The reliability of infrastructure software, such as operating systems and web servers, is often hampered by the mismanagement of resources, such as memory and network connections. The Vault programming language allows a programmer to describe resource management protocols that the compiler can statically enforce. Such a protocol can specify that operations must be performed in a certain order and that certain operations must be performed before accessing a given data object. Furthermore, Vault enforces statically that resources cannot be leaked. We validate the utility of our approach by enforcing protocols present in the interface between the Windows 2000 kernel and its device drivers.

Software engineers often use high-level models (for instance, box and arrow sketches) to reason and communicate about an existing software system. One problem with high-level models is that they are almost always inaccurate with respect to the system's source code. We have developed

. Tracking research has diverged into two camps; low-level approaches which are typically fast and robust but provide little fine-scale information, and high-level approaches which track complex deformations in high-dimensional spaces but must trade off speed against robustness. Real-time high-level

SUMMARY In this paper we report exploratory analyses of high-density oligonucleotide array data from the Affymetrix GeneChip R system with the objective of improving upon currently used measures of gene expression. Our analyses make use of three data sets: a small experimental study consisting

We show a learning-based method for low-level vision problems. We set-up a Markov network of patches of the image and the underlying scene. A factorization approximation allows us to easily learn the parameters of the Markov network from synthetic examples of image/scene pairs, and to e ciently

traffic modeling assumptions. In this paper, we provide a plausible physical explanation for the occurrence of self-similarity in LAN traffic. Our explanation is based on new convergence results for processes that exhibit high variability (i.e., infinite variance) and is supported by detailed statistical

method for high-level system design and analysis and survey some of its application highlights in industrial software-based system engineering. We illustrate the method by defining models for three simple control systems (sluice gate, traffic light, package router) and by characterizing Event

We propose a method of constructing concurrent programs in which the synchroni-zation skeleton of the program ~s automatically synthesized from a high-level (branching time) Temporal Logic specification. The synchronization skeleton is an abstraction of the actual program where detail irrelevant

... a compiler framework designed to support transparent, lifelong program analysis and transformation for arbitrary programs, by providing high-level information to compiler transformations at compile-time, link-time, run-time, and in idle time between runs. LLVM defines a common, low-level code
