| 1 | Machine learning and price-based load scheduling for an optimal IoT control in the smart and frugal home显示文摘We pose and study a scheduling problem for an electric load to develop an Internet of Things(IoT)control system for power appliances,which takes advantage of real-time dynamic energy pricing.Using historical pricing data from a large U.S.power supplier,we study and compare several dynamic scheduling policies,which can be implemented in a smart home to activate a major appliance(dishwasher,washing machine,clothes dryer)at an optimal time of the day,to minimize electricity costs.We formulate our scheduling task as a supervised machine learning classification problem which activates the load during one of two preferred time bins.The features used in the machine learning problem are hourly market,spot and day-ahead prices along with delayed label of the prior day.We find that boosting tree-based algorithms outperform any other classification approach with measurable reduction of energy costs over certain types of naive and static policies.We observe that the delayed label has most predictive power across features,followed,on average,by spot,hourly market,and day-ahead energy prices.We further discuss implementation issues using a micro controller system coupled with cloud-based serverless computing and dynamic data storage.Our test system includes an interactive voice interface via an intelligent personal assistant. | Rachneet Kaur Clara Schaye Kevin Thompson Daniel C.Yee Rachel Zilz R.S.Sreenivas Richard B.Sowers | 2021 | Energy and AI2021，3，1： | 0 |

| 3 | Comparative Study of Three High Order Schemes for LES of Temporally Evolving Mixing Layers显示文摘Three high order shock-capturing schemes are compared for large eddy simulations(LES)of temporally evolving mixing layers for different convective Mach numbers ranging from the quasi-incompressible regime to highly compressible supersonic regime.The considered high order schemes are fifth-order WENO(WENO5),seventh-order WENO(WENO7)and the associated eighth-order central spatial base scheme with the dissipative portion of WENO7 as a nonlinear post-processing filter step(WENO7fi).This high order nonlinear filter method of Yee&Sjogreen is designed for accurate and efficient simulations of shock-free compressible turbulence,turbulence with shocklets and turbulence with strong shocks with minimum tuning of scheme parameters.The LES results by WENO7fi using the same scheme parameter agree well with experimental results compiled by Barone et al.,and published direct numerical simulations(DNS)work of Rogers&Moser and Pantano&Sarkar,whereas results by WENO5 andWENO7 compare poorly with experimental data and DNS computations. | Helen C.Yee Bjorn Sjögreen Abdellah Hadjadj | 2012 | Communications in Computational Physics2012，12，10： | 0 |
| 4 | An Earth-mass planet in a time of COVID-19:KMT-2020-BLG-0414Lb显示文摘We report the discovery of KMT-2020-BLG-0414 Lb,with a planet-to-host mass ratio q2=0.9-1.2×10-5=3-4 q⊕at 1σ,which is the lowest mass-ratio microlensing planet to date.Together with two other recent discoveries(4?q/q⊕?6),it fills out the previous empty sector at the bottom of the triangular(log s,log q)diagram,where s is the planet-host separation in units of the angular Einstein radiusθE.Hence,these discoveries call into question the existence,or at least the strength,of the break in the mass-ratio function that was previously suggested to account for the paucity of very low-q planets.Due to the extreme magnification of the event,Amax~1450 for the underlying single-lens event,its light curve revealed a second companion with q3~0.05 and|log s3|~1,i.e.,a factor~10 closer to or farther from the host in projection.The measurements of the microlens parallaxπE and the angular Einstein radiusθE allow estimates of the host,planet and second companion masses,(M1,M2,M3)~(0.3 M⊙,1.0 M⊕,17 MJ),the planet and second companion projected separations,(a⊥,2,a⊥,3)~(1.5,0.15 or 15)au,and system distance DL~1 kpc.The lens could account for most or all of the blended light(I~19.3)and so can be studied immediately with high-resolution photometric and spectroscopic observations that can further clarify the nature of the system.The planet was found as part of a new program of high-cadence follow-up observations of high-magnification events.The detection of this planet,despite the considerable difficulties imposed by COVID-19(two KMT sites and OGLE were shut down),illustrates the potential utility of this program. | Weicheng Zang Cheongho Han Iona Kondo Jennifer C.Yee Chung-Uk Lee Andrew Gould Shude Mao Leandro de Almeida Yossi Shvartzvald Xiangyu Zhang Michael D.Albrow Sun-Ju Chung Kyu-Ha Hwang Youn Kil Jung Yoon-Hyun Ryu In-Gu Shin Sang-Mok Cha Dong-Jin Kim Hyoun-Woo Kim Seung-Lee Kim Dong-Joo Lee Yongseok Lee Byeong-Gon Park Richard W.Pogge John Drummond Thiam-Guan Tan JoséDias do Nascimento Júnior Dan Maoz Matthew T.Penny Wei Zhu Ian A.Bond Fumio Abe Richard Barry David P.Bennett Aparna Bhattacharya Martin Donachie Hirosane Fujii Akihiko Fukui Yuki Hirao Yoshitaka Itow Rintaro Kirikawa Naoki Koshimoto Man Cheung Alex Li Yutaka Matsubara Yasushi Muraki Shota Miyazaki Greg Olmschenk Clément Ranc Nicholas J.Rattenbury Yuki Satoh Hikaru Shoji Stela Ishitani Silva Takahiro Sumi Daisuke Suzuki Yuzuru Tanaka Paul J.Tristram Tsubasa Yamawaki Atsunori Yonehara Andreea Petric Todd Burdullis Pascal Fouqué | 2021 | Research in Astronomy and Astrophysics2021，21，9： | 0 |
