Metris is a version of the Tetris game that uses a player’s musical response to control game performance. The game is driven by two factors: traditional game design and the player’s individual sense of music and sound. Metris uses tuning principles to determine relationships between pitch and the timbre of the sounds produced. These relationships are represented as bells synchronised with signi...

This paper considers the Greenspan/Summers/IMF (GSI) argument that the Asian way of doing business was the deep cause of the Asian crisis. The IMF reform programme for the crisis-affected Asian countries suggested they should abandon the Asian business model and adopt the US corporate model. The main findings are: a) contrary to GSI doctrine, poor corporate governance and lack of competition ar...

Color preference research has traditionally focused on summarising or explaining the color preferences of groups of people. Claims of universal patterns and trends in color preference have generally been based on group analyses, with little consideration of the individual. Initial investigation of this issue has revealed that, although patterns can be identified at the group level, individual d...

To a given nonsingular triangular matrix A with entries from a ring, we associate a weighted bipartite graph G(A) and give a combinatorial description of the inverse of A by employing paths in G(A). Under a certain condition, nonsingular triangular matrices A such that A and A−1 have the same zero-nonzero pattern are characterized. A combinatorial construction is given to construct outer invers...

⎯By employing the Lyapunov stability theory and linear matrix inequality (LMI) technique, delaydependent stability criterion is derived to ensure the exponential stability of bi-directional associative memory (BAM) neural networks with time-varying delays. The proposed condition can be checked easily by LMI control toolbox in Matlab. A numerical example is given to demonstrate the effectiveness...

A transition effect matrix (TEM) is a quantum generalization of a classical stochastic matrix. By employing a TEM we obtain a quantum generalization of a classical Markov chain. We first discuss state and operator dynamics for a quantum Markov chain. We then consider various types of TEMs and vector states. In particular, we study invariant, equilibrium and singular vector states and investigat...

This paper studies impulsive control systems with finite and infinite delays. Several stability criteria are established by employing the largest and smallest eigenvalue of matrix. Our sufficient conditions are less restrictive than the ones in the earlier literature. Moreover, it is shown that by using impulsive control, the delay systems can be stabilized even if it contains no stable matrix....

In this paper, the stability analysis and control design of Takagi–Sugeno (TS) fuzzy systems subject to uncertain time-delay are addressed. The proposed approach is based on linear matrix inequalities and the Lyapunov–Krasovskii theory, where a new fuzzy weighting-dependent Lyapunov–Krasovskii functional is introduced. By employing the Gu discretization technique and strategies to add slack mat...

In this research, the effect of different biopolymers such as polyethylene glycol (PEG) and polyvinylalcohol (PVA) on synthesis and characterization of polymer/cobalt ferrite (CF) nano-composites bymechanical alloying method has been systematically investigated. The structural, morphological andmagnetic properties changes during mechanical milling were investigated by X-ray diffraction (XRD),Fo...

We prove an analogue of Alon's spectral gap conjecture for random bipartite, biregular graphs. use the Ihara-Bass formula to connect non-backtracking spectrum that adjacency matrix, employing moment method show there exists a matrix. A byproduct our main theorem is rectangular zero-one matrices with fixed row and column sums are full-rank high probability. Finally, we illustrate applications co...
