Design tool for development and performance analysis of omni-directional AGVs

This document serves to discuss the creation, and use of software targeted at designing and optimising swerve drive AGVs. Specifically relating to design calculations such as drive train design, suspension design and power systems requirements to fast track implementation of task specific AGVs. It is hoped that software such as this can be implemented in the design process to streamline design tasks and eliminate “by hand” iterative calculations so as to significantly reduce design time.
Fathers’ Experience of Parenting a Child With Juvenile Rheumatoid Arthritis

The author examined the experience of fathers who have a child with juvenile rheumatoid arthritis (JRA). He used grounded theory methodology, in which 22 fathers participated in semistructured interviews, and developed a substantive theory of fathers’ experience that addresses the impact of their child’s JRA, their adaptational responses, and the meanings they associated with their experiences. Fathers were profoundly affected, perceived their child’s condition as a catalyst for meaningful involvement, experienced many emotions, and sought to adopt a positive approach to making sense of their child’s condition. Fathers’efforts to be strong for others resulted in an overreliance on self-support strategies, particularly during periods of high stress. Given the nature of fathers’ experience and the extent of their involvement, greater attention by health care practitioners to fathers’ adaptation is indicated.
A small-scale cherrypicker for experimental and educational use

Cherrypickers are a useful class of machines that lift people to great heights. However, a major drawback of cherrypickers is that they oscillate when they move. Under-standing the dynamics and stability of these machines is crucial for efficient and safe operation. To this end, a small-scale cherrypicker was constructed for experimental dynamic analysis and educational use. Experimental results confirm the benefits of the vibration-control techniques developed for this machine. The cherrypicker was used during Fall 2010 as an experimental apparatus in an advanced graduate controls course taught simultaneously at the Georgia Institute of Technology and the Massachusetts Institute of Technology. Details of its educational use are discussed.
Development and Validation of a Measure Assessing Child Diabetes Behavior: The Diabetes Behavior Checklist

ABSTRACT Previous research in pediatric diabetes management has focused on general child behavior, which is linked with treatment adherence and health outcomes in children with type 1 diabetes. Little is known about child diabetes behavior problems specifically. The current study aimed to develop and validate a measure of diabetes-specific child behavior problems, and parents’ confidence in managing these behaviors. Participants were a community sample of 186 parents of children aged 2–10 years with type 1 diabetes, recruited via online parenting forums and advertisements placed in school and childcare newsletters throughout Australia. The measure demonstrated excellent internal consistency and evidence of construct validity, and factor analyses revealed a 3-factor and a 1-factor structure for the Extent and Confidence scales, respectively. This study provides preliminary evidence of validity of the Diabetes Behavior Checklist. The implications of these findings for intervention development are discussed.
Fix and float: object movement by egocentric navigation

c The two traditional techniques for moving objects in graphical workspaces are dragging and cut and paste. Each method has some disadvantages. We introduce a new method, calledfixandfloat, formoving objects in graphical workspaces. The new methodfies the object(s) to the gaze or viewpoint, thereby letting the user move objects implicitly while,doing egocentric navigation. We describe the advantages this new method has over previous techniques, and give an example of its use in a 3D graphical workspace. )’ . :,
A maternal high-fat diet during pregnancy and lactation, in addition to a postnatal high-fat diet, leads to metabolic syndrome with spatial learning and memory deficits: beneficial effects of resveratrol

