Prediction of Propulsor-Induced Maneuvering Forces Using a Coupled Viscous/Potential-Flow Method for Integrated Propulsors

Abstract : This thesis develops a method to analyze the maneuvering forces on surfaced and underwater vehicles with complex propulsors. The analysis method is developed for general propellers yet has unique applicability to model highly contracting stern flows associated with integrated propulsors. Integrated propulsors exhibit strong coupling of the various blade rows and duct, if present, to the vehicle stern. The method developed herein provides a robust means to analyze propulsor induced maneuvering forces including those arising from wake adapted, multi-stage, ducted propulsors. The heart of the maneuvering force prediction is a three-dimensional, unsteady lifting surface method developed as the first part of this thesis. The new method is designated PUF-14 for Propeller Unsteady Forces. The lifting surface method uses many advanced techniques. One significant advance is the use of a wake adapted lattice to model the flow through the propulsor. In related research, a 2-D Kutta condition has been augmented using Lagrangian interpolation to dramatically reduce the required computational time to model a 2-D gust. The second thrust of this thesis couples the unsteady lifting surface method with a three-dimensional, time-average Reynolds Averaged Navier Stokes flow solver. Rotating a propeller through a spatially varying flow field causes temporally varying forces on the propeller. From the converged coupled solution, the maneuvering and blade rate forces can be estimated. This thesis explores the relationship of time varying and time average forces in the flow solver and potential flow domains. Similarly, it explores the relationship of the effective inflow in the two domains. Finally, this thesis details the synergistic means to correctly couple the potential flow method to a viscous solver. Verification and validation of the method have been done on a variety of geometries and vehicles. Preliminary results show good correlation with experiment.
Performance evaluation of adaptive quantizers for a 16-kbits/s sub-band coder

Objective and subjective measures were obtained for a 4-band, 16-kbit/s sub-band coder utilizing adaptive quantizers with fixed and dynamic bit allocations. Objective measures indicated that block quantization (block companded PCM with a Gaussian probability density function, BCPCM-G) with dynamic bit allocation is slightly better than an adaptive differential PCM with a variable predictor (ADPCM-V) and fixed bit allocation, but outperforms ADPCM with a fixed predictor and fixed bit allocation (ADPCM-F) by 4-5 dB. Subjective measures, however, indicated that ADPCM-V has about 6-dB advantage over BCPCM-G. A comparison between ADPCM-V and ADPCM-F indicated that adaptive prediction provides a 4-5 dB objective gain and 16-dB subjective gain over fixed prediction. Further, all listeners preferred ADPCM-V over BCPCM-G and ADPCM-F, and 85% preferred BCPCM-G over ADPCM-F.
FROM MICRO TO NANORHEOLOGY : BASIC PRINCIPLES OF MICRORHEOLOGY MEASUREMENTS WITH FLUORESCENCE CORRELATION SPECTROSCOPY

Fluorescence correlation spectroscopy (FCS) represents one of the most sensitive fluorescence techniques due to single molecule detection. Microrheology serves as a tool to study viscoelastic properties of microenvironment of observed particles. We used 100 nm latex particles to study mean square displacement (MSD) of these particles in Newtonian fluids. The comparison of MSD determined by FCS compares well with those determined by dynamic light scattering method (DLS), classical microrheology (MR) or calculated theoretical MSD. FCS can be used to determine MSD in greater extent of time than both techniques and we can determine MSD in time range where MSD cannot be determined by MR or DLS. When pure diffusion model was used, MSD as a function of time exhibited curvature from theoretical curves. The fitting procedure of FCS autocorrelation function required triplet state model.
Perception of Grade Intervals

