The role of the aerodynamic modifications of the shapes of tall buildings

Lee, Jooeun, S.M. Massachusetts Institute of TechnologyMassachusetts Institute of Technology2011

With the advances in technology, recent tall building design has undergone a shift to the free-style geometric forms in the exuberant and liberal atmosphere. As a height of the building increases, it is more susceptible to vibration caused by wind because of its asymmetric distribution of mass and …

Effects of a tuned mass damper on wind-induced motions in tall buildings

Carlot, Julien (Julien Alexandre Laurent)Massachusetts Institute of Technology2012

… engineers have found solutions to build taller and taller structures. However, the race for the sky has not only brought up new ways of building, it has also created new problems to face, namely wind-induced motions. In particular, wind loadings are now the source of vibrations in …

A Localization Solution for an Autonomous Vehicle in an Urban Environment

Webster, Jonathan MichaelVirginia Tech2007

… estimation. The urban setting is marked by tall structures, overpasses, and tunnels. Each of these can corrupt GPS satellite signals, or completely obscure them, making it impossible to rely on GPS alone. Dead reckoning is still a useful tool in this environment, but as is always the case, …

Advancing Tendon-Driven Robotic Systems: From Climbing Robots to String Actuators

Poon, Ryan Joseph MarMassachusetts Institute of Technology2025

… solutions for environments where climbing tall structures is critical. Stemming from this climbing robot work is a novel actuator system combining a twisted string actuator (TSA) with a winch mechanism. Relative to traditional hydraulic and pneumatic systems, TSAs are compact but face …

Integrity and attack-resilience of GPS-based positioning and timing: a Bayesian and measurement fusion approach

Chauhan, Shubhendra Vikram SinghUniversity of Illinois at Urbana-Champaign2021

… applications related to these crucial infrastructures. GPS provides sub-microsecond accurate timing and meter level of accurate positioning. It has global coverage and is free for all users. The GPS positioning and timing service has some limitations. The positioning accuracy degrades in …
