Furthermore, when the subjected geological formation is rocky and the use of explosives is required, the demands of successful blasting are multiplied. The present paper proposes a classification system, named： BQS （Blastability Quality System）, for rock masses with closely spaced discontinuities （spacing lower than 0.1 m）. It is obvious that rock quality is one of the main characteristics which define the blast ability of a rock. The BQS can be an easy and widely-used tool as it is a quick evaluator for blastability and rock mass quality at one time. Taking into consideration the research calculations and the parameters of BQS, what has been at question in this paper is the effect of blast ability in a geological formation with closely spaced discontinuities.展开更多

文摘Success in the excavation of geological formations is commonly known as being very important in asserting stability. Furthermore, when the subjected geological formation is rocky and the use of explosives is required, the demands of successful blasting are multiplied. The present paper proposes a classification system, named： BQS （Blastability Quality System）, for rock masses with closely spaced discontinuities （spacing lower than 0.1 m）. It is obvious that rock quality is one of the main characteristics which define the blast ability of a rock. The BQS can be an easy and widely-used tool as it is a quick evaluator for blastability and rock mass quality at one time. Taking into consideration the research calculations and the parameters of BQS, what has been at question in this paper is the effect of blast ability in a geological formation with closely spaced discontinuities.

文摘Power quality is a crucial area of research in contemporary power systems,particularly given the rapid proliferation of intermittent renewable energy sources such as wind power.This study investigated the relationships between power quality indices of system output and PSD by utilizing theories related to spectra,PSD,and random signal power spectra.The relationship was derived,validated through experiments and simulations,and subsequently applied to multi-objective optimization.Various optimization algorithms were compared to achieve optimal system power quality.The findings revealed that the relationships between power quality indices and PSD were influenced by variations in the order of the power spectral estimation model.An increase in the order of the AR model resulted in a 36%improvement in the number of optimal solutions.Regarding optimal solution distribution,NSGA-II demonstrated superior diversity,while MOEA/D exhibited better convergence.However,practical applications showed that while MOEA/D had higher convergence,NSGA-II produced superior optimal solutions,achieving the best power quality indices(THDi at 4.62%,d%at 3.51%,and cosφat 96%).These results suggest that the proposed method holds significant potential for optimizing power quality in practical applications.
文摘BACKGROUND The coronavirus disease 2019(COVID-19)pandemic has had profound physical,psychological,and social consequences,with lasting effects on health-related quality of life(HRQoL)among people with a history of COVID-19.AIM To synthesize the current evidence on HRQoL and long-term health outcomes among people with a history of COVID-19 in India.METHODS We incorporated studies from India reporting post-COVID HRQoL outcomes using validated instruments,including the 5-level EuroQol 5-Dimensional questionnaire,the EuroQol Visual Analogue Scale,the Short Form-36 Health Survey,the World Health Organization Quality of Life-Brief Version,and the European Health Interview Survey-Quality of Life.Pooled mean 5-level EuroQol 5-Dimensional questionnaire scores with 95%CIs were calculated for HRQoL.Adjusted odds ratios were pooled for comorbidity,disease severity,intensive care unit admission,age,sex,and vaccination status using random-effects models.RESULTS Three studies(n=1526)reported EuroQol instruments,with the 5-level EuroQol 5-Dimensional questionnaire utility scores suitable for quantitative pooling.The pooled mean utility was 0.83(95%CI:0.75-0.92),although heterogeneity was high because the included studies represented clinically distinct populations.Across all studies,several determinants were consistently associated with impaired HRQoL.Older adults(≥60 years)had higher odds of poor HRQoL[pooled odds ratio(OR)=1.83,95%CI:1.43-2.35],and females were more likely to experience impaired HRQoL(pooled OR=1.74,95%CI:1.44-2.10),whereas males had a lower risk(pooled OR=0.58,95%CI:0.48-0.70).Being unvaccinated increased the likelihood of persistent symptoms or reduced HRQoL(pooled OR=1.60,95%CI:1.21-2.14).Comorbidity(pooled OR=1.94,95%CI:1.43-2.63)and severe acute COVID-19 or intensive care unit admission(pooled OR=2.77,95%CI:2.13-3.59)were also strongly associated with poorer HRQoL Six additional studies utilizing disparate instruments(EuroQol Visual Analogue Scale,Short Form-36 Health Survey,World Health Organization Quality of Life-Brief Version,European Health Interview Survey-Quality of Life)were excluded from quantitative synthesis due to measurement heterogeneity.CONCLUSION Post-COVID HRQoL in people with a history of COVID-19 in India is suboptimal,with greater impairment observed among older adults,females,patients with comorbidities or severe disease,and unvaccinated individuals.These findings highlight the need for targeted rehabilitation and preventive strategies.