Stone and Sinnett (1968) presented pairs of grade intervals to college professors to be judged using a paired-comparison technique. The question asked of them was which member of each pair was phenomenally larger. Twelve intervals between A and F were judged, including intervals such as C+ to B-. They found the log of the phenomenal scale values best fit the physical A, B, C, D, F scale. These scale values fitted Thurstone's Case 111 rather rhan his Case V. Since pluses and minuses are not given in many colleges, would the same results be obtained using the conventional four-interval scale: AB, BC, CD, DF? The intent of this study was to investigate the relationship of the phenomenal to the physical grade scale in graduate students of educational psychology. Thirty-five graduate students in educational psychology were asked to judge which of each pair of grade intervals appeared larger. A = 4; B = 3; C = 2; D = 1; F = 0 anchors were given. All possible pairs were presented in such a manner as to minimize position effects. An alternate form of the task was presented 1 wk. later. Coefficients of consistence were computed for each S? The median coefficient was 1.00. Circular triads were infrequently noted. Analyses of variance of the frequencies of selecting each interval revealed an effect beyond the 5 per cent level (F = 19.21) of the physical grade (X) on the phenomenal ( Y ) . The trend was s~gniflcantly linear (F = 68.62). Tests for quadratic and cubic trends were also made. I: ratios were nonsignificant, 0.19 and 1.11, respectively. Adjusted z scale values were found to be AB = . 000; BC = ,018; CD = . 186; DF = . 665. The Mosteller test was made to determine goodness of fit to Thurstone Case V. The nonsignificant x 2 was 0.02. The hypothesis of fit to Case V was accepted, there being equal discriminal dispersions for each interval. The absolute average discrepancy among the judges was . 004, satisfactory for paired-comparison data. After 1 wk. Ss received an alternate form of the rask. The stability coefficient was 34 . Since both Ss and grade intervals differed from those in Stone and Sinnea's study, the data are not comparable. The present study indicates that higher marks have smaller phenomenal distances between them. As the intervals increase from high ro low grades the phenomenal distances increase. The most frequently occurring pattern of choices was: ALSmal l e s t , BC-Larger, CD-Larger rhan BC, DF-Largest. Perhaps to graduate students failure marks are the apogee of the academic universe but the orbits associated with A, B, C are less distinguishable and close to the perigee. On the other hand, the size of DF may be artifactual. It is the only interval in which a letter (E) next in alphabetical position is missing.
The induction of species-specific immunity against Schistosoma japonicum by exposure of rats to ultra-violet attenuated cercariae

SUMMARY Single percutaneous immunizations of Fischer rats with 1000 ultra-violet attenuated Schistosoma japonicum cercariae induced 52–88% resistance to challenge 4 weeks later. Increasing this to 3 immunizations induced 90% resistance to challenge, and this level of protection remained undiminished for up to 40 weeks after vaccination. Rats vaccinated with gamma-irradiated S. mansoni cercariae were resistant to challenge with S. mansoni but not S. japonicum. Similarly rats vaccinated with u.v. -attenuated S. japonicum cercariae were not resistant to heterologous challenge. Thus irradiated vaccines are species-specific in both permissive and non-permissive hosts.
Inactivation of the rhlA gene in Pseudomonas aeruginosa prevents rhamnolipid production, disabling the protection against polymorphonuclear leukocytes

Many of the virulence factors produced by the opportunistic human pathogen Pseudomonas aeruginosa are quorum‐sensing (QS) regulated. Among these are rhamnolipids, which have been shown to cause lysis of several cellular components of the human immune system, e.g. monocyte‐derived macrophages and polymorphonuclear leukocytes (PMNs). We have previously shown that rhamnolipids produced by P. aeruginosa cause necrotic death of PMNs in vitro. This raises the possibility that rhamnolipids may function as a ‘biofilm shield’in vivo, which contributes significantly to the increased tolerance of P. aeruginosa biofilms to PMNs. In the present study, we demonstrate the importance of the production of rhamnolipids in the establishment and persistence of P. aeruginosa infections, using an in vitro biofilm system, an intraperitoneal foreign‐body model and a pulmonary model of P. aeruginosa infections in mice. Our experimental data showed that a P. aeruginosa strain, unable to produce any detectable rhamnolipids due to an inactivating mutation in the single QS‐controlled rhlA gene, did not induce necrosis of PMNs in vitro and exhibited increased clearance compared with its wild‐type counterpart in vivo. Conclusively, the results support our model that rhamnolipids are key protective agents of P. aeruginosa against PMNs.
Microextraction techniques in breath biomarker analysis.

