Daou et. al. have synthesized Fe3O4 nanoparticles of size 39 nm±5 nm by hydrothermal reaction of 1 M ferric chloride hexa-hydrate (FeCl3. 6H2O) and 2 M ferric chloride tetra hydrate (FeCl2. 4H2O) dissolved in 2 M HCl followed by slow addition of aqueous solution of tetramethyl ammonium hydroxide [N(CH3)4OH] [15].
Mascolo et.al., Fe3O4 nanoparticles (63 nm±25nm) were synthesized by coprecipitation method in alkaline condition using FeCl3 and FeCl2 salts [16].

The predictive functional control (PFC) developed by Richalet et al. [2, 3, 4] is a kind of the model predictive control (MPC) schemes.
To overcome this drawback, Satoh et al. [5, 6] proposed a PFC using the disturbance observer [8] (DOB-PFC) where the inner disturbance observer velocity feedback loop cancels disturbances immediately and the outer PFC position feedback loop achieves good reference tracking.
According to the numerical design procedure used in Satoh et al. [5], we obtained the following second-order binomial filter with a cut-off frequency of 45 Hz: (23) The designed Q-filter is implemented as a digital filter in the actual control system for the one-axis table drive system.

Kahtan et al [11], Johnson and German [12] and Boonyonmaneerat [13] showed that the addition of transitional metals like Co, Fe, Ni and Pd can significantly enhance the sintering kinetics of these composites and reduce their sintering temperatures.
The phenomenon of lower densification might be as a result of inadequate sintering temperatures and immiscibility between W and brass.Adestani et al [19] worked on the effects of sintering temperature on densification of nano scale dispersed W-20-40 wt.
Ozkal et al [20] while working on real-time sintering observation in W-Cu system discovered that, prior to Cu melt formation, none of the compact shows appreciable densification, but at the onset of melt formation, both compacts were densified.
