In this research a simple yet efficient means of generating quadruped animation using trigonometric based mathematical equations with expressions were discussed. The technique proposed through this research is based on two tier animation control curve. The base simulation is driven through procedural model using trigonometric sinus and cosine functions to generate a sinusoidal motion curve with control parameters. The trigonometric sinus and cosine functions are used with control attributes to produce involuntary, procedurally generated base animation. In the top layer, animation is manipulated and customized by the animator through custom user controllable manipulators. These manipulators are created through an automated procedural rigging technique, based on forward and inverse kinematics controls. The User is provided with various attributes to control the locomotion gaits and create varying types of gaits from walking, running and trotting with complete custom mechanism to easily extend the base simulation as per requirements through an intuitive Graphical User Interface (GUI).

This article presents a novel architecture using a hybrid model for developing a Sindhi spellchecker system which has yet not been developed prior to this work. The compound textual forms and glyphs of Sindhi language presents a substantial challenge for developing a Sindhi spellchecker system and generating a similar suggestion list for misspelled words. In order to implement such a system, phonetic-based Sindhi language rules and patterns must be taken into account for increasing the accuracy and efficiency. In this research work, a simple and efficient combinational hybrid system is proposed, using three different algorithms, the Edit Distance algorithm to find the measure of similarity between two Sindhi strings. The phonetic-based SoundEx and ShapeEx algorithms are developed for pattern or glyph matching, generating accurate and an efficient suggestion list for incorrect or misspelled Sindhi words. The proposed system is established with a blend between Phonetic-based SoundEx algorithm and ShapeEx algorithm for pattern or glyph matching, generating accurate and efficient suggestion list for incorrect or misspelled Sindhi words. In this article, a table of phonetically similar-sounding Sindhi characters is presented which are grouped together along with another table containing similar glyph or shape-based character groups. The system has been successfully integrated into a pre-developed Sindhi word processer application. The Sindhi word segmentation methodology and algorithms required for the spellchecker has already been published and so are not discussed in detail in this article.

Character rigging is a process of endowing a character with a set of custom manipulators and controls
making it easy to animate by the animators. These controls consist of simple joints, handles, or even
separate character selection windows.This research paper present an automated rigging system for
quadruped characters with custom controls and manipulators for animation.The full character rigging
mechanism is procedurally driven based on various principles and requirements used by the riggers and
animators. The automation is achieved initially by creating widgets according to the character type. These
widgets then can be customized by the rigger according to the character shape, height and proportion.
Then joint locations for each body parts are calculated and widgets are replaced programmatically.Finally
a complete and fully operational procedurally generated character control rig is created and attached with
the underlying skeletal joints. The functionality and feasibility of the rig was analyzed from various source
of actual character motion and a requirements criterion was met. The final rigged character provides an
efficient and easy to manipulate control rig with no lagging and at high frame rate.

A large number of publications are available for the Optical Character Recognition (OCR). Significant researches, as well as
articles are present for the Latin, Chinese and Japanese scripts. Arabic script is also one of mature script from OCR perspective. The adaptive languages which share Arabic script or its extended characters; still lacking the OCRs for their language. In this paper we present the efforts of researchers on Arabic and its related and adapted languages. This survey is organized in different sections, in which introduction is followed by properties of Sindhi Language. OCR process techniques and methods used by various researchers are presented. The last section is dedicated for future work and conclusion is also discussed.

In this paper we discuss a stand-alone system to allow the deaf or hard-of-hearing people and normal people to communicate with each other easily and fluently. We purpose a model for recognizing Malaysian Sign Language through image processing techniques and converting the visual information into textual information at real-time. In order to implement a real time hand gesture recognition system, video footage will be obtained from digital camera or cellphone camera, then hand position and location will be marked and cropping will be done to isolate them. Then the hand gestures will be recognized through image processing and matched to a prebuilt database of gestures which will be used for textual conversion on the screen. In the final step the normal person will type the text and its equivalent animation of hand gestures will be presented. Through this system, real-time recognition of Malaysian Sign Language and textual representation is done, giving more accurate results at least possible time. It will not only benefit the deaf and dumb people of Malaysia but also could be used in various applications in the technology field. This system provides the flexibility to learn Malaysian Sign Language at personal pace, at anytime and anywhere at home or at workplace.

This research paper present some statistical similarities and dissimilarities between the character frequencies of three languages, Malay, Indonesia and English. The reason for their comparison is that they all share a common symbol set (A-Z). It has been found, through investigations that statistically Malay and Indonesian language character frequencies are very close to each other. For example, character "A" "N" and "E" in both Malay and Indonesian languages have frequencies (19%, 20.4%), (10%, 9.33%) and (9%, 8.28%), respectively. However, the case of English is different, where characters "E", "T" and "A" come with three highest frequency occurring letters, respectively. An interesting observation is that in spite of some similarities and dissimilarities between the characters, all three language follow envelop of the frequencies identically rising and falling trend for all characters. Moreover, for all three languages, last four characters, "W, X, Y, Z", also exhibit lowest usage in their respective languages.

Dictionaries are the fundamental building block of any language facilitating the language learners, scholars, teachers, students and native speakers with vital understanding of linguistics resources. In this paper we discuss the implementation of Unicode based bilingual dictionary in Sindhi to English and English to Sindhi; targeted specifically for children. There doesn’t exists any such type of software system which is specifically for the young school going children of Sindh Province, that would facilitate and aid them in learning English language. This application thus is the first ever attempt to cultivate English to Sindhi and Sindhi to English Pictorial dictionary for Sindhi speaking Children. The system is developed using Java programming language with database managed through Hash-table. The system uses java beans to create and store the dictionary word information as objects and serialized to save it in a file using java’s object serialization technique. Initially a two set of user interfaces are created. First is the administrator section that is used to enter and save words and meanings along with their corresponding picture. The second section is the end user section that is used by the students to search and view the Sindhi-English word with picture. The words included are specifically targeted towards the children of Sindh and contain approximately thirty Three thousand words.

This research paper addresses the problem of generating involuntary and precise animation of quadrupeds with automatic rigging system of various character types. The technique proposed through this research is based on a two tier animation control curve with base simulation being driven through dynamic mathematical model using procedural algorithm and the top layer with a custom user controlled animation provided with intuitive Graphical User Interface (GUI). The character rig is based on forward and inverse kinematics driven through trigonometric based motion equations. The User is provided with various manipulators and attributes to control and handle the locomotion gaits of the characters and choose between various types of simulated motions from walking, running, trotting, ambling and galloping with complete custom controls to easily extend the base simulation as per requirements.
