Authors: V Appa Rao B. , A S N V Prasad K. 
Published: April 2019

In this work, we develop the criteria for existence of Î¨- bounded solutions of system of linear dynamic equations on time scales. The advantage of results in this dynamical system is it unifies discrete as well as continuous systems. Initially, we develop if and only if conditions for the existence of at least one Î¨-bounded solution for linear dynamic equation yâˆ†(Ï„ ) = P (Ï„ )y +g(Ï„ ), for each Î¨- delta integrable Â Lebesgue function g, on time scale T +. Later, we obtain asymptotic nature of Î¨-bounded solutions of dynamical system. Also we provided the examples for supporting the results.AMS Subject Classification: 74H20, 34N05, 34C11Â Â

Published: April 2019

Extraction of Roads, Rivers and other map objects is an important step in many military and civilian applications. In this process the information is extracted which possess high efficiency and accuracy and is fed into GIS (Geographical Information System). In this paper, we have explored different algorithms with better efficiency and accuracy. Road extraction can take place for two kinds of roads namely: urban and non-urban roads. Urban roads are more complex to analyze because of their architectural complexity, occlusions created by trees, heavy traffic and extensive network, whereas non-urban roads are easier to analyze because of less structural Â Â Â Â Â Â Â Â complexity. The proposed algorithm exploits the properties of road segments to develop customized operators to accurately derive the road segments. The customized operators include directional morphological Â Â Â enhancement, directional segmentation and thinning. The proposed algorithm is systematically evaluated on the basis of variety of images and compared with other algorithms (Canny, Sobel, Roberts, and Morphological Segmentation). The results demonstrate that the algorithm proposed is both accurate and efficient. The data and performance measures such as completeness and correctness are calculated together with other parameters which are Peak Signal to Noise ratio, Normalized Cross Correlation, Structural Content and a statistical analysis of the comparison is presented.Â
Review on Architectures of Motion Estimation for Video Coding Standards
Authors: Rajabai C Prayline , S Sivanantham 
Published: April 2019

Various video coding standards like H.264 and H.265 are used for video compression and decompression. These coding standards use multiple modules to perform video compression. Motion Estimation (ME) is one of the critical blocks in the video codec which requires extensive computation. Hence it is computationally complex, it critically consumes a massive amount of time to process the video data. Motion Estimation is the process which improves the compression efficiency of these coding standards by determining the minimum distortion between the current frame and the reference frame. For the past two decades, various Motion Estimation algorithms are implemented in hardware and research is still going on for realizing an optimized hardware solution for this critical module. Efficient implementation of ME in hardware is essential for high-resolution video applications such as HDTV to increase the decoding throughput and to achieve high compression ratio. A review and analysis of various hardware architectures of ME used for H.264 and H.265 coding standards is presented in this paper.Â Â

Published: April 2019

The main objective of this article is to specify a nonlinear regression model, formulate the assumptions on them and aquire its linear pseudo model. A model may be considered a mathematical description of a physical, chemical or biological state or process. Many models used in applied mathematics and Mathematical statistics are nonlinear in nature one of the major topics in the literature of theoretical and applied mathematics is the estimation of parameters of nonlinear regression models. A perfect model may have to many parameters to be useful. Nonlinear regression models have been intensively studied in the last three decades. Junxiong Lin et.al [1] , in their paper, compared best â€“fit equations of linear and nonlinearÂ forms of two widely used kinetic models, namely pseudo-first order and pseudo=second-order equations. K. Vasanth kumar [2], in his paper, proposed five distinct models of second order pseudo expression and examined a comparative study between method of least squares for linear regression models and a trial and error nonlinear regression procedures of deriving pseudo second order rare kinetic parameters. Michael G.B. Blum et.al [3] proposed a new method which fits a nonlinear conditional heteroscedastic regression of the parameter on the summary statistics and then adaptively improves estimation using importance sampling.Â Â

Published: April 2019

In the era of Internet, user engagement has become more significant and relevant due to the intensification of interaction between the user and web applications. Today, most of the computer-based information systems that are in use to support our day-to-day activities are deployed on the web-based platform. The quality and intensity of interaction between the user and these web-based applications are referred as user engagement. While studies on user engagement have been quite extensively reported in the literature, very few have attempted to examine its relationship with user satisfaction. To this effect, this study was conducted with the aim of filling this research gap. The study used survey as the research methodology and the web, digital library as the object of assessment. 299 respondents provided the research data that were analyzed using Partial Least Square Structural Equation Modeling (PLS-SEM) approach. The results of the study showed that user engagement is a strong predictor of user satisfaction. The findings provide additional empirical evidence on the topic of user engagement.Â Â

