Novel Compact UWB Frequency Selective Surface for Angular and Polarization Independent Operation

This paper deals with a novel miniaturized FSS with wide stop band characteristics for UWB applications. The proposed FSS consists of garland like design printed on either side of the dielectric substrate. The design provides a bandwidth equal to 3.5GHz at i20dB reference level of insertion loss which lies within the UWB range. The design delivers stable response for various angular incidences. In addition to this, the symmetrical nature of the FSS holds identical response for both TE and TM Mode of polarization. The proposed geometry is fabricated and its simulated results are validated with measurements. A comprehensive analysis is made by adjusting various parameters associated with the proposed design.
Intermacromolecular complexation due to specific interactions 4. The hydrogen-bonding complex of vinylphenol-containing copolymer and vinylpyridine-containing copolymer

The complexation of poly(styrene-co-vinylphenol) (STVPh) and poly(styrene-co-vinylpyridine) (STVPy) in nonaqueous solution was investigated with emphasis on the effect of the hydroxyl and pyridyl contents in the component polymers. Viscometry, nonradiative energy transfer fluorospectroscopy, and dynamic laser light scattering have led to the same conclusion, i.e., STVPh and STVPy blend can form an interpolymer complex due to hydrogen bonding in tetrahydrofuran, butanone, and chloroform, provided the contents of the hydroxyl and pyridyl reach certain respective levels. The size distribution of the complex aggregates is relatively narrow with a peak size 1 order of magnitude larger than those of the component polymer coils. The minimum content of the interaction groups required for complexation strongly depends on the solvent used. Chloroform and butanone are almost inert for hydrogen bonding between the polymers, tetrahydrofuran has a substantial influence on complexation, and addition of N,N-dimethylforma.
Feature Selection for High-Dimensional Individual and Ensemble Classifiers with Limited Data

There are many feature selection algorithms and many classification methods available to choose from in order to successfully and accurately learn a data set. This work focuses on the merits of dimensionality reduction and the comparative analysis of select techniques. Relief-f, Classification and Regression Trees (CART), and Analysis of Variance (ANOVA) are used to select subsets of features within four real world and one artificial data set. The three are then combined to produce and ensemble feature subset. These results are used as input for feed forward artificial neural networks (FFANN), Naïve Bayes, support vector machines (SVM), and an ensemble the three. Averaged accuracy percentages are used to analyze the performance of each dimensionality reduction approach. It was found that the ensemble approach to feature selection produced generally more accurate results overall. Average accuracies included 96.5% of correctly identified benign and malignant breast cancer tumors and 89.5% of appropriately labeled splice junctions within DNA sequences, while reducing the data sets from nine features and sixty features respectively to five representative features each.
Cougar kill rate and prey composition in a multiprey system.

Abstract Assessing the impact of large carnivores on ungulate prey has been challenging in part because even basic components of predation are difficult to measure. For cougars (Puma concolor), limited field data are available concerning fundamental aspects of predation, such as kill rate, or the influence of season, cougar demography, or prey vulnerability on predation, leading to uncertainty over how best to predict or interpret cougar–ungulate dynamics. Global Positioning System (GPS) telemetry used to locate predation events in the field is an efficient way to monitor large numbers of cougars over long periods in all seasons. We applied GPS telemetry techniques combined with occasional snow-tracking to locate 1,509 predation events for 53 marked and an unknown number of unmarked cougars and amassed 9,543 days of continuous predation monitoring for a subset of 42 GPS-collared cougars in west-central Alberta, Canada. Cougars killed ungulates at rates near the upper end of the previously recorded range, .
The SUrvey for Pulsars and Extragalactic Radio Bursts - I. Survey description and overview

