Authors: Bharath S. , Nagesh P. , . .
Published: April 2019

The factors associated with branding were identified beneath communication/marketing remit.Â  There existed no difference between the employer brand and consumer brand.Â  Companies who had strong product/ service brand would de facto be attractive to potential employees. Today, companies require blended capabilities. Ultimately, it is the personal experience of the relationship that a person develops within an organization that determines the longevity and win-win consummation of association. An extended concept of relationship marketing principle is Employer branding. An endeavor has been made through this research with an objective to identify the Employer Branding Dimensions (EBD) in selected Information technology firms located in Bangalore from existing employee perspective. Study has been executed using structured questionnaire with Information Technology (IT) employees as respondents from various companies like, Infosys, IBM, NTT DATA, Marvell technologies, JDA software solutions. Data thus collected is analysed using software package and considering the factor loadings, key dimensions (factors) that constituted the Employer branding. The findings of the study emphasize that relationship among dimensions constituting individual employer branding highlights the complexity in its significance as no individual factor has dominant influence on Employer Branding.

Published: April 2019

In the context of modeling the propagation of mobile radio signals, optimizing the existing path loss model is largely required to precisely represent the actual propagation medium. In this paper, a hybrid tuning approach is proposed by merging the stochastic Weighted Least Square method and Genetic algorithm. The proposed hybrid optimization is employed to optimize the parameters of Cost 231 Hata propagation model and is validated by cellular field strength measurements at 900 MHz in the sub urban region. The hybrid optimization is compared with optimized results of Weighted Least Square method and Genetic algorithm. The least values of Mean Square error (0.2702), RMSE (0.4798) and percentage Relative error (3.96) justify the tuning precision of the hybrid method. The proposed optimization approach could be used by network service providers to improve the quality of service and in mobile radio network planning of 900 MHz band for 4G LTE services.Â Â

Road Extraction using Deep Learning
Authors: D. Dorathi Jayaseeli J. , Malathi D. , S Gopika
Published: April 2019

The Road extraction from aerial image, stands as a quintessential node for the development of rudimentary layers in innumerable fields. From GIS, to Unmanned Aerial vehicles, road maps pave the foundation for data accumulation. This significant process is a result of number of mechanisms devised over the years through iterative experiments and research.  However, the glut of methods available often pose as a hurdle in the selection process. In this project we implement a novel approach to solve the extraction problem, by incorporating generative algorithm using conditional adversarial networks. We investigate conditional adversarial networks as a general-purpose solution to image-to-image translation problems. These networks not only learn the mapping from input image to output image, but also learn a loss function to train this mapping. This makes it possible to apply the same generic approach to problems that traditionally would require very different loss formulations. The U-Network incorporated essentially convolves and de-convolves over the generative model, thus producing a pixel to pixel image translation, the result of which is the vector road map of its corresponding aerial image. The entire model is trained on a 990 MS GPU for computational ease.

Authors: Jadid Abdulkadir Said , Alhussian Hitham , Nazmi Muhammad , A Elsheikh Asim
Published: April 2019

Forecasting time-series data are imperative especially when planning is required through modelling using uncertain knowledge of future events. Recurrent neural network models have been applied in the industry and outperform standard artificial neural networks in forecasting, but fail in long term time-series forecasting due to the vanishing gradient problem. This study offers a robust solution that can be implemented for long-term forecasting using a special architecture of recurrent neural network known as Long Short Term Memory (LSTM) model to overcome the vanishing gradient problem. LSTM is specially designed to avoid the long-term dependency problem as their default behavior. Empirical analysis is performed using quantitative forecasting metrics and comparative model performance on the forecasted outputs. An evaluation analysis is performed to validate that the LSTM model provides better forecasted outputs on Standard & Poorâ€™s 500 Index (S&P 500) in terms of error metrics as compared to other forecasting models.Â Â

Published: April 2019

It is a known fact that Android mobile phonesâ€™ security has room for improvement. Many malicious app developers have targeted Â Â Â Â android mobile phones, mainly because android as an open operating system provides great flexibility to developers and there are many android phones which do not have the latest security updates. With the update of marshmallow in android, applications request Â Â Â Â Â Â Â Â Â Â permission only during runtime, but not all users have this update. This is important because user permission is required to perform Â Â Â certain actions. The permissions may be irrelevant to the features provided by an application. The purpose of this research is to Â Â Â Â Â Â Â Â Â investigate the use and security risk of seeming irrelevant permissions in applications available from Google store. Two different Â Â Â Â Â Â Â applications which seem to ask irrelevant permissions during installation were selected from Google store. To test these applications, static analysis, dynamic analysis and reverse engineering tools were used. Findings show potentially malicious behavior, demonstrating that downloading apps from Google play store do not guarantee security.Â Â