We tested the hypothesis that high-fat diet consumption during pregnancy, lactation, and/or post weaning, altered the expression of molecular mediators involved in hippocampal synaptic efficacy and impaired spatial learning and memory in adulthood. The beneficial effect of resveratrol was assessed. Dams were fed a rat chow diet or a high-fat diet before mating, during pregnancy, and throughout lactation. Offspring were weaned onto either a rat chow or a high-fat diet. Four experimental groups were generated, namely CC, HC, CH, and HH (maternal chow diet or high-fat diet; postnatal chow diet or high-fat diet). A fifth group fed with HH plus resveratrol (HHR) was generated. Morris water maze test was used to evaluate spatial learning and memory. Blood pressure and IPGTT was measured to assess insulin resistance. Dorsal hippocampal expression of certain biochemical molecules, including sirtuin 1, ERK, PPARγ, adiponectin, and BDNF were measured. Rats in HH group showed impaired spatial memory, which was partly restored by the administration of resveratrol. Rats in HH group also showed impaired glucose tolerance and increased blood pressure, all of which was rescued by resveratrol administration. Additionally, SIRT1, phospho-ERK1/2, and phospho-PPARγ, adiponectin and BDNF were all dysregulated in rats placed in HH group; administration of resveratrol restored the expression and regulation of these molecules. Overall, our results suggest that maternal high-fat diet during pregnancy and/or lactation sensitizes the offspring to the adverse effects of a subsequent high-fat diet on hippocampal function; however, administration of resveratrol is demonstrated to be beneficial in rescuing these effects.
Reliability Evaluation of Distributed Generation Based on Operation Mode

This paper presents an analytical technique for evaluating the reliability of a distribution system, including distributed generation. Unlike the large-scale generation of the transmission system, distributed generation (DG) creates difficulties in evaluating reliability indices due to the complexity of the operation status. Explicit expressions for analyzing the reliability of distributed generation are proposed in this paper. The technique proposed includes the characteristics of DG, such as operation mode to mix peaking and standby modes and the failure of starting and DG itself
Subinhibitory concentrations of antibiotics affect cell surface properties of Streptococcus sobrinus

Several antibiotics, at subinhibitory concentrations, caused an increase in the ability of Streptococcus sobrinus to bind alpha-1,6-glucans, whereas other antibiotics decreased glucan binding. In every case, glucan binding was inversely proportional to cell surface hydrophobicity. High levels of glucan-binding activity resulted in low levels of hydrophobicity, whereas low levels of glucan binding caused high levels of cellular hydrophobicity. The results show that low concentrations of antibiotics may modulate lectin and hydrophobin adhesins in streptococci.
Remote Sensing Satellite Image Fusion Using Fast Curvelet Transforms

This paper presents a novel fusion rule via high pass modulation using Local Magnitude Ratio (LMR) in Fast Discrete Curvelet Transforms (FDCT) domain. It is based on the Fourier and wavelet transform methods , which retain rich multispectral details but less spatial details from source images. Wavelets perform well only at linear features but not at non linear discontinuities because they do not use the geometric properties of structures. Curvelet transforms overcome such difficulties in feature representation. In this method Indian Remote Sensing (IRS) Resourcesat-1 LISS IV satellite sensor image of spatial resolution of 5.8m is used as low resolution (LR) multispectral image and Cartosat-1 Panchromatic (Pan) of spatial resolution 2.5m is used as high resolution (HR) Pan image. This fusion rule generates HR multispectral image at 2.5m spatial resolution. The method has been compared with values obtained from different techniques such as Wavelet, Principal component analysis (PCA), High pass filtering(HPF), Modified IntensityHue-Saturation (M.IHS) and Grams-Schmidth fusion methods. Some experimental results and conclusions about the performance of the method are presented.
A twin-family study of alcoholism in women.

