Machine tool chatter is a type of intensive self-excited vibration of the individual components in a machine-tool-fixture-work system. Chatter affects the cutting process and may lead to negative effects concerning surface quality, cutting tool life, and machining precision. However, modern manufacturing industries and their end users demand fine s

Soda lime glass is a very important material in diverse manufacturing industries, including automotive, electronics, and aerospace. In these applications, the glass surface needs to be defect free and without impurities. However, the machining of glass is difficult due to its inherent brittleness which leads to brittle fracture and easy crack propa

This presentation aims to provide participants with information regarding the protection provided under the Consumer Protection Act 1999, among others: protection of buyers / consumers specifically in the auto – sector and in general expensive consumer product like household electrical and electronic appliances;prompt replacements for defective p

Tronoh’s raw sand was converted into fine silica particles via a series of milling process. Addition of these fine particles into iron composite was found to modify its mechanical properties. The composite was prepared using powder metallurgy technique with varying percentage of silica particles; 5, 10, 15, 20 and 25wt%. The composites were sinte

A delay in completion of housing project is a common phenomenon in the housing industry in Malaysia. Buyers are often forced to accept the fact that it is 'better late than never'. Late delivery has several negative implications to the customers which actually causes financial, social and emotional problems to the house buyers. This study a

Background: An insult during a critical period of fetal development may result in increased risk for development of hypertension. Objective: This study aims at evaluating the effects of high maternal dietary sodium during pregnancy and lactation on their offspring’s blood pressure at 16 weeks upon 1 month of high dietary sodium challenge. Materia

The conventional wisdom of the obsoleteness of traditional management accounting tools and appropriateness of the contemporary ones has not been empirically established. Several studies have been conducted to ascertain the reasons for such unexpected findings. However, these studies are majorly survey based approaches and there are calls for more r

This study examines the relationships between oil prices and macroeconomic variables such as industrial/manufacturing production index, consumer price index, real effective exchange rates, lending rates and stock price index in Australia and New Zealand within the framework of hidden cointegration technique and crouching error correction model (CEC

Skyline queries provide a flexible query operator that returns data items (skylines) which are not being dominated by other data items in all dimensions (attributes) of the database. Most of the existing skyline techniques determine the skylines by assuming that the values of dimensions for every data item are available (complete). However, this as

A hash function usually has two main components: a compression function or permutation function and mode of operation. In this paper, we propose a new concrete novel design of a permutation based hash functions called Gear. It is a hash function based on block cipher in Davies-Meyer mode. It uses the patched version of Merkle-Damgård, i.e. the wid
