Yung-Cheng Hsieh

President, National Taiwan University of Arts (臺灣藝術大學校長謝顒丞教授)

ABSTRACT

With the development of cultural industries in Taiwan in recent years, training creative talents and improving quality of creative industries has become an important issue for the government to tackle with. However, it still requires meticulous planning to create a proper environment for new talents and elevate creative industry to a new level. Universities serve as a vital link in education system for training personnel available for various professions, and students of art schools provide important personnel for future development of creative industry. In order to secure such valuable human assets, universities have to maintain an impeccable training environment which incorporates talents training, industry merging, and sustainable

management in order to conduct industrial clustering and expand domestic and international markets by through university.

ABSTRACT

Conventional semiconductor optical amplifiers (SOAs) have around 30 nm of bandwidth in the optical-communication spectral range. This spectral is much narrower than the available window of optical fiber, which covers from around 1300 nm to 1600 nm. As a result, the tunable semiconductor lasers using SOAs only give around 30 nm tuning range. Here we apply multiple quantum wells (MQWs) of different widths and different compositions to extend the spectral bandwidth. Although each well has only about 30 nm of bandwidth, as we stack them together and properly design each central wavelength, we are able to achieve broad bandwidth. On the other hand, the carrier distribution among those MQWs is not generally uniform. To achieve the uniform carrier distribution for broadband purpose, carrier dynamics is also important. In this presentation, we will discuss the design of MQWs and carrier dynamics therein to achieve broadband emission bandwidth that covers nearly from 1300 nm to 1600 nm. The tunable semiconductor lasers using such SOAs have given the record tuning range as large as 275 nm and tunable dual wavelengths with record spectral separation range from a few nm to 190 nm are achieved. Also, simultaneous generation of 8 channels with approximately 20 nm channel spacing, spanning from 1367 nm to 1527 nm is demonstrated.

ABSTRACT

A novel bidirectional lightwave transport system employing phase modulation (PM) scheme and light injection-locked distributed feedback laser diode (DFB LD) as a duplex transceiver for passive optical network (PON); as well as employing laser pointer lasers (LPLs) with directly modulating data signals for wavelength-division-multiplexing (WDM) visible light communication (VLC) is proposed and experimentally demonstrated. Impressive and low bit error rate (BER) operation is achieved for PON integration with VLC application. Such bidirectional PON integration with VLC system has been successfully demonstrated, which can not only present its advancement in PON/VLC application but also reveal its simplicity and convenience to be installed. Whereby, our proposed system is suitably applicable to the PON in combination with VLC system in wire and wireless transmission.

ABSTRACT

Nitride semiconductors (GaN, AlN, InN) exhibit many unique properties typically not found in silicon or other III-V semiconductors. They possess a large bandgap that can easily access visible and ultraviolet wavelengths. Their exciton binding energies are at least one order of magnitude larger than that in GaAs or InP. Their strained heterostructures exhibit a very large and anisotropic piezoelectric field. Some of these properties have enabled important applications in LEDs and power electronics. Some have presented challenges to the device performance. Some have not been fully exploited. In this work, we investigated the above properties in nitride semiconductor nanostructures including quantum dots, dot-in-wire structures, and plasmonic structures. We found that these nanostructures can fully harness the unique properties of nitride semiconductors and potentially lead to new applications in quantum cryptography and displays.

ABSTRACT

Intact perception and experience of emotion is vital for communication in the social environment. Emotion recognition is the ability to identify what you are feeling from moment to moment and to understand the connection between your feelings and your verbal/non-verbal expressions. When you are aware of your emotions, you can think clearly and creatively; manage stress and challenges; communicate well with others; and display trust, empathy, and confidence. Technologies for processing daily activities including facial expression, speech and language have expanded the interaction modalities between humans and computer-supported communicational artifacts, such as robots, iPAD, and mobile phones. In this talk, I will present theoretical and practical work offering new and broad views of the latest research in emotion recognition from multimedia information including facial expression, speech and language. I will talk about several parts spanning a variety of theoretical background and applications ranging from salient emotional features, emotional-cognitive model, to emotional information processing on these modalities.

UbiTablet: A Portable Camera-Projector System To Transform Any Flat

Surface Into A Touchable Display

ABSTRACT

After the concept of Tangible User Interface (TUI) was presented in 1997, different user interfaces intending to directly and seamlessly communicate information with physical environment are proposed over the years. Among them, only Camera-Projector System(CPS) actually goes to the market. The most well-known CPS product is Microsoft Surface Table. However, the traditional CPS researches require a fixed location, an expensive camera and projectors peripheral to hinder its popularity. Although Microsoft proposed a mobile version of CPS in 2005, their solution had many restrictions and did not support multiple hand gesture operation.

The research of CPS for TUI can be broadly classified into two categories: hand/object recognition and gesture inference. The previous studies mostly focused on hand/object recognition and supported simple finger touch reasoning only. In order to enable the CPS to become a practical TUI, gesture inference is very important and is tightly related to the

mechanism of hand recognition. Furthermore, the issue of one hand blocking the image of the other hand during multiple gesture operation is a major problem of hand recognition as well as gesture inference.

