In this paper, a stochastic nonlinear model predictive control (S-NMPC) approach has been illustrated for the energy management of a battery/SC hybrid energy storage systems (HESSs) in a Toyota Rav4EV. As the performance of predictive controllers in these systems is highly dependent on the future power demand estimation, a stochastic approach has been adopted in order to include uncertainties in the driver's power demand prediction, exploiting the ideas of the two-stage stochastic programming method. The power demand is modeled as a Markov chain and has been trained with several standard and real-world driving cycles. Model-in-the-Loop (MIL) simulation results have been presented over a driving cycle different from that used as training data. The results of the S-NMPC method has been compared against other deterministic approaches.

Despite substantial declines since 2000, lower respiratory infections (LRIs), diarrhoeal diseases, and malaria remain among the leading causes of nonfatal and fatal disease burden for children under 5 years of age (under 5), primarily in sub-Saharan Africa (SSA). The spatial burden of each of these diseases has been estimated subnationally across SSA, yet no prior analyses have examined the pattern of their combined burden. Here we synthesise subnational estimates of the burden of LRIs, diarrhoea, and malaria in children under-5 from 2000 to 2017 for 43 sub-Saharan countries. Some units faced a relatively equal burden from each of the three diseases, while others had one or two dominant sources of unit-level burden, with no consistent pattern geographically across the entire subcontinent. Using a subnational counterfactual analysis, we show that nearly 300 million DALYs could have been averted since 2000 by raising all units to their national average. Our findings are directly relevant for decision-makers in determining which and targeting where the most appropriate interventions are for increasing child survival. © 2022, The Author(s).

Recently, there has been a growing interest in integrating NMPC in automotive applications in order to make driving more intelligent and ecological. One major challenge in the way of developing Nonlinear Model Predictive Controllers for automotive systems is to reach sub-millisecond computation times for real-time applications. C/GMRES and Newton/GMRES are fast optimization methods demonstrating promising results. This paper develops an Ecological Cruise Control for a Plug-in Hybrid Electric Vehicle, and then presents a comparison between the two aforementioned optimizers in terms of accuracy and speed. Simulation results tested on a high-fidelity model of Toyota Prius in Autonomie identify C/GMRES method slightly faster than Newton/GMRES method with approximately the same accuracy in the solution.

Background: Persuasive design is an approach that seeks to change the behaviors of users. In primary care, clinician behaviors and attitudes are important precursors to structured data entry, and there is an impact on overall data quality. We hypothesized that persuasive design changes data-entry behaviors in clinicians and thus improves data quality. Objective: The objective of this study was to use persuasive design principles to change clinician data-entry behaviors in a primary care environment and to increase data quality of data held in a family health team’s reporting system. Methods: We used the persuasive systems design framework to describe the persuasion context. Afterward, we designed and implemented new features into a summary screen that leveraged several persuasive design principles. We tested the influence of the new features by measuring its impact on 3 data quality measures (same-day entry, record completeness, and data validity). We also measured the impacts of the new features with a paired pre-post t test and generated XmR charts to contextualize the results. Survey responses were also collected from users. Results: A total of 53 users used the updated system that incorporated the new features over the course of 8 weeks. Based on a pre-post analysis, the new summary screen successfully encouraged users to enter more of their data on the same day as their encounter. On average, the percentage of same-day entries rose by 10.3% for each user (P<.001). During the first month of the postimplementation period, users compensated by sacrificing aspects of data completeness before returning to normal in the second month. Improvements to record validity were marginal over the study period (P=.05). Statistical process control techniques allowed us to study the XmR charts to contextualize our results and understand trends throughout the study period. Conclusions: By conducting a detailed systems analysis and introducing new persuasive design elements into a

Medical images can be a valuable resource for reliable information to support medical diagnosis. However, the large volume of medical images makes it challenging to retrieve relevant information given a particular scenario. To solve this challenge, content-based image retrieval (CBIR) attempts to characterize images (or image regions) with invariant content information in order to facilitate image search. This work presents a feature extraction technique for medical images using stacked autoencoders, which encode images to binary vectors. The technique is applied to the IRMA dataset, a collection of 14,410 x-ray images in order to demonstrate the ability of autoencoders to retrieve similar x-rays given test queries. Using IRMA dataset as a benchmark, it was found that stacked autoencoders gave excellent results with a retrieval error of 376 for 1,733 test images with a compression of 74.61%. © Springer International Publishing AG 2016.

