Using users' comments from a movie information site, we develop a movie classification system based on Naive Bayes method. We evaluate the classification results with the genre for each movie classified by IMDb. For the objective evaluation of the classification precision, we employed the average precision. The average precision is about 0.7 in 1—fold cross-validation. When we look into the movie classification from this experiment, we notice that even in the case in which the existing genre classification and machine classification differ, the machine classifications are valuable or even more persuasive.

QUICker Connection Establishment with Out-Of-Band Validation Tokens

QUIC is a secure transport protocol that improves the performance of HTTPS. An initial QUIC handshake that enforces a strict validation of the client’s source address requires two round-trips. In this work, we extend QUIC’s address validation mechanism by an out-of-band validation token to save one round-trip time during the initial handshake. The proposed token allows sharing an address validation between the QUIC server and trusted entities issuing these tokens. This saves a round-trip time for the address validation. Furthermore, we propose distribution mechanisms for these tokens using DNS resolvers and QUIC connections to other hostnames. Our proposal can save up to 50% of the delay overhead of an initial QUIC handshake. Furthermore, our analytical results indicate that 363.6 ms in total can be saved for all connections required to retrieve an average website, if a round-trip time of 90 ms is assumed.

View of MapReduce: Programming model, methods, and its Applications

Abstract In recent years, cloud computing as a new Internet application pattern is changing the way that people access information and services. And, MapReduce, as a large-scale data processing and distributed computing model, attracts wide attention from academia and industry, and plays a decisive role in the development of cloud computing. Aim to current status of MapReduce applications in cloud computing, this paper describes the MapReduce programming model and operation mechanism, and gives a typical application based on MapReduce. On this basis, several challenges and ideas for MapReduce are proposed to offer some references for researchers and users who concern on cloud computing and MapReduce.
The effect of resveratrol on insulin resistance, metabolic syndrome and hepatic oxidative stress in fructose- fed rats

Background/Aim: Metabolic syndrome and oxidative stress are common complications of type 2 diabetes mellitus. The aim of this work was to study the effect of resveratrol, a widely used nutritional supplement on insulin sensitivity, some metabolic parameters and hepatic oxidative stress in high fructose- fed rats. Material & methods : Male Wister rats (180-200g) were divided into 3 groups 10 per each. G1: Control group was fed 65% corn starch diet. G2: Fructose-fed insulin resistant group (HFD) was fed 65% fructose diet. G3: (HFD + Resveratrol) was fed with 65% fructose along with a single dose of 10 mg/kg/day of resveratrol orally through intra gastric tube for a period of 8 weeks. Results: At the end of the feeding schedule, HFD group had significant hyperglycemia, hyperinsulinemia and insulin resistance as evident by HOMA IR. There were significant increase in triglyceride and nitric oxide levels as well as in hepatic ThioBabituric Acid Reactive Substance (TBARS) and significant decrease in vitamin C in HFD group compared with control group. Administration of resveratrol significantly improved the altered metabolic parameters, hepatic oxidative stress parameters and significantly reduced inflammatory markers (Monocyte Chemoattractant Protein -1(MCP-1), Tumor Necrosis Factorα (TNFα) and Regulated on Activation Normal T cells Expressed and Secreted (RANTES). Conclusion : Resveratrol supplementation might attenuate the insulin resistance, hepatic oxidative stress state and inflammatory state in metabolic syndrome.
Research On Image Mining Based On Formal Concept Analysis

The traditional recommendation algorithms of image tagging ignore the diversity between the visual content information and the tags recommended, which causes the recommended results have the problem of tag ambiguity, tag redundancy and so on. Therefore, this paper proposes the recommendation algorithm of image tagging based on relevance and diversity. The algorithm defines the relevance and diversity of a label set, and selects a label set which can reasonably balance the relevance and diversity to recommend to the user. The experimental results show that this algorithm improves the relevance between the recommended results and the image, and makes the recommended results be able to reflect the image content thoroughly at the same time.
STL Model Segmentation for Multi-Axis Machining Operations Planning

AbstractThis paper aims a segmentation procedure for an STL model on behalf of an automated multi-axis milling operations planning system. The STL file that represents the existing product model has to be segmented into regions suited for the planning of milling operations. Originating from the domain of rapid prototyping, the STL data format nowadays appears in other domains of manufacturing. Within machining, STL is being used for three-axis tool path generation and some prototype systems are able to generate five-axis tool paths directly on STL. The algorithm presented in this paper is situated in the step prior to tool path generation. The dedicated segmentation algorithm consists of a phase of sharp edge detection followed by a workpiece setup dependent segmentation. The dynamically variable nature of this segmentation scheme is stressed.
Capacity of loss-free queue with QoS constraints

In this paper, we propose a method to analyze the capacity of a network node. The concept of channel capacity in Shannon information theory is used. We focus on the single node case, with loss-free queue. Also, the QoS constraints of the traffic are taken into account during our analysis. The capacity of a M/M/1 queue is given in this paper with the constraints of packet delay.
Response Possibilities to the Boothroyd (Ab) Word Lists

