In order to satisfy the rising energy demands of global consumption, a new cleaner and renewable power source needs to be explored, conceptualized and developed. This paper intends to introduce an alternative source of energy by using piezoelectric material -a class of smart material. A piezoelectric road that will produce electricity from the stress experienced by the roads due to the movement...

In this group thesis, we develop an algorithm that allows the automated classification of resistors using image recognition. The algorithm is implemented in an Android app and therefore usable on every Android smartphone. The problem is split into parts and the result is obtained step by step beginning with the localization of the resistor in the captured image and cropping the image such that ...

Background/Aims Currently, there exists no biomarker for visceral hypersensitivity in irritable bowel syndrome (IBS). Piezo proteins have been proven to play an important role in the mechanical stimulation to induce visceral pain in other tissues and may also be a biomarker candidate. The aim of this study was to test the expressions of Piezo1 and Piezo2 proteins in the intestinal epithelial ce...

An approach of Green’s function is adopted to solve the inhomogeneous linear differential equations representing wave equations in piezo-composite materials. In particular, transference of horizontally polarised shear (SH) waves is considered in bedded structure comprising of porous-piezo electric layer lying over a heterogeneous half-space. Propagation of SH-waves is considered to be influence...

Can we change the average state of a resistor by simply applying white noise? We show that the answer to this question is positive if the resistor has memory of its past dynamics (a memristive system). We also prove that, if the memory arises only from the charge flowing through the resistor-an ideal memristor-then the current flowing through such memristor cannot charge a capacitor connected i...

Conductance fluctuations in hydrogenated amorphous silicon (a-Si:H) are simulated using a dynamical model of resistor diffusion on a lattice held at the percolation threshold. A fraction of lattice sites is designated as a trap, such that when a resistor diffuses onto that site it remains localized for a finite period of time. When a distribution of traps based on the defect density of a-Si:H i...

In a recent paper [1], Giannetti considered the thermal noise generated by a resistor R on a generic output port in any linear network. He reasoned that, because the contribution of the thermal noise of the resistor to the output noise of the circuit vanishes for both R! 0 and R ! 1, there should be a resistor value whose contribution to the output noise is maximal. In order to find that value,...

The inrush current is a transient current that results from a sudden change in the exciting voltage across a transformer’s windings. It may cause inadvertent operation of the protective relay system and necessitate strengthening of the transformer’s mechanical structure. Many methods were reported in the literatures for reduction and mitigation of transformer inrush currents. This paper represe...

In this study, a novel floating frequency dependent negative resistor (FDNR), floating inductor, floating capacitor and floating resistor simulator circuit employing two CBTAs and three passive components is proposed. The presented circuit can realize floating FDNR, inductor, capacitor or resistor depending on the passive component selection. Since the passive elements are all grounded, this ci...