Breath volatile organic compound analysis may open a non-invasive window onto (patho)physiological and metabolic processes in the body. Breath tests require controlled sampling with respect to different breath phases and on-site and point-of-care applicability. Microextraction techniques such as solid phase microextraction (SPME) or needle-trap microextraction (NTME) meet these requirements. Small sample volumes and fast and controlled sample preparation combine on-site sampling and pre-concentration in one step. Detection limits in the low ppbV range and fast and simple processing facilitate the application of distribution-based SPME for screening and targeted analysis. Exhaustive NTME has shown further advantages such as fast and automated sampling, improved stability and reproducibility with improved detection limits. Combinations of different sorbents and thermal expansion desorption have shown most promising properties when applied to water saturated breath samples. This article addresses major chall.
Developing a new line of patter: can doctors change their consultations for sore throat?

Background and Objectives Doctors report pressure from peers to reduce prescribing of antibiotics for minor respiratory illnesses, and from patients to do the opposite. It has been suggested that doctors adopt a more patient‐centred consulting style in order to encourage patient satisfaction and shared decision‐making. No evidence exists that such changes are achievable. We developed a new, on‐site method for training postgraduates and used this for teaching patient‐centred intervention. Here, we examine whether this training method is associated with changes in consulting patterns in consultations for sore throat with children, among doctors from a single group practice.
Adaptation of acoustic model for Indonesian using varying ratios of spontaneous speech data

This paper presents our work in determining the ratio/amount of speech adaptation data that gives the optimum recognition error rate. Ten triphone acoustic models are first built in a similar-to-10-fold cross-validation manner using the dictated speech corpus. The whole dictated speech is read from 10 prepared transcripts by a diverse group of 301 Indonesian speakers. Each round of training uses utterances from one of the prepared transcripts. The resulting triphone models are also evaluated against its corresponding spontaneous speech evaluation set. The models that yield the lowest, the highest, and the closest-to-mean recognition error are then adapted to its corresponding spontaneous speech adaptation data using the Maximum A-posteriori Probability (MAP) method. The amount of the corresponding spontaneous speech adaptation data for each model is varied from 10% to 100% with a 10% increment. Thus for each of the 3 triphone models, there will be 10 resulting adapted models. The resulting adapted models are evaluated against their corresponding spontaneous and dictated speech evaluation set. The trend in the results shows that around 30–60% spontaneous speech adaptation data (roughly translates to 11.5 to 24 hours of speech) gives the most optimum (low) recognition error rate.
Hot-Electron-Induced MOSFET Degradation - Model, Monitor, and Improvement

Evidence suggests that MOSFET degradation is due to interface-states generation by electrons having 3.7 eV and higher energies. This critical energy and the observed time dependence is explained with a physical model involving the breaking of the = Si/sub s/H bonds. The device lifetime /spl tau/ is proportional to.
gp120 HIV envelope glycoprotein increases the production of nitric oxide in human monocyte‐derived macrophages

The effect of recombinant gp120 HIV envelope glycoprotein on the generation of free radicals by monocyte‐derived macrophages (MDM) was measured by EPR spin trapping with 5,5 ‐dimethyl‐1‐pyrroline‐N‐oxide (DMPO). After 1 day in culture, MDM produced a spin trap adduct of DMPO with hyperfine splitting constants superimposable on those of DMPO‐OH. The addition of gp120 to MDM increased the production of DMPO‐OH and after 1 h, the amount of DMPO‐OH produced by 40 μg/ml gp120 was about 300% that of untreated MDM. The use of selective inhibitors suggested the participation of the nitric oxide/l‐arginine oxidative pathway, but did not provide evidence for trapping of hydroxyl radical or other oxygen free radicals. The specificity of gp120 was proven by two different anti‐gp120 antibodies that either in‐hibited (polyclonal) or increased (monoclonal) the production of free radicals. Dexamethasone inhibited the effect of gp120, suggesting the possible involvement of an inducible nitric oxide (NO·) synthase. Moreover, treatment of MDM with gp120 for 15 h increased in a dose‐dependent manner the production of NO2 ‐, a stable end product of NO·. Soluble CD4 did not modify the intensity of the DMPO‐OH adduct, whereas yeast mannan and Ca2+‐chelators abolished the increase in the DMPO‐OH signal induced by gp120. These data suggest the possible involvement of mannose‐specific endocytotic lectin of MDM. The reaction of DMPO with sodium nitroprusside, an organic nitrate that releases NO·, also produced DMPO‐OH. Our findings indicate that gpl20 increases free radical production from MDM as detected by spin‐trapping methods, and that the spin trap adduct results from a reaction involving NO· or closely related oxidized derivatives.

