Dirichlet Process Mixture Model For Document Clustering with Feature Extraction Which Helps In Page Ranking

To figure out the appropriate number of clusters to which documents should be partitioned is crucial task in document clustering. In this paper, we propose a novel approach, namely DPMFS, which does document clustering and it helps in improving page ranking. Here we are firstly grouping documents into a set of clusters whereas the number of document clusters is determined automatically by the Dirichlet process mixture model secondly identifying the discriminative words and separate them from irrelevant noise words. Our experiment shows that our proposed approach performs well on the synthetic dataset as well as real datasets. The comparison between our approach and some other stage of the art document clustering approach shows that our approach is more robust as well as effective for document clustering.

Performance Near Operational Boundaries

The performance of ELMy H-mode operation in ASDEX Upgrade and JET is compared. Special attention is paid to variations (usually reductions) in this performance near the operational limits which will need to be approached in a next-step device. In JET it is found that input powers substantially above the H-mode threshold power are required to obtain discharges with energy confinement enhancement factors at or above the usual ELMy H-mode scalings. Such a margin (as much as a factor of two in JET) is not observed in ASDEX Upgrade. It is proposed that this difference may be due to the higher edge collisionality in ASDEX and the results are compared to a recent theory based on interchange instabilities and magnetic flutter. In ASDEX Upgrade, the confinement in type I ELMy discharges degrades as the density is raised due to a stiffness of the temperature profiles which leads to a degradation of the core confinement. This type of stiffness is observed in JET only at relatively high edge densities. In JET, the edge confinement degrades as the density is increased by external gas fuelling, consistent with a constant edge pressure gradient and an edge barrier width which reduces in proportion to the edge ion poloidal Larmor radius. In both machines, H-mode performance is limited at high density by a transition first to the type III ELM regime and then to the L-mode. The confinement penalty, relative to good type I ELM discharges, of operating with type III ELMs is about 25-30%. The maximum densities for operation with type I or type III ELMs can be substantially increased by increasing the plasma triangularity in both machines.
Genetic relationships among collections of the Persian sturgeon , Acipenser persicus , in the south Caspian Sea detected by mitochondrial DNA – Restriction fragment length polymorphisms

In the present study, mitochondrial DNA polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay was used to assess the population structure and genetic relationships among six Persian sturgeon, Acipenser persicus populations from the south Caspian Sea along the Iranian coast. The complete nucleotide dehydrogenase subunit 5 (NADH 5) region of mtDNA amplified by PCR was digested with five restriction enzymes. In total, 154 individuals from six populations including: Guilan (Zone1-2), Mazandaran (Zone 3 and 5), Golestan (Zone 4) and Sefidroud River, from the south Caspian Sea along the Iranian coast were analyzed using five restriction endonucleases (Rsa І, Hinf І, HaeIII, Mbo І and Cfr13І), yielding 17 haplotypes. Samples from Sefidroud River were clearly identified by cluster and molecular variance model (AMOVA) analyses. This collection showed dominant haplotypes that were little in populations from the other geographic areas. The mean haplotype diversity (h) and nucleotide diversity (π) were 0.739±0.038 and 0.0105±0.0043, respectively. Based on heterogeneity test haplotype frequencies of Persian sturgeon populations and Monte-Carlo with 1000 replicates in PCR-RFLP method significant differences were seen (χ2 =37.12, P< 0.0001) and these results showed that haplotype distribution in different location were significant and populations of Sefidroud River were statistically significant (P< 0.0001). This result suggests that the unique genetic structure of Sefidroud River represents a highly valuable genetic resource and should now be treated as demographically independent and managed separately.
Fully Monolithic Photonic Integrated Circuits for Microwave and Millimeter Wave Signal Generation

We present two difierent photonic integrated circuits aimed to generate electrical signals within the microwave and millimeter wave range with two difierent techniques. The flrst approach uses the heterodyne technique, implementing a monolithic dual wavelength source by integrating on a single chip two distributed feedback (DFB) lasers together with the high speed photodiode. The second approach, using mode locked lasers, describes a novel device structure based on multimode interference re∞ectors (MIR).
Automatic extraction of quotes and topics from news feeds

The explosive growth in information production poses increasing challenges to consumers, confronted with problems often described as “information overflow”. We present verbatim, a software system that can be used as a personal information butler to help structure and filter information. We address a small part of the information landscape, namely quotes extraction from portuguese news. This problem includes several challenges, specifically in the areas of information extraction and topic distillation. We present a full description of the problems and our adopted approach. verbatim is available online at http://irlab.fe. up.pt/p/verbatim.
Role of Conservatism in Turkish Users' Instagram Behavior

