Near- and far-field plume studies of a one-kilowatt arcjet

To support studies of transport in arcjet plumes, axial and radial profiles of electron temperature, electron number density, stagnation pressure, and flow field were obtained over an extensive volume of the plume of a 1-kW arcjet operating on hydrogen. All experiments were performed in a 6 by 9 m vacuum chamber at a tank pressure of less than 4 x 10 ~4 torr during arcjet operation. Electron temperatures obtained spectroscopically 1.2 cm downstream of the exit plane ranged from 0.10 to 0.13 eV, while electron number densities determined ~2 cm downstream of the exit plane via langmuir probe varied between 0.3-1 x 10 12 cm~3. Far-field langmuir probe measurements showed that a rapid radial variation in electron number density exists, ranging from 0.5 to 5 x 10 9cm~3, and from 0.5 to 2 x 10 9 cm~3, 30 and 88 cm downstream of the exit plane, respectively. Electron temperatures at these axial locations show much less of an axial dependence, ranging between 0.070. 20 eV at both axial positions. Finally, an impact pressure probe was used to measure the radial profiles of stagnation pressure 53 and 64 cm from the exit plane as well as flow angle. The impact pressure probe data compare favorably with stagnation pressures predicted by a source-flow code and suggests that the heavy particles diffuse less radially than do the electrons.
Object Feature Extraction of Songket Image Using Chain Code Algorithm

The study was aimed at determining the feature of a motif found in a Songket image in order to make the object detectable and readable. The method used was image color segmentation in the form of a process of segmentation of the image area based on the similarity in colors, which was continued with the binary process that aims to change the image into binary form (0 and 1), so that it only has two colors namely black and white. This study also used mathematical morphology in detecting objects, by using dilation operation and filling holes. After the process of mathematical morphology was completed, the next process was motif extraction by applying moore contour tracking algorithms and the development of chain code algorithms. The results of the process carried out showed that the development chain code algorithm can generate the number of objects, the length of chain code, and probable value of rate of appearances of each chain code in a motif, despite there are some objects in a motif. Then the values are stored into the database as The Feature of Songket Motifs.
Study on Mechanism of Viscoelastic Polymer Transient Flow in Porous Media

Oil recovery, including conventional and viscous oil, can be improved significantly by flooding with polymer solutions. This chemical flooding method can increase oil production, and it can improve the macrodisplacement efficiency and microsweep efficiencies. In this study, we establish physical models that include the dead-end and complex models based on the pore-network pattern etched into glass, using the snappyHexMesh solver in OpenFOAM. These models capture the complexity and topology of porous media geometry. We establish a mathematical model for transient flows of viscoelastic polymers using computational fluid dynamics simulations, and we study the distributions of pressure and velocity for different elasticity scenarios and different flooding process. The results demonstrate that the pressure difference increases as the relaxation time decreases, before the flow reaches its steady state. For a steady flow, elasticity can give rise to an additional pressure difference, which increases with increasing elasticity. Thus, the characteristics of pressure difference vary before and after the flow becomes steady; this phenomenon is very important. Velocity contours become more widely spaced with elasticity increase. This suggests that elasticity of the polymer solutions contributes to the microsweep efficiency. The results of the study provide the necessary theoretical foundation for laboratory experiments and development of methods for polymer flooding and can be helpful for the design and selection of polymers for polymer flooding.
Synthesis and Humidity Sensing Investigations of Nanostructured ZnSnO 3

In this paper zinc stannate (ZnSnO3) nanoparticles was synthesized by a chemical precipitation method. The synthesized samples were characterized using X-ray powder diffraction (XRD), Differential scanning calorimetry (DSC) and UV-Visible absorption spectroscopy. Sensing material was made as pellet by hydraulic press machine under uniform pressure of 616 MPa. Then the material was annealed at 600。 C. Surface morphologies of the samples were analyzed using Scanning electron microscopy (SEM) for pellet of different weight ratio annealed at 600。 C. The XRD pattern indicates that ZnSnO3 has a perovskite phase with an orthorhombic structure having minimum crystallite size 4 nm. Further, humidity sensing investigations of these sensing materials were done. Our result indicate that ZnSnO3 in form of pellet annealed at 600。 C for 1:4 weight ratio was most sensitive of humidity in comparison to pure SnO2 under same conditions. Maximum sensitivity of the sample was 3 GΩ/% RH which is better in comparison to pure SnO2. The results were reproducible up to ± 77% after 2 months of observations.
HYBRID DIFFERENTIAL EVOLUTIONARY SYSTEM FOR TIME SERIES PREDICTION

