Small and medium-sized companies increasingly turning their attention towards the fourth industrial revolution. In order to increase own long-term competitiveness, there is a growing desire make production smarter, more efficient, safer sustainable through new technologies. Often, however, existing plants cannot be easily replaced by modern equipment. The reasons for this can high investment co...

This study investigates a parameterization of all output-rectifying retrofit controllers for distributed design structured controller. It has been discovered that can be characterized as constrained Youla parameterization, which is difficult to solve analytically. For synthesis, tractable and insightful class controllers, referred introduced. An unconstrained derived under technical assumption ...

This article presents the results of a seismic risk assessment of the bridge network in Charleston, South Carolina and the surrounding counties to support emergency planning efforts, and for prioritization of bridge retrofit. This study includes an inventory analysis of the approximately 375 bridges in the Charleston area, and convolution of the seismic hazard with fragility curves analytically...

61] In addition to conventional measurement microphones, dummy heads are more and more used for physical as well as subjective noise evaluation. Within the DIN, a study group (A2 AK8) was formed, analyzing features of commercially available dummy heads. It was found that mainly because of geometrically different shells, different dummy heads produce different sound images. In practical applicat...

We examine the cost-effectiveness of improvements in woodframe buildings. These include retrofits, redesign measures, and improved quality in 19 hypothetical woodframe dwellings. We estimated cost-effectiveness for each improvement and each zip code in California. The dwellings were designed under the CUREE-Caltech Woodframe Project. Costs and seismic vulnerability were determined on a componen...
