1BioTRIZ Suggests Radiative Cooling of Buildings Can Be Done Passively by Changing the Structure of Roof Insulation to Let Longwave Infrared Pass显示文摘This paper demonstrates the application of a design tool called BioTRIZ. Its developers claim that it can be used to access biological strategies for solving engineering problems. Our aim is to design a roof for hot climates that gets free cooling through radiant coupling with the sky. The insulation in a standard roof stops the sun and convection from warming the thermal mass.But it also restricts the mass’s longwave view of the cool sky. Different solutions to this conflict are offered by BioTRIZ. The chosen solution is to replace the standard insulation component with an open cell honeycomb. The vertical cells would allow longwave radiation to pass, while arresting convection. The solutions offered by BioTRIZ’s technological counterpart includeno such changes in structure. It is estimated that the thermal mass in the biomimetic roof would remain on average 4.5?C cooler than in a standard roof over a year in Riyadh, Saudi Arabia.Salmaan Craig David Harrison Andrew Cripps Daniel Knott 2008Journal of Bionic Engineering2008,5,1:9
2Comparison of two remote sensing models for estimating evapotranspiration: algorithm evaluation and application in seasonally arid ecosystems in South Africa显示文摘Remote sensing tools are becoming increasingly important for providing spatial information on water use by different ecosystems. Despite significant advances in remote sensing based evapotranspiration(ET) models in recent years, important information gaps still exist on the accuracy of the models particularly in arid and semi-arid environments. In this study, we evaluated the Penman-Monteith based MOD16 and the modified Priestley-Taylor(PT-JPL) models at the daily time step against three measured ET datasets. We used data from two summer and one winter rainfall sites in South Africa. One site was dominated by native broad leaf and the other by fine leafed deciduous savanna tree species and C4 grasses. The third site was in the winter rainfall Cape region and had shrubby fynbos vegetation. Actual ET was measured using open-path eddy covariance systems at the summer rainfall sites while a surface energy balance system utilizing the large aperture boundary layer scintillometer was used in the Cape. Model performance varied between sites and between years with the worst estimates(R2<0.50 and RMSE>0.80 mm/d) observed during years with prolonged mid-summer dry spells in the summer rainfall areas. Sensitivity tests on MOD16 showed that the leaf area index, surface conductance and radiation budget parameters had the largest effect on simulated ET. MOD16 ET predictions were improved by:(1) reformulating the emissivity expressions in the net radiation equation;(2) incorporating representative surface conductance values;and(3) including a soil moisture stress function in the transpiration sub-model. Implementing these changes increased the accuracy of MOD16 daily ET predictions at all sites. However, similar adjustments to the PT-JPL model yielded minimal improvements. We conclude that the MOD16 ET model has the potential to accurately predict water use in arid environments provided soil water stress and accurate biome-specific parameters are incorporated.Sebinasi DZIKITI Nebo Z JOVANOVIC Richard DH BUGAN Abel RAMOELO Nobuhle P MAJOZI Alecia NICKLESS Moses A CHO David C LE MAITRE Zanele NTSHIDI Harrison H PIENAAR 2019Journal of Arid Land2019,11,4:4
3Flexible Strip Supercapacitors for Future Energy Storage显示文摘Flexible strip supercapacitors are developed and their electrochemical properties are characterized. Activated carbon is used as the electrode material and it is found to have a good porous structure which provides a large surface area for energy storage.Furthermore, this activated carbon performs well. The manufacturing processes for the supercapacitors are described in detail and the preparation process has good reproducibility. The strip supercapacitors are combined in series and parallel to measure their electrical properties. The performances of these two samples in series or in parallel both follow the theoretical models. The electrochemical potential window of a series circuit of these two strip supercapacitors is 4.8 V. The energy and power of the series or parallel circuits are equal to the sums of the two strip supercapacitors.Rui-Rong Zhang Yan-Meng Xu David Harrison John Fyson Fu-Lian Qiu Darren Southee 2015International Journal of Automation and computing2015,12,1:3

9Acute ischaemic stroke interventions: large vessel occlusion and beyond显示文摘Care for acute ischaemic stroke is one of the most rapidly evolving fields due to the robust outcomes achieved by mechanical thrombectomy.Large vessel occlusion(LVO)accounts for up to 38%of acute ischaemic stroke and comes with devastating outcomes for patients,families and society in the pre-intervention era.A paradigm shift and a breakthrough brought mechanical thrombectomy back into the spotlight for acute ischaemic stroke;this was because five randomised controlled trials from several countries concluded that mechanical thrombectomy for acute stroke offered overwhelming benefits.This review article will present a comprehensive overview of LVO management,techniques and devices used,and the future of stroke therapy.In addition,we review our institution experience of mechanical thrombectomy for posterior and distal circulation occlusion.Ahmad Sweid Batoul Hammoud Sunidhi Ramesh Daniella Wong Tyler D Alexander Joshua Harrison Weinberg Maureen Deprince Jaime Dougherty Dimitri Jean-Mickael Maamari Stavropoula Tjoumakaris Hekmat Zarzour Michael R Gooch Nabeel Herial Victor Romo David M Hasan Robert H Rosenwasser Pascal Jabbour 2020Stroke & Vascular Neurology2020,5,1:2
