In this paper a full order observer has been designed using generalized matrix inverse. The design method resolves the state vector into two unique components, of which one is known and the other is unknown. This method does not assume any structure of the observer and imposes no restriction on the output distribution matrix. Condition of existence of such observer is presented with proof. An i...

AIM To observe the neurological complications arising from various tribal practices and their management. Penetrating head injuries comprise only a small number of total head injuries. A penetrating head injury by deliberate attempt to treat an ailment is almost unheard of. MATERIAL AND METHODS We present here a case of penetrating head injury caused by stabbing a scissor in head by a local w...

A new nonlinear sliding mode, which can be expended and used in a large family nonlinear systems , is skillfully constructed for supersonic missile control with unknown control direction. Later, by using of the Nussbaum gain method, the unknown control direction problem is solved and also the appearance of control singularity was avoided. So the nonlinear sliding mode method and Nussbaum gain m...

In this study, the missile staging process by implementing a side-injected jet is simulated numerically. The problem is considered to be axisymmetric and the thin shear layer approximation of Navier-Stokes equations along with an algebraic turbulence model is used in a quasi-static form for the calculations. The free stream corresponds to a very high altitude flight condition with a Mach number...

Hypersonic missiles represent the new class of threats, capable declaratively and in a way that has not been proven theater operations, to annihilate air anti-missile defences exist at this time. The sum threat’s characteristics, high speed, increased maneuverability, low flight altitude, get major concerns for missile defence, as effective detection combat are reduced by compressing available ...

Collagen 1 promotes epithelial-to-mesenchymal transition in lung cancer cells via transforming growth factor-b signalling. Inflammatory markers are associated with ventilatory limitation and muscle dysfunction in obstructive lung disease in well functioning elderly subjects. Usefulness of C-reactive protein and interleukin-6 as predictors of outcomes in chronic obstructive pulmonary disease rec...

phenytoin (pht), a drug in clinical use for over fifty years as an anticonvulsant, has heen reported to promote the healing of skin and soft tissue wounds, ulcers and second degree burns. we treated 19 patients with war-related missile wounds and 6 with chronic, non-healing (previously treated at least for.') months with antibiotics and betadine or acetic acid dressing) civilian ulcers wit...

A capture region for missile guidance laws under field-of-view constraint is analyzed. To make a missile intercept a non-maneuvering target, physical constraints including seeker`s field-of-view and acceleration limit should be considered, because these constraints may restrict maneuver of the interceptor. The characteristics of look-angle constraint guidance laws is studied, and feasible traje...

The PRC’s surface-to-surface missile forces would be a major factor in an invasion scenario, such as the one we assess in the main body of this report. China’s missiles would also be at the heart of many other coercive strategies aimed at Taiwan, ranging from the kinds of exercises held in 1995 and 1996 to actual employment against military, political, and economic targets in an attempt to use ...
