Research ArticleOpen accessIn the abstractMultiaxial Fatigue Strength to Notched specimens made of 40CrMoV13.9Abedin Gagani, Raffaella Aversa, Relly Victoria V. Petrescu et al.Fatigue is a process (succession of mechanisms) which under the action of time-varying strains or deformations modifies the local properties of a material. These can lead to the formation of cracks and eventual rupture of the structure. Fatigue is in particular characterized by an extent of variation in stress which may be well below the yield strength of the material. … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 31 Dec 2016 · 8,208 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Interregional Freight Generation Modelling Methods by using Nationwide Commodity Flow Survey DataWirach HirunA trip generation model is one of the four parts of the classical transport planning model, which explores the volume of trip or freight at the originating and destination points of a traffic analysis zone. The process of calibrating a trip generation model needs appropriate data. Freight transport data are always robust and a powerful calibration technique is required to … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 18 Aug 2016 · 8,113 accessesView PDFCite

Research ArticleOpen accessIn the abstractHYBRID SEARCH AND DELIVERY OF LEARNING OBJECTS SYSTEMAnthony N. Ilukwe, Yevgen BiletskyRetrieving learning material from the internet is a tedious process that has begged for a solution to filter out of the cluster of data and irrelevant material on the internet and deliver material that is relevant to a specific user. The Hybrid Search and Delivery of Learning Objects (HSDLO) system, put forward in this study, facilitates the personalized search and … …Journal of Computer Science, Vol. 10, Issue 6 · 25 Jan 2014 · 6,604 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnvironmental Ethics in Governing Recycled Material Styrofoam for Building Human HabitatRavichandran Moorthy, Kartini Aboo Talib Khalid, Suhana SaadStyrofoam is extensively used in food packaging businesses throughout the world. Its light weight makes it a favorite food package for entrepreneurs in food businesses. However, unlike its content, the food, which decomposed easily after some time, Styrofoam remains un-decomposed due to its oil-based structure. This study discusses the prospects of re-utilization of Styrofoam as environmentally friendly recycled material. This … …American Journal of Environmental Sciences, Vol. 8, Issue 6 · 28 Dec 2012 · 8,150 accessesView PDFCite
Research ArticleOpen accessIn the abstractAcoustic Properties of Innovative Material from Date Palm FibreLamyaa Abd AL-Rahman, Raja Ishak Raja, Roslan Abdul Rahman, Zawawi IbrahimProblem statement: An organic material is one of the major requirements to improve living environment and the invention of materials need to consider for the best solution. This study presents an experimental investigation on pure porous from Date Palm Fibre (DPF). The effectiveness of sound absorbers depends on structural architecture of this material. This study was conducted to examine the … …American Journal of Applied Sciences, Vol. 9, Issue 9 · 17 Jul 2012 · 8,099 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy on Optical Constants and Refractive Index Dispersion of Neutral red Doped Polymer FilmHussain A. BadranProblem statement: The some optical constants polymer thin film with red dye 3-amino-7-dimethylamino-2-methyl phenazine (NR) as the guest material and Polyvinylpyrrolidone (PVP) as the host material were prepared by adulteration and spin-coating methods. Approach: The values of some important parameters (refractive index n, extinction coefficient K and dielectric constant ε∞) of polymer thin film are determined from these spectra. Results: … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 26 Dec 2011 · 8,923 accessesView PDFCite
Research ArticleOpen accessIn the abstractMechanical Strength and Durability Properties of High Performance Mortar Containing Densified Silica FumeCheah Chee Ban, Mahyuddin RamliProblem statement: Numerous data and information on pozzolanic reaction and microfiller properties of silica fume were derived from laboratory investigation on silica fume in undensified form. Currently, due to low bulk density of undensified silica fume which poses problem in transportation and handling of the material, silica fume are commercially supplied in densified form. Densification process used to increase bulk … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 7,958 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization of Mix Proportion of High Performance Mortar for Structural ApplicationsCheah Chee Ban, Mahyuddin RamliProblem statement: Mortar mix is a major construction material in fabrication of ferrocement structural elements. However, there have been scarce amount of technical data available on suitable mix proportion to achieve structural grade mortar with specific strength requirement and adequate level of workability for proper placement into construction formwork. Moreover, current practice in ferrocement construction work which uses mortar mix … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 5 Nov 2010 · 8,819 accessesView PDFCite
