In this paper, we present a finite-granularity, loading algorithm for a Discrete Multitone (DMT) modulation system. The proposed algorithm offers significant implementational advantages over the well-known water-pouring method and the earlier Hughes-Hartogs algorithm, while typically suffering only negligible performance degradation relative to the optimal solution. We also present simulation r...

In a recent paper [Zuriguel et al., Phys. Rev. Lett. 107, 278001 (2011)] it has been shown that the presence of an obstacle above the outlet can significatively reduce the clogging probability of granular matter pouring from a silo. The amount of this reduction strongly depends on the obstacle position. In this work, we present new measurements to analyze different outlet sizes, extending foreg...

With the rapid development of economic, gypsum is widely used in casting and other industry areas. In this paper, the result is obtained that the performance of plaster mold is better when gypsum-water ratio is 0.5. If the composition of gypsum slurry mixture ( -hemihydrate, mullite powder, zirconium powder, reinforcing fibers) is mullite powder: zircon flour: enhancing fiber = 1:0.25:0.2:0.02-...

Humans manipulate fluids intuitively using approximations of the underlying physical laws. In this paper, we explore a general methodology that robots may use to develop and improve strategies for overcoming manipulation tasks associated with appropriately defined loss functions. We focus on the specific task of pouring a liquid from a container (pourer) to another container (receiver) while mi...

AIM The aim of this study was to investigate the utility of a short, practical pouring exercise as a means of illustrating the details of the UK 'Sensible Drinking' guidelines. METHODS Participants (N = 297, 53% male) recruited at four Edinburgh employment sites, each completed a short non-standardized questionnaire and poured their 'usual measure of wine or spirit' into a glass (purchased fr...

Title of thesis : Simulation of random packing of hard spheres using Monte Carlo method Sung-Ho Park, Master of Science in Mechanical Engineering, 1990 Thesis directed by : Dr.Anthony D. Rosato, Assistant Professor Mechanical Engineering Department. A computer based method of generating a random packing of hard spheres is described. Using a Monte Carlo method as employed in the field of Computa...

The bone drilling temperature fields under different cutting parameters and cooling modes were experimental researched by using common twist drill, diamond punching pin, diamond bullet-like grinding head and diamond spherical grinding head. Three cooling modes were applied, namely, natural air cooling, normal saline pouring cooling and normal saline spray cooling. K-thermocouple was used to mea...

OBJECTIVE Occupational therapists are interested in quality of movement under different environmental conditions. It has been shown that during reaching tasks, the physical aspects of the objects to be grasped can influence the quality of movement. This study investigated whether perceived risk (water temperature) affected the quality of movement during a pouring task. METHOD In a counterbala...

The evaluation of proteins using sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) analysis is a common technique used by biochemistry and molecular biology researchers. For laboratories that perform daily analyses of proteins, the cost of commercially available polyacrylamide gels (~$10/gel) can be considerable over time. To mitigate this cost, some researchers prepare their...
