We describe a hybrid meta-heuristic algorithm for combinatorial optimization problems with a specific reference to the travelling salesman problem (TSP). The method is a combination of a genetic algorithm (GA) and greedy randomized adaptive search procedure (GRASP). A new adaptive fuzzy a greedy search operator is developed for this hybrid method. Computational experiments using a wide range of...

alkyl imidazolines have been reportedly used in a wide range of industrial formulations with different applications. ethoxylated alkyl imidazolines with appropriate ethoxylation degrees can be used as antioxidants and retarders in the formation of peroxides resulting from oxidation in hydrocarbon media. in this work, ethoxylated imidazolines were shown to be more effective in hydrocarbon media ...

This paper presents an algorithm for compositing a high dynamic range (HDR) image from multi-exposure images, considering inconsistent pixels for the reduction of ghost artifacts. In HDR images, ghost artifacts may appear when there are moving objects while taking multiple images with different exposures. To prevent such artifacts, it is important to detect inconsistent pixels caused by moving ...

A 63-year-old male was referred for jaundice and general fatigue. Computed tomography of the abdomen showed several gallbladder stones and gallbladder wall thickening. The laboratory data was the following: total bilirubin 2.2 mg/dL (reference range: 0.2-1.1 mg/dL), direct-bilirubin 0.6 mg/dL (reference range: 0-0.2 mg/dL), SGOT 46 IU/L (reference range: 12-32 IU/L), SGPT 79 IU/L (reference ran...

BACKGROUND A conventional gravimetry and electro-gravimetry study has been carried out for the precise and accurate purity determination of lead (Pb) in high purity lead stick and for preparation of reference standard. Reference materials are standards containing a known amount of an analyte and provide a reference value to determine unknown concentrations or to calibrate analytical instruments...

This paper presents a new reverse converter architecture for the moduli set { 2 -1, 2, 2 +1, 2-1}. It exploits the special properties of the numbers of the form 1 2 ± , and extends the dynamic range of the present triple moduli based systems. Here we use a combination of CRT and MRC for reverse conversion. With a pipelined system the throughput rate is that of a single 3n+1 bit binary adder delay.

OBJECTIVES To explore growth data (height-for-age, weight-for-age and BMI-for-age) of children living in poor socioeconomic conditions in rural areas of Chin State, Burma/Myanmar; and to compare these data with the growth and development z-score (GDZ) values for school-aged children and adolescents, provided by the WHO. SETTING A support and educational programme, run by the Swedish associati...
