Abstract:
Background: Claustrophobia associated with MRI scan is a well-recognized problem all over the world. The unpleasant psychological experience during MRI can lead to premature cancellation of the study resulting in non-interpretable data. In addition, performing future studies on the claustrophobic patient may not be possible leading to non-utilization of an important diagnostic modality. This study was conducted with the aim to determine a cheap and short intervention which can be applicable to small radiology set up as well.Methods: A prospective study was conducted at a tertiary care hospital from October 2016 to December 2016. Accompanying someone was the first strategy used to coped MR imaging claustrophobia followed by placebo (multivitamin), listening Quran and closed eye (blindfold). All those patients who failed to respond in these strategies were finally labeled as an unsuccessful candidate. Listening of Quran was selected as one of the tools as all the patients were Muslims in present study.Results: Among 84 claustrophobic patients, a closed eye was the most successful strategy found effective in (13) 81.2%, followed by placebo 66.7% patients, listening Quran (7) 30.4%, accompanying someone (15) 17.85% while 4% patients remained claustrophobic after application of all strategies. Significant association of accompanying someone and placebo was observed with education (p-value 0.037) and age of the patients (0.016) respectively.Conclusions: In general, placebo, being accompanied by someone and blindfold were found to be the most effective strategies to cope with MRI related claustrophobia. However, the success of these strategies is also dependent on certain factors like age, education status and socioeconomic status of the patients.

Abstract:
For entrepreneurial narratives to be effective, they need to be judged as plausible and have to resonate with an audience. Prior research has, however, not examined or explained how entrepreneurs try to meet these criteria. In this article, we addressed this question by analysing the micro-level arguments underpinning the pitch narratives of entrepreneurs who joined a business incubator. We discerned four previously unidentified rhetorical strategies that these entrepreneurs used to achieve narrative plausibility and resonance. Our findings further suggest that temporality and product development status may shape how entrepreneurs use these strategies. By outlining these aspects of entrepreneurial rhetoric, we contribute to opening up the black box of narrative resonance and plausibility and advance work on the role of rhetoric in entrepreneurship.

Abstract:
In magnetic resonance imaging (MRI), samples of the object's spectrum are measured in the spatial frequency domain (k-space). For a number of reasons there is a desire to reduce the time taken to gather measurements. The approach considered is to sample below the Nyquist density, using prior knowledge of the object's support in the spatial domain to enable full reconstruction. The two issues considered are where to position the samples (sampling strategies) and how to form an image (reconstruction techniques). Particular attention is given to a special case of irregular sampling, referred to as Cartesian sampling, in which the samples are located on a Cartesian grid but only constitute a subset of the full grid. A further special case is considered where the sampling scheme repeats periodically, referred to as periodic Cartesian sampling. These types of sampling schemes are applicable to 3-D Cartesian MRI, MRSI, and other modalities that measure a single point in 2-D k-space per echo. The case of general irregular sampling is also considered, which is applicable to spiral sampling, for example. A body of theory concerning Cartesian sampling is developed that has practical implications for how to approach the problem and provides intuition about its nature. It is demonstrated that periodic Cartesian sampling effectively decomposes the problem into a number of much smaller subproblems, which leads to the development of a reconstruction algorithm that exploits these computational advantages. An additional algorithm is developed to predict the regions that could be reconstructed from a particular sampling scheme and support; it can be used to evaluate candidate sampling schemes before measurements are obtained. A number of practical issues are also discussed using illustrative examples. Sample selection algorithms for both Cartesian and periodic Cartesian sampling are developed using heuristic metrics that are fast to compute. The result is a significant reduction in selection time at the expense of a slightly worse conditioned system. The reconstruction problem for a general irregular sampling scheme is also analysed and a reconstruction algorithm developed that trades off computation time for better image quality.

Full text
Abstract:
Fast field-cycling MRI (FFC-MRI) is a novel technique that promises to expand upon the diagnostic capabilities of conventional MRI by allowing the main magnetic field, B0, to be varied during the imaging pulse sequence. By doing this it is possible to gain access to information that is hidden to conventional scanners - namely the variation of the spin-lattice relaxation time, T1, with field strength, known as T1 dispersion. However, adding B0 as a new dimension to the imaging process necessitates a longer scan time which can limit the techniques application to clinical research. In this thesis, several methods are explored for reducing FFC-MRI scan times. A rapid imaging pulse sequence based on the well-known Fast Spin-Echo imaging sequence is presented, as well as an adaptation of the “keyhole” acquisition strategy. A method of determining T1 which requires significantly less data - and hence scan time - is also presented. When combined, these techniques are demonstrated to reduce total scan time from several hours to minutes without compromising access to T1 dispersion information. The techniques are demonstrated in phantom studies and in vivo results from volunteers are presented as proof of concept. The reduction in scan time demonstrated by these methods will significantly improve the applicability of FFC-MRI for clinical trials which are currently being worked towards.

