew up in small colonies on the island of Schiermonnikoog to derive detailed growth curves until fledging (based on the 12 surviving chicks) and to assess the extent of reduction in growth of starved chicks measured at least twice (n = 11) compared to those that survived. Growth curves until fledging were compared with biometric measurements of two to five week old chicks from (mostly) larger colonies of which hatching date was accurately estimated (n = 631). Growth of all measures, except the eighth primary, was sex-specific, with the most pronounced sex effect on the asymptotic values of tarsus length and body mass: adult males were predicted to become 17% heavier than females and to have 22% longer tarsi than females. Body mass and tarsus growth tended to be more reduced under food deprivation than (head-)bill and eighth primary growth. As an index of chick body condition, we propose to use the proportional deviation in body mass from the predicted body mass for a given age and sex. To do so, measurements of nearly fledged Spoonbill chicks should include at least eighth primary length to estimate age, tarsus length to estimate sex, and body mass as a measure that integrates age, sex and environmental effects.
Aluminium Tolerance Assessment of 141 Maize Germplasms in a Solution Culture

Aluminum (Al) toxicity usually occurs in acidic soils with a pH of 5.5 or lower. The selection and breeding of Al-tolerant cultivars is a useful approach for protecting maize from Al toxicity. Rapid and reliable screening methods must be developed to discriminate Al-tolerant and Al-sensitive maize genotypes. The relative root growth (RRG) of the longest root in a toxic Al solution was used to classify 141 maize germplasm lines into three groups with varied Al sensitivity: Al-sensitive, moderately Al-tolerant, and Al-tolerant. Among these lines, the cultivars HZ85 and 178 had the highest RRG values and therefore the highest Al tolerance. Further root assessment of six representative lines using other methods, such as digital imaging analysis of total root length and superficial area or volume, biomass measurement, and hematoxylin staining, was roughly consistent with the classification based on RRG. These results indicated that the RRG of the longest root could be used as a reliable and reproducible phenotypic index for the evaluation of Al tolerance in maize genotypes. Cultivars with different Al tolerances can be used to improve breeding and explore the mechanism of Al tolerance in maize.
News and Dollar Exchange Rate Dynamics

L'articolo descrive un modello GARCH multivariato, basato sulle news, dei tassi di cambio DM-$ e Yen-$, stimato simultaneamente con due variabili strettamente connesse con la loro dinamica: i tassi di interesse a lunga e l'indice azionario Dow Jones. Lo studio propone una frequenza di campionamento bigiornaliera (con osservazioni al termine della zona di trading Asiatica-Europea e della zona Americana) ed una nuova classe di news "unscheduled", che vengono usate accanto alle piu tradizionali news macroeconomiche, che sono tipicamente "scheduled". Le prime sono costituite da dichiarazioni delle autorita di politica economica, da eventi dei mercati dei cambi, da news di politica economica, da newsletter e commenti finanziari di varia natura, da tutti gli eventi piu importanti dei mercati finanziari mondiali. Le stime econometriche individuano distorsioni da simultaneita nelle stime GARCH univariate, in parte generate da variabili di news comuni a piu equazioni. La stima simultanea multivariata della media e della volatilita consente di attribuire un peso specifico a ciascuna classe di news nella spiegazione delle fluttuazioni dei cambi studiati, sia in media che in varianza. Le news "unscheduled" spiegano la maggior parte delle fluttuazioni dei cambi. Lo studio descrive anche una "gara" tra i modelli di news ed il "random walk" sulla "performance" previsiva e sulla profittabilita. I modelli di news battono il "random walk".
Study of Skin Friction in Channels by Lattice Boltzmann Method

A finite volume-lattice Boltzmann algorithm is applied to study skin friction behaviour in different channel flows. For this purpose, cell centred scheme is adapted to discretize the Boltzmann equation and consistent boundary conditions are also addressed, which resulted in a wider domain of stability. A simulation of flow in a two dimensional channels with different geometries are carried out. The results are compared with the valid previous results in which favourable agreement was observed. The results showed that skin friction in plane Poiseuille flow converged to 24/Re, but skin friction distribution in suddenly enlarged channels regain symmetry after some distance downstream of the expansion plane.
Applications du codage spatio-temporel à des réseaux sans fils

