An adaptive fuzzy sliding mode controller (AFSMC) is adopted to reduce the 2D flow-induced vibration of an elastically supported square-section cylinder, free to oscillate in stream-wise andtransverse directions in both lock-in and galloping regions. The AFSMC strategy consists of a fuzzy logic inference system intended to follow a sliding-mode controller (SMC), and a robust control syste...

To maintain the stability trajectory of vehicles under critical driving conditions, anti lock-anti skid controllers, consisting of four anti-lock sub-controllers for each wheel and two anti-skid sub-controllers for left and right pair wheels have been separately designed. Wheel and body systems have been simulated with seven degrees of freedom to evaluate the proper functioning of controllers. ...

Locks are efficient concurrent control mechanisms to ensure that shared resources are accessed by only a single thread in multi-threaded applications. However, for multi-core systems, lock usage leads to lock contention, which degrades program performance, increases system response time, and negatively affects scalability. This paper initially models lock contention from two aspects: static str...

Many businesses have turned to customer relationship management (CRM) to strategically position themselves in electronic marketplaces with information and communication technologies (ICT). With greater emphasis placed on the application of technology, does the infusion of ICT influence a business’ ability to retain its customers? This study examined the relationships among three CRM elements be...

This paper examines the role of technological and institutional ‘lock-in’ as a barrier to more sustainable innovation, and the implications of this for determining appropriate policy responses. It begins by reviewing the idea of lock-in, and recent work applying this concept to carbon-based energy systems. It then summarises work by the author and colleagues outlining policy instruments to prom...
