The software testing state of practice is not as good as it ought to be. To reduce the gap between the state of practice and the state of the art, improvement of software testing is necessary. Existing improvement models focus too little on, or lack important aspects of, software testing. Therefore a new model is required. This paper describes a test(More)
Joint optimization of transmitting and receiving filters in pulse-amplitude-modulated stationary Gaussian channels has been considered by a large number of authors under a variety of different circumstances. In most cases it has been found that the optimum filters are strictly band limited. In the present correspondence we give a direct argument why this(More)
Recent developments of single molecule detection techniques and in particular the introduction of fluorescence correlation spectroscopy (FCS) led to a number of important applications in biological research. We present a unique approach for the gene expression analysis using dual-color cross-correlation. The expression assay is based on gene-specific(More)
V. Ramamoorthy and Thomas Ericson The University of Linköping, Linköping, Sweden A composite-Gaussian model of speech is presented. This model takes into account many different modes of speech and lends itself for coding with Gaussian source coders. The problems associated with coding of this source are discussed. A mode detector is derived for a special(More)
