Hydrodynamic model in isospin channels
Physical Review Letters, 1987The Steinwedel-Jensen hydrodynamic model is generalized to study isovector collective modes excited in charge-exchange reactions. Results are given for the energy splittings between the different isospin components of the giant dipole and monopole resonances recently observed in (p,n) and (..pi../sup +- /,..pi../sup 0/) reactions. The quenching of the .

Peptaibols: models for ion channels
Biochemical Society Transactions, 2001Peptaibols are membrane-active polypeptides isolated from fungal sources. They are characterized by the presence of an unusual amino acid, α-aminoisobutyric acid, and a C-terminal hydroxylated amino acid. Peptaibols exhibit antibiotic activity against bacteria and fungi. Their amphipathic nature allows them to self-associate into oligomeric ion-channel

Modelling mid‐channel bars in meandering channels
Earth Surface Processes and Landforms, 2010AbstractAn analytical modelling framework is proposed to reproduce the frequently observed but poorly studied occurrence of mid‐channel bars in meandering channels. Mid‐channel bars occur in meanders and may characterize transitional morphologies between pure meandering and braided rivers.

The Tuple Channel coordination model
Proceedings of PDSE '97: 2nd International Workshop on Software Engineering for Parallel and Distributed Systems, 2002We present a new coordination model and a small set of programming notations for distributed programming that can be integrated into very different programming languages (imperative, declarative or object oriented). Both together, allow distributed programs to be developed in a compositional way, by assembling different independent pieces of (possibly ...

Channel Modeling for V2V Communications
2006 Third Annual International Conference on Mobile and Ubiquitous Systems: Networking & Services, 2006In this paper we describe results of a channel measurement campaign for modeling the V2V channel. After review of applications, potential frequency bands, and related work, we describe the measurements and results for delay spreads and multipath component fading amplitudes and correlations, made in multiple V2V environments.

Statistical modeling of the LMS channel
IEEE Transactions on Vehicular Technology, 2001In this paper, a statistical model for the land mobile satellite (LMS) channel is presented. The model is capable of describing both narrow- and wide-band conditions. The other relevant characteristic is that it can be used to study links with geostationary as well as nongeostationary satellites. The model is of the generative type, i.e., it is capable

Converting SIRCIM Indoor Channel Model into SNR-Based Channel Model
2005The event-driven network simulation platforms, e.g. NS2 and GloMoSim, adopt some general wireless channel propagation models providing the pathloss of the channel as well as the SNR of each received packet to estimate the BER. However, these SNR-based general channel models give more accurate results for outdoor environments than indoor.

On formal modeling of communication channels
IEEE INFOCOM '89, Proceedings of the Eighth Annual Joint Conference of the IEEE Computer and Communications Societies, 1989A formal semantics of a model for a communication channel is given. The model is the foundation of a simulation package which can be used for modeling of communication phenomena in distributed physical systems. The software system based on the model can be viewed as an emulator for LAN-type communication networks.
