Manipulative Aspects of Music

Every sensory stimulus, be it visual, audio, or some other, generates a brain response in the area of the cortex where such information is received, and processed, and gives full meaning or perception of the experience. The cerebral reaction can be monitored by measuring cortical activity through the synchronized response of a large number of neurons, ie. the formed electric wave. EEG scans show that the waves of the brain response in the alpha and beta bands are synchronized around the carrier rhythm of the music track. The sinusoids of the brain waves move in phases so that the peak of the wave always occurs at a precisely defined interval at the point preceding the next beat in the rhythm of the drum. In this way, the rhythm actually synchronizes the brain waves. For centuries, people have used binaural rhythms at 4.5 beats per second and thus causing various mental states. Although unaware of binaural rhythms, shamans were unmistakably known to cause shamanic trance, playing the drum about 4 to 7 beats per second for 13 to 15 minutes. They knew how to recognize the power and positive effects of binaural stimuli. This paper is an attempt to shed light on some possibilities of the manipulative capacities of the phenomenon called music

Contribution to the investigation of the influence of tire non-uniformity on the lateral tire characteristics

Tire models are widely used in research in the field of vehicle dynamics and noise, and especially in the simulation of their movement under the action of forces and moments. In general case, we distinguish theoretical models defined on the basis of tire construction and empirical or semi-empirical models based on experimental tests. In addition, a combination of these two types of models can also produce tire models. In practice, there is a very wide range of mathematical tire models defined using finite element analysis, by approximation of polynomials of different degrees, by approximation of magic formula, etc. In this paper, an attempt is made to calculate non-stationary lateral characteristics of tires on the basis of experimental stationary lateral characteristics, using two-parameter higher level polynomials. This polynomials define the tire lateral characteristics, and take into account their non-uniformity. More specifically, the lateral characteristics are approximated as a function of the dynamic change of the slip angle, radial load due to tire non-uniformity and time

Shot Noise of Spin-Decohering Transport in Spin-Orbit Coupled Nanostructures

We generalize the scattering theory of quantum shot noise to include the full spin-density matrix of electrons injected from a spin-filtering or ferromagnetic electrode into a quantum-coherent nanostructure governed by various spin-dependent interactions. This formalism yields the spin-resolved shot noise power for different experimental measurement setups--with ferromagnetic source and ferromagnetic or normal drain electrodes--whose evaluation for the diffusive multichannel quantum wires with the Rashba (SO) spin-orbit coupling shows how spin decoherence and dephasing lead to substantial enhancement of charge current fluctuations (characterized by Fano factors $> 1/3$). However, these processes and the corresponding shot noise increase are suppressed in narrow wires, so that charge transport experiments measuring the Fano factor $F_{\uparrow \to \uparrow \downarrow}$ in a ferromagnet/SO-coupled-wire/paramagnet setup also quantify the degree of phase-coherence of transported spin--we predict a one-to-one correspondence between the magnitude of the spin polarization vector and $F_{\uparrow \to \uparrow \downarrow}$.Comment: 8 pages, 3 figure; enhanced with 2 new figure

The possibility of traffic accident reconstruction using event data Recorders: A review

Uređaji za beleženje podataka koriste se u svrhu istraga saobraćajnih nesreća više od 20 godina. Neke zemlje su zakonski regulisale njihovu primenu i validan su dokaz u istragama i rekonstrukcijama. Međutim, uređaji za beleženje se koriste kao izvor informacija, a ne kao baza podataka na osnovu kojih je moguće rekonstruisati događaj. Istraživanja samo pomoću uređaja za beleženje još uvek nisu moguća zbog određenih pojava, kao i zbog konstruktivnih karakteristika uređaja. Naučnici iz Japana i Poljske testirali su tačnost podataka iz uređaja i na osnovu njih izvršili rekonstrukcije udesa. Oba tima su utvrdila da je rekonstrukciju moguće izvesti samo u jednostavnim situacijama, poput pravolinijskog udara jednog vozila u drugo. Kada je u udaru više učesnika, ili je udaru prethodio neki manevar, nije moguće utvrditi šta se zaista dogodilo. Neophodan je dalji razvoj ovih uređaja, kako bi se povećala njihova efikasnost prilikom rekonstrukcije saobraćajnih nezgoda.Event Data Recorders (EDRs) have been used for the purpose of investigating traffic accidents for more than 20 years. Some countries have regulated their application by law, and they are a valid evidence during investigations and reconstructions. However, recording devices are used as a source of information, not as a database from which it is possible to reconstruct the event. Investigations using only recording devices are still not possible due to the some phenomena that exist, and due to the constructional features of the devices. Scientists from Japan and Poland tested the accuracy of the data from the devices and performed reconstructions of accidents. Both teams have established that it is possible to perform reconstruction only in simple situations, such as a straight-line crash of one vehicle into another. When there are several participants in a crash, or a crash was preceded by a maneuver, it is not possible to determine what really happened. Further development of data recording devices is necessary, in order to increase their efficiency during the reconstruction of traffic accidents

New possibilities of power electronic structures using SiC technology

This paper is dedicated to the recent unprecedented boom of SiC electronic technology. The contribution deals with brief survey of those properties. In particular, the differences (both good and bad) between SiC electronics technology and well-known silicon VLSI technology are highlighted. Projected performance benefits of SiC electronics are given for several large-scale applications on the end of the contribution. The basic properties of SiC material have been discussed already on the beginning of 80’s, also at our university [1]

Comment on "Spatial optical solitons in highly nonlocal media" and related papers

In a recent paper [A. Alberucci, C. Jisha, N. Smyth, and G. Assanto, Phys. Rev. A 91, 013841 (2015)], Alberucci et al. have studied the propagation of bright spatial solitary waves in highly nonlocal media. We find that the main results in that and related papers, concerning soliton shape and dynamics, based on the accessible soliton (AS) approximation, are incorrect; the correct results have already been published by others. These and other inconsistencies in the paper follow from the problems in applying the AS approximation in earlier papers by the group that propagated to the later papers. The accessible soliton theory cannot describe accurately the features and dynamics of solitons in highly nonlocal media.Comment: 2 page
