Abstract

This research is application of neural network technique to optimize convolution operation using mask 3x3 to omit the image blurring effect. This neural network consists of three layers. They are input layer (9 neuron inputs), output layer (1 output neuron) and hidden layer. Each layer is applied to 3, 5 and 7 neuron using back propagation technique. The result shows the using five neurons to hidden layer give the highest value of sound pixel recognizing (76.47%)

Abstract

This article describes about Tanagra software application on data mining. Tanagra is data mining software which can be used to access some existing data mining method. Data is built using excel with text data type. This application use the dataset of women with begnin or malignant. The result inform from 699 sample for Univariate Continuous Statistic have begin 65,52% and malignant 34,48%. The other information is the begnin has less mitos (1,6 : 1,59), the malignant has more ucellshape (6,56 : 3,21)

Abstract

The research implementing ‚ÄúTachogenerator as the sensor for controller of Electric Motor Speed rotation at electric laboratories‚ÄĚ Plant (Object controlled) is controlled by the electric motors speed rotation in AC or DC, by setting armature voltage of motor using digital PID controller and fuzzy logic from Personal Computer (PC). Although the load disturbances are changing significantly, but the motor speed rotation can be stabilized by feedback input from tachogenerator which are the focus in this research. PID controller dan fuzzy Logic controller applications are used to find the advantages the disadvatages or controll methode of motor reliability in dinamic controll (speed rotation) which cause the system more stabil. The result can be seen in maintained system responses and the system reliabilty against disturbances.
