The University of Macau is the only public comprehensive university located in Macau, being the leading tertiary institution of the city which has excellence in teaching, research and service to the community. Founded in 1981, it is the oldest higher educational institution in Macau, as well as the largest university in the city in terms of faculty size and programmes offered.It was established as the University of East Asia, which was a private university followed British university structure and most students came from British Hong Kong. As the preparation of Macau's handover, it was renamed to University of Macau, acquired as a public university and reformed to Portuguese university structure by the government of Portuguese Macau.The university's campus is located in Taipa. It is organised into eight residential colleges and seven academic faculties. The main medium of instruction is English, while certain courses are taught in Chinese, Portuguese and Japanese.The university has been relocated to the new campus in August 2014 at Hengqin Island, Zhuhai, Guangdong but continues to operate under Macau SAR jurisdiction.

A palm-size portable NMR relaxometer system for performing multi-step multi-sample chemical/biological assays, comprising a PCB having a CMOS NMR transceiver and a DMF device integrated thereon. A portable magnet has an inner gap configured to at least partially receive the DMF device. The DMF device comprises a platform of electrodes including a sensing site and receives one or more samples for analysis at an electrode and automatically transports the one or more samples on individual paths sequentially to the sensing site, for performing sensing on each sample sequentially. A Butterfly coil disposed on the PCB and underneath the DMF device and is at least partially received in the inner gap. The Butterfly coil excites the sample at the NMR sensing site by transducing a magnetic field produced at the sensing site to an electrical signal which is processed by the CMOS NMR transceiver to produce an analytical signal.

A portable modular NMR-DMF system for performing chemical/biological assays. The system comprises a PCB having an NMR electronic circuit thereon, wherein the NMR electronic circuit includes a figure-8 shaped RF coil generating a plane-parallel magnetic field. A planar DMF chip comprises a platform comprising an array of electrodes, the array of electrodes including a sensing site located under the figure-8 shaped RF coil. A portable magnet is disposed parallel to the DMF chip and the RF coil. The array of electrodes is configured to receive a sample under detection, move the sample along the array, mix the sample with a probe in the form of at least one droplet with target-specific nanoparticles, and move the mixed sample to the sensing site. A magnetic field corresponding to the mixed sample under detection is produced at the sensing site. The figure-8 shaped RF coil acts to transduce the magnetic field produced at the sensing site to a voltage signal. The NMR electronic circuit receives and processes the voltage signal to produce a resultant signal for analysis.

A compliant gripper with integrated position and force sensors dedicated to automated micro-assembly tasks. The gripper possesses a larger gripping range with a bidirectional drive, and is capable of detecting grasping force and environmental interaction forces in horizontal and vertical axes. The gripper has a compliant rotary flexure bearing. The gripper further has a compliant mechanism with two-stage stiffness designed to provide force sensing with dual sensitivities in two measuring ranges to accommodate the grasping of objects with different sizes. The dual-sensitivity, dual-range force sensor provides finer and coarser force sensing in a small and large ranges, respectively. Analytical models are derived to predict the grasping range, force sensing sensitivities, and force measuring ranges. These models are verified by conducting finite-element analysis simulations.

A mixed signal controller for a power quality compensator includes an analog circuit, an analog-to-digital converter (ADC), and a digital circuit. The analog circuit amplifies an input signal from the power quality compensator by a gain factor and outputs an analog signal, which is converted to a digital signal by the ADC. The digital circuit receives the digital signal, calculates the reference compensating current of each phase and then generates a trigger signal via hysteresis PWM to the power quality compensator. The digital circuit includes an evaluation circuit that calculates a value of the system total harmonic distortion after the power quality compensator compensates power and adjusts the gain factor when the value of the system total harmonic distortion reaches a predetermined threshold.

Drawing on the strategic alliances and innovation literature, this study proposes that the impact of technological collaboration on product innovation is contingent on market competition and sectoral technology characteristics. Specifically, it argues that the generally observed positive effect of technological collaboration on product innovation may be diluted in highly competitive markets, and the interactive effect of technological collaboration and market competition on product innovation will be further moderated by sectoral technological intensity. Data on the product innovation and technological collaboration of 944 Chinese firms across five manufacturing sectors provide robust support for the contingent effects of technological collaboration on product innovation. © 2011 Elsevier B.V.