Authors: E Hertzog Pierre , J Swart Arthur 
Published: April 2019

It is essential to repeat a test of a given construct in research in order to underpin knowledge, support validity and enable its application in other contexts. The purpose of this article is to present repetitive test results validating the optimum tilt angle of a stationary PV module that was installed in a semi-arid region of South Africa. An experimental design incorporating a two-year longitudinal study is used. The results for 2016 and 2017 reveal that a PV module with a tilt angle of Latitude plus 10Â° yielded the highest output power for winter months, while a PV module with a tilt angle of Latitude minus 10Â° yielded the highest output power for summer months. However, for both years, a tilt angle set to the Latitude angle of the installation site yielded the highest overall average output power (60.02 Wh per day). It is therefore recommended to install stationary PV modules at a tilt angle equal to the Latitude of the installation site for a semi-arid region in the southern hemisphere.Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â

Published: April 2019

The demand for multimedia services i.e. audio, video and data with improve QoS and optimum utilization of resources in WSNâ€™s has posed new challenges. As the intensity of traffic increases; it demands for higher bandwidth and dedicated resources to reduce packet loss and delay. There have been analytical models proposed where priorities were assigned to video and voice packets to reduce packet loss and optimize resource utilization. In this paper distributed scheme is proposed to handle video, voice and data packets by having multiple sink nodes. There are shared sink nodes where video, voice and data packets are serviced and dedicated sink nodes only for video and voice packets. The proposed scheme has shown that the packet loss for data packets is higher than voice and video packets. The simulation results show that the performance of the network is improved when priorities are assigned to video and voice packets by giving dedicated resources.Â Â

Published: April 2019

Water scarcity is one of the most important problems in Middle East and North Africa. Many researchers believe that solar distillation is the best solution to solve water scarcity, especially since these areas are characterized by abundant solar energy most days of the year. One of the main disadvantages of solar distillates is the low rate of production and therefore the research focuses on the factors that many enhance and improve the rates of production of the solar stills.Â In this paper, the performance of a passive built in condenser incorporated into a solar still is studied theoretically and experimentally using. A theoretical frameworkÂ is developed to forecast the productivity performance (accumulated and hourly), the temperatures of the various elements of the stills. The theoretical and experimental results were compared together and discussed thoroughly.Â Both theoretical and experimental results were in good agreement. The behaviors of both agree well with each other and have similar trends.Â

Published: April 2019

Pocket Code is an integrated development environment (IDE) targeted at smartphones. With this IDE users can create mobile apps for the block-based visual programming language Catrobat. Pocket Code is released in various flavors with custom features for partners and projects (e.g., Pocket Code, Create@School, Phiro, and Standalone). All flavors extend a single common project codebase according to flavor specific requirements. The Standalone variants (debug and release) convert a Catrobat project into an Android application to install it independently and execute it without the need for an installed Pocket Code on an Android smartphone. Furthermore, it can be published on app stores for reputational and also monetary benefits. The app resource files and the configuration are generated on the fly upon a user request via the Pocket Code sharing platform. In this paper, the approach of building a Pocket Code variant and transform a Pocket Code project into an Android application are described. Especially the Standalone build variants have the potential to bring many interesting apps to the market.Â Â

Published: April 2019

This research investigated the possibility of using plaster of Paris instead of cement in some internal structural parts and non-exposed to moisture by casting (nine) samples divided in three group. First group was normal concrete, second was plaster of pairs concrete group and finally plaster of Paris with aggregate concrete. All of them have the same dimension (1000Ã—150Ã—200) mm and the same reinforcement ratio. Group one was cured with water while the rest were isolated in a place far away from the moisture. All sample designed to be failed in flexural. The process of testing was divided in two methods; for properties of material used as explain above and for samples tested under two-point load at several curing time (7,28 and 90) days.Â Each period consists of three samples one from each group. The result showed that the third group (plaster of Paris with aggregate concrete) approximately closer to normal concrete in applying a load by the ratio of (98%) in 7 days, (87%) in 28 days and (94%) in 90 days. While the second group (plaster of pairs concrete) was acceptable when compared with normal concrete because of missing aggregate.Â Â
