Google Search Volume: Influence and Indication for the Dutch Stock Market

This paper studies the relationship between stock specific and market level internet search volume on stocks and the Dutch stock market, using the listed stocks in the AEX index. Internet search volume is obtained weekly from the Google Insights database for the period between January 2004 and April 2011. As introduced by earlier studies, internet searching activity is an adequate proxy for investor recognition and should therefore be relevant for modeling trading activity and stock activity. The results obtained show that Google search volume is significantly influential not only for the traded volume, but also the historical stock volatility. This significance is proven to be stable by means of a Quandt-Andrews breakpoint test.
Geometrical 2D Face Rotation by Using Gabor- tensor-based Active Appearance Model

In this paper, we present a novel face rotation methodology, which generates multi-pose faces from one single frontal face image. The proposed method has two major parts: the first part automatically detects twelve initial landmark points, on a given face image for the initialization of the facemask, and the second part applies Gabor-tensors to represent the texture and shape modelling. The proposed method uses both texture and shape information. Texture information is obtained by using spatial frequency in different sizes and orientations. Shape information is obtained by applying the Gaussian model. Experimental results on publicly available face databases show that the proposed approach gives high recognition rates on non-frontal images and it impressively outperforms the performance of other state-of-the-art methods such as active appearance model (AAM), 3D morphable models and their expanded methodologies.
Simple omega-categories and chain complexes

The category of strict omega-categories has an important full subcategory whose objects are the simple omega-categories freely generated by planar trees or by globular cardinals. We give a simple description of this subcategory in terms of chain complexes, and we give a similar description of the opposite category, the category of finite discs, in terms of cochain complexes. Berger has shown that the category of simple omega-categories has a filtration by iterated wreath products of the simplex category. We generalise his result by considering wreath products of categories of chain complexes over the simplex category.
Performance Investigations of Quasi-Yagi Loop and Dipole Antennas on Silicon Substrate for 94 GHz Applications

This paper introduces the design and implementation of two high gain Quasi-Yagi printed antennas developed on silicon substrate for 94 GHz imaging applications. The proposed antennas are based on either driven loop or dipole antennas fed by a coplanar waveguide (CPW) feeding structure. For better matching with the driven antennas, a matching section has been added between the CPW feedline and the driven antenna element. To improve the gain of either loop or dipole antennas, a ground reflector and parasitic director elements have been added. Two Quasi-Yagi antenna prototypes based on loop and dipole antenna elements have been fabricated and experimentally tested using W-band probing station (75–110 GHz). The measured results show good agreement with simulated results and confirm that the proposed antennas are working. In addition, a feed and matching configuration is proposed to enable coupling a microbolometer element to the proposed Quasi-Yagi antenna designs for performing radiation pattern measurements.
Chapter 2 Hierarchical Placement with Layout Constraints

In analog layout design, devices are required to be placed with matching, symmetry, and proximity constraints to reduce parasitic coupling effects and improve circuit performance. In addition to these basic placement constraints, there exist hierarchical symmetry and hierarchical proximity constraints due to circuit and layout design hierarchies. This chapter first introduces the hierarchical constraints induced by circuit and layout design hierarchies, and then presents a hierarchical placement approach to better consider these hierarchical constraints and effectively reduce the search space.
Unsteady aerodynamic analysis of different multi mw horizontal axis offshore wind turbine blade profiles on sst-kω model

To indicate the best airfoil profile for different sections of a blade, five airfoils; included S8xx, FFA and AH series was studied. Among the most popular wind power blades for this application were selected, in order to find the optimum performance. Nowadays, modern wind turbines are using blades with multi airfoils at different sections. SST-K-ω model with different wind speed at large scale profile applied to simulation of horizontal axis wind turbines (HAWT). The aerodynamic simulation was accomplished using Computational Fluid Dynamic (CFD) method based on the finite volume method. The governing equations apply in this simulation are the Unsteady Reynolds Averaged Navies Stocks (URANS) equations. The aerodynamic coefficients of lift and drag were calculated at different angles of attack and different wind speeds. The results are validated by Eppler code, Xfoil and experimental data of the U.S National Renewable Energy Laboratory (NREL). The results show that S818 profile is the best profile in terms of gaining the highest lift coefficient with the lowest angel of attack at the root of the blades. The results also indicated that the selected model can predicted the exact geometry with a high
Optimization and characterization of the Front Surface Field in Back-Contact Silicon Solar Cells

