Research ArticleOpen accessIn the author namesAssessing of Soil Compaction and Relations to Soil Fertility on Different Land Used in Bintulu, SarawakAizul Azfar Zulkeefli, Md. Suzauddula, Md. Rezaul Karim et al.Assessing land uses-induced changes in soil properties from natural forests to farmland are indispensable for addressing the complications in terms of agricultural landscape sustainability. A study was conducted in Rehabilitated Forest (RF), Oil Palm (OP), Secondary Forest (SF) and Rubber Plantation (RP) at University Putra Malaysia in order to examine the results of soil densification on soil characteristics and fertility … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 11 Jan 2021 · 7,428 accessesView PDF Cite

Research ArticleOpen accessIn the author namesComparative Study of Packet Scheduling Algorithm in LTE NetworkAlaa Omer Najim, Nor Asilah Wati Abdul Hamid, Zurina Mohd Hanapi, Idawaty AhmadAt present, Long-Term Evolution (LTE) is the most popular Internet access technology because of its robust wireless connectivity that can support data, voice, video and messaging traffic. This advantage has significantly increased the number of users availing themselves of these services through various devices. Such an increase in the number of users has also increased network traffic. Thus, scheduling algorithms … …Journal of Computer Science, Vol. 13, Issue 12 · 20 Dec 2017 · 7,822 accessesView PDF Cite

Research ArticleOpen accessIn the author namesProposed Soil Quality Index for Rehabilitated Tropical Forest Sites in MalaysiaDaljit Singh Karam, Arifin Abdu, Keeren Sundara Rajoo et al.A proposed soil quality index named Tropical Soil Quality Index 2 (TSQI2) was developed in this study using statistical analysed data of selected properties (physical, chemical and biological) of composite soil samples collected from natural, secondary and rehabilitated forests of Chikus and Tapah Hill Forest Reserves, Perak, Malaysia. Results of soil evaluation using TSQI2 showed higher values for planted forest … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 30 Dec 2016 · 8,154 accessesView PDF Cite

Research ArticleOpen accessIn the author namesComparison of Classification Techniques on Fused Optical and SAR Images for Shoreline Extraction: A Case Study at Northeast Coast of Peninsular MalaysiaSyaifulnizam Abd Manaf, Norwati Mustapha, Md Nasir Sulaiman et al.Shoreline is a very important element to identify exact boundary at the coastal areas of a country. However, in order to identify land-water boundary for a large region using traditional ground survey technique is very time consuming. Alternatively, shoreline can be extracted by using satellite images that minimizes the mapping errors. The trend of extracting shoreline has been shifted from … …Journal of Computer Science, Vol. 12, Issue 8 · 27 Oct 2016 · 7,708 accessesView PDF Cite

Review ArticleOpen accessIn the author namesArchitecture of an Ultra-Low-Power Fully Autonomous Universal Power Conditioner of Energy Harvester for Wireless Sensor Networks: A ReviewYeo Kim Heng, Md. Shabiul Islam, Susthitha Menon et al.A fully autonomous Universal Power Conditioner (UPC) that can accept energy from any micro-energy harvester (e.g., photovoltaic, thermoelectric, electromagnetic, piezoelectric etc.) is proposed. Generally, UPC removes the need of multiple optimized source specific converters. But, the proposed UPC architecture will be Ultra-Low-Power (ULP) with maximized efficiency to support the low energy levels generated by harvesting sources. This UPC uses a … …American Journal of Applied Sciences, Vol. 13, Issue 3 · 28 Mar 2016 · 7,782 accessesView PDF Cite

Research ArticleOpen accessIn the author namesThe Fertility Status of Soils at Rehabilitated Degraded Land in Universiti Putra Malaysia Planted with Pinus caribaea and Swietenia macrophyllaMohammad Nazrin Abdul Malik, Arifin Abdu, Daljit Singh Karam et al.Soil fertility (both physical and chemical) is one of the important factors limiting plant growth. So, the fertility of the soils should be determined before growing crops and after the establishment of forest rehabilitation. A study was conducted to determine the fertility status of soils at rehabilitated degraded land in Universiti Putra Malaysia. The main objective was to compare the … …American Journal of Applied Sciences, Vol. 12, Issue 10 · 5 Nov 2015 · 7,276 accessesView PDF Cite

Research ArticleOpen accessIn the author namesUtility-based Scheduling Frameworks for Efficient Quality-of-Service Differentiation in a Mixture of Real-time and Non-real-time TrafficsOlalekan Bello, Hushairi Zen, AL-Khalid Othman, Khairuddin Abdul HamidThis paper proposes a utility-based scheduling framework for efficient differentiation of users’ Quality-of-Service (QoS) in a broadband wireless access system involving heterogeneous mixed traffic flows. The utility-based scheduling framework, called Maximum QoS Satisfaction (MQS), is based on three novel Radio Resource Allocation (RRA) techniques; delay-based scheduling policy for Real-Time (RT), minimum-rate-based scheduling policy for Non-Real-Time (NRT) and a throughput-based scheduling … …Journal of Computer Science, Vol. 11, Issue 7 · 19 Oct 2015 · 7,139 accessesView PDF Cite

Research ArticleOpen accessIn the author namesComputing Amplify-and-Forward Relay Amplification Factor to Improve Total Capacity at DestinationOlalekan Bello, Hushairi Zen, Al-Khalid Othman, Khairuddin Abdul HamidIn this study, we propose a new Amplify-and-Forward (AF) amplification factor to improve the error performances of the current AF schemes and thus enhance the total capacity at the destination terminal. The proposed scheme has two degrees of freedom, meaning that it contains two variable parameters that can simultaneously vary the amplification factor instead of one as in traditional variable-gain … …American Journal of Applied Sciences, Vol. 12, Issue 8 · 12 Sep 2015 · 7,095 accessesView PDF Cite

Research ArticleOpen accessIn the author namesRADIUS BASED BLOCK LOCAL BINARY PATTERN ON T-ZONE FACE AREA FOR FACE RECOGNITIONMd. Jan Nordin, Abdul Aziz K. Abdul Hamid, Sumazly Ulaiman, R. U. GobithaasanThis study presents a comparison of recognition performance between feature extraction on the T-Zone face area and Radius based block on the critical point. A T-Zone face image is first divided into small regions where Local Binary Pattern (LBP) histograms are extracted and then concatenated into a single feature vector. This feature vector will further reduce the dimensionality scope by … …Journal of Computer Science, Vol. 10, Issue 12 · 27 Dec 2014 · 7,967 accessesView PDF Cite
