Development of a Secured Door Lock System Based on Face Recognition using Raspberry Pi and GSM Module

Security is an important part of everyday life. The main aim of the system is to develop a secured door lock system. The system consists of three sections. The first section is the face recognition system that is based on Haar like features detection method and Local Binary Pattern LBP recognition algorithm. The second section is the password security system. And the last section is the alert system through GSM module. The system is composed by the combination of face recognition security system, password security system and the alert system through the GSM module. In this system, the iteration used in face recognition system is reduced by using Local Binary Pattern LBP algorithm. In saving time, the processing time of this system, therefore, is better than that of the normal system.

Risk Assessment Model and its Integration into an Established Test Process

In industry, testing has to be performed under severe pressure due to limited resources. Risk based testing which uses risks to guide the test process is applied to allocate resources and to reduce product risks. Risk assessment, i.e., risk identi cation, analysis and evaluation, determines the signi cance of the risk values assigned to tests and therefore the quality of the overall risk based test process. In this paper we provide a risk assessment model and its integration into an established test process. This framework is derived on the basis of best practices extracted from published risk based testing approaches and applied to an industrial test process.

Lateral Stability Improvement for Elevated Steel Water Storage Reservoir in Severe Wind and Earthquake Zone using Etabs

Elevated water tanks are most commonly used in storing of water to supply at a certain height for pressurizing in the water distribution system for various purposes. A major irregularity is along the height of the structure due to heavy water mass on the top and phenomenon of hydrodynamic interaction between the fluid and the walls of the tanks, hence the effect on the whole structure, with the accelerating in horizontal causing the sloshing effect, which cannot be neglected because of the various research done on the elevated tank, which showed issues which a significant problems in terms of modeling, stability and design of the structure. So, In the present study, the attempts are made to study the behavior of hydrodynamic effect Impact of liquid sloshing in water full and empty condition on elevated steel water storage reservoir in sever wind and earthquakes zone of India. The analysis is done with Equivalent static method, Response spectrum method and also P Delta effect with different combination of lateral and horizontal braced supporting frame systems. For modeling and analysis were performed using Etabs Ultimate 17.0.1 Finite element software. The results of the analysis, in terms of Displacement and Time period, are obtained. For a square tank capacity of 150 m3. Frame with wall supported on cantilever staging and X type diagonal lateral bracing with intermediate horizontal bracing is performed very well and it is most efficient in terms of material used for construction. Saving steel material in horizontal tie beams, Lateral bracing, and intermediate horizontal bracing. Time period decreased for the frame with intermediate horizontal bracing, hence increasing the overall stiffness of the frame and making the frame more stable in terms of displacement.

Study on the Properties of Natural Soil Stabilized with Various Percentages of Lime Contents

This paper presents study of the stabilization of natural soil with lime. Firstly, Soil samples from Madaya Township are collected and several laboratory tests are carried out to determine the characteristics and engineering properties of the studied soil. Then experimental tests have been conducted for the determination of Atterberg limits and California Bearing Ratio CBR values. The studied soil contains more than 50 of silt clay fraction. So, the studied soil is stabilized with lime contents selected as 5 and 10 by weight of natural soil at maximum dry density. When soil samples are mixed with lime, the values of liquid limit, plasticity index and CBR values are changed. These changes are decreased in swelling and shrinking potential of the soil, decreased in the settlement of the pavements, increase in workability and increase in the bearing capacity of the soils. In this study, the CBR values of soil lime mixtures are 71.4 and 64.4 higher than that of studied soil. It can be seen that the CBR value of lime 5 is greater than lime 10 and natural soil. So, soil lime mixture with lime 5 content is suiTablefor soil stabilization of the street, road and highway.

Comparative Analysis of Efficient Designs of D Latch using 32nm CMOS Technology

In this paper we have proposed various efficient designs of low power D latch using 32nm CMOS technology. We have designed and simulated these circuits in HSpice simulation tool. In this simulation we have modified W L ratio of each transistor in each circuit. We have taken power supply of 0.9V. We have calculated average power consumed propagation delay and power delay product.

Consideration of Three Phase Faults on Transmission Line with Distance Protection

In a modern power system, electrical energy from the generating station is delivered to the consumers through a network of transmission and distribution. Transmission lines are also important elements of electric power system and require attention of protecting for safety against the possible faults occurring on them. The detection of a fault and disconnection of a faulty section or apparatus can be achieved by using fuses or relays in conjunction with circuit breakers. Distance relay has the ability to detect a fault within a distance along a transmission line or cable from its location. Distance relay protection is the most widely used in case of high voltage and extra high voltage in the transmission line. In this paper discussion about how to protect the long transmission line with distance relay.
