cantaloupe (cucumis melo) volume was measured using water displacement and image processing methods. the volume determined from image processing method was compared to the volume determined by the water displacement method using the paired samples t-test and the bland-altman approach. the paired samples t-test results showed that the volume determined by image processing method was not signific...

abstract         background and objective: hirudin is an anticoagulant polypeptide secreted from the salivary glands of leeches. recombinant hirudin is a strong anticoagulant agent in arterial and venous thrombosis. the aim of this study was to evaluate the effect of inserting protein a signal peptide sequence of pezz18 plasmid on expression and secretion of the recombinant hirudin in e.coli.  ...

the objective of this research was to develop a suitable method for color sorting of fruits. accordingly, a color-sorting system was designed and a prototype developed and then tested. this system includes an optic head which is designed to develop a reflection of the fruit. output of the head is then processed in an electronic control system which generates the appropriate signal for ejection ...

sorting and classification of agricultural products by machine vision system reduce costs and increase quality and accuracy. this research was performed to develop an algorithm and machine vision system for separating dirty and defects eggs and classifying by volume and weight. this machine installed on transport line egg in agriculture included a digital camera, computer and mechanical device ...

there are instances in which it is desirable to determine relationships among fruit physical attributes. for example, fruits are often graded on the basis of size and projected area, but it may be more suitable and/or economical to develop a machine which grades by mass. therefore, a relationship between mass and dimensions or projected areas and/ or volume of fruits is needed. various grad...

Background and Objectives: The inability of classic fluorescence-activated cell sorting to single cancer cell sorting is one of the most significant drawbacks of this method. The sorting of cancer cells in microdroplets significantly influences our ability to analyze cancer cell proteins. Material and Methods: We adapted a developed microfluidic device as a 3D in vitro model to sorted MCF-7 c...

spike sorting is a class of techniques used in the analysis of electrophysiological data. studying the dynamics of neural activity via electrical recording relies on the ability to detect and sort neural spikes recorded from a number of neurons by the same electrode. this article reviews methods for detecting and classifying action potentials, a problem commonly referred to as spike sorting.
