Attention-Based Context Aware Reasoning for Situation Recognition

Situation Recognition (SR) is a fine-grained action recognition task where the model is expected to not only predict the salient action of the image, but also predict values of all associated semantic roles of the action. Predicting semantic roles is very challenging: a vast variety of possibilities can be the match for a semantic role. Existing work has focused on dependency modelling architectures to solve this issue. Inspired by the success achieved by query-based visual reasoning (e.g., Visual Question Answering), we propose to address semantic role prediction as a query-based visual reasoning problem. However, existing query-based reasoning methods have not considered handling of inter-dependent queries which is a unique requirement of semantic role prediction in SR. Therefore, to the best of our knowledge, we propose the first set of methods to address inter-dependent queries in query-based visual reasoning. Extensive experiments demonstrate the effectiveness of our proposed method which achieves outstanding performance on Situation Recognition task. Furthermore, leveraging query inter-dependency, our methods improve upon a state-of-the-art method that answers queries separately.

The algorithm developed in this paper is quite straightforward and easy to understand and also present an essential way out to the decision maker for attaining an optimal sequence of jobs. The algorithm developed in this paper is validated by a numerical illustration.
Immobilization of Na,K-ATPase isolated from rat brain synaptic plasma membranes

Rat brain Na,K-ATPase partially purified by SDS from synaptic plasma mem- branes (SPM) was immobilized by adsorption on nitrocellulose (NC), polyvinylidene fluo- ride (PVDF) and glass fiber (GF) membranes. Partial SDS solubilization increased the en- zyme activity by 40 %. With regard to the preservation of the enzyme activity, nitrocellulose was shown to be the optimal support for the immobilization. The enzyme showed the high- est percentage activity (14 %) after 30 min of SPM adsorption, at 20 oC under the vaccum, with 25 g of proteins per NC disc filter. In addition, adsorption on NC stabilizes the Na,K-ATPase, since the activity was substantial 72 h after adsorption at 20 oC. After adsorp- tion, the sensitivity of the enzyme to HgCl 2 and CdCl 2 inhibition was higher. The results show that immobilized Na,K-ATPase SPM can be used as a practical model for the detection of metal ions in different samples.
AgileDCN: An Agile Reconfigurable Optical Data Center Network Architecture

This paper presents a detailed examination of a novel data center network (DCN) that can satisfy the high capacity and low latency requirements of modern cloud computing applications. This reconfigurable architecture called AgileDCN uses fast-switching optical components with a centralized control function and workload scheduler. By providing a highly flexible optical network fabric between server racks, very high network efficiencies can be achieved even under imbalanced loading patterns. Our simulation results show that, at high (70%) loads, TCP flow completion times in the AgileDCN are significantly lower than in an equivalent electronic leaf-spine network.
International Journal of Innovative Technology and Exploring Engineering (IJITEE)

Wireless technologies are aiming to improve data rates along with reliability using Multiple Input and Multiple Output(MIMO) systems. The major performance parameter for advanced systems is Bit Error rate (BER). Researchers are working for minimizing the BER for data communication. This paper presents the BER performance of turbo coded Multiple Input Multiple Output (MIMO) system in Nakagami channel. MIMO system is realized using Space Time Block Codes. System performance is analyzed for M-ary Quadrature Amplitude Modulation (QAM) in Nakagami channel. System is implemented using MATLAB code. 4QAM system performs better as far as BER is concerned. The implemented turbo coded system outperforms the uncoded system in case of BER performance. This system can be used for improved performance of data communication in LTE and WiMax.
Organizational Determinants in Adoption of Open Source Software (OSS) in Institutions of Higher Learning: A case of Innorero University, Kenya.

