The 3‐D‐tongue FEM model revised

The PFTK-model revised

This paper presents an analytical model of TCP Reno throughput as a function of loss event rate, average round trip time, average retransmission timeout value, and receiver window size based on the model proposed by Padhye et al. (widely known as the PFTK-model in correspondence with the initials of the authors). The presented model refines previous work by careful examination of fast retransmi...

Model reduction for efficient FEM/BEM coupling

Model reduction techniques seek approximate solutions of a problem with a large number of DOFs within a subspace of small dimension. Component Mode Synthesis (CMS) methods form a large class of reduction methods where the subspace is selected a priori. Introducing a posteriori error estimation and iterative correction significantly extends the range of applications of reduction methods. The pap...

Extended Entity - Relationship Model ( revised

We present the hybrid query language HQL/EER for an Extended Entity-Relationship model. As its main characteristic, this language allows a user to use both graphical and textual elements in the formulation of one and the same query. We demonstrate the look-and-feel of this query language by means of examples, and show how syntax and semantics of this language are formally deened using programme...

A revised dynamic otolith model.

FEM Implementation of the Coupled Elastoplastic/Damage Model: Failure Prediction of Fiber Reinforced Polymers (FRPs) Composites

The coupled damage/plasticity model for meso-level which is ply-level in case of Uni-Directional (UD) Fiber Reinforced Polymers (FRPs) is implemented. The mathematical formulations, particularly the plasticity part, are discussed in a comprehensive manner. The plastic potential is defined in effective stress space and the damage evolution is based on the theory of irreversible thermodynamics. T...
