The Use of Sinusoidal Illumination for Optical Super-Resolution and
Depth Estimation
Panos Papamichalis, Southern Methodist University, USA
Scenes captured by a digital camera are subject to constraints imposed both by the camera optics
and the sampling density of the digital sensor. Regardless of the sampling density, the camera
optics limit the bandwidth of the analog image projected on the sensor, because of diffraction. This
presentation investigates how illuminating the scene with sinusoidal patterns can help retrieve
frequencies beyond the diffraction limit. The mathematical formulation reveals the appropriate
positioning of the projector and the camera to achieve this for the different projected patterns. The
same formulation also shows how depth information can be retrieved from the same set-up.

High-Accuracy Machine Vision Technology Using Sub-Pixel Image
Matching - From 3D Vision to Medical Image Analysis Takafumi Aoki, Tohoku University
This paper presents fundamentals of Phase-Only Correlation (POC) --- a technique for highaccuracy registration of 1D, 2D and 3D signals using phase information of discrete Fouriertransform. Since 1990s, our research group has developed a novel technique of phase-based image
matching for fingerprint verification and industrial machine vision. We have recently proposed anefficient image correspondence algorithm using POC, which can find pairs of corresponding points
between the given two images with sub-pixel accuracy. This allows us to apply the POC techniqueto a wide range of applications, including smart image sensors, microscope image analysis, passive
3D vision, automotive image processing, image-based human interface, biometrics authentication,and medical image analysis.

An Objective Quality Assessment Model of Multi-Channel Audio Coding
Systems
Koeng-Mo Sung, Seoul National University, Korea
In the quality assessment of multi-channel audio coding systems, both timbral and spatial quality
should be considered. Since conventional objective assessment algorithms for monaural or stereo
signal measure only timbral quality in general, it is inadequate to assess multi-channel audio
coding systems. This paper introduces four spatial measures that estimates human’s nonlinear
behaviors on perceived directions of sound sources. Combining the proposed spatial measureswith the timbral measures, the proposed objective model of multi-channel audio coding systems
achieves an outstanding performance in the prediction of subjective assessment standards, ITU-R
Recommendation BS.1116-1 and BS.1534-1.

Development of Acoustic Systems Realizing Communications with High

Yôiti Suzuki, RIEC, Tohoku University
Realization of communications with a high sense-of-presence necessitates development of systems
based on knowledge related to human hearing and multi-modal perceptual processing. Therefore,
three-dimensional (3D) sound localization recognition is examined as multi-modal perceptual
processing based on hearing and on self-motion perception. A spherical array comprising 252
microphones was developed for comprehensive recording of a 3D sound field.
A 3D sound reproduction system implemented with a 157-loudspeaker array based on higher-order
Ambisonics is combined with a 3D projection display to reproduce high-definition audio-visual
information. This developed system is useful to improve understanding of human audio-visual
perception.

Strategy of Carrier Control of Carbon Nanotube Transistor
Young Hee Lee, Sungkyunkwan University, Korea
Nanocarbons such as fullerenes, carbon nanotubes, carbon nanofibers, graphite oxides, andgraphenes has been the key words in 21th century and has led nanoscience and nanotechnology.
Due to the various allotropes of carbons, unexpected scientific new findings and their related
applications have been extensively investigated. In this seminar, I will discuss various
issues mainly related to their applications to energy area and electronic devices. Pure carbon
nanotubes have been known to exhibit ambipolarity. This is very different from the conventional
semiconductors that are controlled by an intentional doping with extrinsic materials. The
ambipolarity has been a serious drawback in adopting carbon nanotubes for CMOS technology.
Carbon nanotubes show p-type behavior in ambient conditions. The difficulty arises from theabsence of stable n-type dopants in ambient conditions. A series of chemical approaches have been
done in our group to search for n-type dopants. NADH and viologen molecules have demonstrated
successfully to show n-type behavior by donating electrons to nanotubes and furthermore showhigh stability in ambient conditions.[1-5] In addition to these approaches, we will also demonstrate
a way of utilizing ambipolarity of nanotuibes without such intentional dopings that ambipolarity
is in fact advantageous in fabricating CMOS inverter and logic circuits.[6] I will also discuss a newroute of graphene synthesis and the related applications.[7,8][1] K. Kim et al., J. Am. Chem. Soc. 130, 12757-12761 (08).

