This paper presents a work in progress for the developing of a fingerprint indoor position system based on OpenMAC, an IEEE 802.15.4 embedded software implementation from Atmel to be used in different scenarios like e_health, ambient living or smart building. The system is thought to work as another one that we have yet developed but using the BitCloud(More)
Since the electric generating, distributing and marketing has been possible; the Electric Meter was introduced and developed along the years, but never like this time. The digital technology, the wireless communication, and the computer systems have dramatically changed the Electric meter generation from Traditional Meter to Automatic Meter and now to Smart(More)
The paper studies convergence properties of numerical optimization algorithms using the natural idea of searching in several directions and where one-processor computation is assumed. Global convergence theorems (with exact arithmetic) are proved for two classes of "descent" methods in IR n and for one class of such methods in Hilbert spaces in the(More)
Solutions in the field of Ambient Assisted Living (AAL) do not generally use standards to implement a communication interface between sensors and actuators. This makes these applications isolated solutions because it is so difficult to integrate them into new or existing systems. The objective of this research was to design and implement a prototype with a(More)
Body Area Networks are a solution to remote monitoring in order to acquire vital signals of patients. Actual sensors provide its own interface which makes more difficult to integrate them in a system. Using standardized protocols and interfaces increases the usability and the integration of different sensors, to achieve this goal the IEEE 1451 standard has(More)
1 ABSTRACT This work is concerned with the performance of adaptive filters with both poles and zeros in active noise control (ANC) applications. This filtered-error type of applications makes it necessary to modify classical adaptive algorithms to cancel the noise. Thus, a well established theory exists for filtered-error adaptive FIR filters, with a(More)
