    Title
    Möbius-invariant curvature-based surface energies and surface creases
    Time
    Wednesday, 16:15-17:00
    Location
    UBIC 3D Theater
    Abstract
    This my talk is based on recent research results obtained jointly with Shin Yoshizawa (RIKEN). Curvature-based energies are widely used in mathematical, physical, engineering, and biological studies. Various invariance properties of curvature-based energies make them important for numerous pattern recognition, computer vision, and geometric modelling applications. In this talk, I deal with Möbius invariant curvature-based surface energies. The Lie group of Möbius transformations is generated by inversions in spheres and, in addition to the sphere inversions, includes the translations, rotations, and similarity transformations. I derive Möbius-invariant surface energies which involve derivatives of the principal curvatures along their corresponding curvature lines. I demonstrate how such surface energies can be used for robust detection of salient surface creases.

    Differentiating traditional and popular music by analyzing the social structure of fame: a computer simulation of fan-artist affiliation networks

    Abstract
    Discourse about music—in both ordinary language and scholarly contexts—frequently invokes a contrast between “traditional” and “popular” musical culture types. While the pure types—“traditional”, “popular”—are generally understood to be related to broader patterns of cultural mediaization (premediated for pure “traditional”; mass mediated for pure “popular”), a rigorous formulation musical contrasts is elusive. How can “traditional” and “popular” musics be broadly distinguished across genres, styles, and geocultural regions? Systematic sonic contrasts do not appear. Eschewing sound, I instead seek an answer in music’s social domain, centering my analysis on social networks linking fans to their preferred artists, i.e. in the social structure of fame. I hypothesize that, across musical styles and geographical regions, fan-artist networks characterizing “traditional” and “popular” musics exhibit contrastive degree distributions: quasi-normal (binomial) and centered at the mean (the “scale”) in traditional music; power law distributed (“scale-free”) in modern systems. It is well-established that selection based on an artist’s network degree (“fame”), a form of “preferential attachment” (rather than selection based on inherent attributes) leads to the formation of scale-free networks. In reality, preferential attachment is always combined with other factors (e.g. musical quality, musical affinity, cultural/linguistic comprehension, or geographical proximity).

    I speculate that preferential attachment is relatively weak for traditional types, since such attachment depends on network-level knowledge that is not readily available, while the absence of mass media sharply limits attachments’ geocultural range. I hypothesize that knowledge about artists—primarily transmitted orally—drops off as the inverse square of distance, while transportation, language, and musical style/culture inhibit musical flows as the inverse of distance, roughly speaking. Without mass media, music that is extremely popular in one location is not likely to be popular far away, even if preferential attachment continues to play a role. Subject to the above-mentioned restrictions, selections depend primarily on fans’ perceptions of artists’ audio-visual quality: fame is essentially aesthetic.

    By contrast, for popular types, distance plays a relatively small role in forming musical preferences, as global media (especially satellite TV and web) not only disseminate artists’ music in proportion to their fame, but also (by diffusing associated language and culture, e.g. English and hiphop) facilitate its broad receptivity. Further, driven by marketing considerations, global media diffuse not only musical information, but also tremendous quantities of meta-information about artists’ network degrees (and providing information, explicit or implicit, about popularity). As a consequence, preferential attachment predominates: fame is essentially social.

    In the absence of empirical data, this speculative theory is here experimentally tested via a computer simulation developed using the open-source statistical programming language R. A spherical surface (deployed to avoid edge effects and emulate global reality) is randomly populated by fans and artists according to a uniform distribution. All distances are computed along great circles. In each simulated time slice, each fan selects an artist at random, up to a maximum of 4 such selections (“old” artists being cycled out on a FIFO queue), as modulated by two global parameters: a weighting for preferential attachment applied to artist degree, set at 1 for traditional and 10 for popular; and an exponent implementing an inverse distance weighting, set at 5 for traditional, and 0 for popular. 500 iterations appear sufficient to achieve steady-state results, and simulations were run for traditional and popular cases. The resulting degree distributions turn out to be quasi-normal for traditional music, and quasi-scale-free for the popular. These theories and simulation results await confirmation by empirical data.

