Sensor Interaction as a Source of the Electromagnetic Field Measurement Error

Abstract The article deals with analytical calculation and numerical simulation of interactive influence of electromagnetic sensors. Sensors are components of field probe, whereby their interactive influence causes the measuring error. Electromagnetic field probe contains three mutually perpendicular spaced sensors in order to measure the vector of electrical field. Error of sensors is enumerated with dependence on interactive position of sensors. Based on that, proposed were recommendations for electromagnetic field probe construction to minimize the sensor interaction and measuring error.
Urbanizing Watersheds and Changing River Flood Dynamics: Implications for Urban Wetland Restoration

Urbanization alters river hydrology, morphology, water quality, and habitat and ecology. Most of these associated changes are due to an increase in impervious surface cover (ISC) throughout the watershed. But the spatial location of urban areas within the watershed also greatly influences river hydrology. As river hydrology changes, functions and structure of riverine wetlands associated with the hydrology may be impacted. In order to increase the longterm success of wetland restoration attempts within an urbanizing environment, it is necessary to quantify potential impacts to the wetlands as hydrology continues to change. This study investigated the effects of increased ISC on stream hydrology between 1972 and 1995 for a subwatershed located north of Dallas, Texas. Moving window and FRAGSTATS analyses calculated the degree and location of ISC throughout the basin, and U.S. Geologic Survey stream-gauge data were analyzed to determine changes in steam hydrology between the 2 time periods. Average ISC for the watershed increased from 2 to 11% between 1972 and 1995, but highest cover (50–80%) occurred along the southern and eastern borders. Annual river flooding frequency and duration doubled between 1972 and 1995, and flooding velocity increased from 31.4 to 35.4 m3/sec. Wetland restoration attempts within the watershed should address the potential for future hydrologic changes as ISC continues to increase.
A systematic social observation tool to measure the restorative potential of urban settings / Diseño de una herramienta de observación social sistemática del potencial restaurador de espacios urbanos

Abstract The study of psychological restoration in urban settings has undergone significant growth in recent years. The aim of this paper is to develop an instrument for the objective evaluation of the restorative potential of urban public spaces. Perceived restoration scales and a large number of systematic social observation instruments were reviewed, selecting items that might be suitable for the aims of this study and adding other items designed ad hoc. The resulting tool is made up of 183 items, grouped into 12 domains. The final format of the instrument was used by a group of four evaluators in a total of six urban squares. This paper reports the statistics obtained for the internal consistency of the instrument (inter-judge agreement) and convergent validity through correlations of the objective scores from each public square with the perceived and experienced restoration of a sample of users of said public squares (N = 296). The tool delivered an adequate level of reliability, and its scores were related to restoration measures, although the size of this association was small.
Volatile organic compounds in the western Mediterranean basin: urban and rural winter measurements during the DAURE campaign

Abstract. Atmospheric volatile organic compounds (VOCs) have key environmental and biological roles, but little is known about the daily VOC mixing ratios in Mediterranean urban and natural environments. We measured VOC mixing ratios concurrently at an urban and a rural site during the winter DAURE campaign in the northeastern Iberian Peninsula, by means of PTR-MS at both locations: a PTR-Quad-MS at the urban site and a PTR-ToF-MS at the rural site. All VOC mixing ratios measured were higher at the urban site (e.g. acetaldehyde, isoprene, benzene, and toluene with averages up to 1.68, 0.31, 0.58 and 2.71 ppbv, respectively), with the exception of some short-chain oxygenated VOCs such as acetone (with similar averages of 0.7–1.6 ppbv at both sites). The average diurnal pattern also differed between the sites. Most of the VOCs at the urban location showed their highest mixing ratios in the morning and evening. These peaks coincided with traffic during rush hour, the main origin of most of the VOCs analyzed. Between these two peaks, the sea breeze transported the urban air inland, thus helping to lower the VOC loading at the urban site. At the rural site, most of the measured VOCs were advected by the midday sea breeze, yielding the highest daily VOC mixing ratios (e.g. acetaldehyde, isoprene, benzene, and toluene with averages up to 0.65, 0.07, 0.19, and 0.41 ppbv, respectively). Only biogenic monoterpenes showed a clear local origin at this site. In addition, the concentrations of fine particulate matter observed at both sites, together with the synoptic meteorological conditions and radio-sounding data, allowed the identification of different atmospheric scenarios that had a clear influence on the measured VOC mixing ratios. These results highlight the differences and relationships in VOC mixing ratios between nearby urban and rural areas in Mediterranean regions. Further research in other urban-rural areas is warranted to better understand the urban-rural influence on atmospheric VOC mixing ratios under different atmospheric conditions.
Utilizing Mine Tailings as Substitute Construction Material: The Use of Waste Materials in Roller Compacted Concrete