An examination of the phonemic error patterns made by particular subjects in response to speech audiometry is capable of providing useful information on the way in which that subject categorises speech elements. Since most responses are in the form of real words extracted from the subject's lexicon it is essential to estimate the possibility of occurrence of particular phonemic errors before the overall error patterns can be interpreted in a meaningful way. A set of such possibility matrices for the Boothroyd (AB) word lists is presented.
Verb Noun Construction MWE Token Classification

We address the problem of classifying multiword expression tokens in running text. We focus our study on Verb-Noun Constructions (VNC) that vary in their idiomaticity depending on context. VNC tokens are classified as either idiomatic or literal. We present a supervised learning approach to the problem. We experiment with different features. Our approach yields the best results to date on MWE classification combining different linguistically motivated features, the overall performance yields an F-measure of 84.58% corresponding to an F-measure of 89.96% for idiomaticity identification and classification and 62.03% for literal identification and classification.
Adaptive compensatory of nonlinear time varying torque disturbances in rigid robots

This paper presents a new approach to the control of rigid robots when actuator dynamics, nonlinearities (e.g. saturation) and Coulomb friction, are relevant. An adaptive like algorithm is used in order to obtain the desired trajectory tracking in the presence of unknown, nonlinear, time varying torque disturbances acting on the robot. <<ETX>>
NEW NEUTRON-CAPTURE MEASUREMENTS IN 23 OPEN CLUSTERS. I. THE r-PROCESS

Neutron-capture elements, those with Z > 35, are the least well understood in terms of nucleosynthesis and formation environments. The rapid neutron-capture, or r-process, elements are formed in the environments and/or remnants of massive stars, while the slow neutron-capture, or s-process, elements are primarily formed in low-mass AGB stars. These elements can provide much information about Galactic star formation and enrichment, but observational data are limited. We have assembled a sample of 68 stars in 23 open clusters that we use to probe abundance trends for six neutron-capture elements (Eu, Gd, Dy, Mo, Pr, and Nd) with cluster age and location in the disk of the Galaxy. In order to keep our analysis as homogeneous as possible, we use an automated synthesis fitting program, which also enables us to measure multiple (3–10) lines for each element. We find that the pure r-process elements (Eu, Gd, and Dy) have positive trends with increasing cluster age, while the mixed r- and s-process elements (Mo, Pr, and Nd) have insignificant trends consistent with zero. Pr, Nd, Eu, Gd, and Dy have similar, slight (although mostly statistically significant) gradients of ∼0.04 dex kpc−1. The mixed elements also appear to have nonlinear relationships with RGC.
STELLAR MASS VERSUS STELLAR VELOCITY DISPERSION: WHICH IS BETTER FOR LINKING GALAXIES TO THEIR DARK MATTER HALOS?

It was recently suggested that compared to its stellar mass (M*), the central stellar velocity dispersion (σ*) of a galaxy might be a better indicator for its host dark matter halo mass. Here we test this hypothesis by estimating the dark matter halo mass for central galaxies in groups as a function of M* and σ*. For this we have estimated the redshift-space cross-correlation function (CCF) between the central galaxies at given M* and σ* and a reference galaxy sample, from which we determine both the projected CCF, wp(rp), and the velocity dispersion profile. A halo mass is then obtained from the average velocity dispersion within the virial radius. At fixed M*, we find very weak or no correlation between halo mass and σ*. In contrast, strong mass dependence is clearly seen even when σ* is limited to a narrow range. Our results thus firmly demonstrate that the stellar mass of central galaxies is still a good (if not the best) indicator for dark matter halo mass, better than the stellar velocity dispersion. The dependence of galaxy clustering on σ* at fixed M*, as recently discovered by Wake et al., may be attributed to satellite galaxies, for which the tidal stripping occurring within halos has stronger effect on stellar mass than on central stellar velocity dispersion.
Spatial outlier detection with multiple attributes weighted

Spatial outliers are the spatial objects with distinct features from their surrounding neighbors. Detection of spatial outliers helps reveal valuable information from large spatial data sets. In many real applications, spatial objects can not be simply abstracted as isolated points. They have different boundary, size, volume, and location. These spatial properties affect the impact of a spatial object on its neighbors and should be taken into consideration. In this paper, we propose two spatial outlier detection methods which integrate the impact of spatial properties to the outlierness measurement. Experimental results on a real data set demonstrate the effectiveness of the proposed algorithms.
Improving the performance of multi-layer perceptrons where limited training data are available for some classes

The standard multi-layer perceptron (MLP) training algorithm implicitly assumes that equal numbers of examples are available to train each of the network classes. However, in many condition monitoring and fault diagnosis (CMFD) systems, data representing fault conditions can only be obtained with great difficulty: as a result, training classes may vary greatly in size, and the overall performance of an MLP classifier may be comparatively poor. We describe two techniques which can help ameliorate the impact of unequal training set sizes. We demonstrate the effectiveness of these techniques using simulated fault data representative of that found in a broad class of CMFD problems.
Mediators of the effectiveness of online courses

