Utilities, such as steam or cooling water, have shown to play an important role within the process industry, since a malfunctioning utility is a plant-wide disturbance that can lead to large revenue losses due to reduced production quantities. This work focuses on identifying disturbances on utilities that give economical consequences. Measures of utility availability and area availability are int
This paper presents a systematic approach to robust preconditioning for gradient based non-linear inverse scattering algorithms. In particular, one- and two-dimensional inverse problems are considered where the permittivity and conductivity profiles are unknown and the input data consists of the scattered field over a certain bandwidth. A time-domain least-squares formulation is employed and the i
Abstract in UndeterminedExtreme down-scaling of nanoelectronic devices by top-down fabrication methods may be hindered by several obstacles, such as the cost for patterning and processing, or inferior device performance due to process-induced damage. In this presentation I will present a bottom-up approach for nanometer-scale device fabrication, based on seeded growth of semiconductor nanowires, u
In this paper 3D electromagnetic simulations of an antenna array have been performed. The array is intended for automotive radar applications at 24 GHz. It is constructed from dipole antenna element patches, which are fed in the center by a differential signal. The dipole antenna element patches are simulated assuming a standard off the shelf substrate. They have a standing wave ratio less than 3
From a universal design perspective, products should attract both people with disabilities and other persons. Design of chairs has decisive importance for activity and independence of users with physical disabilities. In an experimental study aiming at an easy chair with universal design qualities, six able-bodied young adults were asked to position a wide range of photo-represented chairs, includ
Wind turbines operating in wind farms are coupled by the wind flow. This coupling results in increased turbulence levels for downwind turbines, and consequently higher maintenance costs. In this paper, we consider a scenario where a wind farm is asked to produce less than maximum power. The objective is to minimize fatigue loads on the turbines, while maintaining the desired power production. We s
Continued CMOS scaling is expected to make future micro-processors susceptible to transient faults, hard faults, manufacturing defects and process variations causing fault tolerance to become important even for general purpose processors targeted at the commodity market. Tomitigate the effect of decreased reliability, a number of fault-tolerant architectures have been proposed that exploit the nat
Background: The wide range of antibody specificity and affinity results from the differing shapes and chemical compositions of their binding sites. These shapes range from discrete grooves in antibodies elicited by linear oligomers of nucleotides and carbohydrates to shallow depressions or flat surfaces for accommodation of proteins: peptides and large organic compounds. Objectives: To determine t
The complexity of modern interdisciplinary health care practices, where different specialties work together to solve complex problems, challenges traditional approaches to organizational development and quality improvement. An example of this is surgery. This article describes and evaluates an action-oriented method to facilitate organizational development and innovation at an operating unit, cent