 This paper presents a Hybrid Differential Evolutionary System (HDES) for time series forecasting. It consists of an intelligent hybrid model composed of an Arti cial Neural Network (ANN) combined with an Improved Differential Evolution (IDE). The IDE searches for the relevant time lags for a correct time series characterization, the number of processing units in the ANN hidden layer, the ANN training algorithm and the modeling of ANN. Initially, the proposed HDES chooses the most tted forecasting model, thus it performs a behavioral statistical test in the attempt to adjust forecast time phase distortions that appear in some time series. An experimental analysis is conducted with the proposed HDES using three real world time series and ve well-known performance measures are used to assess its performance. The obtained results are compared to MultiLayer Perceptron (MLP) networks and the previously introduced Time-delay Added Evolutionary Forecasting (TAEF) method. Keywords Arti cial Neural Networks, Differential Evolution, Hybrid Systems, Time Series Forecasting.
TRANSIENT THERMOELASTIC ANALYSIS FOR A FUNCTIONALLY GRADED CIRCULAR DISK WITH PIECEWISE POWER LAW

The theoretical treatment of a transient thermoelastic problem involving a functionally graded solid circular disk with piecewise power law due to uniform heat supply from an outer surface is studied. The solid circular disk is also cooled from the upper and lower flat surfaces. The functionally graded circular disk consists of many thin circular layers in order to guarantee the voluntariness of material position dependency. The thermal conductivity, Young's modulus and the coefficient of linear thermal expansion of each layer, except the first inner layer, are expressed as power functions of the radial coordinate, and their values continue on the interfaces. We obtain the exact solution for the one-dimensional temperature change in a transient state, and in-plane thermoelastic response under the state of plane stress. Some numerical results for the temperature change, displacement and stress distributions are shown in figures.
Second-order nonlinearity assisted by dual surface plasmon resonance modes in perforated gold film

We have studied analytically the reflection assisted with surface plasmon through the square lattice perforated gold film. Under the excitation of the external electromagnetic field with one or two different frequencies, the second-order nonlinearity exists in this noncentrosymmetric metal-based metamaterial. We employed the two surface plasmon resonances modes with different lattice periods. With the excitation of two different plasmon resonances modes, the strong local field induces an expected increase of the second-order nonlinearity including second harmonic generation as well as the sum (difference) frequency generation. The field distributions results also indicate that the enhancement of sum frequency signals and difference frequency signals strongly depends on surface plasmon resonance effect.
On coverage in infrastructure networks

For mobile distributed tasks, the infrastructure is often formed by cellular networks. One of the major issues in such networks is interference. In this paper we tackle interference reduction by suitable assignment of transmission power levels to base stations. This task is formalized introducing the Minimum Membership Set Cover combinatorial optimization problem. On the one hand we prove that in polynomial time the optimal solution of the problem cannot be approximated more closely than with a factor lnn. On the other hand we present an algorithm exploiting linear programming relaxation techniques which not only asymptotically matches the lower bound with high probability but also performs well in practical networks.
Work Values, Occupational Engagement, and Professional Quality of Life in Counselors-in-Training: Assessments in a Constructivist-Based Career Counseling Course

In this investigation, a sample of counselors-in-training’s (CITs) work values, occupational engagement, and professional quality of life were explored at preand post-completion of a career counseling course. In relation to work values, participants highly valued balance, support, helping, and honesty within their careers, while power, competition, and risk-taking were least valued. Overall, participants increased their levels of occupational engagement from preto post-assessment over the span of the career counseling course. Finally, participants experienced moderate levels of compassion satisfaction and experienced low levels of burnout and compassion fatigue in relation to their professional quality of life. Implications of these findings for counselors, counselor educators, and CITs include: (a) incorporation of constructivist pedagogy; (b) discussion of essential counseling-related factors (e.g., burnout, compassion fatigue, compassion satisfaction); (c) the importance of wellness support; and (d) incorporation of assessments in counseling classrooms.
A Contrast-based Analysis of Consonant Cluster Simplification in English

