"Electromagnetic vibration energy harvesting devices introduces an optimization approach which is applied to determine optimal dimensions of the components (magnet, coil and back iron). Eight different commonly applied coupling architectures are investigated. The results show that correct dimensions are of great significance for maximizing the efficiency of the energy conversion. A comparison yields the architectures with the best output performance capability which should be preferably employed in applications. A prototype development is used to demonstrate how the optimization calculations can be integrated into the design?flow. Electromagnetic vibration energy harvesting devices targets the designer of electromagnetic vibration transducers who wishes to have a greater in-depth understanding for maximizing the output performance."

"[Sejalan dengan misi Universitas Indonesia yang ingin menjadi green campus, maka Fakultas Teknik UI meluncurkan program “FTUI towards green and sustainable society”. Salah satu fokus dalam program ini adalah manajemen energi. Namun, Fakultas Teknik ternyata mengkonsumsi listrik PLN paling banyak dibandingkan dengan fakultas lainnya di UI sehingga muncullah ide untuk menciptakan sumber energi alternatif berupa anak tangga pemanen energi yang dapat diaplikasikan di lingkungan FTUI. Langkah pertama dalam merancang anak tangga pemanen energi adalah pengumpulan data kebutuhan calon pengguna melalui kuisioner. Kemudian hasil kuisioner diolah menggunakan metode TRIZ untuk mendapatkan spesifikasi produk. Setelah itu, dibuatlah desain anak tangga pemanen energi beserta prototype-nya. Eksperimen terhadap prototype dilakukan di Laboratorium Faktor Manusia Ergonomics Centre dengan menggunakan motion capture dan force platform. Data GRF dari eksperimen dianalisis menggunakan ANOVA, sedangkan data gerakan diintegerasikan dengan Software Jack untuk dianalisis apakah desain yang diajukan ergonomis atau tidak., In line with the mission of the Universitas Indonesia that wants to be a green campus, the Faculty of Engineering, Universitas Indonesia launched the program of "FTUI towards green and sustainable society". One focus in this program is the energy management. However, the consumption of electricity in Faculty of Engineering is the highest compared to other faculties in UI. Therefore, coming the idea to create an alternative energy source in the form of stairs energy-harvester that can be applied in FTUI. The first step in designing stairs energy-harvester is collecting the data of potential users’ needs through a questionnaire. Then, the results of questionnaires processed using TRIZ method to obtain product specifications. Thereafter, the design of stairs energy-harvester were made along with its prototype. An experiment towards prototype carried out in the Laboratory of Human Factors Ergonomics Centre by using motion capture and force platforms. GRF data from experiments were analyzed using ANOVA, while the movement data were integrated to Jack Software to be analyzed whether the proposed design is ergonomic or not.]"

"This book provides an overview of the latest research and development of new technologies for cognitive radio, mobile communications, and wireless networks. The contributors discuss the research and requirement analysis and initial standardization work towards 5G cellular systems and the capacity problems it presents. They show how cognitive radio, with the capability to flexibly adapt its parameters, has been proposed as the enabling technology for unlicensed secondary users to dynamically access the licensed spectrum owned by legacy primary users on a negotiated or an opportunistic basis. They go on to show how cognitive radio is now perceived in a much broader paradigm that will contribute to solve the resource allocation problem that 5G requirements raise. The chapters represent hand-selected expanded papers from EAI sponsored and hosted conferences such as the 12th EAI International Conference on Mobile and Ubiquitous Systems, the 11th EAI International Conference on Heterogeneous Networking for Quality, Reliability, Security and Robustness, the 10th International Conference on Cognitive Radio Oriented Wireless Networks, the 8th International Conference on Mobile Multimedia Communications, and the EAI International Conference on Software Defined Wireless Networks and Cognitive Technologies for IoT."

"This textbook introduces Wireless Powered Communication Networks (WPCNs) as a promising paradigm to overcome the energy bottleneck suffered by traditional wireless communication networks, as well as emerging Internet-of-Things networks. It selectively spans a coherent spectrum of fundamental aspects in WPCNs, such as wireless energy transfer (WEH) techniques, radio frequency (RF) energy harvesting receiver model, simultaneous wireless information and power transfer (SWIPT), as well as the rate-energy tradeoff arising from the joint transmission of information and energy using the same waveform. It covers network models for WPCNs, including the baseline and dual-hop WPCN models and a variety of related extensions. This book further examines the key factors including throughput, fairness, and security that must be taken into account for impeccable operation of WPCNs. The new IoT applications are targeted as a key element in those factors. It will also include exercises and examples throughout the book, as well as their PLS solutions.This is the first textbook examining the current research to provide a unified view of wireless power transfer (WPT) and information transmission in WPCNs from a physical layer security (PLS) perspective. Focused on designing efficient secure transmission schemes, analyzing energy evolvement process, and evaluating secrecy outage performance under different channel state information (CSI), the results presented in this book shed light on how to best balance security and throughput with prudent use of harvested energy in WCNs. It also provides an overview of the WPCNs by introducing the background of WPT, followed by a summary of the research conducted in the field. The authors describe the physical-layer security (PLS) problem in WPCNs, including the causes and the impacts of the problem on the performance of WPCNs. The authors extend the discussions by introducing the applications of WPCNs in the IoT.From the Internet of Things (IoT) point of view, this textbook reviews the opportunities and challenges for the lately-emerged WPCN to seamlessly integrate into the IoT ecosystem. It specifically addresses the maximization problem of uplink and downlink sum-throughout in a dual-hop WPCN, while taking fairness among WPCN users as a constraint. The results provided in this book reveal valuable insights into improving the design and deployment of future WPCNs in the upcoming IoT environment.This textbook targets advanced-level students studying wireless communications and research engineers working in this field. Industry engineers in mobile device and network development business with an interest in WPCNs and IoT, as well as their PLS solutions, will also find this book useful."
