Sample records for browse search quick

  1. Book Shelf virtual browse interface and searching for records with physical copies on CDS

    CERN Document Server

    Amanor, Christopher

    2013-01-01

    This project provided the opportunity to learn how the CERN Document Server functions by creating a local invenio instance. With the python programming language, a feature was implemented on CDS in conjunction with other developers. This feature makes it possible for CDS users to search for records using their shelf number and for records which have a physical copy attached to them. This was done by adding the fields 852__2, 852__h and 340__p, obtained from a bibicirculation module’s database table to the marc data of the records. Research was also done into ways of creating a virtual browsing system for CDS users to quickly browse through shelves of books while online.

    WANG, LU; Heck, Larry; Hakkani-Tur, Dilek

    2016-01-01

    Training statistical dialog models in spoken dialog systems (SDS) requires large amounts of annotated data. The lack of scalable methods for data mining and annotation poses a significant hurdle for state-of-the-art statistical dialog managers. This paper presents an approach that directly leverage billions of web search and browse sessions to overcome this hurdle. The key insight is that task completion through web search and browse sessions is (a) predictable and (b) generalizes to spoken d...

    Full Text Available An improved user profile based on the user browsing behavior is proposed in this study. In the user profile, the user browsing web pages behaviors, the level of interest to keywords, the user's short-term interest and long-term interest are overall taken into account. The improved user profile based on the user browsing behavior is embedded in the personalized search engine system. The basic framework and the basic functional modules of the system are described detailed in this study. A demonstration system of IUBPSES is developed in the .NET platform. The results of the simulation experiments indicate that the retrieval effects which use the IUBPSES based on the improved user profile for information search surpass the current mainstream search engines. The direction of improvement and further research is proposed in the finally.

  6. Search the Audio, Browse the Video—A Generic Paradigm for Video Collections

    2003-01-01

    Full Text Available The amount of digital video being shot, captured, and stored is growing at a rate faster than ever before. The large amount of stored video is not penetrable without efficient video indexing, retrieval, and browsing technology. Most prior work in the field can be roughly categorized into two classes. One class is based on image processing techniques, often called content-based image and video retrieval, in which video frames are indexed and searched for visual content. The other class is based on spoken document retrieval, which relies on automatic speech recognition and text queries. Both approaches have major limitations. In the first approach, semantic queries pose a great challenge, while the second, speech-based approach, does not support efficient video browsing. This paper describes a system where speech is used for efficient searching and visual data for efficient browsing, a combination that takes advantage of both approaches. A fully automatic indexing and retrieval system has been developed and tested. Automated speech recognition and phonetic speech indexing support text-to-speech queries. New browsable views are generated from the original video. A special synchronized browser allows instantaneous, context-preserving switching from one view to another. The system was successfully used to produce searchable-browsable video proceedings for three local conferences.

  7. The browse file of NASA/JPL quick-look radar images from the Loch Linnhe 1989 experiment

    Brown, Walter E., Jr. (Editor)

    1989-01-01

    The Jet Propulsion Laboratory (JPL) Aircraft Synthetic Aperture Radar (AIRSAR) was deployed to Scotland to obtain radar imagery of ship wakes generated in Loch Linnhe. These observations were part of a joint US and UK experiment to study the internal waves generated by ships under partially controlled conditions. The AIRSAR was mounted on the NASA-Ames DC-8 aircraft. The data acquisition sequence consisted of 8 flights, each about 6 hours in duration, wherein 24 observations of the instrumented site were made on each flight. This Browse File provides the experimenters with a reference of the real time imagery (approximately 100 images) obtained on the 38-deg track. These radar images are copies of those obtained at the time of observation and show the general geometry of the ship wake features. To speed up processing during this flight, the images were all processed around zero Doppler, and thus azimuth ambiguities often occur when the drift angel (yaw) exceeded a few degrees. However, even with the various shortcomings, it is believed that the experimenter will find the Browse File useful in establishing a basis for further investigations.

  8. How happy is your web browsing? A model to quantify satisfaction of an Internet user searching for desired information

    Science.gov (United States)

    Banerji, Anirban; Magarkar, Aniket

    2012-09-01

    We feel happy when web browsing operations provide us with necessary information; otherwise, we feel bitter. How to measure this happiness (or bitterness)? How does the profile of happiness grow and decay during the course of web browsing? We propose a probabilistic framework that models the evolution of user satisfaction, on top of his/her continuous frustration at not finding the required information. It is found that the cumulative satisfaction profile of a web-searching individual can be modeled effectively as the sum of a random number of random terms, where each term is a mutually independent random variable, originating from ‘memoryless’ Poisson flow. Evolution of satisfaction over the entire time interval of a user’s browsing was modeled using auto-correlation analysis. A utilitarian marker, a magnitude of greater than unity of which describes happy web-searching operations, and an empirical limit that connects user’s satisfaction with his frustration level-are proposed too. The presence of pertinent information in the very first page of a website and magnitude of the decay parameter of user satisfaction (frustration, irritation etc.) are found to be two key aspects that dominate the web user’s psychology. The proposed model employed different combinations of decay parameter, searching time and number of helpful websites. The obtained results are found to match the results from three real-life case studies.

  9. How to do a quick search for evidence.

    Science.gov (United States)

    Isaacs, David

    2014-08-01

    Doctors quote lack of time and lack of knowledge as major obstacles to searching the literature for evidence. This article argues that it is possible to do a literature search in 10-15 minutes with little specialist knowledge, using the Clinical Queries option of Medline (PubMed). PubMed is a free, user friendly service available to anyone with access to the internet and designed by librarians for use by clinicians who are not skilled in electronic searching. Numerous hidden search filters built into Clinical Queries facilitate targeted searches and find all published systematic reviews (including Cochrane Reviews). If no systematic reviews are available, the clinician can find randomised controlled trials and observational studies. PMID:24612231

    Similarity search technique has been proved to be an effective way for retrieving multimedia content. However, as the amount of available multimedia data increases, the cost of developing from scratch a robust and scalable system with content-based image retrieval facilities is quite prohibitive. In this paper, we propose to exploit an approach that allows us to convert low level features into a textual form. In this way, we are able to easily set up a retrieval system on top of the Lucene se...

    2010-01-01

    Searching is a fundamental task to support research. Current search engines are keyword-based. Semantic technologies promise a next generation of semantic search engines, which will be able to answer questions. Current approaches either apply natural language processing to unstructured text or they assume the existence of structured statements over which they can reason. This work provides a system for combining the classical keyword-based search engines with semantic annotation. Conventi...

  14. Searching the databases: a quick look at Amazon and two other online catalogues.

    Science.gov (United States)

    Potts, Hilary

    2003-01-01

    The Amazon Online Catalogue was compared with the Library of Congress Catalogue and the British Library Catalogue, both also available online, by searching on both neutral (Gay, Lesbian, Homosexual) and pejorative (Perversion, Sex Crime) subject terms, and also by searches using Boolean logic in an attempt to identify Lesbian Fiction items and religion-based anti-gay material. Amazon was much more likely to be the first port of call for non-academic enquiries. Although excluding much material necessary for academic research, it carried more information about the individual books and less historical homophobic baggage in its terminology than the great national catalogues. Its back catalogue of second-hand books outnumbered those in print. Current attitudes may partially be gauged by the relative numbers of titles published under each heading--e.g., there may be an inverse relationship between concern about child sex abuse and homophobia, more noticeable in U.S. because of the activities of the religious right.

  15. The science of searching--how to find the evidence quickly and efficiently.

    LENUS (Irish Health Repository)

    Wallace, J

    2012-04-01

    One of the most common findings from health research is the failure to routinely translate research evidence into daily practice. Studies simply can\\'t guarantee the use of their findings. There is just too much research to keep track of and so a large gap develops between what is known and what is done. Evidence that should change practice is often ignored for years. The literature is constantly changing and when an answer to a clinical question is sought, it often comes from an out-of-date textbook. Remaining knowledgeable of current, relevant research is difficult. Consequently, the development of skills in searching electronic databases is vital for the up-to-date clinician.

    Full Text Available This paper advocates a novel approach for mobile web browsing based on cooperation among wireless devices within close proximity operating in a cellular environment. In the actual state of the art, mobile phones can access the web using different cellular technologies. However, the supported data rates are not sufficient to cope with the ever increasing traffic requirements resulting from advanced and rich content services. Extending the state of the art, higher data rates can only be achieved by increasing complexity, cost, and energy consumption of mobile phones. In contrast to the linear extension of current technology, we propose a novel architecture where mobile phones are grouped together in clusters, using a short-range communication such as Bluetooth, sharing, and accumulating their cellular capacity. The accumulated data rate resulting from collaborative interactions over short-range links can then be used for cooperative mobile web browsing. By implementing the cooperative web browsing on commercial mobile phones, it will be shown that better performance is achieved in terms of increased data rate and therefore reduced access times, resulting in a significantly enhanced web browsing user experience on mobile phones.

    Full Text Available In today’s high tech environment every organization, individual computer users use internet for accessing web data. To maintain high confidentiality and security of the data secure web solutions are required. In this paper we described dedicated anonymous web browsing solutions which makes our browsing faster and secure. Web application which play important role for transferring our secret information including like email need more and more security concerns. This paper also describes that how we can choose safe web hosting solutions and what the main functions are which provides more security over server data. With the browser security network security is also important which can be implemented using cryptography solutions, VPN and by implementing firewalls on the network. Hackers always try to steal our identity and data, they track our activities using the network application software’s and do harmful activities. So in this paper we described that how we can monitor them from security purposes.

    Full Text Available Abstract Background Seqcrawler takes its roots in software like SRS or Lucegene. It provides an indexing platform to ease the search of data and meta-data in biological banks and it can scale to face the current flow of data. While many biological bank search tools are available on the Internet, mainly provided by large organizations to search their data, there is a lack of free and open source solutions to browse one’s own set of data with a flexible query system and able to scale from a single computer to a cloud system. A personal index platform will help labs and bioinformaticians to search their meta-data but also to build a larger information system with custom subsets of data. Results The software is scalable from a single computer to a cloud-based infrastructure. It has been successfully tested in a private cloud with 3 index shards (pieces of index hosting ~400 millions of sequence information (whole GenBank, UniProt, PDB and others for a total size of 600 GB in a fault tolerant architecture (high-availability. It has also been successfully integrated with software to add extra meta-data from blast results to enhance users’ result analysis. Conclusions Seqcrawler provides a complete open source search and store solution for labs or platforms needing to manage large amount of data/meta-data with a flexible and customizable web interface. All components (search engine, visualization and data storage, though independent, share a common and coherent data system that can be queried with a simple HTTP interface. The solution scales easily and can also provide a high availability infrastructure.

  5. Hyperdatabase: A schema for browsing multiple databases

    International Nuclear Information System (INIS)

    In order to insure effective information retrieval, a user may need to search multiple databases on multiple systems. Although front end systems have been developed to assist the user in accessing different systems, they access one retrieval system at a time and the search has to be repeated for each required database on each retrieval system. More importantly, the user interacts with the results as independent sessions. This paper models multiple bibliographic databases distributed over one or more retrieval systems as a hyperdatabase, i.e., a single virtual database. The hyperdatabase is viewed as a hypergraph in which each node represents a bibliographic item and the links among nodes represent relations among the items. In the response to a query, bibliographic items are extracted from the hyperdatabase and linked together to form a transient hypergraph. This hypergraph is transient in the sense that it is ''created'' in response to a query and only ''exists'' for the duration of the query session. A hypertext interface permits the user to browse the transient hypergraph in a nonlinear manner. The technology to implement a system based on this model is available now, consisting of powerful workstation, distributed processing, high-speed communications, and CD-ROMs. As the technology advances and costs decrease such systems should be generally available.

    2016-01-01

    Reconciling the well known benefits of shrubs for forage with environmental goals, whilst preventing their dominance, is a major challenge in rangeland management. Browsing may be an economical solution for shrubby rangelands as herbivore browsing has been shown to control juvenile shrub growth. Less convincing results have been obtained for adult plants, and long-term experiments are required to investigate the cumulative effects on adult plants. We therefore assessed the impact of different levels of browsing intensity on key demographic parameters for a major dominant shrub species (broom, Cytisus scoparius), focusing on adult plants. We assigned individual broom plants to one of three age classes: 3-5 years (young adults); 5-7 years (adults); and 7-9 years (mature adults). These plants were then left untouched or had 50% or 90% of their total edible stem biomass removed in simulated low-intensity and high-intensity browsing treatments, respectively. Morphological, survival and fecundity data were collected over a period of four years. Browsing affected the morphology of individual plants, promoting changes in subsequent regrowth, and decreasing seed production. The heavily browsed plants were 17% shorter, 32% narrower, and their twigs were 28% shorter. Light browsing seemed to control the growth of young adult plants more effectively than that of older plants. Reproductive output was considerably lower than for control plants after light browsing, and almost 100% lower after heavy browsing. High-intensity browsing had a major effect on survival causing high levels of plant mortality. We conclude that suitable browsing practices could be used to modify adult shrub demography in the management of shrub dominance and forage value.

    2012-01-01

    Purpose: This study attempts to investigate how a user’s search behavior changes in the exploratory search process in order to understand the characteristics of the user’s search behavior and build a behavioral model.Design/methodology/approach: Forty-two matriculated full-time senior college students with a female-to-male ratio of 1 to 1 who majored in medical science in Jilin University participated in our experiment. The task of the experiment was to search for information about "the influence of environmental pollution on daily life" in order to write a report about this topic. The research methods include concept map, query log analysis and questionnaire survey.Findings: The results indicate that exploratory search can significantly change the knowledge structure of searchers. As searchers were moving through different stages of the exploratory search process, they experienced cognitive changes, and their search behaviors were characterized by quick browsing, careful browsing and focused searching.Research limitations: The study used only one search topic, and there is no comparision or control group. Although we took search habits, personal thinking habits, personality characteristics and professional background into account, a more detailed study to analyze the effects of these factors on exploratory search behavior is needed in our further research.Practical implications: This study can serve as a reference for other researchers engaged in the same effort to construct the supporting system of exploratory search.Originality/value: Three methods are used to investigate the behavior characteristics during exploratory search.

    2003-11-01

    The huge amount of multimedia data produced worldwide requires annotation in order to enable universal content access and to provide content-based search-and-retrieval functionalities. Since manual video annotation can be time consuming, automatic annotation systems are required. We review recent approaches to content-based indexing and annotation of videos for different kind of sports and describe our approach to automatic annotation of equestrian sports videos. We especially concentrate on MPEG-7 based feature extraction and content description, where we apply different visual descriptors for cut detection. Further, we extract the temporal positions of single obstacles on the course by analyzing MPEG-7 edge information. Having determined single shot positions as well as the visual highlights, the information is jointly stored with meta-textual information in an MPEG-7 description scheme. Based on this information, we generate content summaries which can be utilized in a user-interface in order to provide content-based access to the video stream, but further for media browsing on a streaming server.

    Intake rates by large herbivores are governed by among other things plant traits. We used Masai giraffe (Giraffa camelopardalis tippelskirchi Matschie) as study animals, testing whether they as very large browsers would follow the Jarman-Bell principle and maximize intake rate while tolerating low forage quality. We worked in Arusha National Park, Tanzania. We investigated how intake rate was determined by bite mass and bite rate, and show that bite mass and bite rate were determined by plant characteristics, governed by inherent plant traits, plant traits acquired from previous years' browsing, and season. We predicted that; (1) bite mass would be larger in trees without spines than with (2) bite mass would be larger in the wet season than in the dry, (3) bite rate would be higher in spinescent trees than in non-spinescent, (4) bite rate and/or bite mass would increase with previous years' browsing, (5) bite mass, bite rate or browsing time per tree would be highest for high trees with large, although still available canopies. Visual observations were used to collect data on tree attributes, number of bites taken and time of browsing. Sample size was 132 observed giraffe. We found that bite mass was larger in spineless than in spinescent trees and was larger in the wet season than in the dry. Bite rate, but not bite mass, increased with increasing browsing in previous years and was highest on two to three meter high trees and in spinescent trees. Intake rate followed bite mass more than bite rate and was higher in spineless than in spinescent trees, higher in the wet season than in the dry, and tended to increase with tree height. Giraffe did not prioritize the highest intake rate, but browsed much on Acacias giving a high quality diet but a low intake rate.

    2000-12-01

    Full Text Available Browsing as an important part of human information behavior has been observed and investigated in the context of information seeking in the library in general and has assumed greater importance in human-machine interaction in particular. However, the nature and consequences of browsing are not well understood, and little is known of the success rate of such behavior.In this research, exploratory empirical case studies from three types of libraries were conducted, using questionnaires, observation logs, interviews, and computer search logs, to derive the empirical evidence to understand, from the user point of view, what are the consequences of browsing, what constitutes successful browsing, and what factors influence the extent of browsing. Content analysis and statistical analysis were conducted to analyze and synthesize the data. The research results show: (1 There are nine categories of the consequence of browsing, including accidental findings, modification of information need, found the desirable information, learning, feeling relaxation/recreational, information gathering, keeping updated, satisfying curiosity, and not finding what is needed. (2 Four factors that produce successful browsing: intention, the amount or quality of information, the utility of what is found, and help for solving problem or making judgment. (3 Three types of reasons for unsuccessful experience in browsing: not finding what one wanted, inadequate volume or quality of information, and not finding some things useful or interesting. (4 Three types of reasons for partial success: found the intended object but not happy with the quality or amount of information in it, not finding what one wanted but discovering new or potential useful information, not accomplish one purpose but achieve another one given multiple purposes. (5 The influential factors that affect the extent one engages in browsing include browser’s time, scheme of information organization, proximity to

  8. A Quaternary-Stage User Interest Model Based on User Browsing Behavior and Web Page Classification

    Zongli Jiang; Hang Su

    2012-01-01

    The key to personalized search engine lies in user model. Traditional personalized model results in that the search results of secondary search are partial to the long-term interests, besides, forgetting to the long-term interests disenables effective recollection of user interests. This paper presents a quaternary-stage user interest model based on user browsing behavior and web page classification, which consults the principles of cache and recycle bin in operating system, by setting up an illuminating text-stage and a recycle bin interest-stage in front and rear of the traditional interest model respectively to constitute the quaternary-stage user interest model. The model can better reflect the user interests, by using an adaptive natural weight and its calculation method, and by efficiently integrating user browsing behavior and web document content.

    Schoeffmann, Klaus; Hopfgartner, Frank; Marques, Oge; Boeszoermenyi, Laszlo; Jose, Joemon M.

    2010-01-01

    We present a comprehensive review of the state of the art in video browsing and retrieval systems, with special emphasis on interfaces and applications. There has been a significant increase in activity (e.g., storage, retrieval, and sharing) employing video data in the past decade, both for personal and professional use. The ever-growing amount of video content available for human consumption and the inherent characteristics of video data-which, if presented in its raw format, is rather unwieldy and costly-have become driving forces for the development of more effective solutions to present video contents and allow rich user interaction. As a result, there are many contemporary research efforts toward developing better video browsing solutions, which we summarize. We review more than 40 different video browsing and retrieval interfaces and classify them into three groups: applications that use video-player-like interaction, video retrieval applications, and browsing solutions based on video surrogates. For each category, we present a summary of existing work, highlight the technical aspects of each solution, and compare them against each other.

    QDPHOT is a fast CCD stellar photometry task which quickly produces CCD stellar photometry from two CCD images of a star field. It was designed to be a data mining tool for finding high-quality stellar observations in the data archives of the National Virtual Observatory. QDPHOT typically takes just a few seconds to analyze two Hubble Space Telescope WFPC2 observations of Local Group star clusters. It is also suitable for real-time data-quality analysis of CCD observations; on-the-fly instrumental color-magnitude diagrams can be produced at the telescope console during the few seconds between CCD readouts.

  12. Browsing the Internet: good-bye anonymity!

    CERN Multimedia

    Computer Security Team

    2012-01-01

    Do you consider browsing the Internet to be your private business? When visiting random web-sites, how far do you assume you are anonymous? Would it matter to you that Google or Facebook can profile your browsing behaviour in order to better target you with advertisements? Did you notice that you already get targeted ads when you are logged on to Google or Facebook even if you are visiting completely different websites? If matters to you, note that browsing anonymously on the Internet is far from easy.   When you are connected to the Internet, you give away a variety of information: your PC’s IP address, some browser settings like language or screen size, and, probably, your login information. So how private is private? You might argue that your current IP address has been picked from a pool of addresses and therefore regularly changes, so it does not necessarily always pinpoint you. On the other hand, with the dawn of IPv6 there is no need any more for shared IP addresses as the...

  13. Observing Strategies Used by Children When Selecting Books to Browse, Read or Borrow

    2008-06-01

    Full Text Available This paper described 1. the investigation undertaken to trace the strategies used by children in selecting books to borrow, use or browse in two children’s public libraries, and 2. map the information seeking patterns adopted by the selected children. The sample comprised 43 children who used the Bayan Budiman Children’s Library, Petaling Jaya and the Kuala Lumpur Children’s Library. The children were randomly chosen, aged between 7 and 12 and comprised those who entered the library with the observed behaviour of selecting books to browse, use or borrow. Two stages were used to collect data; 1. observing the children’s behavior as they enter the library to the point when they pick up a book to browse, read or borrow for fifteen to twenty minutes and 2. interviewing those selected with a semi-structure questionnaire. Belkin, et al’s (1993 information search strategy (ISS dimensions were used to transcribe children’s browsing and selecting behavior. Based on the observations and interviews respondent’s behaviour was mapped to illustrate the children’s choosing process. The findings indicated that 1. browsing was the most popular method used when choosing a book combined with various strategies such as looking for a book by an author or series, finding a book by subjects, visually or physically scanning and recognizing the physical composition of the book; 2. children based their selection on the storyline, illustrations, cover designs and typography of the books; and 3. the searching behaviour is likely to be non-linear in nature. The majority of the children faced no problems in choosing or locating a book as most are regular visitors. A few indicated being overwhelmed by the library’s large collection or, face initial confusion before they started to browse and interact with resources. Children used visual cues rather from textual information when searching for books, inferring that children libraries need to be supported with

    2012-11-01

    Exploring key demographic parameters for establishment and growth of shrub populations enables us to identify the life stages or plant organs that browsers need to consume to effectively influence shrub population dynamics. However, there is a lack of concrete knowledge on how browsing can efficiently meet this goal. We therefore tested the impact of different levels of browsing intensity on a key demographic parameter (survival of juveniles) of a major colonizing shrub species (broom, Cytisus scoparius) in order to control population growth, and designed a browsing management strategy focused on this target stage. Three browsing intensities, representing pertinent management practices, were simulated on juveniles (2 years old) in a broom population. Juvenile broom plants were either left untouched (control treatment; n = 126) or had 50% or 90% of their total edible stem biomass removed for "light-intensity browsing" (n = 127) and "high-intensity browsing" (n = 77) treatments, respectively. Survival and fecundity data were collected over 6 years. Standard matrix modeling was used to analyze the impact of browsing on changes in population growth rate (λ), and the results were 6.34 (control), 2.26 (light browsing) and 0.85 (heavy browsing). Therefore, the natural expansion of broom populations may be slowed by light browsing or even reversed by heavy browsing (λ < 1). This multi-year survey confirms that focusing browsing on juveniles is an efficient strategy for controlling broom dominance. Shrub control strategies should therefore target early-growth-stage populations and repeat the browsing strategy at the same intensity over several years to achieve cumulative effects.

  16. Query sensitive comparative summarization of search results using concept based segmentation

    CERN Document Server

    Chitra, P; Sarukesi, K

    2012-01-01

    Query sensitive summarization aims at providing the users with the summary of the contents of single or multiple web pages based on the search query. This paper proposes a novel idea of generating a comparative summary from a set of URLs from the search result. User selects a set of web page links from the search result produced by search engine. Comparative summary of these selected web sites is generated. This method makes use of HTML DOM tree structure of these web pages. HTML documents are segmented into set of concept blocks. Sentence score of each concept block is computed with respect to the query and feature keywords. The important sentences from the concept blocks of different web pages are extracted to compose the comparative summary on the fly. This system reduces the time and effort required for the user to browse various web sites to compare the information. The comparative summary of the contents would help the users in quick decision making.

    2004-12-01

    Full Text Available Abstract Background Alignment and comparison of related genome sequences is a powerful method to identify regions likely to contain functional elements. Such analyses are data intensive, requiring the inclusion of genomic multiple sequence alignments, sequence annotations, and scores describing regional attributes of columns in the alignment. Visualization and browsing of results can be difficult, and there are currently limited software options for performing this task. Results The Application for Browsing Constraints (ABC is interactive Java software for intuitive and efficient exploration of multiple sequence alignments and data typically associated with alignments. It is used to move quickly from a summary view of the entire alignment via arbitrary levels of resolution to individual alignment columns. It allows for the simultaneous display of quantitative data, (e.g., sequence similarity or evolutionary rates and annotation data (e.g. the locations of genes, repeats, and constrained elements. It can be used to facilitate basic comparative sequence tasks, such as export of data in plain-text formats, visualization of phylogenetic trees, and generation of alignment summary graphics. Conclusions The ABC is a lightweight, stand-alone, and flexible graphical user interface for browsing genomic multiple sequence alignments of specific loci, up to hundreds of kilobases or a few megabases in length. It is coded in Java for cross-platform use and the program and source code are freely available under the General Public License.

    Nagino, Norikatsu; Yamada, Seiji

    In this paper, we propose a Future View system that assists user's usual Web browsing. The Future View will prefetch Web pages based on user's browsing strategies and present them to a user in order to assist Web browsing. To learn user's browsing strategy, the Future View uses two types of learning classifier systems: a content-based classifier system for contents change patterns and an action-based classifier system for user's action patterns. The results of learning is applied to crawling by Web robots, and the gathered Web pages are presented to a user through a Web browser interface. We experimentally show effectiveness of navigation using the Future View.

  1. Social Browsing & Information Filtering in Social Media

    CERN Document Server

    Lerman, Kristina

    2007-01-01

    Social networks are a prominent feature of many social media sites, a new generation of Web sites that allow users to create and share content. Sites such as Digg, Flickr, and Del.icio.us allow users to designate others as "friends" or "contacts" and provide a single-click interface to track friends' activity. How are these social networks used? Unlike pure social networking sites (e.g., LinkedIn and Facebook), which allow users to articulate their online professional and personal relationships, social media sites are not, for the most part, aimed at helping users create or foster online relationships. Instead, we claim that social media users create social networks to express their tastes and interests, and use them to filter the vast stream of new submissions to find interesting content. Social networks, in fact, facilitate new ways of interacting with information: what we call social browsing. Through an extensive analysis of data from Digg and Flickr, we show that social browsing is one of the primary usa...