Interdigitated back-contact (IBC) solar cells are devices requiring very high carrier lifetimes. In this thesis, an investigation of the front-surface field (FSF) for increasing the effective lifetime of such solar cells has been carried out. Silicon samples with various doping levels have been processed, and the resulting lifetime has been characterized using photoconductance measurements, in order to obtain an understanding of FSF-optimized process parameters. The in-diffusion of dopants is assessed through the consideration of resulting dopant profiles. Simulation tools have been utilized for achieving dopant profiles, as well as for investigating the dependence of profiles on the effective lifetime.
Patterns of vegetation diversity in deep river valleys of the Bohemian Massif

The pattern of natural vegetation on non-calcareous soils in two deep river valleys of the Bohemian Massif (Vltava and Dyje rivers, Czech Republic) was analyzed in order to determine the main topographic and soil variables affecting the composition of the vegetation. Vegetation data together with topographic and soil variables were collected along transects down the slope from the upper edge to the bottom of the valley. The distribution of vegetation types within the valleys was described using cluster analysis and non-metric multidimensional scaling (NMDS). Effects of topographic and soil variables were compared using a set of canonical correspondence analyses (CCAs) with explanatory variable selection based on the Akaike Information Criterion (AIC). In order to describe the non-linear interaction between the two topographic variables, elevation and aspect, a new method (moving window CCA) was introduced. This method assessed the explanatory power of aspect at various elevations above the valley bottom. Results show that main vegetation coenoclines are correlated with two complex environmental gradients: the moisture–nutrient–soil reaction and light–temperature–continentality gradients. Soil variables are slightly better predictors of vegetation composition than topographic variables. Altogether, these variables explain 18.8–21.6% of the total inertia. Although soil development depends on topography, the variation jointly explained by both groups of variables is only 3.9–5.2%, indicating that each of these two groups of variables influences vegetation pattern in a different way. Variables selected by the most parsimonious model for the Vltava valley are aspect, soil pH, soil type fluvisol and soil depth. For the Dyje valley the same variables as in Vltava valley were selected except for soil depth, which was replaced by soil type cambisol. Aspect has a strong effect on vegetation on the middle slopes but not on the lower slopes of the valleys. The results of all analyses are similar between the two valleys, suggesting that similar patterns may also occur in other deep river valleys of mid-altitudes of the Bohemian Massif. Key-words: canonical correspondence analysis, cluster analysis, deep river valleys, non-metric multidimensional scaling, moving window CCA, vegetation-environment relationships.

COCAW: A Genome-wide Pattern Search System for Designing Microbial Probes

A few bioinformatics tools have been used to find out conserved regions as probes. We have developed a system based on a heuristic method with web interfaces to find out conserved regions against microbial genomes. The system runs in real time by using relative entropy in limited narrow regions and detecting similar regions between pair regions with local alignment. The system could be useful to find out conserved regions as genome-wide scale.
IMPROVEMENT IN GROWTH AND LEAF WATER RELATION PARAMETERS OF SUNFLOWER AND SAFFLOWER PLANTS WITH FOLIAR APPLICATION OF NUTRIENT SOLUTIONS UNDER SALT STRESS

Effect of nutrient solutions viz., KNO3, H3BO3, Fe EDTA, and their mixture applied through foliar spray on growth and water relation was assessed in sunflower and safflower plants under salt stress. Salt stress impaired growth by reducing fresh weight of both the plants. Imposition of salt stress also had adverse effects on leaf water relation parameters, relative leaf water content (RLWC), water potential (Ψw), osmotic potential (Ψs) and turgor potential (Ψp). All the water relation parameters were improved with the foliar application of nutrient solutions. The ameliorative effect of mineral nutrition on fresh biomass of both the plants under saline conditions was due to the nutrients-induced improvement in plant water status.
Seedling vigor variation among 80 recombinant chromosome substitution lines (RCSL) of barley ( Hordeum vulgare)

