The robust stabilization of roll angle for PGM-class missiles (precision guided missiles) is considered in this paper. The roll dynamics in these missiles are stable but have large parametric variations and slow response behavior. A novel method for

Transfer alignment is the process of initializing the navigation sensors of tactical guided munitions launched from a platform. Through this method the misalignment between aligning and aligned body is estimated, which facilitates navigation of align

Ferrite grain sizes of the order of 1 to 2 µm were obtained by optimizing the strain, strain rate, the stage of cooling, as well as the cooling rate during hot rolling of 0.15C-0.92Mn-0.01Si-0.036S-0.04P-0.013Nb steel. It was found that in single-pa

Methanolic extracts of eight subspecies of genus Argyranthemum were evaluated against brine shrimps, human cancer cell lines, malarial parasites and microorganisms under in vitro conditions. In the shrimp assay, samples of A. adauctum ssp. adauctum,

Ten different samples of five Hypericum sp. were tested on brine shrimps, human colon carcinoma and human hepatoma cell lines for their cytotoxic activities. H. triquetrifolium Turra. (Rafina) showed the highest activity (LC50 = 22 mg/mL) on brine sh

Quenching induced orthorhombic distortion makes quenched (Q) lead meta-niobate (PbNb2O6), to be called PNQ, piezoelectric with a high Curie temperature (Tc) of 570 °C, while its slow-cooled rhombohedral phase, PNS, remains non-piezoelectric. So, pos

Small addition of titanium (∼0·01 wt-%) to low carbon (∼0·04 wt-%) aluminium killed extra deep drawing quality steel resulted in a decrease in strain aging as well as a decrease in plastic anisotropy after cold rolling and annealing. The extent

Various processing parameters leading to edge cracking in hot-rolled coils are described, along with a study of the effect of these parameters on the occurrence of edge cracking during commercial production of semi-killed hot-rolled coils. High-tempe

The purpose of the guidance law is to determine appropriate missile flight path dynamics to achieve mission objective in an efficient manner based on navigation information. Today, guided missiles which are aerodynamically unstable or non-linear in a

The robust stabilization of roll angle is considered in this paper. The roll dynamics is stable but it has large parametric variations and slow response behaviour. Here, a new method for sliding mode control is presented to robustly stabilize the rol
