AbstractThe enhanced frequency based keypad is designed to speed up the typing
process. This paper will show that the proposed layout will increase the typing
speed and be flexible for thumb. Traditional cell phone keypad is not a
scientific keypad from the frequency point of view. Approaches have been
explored to speed up the typing process. We found that no manufacturer has
considered the frequency of the alphabet. The current architecture does not
provide flexibility although the users are accustomed to the currently
available multi-tapping keypad.An Efficient Technique for Text Compression.

AbstractFor storing a word or the whole text segment, we need a huge storage space.
Typically a character requires 1 Byte for storing it in memory. Compression of
the memory is very important for data management. In case of memory requirement
compression for text data, lossless memory compression is needed. We are
suggesting a lossless memory requirement compression method for text data
compression. The proposed compression method will compress the text segment or
the text file based on two level approaches firstly reduction and secondly
compression.Smart Bengali Cell Phone Keypad Layout.

AbstractNowadays cell phone is the most common communicating used by mass people. SMS
based communication is a cheap and popular communication method. It is human
tendency to have the opportunity to write SMS in their mother language. Text
input in mother language is more flexible when the alphabets of that language
are printed on the keypad. Bangla mobile keypad based on phonetics has been
proposed earlier. But the keypad is not scientific from frequency and
flexibility point of view.A Unique 10 Segment Display for Bengali Numerals.

AbstractSegmented display is widely used for efficient display of alphanumeric
characters. English numerals are displayed by 7 segment and 16 segment display.
The segment size is uniform in this two display architecture. Display
architecture using 8, 10, 11, 18 segments have been proposed for Bengali
numerals 0...9 yet no display architecture is designed using segments of
uniform size and uniform power consumption. In this paper we have proposed a
uniform 10 segment architecture for Bengali numerals. This segment architecture
uses segments of uniform size and no bent segment is used.
