SYNTHESIS AND IMPLEMENTATION OF NiZnFe 2 O 4 FERRITES TO DESIGN EMBEDDED SYSTEM FOR HUMIDITY MEASUREMENT

2 ABSTRACT: Along with magnetic properties, the spinel ferrites exhibit promising electrical properties, deployment of which results into evolution of new area of applications as the electronic sensor materials. The electrical properties significantly depend upon the environmental compositions, for which it has been exposed. The electrical resistance of these sensor materials varies not only with gas concentration but also with change in water vapour concentration. With the view to develop an embedded technology based smart sensor module for humidity measurement a sensor material NixZn1-xFe2O4 are synthesized by chemical method and characterized by XRD and IR tools. The x-ray powder diffraction reveals the formation of single phase spinel ferrite, which is also supported by the IR absorption bands attributed to tetrahedral (A) site and octahedral (B) sites. Employing embedded philosophy, the sensor module is designed about AVR ATmega8L microcontroller for humidity measurement. The thick film of materials under investigation, prepared by screen painting technique, is used to sense the concentration of water molecules. Analog part of the system is wired about highly precise instrumentation amplifier AD620. Deployment of on-chip ADC of 10-bit resolution causes to increase in the preciseness of the results. The system is calibrated to the humidity in RH%. The data shown by the system under investigation reveals close match with the standard data.
Infinite Hidden Semantic Models for Learning with OWL DL

We propose a learning model for integrating OWL DL ontologies with statistical learning. In contrast to existing learning methods for the Semantic Web and approaches to the use of prior knowledge in machine learning, we allow for a semantically rich and fully formal representation of rules and constraints which enhance and control the learning task. In our implementation, we achieve this by combining a latent relational graphical model with description logic inference in a modular fashion. To demonstrate the feasibility of our approach we provide experiments with real world data accompanied by a set of SHOIN (D) axioms. The results illustrate two practical advancements: First, the probability of unknown roles of individuals can be inductively inferred without violating the constraints and second, known ABox axioms can be analyzed by means of clustering individuals per associated concept.

Automatic construction of parse trees for lexemes

Recently, Duband Feeley presented a technique that makes lexical analyzers able to build parse trees for the lexemes that match regu- lar expressions. While parse trees usually demonstrate how a word is generated by a context-free grammar, these parse trees demon- strate how a word is generated by a regular expression. This paper describes the adaptation and the implementation of that technique in a concrete lexical analyzer generator for Scheme. The adaptation of the technique includes extending it to the rich set of operators handled by the generator and reversing the direction of the parse trees construction so that it corresponds to the natural right-to- left construction of the lists in Scheme. The implementation of the adapted technique includes modifications to both the generation- time and the analysis-time parts of the generator. Uses of the new addition and empirical measurements of its cost are presented. Ex- tensions and alternatives to the technique are considered.
Practitioner review: short-term and working memory impairments in neurodevelopmental disorders: diagnosis and remedial support.

BACKGROUND This article provides an introduction to current models of working and short-term memory, their links with learning, and diagnosis of impairments. The memory impairments associated with a range of neurodevelopmental disorders (Down's syndrome, Williams syndrome, Specific Language Impairment, and attentional deficits) are discussed. METHODS Methods of alleviating the adverse consequences of working and short-term memory impairments for learning are identified. CONCLUSION Impairments of short-term and working memory are associated with learning difficulties that can be substantial, and that can be minimised by appropriate methods of remedial support.
F0 fluxbranes, F-walls and new braneworlds

We complete the list of fluxbrane solutions in classical supergravities by introducing Melvin-type spacetimes supported by antisymmetric forms of rank D − 1 and their pseudoscalar duals. In IIB theory, these solutions belong to the same family as the 7-brane and D-instanton. In current notation, a fluxbrane supported by the D − 1 form is an F0 brane, its Euclidean continuation is a cylindrical background which 'interacts' with a pointlike instanton. The general F0 brane can have a transverse space Sk × R(D−k−2) with 1 ≤ k ≤ D − 2. For k = 1 we find the complete solution containing four parameters, three of them associated with pointlike singularities on the Melvin-type background. The S-dual to the F0 brane in ten dimensions is the F8 fluxbrane of codimension one, or F-wall; similar fluxbranes exist in any dimension if an appropriate form field is present. F-walls contain naked singularities unless one introduces source branes. In such a way one obtains new braneworld-type solutions with two bulk scalar fields. Their relation to the supersymmetric braneworlds is discussed.
Supply Chain Management measurement and its influence on Operational Performance

