Ethical Considerations on Nanotechnology
Manuel Alberto M. Ferreira, José António Filipe
Since a significant time ago, although time runs very fast,nanotechnology transformed from one of the most promising scientific hopes in uncountable human domains into a marvelous…
Nanotechnology and Processes The NanoPhotovoltaic Panels
Manuel Alberto M. Ferreira, José António Filipe, José Chavaglia Neto
Nanotechnology may work as a powerful weapon to be used for creating competitive advantages in the energy market. Using the photovoltaic nano-panels, which may reduce considerably…
Preferences Relations and Consumer Theory
Manuel Alberto M. Ferreira, José António Filipe
In this paper an interesting application of mathematics in economics is presented: the formulation of the theory of consumer basic problem, grounded on the concept of preferences r…
Infinite Servers Queue Systems Busy Period Time Length Distribution and Parameters Study through Computational Simulation
Manuel Alberto M. Ferreira
A FORTRAN program to simulate the operation of infinite servers queues is presented in this work. Poisson arrivals processes are considered but not only. For many parameters of int…
Networks of Queues Models with Several Classes of Customers and Exponential Service Times
Manuel Alberto M. Ferreira
The main target of this paper is to present the Markov chain C that, not giving explicitly the queue lengths stationary probabilities, has the necessary information to its determin…
Stochastic Processes in Networks of Queues with Exponential Service Times and only one Class of Customers
Manuel Alberto M. Ferreira
Two networks of queues models, presented initially by Jackson, in the open case, and Gordon and Newell, in the closed case, stochastic processes are presented and studied in some o…
