Tire blow-out control for direct drive electric vehicles using reconfiguration of torque distribution and vertical load

This paper proposes a composite stability control strategy for tire blowout electric vehicle with explicit consideration of vertical load redistribution, subject to multi-constraints, uncertainty and redundant actuation. To readily implement system state and actuator increment constraints, a model predictive controller is designed to enhance vehicle stability performance and original lane keeping. Meanwhile, a sliding mode control-based longitudinal velocity controller is collaboratively proposed for maintaining the original longitudinal velocity after tire blowout in the freeway, which can reduce considerably the rear-end collision accidents. After that, a constrained weighting least square-based reconfigurable torque distributor is developed to realize the tracking of the virtual resultant yaw-moment and longitudinal tire force signals generated by the above controllers, considering system physical constraints and actuator capability simultaneously. Simulations with different tire blowout scenarios are conducted on the developed dynamic simulation platform to demonstrate the effectiveness of the designed control methods; furthermore, the influence of different tire blowout on the vehicle movement behaviors is discussed. Statistical results based on the system transient performance and control effort evaluating indictors highlight the considerable superiority of the developed model predictive controller compared with the linear quadratic regulator.
Demand and Supply Analysis of Transport Energy in Pakistan

Over the last decade, the importance of energy consumption in transport sector has burgeoned forth and has been growing rapidly in Pakistan, and the course is being augured to linger over the coming decades. This paper brings about the function of transport energy demand, economic growth (GDP), oil rents, gas rents, road length and number of registered vehicles for Pakistan over the 1980-2015 by using Autoregressive Distributive Lag (ARDL) approach. The results which have had come about shows preponderance of the fact that there is powerful relationship between all concerned variables when transport energy demand is used as a dependent variable in Pakistan. Hence, Autoregressive Integrated Moving Average (ARIMA) model is used for the future forecasting related to the consumption and production of gasoline and oil. According to the forecasted results, consumption (demand) is much greater as compared to production (supply) in both non-renewable sources. As policy makers suggest, we can make up for this lacuna by bourgeoning forth new technology (hybrid vehicles) as well as an awareness campaign through which we can make others abreast of this research may be launched about energy conservation methods to curtail the transport energy demand (TED) in the country.

XSlit cameras for free navigation with depth image-based rendering

In free navigation applications, any viewpoint to a three-dimensional scene can be synthesized through Depth Image-Based Rendering (DIBR). In this paper we show that XSlit cameras achieve up to 3 dB PSNR gain over conventional pinhole camera arrays when synthesizing virtual views to the scene with DIBR for small camera displacements. XSlit cameras are a type of general linear cameras where the light rays pass through two non-intersecting slits instead of a single point (the optical center of conventional cameras), resulting in a different epipolar geometry and projection equations. Instead of synthesizing virtual views with DIBR from a set of conventional pinhole cameras, e.g. a stereo camera pair, a single XSlit camera exploits the distance between its slits and their relative rotation to obtain disparity, out of which DIBR virtual views can be synthesized. We first present a theoretical study to present the parameters of XSlit cameras, different from pinhole cameras, at the same time making sure that the XSlit camera is physically implementable. We then validate the study with DIBR achieved on synthetic content using perfect depth maps obtained from an in-house modified version of Blender’s engine Cycles to simulate XSlit cameras. The virtual view synthesis uses an adapted version of the Reference View Synthesis software used in MPEG, the worldwide standardization committee for media compression. Our experiments show that for the same overall space covered by the studied camera architectures, XSlit cameras often obtain better DIBR view synthesis results, with up to 3 dB PSNR gain.
Attitudes Towards People with Disabilities: The Turkish Version of the Disability Attitudes in Health Care Scale

ABSTRACT This study aimed to carry out the Turkish adaptation of the Disability Attitudes in Health Care Scale (DAHC). A total of 283 medical students were recruited. Data was collected using a sociodemographic information form, the Turkish version of the DAHC, and the Disability Attitudes Scale (DAS). Reliability and validity of the DAHC was estimated using Cronbach’s alpha, item-total correlations, exploratory and confirmatory factor analyses, and Pearson correlation. Examination of item-total correlations pertaining to the DAHC led to the exclusion of two items. Exploratory factor analysis of the 15-item Turkish DAHC yielded a two-factor solution. Confirmatory factor analysis supported the existence of two related factors, namely Burden and Inclusion. Internal consistency of the DAHC was deemed satisfactory. Total DAHC score had a moderate positive correlation with the DAS, providing evidence for criterion validity. Females held more positive attitudes compared to males. It was concluded that the Turkish version of the DAHC is a valid and reliable measure which can be used for evaluating attitudes towards people with disabilities in healthcare professionals.
Study of Osteomyelitis in paediatric patients