  4. RAPID INDUCTION OF MULTIPLE TAXONOMIES FOR ENHANCED FACETED TEXT BROWSING

    Directory of Open Access Journals (Sweden)

    Lawrence Muchemi 1

    2016-07-01

    Full Text Available In this paper we present and compare two methodologies for rapidly inducing multiple subject-specific taxonomies from crawled data. The first method involves a sentence-level words co-occurrence frequency method for building the taxonomy, while the second involves the bootstrapping of a Word2Vec based algorithm with a directed crawler. We exploit the multilingual open-content directory of the World Wide Web, DMOZ1 to seed the crawl, and the domain name to direct the crawl. This domain corpus is then input to our algorithm that can automatically induce taxonomies. The induced taxonomies provide hierarchical semantic dimensions for the purposes of faceted browsing. As part of an ongoing personal semantics project, we applied the resulting taxonomies to personal social media data Twitter, Gmail, Facebook, Instagram, Flickr with an objective of enhancing an individual’s exploration of their personal information through faceted searching. We also perform a comprehensive corpus based evaluation of the algorithms based on many datasets drawn from the fields of medicine (diseases and leisure (hobbies and show that the induced taxonomies are of high quality.

  5. Visual Browsing of Earth and Environmental Science Topics to Enhance Data Discovery

    Science.gov (United States)

    Rebich Hespanha, S.; Adams, B.; Schildhauer, M.

    2013-12-01

    As Earth and environmental scientists gather more and more data at faster and faster rates, archiving, managing and providing efficient access to those data have become important challenges. Data repository efforts have made progress with the difficult task of collecting and curating data for the purposes of preservation, sharing, and reuse. However, because of incomplete metadata or lack of standardization in the way these data are described and indexed, it often remains difficult for researchers to identify data sets of potential value from a rapidly growing corpus. Here we describe a method that couples text mining (topic modeling using Latent Dirichlet Allocation, or LDA) of repository metadata records with Self-Organizing Map (SOM) visualizations to enable potential data users to browse thematically across a number of data repositories. Visual thematic browsing capabilities help minimize the chances that someone searching for data will miss relevant data sets due to a mismatch between the user's query and terms that appear in the object's metadata. To augment the value of this visual, metadata-driven browsing approach, we also performed these text mining and visualization procedures on a corpus of over 121,000 abstracts from top Earth and environmental science journals. We then use the resulting broader and richer ';map' of Earth and environmental science drawn from these abstracts to better contextualize the repository metadata for visual browsing purposes. Finally, we demonstrate how visualization of this corpus of primary literature can serve as an entry point for discovery of ';dark' or ';long-tail' data that have not yet been made accessible through data repositories or other data-sharing means.

    Full Text Available Abstract Background maxdLoad2 is a relational database schema and Java® application for microarray experimental annotation and storage. It is compliant with all standards for microarray meta-data capture; including the specification of what data should be recorded, extensive use of standard ontologies and support for data exchange formats. The output from maxdLoad2 is of a form acceptable for submission to the ArrayExpress microarray repository at the European Bioinformatics Institute. maxdBrowse is a PHP web-application that makes contents of maxdLoad2 databases accessible via web-browser, the command-line and web-service environments. It thus acts as both a dissemination and data-mining tool. Results maxdLoad2 presents an easy-to-use interface to an underlying relational database and provides a full complement of facilities for browsing, searching and editing. There is a tree-based visualization of data connectivity and the ability to explore the links between any pair of data elements, irrespective of how many intermediate links lie between them. Its principle novel features are: • the flexibility of the meta-data that can be captured, • the tools provided for importing data from spreadsheets and other tabular representations, • the tools provided for the automatic creation of structured documents, • the ability to browse and access the data via web and web-services interfaces. Within maxdLoad2 it is very straightforward to customise the meta-data that is being captured or change the definitions of the meta-data. These meta-data definitions are stored within the database itself allowing client software to connect properly to a modified database without having to be specially configured. The meta-data definitions (configuration file can also be centralized allowing changes made in response to revisions of standards or terminologies to be propagated to clients without user intervention. maxdBrowse is hosted on a web-server and presents

  12. Silvicultural Attempts to Induce Browse Resistance in Conifer Seedlings

    2011-01-01

    Full Text Available A multiyear study was conducted to determine if soil amendment combined with topical application of elemental sulfur could be employed to reduce deer browse damage to four conifer species. Fertilizer and sulfur were applied to conifer seedlings at seven sites near Corvallis, OR. Growth and browse damage data were collected for all seedlings over a period of 17 months. Additionally, foliar concentrations of monoterpenes and simple carbohydrates were assessed in western redcedar (Thuja plicata seedlings over a period of three years. Fertilization and sulfur treatments had a moderate impact on growth and no influence on browse damage or the chemical responses. Over the course of the study, browse damage diminished while foliar monoterpene concentrations increased in redcedar. It appears that silvicultural manipulation via sulfur application and/or soil amendment cannot accelerate or alter the ontogenetical changes that may naturally defend seedlings against mammalian herbivores. In a brief trial with captive deer, redcedar browse resistance was influenced by seedling maturation, but not monoterpene content. Other maturation effects may yield significant browse protection to young seedlings.

  13. Does browsing reduce shrub survival and vigor following summer fires?

    2011-01-01

    Periodic fire is widely hypothesized to limit woody plant encroachment in semiarid grasslands. In southern Texas, however, most of the woody plants that have invaded grasslands during the past two centuries are resistant to fire. We hypothesized that browsing by Odocoileus virginianus increases mortality of palatable shrubs and reduces vigor of shrubs following fire. We randomly selected ten pairs of each of three shrub species -Condalia hookeri, Acacia farnesiana, and Celtis ehrenbergiana - in each of three locations before prescribed burns during summer 2001. Following burns, we used a wire fence to protect one shrub of each pair from browsing. We estimated intensity of O. virginianus browsing and number and height of sprouts 4, 12, 20, 30, 38, and 47 weeks post-fire. We determined shrub height, survival, and biomass one year post-fire. Averaged across species, browsing intensity on unfenced shrubs was greater (LS Means, P 0.05) one year post-burn. Browsing by O. virginianus at the intensity in our study does not increase mortality or reduce vigor of C. hookeri, A. farnesiana, and Condalia ehrenbergiana producing new growth following destruction of aboveground tissues by a single fire compared to shrubs that are not browsed following fire.

    2009-01-01

    The Gene Ontology (GO) has proven to be a valuable resource for functional annotation of gene products. At well over 27 000 terms, the descriptiveness of GO has increased rapidly in line with the biological data it represents. Therefore, it is vital to be able to easily and quickly mine the functional information that has been made available through these GO terms being associated with gene products. QuickGO is a fast, web-based tool for browsing the GO and all associated GO annotations provided by the GOA group. After undergoing a redevelopment, QuickGO is now able to offer many more features beyond simple browsing. Users have responded well to the new tool and given very positive feedback about its usefulness. This tutorial will demonstrate how some of these features could be useful to the researcher wanting to discover more about their dataset, particular areas of biology or to find new ways of directing their research.Database URL:http://www.ebi.ac.uk/QuickGO.

    Linked environmental data has started to appear on the Web as environmental researchers make use of technologies such as ontologies, RDF, and SPARQL. Many of these datasets have an important geospatial and temporal dimension. The same is true also for the Web of data that is being rapidly populated not only with geospatial information, but also with temporal information. As the real-world entities represented in linked geospatial datasets evolve over time, the datasets themselves get updated and both the spatial and the temporal dimension of data become significant for users. For example, in the Earth Observation and Environment domains, data is constantly produced by satellite sensors and is associated with metadata containing, among others, temporal attributes, such as the time that an image was acquired. In addition, the acquisitions are considered to be valid for specific periods of time, for example until they get updated by new acquisitions. Satellite acquisitions might be utilized in applications such as the CORINE Land Cover programme operated by the European Environment Agency that makes available as a cartographic product the land cover of European areas. Periodically CORINE publishes the changes in the land cover of these areas in the form of changesets. Tools for exploiting the abundance of geospatial information have also started to emerge. However, these tools are designed for browsing a single data source, while in addition they cannot represent the temporal dimension. This is for two reasons: a) the lack of an implementation of a data model and a query language with temporal features covering the various semantics associated with the representation of time (e.g., valid and user-defined), and b) the lack of a standard temporal extension of RDF that would allow practitioners to utilize when publishing RDF data. Recently, we presented the temporal features of the data model stRDF, the query language stSPARQL, and their implementation in the geospatial

  16. Does pollination limit tolerance to browsing in Ipomopsis aggregata?

    Science.gov (United States)

    Sharaf, Katherine E; Price, Mary V

    2004-02-01

    Ungulate browsing of flowering stalks of the semelparous herb Ipomopsis aggregata leads to regrowth of lateral inflorescences, a response that has been reported to yield overcompensation in some cases (browsed plants with higher reproductive success than unbrowsed), but undercompensation in others. Little is known about the mechanisms that cause such variable tolerance to herbivory. We explored one possible mechanism--variation in effects of browsing on pollination--by clipping I. aggregata inflorescences to mimic browsing, observing subsequent visits by pollinators and nectar-robbers, and adding pollen by hand to flowers of some clipped and unclipped plants. Clipping reduced floral display size and increased inflorescence branching, but neither hummingbirds, the primary pollinators, nor nectar-robbing bumblebees showed any preference for unclipped versus clipped plants. Clipping delayed flowering; this shift in phenology caused clipped plants to miss the peak of hummingbird activity and to have lower per-flower visitation rates than unclipped controls in one year, but to have greater overlap with birds and higher visitation rates in the subsequent year. In three sites and 2 years, clipped plants exposed to natural pollination suffered extreme undercompensation, producing on average only 16% as many seeds as unclipped controls. This was not directly attributable to clipping effects on pollination, however, because clipped plants were unable to increase fecundity when provided with supplemental pollen by hand. Taken altogether, our results suggest that compensation was constrained less by indirect effects of browsing on pollination than by its direct impacts on resource availability and hence on the ability of plants to regrow lost inflorescence tissue and to fill seeds. Exploring the physiological and developmental processes involved in regrowth of inflorescences and provisioning of seeds is a promising future direction for research designed to understand variation

  19. Massively parallel neural network intelligent browse

    Science.gov (United States)

    Maxwell, Thomas P.; Zion, Philip M.

    1992-04-01

    A massively parallel neural network architecture is currently being developed as a potential component of a distributed information system in support of NASA's Earth Observing System. This architecture can be trained, via an iterative learning process, to recognize objects in images based on texture features, allowing scientists to search for all patterns which are similar to a target pattern in a database of images. It may facilitate scientific inquiry by allowing scientists to automatically search for physical features of interest in a database through computer pattern recognition, alleviating the need for exhaustive visual searches through possibly thousands of images. The architecture is implemented on a Connection Machine such that each physical processor contains a simulated 'neuron' which views a feature vector derived from a subregion of the input image. Each of these neurons is trained, via the perceptron rule, to identify the same pattern. The network output gives a probability distribution over the input image of finding the target pattern in a given region. In initial tests the architecture was trained to separate regions containing clouds from clear regions in 512 by 512 pixel AVHRR images. We found that in about 10 minutes we can train a network to perform with high accuracy in recognizing clouds which were texturally similar to a target cloud group. These promising results suggest that this type of architecture may play a significant role in coping with the forthcoming flood of data from the Earth-monitoring missions of the major space-faring nations.

    1999-12-01

    It is well established that humans possess cognitive abilities to process images extremely rapidly. At GTE Laboratories we have been experimenting with Web-based browsing interfaces that take advantage of this human facility. We have prototyped a number of browsing applications in different domains that offer the advantages of high interactivity and visual engagement. Our hypothesis, confirmed by user evaluations and a pilot experiment, is that many users will be drawn to interfaces that provide rapid presentation of images for browsing tasks in many contexts, among them online shopping, multimedia title selection, and people directories. In this paper we present our application prototypes using a system called PolyNav and discuss the imaging requirements for applications like these. We also raise the suggestion that if the Web industry at large standardized on an XML for meta-content that included images, then the possibility exist that rapid-fire image browsing could become a standard part of the Web experience for content selection in a variety of domains.

    2015-12-01

    The Gulf of Mexico Coastal Ocean Observing System Regional Association (GCOOS-RA) is one of eleven Regional Associations organized under the NOAA-led U.S. Integrated Ocean Observing System (IOOS) Program Office. Each of the RAs operate standards-based regional data portals designed to aggregate near real-time and historical observed data and modeled outputs from distributed providers and to offer these and derived products in standardized ways to a diverse set of users. The RA's portals are based on the IOOS Data and Communications Plan which describes the functional elements needed for an interoperable system. One of these elements is called "Uniform On-line Browse" which is an informational service designed primarily to visualize the inventory of a portal. An on-line browse service supports the end user's need to discover what parameters are available, to learn the spatial and temporal extend of the holdings, and to examine the character of the data (e.g, variability, gappiness, etc). These pieces of information help the end user decide if the data are fit for his/her purpose and to construct valid data requests. Note that on-line browse is a distinctly different activity than data analysis because it seeks to yield knowledge about the inventory and not about what the data mean. "Uniform" on-line browse is a service that takes advantage of the standardization of the data portal's data access points. Most portals represent station locations on a map. This is a view of the data inventory but these plots are rarely generated by pulling data through the standards-based services offered to the end users but through methods only available to the portal programmers. This work will present results of Uniform On-line browse tools developed within GCOOS-RA and their applicability to other RA portals.

  6. Quickly making the correct choice.

    2015-08-01

    In daily life, unconscious choices guide many of our on-going actions. Such choices need to be made quickly, because the options change as the action progresses. We confirmed that people make reasonable choices when they have to quickly decide between two alternatives, and studied the basis of such decisions. The task was to tap with their finger on as many targets as possible within 2 min. A new target appeared after every tap, sometimes accompanied by a second target that was easier to hit. When there was only one target, subjects had to find the right balance between speed and accuracy. When there were two targets, they also had to choose between them. We examined to what extent subjects switched to the target that was easier to hit when it appeared some time after the original one. Subjects generally switched to the easier target whenever doing so would help them hit more targets within the 2-min session. This was so, irrespective of whether the different delays were presented in separate sessions or were interleaved within one session. Whether or not they switched did not depend on how successful they were at hitting the targets on earlier attempts, but it did depend on the position of the finger at the moment that the easy target appeared. We conclude that people have continuous access to reasonable estimates of how long various movement options would take and of how precise the endpoints are likely to be, given the instantaneous circumstances.

    2015-01-01

    The QuickTox Kit for QuickScan Aflatoxin FREE uses competitive lateral flow technology and a reader based system for quantitative determination of total aflatoxins in varied matrixes. Aqueous based extraction protocols are used for corn and wheat, reducing use of solvents. Fifty percent ethanol (Reagent Alcohol) extraction is used for oats, sorghum, and barley. Eighty percent ethanol (Reagent Alcohol) extraction is used for whole peanut, peanut seed, and peanut hull samples. Matrix specific assay procedures and calibration curves are used to enable analyses across multiple sample types. The performance of this assay was examined using naturally contaminated aflatoxin corn samples and spiked samples of barley, oats, sorghum, wheat, whole peanut, peanut seed, and peanut hull samples. All data were judged against previously established acceptance criteria. Performance was evaluated in linearity, selectivity, matrix, lot consistency, and robustness experiments in the sponsor's laboratory. Results produced in all studies except robustness were within acceptable ranges. Out of range robustness study results reflected simultaneous deviation in sample volume and assay development time compared to the standard assay procedures. Aflatoxin B1, B2, and G1 were detected with approximately equal sensitivity; sensitivity for G2 was 64% that of B1. The presence of other common mycotoxins did not interfere with the assay. Matrix studies in an independent laboratory examined corn and barley to challenge both aqueous and ethanol based extraction procedures. All data points in these studies fell within the ranges defined in the acceptance criteria. The assay exhibited a linear dose response over the range tested, 0-100 ppb, with R(2) values exceeding 0.93 and RSDr values for results ranging from 2.27 to 23.84%. PMID:26651570

    2000-01-01

    Full Text Available Traditional on-line search services such as Dialog, DataStar and Lexis provide a wide range of search features (boolean and proximity operators, truncation, etc. This paper discusses the use of these features for effective searching, and argues that these features are required, regardless of advances in search engine technology. The literature on on-line searching is reviewed, identifying features that searchers find desirable for effective searching. A selective survey of current digital libraries available on the Web was undertaken, identifying which search features are present. The survey indicates that current digital libraries do not implement a wide range of search features. For instance: under half of the examples included controlled vocabulary, under half had proximity searching, only one enabled browsing of term indexes, and none of the digital libraries enable searchers to refine an initial search. Suggestions are made for enhancing the search effectiveness of digital libraries, for instance by: providing a full range of search operators, enabling browsing of search terms, enhancement of records with controlled vocabulary, enabling the refining of initial searches, etc.

    HT-7 is the first superconducting tokamak device for fusion research in China. Many experiments have been performed on the HT-7 tokamak since 1994 with numerous satisfactory results achieved in the fusion research field. As more and better communication is required with other fusion research laboratories, remote access to experimental data is becoming increasingly important in order to raise the degree of openness of experiments and to expand research results.The web-based remote data browsing system enables authorized users in geographically different locations to view and search for experimental data without having to install any utility software at their terminals. The three-tier software architecture and thin client technology are used to operate the system effectively. This paper describes the structure of the system and the realization of its functions, focusing on three main points: the communication between the participating tiers, the data structure of the system and the visualization of the raw data on web pages.

  11. Quick methods for radiochemical analysis

    International Nuclear Information System (INIS)

    Quick methods for radiochemical analysis, of adequate precision for the assay of a limited number of biologically important radionuclides, are important in the development of effective monitoring programs, particularly those that would be applied in emergency situations following an accidental release of radioactive substances. Methods of this type have been developed in a number of laboratories and are being altered and improved from time to time. The Agency invited several Member States to provide detailed information on any such procedures that might have been developed in their laboratories. From the information thus obtained a number of methods have been selected that appear to meet the criteria of speed and economy in the use of materials and equipment, and seem to be eminently suitable for those radionuclides that might be of major interest from the point of view of assessing the potential dose to persons following a serious dispersal of contamination.

    2011-01-01

    An increasing amount of data is published on the Web according to the Linked Open Data (LOD) principles. End users would like to browse these data in a flexible manner. In this paper we focus on similarity-based browsing and we introduce a novel method for computing the similarity between two entities of a given RDF/S graph. The distinctive characteristics of the proposed metric is that it is generic (it can be used to compare nodes of any kind), it takes into account the neighborhoods of the nodes, and it is configurable (with respect to the accuracy vs computational complexity tradeoff). We demonstrate the behavior of the metric using examples from an application over LOD. Finally, we generalize and elaborate on implementation approaches harmonized with the distributed nature of LOD which can be used for computing the most similar entities using neighborhood-based similarity metrics.

  1. Herbivory in a Mediterranean forest: browsing impact and plant compensation

    Science.gov (United States)

    Focardi, Stefano; Tinelli, Aleandro

    2005-11-01

    The compensatory response of plants to defoliation is likely to have important effects on plant-ungulate equilibria in forested ecosystems. We investigated the responses of six species of Mediterranean bushes to defoliation by wild ungulates, comparing an index of browsing impact with the productivity of plants in both open and exclusion plots. The data revealed a great diversity of plant responses to herbivory: Rubus ulmifolius was able to over-compensate and replace the lost tissues. Phillyrea latifolia exhibited a similar, albeit less evident, pattern, while Cistus salvifolius was severely damaged by browsing. Other species, such as Quercus ilex, Juncus acutus and Erica arborea, were not attacked to a large extent and suffered little or no harm. The results strongly suggest that Mediterranean ecosystems may tolerate large stocking rates of ungulates. However, the reduction of plant biomass due to browsing was very different in the six studied species, suggesting that when herbivory becomes severe the structure of the ecosystem will change with the more tolerant plants becoming more abundant. We can apply these results to improve management and conservation of relict coastal forests in the Mediterranean basin which are usually of small size and where decision-makers have to compromise between the conservation of plants and that of large mammals.

We will explore identification issues and solutions related to the dynamic generation of new data sets enabled by LaTiS. We are also improving the access to our metadata, including semantically enabling the site so that our data can be discovered, related concepts can be explored, our inventory can be browsed and searched, and our data understood well enough to be understood and used appropriately. This poster will describe the current state of LISIRD, provide details of the data sets it serves, demonstrate the role of the LaTiS middleware, discuss the assignment of unique identifiers to our data products, describe plans for integration of a semantically metadata database, and address other related aspects of serving spectral and other time series data.

    1998-05-01

    Several new web based services have been introduced this year by the Astrophysics Data Facility (ADF) at the NASA Goddard Space Flight Center. IMPReSS is a graphical interface to astrophysics databases that presents the user with the footprints of observations of space-based missions. It also aids astronomers in retrieving these data by sending requests to distributed data archives. The VIEWER is a reader of ADC astronomical catalogs and journal tables that allows subsetting of catalogs by column choices and range selection and provides database-like search capability within each table. With it, the user can easily find the table data most appropriate for their purposes and then download either the subset table or the original table. CATSEYE is a tool that plots output tables from the VIEWER (and soon AMASE), making exploring the datasets fast and easy. Having completed the basic functionality of these systems, we are enhancing the site to provide advanced functionality. These will include: market basket storage of tables and records of VIEWER output for IMPReSS and AstroBrowse queries, non-HTML table responses to AstroBrowse type queries, general column arithmetic, modularity to allow entrance into the sequence of web pages at any point, histogram plots, navigable maps, and overplotting of catalog objects on mission footprint maps. When completed, the ADF/ADC web facilities will provide astronomical tabled data and mission retrieval information in several hyperlinked environments geared for users at any level, from the school student to the typical astronomer to the expert datamining tools at state-of-the-art data centers.

    Directory of Open Access Journals (Sweden)

    L.H. Watson

    1999-01-01

    Full Text Available Grewia occidentalis plants in the study area generally occurred in bush clumps with other shrub species. Grewia occidentalis commonly occurred with Diospyros austro-africana, Rhus longispina and Rhus pollens (nurse shrubs, but seldom with Acacia kar-roo and Lycium cinereum (non-nurse shrubs. Eland browsed G. occidentalis plants at higher levels than other shrub species, but browsing was not evenly spread across all plants. Grewia occidentalis plants associated with nurse shrubs had lower levels of browsing than those growing alone and those growing with non-nurse shrubs, while G. occidentalis plants in the centre of nurse shrubs experienced the lowest levels of browsing. The latter group of plants also produced the most fruit. Eland browsing is consid-ered an important factor determining the distribution of G. occidentalis plants in the study area, while the presence of nurse shrubs is considered essential for the establishment and maintenance of the G. occidentalis population in the study area.

    Full Text Available In present days of growing information technology, many browsers available for surfing and web mining. A user has option to use any of them at a time to mine out the desired website. Every browser has pre-defined level of popularity and reputation in the market. This paper considers the setup of only two browsers in a computer system and a user prefers to any one, if fails, switches to the other one .The behavior of user is modeled through Markov chain procedure and transition probabilities are calculated. The quitting to browsing is treated as a parameter of variation over the popularity. Graphical study is performed to explain the inter relationship between user behavior parameters and browser market popularity parameters. If rate of a company is lowest in terms of browser failure and lowest in terms of quitting probability then company enjoys better popularity and larger user proportion

    2008-10-01

    Full Text Available Abstract Background The Bluejay genome browser has been developed over several years to address the challenges posed by the ever increasing number of data types as well as the increasing volume of data in genome research. Beginning with a browser capable of rendering views of XML-based genomic information and providing scalable vector graphics output, we have now completed version 1.0 of the system with many additional features. Our development efforts were guided by our observation that biologists who use both gene expression profiling and comparative genomics gain functional insights above and beyond those provided by traditional per-gene analyses. Results Bluejay 1.0 is a genome viewer integrating genome annotation with: (i gene expression information; and (ii comparative analysis with an unlimited number of other genomes in the same view. This allows the biologist to see a gene not just in the context of its genome, but also its regulation and its evolution. Bluejay now has rich provision for personalization by users: (i numerous display customization features; (ii the availability of waypoints for marking multiple points of interest on a genome and subsequently utilizing them; and (iii the ability to take user relevance feedback of annotated genes or textual items to offer personalized recommendations. Bluejay 1.0 also embeds the Seahawk browser for the Moby protocol, enabling users to seamlessly invoke hundreds of Web Services on genomic data of interest without any hard-coding. Conclusion Bluejay offers a unique set of customizable genome-browsing features, with the goal of allowing biologists to quickly focus on, analyze, compare, and retrieve related information on the parts of the genomic data they are most interested in. We expect these capabilities of Bluejay to benefit the many biologists who want to answer complex questions using the information available from completely sequenced genomes.

    Full Text Available Through the help of many examples, the author analyzes the uses of the Quick Response (QR Code in libraries. QR is a bidimensional code composed by black and white pixels into a squared matrix, containing information to be enjoyed with the help of smartphones or similar devices. Scanning the code, which is usually printed on newspapers, posters, or captions, and processing it with ad-hoc software, users can obtain additional information and data on objects or services without extra searches.Considering the widespread circulation of mobile devices (such as smartphones among users, many libraries are experimenting the usage of the QR to deliver library services in a friendly and quick way. The Half Hollow Hills Community Library (New York, the Abilene Christian University (Texas, and the San Diego State University Library are using the QR code to give their users access to guides, manuals, library map, audio and video files. The University of Huddersfield Library (United Kingdom applies the QR code to various areas: links to electronic resources, explanatory videos, phone numbers, and as a support of the library's OPAC.The University of Bath Library's online catalogue automatically incorporates into catalographic records, both of monographs and journals, QR codes encoding author, title, and call number. However, the widespread use of QR codes is due to the fact that users own a smartphone, and that many OPACs are made to be explored and navigated with such kind of devices.Attraverso numerosi esempi, si analizzano gli usi finora sperimentati nelle biblioteche dei codici Quick Response (QR.

