Consider the situation where one is faced with a sequence of knapsack type problems which involves additional constraints on the permissible number of certain types of knapsack fillers to be used over the sequence. This research is concerned with determining good and perhaps optimal solutions which maximize the total value...
This is a fundamental study of the mechanism of protein particle
removal during flow through sandy soil. Mathematical models for
diffusion-adsorption and diffusion-convection-adsorption processes
were developed and compared with experimental data. An attempt was
made to calculate the distance over which the adsorption forces act.
The differential equation for the...
From a population of cells of Pseudomonas aeruginosa sensitive 33 parts per million (ppm) and 0.1 mg per ml of quaternary
ammonium (QAC) and chloramphenicol respectively, pure strains
resistant to 750 ppm and 50 mg per ml of these antibiotics were isolated.
Lipids from the sensitive and resistant cells grown...
The decay of Pd¹⁰⁹, Pd¹¹¹ [superscript g], and Pd¹¹¹ [superscript m] produced by thermal neutron irradiation of palladium targets has been investigated. Gamma ray energies and relative intensities have been measured with a high resolution Ge(Li) spectrometer. From energy sums and relative intensity considerations level schemes for Ag ¹⁰⁹ and...
In this dissertation, a two stage flexible flow shop scheduling problem is studied, where in stage 1, there are identical batch processors (burnout ovens) and in stage 2, there are identical discrete processors (furnaces). Batch processors perform a pre-heating process on a batch of jobs at a time and discrete...