The talk presents a true portable version of CPS system, called UbiTablet, that can transform any flat surface into a touchable display. UbiTablet uses a pico projector to project the computer display onto the flat surface, and an infrared webcam to capture user’s hand gestures on the projected computer display.

This talk will discuss the approach of hand recognition and multiple hand gesture inference adopted by UbiTablet. The solution to the obstacle issue of multiple hand gestures will be explored also. Different from the previous CPS researches, UbiTablet allows users to arbitrarily place it on the desk and begin to manipulate the projected computer display with multi-touch gestures immediately.

BIOGRAPHY

ABSTRACT

The class of popular Internet live event such as sports games broadcast service can greatly benefit from the cloud technology employing resource pooling and rapid elasticity in resource allocation and management. Their external demands tend to be unpredictable and exhibit high degree of burstability. To sustain good viewing experience to the users, an important QoS support for this class of applications is the peak load management in the presence of

unpredictable demand. It relies on a close grasp of the demand behavior characteristics and accurate prediction model of it. In this work, we firsts analyze live sports event broadcast service workloads from a commercial Internet service provider. Our results show that popularity follows a 2-mode Zipf distribution. We observe some significant characteristics of the demand behavior. The demand behavior may differ significantly between games. Popular events tend to exhibit high varying behaviors in time, volume and the change rate during the course. And, the demand variation highly correlates with certain event-specific time points. To address the problem, we propose a learning-based temporal behavior profiling model and a run-time prediction algorithm to support accurate forecast of the external demand for Internet live event broadcast service. This work is of fundamental importance in the design, operations and evaluation of Internet content delivery systems. The results show that our proposed model and method can well capture the dynamics and unpredictability of the workload to provide advantageous support for accurate demand prediction in application performance management.

ABSTRACT

Communication distance limitation has been eliminated by the outstanding technology provided by the mobile communication or portable communication systems (PCSs). With the development of many kinds of mobile devices, such as smart phones, PDAs and mobile tablets, the mobile payment issue has been highly noticed and discussed in the near future. Since the resource constraint is needed for the lightweight mobile devices, to balance the efficiency and security is a challenge to the practice of e-commerce

applications in the mobile communication environment.

Roaming service provides an extension of the connectivity for a mobile user who is in the foreign area different from his register location. The agent of the foreign area (or called visitor location register, VLR) has no enough information to directly identify the mobile user, and further may be untrusted. In this situation, the security considerations such as authentication, anonymity, privacy and confidentiality should be paid more attention to and some secure e-commerce protocols for roaming also should be developed.

This talk introduces two kinds of solutions in roaming payment to avoid some malicious attacks such as repudiation, linkability and denial of service (DoS), and decrease the

communication costs by using delegation and group signatures. The proposed payment system can support the functionalities of multiple-vendors and small amounts of money by adopting the unbalanced one-way binary tree (UOBT) and PayWord-based micropayments. Moreover, both anonymity and untraceability can also be achieved to avoid privacy disclosure in the roaming payment environment.

ABSTRACT

Data mining is the technique of analyzing data to discover implicit information in large databases. Recent years it has shown its great promise in wide fields, such as business, advertising, bioinformatics, network analysis, to name a few. Nowadays, the rise of cloud computing even allows everyone to take the advantages of data mining by outsourcing. Data privacy, however, is always a concern in outsourcing. How to find the balance between data privacy and the accuracy of mining results thus attracts a lot of attention.

This talk focuses on the outsourcing of frequent itemset mining, which is to discover what patterns usually happen together from large databases. The risk of outsourcing frequent itemset mining to cloud environments is that everyone, including the mining service provider, could be a malicious data hacker. These hackers may even possess some domain knowledge regarding the outsourced data. The talk first discusses the challenges of secured outsourcing of frequent itemset mining, and presents a protecting model for this problem afterward. The protecting model can limit the probability of privacy leaks with moderate storage overhead.

ABSTRACT

Machinima is the use of real-time computer graphics engines to create a cinematic production. Most often, video games are used to generate the computer animation. My interest and creations in the virtual world has a main focus of bringing ancient Chinese culture through New Media platforms. In this paper, I will present two to three main types of Machinimas, and within each type a range of graphic inventiveness and specific purpose for various audiences. The First is an online Virtual World Platform, Secondlife - which has no predetermined gaming elements, it has a blank volume for users to create their world. It provides storage and the Graphic Engine itself with building tools and scripts - in real time. The Second type would be the artistic deployment of Video Game engines to record the graphic display as films. This would include regular game play and also creative, inventive use of the characters in the game platform as "talents" in the film.

I begin first with a Machinima documentary film of the functional aspects of a Virtual World. This demonstrates why for certain real life problems, a Virtual World is a breakthrough and proven to be useful in a unique way which is not possible with other forms of solutions.

Then, I will present the various types of artistic Machinimas, for animation film making and esthetic enjoyment purpose.

Lastly, I will show the current state of Machinima in the economic-business world and the applications of computer animation using video games graphics for commercial purpose.

