In this paper, a multiwavelength two-mode Brillouin fibre laser generated by two-mode optical fibre (TMOF) is proposed and demonstrated experimentally. The system comprises a 500 m long TMOF. A tunable laser source amplified by a high power erbium doped fibre amplifier acts as the Brillouin pump (BP) followed by a single mode fibre Bragg grating as

Duplex stainless steel (DSS) is a material with high potential successes in many new applications such as rail car manufacturing, automotive and chemical industries. Although DSS is widely used in various industries, this material has faced wear and hardness problems which obstruct a wider capability of this material and causes problems in current

Nowadays, iris recognition is widely used for personal identification and verification based on biometrical technology, especially in the smartphone arena. By having this iris recognition for identification and verification, the smartphone will be secured since every person have their own iris type. In this paper, we proposed an efficient iris reco

Currently, magnetic resonance imaging (MRI) has been utilized extensively to obtain high contrast medical image due to its safety which can be applied repetitively. Edges are represented as important contour features in the medical image since they are the boundaries where distinct intensity changes or discontinuities occur. Many traditional algori

Femtocells are a promising technology to increase the capacity, efficiency and the coverage of the cellular networks. However, several challenging issues must be addressed and resolved before femtocell technology becomes a reality. One of the most important challenges is assessing, modelling and mitigating the interference. This book reviewed diffe

Limb loss is a growing problem due to the increasing number of accidents worldwide. A cybernetic prosthesis is a device which can assist individuals with hand disabilities by enabling them to have some of the hand capabilities of an able bodied individual. Extracting hand grip force and wrist angle information from forearm electromyogram (EMG) sign

Various formulations of calcium phosphate cement (CPC) have been developed to get cement paste with optimum setting times, injection capabilities, as well as mechanical and biological properties. This is important to ensure that CPC is applicable for clinical uses as bone filler materials. The existing studies on CPC have investigated factors affec

Calcium phosphate cement has been prepared via chemical precipitation method for injectable bone filling materials. Calcium hydroxide, Ca(OH)2, and diammonium hydrogen phosphate, (NH4)2HPO4, were used as calcium and phosphorus precursors respectively. The synthesized powder was mixed with water at different powder-to-liquid (P/L) ratios, which was

Micro-EDM has become one of the most accepted advanced manufacturing technologies in micro-level fabrication. One of the main challenges in micro-EDM is to fabricate non-circular electrode. In order to overcome this challenge, this study presents a simple and inexpensive process to fabricate non-circular electrode by using localised electrochemical

A single series resonant converter has been designed to balance the voltage level of a storage battery for electric vehicles. The proposed design has been simulated and verified by using two 100F supercapacitors instate of the conventional rechargeable battery. A voltage monitoring circuit detects the voltage condition of the individual capacitor a
