As an important sensor of unmanned surface vehicle (USV), electro-optical device is usually used to detect ships and obstacles in USV autonomous navigation collision avoidance. However, the installation perpendicularity error greatly impacts line-of-sight (LOS) stability control. This difficult eliminate through mechanical calibration because platform inertial axis cannot be led out. study aims...

The motivation for this paper is the need to detect radial fatigue cracks in a shaft/bearing assembly (as shown in Fig. 1), using guided circumferential waves. To do so, wave propagation in a layered cylinder must be understood. In order to accurately detect the crack, the dispersion relationship for guided circumferential waves must be known; this enables the selective generation of specific w...

The familiar Newtonian version of the Rayleigh criterion demands that for dynamical stability the specific angular momentum should increase with the increasing circumferential radius of circular trajectories of matter. However, sufficiently close to a black hole the Rayleigh criterion reverses: in stable fluids, the angular momentum must decrease with the increasing circumferential radius. The ...

BACKGROUND Fractured neck of femur generally requires operative fixation and is a common cause of admission to hospital. The combination of femoral nerve block and spinal anesthesia is a common anesthetic technique used to facilitate the surgical procedure. The optimal disposition of local anesthetic (LA) relative the femoral nerve (FN) has not been defined. Our hypothesis was: that the deposit...

OBJECTIVES The purpose of this study was to compare the longitudinal, circumferential, and radial mechanics of the left ventricle (LV) in patients with constrictive pericarditis (CP) and restrictive cardiomyopathy (RCM). BACKGROUND Diastolic dysfunction in CP is related to epicardial tethering and pericardial constraint, whereas in RCM it is predominantly characterized by subendocardial dysfu...

We discuss the continual reassessment method (CRM) and its extension with practical applications in phase I and I/II cancer clinical trials. The CRM has been proposed as an alternative design of a traditional cohort design and its essential features are the sequential (continual) selection of a dose level for the next patients based on the dose-toxicity relationship and the updating of the rela...

In addition to the Manak et al. microarray data, we used the microarray data of Stolc et al. (2004) to examine whether or not the REDfly analysis CRMs are transcribed. Among the key differences between these two datasets are that (1) the Manak et al. experiments were done using total RNA while the Stolc et al. experiments used polyA-selected RNA and (2) the Manak et al. microarrays were more fu...