    We study the rheology of quick clay, an unstable soil responsible for many landslides. We show that above a critical stress the material starts flowing abruptly with a very large viscosity decrease caused by the flow. This leads to avalanche behavior that accounts for the instability of quick clay soils. Reproducing landslides on a small scale in the laboratory shows that an additional factor that determines the violence of the slides is the inhomogeneity of the flow. We propose a simple yield stress model capable of reproducing the laboratory landslide data, allowing us to relate landslides to the measured rheology. PMID:19905837

  5. Browsing the fusion data in a Google map way

    International Nuclear Information System (INIS)

    Full text of publication follows. How to access the ITER data is still an open issue. Concepts from KSTAR(1), W7X(2), EAST(3), and DIIID(4) have been presented. In this paper, a new web application to browse the fusion data in a Google map way is demonstrated on HL-2A database. This dynamic and interactive web application can run in any popular browser(IE, safari, Firefox, Opera), by any hardware (smart phone, PC, ipad, Mac) and operating system (ios, android, windows, linux, Mac OS). No any plug-ins is needed. The details of the framework for this web application are presented. The framework consists of three layers. The front top client layer is developed by Jquery code. The middle layer, which plays a role of a bridge to connect the server and client is developed by PHP code. The behind server layer is developed by Matlab, which responses any command from the front top client, retrieves the data from the HL-2A database, analyses and processes the data, and finally, returns the data to the client in client's favorite way. The way to browse and retrieve the fusion data is well welcomed by many researchers who access fusion data from many other machines. This way may apply to other machines, and present useful idea to the way for accessing ITER data in the future.

    Rosales, Keisa R.; Stoltzfus, Joel M.

    2009-01-01

    NASA Johnson Space Center White Sands Test Facility (WSTF) performed particle impact testing to determine whether there is a particle impact ignition hazard in the quick disconnects (QDs) in the Environmental Control and Life Support System (ECLSS) on the International Space Station (ISS). Testing included standard supersonic and subsonic particle impact tests on 15-5 PH stainless steel, as well as tests performed on a QD simulator. This paper summarizes the particle impact tests completed at WSTF. Although there was an ignition in Test Series 4, it was determined the ignition was caused by the presence of a machining imperfection. The sum of all the test results indicates that there is no particle impact ignition hazard in the ISS ECLSS QDs. KEYWORDS: quick disconnect, high pressure, particle impact testing, stainless steel

  19. Ungulate browsing maintains shrub diversity in the absence of episodic disturbance in seasonally-arid conifer forest.

    Directory of Open Access Journals (Sweden)

    Burak K Pekin

    Full Text Available Ungulates exert a strong influence on the composition and diversity of vegetation communities. However, little is known about how ungulate browsing pressure interacts with episodic disturbances such as fire and stand thinning. We assessed shrub responses to variable browsing pressure by cattle and elk in fuels treated (mechanical removal of fuels followed by prescribed burning and non-fuels treated forest sites in northeastern Oregon, US. Seven treatment paddocks were established at each site; three with cattle exclusion and low, moderate and high elk browsing pressure, three with elk exclusion and low, moderate and high cattle browsing pressure, and one with both cattle and elk exclusion. The height, cover and number of stems of each shrub species were recorded at multiple plots within each paddock at the time of establishment and six years later. Changes in shrub species composition over the six year period were explored using multivariate analyses. Generalized Linear Mixed Models were used to determine the effect of browsing pressure on the change in shrub diversity and evenness. Vegetation composition in un-browsed paddocks changed more strongly and in different trajectories than in browsed paddocks at sites that were not fuels treated. In fuels treated sites, changes in composition were minimal for un-browsed paddocks. Shrub diversity and evenness decreased strongly in un-browsed paddocks relative to paddocks with low, moderate and high browsing pressure at non-fuels treated sites, but not at fuels treated sites. These results suggest that in the combined absence of fire, mechanical thinning and ungulate browsing, shrub diversity is reduced due to increased dominance by certain shrub species which are otherwise suppressed by ungulates and/or fuels removal. Accordingly, ungulate browsing, even at low intensities, can be used to suppress dominant shrub species and maintain diversity in the absence of episodic disturbance events.

    Full Text Available Abstract Background The volume of health science publications is escalating rapidly. Thus, keeping up with developments is becoming harder as is the task of finding important cross-domain connections. When geographic location is a relevant component of research reported in publications, these tasks are more difficult because standard search and indexing facilities have limited or no ability to identify geographic foci in documents. This paper introduces HEALTH GeoJunction, a web application that supports researchers in the task of quickly finding scientific publications that are relevant geographically and temporally as well as thematically. Results HEALTH GeoJunction is a geovisual analytics-enabled web application providing: (a web services using computational reasoning methods to extract place-time-concept information from bibliographic data for documents and (b visually-enabled place-time-concept query, filtering, and contextualizing tools that apply to both the documents and their extracted content. This paper focuses specifically on strategies for visually-enabled, iterative, facet-like, place-time-concept filtering that allows analysts to quickly drill down to scientific findings of interest in PubMed abstracts and to explore relations among abstracts and extracted concepts in place and time. The approach enables analysts to: find publications without knowing all relevant query parameters, recognize unanticipated geographic relations within and among documents in multiple health domains, identify the thematic emphasis of research targeting particular places, notice changes in concepts over time, and notice changes in places where concepts are emphasized. Conclusions PubMed is a database of over 19 million biomedical abstracts and citations maintained by the National Center for Biotechnology Information; achieving quick filtering is an important contribution due to the database size. Including geography in filters is important due to

    2015-04-01

    Full Text Available User profiling is an important and basic component in personalized search engine. Search engines respond to a user’s query by using the bag-of-words model, which matches keyword between the query and web documents but ignore contexts and users’ preferences. Personalized search greatly improves the search results as of the results provided by the search engine without personalization. In this paper, the performance of personalized search based on content analysis and personalized search based on user group have been evaluated. In personalized search based on content analysis the contents are traced by finding the user’s browsed documents and search history, which reduce the users search time. In user profile only user preference alone is taken into consideration. The experimental results show that the personalized search based on user group method having higher precision and recall rate than the content analysis method.

    Full Text Available The nutritional value of browse foliage from the Thorny Kalahari Dune Bush veld of South Africa is not characterized. Most of this browse species is rich in tannin, but still palatable, and is consumed by ruminants during the dry season, as well as having a role to play in mitigating enteric methane emission from ruminants. In this study, the rumen methane mitigation potential of 19 browse species foliage collected from the Thorny Kalahari Dune Bush veld, was analyzed in terms of chemical composition, in vitro fermentation, digestibility and methane production. In vitro gas and methane production and organic matter digestibility (IVOMD were determined by using rumen fluid collected, strained and anaerobically prepared. A semi-automated system was used to measure gas production (GP from each browse species by incubating 400 mg samples in a shaking incubator at 39 °C with or without inclusion of 400 mg of polyethylene glycol (PEG. Data for all the parameters collected were statistically analyzed using the SAS (9.0 general linear model (GLM procedure, and differences between foliage species were determined using Duncan’s multiple-range test. Acacia luederitziiand Monechma incanumshowed the best potential for decreasing methane production by up to 90 % after 48 h of incubation. The secondary components (mainly tannins of the browse species appeared to have a significant effect on volatile fatty acids (VFA, methane and gas production as judged by the comparison of samples incubated with or without PEG inclusion. The substantial amount of crude protein (CP content coupled with their anti-methanogenic effect during fermentation would make these browses a potential mitigation option for small scale farmers and pastoralists in sub-Sahara Africa. However, it is also very important that systematic and strategic supplementation in a mixed diet should be looked at as the way forward in terms of best utilization.

    Fly ash is a fine powdery material created when coal is burned to generate electricity. Before escaping into the environment via the utility stacks, the ash is collected and may be stored for beneficial uses or disposed of, if necessary. The use of fly ash provides environmental benefits, such as the conservation of natural resources, the reduction of greenhouse gas emissions and eliminating the needed for ash disposal in landfills. It is also a valuable mineral resource that is used in construction and manufacturing. Fly ash is used in the production of Portland cement, concrete, mortars and stuccos, manufactured aggregates along with various agricultural applications. As mineral filler, fly ash can be used for paints, shingles, carpet backing, plastics, metal castings and other purposes. This quick reference card is intended to provide the reader basic source, identification and composition, information specifically related to fly ash.

  16. Rocky Planet Formation: Quick and Neat

    CERN Document Server

    Kenyon, Scott J; Bromley, Benjamin C

    2016-01-01

    We reconsider the commonly held assumption that warm debris disks are tracers of terrestrial planet formation. The high occurrence rate inferred for Earth-mass planets around mature solar-type stars based on exoplanet surveys (roughly 20%) stands in stark contrast to the low incidence rate (less than 2-3%) of warm dusty debris around solar-type stars during the expected epoch of terrestrial planet assembly (roughly 10 Myr). If Earth-mass planets at AU distances are a common outcome of the planet formation process, this discrepancy suggests that rocky planet formation occurs more quickly and/or is much neater than traditionally believed, leaving behind little in the way of a dust signature. Alternatively, the incidence rate of terrestrial planets has been overestimated or some previously unrecognized physical mechanism removes warm dust efficiently from the terrestrial planet region. A promising removal mechanism is gas drag in a residual gaseous disk with a surface density of roughly or somewhat more than 0.0...

  17. Change in Mesoherbivore Browsing Is Mediated by Elephant and Hillslope Position.

    Directory of Open Access Journals (Sweden)

    D D Georgette Lagendijk

    Full Text Available Elephant are considered major drivers of ecosystems, but their effects within small-scale landscape features and on other herbivores still remain unclear. Elephant impact on vegetation has been widely studied in areas where elephant have been present for many years. We therefore examined the combined effect of short-term elephant presence (< 4 years and hillslope position on tree species assemblages, resource availability, browsing intensity and soil properties. Short-term elephant presence did not affect woody species assemblages, but did affect height distribution, with greater sapling densities in elephant access areas. Overall tree and stem densities were also not affected by elephant. By contrast, slope position affected woody species assemblages, but not height distributions and densities. Variation in species assemblages was statistically best explained by levels of total cations, Zinc, sand and clay. Although elephant and mesoherbivore browsing intensities were unaffected by slope position, we found lower mesoherbivore browsing intensity on crests with high elephant browsing intensity. Thus, elephant appear to indirectly facilitate the survival of saplings, via the displacement of mesoherbivores, providing a window of opportunity for saplings to grow into taller trees. In the short-term, effects of elephant can be minor and in the opposite direction of expectation. In addition, such behavioural displacement promotes recruitment of saplings into larger height classes. The interaction between slope position and elephant effect found here is in contrast with other studies, and illustrates the importance of examining ecosystem complexity as a function of variation in species presence and topography. The absence of a direct effect of elephant on vegetation, but the presence of an effect on mesoherbivore browsing, is relevant for conservation areas especially where both herbivore groups are actively managed.

    For the Library of Integrated Network-based Cellular Signatures (LINCS) project many gene expression signatures using the L1000 technology have been produced. The L1000 technology is a cost-effective method to profile gene expression in large scale. LINCS Canvas Browser (LCB) is an interactive HTML5 web-based software application that facilitates querying, browsing and interrogating many of the currently available LINCS L1000 data. LCB implements two compacted layered canvases, one to visualize clustered L1000 expression data, and the other to display enrichment analysis results using 30 different gene set libraries. Clicking on an experimental condition highlights gene-sets enriched for the differentially expressed genes from the selected experiment. A search interface allows users to input gene lists and query them against over 100 000 conditions to find the top matching experiments. The tool integrates many resources for an unprecedented potential for new discoveries in systems biology and systems pharmacology. The LCB application is available at http://www.maayanlab.net/LINCS/LCB. Customized versions will be made part of the http://lincscloud.org and http://lincs.hms.harvard.edu websites. PMID:24906883

    2015-01-01

    Full Text Available The number of RNA-Seq studies has grown in recent years. The design of RNA-Seq studies varies from very simple (e.g., two-condition case-control to very complicated (e.g., time series involving multiple samples at each time point with separate drug treatments. Most of these publically available RNA-Seq studies are deposited in NCBI databases, but their metadata are scattered throughout four different databases: Sequence Read Archive (SRA, Biosample, Bioprojects, and Gene Expression Omnibus (GEO. Although the NCBI web interface is able to provide all of the metadata information, it often requires significant effort to retrieve study- or project-level information by traversing through multiple hyperlinks and going to another page. Moreover, project- and study-level metadata lack manual or automatic curation by categories, such as disease type, time series, case-control, or replicate type, which are vital to comprehending any RNA-Seq study. Here we describe “MetaRNA-Seq,” a new tool for interactively browsing, searching, and annotating RNA-Seq metadata with the capability of semiautomatic curation at the study level.

    2011-01-01

    Background Patients with colorectal cancer who seek to improve their knowledge of health and treatment options can now access in a few seconds data that would previously have required hours of research. Our aim was to evaluate the attitudes of patients toward Web browsing for information on colorectal cancer. Methods We surveyed all patients attending a colorectal cancer follow-up clinic between January and August 2007 on their use of the Internet to obtain information on colorectal cancer. Results In all, 439 patients with mean age of 68.6 years participated in the study. Of these, 24% reported using the Internet to obtain colorectal cancer information. Most participants used the Google search engine. Only 13% of participants confirmed that colorectal cancer information on the Internet was helpful in decision-making. Patients under the age of 65 years were more likely to have Internet access (p < 0.001), more likely to use the Internet to find colorectal cancer information (p = 0.005) and more likely to access a site recommended by a colorectal specialist (p = 0.002). Among Internet users, men were slightly more likely than women to use the Internet, although the difference was not significant (p = 0.20). Conclusion The Internet is a useful tool for disseminating information about colorectal cancer. The best sites are still difficult for patients to distinguish from the thousands of sites returned by search engines. This study demonstrates that the level of potential interest is sufficient to justify the development of a departmental or regional colorectal cancer network of websites and indicates areas of interest for patients.

    A useful step towards better interpretation and analysis of the usage patterns is to formalize the semantics of the resources that users are accessing in the Web. We focus on this problem and present an approach for the semantic formalization of usage logs, which lays the basis for eective techniques of querying expressive usage patterns. We also present a query answering approach, which is useful to nd in the logs expressive patterns of usage behavior via formulation of semantic and temporal-based constraints. We have processed over 30 thousand user browsing sessions extracted from usage logs of DBPedia and Semantic Web Dog Food. All these events are formalized semantically using respective domain ontologies and RDF representations of the Web resources being accessed. We show the eectiveness of our approach through experimental results, providing in this way an exploratory analysis of the way users browse theWeb of Data.

    2011-12-01

    Spectral imaging technology have been used mostly in remote sensing, but have recently been extended to new area requiring high fidelity color reproductions like telemedicine, e-commerce, etc. These spectral imaging systems are important because they offer improved color reproduction quality not only for a standard observer under a particular illuminantion, but for any other individual exhibiting normal color vision capability under another illuminantion. A possibility for browsing of the archives is needed. In this paper, the authors present a new spectral image browsing architecture. The architecture for browsing is expressed as follow: (1) The spectral domain of the spectral image is reduced with the PCA transform. As a result of the PCA transform the eigenvectors and the eigenimages are obtained. (2) We quantize the eigenimages with the original bit depth of spectral image (e.g. if spectral image is originally 8bit, then quantize eigenimage to 8bit), and use 32bit floating numbers for the eigenvectors. (3) The first eigenimage is lossless compressed by JPEG-LS, the other eigenimages were lossy compressed by wavelet based SPIHT algorithm. For experimental evalution, the following measures were used. We used PSNR as the measurement for spectral accuracy. And for the evaluation of color reproducibility, ΔE was used.here standard D65 was used as a light source. To test the proposed method, we used FOREST and CORAL spectral image databases contrain 12 and 10 spectral images, respectively. The images were acquired in the range of 403-696nm. The size of the images were 128*128, the number of bands was 40 and the resolution was 8 bits per sample. Our experiments show the proposed compression method is suitable for browsing, i.e., for visual purpose.

  11. Mining Fuzzy Weighted Browsing Patterns from Time Duration and with Linguistic Thresholds

    Directory of Open Access Journals (Sweden)

    Tzung P. Hong

    2008-01-01

    Full Text Available World-wide-web applications have grown very rapidly and have made a significant impact on computer systems. Among them, web browsing for useful information may be most commonly seen. Due to its tremendous amounts of use, efficient and effective web retrieval has become a very important research topic in this field. Techniques of web mining have thus been requested and developed to achieve this purpose. In this research, a new fuzzy weighted web-mining algorithm is proposed, which can process web-server logs to discover useful users’ browsing behaviors from the time durations of the paged browsed. Since the time durations are numeric, fuzzy concepts are used here to process them and to form linguistic terms. Besides, different web pages may have different importance. The importance of web pages are evaluated by managers as linguistic terms, which are then transformed and averaged as fuzzy sets of weights. Each linguistic term is then weighted by the importance for its page. Only the linguistic term with the maximum cardinality for a page is chosen in later mining processes, thus reducing the time complexity. The minimum support is set linguistic, which is more natural and understandable for human beings. An example is given to clearly illustrate the proposed approach.

  12. CensorSpoofer: Asymmetric Communication with IP Spoofing for Censorship-Resistant Web Browsing

    CERN Document Server

    Wang, Qiyan; Nguyen, Giang T K; Houmansadr, Amir; Borisov, Nikita

    2012-01-01

    A key challenge in censorship-resistant web browsing is being able to direct legitimate users to redirection proxies while preventing censors, posing as insiders, from discovering their addresses and blocking them. We propose a new framework for censorship-resistant web browsing called {\\it CensorSpoofer} that addresses this challenge by exploiting the asymmetric nature of web browsing traffic and making use of IP spoofing. CensorSpoofer de-couples the upstream and downstream channels, using a low-bandwidth indirect channel for delivering outbound requests (URLs) and a high-bandwidth direct channel for downloading web content. The upstream channel hides the request contents using steganographic encoding within email or instant messages, whereas the downstream channel uses IP address spoofing so that the real address of the proxies is not revealed either to legitimate users or censors. We built a proof-of-concept prototype that uses encrypted VoIP for this downstream channel and demonstrated the feasibility of...

    A software program that searches and browses mission data emulates a Web browser, containing standard meta - phors for Web browsing. By taking advantage of back-end URLs, users may save and share search states. Also, since a Web interface is familiar to users, training time is reduced. Familiar back and forward buttons move through a local search history. A refresh/reload button regenerates a query, and loads in any new data. URLs can be constructed to save search results. Adding context to the current search is also handled through a familiar Web metaphor. The query is constructed by clicking on hyperlinks that represent new components to the search query. The selection of a link appears to the user as a page change; the choice of links changes to represent the updated search and the results are filtered by the new criteria. Selecting a navigation link changes the current query and also the URL that is associated with it. The back button can be used to return to the previous search state. This software is part of the MSLICE release, which was written in Java. It will run on any current Windows, Macintosh, or Linux system.

    2010-09-15

    Despite low environmental impact and high energy efficiency, electric vehicles (EV) have not been widely accepted. The lack of charging infrastructure is one reason. Since lithium-ion battery has high energy density and low internal resistance that allows quick charging, the convenience of EV may be greatly improved if charging infrastructure is prepared adequately. TEPCO aims for EV spread to reduce CO2 emissions and to increase demand for electric power, and has developed quick charging system for fleet-use EV to improve the convenience of EV. And based on research results, we will propose desirable characteristics of quick charger for public use.

    2005-08-01

    Full Text Available Abstract Background The AIDS and Cancer Specimen Resource (ACSR is an HIV/AIDS tissue bank consortium sponsored by the National Cancer Institute (NCI Division of Cancer Treatment and Diagnosis (DCTD. The ACSR offers to approved researchers HIV infected biologic samples and uninfected control tissues including tissue cores in micro-arrays (TMA accompanied by de-identified clinical data. Researchers interested in the type and quality of TMA tissue cores and the associated clinical data need an efficient method for viewing available TMA materials. Because each of the tissue samples within a TMA has separate data including a core tissue digital image and clinical data, an organized, standard approach to producing, navigating and publishing such data is necessary. The Association for Pathology Informatics (API extensible mark-up language (XML TMA data exchange specification (TMA DES proposed in April 2003 provides a common format for TMA data. Exporting TMA data into the proposed format offers an opportunity to implement the API TMA DES. Using our public BrowseTMA tool, we created a web site that organizes and cross references TMA lists, digital "virtual slide" images, TMA DES export data, linked legends and clinical details for researchers. Microsoft Excel® and Microsoft Word® are used to convert tabular clinical data and produce an XML file in the TMA DES format. The BrowseTMA tool contains Extensible Stylesheet Language Transformation (XSLT scripts that convert XML data into Hyper-Text Mark-up Language (HTML web pages with hyperlinks automatically added to allow rapid navigation. Results Block lists, virtual slide images, legends, clinical details and exports have been placed on the ACSR web site for 14 blocks with 1623 cores of 2.0, 1.0 and 0.6 mm sizes. Our virtual microscope can be used to view and annotate these TMA images. Researchers can readily navigate from TMA block lists to TMA legends and to clinical details for a selected tissue core

  1. Secure User Authentication using Sclera in Quick Response Codes

    2013-10-01

    Full Text Available In this paper, an authentication method using sclera embedded in Quick Response codes is proposed. Quick response codes are two dimensional barcodes which can hold more data and can be fastly readable by Personal computers and Handheld devices like mobile phones, smart phones and tablet PCs. Biometrics though noted for their accuracy suffer from the innate disadvantage of time consumption during enrolment and verification process. Together Biometrics and QR codes will provide a fast authentication system. This approach will be suitable for mobile ticketing applications. Cancelable sclera templates have been embedded in Quick Response codes and used for two factor authentication. The proposed Cancelable sclera template embedded in Quick response codes approach was evaluated using publicly available UBIRIS and IUPUI multi wavelength database. The experimental results show that this technique is efficient and provides accurate identity verification than other biometric traits.

  5. Trends in feed supply of three browse species in a semi-arid environment of Nigeria

    International Nuclear Information System (INIS)

    The feed supply trends of three important browse species, Anogeissus leiocarpus, Balanites aegyptiaca and Sclerocarya birrea was monitored in the Zamfara reserve of north-western Nigeria (6 deg. 45' - 7 deg. 10' E and 12 deg. 00' - 13 deg. 10'N), between peak period of production (September) and peak period of the dry season (April). 36 trees, 12 of each species were randomly selected and marked on a 3000 x 500 m transect. On each tree 12 twigs of one centimeter diameter thick were randomly selected and their leaves harvested and weighed fresh. After weighing, samples from each species were thoroughly mixed and 100 g sub samples were collected for oven drying and dry matter (DM) determination. This procedure was repeated at an interval of five weeks between 2002 and 2003. The experiment was laid as a Randomized Complete Block Design. Data were subjected to analysis of variance (ANOVA), where there were significant differences between treatment means, Duncan Multiple Range Test method was used for comparison. Results were presented of the DM production of the different browse species at the different time intervals. Anogeissus leiocarpus produced the highest (P < 0.001) amount of DM at all the periods, except in the month of March. Dry matter yield of the specie declined progressively from September (33.0 g) to March (9.0 g). Dry matter yield of Balanites aegyptiaca and Sclerocarya birrea was not consistent throughout the study period, however the former produced more yield (P < 0.001) than the latter (13.3 vs. 8.4 g, respectively). In the month of March, Sclerocarya birrea produced no leaves at all. On the overall, the mean DM yield of all the species was highest in November (23.3g) and lowest in March (6.3 g). The decline in the DM yield of all the species during this period could be due to physiological stress resulting from lack of moisture. It could also be due to competition of the grazing animals that switch from grazing to browsing during this period, which

  6. The transfer of fallout cesium-137 from browse to moose. Part 1

    International Nuclear Information System (INIS)

    We are investigating the transfer of fallout cesium-137 from soil to browse to moose (Alces alces) to wolf (Canis lupis) to promote our understanding of the movement of radionuclides through natural food chains. The first part of this study is concerned with moose food habits. Early winter food habits of moose from Hecla Island and Manitoba Game Hunting Area 26 in south central and south eastern Manitoba were studied. In 86 rumen samples, 25 food types were identified. Three methods of food habit determination were used: (1) percentage occurrence of food types, (2) subjective abundance scores and (3) percentage dry weight. All three methods yielded very similar results

    Full Text Available Objective – To explore how Web-savvy users think about and search an online catalogue. Design – Protocol analysis study. Setting – Academic library (Pennsylvania State University Libraries. Subjects – Eighteen users (17 students, 1 faculty member of an online public access catalog, divided into two groups of nine first-time and nine experienced users. Method – The study team developed five tasks that represented a range of activities commonly performed by library users, such as searching for a specific item, identifying a library location, and requesting a copy. Seventeen students and one faculty member, divided evenly between novice and experienced searchers, were recruited to “think aloud” through the performance of the tasks. Data were gathered through audio recordings, screen capture software, and investigator notes. The time taken for each task was recorded, and investigators rated task completion as “successful,” “partially successful,” “fail,” or “search aborted.” After the searching session, participants were interviewed to clarify their actions and provide further commentary on the catalogue search. Main results – Participants in both test groups were relatively unsophisticated subject searchers. They made minimal use of Boolean operators, and tended not to repair failed searches by rethinking the search vocabulary and using synonyms. Participants did not have a strong understanding of library catalogue contents or structure and showed little curiosity in developing an understanding of how to utilize the catalogue. Novice users were impatient both in choosing search options and in evaluating their search results. They assumed search results were sorted by relevance, and thus would not typically browse past the initial screen. They quickly followed links, fearlessly tried different searches and options, and rapidly abandoned false trails. Experienced users were more effective and efficient searchers than

  8. Enhancing Web Search with Semantic Identification of User Preferences

    Full Text Available Personalized web search is able to satisfy individuals information needs by modeling long-term and short-term user interests based on user actions, browsed documents or past queries and incorporate these in the search process. In this paper, we propose a personalized search approach which models the user search preferences in an ontological user profile and semantically compares this model against user current query context to re-rank search results. Our user profile is based on the predefined ontology Open Directory Project (ODP so that after a user's search, relevant web pages are classified into topics in the ontology using semantic and cosine similarity measures. Moreover, interest scores are assigned to topics based on the users ongoing behavior. Our experiments show that re-ranking based on the semantic evidence of the updated user profile efficiently satisfies user information needs with the most relevant results being brought on to the top of the returned results.