The aim of this study is to classify Turkish Instagram users in terms of consumer behavior on social media and conservatism as a way of life. The data were collected via face-to-face survey method. 288 questionnaires were included in the analysis. Five point likert questions used for instagram and conservatism scale. Convenient sampling method is applied in selecting respondents. The sample consist of Instagram users over the age of 18 who lives in Istanbul. Based on cluster analysis results, two clusters were appropriate for this study. Cluster 1 consists of liberal individuals, who do not use Instagram for the purpose of sharing, and acting as opinion leader. However they are more tolerant towards woman rights, less religious and so on. On the other sides, individuals in Cluster 2 are more conservatives and less tolerant to sexual orientation and woman rights, however they can be defined as active users of instagram who are willing to share and obtain information from Instagram. This paper fulfils an identified need to study role of conservatism in using Instagram among Instagram users in Turkey.
A state of the art review of residential water demand modelling

The increased reliance on demand-side management policies as an urban water consumption management tool has stimulated considerable debate among economists, water utility managers, regulators, consumer interest groups and policymakers. In turn, this has fostered an increasing volume of literature aimed at providing best-practice estimates of price and income elasticities, quantifying the impact of non-price water restrictions and gauging the impact of nondiscretionary environmental factors affecting residential water demand. This paper provides a synoptic survey of empirical residential water demand analyses conducted in the last twenty-five years. Both model specification and estimation and the outcomes of the analyses are discussed.
Sub-cycle attosecond control in frustrated double ionization of molecules

We demonstrate sub-cycle control of frustrated double ionization (FDI) of the two-electron triatomic molecule D 3 + when driven by two orthogonally polarized two-color laser fields, where a weak mid-infrared laser field is employed to probe the FDI process triggered by a strong near-infrared laser field. We use a three-dimensional semi-classical model that fully accounts for the electron and nuclear motion in strong fields. We analyze the FDI probability and the distribution of the momentum of the escaping electron along the polarization direction of the mid-infrared laser field. These observables when considered in conjunction bear clear signatures of sub-cycle control of FDI. We find that the momentum distribution of the escaping electron has a striking hive-shape with features that can accurately be mapped to the time that one of the two electrons tunnel-ionizes at the start of the break-up process. This mapping distinguishes consecutive tunnel-ionization times within a cycle of the mid-infrared laser field but not tunnel-ionization times differing by an integer number of cycles.
A new focus in the science of networks: towards methods for design

In recent years, a realization that networks are ubiquitous in the natural and engineered worlds has led to a burgeoning interest in finding commonalities in their structures and dynamics. Here, we introduce a new design focus in this science of networks by proposing generic methods for synthesizing network controllers that exploit the topological structure. That is, we motivate a canonical controller synthesis problem for networks that has applications in such diverse areas as virus-spreading control and air traffic flow management. We address this design problem by using new techniques from decentralized control theory. Specifically, we mesh optimization machinery together with eigenvalue sensitivity and graph theory notions to identify general structural features of optimally actuated networks. From these features, we are in turn able to explicitly construct high-performance controllers, i.e. the ones that best exploit the network's topological structure. Our general approach for controller design is important because it both provides a broad insight into the structure of well-designed networks and contributes engineering solutions in numerous application areas (e.g. reduction in management delays and human-controller workload in air traffic systems).
The Myth of the Classic Hydrosere Model of Bog Succession

The classic hydrosere model of bog succession, which is still often cited and taught by ecologists, proposes that infilling of a shallow lake or pond by organic sediments produces a sequence of vegetation communities beginning with a marsh community of aquatic plants such as sedges, followed by a bog community composed mainly of Sphagnum mosses and various ericaceous shrubs, and culminating in a mature upland or mesic "climax" forest. A careful examination of the supporting literature indicates, however, that this model is based almost solely on observations of spatial zonation of vegetation around infilling water bodies. No studies can be found which contain clear quantitative evidence of successional pathways progressing from bog to upland forest. Indeed, numerous studies conclude that patterns of hydrosere succession are not consistent with the classic hydrosere model. Forest age structure, peat stratigraphy, and radiocarbon data presented from two bogs in Schefferville, Quebec, suggest that many bogs in this region, and elsewhere as indicated in the literature, are climax communities formed via both infilling of a water body (terrestrialization) and expansion of bogs into upland forests (paludification). An alternative model of hydrosere succession based on the bog climax hypothesis is presented.
Effective algorithm for building and solving linear systems

Several mesh-based techniques in computer graphics such as shape deformation, mesh editing, animation and simulation, build and solve linear systems. The most common method to build a linear system consists in traversing the topology (connectivity) of the mesh, producing in general a representation of the set of equations in form of a sparse matrix. Similarly, the solution of the system is achieved, by means of iterating over the set of equations in the default sequence of the vertices (unknowns). This paper presents a new algorithm, which optimizes the build of the linear system and its storage, and which allows the iteration over the set of equations in any arbitrary order. Additionally, our algorithm enables rapid modifications to the linear system, avoiding a complete rebuild.
Bootstrapping Extreme Value Statistics

