In this work we present an overview of the main advances in column sequence optimization in zeotropic systems, ranging from systems using only conventional columns, each with a condenser and a reboiler, to fully thermally coupled systems with a single reboiler and a single condenser in the entire sequence. We also review the rigorous design of distillation columns, or column sequences. In all t...

We investigate binary sequences which can be obtained by concatenating the columns of (0,1)-matrices derived from permutation sequences. We then prove that these binary sequences are subsets of a surprisingly diverse ensemble of codes, namely the Levenshtein codes, capable of correcting insertion/deletion errors; spectral null codes, with spectral nulls at certain frequencies; as well as being ...

Abstmct Sonar as well as other related sequences were introduced by Golomb and Taylor in [2 ] . Following a similar approachiwe introduce the concept of an extended sonar sequence. It is similar to that of a sonar sequence but blank columns are permitted. Several constructions of extended sonars are given. Our constructions are very close to ordinary sonar sequences. However they provide good i...

T he controllability properties of thermally coupled distillation sequences for the separation of ternary mixtures are compared with those of the conventional direct and indirect sequences. Closed loop responses to set point changes were performed, and controllers were tuned to minimize their ISE values. The results indicate that the integrated systems exhibit better control properties than seq...

Microarray contains a large matrix of information and has been widely used by biologists bio data scientist for monitoring combinations genes in different organisms. The coherent patterns all continuous columns are mined gene microarray matrices. It is investigated, this study, the developing time series similarity measure columns, as well evaluation function verifying proposed algorithm corres...

CHOI, KWANGBOM. P-Coffee: a new divide-and-conquer method for multiple sequence alignment (Under the direction of Dr. Dennis R. Bahler). We describe a new divide-and-conquer method, P-Coffee, for alignment of multiple sequences. P-Coffee first identifies candidate alignment columns using a position-specific substitution matrix (the T-Coffee extended library), tests those columns, and accepts on...

The Yale art historian George Hersey showed us the columns in Figure 1 and asked us whether the ideas of symmetry breaking could be used to help classify architectural columns. Provoked by this question and the intriguing columns in that figure, we attempted to answer Hersey in the following way. We view a column as a deformed cylinder and column symmetries as the subgroup of the symmetries of ...

The specialized regions of neocortex of mammals, called areas, have been divided into smaller functional units called minicolumns, columns, modules, and domains. Here we describe some of these functional subdivisions of areas in primates and suggest when they emerged in mammalian evolution. We distinguish several types of these smaller subdivisions. Minicolumns, vertical arrays of neurons that ...

This paper explores the basis on which reliable screening of distillation sequences for energy-efficient separation zeotropic multicomponent mixtures can be carried out. A case study natural gas liquids is used to demonstrate approach. To solve this generic problem, a algorithm has been developed using optimization superstructure sequence synthesis shortcut models, in conjunction with transport...