Evidence-informed practices in the real-world treatment of people with eating disorders

Although evidence-based interventions are effective for many eating disorder (ED) patients, realities surrounding ED treatment remain sobering: prognosis in the EDs is variable, and findings dictate that time-limited applications of our best-available treatments will leave around half of treatment “completers” symptomatic and needing something else or something more. (For full reviews see Couturier, Kimber, & Szatmari, 2013; Galsworthy-Francis & Allan, 2014; Groff, 2015; Hay, Bacaltchuk, & Stefano, 2004; Lock, 2015). This article offers suggestions aimed at helping ED therapists tailor their technique in principled ways to the realities of real-world treatment situations.
Effects of soil organic matter and ageing on remediation of diesel-contaminated soil

Bioremediation of diesel-contaminated soil was investigated for the effects of soil organic matter (SOM) and ageing time in two sets of experiments (Batch I and II, respectively). This study examined degradation efficiency in soil artificially contaminated with diesel oil (maximum total petroleum hydrocarbons (TPH) concentration of 9000 mg/kg soil). Batch I data showed that the values of the first-order degradation rate, k, were relatively high in the low-SOM soil batches. The quantity of SOM negatively correlated with the TPH degradation rates and with the total TPH degradation efficiency (%). Introduction of rhamnolipid to the soil proved to be a useful solution to resolve the problem of the residual TPH in the soil with high SOM. In Batch II, the k values decreased with the length of ageing time: 0.0245, 0.0128 and 0.0090 1/d in samples ST0 (freshly contaminated), ST38 (aged for 38 days) and ST101 (aged for 101 days), respectively. The TPH degradation efficiency (%) also decreased along with the ageing time. The research also applied molecular technology to analyse the bacterial community dynamics during the bioremediation course. Multivariate statistics based on terminal-restriction fragment length data indicated: 1) the soils with different SOM resulted in separate bacterial community structures, 2) ageing time created a variety of bacterial communities, 3) the bacterial community dynamics was associated with the hydrocarbon consumption. The SOM content in soils affected the TPH degradation rate and efficiency and the bacterial community structures. Aged soil is more difficult to remediate than freshly contaminated soil, and the resulting bacterial community was less dynamic and showed a lack of succession.
A methyl group controls conformational equilibrium in human mitochondrial tRNA(Lys).

The unmodified maturation intermediate in the biogenesis of human mitochondrial tRNALys adopts a nonfunctional conformation, resembling an extended hairpin. Single molecule fluorescence resonance energy transfer (FRET) studies reveal the additional presence of a small population in a functional cloverleaf conformation. Both conformations are in a dynamic equilibrium, interconverting on the 100 ms time scale. The post-transcriptional methylation of adenosine 9 to 1-methyladenosine is a crucial step in the biogenesis of the mature tRNA. This single methyl group, by disfavoring the nonfunctional conformation, shifts the observed equilibrium toward the functional cloverleaf and makes it available for further maturation. Here, single molecule FRET analysis makes dynamics and thermodynamics of these small RNAs conveniently accessible and elucidates the mode of action of a simple post-transcriptional modification.
S-restricted monotone alignments

We present an alignment algorithm for monotone many-to-many alignments, which are relevant e.g. in the field of grapheme-to-phoneme conversion (G2P). Moreover, we specify the size of the search space for monotone many-to-many alignments in G2P, which indicates that exhaustive enumeration is generally possible, so that some limitations of our approach can easily be overcome. Finally, we present a decoding scheme, within the monotone many-to-many alignment paradigm, that relates the decoding problem to restricted integer compositions and that is, putatively, superior to alternatives suggested in the literature.
Role of bonding, reduced screening, and structure in the high-temperature superconductors.