Green-Nanoelectronics Oriented Nanoscopic Plasma Control
Rikizo Hatakeyama, Tohoku University
In this report, our emphasis is placed on green information-electronics nanodevices of carbon
nanotubes (CNTs) synthesized and functionalized by nanoscopic plasma process control. Firstly,
the single-walled carbon nanotubes (SWNTs) growth from nonmagnetic catalysts is successfully
realized by diffusion plasma CVD toward a study on novel nano-magneticsemiconductor
properties. Secondly, a photovoltaic phenomenon is observed when pn junctions based on fullerene
encapsulated SWNTs are illuminated by lights in the infrared region, which is expected to makefor a new concept of solar nanocells. Thirdly, when biomolecule DNA is encapsulated inside CNTs,
their semiconducting transport properties are found to be versatilely controlled depending on the
DNA bases which own different ionization (or redox) potentials.

Anodic Titanium Oxide Nanotube Film: Formation and Application to

Michio Niwano, RIEC, Tohoku University
Anodization of titanium in electrolyte is a promising method for fabrication of titanium oxide (TiO2)
nanotubes. For the application of TiO2 nanotubes to the negative electrode of a dye-sensitizedsolar cell (DSC) we need to form a TiO2 nanotube film directly on a TCO layer. It is important
for the formation of such a TiO2 nanotube film to elucidate and control on the nanometer scale
the anodization process of titanium that would be greatly influenced by the electrolyte. In thepresent study, therefore, we have investigated the influence of constituents of the electrolyte on theanodization process.

Development of Super-Precise Ultrasonic Method and System for
Measuring Zero-CTE Temperature of TiO 2-SiO 2 Ultra-Low-Expansion
GlassesJun-ichi Kushibiki, Tohoku University
Ultra-low-expansion (ULE) glasses having a zero-CTE (coefficient of thermal expansion) arounddesired temperatures are required for basic substrate materials for optical components in extreme
ultraviolet lithography (EUVL) systems as well as in an ultrahigh-finesse optical cavity for the
next-generation frequency standard. TiO2-SiO2 glass is the most suitable candidate. It is wellknown that commercial ULE glasses contain periodic variations in TiO2 concentration (namely
striae) formed during the glass fabrication process, so that there must exist some CTE distributions
and some deviations of zero-CTE temperature, T(zero-CTE), from desired temperatures. This is aserious problem for the optical applications.
In this paper, we developed a practical method and system for super-precise evaluation of T(zeroCTE) of TiO 2-SiO 2 glasses using our ultrasonic micro-spectroscopy (UMS) technology with aresolution of 0.4°C at 225 MHz. We applied the system to realize a glass ingot with T(zero-CTE)
around 25°C by controlling fictive temperature TF of the glass ingots homogenized by the zonemelting method.

Managing Multipartite Entanglement Using Photons
Nobuyuki Imoto, Osaka University, Japan
Entanglement is one of the most bizarre properties in quantum mechanics and is an essential
resource for quantum information processing. It is difficult to create a large scale entanglement
and also difficult to protect it from noisy circumstance. It is possible, however, to enlarge
an entanglement network with a simple scheme and protect it from decoherence using DFS(decoherence-free subspace). Once we create multipartite entanglement, we can utilize it for several
tasks such as one-way computing and joint weak measurement by entangling the meters. I reportour recent experiments using photons.

Broadband Distributed Antenna Network and Its Related Wireless
Techniques
Fumiyuki Adachi, Tohoku University
To realize communications with high sense of presence everywhere, broadband wireless technology
which can achieve higher-than-1Gbps data transmission with extremely low transmit power is
indispensable. We have been studying the broadband distributed antenna network (DAN) andthe frequency-domain block signal detection. In broadband DAN, many antennas are spatiallydistributed over a service area and they are connected by means of optical fiber cables with DAN
signal processing center. A group of distributed antennas cooperatively serve mobile users using
spatial multiplexing, diversity, or relaying technique. We will introduce the recent research
progresses of broadband DAN and its related wireless techniques.

256. First, we describe the difficulties involved in realizing a multiplicity of 256, and present
transmission results for 256 QAM coherent transmission over 160 km. We mention thepossibility of a multiplicity of 512. In addition, we have proposed combining OTDM and the QAM
technique to realize high-speed, spectrally efficient transmission. I will describe how such anadvanced transmission technique can be realized.

Reliable Application Layer Multicast over Heterogeneous Networks
Nei Kato, Tohoku University
Due to the deployment of hybrid wired/wireless networks, the reliable content delivery over such
heterogeneous networks becomes a significant issue. Application layer multicast is a promising
approach to delivering streaming media contents to a large number of users. However, frequent
node joining and departure due to mobility in wireless networks results in undelivered streams.
In addition, the link capacities are totally different in heterogeneous networks. In this paper, we
propose a method to guarantee the content delivery in a dynamic network, while meeting various
bandwidth constraints by using layered multiple description coding.

