Performance Evaluation of Video Streaming in an Infrastructure Mesh Based Vehicle Network

Most next-generation wireless networks are expected to support video streaming which constitutes the bulk of traffic on the Internet. This thesis evaluates the performance of video streaming in a vehicle network with an infrastructure wireless mesh network (WMN) backhaul. Several studies have investigated video quality performance primarily in single hop wireless networks and static WMNs. This thesis is based on those studies and conducts the study in relation to a network where the multi-hop features of the mesh network and mobility of the streaming clients may have substantial impact on the perceived video quality in the network. The study assumes a previously proposed vehicle network architecture consisting of an infrastructure WMN that serves as the mesh backhaul [2, 3]. A number of mesh routers (MRs) form the mesh backhaul using one of their two IEEE 802.11g radios whereas the other radio is used to communicate with the fast moving mesh clients (MCs). Selective MRs called mesh gateways (MGs) are connected to a wired network (e.g., the Internet, hereafter referred to as the core network) via a point-topoint link and provide gateway connectivity to the rest of the network. A server on the core network acts as a video server and streams individual video streams to the fast moving MCs. Upon deployment, network discovery occurs and segregates the network into a number of separate routing zones with each routing zone consisting of a single MG and all the MRs that use the MG as their gateway.

EXTRACTING AND ANALYZING SENTIMENTS OF THE CROWD USING NAÏVE BAYES CLASSIFICATION

In this paper we design and develop restaurant review summarization using Naive bayes Classification with tf-idf. The restaurant review information is based on the sentiment classification result. The condensed description of restaurant reviews are generated from the feature based summarization. We propose a novel approach based on TF-IDF to identify the product features. By using Bayes classifier the main texts in the review are classified into two categories at the sentence level: positive review and Negative review. We consider sentiment classification accuracy to evaluate the system. The rating and review summarization system can be extended to other product review domains easily.
High-precision dating of volcanic events (A.D. 1301-1995) using ice cores from Law Dome,

A record of volcanic activity over the period A.D. 1301–1995 has been extracted from three Law Dome ice cores (East Antarctica). The record dating is unambiguous at the annual level from A.D. 1807 to 1995 and has an uncertainty of ±1 year at A.D. 1301. Signals from 20 eruptions are preserved in the record, including those of two unknown eruptions with acid deposition beginning in A.D. 1810.8 and A.D. 1685.8. The beginning of the ice core signal from the A.D. 1815 Tambora eruption is observed in the austral summer of A.D. 1816/1817. The mean observed stratospheric transport and deposition time to Law Dome from the eruption site is 1.5 years (σ = 0.6 years) from 11 well-dated eruptions. The largest eruption observed in the Law Dome record has its maximum in A.D. 1460 with volcanic sulfate deposition beginning in the austral winter of A.D. 1459. This event is also observed in other ice core records and is attributed to the volcano Kuwae, with an eruption date in the range A.D. 1455.9–1459.9 if all sources of error are considered. This is at least three years later than the date previously ascribed by dendrochronological and historical studies.
CERTAIN MODIFIABLE RISK FACTORS IN ESSENTIAL HYPERTENSION: A CASE- CONTROL STUDY

Essential hypertension accounts for 90% of all cases of hypertension. Though it is a one of major risk factors for cardiovascular diseases, it is a condition with its own risk factors. Overall prevalence of hypertension is increasing over the years in India (from 3.57% in 1977 to 20-30% after 1995). Considering the public health importance of ‘Essential Hypertension’ the present study was conducted. The objective was to study role of certain risk factors in essential hypertension. A case control study was conducted in rural township of Tasgaon; in Sangli district of Maharashtra during 2001-2002, to study role of certain modifiable risk factors in essential hypertension in 21-60 years age group. 165 cases of essential hypertension were selected by systematic random sampling from two private hospitals & O.P.D. of RHTC, Tasgaon and 330, age & sex matched controls were selected in the ratio of 1:2. A significant association was found between essential hypertension and various risk factors including smoking, its frequency and duration, alcoholic status, leisure time physical inactivity, restless sleep, BMI, mental stress, mixed diet and salt intake. Smoking of more than 10 cigarettes or bidi had 3.23 times risk of developing hypertension than smoking up to 10 cigarettes or bidi.
Public Participation as Public Debate: A Deliberative Turn in Natural Resource Management

