A Comparative Study of Effective Supervised Learning Methods on Arabic Text Classification

Summary Nowadays, Arabic Text Classification (ATC) is attracting researchers’ attention in many fields, including text mining, web search, social media, security, and other fields. Text Classification or Categorization (TC) is the process of classifying text documents to proper categories based on their contents. Few studies have been developed for the comparison of supervised learning (SL) methods on ATC. Consequently, this paper is concerned with ATC of Arabic documents. The proposed approach adopted for this comparative study consists of three steps: (i) document pre-processing step where Arabic stop words, punctuations, diacritics, common prefix and suffix (Arabic words light stemmer) are removed from the Arabic documents, (ii) document filtering step where the words strings are converted into number of individual words vectors using term frequency transform (TFT) technique, inverse document frequency transform (IDFT) technique and both, (iii) classification step where a comparison of eight effective known SL methods is adopted for ATC. The impact of using TFT, IDFT and both on the effectiveness of these SL methods is also studied. The results show that the accuracy of 10-fold cross validation test mode obtained by LSVM classifier with IDFT technique is the highest compared to other SL methods used in this study. This outcome can be used in the future as a guidance for developers of ATC applications.
Bi-Level Non-Linear Fractional Programming Problem with Random Fuzzy Parameters

Abstract: This paper presents a new random fuzzy bi-level non-linear fractional (RF-BLNLF) programming problem where the parameters of the right-hand side of the constraints in both first level and second level follows Cauchy distribution involving two parameters. The coefficients of the objective functions and constraints respectively are assumed to be trapezoidal and triangular fuzzy numbers. Mellin transformation is used to remove the randomness and fuzziness of the random fuzzy bi-level non-linear fractional programming problem and then it is transformed into equivalent deterministic-crisp problem. Also, an algorithm is introduced to find the best optimal solution by using fuzzy tolerance approach. Finally a numerical example is presented to illustrate the new method.
Binarized Revocable Biometrics in Face Verification

A two-factor revocable authentication approach, combining user-specific pseudo-random bit sequence with biometrics is presented. Through the mixing process, a distinct binary code, coined as BioBit, is formed. This provides a protection layer against biometrics fabrication because the system can cancel the compromised and reacquire a new one via bits replacement. BioBit delivers lower error rate as compared to sole biometrics when the genuine token is used by the authorized user. There are two identity theft scenarios may be raised: 1. stolen-biometrics: an imposter possesses intercepted biometrics data to be considered genuine; 2.stolen-token: an imposter has access genuine token and used it to claim himself as the genuine user. BioBit scheme shows the impressive performance (EER=0.001% and EER=0.002% tested on ORL and FERET datasets) in case 1. For thestolen-token case, this approach attains EER=1.28% and EER=1.36% on ORL and FERET datasets.

A Study of SEPIC Converter Based Fuzzy Logic Controller For Hybrid System

Renewable energy sources have attracted wide attention because of its abundant nature. Wind power can be easily captured by generators with high capacity. It is one of the promising and clean energy sources. Photovoltaic (PV) power is global and it can be extracted without using rotational generators. PV power is also another clean energy resource. PV and wind power are complementary in nature. During sunny days the winds will be weak and strong winds blow during nights and cloudy days. Hence, to get an uninterrupted supply wind-PV hybrid power generation system [1] [2] can be implemented. It provides higher reliability and continuous supply of power from any one of the resources either solar or wind. The wind energy conversion system consists of wind turbine and PMSG. WECS converts the mechanical energy into electrical energy. Wind turbine gives mechanical output which is converted into electrical energy by permanent magnet synchronous (PMSG) generator. It is a directly driven generator. It does not require any dc field excitation. The ac output from WECS is converted into dc by three phase diode rectifier. This paper uses a current-source-interface multiple input cuk converter [4] for integration of PV and wind resources. The MI cuk converter reduces unnecessary redundancy of additional parallel converters in each input source. The MI cuk converter is a DC-DC converter [14]. It provides decentralized control. It has two switches. Since the wind speed is constant, the duty cycle of one of the switches of the converter corresponding to PV input is controlled by fuzzy logic controller [19]. The inputs to the fuzzy logic controller are provided Maximum power point tracking algorithm (MPPT). The output voltage of VSI is regulated by PI controller. The gating pulses to VSI are generated by the PI controller. A Study of SEPIC Converter Based Fuzzy Logic Controller For Hybrid System

Conjugated linoleic acid (CLA) collectively refers to a group of positional and geometric isomers of linoleic acid with conjugated double bond structure arranged in different combinations of cis and trans configuration. Importance of CLA in the diets of humans as a vital health promoter has accomplished significance recently. It is present in many foods, especially high in milk and meat of ruminants, has numerous health benefits. Beneficial effects of CLA includes anticarcinogenic, anti-atherogenic, anti-obesity, anti-diabetic, immune system enhancement and few of detrimental affects includes gastrointestinal disorders, insulin resistance and gallstone formation which are isomer specific. Inspite of numerous health benefits associated with CLA, their mechanism of action still remains controversial. So, it is important to understand how different isomers of CLA functioning in the body acts to develop CLA enriched functional foods of animal origin. The objective of this review is to provide an overview regarding factors affecting CLA composition, its synthesis in ruminants and its impacts on human health.
DESIGN AND IMPLEMENTATION OF A MULTI-LAYERED SECURITY FOR CLOUD DATA CONSISTENCY AND INTEGRITY

