Introduction

Ex: An ultrasonic signal at 200kHz and another one at 201kHz will generate a 1kHz tone and a 401kHz signal which is inaudible to the human ear.

If an AM signal with a non-zero carrier amplitude is passed through Air, it is self-demodulated

ATM User Interface Design
Requirements
A statement of requirements for a portion of the system may be extracted from the use cases and other Inception documents. A brief narrative is useful for identifying the problem domain objects (concepts).
A bank customer is able to access his or her account using an automatic teller machine. To be able to use an ATM a customer must first register an account number and a passcode number. The customer’s information is then added to a list of registered users. The ATM use ....etc

To fulfill the requirements of traffic on Indian railways it has become necessary to run the vehicle with high speed and heavier loads. With the increase in speed and load of trains the tractive and braking forces on rails will also increase. Consequently, it has become important to investigate the safety of sub-structures of existing bridges. Hence the share of force resisted by individual sub-structural elements should be estimated more accurately than given by the present specifications which are based on a few field trials, and are not real ....etc

Human-computer interaction (HCI) is the study of how people design, implement, and use interactive computer systems and how computers affect individuals, organizations, and society. This encompasses not only ease of use but also new interaction techniques for supporting user tasks, providing better access to information, and creating more powerful forms of communication. It involves input and output devices and the interaction techniques that use them; how information is presented and requested; how the com ....etc

Human“computer interaction (HCI) is the study of interaction between people (users) and computers. It is often regarded as the intersection of computer science, behavioral sciences, design and several other fields of study. Interaction between users and computers occurs at the user interface (or simply interface), which includes both software and hardware, for example, general-purpose computer peripherals and large-scale mechanical systems, such as aircraft and power plants. The Association for Computing Machinery defines human-computer i ....etc

Abstract:
In this seminar the analysis of soil-structure interaction effects and of multiple support excitation on the seismic response of long-span cable-supported bridges are presented. The purpose of this seminar is to provide a better understanding of the dynamic performance of cable supported bridges under earthquake excitation, considering the spatial variability of the ground motion and the complex phenomena of soil-bridge interaction, so that such effects can be included in the design and rehabilitation process. Amplification of struct ....etc
