چکیده

There have been many widely used genome rearrangement models, such as reversals, Hannenhalli-Pevzner (HP), and double-cut and join. Though each one can be precisely defined, the general notion of a model remains undefined. In this paper, we give a formal set-theoretic definition, which allows us to investigate and prove relationships between distances under various existing and new models. Among our results is that sorting in the HP model is equivalent to sorting in the reversal model when the initial and final genomes are linear uni-chromosomal. We also initiate the formal study of single-cut operations by giving a linear time algorithm for the distance problem under a new single-cut and join model.

Machine scheduling for multitask machining

Multitasking is an important part of today’s manufacturing plants. Multitask machine tools are capable of processing multiple operations at the same time by applying a different set of part and tool holding devices. Mill-turns are multitask machines with the ability to perform a variety of operations with considerable accuracy and agility. One critical factor in simultaneous machining is to cre...

The effect of price changes on optimum cut-off grade of different open-pit mines

Maximizing economic earnings is the most common goal in cut-off grade optimization of open-pit mining operations. When this is the case, the price of the product has a critical effect on optimum value of cut-off grade. This paper investigates the relationship between optimum cut-off grade and price to maximize total cash flow and net percent value (NPV) of operation. In order to visualize this ...

The Double Cut and Join Operation and its Applications to Genome Rearrangements

The aim of this thesis is to study mathematical models suitable for genome comparison in order to compute the evolutionary distance between two given genomes. We present a new model for genome comparison and apply the unifying double cut and join operation to this genome model. Different variants of the model are studied, yielding simpler formulations of earlier results. Unlike the traditional ...

DFT Study on the Possible Intramolecular Rearrangement of Four Monocyclic Monoterpenes

As the basis and preliminary work of future experimental study on PAHs formation under high temperature, theoretical computations on the intramolecular rearrangement reactions of sylvestrene (1-methyl-3-vinylcyclohexene) and 1,4-dimethyl-4-vinylcyclohexene are conducted and reveal that they may be transformed to themselves. The conversion between Dipentene and 2,4-dimethyl-4-vinylcyclohexen...

TIBA: a tool for phylogeny inference from rearrangement data with bootstrap analysis

TIBA is a tool to reconstruct phylogenetic trees from rearrangement data that consist of ordered lists of synteny blocks (or genes), where each synteny block is shared with all of its homologues in the input genomes. The evolution of these synteny blocks, through rearrangement operations, is modelled by the uniform Double-Cut-and-Join model. Using a true distance estimate under this model and s...