Introduction: Osteomyelitis is defined as inflammation of bone. Though the main culprits are bacteria occasionally fungi may also be involved. Prognosis of untreated or delayed treatment onset osteomyelitis is often bad and leads to adverse outcomes. Very few cases of osteomyelitis are reported from India as compared to other infectious conditions. In this study we aim to study the number of patients, male: female ratio, type of osteomyelitis and the bacterial profile associated with osteomyelitis. Methods: After obtaining Institutional Ethics approval, the present study was conducted from 1st January 2016 - 31st December 2016 at KVG Medical College, Sullia. Blood and sample like fluid aspirate or discharge collected was subjected to microscopy and culture. Antibiotic susceptibility testing was done using disk diffusion methods. Radiological data of the patients was also collected. Results: Bacteria were isolated from 32 cases. The most affected age group was of 6-10 years of age (46.87%). Males were more affected as compared to females and male: female ratio was 3:1. Maximum number of patients were of acute osteomyelitis (87.5%) followed by subacute osteomyelitis (9.38%) and chronic osteomyelitis was found in just a single patient (3.12%). Long bones like tibia (56.25%), femur (18.75%), humerus (12.5%) were mostly affected. Blood culture was positive in 65.62% cases. Methicillin Sensitive Staphylococcus Aureus (MSSA) was the most common isolate (56.25%) followed by, Methicillin Resistant Staphylococcus Aureus (MRSA), Acinetobacter, Coagulase Negative Staphylococcus (CONS), Streptococcus pyogens, E.coli and Pseudomonas. Conclusion: Thus, S. aureus was the most common cause of acute bacterial osteomyelitis and mostly affected school age group children.
Application of VMD and Hilbert Transform Algorithms on Detection of the Ripple Components of the DC Signal

Accurate detection of ripple components of the direct-current (DC) signals is essential for evaluating DC power quality. In this study, the combination algorithm based on variational mode decomposition (VMD) and Hilbert transform (HT) is applied to detect and analyze the characteristics of the ripple components of the DC disturbance signals. Firstly, the optimal modal number of VMD algorithms is comprehensively determined by observing the center frequencies of the mode components and the Index of Orthogonality (IO) of mode components. Through utilizing the VMD algorithm, the DC disturbance signal is accurately decomposed into a series of amplitude modulation-frequency modulation (AM-FM) functions. Then, the HT algorithm is applied to each AM-FM function to obtain the corresponding instantaneous amplitude and frequency, and the characteristics of DC disturbance signal are determined. Some case studies are implemented to analyze the ripple components of the DC disturbance signal with the VMD-HT and empirical mode decomposition (EMD) algorithm. Finally, the experiment results of Gree Photovoltaic Cabin have verified the feasibility and effectiveness of the proposed combination VMD-HT algorithm by comparison with EMD and the window interpolation fast Fourier transform (WIFFT) algorithms.
A Model-Based Method for Predicting the Shapes of Planar Single-Segment Continuum Manipulators With Consideration of Friction and External Force

The shape prediction of tendon-driven continuum manipulators is a challenging problem due to the effect of inner friction and external force. Many researchers use actuation displacement or actuation force as model input to predict the shapes of manipulators, but very few consider their relations and models able to predict the status of friction. This paper proposes a model-based method that combines the mechanics model with the kinematic model to predict the shapes of planar single-segment manipulators with consideration of external force and friction. Finally, the shape prediction of manipulators is converted to an optimization problem with actuation displacement and actuation force as the inputs of our algorithm. The distribution of tendon force and the situation of friction can be calculated by using the feedback data of the actuation unit even when actuation direction changes and hysteresis occurs. Experimental results indicate that the method has good performance in predicting the manipulator’s shapes.
The effect of menstrual phase and oral contraceptive steroids on caffeine during cycling performance

