Fluctuations In Finite N Equilibrium Stellar Systems, Martin D. Weinberg Jul 1997

Fluctuations In Finite N Equilibrium Stellar Systems, Martin D. Weinberg

Astronomy Department Faculty Publication Series

Gravitational amplification of Poisson noise in stellar systems is important on large scales. For example, it increases the dipole noise power by roughly a factor of six and the quadrupole noise by 50% for a King model profile. The dipole noise is amplified by a factor of fifteen for the core-free Hernquist model. The predictions are computed using the dressed-particle formalism of Rostoker & Rosenbluth (1960) and are demonstrated by n-body simulation. This result implies that a collisionless n-body simulation is impossible; The fluctuation noise which causes relaxation is an intrinic part of self gravity. In other words, eliminating two-body …


Dynamics Of An Interacting Luminous Disk, Dark Halo, And Satellite Companion, Martin D. Weinberg Jul 1997

Dynamics Of An Interacting Luminous Disk, Dark Halo, And Satellite Companion, Martin D. Weinberg

Astronomy Department Faculty Publication Series

This paper describes a method for determining the dynamical interaction between extended halo and spheroid components and an environmental disturbance. One finds that resonant interaction between a galaxy and passing interlopers or satellite companions can carry the disturbance inward, deep inside the halo, where it can perturb the disk. Applied to the Milky Way for example, the LMC and SMC appear to be sufficient to cause the observed Galactic warp and possibly seed other asymmetries. This is a multi-scale interaction in which the halo wake has a feature at roughly half the satellite orbital radius due to a 2:1 orbital …

Efficient Striping Techniques For Variable Bit Rate Continuous Media File Servers, Prashant J. Shenoy May 1997

Efficient Striping Techniques For Variable Bit Rate Continuous Media File Servers, Prashant J. Shenoy

Computer Science Department Faculty Publication Series

The performance of striped disk arrays is governed by two parameters: the stripe unit size and the degree of striping. In this paper, we describe techniques for determining the stripe unit size and degree of striping for disk arrays storing variable bit rate continuous media data. We present an analytical model that uses the server configuration and the workload characteristics to predict the load on the most heavily loaded disk in redundant and non-redundant arrays. We then use the model to determine the optimal stripe unit size for different workloads. We also use the model to study the effect of …

Town Of Charlton, Massachusetts Rural Preservation Planning Study, Center For Economic Development Jan 1997

Town Of Charlton, Massachusetts Rural Preservation Planning Study, Center For Economic Development

Center for Economic Development Technical Reports

The town of Charlton, Massachusetts has experienced relatively high population growth over the past two and a half decades. From 1970 to 1990 the population more than doubled, and this growth is projected to continue into the next millennium. this boom in residential growth and development has placed financial pressures on the town, impacting the town's ability to provide services to its residents. For example, many of the new residents moving in to Charlton are families with children who increase the funding necessary for the town's school system budget. To offset these financial pressures, the town is actively engaging economic …


City Of Gardner, Massachusetts Inventory Of Existing And Removed Tanks, Center For Economic Development Jan 1997

City Of Gardner, Massachusetts Inventory Of Existing And Removed Tanks, Center For Economic Development

Center for Economic Development Technical Reports

The purpose of this project is to provide the City of Gardner with a list of contaminated sites in the Rear Main Street Area. During the past month, I have been researching potential brownfield locations within this corridor, and inputting them into a working database. Overall, the problem identified is that the city has little knowledge of how much land is contaminated within its city. Therefore, the goal of my project was to identify the parcels in the Rear Main Street Area that have been contaminated with hazardous materials.