This paper empirically confirmed a positive relationship between Supply Chain Management (SCM) and operational performance. A measurement model of the SCM construct was developed. Operational performance was conceptualized using competitive priorities literature with four dimensions: cost, quality, flexibility and delivery. Structural equation modeling was used to analyze a sample of 103 companies, in Brazil. Results showed positive effects of SCM on all performance dimensions, offering further support for the cumulative capabilities perspective. We also found evidence of an operational competence construct mediating the effect of SCM on performance, supported conceptually by the resource-based and relational views of strategy.
Cross Response of Slow Filters to Dual Pathogen Inoculation in ClosedHydroponic Growing Systems

The efficacy of slow filters for horticultural purposes is suggested to be the result of multiple factors. Physical and biological properties of the filter column and the nutrient solution are likely to influence on filter performance. It has previously been shown that enzyme activity on the filter skin is a main parameter which will explain roughly 50% of filter efficacy. Since enzyme activity is enhanced by the addition of fungal cell walls to the filter skin, presence of a fungal root pathogen might affect enzyme activity and filter efficacy. In this study, slow filters integrated into closed NFT systems with a tomato crop were inoculated with mycelia from Pythium aphanidermatum. Enzyme activity, microbial colonisation, polysaccharide content and DNA content of the filter skin as well as microbial flora and total organic carbon in the nutrient solution were monitored. Tests of filter efficacy against Fusarium oxysporum f.sp. cyclaminis showed no significant influence on filter efficacy by the addition of P. aphanidermatum. Enzyme activities in the filter skin were not affected by the addition of P. aphanidermatum. A negative correlation was found between biofilm polysaccharide content and activity of xylanase activity on the filter skin. Filter efficacy was high (>99.9%) throughout the study. No damage to the crop as effect of pathogenic fungi was seen. We concluded that abundance of an oomycete pathogen in a closed hydroponic system does not affect filter efficacy, and that the filter skin microflora function, but not composition, is affected by this pathogen.

Microarray Gene Expression and Stable Laws

In this work, the authors study the statistical distribution of microarray gene expression data. In particular, we give a brief review of literature pointing to the non-Gaussian features of gene expression data in the form of impulsiveness and asymmetry. We note that several previous publication note the Pareto tail behaviour in the data. We present a new model, namely the stable distribution to describe the observed statistical features of the data which is a subfamily of Pareto-tail distributions.
Crossed Wires: Interpreters, Translators, and Bilingual Workers in Cross-Language Research

Increasingly, researchers are undertaking studies involving people who do not speak the same language as they do. Sociologists have long argued that language constructs the social world at the same time as it describes it. However, the implications of this for cross-language research are rarely considered. Employing interpreters/translators and “cultural brokers” in research raises methodological issues around the meanings of concepts and how to convey difference. Using a project that employed two Asian mental health workers, the author teases out some of the implications for research of language difference. She focuses both on the value of a biographical approach and on the problems such an approach presents.
Genome rearrangements and pervasive meiotic drive cause hybrid infertility in fission yeast

Hybrid sterility is one of the earliest postzygotic isolating mechanisms to evolve between two recently diverged species. Here we identify causes underlying hybrid infertility of two recently diverged fission yeast species Schizosaccharomyces pombe and S. kambucha, which mate to form viable hybrid diploids that efficiently complete meiosis, but generate few viable gametes. We find that chromosomal rearrangements and related recombination defects are major but not sole causes of hybrid infertility. At least three distinct meiotic drive alleles, one on each S. kambucha chromosome, independently contribute to hybrid infertility by causing nonrandom spore death. Two of these driving loci are linked by a chromosomal translocation and thus constitute a novel type of paired meiotic drive complex. Our study reveals how quickly multiple barriers to fertility can arise. In addition, it provides further support for models in which genetic conflicts, such as those caused by meiotic drive alleles, can drive speciation. DOI: http://dx.doi. org/10.7554/eLife.02630. 001
Teaching and Training Cybersecurity as a Cloud Service

The explosive growth of IT infrastructures, cloud systems, and Internet of Things (IoT) have resulted in complex systems that are extremely difficult to secure and protect against cyberattacks which are growing exponentially in complexity and in number. Overcoming the cybersecurity challenges is even more complicated due to the lack of training and widely available cybersecurity environments to experiment with and evaluate new cybersecurity methods. The goal of our research is to address these challenges by exploiting cloud services. In this paper, we present the design, analysis, and evaluation of a cloud service that we refer to as Cybersecurity Lab as a Service (CLaaS) which offers virtual cybersecurity experiments that can be accessed from anywhere and from any device (desktop, laptop, tablet, smart mobile device, etc.) with Internet connectivity. In CLaaS, we exploit cloud computing systems and virtualization technologies to provide virtual cybersecurity experiments and hands-on experiences on how vulnerabilities are exploited to launch cyberattacks, how they can be removed, and how cyber resources and services can be hardened or better protected. We also present our experimental results and evaluation of CLaaS virtual cybersecurity experiments that have been used by graduate students taking our cybersecurity class as well as by high school students participating in GenCyber camps.
Co-regulation of two gene activities by tetracycline via a bidirectional promoter.

