Several recent research efforts in visualizing construction are rooted in scheduling. They involve linking activitybased construction schedules and 3D CAD models of facilities to describe discretely-evolving construction “product” visualizations called 4D CAD. The focus is on communicating what component(s) are built where and when. The construction processes or operations actually involved in ...

Fault-tolerant quantum computation with depolarization error often requires demanding threshold and resource overhead. If the operations can maintain high noise bias---dominated by dephasing small bit-flip error---we achieve hardware-efficient fault-tolerant a more favorable threshold. Distinct from two-level physical systems, multilevel systems (such as harmonic oscillators) desirable set of b...

Offshore platforms and windmills are constructed by assembling huge mechanical structures transported heavy lift vessels. The construction process comprises two interconnected operations, the dynamic positioning (DP) of vessel lifting loads. DP system is commonly designed tuned for case that there no load or free-hanging (mode 1). During transition from to connected a which mounted platform 2),...

We provide new constructions of several fundamental pseudorandom objects. Loosely speaking, these constructions obtain exponential improvements in efficiency compared to previous constructions with comparable randomness complexity. Our measure of efficiency is the number of word operations, as captured by the well-established unitcost word RAM model. Our main results are the following: 1. A fam...

Effective and detailed planning of large-scale, complex construction projects is of great importance to fulfilling project cost and time objectives. At Tsinghua University of China and The Hong Kong Polytechnic University, the four dimensional-computer aided design (4D construction operations simulation methodology have been researched for years respectively, resulting in innovative, in constru...