Spinal cord injury (SCI) often results in irreversible paralysis of the limbs. Ongoing cellular recovery immediately after SCI is limited by the influx of inhibitory molecules that prevent neurons from infiltrating the lesion, resulting in a loss of axonal connections [57]. A range of studies have shown that a scaffold emiched in compounds that facilitate regeneration can lead to functional recovery. Therapeutic agents such as synthetic hydrogels have been shown to overcome the body's natural inhibitory response and promote permanent improvement in motor function. Hydrogel scaffolds with precise orientation have shown particular promise due to their proclivity for orienting lengthwise along the spinal cord, favoring axonal growth [7]. Standard magnetic resonance imaging (MRI) techniques optimized for visualizing the spinal cord can measure this degree of diffusion along white matter tracts. However, there are no published studies reporting the MRI parameters of the hydrogel substrates, and an understanding of how the material behaves in vitro may help guide the selection of an ideal compound by matching relaxation parameters and anisotropy measurements to those of spinal cord tissue. This study sought to characterize three hydrogel substrates of varying concentration using MRI to measure relaxation and diffusion properties. Relaxation times for agarose decreased as the concentration increased; whereas PuraMatrixTM relaxation times increased with increasing concentration. The addition offibronectin (an extracellular matrix support protein) significantly prolonged the relaxation times for the PuraMatrixTM solutions. No differences in proton density or restricted diffusion were observed. The results were compared to known relaxation and diffusion values for the spinal cord at 3T, highlighting certain concentrations that may be a best fit for use in the spinal cord. MRI is capable of quantifying substrate properties in vitro and then assessing their integration into tissue in vivo.

Abstract:
Coincidence of structural resonances with wind turbine dynamic forces can lead to large amplitude stresses and subsequent accelerated fatigue. For this reason, the wind turbine system is designed to avoid resonance coincidence. In particular, the current practice is to design the wind turbine support structure such that its fundamental resonance does not coincide with the fundamental rotational and blade passing frequencies of the rotor. For offshore wind turbines, resonance avoidance is achieved by ensuring that the support structure fundamental resonant frequency lies in the frequency band between the rotor and blade passing frequencies over the operating range of the turbine. This strategy is referred to as “soft-stiff” and has major implications for the structural design of the wind turbine. This paper details the technical basis for the “soft-stiff” resonance avoidance design methodology, investigates potential vulnerabilities in this approach, and explores the sensitivity of the wind turbine structural response to different aspects of the system’s design. The assessment addresses the wind turbine forcing functions, the coupled dynamic responses and resonance characteristics of the wind turbine’s structural components, and the system’s susceptibility to fatigue failure. It is demonstrated that the design practices for offshore wind turbines should reflect the importance of aerodynamic damping for the suppression of deleterious vibrations, consider the possibility of foundation degradation and its influence on the support structure’s fatigue life, and include proper treatment of important ambient sources such as wave and gust loading. These insights inform potential vibration mitigation and resonance avoidance strategies, which are briefly discussed.

Abstract:
Vibration-based energy harvesting has been widely investigated to as a means to generate low levels of electrical energy for applications such as wireless sensor networks. However, due to the fact that vibration from the environment is typically random and varies with different magnitudes and frequencies, it is a challenge to implement frequency matching in order to maximize the power output of the energy harvester with a wider frequency bandwidth for applications where there is a time-dependent, varying source frequency. Possible solutions of frequency matching include widening the bandwidth of the energy harvesters themselves in order to implement frequency matching and to perform resonance-based tuning approach, the latter of which shows the most promise to implement a frequency matching design. Here three tuning strategies are discussed. First a two-dimensional resonant frequency tuning technique for the cantilever-geometry energy harvesting device which extended previous 1D tuning approaches was developed. This 2D approach could be used in applications where space constraints impact the available design space of the energy harvester. In addition, two novel resonant frequency tuning approaches (tuning via mechanical stretch and tuning via applied bias voltage, respectively) for electroactive polymer (EAP) membrane-based geometry energy harvesters was proposed, such that the resulting changes in membrane tension were used to tune the device for applications targeting variable ambient frequency environments.

Abstract:
This paper discusses the semi-active control of helicopter ground resonance using magnetorheological (MR) damper. A dynamic model of a MR damper with bi-fold flow mode is built based on the hyperbolic tangent model and experimental data on mechanical properties; and its inverse model is derived for the control. An approximate analytical solution of a linear system is provided and a critical stability area is calculated according to the classical model of ground resonance and the method of determining the linear system stability. Then, Simulations are performed on the helicopter ground resonance model with three semi-active control strategies and the control performance is compared. Simulation results show that the comprehensive performance of the fuzzy skyhook control algorithm is superior to the on-off skyhook and continuous skyhook control algorithms.
