Images contain information based on their color intensity. By observing the degree of color intensity difference between two pixels or more, it can be determined an edge of image. The problem encountered is that if the color intensity difference between the pixels that is assumed as an edge is not significant, so the edge determination of image becomes unclear. An objective function can be used for calculating the magnitude of 4 direction values (horizontal, vertical, and 2 diagonals) of a pixel in the image. The result of this calculation can be used as feature of image texture. By analyzing the characteristics of image texture features, they can be grouped to determine whether the pixels are included in the category of background, edge, or noise. In this research, the image texture features clustering are done by implementing Fuzzy C Means algorithm based on the data distribution of mean and standard deviation values of each 4 magnitude direction values of a pixel which have been calculated based on the objective function. The value of the cluster centers obtained from the data clustering is further ranked to know their differences. Based on analysis, this method can distinguish 3 image texture features clearly (background, edge, noise). Therefore it can be concluded that cluster center grouping with the largest mean value can be used to form an edge of the image.

The use of radar technology as a defense equipment in the maritime territory has been widely applied in almost all regions of Indonesia. FMCW radar displays the raw data streamed from the DSP device. It is often observed that the data plotting results formed in an incomplete echo image because of the non-continuous pixels between the pixel data with the surrounding. This is caused by the execution time of the plotting process could not accommodate the changes of subsequent data. There are two ways to overcome these problems, by upgrading hardware capabilities, and perform image processing that stored in the buffer before it is displayed on the screen. This paper describes the design of morphological dilation which is applied in the plan position indicator (PPI) radar to improve the quality of radar image so that it can improve the quality of the extraction object in the research that has been done to reduce the loss of the object when the object tracking process takes place.

With the development of large data age, Convolutional neural networks (CNNs) with more hidden layers have more complex network structure and more powerful feature learning and feature expression abilities than traditional machine learning methods. The convolution neural network model trained by the deep learning algorithm has made remarkable achievements in many large-scale identification tasks in the field of computer vision since its introduction. This paper first introduces the rise and development of deep learning and convolution neural network, and summarizes the basic model structure, convolution feature extraction and pooling operation of convolution neural network. Then, the research status and development trend of convolution neural network model based on deep learning in image classification are reviewed, which is mainly introduced from the aspects of typical network structure construction, training method and performance. Finally, some problems in the current research are briefly summarized and discussed, and the new direction of future development is forecasted.

In this paper, we discuss the implementation of a digital pre-distorter for wideband wireless applications using Legendre polynomials as the orthogonal polynomial basis. The implementation discusses a multicarrier configuration using a wideband amplifier. Structures based on polynomial functions are widely used for both power amplifiers (PA's) and predistorters. Higher non-linear orders in the structure tend to increase the numerical stability. Pre-distorters based on orthogonal basis which is discussed based on orthogonal polynomials. The orthogonal polynomial basis discussed is robust and stable and meets the spectral emissions requirements with regards to the adjacent channel power ratio (ACPR).

Wireless electrical transmission technology is the diffusion of power energy without using any physical support. It is useful to transfer power to those places where it is difficult to transmit electricity using conventional wires. In this research paper, we designed and realized a wireless lighting technology using the fundamentals of electromagnetic radiation. It is shown that than of 10 W can be radiation between the transmitter coil (Tx) and receiver (Rx) and active the LED lamp 20 W, though table thickness 50 mm. Electromagnetic radiation has a short range. However, wireless transmission range can be increased by applying high power amplifier stage and with high magnetic resonance. In this paper, parameters and design of electromagnetic coupling transmitter and receiver components are proposed. So, the proposed electronic device takes account all parameters above to deliver sufficient energy to active LED lamp 20 W.

Public, demand for wireless communications in recent years is increasing very rapidly so that a reliable and cheap telecommunication facilities make people become easier to communicate. Therefore, the information can be transmitted from communication voice began to change towards data and multimedia. But the availability of frequency spectrum is inversely proportional to the needs of society. To meet the needs of the high community of wireless telecommunications facilities, then the greater the bandwidth required. However, most of the frequency spectrum already allocated a user or a particular service. Still sparse availability of this type of antenna that is capable of supporting cognitive radio technology because of low bandwidth. In studies using an electromagnetic simulator to design and simulate ultra wide band (UWB) microstrip antenna with a coplanar waveguide for Cognitive Radio application that can be used at a frequency of 800–2400 MHz. Results of the antenna design work of frequency 800–2400 MHz with omnidirectional radiation pattern; gain > 3dBic; input impedance = 50 Ω and VSWR < 2.0.

In this paper we report the consistency in controlling the Q-factor value ranging from 1000 to 80,000 together with good free spectral range (FSR) control between the resonance frequencies of between 30 nm to 62 nm of a long cavity based on SOI. The cavities that were considered in this paper ranged from 2 pm to 6 pm in length. The Q-factors for each resonance obtained for that particular extended cavity were measured in different occasion which has 5% variation in the Q- value over a period of times. We expect that the removal of Silica cladding underneath the silicon waveguide will enhance the Q- value due to better optical confinement within the waveguide.

Microwave wireless and optical fiber technologies are widely used for several applications in communication, sensing, imaging, and so on. We propose an electro-optic (EO) modulator with a planar stripline feed to a gap-embedded patch-antenna for hybrid uplinks to an optical fiber and microwave wireless networks. The proposed device is designed on an EO crystal with simple and compact structure. The gap-embedded patch-antenna on the EO modulator can be operated for optical modulation to the optical fiber network. The proposed device can be also operated for microwave transmission to the air or wireless networks. Characteristic and analysis of the designed device for optical modulation and wireless microwave transmission are reported and discussed.
