1 Mathews, V. John; Schlegel, ChristianA blind projection receiver for coded CDMA systemsABSTRACT This paper presents a blind adaptive CDMA receiver that requires no knowledge of the spreading codes, the delays, and the energy of the received signals associated with the interfering users. Our receiver is based on linear interference cancellation and adaptive interference signal subspa...1999
2 Zhang, LixinA comparison of online superpage promotion mechanismsThe amount of data that a typical translation lookaside buffer (TLB) can map has not kept pace with the growth in cache sizes and application footprints. As a result, the cost of handling TLB misses limits the performance of an increasing number of applications. The use of superpages, multiple adjac...Superpages; Translation lookaside buffer; TLB1999
3 Sloan, Peter-PikeA painterly approach to human skinRendering convincing human figures is one of the unsolved goals of computer graphics. Previous work has concentrated on modeling physics of human skin. We have taken a different approach. We are exploring techniques used by artists, specifically artists who paint air-brushed portraits. Our goal is t...Human skin1999
4 Tasdizen, TolgaAlgebraic curves that work betterAn algebraic curve is defined as the zero set of a polynomial in two variables. Algebraic curves are practical for modeling shapes much more complicated than conics or superquadrics. The main drawback in representing shapes by algebraic curves has been the lack of repeatability in fitting algebraic...1999
5 Myers, Chris J.Architectural synthesis of timed asynchronous systemsThis paper describes a new method for architectural synthesis of timed asynchronous systems. Due to the variable delays associated with asynchronous resources, implicit schedules are created by the addition of supplementary constraints between resources. Since the number of schedules grows exponenti...1999
6 Riloff, Ellen M.Bootstrapping for text learning tasksWhen applying text learning algorithms to complex tasks, it is tedious and expensive to hand-label the large amounts of training data necessary for good performance. This paper presents bootstrapping as an alternative approach to learning from large sets of labeled data. Instead of a large quantity ...Bootstrapping; Text learning algorithms; Seed information1999
7 Stevens, KennethCAD directions for high performance asynchronous circuitsThis paper describes a novel methodology for high performance asynchronous design based on timed circuits and on CAD support for their synthesis using Relative Timing. This methodology was developed for a prototype iA32 instruction length decoding and steering unit called RAPPID ("Revolving Asynchro...1999
8 Smith, Grant D.Conformational properties of poly(vinylidene fluoride). A quantum chemistry study of model compoundsThe molecular geometries and conformational energies of model molecules of poly(vinylidene fluoride) (PVDF) have been determined from high-level quantum chemistry calculations and have been used in parametrization of a six-state rotational isomeric state (RIS) model for PVDF. The model molecules inv...Poly(vinylidene fluoride); PVDF; Conformational properties1999
9 Riloff, Ellen M.Corpus-based identification of non-anaphoric noun phrasesCoreference resolution involves finding antecedents for anaphoric discourse entities, such as definite noun phrases. But many definite noun phrases are not anaphoric because their meaning can be understood from general world knowledge (e.g., "the White House" or "the news media"). We have develope...Corpus-based identification; Non-anaphoric noun phrases; Coreference resolution; MUC-4; Discourse entity; DE1999
10 Jacobson, HansDesign and validation of a simultaneous multi-threaded DLX processorModern day computer systems rely on two forms of parallelism to achieve high performance, parallelism between individual instructions of a program (ILP) and parallelism between individual threads (TLP). Superscalar processors exploit ILP by issuing several instructions per clock, and multiprocessors...DLX processor; Validation1999
11 Carter, John B.Design of a parallel vector access unit for SDRAM memory systemsParallel Vector Access is a technique that exploits the regularity of vector or stream accesses to perform them efficiently in parallel on a multi-bank memory system. The performance of applications that have vector accesses may be improved using a memory controller that performs scatter/gather oper...Parallel vector access; SDRAM memory; Multi-bank memory system1999
12 Freier, Rodney; Thompson, William B.Design-space exploration of most-recent-only communication using myrinet on SGI ccNUMA architecturesSGI's current ccNUMA multiprocessor architectures offer high scalability and performance without sacrificing the ease of use of simpler SMP systems. Although these systems also provide a standard PCI expansion bus, the bridging between PCI and SGI's ccNUMA architecture invalidates the assumptions ty...Most-recent-only communication; Myrinet; SGI; Communications latencies1999
13 Myers, Chris J.Direct synthesis of timed asynchronous circuitsThis paper presents a new method to synthesize timed asynchronous circuits directly from the specification without generating a state graph. The synthesis procedure begins with a deterministic graph specification with timing constraints. A timing analysis extracts the timed concurrency and timed cau...1999
14 Myers, Chris J.Direct synthesis of timed asynchronous circuitsThis paper presents a new method to synthesize timed asynchronous circuits directly from the specification without generating a state graph. Our synthesis procedure begins with a deterministic signal transition graph specification to which timing constraints can be added. First, a timing analysis ex...1999
15 Mathews, V. JohnEfficient block-adaptive parallel-cascade quadratic filtersAbstract-This brief presents computationally efficient block-adaptive algorithms for quadratic filters employing parallel-cascade realizations of the system model. Parallel-cascade realizations implement higher order Volterra systems using a parallel connection of multiplicative combinations of lowe...1999
16 Mathews, V. JohnEqualization of recursive polynomial systemsAbstract-This letter presents some theorems for the exact and pth-order equalization of nonlinear systems described by recursive polynomial input-output relationships. It is shown that the nonlinear equalizers derived on the basis of this theory have simple and computationally efficient structures. ...1999
17 Kuramkote, Ravindra; Carter, JohnExploring the value of supporting multiple DSM protocols in Hardware DSM ControllersThe performance of a hardware distributed shared memory (DSM) system is largely dependent on its architect's ability to reduce the number of remote memory misses that occur. Previous attempts to solve this problem have included measures such as supporting both the CC-NUMA and S-COMA architectures is...DSM; Controllers1999

25 Johnson, Christopher R.; Parker, Steven G.; Hansen, Charles D.Interactive simulation and visualizationMost of us perform data analysis and visualization only after everything else is finished, which often means that we don't discover errors invalidating the results of our simulation until postprocessing.