In this thesis we investigate the use of bootstrapping schemes to estimate the variance of estimators from extreme value theory. We consider estimators for the extreme value index, the central parameter in extreme value theory, and extreme quantiles for two fundamental ap- proaches in extreme value theory. We analyse the Hill estimator for the extreme value index and the Weissman estimator for extreme quantiles from the peaks over threshold approach and the probability weighted moment estimators for the extreme value index and extreme quantiles from the block maxima approach. We find the limiting distributions of a boot- strapped sample and bootstrapped block maxima and subsequently determine the asymptotic behaviour of the bootstrapped Hill estimator and the bootstrapped probability weighted mo- ment estimators. For the latter estimators, we provide an heuristic argument to show that one may use the sample variance of bootstrapped estimators to estimate the variance of the initial estimator.
Antibacterial activity, cytotoxicity, antioxidant capacity and phytochemicals of Rheum australe rhizomes of Nepal

Rhizome of Rheum australe D. Don of Nepalese origin was evaluated for its antibacterial, cytotoxic and antioxidant efficacies. The plant extracts significantly inhibited the growth of Gram-positive and Gram-negative bacteria tested. Cytotoxicity of the methanolic and aqueous extracts was tested on the brine-shrimp nauplii and the LC50 value was determined to be 194.98 and 18.28 μg/ml, respectively. The aqueous extract contained a higher amount of total phenolics than the methanolic extract and the result was in correlation with their Fe (III) reducing power ability as well. However, the methanolic extract contained more potent DPPH free radical scavengers than the aqueous extract. Two anthraquinones namely chrysophanol and emodin were isolated from the hexane extract.
MODELING THE DYNAMIC BEHAVIOUR OF AXI-SYMMETRICAL FRUITS USING THE DISCRETE ELEMENT METHOD

A new Discrete Element (DE) method has been developed to model the dynamic behaviour of an assembly of axi-symmetrically shaped fruits. In the new method, which we term the “multi-element” method, model fruits (taken here to also include vegetables, grains and nuts) are comprised of overlapping spheres whose centres are fixed in position relative to each other along the major axis of symmetry of the fruit. Element spheres are inscribed in the real fruit shape such that the diameter of the spheres varies with the fruit surface contour. Contact detection between two neighbouring model fruits is achieved using standard DE methods for two single spheres. The method thus takes advantage of the speed and accuracy of contact detection associated with standard DE schemes employing single spheres. The scheme is well suited to numerical modelling of post-harvest operations such as hopper filling and emptying, conveying, sorting and object manipulation where the produce are discrete entities with relatively round smooth surfaces.
Protein Annotation & Advanced Insilico Based Mutation Hotspot Identification in Temperature Sensitive CDPK3 Protein of Oryza sativa

In the process of development of cold and heat tolerant rice varieties was done in field conditions. The current work is the extension of the same. In the current paper an extensive Insilico based research was carried out on the Mutational analysis and hot spot prediction of the protein CDPK3, Calcium Dependent Protein Kinases of Oriza Sativa. The work involves the retrieval of the protein sequence from the NCBI primary data base and identification of the Functional domains. Several sequences of the same protein from the other related plant species were collected and the phylogenetic study and the conservation prediction were performed. Tools like Protparam and SOPMA have been applied to analyze the Physico chemical parameters and the Structure prediction of the protein was carried out. The regions of disorder present in the protein sequence were identified using several tools including DISEMBL, GLOBPLOT, RONN etc. Based upon the results of RONN the major sites prone for mutations are identified. The effect of possible substitution mutations on the selected target site was analyzed. I mutant tool was employed to check the effect of all the substitution mutations on the stability of the protein sequence, PolyPhen was used to evaluate the effect of mutations on Functionality and the tolerance level is calculated using SIFT. The work concludes to provide the complete protein annotation of Cold
OVERVIEW OF PHOTOGRAMMETRIC MEASUREMENT TECHNIQUES IN MINIMALLY INVASIVE SURGERY USING ENDOSCOPES

Abstract. This contribution provides an overview of various photogrammetric measurement techniques in minimally invasive surgery and presents a self-developed prototypical trinocular endoscope for reliable surface measurements. Most of the presented techniques focus on applications regarding laparoscopy, which mean endoscopic operations in the abdominal or pelvic cavities. Since endoscopic operations are very demanding to the surgeon, various assistant systems have been developed. Imaging systems may use photogrammetric techniques in order to perform 3D measurements during operation. The intra-operatively acquired 3D data may be used for analysis, model registration, guidance or documentation. Passive and active techniques have been miniaturised, integrated into endoscopes and investigated by several research groups. The main advantages and disadvantages of several active and passive techniques adapted to laparoscopy are described in this contribution. Additionally, a self-developed trinocular endoscope is described and evaluated.
NONCAUSAL VECTOR AUTOREGRESSION