OBJECTIVE The authors seek to understand in general the sources of familial resemblance for alcoholism and in particular how parents transmit the vulnerability to alcoholism to their daughters. METHOD The authors interviewed 1,030 pairs of female same-sex twins of known zygosity from the population-based Virginia Twin Registry and 1,468 of their parents. They examined a narrow definition of alcoholism, requiring tolerance or dependence, and a threshold approach that classified individuals either as unaffected or as suffering from one of three levels of severity of alcohol-related problems. Twin-family structural equation models were fitted to the observed tetrachoric or polychoric correlation matrices by using asymptotic weighted least squares. RESULTS In the best-fitting model from both diagnostic approaches, 1) the familial resemblance for alcoholism was due to genetic factors, with the heritability of liability estimated at 51% to 59%; 2) genetic vulnerability to alcoholism was equally transmitted to daughters from their fathers and from their mothers; and 3) alcoholism in parents was not environmentally transmitted to their children. Assortative mating for alcoholism was found only for the broader definitions of illness. Genetic factors that influenced the liability to alcoholism were the same in the parental and twin generation for the narrow definition of alcoholism. When broader definitions were used, these factors, while substantially correlated, were not identical. CONCLUSIONS The transmission of the vulnerability to alcoholism from parents to their daughters is due largely or entirely to genetic factors.
Factorial dimensions obtained with the Eating Disorder Inventory (EDI) and the Karolinska scales of Personality (KSP) in women having Anorexia Nervosa or Bulimia Nervosa as related to clinical and to other characteristics

Sixty women, 19 with Anorexia Nervosa (AN) and 41 with Bulimia Nervosa (BN), were given the Eating Disorder Inventory (EDI) and the Karolinska Scales of Personality (KSP). The aim was by means of factor analysis of the 23 variables from these questionnaires to determine certain descriptive dimensions and relate them to symptoms and to diagnoses, as well as to signs based on results of the Defense Mechanism Technique modified (DMTm) and to the distribution of the women within five subgroups, two of these anorexic and three bulimic, as described in Wilhelmsson and Andersson (2005). The six factors found were referred to as those of somatic distress, unsatisfactory feelings, dissatisfaction with the body, interpersonal insecurity, need for change and aggressiveness. The most clear-cut findings were that personality disorder was related to high scores on unsatisfactory feelings and somatic distress and to low scores on need for change. High Body Mass Index (BMI) results were found to be associated with high scores on dissatisfaction with the body, and occurrence of a restricting anorexic type to be associated with low scores of the latter. The DMTm signs of H-repression and H afraid were found to be related to high scores on somatic distress, the occurrence of barrier isolation to high scores on unsatisfactory feelings, and the occurrence of affect anxiety to high scores on interpersonal insecurity. Differences between the subgroups were found for somatic distress, unsatisfactory feelings, dissatisfaction with the body and interpersonal insecurity.
Effectiveness of Fibrin Glue in Adherence of Skin Graft

Background: Graft fixation is important for graft take. Fibrin glue has been proposed as an ideal material, because of its human origin and it provides firm adhesion in seconds or minutes. Objective: To evaluate the efficiency of fibrin glue, in increasing the take of skin graft. Assessment includes surgical time taken for graft fixation, haematoma/seroma formation, engraftment and wound closure by day 14. Methods: The study is an observational prospective study conducted in the Department of Plastic Surgery, Jawaharlal Institute of Postgraduate Medical Education and Research, Puducherry, from January 2016 to June 2016. Sixteen patients who underwent split skin grafting were assessed during the study period. Fibrin glue was used on the recipient bed before grafting. Results: Better haemostasis and graft adhesion, with a significant reduction of surgical time, were noted. Conclusion: The safety profile of fibrin glue was excellent as indicated by the lack of any related serious adverse experiences. These findings demonstrate that it is safe and effective for attachment of skin grafts, with outcomes at least as good as conventional methods.

Effects of the aromatase inhibitor letrozole on in utero development in rats.

