We report that star-shaped molecules with cholic acid cores asymmetrically grafted by low molecular weight polymers with hydrogen bonding end-groups undergo aggregation to nanofibers, which subsequently wrap into micrometer spherical aggregates with low density cores. Therein the facially amphiphilic cholic acid (CA) is functionalized by four flexible allyl glycidyl ether (AGE) side chains, whi...

SULE, AMBARISH MUKUND Hardware-Software Codesign of a Programmable Wireless Receiver System-on-a-chip. (Under the direction of Prof. William Rhett Davis). With gate counts and system complexity growing rapidly, engineers have to find efficient ways of designing hardware circuits. The advent of Hardware Description Languages and synthesis methodologies improved designer productivity by raising t...

The research leading to this paper was prompted by the need to estimate strength and stiffness of Rigid Rocking Cores (RRCs) as essential elements of resilient earthquake resisting structures. While a limited number of such studies have been reported, no general study in terms of physical properties of RRCs, their appendages and adjoining structures have been published. Despite the growing know...

Automobile light weight structural composites are subjected to the various loadings in their service lives. Honeycombs are increasingly used as core structures in automobile light weight structures as energy absorbers. In this paper the energy absorption of honeycomb panels under impact of cylindrical projectile is numerically and experimentally studied. The effect of the core materials and cro...

Classification problems have been introduced by M. Ziegler as a generalization of promise problems. In this paper we are concerned with solvability and unsolvability questions with respect to a given set or language family, especially with cores of unsolvability. We generalize the results about unsolvability cores in promise problems to classification problems. Our main results are a characteri...

The potential for higher performance from increasing on-chip transistor densities, on the one hand, and the limitations in instruction-level parallelism of sequential applications and in the scalability of increasingly complicated superscalar and multithreaded architectures, on the other, are leading the microprocessor industry to embrace chip multi-processors as a cost-effective solution for t...

We propose that a new type of drill, alternately known as a Fast Mechanical-Access Drill, or Coiled Tubing Drill for Ice (CTDI), be developed for polar research. The proposed drill is similar in concept to the latest coiled tubing (CT) drills used for commercial oil and gas development. CT drills use a metal or advanced-composite tube to deliver fluid downhole to a hydraulic motor that drives a...

As diminishing feature sizes drive down the energy for computations, the power budget for on-chip communication is steadily rising. Furthermore, the increasing number of cores is placing a huge performance burden on the network-onchip (NoC) infrastructure. While NoCs are designed as regular architectures that allow scaling to hundreds of cores, the lack of a flexible topology gives rise to high...

Multicore systems are of growing importance and 64128 cores can be expected in a few years. We expect datamining to be an important application class of general importance and are developing such scalable parallel algorithms for managed code (C#) on Windows. We present a performance analysis that compares MPI and a new messaging runtime library CCR (Concurrency and Coordination Runtime) with Wi...

this article addresses a multi-stage flowshop scheduling problem with equal number of unrelated parallel machines. the objective is to minimize the makespan for a given set of jobs in the system. this problem class is np-hard in the strong sense, so a hybrid heuristic method for sequencing and then allocating operations of jobs to machines is developed. a number of test problems are randomly ge...