This paper proposes a model predictive control (MPC) scheme for the battery thermal management system (BTMS) of a given plug-in hybrid electric vehicle, namely the Toyota Plug-in Prius. As temperature plays a key-role in battery life and performance, BTMS design has become a critical problem in all of the battery-based technologies. Although BTMS control design in its basic form can be well represented by a reference tracking problem, there exists only little research in the literature addressing this important control problem. Due to the importance of a prediction component in thermal systems, the idea in this paper is to design a concrete BTMS controller using the nonlinear model predictive control (NMPC) theory and examine its applicability to fill this gap. The promising simulation results indicate the prosperity of the proposed BTMS control methodology and thus pave the way for use of the model-based thermal management techniques in a wide range of upcoming battery-based devices.

An inverse problem approach to computational active depth from defocus

Journal of Physics: Conference Series 2018年第1期1047卷

作者： A Ma A Wong Vision and Image Processing Lab Systems Design Engineering University of Waterloo 200 University Ave W Waterloo ON N2L 3G1

A novel methodology for inferring depth measurements using active quasi-random colored point projection patterns is presented by recourse to computational inverse modelling within the context of depth from defocus. The forward problem is considered that when capturing objects using a camera, light reflected off of objects at different depths will result in blurry observations in the acquired image, whereas the inverse problem seeks to estimate the depth from the knowledge of the blurry observations. In the proposed approach, a colored quasi-random point projection pattern is projected onto the scene of interest, and each projection point in the image captured by a cellphone camera is analyzed using an inverse model to estimate the depth at that point. The proposed method has a relatively simple setup, consisting of a camera and a projector, and enables depth inference from a single capture. We conclude with qualitative and quantitative results that highlight the strong potential for enabling active depth sensing in a simple, efficient manner.

Image-Based Localization (IBL) is the problem of estimating the 3D pose of a camera with respect to a 3D representation of the scene. IBL is quite challenging in large-scale environments spanning a wide variety of viewpoints, illumination, and areas where matching a query image against hundreds of thousands of 3D points becomes prone to a large number of outliers and ambiguous situations. The current state of the art IBL solutions attempted to address the problem using paradigms such as bag-of-words, features co-occurrence, deep learning and others, with varying degrees of success. This paper presents GIST-based Search Space Reduction (GSSR) for indoor and large scale Image-Based Localization applications such as relocalization, loop closure and location recognition. GSSR explores the use of global descriptors, in particular GIST, to introduce a new similarity measure for keyframes that combines the GIST descriptor scores of all neighboring frames to qualify a limited number of 3D points for the matching process, hence reducing the problem to its small size counterpart. Our results on standard datasets show that our system can achieve better localization accuracy and speed than the main state of the art. It obtains approximately 0.24m and 0.3◦ in less than 0.1 seconds. © 2016 British Machine Vision Association, BMVA. All rights reserved.

The secondary use of primary care data has many potential applications. By using data from a local primary care organization, a method for developing data quality measures and metrics in primary care is presented as a case study. The method that was created included an exploratory meeting with a subject matter expert, the creation of a first draft of measures with the information management team, the discussion of the proposed measures with a focus group and a final data quality report encompassing all the collected feedback. The method was used to create rules and formulae to measures timeliness, completeness, accuracy and usefulness in the primary care ecosystem. Future work will involve completing a detailed quantitative analysis of the data quality measures calculated with the proposed metrics. In the future these measures can be broken down and compared on a monthly, professional and users basis to provide insight into the behavior and nuance of data quality in primary care.

This paper presents a modeling methodology able to determine the analytical representations of conventional dielectrophoretic force, travelling-wave dielectrophoretic force and electroratation torque generated by quadrupole polynomial electrodes on a sphere microparticle. Firstly, theoretical analysis is performed to illustrate the linear-dependence of the electric potential distribution on the applied electrode voltages. Then finite element method and mathematical preprocessing are conducted to obtain the analytical expression of the electric potential. Consequently, the corresponding analytical representations for conventional dielectrophoretic force, travelling-wave dielectrophoretic force and electroratation torque with respect to the applied electrode voltages are obtained and the developed analytical models lead to a nonlinear nonaffine micromanipulation system. Numerical simulations are conducted by finite element method solver to demonstrate the effectiveness of the proposed modeling method. Finally, A dynamic feedback control is proposed for stable motion control of a microparticle in such a *** results illustrate the performance of the proposed control.
