K. Raghavi
Transport discovery utilizing great determination remote detecting pictures is a hot research theme in both military and nonmilitary personnel applications. In this paper, another technique for identification of boats docked in a harbor was proposed, in which, Harris corner identifier consolidated with nearby striking locale examination were utilized to extricate the important sharp-calculated element identified with the fore piece of a ship in satellite pictures. This technique can decide the course of the ship when the ship is distinguished. The aftereffects of tests on a few great determination remote detecting images confirmed the viability of the proposed strategy.

Encryption Techniques and Wireless Power Transfer Schemes

10.11591/ijeecs.v9.i1.pp183-190
Nur Hazwani Hussin
Wireless power transfer (WPT) is one of the most useful ways to transfer power. Based on power transfer distances, the WPT system can be divided into three categories, namely, near, medium, and far fields. Inductive coupling and capacitive coupling contactless techniques are used in the near-field WPT. Magnetic resonant coupling technique is used in the medium-field WPT. Electromagnetic radiation is used in the far-field WPT. This paper reviews the techniques used in WPT. In addition, energy encryption plays a major role in ensuring that power is transferred to the true receiver. Therefore, this paper reviews the energy encryption techniques in WPT. A comparison between different techniques shows that the distance, efficiency, and number of receivers are the main factors in selecting the suitable energy encryption technique.

A PV FED Three Phase Switched Z-source Multi Level Inverter for Induction Motor Drives

10.11591/ijeecs.v9.i1.pp24-28
Sinu KJ , G. Ranganathan
Generally induction motor drives posses higher harmonic contents in line voltage and current due to high switching frequency used in inverters. Conventional induction motor drives employ two level voltage source inverters which has THD in level of 50%. This paper presents a switched z-source multilevel inverter which has voltage boosting capability and has lesser THD level in comparison with conventional two level voltage source inverters. This drive is fed from a photo voltaic source because of its voltage boosting capability. A single phase five level switched z-source inverter is initially designed and considered as single cell and three such cells are created for powering three phase induction motor. The proposed three cell PV source switched z-source multilevel inverter for three phase induction motor is simulated in MATLAB/Simulink software to verify merits of proposed IM drive

Identifying the Breakdown Voltages of Vegetable Oils with Silicone Carbide Nanoparticle Additive as Insulating Oil for Transformers

10.11591/ijeecs.v9.i1.pp170-176
Muhammad bin Yahya , Nurul Aifaa Najihah binti Maliki
This paper discusses on the breakdown voltage of vegetable oils with nanoparticles added to be used as insulating oil for transformers. Raw samples of Palm Oil (PO) and Coconut Oil (CO) were used in this research. Different percentages of silicone carbide (SiC) nanoparticles was added into the samples of the vegetable oils. The different parameters of the vegetable oil mixtures were investigated through the breakdown voltage tests to analyse the effect of the additive on the dielectric strength of the oils. The performance of insulating oils varies according to the percentage of nanoparticles added through viscosity test and partial discharge (PD) measurement. The initial results for vegetable oils showed that the percentage of additives influenced the value of breakdown voltage of the oils highly. Furthermore, the result shows that PD measured became very low after the addition of silicone carbide nanoparticles.

Patel Kalpana Dhanji , Santhosh Kumar Singh
Image fusion is the process of combining relevant information from two or more images into a single image. The resulting image contains more information as compared to individual images. In this system, we are proposing a new image fusion method by using a technique called framelet transform. This method consists of two phases; First is the frame separation where the pre-processing and Selection of frames for both the images occurs and the second phase is the Frame fusion that is done by inverse framelet transform method is done from which a fused output images will be formed that will be containing both the information of the input images (CT & MRI images).

10.11591/ijeecs.v9.i1.pp118-122
K. Hema , Muralidharan Muralidharan
In this paper, we proposed to design a next-generation auto theft prevention system by adding significant enhancements and modernizing the existing security features. As vehicles turn out to be more refined, vehicle security frameworks must be more grounded than at any other time. A current vehicle uses remote keyless passage framework and Immobilizer framework as the primary weaponry against vehicle robbery. These structures avoid unapproved access of the vehicle to a particular degree, however, are not a secure one. Because of the straightforward and imperfect nature of these security frameworks, auto burglary occurrences worldwide are on the ascent. This venture needs a low power microcontroller however with elite prerequisites. LPC11C14 from NXP Semiconductors addresses these issues and in this manner picked as the primary MCU. It is an ultra-low-power ARM Cortex-M0 based microcontroller that can run up to 50MHz. It has 32KB of Flash memory and 8KB RAM.

Non-contact Heart Rate Monitoring Analysis from Various Distances with different Face Regions

10.11591/ijece.v7i6.pp3030-3036
Norwahidah Ibrahim , Razali Tomari , Wan Nurshazwani Wan Zakaria , Nurmiza Othman
Heart rate (HR) is one of vital biomedical signals for medical diagnosis. Previously, conventional camera is proven to be able to detect small changes in the skin due to the cardiac activity and can be used to measure the HR. However, most of the previous systems operate on near distance mode with a single face patch, thus the feasibility of the remote heart rate for various distances remains vague. This paper tackles this issue by analyzing an optimal framework that capable to works under the mentioned issues. Initially, plausible face landmarks are estimated by employing cascaded of regression mechanism. Next, the region of interest (ROI) was constructed from the landmarks in a face location where non rigid motion is minimal. From the ROI, temporal photoplethysmograph (PPG) signal is calculated based on the average green pixels intensity and environmental illumination is separated using Independent Component Analysis (ICA) filter. Eventually, the PPG signal is further processed using series of temporal filter to exclude frequencies outside the range of interest prior to estimate the HR. As a conclusion, the HR can be detected up to 5 meters range with 94% accuracy using lower part of face region.
