Research ArticleOpen accessIn the abstractHeavy Metals Content of the Grassland Soil around Katima Mulilo Municipal Solid Wastes Dumpsite, NamibiaJ. Abah, P. Mashebe, S.A. OnjefuThe effects of open wastes dumpsites on the immediate vicinity continue to generate safety concern. This study determined the levels of lead, chromium, cadmium, arsenic, nickel, cobalt, copper and manganese in soil samples collected at two depths: 0-15 and 15-30 cm within and around Katima Mulilo municipal solid wastes dumpsite and a control site. The samples were digested according to … …American Journal of Environmental Sciences, Vol. 13, Issue 2 · 18 Mar 2017 · 7,485 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Methodology for Continuous Evaluation of Cloud ResiliencyXiaoyong Yuan, Long Wang, Tiancheng Liu, Yue ZhangWith the growth of cloud computing, resiliency of cloud is critical for enterprises’ business. However, the continuous-changing of cloud makes evaluation of cloud resiliency more difficult. In this study, we design a methodology for automatic and continuous evaluation of cloud resiliency and implement it in a tool called CRGauge. The Continuous Evaluation Model methodology leverages fault injection techniques to inject … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 16 Mar 2016 · 7,840 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Study of the Quality Assessment Tools Based on a Model: Sonar, Squale, EvalMetricsZineb Bougroun, Adil Zeearaoui, Toumi BouchentoufTo build software, the customer is looking for a company that develops the product in record time with minimal cost and good quality. To measure the productivity and the software quality, several indicators and metrics have emerged, which have been the subject of various research fields and which are highly demanded by enterprises and software development teams. In order to … …Journal of Computer Science, Vol. 12, Issue 1 · 11 Mar 2016 · 6,989 accessesView PDFCite
Research NotesOpen accessIn the abstractA Proposed Framework for Outsourcing and Secure Encrypted Data on OpenStack Object Storage (Swift)Hala Albaroodi, Selvakumar Manickam, Mohammed AnbarDespite the numerous potential benefits of Open Source Cloud Computing (OSCC) in several industrial and academic-oriented environments, OSCC could be also associated with some risks. However, which a proper awareness to the cloud consumers or organisations, these risks can be clearly identify and avoided. OpenStack Swift security can provide a greater understanding of how OpenStack Swift functions and what types … …Journal of Computer Science, Vol. 11, Issue 3 · 14 May 2015 · 7,008 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalytical Analysis of In-Band Crosstalk, Out-of-Band Crosstalk and GVD-Based Power Penalties in DWDM and TDM/DWDM-PONSIbrahim Mohamed, Mohammad Syuhaimi Ab-RahmanIn addition to the ever-increasing demand for broader bandwidth per user, which results from the continuous development of new bandwidth-hungry services and applications, the consequent upgrade from the currently deployed Time-Division Multiplexing Passive Optical Networks (TDM-PONs) to Next-Generation Optical Access Networks (NG-OANs) has become inevitable. Different architectures for creating a NG-OAN have been proposed in the literature. Among those architectures, … …Journal of Computer Science, Vol. 11, Issue 3 · 13 May 2015 · 7,322 accessesView PDFCite
Research ArticleOpen accessIn the abstractExact Permutation Algorithm for Paired Observations: A General and Efficient VersionDavid T. MorseFor the better part of a century, methods have been illustrated for the enumeration of all possible permutations of cases from which an exact characterization of the likelihood of obtaining results as or more extreme as that observed may be determined without having to rely on parametric assumptions or schemes that may be only asymptotically correct. The challenge is the … …Journal of Mathematics and Statistics, Vol. 10, Issue 4 · 5 Jan 2015 · 6,677 accessesView PDFCite
Research ArticleOpen accessIn the abstractMethodology to Asses Internet Protocol Connection Availability: A Prerequisite For Feasible Video Stream Through Content Delivery NetworksVitor Chaves de Oliveira, Gunnar Bedicks Junior, Cristiano AkamineRecent events have shown that content delivery networks as well as Broadband Providers are failing to provide a continuous service, especially on live video stream transmissions for numerous customers. This study aims to present a Methodology to uninterruptedly measure uplink-downlink of a given IP connection. Based on an open-source assemblage of development and data storage platforms it was programmed a … …Journal of Computer Science, Vol. 11, Issue 2 · 2 Oct 2014 · 6,760 accessesView PDFCite
Research ArticleOpen accessIn the abstractINTRUSION DETECTION IN MOBILE AD HOC NETWORK USING SECURE ROUTING FOR ATTACKER IDENTIFICATION PROTOCOLS. Gopalakrishnan, P. GaneshkumarIn past few decades, the migration of communication takes place from wired networks to wireless networks because of its mobility and scalability and Mobile Ad hoc Network (MANET) is a unique and significant application in recent years which does not necessitates any pre-existing network infrastructure. Each node can act as both transmitters as well as receivers that are communicating with … …American Journal of Applied Sciences, Vol. 11, Issue 8 · 29 May 2014 · 6,722 accessesView PDFCite
Research ArticleOpen accessIn the abstractAN EVENT DRIVEN SIMULATION FOR ADAPTIVE GENTLE RANDOM EARLY DETECTION (AGRED) ALGORITHMOmid Seifaddini, Azizol Abdullah, Shamala SubramaniamSimulations are used to find optimum answers for problems in wide areas. Active queue management algorithms such as RED, GRED, typically use simulators like ns2 which is an open source simulator or OPNET, OMNET which are commercial simulators. However, beside the benefits of using simulators like having defined modules, parameters. There are problems such as complexity, large integrated components and … …Journal of Computer Science, Vol. 10, Issue 10 · 13 May 2014 · 7,011 accessesView PDFCite
Research ArticleOpen accessIn the abstractA REVIEW ON SECURED CLOUD COMPUTING ENVIRONMENTM. Hemanth Chakravarthy, E. KannanNowadays, the scientific problem becomes very complex; therefore, it requires more computing power and storage space. These requirements are very common in an organization while dealing with current technological data and requirements. Based on these basic requirements, need of higher computational resources is an important issue when dealing with current technological methodology. Hence, cloud computing has become the most important … …American Journal of Applied Sciences, Vol. 11, Issue 8 · 6 May 2014 · 6,583 accessesView PDFCite
