This book describes power management integrated circuits (PMIC), for power converters and voltage regulators necessary for energy efficient and small form factor systems. The authors discuss state-of-the-art PMICs not only for battery powered wearable devices, but also energy harvesting-based devices. The circuits presented support voltage scaling to reduce the overall average power consumption of a wearable device, resulting in longer device operating time. The discussion includes many designs, control techniques and approaches to distribute efficiently the power among different blocks in the device. * Demonstrates for readers how to innovate in designing power management integrated circuits (PMIC) suitable for wearable devices, powered by either battery or harvesting energy; * Introduces a dual outputs switched capacitor, using a single voltage regulator to minimize the area overhead and discusses the effect of having more than two outputs on the area and power efficiency; * Introduces a novel clock-less digital LDO regulator that eliminates the use of the clocked comparator and serial shift register in the conventional design; * Presents experimental results of energy harvesting-based power management units (PMU), using different combinations of power converters and voltage regulators, providing a guide for designers to select the appropriate option based on device requirements.

Australia is one of the most culturally diverse and prosperous societies in the world, and such heterogeneity or pluralism has both advantages and challenges. The Australian government must provide support to and for the integration of migrants, especially among those with a non-English-speaking background (NESB). Investments in information systems (IS) have resulted in the use of information and communication technology (ICT) to raise public awareness of the country's policies, programmes and services. However, communication issues have recently emerged between the government's online IS and the NESB migrants and their communities. Based on their increasing significance in Australia's socio-economic and political landscape, it is necessary not only to identify and understand the needs of NESB migrants, but also to determine the barriers (both perceived and actual) that NESB migrants experience with regard to government online services (otherwise termed 'e-government').
