13 Stoller, Leigh B.Direct deposit: a basic user-level protocol for carpet clusters?This note describes the Direct Deposit Protocol (DDP), a simple protocol for multicomputing on a carpet cluster. This protocol is an example of a user-level protocol to be layered on top of the low-level, sender-based protocols for the Protocol Processing Engine. The protocol will be described in te...Direct Deposit Protocol; DDP; Carpet clusters; Multicomputing; User-level protocol1995
14 Henderson, Thomas C.Evolutionary teleomorphologyThe physical layout of organs and neural structures in biological systems is important to their functioning, and is the result of evolutionary selection forces. We believe this is true even at the individual neuron level, and should be accounted for in any bio-based approach. In particular, when tr...Evolutionary teleomorphology; Bio-based approach; Physical layout problem; PLP; Neurons; Nodes1995
15 Gopalakrishnan, GaneshExplicit-enumeration based verification made memory-efficientWe investigate techniques for reducing the memory requirements of a model checking tool employing explicit enumeration. Two techniques are studied in depth: (1) exploiting symmetries in the model, and (2) exploiting sequential regions in the model. The first technique resulted in a significant reduc...Verification; Model checking tool; Memory-efficient1995
16 Thompson, William B.Exploiting discontinuities in optical flowMost optical flow estimation techniques have substantial difficulties dealing with flow discontinuities. Methods which simultaneously detect flow boundaries and use the detected boundaries to aid in flow estimation can produce significantly improved results. Current approaches to implementing these ...Optical flow; Discontinuities1995
17 Thompson, William B.Feature-based reverse engineering of mechanical partsReverse engineering of mechanical parts requires extraction of information about an instance of a particular part sufficient to replicate the part using appropriate manufacturing techniques. This is important in a wide variety of situations, since functioning CAD models are often unavailable or unus...Mechanical parts1995
18 Richardson, William F.The Fred VHDL ModelThis is the companion document to my dissertation. It contains 47 pages of schematics, and 163 pages of VHDL code. It is pretty meaningless without the dissertation, and it only exists because I felt that I should archive this information somewhere.1995
19 Richardson, William F.Fred: an architecture for a self-timed decoupled computerDecoupled computer architectures provide an effective means of exploiting instruction level parallelism. Self-timed micropipeline systems are inherently decoupled due to the elastic nature of the basic FIFO structure, and may be ideally suited for constructing decoupled computer architectures.
