Components of Soft Computing for Epileptic Seizure Prediction and Detection

Components of soft computing include machine learning, fuzzy logic, evolutionary computation, and probabilistic theory. These components have the cognitive ability to learn effectively. They deal with imprecision and good tolerance of uncertainty. Components of soft computing are needed for developing automated expert systems. These systems reduce human interventions so as to complete a task essentially. Automated expert systems are developed in order to perform difficult jobs. The systems have been trained and tested using soft computing techniques. These systems are required in all kinds of fields and are especially very useful in medical diagnosis. This chapter describes the components of soft computing and review of some analyses regarding EEG signal classification. From those analyses, this chapter concludes that a number of features extracted are very important and relevant features for classifier can give better accuracy of classification. The classifier with a suitable learning method can perform well for automated epileptic seizure detection systems. Further, the decomposition of EEG signal at level 4 is sufficient for seizure detection

STUDY ON RECYCLED AGGREGATE CONCRETE WITH BLENDED GGBS

Abstract With the rapid growth in construction activities, it is important to assess the amount of construction and demolition waste being generated and analyse the practices needed to handle this waste from the point of waste management and disposal and also with regard to waste utilization in concrete from the sustainability aspects. Construction and Demolition (C&D) waste constitutes a major portion of total solid waste production in the world, and most of it is used in landfills. Research by concrete engineers has clearly suggested the possibility of appropriately treating and reusing such waste as aggregate once again in concrete, especially in applications such as bed concrete and in road beds for pavement i.e. where works are of less importance as regards to the strength. The use of such waste as recycled aggregate in concrete can be useful for both environmental and economic aspects in the construction industry. In present study, five concrete mixes were used; first mix had only natural coarse aggregate and in remaining mixes natural coarse aggregate was partial replaced by 10%, 20%, 30% and 40% recycled coarse aggregate. In all the mix cement was replaced by 10% GGBS. Here an attempt is made to assess the strength and durability characteristics of concrete made using construction and demolition waste recycled coarse aggregate

STRENGTH PROPERTIES OF HIGH STRENGTH CONCRETE USING RECYCLED CONCRETE AGGREGATE

The demand for creativity and luxury over the world is increasing the demolition activities for the construction of new buildings in place of old ones. Thus huge amount of demolition wastes is being generated around the world causing a problem for its disposal. Further to meet the needs of growing construction industry there is a heavy demand for natural aggregates because of which they are getting depleted. Hence to overcome the depletion and for making a sustainable world the use of recycled aggregates came into picture. Recycled aggregates have found their use in many works like pavements, kerbs etc. but they are rarely used for engineering works. This project aims at finding the usage of recycled aggregates for high strength concrete. The present research studies the strength of concrete made with different replacement levels of natural aggregates with recycled aggregates. The replacement ratios considered are 0.54, 0.67 and 0.81. Specimens are made to find the compressive strength, tensile strength and flexural strength at different W/B ratios and different F.A to T.A ratio and thus the applicability is studied

Phase transfer of platinum nanoparticles from aqueous to organic solutions using fatty amine molecules

In this report we demonstrate a simple process based on amine chemistry for the phase transfer of platinum nanoparticles from an aqueous to an organic solution. The phase transfer was accomplished by vigorous shaking of a biphasic mixture of platinum nanoparticles synthesised in an aqueous medium and octadecylamine (ODA) in hexane. During shaking of the biphasic mixture, the aqueous platinum nanoparticles complex via either coordination bond formation or weak covalent interaction with the ODA molecules present in the organic phase. This process renders the nanoparticles sufficiently hydrophobic and dispersible in the organic phase. The ODA-stabilised platinum nanoparticles could be separated out from hexane in the form of a powder that is readily redispersible in weakly polar and non-polar organic solvents. The ODA-capped platinum nanoparticles show high catalytic activity in hydrogenation reactions and this is demonstrated in the efficient conversion of styrene to ethyl benzene. The nature of binding of the ODA molecules to the platinum nanoparticles surface was characterised by thermogravimetry, transmission electron microscopy (TEM), X-ray photoemission spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR)

Policy of foreign direct investment liberalisation in India: implications for retail sector

