In this paper we calculate the Bogoliubov coefficients and the energy density of the stochastic gravitational wave background for a universe that undergoes inflation followed by radiation domination and matter domination, using a formalism that gives the Bogoliubov coefficients as continous functions of time. By making a reasonable assumption for the equation of state during reheating, we obtai...

Current WWW clients do not directly support synchronized playback of continuos media. It is however possible to support continous media by using external programs that are controlled by the WWW client. This paper describes the design and implementation of a “Media on Demand” server which uses WWW as its user interface. Offered media include audio and video recordings of transmissions on the Int...

We present a reliable, narrow-linewidth (100-kHz) continous-wave optical parametric oscillator (OPO) suitable for high-resolution spectroscopy applications. The singly resonant OPO with a resonated pump is based on periodically poled lithium niobate crystal and features a specially designed intracavity etalon, which permits precise tuning to any desired wavelength in a wide range. We demonstrat...

FA equipment's such as Numerical Control [3,4] machine tools, industrial robots, aiid other automated machinery are used to save energy and promote automation , which allow for high productivity and also produces quality products . The aforementioned FA equipment's is becoming more technical with the application of servo motor and motion control technologies [5 ,6,7] . Rolf Johansoon presents a...

Male rats exposed to continous light for 70 days showed an increased weights of testis, accessory sex organs, serum levels of FSH, LH, testosterone, testicular 17beta-hydroxysteroid dehydrogenase (1beta-HSD) activity and alpha 2u-globulin, while 3beta-hydroxysteroid dehydrogenase activity showed no significant changes. Prolonged light exposure also stimulated sepermatogenesis in rats. These res...

In this paper we give a simple proof of inequalities of integrals of functions which are the composition of nonnegative continous convex functions on a vector space R and vector-valued functions in a weakly compact subset of a Banach vector space generated by m Lμ-spaces for 1 ≤ p < +∞. Also, the same inequalities hold if these vector-valued functions are in a weakly* compact subset of a Banach...

We introduce an e cient algorithm to compute the homomorphism induced in (relative) homology by a continous map.

and Applied Analysis 3 2. Preliminaries and Several Lemmas Definition 1. LetE be a real Banach space. A nonempty closed set P ⊂ E is said to be a cone provided that (1) au + bv ∈ P for all u, v ∈ P and all a ≥ 0, b ≥ 0, (2) u, −u ∈ P implies that u = 0. Definition 2. A map α : P → [0, +∞) is said to be concave on P, if α(tu + (1 − t)v) ≥ tα(u) + (1 − t)α(v) for all u, v ∈ P and t ∈ [0, 1]. Let ...

To enable robots to cope with unforeseen situations, as well as the noise and variation inherent in the real world, we believe it is essential to incorporate plasticity into robot controllers, and use as little predeened knowledge as possible. We present rst results of experiments in autonomous competence acquisition with \FortyTwo", a mobile robot equipped with tactile, sonar, infrared and vis...