Published: April 2019

Rapid Quality assurance is an important element in software testing in order to produce high quality products in Software Product Line (SPL). One of the testing techniques that can enhance product quality is Model-Based Testing (MBT). Due to MBT effectiveness in terms of reuse and potential to be adapted, this technique has become an efficient approach that is capable to handle SPL requirements. In this paper, the authors present an approach to manage variability and requirements by using Feature Model (FM) and MBT. This paper focuses on modelling the integration towards enhancing product quality and reducing testing effort. Further, the authors considered coverage criteria, including pairwise coverage, all-state coverage, and all-transition coverage, in order to improve the quality of products. For modelling purposes, the authors constructed a mapping model based on variability in FM and behaviour from statecharts. The proposed approach was validated using mobile phone SPL case study.

Authors: Nawanira Gusman , Khai Loona Lee , Mahmuda Fatimah , Kong Teongb Lim
Published: April 2019

The journey towards sustainable development (SD) in Malaysia was started since the 1970s. Afterwards, a Malaysian New Economic Model (NEM) was formulated to pursue SD targeting high income, inclusivity and sustainability, which is in line with the 2030 SD agenda. Based on the goals of NEM, the Eleventh Malaysia Plan 2016-2020 (11MP) was developed. One of the 11MP coverage areas is education. In order to be sustainable, Malaysian higher-education institutions (HEIs) committed to corroborate this agenda by articulating an obligation to embrace the sustainability principles. However, within the Malaysian academic setting, it is still in its infancy, as most of the studies were constrained within the context of single university. In addition, to what extent the planning, strategies, and approaches for HEIs sustainability have been implemented tended to be neglected. Consequently, SD in HEIs is still far from being integrated into a holistic manner by policy makers. This paper extensively reviews the literature regarding the SD in the context of HEIs and provides some ideas for the future research leading towards the development of a comprehensive framework for sustainability development in Malaysian HEIs. Expectedly, this study could benefit policy makers, key players, and universities top management to progress towards sustainable university in an effective and efficient manner. It may strengthen the discourse on the implementation of SD initiatives within the Malaysian HEIs.Â Â

Millions of people need blood because of many reasons such as accidents, routine surgeries, treatment of serious diseases such as cancer and thalassemia. In many countries, the availability of blood product depends on a small number of volunteer donors, including Malaysia. Present trends in blood collection and capacity usage in Malaysia have raised concerns about the ability to meet potential needs. To ensure an adequate blood supply in health facilities is a challenging task for the government especially Ministry of Health Malaysia. It is important to develop a program with influential initiatives that can help to boost public interest and willingness to involve in blood donation program. This study aims to identify and examine the initiatives conducted by the government in order to attract the interest of public to become volunteer blood donor. This study identified that there were five main initiatives implemented by the government to attract public to donate blood, namely: (a) intensive advertising (via mainstream television and radio channels); (b) mobile blood transfusion service center; (c) incentives to blood donors; (d) establishments of donation suites, and; (e) collaboration with other government institution for blood donation campaign. Although current situation showed significant changes in terms of public awareness and willingness towards this program, but there are rooms for improvement for the government to consider in maintaining the balance between blood supply and demand in the country. Focusing on public to register, as frequent or repeated volunteer blood donor, is obviously one of the main available option that current situation need to strengthen.Â

The harmonic elimination of multilevel inverters is a complicated task that includes nonlinear transcendental equations. With the increase in the level of the multilevel inverter, the no of variables of the equation also increases which makes the problem more complicated. Metaheuristic optimization algorithms play an important role in finding out optimum switching angles required for elimination of harmonics in a lesser computational time avoiding multiple local minima. This paper deals with the harmonic elimination of cascaded multilevel inverter using whale optimization algorithm. The whale optimization method has the ability to escape local minima and it takes less time of computation of results. Results are verified theoretically by taking an example of a 15-level cascaded H-bridge inverter fed from equal d.c.sources. The above scheme well minimizes lower order harmonics and gives better output voltage and a low total harmonic distortion.Â Â

