The growth in number and capacity of smart devices such as GPS enabled smart phones and PDAs present an unparalleled opportunity for diverse areas of life. In this paper we propose an approach for vehicle theft protection using GPS based trajectory anomaly detection. The detailed methodology of the proposed system is briefly described in this paper.
Effect of Peritectic Banded Structure on Magnetic Properties of SmCo<SUB>5</SUB> Sintered Magnets
Saleem Akhtar,A. Nusair Khan,Mushtaq Khan,Syed Husain Imran Jaffery,Arslan Saleem 한국자기학회 2020 Journal of Magnetics Vol.25 No.4
SmCo5 is well known for its high coercivity. However, still room is available to increase the coercive power of SmCo5, since the theoretical values of the compound is far higher than the achieved values. Different attempts, in this regard, have been made either by controlling the microstructure or the chemical composition. However, it is noted that no or very few literature is available regarding the control of microstructure through solidification. Three types of SmCo5 compound were prepared through induction melting technique so that final solidification be manipulated by controlling the mold temperature. Fractrographic analysis revealed a unique peritectic structure in SmCo5 compound. It was observed that the peritectic plates, having nano-size thickness, remain present even after high temperature sintering operation. The nano-scale peritectic plates may affect the final magnetic properties, especially the coercivity of the subject compound.

E-Commerce is a buzzword well known for electronic commerce activities including but not limited to the online shopping, digital payment transactions, and B2B online trading. In today's digital age, e-commerce has been playing a very important and vital role in areas such as retail shopping, sales automation, supply chain management, marketing and advertisement, and payment services. With a huge amount of data been collected from various e-commerce services available, there are multiple opportunities to use that data to analyze graphs and trends. Strategize profitable activities, and forecast future trade. This paper explains a contemporary approach for collecting key data metrics and implementing cost-effective automation that will support in improving conversion rates and sales performance of the e-commerce websites resulting in increased profitability.
High Quality Network and Device Aware Multimedia Content Delivery for Mobile Cloud
( Muhammad Saleem ),( Yasir Saleem ) 한국인터넷정보학회 2019 KSII Transactions on Internet and Information Syst Vol.13 No.10
The use of mobile devices is increasing in multimedia applications. The multimedia contents are delivered to mobile users over heterogeneous networks. Due to fluctuation in bandwidth and user mobility, the service providers are facing difficulties in providing Quality of Service (QoS) guaranteed delivery for multimedia applications. Multimedia applications depend on QoS parameters such as delay, bandwidth, and jitter to offer better user experience. The existing schemes use the single source and multisource delivery but are unable to balance between stream quality and network congestion for mobile users. We proposed a Quality Oriented Multimedia Content Delivery Scheme (QOMCDS) for the mobile cloud to deliver better quality multimedia contents for the mobile user. The multimedia contents are delivered to the mobile device based on the device’s parameters and network environment. The objective video quality assessment models like Peak Signal-to-Noise Ratio (PSNR), Structural Similarity (SSIM), and Video Quality Measurement (VQM) are used to measure the quality of the video. The client side Quality of Experience metric such as Startup delay, Rebuffering events, and Bitrate switch count was used for evaluation. The proposed scheme is evaluated using dash.js and is compared to existing schemes. The results show significant improvement over existing multimedia content delivery schemes.

This paper presents a robust-optimal control strategy to improve the output-voltage error-tracking and control capability of a DC-DC boost converter. The proposed strategy employs an optimized Fractional-order Proportional-Integral (FoPI) controller that serves to eliminate oscillations, overshoots, undershoots and steady-state fluctuations. In order to significantly improve the error convergence-rate during a transient response, the FoPI controller is augmented with a pre-stage nonlinear error-modulator. The modulator combines the variations in the error and error-derivative via the signed-distance method. Then it feeds the aggregated-signal to a smooth sigmoidal control surface constituting an optimized hyperbolic secant function. The error-derivative is evaluated by measuring the output-capacitor current in order to compensate the hysteresis effect rendered by the parasitic impedances. The resulting modulated-signal is fed to the FoPI controller. The fixed controller parameters are meta-heuristically selected via a Particle-Swarm-Optimization (PSO) algorithm. The proposed control scheme exhibits rapid transits with improved damping in its response which aids in efficiently rejecting external disturbances such as load-transients and input-fluctuations. The superior robustness and time-optimality of the proposed control strategy is validated via experimental results.

Women entrepreneurs play a vital role in employment creation, economic development, and growth. Women entrepreneurship is deep-rooted in the social and cultural norms and values of society. Women's entrepreneurship contribution is still invisible and needs to be properly investigated. The current research study explores "how institutions affect women's entrepreneurial performance in Pakistan" by using institutional and social cognitive theories. Focusing on the Formal and informal institutions, this research examines how institutions are affecting women's entrepreneurial performance by taking the mediating role of women's entrepreneurial self-efficacy and ethical decision making. A 7-point Likert scale research questionnaire is used to collect primary data. Data on active entrepreneurs are collected from the Peshawar, Mardan, and Abbottabad divisions of KPK's Women Chambers of Commerce. The data is empirically tested through the path analysis technique of structural equation modeling (SEM) through SMART PLS 3. The results indicated that women's entrepreneurial self-efficacy and ethical decision-making strongly mediate both institutions and significantly affect women's entrepreneurial performance. The study suggests that government and concerned departments should pay due attention to determinants like informal institutions and social constraints to boost women's entrepreneurial performance.