BACKGROUND The aromatase inhibitor letrozole has recently been identified as a promising ovulation-inducing agent. As information regarding possible adverse effects on gestation outcome is limited, the present study was undertaken to evaluate the developmental toxicity potential of letrozole in the rat. METHODS Pregnant Sprague-Dawley rats were exposed via drinking water to letrozole at 0 (control group), 0.01, 0.02, or 0.04 mg/kg during the period of organogenesis. Developmental endpoints, including intrauterine mortality, fetal growth and incidence of structural abnormalities, were evaluated near the end of gestation. RESULTS Major treatment-related effects included: (i) a dose-dependent increase in post-implantation loss, which reached 47.2% following exposure to 0.04 mg/kg letrozole; (ii) minor vertebral anomalies affecting 32.2, 29.3 and 42.2% of fetuses exposed to 0.01, 0.02 and 0.04 mg/kg, respectively. CONCLUSION Gestational exposure to doses of letrozole that are equal to or lower than the daily recommended human dose has toxic effects on prenatal development in rats.
Three-Dimensional Morphological Characterization of Optic Nerve Fibers by Atomic Force Microscopy and by Scanning Electron Microscopy

A comparative study of scanning electron microscopy (SEM) and atomic force microscopy (AFM) imaging of the healthy human optic nerve was carried out to determine the similarities and the differences. In this study we compared the fine optic nerve structures as observed by SEM and AFM. The fibers of the right optic nerve of a 61-year-old man show different arrangements in transverse sections taken from the same individual 5 mm central to the optic canal and 5 mm peripheral to the optic chiasma; this difference can be recognized by light microscopy (LM), SEM, and AFM. AFM revealed such typical optic nerve fibers (taken from a point 5 mm central to the optic canal) with annular and longitudinal orientations, which were not visible by SEM in this form. By contrast, LM and SEM visualized other structures, such as pia mater and optic nerve fibers loosely arranged in bundles, none of which was visualized by AFM. The images, however, taken 5 mm peripheral from the optic chiasma show shapeless nerve fibers having a wavy course. Our results reveal that more detailed information on optic nerve morphology is obtained by exploiting the advantages of both SEM and AFM. These are the first SEM and AFM images of healthy human optic nerve fibers, containing clear representations of the three dimensions of the optic nerve.
Tour Route Recommendation Begins with Multimodal Classification

Location estimation of tourist photos by classifi­cation is challenging due to the unstable and less-discriminative features of photos taken in each city. In this paper, we originally deal with this issue in an alternative way, which begins with but is not limited to classification. We explore textual, temporal, geographic as well as visual information to make tour route recommendation. Given a query photo, we recommend a city by first classifying the photo to get scores that indicate its similarities with photos from each city, and then evaluating the attractiveness of each city by modeling its hotness potential. We do not aim at finding out where the photo was taken exactly; instead, we combine the similarity and hotness potentials according to the user’s preference and recommend the city that has the highest combination value. Then, we suggest the next city by further modeling the correlation and interaction between cities pairwise with two potentials, i.e., proximity and co-visitedness. Applying the greedy algorithm, we recommend one city at a time and eventually generate a tour route consist­ing of all the recommended cities in order. Furthermore, in order to show different visual and cultural character­istics across cities, we classify photos of each city into four categories, i.e., food, landscape, man-made and person. In experiments, we collected a database containing 41792 photos of 35 important cities along the silkroad and provided a query sample for tour route recommendation. Experimental results have shown the effectiveness and reliability of our recommendation model.
Distribution of p 53 codon 72 polymorphism in Indian primary open angle glaucoma patients

