The thermal inactivation characteristics of Bacillus subtilis A spores suspended in skim milk with the use of large-scale ultrahigh temperature (UHT) processing equipment were investigated in terms of survival as measured with two plating media. Data on survival immediately after UHT treatments were recorded in temperature-survivor curves, time-survivor curves, and decimal reduction time (DRT) ...
Low-frequency errors of thin-film multijunction thermal voltage converters are estimated using a simple model based on easily measured parameters. The model predictions are verified by measuring the converter’s frequency characteristic using a digitally synthesized source.
In this work, we characterize the power and thermal characteristics of a Pentium M system in response to a widely available power-management mechanism, DVFS (dynamic voltage and frequency scaling) and cooling capacity. We observe transient and steady-state responses to changing the DVFS state with custom microbenchmarks and develop a model that captures the power-thermal relationship for this s...
To estimate the time delay between the planetary temperature change and the change of the incoming solar radiation fraction absorbed by the ocean and the atmosphere, the analytical energy balance model is presented. The model generalization allows of using averaged data for model parameterization. Using the model, the time delay is investigated on four model cases of absorbed radiation change. ...
The thermal inactivation characteristics of Bacillus stearothermophilus (1518) spores and putrefactive anaerobe (PA) 3679 (NCA) spores suspended in skim milk were determined after treatment in pilot-plant ultrahigh-temperature (UHT) processing equipment. Temperature-survivor curves were constructed from survival data to emphasize the critical nature of temperature control in process evaluation....
We study the Hawking thermal spectrum in dragging coordinate system and the tunneling radiation characteristics of hot NUT-Kerr-Newman-Kasuya spacetime. The tunneling rates at the event and cosmological horizon are found to be related to the change of Bekenstein-Hawking entropy. The radiation spectrum is not pure thermal and thus there is a correction to the Hawking thermal spectrum. PACS: 04.7...
The present numerical attempt deals the sway to transfer of heat and mass characteristics on the time-dependent hydromagnetic boundary layer flow of a viscous fluid over an exponentially inclined preamble stretching. Furthermore, the role of viscous heating, thermal radiation, uneven energy gain or loss, velocity slip, thermal slip and solutal slips are depicted. The prevailing time-dependent P...
The microstructure and local mechanical characteristics of thermal spray ferrous coatings have been determined. The emphasis has been on coatings made by the high velocity oxyfuel (HVOF) process, especially the role of Al alloy additives. The oxide phase present in the material and preferred pathways for local cracking and separation have been determined. Thin intersplat oxide layers emerge as ...
This work encompasses the development of low-viscosity cyclic oligomer underfill formulations that cure without heat evolution. Boron nitride, silica-coated aluminum nitride, and alumina ceramic powders were used as fillers in cyclic butylene terephthalate oligomer melts. The melts were heated with a suitable catalyst to induce polymerization. The effects of the filler type and composition on t...