The purpose of this paper is to reconsider Consonant Cluster Simplification in English. We first provide a brief review of previous syllable-based analyses of the phenomenon, showing that they are empirically inadequate. Then considering CCS within a framework of the cue-based theory (Steriade, 2000), we claim that it can be given a natural and unified account in terms of the perceptual salience of the involved consonants. We claim that the quality and quantity of the internal and external cues determine CCS: Consonants with perceptually salient phonetic cues resist deletion, while consonants lacking salient cues are relatively prone to deletion.
Food habits of harbor seals (Phoca vitulina richardii ) in San Francisco Bay, California

FOOD HABITS OF HARBOR SEALS (PHOCA VITULINA RICHARDII) IN SAN FRANCISCO BAY, CALIFORNIA By Corinne Michele Gibble The diet of harbor seals (Phoca vitulina richardii) in San Francisco Bay (SFB) in California was examined from July 2007 to July 2008 via scat analysis. Scats were collected from five major haul-out sites; 22 species of fish and one species of crustacean were identified from 422 scats. The reliance of a non-native invasive species, Yellowfin Goby (Acanthogobius flavimanus), increased in importance in the diet. Additionally, another non-native invasive fish species, Chameleon Goby (Tridentiger trigonocephalus), was found for the first time in the diet of harbor seals in SFB. Harbor seal diet was compared between seasons, locations, and years using Spearman’s rank correlations; diet was statistically different between years (1991-1992 and 2007-2008), between the pupping and non-pupping seasons, and between North SFB and South SFB haul-out locations. California Department of Fish and Game (CDFG) trawl data were also compared to harbor seal diet data and were found to be significantly correlated.

Transverse compression behavior of wood in saturated steam at 150-170°C.

The transverse compression behavior of wood in high temperature (150, 160, and 170°C) and saturated steam conditions was studied. The effect of the temperature on the stress-strain response, nonlinear strain function, and relative density change was examined by a modified Hooke's law based on the load-compression behavior of flexible foams. The influence of environmental conditions during compression on the set recovery of the compression deformation was determined. It was found that temperature and moisture content affected the compression behavior of wood in saturated steam conditions. A small difference in moisture content of specimens compressed at 160 and 170°C caused approximately the same stress-strain and relative density curves with minimum temperature affect on the compression behavior. The compressive modulus of the wood and cell wall modulus were found to decrease with increasing temperature from 150 to 160°C with no change when increased to 170°C. The densification region was entered at notably lower stress levels at 160 and 170°C when compared with 150°C. The results established that temperature and moisture content did not affect the nonlinear strain function at strain levels lower than 0.63. Furthermore, it was found that the set recovery of compressive deformation decreased with increasing temperature of compression from 150 to 160°C. In addition, the results showed that compression at 160 and 170°C significantly lowered the equilibrium moisture content.
FERMI LARGE AREA TELESCOPE OBSERVATIONS OF THE VELA-X PULSAR WIND NEBULA

We report on gamma-ray observations in the off-pulse window of the Vela pulsar PSR B0833−45 using 11 months of survey data from the Fermi Large Area Telescope (LAT). This pulsar is located in the 8° diameter Vela supernova remnant, which contains several regions of non-thermal emission detected in the radio, X-ray, and gamma-ray bands. The gamma-ray emission detected by the LAT lies within one of these regions, the 2° × 3° area south of the pulsar known as Vela-X. The LAT flux is significantly spatially extended with a best-fit radius of 0. °88 ± 0. °12 for an assumed radially symmetric uniform disk. The 200 MeV to 20 GeV LAT spectrum of this source is well described by a power law with a spectral index of 2.41 ± 0.09 ± 0.15 and integral flux above 100 MeV of (4.73 ± 0.63 ± 1.32) × 10−7 cm−2 s−1. The first errors represent the statistical error on the fit parameters, while the second ones are the systematic uncertainties. Detailed morphological and spectral analyses give strong constraints on the energetics and magnetic field of the pulsar wind nebula system and favor a scenario with two distinct electron populations.
A Container-based Trusted Multi-level Security Mechanism