We describe the Survey for Pulsars and Extragalactic Radio Bursts (SUPERB), an ongoing pulsar and fast transient survey using the Parkes radio telescope. SUPERB involves real-time acceleration searches for pulsars and single-pulse searches for pulsars and fast radio bursts. We report on the observational set-up, data analysis, multiwavelength/messenger connections, survey sensitivities to pulsars and fast radio bursts and the impact of radio frequency interference. We further report on the first 10 pulsars discovered in the project. Among these is PSR J1306-40, a millisecond pulsar in a binary system where it appears to be eclipsed for a large fraction of the orbit. PSR J1421-4407 is another binary millisecond pulsar; its orbital period is 30.7 d. This orbital period is in a range where only highly eccentric binaries are known, and expected by theory; despite this its orbit has an eccentricity of 10-5.
Accurate argon cluster-ion sputter yields: Measured yields and effect of the sputter threshold in practical depth-profiling by x-ray photoelectron spectroscopy and secondary ion mass spectrometry

Argon Gas Cluster-Ion Beam sources are likely to become widely used on x-ray photoelectron spectroscopy and secondary ion mass spectrometry instruments in the next few years. At typical energies used for sputter depth profiling the average argon atom in the cluster has a kinetic energy comparable with the sputter threshold, meaning that for the first time in practical surface analysis a quantitative model of sputter yields near threshold is needed. We develop a simple equation based on a very simple model. Though greatly simplified it is likely to have realistic limiting behaviour and can be made useful for estimating sputter yields by fitting its three parameters to experimental data. We measure argon cluster-ion sputter yield using a quartz crystal microbalance close to the sputter threshold, for silicon dioxide, poly(methyl methacrylate), and polystyrene and (along with data for gold from the existing literature) perform least-squares fits of our new sputter yield equation to this data. The equation performs well, with smaller residuals than for earlier empirical models, but more importantly it is very easy to use in the design and quantification of sputter depth-profiling experiments.
Mixing characteristics of a notched-rectangular jet and a circular jet

This paper reports an experimental investigation of the near-field mixing characteristics of two single air/air turbulent jets issuing, respectively, from a notched-rectangular orifice and a circular orifice with identical opening areas. Planar particle image velocimetry (PIV) was used for measurements of the velocity field. Present experiments for the two jets were conducted under the same nominal conditions with the exit Reynolds number of 72,000. Consistent with previous investigations of other noncircular jets, the notched jet is found to have an overall superior mixing capability over the circular counterpart. Immediately downstream of the nozzle exit, it entrains, and then mixes with, the surroundings at a higher rate. This jet has a shorter potential core and higher rates of decay and spread than the circular jet. The phenomenon of axis switching is also found to occur in this jet.
The Predicaments of Non-Residential Students in Ghanaian Institutions of Higher Education: A Micro-Level Empirical Evidence

This paper in the field of capacity building and students’ affairs used the external survey assessment techniques of the probit model to examine the predicaments of non-resident students of the College of Technology Education, University of Education, Winneba. Considering the very limited residential facilities and the growing demand for tertiary education, being a tertiary residential student is gradually becoming a mirage in most Ghanaian public universities. This paper argued that the College of Technology Education, either through direct provision or indirectly through private providers, should take all steps to ensure that future non-residential student housing projects are conceived as an integral part of the academic community by taking direct and pragmatic steps to mitigate against the difficulties and problems non-resident students encounter at their various places of residence. Keywords: non-resident students, residential facilities, private providers, higher education,
Modeling D-Forms

In this paper, we present a computational method for modeling D-forms. These D-forms can directly be designed only using our software. We unfold designed D-forms using a commercially available software. Unfolded pieces are later cut using a laser cutter. We obtain the physical D-forms by gluing the unfolded paper pieces together. Using this method we can obtain complicated D-forms that cannot be constructed without a computer.
The Relationship between Organizational Resources and Systems: An Empirical Research

