Background: The COVID-19 pandemic highlighted gaps in health surveillance systems, disease prevention, and treatment globally. Among the many factors that might have led to these gaps is the issue of the financing of national health systems, especially in low-income and middle-income countries (LMICs), as well as a robust global system for pandemic preparedness. We aimed to provide a comparative assessment of global health spending at the onset of the pandemic;characterise the amount of development assistance for pandemic preparedness and response disbursed in the first 2 years of the COVID-19 pandemic;and examine expectations for future health spending and put into context the expected need for investment in pandemic preparedness. Methods: In this analysis of global health spending between 1990 and 2021, and prediction from 2021 to 2026, we estimated four sources of health spending: development assistance for health (DAH), government spending, out-of-pocket spending, and prepaid private spending across 204 countries and territories. We used the Organisation for Economic Co-operation and Development (OECD)'s Creditor Reporting System (CRS) and the WHO Global Health Expenditure Database (GHED) to estimate spending. We estimated development assistance for general health, COVID-19 response, and pandemic preparedness and response using a keyword search. Health spending estimates were combined with estimates of resources needed for pandemic prevention and preparedness to analyse future health spending patterns, relative to need. Findings: In 2019, at the onset of the COVID-19 pandemic, US$9·2 trillion (95% uncertainty interval [UI] 9·1–9·3) was spent on health worldwide. We found great disparities in the amount of resources devoted to health, with high-income countries spending $7·3 trillion (95% UI 7·2–7·4) in 2019;293·7 times the $24·8 billion (95% UI 24·3–25·3) spent by low-income countries in 2019. That same year, $43·1 billion in development assistance was provided

Surveillance video is characterized by large amount of data and redundancy, which makes the suspicious face detection to be a problem. To solve the problem above we proposed suspicious face detection based on key frame. Surveillance video has the type of fixed background, so this paper used the frame difference method with low computational complexity and small computation to extract the key frame. We proposed a new method combined DPM with skin color detection to detect the suspicious face in the key frames. To solve the speed bottleneck of the traditional DPM, we proposed to use the fast HOG LUT feature extraction and the near optimal cost sensitive decision making improving the traditional method. Meanwhile we used YCrCb + otsu skin color segmentation. Since the otsu is easily affected by the illumination, we proposed an improved skin color detection. Experiment results show that the proposed algorithms are robust and accurate for real-time. © Springer International Publishing Switzerland 2016.

CIM is widely adopted by many power utilities since it offers interoperability through standard information models. This paper discusses the CIM based modeling aspects for representing a regional power system network of Indian power grid in CIM format. Two control center applications, namely network model exchange and state estimation are considered. The CIM based modeling approach addresses three significant problems faced by utilities such as 1) seamless exchange of network models, 2) representation of boundary elements which are typically modeled in the networks of both the neighboring control areas, and 3) exchange of state variables obtained from state estimation application. The model authority sets (MAS) are defined for handling of boundary elements that occur at the regional network boundaries, wherein the globally unique reference IDs are allotted for unique identification of power system resources. The MAS approach supports easy merging of multiple regional CIM network models into a national CIM network model. The CIM profiles for network model exchange and state estimation applications are defined. Consequently, CIM/RDF/XML message payloads for the applications are generated for western region 400 kV network of Indian power grid.

The field of practical character recognition has seen great advances these years, owing the to proposition of effective newmethod and progress in computer hardware. However, lots of problems like precision and progressing speed remain to be solved. This paper proposes a useful practical optical character recognition method of both Chinese character and English character. Given a photo randomly taken, we pre-progress it to undo the influence of light and tilt. Then we separate each word to extract 8-direction chain-code feature of it. When faced with complex scene, the method we propose achieve relatively high precision and fast speed. © 2015 Taylor & Francis Group.

Background: In an era of shifting global agendas and expanded emphasis on non-communicable diseases and injuries along with communicable diseases, sound evidence on trends by cause at the national level is essential. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) provides a systematic scientific assessment of published, publicly available, and contributed data on incidence, prevalence, and mortality for a mutually exclusive and collectively exhaustive list of diseases and injuries. Methods: GBD estimates incidence, prevalence, mortality, years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life-years (DALYs) due to 369 diseases and injuries, for two sexes, and for 204 countries and territories. Input data were extracted from censuses, household surveys, civil registration and vital statistics, disease registries, health service use, air pollution monitors, satellite imaging, disease notifications, and other sources. Cause-specific death rates and cause fractions were calculated using the Cause of Death Ensemble model and spatiotemporal Gaussian process regression. Cause-specific deaths were adjusted to match the total all-cause deaths calculated as part of the GBD population, fertility, and mortality estimates. Deaths were multiplied by standard life expectancy at each age to calculate YLLs. A Bayesian meta-regression modelling tool, DisMod-MR 2.1, was used to ensure consistency between incidence, prevalence, remission, excess mortality, and cause-specific mortality for most causes. Prevalence estimates were multiplied by disability weights for mutually exclusive sequelae of diseases and injuries to calculate YLDs. We considered results in the context of the Socio-demographic Index (SDI), a composite indicator of income per capita, years of schooling, and fertility rate in females younger than 25 years. Uncertainty intervals (UIs) were generated for every metric using the 25th and 975th ordered 1000 draw value

Ensuring the security of a wide variety of applications such as public security, access control and banking, is becoming an increasingly important problem as modern technology is integrated into the majority of these applications. Thus, establishing identity of a person is the significant method used to ensure a high security level. As a security method, biometric identification has a long tradition and is a synonym for the uniqueness of person. In this paper, based on Finger-Knuckle-Print (FKP), we present a multimodal personal identification system using two feature extraction methods with their fusion applied at the matching score level. In this study, the segmented FKP is firstly represented by the Histogram of Oriented Gradients(HOG) descriptors. Subsequently, the Radial Basis Function(RBF) and Random Forest Transform (RFT) models are used to design two sub-systems. The proposed method is validated for their efficacy on the available PolyU FKP Database of 165 users. Our experimental results show the effectiveness and reliability of the proposed approach, which brings both high identification and accuracy rate.

Code-reuse attacks have become the primary exploitation technique for system compromise despite of the recently introduced Data Execution Prevention technique in modern platforms. Different from code injection attacks, they result in unintended control-flow transfer to victim programs without adding malicious code. This paper proposes a practical scheme named as CFI Guard to detect code-reuse attacks on user space applications. CFI Guard traces every branch execution by leveraging hardware features of commodity processors, and then validates the traces based on fine-grained control flow graphs. We have implemented a prototype of CFI Guard on Linux and the experiments show that it only incurs around 2.9% runtime overhead for a set of typical server applications. © Springer International Publishing Switzerland 2015.

The requirement for higher Security and Dependability (S&D) of systems is continuously increasing, even in domains traditionally not deeply involved in such issues. Nowadays, many practitioners express their worries about current S&D software engineering practices. New recommendations should be considered to ground this discipline on two pillars: solid theory and proven principles. We took the second pillar towards software engineering for embedded system applications, focusing on the problem of integrating S&D by design to foster reuse. In this paper, we propose to combine design patterns and Model Driven engineering (MDE) techniques for building component-based applications with safety requirements. The resulting modeling framework serves primarily to capture the basic concepts for specifying safety-oriented design patterns, building an S&D pattern system, and maintain safety properties, with existing modeling artifacts, during the engineering process based on the S&D pattern system. As a proof of concept, we are evaluating the feasibility of the framework through the example of the MooN pattern system for building systems having safety requirements: Communication Based Train Control (CBTC). © 2015 Copyright held by the owner/author(s).