PURPOSE: There is evidence that female sex hormones impact caffeine metabolism, with decreased CYP1A2 activity and diminished caffeine clearance in women with higher estrogen levels. Therefore, the objectives of this project were to determine the effects of oral contraceptives and menstrual cycle on the benefits of caffeine supplementation for cycling performance. METHODS: Sixteen recreationally trained female cyclists, oral contraceptive steroid (OCS) users (n=8, age = 21.4 ±1.4 years, height = 168.4 ± 3.6 cm, weight = 63.6 ± 7.2 kg, VO2max = 48.0 ± 4.0 mlkg-1min-1) and non-users (n=8, age = 20.9 ± 2.1 years, height = 161.0 ± 7.7 cm, weight = 59.5 ± 9.2 kg, VO2max = 50.9 ± 7.8 mlkg-1min-1), completed four separate computersimulated 3-km cycling time trials (TT). Subjects ingested either 6mg/kg of caffeine or a placebo capsule one hour prior to each trial. Magnitude based inferences were used to evaluate treatment effects. RESULTS: Caffeine enhanced 3-km TT performance (compared to placebo) in early (‘possibly’) and late (‘very likely’) phases of the menstrual cycle for OCS users by 1.6 ± 2.1% and 2.7 ± 1.4% respectively. Likewise, caffeine enhanced 3-km TT performance in early and late (‘likely’) phases of the menstrual cycle for non-users by 2.6 ± 2.3% and 2.1 ± 2.2%. All other comparisons for OCS users and non-users were ‘unclear’. CONCLUSIONS: Caffeine supplementation improved 3-km TT finishing time and average power output in follicular and luteal phases of the menstrual cycle, with unclear effects between the phases for both OCS users and non-users. This indicates that menstrual status is not a significant source of variability on the ergogenic effect of caffeine supplementation on cycling performance.
The impact of progestin-only contraception on weight change in the first postpartum year

Objectives: To investigate the impact of the etonogestrel implant (ENG-IMP) and depot-medroxyprogesterone acetate (DMPA) on weight loss in non-breastfeeding women during the first postpartum year. Study Design: We designed a modified randomized controlled trial of immediately postpartum, non-breastfeeding women. Sixty six women were randomized to receive either the ENG-IMP or DMPA prior to discharge from the hospital. Thirty four women choosing to leave the hospital without initiating a contraceptive method served as a comparison group. The primary outcome of weight loss, both absolute and percent, was computed, and compared among groups over time during the first postpartum year. Secondary outcomes included contraceptive continuation and satisfaction. Results: At 3 months postpartum, mean weight loss for ENG-IMP users was 8.1% (6.5 kg), DMPA users lost 2.2% (2.0 kg), and the comparison group lost 8.2% (6.5 kg). The difference in percent weight change at 3 months between DMPA users and both ENG-IMP users and the comparison group was statistically significant (p=0.007, p=0.02 respectively). At 6 and 12 months, there were no statistically significant weight loss differences between groups. Randomized women had high rates of satisfaction (“good” or “very good” for 88% of ENG-IMP users, and 89% of DMPA users) and continuation (89% of ENG-IMP and 73% of DMPA users) at 12 months. Conclusions: By three months postpartum, women using the ENG-IMP had lost more weight than DMPA users, but the difference was not sustained at 12 months. Implications: Providers should inform women not breastfeeding in the postpartum period that early administration of DMPA may decrease initial weight loss relative to implant users and those getting DMPA later, though weight loss at 12 months postpartum may be the same among all groups. This study highlights the relatively small weight losses in the postpartum period among all groups and indicates the need for education and programs to encourage postpartum weight loss in this population.
Brain Science and Brain-inspired Artificial Intelligence: Advances and Trends

They have a wide range of applications including military and defense, intelligent manufacturing, business intelligence and management, medical service and healthcare, etc. Many countries have launched national brain-related projects to increase the national interests and capability in the competitive global world. In this paper, we introduce some concepts, principles, and emerging technologies of brain science and brain-inspired artificial intelligence; present their advances and trends; and outline some challenges in brain-inspired computing and computation based on spiking-neural-networks (SNNs). Specifically, the advances and trends cover brain-inspired computing, neuromorphic computing systems, and multi-scale brain simulation, brain association graph, brainnetome and the connectome, brain imaging, brain-inspired chips and brain-inspired devices, brain-computer interface (BCI) and brain-machine interface (BMI), brain-inspired robotics and applications, quantum robots, and cyborg (human-machine hybrids).
Perioperative Preceptor Education in an Agency Preceptor Workshop

There is a critical shortage of perioperative nurses and the demand in the United States (US) is growing steadily by 1% to 2% each year. It is estimated that nearly 20% of registered nurses (RNs) currently working in the perioperative area will retire in the next five years. In the perioperative area, when using the 6 to 12-month orientation time frame, as outlined in the Association of PeriOperative Registered Nurses (AORN) orientation calculator, the cost of orienting a new RN can exceed $100,000. A preceptorship workshop is one strategy that has been shown as an evidence-based intervention to decrease RN turnover rates, increase job satisfaction, and have a positive effect on new nurse role transition and intent to stay. Perioperative preceptor education as a component of an agency-wide workshop was developed and implemented with the purpose to improve RN preceptor performance and proficiency, and increase perioperative RN orientee satisfaction and intent to stay. A preand post-intervention design was implemented in a 391-bed Magnet designated facility to evaluate these outcomes. Using eta square, mean preceptor performance and proficiency scores indicated a moderate effect size, which demonstrated clinical significance and a positive impact on the nurse practice environment.
