In this work, we compare the technical and economic performance of a solar organic Rankine cycle (s-ORC) system with thermal energy storage (TES) and a solar photovoltaic (PV) system with battery storage at a capacity of 50 kWe. A two-dimensional variable space, comprising solar field area and storage capacity is swept for optimum operational zones of five performance indicators, namely annual energy...
We address the problem of audio search in the framework of Hopfield net associative memory, to realize its ideal functionality as a content based information retrieval system. Towards this, we examine various issues such as i) how the capacity of the Hopfield net is limited (far below the theoretical limit) for correlated patterns, and how its capacity could be significantly enhanced by a principal...
Medicines are the primitive solution for the prevention and cure for most of the diseases. Many risky diseases can be cured and prevented with the use of proper medication. The main objective of our proposed system, is to ensure a user friendly design that the patients can use as a reminder alert to take their daily medications on time. A wearable device is designed which is used to monitor the heartrate...
We examine the problem of how the Hopfield net associative memory framework can be adapted for speech recognition, by first identifying specific issues in such an adaptation, such as i) the problem of representing spectral feature vector sequences in the form of time normalized time-frequency (t-f) constellations, ii) the issue of limited capacity of the network when the temporal patterns are highly...
Predictive analysis using machine learning has been gaining popularity in recent times. In this paper, the Random Forest regression model is used to predict popularity of articles from the Online News Popularity data set. The performance of the Random Forest model is investigated and compared with other models. Impact of standardization, regularization, correlation, high bias/high variance and feature...
The performance of Switch and Stay Combiner (SSC) over ‘independent’ and ‘independent and identically distributed’ (i.i.d.) K fading channels is analyzed and evaluated in this paper. The K distribution used to model composite fading channels can be obtained by averaging the conditional Rayleigh Probability Density Function (PDF) over the Gamma PDF. Expressions for the outage probability, moments of...
