A simple, faster method for kinetic proximity problems

For a set of n points in the plane, this paper presents simple kinetic data structures (KDS’s) for solutions to some fundamental proximity problems, namely, the all nearest neighbors problem, the closest pair problem, and the Euclidean minimum spanning tree (EMST) problem. Also, the paper introduces KDS’s for maintenance of two well-studied sparse proximity graphs, the Yao graph and the Semi-Ya...

A convenient Simple Method for Synthesis of Meta-iodobenzylguanidine (MIBG)

Radioiodinated meta iodobenzylguanidine (MIBG) is one of the important radiopharmaceuticals in Nuclear Medicine. [123/131I]MIBG is used for imaging of Adrenal medulla, studying heart sympathetic nerves, treatment of pheochromacytoma and neuroblastoma. For clinical application, radioiodinated MIBG is prepared through isotopic exchange method, which includes replacement of radioactive iodine in a...

A Simple Method for Modeling Open Cracked Beam

Abstract A simple method is proposed to model the open cracked beam structures. In this method, crack is modeled as a beam element. Hence cracked beam can be assumed to be a beam with stepped cross sections, and problem of determining natural frequency and mode shape of cracked beam, can be solved as determining these characteristics for a beam with different length and cross section. With this...

A Simple Precipitation Method for Synthesis CoFe2O4 Nanoparticles

Magnetic CoFe2O4 nanoparticles were synthesized via a simple chemical reaction using precipitation method. The obtained materials consist of ferrite particles with average diameter of 25 nm. The effect of different surfactants such as cationic, anionic and neutral on the morphology of the products was investigated. Scanning electron microscopy was used to study the structure and particle size o...
