The current work proposes a new approach for handling risks based on predictive analytics and machine learning (ML) that can work in real-time to help avoid risks and increase project adaptability. The main research aim of the study is to ascertain risk presence in projects by using historical data from previous projects, focusing on important aspects such as time, task time, resources and project results. t-SNE technique applies feature engineering in the reduction of the dimensionality while preserving important structural properties.

文摘The urgent necessity for enhanced risk stratification to improve the efficiency of colonoscopy screening is underscored by the fact that colorectal cancer(CRC)continues to be a primary cause of global cancer mortality.Conventional models mostly rely on generalized obesity markers including body mass index(BMI),which does not effectively represent oncogenic risk linked with abdominal obesity.Liu et al undertook a large-scale case-control study comprising 6484 firsttime colonoscopy patients at a prominent Chinese hospital between 2020 and 2023 to overcome this restriction.Age,male sex,smoking status,and raised waist-hip ratio(WHR)were found by multivariate logistic regression as independent predictors of advanced colorectal neoplasia(ACN).In a validation cohort of 1891 individuals,a new 7-point risk scoring model was created and stratified into low-(5.0%)ACN prevalence,moderate-(10.3%)and high-risk(17.6%).With C-statistic=0.66 the model showed better discriminating ability than the Asia-Pacific Colorectal Screening(APCS)score(C-statistic=0.63)and the BMI-modified APCS model.These results fit newly published data showing central obesity as a major carcinogenic driver via pro-inflammatory visceral adipokine channels.With the use of WHR,patient risk classification is greatly improved,providing a practical tool to make the most of screening resources in the face of rising CRC incidence rates.Finally,multi-ethnic validation is necessary for the WHR-based scoring model to be considered for integration into global CRC preventive frameworks,since it improves the accuracy of ACN risk prediction.
文摘Prophylactic fixation(ProFix)of the proximal femur in elderly patients with osteoporosis presents a forward-thinking approach to preventing debilitating fractures and their associated complications.By addressing fracture risk before an injury occurs,ProFix has the potential to enhance patient outcomes,promote long-term mobility,and reduce healthcare costs.Early intervention in individuals at high risk can significantly lower hospital admissions,shorten recovery periods,and preserve independence,mitigating challenges such as chronic pain and reduced life expectancy.Given the high prevalence of undiagnosed osteoporosis,prioritising early risk assessment and targeted prevention is essential.Advancements in minimally invasive surgical techniques and safer anaesthesia methods further support ProFix as a feasible and effective strategy to decrease fracturerelated morbidity,improve overall patient well-being,and optimise the use of healthcare resources.This opinion review details the evidence supporting this concept,its efficacy,the challenges in its implementation,and a strategic plan for future implementation.
文摘Electric vehicle(EV)monitoring systems commonly depend on IoT-based sensormeasurements to track key performance parameters such as vehicle speed,state of charge(SoC),battery temperature,power consumption,motor RPM,and regenerative braking.While these systems enable real-time data acquisition,they are often hindered by sensor noise,communication delays,andmeasurement uncertainties,which compromise their reliability for critical decision-making.To overcome these limitations,this study introduces a comparative framework that integrates reference signals,a digital twin model emulating ideal system behavior,and real-time IoT measurements.The digital twin provides a predictive and noise-resilient representation of EV dynamics,enabling enhanced monitoring accuracy.Six critical parameters are evaluated using root mean square error(RMSE),mean absolute error(MAE),maximum deviation,and correlation coefficient(R^(2)).Results show that the digital twin significantly improves estimation fidelity,with RMSE for speed reduced from 2.5 km/h(IoT)to 1.2 km/h and R^(2) values generally exceeding 0.99,except for regenerative braking which achieved 0.982.These findings demonstrate the framework’s effectiveness in improving operational safety,energy management,and system reliability,offering a robust foundation for future advancements in adaptive calibration,predictive analytics,and fault detection in EV systems.

文摘With ever-increasing market competition and advances in technology, more and more countries are prioritizing advanced manufacturing technology as their top priority for economic growth. Germany announced the Industry 4.0 strategy in 2013. The US government launched the Advanced Manufacturing Partnership （AMP） in 2011 and the National Network for Manufacturing Innovation （NNMI） in 2014. Most recently, the Manufacturing USA initiative was officially rolled out to further ＂leverage existing resources... to nurture manufacturing innovation and accelerate commercialization＂ by fostering close collaboration between industry, academia, and government partners. In 2015, the Chinese government officially published a 10- year plan and roadmap toward manufacturing： Made in China 2025. In all these national initiatives, the core technology development and implementation is in the area of advanced manufacturing systems. A new manufacturing paradigm is emerging, which can be characterized by two unique features： integrated manufacturing and intelligent manufacturing. This trend is in line with the progress of industrial revolutions, in which higher efficiency in production systems is being continuously pursued. To this end, 10 major technologies can be identified for the new manufacturing paradigm. This paper describes the rationales and needs for integrated and intelligent manufacturing （i2M） systems. Related technologies from different fields are also described. In particular, key technological enablers, such as the Intemet of Things and Services （IoTS）, cyber-physical systems （CPSs）, and cloud computing are discussed. Challenges are addressed with applica- tions that are based on commercially available platforms such as General Electric （GE）＇s Predix and PTC＇s ThingWorx.
文摘The virus SARS-CoV2,which causes the Coronavirus disease COVID-19 has become a pandemic and has spread to every inhabited continent.Given the increasing caseload,there is an urgent need to augment clinical skills in order to identify from among the many mild cases the few that will progress to critical illness.We present a first step towards building an artificial intelligence(AI)framework,with predictive analytics(PA)capabilities applied to real patient data,to provide rapid clinical decision-making support.COVID-19 has presented a pressing need as a)clinicians are still developing clinical acumen given the disease’s novelty,and b)resource limitations in a rapidly expanding pandemic require difficult decisions relating to resource allocation.The objectives of this research are:(1)to algorithmically identify the combinations of clinical characteristics of COVID-19 that predict outcomes,and(2)to develop a tool with AI capabilities that will predict patients at risk for more severe illness on initial presentation.The predictive models learn from historical data to help predict specifically who will develop acute respiratory distress syndrome(ARDS),a severe outcome in COVID-19.Our experimental results based on two hospitals in Wenzhou,Zhejang,China identify features most predictive of ARDS in COVID-19 initial presentation which would not have stood out to clinicians.A mild increase in elevated alanine aminotransferase(ALT)(a liver enzyme)),a presence of myalgias(body aches),and an increase in hemoglobin,in this order,are the clinical features,on presentation,that are the most predictive.Those two centers’COVID-19 case series symptoms on initial presentation can help predict severe outcomes.Predictive models that learned from historical data of patients from two Chinese hospitals achieved 70%to 80%accuracy in predicting severe cases.
