This paper introduces a novel means of representing ternary states using color-codes, suggests a logic design model for a ternary half adder circuit and separate carry circuits. A ternary simulator was also developed to aid in the research and development of ternary systems.

This paper presents rhotrix multiplication and introduces its implementation on process grid topologies. Covered in this work, are reviews of generalization cases of n-dimensional rhotrix multiplication. A parallel program based on MPI master-worker paradigm is implemented. By means of analyzing the time complexity and memory requirement for the method, the authors provided insight into how to fully utilize the algorithm for heart-oriented rhotrix multiplication in anticipation of establishing a standard for parallel rhotrix multiplication and to speed up its multiplication based on existing HPC tools.

This paper identifies the causes associated with delays in processing and releasing results in tertiary institutions. An enhanced computer program for result computation integrated with a database for storage of processed results simplifies a university grading system and overcomes the short-comings of existing packages. The system takes interdepartmental collaboration and alliances into consideration, over a network that speeds up collection of processed results from designated departments through an improved centralized database system. An empirical evaluation of the system shows that it expedites processing of results and transcripts at various levels and management of and access to student results on-line. The technological approach for the implementation of the proposed system is based on open source solutions. Apache is used as Web server extended with PHP for server side processing. In recognition of the confidentiality of data contained in the system, communication networks are protected with open-ssl library for data encryption and role-based authentication. This system increases efficient service delivery and benefits both administration and students.

This paper introduces a novel generalized concept of higher order heart-oriented rhotrix multiplication expression. The multiplication method we adapted is intended to maintain the unique properties associated with the initial definition of rhotrix. The special multiplication process can be used to solve various problems involving n x n rhotrices multiplication. Most importantly a generalized expression for representing n-dimensional rhotrix in a computational environment is presented. Sequential computational algorithm for higher order rhotrices multiplication is designed to buttress the mathematical expression, axioms and logic presented in this paper.. General Terms

The paper presents a generic reference architecture framework for collaboratory experiment virtual laboratory. The model presented is open source driven, flexible and based on modern tools and technologies. This in effect will allow geographically remote scientists with limited internal laboratory resources, access to wealth of experimental datasets, computing facilities, and distributed hard-to-duplicate laboratory devices. The key issues discussed are architectural design and choice of technology used for creating virtual laboratory. This architecture offers great levels of flexibility, simplicity, and interoperability that are needed to allow integration between heterogeneous distributed grid resources and its clients and executors. The framework, besides theoretical modelling, will provide a road map for future research and open questions.
