DRIVE: One-bit Distributed Mean Estimation [article]

Shay Vargaftik, Ran Ben Basat, Amit Portnoy, Gal Mendelson, Yaniv Ben-Itzhak, Michael Mitzenmacher
2021 arXiv   pre-print
We consider the problem where n clients transmit d-dimensional real-valued vectors using d(1+o(1)) bits each, in a manner that allows the receiver to approximately reconstruct their mean.  ...  We evaluate our methods on a collection of distributed and federated learning tasks, using a variety of datasets, and show a consistent improvement over the state of the art.  ...  MM and RBB were supported in part by a gift to the Center for Research on Computation and Society at Harvard University.  ...

DRIVING

Xi Chen, Lei Rao, Qiao Xiang, Xue Liu, Fan Bai
2016 Proceedings of the 2016 ACM on Multimedia Conference - MM '16  
To fill the gap, we propose the Delay-awaRe dIstributed Video schedulING (DRIVING) framework.  ...  As a result, the new in-cabin Wi-Fi systems have been deployed, enabling each vehicle as a streaming hotspot on the wheels.  ...  Given the stationary distribution, D k is estimated as D k = σ · ∞ t=0 t · e k (t). (27) The Average Queueing Delay of λ k > μ k We focus on the DTMC shown in Fig. 5 .  ...

DTC-FPGA Drive for Induction Motors [chapter]

Rafael Rodríguez-Ponce, Fortino Mendoza-Mondragón, Moisés Martínez-Hernández, Marcelino Gutiérrez-Villalobos
2015 Induction Motors - Applications, Control and Fault Diagnostics  
With this new architecture, the authors hope to provide guidelines and insights for future research on DTC drives for induction motors.  ...  However, this technique is often accompanied by an unwanted deformation on the torque and flux signals denominated ripple, which can cause audible noise and vibration on the motor.  ...  Torque and flux estimator: the real time electromagnetic torque and magnetic flux vectors are estimated based on motor current and voltage signals.  ...

Trust Drives Internet Use

Martin Ljunge
2012 Social Science Research Network  
This paper estimates the effect of trust on internet use by studying the general population as well as second generation immigrants in 29 European countries with ancestry in 87 nations.  ...  The finding provides evidence for one mechanism through which trust creates good outcomes.  ...  The estimated effect of ancestral trust is also present on the father's side, but it is a bit less precisely estimated. The results are robust to controlling for mother's and father's education.  ...

Flash Drive Lifespan *is* a Problem

Tao Zhang, Aviad Zuck, Donald E. Porter, Dan Tsafrir
2017 Proceedings of the 16th Workshop on Hot Topics in Operating Systems - HotOS '17  
This result is concerning, as it means that installing malicious or poorly-written software could destroy the device itself.  ...  To our surprise, we find that, in a matter of days, simple, unprivileged applications can render the drive of several smartphones (and thus, the phone) inoperable.  ...  ACKNOWLEDGMENTS We thank the anonymous reviewers for their insightful comments on earlier drafts of the work.  ...

A Representative Driving Cycle for the Southern Expressway Compared to Existing Driving Cycles

Uditha Galgamuwa, Loshaka Perera, Saman Bandara
2016 Transportation in Developing Economies  
An on-road speed/time data sample was collected, and a driving cycle was developed to compare to well-established driving cycles worldwide.  ...  Data was collected in proportion to the number of actual trips made by users on an average day using the on-board method; the segment-based method was adopted for cycle construction.  ...  PKE was lowest among considered driving cycles, but RMS value was bit higher, leading to the conclusion that the driving behavior is smooth on the SEW.  ...
