Visual attention-based leukocyte image segmentation using extreme learning machine

Abstract: The existence of computer aided automatic analysis came to light over a century ago and yet the acquisition of visual attention-based segmentation is still in its infancy despite mammoth advances in clinical leukocyte analysis, advanced neurocomputing and fast growing engineering technology. This paper presents a framework for novel segmentation model for leukocyte images using extreme learning machine ELM. The automatic analysis of microscopic leukocyte is an important task for diagnosticing many types of diseases namely leukaemia, malaria, psoriasis, AIDS, etc. The effective samples for training are obtained by saliency map of visual attention-based model. While in the learning stage, the effective samples are trained using ELM and segment leukocytes from blood smear images. The proposed framework is fully automatic and the experimental results outperform the state-of-the-art approaches.

Design and Analysis of Universal Gripper for Robotics Applications

Abstract: A universal gripper is a component that consists of fine dust material enclosed in fine rubbery membrane for holding and assembly. The gripper is especially applied for quickly gripping and discharging large number of objects having complex geometries in wide applications. The objects which are in various shapes and different geometries are difficult to grasp which confirms that it is not suitable for apply in various pick and place operations. In this project, a low cost modular gripper is implemented with suitable mechanical design, structural analysis and real time analysis. In this association, the designed gripper can hold many parts and place it at once while sustaining relative distance and relative coordination at their state. The universal gripper acts as a vacuum tube to grip the object it needs to relocate. This universal gripper can hold various objects such as eggs, grocery items, industrial components, heavy objects etc., therefore, a selected experimental setup has been developed with the composition of shapeless gripper and perform simulation in holding of the different items. Results of the tests and experiments shows the proposed Universal Gripper are validated with feasibility options.

Generation of bioenergy from industrial waste using microbial fuel cell technology for the sustainable future

Abstract: At the present time, treatment of industrial waste and biorefinery process is intricate ones in industrial process because of high energy requirements and expensive nature for biorefinery process. To overcome this concern, an unconventional technology is needed for the efficient operation which recovers useful energy from the industrial waste to make this operation a sustainable one. The conventional biodegradation processes have concentrated on humiliating toxic organic pollutants and have omitted the extrication of chemical energy from it, which in turn wasted as biomass. These unnecessary biomass can cause clogging in bioreactor, retardation of mass transfer, and other bioprocesses. To overcome the drawbacks in existing industrial effluent treatment processes, researchers paid attention on microbial fuel cells (MFCs). Currently, MFC is one of the fascinating technologies for treating industrial effluents as well as producing bioenergy, biogas, and chemicals. MFC is a biorefinery process and also cost effective for industries which have zero effluent discharge system. The present chapter throws light upon the different aspects of MFC to treat industrial waste that has more organic waste in a batch and fed-batch mode. Performance of MFC depends on electrode materials, living biocatalyst, and electrochemically active biofilm developed at anode. Carbon-based electrodes derived from waste materials are used as electrodes (both anode and cathode) and employed in MFCs. The reasons behind it may be due to their nontoxic nature, biocompatibility, long durability, good conductivity as well as relatively low cost. This chapter describes elaborately about the possibilities of bioenergy from industrial waste, effects of industrial waste on environment, traditional treatment methods and its demerits, MFC concepts, prospects, confront, applications, its design and configuration, challenges, and next-generation point of view.

Investigación sobre las propiedades mecánicas y de corrosión del compuesto de matriz metálica Al 7075/Redmud.

Abstract: Investigation in this paper is mechanical properties and corrosion properties of Al 7075 metal matrix composites. Al 7075 metal matrix composite is prepared from Al 7075 as a matrix and redmud as a reinforcement by using two step stir casting process. Volume percentage of reinforcement is varied from 0% to 15%. The experimental density of the composite material produced was calculated according to the Archimedes principle, greater than the basic matrix. Uniform distribution of the reinforcement and matrix in the composite is studied by using optical micrographs and microhardness of the composite is measured by using Vickers hardness testing machine. The microhardness of the composite was increased while the reinforcement went from 0% to 15%. The tensile strength of the composite material is raised at 5% of the reinforcement tolerance (326 MPa), which is higher than the base matrix. The Al 7075 metal matrix composites have a lower corrosion rate in a 3.5% NaCl solution than the base matrix. As the volume percentage increase in red mud, was reduced the corrosion rate of the composites.