Recently, we have described a regulatory system that allows the stringent control of individual gene activities in higher eukaryotic cell lines (1), in plants (2) and in animals (3,4). The essential components of this system are (i) an RNA polymerase II minimal promoter placed downstream of multiple operator sequences (tetO) of the Escherichia coli TnlO tetracycline resistance operon and (ii) a fusion between the Tet repressor (TetR) and the herpes simplex virus protein 16 (VP16), named tTA (1). In the absence of tetracycline (Tc), tTA binds to the tet operators to activate transcription from the minimal promoter, whereas in the presence of Tc its association and consequently its transcription activation is prevented. After the binding of tTA, minimal promoters derived from the cytomegalovirus IE promoter (PhCMv; 5) and fused to seven tetO sequences reach the remarkable strength of the parent promoter in HeLa cells when compared in transient expression assays (6). This high activation potential of tTA and the arrangement of its binding sites within PhCMV*-i [(! )'»see Fig. 1A] suggested the design of a bidirectional promoter which would allow the simultaneous regulation of two transcriptional units from centrally located multiple tetO sequences (Fig. 1A). Such a promoter should be useful for a number of experimental approaches. First, it may allow the co-regulation of the synthesis of two gene products in stoichiometric amounts, frequently a prerequisite for the production of heterodimeric (or hetero-oligomeric) proteins. Second, by fusing minimal promoters of differing efficiencies to the centrally located tetO sequences, two gene products may be co-regulated at different but defined levels. Third, by integrating an appropriate reporter gene at one side of the bidirectional promoter, the regulation of a not-readily-assayable gene of interest may be monitored via the reporter function. This latter possibility may also facilitate—at the cellular as well as at the organismal level—the screening for properly integrated expression units controlling the gene of interest.
Inversion of Dopamine Responses in Striatal Medium Spiny Neurons and Involuntary Movements

Dopamine influence in the striatum is essential to motor behavior and may lead to involuntary movements in pathologic conditions. The basic mechanisms lie in differential dopamine responses of medium spiny neurons (MSNs) contributing to striatal output pathways. The relationship between striatal discharge and mobility is thus critical to understanding the actions of dopamine. Using extracellular recordings in severely parkinsonian monkeys, we examined the activity changes of MSNs during different levels of dopamine stimulation. The activity of single MSNs was recorded continuously throughout conditions of parkinsonian disability, its reversal, and the exhibition of involuntary movements after levodopa administration. Parkinsonian disability was associated with robust and widely distributed increases of MSN firing. In the parkinsonian state, dopamine influx produced both increases and decreases in the discharge rate of MSNs. Furthermore, in contrast to the expected net reduction of activity, dopamine-induced recovery of mobility occurred with predominant further increases of neuronal activity. In contrast, involuntary movements were associated with a distinctive inversion of the dopamine responses. The activity increases and decreases associated with the recovery of mobility were subsequently inverted in a number of neurons, and these bidirectional changes created large differences of discharge across MSNs. Thus, a markedly dysregulated state of striatal activity develops after chronic dopamine denervation and, in such a state of MSN activity, dopamine induces altered and disproportionate responses. These findings point to the fundamental role of dopamine-mediated balance of striatal outputs for normal movement.
Asesmen Portofolio dalam Pembelajaran IPA di Sekolah Dasar

The importance of a scoring system that can measure students' abilities cognitively, affectively and psychomotorically requires an assessment that can measure student learning outcomes that can not only be measured by value through written tests, so that the quality of learning can grow better then a portfolio assessment is required Part of the classroom assessment currently under development. A portfolio is a collection of students' work that requires context-specific performance, as for examples of what students can include in the portfolio are tests, evaluated work for compulsory student tasks, performance tasks, and work projects such as papers or Other tasks created by the students themselves. By applying an alternative assessment that is one of the assessment of the portfolio of students, can be collected evidence of student progress that can actually be used as a consideration to improve the next learning process.In addition, such assessment is felt more just and transparent for students and can increase student motivation To be actively involved in the learning process.
Run-Time Management of Dynamically Recon gurable Designs

