A Comparison of Model Reduction Techniques for Multi-Zone Building Thermal Models

In this thesis model order reduction techniques are applied to a set of systems representing the thermodynamics of a multi-zone building. The models are intended to be used in a model predictive control (MPC) application, with the individual zones defined using a simplified two temperature model. There has been an increased interest in model identification and reduction for MPC applications of building models that include multi-zone and non-linear models, but the most of this work has focused on models where individual zones are represented with a higher order model. Manual pole/zero removal, dominant eigenvalue, and balanced model reduction methods are presented, along with a proposed application specific method that takes advantage of the zone model’s simplified form. The proposed method treats a set of the zones as a common airspace with comparable control and reduces the underlying resistor/capacitor (RC) network. These methods are applied to a two zone and a six zone model with various coupling configuration tested. The general form of the multi-zone model proves difficult to reduce without making modification to the original form. The effects of reducing the inputs and outputs, through methods such as using a common temperature setpoint, are presented with significant improvements to reduction capabilities. Balanced model reduction the 18th order system down to 9th and 5th based on which inputs and outputs are reduced, and the application specific methods is able to reduce the same system down to a 3rd order model when the inputs and outputs are fully reduced

Letter from John Burroughs to John Muir, [1910] Mar 31.

West Park, N.Y.Mch.31,[1910?].Dear John Muir:I am sure you will be glad to know that I have changed the Yosemite paper--cut out much of the matter that displeased you. I had some correspondence with Willis of the U.S. Geological Survey and got his views and the views of others on the geological history of the great Valley, and changed my article accordingly. My paper on the Grand Canyon may appear in July Century. Johnson could not stand all the geology, so I cut much of it out. I am to have a paper in the May Atlantic called Through the Eyes of the Geologist . If you should chance to see it I should be glad of any criticism you might make. I will not squeal, sit down upon me never so hard.I am hoping you will come East this spring or summer and will stop a while with me at Slabsides. We will make excursions to the Catskills and to the Shawangunk and study the Silurian and Devonian rocks. Maybe the Browns will come. I have written him. If you come we will go and see the Harrimans at their new place. The Osborns, too, would be delighted to see you, as will hundreds of others. We will go and see Roosevelt, too, or get him up here.I had a glimpse of Dr. Barrus yesterday. She was looking fine. Did she write you that she is to have a paper on us two Johnnys in the Century? -more about you than about me., I hope you are well and that I shall see you this season.Affectionately,John Burroughs0474

Col. Francis Nash\u27s Revolutionary War Encampment on Little River Neck, Horry County, South Carolina

This article gives details about the encampment of Revolutionary War troops, commanded by Col. Francis Nash, on Little River Neck in December 1776. It contains excerpts from the account of Hugh McDonald. Little River Neck is private property located in the northeastern corner of Horry County, South Carolina.https://digitalcommons.coastal.edu/hcac-research/1003/thumbnail.jp

Annotations on - An Errand to the South in the Summer of 1862, By William Wyndham Malet

The Rev. William Wyndham Malet visited South Carolina in the summer of 1862. He left his vicarage at Ardeley, Hertfordshire, England, to come to South Carolina to tell his sister, Mrs. Plowden C. J. Weston (formerly Emily Frances Esdaile), of a death in their family. While in South Carolina he spent the summer in Conwayboro (Conway) at Snow Hill, the war time refuge of Plowden C. J. Weston (Lt. Gov. of S.C. 1862-1864). Weston had evacuated his home, Hagley Plantation, on the lower Waccamaw River and moved his wife and approximately forty of his slaves upriver to Snow Hill in order to avoid Union forces who were looting the homes along the lower Waccamaw River. In the following annotated extracted passages the Englishman describes his arrival at Conwayboro, South Carolina and gives some details about plantation life during the Confederate War period.https://digitalcommons.coastal.edu/hcac-research/1001/thumbnail.jp

Annotations on - Travels in the Confederation [1783-1784], Journal of Johann David Schoepf

Johann David Schoepf was born in 1752 in the German principality of Bayreuth. Educated as a physician and natural scientist, he arrived at New York in 1777 as chief surgeon of the Ansbach troops in the service of George III. Returning to Europe in 1784, Schoepf died in 1800 while serving as president of the United Medical Colleges of Ansbach and Bayreuth. In these selected passages, Schoepf describes his travel along the north-eastern coastline of South Carolina, through what is now Horry County, and along the beach of Long Bay, now known as Myrtle Beach. He gives a description of an indigo plantation located just above what is now called Singleton Swash and describes both the flora and fauna along his route. Annotations have been added to help clarify his entries.https://digitalcommons.coastal.edu/hcac-research/1005/thumbnail.jp

Annotations on Selected Entries – The Journal and Letters of Francis Asbury [1771-1816]

English-born Francis Asbury (1745-1816), famed bishop of the American Methodist movement, visited the area that is now known as Horry County, South Carolina several times during the period 1785 to 1815. Asbury spread Methodism in America as part of the Second Great Awakening. In his journal and letters he left us several interesting accounts of the area and its residents. Annotations have been added in order to clarify his remarks.https://digitalcommons.coastal.edu/hcac-research/1006/thumbnail.jp

Annotations on - A New Voyage to Georgia. By a Young Gentleman. (1734)

An account of a “young gentleman” from London, England describing his travels in the colonies of Georgia, South Carolina and North Carolina. These annotated excerpts focus on his time in South Carolina, particularly in the region of the Waccamaw River, and give us an early description of the area that is now Horry (oh-ree) County, South Carolina from the viewpoint of an Englishman in 1734.https://digitalcommons.coastal.edu/hcac-research/1002/thumbnail.jp
