Experimental Analysis of Different Techniques for Bounded Model Checking Ricardo Medel, Stevens Institute of Technology Bounded Model Checking (BMC) is a procedure that searches for counterexamples for a given property in bounded executions of a non-terminating system. This paper compares the performance of SAT-based, BDD-based and explicit state based BMC on benchmarks drawn from commercial designs. Our experimental framework provides an uniform and comprehensive basis to evaluate each of these approaches based on a number of factors. Our results differ f

Web Server and Services Performance Portal: An example of a Real life Component Based Software Development Reza Peyrovian, AT&T Labs This presentation covers the software architecture of a performance management system that reports to it clients the health of the web servers and their applications along with the network metrics, such as alarms and thresholds on a web portal. The system reports on servers that are hosted on the Internet behind firewalls and millions of Internet users access them from around the globe for business and entertainment. This system was developed over a period of

Universal Re-encryption for Mixnets Markus Jakobsson, RSA Laboratories We introduce a new cryptographic technique that we call universal re-encryption. A conventional cryptosystem that permits re-encryption, such as ElGamal, does so only for a player with knowledge of the public key corresponding to a given ciphertext. In contrast, universal re-encryption may be performed without knowledge of public keys. We demonstrate an asymmetric cryptosystem with universal re-encryption that is half as efficient as standard ElGa

Statistical Methods for Real-time Video Surveillance Ramesh Visvanathan, Siemens Corporate Research The proliferation of cheap sensors and increased processing power has made real-time acquisition and processing of video information more feasible. Real-time video analysis tasks requiring object detection and tracking can increasingly be performed efficiently on standard PC's. Smart cameras are being designed that enable on-camera applications to directly output compressed data or meta-event information instead of raw video. These adv

CYCLONE: A Safe Dialect of C Trevor Jim, AT&T Labs - Research Cyclone is a dialect of C that is designed to be safe: free of buffer overflows, format string attacks, memory management errors, and other such bugs that are often the cause of security breaches. Cyclone retains C's syntax, types, and low-level control over data representations and memory management, while ensuring safety through a combination of compile-time analysis and link- and run-time checks. The combination of safety and C com

Algebraic confluence for some overlapping rewrite systems Eduardo Bonelli, Stevens Institute of Technology One of the main syntactical results in lambda calculus is confluence: every two diverging rewrite sequences (derivations) may be made to converge. It was introduced in the 30's to establish the consistency of lambda calculus as a theory. A stronger form of confluence was introduced by J-J.Levy in his 1978 PhD thesis: the algebraic theory of confluence. He establishes a notion of equivalence on derivations and shows that a

Visual Form, Art, Perception, and Image Transformations Doug DeCarlo, Rutgers University Each time we look at a picture, our visual system draws on the wealth of information there to infer what's going on in the scene. This process is guided by the structure of visual form: the intrinsic order and organization of natural imagery that manifests itself as visual cues such as contour, shading or texture. Artists implicitly draw upon this structure in a way that clarifies information and encourages specific interpretations; I'll show a

The Local Area pi Calculus Tom Chothia, Stevens Institute of Technology The Internet groups hosts into islands of local communication. It is the agreed conventions and shared knowledge that connect these islands, just as much as the switches and wires that run between them. For my PhD I developed a process calculus to capture this phenomenon. The local area pi calculus, an extension of the pi-calculus, allows a communication channel to have within its scope several, disjoint local areas. Such a c

The AVENUE Automated Site Modeling Project: Geometry and Texture Recovery of Scenes of Large Scale Peter Allen, Columbia University The AVENUE project's goal is to automate the site modeling process. The main component of AVENUE is a system for photo-realistic 3D model acquisition from the combination of range and image sensing. The input is a sequence of unregistered range scans of the scene and a sequence of unregistered 2-D photographs of the same scene. The output is a true texture-mapped geometric model of the scene. Segmentation algorithms simplify the dense data-sets and pr

Software Architecture for Component-Based Middleware Applications Virginia de Paula Component-based development is a current trend in software engineering mainly because it promises to concretize the idea of reusing existing components by plugging-and-playing them in order to compose an application. Frameworks for component interoperability are playing an important role in component-based application development because they offer support for working with heterogeneous components despite differences in language and in the execution platform. The CORBA model

The MD-Join: An Operator for Complex OLAP Samuel Kim, Stevens Institute of Technology OLAP queries (i.e., group-by or cube-by queries with aggregation) have proven to be valuable for data analysis and exploration. Many decision support applications need very complex OLAP queries, requiring a fine degree of control over both the group definition and the aggregates that are computed. For example, suppose that the user has access to a data cube whose measure attribute is Sum(Sales). Then the user might wish to compute the sum

Instrinsic Mappings between Implicit Surfaces Dr. H. Quynh Dinh ,Stevens Institute of Technology, Hoboken, NJ A mapping between two surfaces describes pairs of corresponding points on the two surfaces, where each pair consists of a point on one surface and a point on the second surface. Mappings have a variety of uses, including texture transfer, model simplification, multi-way morphing, and surface analysis. Given a four dimensional implicit function in 3D space and time that defines a transformation between two surfaces, we

Language-Based Information-Flow Security Andrei Sabelfeld, Cornell University Current standard security practices do not provide substantial assurance that the end-to-end behavior of a computing system satisfies important security policies such as confidentiality. An end-to-end confidentiality policy might assert that secret input data cannot be inferred by an attacker through the attacker's observations of system output; this policy regulates information flow. Conventional security mechanisms such as access contro

Tight Bounds for Shared Memory Systems Accessed by Byzantine Processes We provide efficient constructions and strong lower bounds for shared memory systems accessed by n processes, up to t of which may exhibit Byzantine faults, in a model previously explored by Malkhi et al. (DISC 2000). We show that sticky bits are universal in the Byzantine failure model provided n is at least 3t+1, an improvement over the previous result requiring n to be at least (2t+1)(t+1). Our result follows from a new strong consensus construction that uses sticky bits and tolerates t Byzantine

From Movies to 3D Models: the Structure-from-Motion Problem John Oliensis, NEC Research Institute I describe some of my recent results on Structure from Motion (SFM). SFM is the most studied problem in Computer Vision and the most robust way to make inferences about the 3D world from images. The problem is: given a sequence of photographic images of a fixed 3D scene, taken by a moving camera, estimate 1) a 3D geometric model of the scene (structure), 2) the camera's motion, i.e., its position and orientation for each image. Solving SFM will
