High Multiplicity Strip Packing
An instance of the two-dimensional strip packing problem is specified by n rectangular items, each having a width, 0 < wn ≤ 1, and height, 0 < hn ≤ 1. The objective is to place these items into a strip of width 1, without rotations, such that they are nonoverlapping and the total height of the …

Packing and Counting Permutations
… aspects of permutation classes: enumeration and packing. <br></br><br></br> Our work on enumeration consists of two campaigns. First, we enumerate all juxtaposition classes of the form “Av(abc) next to Av(xy)”, where abc and xy are permutations of lengths three and two, respectively. We represent …

Topics in Packing and Scheduling
Packing and scheduling models include some of the most fundamental problems in operations research and computer science. These broad classes include a wide range of models with applications including logistics, production planning, wireless network design, circuit design, and cloud computing, to …

Packing materialities: marketising trans prosthetics
This thesis is concerned with the practice of packing undertaken by trans men and transmasculine people, and with the commercialisation of products designed for use in this practice. To pack is to wear an object in your underwear to emulate in some way or shape a penis, and to provide the feeling …

Structured packing in air distillation
… when it is advantageous to use structured packing in air separation plant. A model of a low pressure cycle was developed to calculate the power saved when packing is used, and cost models were developed for the columns and cold box. The rate of return was calculated on the extra investment …

Edge-packing by isomorphic subgraphs
Maximum G Edge-Packing (E Pack<sub>G</sub>) is the problem of finding the maximum number of edge-disjoint isomorphic copies of a fixed guest graph G in a host graph H. The problem is primarily considered for several guest graphs (stars, paths and cycles) and host graphs (arbitrary graphs, planar …

Exploring Zirconia as a Column Packing Material
Zirconia is one of the most promising column packing materials for High Performance Liquid Chromatography (HPLC). The perfect HPLC support material should be energetically homogenous, have a high surface area on which different chemical species can reversibly attach and be physically and chemically …

Random Sphere Packing Model of Heterogeneous Propellants
In addition, a method of analysis of the morphology of heterogeneous propellants is developed which uses the concept of multi-point correlation functions. A set of intrinsic length scales of local density fluctuations in random heterogeneous propellants is identified by performing a Monte-Carlo …

Approximation algorithms for packing and scheduling problems
… optimization problems. Specifically, we study packing and scheduling questions of relevance in several areas of operations research, including interconnection networks and switch scheduling, VLSI design, and processor scheduling. The first chapter studies a natural edge-coloring question …

Circle Packing in Euclidean and Hyperbolic Geometries
… a configuration of circles is called a circle packing. We shall give evidence for the existence and uniqueness of circle packings generated by such graphs, as well as an explanation of the algorithms used to find and output a circle packing on the complex plane and hyperbolic disc.

Packing of particles during softening and melting process.
Softening deformation of iron ore in the form of sinter, pellet, and lump ore in the cohesive zone of an ironmaking blast furnace is an important phenomenon that has a significant effect on gas permeability and consequently blast furnace production efficiency. The macroscopic softening deformation …

Mass transfer coefficients and effective area of packing
… (k [subscript G]) of eleven structured packings and three random packings were measured consistently in a 0.428 m packed column. Absorption of CO₂ with 0.1 gmol/L NaOH with 3.05 m packing was used to measure a [subscript e], while air stripping of toluene from water with 1.83 m packing …

The acetanilide crystal structures: packing and conformational similarities
… The assembly of these one-dimensional packing features governs in particular the crystal structures of the para substituted acetanilides. The amide-amide hydrogen bonded chains were very persistent in all the acylanilides. The amide substituent had a larger effect on the chain geometry …