ABSTRACT This article examines some key similarities and differences between two leading perspectives on public participation: the natural resource management literature and deliberative democratic theory. We assert that contemporary deliberative democratic theory, as proposed by Habermas and others, provides important theoretical and applied insights that are often unexamined in the natural resource literature. Specifically, deliberative democratic theory maintains a focus on the value of public deliberation (dialogue and debate), attention to internal as well as external forms of exclusion, and constructive forms of distrust. The article demonstrates that a deliberative democratic perspective on public participation may serve to challenge some established traditions within the natural resource literature and lead to new ways of conducting and evaluating public participation.
A Corpus Investigation on the Journal of Social Sciences of the Turkic World

In recent years, a rapid development in computer technologies has been witnessed and feasibility of data access has been increased. In today's world, restoring documents, or data in general, and transferring them to interested parties are ordinary tasks. The amount of restored documents has also increased expeditiously and this development has required new technologies to emerge for building knowledge from large data sets. Basic applications of text mining include gathering and processing text to extract information that embodies raw data. Thus, basic text mining applications can help researchers to reach valuable knowledge from a mass of documents. This study investigated academic articles published in bilig (Journal of Social Sciences of the Turkic World) between 1996 and 2017 to find the frequencies of words and letters used in academic Turkish. Basic text mining of 4850817 words in 19437 pages from 81 bilig issues was completed using a natural language processing library, Zemberek and a programming language, R.
A 30‐Minute Physical Education Program Improves Students' Executive Attention

Physical activity is not only beneficial to physical health but also to cognitive functions. In particular, executive functions that are closely related to learning achievement can be improved by acute and recurring physical activity. We examined the effects of a single 30-min physical education program in contrast to a 5-min movement break on working memory, cognitive flexibility, and inhibition of attention and behavioral tendencies of eighty-one 13- to 14-year-old students in grade 7 in Germany. Results indicate that the maintenance of on-task attention in the face of distraction was improved by an aerobic endurance exercise-based physical education program but not by a short aerobic movement break. This suggests that the duration of a school sports program is decisive for improving students' executive attention.
The Effect of Thematic versus Semantic Clustering of English Vocabulary

The present study investigated the effect of thematic vs. semantic clusters of English vocabulary on L2 vocabulary learning. Participants included 60 EFL intermediate learners. During six treatment sessions, forty vocabularies were presented. In thematically clustered group, concept mapping were utilized for word instruction (experimental 1, n=20). In semantic clustering group (experimental 2, n=20) synonym of the words were presented. The comparison group (n=20) received placebo. Following the treatment all participants took immediate and delayed posttests. Results of split–plot and two Tukey post hoc ANOVAs revealed that although both thematic and semantic clustering improved learners’ vocabulary knowledge, the thematic clustering group was much more superior in vocabulary learning and retention. Semantic clustering group performed better than comparison group in immediate posttest but not on delayed posttest and consequently had less impact on retention.
Motivation and learning impact of Dutch flu-trackers

Many citizen science projects deal with high attrition rates. The Dutch Great Influenza Survey is an exception to this rule. In the current study, we conducted an online questionnaire (N=1610) to investigate the motivation and learning impact of this loyal, active participant base. Results show that the desire to contribute to a larger (scientific) goal is the most important motivator for all types of participants and that availability of scientific information and data are important for learning. We suggest similar projects seek (social) media attention regularly, linking project findings to current events and including the importance of participants’ contribution. Abstract
Community Health Centres: An Innovative Approachto Newcomer Settlement Services

While NGO settlement agencies face increasing challenges to deliver bath ethnospecific and larger broad-based programs for immigrants and refugees, Community Health Centres (CHCs) in large urban areas of Ontario have developed innovative means to meet the health and settlement needs of newcomers. Positive mental and physical health through access to medical and social resources, recognition of health determinants and enhanced participation in decision making are integral elements of CHC settlement and integration programs and services, all within the context of medical care. Through extensive outreach programs to newcomer communities, CHCs enhance the efectiveness of ethnospecific groups to define culturally appropriate services. CHCs provide an example of desired social change through a mainstream institutional basis.
Ethnic Differences in Susceptibility to Smoking and Intention to Smoke on Smoking Behavior among Adolescents