    The new digital revolution of big data is deeply changing our capability of understanding society and forecasting the outcome of many social and economic systems. Unfortunately, information can be very heterogeneous in the importance, relevance, and surprise it conveys, affecting severely the predictive power of semantic and statistical methods. Here we show that the aggregation of web users' behavior can be elicited to overcome this problem in a hard to predict complex system, namely the financial market. Specifically, our in-sample analysis shows that the combined use of sentiment analysis of news and browsing activity of users of Yahoo! Finance greatly helps forecasting intra-day and daily price changes of a set of 100 highly capitalized US stocks traded in the period 2012-2013. Sentiment analysis or browsing activity when taken alone have very small or no predictive power. Conversely, when considering a news signal where in a given time interval we compute the average sentiment of the clicked news, weighted by the number of clicks, we show that for nearly 50% of the companies such signal Granger-causes hourly price returns. Our result indicates a "wisdom-of-the-crowd" effect that allows to exploit users' activity to identify and weigh properly the relevant and surprising news, enhancing considerably the forecasting power of the news sentiment.

    1995-03-01

    Historically, Multimedia Video-on-Demand (VOD) systems have considered stream indexing as an authoring activity, decomposing monolithic streams containing no explicit indexing information. This paper suggests a scheme for 'up-front,' capture-time indexing of digital video streams, whereby the indexing information logically becomes part of the stream. This approach takes advantage of the sequential, temporal nature of capture and the knowledge of the stream recorder to empower further manipulation and playout of the stream. We explore the impact of capture-time indices, and implement a sample format in a Segment Definition File (SDF). The Video Broadcast Authoring Tool (VBAT) is the focus of our paper. Taking a video stream and an SDF as input, VBAT provides a means for authors to create, delete, modify and annotate segments of that stream. VBAT also integrates existing technology such as World-Wide Web's HTTP links and the Motion Picture Parser application. Creation of various-format stills for browsing is supported. VBAT provides for post-processing of the SDF to various playout environments; we implement and describe a postprocessor for World-Wide Web browsing and playout. Finally, we discuss VBAT's position in an integrated digital video broadcast environment and areas of future work.

    The actual development of distributed information technologies and Java programming enables employing them also in the medical arena to support the retrieval, integration and evaluation of heterogeneous data and multimodal images in a web browser environment. With this aim, we used them to implement a client-server architecture based on software agents. The client side is a Java applet running in a web browser and providing a friendly medical user interface to browse and visualize different patient and medical test data, integrating them properly. The server side manages secure connections and queries to heterogeneous remote databases and file systems containing patient personal and clinical data. Based on the Java Advanced Imaging API, processing and analysis tools were developed to support the evaluation of remotely retrieved bioimages through the quantification of their features in different regions of interest. The Java platform-independence allows the centralized management of the implemented prototype and its deployment to each site where an intranet or internet connection is available. Giving healthcare providers effective support for comprehensively browsing, visualizing and evaluating medical images and records located in different remote repositories, the developed prototype can represent an important aid in providing more efficient diagnoses and medical treatments.

  14. Scaling the effects of moose browsing on forage distribution, from the geometry of plant canopies to landscapes

    2009-01-01

    Landscape heterogeneity influences large herbivores by altering their feeding rates, but as herbivores attempt to maximize feeding rates they also create spatial heterogeneity by altering plant growth. Herbivore feeding rates thus provide a quantitative link between the causes and consequences of spatial heterogeneity in herbivore-dominated ecosystems. The fractal geometry of plant canopies determines both the density and mass of twigs available to foraging herbivores. These properties determine a threshold distance between plants (d*) that distinguishes the mechanisms regulating herbivore intake rates. When d* is greater than the actual distance between plants (d), intake is regulated by the rate of food processing in the mouth. But when d* plants. Alterations to plant geometry due to past browsing could change the rate at which herbivores encounter and process bites of plant tissue, modify d* relative to d, and thus change intake rates and the distribution of mechanisms regulating it across landscapes. We measured changes in the geometry of aspen (Populus tremuloides) and balsam fir (Abies balsamea) saplings along gradients of moose browsing from 2001 to 2005 at Isle Royale National Park, Michigan, USA. For aspen saplings, fractal dimension of bite density, bite mass, and forage biomass responded quadratically to increasing moose browsing and were greatest at -3-4 g-g.m-2.yr"1 consumption. For balsam fir, in contrast, these same measures declined steadily with increasing moose browsing. The different responses of plant canopies to increased browsing altered d* around plants. In summer, d* > d for aspen saplings at all prior consumption levels. Food processing therefore regulated summer moose feeding rates across our landscapes. In winter, changes in bite mass due to past browsing were sufficient to cause d* plant canopies can determine intake rate at larger spatial scales by changing d* relative to d and, hence, which mechanisms determine intake rate, essentially

    NAS uses PBS Professional to schedule and manage the workload on Pleiades, an 11,000+ node 1B cluster. At this scale the user experience for quick-turnaround jobs can degrade, which led NAS initially to set up two separate PBS servers, each dedicated to a particular workload. Recently we have employed PBS hooks and scheduler modifications to merge these workloads together under one PBS server, delivering sub-1-minute start times for the quick-turnaround workload, and enabling dynamic management of the resources set aside for that workload.

As a consequence, in Italy as well as in other European countries, situations with high ungulate density and, then, negative effects on the stability and dynamics of ecosystems, are increasing frequently. Starting from these evidences we investigated the effects of roe deer population on the vegetative regeneration of two different broadleaved tree species: Turkey oak (Quercus cerris L. and chestnut (Castanea sativa Mill. coppice stands. In Alpe di Catenaia (Apennines – Central Italy, after coppicing in 2002, we chose six experimental areas where fenced (P and non-fenced (NP plots were established. Measurements were performed at the beginning of the study period and in winter 2008 in both P and NP plots. Diameter and    height of all sprouts were measured. Results showed a different impact of roe deer on the two species. After seven years chestnut did not show any significant browsing-related damage, while in Turkey oak heavy differences between protected and non-protected areas are present: in NP plots roe deer browsing has produced a significant reduction in basal area (58% and volume (57% compared to P plots. The results agree with previous studies and confirm: (a a selective browsing pressure on Turkey oak; (b the lasting effect of the early impact after clear cutting, visible even seven years after. Based on the findings, we discussed the need for an integrated management of forest vegetation and forest fauna which should define the density of ungulates not only according to the theoretical carrying capacity    of ecosystems, but also considering (i the preservation of the ecosystem overall functionality, (ii the forest structure development and (iii the forest management type. st1\\:*{behavior:url(#ieooui } /* Style Definitions */ table.MsoNormalTable {mso

    Giunchiglia, Fausto; Kharkevich, Uladzimir; Zaihrayeu, Ilya

    2008-01-01

    In this paper we present a novel approach, called Concept Search, which extends syntactic search, i.e., search based on the computation of string similarity between words, with semantic search, i.e., search based on the computation of semantic relations between concepts. The key idea of Concept Search is to operate on complex concepts and to maximally exploit the semantic information available, reducing to syntactic search only when necessary, i.e., when no semantic information is available. ...

    2004-04-30

    We have developed a tool, named "SCOPExplorer", for browsing and analyzing SCOP information. SCOPExplorer 1) contains a tree-style viewer to display an overview of protein structure data, 2) is able to employ a variety of options to analyze SCOP data statistically, and 3) provides a function to link protein domains to protein data bank (PDB) resources. SCOPExplorer uses an XML-based structural document format, named "SCOPML", derived from the SCOP data. To evaluate SCOPExplorer, proteins containing more than 20 domains were analyzed. The Skp1-Skp2 protein complex and the Fab fragment of IgG2 contain the largest numbers of domains in the current eukaryotic SCOP database. These proteins are known to either bind to various proteins or generate diversity. This suggests that the more domains a protein has, the more interactions or more variability it will be capable of.

    2007-01-01

    The social media site Flickr allows users to upload their photos, annotate them with tags, submit them to groups, and also to form social networks by adding other users as contacts. Flickr offers multiple ways of browsing or searching it. One option is tag search, which returns all images tagged with a specific keyword. If the keyword is ambiguous, e.g., ``beetle'' could mean an insect or a car, tag search results will include many images that are not relevant to the sense the user had in mind when executing the query. We claim that users express their photography interests through the metadata they add in the form of contacts and image annotations. We show how to exploit this metadata to personalize search results for the user, thereby improving search performance. First, we show that we can significantly improve search precision by filtering tag search results by user's contacts or a larger social network that includes those contact's contacts. Secondly, we describe a probabilistic model that takes advantag...

    2012-11-01

    Many wild browse and bush species are undervalued mainly because of insufficient knowledge about their potential feeding value. The objective was to evaluate some nutritional attributes of various Algerian browse and shub species (Atriplex halimus, Artemisia campestris, Artemisia herba-alba, Astragalus gombiformis, Calobota saharae, Retama raetam, Stipagrostis pungens, Lygeum spartum and Stipa tenacissima). Chemical composition, phenols and tannins concentration, in vitro digestibility, in vitro gas production kinetics and in vitro bio-assay for assessment of tannins using buffered rumen fluid, and in situ disappearence of the edible parts of the plants (leaves, thin twigs and flowers) were determined. In general, protein content in dicotyledon species was always greater than in monocotyledon grasses, these showing higher neutral and acid detergent fibre and lower lignin contents than dicots. The tannin concentrations varied considerably between species, but in general the plants investigated in this study had low tannin contents (except for Artemisia spp. and S. tenacissima). Monocots showed lower in vitro and in situ digestibilities, fermentation rate, cumulative gas production and extent of degradation than dicot species. The plants were clustered by principal components analysis in two groups: poor-quality grasses and the most digestible dicot species. Chemical composition (neutral detergent fibre and protein) and digestibility were the main influential variables determining the ranking. In conclusion, A. halimus, A. campestris, A. herba-alba and A. gombiformis can be considered of greater nutritional value than the highly fibrous and low digestible grasses (S. pungens, L. spartum and S. tenacissima) that should be considered emergency roughages.

    Primates self-medicate to alleviate symptoms caused by gastro-intestinal nematodes (GIN) by consuming plants that contain secondary compounds. Would goats display the same dietary acumen? Circumstantial evidence suggests they could: goats in Mediterranean rangelands containing a shrub - Pistacia lentiscus - with known anthelmintic properties consume significant amounts of the shrub, particularly in the fall when the probability of being infected with GIN is greatest, even though its tannins impair protein metabolism and deter herbivory. In order to test rigorously the self-medication hypothesis in goats, we conducted a controlled study using 21 GIN-infected and 23 non-infected goats exposed to browse foliage from P. lentiscus, another browse species - Phillyrea latifolia, or hay during the build-up of infection. GIN-infected goats showed clear symptoms of infection, which was alleviated by P. lentiscus foliage but ingesting P. lentiscus had a detrimental effect on protein metabolism in the absence of disease. When given a choice between P. lentiscus and hay, infected goats of the Mamber breed showed higher preference for P. lentiscus than non-infected counterparts, in particular if they had been exposed to Phillyrea latifolia before. This was not found in Damascus goats. Damascus goats, which exhibit higher propensity to consume P. lentiscus may use it as a drug prophylactically, whereas Mamber goats, which are more reluctant to ingest it, select P. lentiscus foliage therapeutically. These results hint at subtle trade-offs between the roles of P. lentiscus as a food, a toxin and a medicine. This is the first evidence of self-medication in goats under controlled conditions. Endorsing the concept of self-medication could greatly modify the current paradigm of veterinary parasitology whereby man decides when and how to treat GIN-infected animals, and result in transferring this decision to the animals themselves.

  2. Contrasting responses of web-building spiders to deer browsing among habitats and feeding guilds.

    We examined web-building spider species richness and abundance in forests across a deer density gradient to determine the effects of sika deer browsing on spiders among habitats and feeding guilds. Deer decreased the abundance of web-building spiders in understory vegetation but increased their abundance in the litter layer. Deer seemed to affect web-building spiders in the understory vegetation by reducing the number of sites for webs because vegetation complexity was positively correlated with spider density and negatively correlated with deer density. In contrast, the presence of vegetation just above the litter layer decreased the spider density, and deer exerted a negative effect on this vegetation, possibly resulting in an indirect positive effect on spider density. The vegetation just above the litter layer may be unsuitable as a scaffold for building webs if it is too flexible to serve as a reliable web support, and may even hinder spiders from building webs on litter. Alternatively, the negative effect of this vegetation on spiders in the litter may be as a result of reduced local prey availability under the leaves because of the reduced accessibility of aerial insects. The response to deer browsing on web-building spiders that inhabit the understory vegetation varied with feeding guild. Deer tended to affect web-invading spiders, which inhabit the webs of other spiders and steal prey, more heavily than other web-building spiders, probably because of the accumulated effects of habitat fragmentation through the trophic levels. Thus, the treatment of a particular higher-order taxon as a homogeneous group could result in misleading conclusions about the effects of mammalian herbivores. PMID:18801259

  3. Object tracking and creation of linking information for distributed movie-based web-browsing system

    1998-12-01

    This paper proposes a new approach to automatically extract an accurate object from video streams. The new approach provides a useful tool creating linking information for a distributed movie-based Web-browsing system, and consists of a skip- labeling algorithm for feature-based segmentation, and a shrink-merge tracking algorithm for tracking an object. This skip-labeling algorithm can be used to segment an image into integrated regions of the same feature. The segmented regions belong to such a texture area as waves or forest. The shrink- merge tracking algorithm is executed, based on the time continuity of moving-objects, using morphological image processing, such as dilation and erosion. The dilation and erosion are repeatedly executed using the projection processing in which the object area in a next frame is derived from the object area in a current frame. The shrink-merge tracking algorithm can also project the area of a rotating- object in a current frame on the rotating-object containing the newly appearing regions in the next frame. The newly automated object extraction method works satisfactorily for the objects which move non-linearly within the video streams including MPEG and Motion JPEG, and works satisfactorily in approximately 450 frames, each with a full frame size of 704 X 480 pixels at video frame rate of 30 fps. This paper finally demonstrates that object-based linking information for a movie-based Web-browsing system contains information of objects obtained by the fully automated extraction from video- streams.

  4. Feeding characteristics reveal functional distinctions among browsing herbivorous fishes on coral reefs

    Streit, Robert P.; Hoey, Andrew S.; Bellwood, David R.

    2015-12-01

    The removal of macroalgal biomass by fishes is a key process on coral reefs. Numerous studies have identified the fish species responsible for removing mature macroalgae, and have identified how this varies spatially, temporally, and among different algal types. None, however, have considered the behavioural and morphological traits of the browsing fishes and how this may influence the removal of macroalgal material. Using video observations of fish feeding on the brown macroalga Sargassum polycystum, we quantified the feeding behaviour and morphology of the four dominant browsing species on the Great Barrier Reef ( Kyphosus vaigiensis, Naso unicornis, Siganus canaliculatus, and Siganus doliatus). The greatest distinction between species was the algal material they targeted. K. vaigiensis and N. unicornis bit on the entire macroalgal thallus in approximately 90 % of bites. In contrast, Si. canaliculatus and Si. doliatus avoided biting the stalks, with 80-98 % of bites being on the macroalgal leaves only. This distinctive grouping into `entire thallus-biters' versus `leaf-biters' was not supported by size-standardized measures of biting morphology. Rather, species-specific adult body sizes, tooth shape, and feeding behaviour appear to underpin this functional distinction, with adults of the two larger fish species ( N. unicornis and K. vaigiensis) eating the entire macroalgal thallus, while the two smaller species ( Si. canaliculatus and Si. doliatus) bite only leaves. These findings caution against assumed homogeneity within this, and potentially other, functional groups on coral reefs. As functional redundancy within the macroalgal browsers is limited, the smaller `leaf-biting' species are unlikely to be able to compensate functionally for the loss of larger `entire thallus-biting' species.

    Full Text Available The study aimed at investigating the impact of wild fires on browse availability on a thornveld vegetation woody plant community through its effects on woody plant structure and composition. Data was collected from four randomly selected paddocks at Mahiye a thornveld farm affected by annual wildfire outbreaks since 2000. A Point Centre Quarter technique on line transects was used to collect the data. Records taken from the nearest woody plant (≥ 0.3 m in each quarter was the woody species name, circumference at 30 cm height from the ground and distance from the point to that woody plant. Fifteen woody plant species were present in the study area with Acacia species being the most dominant. Out of the six hundred woody plants sampled, Acacia nilotica contributed 65%, Acacia karoo 10.8% and Acacia robusta 10.7% with the remainder contributed by the other twelve woody plants. A Kruskal-Wallis non-parametric test could not find provides sufficient evidence that the woody plant community structure was homogenous. The height and the diameter structure had a significant variation (P < 0.05 due to the presence of tall and large woody plants (height < 6m and diameter < 12 cm within the community. Nevertheless, the Lorenz curves depicted less inequality in the height and diameter distribution within the farm (Gini coefficient 0.242 and 0.266 respectively indicating dominance of a cohort. More than 75% of the recorded stems are greater than 2.4 m high and had a diameter of greater than 8 cm. According to the results, the plant community had high quality browse species but the dominant size compromised accessibility of the browse. Therefore, frequent wildfires reduce browse availability in thornveld rangelands. Further research is required to unveil the amount of unavailable browse.

  8. Effectiveness of fencing and hunting to control Lama guanicoe browsing damage: Implications for Nothofagus pumilio regeneration in harvested forests.

    Browsing damage by native ungulates is often to be considered one of the reasons of regeneration failure in Nothofagus pumilio silvicultural systems. Fencing and hunting in forests at regeneration phase have been proposed to mitigate browsing effects. This study aims to determine effectiveness of these control methods in harvested forests, evaluating browsing damage over regeneration, as well as climate-related constraints (freezing or desiccation). Forest structure and regeneration plots were established in two exclosures against native ungulates (Lama guanicoe) by wire fences in the Chilean portion of Tierra del Fuego island, where tree regeneration density, growth, abiotic damage and quality (multi-stems and base/stem deformation) were assessed. Exclosures did not influence regeneration density (at the initial stage with 1.3 m high). However, sapling height at 10-years old was significantly lower outside (40-50 cm high) than inside exclosures (80-100 cm), and also increased their annual height growth, probably as a hunting effect. Likewise, quality was better inside exclosures. Alongside browsing, abiotic conditions negatively influenced sapling quality in the regeneration phase (20%-28% of all seedlings), but greatly to taller plants (as those from inside exclosure). This highlights the importance of considering climatic factors when analysing browsing effects. For best results, control of guanaco in recently harvested areas by fencing should be applied in combination with a reduction of guanaco density through continuous hunting. The benefits of mitigation actions (fencing and hunting) on regeneration growth may shorten the regeneration phase period in shelterwood cutting forests (30-50% less time), but incremental costs must be analysed in the framework of management planning by means of long-term studies.

    Gardi, Frédéric; Darlay, Julien; Estellon, Bertrand; Megel, Romain

    2014-01-01

    This book covers local search for combinatorial optimization and its extension to mixed-variable optimization. Although not yet understood from the theoretical point of view, local search is the paradigm of choice for tackling large-scale real-life optimization problems. Today's end-users demand interactivity with decision support systems. For optimization software, this means obtaining good-quality solutions quickly. Fast iterative improvement methods, like local search, are suited to satisfying such needs. Here the authors show local search in a new light, in particular presenting a new kind of mathematical programming solver, namely LocalSolver, based on neighborhood search. First, an iconoclast methodology is presented to design and engineer local search algorithms. The authors' concern about industrializing local search approaches is of particular interest for practitioners. This methodology is applied to solve two industrial problems with high economic stakes. Software based on local search induces ex...

  13. Drive of especially quick-acting valve for nuclear power

    International Nuclear Information System (INIS)

    The quick-acting valve drive consists of two branches coupled via a control joint, with their outer ends fitted in fixing joints. The active end of a flexible control element is connected to the control joint. In normal operation, the valve piston is in the terminal position. The flexible element is compressed and retained in the position by air pressure. If the valve is to be closed, compressed air is supplied in a control cylinder from the other side. In the event of air supply failure, the compressed air kept in the valve body can be used for several settings. When the supply is exhausted, the flexible element can be used for emergency valve closing. The device allows achieving high control forces of quick-acting valves in emergencies while keeping down the size of the device and featuring low consumption of compressed air at normal operation.

    A major challenge for remote sensing science researchers is searching and acquiring relevant data files for their research projects based on content, space and time constraints. Several structured query (SQ) and hierarchical navigation (HN) search interfaces have been develop ed to satisfy this requirement, yet the dominant search engines in th e general domain are based on free-text search. The Goddard Earth Sci ences Data and Information Services Center has developed a free-text search interface named Mirador that supports space-time queries, inc luding a gazetteer and geophysical event gazetteer. In order to compe nsate for a slightly reduced search precision relative to SQ and HN t echniques, Mirador uses several search optimizations to return result s quickly. The quick response enables a more iterative search strateg y than is available with many SQ and HN techniques.

    Full Text Available  Web is a huge information repository covering almost every topic, in which a human user could be interested. As the size and richness of information on the web increases, diversity and complexity of the tasks users tries to perform also increases. With the overwhelming volume of information on the web, the task of finding relevant information related to a specific query or topic is becoming increasingly difficult. Now a day’s commonly used task on internet is web search. User gets variety of related information for their queries. To provide more relevant and effective results to user, Personalization technique is used. Personalized web search refer to search information that is tailored specifically to a person’s interests by incorporating information about query provided. Two general types of approaches to personalizing search results are modifying user’s query and re-ranking search results. Several personalized web search techniques based on web contents, web link structure, browsing history, user profiles and user queries. This paper is to represent survey on various techniques of personalization

  15. Evaluation of quick tests for phosphorus determination in dairy manures

    International Nuclear Information System (INIS)

    Nutrients in animal manure are valuable inputs in agronomic crop production. Rapid and timely information about manure nutrient content are needed to minimize the risks of phosphorus (P) over-application and losses of dissolved P (DP) in runoff from fields treated with manure. We evaluated the suitability of a commercial hand-held reflectometer, a hydrometer, and an electrical conductivity (EC) meter for determining DP and total P (TP) in dairy manures. Bulk samples (n = 107) collected from farms across CT, MD, NY, PA, and VA were highly variable in total solids (TS) concentration, ranging from 11 to 213 g L-1, in suspensions' pH (6.3-9.2), and EC (6.2-53.3 dS m-1). Manure DP concentrations measured using the RQFlex reflectometer (RQFlex-DPs) were related to molybdate-reactive P (MRPs) concentrations as follows: RQFlex-DPs = 0.471 x MRPs + 1102 (r2 = 0.29). Inclusion of pH and squared-pH terms improved the prediction of manure DP from RQFlex results (r2 = 0.66). Excluding five outlier samples that had pH ≤ 6.9 the coefficient of determination (r2) for the MRPs and RQFlex-DPs relationship was 0.83 for 95% of the samples. Manure TS were related to hydrometer specific gravity readings (r2 = 0.53) that were in turn related to TP (r2 = 0.34), but not to either RQFlex-DP or MRP. Relationships between suspensions' EC and DP or TP were non-significant. Therefore, the RQFlex method is the only viable option for on-site quick estimates of DP that can be made more robust when complemented with TS and pH measurements. The DP quick test can provide near real-time information on soluble manure nutrient content across a wide range of handling and storage conditions on dairy farms and quick estimates of potential soluble P losses in runoff following land applications of manure. - The dissolved phosphorous quick test can provide real-time information on soluble manure nutrient control

    Carrascal, Juan Pablo; Erramilli, Vijay; Cherubini, Mauro; de Oliveira, Rodrigo

    2011-01-01

    Most online services (Google, Facebook etc.) operate by providing a service to users for free, and in return they collect and monetize personal information (PI) of the users. This operational model is inherently economic, as the "good" being traded and monetized is PI. This model is coming under increased scrutiny as online services are moving to capture more PI of users, raising serious privacy concerns. However, little is known on how users valuate different types of PI while being online, as well as the perceptions of users with regards to exploitation of their PI by online service providers. In this paper, we study how users valuate different types of PI while being online, while capturing the context by relying on Experience Sampling. We were able to extract the monetary value that 168 participants put on different pieces of PI. We find that users value their PI related to their offline identities more (3 times) than their browsing behavior. Users also value information pertaining to financial transactio...

    Fire has been the dominant disturbance in boreal America since the Pleistocene, resulting in a spatial mosaic in which the most fire occurs in the continental northwest. Spatial variation in snowshoe hare (Lepus americanus) density reflects the fire mosaic. Because fire initiates secondary forest succession, a fire mosaic creates variation in the abundance of early successional plants that snowshoe hares eat in winter, leading to geographic variation in hare density. We hypothesize that fire is the template for a geographic mosaic of natural selection: where fire is greatest and hares are most abundant, hare browsing has most strongly selected juvenile-phase woody plants for defense. We tested the hypothesis at multiple spatial scales using Alaska birch (Betula neoalaskana) and white birch (Betula papyrifera). We also examined five alternative hypotheses for geographic variation in antibrowsing defense. The fire-hare-defense hypothesis was supported at transcontinental, regional, and local scales; alternative hypotheses were rejected. Our results link transcontinental variation in species interactions to an abiotic environmental driver, fire. Intakes of defense toxins by Alaskan hares exceed those by Wisconsin hares, suggesting that the proposed selection mosaic may coincide with a geographic mosaic of coevolution. PMID:19422319

  20. The use of interactive graphical maps for browsing medical/health Internet information resources

    2003-01-01

    Full Text Available Abstract As online information portals accumulate metadata descriptions of Web resources, it becomes necessary to develop effective ways for visualising and navigating the resultant huge metadata repositories as well as the different semantic relationships and attributes of described Web resources. Graphical maps provide a good method to visualise, understand and navigate a world that is too large and complex to be seen directly like the Web. Several examples of maps designed as a navigational aid for Web resources are presented in this review with an emphasis on maps of medical and health-related resources. The latter include HealthCyberMap maps http://healthcybermap.semanticweb.org/, which can be classified as conceptual information space maps, and the very abstract and geometric Visual Net maps of PubMed http://map.net (for demos. Information resources can be also organised and navigated based on their geographic attributes. Some of the maps presented in this review use a Kohonen Self-Organising Map algorithm, and only HealthCyberMap uses a Geographic Information System to classify Web resource data and render the maps. Maps based on familiar metaphors taken from users' everyday life are much easier to understand. Associative and pictorial map icons that enable instant recognition and comprehension are preferred to geometric ones and are key to successful maps for browsing medical/health Internet information resources.

