The optimization of process parameters for the bioconversion of activated sludge by Penicillium corylophilum was investigated using response surface methodology (RSM). The three parameters namely temperature of 33"C, agitation of 150 r/min, and pH of 5 were chosen as center point from the previous study of fungal treatment. The experimental dat

This research is conducted to assess the relationship between the behaviour in, and the reasons for possessing trendy mobile phones among university’s consumers. Using stratified random sampling, a total of 69 participants was selected from both staff (academic and non academic) and students (local and international). A self-administered question

Purpose - The purpose of this paper is to investigate the usability of a web-based OPAC (WebPAC) user interface at the International Islamic University Malaysia (IIUM). It also looks at the applicability of heuristic evaluation in designing a user-centered WebPAC interface. Design/methodology/approach - Based on Nielsen's ten usability heuristi

A single-link flexible manipulator is fabricated. This flexible manipulator is modeled as a SIMO system with the motor-torque as the input and the hub angle and the tip position as the outputs. The two transfer functions are identified using frequency-domain system identification. A polynomial based feedback controller is designed to damp hub angle

A survey was conducted to investigate the relationship between self-esteem and high academic achievement. It is hypothesized that high academic achievers are more likely to possess high self-esteem. Fifty undergraduate students (41 females and 9 males) who received Dean’s List and obtained a GPA of 3.50 and above were contacted and selected as re

Metal matrix composite (MMC) with silicon carbide (SiC) reinforcement in pure aluminum matrix have found wide application in the automotive industry, especially in fiber reinforced pistons and particle-strengthened brake discs. Silicon carbide (SiC) reinforcement provides improved mechanical properties, thermal stability, high temperature formabili

Security of an information system depends to a large extent on its ability to authenticate legitimate users as well as to withstand attacks of various kinds. Confidence in its ability to provide adequate authentication is, however, waning. This is largely due to the wrongful use of passwords by many users. In this paper, the design and development

The positioning systems generally need a good controller to achieve high accuracy, fast response and robustness. In addition, ease of controller design and simplicity of controller structure are very important for practical application. For satisfying these requirements, NCTF (nominal characteristic trajectory following controller) has been propose

The use of students' and teachers' perception of their educational environments can assist educators determine the preference of each group in teaching and learning and thus assist in improving the environment. This would hopefully result in more effective teaching and learning conditions that can thus improve students' achievement. Stu

In the present study, a damage detection problem is formulated as the identification of the spatial stiffness distribution in a damaged composite plate. Full-field heterogeneous curvature fields obtained from an optical deflectometry technique are processed by using the virtual fields method adapted to retrieve the 2D stiffness distribution