Mine tailings (MT) have been used in previous studies as substitute construction material to recycle waste products, especially in hollow blocks and bricks production and as masonry mortar. This study investigated the use of Philex copper-gold mine tailings (PCGMT) in roller compacted concrete (RCC) production, a mining waste material consisting of finely grinded siliceous particles was obtained from Tailings Pond number 2 (TP2) of a Philippine copper and gold mining company. A comprehensive experimental program was conducted to investigate the comparative compressive strength of RCC containing Porac sand (RCCPS) and RCC with copper-gold mine tailings (RCCCGMT), and the durability of RCC with copper-gold mine tailings and fly-ash (RCCCGMTFA). Varying mixtures of RCCPS and RCCCGMT with very low, low, medium, and high cement contents were casted and tested. The compressive strength attained at 28 days by RCCPS and RCCCGMT ranges from 17 to 37 Mega Pascal (MPa) and 17 to 28 Mpa, respectively. The obtained values indicate that the latter requires greater amount of cement and the mixtures with compressive strength values greater than 25 Mpa are acceptable for concrete pavement use. The durability of RCCCGMTFA with medium cement content was evaluated by subjecting the specimens to an alternate wetting and drying cycles. After 15 cycles, a remaining strength of 18.7 MPa was obtained which indicated that it could endure stresses due to weather changes in the Philippines. Results show that PCGMT in TP2 are viable sand or fine aggregates substitute in RCC.
The Impact of Subregional Integration on Bilateral Trade: The Case of UEMOA

The aim of this study was to evaluate the impact of preferential trade agreements and the monetary union on bilateral trade between UEMOA member countries. With the use of a dynamic gravity model, it was possible to realize that membership in a common monetary zone and the implementation of common economic reforms had a significant effect on bilateral trade within the zone, although more in terms of diverting imports and exports than in terms of creating trade. Furthermore, economic policy distortions that foster informal transborder trade had a negative effect on trade within the region.
A Security Audit Module for HBase

NoSQL databases provide us with highly available and highly scalable data storage solutions. During the operation on huge amounts of data, security issues have become more and more important. Security audit is an important feature for NoSQL database security. An audit module will monitor and record users’ accessing activity on the database. Thus we can identify risks such as illegal operations, right violation, etc. We designed a security audit module to enhance security for HBase. We get accessing information by defining hook function in coprocessor. Then we implement a flexible set of rules to filter logs. The evaluation shows that the system can record required accessing information thus improves security of HBase.
Deer overbrowsing on autumn‐flowering plants causes bumblebee decline and impairs pollination service

Increased ungulate browsing has altered the composition of plant communities and food webs of forest ecosystems in many regions around the world. To evaluate the cascading impact of deer browsing on pollination and plant reproduction is critical to understand the roles of species interactions in maintaining plant populations and for conservation management. In this study, we investigated the relationships among floral resources of understory herbaceous plants, pollinator visitation, and fruit set of shrub species based on data accumulation over three years in six temperate deciduous forests with deer and without deer. We found that in deer browsed sites, the visitation rate of bumblebees had decreased due to severe reduction in the coverage of autumn-flowering herbaceous plants, while the effect varied between bumblebee species. On the other hand, other insect taxa showed no dependence on variation in autumn floral resources. The two genera of bumblebee-pollinated shrubs showed reduced fruit set due to se.
A Reliable, Non-Invasive Approach to Data Center Monitoring and Management

Recent standards, legislation, and best practices point to data center infrastructure management systems to control and monitor data center performance. This work presents an innovative approach to address some of the challenges that currently hinder data center management. It explains how monitoring and management systems should be envisioned and implemented. Key parameters associated with data center infrastructure and information technology equipment can be monitored in real-time across an entire facility using low-cost, low-power wireless sensors. Given the data centers’ mission critical nature, the system must be reliable and deployable through a non-invasive process. The need for the monitoring system is also presented through a feedback control systems perspective, which allows higher levels of automation. The data center monitoring and management system enables data gathering, analysis, and decision-making to improve performance, and to enhance asset utilization.
Physical activity and child health : Can school-based interventions make a difference ?