Published: April 2019

Considering the urban environment, we proposed a new model â€œParking Management Systemâ€. The complete model provides you the basic features of the parking system. The system designates an exact parking slot for the driver. On the basis of user requirement, it includes the proximity to destination and the cost of parking. The capacity of overall parking is utilized efficiently. The system approach solves the problem at individual decisions in a time driven sequence. This is the most favorable solution based on the allocation on present state affair and subject to the arbitrary incidents such as the request of the new user and availability of the parking space. At the next decision point, the allocation is updated ensuring that there is no conflicts in the resource reservation and the assignment of resource have the higher cost than the current cost of function value. The proposed system enables users to find out the free parking space on the cost on new performance metrics to calculate the cost of user parking under the consideration of distance and the total no of free places. The system show that the algorithm helps improves the probability of successful parking and the user waiting time is minimized. The proposed system is implemented by us in the real world successfully.Â Â
Serially Concatenated Low-density Parity Check Codes as Compatible Pairs

Published: April 2019

Low-density parity checks (LDPC) codes are considered good performance error correction codes. However, decoder complexity increases with increasing code length. In this study, we introduce short-length serially concatenated LDPC codes. The proposed technique uses pairs of compatible LDPC codes that act as outer and inner serially concatenated codes. In this code pair, the inner code takes input that is the same length as the outer LDPC encoder output. This study examined two cases of LDPC codes as compatible pairs with low numbers of iterations and compared bit error rate (BER) performance to a standalone LDPC code with an additive white Gaussian noise channel. We also considered the quadrature phase shift keying QPSK, 16-quadrature amplitude modulation (QAM), and 64-QAM system modulation schemes. Simulation results demonstrate that the proposed system has good BER performance compared to a standalone LDPC code, the results summarized in table and performance curves.Â Â Â
Flat sheet of Zinc material as a filter for gamma photons in Tc-99mm SPECT imaging
Authors: Abdullah Nazifah , Shah Syed Inayatullah , Zakaria Ahmad
Published: April 2019

Purpose of the Study: Scattered gamma photons in single photon emission computed tomography (SPECT) is one of the main issues that degrade the image quality. There are several types of scatter correction methods. However, none of the technique is applied in routine clinical Tc-99m SPECT imaging. Therefore, Zinc (Zn) material filter was constructed for pre-filtration of scattered gamma photons in Tc-99m single photon emission computed tomography (SPECT).Materials and Methods: Tc-99m radioactivity was administered into the Carlsonâ€™s phantom. Planar and tomographic data were acquired with and without hot regions insert, respectively, with and without material filter. Scatter to non-scatter ratio was measured from the photopeak region of Tc-99m spectra. Tomographic images were generated using filtered back projection method. Contours on images were drawn with ImageJ software. Images obtained with and without material filter were analysed in terms of detectability of hot regions.Results: Remarkable decrease (â‰ˆ 21%) in the ratio of scattered to non-scattered gamma photons with material filter was achieved. Detectability of smaller hot regions with material filter was enhanced. In terms of sizes of all hot regions, material filter results appear closer to the original sizes.Conclusion: Material filter technique could be applied in Tc-99m clinical SPECT, while organ phantom studies are needed.Â  Â Â

Published: April 2019

As from the year 2011 to date, the oil and gas exploration (O&G) industry in Indonesia is not attractive anymore to the investors. It is clearly shown by all indicators of the O&G exploration performance in Indonesia which decline sharply causing the RRR (Reserves Replacement Ratio) is currently about 0.5.Â  As the result the national O&G reserves and production decline as well. Starting the year 2004 Indonesia has become an oil nett impoter; the consumption is much bigger than the national production. This is threatening the availability of O&G energy source so that it can cause state instability. This study aims to conduct the assessment of the investorsâ€™ perspective on the investment attractivenesss of O&G exploration industry in Indonesia, taking into account two main variables, i.e: the Government Regulation and Global Environment Variables using Analytical Hierarchy Process (AHP) method. The units of analysis are the O&G investors which means the shareholders. Meanwhile, observation units are the top management and the managers of O&G companies in Indonesia. Result of the study shows that Government Regulation Variable is the worse variable to accommodate the investorsâ€™ expectation causing the low attractiveness of the O&G exploration industry in Indonesia. Surprisingly the influence of Global Environment variables, such as world crude oil price, is not significant compared to the Government Regulation. To increase the attractiveness of O&G exploration industry, Government of Indonesia should reform the existing regulation and increase government support for this industry to match the global environment which keeps changing.Â Â