Glaucoma is a complex neurodegenerative disorder of the eye and can affect all ages. It is estimated that approximately 70 million people worldwide suffer from glaucoma. Untreated, glaucoma is a leading cause of irreversible blindness. Some of the ‘risk factors’ may be inherited to a variable extent. Primary Open Angle Glaucoma (POAG) is the most common type of glaucoma, accounting for over half of the total cases. A positive family history of glaucoma is a significant risk factor for the disease. At least two genes, MYOC and optineurin [1,2], and 4 other chromosomal loci has been linked to POAG [3-6]. In addition, intraocular pressure, ethnicity, some aspects of vascular function, and high refractive error are major risk factors [7]. It has been proposed that the death of ganglion cells by apoptosis represents a common pathway that leads to glaucomatous vision loss [8-10]. However, the mechanism of ganglion cell apoptosis is not well understood. The suggestion that ganglion cell death in glaucoma is apoptotic comes from a lack of any demonstration of cell necrosis rather than evidence of apoptosis [11]. Lin and colleagues have argued that genomic instability of p53 in other disease processes suggests its possible role in the glaucomatous neuropathy as well [12]. High levels of expression of p53 in normal rodent and murine ocular tissues have also been reported [13-16]. To resolve the suspected role of p53 in glaucomatous neuropathy Lin et al. [12] investigated the role of p53 codon 72 polymorphism which changes arginine (Arg) to proline (Pro) due to a G to C transversion, and observed significant difference in the distribution of the polymorphism between the control subjects and the Chinese POAG patients. It has been reported that the frequency of the Pro allele is significantly higher in the POAG group and the Pro form of p53 codon 72 increases the risk of developing POAG in Chinese people. This polymorphism has been subject to many epidemiological studies that explore the possible association of this polymorphism with risk of different cancer types [17]. However, the results of the epidemiological studies remained inconclusive; some exhibited strong association while others did not © 2002 Molecular Vision
PrPSc Is Not Detected in Peripheral Blood Leukocytes of Scrapie-Infected Sheep: Determining the Limit of Sensitivity by Immunohistochemistry

ABSTRACT Peripheral blood leukocytes (PBLs) from scrapie-infected sheep were evaluated for the presence of PrPSc by using dissociated retropharyngeal lymph node (DRLN) cells and immunohistochemistry (IHC). PrPSc-positive cells were detected in 2.05% ± 0.28% of 3 × 106 DRLN cells, but were not detected in 3 × 106 PBLs from scrapie-infected sheep. Titration of DRLN cells mixed with PBLs showed that IHC detects a minimum of 0.00205% or 60 PrPSc-positive cells in 3 × 106 PBLs.

AN ABSTRACT OF THE THESIS OF Thai Duong for the degree of Master of Science in Computer Science presented on May 20, 2015. Title: Data Collection in Sensor Networks via the Novel Fast Markov Decision Process Framework Abstract approved:

approved: Thinh P. Nguyen We investigate the data collection problem in sensor networks. The network con­ sists of a number of stationary sensors deployed at different sites for sensing and storing data locally. A mobile element moves from sites to sites to collect data from the sensors periodically. There are different costs associated with the mo­ bile element moving from one site to another, and different rewards for obtaining data at different sensors. Furthermore, the costs and the rewards are assumed to change abruptly. The goal is to find a ”fast” optimal movement pattern/policy of the mobile element that optimizes for the costs and rewards in non-stationary environments. We formulate and solve this problem using a novel optimization framework called Fast Markov Decision Process (FMDP). The proposed FMDP framework extends the classical Markov Decision Process theory by incorporating the notion of mixing time that allows for the trade-off between the optimality and the convergence rate to the optimality of a policy. Theoretical and simulation results are provided to verify the proposed approach.
Design and Performance Analysis of Millimetre-Wave Rotman Lens-Based Array Beamforming Networks for Large-Scale Antenna Subsystems

This paper presents the comprehensive analytical design and numerical performance evaluation of novel millimetre-wave (mm-wave) switched-beam networks, based on the Rotman lens (RL) array feeding concept. These passive array devices have been designed for operation in the 28GHz frequency band, covering the whole 18–38 GHz frequency range. The primary objective of the work is to conduct a thorough feasibility study of designing wideband mm-wave beamformers based on liquid-crystal polymer (LCP) substrates, to be potentially employed as low-cost and high-performance subsystems for the advanced transceiver units and large-scale antennas. The presented RLs exhibit significant output behaviours for electronic beam steering, in terms of the scattering (S) parameters, phase characteristics, and surface current distributions, as the feeding systems’ primary functionality indicators.
