Banyak sekali data seperti data transaksi, data barang, atau lainnya yang terbuang begitu saja setelah tidak digunakan lagi. Namun ternyata data tersebut masih memiliki banyak informasi jika kita bisa mengelolanya dengan baik. Selain itu data yang masih digunakan pun masih sering kita jumpai memiliki struktur yang membinggungkan pembacaannya. Hal itu yang membuat analisis pada data akan mengalami kesungkaran dan membutuhkan waktu yang cukup lama dalam mengambil keputusan atau mencari informasi didalamnya. Dalam sebuah penelitian mengungkapkan bahwa memvisualisasikan data akan lebih mudah dipahami dibandingkan tidak sama sekali. Terdapat banyak cara memvisualisasikan data tersebut, salah satunya dengan menuangkannya dalam bentuk grafik. Descriptive statistic adalah sebuah cara yang bisa digunakan untuk melakukan analisis data dan menampilkannya dengan visual. Dalam visualisasi grafik pun terdapat berbagai tipe seperti ...

However, nowadays, most major applications demand higher efficiency and power density due to various reasons. The previously well-known Si devices, unfortunately, have reached their performance limitation to cover all those requirements. Therefore, Silicon Carbide (SiC) with its unique and astonishing characteristic has gained huge attention, particularly in the power electronics field. Comparing both, SiC presents a remarkable ability to enhance overall system performance and the transition from Si to SiC is crucial. With regard to its importance, this paper provides an overview of the characteristics, advantages, and outstanding capabilities in various application for SiC devices. Furthermore, it is also important to disclose the system design challenges, which are discussed at the end of the paper.

The effects of adsorbate initial concentration (10-100 mg/L), contact time, solution temperature (30-60 °C), solution pH (2-6), isotherms and kinetics of the adsorption systems were evaluated through batch adsorption test. Adsorptions of Cu(II) on all the activated carbons prepared were best represented by the pseudo-second-order kinetic model. From the analysis of variance (ANOVA), the significant factors on each experimental design response were identified. The Cu(II) adsorption uptakes increased with increasing initial concentration and contact time.

Central composite design (CCD) was used to determine the properties of the three preparation variables; activation temperature, activation time and ZnClR 2 R: char impregnation ratio (IR) on RSCAC yield and percentage of Zn (II) removal. Based on the CCD, two quadratic models were developed for both responses. The most influential factor on each experimental design response was identified from the analysis of variance (ANOVA). The optimum conditions obtained for preparing the RSCAC were activation temperature of 797P o P C, activation time 1h and IR of 2.61 resulting in 22.90 % RSCAC yield and 84.12 % Zn (II) removal.

The machine consists of three wheels that have been arranged 120 degrees between each other around the circumference of the ball. The fuzzy logic system automatically generates PWM signals to control wheel angular speed for each motor based on inputs selected by a user. The machine capable of bowling a cricket ball with an error of 0.423 m for the distance along the pitch, y by using gap size reduced by 1.5 cm at wheel speed of 1000 RPM. The result shows the accuracy of machine decreases when the average wheel angular speed increases e.g. the error of slow speed setting is 0.407 m while the error of medium setting is 3.861 m. The differences range for the distance along the pitch, y for vertical and horizontal spin settings is between 1.7 m to 3.2 m.

It is important to detect and identify the source of the PQ problem. This paper presents a voltage variation signals source identification and diagnosis method by determining the average time frequency representation (TFR) phase power of the impedance. The signals focused in this study are the voltage variation signals, which include voltage sag, swell and interruption. The voltage variation signals from different source location (upstream, downstream as well as up and downstream) according to the IEEE Standard 1159 by using the mathematical models. The signals are first analyzed by using the Spectrograms which act as the feature producing tool. Then, the average power TFR of phase domain of each signal is calculated and tabulated. Finally, the performance of the method is identified by using support vector machine (SVM) and k-nearest neighbor (kNN). The results show that this method is an effective and suitable technique for identifying the source of voltage variation.

The national team is under the supervision of the Malaysia Cricket Association (MCA). Currently, most the player training is done manually. Therefore, this study focuses on the development of the cricket bowling machine as a mean to ease the training session as well as analyzing the machine’s performance through experimental data. Two machines have been designed and fabricated to analyze the difference in performance between a single rotating wheel mechanism and two counter rotating wheel mechanism to propel the ball. The ball speed ratio is based on the linear wheel speed. As the wheel speed increases, the single-wheel ball speed ratio ranged from 47 to 50 % with a gradient of −0.0032. On the other hand, the two-wheel ball speed ratio ranged from 68 to 95 % with a gradient of −0.0245.
