Sistem Pencatat Data Percakapan Telepon Dengan Deteksi Sinyal Pandu Secara Otomatis

The growth of telecommunication technology has influenced telecommunication businesses which have become more interesting. One of the telecommunication businesses is telephony billing systems. There have been many kinds of equipments that would be able to support that business, called Telephony Billing System Equipment. Some of them use computer, and the others do not. In this project, theTelephony Billing System Equipment was designed without computer and could detect pilot signals automatically. There were four kinds of pilot signals used, that were a 16 KHz injection signal, a reverse polarity, a ringback tone, and human voice responses. The system would calculate the telephony billing and then print the detailed billing. The system built was used microcontroller AT89C51 to control memory, clock, display and printer. From the experiments, we concluded that the designed equipment has worked successfully and efficiently, and it needs a low electric power, 2.42 Watt

A Tool for Mobile Robotics Research

This paper introduces TeamBots as a tool for mobile robotics research. TeamBots enables researchers to develop robotic control systems and test the control systems in simulation as well as on physical robots. Simulation plays important roles in multi-robot research. Interaction among robots in multi-robot systems can produce interesting phenomena. It is hard to predict the effectiveness of a control system without simulating it in a multi-robot environment. This paper presents a case study and compares it to closely related work. The experiment result shows that even for the same task (i.e. foraging) a control system that performs best in a particular environment may not be the best control system in different environments

Pencarian Rute Optimum Menggunakan Algoritma Genetika

Genetic algorithm can be used to solve optimation problems, such as for finding optimal route, which may be influenced by many internal conditions. In this paper, genetic algorithm was implemented to search optimal route from the start point to the destination point. Genetic algorithm system was designed by using bit string - chromosome representation, thus the mutation used was bit mutation. The selection method used was roulette wheel, elitism and hybrid selection between roulette wheel and elitism. There were two kind of crossover points used - one and two cut point crossover. From the experiments, we could conclude that the genetic algorithm system design worked well and solved the optimation problems

Odor Recognition Dengan Menggunakan Principal Component Analysis Dan Nearest Neighbour Classifier

This paper describes about implementation of principal component analysis method on odor recognition system. There are 15 essences used in this research and each essence has 20 concentrations. Principal Component Analysis (PCA) method was used in this system to reduce the data\u27s dimension. The result of PCA would be input of recognition system. The recognition system used in this research is nearest neighbour method. Experiments were done for testing the designed system. Although the data were reduced until 93,75%, the system could recognize the essences well and achieve a recognition rate of 99.56%

Sistem Pengembangan Kendali Fuzzy Logic Berbasis Mikrokontroler Keluarga Mcs51 (Petrafuz)

This paper presents a Fuzzy Logic Development Tool called PetraFuz which has been developed at Control System Laboratory, Electrical Engineering Department, Petra Christian University. The system consists of a hardware target based on MCS51 microcontroller and a software support running under PC Windows. The system is targeted for developing fuzzy logic based systems. It supports fuzzy logic design, evaluation, assembly language generator and downloading process to the target hardware to perform on-line fuzzy process. Process action and fuzzy parameters could be transferred to PC monitor via RS-232 serial communication, this on-line process parameters is used for fuzzy tuning, i.e. fuzzy if-then rules and fuzzy membership functions. The PetraFuz tool helps very much for Fuzzy system developments, it could reduce development time significantly. The tool could spur the development of fuzzy systems based on microcontroller systems such as fuzzy control systems, fuzzy information processing, etc

Application an Odour Recognition Using Nearest Neighbour Algorithm

This project was undertaken with the aim of developing control techniques and data processing methods to allow a relatively simple electronic nose developed for robotics applications to classify a wide range of odours. The electronic nose used tin oxide gas sensors as the main sensing elements. By modulating the sensor temperature inside the sensors%2C additional information was gathered which helps to identify unknown odours. A simple K-nearest neighbor algorithm was implemented as the basis of a pattern recognition system for recognizing odours presented to the system. Further%2C we considered ways of compressing the stored data and techniques for finding the best match among the trained data using Principal Component Analysis