  1. Web architecture for the remote browsing and analysis of distributed medical images and data.

    Masseroli, M; Pinciroli, F

    2001-01-01

    To provide easy retrieval, integration and evaluation of multimodal medical images and data in a web browser environment, distributed application technologies and Java programming were used to develop a client-server architecture based on software agents. The server side manages secure connections and queries to heterogeneous remote databases and file systems containing patient personal and clinical data. The client side is a Java applet running in a web browser and providing a friendly medical user interface to perform queries on patient and medical test data and integrate and visualize properly the various query results. A set of tools based on Java Advanced Imaging API enables to process and analyze the retrieved bioimages, and quantify their features in different regions of interest. The platform-independence Java technology makes the developed prototype easy to be managed in a centralized form and provided in each site where an intranet or internet connection can be located. Giving the healthcare providers effective tools for browsing, querying, visualizing and evaluating comprehensively medical images and records in all locations where they can need them - e.g. emergency, operating theaters, ward, or even outpatient clinics- the implemented prototype represents an important aid in providing more efficient diagnoses and medical treatments.

    For the last decade planetariums have been adding capability of "full dome video" systems for both movie playback and interactive display. True scientific data visualization has now come to planetarium audiences as a means to display the actual three dimensional layout of the universe, the time based array of planets, minor bodies and spacecraft across the solar system, and now globe browsing systems to examine planetary bodies to the limits of resolutions acquired. Additionally, such planetarium facilities can be networked for simultaneous display across the world for wider audience and reach to authoritative scientist description and commentary. Data repositories such as NASA's Lunar Mapping and Modeling Project (LMMP), NASA GSFC's LANCE-MODIS, and others conforming to the Open Geospatial Consortium (OGC) standard of Web Map Server (WMS) protocols make geospatial data available for a growing number of dome supporting globe visualization systems. The immersive surround graphics of full dome video replicates our visual system creating authentic virtual scenes effectively placing audiences on location in some cases to other worlds only mapped robotically.

    Directory of Open Access Journals (Sweden)

    Ivan Komarov

    Full Text Available In this paper, we describe a new brute force algorithm for building the k-Nearest Neighbor Graph (k-NNG. The k-NNG algorithm has many applications in areas such as machine learning, bio-informatics, and clustering analysis. While there are very efficient algorithms for data of low dimensions, for high dimensional data the brute force search is the best algorithm. There are two main parts to the algorithm: the first part is finding the distances between the input vectors, which may be formulated as a matrix multiplication problem; the second is the selection of the k-NNs for each of the query vectors. For the second part, we describe a novel graphics processing unit (GPU-based multi-select algorithm based on quick sort. Our optimization makes clever use of warp voting functions available on the latest GPUs along with user-controlled cache. Benchmarks show significant improvement over state-of-the-art implementations of the k-NN search on GPUs.

    The Shielding Integral Benchmark Archive Database (SINBAD) Search Tool has been developed to serve as an interface with the SINBAD database to facilitate a simple and quick means of searching for information related to experimental benchmark problems. The Search Tool is written in Java and provides a better and efficient way to retrieve information from the SINBAD database. Searches can be performed quickly and easily. With regard to improvements, users are no longer required to know the name of the benchmarks to search the database. Instead, a search can be performed by specifying the experimental facility, constituents of the experimental benchmark, etc. In summary, a new powerful database search tool has been developed for SINBAD.

  6. Quick Mining of Isomorphic Exact Large Patterns from Large Graphs

    KAUST Repository

    Almasri, Islam

    2014-12-01

    The applications of the sub graph isomorphism search are growing with the growing number of areas that model their systems using graphs or networks. Specifically, many biological systems, such as protein interaction networks, molecular structures and protein contact maps, are modeled as graphs. The sub graph isomorphism search is concerned with finding all sub graphs that are isomorphic to a relevant query graph, the existence of such sub graphs can reflect on the characteristics of the modeled system. The most computationally expensive step in the search for isomorphic sub graphs is the backtracking algorithm that traverses the nodes of the target graph. In this paper, we propose a pruning approach that is inspired by the minimum remaining value heuristic that achieves greater scalability over large query and target graphs. Our testing on various biological networks shows that performance enhancement of our approach over existing state-of-the-art approaches varies between 6x and 53x. © 2014 IEEE.

  7. Winter browse selection by white-tailed deer and implications for bottomland forest restoration in the Upper Mississippi River Valley, USA

    Science.gov (United States)

    Cogger, Benjamin J.; De Jager, Nathan R.; Thomsen, Meredith; Adams, Carrie Reinhardt

    2014-01-01

    White-tailed deer (Odocoileus virginianus) forage selectively, modifying upland forest species composition and in some cases shifting ecosystems to alternative stable states. Few studies, however, have investigated plant selection by deer in bottomland forests. Herbaceous invasive species are common in wetlands and their expansion could be promoted if deer avoid them and preferentially feed on native woody species. We surveyed plant species composition and winter deer browsing in 14 floodplain forest restoration sites along the Upper Mississippi River and tributaries. Tree seedling density declined rapidly with increasing cover of invasive Phalaris arundinacea, averaging less than 1 per m2 in all sites in which the grass was present. Deer browsed ∼46% of available tree seedling stems (branches) at mainland restorations, compared to ∼3% at island sites. Across all tree species, the number of browsed stems increased linearly with the number available and responded unimodally to tree height. Maximum browsing rates were observed on trees with high stem abundances (>10 per plant) and of heights between 50 and 150 cm. Deer preferred Ulmus americana and Acer saccharinum, and avoided Fraxinus pennsylvanica, Acer negundo, and Quercus spp. at mainland sites, and did not browse Phalaris arundinacea if present. Depending on plant growth responses to herbivory and the competitive effects of unbrowsed species, our results suggest that selective foraging could promote the expansion of invasive species and/or alter tree species composition in bottomland forest restorations. Islands may, however, serve as refuges from browsing on a regional scale.

  8. Extensive browsing by a conventional grazer? Stable carbon isotope analysis reveals extraordinary dietary flexibility among Sanga cattle of North Central Namibia.

    2013-01-01

    Intraspecies dietary flexibility, such as variable consumption of graze vs. browse in herbivores, has received scant attention on a spatial scale despite growing evidence of substantial variability within and among populations, especially in bovids. Here, we report on extraordinary differences in cattle diet among two communal pasture areas across seasons in northern Namibia: King Nehale (KN, open grassland) and Okongo (OK, dense woodland). Percentage C3 browse and C4 grass consumption was determined from δ(13)C values of dung samples, using a Bayesian stable-isotope mixing model (SIAR - stable isotope analysis in R). During the wet and early dry season, KN cattle consumed 11 and 19% browse, respectively, and the OK cattle consumed 84% browse. At the end of the dry season, the browse intake of KN cattle increased to 33% while that of OK cattle decreased to 55%. Vegetation structure influenced the graze/browse consumption strongly in both areas. A better understanding of this extraordinary dietary flexibility is imperative as anthropogenically driven habitat change is projected to lead to the extinction of perceived grazing specialists.

  9. A comparison of woody browse selection by hand-raised, boma-adapted and wild black rhinoceros, Diceros bicornis, L. in Matusadona National Park, Zimbabwe

    Directory of Open Access Journals (Sweden)

    G. Matipano

    2003-12-01

    Full Text Available Differences in woody browse selection between hand-raised (and subsequently released, boma-adapted and wild black rhinoceros, Diceros bicornis, L. were studied in Matusadona National Park between December 1999 and July 2000. Boma-adapted rhinoceros were animals that were subjected to hand-raising and were kept in bomas (enclosures over night. The feeding behaviour was different between the three rhinoceros groups. All rhinoceros groups utilised and selected for a few browse species in common, at different preference levels in the same habitat types according to season. Wild rhinoceroses browsed most in Colophospermum-Terminalia-Combretum woodland in the wet season and in thicket in the dry season. Hand-raised rhinoceroses browsed most in Colophospermum-Terminalia-Combretum woodland and boma-adated rhinos in thickets in both the wet and the early dry seasons. Hand-raised and bomaadapted rhinos changed their habitats less for browse selection than wild rhinos. This can be ascribed to a relative restriction of home range in the hand-raised group and a herding effect for the boma-adapted animals. These situations might have accounted for differences in seasonal browse selection by the rhinoceros groups.

    In two experiments involving a total of 542 subjects, a series of slides depicting a burglary was shown. After the initial event, subjects were exposed to one or more narratives about the event that contained some misinformation or neutral information about four critical details. Finally, subjects were tested on their memories of what they saw, and their reaction times and confidence levels were measured. When subjects took a standard test in which the misinformation item was a possible response option, they responded very quickly and confidently when making this incorrect choice. Misled subjects responded as quickly and confidently to these "unreal" memories as they did to their genuine memories. It does not seem, then, that the misinformation effect arises from a large proportion of subjects who must resolve a conflict between two memories when they are tested, a conflict that would be expected to take time. When subjects took a modified test in which the misinformation item was not a possible response, misled subjects were as accurate as were controls, but they responded more slowly, regardless of whether they ultimately chose the right or wrong option. These findings indicate that misinformation does introduce some form of interference not detected by a simple test of accuracy. PMID:2796745

    Background: Diagnosis of spontaneous bacterial peritonitis in cirrhosis can be made when a patient has an ascites polymorphonuclear leukocyte count ≥250/mm3. However, symptomatic bacterascites, which is a variant of spontaneous bacterial peritonitis with signs of infection but an ascites polymorphonuclear leukocyte count <250/mm3, cannot be confirmed until the time-consuming ascites culture becomes positive. Currently, early indicators for symptomatic bacterascites remain undetermined. Aims: To develop a quick screening model for early detection of symptomatic bacterascites in cirrhosis. Materials and Methods: Data on patients with cirrhotic ascites from two hospitals (from 2010 to 2014) were collected retrospectively. Patients with symptomatic bacterascites were enrolled in the case group and compared with patients without any infection in the control group. Logistic regression analysis was used to build a model for screening symptomatic bacterascites, and a receiver operating characteristics curve was used to assess the model. Results: In total, 103 patients were enrolled in the case group and 204 patients were enrolled in the control group. A screening model was constructed based on body temperature, abdominal tenderness, blood neutrophil percentage, blood total bilirubin, prothrombin time, and ascites nucleated leukocyte count. The area under the receiver operating characteristic curve was 0.939; a screening score of 0.328 was the best cutoff value. Conclusion: Patients with suspected symptomatic bacterascites can be quickly screened according to the developed model, and a screening score ≥0.328 indicates symptomatic bacterascites.

    In the practices of cryobiology,selection of an optimum freeze/thawing program and an idealistic cryoprotective agent often requires rather tedious,time consuming and repetitive tests.Integrating the functions of sample preparation and viability detection,the concept of biochip technology was introduced to the field of cryopreservation,aiming at quickly finding an optimum freezing and thawing program.Prototype devices were fabricated and corresponding experimental tests were performed.It was shown that microflow-channel chip could not offer a high quality solution distribution.As an alternative,the spot-dropping chip proved to be an excellent way to load the sample quickly and reliably.Infrared thermal mapping on such a chip showed that it had a rather uniform heat transfer boundary.Applying the spot-dropping chip combined with the thermoelectric cooling device,the final output of cryopreservation of multiple samples was tested,and the optimal freeze/thawing program as well as the potentially best concentration of the cryoprotective agent was found by analyzing the results.Further,application of this technique to measure the thermo-physical properties of the cryo-protective agent was also investigated.The study demonstrated that a biochip with integrated automatic loading and inspection units opens the possibility of a massive optimization of the complex cryopreservation program in a quicker and more economical way.

  13. Quick analysis techniques for assay of radioactivity in urine

    International Nuclear Information System (INIS)

    The needs for bioassay has recently increased in the radiation protection management at the nuclear power plant. In the practical application of bioassay, it is desirable to simplify pre-treatment procedures and to delete chemical separation treatments before the radiation measurement with a low-background liquid scintillation system. This paper presents the results on accumulation of background data of radioactivities in urine and assessment of the availability of a quick analysis method for urine-bioassay. The major results obtained are as follows: (1) The background concentration of 3H in human urine, which varies in both time and persons, is 50 - 240 pCi/l and equivalent to those in natural water. (2) A small quantity of non-treatment urine of 2 ml is sufficient to estimate the 3H concentration over the screening level in monitoring of the internal radiation exposure. (3) The average concentrations of 40K and 137Cs in human urine measured with a Ge detector are 2500 and 8 pCi/l, respectively, and the ratio of 137Cs to K is 3.14 pCi/g, which is applicable to determination of abnormal intake of 137Cs. (4) A simplified bioassay method using the quick analysis technique for non-treatment urine is proposed for monitoring the internal radiation exposure at the nuclear power plant. (author)

    One important class of online videos is that of news broadcasts. Most news organisations provide near-immediate access to topical news broadcasts over the Internet, through RSS streams or podcasts. Until lately, technology has not made it possible for a user to automatically go to the smaller parts, within a longer broadcast, that might interest them. Recent advances in both speech recognition systems and natural language processing have led to a number of robust tools that allow us to provide users with quicker, more focussed access to relevant segments of one or more news broadcast videos. Here we present our new interface for browsing or searching news broadcasts (video/audio) that exploits these new language processing tools to (i) provide immediate access to topical passages within news broadcasts, (ii) browse news broadcasts by events as well as by people, places and organisations, (iii) perform cross lingual search of news broadcasts, (iv) search for news through a map interface, (v) browse news by tre...

    As the volume of electronically available information grows, relevant items become harder to find. This work presents an approach to personalizing search results in scientific publication databases. This work focuses on re-ranking search results from existing search engines like Solr or ElasticSearch. This work also includes the development of Obelix, a new recommendation system used to re-rank search results. The project was proposed and performed at CERN, using the scientific publications available on the CERN Document Server (CDS). This work experiments with re-ranking using offline and online evaluation of users and documents in CDS. The experiments conclude that the personalized search result outperform both latest first and word similarity in terms of click position in the search result for global search in CDS.

    2005-12-01

    The Unidata Internet Data Distribution (IDD) network delivers gigabytes of data per day in near real time to sites across the U.S. and beyond. The THREDDS Data Server (TDS) supports public browsing of metadata and data access via OPeNDAP enabled URLs for datasets such as these. With such large quantities of data, sites generally employ a simple data management policy, keeping the data for a relatively short term on the order of hours to perhaps a week or two. In order to save interesting data in longer term storage and make it available for sharing, a user must move the data herself. In this case the user is responsible for determining where space is available, executing the data movement, generating any desired metadata, and setting access control to enable sharing. This task sequence is generally based on execution of a sequence of low level operating system specific commands with significant user involvement. The LEAD (Linked Environments for Atmospheric Discovery) project is building a cyberinfrastructure to support research and education in mesoscale meteorology. LEAD orchestrations require large, robust, and reliable storage with speedy access to stage data and store both intermediate and final results. These requirements suggest storage solutions that involve distributed storage, replication, and interfacing to archival storage systems such as mass storage systems and tape or removable disks. LEAD requirements also include metadata generation and access in order to support querying. In support of both THREDDS and LEAD requirements, Unidata is designing and prototyping the THREDDS Data Repository (TDR), a framework for a modular data repository to support distributed data storage and retrieval using a variety of back end storage media and interchangeable software components. The TDR interface will provide high level abstractions for long term storage, controlled, fast and reliable access, and data movement capabilities via a variety of technologies such as

    Full Text Available Bone Cement is being widely used in vertebroplasty, a minimally invasive surgical procedure to treat spinal frac-tures and collapsed vertebrae. It is being labeled as a concrete success in medical field. It is being used to treat fractures due to osteoporosis, menopause, steroids, hyperthyroidism and chronic obstructive pulmonary diseases. In this technique a needle with bone cement (PMMA, polymethylmethacrylate is injected into the collapsed verte-bra after administering local anesthesia to patient. It solidifies within few minutes and provides support to damaged bone resulting in relief to the patient. It also prevents the movement between different parts of the broken bone. Hence it requires a short hospital stay for the patient and the procedure can be performed with much ease and at significant lower costs. Patient can resume normal activity within a day or so. Bone cement is now being referred to as the quick medical fix material for early repair of fractures.

  3. Report on JANNAF panel on shotgun/relative quickness testing

    Gould, R. A.

    1980-01-01

    As the need for more energetic solid propellants continues, a number of problems arises. One of these is the tendency of high energy propellants to transition from burning (deflagration) to detonation in regions where the propellant is present in small particle sizes; e.g., in case bonding areas of a motor after a rapid depressurization causes a shear zone at the bond interface as the stressed propellant and motor case relax at different rates. In an effort to determine the susceptibility of propellants to high strain rate break up (friability), and subsequent DDT, the propulsion community uses the shotgun/relative quickness test as one of a number of screening tests for new propellant formulations. Efforts to standardize test techniques and equipment are described.

    Ungulates often adjust their diet when food availability varies over time. However, it is poorly understood when and to what extent individuals change their diet and, if they do so, if all individuals of a population occupy distinct or similar dietary niches. In the arid Namibian Kunene Region, we studied temporal variations of individual niches in grazing gemsbok (Oryx gazella gazella) and predominantly browsing springbok (Antidorcas marsupialis). We used variation in stable C and N isotope ratios of tail hair increments as proxies to estimate individual isotopic dietary niches and their temporal plasticity. Isotopic dietary niches of populations of the two species were mutually exclusive, but similar in breadth. Isotopic niche breadth of gemsbok was better explained by within-individual variation than by between-individual variation of stable isotope ratios, indicating that gemsbok individuals were facultative specialists in using isotopically distinct local food resources. In contrast, inter- and intra-individual variations contributed similarly to the isotopic niche breadth of the springbok population, suggesting a higher degree of individual isotopic segregation in a more generalist ungulate. In both species, between-individual variation was neither explained by changes in plant primary productivity, sex, geographical position nor by group size. Within species, individual dietary niches overlapped partially, suggesting that both populations included individuals with distinct isotopic dietary niches. Our study provides the first evidence for isotopic dietary niche segregation in individuals of two distinct desert ungulates. Similar, yet isotopically distinct dietary niches of individuals may facilitate partitioning of food resources and thus individual survival in desert ecosystems. PMID:25953117

    2015-07-01

    Proteins evolve by mutations and natural selection. The network of sequence similarities is a rich source for mining homologous relationships that inform on protein structure and function. There are many servers available to browse the network of homology relationships but one has to wait up to a minute for results. The SANSparallel webserver provides protein sequence database searches with immediate response and professional alignment visualization by third-party software. The output is a list, pairwise alignment or stacked alignment of sequence-similar proteins from Uniprot, UniRef90/50, Swissprot or Protein Data Bank. The stacked alignments are viewed in Jalview or as sequence logos. The database search uses the suffix array neighborhood search (SANS) method, which has been re-implemented as a client-server, improved and parallelized. The method is extremely fast and as sensitive as BLAST above 50% sequence identity. Benchmarks show that the method is highly competitive compared to previously published fast database search programs: UBLAST, DIAMOND, LAST, LAMBDA, RAPSEARCH2 and BLAT. The web server can be accessed interactively or programmatically at http://ekhidna2.biocenter.helsinki.fi/cgi-bin/sans/sans.cgi. It can be used to make protein functional annotation pipelines more efficient, and it is useful in interactive exploration of the detailed evidence supporting the annotation of particular proteins of interest.

    Full Text Available This paper presents a novel framework for Visual Exploratory Search of Relationship Graphs on Smartphones (VESRGS that is composed of three major components: inference and representation of semantic relationship graphs on the Web via meta-search, visual exploratory search of relationship graphs through both querying and browsing strategies, and human-computer interactions via the multi-touch interface and mobile Internet on smartphones. In comparison with traditional lookup search methodologies, the proposed VESRGS system is characterized with the following perceived advantages. 1 It infers rich semantic relationships between the querying keywords and other related concepts from large-scale meta-search results from Google, Yahoo! and Bing search engines, and represents semantic relationships via graphs; 2 the exploratory search approach empowers users to naturally and effectively explore, adventure and discover knowledge in a rich information world of interlinked relationship graphs in a personalized fashion; 3 it effectively takes the advantages of smartphones' user-friendly interfaces and ubiquitous Internet connection and portability. Our extensive experimental results have demonstrated that the VESRGS framework can significantly improve the users' capability of seeking the most relevant relationship information to their own specific needs. We envision that the VESRGS framework can be a starting point for future exploration of novel, effective search strategies in the mobile Internet era.

    Full Text Available These days we are using some popular web search engines for information retrieval in all areas, such engine are as Google, Yahoo!, and Live Search, etc. to obtain initial helpful information.Which information we retrieved via search engine may not be relevant to the search target in the search engine user's mind. When user not found relevant information he has to shortlist the results. Thesesearch engines use traditional search service based on "static keywords", which require the users to type in the exact keywords. This approach clearly puts the users in a critical situation of guessing the exact keyword. The users may want to define their search by using attributes of the search target. But the relevancy of results in most cases may not be satisfactory and the users may not be patient enough to browse through complete list of pages to get a relevant result. The reason behind this is the search engines performs search based on the syntax not on semantics. But they seemed to be less efficient to understand the relationship between the keywords which had an adverse effect on the results it produced. Semantic search engines – only solution to this; which returns concepts not documents according to user query matching. In This paper we proposed a semantic query interface which creates a semantic query according the user input query and study of current semantic search engine techniques for semantic search.

    Full Text Available This paper proposed a quick, affine invariance matching method for oblique images. It calculated the initial affine matrix by making full use of the two estimated camera axis orientation parameters of an oblique image, then recovered the oblique image to a rectified image by doing the inverse affine transform, and left over by the SIFT method. We used the nearest neighbor distance ratio(NNDR, normalized cross correlation(NCC measure constraints and consistency check to get the coarse matches, then used RANSAC method to calculate the fundamental matrix and the homography matrix. And we got the matches that they were interior points when calculating the homography matrix, then calculated the average value of the matches' principal direction differences. During the matching process, we got the initial matching features by the nearest neighbor(NN matching strategy, then used the epipolar constrains, homography constrains, NCC measure constrains and consistency check of the initial matches' principal direction differences with the calculated average value of the interior matches' principal direction differences to eliminate false matches. Experiments conducted on three pairs of typical oblique images demonstrate that our method takes about the same time as SIFT to match a pair of oblique images with a plenty of corresponding points distributed evenly and an extremely low mismatching rate.

  15. Study on quick screening of nuclear power plant events

    International Nuclear Information System (INIS)

    Operation safety surveillance and operation experience feedback are two effective measures to ensure and improve nuclear safety, the basis of which is nuclear power plant events analysis. A substantial number of events occur every year in nuclear power plant, thus screening for safety important and typical events which are valuable for experience feedback is important. Combining with risk insights, a new method for quick screening of nuclear power plant events is proposed on the basis of present event analysis method. A risk assessment tool to support the new method, i. e. significance determination process (SDP), is introduced in details. An example event is analyzed to obtain ΔCDF using SDP software and PSA model respectively, to verify the capability of SDP. The quantification results show agreement between ΔCDF of SDP and PSA models. It is concluded that the quantification results of SDP are capable for applications it supports. Limitations of present SDP software are pointed out and its future extension and potential applications are discussed. (authors)

    International Nuclear Information System (INIS)

    Testing a single hardware unit of an accelerator control system often requires the setup of a program with graphical user interface. Developing a dedicated application for a specific hardware unit test could be time consuming and the application may become obsolete after the unit tests. This paper documents a methodology for quick design and setup of an interface focused on performing unit tests of accelerator equipment with minimum programming work. The method has three components. The first is a generic accelerator device object (ADO) manager which can be used to setup, store, and log testing controls parameters for any unit testing system. The second involves the design of a TAPE (Tool for Automated Procedure Execution) sequence file that specifies and implements all te testing and control logic. The sting third is the design of a PET (parameter editing tool) page that provides the unit tester with all the necessary control parameters required for testing. This approach has been used for testing the horizontal plane of the Stochastic Cooling Motion Control System at RHIC.

    Feature selection (FS) is a process to select features which are more informative.It is one of the important steps in knowledge discovery.The problem is that not all features are important.Some of the features may be redundant,and others may be irrelevant and noisy.The conventional supervised FS methods evaluate various feature subsets using an evaluation function or metric to select only those features which are related to the decision classes of the data under consideration.However,for many data mining applications,decision class labels are often unknown or incomplete,thus indicating the significance of unsupervised feature selection.However,in unsupervised learning,decision class labels are not provided.In this paper,we propose a new unsupervised quick reduct (QR) algorithm using rough set theory.The quality of the reduced data is measured by the classification performance and it is evaluated using WEKA classifier tool.The method is compared with existing supervised methods and the result demonstrates the efficiency of the proposed algorithm.

    Full Text Available We describe a novel approach to precise searching in the full content of digital libraries. The Searchbench (for search workbench is based on sentence-wise syntactic and semantic natural language processing (NLP of both born-digital and scanned publications in PDF format. The term born-digital means natively digital, i.e. prepared electronically using typesetting systems such as LaTeX, OpenOffice, and the like. In the Searchbench, queries can be formulated as (possibly underspecified statements, consisting of simple subject-predicate-object constructs such as ‘algorithm improves word alignment’. This reduces the number of false hits in large document collections when the search words happen to appear close to each other, but are not semantically related. The method also abstracts from passive voice and predicate synonyms. Moreover, negated statements can be excluded from the search results, and negated antonym predicates again count as synonyms (e.g. not include = exclude.In the Searchbench, a sentence-semantic search can be combined with search filters for classical full-text, bibliographic metadata and automatically computed domain terms. Auto-suggest fields facilitate text input. Queries can be bookmarked or emailed. Furthermore, a novel citation browser in the Searchbench allows graphical navigation in citation networks. These have been extracted automatically from metadata and paper texts. The citation browser displays short phrases from citation sentences at the edges in the citation graph and thus allows students and researchers to quickly browse publications and immerse into a new research field. By clicking on a citation edge, the original citation sentence is shown in context, and optionally also in the original PDF layout.To showcase the usefulness of our research, we have a applied it to a collection of currently approx. 25,000 open access research papers in the field of computational linguistics and language technology, the ACL

    We live in an information age that requires us, more than ever, to represent, access, and use information. Over the last several decades, we have developed a modern science and technology for information retrieval, relentlessly pursuing the vision of a "memex" that Vannevar Bush proposed in his seminal article, "As We May Think." Faceted search plays a key role in this program. Faceted search addresses weaknesses of conventional search approaches and has emerged as a foundation for interactive information retrieval. User studies demonstrate that faceted search provides more

  2. Are search committees really searching?

    Academic chair searches are admittedly a labor-intensive process, but they are made more difficult and often lead to less-than-optimal outcomes because search committees spend their time "advertising," "looking," but not truly searching for academic chairs. At the onset, certain "realities" must be acknowledged, including (1) understanding that unless your organization is renowned in the specialty for which you are conducting the search, candidates won't be pounding at your door for a job, (2) searches that fail to include an overall assessment of the department in question are likely to miss the mark, (3) chairs must have demonstrated not only clinical expertise but also business savvy, (4) the best candidate is not necessarily someone who is already a department chair, (5) when it comes to chair searches, it's a buyer's market, and (6) the search process is inextricably linked to the success of the search. Key to the process of conducting an academic chair search are the judicious formation of the search committee; committee members' willingness to do their homework, attend all committee meeting, and keep the committee's activities confidential; crafting, not revising, the current job description for the open chair position; interviewing viable candidates rather than all candidates and adhering to a coordinated interviewing process; and evaluating internal and external candidates according to the same parameters.