This study has analysed the impact of liberalisation of Indian economy and FDI policy on the retail sector since its implementation in the 1990s. It also further analyses sub-categories by investigating its impact on the unorganised retail sector and the flow of FDI in single-brand retail and multi-brand retail sectors. A comprehensive and critical review of the existing evidence on the subject was carried out, and descriptive statistical analysis of data from 1991 to 2013 was performed which leads to conclude that the policy of FDI liberalisation has proved to provide diversification and sustainable development to the Indian economy and specifically retail sector which is considered to be one of the significant pillars of economy. Furthermore, for continuous growth of the economy, it seems vital to encourage more investment in other sectors by liberalising the restrictive policies

Wound contraction effects and antibacterial properties of Tualang honey on full-thickness burn wounds in rats in comparison to hydrofibre

<p>Abstract</p> <p>Background</p> <p>Full-thickness burn wounds require excision and skin grafting. Multiple surgical procedures are inevitable in managing moderate to severe full-thickness burns. Wound bed preparations prior to surgery are necessary in order to prevent wound infection and promote wound healing. Honey can be used to treat burn wounds. However, not all the honey is the same. This study aims to evaluate the wound contraction and antibacterial properties of locally-produced <it>Tualang </it>honey on managing full-thickness burn wounds <it>in vivo</it>.</p> <p>Methods</p> <p>Thirty-six female <it>Sprague Dawley </it>rats were randomly divided into three groups. Under anaesthesia, three full-thickness burn wounds were created on the dorsum of the rats. The full-thickness burn wounds were inoculated with a specific organism (10⁴), namely <it>Pseudomonas aeruginosa </it>(n = 12), <it>Klebsiella pneumoniae </it>(n = 12), or <it>Acinetobacter baumannii </it>(n = 12). The three burn wounds were dressed with <it>Tualang </it>honey, hydrofibre and hydrofibre silver respectively. Swab samples were obtained every 3 days (day 3, 6, 9, 12, 15, 18 and 21) for quantitative and semi-quantitative microbiological analyses. Clinical assessments, including observations concerning the appearance and wound size, were measured at the same time.</p> <p>Results</p> <p>There was a rapid 32.26% reduction in wound size by day 6 (<it>p </it>= 0.008) in the <it>Tualang </it>honey-treated wounds, and 49.27% by day 15 (<it>p </it>= 0.005). The wounds remained smaller by day 18 (<it>p </it>< 0.032). <it>Tualang </it>honey-treated rats demonstrated a reduction in bacterial growth in <it>Pseudomonas aeruginosa </it>inoculated wounds (<it>p </it>= 0.005). However, hydrofibre silver and hydrofibre-treated wounds are superior to honey-treated wounds with <it>Acinetobacter baumannii </it>(<it>p </it>= 0.035). There was no statistical significant of antibacterial property in <it>Klebsiella pneumonia </it>inoculated wounds.</p> <p>Conclusions</p> <p><it>Tualang </it>honey has better results with regards to its control of <it>Pseudomonas aeruginosa </it>and its wound contraction effects on full-thickness burn wound <it>in vivo</it>.</p

Poly-β-hydroxybutyrate administration during early life: effects on performance, immunity and microbial community of European sea bass yolk-sac larvae

The reliable production of marine fish larvae is one of the major bottlenecks in aquaculture due to high mortalities mainly caused by infectious diseases. To evaluate if the compound poly-β-hydroxybutyrate (PHB) might be a suitable immunoprophylactic measure in fish larviculture, its capacity to improve immunity and performance in European sea bass (Dicentrarchus labrax) yolk-sac larvae was explored. PHB was applied from mouth opening onwards to stimulate the developing larval immune system at the earliest possible point in time. Larval survival, growth, microbiota composition, gene expression profiles and disease resistance were assessed. PHB administration improved larval survival and, furthermore, altered the larva-associated microbiota composition. The bacterial challenge test using pathogenic Vibrio anguillarum revealed that the larval disease resistance was not influenced by PHB. The expression profiles of 26 genes involved e.g. in the immune response showed that PHB affected the expression of the antimicrobial peptides ferritin (fer) and dicentracin (dic), however, the response to PHB was inconsistent and weaker than previously demonstrated for sea bass post-larvae. Hence, the present study highlights the need for more research focusing on the immunostimulation of different early developmental stages for gaining a more comprehensive picture and advancing a sustainable production of high quality fry
