The TISPAN workgroup inside ETSI is currently working on accommodating the IMS (IP Multimedia Subsystem) architecture, which has been created for the mobile world, to the fixed scenario where there is a new important element to be taken into account: the Residential Gateway (RGW). This element is typically considered as a customer device where providers do not usually have anything to configure...

PURPOSE To assess the accuracy of a formula derived from 159 living liver donors to estimate the liver size of a normal subject: standard liver weight (g) = 218 + body weight (kg) × 12.3 + 51 (if male). Standard liver volume (SLV) is attained by a conversion factor of 1.19 mL/g. METHODS The total liver volume (TLV) of each of the subsequent consecutive 126 living liver donors was determined u...

As the strong evidence for inflation, the relic gravitational waves (RGW) have been extensively studied. Although, it has not been detected, yet some constraints have been achieved by the observations. Future experiments for the RGW detection are mainly two kinds: the CMB experiments and the laser interferometers. In this paper, we study these current constraints and the detective abilities of ...

In this paper we briefly present our works on the relic gravitational waves (RGW) and the CMB polarization in the accelerating universe. The spectrum of RGW has been obtained, showing the influence of the dark energy. Compared with those from non-accelerating models, the shape of the spectrum is approximately similar, nevertheless, the amplitude of RGW now acquires a suppressing factor of the r...

In the inflation cosmic models, the relic gravitational waves (RGW) generated in the inflation stage, and evolved in the universe until now. In the different cosmic evolution models, one can get different gravitational waves spectrum. In this paper, we give a simple formula to estimate the spectrum in a general cosmic model. From this spectrum, one can easily find the relation between the RGW s...

As the “smoking-gun” evidence for inflation, the relic gravitational waves (RGW) have been studied by a lot of authors. Although, it hasn’t been detected until now, some constraints have been achieved by the observations. Future experiments for the RGW detection are mainly two kinds: the CMB (cosmic microwave background radiation) experiments and the laser interferometers. In this paper, we stu...

In this paper, by solving the inflationary flow equations, we study the constraints on the relic gravitational waves (RGW) from the observations at large scale, i.e. cosmic microwave background radiation (CMB) and large scale structure (LSS), and those at small scale, i.e. the pulsar timing, LIGO, and big bang nucleosynthesis (BBN). We find that the current constraints on the RGW from small sca...

Let F and Fm be the usual spaces of n-dimensional column and m-dimensional row vectors on F, respectively, where F is the field of real or complex numbers. In this paper, the relations gsmajorization, lgw-majorization, and rgw-majorization are considered on F and Fm. Then linear maps T : F → F preserving lgw-majorization or gs-majorization and linear maps S : Fn → Fm, preserving rgw-majorizatio...

It is sometimes believed that a “broadband access” network, providing ample transmission capacity to residential environments, is enough so as to allow a flawless delivery of advanced services. However, the provisioning of a combination of multiple services with guaranteed quality up to the end-user terminal requires a carefully designed architecture incorporating the appropriated Quality of Se...
