As a part of our new research activity aiming at a detailed understanding of space charge effects in ring cyclotrons and in the corresponding injection beam lines at the Paul Scherrer Institute we are currently developing a three dimensional space charge simulation code. The use of the Hamiltonian formalism, in combination with a symbolic algebra system (MAPLE), enables us to carry out the enti...

Three-dimensional Oximetric Electron Paramagnetic Resonance Imaging using the Single Point Imaging modality generates unpaired spin density and oxygen images that can readily distinguish between normal and tumor tissues in small animals. It is also possible with fast imaging to track the changes in tissue oxygenation in response to the oxygen content in the breathing air. However, this involves...

The problem solving environments (PSEs) Maple [8] and Matlab [7] are in very wide use. Although they have much in common, they are clearly distinguished by the emphasis in Maple on algebraic computation and in Matlab on numerical computation. We discuss here a program, IVPsolve, for solving numerically initial value problems (IVPs) for systems of first order ordinary differential equations (ODE...

The development of optimized codes is time-consuming and requires extensive architecture, compiler, and language expertise, therefore, computational scientists are often forced to choose between investing considerable time in tuning code or accepting lower performance. In this paper, we describe the first steps toward a fully automated system for the optimization of the matrix algebra kernels t...

In this paper we estimate the performance of 2*4 MIMO-MC-CDMA system using convolution code in MATLAB which highly reduces BER. MC-CDMA (Multi Carrier Code Division for Multiple Access) is a multi-user and multiple access system which is formed by the combination of OFDM and CDMA and convolution encoding scheme is used in encoder of CDMA as FEC (Forward Error Correction) code to reduce BER (Bit...

This paper deals with the problem of statically inferring the shape of an array in languages such as MATLAB. Inferring an array’s shape is desirable because it empowers better compilation and interpretation; specifically, knowing an array’s shape could permit reductions in the number of run-time array conformability checks, enable memory preallocation optimizations, and facilitate the in-lining...

This paper describes the model-based development process of hard real-time software with the Timing Definition Language (TDL): modeling and simulation of TDL components in Matlab®/Simulink®, their mapping to a specific platform and finally the code generation.

In der modellbasierten Entwicklung eingebetteter Software, insbesondere im Automobilbereich, wird Matlab/Simulink verbreitet eingesetzt. Im Rahmen der Modellerstellung, -wartung und -pflege häufig benötigte Änderungen an den Modellen, wie die Restrukturierung der Modellstruktur und Generierung von Modellkonstrukten, werden überlicherweise manuell, mit den vorhandenen Modellierungsmitteln des Si...

This paper presents an overview ofthe FALCON MATLAB-to-Fortran 90 compiler. FA~CON is a programming environment for the development of high-performance scientific programa. It combines static and dynamic inference methods to translate MATLAB programa into Fortran 90. The statit inference is supported with advanced value propagation techniques and symbolic algorithms for subscript analysis. The ...
