Semantic Activity Classification Using Locomotive Signatures from Mobile Phones

Karl Aberer, Zhixian Yan, Dipanjan Chakraborty, Ho Young Jeung

We explore the use of mobile phone-generated sensor feeds to determine the high-level (i.e., at the semantic level), indoor, lifestyle activities of individuals, such as cooking & dining at home and working & having lunch at the work- place. We propose and ...

Polar Codes: Robustness of the Successive Cancellation Decoder with Respect to Quantization

Rüdiger Urbanke, Seyed Hamed Hassani

Polar codes provably achieve the capacity of a wide array of channels under successive decoding. This assumes infinite precision arithmetic. Given the successive nature of the decoding algorithm, one might worry about the sensitivity of the performance to ...

The timing of exploratory decision-making revealed by single-trial topographic EEG analyses

José del Rocio Millán Ruiz, Ricardo Andres Chavarriaga Lozano, Nicolas Bourdaud, Micah Murray, Athina Tzovara

Decision-making in an uncertain environment is driven by two major needs: exploring the environment to gather information or exploiting acquired knowledge to maximize reward. The neural processes underlying exploratory decision-making have been mainly stud ...

Quantitative Determination of the Band Gap of WS2 with Ambipolar Ionic Liquid-Gated Transistors

Helmuth Berger

We realized ambipolar field-effect transistors by coupling exfoliated thin flakes of tungsten disulfide (WS2) with an ionic liquid dielectric. The devices show ideal electrical characteristics, including very steep subthreshold slopes for both electrons an ...

Query Optimization in Context of Pseudo Relevant Documents

Ashish Kishore Bindal

In conventional vector space model for information retrieval, query vector generation is imperfect for retrieval of precise documents which are de-sired by user. In this paper, we present a stochastic based approach for optimiz-ing query vector without use ...

RANSAC-based Enhancement in Drug Concentration Prediction Using Support Vector Machine

Giovanni De Micheli, Alena Simalatsar, Wenqi You Dubout

Training Support Vector Machines (SVMs) to predict drugs concentrations is often difficult because of the high level of noise in the training data, due to various kinds of measurement errors. We apply RANdom SAmple Consensus (RANSAC) algorithm in this pape ...

Spatially resolved skin friction velocity measurements using Irwin sensors: A calibration and accuracy analysis

Michael Lehning, Katherine Colby Leonard, Benjamin Andreas Walter

This study investigates the accuracy of spatially resolved skin friction velocity uτ measurements using a large number of Irwin sensors (Irwin, 1981). A fast and simple procedure to calibrate the sensors against a two-component hot-film anemometer is intro ...

State Estimation of Active Distribution Networks: Comparison Between WLS and Iterated Kalman-Filter Algorithm Integrating PMUs

Mario Paolone, Carlo Alberto Nucci, Styliani Sarri

One of the challenging tasks related to the realtime control of Active Distribution Networks (ADNs) is represented by the development of fast (i.e. sub-second) state estimation (SE) processes. As known, the problem of SE of power networks links the measure ...

A novel high-throughput on-wafer electromechanical sensitivity characterization system for piezoresistive cantilevers

Luis Guillermo Villanueva Torrijo

In this work we present the development of a new set-up that allows on-wafer sensitivity characterization of piezoresistive cantilevers. In this way we reduce considerably the testing time compared to the techniques available up to date but at the same tim ...