Objectives: This quantitative study examined the differences in susceptibility to smoking and intention to smoke on smoking behavior among adolescents of different ethnic groups. Methods: The study utilized secondary data from the 2007 National Survey on Drug Use and Health (NSDUH). The study population included 18,314 persons in the ages 12-17 years, both smokers and nonsmokers and representing the races: White, African American, Hispanic, Asian, Multi-Racial, American Indian and Native Hawaiian. The theory of reasoned action by Ajzen and Fishbein formed the basis of this study. Results: A statistically significant positive relationship was found between participants’ susceptibility to smoking and their intentions to smoke (r = .57, p < .01). Additionally, Hispanics demonstrated a significantly higher intention to smoke in the next 12 months than the White participants. More specifically, a significant difference was found among ethnic groups on smoking intentions and among age groups on susceptibility to smoking. Discussion: The constructs of susceptibility to smoking and intention to smoke can be targeted by health education interventions in primary and secondary interventions to reduce smoking behavior in different ethnic groups.
The Impact of Study Quality on the Image of a Higher Education Institution

Issues concerning the image and reputation strengthening of higher education institutions have recently been given an important consideration in Lithuania and other European countries. In the article we will discuss the fundamentals of the university education quality and image strengthening in theoretical premises, and illustrate them using data of studies performed at the Vilnius University. The research results demonstrate that the quality of studies is the main factor in determining the image of a higher education institution.

IMAGING BIREFRINGENT MINERALS WITHOUT EXTINCTION USING CIRCULARLY POLARIZED LIGHT

Linear cross-polarized optical images reveal the birefringence of mineral grains and are very useful in petrography. However, if the vibration directions of the crystal are not at 45° to the polarizers, then the intensity of the interference colors is reduced, and in some orientations, to zero (extinction). This reduction in intensity, and extinction, can be eliminated if circular polarizers are used in place of linear polarizers. The interference colors of colorless minerals then correspond exactly with those on the Michel-Levy chart. Similarly, isogyres are eliminated from conoscopic images. This simple, inexpensive technique can be used with ordinary petrographic microscopes and scanners. It can be very useful for quantification of textures (microstructures) from single images.
Atlantic Meridional Overturning Circulation (AMOC) in CMIP5 Models: RCP and Historical Simulations

AbstractThe Atlantic meridional overturning circulation (AMOC) simulated by 10 models from phase 5 of the Coupled Model Intercomparison Project (CMIP5) for the historical (1850–2005) and future climate is examined. The historical simulations of the AMOC mean state are more closely matched to observations than those of phase 3 of the Coupled Model Intercomparison Project (CMIP3). Similarly to CMIP3, all models predict a weakening of the AMOC in the twenty-first century, though the degree of weakening varies considerably among the models. Under the representative concentration pathway 4.5 (RCP4.5) scenario, the weakening by year 2100 is 5%–40% of the individual model's historical mean state; under RCP8.5, the weakening increases to 15%–60% over the same period. RCP4.5 leads to the stabilization of the AMOC in the second half of the twenty-first century and a slower (then weakening rate) but steady recovery thereafter, while RCP8.5 gives rise to a continuous weakening of the AMOC throughout the twenty-first .
Buckling Analysis of Carbon Nanotube Reinforced Polymer Composite Plates

Buckling behavior is an important consideration in the design of structural components. In the present investigation, a study of multi-scale analysis of the buckling of a Carbon Nanotube (CNT) reinforced polymer composite plate is presented. A micromechanics model based on the Mori-Tanaka method is developed by introducing straight CNTs aligned in one direction. An attempt is made to find the buckling behavior using classical plate theory. The effect of plate aspect ratio is investigated on the plate buckling. The study is conducted primarily with an intention of observing the effect of CNTs when used in structural applications such as plates.
Generalized proportional con ict redistribution rule applied to Sonar imagery and Radar targets classi cation

In this chapter, we present two applications in information fusion in order to evaluate the generalized proportional con ict redistribution rule presented in the chapter [5]. Most of the time the combination rules are evaluated only on simple examples. We study here di erent combination rules and compare them in terms of decision on real data. Indeed, in real applications, we need a reliable decision and it is the nal results that matter. Two applications are presented here: a fusion of human experts opinions on the kind of underwater sediments depict on sonar image and a classi er fusion for radar targets recognition.
Variability of carbon monoxide and carbon dioxide apparent quantum yield spectra in three coastal estuaries of the South Atlantic Bight

