Assessments of lake profiling on temperature, Total Suspended Solid (TSS) and turbidity in the Kenyir Lake, Terengganu, Malaysia

Spatial interpolation method of water quality evaluation are frequently used to estimate valuation Kenyir Lake profiling used regression analysis and Geographic Information System (GIS) to assess a few of the water quality classification at Kenyir Lake. The purpose is to investigate the relative performance of different interpolation methods in surface waters. The study archived data from the Kenyir Lake using spatial interpolation of inverse distance weighting (IDW), which incorporates output from a process-based regression model.Interpolation were performed on temperature, total suspended solid (TSS) and turbidity (TUR) based on in-situ and ex-situ analyses according to the correlation matrix and linear regression at 14 different depths for the Chomor River and Mahadir Island. The result showed outlet significantly decreased over depth caused the water quality deterioration of Kenyir Lake development.Keywords: lake profiling; inverse distance weighting; total suspended solid (TSS); Interpolation; geographic information system (GIS

Implementing lightweight reservation protocol for mobile network using hybrid schema

This paper presents our method to improve lightweight reservation protocol. This was inspired by the ever increasing volume of multimedia traffic over the Internet which demanding quality of service beyond the traditional best-effort. The Integrated Services model relies on the Resource reservation Protocol (RSVP) for signaling and reserving resources. RSVP uses the receiver-initiated reservation mechanism to set up the reservation which executes protocol complexity and incurs additional processing and storage overheads on the routers. Due to heavyweight characteristic, many researchers changed the focus to the lightweight reservation protocol. In this paper, we propose a lightweight signaling protocol of Sender-initiated and Mobility-support Reservation Protocol (SMRP) with Crossover Router (COR) as an extension to SMRP. COR scheme cannot provide smooth handover as it affects the SMRP in Mobile hosts. This is the main disadvantage of COR scheme. Pointer Forwarding Scheme makes an advance resource reservation only a forwarding one-step path from the sender along the forwarding chains. In order to make SMRP more suitable for Mobile hosts, we propose a hybrid method combining the advantages of COR scheme with Pointer Forwarding scenarios. We use ns2 Java version network simulator to test it. We evaluate the performance of SMRP in a mobile network environment. The results show that the hybrid scheme can support seamless and also efficient SMRP path rerouting during handoff in respect of decreased the drop probability

Pixel value differencing steganography techniques: Analysis and open challenge

Steganography is the science of secret data communication using carrier medium, such as images, videos, text, and networks. Image steganography is majorly divided into spatial and frequency domains. Pixel value differencing (PVD) considered as good steganographic algorithm due to its high payload and good visual perception in spatial domain. The purpose of this paper is two folded. First is the critical analysis of current PVD methods using evaluating parameters (payload, visual quality and resistance of attacks) and secondly it highlights the current promising directions on PVD steganographic research

Partitioning the Heritability of Tourette Syndrome and Obsessive Compulsive Disorder Reveals Differences in Genetic Architecture

The direct estimation of heritability from genome-wide common variant data as implemented in the program Genome-wide Complex Trait Analysis (GCTA) has provided a means to quantify heritability attributable to all interrogated variants. We have quantified the variance in liability to disease explained

Building online historical resources collaboratively: making the most of a digital library to reinforce ICT skills in Malaysia

Presents a framework for a Collaborative Resource Development (CoreDev) digital library for Malaysian historical resources based on the development of local historical digital content by collaborating partners. The environment would provide the platform for the educational community to participate in e-publishing of resources that can be shared by others. The desired outcomes would be an enriched local content of historical resources on the Internet and ICT-literate teachers and students. The prototype uses a biographical portal as the test bed, incorporating five main modules: (a) off site creation, indexing, searching and retrieval of historical resources; (b) a database that supports multi-format digital resources; (c) simple and complex searches; (d) varied resource display; and (e) basic security features for participating partners. CoreDev is ideal for introducing the use of ICT as a research tool. Teachers can also use it extensively to teach Internet searching skills and make the most of its flexibility to reinforce basic ICT skills

Multi-bandwidth data path design for 5G wireless mobile internets

The 5th generation is envisaged to be a complete network for wireless mobile internet, which has the capability to offer services for accommodating the application potential requirements without suffering the quality. The ultimate goal of 5G is to design a real wireless world, that is free from obstacles of the earlier generations. This requires an integration of networks. In this paper, we propose the design of Multi-Bandwidth Data Path by integrating the current and future networks for new network architecture of 5G real wireless world. We also present our proposed architecture and results of the simulation

Source camera identification: a distributed computing approach using Hadoop

The widespread use of digital images has led to a new challenge in digital image forensics. These images can be used in court as evidence of criminal cases. However, digital images are easily manipulated which brings up the need of a method to verify the authenticity of the image. One of the methods is by identifying the source camera. In spite of that, it takes a large amount of time to be completed by using traditional desktop computers. To tackle the problem, we aim to increase the performance of the process by implementing it in a distributed computing environment. We evaluate the camera identification process using conditional probability features and Apache Hadoop. The evaluation process used 6000 images from six different mobile phones of the different models and classified them using Apache Mahout, a scalable machine learning tool which runs on Hadoop. We ran the source camera identification process in a cluster of up to 19 computing nodes. The experimental results demonstrate exponential decrease in processing times and slight decrease in accuracies as the processes are distributed across the cluster. Our prediction accuracies are recorded between 85 to 95% across varying number of mappers
