Dynamic response

This paper introduces a practical and simple power control method for wind energy conversion systems based on a doubly-fed induction generator. Due to the limitations of traditional proportional-integral controllers when the parameters of the doubly-fed induction generator and wind speed vary, fuzzy control theory is applied to overcome these challenges.

The paper explores the application of the Modal Truncation algorithm in Model Order Reduction, focusing on its effectiveness in reducing high-dimensional mathematical model. The algorithm identifies dominant modes governing dynamic responses, discards the high-order model, and reconstructs a new model with reduced dimensions.

The dynamic response of a concrete pavement system with load transfer dowels under the effects of moving loads is a topic of interest to many scholars. However, to fully understand the nature of the stress-strain state of the concrete slab, load transfer dowels, and the subgrade in the pavement structure, further research is needed.

Health education for patients is one of the essential tasks of physicians in patient care and treatment. To improve the effectiveness of health care and treatment, physicians must spend more time with patients. The interaction of physicians in performing health education for patients must be really enthusiastic, dynamic and responsive to the needs of each patient.

The paper proposes an empirical VAR for the UK open economy in order to measure the effects of monetary policy shocks from 1981 to 2003. The identification of the VAR structure is based on short-run restrictions that are consistent with the general implications of a New Keynesian model. The identification scheme used in the paper is successful in identifying monetary policy shocks and solving the puzzles and anomalies regarding the effects of monetary policy shocks.

The aim of the research was the processing of the vibration signatures from healthy and damaged composite beams acquired with the help of a Scanning Laser Vibrometer (SLV) upon excitation and analysis of the mode shapes acquired for damage detection. The displacement mode shapes acquired were then converted into curvature mode shapes with the help of a Central Difference Approximation method (CDA).

This paper intends to present the System Dynamics (SD) as a novel method to simulate the thrust force developed during drilling of GFRP composites. Good quality holes are extremely fundamental so as to accomplish equally good joints amid creation of components prepared from composite for better execution.

This thesis aimed to apply the SEM for dynamic analysis of cracked beam subjected moving harmonic force in the frequency domain. Namely, the frequency response of a cracked beam subjected to moving harmonic force is obtained explicitly and examined in dependence upon the load and crack parameters. This task is acknowledged herein spectral analysis of cracked beam subjected to moving load.

DNA ligases are the enzymes responsible for the repair of single-strandedanddouble-strandednicks indsDNA.DNA ligases are structurally similar, possibly sharing a common molecular mechanism of nick recognition and ligation catalysis. This mechanism remains unclear, in part because the structure of ligase in complex with dsDNAhas yet to be solved.DNA ligases share common structural elementswith DNA polymerases, which have been cocrystallized with dsDNA. Based on the observed DNA polymerase–dsDNA interactions, we propose a mechanism for recognition of a single-stranded nick by DNA ligase....

Ca 2+ and cAMP are ubiquitous second messengers in euk-aryotes and control numerous physiological responses ran-ging fromfertilization to cell death induction 1 . Todistinguish between these different responses, their subtle regulation in time, space and amplitude is needed. Therefore, the char-acterization of the signalling process requires measurement of secondmessengers with tools of precise localization, high dynamic range and as little disturbance of cell physiology as possible.

Cells must be able to process multiple information in parallel and, more-over, they must also be able to combine this information in order to trigger the appropriate response. This is achieved by wiring signalling pathways such that they can interact with each other, a phenomenon often called crosstalk.
