Inclusion diagrams are introduced as an alternative to using Venn diagrams to determine the validity of categorical syllogisms, and are used here for the analysis of diverse categorical syllogisms. As a preliminary example of a possible generalization of the use of inclusion diagrams, consideration is given also to an argument that includes more than two(More)
The results obtained by analyzing signals with the Square Wave Method (SWM) introduced previously can be presented in the frequency domain clearly and precisely by using the Square Wave Transform (SWT) described here. As an example, the SWT is used to analyze a sequence of samples (that is, of measured values) taken from an electroencephalographic(More)
A novel Mathematical Random Number Generator (MRNG) is presented here. In this case, ”mathematical” refers to the fact that to construct that generator it is not necessary to resort to a physical phenomenon, such as the thermal noise of an electronic device, but rather to a mathematical procedure. The MRNG generates binary strings – in principle, as long as(More)
A brief review is provided of the use of the Square Wave Method (SWM) in the field of signal and image analysis and it is specified how results thus obtained are expressed using the Square Wave Transform (SWT), in the frequency domain. To illustrate the new approach introduced in this field, the results of two cases are analyzed: a) a sequence of samples(More)
This is a variation of a previously presented method [1] for characterizing the shapes of plane figures. In addition to retaining the advantages of the original method, this variant includes one more: It is no longer necessary to halt a (simulated) diffusion process during the transient stage; that is, before arriving at an equilibrium. On the contrary, the(More)
In the experiment on 15 mongrel dogs, the pancreatoduodenal resection (PDR) with cholecystopancreatoanastomosis (CPA) formation was modelled. The advantages of CPA over pancreatojejunostomy were confirmed by morphological and histochemical investigations. In the institute of Clinical and Experimental Surgery, from 1983 to 1987, 73 PDRs were performed with(More)
