The best optical microscopes can see structures in the 200 – 400 nm range, at their limits of resolution.
The STM can “see” structures on the order of 0.1 nm —another SPM, the AFM—can distinguish things on the order of 100 nm .
Optical microscopes are “diffraction limited”—the wavelength range of visible light (400-750 nm) sets the size of the smallest thing that can be imaged: ~ 400 nm.
Scanning Probe Microscopes don’t use visible light—they depend on measuring intermolecular ....etc

FINGER PRINT BASED ACCESS CONTROL SYSTEM
ABSTRACT:
According ancient Greek scripts BIOMETRICS means study of life. Biometrics studies commonly include fingerprint, face, iris, voice, signature, and hand geometry recognition and verification. Many other modalities are in various stages of development and assessment. Among these available biometric traits Finger Print proves to be one of the best traits providing good mismatch ratio and also reliable. The present scenario to operate a bank locker is with locks which are hav ....etc

Biometrics uses a persons biological characters to identify him such as fingerprint scanning, retinal scanning , DNA fingerprinting etc.Biometrics equipped Automatic Teller Machines (ATMs) to provide a number of social services including identity verification and disbursement of social security, unemployment, welfare and pension benefits to a la rge segment of the population.
Biometric Access Control System
The goal of this project is to design and assemble a biometric access control system that uses fingerprint scanning and recognition to au ....etc

a networked control-system laboratory for the remote control of processes is presented. The laboratory allows the students to develop network-based control systems with the use of an architecture consisting of I/O devices, communication modules, and server-client applications implemented with supervisory control and data acquisition environment facilities, and to operate on real pilot plants through an intranet and the Internet. Three examples were presented, demonstrating the potentiality of the laboratory to remotely control the processes and ....etc
