This paper proposes features that are extracted solely from Freeman Chain Code (FCC) for handwritten character recognition purpose. Targeting alphanumeric Roman characters, its structure constructed from the chain code is disassembled into segments and landmarks, before each segment is traced to detect predefined line shapes. Two types of feature vectors, sequentially connected shape identifiers and concurrently used shape occurrence counts and size ratios along with landmark positions, are produced from the tracing. Effectiveness of the proposed feature vectors are tested with Hidden Markov Model (HMM) for sequential, while concurrent feature vector is with Artificial Neural Network (ANN), showing mediocre results where only digit character class achieves the highest 80% classification accuracy.

This paper proposes a new design of high-gain beam-steerable dipole antenna array for fifth generation (5G) smartphone applications. This 5G antenna was designed used RT Duroid 5880 substrate with dimension size 60×130×0.787 mm3. It consists of 10 dipole antenna elements to a linear array form that smartphone can be configured at the top portion of a smartphone PCB. Simulated show results the proposed 5G antenna is working in the frequency range of 34.875–42.000 GHz, providing 7.125 GHz or 18.75 % of impedance bandwidth. The proposed of 5G antenna reaches gain 13 dBi, and produces a 3 dimensional beam steerable characteristics in the entire operational frequency. The proposed antenna also has mutual coupling characteristic between its elements of less than -10 dB.

A Rectangular Dielectric Resonator (DRA) has been designed and investigated at 26GHz of frequency using different feeding techniques. The Probe feed method has achieved a Percentage bandwidth of 14.73. An aperture coupled DRA and stripline fed DRA also have achieved wideband, which can be used for 5G Wireless Applications. The microstrip fed DRA have achieved the highest gain value of 7.10 dBi. The design parameters of the dielectric resonator are also optimized and are shown in this paper. The performance of the DRA has been analyzed by using parameters as return loss, impedance match, bandwidth and gain for three different feeding techniques.

The operating speed of a digital signal and systems are in several GHz range to initiate faster response. Due to this high frequency and operating speed of the signals more and more signal integrity related issues may arise and these issues has to be solved for the better performance of the system. Now a day’s integration and miniaturization of digital devices of printed circuit boards (PCBs) are the key features in high speed technology. The printed circuit boards traces are crowded in the design and creates magnetic coupling interference between them. These traces are considered as transmission lines which carrying signal and power between two more points. When current flows through the traces a magnetic field is always set up and interact with the neighboring conductor due to close proximity. The magnetic coupling is mutual and not possible to avoid it. In the result the signal gets affected which degrades the performance of the system to great extent. So, it is necessary to reduce the effect of mutual coupling to improve the performance of the system for its better signal integrity. The mitigation of mutual coupling effect is analyzed and suppression is achieved using metamaterial based complementary split-ring resonators. A new design of double-slit CSRR is used to reduce the crosstalk which is due to coupling. The FEXT analysis is carried out for the frequency range of 5 GHz to 10 GHz.

The Internet of Things (IoT) has evolved and penetrated to our live since the end of the last century. Nowadays, many devices for any purpose are connected through the Internet. A smart node, in smart campus environment, can detect an availability of an open parking space by calculating the vehicle that enters or outs from the space. The node applies a background subtraction method, which is deployed in IoT architecture. The Gaussian Mixture Model (GMM) is utilized to determine foreground and background image, in order to detect a moving object at an open area. Furthermore, the node can discriminate the type of vehicle with a high accuracy. The result of vehicle type classification is transmitted by the node through the Internet, and then it is saved to the data server. We observe the designed system succeeds delivering a good performance in terms of average accuracy determining car and motorcycle are 93.47% and 91.73%, respectively.

The National Amil-Zakat Agency (Baznas) in Pekanbaru has the function to collect and distribute zakat in Pekanbaru city. Baznas Pekanbaru should be able to determine Mustahik properly. Mustahik is a person eligible to receive zakat. The Baznas committee interviews and observes every Mustahik candidates to decide whom could be receive the zakat. Current Mustahik determination process could lead to be subjective assessment, due to large number of zakat recipient applicants and the complexity of rules in determining a Mustahik. Therefore, this study utilize artificial intelligence in determining Mustahik. The Bayesian Network method is appropriate to apply as an inference engine. Based on the experimental results, we found that Bayesian network produces a good accuracy 93.24% and effective to use in data set have an uneven class distribution. In addition, based on experiments by setting an alpha estimator’s values, at 0.6 to 1.0 can increase the accuracy of a Bayesian Network to 95.95%.

Adolescent is a transition from child to adulthood. In this phase, many teenagers do not know their learning style, whether auditory, visual or kinesthetic. To analyze the way of adolescent learning required counseling from a psychologist. Furthermore, To maintain the objectivity of advice, technology can help the psychologists to build an expert system. This research discussed the expert system to determine of adolescent learning styles based on expert knowledge by comparing the effectiveness of demster-Shafer and certainty factor by referring at the process of calculation or processed data effectively and generating accurate confidence values. The results can be a reference for psychologists in determining learning styles so that it can be developed into an expert system application-based technology.
