Receiver-driven Layered Multicast
, 1996
"... State of the art, real-time, rate-adaptive, multimedia applications adjust their transmission rate to match the available network capacity. Unfortunately, this source-based rate-adaptation performs poorly in a heterogeneous multicast environment because there is no single target rate — the conflicti ..."

— the conflicting bandwidth requirements of all receivers cannot be simultaneously satisfied with one transmission rate. If the burden of rate-adaption is moved from the source to the receivers, heterogeneity is accommodated. One approach to receiver-driven adaptation is to combine a layered source coding algorithm
Quantization Index Modulation: A Class of Provably Good Methods for Digital Watermarking and Information Embedding
- IEEE TRANS. ON INFORMATION THEORY
, 1999
"... We consider the problem of embedding one signal (e.g., a digital watermark), within another "host" signal to form a third, "composite" signal. The embedding is designed to achieve efficient tradeoffs among the three conflicting goals of maximizing information-embedding rate, mini ..."

On the Placement of Web Server Replicas
- In Proceedings of IEEE INFOCOM
, 2001
"... Abstract—Recently there has been an increasing deployment of content distribution networks (CDNs) that offer hosting services to Web content providers. CDNs deploy a set of servers distributed throughout the Internet and replicate provider content across these servers for better performance and avai ..."

server replicas to further improve CDN performance. In this paper, we explore the problem of Web server replica placement in detail. We develop several placement algorithms that use workload information, such as client latency and request rates, to make informed placement decisions. We then evaluate
Law, Finance and Firm Growth
- Journal of Finance
, 1998
"... We investigate how differences in legal and financial systems affect firms' use of external financing to fund growth. We show that in countries whose legal systems score high on an efficiency index, a greater proportion of firms use long-term external financing. An active, though not necessaril ..."

not necessarily large, stock market and a large banking sector are also associated with externally financed firm growth. The increased reliance on external financing occurs in part because established firms in countries with well-functioning institutions have lower profit rates. Government subsidies to industry
An analysis of database workload performance on simultaneous multithreaded processors
- In Proceedings of the 25th Annual International Symposium on Computer Architecture
, 1998
"... Simultaneous multithreading (SMT) is an architectural technique in which the processor issues multiple instructions from multiple threads each cycle. While SMT has been shown to be effective on scientific workloads, its performance on database systems is still an open question. In particular, databa ..."

Continuous Profiling: Where Have All the Cycles Gone
- ACM TRANSACTIONS ON COMPUTER SYSTEMS
, 1997
"... This paper describes the DIGITAL Continuous Profiling Infrastructure, a sampling-based profiling system designed to run continuously on production systems. The system supports multiprocessors, works on unmodified executables, and collects profiles for entire systems, including user programs, shared ..."

libraries, and the operating system kernel. Samples are collected at a high rate (over 5200 samples/sec per 333-MHz processor), yet with low overhead (1–3 % slowdown for most workloads). Analysis tools supplied with the profiling system use the sample data to produce a precise and accurate accounting, down
Adaptive Filters for Continuous Queries over Distributed Data Streams
- In SIGMOD
, 2003
"... We consider an environment where distributed data sources continuously stream updates to a centralized processor that monitors continuous queries over the distributed data. Significant communication overhead is incurred in the presence of rapid update streams, and we propose a new technique fo ..."

High Speed Switch Scheduling for Local Area Networks
- ACM Transactions on Computer Systems
, 1993
"... Current technology trends make it possible to build communication networks that can support high performance distributed computing. This paper describes issues in the design of a prototype switch for an arbitrary topology point-to-point network with link speeds of up to one gigabit per second. The s ..."

. The switch deals in fixed-length ATM-style cells, which it can process at a rate of 37 million cells per second. It provides high bandwidth and low latency for datagram traffic. In addition, it supports real-time traffic by providing bandwidth reservations with guaranteed latency bounds. The key
McRT-STM: a High Performance Software Transactional Memory System for a Multi-Core Runtime
- In Proc. of the 11th ACM Symp. on Principles and Practice of Parallel Programming

"... Applications need to become more concurrent to take advantage of the increased computational power provided by chip level multiprocessing. Programmers have traditionally managed this concurrency using locks (mutex based synchronization). Unfortunately, lock based synchronization often leads to deadl ..."

Power management in energy harvesting sensor networks
- Networked and Embedded Systems Laboratory, UCLA
, 2006

Power management is an important concern in sensor networks, because a tethered energy in-frastructure is usually not available and an obvious concern is to use the available battery energy efficiently. However, in some of the sensor networking applications, an additional facility is available to am ..."

Certain considerations in using an energy harvesting source are fundamentally different from that in using a battery, be-cause, rather than a limit on the maximum energy, it has a limit on the maximum rate at which the energy can be used
