A Large-Scale Educational Campaigns

Educational technology requires a delivery mechanism in order to scale. One method which has not yet seen widespread use is the educational campaign: large-scale, short-term events focused on a specific educational topic, such as the Hour of Code campaign. These are designed to generate media coverage and lend themselves nicely to collaborative or competitive goals, thus potentially leveraging ...

Large-Scale Election Campaigns: Combinatorial Shift Bribery

We study the complexity of a combinatorial variant of the Shift Bribery problem in elections. In the standard Shift Bribery problem, we are given an election where each voter has a preference order over the set of candidates and where an outside agent, the briber, can pay each voter to rank the briber’s favorite candidate a given number of positions higher. The goal is to ensure the victory of ...

Analyzing Large-Scale Public Campaigns on Twitter

Social media has become an important instrument for running various types of public campaigns and mobilizing people. Yet, the dynamics of public campaigns on social networking platforms still remain largely unexplored. In this paper, we present an in-depth analysis of over one hundred large-scale campaigns on social media platforms covering more than 6 years. In particular, we focus on campaign...

Full-Scale Bridge Finite-Element Model Calibration Using Measured Frequency-Response Functions

A frequency-response function–based parameter-estimation method was used for finite-element (FE) model calibration of a fullscale bridge using measured dynamic test data. Dynamic tests were performed on the bridge to obtain measured frequency-response functions. Data quality was ensured by comparing measured data with the FE model and removing erroneous data. A coherence data selector was devel...
