Writing information onto nanoscale magnetic oscillators as magnetic bits presents many challenges, some of which become more formidable as we pursue higherdensity information storage. It is true that the electric current densities needed at present to rotate the magnetization direction are lower than those needed in traditional semiconductor devices, where information has to be constantly rewri...

It is demonstrated by means of density functional and ab initio quantum chemical calculations, that transition-metal-carbon systems have the potential to enhance the presently available area density of magnetic recording by 3 orders of magnitude. As a model system, Co2 benzene with a diameter of 0.5 nm is investigated. It shows a magnetic anisotropy of the order of 0.1 eV per molecule, large en...

Today’s technology demands compact, portable, fast, and energy-efficient devices. One approach to making devices is an in-memory computation that addresses the memory bottleneck issues of present computing system by utilizing a spintronic device viz. magnetic tunnel junction (MTJ). Further, area energy can be reduced through approximate computation. We circuit design based on logic-in-memory pa...

This paper discusses cake-cutting protocols when the cake is a heterogeneous good, represented by an interval on the real line. We propose a new desirable property, the meta-envy-freeness of cake-cutting, which has not been formally considered before. Meta-envy-free means there is no envy on role assignments, that is, no party wants to exchange his/her role in the protocol with the one of any o...

This paper discusses cake-cutting protocols when the cake is a heterogeneous good that is represented by an interval in the real line. We propose a new desirable property, the meta-envy-freeness of cake-cutting, which has not been formally considered before. Though envy-freeness was considered to be one of the most important desirable properties, envy-freeness does not prevent envy about role a...

The work is devoted to the calculation of main technological parameters a bit new patented design, essence which replace worn out working elements (carbide cutters or diamond-containing matrices) during drilling with new, not blunt tool right at bottom well. need correct method associated design feature crown, consists in fact that when using it, an annular larger width formed compared serial c...

Large strains, anisotropy of mechanical properties of materials and Coulomb friction in contact regions are some properties in the analysis of deep drawing process. In this research, the effects of different parameters such as anisotropy coefficient, work hardening exponent and friction coefficient on deep drawing process of drawing quality steel are studied. For this purpose, the finite elemen...

Binary stochastic neurons (BSNs) are excellent activators for machine learning. An ideal platform implementing them low- or zero-energy-barrier nanomagnets (LBMs) possessing in-plane anisotropy (e.g. circular slightly elliptical disks) whose fluctuating magnetization encodes a probabilistic (p-) bit. Here, we show that such BSN's activation function, the pinning current (which pins output to pa...

We use experiments to explore the effect of surfactants on bubble-induced turbulence (BIT) at different scales, considering how bubbles affect flow kinetic energy, anisotropy and extreme events. To this end, high-resolution particle shadow velocimetry measurements are carried out in a bubble column which is generated by swarms rising water for two diameters (3 4 mm) moderate gas volume fraction...

Quantitative analysis of cutting removal used in this study uses three methods, namely Cutting Carry Index, Transport Ratio, and Concentration Annulus. This method is to determine whether the composition mud maximal or not, starting from maximum content solids that can be carried 1 gal viscosity also flow pattern fluid order successfully bring surface. Where these methods have standardization l...