L. Inostroza, C. Quezada, W. Inostroza, I. Matus, M. Tapia, and A. del Pozo. 2011. Seedling vigor of 80 recombinant chromosome substitution lines (RCSL) of barley (Hordeum vulgare). Cien. Inv. Agr. 38 (1): 137-147. The seedling vigor of 80 barley recombinant chromosome substitution lines (RCSLs) was measured for selecting high seedling vigor genotypes. The RCSLs were derived from a cross between H. vulgare subsp. spontaneum and H. vulgare subsp. vulgare ‘Harrington’. The work was carried out under greenhouse conditions during the summer of 2008. The experimental design was an alpha lattice with 3 replicates. In each replicate, 40 plants were established, distributed in eight polyethylene pots containing sand as substrate, which were fertilized an irrigated. The emergence of seedlings, number of leaves and shoots, dry matter of leaves, shoots and roots and leaf area of fully expanded leaves were measured. In addition, growth indices were calculated: emergence rate, leaf appearance rate, relative leaf expansion rate, relative growth rate (RGR), net assimilation rate (NAR), leaf area ratio (LAR) and the allometric coefficient (K) between root and shoot dry matter. All calculated indices varied significantly among genotypes (P≤0.05) and some RCSLs showed better early vigor associated traits than ‘Harrington’. The dry matter accumulation 30 DAS (when the experiment ended) was significant and positively correlated with the RGR (r=0.61; P≤ 0.05) and NAR (r=0.41; P≤0.05). The K coefficient was negatively correlated with NAR (r=-0.40, P≤0.05). The genotypes with the greatest seminal vigor were the RCSLs 45, 92, 112 and ‘Harrington’, whereas the RCSLs 5, 19, 47 and 121 presented the lowest seminal vigor.
RELIABILITY OF SYMMETRY DIFFERENCES OF DYNAMIC VARIABLES DURING COUNTERMOVEMENT JUMP

The aim of the study was the determination of the reliability of symmetry differences of peak force, impulse and peak power during Countermovement Jump on a double force platform. The subjects were 12 Brazilian female professional volleyball players who performed five CMJs on a double force platform. Symmetry differences of peak force, impulse and peak power were determined. In order to verify the reliability, the Intraclass Correlation Coefficient was calculated. While symmetry difference of peak force and impulse present an ICC > 0.90, symmetry difference of peak power has only an ICC of 0.77. It can be concluded that the determination of symmetry differences by peak force and impulse during CMJ on a double force platform have higher reliability than symmetry differences of peak power.

Asymptotic behaviour of the probability of the server being idle and mean system size are discussed.
Comparative Analysis of Uncertainty Propagation Methods for Robust Engineering Design

One of the main stages of robust Engineering Design is the propagation of uncertainty in the computer analysis system. This paper presents a comparative study of various methods for uncertainty propagation, including some recently proposed derivative-free techniques called Sigma-point methods. The latter are assessed against more conventional techniques such as Monte Carlo simulation and moment propagation based on truncated Taylor series. The accuracy and computational efficiency of all methods is investigated by means of mathematical analyses and numerical examples. The solution of a robust optimization problem based on the presented methods is included. Theoretical analyses and numerical results highlight that the accuracy of robust optimization using Sigma-point methods can be enhanced with respect to that using moment propagation based on linearization without altering significantly the computational cost of a single optimization step. The paper also discusses the optimal deployment of Automatic Differentiation in conjunction with the uncertainty analysis technique chosen for the solution of the robust optimization problem and highlights the computational benefits that this yields to.
Toward an optimal control for wide field of view AO on ELT

We demonstrated the faisability of full end-to-end simulations for classical and wide field of view AO on an ELT. We show simulation results for a classical Adaptive optics systems using a standard biprocessor and octoprocessor computers with a standard control algorithm and we present the performances for a telescope varying from 8 to 42 m. We propose for optimising the performance of wide field of view system to use an optimal control approach based on the FRIM algorithm.
Screening of virulence genes in Staphylococcus aureus isolates from rabbits

Staphylococcus aureus is a versatile pathogen able to cause disease in both humans and animals. In rabbits, this bacterium infects animals of different ages, producing several purulent lesions. The ability of S. aureus to cause disease depends on a combination of virulence factors. The aim of this study was therefore to investigate the distribution of bacterial virulence determinants in 69 S. aureus isolates from rabbits. Some virulence factors (7 adhesins, 1 toxin and 1 protease) were positive in all rabbit S. aureus isolates analysed, while others (1 adhesin and 10 toxins) were always negative. The remaining virulence factors were more variable among isolates. An association between genotype and the different profiles of virulence factors was observed, but not with the type of lesion (P<0.05). One strain of each genotype was further analysed by multilocus sequence typing, generating ST121, ST96 and ST2951, determining a greater number of enterotoxins in ST121 isolates compared to ST96 and ST2951 isolates, which could justify the different pathogenicity between strains.
Assessment of Uncertainty in Ballistic Response Estimates Obtained from Ballistic Limit Testing | NIST

