BACKGROUND Surgeons have long debated the relative merits of vertical and inverted-T mammaplasties. These debates have centered on surgeons' opinions. Without measurements, this controversy is unlikely to be resolved. This study compares these common techniques using a recently published measurement system. Such a study using measurements on photographs matched for size and orientation has not ...

The BSS, which has been used in all City's TREC experiments, is a set-oriented ranked output system designed primarily for probabilistic{type retrieval of textual material using inverted indexes. There is a family of built-in weighting functions as described in [1, Section 3]. In addition to weighting and ranking facilities it has the usual boolean and quasi-boolean (positional) operations. The...

Forwarding is a tool for constructing stabilizers for nonlinear systems. A key step in this design technique is to find an explicit solution to a partial differential equation (PDE), which may be hard to find—actually, the PDE may even not be solvable at all. In this brief note we show that it is possible to provide an additional degree of freedom for the solution of the aforementioned PDE, hen...

For 3D walking control of a biped robot we analyze the dynamics of a three-dimensional inverted pendulum in which motion i s constrained to move along an arbitrarily defined plane. This analysis leads us a simple linear dynamics, the Three-Dimensional Linear Inverted Pendulum Mode (SD-LIPM). Geometric nature of trajectories under the 3D-LIPM and a method for walking pattern genemtion are discus...

Index preparation is a tedious and time-consuming task. This paper indicates how the indexing process can be automated in a way that is largely independent of a specific typesetting system and independent of the format being used. Fundamental issues related to this process are identified and analyzed. Specifically, we develop a framework for placing index commands in the document. In addition, ...

We consider a non-interacting gas under the inverted harmonic potential and present infinitely degenerate non-stationary orthogonal states. discuss that it has an infinite entropy at absolute zero temperature. show uncertainty in position of particle can be as there exists solution which asymptotes to Dirac delta function. obtain new free wave packet using eigenstates for potential. It unique s...

In this paper, robust stabilization of an experimental system is considered. This system consists of a pendulum free to rotate 360 degrees that is attached to a cart. The cart can move in one dimension. The linearized model of the system is used and transformed to a linear diagonal form. The system is separated into slow and fast subsystems. The fast dynamics are treated as a disturbance and th...
