Experiments were done on the skin with shearing forces, vibrations, and heat stimuli and on the tongue with taste stimuli to show that the well known Mach bands are not exclusively a visual phenomenon. On the contrary, it is not difficult to produce areas of a decreased sensation magnitude corresponding to the dark Mach bands in vision. It is shown on a geometrical model of nervous interaction ...

Mach is a multiprocessor multithreaded operating system. This implies that several threads try to access and modify the same data at the same time. It is necessary to avoid consistency problems without performance bottlenecks. In this paper we describe the use of coordination techniques when accessing some of the data structures used in the Mach Kernel to represent the different abstractions. T...

The Mach 3.0 I/O system represents a radical departure from its predecessor { Mach 2.5, which relied on the BSD Unix model of device management. The I/O interface in Mach 3.0 supports device drivers that are largely device-independent, implemented at user-level, and location-independent. Our approach to device management signiicantly reduces the size of the kernel's machine-dependent code, enab...

A perfectly expanded turbulent Mach 1.92 jet was simulated by direct numerical solution of the compressible Navier-Stokes equations in a computational domain that included the near acoustic eld. Reynolds stresses, two-point correlations, and turbulent energy spectra are computed and discussed. The sound eld is highly directional and dominated by Mach waves as are commonly observed experimentall...

Direct numerical simulations (DNS) are carried out to investigate the effect of effu-sion cooling by blowing through spanwise slits and discrete holes in a laminar flat-plate boundary layer at various Mach numbers. The comparison with experimental data for a Mach-2.67 boundary layer with a cool wall and a spanwise slit shows good agreement. For an adiabatic Mach-6 boundary layer, the focus of t...

The current study investigates the associations of Machiavellianism (Mach) with trait and ability emotional intelligence (EI), and theory of mind (ToM) in 109 primary school children. Consistent with previous research with adults, negative associations were found between Mach and social and emotional understanding. Subsequent multiple regression analyses for girls showed that being more adept a...

Most of the materials used in the industry of aero-engine components generally consist of titanium alloys. Advanced materials, because of their excellent combination of high specific strength, light weight and general corrosion resistance. In fact, chemical wear resistance of aero-engine alloy provides a serious challenge for cutting tool material during the machining process. The reduction in ...
