Incorporation Structural Health Monitoring In The Design Of Slip Formed Concrete Wind Turbine Towers – Progress Report

This report contains introduction to the subject as well as descriptions of the problems, a state-of-art overview, descriptions of the methods applied and of the results achieved so far. Furthermore, the report contains a plan for the remaining part of the project period. In the overall perspective, the project combines many different engineering disciplines and thus the report displays a variety of content. The reliability theory ties the different disciplines together, and the focus is chosen on the dominant uncertainties of the modal damage detection as a consequence barrier (risk reduction by decision rule), as the initial studies in the project indicated this as an interesting and innovative approac

Power Management for Energy Systems

The thesis deals with control methods for flexible and efficient power consumption in commercial refrigeration systems that possess thermal storage capabilities, and for facilitation of more environmental sustainable power production technologies such as wind power. We apply economic model predictive control as the overriding control strategy and present novel studies on suitable modeling and problem formulations for the industrial applications, means to handle uncertainty in the control problems, and dedicated optimization routines to solve the problems involved. Along the way, we present careful numerical simulations with simple case studies as well as validated models in realistic scenarios. The thesis consists of a summary report and a collection of 13 research papers written during the period Marts 2010 to February 2013. Four are published in international peer-reviewed scientific journals and 9 are published at international peer-reviewed scientific conferences

How Come We Can Say 'How Come'? Verb Second and V-to-I Movement in Present Day English and Early Modern English

In Present Day English (PDE), verb second (V2) occurs only in a few types of sentences, one of which is the interrogative main clause containing a wh-element that is not the subject of the sentence. Even then, it is never the main verb that travels to the second position. Instead, an auxiliary verb will move from the I° position to the C° position, while the main verb stays at its V° base position. For these reasons, the occurrences of the construction how come [emb] in PDE is surprising. Paying attention to the syntactic structures of PDE and Early Modern English (EModE), this paper investigates the ways in which the phrase how come [emb] is different from other PDE syntactic structures. It introduces and examines explanations for the syntax of the phrase, e.g., how come being a single constituent or come being a rare auxiliary verb.  However, these explanations are found to be unsatisfactory. This paper instead proposes that how come [emb] is an idiomatic expression with a V2 structure adhering to earlier syntactic conventions such as those found in EModE and earlier versions of English where main verbs were allowed to move out of their V° position.In Present Day English (PDE), verb second (V2) occurs only in a few types of sentences, one of which is the interrogative main clause containing a wh-element that is not the subject of the sentence.

ANALYSIS AND VISUALISATION OF SHOT PUT USING ROTATIONAL TECHNIQUE

The aim of the present project is to develop methods to analyse and visualise a shot put using a rotational technique. Trainers and athletes will benefit from this, by allowing them, in collaboration with the researcher, to obtain data that is pre-processed and easily understandable. In our opinion, one of the major problems in using biomechanical analyses in elite sports performance optimization is the translation of the recorded data to athlete-specific guidance. The solution in this study includes a full-scale animation of the athlete’s performance combined with quantification of selected parameters. Optimising performance in this type of movement is a combination of both physiological and technical factors. The physiological factors are related to muscle function and overall physique of the athlete and is mainly altered by strength training. The technical factors are more diffuse; overall, the athlete should use the optimal movement pattern given his or her mechanical capacity

Bioethanol from Germinated Grains.

The most well-known way to produce bioethanol is by the enzymatic hydrolysis and fermentation of starch. In a new project “BioConcens” (2007) sponsored by DARCOF (DAnish Research Center for Organic Food and farming) one aim is to develop a combined ethanol and biogas production for use in organic farming using starch containing biomass. Natural enzymes from cereals will be used for hydrolysis of starch to glucose in accordance with technology in brewing technology. Commercial enzymes are often produced from gene-modified organisms and will therefore not be used in the suggested organic context or process. A preliminary study was performed in which grains of wheat, rye, and barley were germinated using traditional methods applied in malting for beer production. During malting the amylase enzymes present in the grain are activated (autoamylolytic effect). Three steps were applied in the malting process; steeping, germination, and drying of the grains. After malting the grains were milled and mixed with water to 13% DM, cooked at 57.5C for 2 hours (to activate the enzymes), and cooled to 30C before adding Bakers Yeast. The results of this study indicate that efficient hydrolysis of starch can be achieved by activation of autoamylolytic enzymes in cereal grains after a malting process. The ethanol yields obtained in the autoamylolytic hydrolysis was comparable (or slightly higher) to that of reference experiments using commercial enzymes (amylases). The highest ethanol yield was obtained with wheat (0.34 g/g DM grain), followed by barley (0.31 g/g DM grain), and rye (0.29 g/g DM grain)

Danske Landbrugsorganisationer efter 1945 - hovedtræk og betragtninger

I denne artikel vil jeg give et overblik over udviklingen indenfor de danske landbrugsorganisationer efter Den 2. Verdenskrig. Det er en skildring, der ikke alene lægger vægt på sammenhængen mellem organisationerne, økonomien og de politiske forhold, men også indeholder personlige betragtninger fra 40 års virke i centrale dele af landbrugsorganisationerne
