101 Silva, Claudio T.ISP: An optimal out-of-core image-set processing streaming architecture for parallel heterogeneous systemsImage population analysis is the class of statistical methods that plays a central role in understanding the development, evolution, and disease of a population. However, these techniques often require excessive computational power and memory that are compounded with a large number of volumetric inp...2012-01-01
102 Susarla, Sai R.; Carter, JohnKhazana: a flexible wide area data storeKhazana is a peer-to-peer data service that supports efficient sharing and aggressive caching of mutable data across the wide area while giving clients significant control over replica divergence. Previous work on wide-area replicated services focussed on at most two of the following three proper...Khazana; Peer-to-peer data service2003-10-13
103 Susarla, Sai R.; Carter, JohnMiddleware support for locality-aware wide area replicationCoherent wide-area data caching can improve the scalability and responsiveness of distributed services such as wide-area file access, database and directory services, and content distribution.

104 Kasera, Sneha K.; Patwari, NealHigh-rate uncorrelated bit extraction for shared secret key generation from channel measurementsSecret keys can be generated and shared between two wireless nodes by measuring and encoding radio channel characteristics without ever revealing the secret key to an eavesdropper at a third location. This paper addresses bit extraction, i.e., the extraction of secret key bits from noisy radio chan...Wireless networks; Multipath fading; Physical layer; Key generation; Secret keys; Bit extraction2010-01
105 Berzins, MartinInvestigating applications portability with the Uintah DAG-based runtime system on PetaScale supercomputersPresent trends in high performance computing present formidable challenges for applications code using multicore nodes possibly with accelerators and/or co-processors and reduced memory while still attaining scalability.

106 Venkatasubramanian, SureshMultiple target tracking with RF sensor networksRF sensor networks are wireless networks that can localize and track people (or targets) without needing them to carry or wear any electronic device. They use the change in the received signal strength (RSS) of the links due to the movements of people to infer their locations. In this paper, we cons...2014-01-01
107 Organick, Elliott I.Semiannual technical report transformation of ADA programs into silicon (1 Sept. 1981- 28 Feb. 1982)This report summarizes the first six months work of the research project, "Transformation of Ada Programs into Silicon."

108 Kirby, Robert MichaelVerifying volume rendering using discretization error analysisWe propose an approach for verification of volume rendering correctness based on an analysis of the volume rendering integral, the basis of most DVR algorithms. With respect to the most common discretization of this continuous model (Riemann summation), we make assumptions about the impact of parame...2014-01-01
109 Fujimoto, Richard M.A shared memory algorithm and proof for the alternative construct in CSPCommunicating Sequential Processes (CSP) is a paradigm for communication and synchronization among distributed processes. The alternative construct is a key feature of CSP that allows nondeterministic selection of one among several possible communicants. Previous algorithms for this construct assume...Shared memory algorithm; Communicating Sequential Processes; CSP1987
110 Jacobson, Hans; Gopalakrishnan, GaneshApplication specific asynchronous microengines for efficient high-level controlDespite the growing interest in asynchronous circuits programmable asynchronous controllers based on the idea of microprogramming have not been actively pursued Since programmable control is widely used in many commercial ASICs to allow late correction of design errors to easily upgrade product f...Asynchronous microengines1997
111 Balasubramonian, RajeevDynamically tunable memory hierarchyThe widespread use of repeaters in long wires creates the possibility of dynamically sizing regular on-chip structures. We present a tunable cache and translation lookaside buffer (TLB) hierarchy that leverages repeater insertion to dynamically trade off size for speed and power consumption on a per...Microarchitecture; High performance microprocessors; Reconfigurable architectures; Energy and performance of on-chip caches; Translation lookaside buffer (TLB); Tunable cache2003-10
112 Zhang, LixinISIM: The simulator for the impulse adaptable memory systemThis document describes ISIM, the simulator for the Impulse Adaptable Memory System. Impulse adds two new features to a conventional memory system. First, it supports a configurable, extra level of address remapping at the memory controller. Second, it supports prefetching at the memory controller. ...ISIM; Impulse Adaptable Memory System; Memory systems1999
113 Kasera, Sneha K.On fast and accurate detection of unauthorized wireless access points using clock skewsWe explore the use of clock skew of a wireless local area network access point (AP) as its fingerprint to detect unauthorized APs quickly and accurately. The main goal behind using clock skews is to overcome one of the major limitations of existing solutions-the inability to effectively detect Mediu...Clock skews; Unauthorized access; Medium access control; MAC; Address spoofing; Wireless networks; Time Synchronization Function; TSF2010-03
