Abstract

One indicator of a person's health is signal pattern of electrocardiogram (ECG). ECG signals are generated by the heart's electrical activity. ECG signal pattern is recognized by physicians to determine a patient's heart health. Some of the techniques were developed by researchers to automatically recognize the ECG signal. One of the most popular techniques is wavelet transform. In this study, two wavelet packet decomposition schemes for ECG signal recognition are compared to find the best one. The first scheme generates 32 features while the second scheme generates 15 features. Accuracy testing shows that the first scheme produce the best average accuracy of 94.67%, better than the second scheme. Using features selection on the first scheme, four dominant features that produce higher accuracy than using 32 features are obtained. These results indicate that the first scheme is better than the second scheme for ECG signal recognition using wavelet packet decomposition.

Abstract

In the higher frequency range, the wall-thickness causes more effects to the characteristic of slotted waveguide antenna. This paper presents numerical analysis of slotted waveguide antenna by incorporating the wall-thickness using finite element method for inner part of slot and boundary element method for outer or surface part. By using the field equivalent principle, the computation can be done only at the region of cut waveguide wall. The solution of those methods are employed to calculate the electric field along the slot surface and further use to calculate the equivalent network parameters of slot antenna. The results show the agreement to the published numerical and measurement results in the references.

Abstract

One way in recognizing mechanical faults of electrical machines is using the vibration signals. This paper studies the recognition of mechanical faults of electrical machines which have faulty bearing, faulty impeller, and faulty foot valve. Electrical machines studied in this paper are household water pumps. The recognition of mechanical faults is conducted using the vibration signals at the frequency domain at various frequency resolution. The recognition method used is template matching for pattern classes. Euclidean distance function is used in this template matching. Based on the results, the highest recognition rate of 100% is optimally obtained using the vibration signal at frequency resolution of 5,9 Hz, and the number of 5 samples/classes in the water pump database. The 5,9 Hz frequency resolution was obtained using a 256 point FFT, where the number of 128 FFT coefficients are used as the feature extraction.

Abstract

This research explores a detection of finger’s movement using Burg’s Power Spectral Density (PSD) as features vector. EEG signal is recorded using sampling frequency of 1000 Hz. Analysis of the signal is conducted by dividing signal into three segments; 1000 ms, 500 ms and 250 ms. Common Average Reference (CAR) and Support Vector Machine (SVM) are used in features extraction and pattern recognition. The result shows that the system can classify the finger’s movement with accuracy of about ±65,37% in 1000 ms of signal length.

Abstract

Paper impregnated oil (paper-oil insulation) is used as insulation material in transformer. The water in transformer appears as a consequence of oxidation process of the paper-oil system and atmospheric air penetration into the tank. High voltage testing is used to test paper-oil insulation with different water content to examine its breakdown voltage. Three conditions were used in this research, which are initial condition, the condition after heating up to 700C, and the condition after cooling down at room temperature for 2 x 24 hour. The result of high voltage tests shows that the water content can decrease the breakdown voltage and the dielectric strength of paper-oil insulation. The heating-cooling process reduces the water content of oil insulation and therefore increases the breakdown voltage and dielectric strength of paper-oil insulation.

Abstract

This research builds a fitness equipment Lat Pull Down which is modified to produce alternative energy. This tool works by pulling a lever connected to a gearbox. Rotor and generator are connected to the gearbox and will rotate with angular velocity at about 22 rad/s, thus, can generate electromotive force of about 202 V. This AC voltage will be converted by a full wave rectifier using Schottky diodes into 19,8 VDC. An electronic switch, then, will automatically connect the DC voltage, which is still fluctuative, to either an LM2577 or LM2576 chip that will increase or decrease the voltage, respectively, into a stable voltage of 13,8 V. The energy will be stored in the 12 V accumulator and can be used as an energy source for the 2,5 W LED and microcontroller-based guidance system. This system can generate energy up to 2,367 Wh each day.

Abstract

Library services of STIKOM Surabaya in returncollection is not optimal since the return time is limited to the business hours. The returning process also takes long time for barcode reading speed is longer than RFID and fines payment must be made directly at officer, causing queues for other members. This study aims to create prototype and collection return application that makes return process easier, faster, and more flexible in time and place. RFID tag was attached to acollection. The RFID reader located on the prototype was used to detect the collection return data. The data was checked at Library Information System to obtain borrowing status. If borrowing status is valid, then green light is on and if not valid, then red light is on. After the light turned green, the collectionreturn data was stored in the protype memory as backup.Besides, the return data was sent to the collection return application to be processed of return actual date, fines calculation, and time determination of rejected borrow. Experimental results show that the prototype of RFID reader equipped with a mechanism light has been successfully integrated with the collection return application module. The application can also perform the return process in changes ofreturn collection realization date, fines calculation, and time determination of rejected borrow.