Abstract. The photochemical oxidation of oceanic dissolved organic carbon (DOC) to carbon monoxide (CO) and carbon dioxide (CO2) has been estimated to be a significant process with global photoproduction transforming petagrams of DOC to inorganic carbon annually. To further quantify the importance of these two photoproducts in coastal DOC cycling, 38 paired apparent quantum yield (AQY) spectra for CO and CO2 were determined at three locations along the coast of Georgia, USA over the course of one year. The AQY spectra for CO2 were considerably more varied than CO. CO AQY spectra exhibited a seasonal shift in spectrally integrated (260 nm–490 nm) AQY from higher efficiencies in the autumn to less efficient photoproduction in the summer. While full-spectrum photoproduction rates for both products showed positive correlation with pre-irradiation UV-B sample absorption (i.e. chromophoric dissolved organic matter, CDOM) as expected, we found no correlation between AQY and CDOM for either product at any site. Molecular size, approximated with pre-irradiation spectral slope coefficients, and aromatic content, approximated by the specific ultraviolet absorption of the pre-irradiated samples, were also not correlated with AQY in either data set. The ratios of CO2 to CO photoproduction determined using both an AQY model and direct production comparisons were 23.2 ± 12.5 and 22.5 ± 9.0, respectively. Combined, both products represent a loss of 2.9 to 3.2% of the DOC delivered to the estuaries and inner shelf of the South Atlantic Bight yearly, and 6.4 to 7.3% of the total annual degassing of CO2 to the atmosphere. This result suggests that direct photochemical production of CO and CO2 is a small, yet significant contributor to both DOC cycling and CO2 gas exchange in this coastal system.
Analysis of Sensing Mechanisms in a Gold-Decorated SWNT Network DNA Biosensor

We show that carbon nanotube sensors with gold particles on the single-walled carbon nanotube (SWNT) network operate as Schottky barrier transistors, in which transistor action occurs primarily by varying the resistance of Au-SWNT junction rather than the channel conductance modulation. Transistor characteristics are calculated for the statistically simplified geometries, and the sensing mechanisms are analyzed by comparing the simulation results of the MOSFET model and Schottky junction model with the experimental data. We demonstrated that the semiconductor MOSFET effect cannot explain the experimental phenomena such as the very low limit of detection (LOD) and the logarithmic dependence of sensitivity to the DNA concentration. By building an asymmetric oncentricelectrode model which consists of serially-connected segments of CNTFETs and Schottky diodes, we found that for a proper explanation of the experimental data, the work function shifts should be ~ 0.1 eV for 100 pM DNA concentration and ~ 0.4 eV for 100 μM.
The role of host plant resistance in the colonization behavior and ecology of bark beetles (Coleoptera: Scolytidae)

Unlike most phytophagous insects, the reproduction of primary bark beetles (Coleop- tera: Scolytidae) is contingent on host mortality. Consequently, there have been intense selective pressures on trees for properties which confer resistance to attack, and likewise, on the insect for increased behavioral complexity by which to overcome these defenses. In this study, we examined the relationship between the physiology of Pinus contorta var. latifolia and the behavior of the bark beetle, Dendroctonus ponderosae. Host mortality is a discrete outcome which is contingent on the quantitative interaction between host resistance and beetle numbers. At low attack densities, trees respond by confining beetles and their associated fungi within necrotic lesions containing toxic or inhibitory compounds. Beyond a critical "threshold of attack," however, the defensive capacity of the tree is exhausted, and mortality occurs. This threshold occurred at -40 galleries/m2 in our experimental stands. The reproductive success of the bark beetle is directly related to the depletion of host defenses through concentrated attack. At sufficiently high attack densities, -80 galleries/M2, the potential suppressive effect of the host on brood development is not manifested. Increased beetle numbers, however, cause an exponential decline in brood production due to intraspecific competition. Conse- quently, there is an optimal density, =62 attacks/M2 at which reproduction and survival of the beetle is maximized. Dendroctonus ponderosae utilize defensive secretions as precursors and synergists of aggregation pheromones, and thereby, elicit maximum responses from flying beetles while the host's production of toxins is at its maximum. This mechanism also ensures that the attack will terminate once the tree has been rendered suitable for brood development and, thus, minimizes the deleterious effect of intraspecific competition. Such an interaction, in which all trees could theoretically be colonized regardless of their resistance capacity, cannot result in a stable host-parasite system. Conifers, however, seem to be able to interfere with bark beetle communication. Pheromone synthesis within the hindgut and emission from the entrance site are distinct events, and beetles contained within a copious flow of resin seem unable to elicit attraction. This ability to interrupt the beetles' communication sequence, however, is in- versely related to the number of beetles initiating localized attacks. Consequently, the colonization sequence reflects the outcome of a dynamic interaction between the tree and the initial "pioneer" beetles.
