Abstract
     
 Human acquires more than 90% of the major information by vision. Retina inside of the eye acts not only as an image sensor but also as a computer which extracts various visual information such as color, texture, edge, motion and stereoscopic cues. ‘Seeing is believing’ carries very important idea of human vision because various parts of the brain participate in the vision. This tutorial aims for the comprehensive understanding of human vision by reviewing the following topics.
   1. Basic mechanism of human vision: from retina to brain
   2. Monocular vision: parvocellular and magnocellular pathway
   3. Binocular vision: stereopsis and rivalry
   4. Cortical vision: compression and retrieval of visual information

 Jingon Joung received the B.S. degree in Electrical Engineering from Yonsei University, Korea, in 2001, and the M.S. and Ph.D. degrees in Electrical Engineering and Computer Science from the Korea Advance Science and Technology (KAIST), Korea, in 2003 and 2007, respectively. From March 2007 to August 2008, he was a Postdoctoral Research Scientist in the Electrical Engineering Department, KAIST and, at the same time, he worked as a part time Researcher at Lumicomm, Inc., Korea. From October 2008 to September 2009, he was a Postdoctoral Fellow in the Electrical Engineering Department, University of California, Los Angeles, USA. Since October 2009, he has been working as a Scientist at Advanced Communication Technology Department, Institute for Infocomm Research (I2R), A*STAR, Singapore
 His current research focuses on the convergence of energy efficient, future (5G) wireless communications systems, i.e., the convergence of green information communications technology (ICT). The research on the convergence of green ICT involves various promising technologies, such as multiple-input multiple-output (MIMO) processing, large-scale (massive) MIMO processing, multiuser MIMO channel access, cooperative relaying, distributed antenna systems (DAS), and heterogeneous networks (HetNet) with, for example, 3GPP LTE-A and WiFi. He has been also interested in internet-of-things (IoT), machine-to-machine (M2M) communications, machine learning applications in communications, wireless power transmission, and energy harvesting technologies.
Dr. Joung has served on the editorial board of the APSIPA TRANSACTIONS ON SIGNAL AND INFORMATION PROCESSING (2014–present). He is the recipient of the first prize at the Intel-ITRC Student Paper Contest in 2006, and recognized as the Exemplary Reviewers in 2012 from IEEE COMMUNICATIONS LETTERS, and in 2012 and 2013 from IEEE WIRELESS COMMUNICATIONS LETTERS.
   
Abstract
     
 The tutorial begins with a brief introduction of spectral efficiency (SE) and energy efficiency (EE) in communications. Various definitions of EE will also be covered briefly. One typically used EE, i.e., bits-per-Joule, is theoretically derived and the ideal SE-EE tradeoff is introduced. It is recognized that a power amplifier (PA) is one of the most critical components in wireless communication systems and consumes a significant fraction of the total energy. The fundamental properties of PA, such as linearity and efficiency, are introduced. With the practical characteristics of PA, the detrimental effects of the signal non-linearity and power inefficiency of the PA on the SE, EE, and their tradeoff, are quantified. Next, various existing EE-improving techniques are categorized from three perspectives: PA design, signal design and network design. This broad understanding based on the three categories will help motivate holistic design approaches to mitigate the non-ideal effects in real-life PA devices, and accelerate cross-domain research to further enhance the available techniques for high EE or good SE-EE tradeoff.

Last, the remaining challenges and future work for EE issue will be discussed.
     

Tutorial 3 : Biomedical research with MEMS/microfluidic and non-convertional 3D additive manufacturing
Yong-Jin Yoon (Nanyang Technological University)
Biography    
      Dr. Yong-Jin Yoon joined Department of Mechanical and Aerospace Engineering at Nanyang Technological University (NTU) as an Assistant Professor in January, 2010. He obtained his Ph.D. degree in the Mechanical Engineering at Stanford University in September 2009. During his PhD study, he also obtained two Master degrees in Stanford: one in Electrical Engineering, focusing on MEMS and Signal Processing, and the other in Mechanical Engineering, focusing on Medical Device Design. He was the co-founder of internet and one online game company in South Korea back in year 2000 and he also found a energy management company (Greenvale Co.) in 2009 which demonstrates 20 M USD company evaluation in 2013.
 During his doctoral study in Stanford, he worked in OtoBiomechanics Group in the fields of hearing mechanics. He worked closely with Stanford Medical School Otolaryngology Department for Head, Neck Surgery, focusing on inner- and middle-ear biomechanics, auditory technologies, surgical simulations, μCT and MR imaging. Currently, his researches at NTU include biomimetic electroacoustic MEMS transducer, MEMS tactile sensor for minimally invasive surgery, MEMS/Microfluidic bio-chemical sensor, cell/tissue engineering with 3D printing technology, and multi-scale computational mechanics.
     
Abstract
   
 Research on 3-D MEMS tactile sensor for minimally invasive surgery, biomimetic tactile sensor, resonator tactile sensor for tissue characterization, and tissue scaffold with non-conventional 3D additive manufacturing are introduced. The 3-D tactile sensor, gold stud flip chip bonding is used to mount the force sensor on a substrate for characterization and to simplify the assembly process. The sensor is robust enough to withstand normal forces higher than 20 gf. Microscale biomimetic tactile sensor that inspired from the Meissner corpuscle (MC) mechanoreceptor of the human glabrous skin is designed and fabricated. The Meissner corpuscle MC-inspired tactile sensor is designed with a rigid spherical ball attached on top of a suspended ring structure located at the center of four suspended beams which mimics the biological structure of the Meissner corpuscles. Silicon nanowires (SiNWs) are used as sensing elements which represent the neural signal transmission between the mechanoreceptor and the somatosensory area in brain. The effectiveness of the SiNWs as piezoresistive sensing elements on the bionic Meissner corpuscles mechanoreceptor and on the bare ring-shaped sensing element has been comparatively studied by repeatability and hysteresis tests. The designed artificial tactile sensor offers further potential for a variety of applications, such as integrating on robotic hands, biomedical devices or embedding into artificial skins as sensing elements. For the last research topic, concept of non-conventional 3D additive manufacturing is introduced for biomedical research. The ultimate aim of non-conventional 3D additive manufacturing is to develop a high-throughput, low-cost process for 3D additive manufacturing microstructures in hydrogels. The project centres on Three-Dimensional Holographic Lithography (3DHL) as a novel 3D printed microstructure fabrication process. Applications of these microstructures include making tissue scaffolds for regenerative therapies, for pharmaceutical screening, and for fundamental in vitro biological experiments. 3DHL involves imprinting a set of planar (2D) diffractive optical elements on to, or near, the microfluidic chip.

Abstract
     
 Ultra-low power consumption with high energy efficiency is one of the most significant design parameters in many emerging applications such as implantable biomedical devices, portable electronics, wireless sensor nodes, etc. Supply voltage scaling has been considered as the most effective way of achieving ultra-low power consumption with high energy efficiency. However, ultra-low voltage operation generates many challenging design issues such as significantly degraded parametric margins, large variations, etc. This tutorial will provide a brief introduction of various integrated circuits design techniques that are essential for ultra-low voltage operation. Digital logic gates optimization, energy harvesting circuits, ultra-low voltage memories and SoC examples will be discussed in the tutorial.