The Quest for Tbits/in2 : Understanding and Manipulating Nanoscale
Magnetism
Tom Thomson, University of Manchester, UK
The phenomenal success of the hard disk drive (HDD) industry in providing cheap and almost
limitless data storage capacity continues to be a key enabling technology that unpins almost every
aspect of a modern information society. The principal magnetic components of HDD’s are the head
which incorporates both write and read elements, and the recording medium. In this talk I will
focus on the scientific challenges encountered in creating magnetic media with ever greater areal
density. Three potential schemes are currently under consideration to enable > 1Tbit/in2 recording;(i) conventional or not so conventional perpendicular media (ii) bit patterned media (BPM) and(iii) energy assisted recording. All of these schemes have some media requirements in common,in particular the necessity to understand and control anisotropy distributions and the need toengineer the relationship between magnetisation reversal and thermal stability. Our recent work
exploring reversal and thermal stability in exchange spring thin films using magnetometry andneutron scattering, together with results on determining anisotropy distributions in BPM provide
some insights into the critical issues needed to create > 1Tbit/in2 recording media.

Future Foresight and Today’s Str uggle in High Density Information
Storage
Hiroaki Muraoka, RIEC, Tohoku University
Fast growth of amount of created information continues, 10 times in these 5 years. The demandof areal density of HDD is therefore strong. The 1 Tbit/inch2 is just around the corner, where
the bit size is approximately 25 nm, but several challenges are foreseen to go beyond. The firstchallenge will be magnetic uniformity limit at bit size of 8 nm or density of 10 Tbit/inch2. Magnetic
fluctuations such as switching field distribution or grain size dispersion must be solved for SNR or
error rate. Next challenge will be at around 3 nm or 100 Tbit/inch2, where we will confront thermal
and granular limit. Obviously the ultimate density limit is the atomistic dimension of 0.2 nm, or
10 Peta-bit/inch2. Entirely new idea will be required, but we have another 30 years even with thegrowth rate of 140%/year.

Power Management for VLSIs - a Power Electronics Perspective
Wai Tung Ng, University of Toronto, Canada
The aggressive scaling of CMOS technology has allowed rapid increases in the gate density
and gate count in modern VLSIs. The power consumed by today's VLSI chips under maximum
performance situation could cause over-heat and even become destructive. This is especially criticalin portable multimedia and telecommunication products where form factor, cooling and battery life
impose very stringent limitations. Power management is currently one of the most critical enabling
technologies to further increase VLSI performance and integration density. Dynamically scaling of
the power supply voltage and clock frequency according to performance needs has been investigatedfor more than 10 years. Most of the previous work focused only on saving power at the VLSI chiplevel. The design of the power efficient variable output power supplies (DC-DC converters) is often
assumed to be trivial and as an afterthought. While significant power saving has been reported
at the VLSI chip level, the overall power saving at the system level is often difficult to realize. In
this paper, we will examine some of the design techniques used to broaden the power conversion
efficiency and to provide tight regulation in digitally controlled switched mode power supplies
suitable for VLSI power management.

Michio Niwano, RIEC, Tohoku University
Anodization of titanium in electrolyte is a promising method for fabrication of titanium oxide (TiO2)
nanotubes. For the application of TiO2 nanotubes to the negative electrode of a dye-sensitized solar cell(DSC) we need to form a TiO2 nanotube film directly on a TCO layer. It is important for the formationof such a TiO2 nanotube film to elucidate and control on the nanometer scale the anodization process oftitanium that would be greatly influenced by the electrolyte. In the present study, therefore, we haveinvestigated the influence of constituents of the electrolyte on the anodization process.

Development of Super-Precise Ultrasonic Method and System for Measuring
Zero-CTE Temperature of TiO2-SiO2 Ultra-Low-Expansion Glasses
Jun-ichi Kushibiki, Tohoku University
Ultra-low-expansion (ULE) glasses having a zero-CTE (coefficient of thermal expansion) arounddesired temperatures are required for basic substrate materials for optical components in extreme
ultraviolet lithography (EUVL) systems as well as in an ultrahigh-finesse optical cavity for the nextgeneration frequency standard. TiO2-SiO2 glass is the most suitable candidate. It is well-known thatcommercial ULE glasses contain periodic variations in TiO 2 concentration (namely striae) formed
during the glass fabrication process, so that there must exist some CTE distributions and somedeviations of zero-CTE temperature, T(zero-CTE), from desired temperatures. This is a serious
problem for the optical applications.
In this paper, we developed a practical method and system for super-precise evaluation of T(zero-CTE)of TiO2-SiO2 glasses using our ultrasonic micro-spectroscopy (UMS) technology with a resolution of
0.4°C at 225 MHz. We applied the system to realize a glass ingot with T(zero-CTE) around 25°C bycontrolling fictive temperature TF of the glass ingots homogenized by the zone-melting method.