  4. JISCARD GUI, a graphical interface application for simple and quick calculation of aviation route doses

    International Nuclear Information System (INIS)

    Pilots, flight attendants, and passengers aboard jet aircrafts are subjected to higher cosmic radiation levels at high altitude than on the ground. Additional dose, received during flight is called 'aviation route dose'. Addressing the needs for precise and easy determination of aviation route doses (Sv), the authors have developed a new application 'JISCARD GUI' with a graphical user interface which provides dose rate (Sv/h) distribution along a flight route and aviation route dose. The graphical interface made with Adobe Flash provide functions to select airports on dynamic map or to search by airport/city names, and to report resulting aviation route doses and graphs of dose rate change through a flight. Dose rate data at several cut off rigidity, Rc and force field potential, FFP were calculated in advance using a PHITS-based analytical model and stored in the server as matrix data. Upon user's request of departure/arrival airports and flight date, interpolation using matrix data substantiates derivation of dose rate distribution in a simple and quick manner with sufficient accuracy. Precision of the dose calculation was verified by comparison with JISCARD EX (MS-Excel version) released in September 2008. This advanced application will be open to public through the website of the National Institute of Radiological Sciences in the near future. (author)

    Full Text Available Abstract Background Patients with acute chest pain are often referred to the emergency ward and extensively investigated. Investigations are costly and could induce unnecessary complications, especially with invasive diagnostics. Nevertheless, chest pain patients have high mortalities. Fast identification of high-risk patients is crucial. Therefore several strategies have been developed including specific symptoms, signs, laboratory measurements, and imaging. Methods/Design The Quick Identification of acute Chest pain Study (QICS will investigate whether a combined use of specific symptoms and signs, electrocardiography, routine and new laboratory measures, adjunctive imaging including electron beam (EBT computed tomography (CT and contrast multislice CT (MSCT will have a high diagnostic yield for patients with acute chest pain. All patients will be investigated according a standardized protocol in the Emergency Department. Serum and plasma will be frozen for future analysis for a wide range of biomarkers at a later time point. The primary endpoint is the safe recognition of low-risk chest pain patients directly at presentation. Secondary endpoint is the identification of a wide range of sensitive predictive clinical markers, chemical biomarkers and radiological markers in acute chest pain patients. Chemical biomarkers will be compared to quantitative CT measurements of coronary atherosclerosis as a surrogate endpoint. Chemical biomarkers will also be compared in head to head comparison and for their additional value. Discussion This will be a very extensive investigation of a wide range of risk predictors in acute chest pain patients. New reliable fast and cheap diagnostic algorithm resulting from the test results might improve chest pain patients' prognosis, and reduce unnecessary costs and diagnostic complications.

    "Scientific community" refers to a group of people collaborating together on scientific-research-related activities who also share common goals, interests, and values. Such communities play a key role in many bioinformatics activities. Communities may be linked to a specific location or institute, or involve people working at many different institutions and locations. Education and training is typically an important component of these communities, providing a valuable context in which to develop skills and expertise, while also strengthening links and relationships within the community. Scientific communities facilitate: (i) the exchange and development of ideas and expertise; (ii) career development; (iii) coordinated funding activities; (iv) interactions and engagement with professionals from other fields; and (v) other activities beneficial to individual participants, communities, and the scientific field as a whole. It is thus beneficial at many different levels to understand the general features of successful, high-impact bioinformatics communities; how individual participants can contribute to the success of these communities; and the role of education and training within these communities. We present here a quick guide to building and maintaining a successful, high-impact bioinformatics community, along with an overview of the general benefits of participating in such communities. This article grew out of contributions made by organizers, presenters, panelists, and other participants of the ISMB/ECCB 2013 workshop "The 'How To Guide' for Establishing a Successful Bioinformatics Network" at the 21st Annual International Conference on Intelligent Systems for Molecular Biology (ISMB) and the 12th European Conference on Computational Biology (ECCB).

    The effect of browse plants (Piliostigma thonningii, Daniellia oliveri, Afzelia africana, Pterocarpus erinaceus and Annona senegalensis) supplementation on nutrient intake, digestibility, nutritive value and N utilization and growth performance of buckling goats fed threshed sorghum top (TST) was investigated using 24 Red Sokoto goats (9.0 ± 0.25 kg) body weight (BW) which were randomly assigned to one of the six diets in a completely random design. Intakes of dry matter (DM) and nutrients, feed conversion ratio, digestibility of nutrients except for neutral detergent fibre (NDF) and acid detergent fibre (ADF), digestible organic matter (DOM), digestible crude protein (DCP), energy concentration, N utilization and average daily gain were superior (P < 0.05) in TST-supplemented diets compared to sole TST diet. Among the supplemental fodders, intakes of forage, DM, condensed tannins and most of the nutrients; digestibility of DM, crude protein (CP) and non-fibre carbohydrate, DOM and DCP; and N absorbed, balance and retention were greater (P < 0.05) in A. africana relative to the other fodders. Results indicate that the entire browse fodders are good supplements to low quality TST, though A. africana appears to have a better nutritive value. PMID:25863959

Therefore, the objective of this study was to investigate comprehension of discharge ­instructions among older patients admitted to a Quick Diagnostic Unit (QDU.Methods: One hundred and two patients discharged from the QDU answered a questionnaire covering understanding of their hospitalization and discharge plan. Patients’ ability to recall discharge instructions and awareness of comprehension deficits, ie, ability to identify the misconceived information, were evaluated by comparing the questionnaires with the discharge letters. The population was divided into an older group (age ≥65 years and a younger group.Results: The older group (n=40 was less able to recall correct medication instructions when compared to the younger group (54% versus 78%, respectively; P=0.02. In multiple logistic regression analysis, correct recall of medication instructions was 4.2 times higher for the younger group compared to the older group (odds ratio 4.2, 95% confidence interval 1.5–11.9, P=0.007 when adjusted for sex and education. The older patients were less aware of their own comprehension deficits, and in respect to medication instructions awareness decreased 6.1% for each additional year of age (odds ratio 0.939, 95% confidence interval 0.904–0.98, P=0.001 when adjusted for sex and education.Conclusion: Older patients were less able to recall correct medication instructions and less aware of their comprehension deficits after discharge from a QDU

    The perplexing nature of dynamic glycosylation modification plays imperative role in determining the regulatory role of key glycoconjugates involved in immune system. Systematic analysis of change in expression pattern of glycogenes and lectins can bring in a comprehensive understanding of genetic basis of the glycobiological changes occurring in pathological condition. Advancement in the field of glycobiology has capacitated the process of linking gene expression changes of glycogenes with its biological function. This instigated us to systematically analyze changes in expression patterns focusing on glycome genomics under diverse gastrointestinal immune dysfunction background. To necessitate this, as a pilot project, we carefully integrated several publically available databases to construct a glycosylation process associated gene set as well as public expression microarray data associated with gastrointestinal infections into an online database called Glycosylation and Gut Associated Immune Tolerance (GlycoGAIT). Currently the database comprises of 548 well characterized genes belonging to glycogenes and lectins along with gene expression data obtained from human biopsy samples under both H. pylori infection and inflammatory bowel disease (IBD) condition. The user-friendly interface enables the users to quickly compare and interpret changes in expression patterns of glycome genomics under different gut associated inflammatory conditions.

    Full Text Available With the amount of available text data on the web growing rapidly, the need for users to search such information is dramatically increasing. Full text search engines and relational databases each have unique strengths as development tools but also have overlapping capabilities. Both can provide for storage and update of data and both support search of the data. Full text systems are better for quickly searching high volumes of unstructured text for the presence of any word or combination of words. They provide rich text search capabilities and sophisticated relevancy ranking tools for ordering results based on how well they match a potentially fuzzy search request. Relational databases, on the other hand, excel at storing and manipulating structured data -- records of fields of specific types (text, integer, currency, etc.. They can do so with little or no redundancy. They support flexible search of multiple record types for specific values of fields, as well strong tools for quickly and securely updating individual records. The web being a collection of largely unstructured document which is ever growing in size, the appeal of using RDBMS for searching this collection of documents has become very costly.This paper describes the architecture, design and implementation of a prototype website search engine powered by Lucene to search through any website. This approach involves the development of a small scale web crawler to gather information from the desired website. The gathered information are then converted to a Lucene document and stored in the index. The time taken to search the index is very short when compared with how long it takes for a relational database to process a query.

Food Chem. 44, 3230-3234] for tannin analysis, using 27 tropical browse plants. In this method, the amount of PEG bound to a plant sample is assumed to be a reflection of its tannin content. The method was modified to exclude the use of non-tanniniferous substrate for estimating non-specific binding (NSB) in tannin-containing substrates. Non-specific binding values varied widely (0.4-2.8 mg PEG/100 mg DM tannin-free substrate) when the tannin-free substrate was changed from wheat straw to either rye grass or maize shoots. We therefore propose a modified radiolabelled PEG-binding method to estimate the level of PEG-binding (PEGb) to tannin-containing foliage without using tannin-free substrate to correct for non-specific binding. In this approach, incremental levels of each tanniniferous substrate were used to generate PEGb values. The resultant linear response was analysed and tannin activity was expressed as the slope of the response curve (PEGbSlope) observed for each substrate. The slope takes into account the non-specific binding in each substrate, thus PEGbSlope does not require correction for NSB using tannin-free samples. This approach improved the correlation between PEGb and the {sup 125}I-labelled bovine serum albumin precipitation assay. Relationships between the modified PEG-binding assay and radiolabelled bovine serum albumin assay, in vitro tannin bioassay and colorimetric assays are presented. (author)

    The collection of electronic books held by the Library is steadily expanding, but there are still many titles not available online. However, to some extent Google is bridging the gap.   Google Books is an initiative launched by Google in 2004, in collaboration with a range of publishers and large libraries, which provides the books online and enables searches of the text from cover to cover. For titles that are out of copyright, or in cases where Google has struck an agreement with the publisher, the entire books can be read online. For other books, users can still search in the entire text but, depending on the agreement reached with the publisher, they may only be able to read a limited amount of pages (limited preview) or a few lines of text (known as snippets). Google Books also provides additional information such as reviews and links to related titles. Today, there are more than 15 million scanned books in Google Books.

  9. Quantum Database Search can do without Sorting

    CERN Document Server

    Patel, A

    2001-01-01

    Sorting is a fundamental computational process, which facilitates subsequent searching of a database. It can be thought of as factorisation of the search process. The location of a desired item in a sorted database can be found by classical queries that inspect one letter of the label at a time. For an unsorted database, no such classical quick search algorithm is available. If the database permits quantum queries, however, then mere digitisation is sufficient for efficient search. Sorting becomes redundant with the quantum superposition of states. A quantum algorithm is written down which locates the desired item in an unsorted database a factor of two faster than the best classical algorithm can in a sorted database. This algorithm has close resemblance to the assembly process in DNA replication.

In the present work, the Gallagher model has been used in connection with NeQuick to provide a more realistic representation of the electron concentration distribution in the plasmasphere. An analysis of the impact of the proposed modification in low geomagnetic latitudes (±40°) on modeled vertical total electron content has been performed for different levels of solar activity, season, and universal time. In addition, GPS vertical total electron content values obtained from seven IGS (International GPS Service) station data have been compared with the NeQuick and NeQuick+Gallagher vertical total electron content values, confirming the importance of including a plasmaspheric formulation in the NeQuick model.

    We seek to improve information retrieval in a domain-specific col-lection by clustering user sessions as recorded in a click log and then classifying later user sessions in real-time. As a preliminary step, we explore, the main as-sumption of this approach: whether user sessions in such a site...... relate to the question that they are answering. The contribution of this paper is the evalua-tion of the suitability of common machine learning metrics (measuring the dis-tance between two sessions) to distinguish sessions of users searching for the answer to same or different questions. We found that...... sessions for people an-swering the same question are significantly different that those answering dif-ferent questions, but results are dependent on the distance metric used. We ex-plain why some distance metrics performed better than others....

    Distant homology search tools are of great help to predict viral protein functions. However, due to the lack of profile databases dedicated to viruses, they can lack sensitivity. We constructed HMM profiles for more than 80,000 proteins from both phages and archaeal viruses, and performed all pairwise comparisons with HHsearch program. The whole resulting database can be explored through a user-friendly "Phagonaute" interface to help predict functions. Results are displayed together with their genetic context, to strengthen inferences based on remote homology. Beyond function prediction, this tool permits detections of co-occurrences, often indicative of proteins completing a task together, and observation of conserved patterns across large evolutionary distances. As a test, Herpes simplex virus I was added to Phagonaute, and 25% of its proteome matched to bacterial or archaeal viral protein counterparts. Phagonaute should therefore help virologists in their quest for protein functions and evolutionary relationships. PMID:27254594

    A useful measure of quality of life should be easy and quick to complete. Recently, we reported the development and validation of a shortened Chinese version of the Functional Living Index – Cancer (FLIC), which we called the Quick-FLIC. In the present study of 327 English-speaking and 221 Chinese-speaking cancer patients, we validated the English version of the Quick-FLIC and further assessed the Chinese version. The 11 Quick-FLIC items were administered alongside the 11 remaining items of the full FLIC, but there appeared to be little context effect. Validity of the English version of the Quick-FLIC was attested by its strong correlation with two other measures of quality of life, and its ability to detect differences between patients with different performance status and treatment status (each P<0.001). Its internal consistency (alpha=0.86) and test–retest reliability (intraclass correlation=0.76) were also satisfactory. The measure was responsive to changes in performance status (P<0.001). The Chinese version showed similar characteristics. The Quick-FLIC behaved in ways that are highly comparable with the FLIC, even though the Quick-FLIC comprised only 11 items whereas the FLIC comprised 22. Further research is required to see whether the use of shorter instruments can improve data quality and response rates, but the fact that shorter instruments place less burden on the patients is itself inherently important.

    Full Text Available Liquid nitrogen spraying fluidized bed was used for Individual Quick Freezing (IQF of blue berries; processing technology and quality change of frozen samples during storage stage were analyzed in this study. Regular and mixed experimental design were used to confirm the quick freeze process of blueberries by means of setting different freezing temperature, wind velocity and the height of bed-layer. Multiple linear regression analysis indicates that the suitable process conditions for quick-freezing blueberries in LN2-spraying fluidized bed were -40°C freezing temperature, 4.5 m/sec wind speed and 3.6 cm bed height. Environmental Scanning Electron Microscopy (ESEM results show that the inner microstructure of the fluidized quick-frozen blueberries has better compactness, uniformity and destructiveness than that of the slow-frozen blueberries in -18°C refrigerator. Texture Analysis (TPA and the technology of image processing were used to analyze the different of blueberries in firmness and internal color between the fluidized quick-frozen and slow-frozen in -18°C refrigerator. The results show that the quality of the fluidized quick-frozen blueberries has better than that of the slow-frozen blueberries in -18°C refrigerator. The storage life of blueberry by LN2 spraying fluidized quick-frozen was confirmed that is around 150 days which in much better than that of the slow-frozen sample with the storage life of 100 days.

    Full Text Available In the current scenario, web page result personalization is playing a vital role. Nearly 80 % of the users expect the best results in the first page itself without having any persistence to browse longer in URL mode. This research work focuses on two main themes: Semantic web search through online and Domain based search through offline. The first part is to find an effective method which allows grouping similar results together using BookShelf Data Structure and organizing the various clusters. The second one is focused on the academic domain based search through offline. This paper focuses on finding documents which are similar and how Vector space can be used to solve it. So more weightage is given for the principles and working methodology of similarity propagation. Cosine similarity measure is used for finding the relevancy among the documents.

    2014-04-01

    Full Text Available Along with the widespread application of the electronic commerce in the modern business, the logistic distribution has become increasingly important. More and more enterprises recognize that the logistic distribution plays an important role in the process of production and sales. A good routing for logistic distribution can cut down transport cost and improve efficiency. In order to cut down transport cost and improve efficiency, a routing optimization based on taboo search for logistic distribution is proposed in this paper. Taboo search is a metaheuristic search method to perform local search used for logistic optimization. The taboo search is employed to accelerate convergence and the aspiration criterion is combined with the heuristics algorithm to solve routing optimization. Simulation experimental results demonstrate that the optimal routing in the logistic distribution can be quickly obtained by the taboo search algorithm

We propose an information-processing model based on TAM in which perceived risk online is an antecedent and consumer loyalty towards the service is the ultimate outcome In order to achieve this objective and test the proposed hypotheses, a between-subjects experimental design was chosen, using one independent variable namely with two level: processing language (Spanish vs. English. The final sample comprised 264 Spanish users. Half the sample browsed in Spanish, and the other half in English. The results demonstrated that the cultural dimension ‘uncertainty avoidance’ moderates the effect of perceived risk on perceived ease of use and usefulness. Perceived ease of use or perceived usefulness influenced to attitude towards the website, depending on whether the language used to process the information on the site conveys cultural values with a shorter or longer-term orientation. Languages, as a cultural framework, didn´t moderate the relationship between attitude towards the website and loyalty towards the tourist destination.

    Overabundance of deer can assist the intrusion of invasive plants through browse, leading to homogenization of plant communities. Public attitudes towards native and invasive plant species and white-tailed deer browse related to personal experiences, can be changed through education focusing public awareness of ramifications of deer browse on native and invasive plants. I developed an interactive, interpretive Self-Guided Walking Tour brochure of the "You Can Trail" to provide an educational outreach program for visitors of Crooked Creek Environmental Learning Center that includes ecologically important native and invasive plants species from my investigation. This research study focuses on the overall abundance of native and invasive plant species once Odocoileus virginianus have been removed from the landscape during collection periods in June and September 2013 from exclosure and access plots that were maintained for seven years. Similarity of abundance were found in native and invasive abundance of forbs, bushes and percentage of ground cover. Differences included native bush volume being greater than invasive bush volume in the access plot in June with opposing results in the exclosure plot, being greater in invasive bush volume. However, in September, native and invasive bush volume was similar within the exclosure plot, while invasive bush volume decreased in the access plot. Invasive vines recorded in the June access plot were absent in the September collection period.

    Fibre, crude protein and tannin concentrations were measured in browse species from the semi-arid region of Northeast Brazil during the dry and wet seasons. The effects of oven-, sun- and shade-drying and of urea treatment were also determined. Crude protein (CP) content varied from 103 to 161 g/kg dry matter (DM) and the browses had similar CP content in the two seasons (during 2002) (102-161 and 107-153 g/kg DM in the wet and dry seasons, respectively). Total tannin concentrations ranged from 13 to 201 g/kg DM amongst the browses and were higher in the dry season. A 30-d treatment with urea reduced extractable tannins significantly (P < 0.05). The urea treatment was also most effective at reducing the in vitro effects of tannins compared to the other drying treatments. This was demonstrated by measuring the effect of polyethylene glycol (PEG) on gas production. Addition of PEG increased gas production of oven- (81.4%), sun- (78.5%) and shade-dried (76.7%) samples much more compared to urea treated samples (10.9%). (author)

    BACKGROUND Health care queries rank among the most frequent topics of information-seeking activity initiated by users of commercial search engines. The quality of information located through existing search engine technology has received little attention, especially when considering the widely varied knowledge levels of internet users. OBJECTIVE This study sought to create a benchmark technology assessment of online health search trends and practices, with corresponding evaluation of its applicability within the Federal Health Architecture (FHA) plan for a nationwide, interoperable health information infrastructure. DESIGN Exploratory technology assessment, analyzing focus group participants' views on barriers to effective health information searching, using existing commercial search engine technologies and methods. SETTING AND PARTICIPANTS Focus group, national leaders in electronic health care (e-health). RESULTS A variety of web-based assessment tools are available for consumers to be able to identify reliable health websites; however, many may be too difficult for the layperson to use or understand. Existing search technologies are increasingly powerful, although the expanding volume of information on the internet suggests the need for better mediated searching. Search engines provide consumers a means for quickly bypassing information that appears too technical for their individual knowledge level, and at times, searchers often overlook critical information most relevant to their needs. Overall, existing search technologies need to be more interactive, visible, and context-driven, and supported by better technology assessment methodologies, scalability of information, and enhanced access by underserved subgroups. CONCLUSION Future technology assessments are needed to provide structure for interoperability of health information systems, especially where consumers, providers, and payer systems intersect. State-of-the-art search engine technologies are still not

    Decades of innovations in combinatorial problem solving have produced better and more complex algorithms. These new methods are better since they can solve larger problems and address new application domains. They are also more complex which means that they are hard to reproduce and often harder to fine-tune to the peculiarities of a given problem. This last point has created a paradox where efficient tools are out of reach of practitioners. Autonomous search (AS) represents a new research field defined to precisely address the above challenge.

  20. Using Google Search Appliance (GSA) to search digital library collections: A Case Study of the INIS Collection Search

    International Nuclear Information System (INIS)

    Google Search has established a new standard for information retrieval which did not exist with previous generations of library search facilities. The INIS hosts one of the world’s largest collections of published information on the peaceful uses of nuclear science and technology. It offers on-line access to a unique collection of 3.6 million bibliographic records and 483,000 full texts of non-conventional (grey) literature. This large digital library collection suffered from most of the well-known shortcomings of the classic library catalogue. Searching was complex and complicated, it required training in Boolean logic, full-text searching was not an option, and response time was slow. An opportune moment to improve the system came with the retirement of the previous catalogue software and the adoption of GSA as an organization-wide search engine standard. INIS was quick to realize the potential of using such a well-known application to replace its on-line catalogue. This paper presents the advantages and disadvantages encountered during three years of GSA use. Based on specific INIS-based practice and experience, this paper also offers some guidelines on ways to improve classic collections of millions of bibliographic and full-text documents, while reaping multiple benefits, such as increased use, accessibility, usability, expandability and improving user search and retrieval experiences.

    Performances of Galileo NeQuick model are analyzed over the continental and oceanic regions for the whole year of 2013. The three broadcast coefficients of NeQuick are computed from 23 globally distributed tracking stations of the International GNSS Services (IGS), by ingesting the Global Positioning System (GPS) derived ionospheric total electron content (TEC) into the original NeQuick 2 model. In continental regions, the ionospheric TEC derived from 34 IGS stations are used as references for the comparison. In oceanic regions, where the IGS stations are sparse,high-quality vertical TEC sources provided by JASON 1 and 2 altimeters are used as references. GPS broadcast Klobuchar, the original and broadcast NeQuick can mitigate the ionospheric delay by 56.8%, 63.3% and 72.4%, respectively, when compared to GPS TEC. The three models can correct 51.1%, 61.2 % and 68.6% of the ionospheric delay when compared to JASON TEC. Galileo NeQuick model outperforms Klobuchar by 15.6% and 17.5% over the continental and oceanic regions, respectively, for the test period.

    The global ionospheric maps (GIMs), generated by Jet Propulsion Laboratory (JPL) and Center for Orbit Determination in Europe (CODE) during a period over 13 years, have been adopted as the primary source of data to provide global ionospheric correction for possible single frequency positioning applications. The investigation aims to assess the performance of new NeQuick model, NeQuick 2, in predicting global total electron content (TEC) through ingesting the GIMs data from the previous day(s). The results show good performance of the GIMs-driven-NeQuick model with average 86% of vertical TEC error less than 10 TECU, when the global daily effective ionization indices (Az) versus modified dip latitude (MODIP) are constructed as a second order polynomial. The performance of GIMs-driven-NeQuick model presents variability with solar activity and behaves better during low solar activity years. The accuracy of TEC prediction can be improved further through performing a four-coefficient function expression of Az versus MODIP. As more measurements from earlier days are involved in the Az optimization procedure, the accuracy may decrease. The results also reveal that more efforts are needed to improve the NeQuick 2 model capabilities to represent the ionosphere in the equatorial and high-latitude regions. PMID:25815369

  5. Quick radioimmunoassay for plasma immunoreactive gastrin. Application for localizing occult gastrinoma(s) during operation

    International Nuclear Information System (INIS)

    A rapid method for determining gastrin, quick gastrin, has been developed. Separation/washing procedure has been improved and can be completed within three minutes. It required only 48 minutes for the assay of 22 blood samples. Quick gastrin is a RIA that uses magnetic particles. On magnetic particles, a goat anti-rabbit IgG antibody is bound covalently. An anti-human gastrin rabbit antibody is bound to an anti-rabbit IgG antibody. Assay is started by adding the magnetic particles to a mixture of sample and 125I-gastrin. Following 30 minute incubation at 37degC, the particles are sedimented in a magnetic field and washed. The gastrin content of the sample is then quantitated by counting radioactivity of the particles. Incomplete equilibration of antigen-antibody reaction is corrected using standard solution prepared from charcoal treated plasma. The immunoreactive gastrin values by quick gastrin correlated well with those by a commercial assay kit (Gammadab RIA kit; y=1.01x+4.3, r=0.99). When compared to a reported conventional rapid assay, quick gastrin is easier and more accurate. Quick gastrin is sensitive enough to use for intra-operative determination of gastrin. We applied quick gastrin to the samples obtained from intra-operative secretin test in a gastrinoma patient. Twofold increase in gastrin after injection of secretin clearly indicated the existence of occult gastrinomas in her pancreas. When gastrin was assayed with the conventional rapid method, the increase in gastrin was less and did not reach the criteria for existence of gastrinoma. (author)

    When an earthquake occurs, seismologists want to use recorded seismograms to infer its location, magnitude and source-focal mechanism as quickly as possible. If such information could be determined immediately, timely evacuations and emergency actions could be undertaken to mitigate earthquake damage. Current advanced methods can report the initial location and magnitude of an earthquake within a few seconds, but estimating the source-focal mechanism may require minutes to hours. Here we present an earthquake search engine, similar to a web search engine, that we developed by applying a computer fast search method to a large seismogram database to find waveforms that best fit the input data. Our method is several thousand times faster than an exact search. For an Mw 5.9 earthquake on 8 March 2012 in Xinjiang, China, the search engine can infer the earthquake’s parameters in <1 s after receiving the long-period surface wave data.

