Let's read! We will often find out this sentence everywhere. When still being a kid, mom used to order us to always read, so did the teacher. Some books are fully read in a week and we need the obligation to support reading. What about now? Do you still love reading? Is reading only for you who have obligation? Absolutely not! We here offer you a new book enPDFd the perception of the visual world to read.

The Perception of the Visual World. By James J. Gibson. U.S.A.: Houghton Mifflin Company, 1950 (George Allen & Unwin, Ltd., London). Price 35s.

A scheme is developed for classifying the types of motion perceived by a humanlike robot. It is assumed that the robot receives visual images of the scene using a perspective system model. Equations, theorems, concepts, clues, etc., relating the objects, their positions, and their motion to their images on the focal plane are presented. >

We report a unique concept to implement a high-order mode pass filter using mode converters. Our proposed design method implements a high-order mode pass filter of any order, uses different mode converters available, and applies to a variety of planar lightwave circuit material platforms. We fabricate a broadband fundamental mode filter device using a Mach–Zehnder interferometer and Y-junctions to demonstrate our idea. The performance of the fabricated device is demonstrated experimentally in the wavelength range of 1.530–1.565 μm (C-band). This filter exhibits a simulated extinction ratio of 37 dB with an excess loss of 0.52 dB for the first-order mode transmission.

In a network topology, it is very usual to use various kinds of routing protocol for forwarding packets. A routing table is used in the memory of a router that keeps the track of routes to particular network destination and the most popular routing algorithms used to forward packets are Routing Information Protocol (RIPv2), Enhanced Interior Gateway Routing Protocol (EIGRP) and Open Shortest Path First (OSPF). The ultimate concentration of this research work is to depict the performance analysis comparison of these three dynamic routing protocols and redistribution among the protocols. Eight Cisco routers and a switch are used in our simulated network topology where four routers with different protocols directly connected with the switch take the responsibility for the redistribution algorithm.

The intention of designing a robot is to facilitate the human beings through giving security and working as a helping hand through reprieving. The technology used in this rescue and security robot has a number of important features such as robotic car control by cell phone, automatically avoiding obstacles in its way. It can sense gas, smoke and provide an alert through text messaging. The robot can detect bombs, pick and place objects and also do distance measurements. A high quality wireless video camera equipped with a stepper motor for the omni-directional view is used for the spying purpose which is mounted on the robo car to send real video images and audio signals. These audio and video stream received by the receiver unit can be used to take proper steps according to the received signals. This robot can also be used to reach places where humans cannot reach like hidden places, small tunnels. The ultimate focus of this system is to offer far possible security for the human being. In this paper, we have illustrated our work by using the entire sub modules.

Electro-optic Mach-Zehnder interferometer (MZI) switches are well known devices in optical systems for their high speed of operation. In next generation optical network, such switches have wide applications due to their high switching capability and great reliability. In this paper we have investigated the enhanced performance of an electro-optic switch made by titanium diffused lithium niobate (Ti:LiNbO3) functioned as waveguide medium based on integrated Mach-Zehnder interferometer (MZI) at 1.55 μm wavelength. The performance of the switch is optimized for low switching voltage, low insertion loss, high extinction ratio. This is done by varying the strip thickness of titanium, interferometer arm length, arm gap, waveguide width, gap in the coupling region of the 3 dB couplers, and center position of second electrode deposited on integrated Mach-zehnder Interferometer arm with respect to the original axis of the switch. The designed switch gives lowest insertion loss of 0.00881dB and highest extinction ratio of 33.581 dB at 8.8 V.

This paper represents the feasibility study of a grid connected PV system with battery backup in south-east part of Bangladesh. In Bangladesh, only 53% of the total population gets access to grid power and yet, the current consumers cannot be provided with uninterrupted and quality supply of electricity due to the inadequate generation compared to the national demand. The world is gradually moving towards sustainable renewable energy sources due to diminishing fossil fuel energy resources and increasing demand for power. Most of the power stations in Bangladesh are based on fossil fuels. Fossil fuels are not environment friendly and are responsible for global warming. So a renewable grid connected power system with battery backup can be a better option to provide continuous power in a load shedding prone country like Bangladesh and also to reduce the emission of greenhouse gases. Our proposed system is simulated using HOMER optimization tool and the simulation results and analysis of the system are presented in the paper
