Almost all existing node selection algorithms of the underwater sensor networks (USNs) are designed by assuming ideal environments. However, position floating nodes which caused ocean currents cannot be ignored in practice. Aiming at solving this problem during target tracking, a algorithm based on multi-objective optimization under was proposed paper. First, error is converted into noise. Then...

Multiple results in the literature exist that indicate that all computed solutions to chaotic dynamical systems are time-step dependent. That is, solutions with small but different time steps will decouple from each other after a certain (small) finite amount of simulation time. When using double precision floating point arithmetic time step independent solutions have been impossible to compute...

PURPOSE The purpose of this study was to develop an algorithm based on region-based segmentation for automated calculations of human cone photoreceptor density of en face images obtained by an adaptive optics scanning laser ophthalmoscope (AOSLO). SUBJECTS AND METHODS Cone mosaics of 15 eyes of 15 healthy subjects were photographed by a custom-built AOSLO. The cone density was calculated at 0...

An oral sustained-release floating tablet formulation of metformin HCl was designed and developed. Effervescence and swelling properties were attributed on the developed tablets by sodium bicarbonate and HPMC-PEO polymer combination, respectively. Tablet composition was optimized by response surface methodology (RSM). Seventeen (17) trial formulations were analyzed according to Box-Behnken desi...

Floating ring seals are widely used as a leakage control solution for turbomachines because they effectively operate with small clearances between the shaft and seal. The oxidizer pump of 7 tonf liquid engine in Korea Space Launch Vehicle II (KSLV-II) operates at high rotational speeds under cryogenic conditions has floating bearing cooling path to reduce leakages. In this study, we evaluated f...

This paper introduces a design and fabrication pipeline for creating floating forms. Our method optimizes for buoyant equilibrium and stability of complex 3D shapes, applying a voxel-carving technique to control the mass distribution. The resulting objects achieve a desired floating pose defined by a user-specified waterline height and orientation. In order to enlarge the feasible design space,...

The verification of programs performing floating-point computations is a key issue in the development of critical software. Reasoning on floatingpoint computations is a tricky task that requires dedicated tools: floatingpoint arithmetic is not correctly handled by solvers over the reals. Several methods have been developed in order to verify programs working with floating-point numbers. Some of...

High speed execution of arithmetic operations and high degree of precision in real time system are of major concern in any digital signal processing (DSP). Speed of DSP depends on speed of multiplier and algorithm used. In this paper we propose Residue Number System method for fast “carry free” floating point arithmetic operations. Floating Point RNS units have obvious advantages over tradition...
