Smart Data Recognition System For Seven Segment LED Display
Get PDFThe automatic data capturing system provides an alternative and effective way of data collection instead of manual data collection in the laboratory, especially for experiments that need to be carried out for a long period. It can solve common mistakes made by humans, like misreading or mistyping data. Thus, a new smart data recognition system for a seven-segment LED display is developed to sort the whole process of data collection to become more systematic and accurate. An image is captured and saved automatically in an image file, and then it is processed through MATLAB software to identify the digits displayed on the LED display. Once the image is preprocessed, analyzed, and recognized, the final output values obtained are transferred to an existing Excel file for a further process according to the user’s requirement. From the results obtained, it was proven that binary thresholding is the best preprocessing method, and the brightness of the image should be set to ‘0’ for better recognition output

The Efficiency of Dyes Sensitized Solar Cells Using Different Sensitized Dyes
Get PDFManufacturing techniques of solar cell have been developed rapidly since their first appearance. Dyes sensitized solar cell (DSSC) is a modern technique of solar cell .It optimized by their low manufacturing cost and the high power conversion. In this paper three of DSSC were fabricated using three different sensitized dyes Cumarin 500 , Alcian Blue 8GX and Bangal Ross B Sodium Salt. The absorbance of each DSSC was determined by Ultraviolet- visible spectrometer. The short circuit voltage and current were measured for each sample to determine which of the dyes has the best efficiency of power conversion. The results also obtained the fill factor for each of DSSCS. The results showed the fill factor and the bandgap of each sample. The voltage and current results reflect that Bangal Ross has the highest efficient of the other dyes
Machine Learning Shrewd Approach For An Imbalanced Dataset Conversion Samples
Get PDFThe imbalance data applies to at least one of the classes, which are typically exceeded by the other ones. The Machine Learning Algorithm (Classifier) trained with an imbalance dataset predicts the majority class (frequently occurring) more than the other minority classes (rarely occurring). Training with an imbalance dataset poses challenges for classifiers; however, applying suitable techniques for reducing class imbalance issues can enhance the classifier’s performance. We take an imbalanced dataset from an educational context. Initially, all shortcomings regarding classification of imbalanced dataset have been examined. After that, we apply data-level algorithms for class balancing and compare the performance of classifiers. The performance of the classifier is measured using the underlying information in their confusion matrices such as accuracy, precision, recall, and f-measure. It shows that classification with an imbalance dataset may produce higher accuracy but low precision and recall for the minority class. The analysis confirms that both undersampling and oversampling are effective for balancing datasets, however, oversampling dominates.
Design of a Broadband Microstrip Array Antenna for 5G Application
Get PDFThis paper presented a study that analyses the enhancement of high gain microstrip array antenna for 5G applications operating at 28 GHz designed to meet the ETSI standardization. It is expected that the gain must be high at high operating frequency so that it can compensate the propagation path loss. The objective of this study was to design a 16-element microstrip array antenna located at the top of antenna as a rectangular patch. Aiming to achieve low loss and high antenna efficiency, the material used for the proposed design was Roger 5880 materials with the permittivity of 2.2 and thickness of 0.25. Initially, a rectangular microstrip array antenna with 4 elements was designed. After analyzing the outcomes of antenna features such as reflected loss, efficiency and antenna gain, the 4 elements array were transformed into 8 elements array. To achieve high gain, it was then transformed into 16 elements array. Based on EM analysis using CST software, it was found that the proposed antenna has high efficiencies and high gain of 18.5 at 28 GHz operating frequency
FPGA-Assisted Assertion-Based Verification Platform
Get PDFIn this paper, field programmable gate array (FPGA)-assisted verification platform is devised to enhance the assertion-based verification methodology to address the issues of high demand of integrated circuit with the advanced features to be delivered to market within tight Time-To-Market. The concept of SystemVerilog Assertion (SVA) checker generator is introduced to translate non-synthesizable verification coding into hardware so-called assertion checker in Verilog. A lookup table, which comprises of SVA operators mapped to their corresponding synthesizable Verilog coding was developed to generate assertion checker, which produces a single bit 1 when the assertion fails. Collection module implemented using a memory block and an arbiter was devised to be simple and fast enough to collect assertion results from the assertion checker. Since assertion checker can produce assertion result at any time, an arbiter is required to act as an interface between assertion checker and collection module. Case studies have been conducted on the proof-of-concept designs, which are the firstin-first-out (FIFO), up-down counter and Context Adaptive Variable Length Coding (CAVLC) to evaluate the effectiveness of the proposed FPGA-assisted verification platform. In the case studies, we have shown that the proposed FPGA-assisted verification platform works correctly. Besides, we also evaluated the method in area utilizations (ALMs). It has been proven that simulation-based verification time can be reduced for as much as 50% for complexity of VLSI design. Thus, implementing assertions using hardware such as FPGA becomes a solution to alleviate issue of long simulation time
Steering Angle Control of Rack Steering Vehicle using Antiwindup-PI-Control
Get PDFThe precision of the steering in a vehicle is one of the issues that need to be tackled for safety and energy efficiencies, especially in the motion at the cornering or turning. The issue is crucial especially for vehicles with a non-holonomic system such as rack steering vehicles, as it is more prone towards high collisions to the peer walls or off-road incidents due to the inertia factor. Therefore, this has taken the initiative to propose a steering precision control strategy using the proportional and integral (PI) control that considers the Rack Steering Vehicle (RSV) dynamics and its friction as well as aerodynamics disturbances. The control objective is emphasized on steering input precision in which steering feedback response is derived from the vehicle dynamics with disturbances. The RSV model and the antiwindup-PI control are model and simulated in order to verify the proposed control strategy for the RSV system. The results show that with small fine tunes on the antiwindup-PI controller, the steering input is controlled precisely with a very minor steady-state error if compare to the single PI controller. Regarding vehicle axial velocities, both horizontal (X-axis) and vertical (Y-axis) velocities are controllable without radical fluctuated as well as oscillation speed if compare to the RSV with PI controller
