"This book presents the basic techniques available to design low power RF CMOS analogue circuits. It gives circuit designers a complete guide of alternatives to optimize power consumption and explains the application of these rules in the most common RF building blocks, LNA, mixers and PLLs. It is set out using practical examples and offers a unique perspective as it targets designers working within the standard CMOS process and all the limitations inherent in these technologies."

"This book presents novel research techniques, algorithms, methodologies and experimental results for high level power estimation and power aware high-level synthesis. Readers will learn to apply such techniques to enable design flows resulting in shorter time to market and successful low power ASIC/FPGA design."

"This new book demonstrates how FGMOS transistors can be used in a low voltage and low power design context. The techniques used provide innovative solutions, often in situations where the limits of the technology in question have been pushed far below the values recommended by the manufacturer.Motivated by consumer demand for smaller, more portable electronic devices, which offer more features and operate for longer on their existing battery packs, cutting edge electronic circuits need to be even more power efficient. This requires the circuit designer to have an understanding of the latest low voltage and low power (LV/LP) techniques which makes use of the floating gate MOS (FGMOS) transistor."

"This highly illustrated and practical book surveys techniques available to protect LV equipment and systems from lightning strikes and other surges. After examining the physical origins and effects of these phenomena, it concentrates on the components and applications of protective measures and systems, placed in the context of current IEC and VDE standards. This unique book provides the reader with a thorough background in almost every aspect of lightning and its impact on electrical and electronic equipment. The contents range from basic discharge processes in air through transient electromagnetic field generation and interaction with overhead lines and underground cables, to lightning protection and testing techniques. This book is of value to anyone designing, installing or commissioning equipment, which needs to be secured against lightning strikes, as well as being a sound introduction to research students working in the field."

"Anoda korban paduan Aluminium yang umum digunakan berpotensi memicu terjadinya Stress Corrosion Cracking dan Hydrogen Embrittlement pada struktur yang diproteksi. Anoda korban potensial rendah Low Voltage Sacrificial Anode dengan potensial dibawah -800 mV vs Ag/AgCl dikembangkan untuk mengatasi permasalahan tersebut. Karakteristik paduan Al-5Zn-0,5Cu dengan variasi penambahan Samarium 0,02 wt , 0,1 wt , 0,3 wt , dan 0,5 wt diteliti pada penelitian ini. Paduan Al-5Zn-0,02In yang umum digunakan juga turut diuji sebagai pembanding. Pengujian efisiensi anoda dengan metode kehilangan berat sesuai standar DNVGL-RP-B401 dan pengujian Electrochemical Impedance Spectroscopy EIS dilakukan untuk mengetahui performa dan karakteristik korosi anoda korban paduan Al-5Zn-0,5Cu-xSm. Penambahan unsur Samarium dengan kadar 0,1 wt menunjukan performa anoda korban yang paling baik dengan kapasitas elektrokimia 2809,80 Ah/kg dan efisiensi 98.

Commonly used Aluminum alloy sacrificial anodes have the potential to trigger the occurrence of Stress Corrosion Cracking and Hydrogen Embrittlement on a protected structure. Low Voltage Sacrificial Anode with potential under 800 mV vs. Ag AgCl was developed to overcome this problem. Electrochemical behaviour of Al 5Zn 0,5Cu alloy with variations of Samarium addition of 0.02 wt , 0.1 wt , 0.3 wt , and 0.5 wt were investigated in this study. The commonly used Al 5Zn 0.02In alloy is also tested as a comparison. Anode efficiency test with weight loss method according to DNVGL RP B401 standard and Electrochemical Impedance Spectroscopy EIS testing was performed to determine the performance and corrosion characteristics of Al 5Zn 0,5Cu xSm alloy. The addition of Samarium element with 0.1 wt content shows the best anode performance with electrochemical capacity 2809,80 Ah kg and 98 efficiency."

"Perkembangan teknologi kelistrikan saat ini sangatlah pesat, hal ini sejalan dengan berkembangnya teknologi peralatan pendukung manusia baik untuk bidang industri ataupun rumah tangga. Sehingga untuk sistem instalasi listrik pada bangunan, khususnya Rumah Mewah diperlukan perencanaan yang matang supaya sistem tersebut mampu bekerja dengan sangat efektif, efisien serta sistem tersebut mampu mengatasi gangguan yang terjadi dalam proses penyaluran atau pendistribusian tenaga listrik di Bangunan tersebut. Kenyamanan dalam bekerja atau beraktifitas tentunya tidak terlepas dari penyediaan penerangan yang baik terutama dimalam hari atau di tempat yang tidak ada ventilasi cahayanya. Selain dari faktor penerangan, kenyamanan dalam beraktifitas akan tercapai jika sirkulasi udara dan tingkat kelembaban ruangan yang baik. Pengaturan penggunaan daya dan penerangan serta beban listrik dalam hal ini adalah dimaksudkan untuk menciptakan suatu ruangan yang nyaman dengan penggunaan daya yang efisien serta tidak berlebihan. Hal ini mengacu pula pada penghematan energi, sehingga pengeluaran biaya lebih ekonomis. Sasaran dan tujuan utama yang ingin dicapai dari sebuah perancangan instalasi listrik pada Rumah mewah ini ialah kebutuhan energi listrik di rumah mewah tersebut tercukupi sampai dengan penambahan daya di masa datang, terjaminnya keamanan seluruh pengguna energi listrik di rumah tersebut, memperlancar seluruh kegiatan dan aktifitas yang dilakukan di rumah tersebut, sistem pendistribusian listrik yang hemat energi dan sangat efisien.

In this time, Technological growth of electrical it's very fast, this matter in line with expanding technology equipments of human being supporter good to industrial area or household. So that for the system of electrics installation in a building needed by planning which enough, so that the system can work effective considerably, efficient and also the system can overcome trouble that happened in course of electric power distribution or channeling in the home. Special target wishing to be reached from a planning of electrics and lighting installation at a good storey building is requirement of the electrics energy that home answered the demand up to addition of the energy in the future, well guaranteed of security all of electrics energy user in the home, to facilitate all activity in the home, efficient and Economical distribution electrics system of energy. Freshmen in working it is of course is not be ready quit of good lighting especially nighttime or in place which there it's no light ventilation. arrangement usage of lighting and energy in this case is meant to create a balmy room with usage of efficient energy in moderation. This matter relate also at thrift of energy, so that expenditure is expense of more economic."