Atomically Controlled Processing for Future Si-Based Devices
Junichi Murota, RIEC, Tohoku University
Atomically controlled processing based on atomic-order surface reaction control is indispensable
for future ULSI fabrication. In Si or Si 1-xGe x(100) epitaxial growth, C atomic-layer doping atheterointerface of strained Si1-xGex/Si suppresses strain relaxation as well as intermixing. In P atomiclayer doping for Si/strained Si0.55Ge0.45/Si(100), low-temperature and high-growth-rate Si cap layer
growth suppresses the P surface segregation. Tensile strain in Si layer reduces the incorporated P
amount around the heterointerface. The Si layer growth rate and the electrical activity of P and B
atoms for heavy doping over around 1020 cm-3 in tensile-strained Si are lower than those in unstrainedSi.

To realize communications with high sense of presence everywhere, broadband wireless technology
which can achieve higher-than-1Gbps data transmission with extremely low transmit power is
indispensable. We have been studying the broadband distributed antenna network (DAN) and thefrequency-domain block signal detection. In broadband DAN, many antennas are spatially distributed
over a service area and they are connected by means of optical fiber cables with DAN signal processing

Fundamental Technologies towards New Paradigm VLSI Computing
Takahiro Hanyu, RIEC, Tohoku University
In order to solve the recent VLSI problems causing performance and reliability degradation, we focus
on a “new-paradigm VLSI computing” concept that investigates the optimal design through all the
VLSI design layers such as a device/material design level, a circuit-architecture level, a logic-synthesis
level, a system-architecture level, and an application-oriented algorithm level. The use of “logic-inmemory VLSI architecture,” where storage elements are distributed over a logic-circuit plane, makes
global wires reduced greatly. To implement a logic-in-memory VLSI compactly, we utilize multifunctional and nonvolatile devices such as ferroelectric devices, TMR (MTJ) devices and phase-change
devices.

Adaptive Functional-Module Selection for Live-Feeling Communication
Michitaka Kameyama, Tohoku University
We present an approach to the real-world live-feeling communication. The application is based on an
adaptive TV-set that reconfigures itself based on the user emotional state, in order to provide the user
with the most satisfactory viewing experience. The setup contains cameras that can be zoomed andpan/tilted and microphones that can be oriented toward different sources of sounds. The content of thecameras and microphones is transmitted to the TV screen and speakers. The user is observed throughanother set of video cameras that perform face detection and posture detection. Using this information
the system estimates the user's emotional state and adapts its cameras and microphones action.
The system reconfigures itself by adaptively selecting functional modules. The functional modules
represent all the available computational resources and each particular selection of functional modules
generates a different output behavior. The reconfiguration uses cellular automaton (CA) to generatecombinations of functional modules. The use of the cellular automaton is motivated by the fact that by
only specifying a set of local rules, novel behaviors can be generated. Also, the pseudo-random behaviorof the CA is used to actively query the user for emotional responses and thus permits to distinguishand categorize emotional user state even if they are not explicitly recognizable.
The advantage of using the proposed approach is in the fact that it is robust because thereconfiguration of the whole system is directly dependent on the perceived emotional user state.
This means that the proposed approach is designed to work in a various environments as well as
various task contexts. Moreover, by adaptively selecting these resources we can minimize the power
consumption. This is in contrast to the traditional behavioral approach to robotics where the behaviors
are predefined and are always active. Another advantage resides in the fact that the CA based
reconfiguration is scalable and can be extended to a multi-level functional behavior generation.

Model checking has been successfully applied to software and hardware verification. Higher-order model
checking is an extension of model checking, where models are described as higher-order functional

to program verification. We have implemented a higher-order model checker TRecS and constructed asoftware verification tool on top of it. To our knowledge, TRecS is the first implementation of a higherorder model checker; Despite its theoretical interests, there has been no practical implementation,
because of the extremely high time complexity of higher-order model checking.