    Title
    Offensive Security with actual exploitation
    Time
    Thursday, 10:15-10:45
    Location
    Alts Bandai Onsen Hotel Conference Room
    Abstract
    Massive cyber attacks against Japanese government or companies have been increased day by day and reported frequently in the media. This fact means cyber attack is becoming more general also to ordinary people. However people with adequate knowledge to protect the system from various cyber attacks is still insufficient. In this presentation, we are going to focus on information security including attackers perspective and demonstrate what will actually happen when the system was compromised by an attacker.

    Title
    Survival Engineering
    Time
    Thursday, 12:00-13:00
    Location
    Alts Bandai Onsen Hotel Conference Room
    Abstract
    The lecture will address the use of resources in hardware/software projects. It will mention how resources have been used by mankind in the past, to develop environments to fit their needs for surviving on the earth or beyond, and how resources will be used in the future for the purpose of mankind’s surviving. It will argue the importance of survival engineering and how to acquire the skill of survival engineering. The lecture will refer to projects that Rob Oudendijk and Yuka Hayashi have done, as examples of survival engineering. The focus will be on learning how to look at a problem and how to solve it within constraints. “Survival Engineering” is the engineering ability to pursuit goals with limited resources. (“Survival Engineering” was named by Yasutomo Baba in 2012, and the idea has being developed by Rob Oudendijk and Yuka Hayashi.)
    Bio
    Rob Oudendijk is a self-taught engineer/designer/dancer/chef. To learn what he has done, Google him. Learning has been his most important skill. Born in Holland, he started learning from his mother, then learning from his family and nature, went to school to realize that nature could teach him just as much as the teachers could teach him. Having had the luxury of enjoying kindergarden for three years, he enjoyed elementary school and high school. After that, he was forced to "join" the army by the Dutch government. Having lived with mostly female around him (3 sisters, no brothers), he was thrown into a macho world. In the army, he prepared for a trip through Africa by himself. After having served for 1.5 year as an officer he worked for 6 month at a local garage to learn about car mechanics. He worked as a technician at a video production company and at night time he studied electronics at HTS (Amsterdam). He made his first CG for a theater play of a friend on a Commodore VIC-20 with poking and peeking direct into video memory and storing the CG on a modified cassette tape for which he himself built the electronics. After 4 months, he started to work for Montevideo a media house for video artists. In 1980, he went to New York to study modern dance at the Merce Cunningham Studio. At that time, to support himself financially, he worked for DCTV supporting video artists and designed/built professional video studios. He built customized video systems for discotheques. In the early 1985, he started to do beta testing for Avid and studied computer graphics by himself. In 1989, he came to Japan after having experienced Japanese culture in New York closely. He started to work for a small video post-production company by building customized video system for NHK productions. He also designed a speedup kit for Sony titling/graphics SMC3000G system that would speedup the computer by 6 times. He started a CG department inside the company and created many 3D computer graphics animation, mostly for medical companies. Around 2005, he started to do freelance for the Dutch Embassy to develop customized hardware and customized software. He also started to do freelance work for other commercial companies, such as DSM, Teijin, NEC, etc. Currently, he is CEO of YR-Design together with his partner, Yuka Hayashi. He just finished building a prototype cloud data center in Aizu in an abandoned school.

    Yuka Hayashi is a self-taught designer, from Japan. She graduated from Monterey Institute of International Studies, specializing in International Policy Studies with certification in Nonproliferation Studies (MA). She worked at a private think tank relevant to international policy as a research assistant. She also has an experience of working at a nonprofit organization promoting international cooperation. Currently, she is CEO of YR-Design together with her partner, Rob Oudendijk. She does design work, video shooting/editing, translation work, and IT assistant work together with their team member cat, Kitty-chan.

    Title
    Distributed Timestamping for Fun and Profit
    Time
    Thursday, 10:45-11:45
    Location
    Alts Bandai Onsen Hotel Conference Room
    Abstract
    Timestamping is the essential part of any system driven by "first come, first served" principle. Disputes about precedence are usually solved by some trusted third parties performing the role of timestamping servers. For example, in the domain name system, such role is performed by registrars in order to determine who was the first to register the domain name, in financial systems – by banks and coin mint (precedence of financial transactions and double spending), in auctions – by auctioneers (first bidder). In distributed systems such a role does not exist. In this survey the mechanisms of solving timestamping problem without a centralized entity will be discussed.
