Application of neural networks for prediction of doubly fed induction generator’s equivalent circuit parameters used in wind generators.

Abstract: Due to its merits, the doubly fed induction generator (DFIG) finds its application in sizeable grid-connected power systems. Its equivalent circuit parameter typically represents DFIG by stator and rotor winding resistance, reactance and mutual reactance.

In this paper, the equivalent circuit parameters of DFIG are predicted using deep neural networks created and simulated with 'Neural Designer '. This article uses Neural Designer to improve their predictive model with different algorithms available in the program, such as selection order and neuron selection features. This algorithm increases the accuracy of the neural network and optimizes the computational cost.

Computerized Detection of JWH Synthetic Cannabinoids Class Membership Based on Machine Learning Algorithms and Molecular Descriptors

Abstract: The detection of the JWH synthetic cannabinoids and non-JWH cannabinoids and discriminating them from other compounds of forensic interest is extremely important. These compounds have very limited legal uses. Hence, there are very few studies about their pharmacological activity and toxicity. The most important characteristic of any system screening for these drugs of abuse is its capacity to recognize correctly the class identity of the positive samples, which, according to the requirements for a forensic tool, should not be misclassified under any circumstances.

This paper uses Neural Designer to create a predictive model for detecting these substances. The researcher draw statistical conclusions with the help of model analysis utilities included in Neural Designer

Experimental Investigation on use of Molecular Sieve4A as Desiccant in Heatless Desiccant Air Dryer

Abstract: Moisture in compressed air, even in small amounts, can cause damage to the final products. As a result, removing moisture from compressed air is particularly desirable, and to accomplish that, a heatless desiccant air dryer can be used. Therefore, the usage of solid desiccant molecular sieve 4A in a heatless air dryer with a capacity of 10 CFM is investigated in this research.

Using Neural Designer, The researcher builds a neural network created artificially to forecast the dew point temperature in a heatless air dryer over a more extended period. All input parameters, such as flow rate, relative humidity, pressure, etc., have been kept constant, and the model predicts the outlet dew point temperature over time.

The training and analysis of the model are performed using the Model Training and Testing analysis features from Neural Designer and help to conclude the efficiency of this desiccant with great accuracy.

Implication of Artificial Intelligence Approach On Groundwater Level

Abstract: Groundwater is considered one of the most critical water resources for humans and the environment, but now this is declining at a faster rate. Various models have been developed to analyze the hydrological aspects of water resources. However, due to the complexity of data acquisition and extensive data requirement for physical models, they are tough to model the water resources problems.

The research aims to simulate and model groundwater levels and find how much impact climate change is imposing in groundwater scenarios using Artificial Intelligence as an alternative approach over physical-based models. In this case, the optimal neural network architecture is obtained after several trials with a different number of layers and neurons using Neural Designer and its features.

In this paper, the impact of climate change on groundwater levels is studied using an artificial neural network approach, concluding that we are in an alarming situation.

Key Features of the Performance of Chinese Musicians

Abstract: The article is devoted to the methods of teaching saxophone playing within the framework of two classical approaches to teaching. The purpose of the article is to identify the features of two classical approaches to teaching the saxophone within the French and American traditions from the point of view of the peculiarities of the perception of these two techniques by Chinese students.

In terms of learning to play the saxophone, it is necessary to take into account the methodological differences in techniques and methods of sound production. At the same time, in the future, it is necessary to investigate the methodology of teaching saxophone playing from the perspective of a polystylistic approach, when the goal of training musicians is the ability to play all styles at an equal quality level.

In this paper, ‘Neural Designer’ is used for analytics purposes without using complex and non-friendly statistical programs like R. The analytical capacities of Neural Designer allow different types of the researcher to perform analyses in a very easy, clear, and understandable way, even using tools like exporting charts or graphs.

Deep neural networks applications in the study of a geological indicator

Abstract: The differences between shallow neural networks and deep neural networks are considered. Finally, data from the operational exploration of an open pit mine are used to train different types of deep neural networks to predict a helpful indicator.

