Raspberry Pi Home Automation Using Android Application

The project presents a low cost and flexible home control and monitoring system using a Raspberry PI module and a Static Relay, with internet connectivity for accessing and controlling devices and appliances remotely using Smartphone android application. The proposed system does not require a dedicated server PC with respect to similar systems and offers a novel communication protocol to monitor and control the home environment with more than just the switching functionality. To demonstrate the feasibility and effectiveness of this system, devices such as Static relays and a wifi router can be integrated with the home control system.

Buck-Boost Operation Using a Z-Source Inverter

An impedance-source (or impedance-fed) power converter (abbreviated as Z-source) and its control method for implementing dc-to-act, ac-to-dc, ac-to-ac, and dc-to-dc power conversion are presented in this paper. This impedance converter employs a unique impedance network (or circuit) to couple the converter main circuit to the power source, hence provides a unique feature that cannot be obtained in the traditional converters where a capacitor and inductor are used, respectively. The Z-source converter overcomes the conceptual and theoretical barriers and limitations of the usual source converter (known as a V-source converter and I-source converter) and provides a novel power conversion concept. The Z-source concept can be applied to all ac-to-ac, dc-to-ac, dc-to-dc, and ac-to-dc power conversion. To describe the control and operating principal, this paper explains an example: a Z-source inverter for dc-ac power conversion needed in fuel cell applications.Experimental results and simulation are presented to demonstrate the new features.

Detection and Analysis of Network & Application Layer Attacks Using Honey pot With System Security Features

Information security in the sense of private and social interactions has become a top priority in digitalized modern world in parallel to the new technological developments. Many approaches, tools, and expertise are used to provide the information security to the information systems. A honeypot is an active defense system for network security. It is able to trap attacks, record intrusion information about tools and activities of the hacking process, and prevents attacks outbound the compromised system. Integrated with the other security solutions, the honeypot is able to solve many traditional dilemmas. We expatiate key components of data capture and data control in a honeypot and give a classification for honeypot according to security goals and application goals. A honeypot is Java based deception tool having influential services (FTP etc.), it is a “Rule & Anomaly” based intrusion detection engine and a network-based administration and monitoring tool. This paper analysis the attack detector with existing system drawback which presents proposed approach more efficiently. Additional system security features are also added based on accessing the system securely. Features like detection of an intruder based on the timestamp and log-in details are considered. Tracking of the user is based on the system log and other databases pre-defined for secure accessing.

Automation of Lubrication System

In engines, frictional losses are mainly due to slide as Well as rotating parts Engine friction is expressed in terms of frictional power Friction all losses is mainly attributed to the following mechanical losses

• Direct frictional losses
• Pumping losses
• Power loss to drive the components to change and scavenge Power loss to drive other auxiliary components

A good engine design should not the total frictional losses to be more than 30%of energy input in Reciprocating engine. It should be the aim of a good designer to reduce friction and wear of the parts subjected to relative motion. This is achieved by proper lubrication system

1. Direct Frictional Losses:

It is the power absorbed due to the relative motion of different bearing surfaces such as

• Piston rings,
• main bearings,
• Cam shaft bearings etc…

2. The frictional losses are comparatively higher in the reciprocating engine.

3. Pumping Loss For4-stroke engines Considerable amount of energy is spent during the exhaust

Processes. The pumping loss is the net power spent by the engine (piston) on the working medium (gasses) during intake and exhaust strokes. For2-stroke engines this is negligible since the incoming fresh mixture is used to scavenge the exhaust gasses Power Loss to drive the components to change and scavenge 4-strokeengine. In turbo/supercharged engines the intake charge is supplied at A higher pressure than the aspirated engines For this purpose mechanically driven compressor or turbine driven compressor used accordingly the engine is called Supercharged or turbocharged engine.

Space Vector Control Method for PM-BLDC Motor

Several methods have been proposed to eliminate the low-frequency torque pulsations for BLDC motor drives such as Fourier series analysis of current waveforms and either iterative or least-mean-square minimization techniques. Most methods do not consider the flux linkage control, therefore possible high-speed operations are not feasible. In this work, a novel and simple approach to achieve a low-frequency torque ripple-free speed and flux control with maximum efficiency based on dq reference frame similar to the permanent magnet synchronous motor (PMSM) drives is presented. The electrical rotor position is estimated using winding inductance, and the stationary reference frame flux linkages and currents. Moreover, this method also permits to regulate the varying signals. Simple voltage vector selection look-up table is designed to obtain fast torque and flux control. Furthermore, to eliminate the low-frequency torque oscillations, two actual and easily available line-to-line back- EMF constants (kba and kca) according to electrical rotor position are obtained offline and converted to the dq frame equivalents using the new Line-to-Line Park Transformation. Then, they are set up in the look-up table for torque estimation.