With the rapid development of Information and Communication Technologies (lCTs) use in public and private sectors and the fast growing Internet access, Institutions of higher learning have no choice but to adopt these technologies if they have to be relevant in this information age. This study aimed at examining the organizational determinants affecting the adoption of open source software in institution of higher learning in Kenya with special reference to Inoorero University. The specific objectives of the study were; to find out how organizational size affects the use of OSS, to examine the effect of organizational structure on the adoption of OSS, to assess the effect of organizational culture on the adoption and use of OSS in the institution of higher learning and lastly to assess the role of the management in the adoption of OSS in institution of higher learning in Kenya. The study used descriptive survey in carrying out the investigation. This study adopted comprehensive qualitative analysis where a careful and complete scrutiny and understanding of the situations in the institutions was done. The target population of the study consisted of; students, teaching staff and management at Inoorero University, School of Information Technology who were 500 in total. The study used both the stratified sampling techniques and the simple random sampling in the determination of the sample. A sample of 150 respondents was selected from whom data was collected. The study used the questionnaire to collect the data of which 137 were returned and analysed. The Cronbach's Alpha reliability coefficient was used to test the reliability of the instruments which yielded a value of 0.891, hence the instruments were considered reliable. The data collected was summarized and presented using both descriptive such as frequencies and percentages and inferential statistics such as the correlation and regression analysis. The results show that the adoption of OSS in the institutions of higher learning was determined by organizational size, organizational structure, role of management and the organizational culture. The correlation analysis showed that organizational size had the highest influence in the adoption of OSS in the learning institution. From the regression analysis it showed that the four factors considered in the study influenced the adoption of OSS by only 22.5%. The study recommends that if the results of this research are implemented by the government of Kenya they can be beneficial to the students and staff of the university and shall form a basis for more research involving the public and private sectors in Kenya. The results would also help in ensuring quality and standardization of the various educational programs at the university level
Parâmetros genéticos e eficiência relativa de seleção para a produção de leite no dia do controle para vacas da raça Holandesa

To verify the possibility of the Test Day Model Methodology (PLCD) to be used in genetic evaluations, records on 33,775 monthly test day were studied. The records were obtained from 4,241 first lactation Holstein cows, sired by 561 bulls, distributed in 23 herds in the state of Rio Grande do Sul, from 1992 to 2001. The (co)variance components were estimated by Restricted Maximun Likelihood method, on animal model. The model considered PLCD and 305 days yield (PL305), as functions of the aditive genetic direct, permanent environmental, and residual random effects; the contemporary group and the herd as fixed effects and the covariables, age of cow at birth and calving-first control interval (only for PLCD), linear and quadratics effects. The high heritabilities for PLCD and the high genetic correlations estimated among PLCD and PL305 suggest that PLCD can be used in genetic evaluation of Holtein cows. The relative selection efficiency for PLCD, as a selection criteriun, was higher than that for PL305.

Welfare Considerations of Triploid Fish

Aquaculture production continues to increase to satisfy global demand, and as such, issues relating to its environmental sustainability and the welfare of fish are becoming more prominent within society. Sterile triploid fish (possessing one additional chromosome set to the more natural diploid state) are in use in aquaculture and fisheries management to avoid the problems associated with unwanted early sexual maturation and genetic interactions between wild and cultured fish. Triploids are physiologically and behaviorally similar to diploids, although ploidy effects do exist. This review focuses on the welfare of triploid fish within aquaculture and fisheries management. The main conclusions are that triploids appear more susceptible to temperature stress, have a higher incidence of deformities, and are less aggressive than their diploid counterparts. However, considerable knowledge gaps exist in triploid physiology and performance; therefore, triploid requirements for water quality, nutritional requirements, stocking densities, and slaughter methods cannot be fully assessed. In addition, other than growth and survival, no information exists on the performance of triploids when released into natural environments, and this is of considerable concern, as triploids are commonly used in catch-and-release fisheries. These matters become more pressing with today's increased emphasis on animal welfare.
Genetic Diversity, Correlation and Path Analysis for Yield and Yield Components of Pea (Pisum sativum L.)

