We propose a technique called Envelop-Matching for Time Scale Modification (EM-TSM). This technique is the modification of a technique called synchronized overlap-and-add (SOLA) [5] with the computation complexity significantly reduced. The reduction in computation complexity is useful the fast browsing of audio or video, which can be implemented by a general single-processor machine.

 This paper describes the transport session management (TSM) architecture and mechanisms for one-tomany multicast sessions. TSM is one of the crucial components for the multicast transport protocols, along with the reliability management. The main purpose of TSM is to maintain an active Transport Session stable and desirable. TSM is also extended to support the effective billing/charging and t...

Water having entered a stream channel from the surrounding catchment may continue to have connections with the catchment. In the stream’s hyporheic zone, water “in the channel” exchanges with “groundwater” in the bed of the stream. Hyporheic exchange flows typically occur at scales small relative to the length and volumetric transport characteristics of the stream. Nevertheless, it is well docu...

A new continuous finite-time control scheme for trajectory-tracking problem of robotic manipulators is proposed using terminal sliding mode (TSM). The finitetime convergence property of TSM is applied in both the reaching phase and the sliding phase of the sliding mode control system. As a result, the closed-loop system is globally finite-time stable and the trajectory-tracking objective is ach...

The absorption coefficient of phytoplankton, detrital material and coloured dissolved organic material and Chl a concentrations were collected during cruises in 2002 & 2003 under the framework of the European Research Contract The Regional Validation of MERIS chlorophyll products in North Sea coastal waters (REVAMP, EVG1-CT-200100049). Three campaigns were undertaken in coastal regions of the N...

This paper considers the location tracking problem in PCS networks. How a solution to this problem peflorms in fact highly depends on the mobility patterns of users [14]. In this paper; we propose a new Traveling Salesman Mobility (TSM) model, in hope of catching the mobility patterns of a large group of users. The TSM model is characterized by features of “stop-or-move ”, “infrequent transitio...

Abstract—We have incorporated the translational rotational (TR) coupling effects in the framework of three body force shell model (TSM) to develop an extended TSM (ETSM). The dynamical matrix of ETSM has been applied to compute the phonon frequencies of orientationally disordered mixed crystal (ND4Br)x(KBr)1-x in (q00), (qq0) and (qqq) symmetry directions for compositions 0.10≤x≤0.50 at T=300K....

The launch of Ocean and Land Colour Instrument (OLCI) on board Sentinel-3A in 2016 is the beginning of a new era in long time, continuous, high frequency water quality monitoring of coastal waters. Therefore, there is a strong need to validate the OLCI products to be sure that the technical capabilities provided will be used in the best possible way in water quality monitoring and research. The...

Assessing the impacts of environmental change and anthropogenic activities on the historical and current total suspended matter (TSM) pattern in Dongting Lake, China, is a large challenge. We addressed this challenge by using more than three decades of Landsat data. Based on in situ measurements, we developed an algorithm based on the near-infrared (NIR) band to estimate TSM in Dongting Lake. T...
