Abstract: Accountability implies that any entity should be held responsible for its own specific action or behavior so that the entity is part of larger chains of accountability. One of the goals of accountability is that once an event has transpired, the events that took place are traceable so that the causes can be determined afterward. The poor accountability provided by today's computers and networks wastes a great deal of money and effort. This is due to the simple fact that today's computing and network infrastructure was not built with accountability in mind. In this talk we introduce our previous work: accountable monitoring methodology called flow-net. We apply this methodology to many applications ranging from operating system design to computer networks.

Abstract: As a useful and practical object-oriented programming language, Java has been used in many practical systems including enterprise servers, smart phones, and embedded systems, due to its high safety and portability. Then, a lot of educational institutes such as universities and professional schools have offered Java programming courses to cultivate Java engineers. To assist Java programming educations, we have proposed and implemented a Web-based Java Programming Learning Assistant System called JPLAS. JPLAS offers four types of problems that have different difficulties to cover studies of students at different learning levels: 1) element fill-in-blank problem, 2) value trace problem, 3) statement fill-in-blank problem, and 4) code writing problem. For 1), we have proposed a graph-theory based algorithm to automatically generate element fill-in-blank problems that have unique correct answers. For 3) and 4), we have adopted the test-driven development (TDD) method so that the answer codes from students can be automatically verified using test codes for their self-studies. In this talk, we introduce the outline of JPLAS and its application results to the Java programming course in our department. Besides, we introduce some new features of JPLAS such as the offline answering function, the coding rule learning function, and the clone code deletion problem.

Abstract: In this talk, I will first review the notion of plastic architecture and end-to-end network slicing for next generation mobile networks (5G). Then my talk will be focused on Software Defined Protocol (SDP), as the key enabling technology for RAT slicing to facilitate a flexible service-oriented protocol stack deployment for 5G. SDP is designed to provide high-throughput, low-latency and elastic mobile services by making data-plane protocol programmable based on platform virtualization and functionality modularization. Next I will address one of the most important issues in SDP, namely SDP request mapping (SDPM). In SDPM, an SDP request (SDPR) is fulfilled by mapping the corresponding SDP function blocks and virtual links onto underlying SDP servers. We employ the LTE Layer-2 data-plane processing as a benchmark for validating the effectiveness of the SDP technique. Finally, I will elaborate a prototypye of 5G network slicing based on SDP and present experimental and simulation results for demonstrating the effectiveness and advantages of SDP technique in providing elastic low-latency mobile services.

Abstract: Recently, the issue of autonomous vehicles (AV) has drawn much research attention. The AVs need effective automatic navigation service to guide them to reach their destinations securely in the situation that there is no human driver. It is possible and feasible to take use of the infrastructure of vehicle ad hoc networks (VANET) to implement this objective. Although there are a lot of security solutions proposed to prevent various malicious attacks in VANETs, the performance issue of the VANETs has been ignored. The security solutions with complex security functions may cost much computation resource and incur a high authentication delay for not only the on-board unit (OBU) on vehicles but also the roadside units (RSUs), especially when the navigation service is involved. In this talk, I will address the security issues of the VANETs with an introduction of a lightweight secure VANET-based navigation scheme (LSVN) that has a lower computation cost and a lower authentication delay. By the LSVN, a vehicle firstly initiates the navigation service with a RSU nearby to request a shared symmetric key for later communication with other RSUs in the VANET. Then, the best route will be selected. The pseudo identity of the vehicle and the shared keying materials are sent to the RSUs on the route of the vehicle to its destination. At last, the vehicle will be led to its destination by these RSUs in series. The LSVN scheme has been formally verified by BAN Logic to provide the guarantee of the integrity of messages and mutual authentication of the communication parties. Performance analysis shows that the LSVN can minimize the use of asymmetric cryptographic operations and reduce the authentication delay comparing with an existing security scheme.

Abstract: Near-infrared spectroscopy (NIRS), as signal detecting and processing, has been used in medical imaging to obtain oxygenation and hemodynamic response in the cerebral cortex. As one of updated techniques, it has been evidenced useful, efficient, and effective in the medical examinations. It applied in cortical activation detection and functional connectivity in brain research. Despite some advances in functional lateralization, most of the studies have focused on the prefrontal cortex but little has been done to study the somatosensory region (S1). For this reason, the aim of our current study is to assess bilateral connectivity in the somatosensory region by using NIRS and noxious stimulation. A few healthy subjects were investigated using near-infrared spectroscopy during an acupuncture stimulation procedure to safely induce pain in subjects. A multiscale analysis based on wavelet transform coherence (WTC) was designed to assess the functional connectivity of corresponding channel pairs within the left and right S1 region. The distributions of the reactions based on WTC in the brain after the stimulations are presented by both time region and frequencies domain. The coherence in time-frequency domain between homologous signals generated by contralateral channel pairs increased during stimulation tasks but not during resting time. This study will contribute to the research field to investigate cerebral hemodynamic response of pain perception using NIRS.

Abstract: Image/video restyling as an expressive way for producing user-customized appearances has received much attention in creative media researches. In interactive design, it would be powerful to re-render the stylized presentation of interested objects virtually using computer-aided design tools for retexturing, especially in the image space with a single image or video as input. The nowaday retexturing methods mostly process texture distortion by inter-pixel distance manipulation in image space, the underlying texture distortion is always destroyed due to limitations like improper distortion caused by human mesh stretching, or unavoidable texture splitting caused by texture synthesis. In this talk, we focused the image/video restyling work on efficient retexturing and stylization. We present the interactive retexturing that preserves similar texture distortion without knowing the underlying geometry and lighting environment. We utilized SIFT corner features to naturally discover the underlying texture distortion. The gradient depth recovery and wrinkle stress optimization are applied to accomplish the distortion process. We facilitate the interactive retexturing via real-time bilateral grids and feature-guided distortion optimization using GPU-CUDA parallelism. Video retexturing is achieved through a keyframe-based texture transferring strategy using accurate TV-L1 optical flow with patch motion tracking techniques in real-time. Further, we work on GPU-based abstract stylization that preserves the fine structure in the original images using gradient optimization. We propose the image structure map to naturally distill the fine structure of the original images. Gradient-based tangent generation and tangent-guided morphology are applied to build the structure map. We facilitate the final stylization via parallel bilateral grids and structure-aware stylizing in real-time on GPU-CUDA. In the experiments, our proposed approaches consistently demonstrate high quality performance of image/video restyling in real-time using GPU parallelism. In the future, we will further extend the interactive retexturing to more complicated general video applications with large motion and occluded scene avoiding textures flicking. We will also work on new approaches to make video retexturing more stable by inspiration from latest video processing techniques.
