Virtual Reality (VR) and Augmented Reality (AR) are exciting technologies that offer considerable potential benefits in all stages of the Architecture, Engineering and Construction (AEC) process, from initial planning and conceptual design to facility management and operations. VR and AR allow people to visualize and interact with a building or infrastructure design and construction process in ...

The extended power construction can be used to create new framed manifolds out of old. We show here how to compute the effect of such operations in the Adams spectral sequence, extending partial results of Milgram and the author. This gives the simplest method of proving that Jones’ 30manifold has Kervaire invariant one, and allows the construction of manifolds representing Mahowald’s classes η...

We are developing a plan construction and plan execution monitoring system to automate the operation of the communications link in NASA’s Deep Space Network (DSN). The objectives of this effort are: (1) to archive knowledge of operations procedures; (2) provide a capability to assist in execution monitoring; and (3) provide a capability for automatically constructing the plan to be executed and...

Graph complexity measures like tree-width, clique-width and rank-width are important because they yield Fixed Parameter Tractable algorithms. These algorithms are based on hierarchical decompositions of the considered graphs and on boundedness conditions on the graph operations that, more or less explicitly, recombine the components of decompositions into larger graphs. Rank-width is de ned in ...

In this technical appendix we provide proofs for the various results stated in the manuscript titled: “When promotions meet operations: Cross-selling and its effect on call-center performance”. We start the technical appendix with the construction of the sample paths for all related processes. Specifically, our construction follows a strong approximation approach (see for example [7] and [8]). ...

Integrating dedicated applications with a wireless LAN and WAN infrastructure, the COSMOS system provides "Construction Site Mobile Operations Support". In this paper, we focus on the approach taken in COSMOS for bandwidth management across the bottleneck satellite WAN link, particularly for supporting video conferencing between company headquarters and construction sites. We discuss the IETF Q...

In analogy with steerable wavelets, we present a general construction of adaptable tight wavelet frames, with an emphasis on scaling operations. In particular, the derived wavelets can be “dilated” by a procedure comparable to the operation of steering steerable wavelets. The fundamental aspects of the construction are the same: an admissible collection of Fourier multipliers is used to extend ...

This paper is a survey of greedy randomized adaptive search procedures (GRASP). GRASP is a multi-start or iterative procedure where each GRASP iteration consists of a construction phase, where a feasible solution is constructed, followed by a local search procedure that finds a locally optimal solution. The construction phase of GRASP is essentially a randomized greedy algorithm. Repeated appli...

Equivalence operations for n-dimensional proper Hadamard matrices are defined. Their equivalence classes are investigated and bounds on the number of such equivalence classes are found to be associated with the number of equivalence classes of 2-dimensional Hadamard matrices. Properties of planes (2-dimensional sections) in an n-dimensional proper Hadamard matrix are investigated. It is shown t...