: Consistency is an essential feature required by cloud computing. As cloud computing emerged as a new computing model in pay as you use fashion, individuals and organizations are storing their data in cloud. The storage service is known as Infrastructure as a Service (IaaS). Cloud also has other services known as Software as a Service (SaaS) and Platform as a Service (PaaS). When outsourced data is not consistent and the data integrity is lost, it indicates that the original data stored has been tampered with. This might happen due to hardware or software issues, VIRUS, malware or internal or external adversaries. Though cloud is providing plethora of benefits the consistency problem is potential risk to data owners. The consistency problem in cloud may occur due to replicas maintained in many servers. This is a challenging problem to be addressed. Based on the existing solution provided by Liu et al., in this paper we design and implement a multi-layered security for cloud data integrity. The proposed system takes care of various violations of data integrity with corrective measures. We built a prototype application that demonstrates the proof of concept. The empirical results are encouraging.
Strengthen Data Concealing Volume Utilizing LSB Based

Steganography is a main part of fast developing area of concealing information. Different applications have different requirements of Steganography methods. Most important properties of digital information is that it is easiest to produce and distribute unlimited numbers of its copies. This might undermine the music, Films, Books, and Software Industries. These bring variety of problems concerning protection of intellectual and production rights that badly required solving. Goal of Steganography is to conceal a message in one to one communications. For different image file formats different Steganographic algorithm exists. However in this paper two methods are discussed IMAGE DOMAIN and TRANSFORM DOMAIN. The use of LSB algorithm for image domain reduces the MSE (Mean square error) and improves PSNR (Peak signal to noise ratio) and BER (bit error rate) values, when there is addition of bit substitution. This work is simulated on MATLAB AND RESULTS SHOWS EFFECTS OF VARIOUS MESSAGE BITS FOR CONCEAL BITS. The transform domain conceals secret information in transform space lie in frequency domain.

Effective Elastic Property Estimation for Bi-continuous Heterogeneous Solids

In the present study we performed finite element simulation for bi-continuous heterogeneous solids via a random distribution of materials to predict effective elastic properties. With a random distributing scheme, a statistical analysis via finite element becomes feasible for the multiphase heterogeneous solids. Using a two-phase bi-continuous material as example, the numerical prediction of the effective properties is obtained in terms of a mean value and standard deviation with a sample size of 30 for each of given volume fraction. The finite element simulation results fall within the analytical bounds proposed by Hashin and Shtrikman (1963) based on the principle of variation. Comparison between the effective modulus based on the present bio-continuous morphology with the matrix-fiber configuration shows big difference. Keyword: Finite element analysis, effective modulus, bi-continuous solids, statistics.
Prevalence of Scardovia wiggsiae among a Pediatric Orthodontic Patient Population

Orthodontic treatment has been associated with changes in oral microbial flora, particularly among pediatric populations. Many studies have focused on the alterations in the prevalence of cariogenic pathogens, such as Streptococcus mutans. Recent evidence has revealed a newly discovered Gram-positive cariogenic pathogen, Scardovia wiggsiae – although few studies exist that explore prevalence among Orthodontic patients. Based upon this information, the primary objective of this study is to determine the prevalence of S. wiggsiae among pediatric Orthodontic patients from an existing saliva repository. This retrospective screening of the existing saliva sample repository revealed n = 156 pediatric (< 18) samples taken from the Orthodontic clinic that were not previously screened for the presence of S. wiggsiae. DNA isolation was performed on n = 107 samples and successfully isolated from n = 72 samples, yielding a recovery rate of 67.2%. Following DNA isolation, samples with sufficient quality and quantity were screened using qPCR with primers specific for S. wiggsiae. This analysis revealed the presence of Scardovia in n = 32/72 or 44.4% of successfully screened pediatric Orthodontic patient samples, which were almost evenly distributed among Males and Females. Although few previous studies exist to evaluate the prevalence of Scardovia, a previous study from this group demonstrated prevalence among pediatric patients of 26% and adult patients of 19%. Past studies also revealed the prevalence of S. wiggsiae in adult Orthodontic patients to be 14%. The data from this current study suggest significantly higher prevalence among pediatric Orthodontic patients, which provides new information regarding the potential changes in pathogen levels among this population. Although inference from this study is limited by the retrospective nature of this study, it may be among the first to report significant differences in S. wiggsiae prevalence among pediatric Orthodontic patients that may improve our understanding of cariogenic pathogens and risk among this population.
IJESRT INTERNATIONAL JOURNAL OF ENGINEERING SCIENCES & RESEARCH TECHNOLOGY Reversible Logic Based Arithmetic and Logic Unit

Reversible logic has received great attention in the recent years due to its ability to reduce the power dissipation which is the main requirement in low power digital design. It has wide applications in advanced computing, low power CMOS design, Optical information processing, DNA computing, bio information, quantum computation and nanotechnology. Conventional digital circuits dissipate a significant amount of energy because bits of information are erased during the logic operations. Thus, if logic gates are designed such that the information bits are not destroyed, the power consumption can be reduced dramatically. The information bits are not lost in case of a reversible computation. This has led to the development of reversible gates. ALU is a fundamental building block of a central processing unit (CPU) in any computing system; reversible arithmetic unit has a high power optimization on the offer. By using suitable control logic to one of the input variables of parallel adder, various arithmetic operations can be realized. In this paper, ALU based on a Reversible low power control unit for arithmetic & logic operations is proposed. In our design, the full Adders are realized using synthesizable, low quantum cost, low garbage output DPeres gates. This paper presents a novel design of Arithmetic & Logical Unit using Reversible control unit. These Reversible ALU has been modeled and verified using Verilog and Quartus II 5.0 simulator. Comparative results are presented in terms of number of gates, number of garbage outputs, number of constant inputs and Quantum cost.
