In this paper a new method of handwritten characters recognition is introduced. The proposed algorithm is applied to classification of post mails on the basis of zip code information. In connection with this work the research was conducted with numeric characters used in real post code of mail pieces. Moreover article contains basic image processing for instance filtration binarization and norm...

This paper assesses the design guidelines of different classification codes for the liquefied natural gas carriers considering the effect of liquid sloshing. With regard the increasing importance of LNG carriers in today’s marine transportation, and also considering that the marine accidents involve significant loss, classification societies by regulating national and international standards ai...

The recent growth in network usage has motivated the creation of new malicious code for various purposes, including economic ones. Today’s signature-based anti-viruses are very accurate, but cannot detect new malicious code. Recently, classification algorithms were employed successfully for the detection of unknown malicious code. However, most of the studies use byte sequence n-grams represent...

OBJECTIVE To analyze deaths from external causes and undefined causes in women of childbearing age occurring during pregnancy and early postpartum. METHODS The deaths of 399 women of childbearing age, resident in Recife, Northeastern Brazil, in the period 2004 to 2006, were studied. The survey utilized the Reproductive Age Mortality Survey method and a set of standardized questionnaires. Data...

-In this paper we consider a technique for pattern classification based upon the development of prototypes which capture the distinguishing features ("disjunctive prototypes") of each pattern class and, via cross-correlation with incoming test images, enable efficient pattern classification. We evaluate such a classification procedure with prototypes based on the images per se (direct code), Ga...

Active Networking is an innovative technology which can open the network and make it more flexible. But, introducing active code within the network increases the network vulnerability from security point of view. The security is always considered as a separated component or an upper layer of the active network architecture. In this paper, we develop a global security architecture for a safe cod...

In this paper, we investigate the structure of cyclic codes over the ring F3 + vF3 where v2 = 1 and F3 = {0, 1, 2}. We prove that cyclic codes over the ring are principally generated, and give the generator polynomial of cyclic codes over this ring. Mathematics Subject Classification: 94B05

We provide useful results on two classes of convolutional codes: binary codes and nonbinary codes. The best codes or the best known codes for these two classes of convolutional codes are found by computer search. Some of them are better than those found in the past. We specify these codes by their transfer function matrices, distance spectra, and information-weight spectra. Furthermore, we deri...

A classification theory is developed for pairs of simple closed curves (A,B) in the sphere S, assuming that A ∩ B has finitely many components. Such a pair of simple closed curves is called an SCC-pair, and two SCC-pairs (A,B) and (A′, B′) are equivalent if there is a homeomorphism from S to itself sending A to A′ and B to B′. The simple cases where A and B coincide or A and B are disjoint are ...
