Fluidization of initially segregated binary mixtures has been investigated for particle systems of the same material. This paper reports experiments conducted in 0.055m diameter fluidizes bed for binary mixtures composed of sands whose sizes ranged from 450 to 1450mm. An empirical relationship, Utf = 0.95 UF (dR)0.87, was derived in terms of the minimum fluidization of the smaller particle, UF ...

A new analytical study performed to investigate the effect of the temperature difference between gas and particle in propagation of the spherical flames. The combustible system is containing uniformly distributed volatile fuel particles in an oxidizing gas (Air) mixture. The model includes evaporation of volatile matter of dust particles to known gaseous fuel (methane) and the single-stage reac...

There is a wide range of performance models being developed for the analysis of present and future generation systems. A major concern in using these models however, is the provision of realistic application workload information. There is a need for a common interface that couples generic workload information to the underlying hardware characteristics. In this work a three level framework is de...

Microprocessor design time and effort are getting impractical due to the huge number of simulations that need to be done to evaluate various processor configurations for various workloads. An early design stage methodology could be useful to efficiently cull huge design spaces to identify regions of interest to be further explored using more accurate simulations. In such an early design stage m...

The protein structure prediction (PSP) problem is considered an open problem as there is no recognized ”best” procedure to find solutions. Moreover, this problem presents a vast search space and the analysis of each protein conformation requires significant amount of computing time. We propose a reduction of the search space by using the dependent rotamer library. Also this work introduces new ...

In this study, different objective quality measures for the performance prediction of noise reduction schemes are compared to subjective data from psychoacoustic listening tests. It is shown that the considered perceptual measures are appropriate to define a quality test-bench which can be used for the development and optimization of noise reduction schemes.

As Cloud computing has gained much popularity recently, many organizations consider transmitting their large-scale computing-intensive programs to cloud. However, cloud service market is still in its infant stage. Many companies offer a variety of cloud computing services with different pricing schemes, while customers have the demand of "spending the least, gaining the most". It makes a challe...

The spectrum of approaches to performance prediction of parallel systems ranges from low-cost, lowprecision compile-time methods to high-cost, highprecision methods with an equal variety of underlying modeling formalisms (e.g., task graphs, queueing networks, simulation languages) which are mutually incompatible. A performance prediction technique is described which uni es a number of existing ...
