The Snyder-de Sitter model is an extension of the Snyder to a de background. It called triply special relativity (TSR) because it based on three fundamental parameters: speed light, Planck mass, and cosmological constant. In this paper, we study dimensional DKP oscillator for spin zero one in framework algebra momentum space. By using technique vector spherical harmonics energy spectrum corresp...

Maintaining the genetic diversity in populations is an important issue when dealing with dynamic environments. In this paper we use a modified Genetic Algorithm (GA) to solve the 0/1 Dynamic Knapsack Problem (DKP). The proposed GA uses a biologically inspired genetic operator instead of the classical crossover operator. The proposed genetic operator is capable of maintaining the genetic variati...

This paper proposes a Deterministic Kinodynamic Planning approach (DKP for short) offering the degree of generality of randomized techniques for two wheeled robots, such as RRT, but also guarantees on the computation time. This approach combines a global path planner based on an A∗-like algorithm, and a local motion planner based on spline optimization techniques. Implementation details and com...

A procedure for the cyclization of dipeptidoyl benzotriazolides containing proline derivatives promoted by triethylamine under MW activation is introduced. The reaction is general for a variety of dipeptidoyl benzotriazolides and represents a very practical and convenient method for the preparation of Pro- or Hyp-derived 2,5-diketopiperazines (2,5-DKPs) and bis-DKPs with a disulfide linker. Thi...

A new method for the determination of the active principle dexketoprofen (DKP) in a hydrogel using near infrared spectrometry was developed. A transflectance module allows the gel spectrum to be recorded with no sample pretreatment. Also, the PLS calibration method used allows low contents of the active principle in such a highly absorbing matrix as water/ethanol to be determined. The proposed ...

We have recently solved the inverse scattering problem for one parameter families of vector fields, and used this result to construct the formal solution of the Cauchy problem for a class of integrable nonlinear partial differential equations connected with the commutation of multidimensional vector fields, like the heavenly equation of Plebanski, the dispersionless Kadomtsev Petviashvili (dKP)...

Interpretation of dispersionless integrable hierarchies as equations of coisotropic deformations for certain associative algebras and other algebraic structures is discussed. It is shown that within this approach the dispersionless Hirota equations for dKP hierarchy are nothing but the associativity conditions in a certain parametrization. Several generalizations are considered. It is demonstra...
