The goal of this investigation is to study the effect of wing sweep angle on the horizontal wing-body- tail configurations in subsonic flow. For this purpose, a series of wind tunnel tests were conducted on a model having a moveable horizontal tail and a wing planform with different sweep angles. Tests were performed at different tail deflection angles. Static surface pressure distribution over...

Recently lexicographic breadth first search (LexBFS) has been shown to be a very powerful tool for the development of linear time, easily implementable recognition algorithms for various families of graphs. In this paper, we add to this work by producing a simple two LexBFS sweep algorithm to recognize the family of cographs. This algorithm extends to other related graph families such as P4-red...

We give an algorithm that learns a representation of data through compression. The algorithm 1) predicts bits sequentially from those previously seen and 2) has a structure and a number of computations similar to an autoencoder. The likelihood under the model can be calculated exactly, and arithmetic coding can be used directly for compression. When training on digits the algorithm learns filte...

We examine the problem of pushing all the points of a planar region into one point using parallel sweeps of an infinite line, minimizing the sum of the lengths of the sweep vectors. We characterize the optimal 2-sweeps of triangles, and provide a linear-time algorithm for convex polygons.

We present a sweep-based approach to modeling and deformation of three-dimensional objects. We approximate the deformable parts of an object using sweep surfaces. The vertices on the object boundary are bound to the sweep surfaces and then follow their deformation. For practical applications, we apply this approach to 3D human body modeling and deformation, and then extend it to the freeform de...

Data warehouses (DW) are built by gathering information from several information sources (ISs) and integrating it into one repository customized to users' needs. Recent work has begun to address the problem of view maintenance of DWs under concurrent data updates of diierent ISs. SWEEP proposed by Agrawal et al. AAS97] is one of the more popular solutions; even though its performance is limited...

Recently a new type of algorithms for numerical simulations of models with dynamical fermions has been proposed by M. Lüscher [1]. The idea is based on the approximation of a fermionic determinant by the path integral over some number of bosonic fields, which allows ones to elegantly avoid the main difficulty coming from the nonlocality of the fermionic determinant. The complexity of a sweep of...
