In this paper we present a very simple derivation of the constants of motion for dynamical systems, which requires only an elementary knowledge of the theory of continuous groups. In addition, through the infinitesimal Lorenz transformations group, we obtain a…

Asistimos en los últimos años a un cambio en la forma de competir de las empresas. Frente a una visión individual y aislada de la competencia, se impone actualmente la responsabilidad colectiva en el marco de relaciones y redes de…

A two-dimensional Laplace equation is separable in elliptic coordinates and leads to a Chebyshev-like differential equation for both angular and radial variables. In the case of the angular variable η (-1 < η < 1), the solutions are the well…

The article discusses basic teaching-learning philosophies and experiences from the development and testing of mobile learning integrated with the online distance education system at NKI (Norwegian Knowledge Institute) Distance Education. The article builds on experiences from three European Union (EU)…

The book is about diagnostic ultrasound imaging authored by Dr. Thomas L. Zabo. Graduate students in medical physics and biomedical engineering with backgrounds in calculus, complex numbers and some knowledge on electric circuits would benefit from this book.

En este trabajo se presenta el diseño e implementación de una ontología para el dominio del análisis del semen humano, cuyo objetivo es representar, organizar, formalizar y estandarizar el conocimiento del dominio, para que éste pueda ser compartido y reutilizado…

\Since the start of the current millennium, experience and expertise in the development and delivery of mobile learning have blossomed and a community of practice has evolved that is distinct from the established communities of 'tethered' e-Learning. This community is…
