8Performance and safety of transport vehicles fueled with alternative fuels in plateau environment:A review显示文摘Alternative fuels including natural gas,alcohols and biodiesel for transport vehicles have been applied worldwidely.However,the performance and safety of alternative fuel vehicles have changed when the application environment varies from plain condition to the plateau,resulting from the variation of air density and atmospheric pressure.Natural gasfueled vehicles exhibited lower output and greater fuel consumption than gasoline-fueled vehicles in plateau environment.The oxygenated additives including alcohols and biodiesel can supply extra oxygen into the cylinder,which may benefit the engine performances compared with traditional petroleum in plateau environments.However,compared with plain environment,vehicles fueled with oxygenated fuels worsen the engine thermal efficiency,the power performance and the fuel economy in the plateau.With the increase of altitude,HC and CO emissions increase;whereas NO_(x)emissions show no evident change at various altitudes.Intake boosting,spark or injection timing optimization,and intake manifold optimization can effectively improve the combustion and performance of vehicles in the plateau.Safety is another significant factor for application of alternative fuels.Compared with plain environment,safeties of vehicles fueled with natural gas or biodiesel in the plateau have not been reduced,whereas safety of methanol and ethanol vehicles decrease,because they are easier to form air fuel mixture,have lower flash points,and have higher possibilities of gas resistance.The study proves that the performance and safety and alternative fuel vehicles deteriorate when the application locale varies from the plain region to the plateau region.Wanjiang Guo Hui Wang Hao Chen Binyan Yu Ying Wang Jianyou Zhao 2022Journal of Traffic and Transportation Engineering(English Edition)2022,9,6:0
9Effects of personalized exercise prescriptions and social media delivered through mobile health on cancer survivors’physical activity and quality of life显示文摘Purpose This study aimed to examine the effects of a multi-component mobile health intervention(wearable,apps,and social media)on cancer survivors’(CS')physical activity(PA),quality of life,and PA determinants compared to exercise prescription only,social media only,and attention control conditions.Methods A total of 126 CS(age=60.37±7.41 years,mean±SD)were recruited from the United States.The study duration was 6 months and participants were randomly placed into 4 groups.All participants received a Fitbit tracker and were instructed to install its companion app to monitor their daily PA.They(1)received previously established weekly personalized exercise prescriptions via email,(2)received weekly Facebook health education and interacted with one another,(3)received both Conditions 1 and 2,or(4)were part of the control condition,meaning they adopted usual care.CS PA daily steps,quality of life(i.e.,physical health and mental health),and PA determinants(e.g.,self-efficacy,social support)were measured at baseline,3 months,and 6 months.Results The final sample size included 123 CS.The results revealed only the multi-component condition had greater improvements in PA daily steps than the control condition post-intervention(95%confidence interval(95%CI):368–2951;p<0.05).Similarly,those in the multi-component condition had significantly greater increased physical health than the control condition(95%CI:–0.41 to–0.01;p<0.05)over time.In addition,the social media condition had significantly greater increased perceived social support than the control condition(95%CI:0.01–0.93;p<0.05).No other significant differences on outcomes were identified.Conclusion The study findings suggest that the implementation of a multi-component mobile health intervention had positive effects on CS PA steps and physical health.Also,offering social media intervention has the potential to improve CS perceived social support.Zan Gao Suryeon Ryu Wanjiang Zhou Kaitlyn Adams Mohamed Hassan Rui Zhang Anne Blaes Julian Wolfson Ju Sun 2023Journal of Sport and Health Science2023,12,6:0

12Online Learning-Based Offloading Decision and Resource Allocation in Mobile Edge Computing-Enabled Satellite-Terrestrial Networks显示文摘Mobile edge computing(MEC)-enabled satellite-terrestrial networks(STNs)can provide Internet of Things(IoT)devices with global computing services.Sometimes,the network state information is uncertain or unknown.To deal with this situation,we investigate online learning-based offloading decision and resource allocation in MEC-enabled STNs in this paper.The problem of minimizing the average sum task completion delay of all IoT devices over all time periods is formulated.We decompose this optimization problem into a task offloading decision problem and a computing resource allocation problem.A joint optimization scheme of offloading decision and resource allocation is then proposed,which consists of a task offloading decision algorithm based on the devices cooperation aided upper confidence bound(UCB)algorithm and a computing resource allocation algorithm based on the Lagrange multiplier method.Simulation results validate that the proposed scheme performs better than other baseline schemes.Tong Minglei Li Song Han Wanjiang Wang Xiaoxiang 2024China Communications2024,21,3:0

15An Automated Penetration Semantic Knowledge Mining Algorithm Based on Bayesian Inference显示文摘Mining penetration testing semantic knowledge hidden in vast amounts of raw penetration testing data is of vital importance for automated penetration testing.Associative rule mining,a data mining technique,has been studied and explored for a long time.However,few studies have focused on knowledge discovery in the penetration testing area.The experimental result reveals that the long-tail distribution of penetration testing data nullifies the effectiveness of associative rule mining algorithms that are based on frequent pattern.To address this problem,a Bayesian inference based penetration semantic knowledge mining algorithm is proposed.First,a directed bipartite graph model,a kind of Bayesian network,is constructed to formalize penetration testing data.Then,we adopt the maximum likelihood estimate method to optimize the model parameters and decompose a large Bayesian network into smaller networks based on conditional independence of variables for improved solution efficiency.Finally,irrelevant variable elimination is adopted to extract penetration semantic knowledge from the conditional probability distribution of the model.The experimental results show that the proposed method can discover penetration semantic knowledge from raw penetration testing data effectively and efficiently.Yichao Zang Tairan Hu Tianyang Zhou Wanjiang Deng 2021Computers, Materials & Continua2021,,3:0

18Framework on low-carbon retrofit of rural residential buildings in arid areas of northwest China:A case study of Turpan residential buildings显示文摘At present,buildings in arid and hot regions are facing severe challenges of indoor comfort improvement and carbon emission reduction,especially in rural areas.Multi-objective optimization could be an effective tool for tackling the aforementioned challenges.Therefore,this paper proposes a life-cycle optimization framework considering thermal comfort,which is beneficial to promoting residents’motivation for low-carbon retrofit in arid climate regions.First,in response to the above problems,three objective functions are specified in the framework,which are global warming potential(GWP),life cycle cost(LCC),and thermal discomfort hours(TDH).To improve the optimization efficiency,this research uses Deep Neural Networks(DNN)combined with NSGA-II to construct a high-precision prediction model(meta-model for optimization)based on the energy consumption simulation database formed by the orthogonal multi-dimensional design parameters.The accuracy index of the modified model is R2>0.99,cv(RMSE)≤1%,and NMBE≤0.2%,which gets rid of the dilemma of low prediction accuracy of traditional machine learning models.In the scheme comparison and selection stage,the TOPSIS based on two empowerment methods is applied to meet different design tendencies,where the entropy-based method can avoid the interference of subjective preference and significantly improve the objectivity and scientific nature of decision analysis.Additionally,sensitivity analysis is conducted on the variables,which supports guidance for practitioners to carry out the low-carbon design.Finally,the multi-objective optimization analysis for a farmhouse in Turpan is taken as a case study to evaluate the performance of the framework.The results show that the framework could significantly improve the building performance,with 60.8%,52.5%,and 14.2%reduction in GWP,LCC,and TDH,respectively.Junkang Song Wanjiang Wang Pingan Ni Hanjie Zheng Zihan Zhang Yihuan Zhou 2023Building Simulation2023,16,2:0
