As it is well known, symmetry plays a crucial role in the theoretical physics. On other hand, the Noether symmetry is a useful procedure to select models motivated at a fundamental level, and to discover the exact solution to the given lagrangian. In this work, Noether symmetry in f(T) theory on a spatially homogeneous and anisotropic Bianchi type I universe is considered. We discuss the Lagran...

In this design study, we introduce a novel class of digital audio effects that extend the recently introduced modal processor approach to artificial reverberation and effects processing. These pitch and distortion processing effects mimic the design and sonics of a classic additive-synthesis-based electromechanical musical instrument, the Hammond tonewheel organ. As a reverb effect, the modal p...

BACKGROUND: For the cultivation of agricultural crops, technology basic dump tillage is widely used. More than 40% energy resources are spent on it, due to traction resistance working bodies general-purpose plows. The technological process plowing with such has not changed much historically. Pruning soil layer carried out a ploughshare, crumbling and turning blade, stability movement body provi...

This paper discusses the circuit theory aspects of power factor correction in switching converter circuits. The discussion begins with an examination of the requirement of power factor correction in dc=dc converters. Using the concept of zero-order converter circuits, su cient conditions for a dc=dc converter circuit to provide power factor correction are derived. The duality principle is appli...

Designing a low power clock network in synchronous circuits is an important task. This requirement is stricter for 3-D circuits due to the increased power densities. Resonant clock networks are considered efficient low-power alternatives to conventional clock distribution schemes. These networks utilize additional inductive circuits to reduce the power consumption while delivering a full swing ...

We consider power control methods for two-way amplify-and-forward (AF) relay systems. Traffics with different quality-of-service (QoS) requirements are exchanged between two transmit nodes where one of the traffics is a rate-constrained (RC) traffic and the other is a best-effort (BE) traffic. Based on the QoS feasibility of RC traffic, we propose two types of power control methods to maximize ...

India seeks to achieve 175 Giga-Watt (GW) of Renewable power by 2022. As of December 2017, out of 333 GW of total installed capacity of electricity, close to 62GW come from renewable sources. Meeting the set targets calls for augmentation of renewable energy based capacities as expeditiously as possible. However, the sick financial health of the distribution companies/utilities, who act a...