A method for managing recon gurable designs, which supports run-time con guration transformation, is proposed. This method involves structuring the recon guration manager into three components: a monitor, a loader, and a con guration store. Di erent trade-o s can be achieved in con guration time, optimality of the con gured circuits, and the complexity of the recon guration manager, depending on the reconguration methods and the amount of run-time information available at compile time. The proposed techniques, implementable in hardware or software, are supported by our tools and can be applied to both partially and non-partially recon gurable devices. We describe the combined and the partitioned recon guration methods, and use them to illustrate the techniques and the associated trade-o s.
Disability and transitions from education to work

This paper outlines the changing employment climate and shift in attitudes towards disabled people who are expected to become economically active in order to fulfil their role as responsible citizens. We briefly describe the employment profile of disabled people and reiterate the combination of factors identified in shaping progression into the workforce. We provide a summary of two research projects, the Disability Effective Inclusive Policies (DEIP) funded by European Social Fund with a clear connection to EU equity and employability agenda, and the Lancashire Aimhigher Disability (LAD) project designed to support the government's aim of widening participation. We discuss aspects of the transition process, drawing explicitly on interviews with disabled people, policy makers and practitioners involved in developing or implementing policy and providing support services designed to aid the transition process. We conclude that there is a continuing need for a focus on the concept of transition in policy and practice.
CURVATURE-INDUCED BOUND STATES IN QUANTUM WAVEGUIDES IN TWO AND THREE DIMENSIONS

Dirichlet Laplacian on curved tubes of a constant cross section in two and three dimensions is investigated. It is shown that if the tube is non-straight and its curvature vanishes asymptotically, there is always a bound state below the bottom of the essential spectrum. An upper bound to the number of these bound states in thin tubes is derived. Furthermore, if the tube is only slightly bent, there is just one bound state; we derive its behaviour with respect to the bending angle. Finally, perturbation theory of these eigenvalues in any thin tube with respect to the tube radius is constructed and some open questions are formulated.
I-vectors and ILP clustering adapted to cross-show speaker diarization

We propose to study speaker diarization from a collection of audio documents. The goal is to detect speakers appearing in several shows. In our approach, each show of the collection is processed separately before being processed collectively , to group speakers involved in several shows. Two clustering methods are studied for the overall processing of the collection: one uses the NCLR metric and the other is inspired by techniques based on i-vectors, mainly used in the speaker verification field. Both methods were evaluated on the whole training corpus of ESTER 2. The method based on the use of i-vectors achieves error rates similar to those obtained by the NCLR method, however, the computation time is on average 8.66 times faster. Therefore, this method is suitable for processing large volumes of data.
Fidelity in sensory integration intervention research.

OBJECTIVE We sought to assess validity of sensory integration outcomes research in relation to fidelity (faithfulness of intervention to underlying therapeutic principles). METHOD We identified core sensory integration intervention elements through expert review and nominal group process. Elements were classified into structural (e.g., equipment used, therapist training) and therapeutic process categories. We analyzed 34 sensory integration intervention studies for consistency of intervention descriptions with these elements. RESULTS Most studies described structural elements related to therapeutic equipment and interveners' profession. Of the 10 process elements, only 1 (presentation of sensory opportunities) was addressed in all studies. Most studies described fewer than half of the process elements. Intervention descriptions in 35% of the studies were inconsistent with one process element, therapist-child collaboration. CONCLUSION Validity of sensory integration outcomes studies is threatened by weak fidelity in regard to therapeutic process. Inferences regarding sensory integration effectiveness cannot be drawn with confidence until fidelity is adequately addressed in outcomes research.
A Stratified Approach for Camera Calibration Using Spheres

This paper proposes a stratified approach for camera calibration using spheres. Previous works have exploited epipolar tangents to locate frontier points on spheres for estimating the epipolar geometry. It is shown in this paper that other than the frontier points, two additional point features can be obtained by considering the bitangent envelopes of a pair of spheres. A simple method for locating the images of such point features and the sphere centers is presented. An algorithm for recovering the fundamental matrix in a plane plus parallax representation using these recovered image points and the epipolar tangents from three spheres is developed. A new formulation of the absolute dual quadric as a cone tangent to a dual sphere with the plane at infinity being its vertex is derived. This allows the recovery of the absolute dual quadric, which is used to upgrade the weak calibration to a full calibration. Experimental results on both synthetic and real data are presented, which demonstrate the feasibility and the high precision achieved by our proposed algorithm.