Ballistic limit tests are widely used to assess armor performance, particularly to determine the velocity at which half of all projectile impacts will perforate the armor, a velocity typically described as the V50. For armor designs where the armor’s performance transitions quickly from stopping all impacts to being perforated by all impacts as a test projectile’s velocity increases, the V50 can often be determined with acceptable certainty with only a small number of shots. When the transition is more gradual, such as is common with soft armor designs, significantly more testing may be necessary to determine either the V50, or the performance at other velocities, with reasonable levels of uncertainty. In the case of armor designs with gradual transitions, the estimated performance may be influenced by a variety of factors, including the number of shots used to assess the performance, the starting velocity of the shot sequence, and the model chosen to represent the armor performance. This paper describes work to assess the uncertainty in performance estimates obtained from ballistic limit testing. Monte Carlo style simulations of ballistic tests are used to asses the influences of starting velocity, shot sequence length, total shots, and armor performance on the uncertainty of performance estimates. Based on a better understanding of the performance uncertainty that is inherent in the test methods, ballistic tests can be planned such that the uncertainty is reduced to an acceptable level with a minimal amount of testing.
STRUCTURE, AGENCY AND SPACE IN THE EMERGENCE OF ORGANISATIONAL CULTURE

In this paper we address the role of the spatial environment in the construction of organizational culture. Using the example of a large and long lived museum institution we show that two quite distinct organizational cultures characterize different departmental groups. We show how these relate to organizational role and to spatial behaviour. We argue that the two groups are related to the production of scientific and social knowledge respectively, and that they are realized through relatively static ‘agrarian’ and more mobile ‘nomadic’ overt behaviours. We suggest that the organization is neither ‘fragmented’ nor ‘ambiguous’ in cultural terms, but that the twin cultures are an emergent response to conflicting organizational demands: to generate new knowledge and to provide a valued experience for the public visitor. We conclude with a methodological proposition: that the inclusion of a spatial stratum alongside the individual agent allows feedback and emergence of structures and cultures. We suggest that this offers a model for resolving the structure/agency debate in sociology without resort to conflationary theories.
Effects of potassium on temporal growth of root and shoot of wheat and its uptake in different soils

In a pot culture experiment, the root length density, potassium concentration in crop, and total K uptake by wheat (Triticum aestivum var. HD 2285) at different growth stages (CRIS-Crown Root Initiation Stage, MTS-Maximum Tillering Stage, FLS-Flag Leaf Stage and DFS-Dough Formation Stage) were determined. Wheat crop was grown in 72 pots containing 4.5 kg of three types of soils, namely Alfisol, Vertisol, and Inceptisol. Pots were divided into two sets, that is, with 50 mg kg K as basal and another 50 mg kg was top dressed at 45 days after sowing and without potassium. Optimum doses of N, P and other macro-and micro-nutrients were given to the crop. At different stages of wheat growth (22, 41, 69, and 87 days after germination), the shoot was harvested and the soil in the pot was screened carefully under moist condition to collect total roots and measuring the root volume and mean root diameter. Using root volume and mean diameter of root, total root length and then root length density were calculated. Results show that the wheat dry matter yields increased gradually with crop age and it was more in Inceptisol followed by Vertisol and Alfisol. Potassium deficiency decreased total root length (TRL) and root length density (RLD) in the last stages of wheat growth particularly in Vertisol and Alfisol. Potassium concentration in wheat at different stages of crop growth was found to be less in Alfisol than in Vertisol and Inceptisol. At different stages of wheat growth, potassium uptake (mg pot) was found to be less in Alfisol than in Vertisol and Inceptisol. The uptake values increased sharply with the age of the crop up to 69 days after germination (FLS), but the rate of potassium accumulation showed a gradual decrease thereafter, in soils, which received optimum amount of potassium.
