In this paper we study some properties of 3D objects such as compactness, the work done in object transformations and the number of voxels to be moved in order to normalize a similarity measure of an appropriate set of 3D objects. Voxel representation and scale normalization allow us to find the total distance of a set of voxels from one object to another. For these purposes, the comparison of ...

The Assignment algorithm is around 54 years old and a lot of work has been done on this algorithm. In this study various aspect of assignment algorithm has been considered. The endeavor of this note is to make solution of assignment problem so simple that even class tenth student can easily solve it. One of the most important aspects of assignment algorithm (Hungarian Algorithm) is to draw line...

In the pattern recognition context, objects can be represented as graphs with attributed nodes and edges involving their relations. Consequently, matching attributed graphs plays an important role in objects recognition. In this paper, a node signatures extraction is combined with an optimal assignment method for matching attributed graphs. In particular, we show how local descriptions are used...

In this paper, we consider each neural network as a point in a multi-dimensional problem space and suggest a crossover that locates the central point of a number of neural networks. By this, genetic algorithms can spend more time around attractive areas. We also apply representational normalization to neural networks to maintain genotype consistency in crossover. For the normalization, we utili...

Preverbal focus in Hungarian has been argued to be more exhaustive or exhaustive in a distinguished way as compared to what has been generally called prosodic focus in languages like English or German. In virtually all analysis it has been assumed that the reason for this property of Hungarian focus is related to its immediately preverbal syntactic position. This effect has thus been derived co...

Tobacco smoking became an important marker of Hungarian national identity during the nineteenth century. this national symbol ultimately had an economic origin: Hungarian tobacco producers resisted the tobacco monopoly of the Habsburg central government, and led an ultimately successful consumer boycott of Austrian products. Tobacco nationalism, however, became a common theme in Hungarian popul...

The school choice problem concerns the design and implementation of matching mechanisms that produce school assignments for students within a given public school district. In this note we define a simple student-optimal criterion that is not met by any previously employed mechanism in the school choice literature. We then use this criterion to adapt a wellknown combinatorial optimization techni...

Haxell’s condition [Hax95] is a natural hypergraph analog of Hall’s condition, which is a wellknown necessary and sufficient condition for a bipartite graph to admit a perfect matching. That is, when Haxell’s condition holds it forces the existence of a perfect matching in the bipartite hypergraph. Unlike in graphs, however, there is no known polynomial time algorithm to find the hypergraph per...

The accuracy of a crop model is judged mostly by how precise it is in estimating the production. The preciseness of a crop model is determined on one hand by the authenticity of the algorithms describing the processes of the real world, while on the other hand by the quality of its input data. The goal of this study was to test how sensitive crop models are to errors occurring in the measuremen...

In this paper we describe the specifications and results of UMCC_DLSI system, which was involved in Semeval-2014 addressing two subtasks of Semantic Textual Similarity (STS, Task 10, for English and Spanish), and one subtask of Cross-Level Semantic Similarity (Task 3). As a supervised system, it was provided by different types of lexical and semantic features to train a classifier which was use...
