Review ArticleOpen accessIn the abstractState-of-the-Art in Techniques of Text Digital Watermarking: Challenges and LimitationsNasr Addin Ahmed Salem Al-Maweri, Roslizah Ali, Wan Azizun Wan Adnan et al.Data protection from malicious attacks and misuse has become a crucial issue. Various types of data, including images, videos, audio and text documents, have given cause for the development of different methods for their protection. Cryptography, digital signatures and steganography are the most well known technologies used to protect data. During the last decade, digital watermarking technology has also been … …Journal of Computer Science, Vol. 12, Issue 2 · 19 Mar 2016 · 8,526 accessesView PDFCite
Research ArticleOpen accessIn the abstractDegradation of Power Generation Performance due to Effects of Various Ice Shapes and Accretions on Wind Turbine BladesAditya Bagade, Changki Mo, Abdelhamid MazherIn today’s world, green energy has become a key initiative as an alternative energy resource. Wind turbines are widely used to harvest wind energy in seasonal and cold environments. Although efficient, cold weather conditions negatively affects wind turbine operations due to ice formation. Damage from icing is seen on blade-tips when super-cooled water droplets that form in colder environments rapidly … …Energy Research Journal, Vol. 6, Issue 2 · 11 Sep 2015 · 7,815 accessesView PDFCite
Research ArticleOpen accessIn the abstractGRID-IMAGE PASSWORD BASED SCHEME: ENHANCING MEMORABILITY FEATURES OF PASSWORDSObasan Adebola, Norafida Ithnin, Mohd Zalisham JaliPassword authentication has become a widely recognized element of computer security practices where human users are proven or confirmed as legitimate users for access to secure systems. Using this system, every user needs to recall its password correctly before access can be granted to an intended services or applications. Remembering the secure passwords is an everyday problem for users because … …American Journal of Applied Sciences, Vol. 11, Issue 7 · 9 Sep 2014 · 6,673 accessesView PDFCite
Research ArticleOpen accessIn the abstractMAPREDUCE CHALLENGES ON PERVASIVE GRIDSL. A. Steffenel, O. Flauzac, A. S. Charao et al.This study presents the advances on designing and implementing scalable techniques to support the development and execution of MapReduce application in pervasive distributed computing infrastructures, in the context of the PER-MARE project. A pervasive framework for MapReduce applications is very useful in practice, especially in those scientific, enterprises and educational centers which have many unused or underused computing resources, which … …Journal of Computer Science, Vol. 10, Issue 11 · 24 Jul 2014 · 9,834 accessesView PDFCite
Research ArticleOpen accessIn the abstractDEVELOPMENT OF OBSTACLE AVOIDANCE TECHNIQUE IN WEB-BASED GEOGRAPHIC INFORMATION SYSTEM FOR TRAFFIC MANAGEMENT USING OPEN SOURCE SOFTWARENik Mohd Ramli Nik Yusoff, Helmi Zulhaidi Mohd Shafri, Ratnasamy Muniandy, Islam Mohammad WaliThe shortest path routing is one of the well-known network analysis techniques implemented in road management systems. Pg Routing as an extension of Postgre SQL/Post GIS database is an open source library that implements the Dijkstra shortest path algorithm. However, the functionality to avoid obstacles in that analysis is still limited. Therefore, this study was conducted to enable obstacle avoidance … …Journal of Computer Science, Vol. 10, Issue 7 · 16 Jun 2014 · 6,931 accessesView PDFCite
Research ArticleOpen accessIn the abstractLIPASE-CATALYZED TRANSESTERIFICATION OF PALM KERNEL OIL WITH DIALKYLCARBONATESTjahjono Herawan, M. Rüsch Gen. KlaasLipase-catalyzed transesterifications-especially in a solvent-free medium-are important for industrial applications because such systems would have an enormous advantage by avoiding the problem of separation, toxicity and flammability of organic solvents. However, the organic solvent-free alcoholysis, especially methanolysis, does not give high conversions. The same problem also occurs when ethyl or methyl acetate are used as acyl acceptors. The main problems … …American Journal of Applied Sciences, Vol. 11, Issue 8 · 6 May 2014 · 6,793 accessesView PDFCite
Research ArticleOpen accessIn the abstractBAYESIAN MODEL AVERAGING WITH MARKOV CHAIN MONTE CARLO FOR CALIBRATING TEMPERATURE FORECAST FROM COMBINATION OF TIME SERIES MODELSHeri Kuswanto, Mega Rahmatia SariGlobal warming is an important issue related to the climate and weather forecast. It is shown by significantly increasing the atmospheric temperature level. Hence, improving the forecast accuracy of temperature is an important issue. The forecast is commonly done by performing a deterministic forecast meaning that the system will generate a point forecast without taking into account the uncertainty induced … …Journal of Mathematics and Statistics, Vol. 9, Issue 4 · 29 Nov 2013 · 7,078 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction of Recombinant Proteins in Insect CellsChristian Kollewe, Andreas VilcinskasAmong the wide range of methods and expression hosts available for the heterologous production of recombinant proteins, insect cells are ideal for the production of complex proteins requiring extensive post-translational modification. This review article provides an overview of the available insect-cell expression systems and their properties, focusing on the widely-used Baculovirus Expression Vector System (BEVS). We discuss the different strategies … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 3 · 21 Sep 2013 · 13,742 accessesView PDFCite

Research ArticleOpen accessIn the abstractIMPROVING DATA AVAILABILITY IN MOBILE ENVIRONMENT USING DATA ALLOCATIONMoaiad Ahmad Khder, Zulaiha Ali Othman, Abdullah Mohd Zin, Salha AbdullahData distribution is one of the crucial issues in Data Base Management Systems (DBMS) in general and in Mobile environment in Particular. It is important because, if not properly managed, it will cause reduction in data availability, which in turn causes more rejections in transactions. Replication algorithms (e.g., CCM) are used to improve data availability. However, the database replication algorithms … …Journal of Computer Science, Vol. 9, Issue 8 · 5 Jul 2013 · 6,860 accessesView PDFCite
