Select Plants

Tough-but-beautiful plant picks There’s a growing demand for dependably hardy plants that require less maintenance and less water, but look no less beautiful in the garden. Plant Select—the leading purveyor of plants designed to thrive in difficult climates—meets this need by promoting plants that allow gardeners everywhere to have stunning, environmentally-friendly gardens that use fewer resources. Pretty Tough Plants highlights 135 of Plant Select’s top plant picks. Each profile features a color photograph and specific details about the plant’s size, best features, and bloom season, along with cultural needs, landscape features, and design ideas. The plant list includes perennials and annuals, groundcovers, grasses, shrubs, and trees. A chart at the end of the book makes it easy to choose the right plants for specific conditions and needs.

Highlighting more than 1,000 plants--from trees and shrubs to vines and grasses--this updated edition of Odenwald and Turners guide keeps with a traditional emphasis on the practical use of plants to solve and prevent landscape design problems.

"The first resource of its kind, featuring plants handpicked by experts for their ability to thrive in the challenging conditions of the High Plains and intermountain states and beyond"--Cover, p. 4.

Control of multivariable industrial plants and processes has been a challenging and fascinating task for researchers in this field. The analysis and design methodologies for multivariable plants can be categorized as centralized and decentralized design strategies. Despite the remarkable theoretical achievements in centralized multiva- able control, decentralized control is still widely used in many industrial plants. This trend in the beginning of the third millennium is still there and it will be with us for the foreseeable future. This is mainly because of the easy implementation, main- nance, tuning, and robust behavior in the face of fault and model uncertainties, which is reported with the vast number of running decentralized controllers in the industry. The main steps involved in employing decentralized controllers can be summarized as follows: • Control objectives formulation and plant modeling. • Control structure selection. • Controller design. • Simulation or pilot plant experiments and Implementation. Nearly all the textbooks on multivariable control theory deal only with the control system analysis and design. The important concept of control structure selection which is a key prerequisite for a successful industrial control strategy is almost unnoticed. Structure selection involves the following two main steps: • Inputs and outputs selection. • Control configuration selection or the input-output pairing problem. This book focuses on control configuration selection or the input-output pairing problem, which is defined as the procedure of selecting the appropriate input and output pair for the design of SISO (or block) controllers.
