We study several classes of related scheduling problems including the carpool problem, its generalization to arbitrary inputs and the chairman assignment problem. We derive both lower and upper bounds for online algorithms solving these problems. We show that the greedy algorithm is optimal among online algorithms for the chairman assignment ...

As an efficient distribution mechanism, Peer-to-Peer (P2P) technology has become a tremendously attractive solution to offload servers in large-scale video streaming applications. However, in providing on-demand asynchronous streaming services, P2P streaming design faces two major challenges: how to schedule efficient video sharing between peers with asynchronous playback progresses? how to ...

Compared with the traditional client/server streaming model, peer-assisted video streaming has been shown to provide better scalability with lower infrastructure cost. In this paper, we describe how peer-assisted video streaming can be implemented through real-time service oriented architecture. Our architecture, dubbed PACTS, is composed of 5 distinct service components: directory ...

Automating the transistor and wire-sizing process is an important step toward being able to rapidly design high-performance, custom circuits. This paper presents a circuit optimization tool that automates the tuning task by means of state-of-the-art nonlinear optimization. It makes use of a fast circuit simulator and a general-purpose nonlinear optimization ...

We consider the fundamentals of a mathematical framework for decentralized optimization and dynamic optimal control in autonomic computing systems that provide self-* properties. In particular, we first study conditions under which decentralized optimization can provide the same quality of solution as centralized optimization. After establishing such equivalence results under mild ...

Recently, a number of authentication schemes have been proposed for multimedia data. The main requirement for such authentication systems is that minor modifications which do not alter the content of the data preserve the authenticity of the data, whereas modifications which do modify the content render the data not authentic. ...

We present image data hiding and authentication schemes based on halftoning and coordinate projection. The proposed data hiding scheme can embed images of the same size and similar bit depth into the cover image and robustness against compression is demonstrated. The image authentication scheme is based on the data hiding ...
Keywords: tamper detection, authentication, digital halftoning, error diffusion, self-repairing images, coordinate projection, data hiding

Full text available: PDFPDF
The circuit tuning problem is best approached by means of gradient-based nonlinear optimization algorithms. For large circuits, gradient computation can be the bottleneck in the optimization procedure. Traditionally, when the number of measurements is large relative to the number of tunable parameters, the direct method is used to repeatedly solve ...
