Speech translation is a process of both speech recognition and equivalent phonemic to word translation. Accent is a pattern which differentiates the pronunciation and acoustic features based on the specific language group. The recognition and classification of words with different accent is also challenging problem in speech recognition research. There are many issues which limit the performance of such systems since a word spoken by different persons can have different acoustic properties due to variation in physiological characteristics, emotional status, and cultural background. Speech recognition is a process of identifying phonemes from the speech segment which is affected by the accent of the speaker. Some of the English words spoken by South Indian people whose native language being other than English like Telugu, Kannada, Tamil, Malayalam and Marathi, etc., will have a typical............

A single-stage-based integrated power electronic converter has been proposed for plug-in electric vehicles (PEVs). The proposed converter achieves all modes of vehicle operation, i.e. plug-in charging, propulsion and regenerative braking modes with wide voltage conversion ratio (M) [M < 1 as well as M > 1] in each mode. Therefore, a wide variation of battery voltage can be charged from the universal input voltage (90–260 V) and allowing more flexible control for capturing regenerative braking energy and dc-link voltage. The proposed converter has least components compared to those existing converters which have stepping up and stepping down capability in all modes. Moreover, a single switch operates in pulse width modulation in each mode of converter operation hence control system design becomes simpler and easy to implement. To correctly select the power stage switches, a loss analysis of the proposed converter has been investigated in ac/dc and dc/dc stages.

Key words: ZETA SEPIC, Dc -Dc Converter, Electric vehicle, State of Charge (Soc)

Electrical power disruptions have been a major limitation in our society Nigeria, as it has impact in our social-economical activities. This paper will critically examine the problems and costs related to the effect of power failures on commercial customers in Garden City Central Area of Port Harcourt, Rivers State. This work examine problems of electrical power transmission and distribution that influences power failures to commercial consumers with specific interest on mobile telecommunication firms within Garden City Central Area of Port Harcourt, Rivers State. Bearing in mind the model employed in analysis of power failures within Garden City Central Area, of Port Harcourt, Rivers State. It has been discovered that the power failure within the case study area is evenly distributed..........

The issue of viability is of great concern in our daily life. Since Eleme is becoming an industrial hub of Port Harcourt City and a preferred location for most of the industries, considerable share of the electric power supply should be directed towards the area. The people in Eleme have been faced with erratic power supply and this is associated with their livelihood; all power consumers are victims of the problem. Especially for factories and industries, it is really challenging to tolerate power interruption since it causes much revenue loss within hours of interruption. So the root cause of this problem should first be identified and the possible solution should be investigated...............

In today's world, securing data is becoming one of the main issues, the elaboration of the fusion of cryptography and steganography are contemplating as the sphere of on-going research. This can be gain by cryptography, steganography, and fusion of these two, where message firstly encoding using any cryptography techniques and then conceal into any cover medium using steganography techniques. Biological structure of DNA is used as the cover medium due to high storage capacity, simple encoding method, massive parallelism and randomness DNA cryptography can be used in identification card and tickets. Currently work in this field is still in the developmental stage and a lot of investigation is required to reach a fully-fledged stage. In this paper, we used modify DNA based Playfair as cryptography method. This paper provides analysis of capacity, payload, and bpn of proposed method used to hide DNA based Playfair cipher into DNA sequence.

Keywords: DNA , DNA Cryptography, Playfair, and substitution method.

Steganography is defined in terms of hidden or secret communication. It is hiding the presence of information or data from the unauthorized users. Therefore, we need a medium that hides the message or work as cover media for steganography. Many multimedia files such as Image, audio, video etc. are very frequently used for a cover medium in steganography. Other than these It Is also possible to use video games as the cover medium that makes a message more undetectable. In this paper we implementing the game based steganography methods. Therefore, Sudoku Puzzles are used as the cover medium. It is freely available online. The purpose of using this due to its hiding capacity and the popularity among the people availability and the hiding capacity.

Keywords: Steganography, Entropy, hiding capacity, Sudoku Puzzles.
