Because competition for resources generally leads to the spatial exclusion of species using similar resources, it is surprising that foreign spider species are frequently observed in or near the nests of the social spider, Anelosimus studiosus (Hentz 1850) (Theridiidae). In this study, we quantified the frequency of A. studiosus-foreign spider co-occurrence and completed experiments designed to...
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...

wireless sensor networks (wsns) are one of the most interesting consequences of innovations in different areas of technology including wireless and mobile communications, networking, and sensor design. these networks are considered as a class of wireless networks which are constructed by a set of sensors. a large number of applications have been proposed for wsns. besides having numerous applic...
We show that dependence of production on foreign inputs (or non-producible natural resources) can significantly increase the likelihood of indeterminacy. Payment of imported foreign factors of production may act as a semi-fixed cost, amplifying production externalities and returns to scale, making selffulfilling expectations driven busyness cycles easier to arise. This is demonstrated using a s...
The 1980s and 1990s were characterized by an absorption of foreign labour into the Malaysian economy that was unprecedented in terms of numbers and rapidity. From approximately 500,000 foreign workers in 1984 (Ministry of Human Resources, 1991) their numbers shot up beyond 1.2 million in 1991 (Pillai, 1992) and 2.4 million in early 1998 (Utusan Malaysia, 1998). Labour voids manifested particula...
