Combined phase I—phase II methods of feasible directions

Mathematical Programming, 1979
This paper presents several new algorithms, generalizing feasible directions algorithms, for the nonlinear programming problem, min{f 0 (z) ∣f j (z) ≤ 0,j = 1, 2, ⋯ ,m}. These new algorithms do not require an initial feasible point.

Feasibility of Motion Planning on Directed Graphs

2009
Because of irreversibility of movements, motion planning on directed graphs is much more intricate than that on graphs. Recently we showed that the feasibility of motion planning on acyclic and strongly connected directed graphs can be decided in time O (nm ) (n ,m are respectively the number of vertices and arcs of the directed graph), but left the ...

Constrained Variable Metric Method With Feasible Directions

16th Design Automation Conference: Volume 2 — Optimal Design and Mechanical Systems Analysis, 1990
Abstract This paper proposes a new feasible direction algorithm based on the constrained variable metric method of Powell in order to handle the design optimization problmes which demand that all iterative points are feasible. The algorithm retains many advantages of the constrained variable metric method, makes use of the properties of ...

Direct conversion for FLEX paging receivers-a feasibility study

1998 IEEE MTT-S International Microwave Symposium Digest (Cat. No.98CH36192), 2002
To achieve an integrated solution for the 6400 bps FLEX paging receiver, we examined the direct conversion architecture and addressed two major problems that may obstruct the implementation: (1) the compensation of the DC offset, and (2) the design of a 4-level FSK demodulator at zero-IF.

Directed Energy Weapons — Feasibility and Effectiveness

1983
Physicists have known for many years that either a collimated beam of charged or neutral elementary particles or of coherent monochromatic light can carry potentially destructive amounts of energy, capable under certain circumstances of melting or cracking metal, over distances measured in hundreds or thousands of kilometres.

Feasibility Study of a Direct Endo-Aortic Clamp Balloon

ASAIO Journal, 2007
We have developed a new end-aortic clamp balloon catheter intended to be inserted directly into, thereby occluding, the ascending aorta. We examined the performance of this catheter in a canine model. We evaluated the extent of migration tolerance of the catheter under cardiopulmonary bypass perfusion in 12 mongrel dogs, weighing 20 kg, under general ...

Feasible direction methods for stochastic programming problems

Mathematical Programming, 1980
A unified approach to stochastic feasible direction methods is developed. An abstract point-to-set map description of the algorithm is used and a general convergence theorem is proved. The theory is used to develop stochastic analogs of classical feasible direction algorithms.

[Direct stent implantation: feasibility, advantages and disadvantages].

Anadolu kardiyoloji dergisi : AKD = the Anatolian journal of cardiology, 2002
Coronary stent implantation was firstly performed as only a bail-out procedure for poor angioplasty results, but nowadays it has become a primary modality of coronary revascularization. The deployment of intracoronary stents during percutaneous transluminal coronary angioplasty has been shown in a number of clinical trials to provide additional ...
