Hashing based Hybrid Online Voting Using Amazon Web Services
Authors: S Murali , A Manimaran , K Selvakumar , Kumar S Dinesh
Published: April 2019

The secured web-based voting framework is the need of the present time. We propose another secure authentication for the online voting framework by utilizing face recognition and hashing algorithm. A simple verification process is accomplished during the initial registration process via email and phone. The voter is asked to give a unique identification number (UIN) provided by the election authority and face image at the time of main registration. This UIN is converted into a secret key using the SHA algorithm. The face image that is saved in the Amazon web service (AWS) acts as an authentication mechanism which enables people to cast their vote secretly. The voters, who cast numerous votes amid the way toward voting is guaranteed to be counteracted by encrypted UIN.Â  The election organizers can see the election parallelly as the voting is saved in the real-time database. The privacy of the voter is maintained as the details are converted into the key. In this system, an individual can vote from outside of his/her allocated constituency.Â Â

Authors: Avital EJ , Ai K , Venkatesan N , Samad A , Korakianitis T
Published: April 2019

The hydrodynamic performance of a dual-rotor horizontal axis marine turbine (HAMCT) is investigated for the power gain in operating the rear rotor without blade-pitch control. This kind of turbine can be advantageous for a rectilinear tidal current of reversing directions, where each rotor blade is optimally fixed-pitched towards its upstream velocity. The blade element momentum (BEM) method is coupled with the Park wake model. A generic three-blade turbine is shown to gain up to 20% in the coefficient of power CP as relative to the front rotor CP when operating the rear rotor at the same tip speed ratio (TSR) as the front one, gaining overall CP up to 0.55. Analytic model is derived to backup the estimate of power gain. Plots for turbine performance variation with TSR and profile hydrodynamic efficiency are given, and analysed for lab and small-medium size turbines.Â Â

Authors: Sreenadh S. , Sumalatha B. , N.S.Srinivas A.
Published: April 2019

In order to model the blood flow through an artery in presence of catheter, we considered a steady, laminar, incompressible, Poiseuille flow of a Herschel-Bulkley fluid between two horizontal parallel elastic walls. The power law index ( ) and yield stress ( ) are the two parameters of the Herschel - Bulkley fluid. By giving different values for the above mentioned parameters, we get the Newtonian, Bingham and Power-law fluids as special cases. The exact solutions for the flow quantities such as velocity, plug flow velocity and flux are derived. The flux is determined as a function of inlet, outlet, external pressures and the elastic property of the channel. The effect of elastic parameters on flux variation is analyzed. Further when and our results qualitatively agree with those of Rubinow and Keller [2]. In addition, velocity of the Herschel- Bulkley fluid flow is expressed in terms of elastic parameters.

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

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

Authors: ALIAS MASLINDA , HAMZAH SOFIAH , SAIDIN JASNIZAT
Published: April 2019

This present study focused on the extraction of HAp from fish scale waste using alkaline heat treatment sintered at different sintering tem-perature (high range) between 300° C to 1000°C. White powder hydroxyapatite was characterized in term of morphology, surface chemistry and crystallinity structure using Scanning Electron Microscopy, Fourier transform infrared spectroscopy (FTIR) and X-ray Diffraction (XRD), respectively. Analysis from XRD shows that FSHAp-1000 has good sharp peak indicating for high crystallinity of hydroxyapatite. While, the functional analysis performed FTIR determined several functional group attributed to PO42-, CO23- and OH-. As sintering tem-perature increase, the broad peak of PO42- becomes narrower. The intensity of CO32- is observed decreased at higher calcination temperature since they are release as volatile gases. Meanwhile, adsorbed water become narrower under treatment of water. The morphology of FSHAp changed upon treatment of heat especially at high temperature. As sintering temperature increase, the particle size of FSHAp becomes fines and a regular shape of FSHAp was found agglomerated.

There are many challenges for the digital forensic process in the cloud computing due to the distinguished features of the cloud computing environment. Many of well-known digital forensic methods and tools are not suitable for cloud computing environment. The multi-tenancy, multi-stakeholder, Internet-based, dynamics expendability, and massive data, logs and datasets are examples of the cloud computing environment features that make conducting digital forensics in the cloud computing environment a very difficult task. Therefore, there is a need to develop an appropriate digital forensic approach for cloud computing environment. Thus, this paper proposed a proactive digital forensic approach for cloud computing environment.Â

Recent trends in big data have shown that the amount of data continues to increase at an exponential rate. This trend has inspired many researchers over the past few years to explore new research direction of studies related to multiple areas in big data. Hadoop is one of the most popular platforms for big data, thus, Hadoop MapReduce is used to store data in Hadoop distributed file systems. While, cloud computing is considered an excellent candidate for storing and processing the big data. However, processing big data across multiple nodes is a challenging task. The problem is even more complex using virtualized clusters in a cloud computing to execute a large number of tasks. This paper provides a review and analysis of the impact of using physical versus cloud cluster in the processing a large amount of data. This analysis has an impact on the processing in terms of execution time and cost of using each one of them. The result indicates that the use of cloud virtual machines helped better utilize the resources of the host computer.Â

