Proximal Analysis and the Minimal Time Function∗

چکیده
Under general hypotheses on the target set S and the dynamics of the system, we show that the minimal time function TS(·) is a proximal solution to the Hamilton–Jacobi equation. Uniqueness results are obtained with two different kinds of boundary conditions. A new propagation result is proven, and as an application, we give necessary and sufficient conditions for TS(·) to be Lipschitz continuous near S. A Petrov-type modulus condition is also shown to be sufficient for continuity of TS(·) near S.

Determination of a Matrix Function in the Form of f(A)=g(q(A)) Where g(x) Is a Transcendental Function and q(x) Is a Polynomial Function of Large Degree Using the Minimal Polynomial
Matrix functions are used in many areas of linear algebra and arise in numerical applications in science and engineering. In this paper, we introduce an effective approach for determining matrix function f(A)=g(q(A)) of a square matrix A, where q is a polynomial function from a degree of m and also function g can be a transcendental function. Computing a matrix function f(A) will be time- consu...
متن کاملChronic Proximal Biceps Tendinitis in Young Patients with Anatomic Proximal Origin Variations: A case series
Purpose: To describe a case series of young adult patients with isolated chronic proximal biceps tendinitis refractory to conservative care found to have anatomic long head biceps tendon (LHBT) origin variations who underwent arthroscopic-assisted subpectoral biceps tenodesis.

Complete traumatic maior amputation of through proximal Humerus is extremely rare. Selection of a amputated limb for replantation is based on the type, time, location, age, and underling disease of patients. There are many factors which control the functional prognosis of reattached arms. The most important factors are the level of amputation, the severity of crush, ischemic time, and the age o...
متن کاملMaintenance Cost Analysis for Replacement Model with Perfect Minimal Repair
With the evolution of technology, the maintenance of sophisticated systems is of concern for system engineers and system designers. The maintenance cost of the system depends in general on the replacement and repair policies. The system replacement may be in a strictly periodic fashion or on a random basis depending upon the maintenance policy. At failure, the repair of the system may be perfor...
متن کاملConservative management with external coaptation technique for treatment of a severely comminuted fracture of the proximal phalanx in a Holstein-Friesian cow
A 3-year-old Holstein-Friesian cow was evaluated because of sudden onset of right hind limb lameness and pain with fetlock swelling for 2 days. Based on the history, clinical index scores and computed radiographic examinations, the case was accurately diagnosed to be a severely comminuted fracture of the proximal phalanx. This cow was assigned for conservative treatment with external coaptation...
