Oil entrapped floating alginate beads of curcumin were developed and characterized. Cremophor EL, Cremophor RH and Tween 80 were utilized to improve the solubility of the drug. The oil-loaded floating gel beads prepared by emulsion gelation method contained sodium alginate, mineral oil and surfactant. The drug content and % encapsulation declined as the ratio of surfactant was increased. The re...

Programs with floating-point computations are often derived from mathematical models or designed with the semantics of the real numbers in mind. However, for a given input, the computed path with floating-point numbers may differ from the path corresponding to the same computation with real numbers. A common practice when validating such programs consists in estimating the accuracy of floating-...

The IEEE-754 floating-point standard, used in nearly all floating-point applications, is considered one of the most important standards. Deep datapath and algorithm complexity have made the verification of such floating-point units a very hard task. Most simulation and reachability analysis verification tools fail to verify a circuit with a deep datapath like most industrial floating-point unit...

Field Programmable Gate Arrays (FPGAs) are frequently used to accelerate signal and image processing algorithms due to their flexibility, relatively low cost, high performance and fast time to market. For those applications where the data has large dynamic range, floating-point arithmetic is desirable due to the inherent limitations of fixed-point arithmetic. Moreover, optimal reconfigurable ha...

The floating point operations are critical to implement on FPGAs due to their complexity of their algorithms. Thus, many scientific problems require floating point arithmetic with high levels of accuracy in their calculations. Therefore, in this paper the proposed work is explored FPGA implementation of Addition/Subtraction for IEEE double precision floating point numbers. This kind of unit can...

Original scientific paper The floating cranes, which transfer payloads during offshore constructions, need meet rigorous demands for efficiency and safety in serious sea conditions while the unexpected motion of the floating crane caused by wave make it even harder. This paper analyses the dynamics of a floating crane and presents an active heave compensation system (HCS) to allow the payloads ...

In this project we explore the capability and flexibility of FPGA solutions in a sense to accelerate scientific computing applications which require very high precision arithmetic, based on IEEE 754 standard 128-bit floating-point number representations. Field Programmable Gate Arrays (FPGA) is increasingly being used to design high end computationally intense microprocessors capable of handlin...

STUDY DESIGN Experimental study. PURPOSE The study aimed to develop a finite element (FE) model to determine the stress on the discs adjacent to the fused segment following different types of floating lumbar spinal fusions. OVERVIEW OF LITERATURE The quantification of the adjacent disc stress following different types of floating lumbar fusions has not been reported. The magnitude of the st...

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...

The Floating Point in two-term Dot-Product of multiplier referred as discrete design. Floating Point is a wide variety for increasing accuracy, high speed, high performance and reducing delay, area and power consumption. This application of floating point is used for algorithms of Digital Signal Processing and Graphics. Many floating point application is to reduce area, from the survey the fuse...