    TANG Hua-ping; TANG Yun-jun; TAO Gong-an

    2006-01-01

    A kind of active vibration control method was presented based on active damping and optimization design for driving load of multibody system with quick startup and brake. Dynamical equation of multibody system with quick startup and brake and piezoelectric actuators intelligent structure was built. The optimum driving load was calculated by applying the presented method. The self-sensing and self-tuning closed-loop active vibration control in quick startup and brake process was realized. The control algorithm, using local velocity negative feedback, i.e. the output of a sensor only affects the output of the actuator collocated, can induce damping effectively to actively suppress the system vibration. Based on the optimization design for driving load of multibody system with quick startup and bake, the active damping of piezoelectric actuators intelligent structure was used to farther suppress the vibration of system. Theoretical analysis and calculation of numerical show that the proposed method makes the vibration of system decrease more than the optimal design method for driving load of multibody system.

  2. EXPERIMENTAL RESEARCH AND DESIGN ON HEAT TRANSFER OF EVAPORATOR USED IN THE LARGE QUICK FREEZE PLANT

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    The evaporator is the main part of a quick-freeze equipment. There are many factors influencing the heat transfer coefficient of an evaporator. The most important factors among them are the fin shape, tube diameter, distance of fin space, frost, and velocity of air flow etc. They mainly influence the thermal efficiency of an evaporator, and therefore its thermal efficiency has direct relationship with the whole efficiency of the quick freeze plant. Evaporators with different structural types have different heat transfer efficiency. In order to obtain high efficiency structure of evaporator, 8 evaporator models with different fin shape, tube diameter and tube arrangement are analyzed and compared. The calculation results show that the integral waved fins, equilateral-triangle arranged small diameter tubes and varying fin-spacing has the highest heat transfer coefficient. The experimental result also shows that the evaporator with this type of structure has better thermal efficiency. The experimental result is in good agreement with the calculation result. It can instruct engineering design for usual designer. A real quick-freeze equipment is designed and put into production. The result shows that, compared with traditional domestic quick-freeze equipments, this equipment decreases by 40% in size and by 20% in energy consumption.

  10. A multidisciplinary geophysical, geotechnical and hydrogeological investigation of quick-clay landslides in Sweden

    2012-04-01

    In Spring 2011, the Society of Exploration Geophysicists (SEG) through its Geoscientists Without Borders (GWB) program sponsored our project to study clay-related landslides in the Nordic countries. This project will study quick clay or rapid earth flow landslides in Sweden. Undisturbed quick clay resembles a water-saturated gel. When a mass of quick clay undergoes sufficient stress, it instantly turns into a flowing ooze, a process known as liquefaction. A small block of quick clay can liquefy from a stress change due to as little as a modest blow from a human hand, while a larger deposit is mainly vulnerable to greater stress changes, such as increased saturation by excess rainwater. Despite their abundance, our geophysical understanding of clay behavior in terms of both changes in the geometrical shape (clay formations) and changes in the physical properties are limited and require a better understanding. Quick clay landslides are not particularly constrained to steep slopes and have been known to slide even in low-to-moderate angle slopes. Geophysical investigations began in September 2011 over a known landslide scar near the Göta river in southwest Sweden, an area known to contain quick clays in parts of it. The investigations involved 2D and 3D P- and S-wave source and receiver surveys, geoelectrics, controlled-source and radio-magnetotellurics, ground gravity and magnetic surveys. These data in combination with existing geotechnical information and hydrogeological investigations should allow better insight into the mechanism(s) governing clay-related landslides in the Nordic countries and to provide high-resolution images of subsurface structures down to the bedrock. We will present preliminary results from the seismic investigations, including the 2D and 3D reflection and refraction surveys. The reflection seismic data show excellent quality and image the bedrock topography and internal layering above it down to about 100 m. Tomography results suggest the

    When earthquake or torrential rainfall cause deep catastrophic landslides, landslide dams can be formed in mountainous region. If water overflows from the landslide dams, large scale debris flow can occurs and possibly causes serious disasters in the downward region. Debris flow caused by the overflow from landslide dam is possible to affect the larger area than normal debris flow and flash flood. It is important for both a decision maker and resident in the area to recognize the disaster prone area as early as possible. For that reason, it is important to establish a quick analysis method for estimating debris flow prone area caused by overflow from landslide dams under the emergency situation. This situation requires the method to have both accuracy and speed for release. Nonetheless these two factors have trade-off relationship. We recently developed the quick analysis method to estimate debris flow disaster prone area caused by overflow from landslide dams. The method including the ways of efficient survey and numerical simulation programs called QUAD-L (QUick Analysis system for Debris flow caused by Landslide dam overflow). Our quick analysis system was actually applied to show the area for evacuation against debris flow caused by overflow from landslide dam formed by the 2011 Typhoon Talas which hit mainly the central region of Japan on September 2-4th, 2011. In addition to background of this application, since May 1st, 2011, Erosion and Sediment Control (SABO) Department of the Ministry of Land, Infrastructure, Transport and Tourism, Japan (MLIT) launched a new scheme using above-mentioned quick analysis method.

    2014-07-01

    Full Text Available Libraries are facing many challenges today. In addition to diminishing funding and increased user expectations, the use of classic library catalogues is becoming an additional challenge. Library users require fast and easy access to information resources regardless whether the format used is paper or electronic. Google search, with its speed and simplicity, set up a new standard for information retrieval which is hard to achieve with the previous generation of library search facilities. Put in a position of David versus Goliath, many small, and even larger libraries, are losing the battle with Google and letting many of its users use Google rather than library catalogues.The International Nuclear Information System (INIS hosts one of the world’s largest collections of published information on the peaceful uses of nuclear science and technology. It offers online access to a unique collection of 3.6 million bibliographic records and 320,000 full-texts of non-conventional (grey literature. This large digital library collection suffered from most of the well-known shortcomings of the classic library catalogue. Searching was complex and complicated, required some training in using Boolean logic, full-text searching was not an option, and the response time was slow. An opportune moment came with the retirement of the previous catalogue software and with the adoption of Google Search Appliance (GSA as an organization-wide search engine standard. INIS was quick to realize a great potential in using such a well-known application as a replacement for its online catalogue and this paper presents the advantages and disadvantages encountered during three years of GSA use. Based on specific INIS-based practice and experience, this paper also offers some guidelines on ways to improve classic collections of millions of bibliographic and full-text documents, while achieving multiple benefits such as increased use, accessibility, usability, expandability and

    In the future, we hope to see an open and thriving data market in which users can find and select data from a wide range of data providers. In such an open access market, data are products that must be packaged accordingly. Increasingly, eCommerce sellers present heterogeneous product lines to buyers using faceted browsing. Using this approach we have developed the Ontogrator platform, which allows for rapid retrieval of data in a way that would be familiar to any online shopper. Using Knowledge Organization Systems (KOS), especially ontologies, Ontogrator uses text mining to mark up data and faceted browsing to help users navigate, query and retrieve data. Ontogrator offers the potential to impact scientific research in two major ways: 1) by significantly improving the retrieval of relevant information; and 2) by significantly reducing the time required to compose standard database queries and assemble information for further research. Here we present a pilot implementation developed in collaboration with the Genomic Standards Consortium (GSC) that includes content from the StrainInfo, GOLD, CAMERA, Silva and Pubmed databases. This implementation demonstrates the power of ontogration and highlights that the usefulness of this approach is fully dependent on both the quality of data and the KOS (ontologies) used. Ideally, the use and further expansion of this collaborative system will help to surface issues associated with the underlying quality of annotation and could lead to a systematic means for accessing integrated data resources.

    2004-01-01

    This paper examines piggybacking NASA, university, and industry payloads on commercial geosynchronous satellites. NASA's RSDO Office awarded Geo Quick Ride (GQR) study contracts in 1998 to spacecraft manufactures to examine the issues with flying secondary payloads. The study results were very promising. Commercial communication satellites have frequent flights and significant unused resources that could be used to fly secondary payloads. However, manifesting secondary payloads on a commercial revenue-generating satellite is a complex problem to solve. The solution requires multiple simultaneous approaches in order to be successful. There are business, economic, technical, schedule, and organizational issues to be resolved. This paper examines the Geo Quick Ride (GQR) concept, discusses the development issues, and describes how this concept solves many of these issues.

  4. Liquid Phase 3D Printing for Quickly Manufacturing Metal Objects with Low Melting Point Alloy Ink

    CERN Document Server

    Wang, Lei

    2014-01-01

    Conventional 3D printings are generally time-consuming and printable metal inks are rather limited. From an alternative way, we proposed a liquid phase 3D printing for quickly making metal objects. Through introducing metal alloys whose melting point is slightly above room temperature as printing inks, several representative structures spanning from one, two and three dimension to more complex patterns were demonstrated to be quickly fabricated. Compared with the air cooling in a conventional 3D printing, the liquid-phase-manufacturing offers a much higher cooling rate and thus significantly improves the speed in fabricating metal objects. This unique strategy also efficiently prevents the liquid metal inks from air oxidation which is hard to avoid otherwise in an ordinary 3D printing. Several key physical factors (like properties of the cooling fluid, injection speed and needle diameter, types and properties of the printing ink, etc.) were disclosed which would evidently affect the printing quality. In addit...

  5. Rapidly measuring the speed of unconscious learning: amnesics learn quickly and happy people slowly.

    Directory of Open Access Journals (Sweden)

    Zoltan Dienes

    Full Text Available BACKGROUND: We introduce a method for quickly determining the rate of implicit learning. METHODOLOGY/PRINCIPAL FINDINGS: The task involves making a binary prediction for a probabilistic sequence over 10 minutes; from this it is possible to determine the influence of events of a different number of trials in the past on the current decision. This profile directly reflects the learning rate parameter of a large class of learning algorithms including the delta and Rescorla-Wagner rules. To illustrate the use of the method, we compare a person with amnesia with normal controls and we compare people with induced happy and sad moods. CONCLUSIONS/SIGNIFICANCE: Learning on the task is likely both associative and implicit. We argue theoretically and demonstrate empirically that both amnesia and also transient negative moods can be associated with an especially large learning rate: People with amnesia can learn quickly and happy people slowly.

  7. QuickPol: Fast effective beam matrices calculation for CMB polarization

    Hivon, Eric; Ponthieu, Nicolas

    2016-01-01

    Current and planned observations of the Cosmic Microwave Background (CMB) polarization anisotropies, with their ever increasing number of detectors, have reached a potential accuracy that requires a very demanding control of systematic effects. While some of these systematics can be reduced in the design of the instruments, others will be have to be modeled and hopefully accounted for or corrected a posteriori. We propose QuickPol, a quick and accurate calculation of the full effective beam transfer function and of temperature to polarization leakage at the power spectra level, as induced by beam imperfections and mismatches between detector optical and electronic responses. All the observation details such as exact scanning strategy, imperfect polarization measurements and flagged samples are accounted for. Our results are validated on Planck-HFI simulations. We show how the pipeline can be used to propagate instrumental uncertainties up to the final science products, and could be applied to experiments with...

    International Nuclear Information System (INIS)

    This paper introduces the Quick-E-Scan methodology that has been developed to achieve the operational energy efficiency of small and medium enterprises (SMEs), characterized by being scarcely disposed to long energy audits and by a limited budget for energy management programs. On one side, through dividing the firm into functional units - either service (lighting, HVAC, etc.) or production units - the main consuming areas are identified and a criticality index is defined; conversely, an enhancement index highlights the gap of each unit towards the best available techniques (BATs) in energy management programs. Finally, a priority index, created with the junction of the two indexes, points out the most profitable areas in which energy saving measures should be implemented. The methodology, particularly quick and simple, has been successfully tested in 38 SMEs in Northern Italy.

  10. Quick evaluation of the neutron dose following a criticality accident by measurement of sodium 24 activity

    International Nuclear Information System (INIS)

    In order to quickly sort out the irradiated individuals following a criticality accident, the neutron dose can be evaluated quickly by measuring the sodium-24 activity induced in the human body. The report supplies the information necessary for this evaluation from the response of various detectors of current use in radiation protection. The first part describes the method of evaluation of sodium-24 activity (A) given by the reading (M) of each instrument. The second part describes the method of kerma evaluation from the measured sodium-24 activity. The third part is an experimental application of the method of kerma evaluation from the sodium-24 activity measured in a phantom irradiated in the SILENE reactor flux. The results given by radiation protection instruments are in good agreement with the calculated values for a front exposure and demonstrate the usefulness of measuring the induced sodium-24 activity by radiation protection instruments of current use

  11. Towards a numerical run-out model for quick-clay slides

    Highly sensitive glacio-marine clays occur in many relatively low-lying areas near the coasts of eastern Canada, Scandinavia and northern Russia. If the load exceeds the yield stress of these clays, they quickly liquefy, with a reduction of the yield strength and the viscosity by several orders of magnitude. Leaching, fluvial erosion, earthquakes and man-made overloads, by themselves or combined, are the most frequent triggers of quick-clay slides, which are hard to predict and can attain catastrophic dimensions. The present contribution reports on two preparatory studies that were conducted with a view to creating a run-out model tailored to the characteristics of quick-clay slides. One study analyzed the connections between the morphological and geotechnical properties of more than 30 well-documented Norwegian quick-clay slides and their run-out behavior. The laboratory experiments by Locat and Demers (1988) suggest that the behavior of quick clays can be reasonably described by universal relations involving the liquidity index, plastic index, remolding energy, salinity and sensitivity. However, these tests should be repeated with Norwegian clays and analyzed in terms of a (shear-thinning) Herschel-Bulkley fluid rather than a Bingham fluid because the shear stress appears to grow in a sub-linear fashion with the shear rate. Further study is required to understand the discrepancy between the material parameters obtained in laboratory tests of material from observed slides and in back-calculations of the same slides with the simple model by Edgers & Karlsrud (1982). The second study assessed the capability of existing numerical flow models to capture the most important aspects of quick-clay slides by back-calculating three different, well documented events in Norway: Rissa (1978), Finneidfjord (1996) and Byneset (2012). The numerical codes were (i) BING, a quasi-two-dimensional visco-plastic model, (ii) DAN3D (2009 version), and (iii) MassMov2D. The latter two are

    A web front-end has been recently developed and released to allow retrieving and plotting ionospheric parameters computed by the latest version of the model, NeQuick 2. NeQuick is a quick-run ionospheric electron density model particularly designed for trans-ionospheric propagation applications. It has been developed at the Aeronomy and Radiopropagation Laboratory (now T/ICT4D Laboratory) of the Abdus Salam International Centre for Theoretical Physics (ICTP) - Trieste, Italy with the collaboration of the Institute for Geophysics, Astrophysics and Meteorology (IGAM) of the University of Graz, Austria. To describe the electron density of the ionosphere up to the peak of the F2 layer, NeQuick uses a profile formulation which includes five semi-Epstein layers with modelled thickness parameters. Through a simple web interface users can exploit all the model features including the possibility of computing the electron density and visualizing the corresponding Total Electron Content (TEC) along any ground-to-satellite straight line ray-path. Indeed, the TEC is the ionospheric parameter retrieved from the GPS measurements. It complements the experimental data obtained with diverse kinds of sensors and can be considered a major source of ionospheric information. Since the TEC is not a direct measurement, a "de-biasing" procedure or calibration has to be applied to obtain the relevant values from the raw GPS observables. Using the observation and navigation RINEX files corresponding to a single receiver as input data, the web application allows the user to compute the slant and/or vertical TEC following the concept of the "arc-by-arc" offsets estimation. The combined use of both tools, freely available from the T/ICT4D Web site, will allow the comparison of experimentally derived slant and vertical TEC with modelled values. An online demonstration of the capabilities of the mentioned web services will be illustrated.

    2016-06-01

    Solder joint qualities of light-emitting diodes (LED) lamps have a significant effect on their lifetime. Due to variations in LEDs, the product lifetime is determined by the lowest performing component of the product when multi-LEDs are used. In this paper, we propose a quick electrical inspection method of solder joint quality for LED products, which is obtained by the heating curve measurement for a short time with the forward voltage as a temperature sensitive parameter. The utility of this quick inspection method is verified by the measurement of a solder voids ratio based on the most commonly used approaches in the industry—x-ray. The proposed method is cost effective and only needs around 1–5 s for each LED, which is about one third of the x-ray. Therefore, the quick electrical test method is both meaningful and promising especially when carrying out quality tests on large quantities of solder and can be a highly recommended method to be adopted by the LED lighting industry.

    2007-01-01

    There has been a great deal of interest in studying the crown of trees using remote sensing data. In this study, crown width was extracted from high-resolution QuickBird images for open Populus xiaohei plantations. Regression models for predicting the individual stem volumes of Populus xiaohei were established using extracted crown width, as well as estimated tree parameters (i.e. diameter at breast height [DBH] and tree height) as predictors. Our results indicated that crown width could be accurately extracted from QuickBird images using a multi-scale segmentation approach with a mean relative error of 5.74%, especially for wide-spacing stands. Using either extracted crown width alone or with estimated DBH and tree height can successfully estimate individual stem volume of Populus xiaohei with the R2 value ranging from 0.87 to 0.92 depending on different model forms. In particular, the two second-order polynomial models (model2 and model 6), based on QuickBird image-derived crown widths and estimated DBH and tree heights, respectively, were the best at describing the relationship between stem volume and tree characteristics.

It is because people today demand not only for qualityfood but also for speed. Quick service restaurant players explore on the approaches to optimize the efficiency of restaurant management. One important area that defines how well and efficient a fast food restaurant delivers its product and services to customers is its waiting line (queue management practices. The study was conducted at Lipa City, involving five popular quick service restaurants named by the researcher as QSR A, B, C, D, and E. It made used of 363customer respondents proportionally obtained from five restaurants.It intended to assess the extent of implementation of the queue management practices of the restaurants and the level of satisfaction of the customers in such practices in terms of customer arrival, waiting line and service facility. The findings revealed the queuing system used and the waiting line structured utilized by the restaurants. The extent of implementation of the queue management practices in the three areas mentioned of the five QSR’s was presented comparatively. Likewise, the level of customer’s satisfaction on the queue management practices was also determined. Significant difference in the extent of implementation and in the level of customer satisfaction were determined if the respondents were grouped according to restaurant’s profile. Recommendations in the improvement of queue were given based on the findings.

    2007-09-01

    PubMed and HighWire Press are both useful medical literature search engines available for free to anyone on the internet. We measured retrieval accuracy, number of results generated, retrieval speed, features and search tools on HighWire Press and PubMed using the quick search features of each. We found that using HighWire Press resulted in a higher likelihood of retrieving the desired article and higher number of search results than the same search on PubMed. PubMed was faster than HighWire Press in delivering search results regardless of search settings. There are considerable differences in search features between these two search engines.

    The traditional view of learning puts most of the emphasis on face-to-face teaching and curriculum. It is very slow and expensive. Many people try to find e-Learning systems and learning objects on the Web. But that can be very difficult to find what we need with the actual search engines. How can someone quickly find and with meaning the learning objects existing in the Web?

  14. A Graph Search Heuristic for Shortest Distance Paths

    Energy Technology Data Exchange (ETDEWEB)

    Chow, E

    2005-03-24

    This paper presents a heuristic for guiding A* search for finding the shortest distance path between two vertices in a connected, undirected, and explicitly stored graph. The heuristic requires a small amount of data to be stored at each vertex. The heuristic has application to quickly detecting relationships between two vertices in a large information or knowledge network. We compare the performance of this heuristic with breadth-first search on graphs with various topological properties. The results show that one or more orders of magnitude improvement in the number of vertices expanded is possible for large graphs, including Poisson random graphs.

  16. METADATA EXPANDED SEMANTICALLY BASED RESOURCE SEARCH IN EDUCATION GRID

    Institute of Scientific and Technical Information of China (English)

    2005-01-01

    With the rapid increase of educational resources, how to search for necessary educational resource quickly is one of most important issues. Educational resources have the characters of distribution and heterogeneity, which are the same as the characters of Grid resources. Therefore, the technology of Grid resources search was adopted to implement the educational resources search. Motivated by the insufficiency of currently resources search methods based on metadata, a method of extracting semantic relations between words constituting metadata is proposed. We mainly focus on acquiring synonymy, hyponymy, hypernymy and parataxis relations. In our schema, we extract texts related to metadata that will be expanded from text spatial through text extraction templates. Next, metadata will be obtained through metadata extraction templates. Finally, we compute semantic similarity to eliminate false relations and construct a semantic expansion knowledge base. The proposed method in this paper has been applied on the education grid.

  17. A Search Engine That's Aware of Your Needs

    2005-01-01

    Internet research can be compared to trying to drink from a firehose. Such a wealth of information is available that even the simplest inquiry can sometimes generate tens of thousands of leads, more information than most people can handle, and more burdensome than most can endure. Like everyone else, NASA scientists rely on the Internet as a primary search tool. Unlike the average user, though, NASA scientists perform some pretty sophisticated, involved research. To help manage the Internet and to allow researchers at NASA to gain better, more efficient access to the wealth of information, the Agency needed a search tool that was more refined and intelligent than the typical search engine. Partnership NASA funded Stottler Henke, Inc., of San Mateo, California, a cutting-edge software company, with a Small Business Innovation Research (SBIR) contract to develop the Aware software for searching through the vast stores of knowledge quickly and efficiently. The partnership was through NASA s Ames Research Center.

  18. The internet and intelligent machines: search engines, agents and robots

    International Nuclear Information System (INIS)

    The internet plays an important role in a growing number of medical applications. Finding relevant information is not always easy as the amount of available information on the Web is rising quickly. Even the best Search Engines can only collect links to a fraction of all existing Web pages. In addition, many of these indexed documents have been changed or deleted. The vast majority of information on the Web is not searchable with conventional methods. New search strategies, technologies and standards are combined in Intelligent Search Agents (ISA) an Robots, which can retrieve desired information in a specific approach. Conclusion: The article describes differences between ISAs and conventional Search Engines and how communication between Agents improves their ability to find information. Examples of existing ISAs are given and the possible influences on the current and future work in radiology is discussed. (orig.)

    NeQuick 2 is the latest version of the three-dimensional and time dependent ionospheric electron density model developed at the T/ICT4D (former ARPL) of the Abdus Salam International Centre for Theoretical Physics (ICTP) - Trieste, Italy and at the Institute for Geophysics, Astrophysics and Meteorology of the University of Graz, Austria. The purpose of this work is to identify possible limitations of the model. Therefore, the ability of NeQuick 2 in reproducing the vertical Total Electron Content (vTEC) derived from GPS observations using different input sources has been evaluated. The daily solar flux in 10.7 cm, the monthly smoothed solar flux and the hourly daily ionosonde derived F2 peak parameters, foF2 and hmF2, have been therefore used as model drivers to compute the vTEC at the relevant locations. Peak parameter values from three ionosonde stations (Ebre, El Arenosillo and Ramey) and GPS-derived vTEC data obtained from the corresponding co-located receivers (ebre, sfer, pur3) have been processed for the present work. The available data for the years 2000 and 2004, corresponding to high and moderate solar activity periods, have been considered to be able to estimate the model performance in a wide range of geophysical conditions. For each location, the data analysis has been based on statistical comparisons between experimental and retrieved vTEC. The results indicate that the differences between NeQuick 2-computed and GPS-derived vTEC exhibit well defined diurnal and seasonal patterns that depend on the location and period considered. On average, NeQuick 2 underestimates the vTEC during nighttime, mainly in the winter months and slightly during the summer months. In the daytime hours on the European locations, the model generally overestimates the vTEC in winter months, having an opposite behavior in the summer months. At PRJ18/pur3 location the NeQuick 2 response is more complex. During high solar activity, the daily difference between modeled and GPS

    It is promising to improve web image search results through exploiting the results0 visual contents for learning a binary classifier which is used to refine the results0 relevance degrees to the given query. This paper proposes an algorithm framework as a solution to this problem and investigates the key issue of training data selection under the framework. The training data selection process is divided into two stages: initial selection for triggering the classifier learning and dynamic selection in the iterations of classifier learning. We investigate two main ways of initial training data selection, including clustering based and ranking based, and compare automatic training data selection schemes with manual manner. Furthermore, support vector machines and the max-min pseudo-probability (MMP) based Bayesian classifier are employed to support image classification, respectively. By varying these factors in the framework, we implement eight algorithms and tested them on keyword based image search results from Google search engine. The experimental results confirm that how to select the training data from noisy search results is really a key issue in the problem considered in this paper and show that the proposed algorithm is effective to improve Google search results, especially at top ranks, thus is helpful to reduce the user labor in finding the desired images by browsing the ranking in depth. Even so, it is still worth meditative to make automatic training data selection scheme better towards perfect human annotation.

  3. Adding a Visualization Feature to Web Search Engines: It’s Time

    2008-11-11

    Since the first world wide web (WWW) search engine quietly entered our lives in 1994, the “information need” behind web searching has rapidly grown into a multi-billion dollar business that dominates the internet landscape, drives e-commerce traffic, propels global economy, and affects the lives of the whole human race. Today’s search engines are faster, smarter, and more powerful than those released just a few years ago. With the vast investment pouring into research and development by leading web technology providers and the intense emotion behind corporate slogans such as “win the web” or “take back the web,” I can’t help but ask why are we still using the very same “text-only” interface that was used 13 years ago to browse our search engine results pages (SERPs)? Why has the SERP interface technology lagged so far behind in the web evolution when the corresponding search technology has advanced so rapidly? In this article I explore some current SERP interface issues, suggest a simple but practical visual-based interface design approach, and argue why a visual approach can be a strong candidate for tomorrow’s SERP interface.

