Due to the increasing demand in agricultural industry, need effectively grow a plant and increase its yield is very important. In order do so, it important monitor during growth period, as well as, at time of harvest. this paper image processing used tool diseases on fruits farming, right from plantation harvesting. For purpose artificial neural network concept used. Three grapes two apple have been selected. The system uses databases, one for training already stored disease images other...

A long-standing hypothesis termed "Hebbian plasticity" suggests that memories are formed through strengthening of synaptic connections between neurons with correlated activity. In contrast, other theories propose coactivation Hebbian and neuromodulatory processes produce the underlies memory formation. Using optogenetics we directly tested whether plasticity alone is both necessary sufficient to physiological changes mediating actual formation in behaving animals. Our previous work this...

Depression is one of the habitual psychological well-being diseases and a significant number depressed individuals end their lives. People suffering from depression don’t ask for help doctors due to hesitation or unawareness about that causes delay in diagnosis treatment. A lot people share opinions emotions on social networking sites. Several studies site posts related rely upon Facebook, Twitter, Blogs, other networks because they recording behavioral attributes which are person’s...

Abstract In the past few decades there has been operating analysis on emotion expression recognition due to great intra-class deviation also it is still challenging. Maximum number of research work performs best controlled datasets (i.e., small with less features), whereas fails operate well and it’s challenging varies variations in images even partial faces. modern years, many works have introduced an end-to-end plan for recognition, utilizing deep learning models. Although a task, seems be...

Abstract: Methacrylic-based copolymers in drug-delivery systems demonstrate a pH-sensitive drug-releasing behavior the colon. In this study, of methacrylic acid and 2-ethyl hexyl acrylate were prepared using microemulsion polymerization technique. The purified copolymer was characterized by Fourier transform infrared spectroscopy, proton nuclear magnetic resonance differential scanning calorimetry. 5-Fluorouracil (5-FU) entrapped within methacrylic-based solvent evaporation method. size...

Predicting PV system electricity output is necessary for daily operational management and annual power planning when integrating solar collector-based photovoltaic (PV) stations into micro grids. Tilting the panels at ideal angle to maximize energy capture station production. This optimal tilt (OTA) must be predicted as it a nonlinear function of total radiation, diffuse direct radiation. research explores use feature selection-based artificial neural networks (ANN) with various machine...

Optical tomography is a technique which used to diagnose breast cancer non-invasively at early stage. The challenge faced in optical that light radiations scatter lot biological tissue. Therefore, need arises study the behaviour of propagation through can be done either using stochastic models like Monte Carlo methods or by deterministic Finite element methods. An attempt has been made tissue both and comparative carried out.

In the framework of convolutional neural networks that lie at heart deep learning, downsampling is often performed with a max-pooling operation only retains element maximum activation, while completely discarding information contained in other elements pooling region. To address this issue, novel scheme, Ordinal Pooling Network (OPN), introduced work. OPN rearranges all region sequence and assigns different weights to these based upon their orders sequence, where are learned via...