Organizational resources and systems have been conceptualized as to be able to significantly predict the level of competitive advantage. This research empirically examined the importance and emphasis placed on the relationship between organizational resources and systems, especially towards the attainment of firms’ competitive advantage. This research was conducted among manufacturers listed in the Federation of Malaysian Manufacturers Directory 2008. A cross-sectional study using structured questionnaire was used to obtain responses from the manufacturers. From the subsequent actual survey, 127 respondents replied and completed the questionnaire (12.7% response rate). The large correlation (r = 0.72) implies a strong positive relationship between the organizational resources and systems. As for the variance shared between these two variables, the coefficient of determination (r² = 0.52) suggests that organizational resources help to account for nearly 52% of the variance in systems, and vice versa. The theoretical implication of this study is that it supports and extends the RBV of competitive advantage by illustrating the need for systematic management of resources towards attaining competitive advantage.
THE EXPERIENCE OF THE AGENT-BASED SIMULATION SYSTEM DEVELOPING

This paper discusses the problems of the agent-based simulation system design. It is well known that agent models extend the capabilities of simulation for solving some problems that can’t be solved by the methods of system dynamics and discrete event simulation. Particular attention in the design and the implementation of agent-based simulation authors pay to the problems of distributed simulation and the problems of intelligent agent’s implementation and the use of ontologies at all stages of the simulation experiments.
Radiocarbon Dating Lime Lumps and/or Binder carbonate in Historical Mortars?

Lime lumps and bulk mortars show different kinds of C contamination when analyzed in several CO2 fractions isolated from the effervescence of an ongoing hydrolysis reaction. Age profiles of both materials are therefore highly complementary and together they can provide a reliable dating. Furthermore, they can also reveal the complexity of the C distribution and thus prevent over-interpretation of the data. The lime lump vs bulk mortar dating data presented here has been collected over 22 years and only a small fraction of the results has so far been published internationally. Since there has been an increasing interest in mortar dating over recent years with a special focus on lime lumps and since many laboratories have just started with mortar dating experiments, we want to present some of the extensive data that already exist. Earlier published data from 15 lime lumps including 34 C measurements from sequential dissolution and new data from 17 lime lumps with 43 C measurements will be presented. The samples are from Medieval Finland and Sweden, from Classical Rome and Medieval Italy and from the Roman Jerash (Gerasa), Jordan.
A study of personal beliefs of advertising and attitudes towards advertisements: Pollay and Mittal (1993) revisited

This study involves a survey of university students and focuses on the personal beliefs and uses of advertising identified in Pollay and Mittal’s (1993) seminal paper, i.e., Product Information, Social Role/Image, and Hedonic/Pleasure. Our results suggest that respondents’ attitudes towards advertisements is most strongly driven by the Hedonic/Pleasure factor of advertising, followed by its Product Information role, but is unaffected by the Social Role/Image function of advertising. Our structural equation modelling results suggest that there has been an increase in the importance of the Hedonic/Pleasure role of advertising since Pollay and Mittal’s (1993) original study. In addition, the measurement diagnostics for these three constructs from our modelling suggest that there may be a need to revisit these items, and to develop and validate new and better measures of them. _____________________________________________________________________________________
Existence of the Day-of-the-week Effect in FTSE Bursa Malaysia

This paper investigates the existence of day-of-the-week effect for ten FTSE Bursa Malaysia indices. Standard procedure of determining calendar anomaly with additional GARCH related models are employed to determine the significance of the day-of-the-week effect. Results suggest that the day-of-the-week effect only exist for the FTSE Bursa Malaysia MESDAQ Index. However, the effect might be due to changing volatility since the negative and lowest Monday return does not appear to be significant in the EGARCH model. ABSTRAK Kajian ini mengkaji kewujudan kesan hari-dalam-minggu bagi sepuluh indeks FTSE Bursa Malaysia. Prosedur piawai bagi penentuan keganjilan kalendar beserta tambahan model berkaitan GARCH telah digunakan untuk menentukan kesignifikanan kesan hari-dalam-minggu. Hasil kajian mencadangkan bahawa kesan hari-dalamminggu hanya wujud bagi indeks MESDAQ FTSE Bursa Malaysia. Walau bagaimanapun, kesan tersebut mungkin disebabkan oleh perubahan kemeruapan kerana pulangan pada hari Isnin yang negatif dan terendah adalah ternayta tidak signifikan dalam model EGARCH.
A Weighted ML-KNN Model for Predicting Users’Personality Traits