Les systemes de transmission non filaire sont tres populaires et se developpent rapidement. La demande est tres forte pour augmenter les debits ainsi que la qualite des liaisons alors que le maillage des reseaux se densifie. Dans ce contexte ou les ressources spectrales sont limitees, les codes espace-temps (ST) offrent de grandes possibilites d'evolution. Le codage ST permet d'augmenter le debit de transmission au niveau de la couche physique tout en relâchant les contraintes sur le compromis entre la puissance d'emission et le taux d'erreur de decodage. Dans la premiere partie de cette these, des techniques de codage et de decodage ST coherents ont ete appliquees a des reseaux locaux sans fils de type WIFI. Un demonstrateur MIMO 2x2 sur FPGA a ete realise a partir de la norme IEEE 802. 11A. La seconde partie traite du codage ST non coherent, ou les coefficients du canal sont inconnus au niveau de l'emetteur comme au niveau du recepteur. Une nouvelle famille de codes ST non coherents utilisant les modulations de frequence est proposee. Cette solution multi-antennaire permet, par exemple, d'ameliorer sensiblement les performances des systemes bluetooth.
A Proposed Solution to Secure MCC Uprising Issue and Challenges in the Domain of Cyber Security

The development of cloud computing and mobility,mobile cloud computing has emerged and become a focus of research. By the means of on-demand self-service and extendibility, it can offer the infrastructure, platform, and software services in a cloud to mobile users through the mobile network. Security and privacy are the key issues for mobile cloud computing applications, and still face some enormous challenges. In order to facilitate this emerging domain, we firstly in brief review the advantages and system model of mobile cloud computing, and then pay attention to the security and privacy in the mobile cloud computing. MCC provides a platform where mobile users make use of cloud services on mobile devices. The use of MCC minimizes the performance, compatibility, and lack of resources issues in mobile computing environment. By deeply analyzing the security and privacy issues from three aspects: mobile terminal, mobile network and cloud, we give the current security and privacy approaches. The users of MCC are still below expectations because of the associated risks in terms of security and privacy. These risks are playing important role by preventing the organizations to adopt MCC environment. Significant amount of research is in progress in order to reduce the security concerns but still a lot work has to be done to produce a security prone MCC environment. This paper presents a comprehensive literature review of MCC and its security issues,challenges and possible solutions for the security issues.

Screening of cloud microorganisms isolated at the puy de Dôme (France) station for the production of biosurfactants.

Abstract. A total of 480 microorganisms collected from 39 clouds sampled at the Puy de Dome station (alt. 1465 m; 45°46′19′′ N, 2°57′52′′ E; Massif Central, France) were isolated and identified. This unique collection was screened for biosurfactant (surfactants of microbial origin) production by measuring the surface tension (σ) of the crude extracts, comprising the supernatants of the pure cultures, using the pendant drop technique. The results showed that 41 % of the tested strains were active producers (σ
Overview of the GMES Sentinel-1 mission

In the framework of the EU/ESA co-funded Global Monitoring for Environment and Security (GMES) program, ESA is undertaking the development of the Sentinel-1 (S1) mission comprising a constellation of two satellites (A and B units) each carrying an imaging C-band SAR instrument. The objective of the S-1 mission is to acquire systematically and provide routinely data and information products for GMES and national services. The S-1 SAR instruments supports four exclusive imaging modes, namely the Interferometric Wide Swath (IW), the Extra Wide Swath (EW), the Strip-Map (SM), and the Wave (WV) mode. Both the IW and EW mode operate in TOPS (Terrain Observation with Progressive Scans in azimuth). The S-1 SAR system is designed to enable TOPS burst synchronization of repeat-pass datatakes supporting the generation of TOPS interferograms. In addition, the 12-day repeat orbit cycle of each satellite along with small orbital baselines will facilitate SAR interferometry (InSAR) applications. The paper provides an overview of the Sentinel-1 mission characteristics including the SAR instrument and its imaging modes, as well as discusses its SAR interferometry (InSAR) capability. Furthermore, the paper outlines the baseline mission operations strategy and commissioning phase activities.
