In an important paper, Burer [2] recently showed how to reformulate general mixed-binary quadratic optimization problems (QPs) into copositive programs where a linear functional is minimized over a linearly constrained subset of the cone of completely positive matrices. In this note we interpret the implication from a topological point of view, showing that the Minkowski sum of the lifted feasi...

prediction using pure standards is expected to be biased whenever the slope of the calibration is affected by the presence of sample matrix. moreover, in the presence of unknown spectral interferents, first-order algorithms like partial least squares cannot be used. in this study, a method for determination of carvedilol (car) in tablet and urine samples is proposed by excitation-emission fluor...

The design and implementation of a double precision floating-point IEEE-754 standard adder is described which uses “flagged prefix addition” to merge rounding with the significand addition. The floating-point adder is implemented in 0:5 m CMOS, measures 1:8mm2, has a 3-cycle latency and implements all rounding modes. A modified version of this floating-point adder can perform accumulation in 2-...

The IEEE-754 standard for Floating Point Arithmetic[1] that was in effect at the time of this seminar was adopted in 1985. That standard was intended for hardware implementation, although provisions were made for software implementation for operations. In addition to required operations, an appendix of recommended functions was also specified. Default exception handling was specified, and provi...

Two samples of a standard gelatin were studied, both prepared according to published specifications and washed free from diffusible electrolytes. The isoelectric point of this material was determined in four ways. 1. The pH values of solutions of gelatin in water approached the limit 4.86 +/- 0.01 as the concentration of gelatin was increased. 2. The pH values of acetate buffers were unchanged ...

Function Point (FP) is a software size measure, which includes the standard FP and many different models derived from it. The standard FP method created by Albrecht in 1979 is currently known as the International FP User group (IFPUG) version, which consists of three main parts: The first part is five components, and the second is the complexity weights that include three levels of complexity; ...

Sign bit compression in fixed-point numbering systems can improve the dynamic range and round-off noise for signal processing algorithms. This paper analyses non-standard compression factors (CF) for compressed fixed-point data formats, where sign bit compression is performed on each individual fixed-point number. Although these compression techniques are applicable to other fixed-point formats...