Gaining insight into human personality and its impact on human behavior is very valuable in many applications, such as web information credibility prediction. In this paper, we explore using weighted ML-kNN model for automatic recognition of personality traits of web users, based on a given composition text. After extracting features through analysis of the content of user’s Essays statues updates, we discretize contiguous attribute using Kohonen’s feature-map algorithm, and assign weight to extracted features based on information entropy. The Essays dataset is partitioned into training dataset and test dataset. For a given test user, the weighted distance between test user and training user is calculated, and based on which the nearest neighbors are identified. The personality traits of test user are then predicted by using ML-kNN algorithm. Our experiment on the Essays dataset shows expected positive results.
EMPIRICAL DEMAND ANALYSIS FOR LONG - LENGTH ROUNDWOOD (SAWLOGS) IN GREECE

In Greece and internationally, the roundwood is one of the most important forest products as it is used widely in construction and building sector. In this study the process of wholesale long-length roundwood (>2m) price determination is depicted in the form of an inverse demand system. The empirical application based on five species of long-length roundwood using yearly data for auctions providing reasonable and promising results. The own-quantity flexibilities suggest that the responses of prices to own-quantity changes are inelastic while Allais coefficients suggest substitutability between the different species of log-length roundwood.
Corporate Governance, Intellectual Capital and Firm Performance

This paper investigates the impact of corporate governance and intellectual capital on firm performance in Indonesian-listed firms. Using a balanced-panel of 120 Indonesian-listed firms, this study employs a balanced panel method, using non linier IV 2SLS and non linier IV-GMM. All variables, apart from commissioners, directors, education and capital employed efficiency exhibit a non significant impact on Tobins’Q, while all variables are statistically non significant for ROA. The findings are less conclusive than that of previous studies in developed countries. This study provides recent evidence for the corporate governance and intellectual capital in affecting firm peformance of listed-firms in Indonesian Stock Exchange. Though most listed-firms in Indonesia is owned by group or family, the appointment should be strictly complied to the regulations set, as current evidence indicates that independent commissioners and directors have no impact on firm performance, hence an awareness of good corporate governance conduct should be massively disseminated.
Antimicrobial Activity of Aqueous Extracts of Maytemus putterlickoides, Senna spectabilis and Olinia usambarensis on Selected Diarrhea-Causing Bacteria

Diarrhea is one of the leading causes of morbidity and mortality among children under the age of five years in the developing world. Opportunistic bacteria have been identified as the major cause of diarrhea in HIV infected patients. Treatment of these emerging and re-emerging strains of diarrhea causing bacteria has become difficult due to their increased tolerant to the present available antibiotics. There is need to identify and develop alternative drugs, which are effective, affordable and easily accessible to diarrhea patients. However, there is no record in the literature of the antibacterial activity of these plants. The objective of this study was to enhance understanding of the efficacy of ethno-medical materials in the management of diarrhea. Antibacterial activity was evaluated by determination of Minimum Inhibition Concentration and the Minimum Bactericidal Concentration of the plant extracts against the diarrhea causing bacterial. Phytochemical screening for bioactive compounds was undertaken using standard qualitative methods. Maytenus putterlickoides (roots) and Senna spectabilis (leaves) were active against Salmonella typhi, Shigella flexineriae and Shigella Dysenteriae with zone of inhibition ranging 9.2-15.8 mm. Olinia usambarensis (leaves) had antimicrobial activity against several bacterial isolates with zone of inhibition ranging 9-15 mm. Alkaloids, tannins, anthrocyanins, triterpenes and steroids, saponins, flavanoids, coumarins and reducing sugars were present in the three plant extracts. These phytochemicals account for the antibacterial activity of the extracts against the bacterial strains.
INVESTMENT DECISION SUPPORT SYSTEM FOR HIGH QUALITY CONTROL POSTS IN EUROPEAN UNION