Multi-level security mechanism has been widely applied in the military, government, defense and other domains in which information is required to be divided by security-level. Through this type of security mechanism, users at different security levels are provided with information at corresponding security levels. Traditional multi-level security mechanism which depends on the safety of operating system finally proved to be not practical. We propose a container-based trusted multi-level security mechanism in this paper to improve the applicability of the multi-level mechanism. It guarantees multi-level security of the system through a set of multi-level security policy rules and trusted techniques. The technical feasibility and application scenarios are also discussed. The ease of realization, strong practical significance and low cost of our method will largely expand the application of multi-level security mechanism in real life.
An Empirical Analysis of the Shanghai and Shenzhen Limit Order Books

This paper investigates the market microstructure of the Shanghai and Shenzhen Stock Exchanges. The two major Chinese stock markets are pure order-driven trading mechanisms without market makers, and we analyze empirically both limit order books. We begin our empirical modeling using the vector autoregressive model of Hasbrouck and extend the model to incorporate other information in the limit order book. We also study the market impact on A shares, B shares and H shares, and analyze how the market impact of stocks varies cross sectionally with market capitalization, tick frequencies, and turnover. Furthermore, we find that market impact is increasing in trade size. Order imbalances predict the next day's returns, with small order imbalances having a negative effect.
Urban Sprawl Impact on Agricultural Lands in Irbid City, Jordan

Urban sprawl on agricultural lands is considered as one of the major problems that agricultural sector can face, especially in Irbid city. Irbid city, which is located at the north of Jordan, is one of the most important provinces in Jordan for the fertility of its soil. Most of its lands have clay soil which is suitable for cultivation of several crops. Unfortunately, the scenario of urban sprawl is continuing randomly and the percentage of agricultural land continues to decrease. This research article focuses on the agricultural lands of Irbid city and its districts, and how urban constructions will affect their areas based on statistics along the years from 1995 to 2015. In order to provide a solution to agricultural area exhaustion in Irbid governorate, this article suggests allowing adding additional floors to the current allowed floors in order to encourage vertical construction expansion rather than horizontal one.This study presents a simulation study steps to figure out the relationships between the growth of construction areas and the decline of agricultural lands. These relationships can be computed by using statistical techniques of correlation and regression analysis. Based on this analysis and computation, we tested the suggested solution, of adding more floors on the current allowed number of floors, by measuring the appropriate number of allowed floors at the same building that will delay agricultural area blocking for each Irbid district. The simulation results indicate when each district of Irbid city will be blocked before and after using the additional floors, and possible achieved delay for each district is computed. The model indicates that one alternative to reserve the agricultural lands in Irbid city for the coming 40 years is to allow buildings to grow up more than 4 floors. Therefore, this research encourages vertical construction expansion rather than horizontal one, for the coming buildings.

Aerosol impacts on California winter clouds and precipitation during CalWater 2011: local pollution versus long-range transported dust

Abstract. Mineral dust aerosols often observed over California in winter and spring, associated with long-range transport from Asia and the Sahara, have been linked to enhanced precipitation based on observations. Local anthropogenic pollution, on the other hand, was shown in previous observational and modeling studies to reduce precipitation. Here we incorporate recent developments in ice nucleation parameterizations to link aerosols with ice crystal formation in a spectral-bin cloud microphysical model coupled with the Weather Research and Forecasting (WRF) model in order to examine the relative and combined impacts of dust and local pollution particles on cloud properties and precipitation type and intensity. Simulations are carried out for two cloud cases (from the CalWater 2011 field campaign) with contrasting meteorology and cloud dynamics that occurred on 16 February (FEB16) and 2 March (MAR02). In both cases, observations show the presence of dust and biological particles in a relative pristine environment. The simulated cloud microphysical properties and precipitation show reasonable agreement with aircraft and surface measurements. Model sensitivity experiments indicate that in the pristine environment, the dust and biological aerosol layers increase the accumulated precipitation by 10–20% from the Central Valley to the Sierra Nevada for both FEB16 and MAR02 due to a ~40% increase in snow formation, validating the observational hypothesis. Model results show that local pollution increases precipitation over the windward slope of the mountains by a few percent due to increased snow formation when dust is present, but reduces precipitation by 5–8% if dust is removed on FEB16. The effects of local pollution on cloud microphysics and precipitation strongly depend on meteorology, including cloud dynamics and the strength of the Sierra Barrier Jet. This study further underscores the importance of the interactions between local pollution, dust, and environmental conditions for assessing aerosol effects on cold-season precipitation in California.