電影的奇觀想像－奇觀電影和 S3D 立體電影

Chi-Fang Ting

Assistant Professor, Department of Motion Picture National Taiwan University of Arts

(臺灣藝術大學電影學系丁祈方教授)

ABSTRACT

電影本質上從來沒有脫離對於視覺奇觀的展現意圖，這種奇觀化原則更是成為當前電影創作或訴求的重要特徵，因此視覺性奇觀也為電影敘事媒介所特有的一種美學表現形態。電影中的奇觀不僅是一種視聽感受，更是一種心理體驗，也造成了形式上一定的意義，因為電影中透過影像(聲音)，以情感能量刺激觀眾。電影的奇觀特性在商業性和藝術性上，對於奇觀的文本特性是相同的。在形式美上，電影奇觀文本的視覺核心就是創造視覺快感，而且必須是非傳統常態電影的那種快感，是一種極端的，帶有碎片化的感觀刺激。當前電影中的奇觀，多經由數位技術所輔助或生成，更是把想像的框架超越了現實，實現在現實無法呈現的想像基礎上。在當代奇觀電影作為一種主要的電影形式，已經越來越多地反映出視覺文化的轉向以及景觀社會的特點。電影提供了允許觀眾在想像中對影像中的人或物發洩或延伸我們的本能情緒。基本上，這種環境是電影的科技力量所建構出來的。另外，S3D 電影所創建的奇觀，也是在歷經了 1950、1980 等二次短暫的發展，因為無法突破的技術之限制而沒落。進展到 2009 年時越趨純熟的數位技術，讓電影的視覺文化進入到了 3D 元年。S3D 影像的完成想像端靠著正負視差來完成，也因為這種正負視差的調整和控制，呼應了電影作者所想要創造的敘事空間的內在關係。但是電影的特效通常也都存在有噱頭的意味，使得眾多電影作家重新反思使用 S3D 電影的本意。本文將在電影的奇觀特性上的潮流，梳理國內外電影在視覺奇觀上的轉變風向，並以幾部重要的 S3D 電影來歸納其立體影像的表現特性，嘗試找出奇觀電影和 S3D 電影的現代意義，以供為電影創作上的參考方向。關鍵字: 奇觀、電影奇觀、S3D 立體電影

ABSTRACT

In this talk, we address several works around digital performance. We review motioncapturebased performances such as Merce Cunningham’s BIPED, Bill T. Jones’ Ghostcatching, as well as kinectbased performances. Some projects concerning recording or notating choreography are introduced as well. Inspired by EtienneJules Marey’s fluids photography, we are interested in making details visible by using new technologies with apt visualization. In the recent work, we are focusing on the relationships between body temperature and dance movement. At the first level, human body temperature is observed with help of infrared camera. At the second level, applying information visualization methods to thermal images facilitates understanding of both largescale and smallscale features of dance movement. By means of an appropriate visualization, we expect that dancer’s body state may emerge in accordance with body temperature. Furthermore, we are interested in perceiving a current of body temperature. We initiate fluid simulation according to thermal conditions creatively without boundary of physical body. In other words, physical body becomes liquefiable in coordination with the distribution of body temperature. We describe our technical schema and artistic concept to debate whether fluid/deformable/morphed figure can help to perceive both movement and body state.

ABSTRACT

Recently, there has been a fast-growing demand for multi-service technology in wireless communication systems. In the system, a multi-band bandpass filter (BPF) served in the radio frequency (RF) front end is required to remove unwanted frequencies and to obtain the desired signals. The major challenge of the BPFs is large in size as one of the passive devices in the circuit. Several building blocks such as ring resonator, uniform impedance resonator (UIR), defected ground structure (DGS), crossed resonator, stepped impedance resonator (SIR) and stub-loaded resonator (SLR) are popular for the design of compact multi-band BPFs.

In this talk, we introduce a simple method using SIRs to design several compact BPFs. Two coupled half-wavelength SIRs and tapped input/output lines are used to implement a BPF with multispurious suppression. By using the SIRs in the multilayered structure, a dual-band BPF having wide and narrow bands simultaneously is obtained. For the first time, a compact tri-band BPF is constructed by two direct-coupled SIRs with open stubs. The simulated results of those BPFs as well as the experimental ones are also included.

ABSTRACT

This talk introduces an approach, called generic job-level search, to leverage the programs which are already written and encapsulated as jobs. The programs can be game-playing programs in the computer game applications or search programs in optimization and machine learning applications. Such an approach is well suited to a distributed computing environment, since these jobs are allowed to be run by remote processors independently.

In this talk, we present and focus on a Job-Level Proof Number Search (JL-PNS), a kind of generic job-level search for solving computer game search problems, and apply JL-PNS to solving automatically several Connect6 positions including some difficult openings. This talk also presents a method of postponed sibling generation to generate nodes smoothly, and some policies, such as virtual-win, virtual-loss, virtual-equivalence, flagging, or hybrids of the above, to expand the nodes. Our experiment compared these policies and the results showed that the virtual-equivalence policy, together with flagging, performed the best against other policies. Finally, this talk also presents the prospective applications based on this technology.