In 2010 an EU subsidy program started to create high quality control posts in Europe. Control posts are companies offering facilities for animals to rest and eat during long distance transport. They also offer facilities for trucks, drivers and competent authorities. A decision support program has been developed to support owners of control posts with their investment plan. The aim of this computer program is to calculate what increase in truckloads or in price per truckload is needed to justify the investment plans. The program was tested at two control posts participating in the EU project in Poland2. Both owners appreciated the added value of the program and suggested some improvements.
Economic Multipliers and Mega-Event Analysis

Critics of economic impact studies that purport to show that mega-events such as the Olympics bring large benefits to the communities “lucky” enough to host them frequently cite the use of inappropriate multipliers as a primary reason why these impact studies overstate the true economic gains to the hosts of these events. This brief paper shows in a numerical example how mega-events may lead to inflated multipliers and exaggerated claims of economic benefits.
Annealing of Aluminum Alloy Wire with an Atmospheric Pressure Plasma

RF discharge argon plasma was utilized to thermal annealing of stranded aluminum alloy wire under atmospheric pressure (AP). Experimental results demonstrated that, in additional to surface cleaning, the AP plasma could also be applied to effectively treating the bulk of a material by using the thermal energy of the plasma. Dependences of the mechanical properties of the wire, the wire temperature, and the energy efficiency on annealing time and gas flow rate were investigated. Heating mechanism in the RF plasma annealing process was proposed.
Investigating factors affecting the quality of local cultural spaces applying the AHP technique

Due to audiences’ diversity, local cultural spaces have the highest share in residents’ mass life. Therefore, these spaces are the necessary environment for social relations and face-to-face communication of residents of urban area. If these are well qualified, welfare would be promoted. This study aims at identifying and evaluating factor influencing quality of local cultural spaces and aims to recognize and prioritize the factor using AHP analytical hierarchical process so as to promote them. This applied study has a descriptive-analytical basis with a population of 75 experts in urban planning and cultural matters and academic staff used as participants. First, the quality criteria of cultural space was determined based on the 4 main criteria and 26 sub-criteria in a hierarchical tree. Then experts were asked to score the major and minor criteria and specify their priorities based on paired comparisons. Applying the Expert Choice which implements the AHP, the weights of each criterion and sub-criterion were estimated respectively. Finally, according to the study’s aim, priorities were determined. The results obtained showed that the physical criteria, weighting 0.557, got the first priority and it was followed by social (0.162), economic (0.148) and environmental (0.133) criteria which got the second to the fourth rank. The sub-criteria affecting the "quality of cultural spaces" of the physical structure included safety, human scale and availability.
A Family of Coherence-Based Multi-Microphone Speech Enhancement Systems

This contribution addresses the problem of additive noise reduction in speech picked up by a micro- phone in a noisy environment. Two systems belonging to the family of coherence-based noise cancellers are pre- sented. Suggested systems have the modular structure using 2 or 4 microphones and suppress non-stationary noises in the range of 4 to 17 dB depending on the chosen structure and noise characteristics. The common proper- ties are acceptable noise suppression, low speech distor- tion and residual noise.
A Literature Survey based Study of Deflections of the Robot Hands for Intelligent Systems

Generally dumb people use sign language for communication but it has been very difficult to create communication with them as others do not understand sign language very well without learning. Therefore we have try to develop an electronic device that can translate sign language into speech in order to make the communication take place between the mute communities with the normal people easily, a Wireless data gloves is used which is a normal cloth driving gloves fitted with flex sensors along the length of each finger and the thumb. Mute people can use the gloves to perform hand gesture and it will be converted into speech so that normal people can understand their expression. This paper provides the map for developing such a digital glove. It also analyses the characteristics of the device and discusses future wok. A foremost goal of this paper is to provide readers with a basis for understanding glove system technology used in biomedical science.
