It is easy to underestimate the difficulties of using floating-point numbers in programming. This is especially the case in pre-university informatics education and competitions, where one is often led to believe that floating-point arithmetic is a good approximation of the real number system. However, most of the mathematical laws valid for real numbers break down when applied to floating-poin...
PURPOSE The aim of the present study was to improve the bioavailability of itopride (ITO) and sustain its action by formulating as a floating dosage form. MATERIALS AND METHODS Sustained-release floating tablets of ITO hydrochloride (HCl) were prepared by direct compression using different hydrocolloid polymers such as hydroxypropyl methylcellulose and ethylcellulose and/or methacrylic acid p...
1 This paper compares financial costs and benefits of floating rice-based and intensive rice farming systems using data from focus group discussions and household survey in four locations in the Mekong Delta. We argue that the net financial benefit per 1000m 2 of integrated floating rice-based farming systems is greater than the net financial benefit of intensive rice farming system. The total ...
this study was performed to design bilayer regioselective floating tablets of atenolol and lovastatin to give immediate release of lovastatin and sustained release of atenolol. bilayer floating tablets comprised two layers, i.e immediate release and controlled release layers. the immediate release layer comprised sodium starch glycollate as a super disintegrant and the sustained release layer c...
Turbochargers are widely used on commercial automotive vehicles, power generation and marine applications. A comprehensive model for a turbocharger would be an effective tool for fault detection. In this paper, research focus on mathematical modelling of turbochargers supported on floating ring bearings in rotordynamics. Nonlinear hydrodynamic forces are considered in order to describe the dyna...
Synopsys GmbH, Herzogenrath, Germany Abstract “How can something so trivial cause such a delay in your project?” This is one of the most frequently asked questions from engineers and managers who never had to suffer from the pains of converting a floating-point algorithm or system to a fixed-point representation. The latter becomes the golden reference and basis for the implementation in hardwa...
Unlike the trapping of time-harmonic water waves by fixed obstacles, the oscillation of freely floating structures gives rise to a complex nonlinear spectral problem. Still, through a convenient elimination scheme the system simplifies to a linear spectral problem for a self-adjoint operator in a Hilbert space. Under symmetry assumptions on the geometry of the fluid domain, we present condition...
This paper describes the Intel Touchstone Gamma Prototype, a distributed memory MIMD parallel computer based on the new Intel i860 floating point processor. With 128 nodes, this system has a theoretical peak performance of over seven GFLOPS. This paper presents some initial performance results on this system, including results for individual node computation, message passing and complete applic...
This paper addresses the singularities avoidance problem while performing a grasping maneuver in teleoperation with a manipulator mounted on a free-floating spacecraft. Firstly, the independence of the singularities of the end-effector Jacobian of a generic free-floating system from the inertial parameters of the last link is demonstrated. Secondly, the possibility to represent all the singular...
Dynamic Singularities are shown for free-floating space manipulator systems where the spacecraft moves in response to manipulator motions without compensation from its attitude control system. At a dynamic singularity the manipulator is unable to move its end-effector in some inertial direction; thus dynamic singularities must be considered in the design, planning, and control of free-floating ...