    Vaccination campaigns are one of the most important and successful public health programs ever undertaken. People who want to learn about vaccines in order to make an informed decision on whether to vaccinate are faced with a wealth of information on the Internet, both for and against vaccinations. In this paper we develop an automated way to score Internet search queries and web pages as to the likelihood that a person making these queries or reading those pages would decide to vaccinate. We apply this method to data from a major Internet search engine, while people seek information about the Measles, Mumps and Rubella (MMR) vaccine. We show that our method is accurate, and use it to learn about the information acquisition process of people. Our results show that people who are pro-vaccination as well as people who are anti-vaccination seek similar information, but browsing this information has differing effect on their future browsing. These findings demonstrate the need for health authorities to tailor their information according to the current stance of users. PMID:25954435

  7. Div-BLAST: diversification of sequence search results.

    Directory of Open Access Journals (Sweden)

    Elif Eser

    Full Text Available Sequence similarity tools, such as BLAST, seek sequences most similar to a query from a database of sequences. They return results significantly similar to the query sequence and that are typically highly similar to each other. Most sequence analysis tasks in bioinformatics require an exploratory approach, where the initial results guide the user to new searches. However, diversity has not yet been considered an integral component of sequence search tools for this discipline. Some redundancy can be avoided by introducing non-redundancy during database construction, but it is not feasible to dynamically set a level of non-redundancy tailored to a query sequence. We introduce the problem of diverse search and browsing in sequence databases that produce non-redundant results optimized for any given query. We define diversity measures for sequences and propose methods to obtain diverse results extracted from current sequence similarity search tools. We also propose a new measure to evaluate the diversity of a set of sequences that is returned as a result of a sequence similarity query. We evaluate the effectiveness of the proposed methods in post-processing BLAST and PSI-BLAST results. We also assess the functional diversity of the returned results based on available Gene Ontology annotations. Additionally, we include a comparison with a current redundancy elimination tool, CD-HIT. Our experiments show that the proposed methods are able to achieve more diverse yet significant result sets compared to static non-redundancy approaches. In both sequence-based and functional diversity evaluation, the proposed diversification methods significantly outperform original BLAST results and other baselines. A web based tool implementing the proposed methods, Div-BLAST, can be accessed at cedar.cs.bilkent.edu.tr/Div-BLAST.

    AIM: To combine ultrasound-guided fine-needle aspiration (US-FNA) and Liu (Riu) stain to make a quick study on liver tumor lesions.METHODS: Two hundred and twenty-eight aspirations from 232 patients were completely studied. The operator himself made the quick cytodiagnosis of US-FNA smear stained by Liu method within thirty minutes. The US-FNA specimen was also sent to the pathological department for cytological study and cellblock histology. The result of our Liu-stain quick cytodiagnosis in each patient was confirmed by the final cytopathological diagnosis from pathological report.RESULTS: Among 228 samples, the quick cytodiagnosis revealed 146 malignancies, 81 benign lesions and one inadequate specimen. Cytopathological diagnosis from the pathological department revealed 150 malignancies,and 78 benign lesions. Four well-differentiated hepatocellular carcinomas (HCCs) were under-diagnosed by quick cytodiagnosis as benign and 3 benign lesions were over-diagnosed as well-differentiated HCCs. Compared with cytopathological diagnosis, quick cytodiagnosis correctly diagnosed 143 malignancies and 77 benign lesions. Except for the one inadequate specimen in quick cytodiagnosis, the accuracy of quick cytodiagnosis was 96.9% (220/227), and its sensitivity, specificity and positive and negative predictive values were 97.9%, 95.1%,97.3% and 96.3%, respectively.CONCLUSION: Liu-stain quick cytodiagnosis is a fast,convenient, safe and effective method for hepatologists in clinic practice to diagnose liver tumor. In few cases of well-differentiated HCC, Liu-stain quick cytodiagnosis has its limitation.

  9. Carbon Allocation into Different Fine-Root Classes of Young Abies alba Trees Is Affected More by Phenology than by Simulated Browsing.

    Science.gov (United States)

    Endrulat, Tina; Buchmann, Nina; Brunner, Ivano

    2016-01-01

    Abies alba (European silver fir) was used to investigate possible effects of simulated browsing on C allocation belowground by 13CO2 pulse-labelling at spring, summer or autumn, and by harvesting the trees at the same time point of the labelling or at a later season for biomass and for 13C-allocation into the fine-root system. Before budburst in spring, the leader shoots and 50% of all lateral shoots of half of the investigated 5-year old Abies alba saplings were clipped to simulate browsing. At harvest, different fine-root classes were separated, and starch as an important storage compartment was analysed for concentrations. The phenology had a strong effect on the allocation of the 13C-label from shoots to roots. In spring, shoots did not supply the fine-roots with high amounts of the 13C-label, because the fine-roots contained less than 1% of the applied 13C. In summer and autumn, however, shoots allocated relatively high amounts of the 13C-label to the fine roots. The incorporation of the 13C-label as structural C or as starch into the roots is strongly dependent on the root type and the root diameter. In newly formed fine roots, 3-5% of the applied 13C was incorporated, whereas 1-3% in the ≤0.5 mm root class and 1-1.5% in the >0.5-1.0 mm root class were recorded. Highest 13C-enrichment in the starch was recorded in the newly formed fine roots in autumn. The clipping treatment had a significant positive effect on the amount of allocated 13C-label to the fine roots after the spring labelling, with high relative 13C-contents observed in the ≤0.5 mm and the >0.5-1.0 mm fine-root classes of clipped trees. No effects of the clipping were observed after summer and autumn labelling in the 13C-allocation patterns. Overall, our data imply that the season of C assimilation and, thus, the phenology of trees is the main determinant of the C allocation from shoots to roots and is clearly more important than browsing.

  11. Handbook for quick cost estimates. A method for developing quick approximate estimates of costs for generic actions for nuclear power plants

    International Nuclear Information System (INIS)

    This document is a supplement to a ''Handbook for Cost Estimating'' (NUREG/CR-3971) and provides specific guidance for developing ''quick'' approximate estimates of the cost of implementing generic regulatory requirements for nuclear power plants. A method is presented for relating the known construction costs for new nuclear power plants (as contained in the Energy Economic Data Base) to the cost of performing similar work, on a back-fit basis, at existing plants. Cost factors are presented to account for variations in such important cost areas as construction labor productivity, engineering and quality assurance, replacement energy, reworking of existing features, and regional variations in the cost of materials and labor. Other cost categories addressed in this handbook include those for changes in plant operating personnel and plant documents, licensee costs, NRC costs, and costs for other government agencies. Data sheets, worksheets, and appropriate cost algorithms are included to guide the user through preparation of rough estimates. A sample estimate is prepared using the method and the estimating tools provided

    Because laboratory tests are expensive and time-consuming and may not be available to farmers,soil nitrate quick tests are required for optimal nitrogen management strategies in China to increase nitrogen use effciency and to reduce nitrogen losses.A total of 328 soil samples were collected at different soil depths from 225 sites in China,which covered a wide range of clinatic and geographic regions,soil types,croplands and soil textures,to evaluate the suitability of a quick reflectometer test method for analysing soil NO3--N in a wide range of soil NO3- concentrations,soil types and cropping systems in China,mainly by comparison ofsoil NO3--N assessed by a quick-test method (a reflectometer) and a standard laboratory method,i.e.,high performance liquid chromatography (HPLC).The reflectometer showed excellent agreement with the laboratory HPLC method with regard to soil nitrate contents for all analysed soil samples.The linear regression had slopes of 1±0.08 and intercepts of ± 1.38 mg NO3--N L-1 among different soil types and croplands.Compared with the 1∶1 lines,the regression analysis for each soil type showed statistically significant but small differences in slope; the relative difference between the values measured using the two analytical systems varied from -8% to 6%,and there were no differences in intercept except for paddy soil.The reflectometer showed adequate,statistically significant precision in determining soil nitrate contents,and it could therefore be directly used instead of the laboratory methods for soil NO3--N measurement in China.

    QUICKFLEX's patent pending and revolutionary Quick Qard Technology (QQT) Reconfigurable Computing (RC) architecture approaches RC from an Operating System (OS) systems viewpoint, rather than from the perspective of any one particular application. As such, many problems important to integrating reconfigurable logic into the OS are solved. These problems would otherwise prevent RC from easily being used in a general-purpose mainstream market. The differences between QQT and other RC board methods of use is not so much in the RC hardware and boards, but in the way the RC hardware is utilized as part of a system.

  1. Benchmarking the codes VORPAL, OSIRIS, and QuickPIC with Laser Wakefield Acceleration Simulations

    International Nuclear Information System (INIS)

    Three-dimensional laser wakefield acceleration (LWFA) simulations have recently been performed to benchmark the commonly used particle-in-cell (PIC) codes VORPAL, OSIRIS, and QuickPIC. The simulations were run in parallel on over 100 processors, using parameters relevant to LWFA with ultra-short Ti-Sapphire laser pulses propagating in hydrogen gas. Both first-order and second-order particle shapes were employed. We present the results of this benchmarking exercise, and show that accelerating gradients from full PIC agree for all values of a0 and that full and reduced PIC agree well for values of a0 approaching 4.

    International Nuclear Information System (INIS)

    An analytical quick-test method was developed to determine iodide and iodate ions in aqueous solutions using solid phase extraction cartridges for sample preparation. Work was focussed on finding simple, but efficient conditions for quantitative separation of iodate and iodide. Iodine amounts were then determined by standard methods. Ion-exchange absorbers in cartridge form were used. Selectivity and yield of the species separation were studied at pH value of 5-10 and various solution compositions using 131I radioactive tracer. The electrolytes used were diluted alkaline, nitrate and boric acid-borate solutions. Application to nuclear reactor cooling water analysis or environmental investigations and monitoring is proposed.

    Retrieval of basic soil parameters such as bulk density and soil moisture from soil samples is a costly and time-consuming activity. Although indirect methods (heat or electromagnetic probes, radar backscatter, etc) are abundant, field truth measurement of soil parameters will remain important, if only to calibrate these other methods. We present a quick, field mountable setup to make 3D scans of surfaces up to 30 x 30 cm using a Kinect 3D scanner. By making scans before and after samples are taken, parameters such as bulk density and moisture content can easily be calculated.

    Seismic intensity map which reflects the actual situation of destruction in a certain area after the earthquake, and it is of great significance in guiding relief work and assessing damage loss. Based on cloud monitoring method proposed, we developed software, which can quickly investigate the seismic intensity distribution and draw the intensity map after the earthquake using the big data collected by individual smart phone questionnaire in earthquake zone. According to seismic attenuation law, we generated some seismic intensity values to test our system and successfully drawn out of the seismic intensity map.

  6. Validation of the Dutch version of the quick mild cognitive impairment screen (Qmci-D).

    Differentiating mild cognitive impairment (MCI) from dementia is important, as treatment options differ. There are few short (<5 min) but accurate screening tools that discriminate between MCI, normal cognition (NC) and dementia, in the Dutch language. The Quick Mild Cognitive Impairment (Qmci) screen is sensitive and specific in differentiating MCI from NC and mild dementia. Given this, we adapted the Qmci for use in Dutch-language countries and validated the Dutch version, the Qmci-D, against the Dutch translation of the Standardised Mini-Mental State Examination (SMMSE-D).

    2013-09-01

    Existing methods of local search mostly focus on how to reach optimal solution. However, in some emergency situations, search time is the hard constraint for job shop scheduling problem while optimal solution is not necessary. In this situation, the existing method of local search is not fast enough. This paper presents an emergency local search(ELS) approach which can reach feasible and nearly optimal solution in limited search time. The ELS approach is desirable for the aforementioned emergency situations where search time is limited and a nearly optimal solution is sufficient, which consists of three phases. Firstly, in order to reach a feasible and nearly optimal solution, infeasible solutions are repaired and a repair technique named group repair is proposed. Secondly, in order to save time, the amount of local search moves need to be reduced and this is achieved by a quickly search method named critical path search(CPS). Finally, CPS sometimes stops at a solution far from the optimal one. In order to jump out the search dilemma of CPS, a jump technique based on critical part is used to improve CPS. Furthermore, the schedule system based on ELS has been developed and experiments based on this system completed on the computer of Intel Pentium(R) 2.93 GHz. The experimental result shows that the optimal solutions of small scale instances are reached in 2 s, and the nearly optimal solutions of large scale instances are reached in 4 s. The proposed ELS approach can stably reach nearly optimal solutions with manageable search time, and can be applied on some emergency situations.

    2000-01-01

    In 1994 and 1995 leaves from eight browse feeds, containing tannins in different amounts (BF), were fed to West African Dwarf Sheep in Benin to evaluate their impact on Clostridium perfringens in the intestinal tract. An inhibitory impact of various BF on the growth of C. perfringens was assessed in in-vitro assays before, and thus a potential use of these leaves as a preventive diet against C. perfringens enterotoxemia in small ruminants was assumed. Surprisingly, an inhibitory impact of the BF on the shedding of C. perfringens in the feces of West African Dwarf Sheep could not be shown in seven of the eight BF examined. However, the pattern of inhibition of unlike C. perfringens toxovars may differ and a selective inhibitory impact of the BF Dialium guineense on C. perfringens toxovar D may be assumed.

    The enormous amount of solar data, a result of new observational missions, needs to be stored and retrieved intelligently. Existing systems (e.g., the Science Archive of the Solar and Heliospheric Observatory (SOHO); soho.nascom.nasa.go) manage solar data merely using metadata (e.g., the time that images were taken) or other programmatic information. As a result, such systems can only support very primitive queries (e.g., images taken in June 2009). From such search results, scientists have to manually select their needed data for further analysis. On the other hand, solar data, either raw or processed, are often associated with semantic information such as the active regions in an image and corresponding text annotations. Such semantic knowledge can provide much more insights to the data and can help scientists quickly find data that are related to a specific research goal or topic (e.g., solar flares or coronal mass ejections). A solar data management system should be able to intelligently utilize such relevant semantic data to facilitate solar data retrieval, and ultimately saves investigators valuable time. In this work, we build a prototype for the intelligent retrieval and exploration of solar data by utilizing the semantic knowledge associated with raw or processed solar data. The core of this prototype is a "query processing” component that utilizes a unified index technique to support both simple basic queries (e.g., images taken in 2007) over the metadata and intelligent topic queries (e.g., image regions related to "Solar Flares” in 2007) over other complicated contents. This component leverages different types of data (especially semantic information) to improve the search accuracy. Besides this, another facilitating component is designed to provide user-friendly result exploration functionalities when the "query processing” component returns a set of query results.

    Full Text Available Tuberculosis is still a global emergency and a major public health problem, in some cases related to the appearance of strains of multi drug resistance (MDR and extensive drug resistance (XDR Mycobacterium tuberculosis complex.The correct determination of antibiotic sensitivity profiles is therefore crucial to carry out appropriate treatment aimed to decrease the infectivity of each patient and to reduce mortality. The poor adherence to treatment by the patient or the use of therapies based on a single drug, as a result of incorrect requirements, promote the development of drug-resistance. Have some time on the market of molecular diagnostic tests that allow, quickly and directly from biological sample to search for resistance genes some key drugs of anti-TB therapy (Rifampicin and Isoniazid. One of the tests in question is the Genotype MTBDRplus ver 2.0 which can reveal the presence of genes for resistance to Isoniazid (INH and Rifampin (RMP.The loci analyzed are those corresponding to the rpoB gene for rifampicin, katG and inhA for isoniazid. Our study is based on the analysis of 83 strains of tubercular Mycobacteria identified and isolated from patients with tuberculosis disease and subjected to the tests sensitivity, searching for mutations and phenotypic susceptibility testing for Rifampicin and Isoniazid.The comparison of the results has shown that the results obtained using the Genotype MTBDRplus ver 2.0 test, were similar to the results obtained by the traditional susceptibility testing.

    Full Text Available We studied the habitat use of mountain nyala Tragelaphus buxtoni in the northern edge of the Bale Mountains National Park, Ethiopia. The aims of this study were to: (1 measure and quantify habitat-specific stem bite diameters of mountain nyala foraging on common natural plant species in two major habitat types (i.e. grasslands versus woodlands, and (2 quantify the bite rates (number of bites per minute and the activity time budgets of mountain nyala as functions of habitat type and sex-age category. We randomly laid out three transects in each habitat type. Following each transect, through focal animal observations, we assessed and quantified stem diameters at point of browse (dpb, bite rates, and time budgets of mountain nyala in grasslands versus woodlands. Stem dpb provide a measure of natural giving-up densities (GUDs and can be used to assess foraging costs and efficiencies, with greater stem dpb corresponding to lower costs and greater efficiencies. The results showed that stem dpb, bite rates, induced vigilance, and proportion of time spent in feeding differed between habitats. In particular, mountain nyala had greater stem dpb, higher bite rates, and spent a greater proportion of their time in feeding and less in induced vigilance in the grasslands. In addition, adult females had the highest bite rates, and the browse species Solanum marginatum had the greatest stem dpb. Generally, grasslands provide the mountain nyala with several advantages over the woodlands, including offering lower foraging costs, greater safety, and more time for foraging. The study advocates how behavioural indicators and natural GUDs are used to examine the habitat use of the endangered mountain nyala through applying non-invasive techniques. We conclude that the resulting measures are helpful for guiding conservation and management efforts and could be applicable to a number of endangered wildlife species including the mountain nyala [Current Zoology 59 (6 : 707

    The haematological and biochemical parameters of 24 growing Red Sokoto bucks (9.00 ± 0.25 kg body weight) fed threshed sorghum top (TST) with or without five different browse plant foliage Afzelia africana (AA), Daniellia oliveri (DO), Piliostigma thonningii (PT), Pterocarpus erinaceus (PE) and Annona senegalensis (AS) supplements were studied using a completely randomized design. All haematological parameters were (P < 0.05) lower in TST-fed goats compared with TST-supplemented goats, except for mean corpuscular haemoglobin concentration (MCHC), lymphocytes and monocytes which did not follow a particular pattern. Packed cell volume, haemoglobin and monocytes were higher for AA-supplemented goats while MCHC was reduced relative to other supplements (P < 0.05). White blood cell counts were increased in DO lambs compared to other supplements (P < 0.05). Serum proteins, creatinine, alanine transaminase and alkaline phosphate were reduced in TST compared with the supplements (P < 0.05). Cholesterol was higher for PT and AA than other diets (P < 0.05). Aspartate transaminase was reduced in TST goats relative to the supplements (P < 0.05). Except for potassium which was reduced in AS (P < 0.05), all serum major minerals were similar among diets. Results indicate that the entire browse fodder are good supplements to low-quality TST, though A. africana appears to have a better supplementary effect on haematological and biochemical parameters of the goats.

    Search for external knowledge is vital for firms' innovative activities. To understand search, we propose two knowledge search dimensions: search space (local or distant) and search heuristics (experiential or cognitive). Combining these two dimensions, we distinguish four search paths - situated paths, analogical paths, sophisticated paths, and scientific paths - which respond to recent calls to move beyond "where to search" and to investigate the connection with "how to search." Also, we hi...

    2011-05-01

    The purpose of this study was to evaluate the effects of the speed, agility, quickness (SAQ) training method on power performance in soccer players. Soccer players were assigned randomly to 2 groups: experimental group (EG; n = 50) and control group (n = 50). Power performance was assessed by a test of quickness--the 5-m sprint, a test of acceleration--the 10-m sprint, tests of maximal speed--the 20- and the 30-m sprint along with Bosco jump tests--squat jump, countermovement jump (CMJ), maximal CMJ, and continuous jumps performed with legs extended. The initial testing procedure took place at the beginning of the in-season period. The 8-week specific SAQ training program was implemented after which final testing took place. The results of the 2-way analysis of variance indicated that the EG improved significantly (p SAQ training program appears to be an effective way of improving some segments of power performance in young soccer players during the in-season period. Soccer coaches could use this information in the process of planning in-season training. Without proper planning of the SAQ training, soccer players will most likely be confronted with decrease in power performance during in-season period. PMID:21522073

  4. Quick Local Repair Scheme using Adaptive Promiscuous Mode in Mobile Ad Hoc Networks

    Directory of Open Access Journals (Sweden)

    2006-05-01

    Full Text Available In mobile ad hoc networks (MANETs, there is frequently disconnected a route consisting of multi- hop from a source to a destination because of the dynamic nature such as the topology change caused by nodes’ mobility. To overcome this situation, existing routing protocols for MANETs have performed route repair scheme to repair the disconnected route. However, existing reactive routing protocols have the problem which is that a source node unnecessarily performs re-discovers the whole path when just one node moves, even if the rest of path needs not to be re-arranged. Therefore, the time for re-discovery of the whole path may often take too long. To solve the problem, we propose a new local repair scheme using promiscuous mode. Our scheme is mainly composed of two parts: adaptive promiscuous mode and quick local repair scheme. Adaptive promiscuous mode is to repeat the switching processes between promiscuous mode and nonpromiscuous mode to overcome energy limit caused by using promiscuous mode in overall time and quick local repair scheme is to fast perform the local re-route discovery process with the information of the active connection in the local area acquired by promiscuous mode. With simulation in the various number of connection, We demonstrate the better network performances achieved with the proposed schemes as compared with AODV as reference model that do not provide local repair scheme.

  5. Quick, portable toxicity testing of marine or terrigenous fluids, sediments, or chemicals with bioluminescent organism

    International Nuclear Information System (INIS)

    A hand-held, battery-operated instrument, which measures bioluminescence inhibition of the microscopic marine dinoflagellate Pyrocystis lunula, is capable of field-testing substances for toxicity. The organism is sensitive to ppb of strong toxicants. It tolerates some solvents in concentrations necessary for testing lipophylic samples. A test consumes only micrograms of sample. This method requires no adjustments for salinity, pH, color, or turbidity. It has been used successfully to test oil-well drilling fluids, brines produced with oil, waters and sediments from streams and lakes and petroleum-plant effluents containing contaminants such as benzene. The test is non-specific; however, if the substance is known, the end-point effects a direct measurement of its concentration. One-hour toxicity screening tests in the field produce results comparable to the standard four-hour laboratory test. Keeping the sample in the dark during incubation and testing, together with shortness of the overall procedure, eliminates anomalies from light-sensitive substances. Day-to-day variation, as well as among test replicates, is less than 10%. This quick method yields results comparable with a quick test that uses Photobacterium phosphoria, and with 96-hour tests that use Mysidopsis bahia, Artemia salina, Gonyaulax polyedra, Pimephales promelas, Ceriodaphnia dubia, and Cyprinodon variegatus

    The Pacific Northwest Laboratory (PNL) prepared this report under contract to the Bonneville Power Administration (Bonneville), as part of the Resource Supply Expansion Project (RSEP). RSEP is a regional program instituted by Bonneville to expand conservation and renewable generation options available to resource planners and utilities. Resource alternatives are increased by RSEP through demonstration projects designed in a collaborative process that targets specific barriers to resource development including institutional, market, and reliability barriers. RSEP was launched with several projects that were designed and implemented quickly in 1992 to lay a foundation for future collaboration. The purpose of this report is to introduce the goal and structure of RSEP and to describe the so-called ``Quick Start`` RSEP projects in Phase One of RSEP. This description includes a preliminary estimate of the energy savings and/or other expected impacts of RSEP projects funded in FY 1992 and 1993. Similar estimates are also included for Bonneville projects to confirm wind and geothermal generation potential. Bonneville`s Geothermal Confirmation Agenda preceded implementation of RSEP, although it has a similar objective and collaborative approach.

  7. Aqueous sodium borohydride induced thermally stable porous zirconium oxide for quick removal of lead ions

    2016-03-01

    Aqueous sodium borohydride (NaBH4) is well known for its reducing property and well-established for the development of metal nanoparticles through reduction method. In contrary, this research paper discloses the importance of aqueous NaBH4 as a precipitating agent towards development of porous zirconium oxide. The boron species present in aqueous NaBH4 play an active role during gelation as well as phase separated out in the form of boron complex during precipitation, which helps to form boron free zirconium hydroxide [Zr(OH)4] in the as-synthesized condition. Evolved in-situ hydrogen (H2) gas-bubbles also play an important role to develop as-synthesized loose zirconium hydroxide and the presence of intra-particle voids in the loose zirconium hydroxide help to develop porous zirconium oxide during calcination process. Without any surface modification, this porous zirconium oxide quickly adsorbs almost hundred percentages of toxic lead ions from water solution within 15 minutes at normal pH condition. Adsorption kinetic models suggest that the adsorption process was surface reaction controlled chemisorption. Quick adsorption was governed by surface diffusion process and the adsorption kinetic was limited by pore diffusion. Five cycles of adsorption-desorption result suggests that the porous zirconium oxide can be reused efficiently for removal of Pb (II) ions from aqueous solution.

    How to achieve fast and stable startup of shortcut nitrification has a very important practical value for treatment of low C/N ratio wastewater. Thus, the quick start-up and sustaining of shortcut nitrification were investigated in continuous flow reactor targeting at the current situation of urban wastewater treatment plant using a continuous flow process. The results showed that quick start-up of shortcut nitrification could be successfully achieved in a continuous flow reactor after 60 days' operation with intermittent aeration and controlling of three stages of stop/aeration time (15 min/45 min, 45 min/45 min and 30 min/30 min). The nitrification rates could reach 90% or 95% respectively, while influent ammonia concentrations were 50 or 100 mg · L⁻¹ with stop/aeration time of 30 min/30 min. In addition, intermittent aeration could inhibit the activity of nitrite oxidizing bacteria (NOB), while short hydraulic retention time (HRT) may wash out NOB. And a combined use of both measures was beneficial to sustain shortcut nitrification. PMID:27548971

    2012-01-01

    Actual social networks (like Facebook, Twitter, Linkedin, ...) need to deal with vagueness on ontological indeterminacy. In this paper is analyzed the prototyping of a faceted semantic search for personalized social search using the "joint meaning" in a community environment. User researches in a "collaborative" environment defined by folksonomies can be supported by the most common features on the faceted semantic search. A solution for the context-aware personalized search is based on "joint meaning" understood as a joint construal of the creators of the contents and the user of the contents using the faced taxonomy with the Semantic Web. A proof-of concept prototype shows how the proposed methodological approach can also be applied to existing presentation components, built with different languages and/or component technologies.

    2009-01-01

    In this paper we present an approach for supporting users in the difficult task of searching for video. We use collaborative feedback mined from the interactions of earlier users of a video search system to help users in their current search tasks. Our objective is to improve the quality of the results that users find, and in doing so also assist users to explore a large and complex information space. It is hoped that this will lead to them considering search options that they may not have considered otherwise. We performed a user centred evaluation. The results of our evaluation indicate that we achieved our goals, the performance of the users in finding relevant video clips was enhanced with our system; users were able to explore the collection of video clips more and users demonstrated a preference for our system that provided recommendations.
