Presentation by Prof. Ashutosh Sabharwal: On Achieving Local View Capacity Via Maximal Independent Graph Scheduling
Abstract:
"If we know more, we can achieve more." This adage also applies to networks, where more information about the network state translates into higher sum-rates. In this talk, we formalize this increase of sum-rate with increased knowledge of the network state. The knowledge of network state is measured in terms of the number of hops of information available to each node and is labeled each node's local view. To understand how much capacity is lost due to limited information, we propose to use the metric of normalized sum-capacity, which is the h-hop local view sum-capacity divided by global-view sum-capacity. For the cases of one and two-local view, we characterize the normalized sum-capacity for many classes of deterministic and Gaussian interference networks. In many cases, a scheduling scheme called maximal independent graph scheduling is shown to achieve normalized sum-capacity. We also show that its generalization for one-hop local view, labeled coded maximal independent set scheduling, achieves capacity whenever its uncoded counterpart fails to do so.

Seminar by Prof. Bing Sheu: 21st Century Youth to Foresee the Future-Master Innovation
Time: 13:30–15:20
Location: Eng. Building IV, R117
Abstract:
此次演講，是依循「資訊革命的啟示與再思考」，去構想如何從電機、資訊的學科裡來萃取『軟體幹細胞』以便增強人們的腦力，來應付21世紀的挑戰？全部演講裡不包含任何方程式、或者數據，完全是極高等級的腦力激盪。一方面是沿著講者近幾年來多次演講的深入演進，另一方面是因應美國史丹福大學電機系Boris Murmann莫面教授邀請下次前往演講、特別指明要加上此一多元方向。
　演講裡我們會探討：逆境商數 (Adversity Quotient)，人造智慧 (與技術的) 累進論，生命的新意涵，人才的未來挑戰與在業界要成功的五大基本功，還有如何善用『未來』？
大學 (University) 就是充滿希望的「宇宙城市」(Universe + City)！我們會探討為什麼「電機博士」在西方要稱作Ph.D. in EE，Doctor of Philosophy in Electrical Engineering？在此，『哲學』要發揮什麼樣的關鍵角色？這和「軟體幹細胞」又如何銜接起來？
接著，會從英文的關鍵字、還有「電子學」、「通訊、與信號處理課程」去詳細舉例。『聯合圖像專家小組』(JPEG、Joint Photographic Experts Group) 的『離散餘弦轉換』與兩千年來佛學裡提到的：『見山是山、見水是水』有何關連？全面最佳化 (Global Optimization)和「靈光一閃、突然開竅」又是如何拉在一起的？
　在21世紀，每一個人最重要的，是「知道自己的定位」。更重要的，是深刻地體會到自己『適度』的努力，可以調整與改變個人的定位。本演講可以提供聽眾們一個有系統的工具包　(Tool Kit)。

Presentation by Prof. Aki Nishihara: Filter Banks for Speech Processing
Time: 13:30–15:20
Location: International Seminar Hall at B1 of Engineering Building V
Abstract:
Perfect reconstruction filter banks have been analyzed, designed, and implemented. In speech communication, however, phase distortion can be tolerated to some extent, because human ears can understand the speech even with phase distortion. In that case we may use IIR filters to construct filter banks. IIR filters are known to be more efficient than FIR filters in computational complexity. A design method of alias-free and amplitude-distortion-free IIR filter banks is presented. The transfer functions to be realized must be power symmetric. The filter bank structures are obtained by successive extraction of wave digital lattice sections utilizing paraunitarity of the transfer matrix. The resultant structures are efficient in terms of computational complexity and sensitivities. Synthesis banks are readily obtained by designing analysis banks.

Presentation by Prof. Yung-Hsiang Lu from the ECE Purdue University: Establishing Trust and Saving Energy in Computation Offloading
Abstract: Handheld mobile devices (such as phones and PDAs) have become primary computing platforms. These devices have limited battery energy, processor performance, and memory. Meanwhile, wireless networks are widely available and allow the mobile devices to connect to high-performance grid-powered servers. These mobile devices may send complex computation to the servers for better performance and lower energy consumption. This is called computation offloading. The servers may charge the mobile devices' users for the services. The mobile devices have to trust the computation results from the servers. However, it is possible that the servers return random results and still charge the users.
This presentation will explain some recently developed techniques for mobile devices to detect whether severs have indeed performed the computation as claimed. We instrument the offloaded programs and embed additional information as checkpoints that are executed at the servers. When the results are returned from the severs, the mobile devices compare the values of the checkpoints to determine whether the servers have executed the offloaded programs. We evaluate the trade-offs between confidence and overhead in performance and mobile devices' energy consumption.

Presentation by Prof. Chien-Chung Shen from the University of Delaware: Underwater Networks: Challenges and Solutions
Abstract: Oceans together with lakes and rivers cover more than 70% of the Earth, nurturing countless marine life, reserving huge amount of natural resources, and dominating Earth's overall climate. It is to human's best interest to monitor and act upon the well-being of these marine environments, and underwater wireless networks have emerged as the primary tools to achieve such goals. In this talk, I will describe new issues and challenges introduced by underwater networks, and describe solutions of MAC, localization, routing, and swarming protocols.
