The speed of image denoising by adaptive thresholding approach in Wavelet Transform (WT) domain depends mainly upon the learning algorithm used for optimising the performance of adaptive thresholding function. In this context, in the literature, steepest gradient-based optimisation technique has been used in WT-based thresholding neural network (WT-TNN) approach, which has low learning speed. In this paper, a new computationally efficient approach, that is, Particle Swarm Optimisation (PSO)-based approach has been proposed in place of steepest gradient-based approach. The proposed hybrid computing approach utilises the features of WT-TNN approach and enhances the speed of optimisation by PSO technique. It also yields better performance of denoising as compared to WT-TNN approach. In the proposed approach, crucial problem of initialisation of thresholding parameters gets automatically sorted out besides learning time becoming independent of noise level of the image. The proposed approach also enhances edge preservation, when implemented with bior6.8 wavelet filters.

Irrigation Systems 101: What you need to know
In the perfect scenario everyone could rely on rainwater for their farming practices, but this is not always the case. This is why employing the right choice from the different irrigation systems available is crucial for agricultural success. Irrigation systems are basically an artificial way to provide water to fertile soil for agricultural purposes. Crop irrigation is necessary to overcome such challenges as rain shortage and drought, and to keep up with the increasing demand for food. There are many options...
Transition metals cobaltites spinel for depollution of NOₓ emissions using SCR technology
Abstract The catalytic performance of various transition metal (M = Cu, Mn, and Ni) cobaltites prepared by nanocasting method were investigated for the selective catalytic reduction (SCR) of NO under lean burn conditions. KIT-6 was used as a hard template in the nanocasting method for preparation of catalysts. The catalyst samples were characterized by various techniques such as XRD, low-temperature N2 physisorption, SEM-EDS, and XPS. The catalysts were examined for the SCR of NO by NH3 and H2-LPG in a packed...
An assessment of sub-standard water pressure in South African potable distribution systems
Sub-standard residual water pressures in urban water distribution systems (WDS) are a prevalent phenomenon in developing countries – South Africa being no exception. The phenomenon of sub-standard pressure is poorly understood, with intermittent supply ultimately resulting when there is no residual pressure left in the system. This research addressed the prevalence and extent of sub-standard pressures by using hydraulic models of potable WDS for 71 South African towns, located in 17 different South African...
Getting to Know Cannabis Farming Israel’s agricultural industry is ripening for the beginning of medical cannabis export, with the expected passage of medical export legislation by the end of the year. The timing is particularly fruitful for growers who are interested in succeeding in a new venture that is still in its infancy. The rewards are also high: Israel’s Health and Finance ministries have assessed that international exports would generate $4 billion in revenues annually. Getting started in...
Sub-micron Bovine Serum Albumin particles
Innovative method for spray drying proteins with high yields. Spray-drying was shown to be a rapid, continuous, cost-effective, reproducible and scalable process for the production of dry powders from a liquid. Moreover, in the recent years, spray drying was identified by the pharmaceutical industry as a suitable method to produce protein particles used in pulmonary, nasal and oral delivery. Due to its property, bovine serum albumin (BSA) has many applications in life science disciplines, such as cell culture,...
