Space‐Time FEM Solution of Dynamic Contact Problem With Discontinuous Velocity for Multiple Impact of Deformed Bar Using PDAS Method

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT A class of one‐dimensional impact and dynamic contact problems taking into account non‐smooth velocities is studied. The new space‐time finite element approximation of dynamic variational inequalities is suggested. The non‐smooth solution for the impact of an obstacle by an elastic bar and its energy conservation under persistency conditions ...

Shape Derivatives of the Eigenvalues of the De Rham Complex for Lipschitz Deformations and Variable Coefficients: Part I

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We study eigenvalue problems for the de Rham complex on varying three‐dimensional domains. Our analysis includes the Helmholtz equation as well as the Maxwell system with mixed boundary conditions and non‐constant coefficients. We provide Hadamard‐type formulas for the shape derivatives under weak regularity assumptions on the domain and its ...

Deterministic elliptic curve primality proving for a special sequence of numbers

open access: yes, 2013
We give a deterministic algorithm that very quickly proves the primality or compositeness of the integers N in a certain sequence, using an elliptic curve E/Q with complex multiplication by the ring of integers of Q(sqrt(-7)). The algorithm uses O(log N)

The Weak Core, Partition‐Based Universal Stability, and Their Risk Associations Through A Partial Order

open access: yesNaval Research Logistics (NRL), EarlyView.
ABSTRACT We are concerned with the stability of a transferable‐utility cooperative (TU) game. First, the concept of core can be weakened so that the blocking of changes is limited to only those with multilateral backings. This principle of consensual blocking, as well as the traditional core‐defining one of unilateral blocking and one straddling in ...

Quantum Probabilistic Subroutines and Problems in Number Theory

open access: yes, 2000
We present a quantum version of the classical probabilistic algorithms $\grave{a}$ la Rabin. The quantum algorithm is based on the essential use of Grover's operator for the quantum search of a database and of Shor's Fourier transform for extracting the ...

Random Primes without Primality Testing

open access: yesProceedings of the 2022 International Symposium on Symbolic and Algebraic Computation, 2022
Numerous algorithms call for computation over the integers modulo a randomly-chosen large prime. In some cases, the quasi-cubic complexity of selecting a random prime can dominate the total running time. We propose a new variant of the classic D5 algorithm for "dynamic evaluation", applied to a randomly-chosen (composite) integer.

An Exact Method for Reliable Shortest Path Problems With Correlation

open access: yesNetworks, EarlyView.
ABSTRACT Shortest path problems often arise in contexts where travel times are uncertain. In these settings, reliable paths are often valued more than paths with lower expected travel times. This has led to several variants of reliable shortest path problems (RSPP) that handle travel time reliability differently. We propose an algorithmic framework for

Melodies of the forest: Nature as an improvisational space for shared creative embodiment

open access: yesPeople and Nature, EarlyView.
Abstract In an era marked by increasing disconnection from nature, innovative approaches to reconnect with the environment are crucial for both ecological and psychological well‐being. This paper explores how natural environments (a deciduous forest of Quebec in the present case study) can serve as an improvisational space for shared creative ...

Primality testing

open access: yes, 2013
With the boom in information technology and the penetration of these technologies in an increasing number of areas, such as electronic business, many questions about security arise. Data in electronic form bring many benefits, but they are vulnerable to various abuses. Therefore, data need to be adequately protected.
