Beyond Complex Numbers

There has been always an ambiguity in division when zero is present in the denominator. So far this ambiguity has been neglected by assuming that division by zero as a non-allowed operation. In this paper, I have derived the new set of numbers by considering that a number divided by zero gives rise to "a beyond complex number". This is very similar to the way imaginary numbers are defined. It was only after considering i = sqrt(-1), we have been able to deduce all the laws for imaginary numbers. Similarly here, I have considered "a number when divided by zero gives rise to a beyond complex number". This is the introduction paper to this "beyond complex numbers" containing the algebra of it.

An Alternate Graphical Representation of Periodic table of Chemical Elements

Periodic table of chemical elements symbolizes an elegant graphical representation of symmetry at atomic level and provides an overview on arrangement of electrons. It started merely as tabular representation of chemical elements, later got strengthened with quantum mechanical description of atomic structure and recent studies have revealed that periodic table can be formulated using SO(4,2)* SU(2) group. IUPAC, the governing body in Chemistry, doesn't approve any periodic table as a standard periodic table. The only specific recommendation provided by IUPAC is that the periodic table should follow the 1 to 18 group numbering. In this technical paper, we describe a new graphical representation of periodic table, referred as 'Circular form of Periodic table'. The advantages of circular form of periodic table over other representations are discussed along with a brief discussion on history of periodic tables.

Frequency Analysis of Decoupling Capacitors for Three Voltage Supplies in SoC

Reduction in power consumption has become a major criterion of design in modern ICs. One such scheme to reduce power consumption by an IC is the use of multiple power supplies for critical and non-critical paths. To maintain the impedance of a power distribution system below a specified level, multiple decoupling capacitors are placed at different levels of power grid hierarchy. This paper describes about three-voltage supply power distribution systems. The noise at one power supply can propagate to the other power supply, causing power and signal integrity problems in the overall system. Effects such as anti-resonance and remedies for these effects are studied. Impedance of the three-voltage supply power distribution system is calculated in terms of RLC-model of decoupling capacitors. Further the obtained impedance depends on the frequency; hence brief frequency analysis of impedance is done.

On Dimensional Analysis, Redundancy in set of fundamental quantities and Proposal of a New Set

Inclusion of redundant fundamental quantities in SI system has resulted in lot of ambiguities and confusion in modern theories. The incompatibilities between the existing theories can possibly be due to incorrect assumption of fundamental quantities and existence of newer fundamental quantities. This paper is an attempt to eliminate the redundancy in the SI system using random mathematical mappings done through a computer program on SI system to New System. Each mathematical mapping is studied manually. Out of 1000 random mathematical mappings generated using a Computer Program, a mapping with three fundamental quantities is found to describe a non-redundant and intuitive set of Fundamental quantities. This paper also proposes the possible existence of a new fundamental quantity. A significant attempt is made to understand the advantages of new system over SI system. The relations between the set {Mass, length, time, current, and temperature} and new set of three fundamental quantities are calculated. The paper also describes the intuitive reasons favoring the new fundamental set of quantities.

Architecture for Pseudo Acausal Evolvable Embedded Systems

Advances in semiconductor technology are contributing to the increasing complexity in the design of embedded systems. Architectures with novel techniques such as evolvable nature and autonomous behavior have engrossed lot of attention. This paper demonstrates conceptually evolvable embedded systems can be characterized basing on acausal nature. It is noted that in acausal systems, future input needs to be known, here we make a mechanism such that the system predicts the future inputs and exhibits pseudo acausal nature. An embedded system that uses theoretical framework of acausality is proposed. Our method aims at a novel architecture that features the hardware evolability and autonomous behavior alongside pseudo acausality. Various aspects of this architecture are discussed in detail along with the limitations.

Novel Technique for Volatile Optical Memory Using Solitons

Recent advances in optics have shown that solitons have a great potential for upgrading the future optical systems which demand fast and reliable data transfer. Along side Different architectures have evolved to realize an optical computer. Due to difference in processing speeds of optical and electronic devices and usage of opto-electronic converters the efficiency of the optical computers is affected. In this paper we bring a novel technique for volatile optical memory using solitons which would be part of realizing an optical computer. Also the principle of read and write operations in the soliton based volatile memory systems is shown.
