KLASIFIKASI CITRA MAMOGRAFI MENGGUNAKAN JARINGAN SYARAF TIRUAN
Get PDFThere are abnormalities in breast tissue which can be detected by mammogram images analysis. One of those abnormalities is microcalcification. Microcalcifications are small calcium deposits in the breast tissue that can be seen only on a mammogram and can be an indicator of breast cancer. The main objective of this research is to automatically recognize the pattern of two types of breast tissues, i.e. normal tissue and breast tissue which contain microcalcifications in digital mammograms using Matlab software tools. In this research, pattern recognition is carried out using Artificial Neural Network (ANN), i.e. LVQ (Learning Vector Quantization). The pattern recognition is formulated as a supervised-learning problem and classification was based on six-feature input given to the ANN. The system recognizes the pattern in three steps. Firstly, a tophat transformation is applied on the images, and then features of the images are extracted based on images pixel values. Finally, image classification is carried out in recognizing the pattern. The research uses 26 digital mammograms, consist of 16 normal mammograms and 10 mammograms which contain microcalcifications. The results show that the LVQ best performance in recognizing the pattern is 97%, using learning rate and decrement of learning rate equal to 0.1
Aplikasi WiMAX
Get PDFWiMAX is Broadband Wireless Acces (BWA) technology evolution with interactive fitur. WiMAX not only have issue about data speed problem but also about open standard. It means, communications between WiMax instruments between some different vendors are not proprietary. WimAX orientations are not only for fixed market, but also for portable and mobile market. WiMAX with high speed data (up to 70 MBps) is suitable to apply in last mile broadband connections, backhaul and high speed enterprise
VIDEO STREAMING DENGAN VIDEOLAN PROJECT
Get PDFStreaming is process of continuing data sending by broadcasting trough internet which showed by streaming application at PC client. The sending data packaging is compressing to make sending process is easy. Streaming can be done by input media variation and client has a change to benefit just after server sending the distreaming data and running in VLC media player. VideoLAN Client (VLC) is a media to streaming which can be applied as transmitter and receiver. VLC can compress and decompress audio and video data from some input media. It shows data result of streaming which have picture and voice quality as well as the source
ANALISIS KARAKTERISTIK MATERIAL MENGGUNAKAN PARALEL PLATE SAMPLE HOLDER PADA BROADBAND DIELEKTRIK SPEKTROMETER
Get PDFDielectric spektrometer is used to measure complex dielectric function of material which depends on the frequency. The measured in domain frequency learn about movement of dipole’s molecule and electric conductions in capasitor charging process. The most familiar measuring method of frequency area is parallel plat capasitor and four electrode system (V. Raicu et al, 1994). In this method, the measuring material is placed betwen two electroda in parallel place. This configuration produce a capasitor system which is possible to measure the complex impedance of the capasitor sample. In this research, measuring and analyzing the material characterization are done in high frequence to design circuit and development of many material. Based on this reason, this reseach uses dielectric spectrometer system with HP Impedance Analyzer 4191ª RF and frequency 1-1000 MHz. Spectrometer can be used on complex permittivity to measure the compact material. The measuring result can be implemented in high frequency range using phenomenological relaxation model. However, the accuracy of such predictions would need careful further study.

Rancang Bangun Tacho Generator Sebagai Sensor Kecepatan Pada Praktikum Kendali Motor-Motor Listrik
Get PDFoai:ojs2.buletinnagari.lppm.unand.ac.id:article/4The research implementing “Tachogenerator as the sensor for controller of Electric Motor Speed rotation at electric laboratories” 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
PENAMBANGAN DATA FORMAT TEXT EXCEL DENGAN SOFTWARE TANAGRA
Get PDFThis 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