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

Keyword-based technique has low accuracy and always leads to wrong information retrieved. Therefore, many researchers implement semantic search to overcome the above problems. Many researchers have built different Quran ontology in various domains to facilitate the knowledge representation in the Quran. Nevertheless, there are many domain concepts mentioned in the Quran which are not yet covered, especially for the Medical and Health Science domain. Hence, this research presents the development of ontology for the Medical and Health Science domain in the Quran and implementation of ontology-based search method to answer related queries in the Quran. The development of ontology adopts the ontology 101 approach which later evaluated by Quran experts. Furthermore, a hybrid search tool was developed that encompassed semantic-based and keyword based technique to answer a user query. The search tool was evaluated using the Recall and Precision measurements, which shows high accuracy in retrieving the Medical and Health Science knowledge in the Quran. For future work, this research can be used as a reference and basis to answer user queries, data integration with other applications or existing ontology can be further expanded.

The growth of cyberspace world has uprising government agencies in a new way to serve citizen in a proactive, efficient and productive manner. To have an open, stable and vibrant cyberspace, governments should be more resilient to cyber-attacks and able to protect all government agency’s interest in cyberspace. Therefore, the government needs a transformative cyber governance security model to protect valuable government agencies’ information. The model should be able to detect, defend and deter the vulnerabilities, threats and risks that will emerge in the day to day government administration operation. This paper has introduced a study for some existing cyber governance security models. Thus, it helps in determining the main features of the required model.

Today’s contemporary business world has incorporated Web Services and Web Applications in its core of operating cycle nowadays and security plays a major role in the amalgamation of such services and applications with the business needs worldwide. OWASP (Open Web Application Security Project) states that the effectiveness of security mechanisms in a Web Application can be estimated by evaluating the degree of vulnerability against any of the nominated top ten vulnerabilities, nominated by the OWASP. This paper sheds light on a number of existing tools that can be used to test for the CSRF vulnerability. The main objective of the research is to identify the available solutions to prevent CSRF attacks. By analyzing the techniques employed in each of the solutions, the optimal tool can be identified. Tests against the exploitation of the vulnerabilities were conducted after implementing the solutions into the web application to check the efficacy of each of the solutions. The research also proposes a combined solution that integrates the passing of an unpredictable token through a hidden field and validating it on the server side with the passing of token through URL.

Today, one of the challenges of modern urbanization in Iran is the issue of old and worn-out urban textures and identification of their criteria. Samen District of Mashhad, a historical texture in an area of 321 hectares, was selected as the study sample. The aim of this study was to determine priorities of improving old neighborhoods based on criteria of weariness. The research adopted a descriptive-analytical method and used the model of Analytical Hierarchy Process (AHP) for the process analysis. The data collection was conducted by a questionnaire (according to Cochran’s formula, 287 questionnaires were randomly distributed in 6 neighborhoods using random sampling method), mapping and field study. Six parameters and twenty four indices were measured as criteria affecting the weariness process. Results showed that physical, constructional, environmental, economic, and social and services parameters had respectively the highest impact on worn-out urban texture. In addition, Eidgah, Payin Khiyaban, Tabarsi, Noghan, Bala Khiyaban and Chaharbagh were ranked first and sixth in terms of the degree of weariness and intervention priorities were specified in each neighborhood.

Military personnel are one of the occupations at high risk of developing low back pain (LBP) due to its job demands. Low back pain (LBP) is a major cause of morbidity and lost from work among military personnel. This narrative review was conducted to determine the risk factors of LBP in military personnel/recruits. Searches focusing on causal comparative and epidemiology studies using OVIDMedline, CINAHL, SPORTDiscus, PubMed, and Scopus databases from year January 1950 to April 2018. The Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines was used to select and synthesis of studies. The strongest personal risk factors identified were history of LBP (OR = 8.91, CI = 1.71 -46.5), female gender (OR: 6.59, CI 1.79 – 24.24), aerobic exercise involvement (OR = 4.39, CI 1.53- 12.57) and older age (OR 4.16). The strongest occupational risk factors identified were prolonged hours of flight per day (OR=11.3, CI 5.2 -24.8), driving in forward bending posture (OR = 3.63, CI 1.06 – 12.42), branch of services (Army; OR 2.74, CI 2.60-2.89 & Air Force; 1.98, CI 1.84 -2.14), Night training (OR = 1.8-2.0, CI 1.1 – 3.1) and whole-body vibration exposure (OR 1.94, CI 1.02 -3.69). The strongest psychosocial risk factors identified were worries (OR = 5.47, CI 1.70- 17.62), no support from others (OR = 4.0, CI 1.31 -12.34) high work stress (OR = 3.47, CI 1.31 – 12.34), depression (OR = 1.75, CI 1.08 -2.83), and psychological stress (OR 1.71). This review summarizes the personal, occupational and psychosocial risk factors associated with LBP among military personnel/ recruits. LBP risk factors differs based on the military branch of services and job scope. Primary LBP risk factor for Air Force pilots, helicopter pilots and military vehicle drivers LBP is sitting ergonomics. Primary LBP risk factor for army (i.e. combat infantry) identified are occupational physical exposure (military training, heavy lifting and carrying, patrol durations.) Further studies are required to verify if there is any interaction between personal, occupational, and psychosocial LBP risk factor categories among military personnel/recruits.