A three-year field study of 17 courses, part of an undergraduate degree in information systems, compared the process and outcomes of three modes of delivery: totally online via asynchronous learning networks, traditional face-to-face courses, and sections using a mix of traditional and online activities. There were no significant differences in perceived learning by students associated with mode of delivery. Group collaboration and access to professors was perceived to be highest in mixed-mode sections, while convenience was rated highest in the distance sections. For online courses, there was generally a significant relationship between the hypothesized mediators (active participation, motivation, collaboration, access to the professor, and convenience) and perceived learning. Overall, the results of this study show that outcomes of online courses improved when professors structured them to support the growth of a learning community, by being available online to interact with students, and by using collaborative learning strategies.
Effects of Online Academic Lectures on ESL Listening Comprehension, Incidental Vocabulary Acquisition, and Strategy Use

This paper investigates how authentic web-delivered video can inform ESL online instruction and enhance the incidental acquisition of vocabulary and listening comprehension. A total of 24 adult learners of English as a Second Language enrolled in a listening comprehension class at a major Midwestern university participated in the study. The participants completed pre-, post-, and delayed vocabulary post-tests, a computer-assisted language learning (CALL) activity including an academic lecture on horticulture, and a questionnaire. In addition to the performance measures, a screen capturing application, Camtasia Recorder (2001), was used for nine learners to document actual learner-CALL activity interaction, which was used as the basis for a post-task interview. The results suggest that incidental vocabulary acquisition occurs and that lower-level learners are more likely to resort to the wrong aspects of the lecture in responding to comprehension questions. While engaged in the online CALL activity, advanced learners exhibited both metacognitive and cognitive learning strategies. Intermediate and lower-level learners mostly made use of cognitive strategies. Female learners used more strategies than male learners and female learners preferred cognitive strategies while male learners used more metacognitive than cognitive strategies.
Scalable Bayesian Inference for Population Markov Jump Processes

Bayesian inference for Markov jump processes (MJPs) where available observations relate to either system states or jumps typically relies on data-augmentation Markov Chain Monte Carlo. State-of-the-art developments involve representing MJP paths with auxiliary candidate jump times that are later thinned. However, these algorithms are i) unfeasible in situations involving large or infinite capacity systems and ii) not amenable for all observation types. In this paper we establish and present a general data-augmentation framework for population MJPs based on uniformized representations of the underlying non-stationary jump processes. This leads to multiple novel MCMC samplers which enable exact (in the Monte Carlo sense) inference tasks for model parameters. We show that proposed samplers outperform existing popular approaches, and offer substantial efficiency gains in applications to partially observed stochastic epidemics, immigration processes and predator-prey dynamical systems.
A protocol to formalise function verbs to support conservation-based model checking

This paper proposes, demonstrates, and validates a protocol to formalise mechanical function verb definitions to support automated analysis of early design concepts, specifically, physics-based model checking using the conservation laws. Present graph-based function structures rely on controlled vocabularies of verbs and nouns to model functions and flows. Currently, all vocabularies define these terms in plain text, allowing inconsistent interpretation and term usage in models, thus making the models unsuitable for formal computational reasoning. To address this limitation, two types of model-level consistencies – topological and conservational – are identified through model examination as critical requirements for physics-based reasoning. A protocol is then demonstrated to evolve three verbs – Branch, Distribute, and Convert_Energy – from their textual definitions into formal classes that include the necessary information elements to support this reasoning. These verbs are used to construct function models, which are then used to simulate reasoning by computer algorithms, thus validating that the definitions indeed support conservation-based model checks at the conceptual level.
Optimization of the Localization Performance of Irregular Ambisonic Decoders for Multiple Off-Center Listeners

This paper presents a method for optimising the performance of irregular Ambisonic decoders for multiple offcentre listeners. New off-centre evaluation criteria are added to a multi objective fitness function, based on auditory localization theory, which guides a heuristic search algorithm to derive decoder parameter sets for the ITU 5-speaker layout. The new evaluation criteria are based upon Gerzon’s Metatheory of Auditory Localisation and have been modified to take into account off-centre listening positions. The derived decoders exhibit improved theoretical localisation performance for off-centre listeners. The theoretical results are supported by initial listening test results.
Optimization methods for phase retrieval from multiple images

The retrieval of phase information from only the magnitude of the Fourier transform of a signal remains an important problem for many applications. We present an algorithm for phase retrieval when there exist two related sets of Fourier transform magnitude data. The data is assumed to come from a single object, observed in two different polarizations through a distorting media, so that the phase component of the Fourier transform of the object is corrupted. The phase retrieval is by minimization of a suitable criterion function, which can take three different forms. Phase retrieval problems associated with SAR imaging are considered.
