Numeral recognition is the process to classify the given character according to the predefined character class. This paper proposed a methodology for recognizing Bangla handwritten numerals which are based on fuzzy logic theory due to its low computational requirement. Every numeral is segmented and several features are extracted for each segment. In this paper, we use unique fuzzy rule base for each...
A Gaussian multiple input multiple output (MIMO) channel is considered where a transmitter is communicating to a receiver in the presence of an eavesdropper. The transmitter is equipped with multiple antennas, while the receiver and the eavesdropper also contains multiple antennas. We present a technique for determining the secrecy capacity of the MIMO channel under Gaussian noise. To do so, we transform...
A good understanding of programming language can be developed and understood in a machine independent manner called structural operational semantics. It is a mathematical model for specifying the meaning of a language by defining the effect of a running program in terms of its structure. The emphasis of this work is to present the structural operational semantics of several important aspects of packages...
Although conventional cryptographic security mechanisms are essential to the overall problem of security, the openness of wireless medium poses both threats and opportunities for securing transmission. Information theoretic security is attracting researchers for its robust nature. In this paper, a Gaussian multiple input multiple output multiple eavesdropper (MIMOME) channel is considered where a...
This paper presents a fuzzy based Bangla vowel sign recognition system. Vowel and consonant are the main criteria to express any language. Exceptionally, Bangla has some vowel sign which are used to express Bangla word. Therefore, to recognize any Bangla word, at first it is necessary to recognize which vowel sign is used to express that word. Due to its low computational requirement and very high...
Generally phrasal verbs comprise a verb followed by a preposition that is commonly occurring feature in English. Each of the phrasal verbs acquires absolutely different meanings in different contexts. Having highly context dependent meanings, phrasal verbs may be disambiguated only by devising a technique involving utilization of semantic information pertaining to the context. This paper presented...
Vessel, fovea and optic disk are the three most important features of human retina that are frequently used for retinal image registration, illumination correction as well as for pathology detection inside retina. In this paper, we present a fully automated approach that can detect and localize these organs from retinal fundus image effectively. For vessel detection, we have adopted an exploratory...
