Sharp growth estimates for dyadic b-input T(b) theorems
No full textThe following deals with the T(b) theorems of David, Journé, and Semmes [7] considered in a dyadic setting. We find sharp growth estimates for a global and a local dyadic T(b) Theorem. We use multiscale analysis and Haar wavelets in the local case
Wave turbulence of a rotating array of quantized vortices in the T → 0 temperature limit
No full textThe dynamics of quantized vortices in the zero temperature limit is currently of great interest, particularly in the case of the Fermi superfluid He-B. Here we study wave turbulence, generated by the librating motion of a rotating cylindrical container filled with He-B, in the limit of vanishing viscous forces at temperatures . The polarization of the quantized vortices with respect to the axis of rotation is measured using non-invasive NMR techniques. We observe a decrease of the polarization when the librating motion is started, and a two-stage relaxation process when the modulation of the rotation velocity is stopped. The first relaxation process is associated with the dissipation of large-scale flow stored in inertial waves and the solid body rotation of the vortex array. From the decay of these energy reservoirs we determine the rate of energy dissipation of large-scale flow. The later second process is related to the relaxation of Kelvin waves on individual vortices. This process is monitored by the recovery of the polarization. The existence of a Kelvin wave cascade at the lowest temperatures is currently a central open question. We supply some evidence for the cascade
Design and Analysis of a Distributed TRIC concept Seamless Smart Morphing Wing
No full textThis thesis embarked upon establishing and validating a design process to build and control a distributed TRIC concept seamless smart morphing wing to achieve simultaneous load alleviation, flutter suppression and drag minimization capabilities. A novel aeroelastic simulation tool was built to carry out composite wing skin optimization, with prototype testing carried out to design a flexible connection between modules. The work output was a fully built morphing wing which was successfully tested in the TU Delft Open Jet Facility. Control of the wing was partially made feasible through the development of a surrogate model of the system which was also validated with DIC testing.https://www.youtube.com/watch?v=SdagIiYRWyA&t=1s Smart-X Alpha DemonstratorAerospace Engineerin
SHARP VERSUS BLUNT DIALYSIS NEEDLE USE WITH BUTTONHOLE METHOD: OPEN RANDOMISED TRIAL
No full textBACKGROUND: Current protocols recommend the use of a blunt needle to access the arteriovenous fistula via a buttonhole. This study aims to demonstrate whether a sharp needle can be used at the same buttonhole site without causing complications.
GOAL: To measure and compare fistula cannulation failures between the use of blunt and sharp needles. PLAN: Open-crossover randomised controlled trial.
PARTICIPANTS: Adult out-patients who had provided consent and were on dialysis with a mature arteriovenous fistula and buttonhole cannulation.
OUTCOME MEASURES: Failed cannulation-difficulty in inserting the needle and the trampoline effect; incidence of complications, such as infection and haematomas; times to haemostasis; patients' pain; and patients' preferences.
RESULTS: Based on analysis of the data from the 35 patients enrolled, no significant differences were detected in failed cannulation of the fistulae between the use of a blunt needle and a sharp needle for the 335 venous accesses (p = 0.071). However, a significant difference was detected for the 335 arterial accesses (p = 0.001), in which the sharp needle was more effective. Significant differences were also detected in the difficulty of insertion and in the trampoline effect for both venous and arterial access (p < 0.05); the use of a sharp needle was more favourable.
CONCLUSION: This study demonstrates an increased incidence of failed cannulation using a blunt needle compared with using a sharp needle, although this was not significant. In addition, the use of a sharp needle did not result in any increase in complications

Pelevin’s Trinity in the novel “t”: author – protagonist – reader
No full textThe article attempts to interpret Pelevin's artistic strategy in the novel "T" by exploring its subject organization and addressing the key problems of the author, the protagonist, and the reader as they are seen by the researcher. The article analyzes the peculiarities of constructing the narrative reality in the novel "T", and goes on to discuss Pelevin's philosophic models of the development of the humankind, and the emergence of his new anthropology

On sharp characters of type
No full textsummary:For a complex character of a finite group , it is known that the product is a multiple of , where is the image of on . The character is said to be a sharp character of type if and . If the principal character of is not an irreducible constituent of , then the character is called normalized. It is proposed as a problem by P. J. Cameron and M. Kiyota, to find finite groups with normalized sharp characters of type . Here we prove that such a group with nontrivial center is isomorphic to the dihedral group of order 12