Forty six pea genotypes were evaluated for thirteen morphological characters during Rabi season, 2010 at Sher-e-Bangla Agricultural University, Dhaka, Bangladesh. Analysis of variance (ANOVA) test revealed significant differences among the genotypes for all the traits. Days to first flowering, plant height, branches plant , pod length, hundred seed weight, pods plant , seeds plant and seed yield plant exhibited that they 1 1 1 1 were controlled by additive gene action and selection for the improvement of these traits would be rewarding. The phenotypic variance was higher than the corresponding genotypic variance for all the characters. All the characters showed moderate to low phenotypic and genotypic coefficient of variation. Genotypic coefficient of variation was the highest for hundred seed weight (37.24) followed by number of branches plant (15.96) 1 and seeds plant (15.27). Hundred seed weight had the highest heritability (95.97). Pod length, hundred seed 1 weight, pods plant and seeds plant showed significant positive genotypic and phenotypic correlation with 1 1 seed yield. In path analysis, plant height, internode length, hundred seed weight, number of seeds pod and 1 seedsplant showed positive direct effect on yield. Considering genetic variability, correlation and path 1 analysis, emphasis should be given on pod length, seeds pod , seeds plant and hundred seed weight during 1 1 breeding program to improve seed yield of pea.
Spatial Variation in Food-Limited Growth of Juvenile Greenback Flounder, Rhombosolea tapirina: Evidence from Otolith Daily Increments and Otolith Scaling

Growth rates of juvenile flounder, Rhombosolea tapirina, determined from daily increment number, and the relationship between otolith and fish sizes (otolith scaling), were compared between two adjacent areas. Swan Bay, Victoria, a sheltered bay with a well-developed seagrass-detrital system, supports higher populations of prey and feeding rates of juvenile flounder than Port Phillip Bay, an area more exposed to waves and tidal currents. Temperature was significantly higher in Swan Bay (though generally less than 1 °C). Growth rates determined from daily increment number were similar within bays, but significantly different between bays. The pooled growth rate for Swan Bay (0.29 mm∙d−1) was significantly higher than for Port Phillip Bay (0.17 mm∙d−1). The same pattern was found for otolith scaling. Most of the variation in growth rates between the two bays was apparently related to food supply. A laboratory experiment indicated that otolith growth rate had a minimum level which was independent of somatic .
Influence of Roads, Rivers, and Mountains on Natal Dispersal of White-Tailed Deer

Abstract Natural and anthropogenic landscape features, such as rivers, mountain ranges, and roads can alter animal dispersal paths and movement patterns. Consequently landscape, through its effects on dispersal, may influence many ecological processes, including disease transmission, invasion dynamics, and gene flow. To investigate influences of landscape features on dispersal patterns of a large mammal, we captured and radiomarked 363 juvenile male white-tailed deer (Odocoileus virginianus), including 212 confirmed dispersers, in 2 topographically dissimilar study areas in Pennsylvania, USA. Dispersal azimuths were uniformly distributed in the western study area (WSA), where there was irregular, hilly topography. Mean dispersal azimuths paralleled ridge direction in the eastern study area, where long parallel ridges were aligned northeast–southwest. Major roads in both areas and a large river in the WSA were semipermeable barriers to dispersal of juvenile males; dispersal paths were less likely to intersect these linear features. Dispersal movements were direct and brief, typically lasting <12 hours. For all dispersers, we found no evidence for preference or avoidance of establishing adult, postdispersal ranges in proximity to roads; however, deer that encountered roads near the terminus of their dispersal path were more likely to stop on the near side. Further, for deer that established postdispersal home ranges near major roads, these features influenced range placement such that locations were typically clustered on one side of the road. The influence of roads, rivers, and mountains on dispersal paths and postdispersal locations of white-tailed deer suggest that landscape-specific features should be considered in conservation and management of this and possibly other species of large mammals.
Physicochemical Characterization of Starches from Amaranthus Cruentus Grains

