A vibratory filtration model for candle-type filters

A candle filter was used to determine flow rate characteristics of filtering suspensions under axial vibrations. In this work, a generalised analysis of filtration under vibrating conditions was developed. The model required the use of experimental data interpretation. The analysis gives in a simplified form the complicated functional relationship between time, cumulative flow, vibration parameters and other process variables.Such a relationship can be used in the design of vibratory filters for predicting flow rate with time. These filters are useful in particle separation processes.

A new technique for on-line and off-line high speed computation

A novel technique for both online and offline computation is presented. With this technique, a reconstruction analysis in elementary particle physics, otherwise prohibitively long, has been accomplished. It will be used online in an upcoming Fermilab experiment to reconstruct more than 100000 events per second and to trigger on the basis of that information. The technique delivers 40 gigaoperations per second, has a bandwidth on the order of gigabytes per second, and has a modest cost. An overview of the program, details of the system, and performance measurements are presented     

Augmented rectangular load flow model

This paper presents some improvements to the load flow solution in rectangular coordinates. First, in an attempt to use as linear a model as possible, both the nodal equations and the bus constraints are retained. The Newton-Raphson (NR) method is then applied to the enlarged set of equations, and written in terms of bus voltages and currents. This scheme, combined with a simple procedure to handle PV buses, leads to a computationally efficient algorithm, particularly advantageous in the presence of zero-injection buses. Experimental results are provided comparing the performance of the proposed approach with that of the conventional formulation     

Dispersion Signatures, a Statistically Based, Dynamic, Digital Microwave Radio System Measurement Technique

Outage in digital microwave radio systems during multipath fading is highly correlated with the channel amplitude dispersion. This characteristic is exploited in a new digital microwave radio system measurement technique which yields dispersion signatures. These dispersion signatures can be readily applied to assess the effects of time varying channels on digital radio equipment. Thus, dispersion signatures can be used for in-service monitoring of equipment operation during actual fading. Routine maintenance assessment and laboratory evaluation of digital microwave radio equipment can also be readily carried out. The laboratory evaluation results can be used for system design both with and without diversity.