In this paper, we propose a new noncausal vector autoregressive (VAR) model for non-Gaussian time series. The assumption of non-Gaussianity is needed for reasons of identifiability. Assuming that the error distribution belongs to a fairly general class of elliptical distributions, we develop an asymptotic theory of maximum likelihood estimation and statistical inference. We argue that allowing for noncausality is of particular importance in economic applications that currently use only conventional causal VAR models. Indeed, if noncausality is incorrectly ignored, the use of a causal VAR model may yield suboptimal forecasts and misleading economic interpretations. Therefore, we propose a procedure for discriminating between causality and noncausality. The methods are illustrated with an application to interest rate data.
Low-Speed High-Lift Performance Improvements obtained and validated by the EC-project EPISTLE

A new method for low-drag high-lift system design based on viscous flow solvers was developed for Supersonic Commercial Transport wings within the EC research project EPISTLE. Two high-lift systems were manufactured for a large-scale wind tunnel model. The numerically predicted drag reductions (20% compared to a datum system) were fully confirmed by high Reynolds number tests. These drag reductions lower the low-speed noise for future SCT configurations by more than 4 EPNDB.
GENETIC DIVERSITY OF WILD ELEPHANT (Elephas maximus Linnaeus, 1758) IN THE NORTHEASTERN PART OF THAILAND

The phylogeography and genetic diversity of wild elephants in the northeastern part of Thailand was studied at Phuwua Wildlife Sanctuary (PW), Nong Khai Province; Dongyai Wildlife Sanctuary (DY), Buri Rum Province; Phuluang Wildlife Sanctuary (PL), Loei Province and Phukhieo Wildlife Sanctuary (PK), Chaiyaphum Province. The study was procedured from September 2009 through August 2010. The objectives were to investigate the levels of genetic diversity within populations of wild elephants in northeastern Thailand and also to study the evolutionary relationship among population clusters and with other areas within Thailand. PCR technique and base sequences from cytochrome b to the heading of control region in mitochondrial DNA were used. The results from 39, 57, 10, and 8 dung samples from PW, PK, PL and DY wildlife sanctuaries, respectively, showed 2 halplotypes (A and B) in PW, 2 haplotypes in PK (A and C), 2 haplotypes in PL (A and B), and only one haplotype in DY (A). Genetic analysis of the tip of cytochrome b to the base of the control region found variation at 27 sites of the 601 base pairs sampled which can be categorized into 3 haplotypes (AH, BQ, and NewB) for PW, 3 haplotypes (AH, NewA1, and BH) for PK, 3 haplotypes (AH, AB, and BO) for PL, and only 2 haplotypes (AH and AD) for DY. It can thus be concluded that there are 8 haplotypes of wild elephant genetic diversity and 2 population clusters, clade A and clade B. In Northeast Thailand, clade A was found more than clade B. The elephants in groups AB, AD, AH, and newA1 share more common traits than any other groups. Distinctively, elephants in group newB have a close relation with elephant group BO. AD is regarded as the ancestor of the other haplotypes.
Different Professionals' Interpretation of a Decoding Defi cit in Reading Skills

An educational profi le of a fi ctitious child with a decoding defi cit in reading skills was distributed by mail to audiology, speech-language pathology, and reading specialty professionals throughout the United States. Each participant was asked to review the profi le and complete a questionnaire. The survey asked open-ended questions concerning the professional’s interpretation of what may be the basis of the child’s learning diffi culties and the assessment tools needed for an evaluation. This study reviewed each professional’s analysis of the possible origin of the learning diffi culty and determined if a common response theme emerged from the different professional groups.
Examining the Transitional Impact of ICD-10 on Healthcare Fraud Detection

On October 1, 2015, the tenth revision of the International Classification of Diseases (ICD-10) will be mandatorily implemented in the United States. Although this medical classification system will allow healthcare professionals to code with greater accuracy, specificity, and detail, these codes will have a significant impact on the flavor of healthcare insurance claims. While the overall benefit of ICD-10 throughout the healthcare industry is unquestionable, some experts believe healthcare fraud detection and prevention could experience an initial drop in performance due to the implementation of ICD-10. We aim to quantitatively test the validity of this concern regarding an adverse transitional impact. This project explores how predictive fraud detection systems developed using ICD-9 claims data will initially react to the introduction of ICD-10. We have developed a basic fraud detection system incorporating both unsupervised and supervised learning methods in order to examine the potential fraudulence of both ICD-9 and ICD-10 claims in a predictive environment. Using this system, we are able to analyze the ability and performance of statistical methods trained using ICD-9 data to properly identify fraudulent ICD-10 claims. This research makes contributions to the domains of medical coding, healthcare informatics, and fraud detection.