In this paper we have studied the role of bonding, reduced screening, and structure in high-temperature superconductors (HTSC) using La[sub 2]CuO[sub 4] as a prototype material. In addition to the ionic and metallic component of bonding recently investigated, we estimate the influence of covalence effects on the structural parameters and the phonon spectrum. Also, the effect of a reduced dispersion of the electronic band structure on the polarizability and the phonon frequencies is considered and (hypothetical) mechanisms are investigated, which would favor ferroelectricity in the HTSC. In a further topic we deal with reduced screening, introduced by nonadiabatic effects related to the quasi-two-dimensional band structure and its consequence for the electron-phonon interaction, the phonon dispersion, and the pairing mechanism. We then focus our interest on features related to the tetragonal-to-orthorhombic phase transition in La[sub 2]CuO[sub 4]. Structural parameters are calculated and the influence of the transition on the phonon dispersion as well as on the phonon-induced charge fluctuations is discussed. Finally, we present, on the basis of nonlocal electron-phonon interaction of the charge-fluctuation type, a theoretical interpretation of a universal relationship between [ital T][sub [ital c]] and the hole content in the HTSC.
Towards a self-healing, anti-jamming adaptive beamforming array

Fault tolerance is a critical property for many communication systems, whether it is commercial or governmental, related to defense or aerospace, be it terrestrial, airborne or in space. Redundancy is a common approach to fault-tolerance but incurs extra cost, mass, and overall system complexity. Self-healing systems are appealing because they avoid some of the disadvantages of redundancy while allowing the system to recover partial or full functionality. In this paper, we present experimental results showing how an adaptive beamforming system can recover full anti-jamming functionality in the presence of significant antenna damage.
Speech Emotion Recognition Using Transfer Learning

A major challenge for speech emotion recognition is that when the training and deployment conditions do not use the same speech corpus, the recognition rates will obviously drop. Transfer learning, which has successfully addressed the cross-domain classification or recognition problem, is presented for cross-corpus speech emotion recognition. First, by using the maximum mean discrepancy embedding (MMDE) optimization and dimension reduction algorithms, two close low-dimensional feature spaces are obtained for source and target speech corpora, respectively. Then, a classifier function is trained using the learned low-dimensional features in the labeled source corpus, and directly applied to the unlabeled target corpus for emotion label recognition. Experimental results demonstrate that the transfer learning method can significantly outperform the traditional automatic recognition technique for cross-corpus speech emotion recognition. key words: speech emotion recognition, transfer learning, cross-corpus, dimension reduction
Efficacy and safety of 1alpha-hydroxyvitamin D3 for prevention of parturient paresis.

Four trials involved intravenous or intramuscular injections of 1alpha-hydroxyvitavin D3 to test efficacy in preventing parturient paresis. Use of . 1 mg intravenously afforded total protection compared with an incidence of 33% (2/6) in controls. Intramuscular injections of . 1 mg in 2 ml propylene glycol and . 3, . 5, and 1.0 mg in 5 ml corn oil resulted in 0, 15.7, 20, and 0% incidence of parturient paresis compared with 33, 16.7, 37.5, and 37.5% incidence of parturient paresis in the controls. There was a rapid increase in serum calcium (12 to 24 h) in response to intravenous treatment, whereas the response to intramuscular injections was gradual but was maintained longer. To evaluate the safety of 1alpha-hydroxyvitamin D3, eight cows, two per treatment, were given intramuscular doses of . 5, 1.0, 1.5, or 3.0 mg (three 1.0 mg injections) in 5 ml corn oil. No clinical or pathological evidence of hypervitaminosis C or soft tissue calcification was found. Tissue taken from the injection site 15 days after last injection contained 3 to 38 IU vitamin D activity per 100 g wet tissue compared with control of 8 to 15 IU per 100 g. Total vitamin D activity of milk taken the 11th milking postpartum from cows receiving . 5 or 1.0 mg had a mean of 13.4 and 22.6 IU vitamin D activity per liter compared to 19 IU per liter for control milk. Milk from the 5th milking postpartum in the cows receiving . 5 mg had a mean activity of 14.5 IU per liter. Milk from animals slaughtered for retention studies had a mean activity of 22 IU per liter.