Childhood obesity and inactivity is a significant public health problem that also has economic consequences. Therefore, economists have a role to play in identifying their potential impact. The influence of childhood background on outcomes can usefully be divided according to the effects of family, school and peers. Schools have been promoted as a potential arena to combat the increasing childhood obesity rate. This study analyses whether increasing physical activity in the school context can contribute to health improvement exploring four different types of interventions. We address the issue using a unique longitudinal data set of 1087 (BMI) and 1047 (fitness) schoolchildren who attend 37 state schools in the Municipality of Aalborg, Denmark. The effect is identified using a randomised experiment that creates an exogenous increase in physical activity. Surprisingly, we find that the interventions did not have the expected impact on schoolchildren’s health, and the scant evidence we have points towards a negative effect. We pay particular attention to possible explanations for this lack of results. Our analysis suggests that the interventions had a heterogeneous impact on children’s health when only parts of the distribution are considered. Even more convincing are the results, which indicate that schoolchildren engage in compensating behaviour implying a crowding-out of leisure-time activity. Consequently, a supportive cost-benefit case might exist if parental behaviour is assumed to be affected by school-based interventions. JEL codes: I14, I12, C18
Toxicity of botanic and synthetic pesticide residues to citrus psyllid Diaphorina citri Kuwayama and Chrysoperla carnea (Stephens).

Bioassays were conducted to investigate the toxicity and residual activity of botanic and synthetic pesticides against adult female citrus psyllids, Diaphorina citri Kuwayama and second instar larvae of Chrysoperla carnea (Stephens). A dose of 1% neem seed oil inflicted 80% mortality on D. citri and 100% to C. carnea within 48 hours. Neem seed extract at a high dose of 3% resulted in 68.0 and 80% mortality to D. citri and C. carnea, respectively. Addition of 5% sugar to neem oil or neem water extract as feeding stimulant improved toxicity of the product to about 30 and 50%, respectively. Bioassays with synthetic pesticide such as methomyl and imadicloprid inflicted 97-100% mortality to D. citri on day 4, 70% and 34% on day 9 post application. Decline in mortality was gradual in case of methomyl but very quick in imidacloprid and lambda cyhalothrin from 100% on day 1 to 60% and 35% on day 9, respectively. Neem oil and its extract also degraded very quickly and showed decline in mortality from 80 to 20% within 5 days post application period.
Kinematical Brownian Motion of the Harmonic Oscillator in Non-Commutative Space

In this work the Jacobi’s second equality in the form of stochastic equation and the Wiener path integral approach are used to evaluate the probability density of harmonic oscillator in non-commutative space. Using the factorization theorem and the Mastubara formalism, the thermodynamic parameters are determined. The structure of Fokker-Planck equation remained the same even in a commutative and non-commutative space. Moreover, the non-commutative parameter is depicted for increasing value of the entropy.

Review of the most important pathogens in Serbian forest nurseries

Successful reforestation depends on the quality and health of seedlings. Targeted production in forest nurseries should produce plants that will be able to survive unfavorable environmental and weather conditions in Serbia. Pathogens can reduce the vitality of seedlings and decrease survival after outplanting. The most common pathogens identified on seeds of both conifer and broadleaved seedlings are presented. The most frequently used fungicides for the control of pathogens in Serbian forest nurseries, as well as the best time of their application, are reviewed.
EXAMINING ADULT'S IDENTITY STATUSES: ADAPTIVE VS. MALADAPTIVE DIMENSION

To achieve the status of ego identity remains the most important challenge for the adolescence period and consequently is a challenge for developmental psychologists too. The vast majority of studies focus on understanding the dynamics of ego identity development, however, factors that cause different path of development remained unclear. This study aims at tracking the paths, which differentiate ego statuses from finding psychosocial factors contributing to ego identity achievement. For this purpose the relationships between four identity statuses - achievement, exploration, moratorium and foreclosure and number of psychosocial variables such as attachment style, self-esteem and perfectionism have been examined. 386 school teenagers aged 14-17 (M = 15.48) filled a set of questionnaires comprised of four instruments: The Ego Identity Process Questionnaire (EIPQ), The Measure of Attachment Qualities (MAQ), The Perfectionism Inventory (PI) and Adult Sources of Self-Esteem Inventory (ASSEI). Discriminant analysis revealed two basic dimensions (adaptive and maladaptive), which are capable to depict the difference between ego identity statuses. The first discriminant function of ego identity status is primarily defined by conscientious perfectionism and secured attachment; whereas, the second discriminant function consists of avoidance attachment, self-evaluative perfectionism and ambivalent attachment styles.
Is China a single united market for foreign investors ? – Federalism , Chinese style and inward foreign direct investment in China