Neural Designer is used in this case to train several neural networks, compare their performance, and choose the best one for a case study using the different parameters provided by the program simply and concisely.

The research concludes in this case that a two-layer neural network provides excellent performance and balance between accuracy and computational cost. Moreover, a neural network with two two-layers with four neurons is the optimal solution because of the correlation with higher accuracy, lack of overtraining, and a simplified structure.

Classification of Pb recovery affecting factors with artificial ıntelligence based algorithms

Abstract: Lead (Pb) is one of the most widely used non-ferrous materials. Many methods have been developed to produce lead metal from initial raw materials or secondary resources.

The Artificial Neural Network structure was proposed with 4 inputs for predicting Pb recovery percentage. Four input parameters: temperature, NaCl concentration, time, and solid to liquid ratio values were selected based on physical considerations and the experimental test results.

In this case, Neural Designer provides a simple and complete way to perform the training and analysis of the Neural Network and provides a Normalized Squared Selection Error of 0.2374. Moreover, this model provided by Neural Designer allows the researcher to conclude that :

• There is a strong correlation between the Pb recovery amount with the Solid-liquid ratio and NaCl concentration
• The outcomes of the study can be assessed by other artificial and mathematical systems for a better understanding of input effects on Pb recovery amounts.

This statistical analysis indicates that lead recoveries up to 98 % could be obtained at a low pulp density with considerable NaCl concentration on the laboratory scale. Compared with previous studies, these results yielded very consistent findings in terms of Pb leach efficiency

Flexural strength estimation of basalt fiber reinforced fly-ash added gypsum based composites

Abstract: Gypsum and fiber-reinforced gypsum-based composites are widely used in many construction projects. Much research has been conducted on these types of composites; however, there are very limited literature studies focused on the estimation of flexural strength of fiber-reinforced gypsum-based composites. And there is no current study on the mechanical strength estimation of these types of composites

There is a large database of experimental information with 275 results with 5 inputs: fly ash, basalt, superplasticizer contents, water to binder ratio, and slump values are used to build and train the model.

In this case, ' Neural Designer ' calculates a neural network model with a good correlation between the flexural strength and predicted data.

Predicting the Properties of High-Performance Epoxy Resin by Machine Learning Using Molecular Dynamics Simulations

Abstract: The performance of epoxy systems varies significantly depending on the composition of the base resin and curing agent. However, there are limitations in exploring numerous formulations of epoxy resins to optimize adhesive properties because of the expense and time-consuming nature of the trial-and-error process. Herein, molecular dynamics (MD) simulations and machine learning (ML) methods were used to overcome these challenges and predict the adhesive properties of epoxy resin.

Datasets for diverse epoxy adhesive formulations were constructed by considering the degree of crosslinking, free volume, cohesive energy density, modulus, and glass transition temperature. ‘The researcher used neural Designer’ to train the model using these datasets and compare all the models developed with the mean squared error. Also, it is used to generate various statistical results, plots, and charts.

Investigations into succinic acid fermentation

Abstract: Succinic acid (SA) is an essential chemical intermediate from which fine chemicals ( e.g. detergents), additives (for pharmaceuticals, food (taste), plant growth stimulants), as well as other essential intermediates (maleic anhydride, succinimide, 2-pyrrolidinone, dimethyl succinate), can be manufactured. A neural network for modelling and describing how factors influence SA production was established based on different fermentations.

Fermentation data were combined into a single MS Excel spreadsheet and exported to a tab-delimited text file, which could be imported into ‘Neural Designer software. 9 variables, i.e. 7 inputs (time, lactic acid, acetic acid, propionic acid, glycerol, ethanol, total sugar) and 2 outputs (succinic acid, CDW), were applied to 58 fermentation samples. It was also used ‘Neural Designer’ to create and improve the neural network architecture with the order selection algorithm and the algorithm “growing inputs”.

In this case, ‘Neural Designer’ was a key part of the study, because it provides a simple and intuitive way to model this problem and draw conclusions.
