ABSTRACT

Here I would like to present the Pico-1 Electronic Nose (EN) based on thin film semiconductor sensors and an application to the analysis of two groups of seven coffees each. Cups of coffee were also analyzed by two panels of trained judges who assessed quantitative descriptors and a global index (called Hedonic Index, HI) characterizing the sensorial appeal of the coffee. Two tasks are performed by Pico-1. First, for each group, we Analysis performed the classification of the se ....etc

Lightning and Surge Protection Of Modern Electronic Systems

Introduction
In virtually all aspects of our modern lives, microprocessors and integrated circuits (ICs) are hard
at work processing digital data, controlling critical systems and communicating information
through ever-expanding global networks. These now common components have dramatically
lowered system costs while increasing the power and flexibility of modern electronic systems in a
manner unimaginable just a few years ago. Yet, few developers se ....etc

ELECTRONIC Noses (EN), in the broadest meaning, are instruments that analyze gaseous mixtures for discriminating between different (but similar) mixtures and, in the case of simple mixtures, quantify the concentration of the constituents. ENs consists of a sampling system (for a reproducible collection of the mixture), an array of chemical sensors, Electronic circuitry and data analysis software. Chemical sensors, which are the heart of the system, can be divided into three categories according to the type of sensitive material used: inorganic ....etc

India is worldâ„¢s largest democracy. It is perceived to be charismatic one as it accommodates cultural, regional, economical, social disparities and still is able to stand on its own. Fundamental right to vote or simply voting in elections forms the basis of Indian democracy.
In India all earlier elections be it state elections or centre elections a voter used to cast his/her vote to his/her favorite candidate by putting the stamp against his/her name and then foldi ....etc

ABSTRACT
In an ever-developing world, where electronic devices are duplicating every other sense of perception, the sense of smell is lagging behind. Yet, recently, there has been an urgent increase in the need for detecting odours, to replace the human job of sensing and quantification. Some of the most important applications fall in the category where human beings cannot afford to risk smelling the substance. Other important applications are continuous monitoring, medical applications, etc. These application ....etc

The circuit presented here can be-used as a lock for important elec¬tronic/electrical appliances. When card is inserted inside its mechanism, depending upon the position of punched hole on the card, a particular appliance would be switched on. The card is inserted just like a floppy disk inside the disk drive. This card should be rectangular in shape with only one punched hole on it. T7 o The circuit uses eight photo-transistors (T1 through T8). When there is no card in the lock, light from incan¬descent lamp L1 (40-watt, 230V) ....etc

ELECTRONIC NOSE
ABSTRACT
The perception of volatile compounds by the human nose is of great importance in evaluating the quality of foods. Therefore, it is not surprising that repeated efforts have been made over the years to introduce instruments operating on a similar principle as the human nose: the electronic nose is an instrument that encloses the human sensitivity to the objectivity of the instrumental response and supplies results similar to the human nose and in short time.
An electronic nose is an instrument wh ....etc

The electronics field is developing at a fast rate. Each day the industry is coming with new technology and products. The electronic components play a major role in all fields of life. The scientists had started to mimic the biological world. The development of artificial neural network (ANN), in which the nervous system is electronically implemented is one among them.

The scientists realized the importance of the detection and identification of odor in many fields. In human body it is achieved with the help of one of the sense organ, the n ....etc

The remarkable properties of carbon nanotubes may allow them to play a crucial role in the relentless drive towards miniaturization at the nanometre scale.

Nanotechnology is predicted to spark a series of industrial revolutions in the next two decades that will transform our lives to a far greater extent than silicon microelectronics did in the 20th century. Carbon nanotubes could play a pivotal role in this upcoming revolution if their remarkable electrical and mechanical properties can be exploited.

Since the first measurements were ma ....etc