The physicochemical properties of starches isolated from three cultivars (Mexican, African and A200D) of Amaranth cruentus grains were studied. The yield of starch was in the range 29–38.3% on a whole grain basis. The starch granules were polygonal with smooth surfaces. The granule size was in the range 0.75–1.5 μm for all three cultivars. The free, bound and total starch lipids ranged from 0.05 (b 0.07%, from 0.16 to 0.28 and from 0.20 to 0.35%, respectively. The total amylose content ranged from 3.9 to 5.7% of which 10.3 to 15.8% were complexed by native lipid. The X-ray pattern was of the “A” type. The intensities of the major diffraction patterns followed the order: Mexican > African > A200D. The swelling factor followed the order: A200D > African > Mexican. All three starches exhibited identical pasting temperatures. However, they differed with respect to the highest viscosity reached during the heating cycle (Mexican > A200D > African), viscosity at 95°C (Mexican > A200D > African), the extent of breakdown (African > A200D ∼ Mexican) in viscosity (during the holding cycle at 95°C) and setback (A200D > African > Mexican). The gelatinization temperature ranges were 72.2–91.0°C (Mexican), 69.8–84.1°C (African) and 69.0–83.6°C (A200D). The enthalpy of gelatinization (J g−1) were: 11.8 (Mexican) 12.3 (African) and 14.5 (A200D). The extent of acid hydrolysis (2.2 N HCl at 35°C) followed the order: A200D > African > Mexican. The susceptibility of the starches towards hydrolysis by porcine pancreatic α-amylase followed the order: African > A200D > Mexican. The freeze-thaw stability followed the order: Mexican > African > A200D. The results of this study showed that bonding forces within the amorphous and crystalline regions are most pronounced in the Mexican cultivar.

Analysis of Stress Asymmetric Distribution Law of Surrounding Rock of Roadway in Inclined Coal Seam: A Case Study of Shitanjing No. 2 Coal Seam

Asymmetrical deformation and failure characteristics of the surrounding rock at the right-angled trapezoidal roadway in the Shitanjing No. 2 mining area has created great difficulties in the stability control and support of the roadway. First, numerical simulations were applied to systematically analyze the distribution rules for vertical stress, horizontal stress, and failure characteristics of the roadway. Furthermore, verifications were conducted via laboratory model tests and practical engineering application. The results show that the two walls of the roadway, the roof, and the sharp corners demonstrate obvious asymmetric stress concentrations. The peak value of stress concentration in the low side (right wall) is significantly greater than that in the high side (left wall), and the distances from high and low sides of roadway to both walls of the roadway are obviously different. The two sharp corners, which are symmetrical along the same direction of the coal seam inclination, show obvious compressive stresses, while the opposite directions show obvious tensile stress regions at both sharp corners; further, maximum values of the compressive and tensile stresses appear at the two corners of the roadway roof, and their magnitudes vary with the change in inclination and ground stress.
A Study on Pullout Test of Root Subjected to Axial Load

Vegetation can enhance the stability of slopes by increasing the shear resistance of the soil. Shear stress applied to the soil matrix is resisted by the pullout strength of the roots via the friction at contact points between the soil and the roots. The effectiveness of root reinforcement depends on interface friction between soil and roots. In this study, tests were carried out on Indigofera amblyantha Craib roots, by measuring resistance as they are pulled out of the soil where the soil has varying dry densities. The results reveal three phases in the relationship between the pullout force and the slippage of the roots, i.e. (1) steep rise, (2) steep fall, and (3) gradual decline. In the first phase, the pullout force is increasing sharply and linearly up to a maximum when the slippage is about 10mm. With continued slippage, the required pullout force decreases significantly and nonlinearly in up and down fluctuations. Eventually, the pullout force reaches zero. For soil with a given dry density, the maximum pullout force increases linearly with increasing root diameter, and the correlation coefficient is greater than 0.9. Further, for a root with a given diameter, the maximum pullout force increases with increasing soil dry density. When the root breaks on pulling, it is called tensile failure; when the root is fully pulled out, it is called friction failure. The mode of failure for all roots is friction failure, for soil with dry densities of 1.35 g/cm3, 1.45 g/ cm3, and 1.55 g/cm3. For soil with a dry density of 1.65 g/cm3, and root diameter under 0.716 mm, the observed failure mode is generally tensile; for diameters over 0.716 mm, the failure mode changes to friction; that is, thin roots break, thick roots get pulled out.