Whilst existing research on the locational determinants of inward foreign direct investment (FDI) in China and Federalism, Chinese style makes important contributions to the literature in its own right, there has been a lack of formal econometric work in the literature to systematically quantify the relationship between Federalism, Chinese style and location choice of foreign investors in China. This study develops a spatial dynamic model that explicitly addresses spatial externalities and path-dependent effects of inward FDI and host location attractiveness, in examining the spatial distribution of inward FDI in China under Federalism, Chinese style. An empirical application of this model to a dataset of inward FDI across Chinese provinces over 1997-2012 shows that the location of FDI in China is determined by a combination of negative spatial externalities and positive path-dependent effects of FDI, and different host regional characteristics. This result implies that the Chinese market is highly fragmented for foreign investors.
UNIVERSITÉ DU QUÉBEC À MONTRÉAL NUMERICAL MODELLING OF LATERAL VISCOSITY VARIATIONS IN THE EARTH' S MANTLE THESIS SUBMITTED AS A PARTIAL REQUIREMENT FOR THE DEGREE OF MASTER OF SCIENCE IN EARTH SCIENCES BY MARIE NICOLE THOMAS

The open-source code ASPECT is used to model the impact of lateral viscosity variations on instantaneous mantle flow and dynamic topography. The initial viscosity follows the geodynamically inferred 'V2' profile of Mitrovica and Forte (2004) which varies with depth alone. The lateral component of the viscosity is computed assuming an Arrhenius-type temperature dependence, with the perturbed temperature field given by the seismic tomography mode! GyPSuM, which unique! y incorporates data from geodynamic observations and mjneral physics experiments (Simmons et al., 2010). Comparisons between GyPSuM and the S40RTS seismic tomography mode! of Ritsema et al. (20 Il) confirms earlier findings that shear-wave velocities alone are not sufficient to characterise the complex, three-dimensional heterogeneities of the Earth' s mantle. In general, lateral viscosity variations are found to increase the vigour of mantle flow and to moderate the amplitude of dynamic topography. Different amplitudes are also investigated, but the ASPECT numerical sol ver demonstrates convergence problems beyond modest lateral viscosity contrasts. Possible solutions and directions for future work are discussed .
The impact of online lecture recordings on student performance

The use of online lecture recordings as a supplement to physical lectures is an increasingly popular tool at many universities. As its popularity grows, however, there is increasing evidence that some students are using these recordings as a substitute to attending the actual lectures, rather than as a complement that helps them revisit difficult content, or for study purposes. Does this trend matter? If students receive as much (if not more) benefit from viewing their lectures online as they do by attending in person, then this is surely the student’s right. However, this has potentially significant consequences for the delivery of lecture content in higher education. This paper combines survey data with student record data for students in a first year Microeconomics class to examine this issue. The main finding is that, whilst there are indeed some students using online lecture recordings as a substitute to attending lectures, they are ultimately at a fairly severe disadvantage in terms of their final marks. Controlling for a wide variety of student characteristics, we find that, relative to attending zero to six lectures (out of 26), those attending essentially all lectures in person (25 or 26 lectures) have a direct advantage of nearly eight marks. Moreover, students attending zero to six lectures do not close this gap by viewing more lectures online, despite having double the number of lecture recording hits as their colleagues who attended 25-26 lectures. In contrast to this, students who attend the majority of lectures in person do receive a benefit from additional use of the lecture recordings. The results provide evidence that, when used as a complementary tool, lecture recordings are a valuable supplement for students. However, when used as a substitute, lecture recordings provide no additional benefit.
Learning a Second Language Naturally the Voice Movement Icon Approach

Second language (L2) instruction greatly differs from natural input during native language (L1) acquisition. Whereas a child collects sensorimotor experience while learning novel words, L2 employs primarily reading, writing and listening and comprehension. We describe an alternative proposal that integrates the body into the learning process: the Voice Movement Icon (VMI) approach. A VMI consists of a word that is read and spoken in L2 and synchronously paired with an action or a gesture. A VMI is first performed by the language trainer and then imitated by the learners. Behavioral experiments demonstrate that words encoded through VMIs are easier to memorize than audio-visually encoded words and that they are better retained over time. The reasons why gestures promote language learning are manifold. First, we focus on language as an embodied phenomenon of cognition. Then we review evidence that gestures scaffold the acquisition of L1. Because VMIs reconnect language learning with the body, they can be considered as a more natural tool for language instruction than audio-visual activities.
Discrete Morse theory and Hopf bundles

We use Hopf bundles to give an example of a regular CW complex X and an acyclic matching M on the face poset of X, such that there are no critical cells in neighboring dimensions but the complex X is not homotopy equivalent to the corresponding wedge of spheres. The key fact here is that the higher homotopy groups of spheres are nontrivial. We also give a sufficient condition on an acyclic matching M for concluding that X is homotopy equivalent to a wedge of spheres indexed by the critical cells.
