Abstract

Face recognition in pictures or videos is trending research area in the field of biometric system and application. In so many it is very easy to see the video surveillance cameras and camcorders for security and safety. It is very widespread that it has been recognized that face recognition plays an important role in the monitoring system as it does not require the subject of cooperation. The real benefits of face-to-face recognition of other biometric technologies are unique and responsive. Just like humans, the face is a very dynamic aspect of the object, making face detection a problem of computer vision. In this sense, identifying precision and speed is a major issue. The purpose of this paper is to evaluate the detection of different faces. The identification method provides a complete solution for recognizing front images and better recognition, a better response rate is the first step in video surveillance............

International Journal of Computational Engineering Research, Volume 08 ~ Issue 10 (October – 2018)

Abstract

This paper includes modal analysis and harmonic analysis studies for a bolted joint test rig. Machinery vibration problems, e.g. bolt loosening, may get more severe if the operational frequency of the systems matches with any of the natural frequencies of the system. Such problems can be controlled by carrying out modal and harmonic analysis of the system. The test rig considered in this work is a multibody system (MBS) and includes eight components in it. Various components of the system have been modelled in the CAD environment. These components are then assembled to get the overall CAD model of the experimental bolted joint test rig. Modal analysis of flexible components of the system has been carried out. This is followed by modal and harmonic analysis of the CAD model of the experimental test rig. Modal analysis helps in identifying resonance regions. Such primary analysis of system plays important role in studying loosening of bolted joints as well as in finding out fatigue strength of the dynamic systems.

Keywords: Bolted Joints, Natural Frequency, Modal Analysis, Harmonic Analysis.

Abstract

EEG signals are generally measured on multiple locations for Brain Computer Interface (BCI) application as well as other modalities. This high number of channel count increases complexity of algorithm additionally gives discomfort to patient. In order to resolve both problems we have proposed an approach based on higher order statistics like kurtosis, Skewness and moment. Based on them we find channels of highest deviation during onset of activity. The selected channels classification accuracy compared with Linear Discriminant Analysis, Artificial Neural Network and Support Vector Machine on publically available database on physionet website.

Abstract

Nitrogen doped titanium dioxide (NTiO2) thin films were deposited on glass substrates using dc reactive magnetron sputtering technique and their composition, crystalline structure, surface morphology and optical properties were studied as a function of substrate bias voltage. The films exhibited amorphous structure irrespective of the substrate bias voltage. From the SEM images, grain size of the films increases with increasing the substrate bias voltage. The optical band gap of the films was narrowing from 3.07 to 3.02 eV with increasing the substrate bias voltage. The wettability of the films increases with substrate bias voltage.

International Journal of Computational Engineering Research, Volume 08 ~ Issue 10 (October – 2018)

Abstract

In the present study, thermal analysis of a linear parabolic solar collector has been studied by using circular and semicircularabsorbertube. Computational fluid dynamics analysis has been carried out by using non uniform heat flux distributions on the surface of the absorber tube. The non uniform heat flux distribution on the absorber tube is calculated by using Monte Carlo ray tracing method in the SolTrace software. The results are presented for the conventionalabsorber tube receiver and semicircularabsorber tube receiver, for the range of inlet temperature 300K to 650K and Reynolds numbers 0.25x105 to 2.82 x105. The maximum gain in the collector efficiency of the parabolic trough collector is found to be 5% at the Reynolds number equal to 25000.

Abstract

Cloud computing is an emerging internet based computing technology. Increased demand of computing resources has raised the need to outsource the resources and made cloud most enticing technology nowadays. As it is internet based technology so the challenges faced by internet based technologies are the major challenges of cloud computing. Security and privacy are major challenges due to which organizations are not migrating data to cloud with full confidence. 128 bit Advanced Encryption Standard (AES) is used for increase data security and confidentiality. Due to some drawbacks of AES several algorithm has tried to modify the static nature of S-box. An attempt has been made in this paper to modify AES. This paper highlights security threats in cloud and proposed an enhanced AES algorithm to migrate data to cloud securely.

International Journal of Computational Engineering Research, Volume 08 ~ Issue 10 (October – 2018)

Abstract

Mobile device structure is organised in a layered architecture from electronic components to application user interface. Based on various functionalities, the mobile devices are separated into multiple layers. Each layer has well defined boundaries and interacts with each other using certain protocols. The layered separation helps the devices to segregate the functionalities in stabilized and secured manner. Depending on manufacture, the components in each layer change. Most of the mobile devices are follow a standard architecture but the components and methodologies used in each layer have differences. The degree of smoothness between the layers directly proportionate with user friendliness of the mobile device.

Abstract

Segmentation of brain tissues is one important process prior to many analysis and visualization tasks for Magnetic Resonance (MR) images. Edge is one of the important characteristic features used in many image segmentation techniques for brain tissue segmentation in MR image. Sobel- Feldman approximation is technique used for detection of edges in any image. Unfortunately, MR images always contain significant amount of noise caused by operator performance, equipment and the environment. This noise can lead to major inaccuracies in edge detection process and hence in segmentation result. We conduct the research in measuring the performance of Sobel-Feldman approximation for edge detection in different noise level for single-channel MR image.............

International Journal of Computational Engineering Research, Volume 08 ~ Issue 10 (October – 2018)

Abstract

Objective of highway agencies is to develop rational and defensible specifications for the acceptance of highway materials and transportation structures. Such specifications are often coupled with a pay schedule that rewards higher and penalizes lower quality levels. This study had as objective the development of a methodology examining the production population characteristics and assessing the effectiveness of pay schedules to award appropriate levels of monetary rewards for desired target quality levels. The proposed approach uses the distribution of production quality to generate alternative lots through Monte Carlo simulation and examine the impact on pay factors (PF). Then, the probability of receiving a certain level of PF is estimated for assessing the rationality of the pay schedule in relation to the achieved quality..........
