This paper presents a flexible, low-cost, and ultra-low-energy acoustic sensor network solution. enables both highly distributed real-time audio measurements to be employed in wide variety of scenarios. These types can useful environmental monitoring, healthcare settings, smart cities, security surveillance systems. However, they are typically inflexible their applications require specialized d...

As software systems become larger and more decentralized, increasingly cross organizational boundaries and continue to change, traditional structural and prescriptive software architectures are becoming more rulecentric for better accommodating changes and regulating distributed design and development processes. This is particularly true for Ultra-Large-Scale (ULS) systems and industry-wide ref...

A power system is a nonlinear one. When turbulence occurs in the power system, the stability of the system depends on the initial operating conditions and the nature of the turbulence. Nowadays renewable energy sources including photovoltaic have a key role to meet high demand of modern societies and to maintain voltage of the buses, while they also provide clean electrical energy. However, inc...

The observed CMBR dipole, generally interpreted as the consequence of the peculiar motion of the Sun with respect to the reference frame of the CMBR, can also be explained by the presence of ultra large scale (of the order of 100H 0 ) isocurvature perturbations. Moreover, the simplest model of inflation with several scalar fields, namely that of double inflation, with appropriate parameters, ca...

Numerical aspects are investigated in ultra-large-scale electronic structure calculations. Accuracy control methods in process (molecular-dynamics) calculations are focused upon. Flexible control methods are proposed so as to control variational freedoms, automatically at each time step, within the framework of generalized Wannier state theory. The method is demonstrated in a silicon cleavage s...

Nowadays electronic structure theory gives a microscopic foundation of material science and provides atomistic simulations in which electrons are treated as wavefunction within quantum mechanics. An example is given in the upper left panel of Fig.1. For years, we have developed fundamental theory and program code for large-scale electronic structure calculations, particularly, for nano material...
