This paper presents an approach for the swing up and stabilization of a rotary inverted pendulum (RIP). RIP system is an unstable, multi-variable, under actuated and highly nonlinear in nature. RIP consists of a pivot arm, the pivot arm rotates in a horizontal plane by means of a servo motor. The opposite end of the arm is attached to the pendulum rod whose axis is along the radial direction of...

We consider the problem of constructing a linear map from a Hilbert space H (possibly infinite dimensional) to R that satisfies a restricted isometry property (RIP) on an arbitrary signal model S ⊂ H. We present a generic framework that handles a large class of low-dimensional subsets but also unstructured and structured linear maps. We provide a simple recipe to prove that a random linear map ...

Photoreceptor cell death is the terminal event in a variety of retinal disorders including age-related macular degeneration, retinitis pigmentosa, and retinal detachment. Apoptosis has been thought to be the major form of cell death in these diseases, however accumulating evidence suggests that another pathway, programmed necrosis is also important. Recent studies have shown that, when caspase ...

Fourier transform spectroscopy and interference microscopy are combined to provide the world's first multi-wavelength optical fiber refractive index profile (RIP) measurements. The RIP and its spectral dependence are obtained with submicron spatial resolution across an octave stretching from about 500 nm to the 1 micron operating band of Yb-doped fiber lasers and amplifiers. In contrast to comm...

The generation of nuclear signaling proteins by regulated intramembrane proteolysis (RIP) is a new paradigm of signal transduction. Mammalian proteins that are processed by RIP include SREBP-1, Notch-1, amyloid precursor protein (APP), and ErbB-4. Intramembranous gamma-secretase cleavage of APP plays a central role in Alzheimer's disease by generating the amyloid beta protein. An intriguing pos...

The essence of the preconditioning effect is activation urgent defense mechanisms adaptation as a result short episode weak, non-damaging hypoxic or ischemic exposure, which contributes to an increase in tolerance subsequent delayed, more severe exposure hypoxia ischemia. Aim study was assess literature data on possibility using method remote (RIP) non-pharmacological for correcting physical per...

According to a popular quip, fittingly though incorrectly attributed to the great dyspeptic metaphysicist Arthur Schopenhauer, all truth passes through three stages: first, it is ridiculed; second, it is violently opposed; third, it is accepted as self-evident (1). In the iconoclastic world of biomedical research, however, that is so eager to challenge the old and propose novel paradigms, the e...

We examine nonrelativistic particles that decay into relativistic products in big rip, little and pseudorip models for the future evolution of Universe. In contrast to decays occur standard $\mathrm{\ensuremath{\Lambda}}\mathrm{CDM}$, ratio $r$ energy density initially decaying can decrease with time all these models. rip models, always goes zero asymptotically, while this evolves infinity or a...

Compressive Sampling (CS) describes a method for reconstructing high-dimensional sparse signals from a small number of linear measurements. Fundamental to the success of CS is the existence of special measurement matrices which satisfy the so-called Restricted Isometry Property (RIP). In essence, a matrix satisfying RIP is such that the lengths of all sufficiently sparse vectors are approximate...

BACKGROUND We are reporting a case of granulomatous panuveitis in the right eye following penetrating injury to the left eye. FINDINGS A 34-year-old female was diagnosed to have sympathetic ophthalmia on treatment with systemic steroids. Vision did not improve in spite of aggressive systemic steroid therapy. On examination, patient had large retinal pigment epithelial rip nasal to the disc wi...
