Abstract

Construction and characterization of a simple but flexible, low cost diode laser system for the excitation of carbon quantum dots as a treatment method for ocular cancers is reported. System was designed to deliver maximal amount of laser diode radiant flux to the eye of the test mice using optical cable. Detailed electronic circuit layouts of the laser diode voltage controller, supplying maximum 3 V of voltage with 20 mV resolutions, and functional description of all other components (optical cable delivery system and supporting console) are given. The system features visual signalization when the laser diode module is powered. Since the laser diode radiant flux is directly dependent on the input voltage, measurement was performed in order to obtain approximation function of this dependency. Purpose of this function is to eliminate radiant flux measurement before each experiment which requires controlled conditions.

14. Signal acquisition and processing in the magnetic defectoscopy of steel wire ropes.

Author

Radovanovic, Ilija D., Rajovic, Nikola M., Rajovic, Vladimir M., and Jovicic, Nenad S.

Abstract

In this paper, the system that resolves the problem of wire rope defects using magnetic method of inspection is presented. Implementation of the system should provide for full monitoring of wire rope condition, according to the prescribed international standards. The purpose of this system, except to identify defects in the rope, is to determine to what extent the damage has been done. The measurement procedure provides for a better understanding of the defects that occur, as well as the rejection criteria of used ropes, that way increasing their security. Hardware and software design of appliance for recording defects and test results are presented in this paper. [ABSTRACT FROM PUBLISHER]

Abstract

In addition to the accelerated development of standard and novel types of rechargeable batteries, for electricity storage purposes, more and more attention has recently been paid to supercapacitors as a qualitatively new type of capacitor. A large number of teams and laboratories around the world are working on the development of supercapacitors, while their ever-improving performances enable wider use. The major challenges are to improve the parameters of supercapacitors, primarily energy density and operating voltage, as well as the miniaturization, optimization, energy efficiency, economy, and environmental acceptance. This chapter provides an overview of new techniques and technologies of supercapacitors that are changing the present and future of electricity storage, with special emphasis on self-powering sensor and transmitter systems. The latest achievements in the production, modeling, and characterization of supercapacitor elements (electrode materials, electrolytes, and supporting elements) whose parameters are optimized for long-term self-supply of low power consumers (low voltage, high energy density, and low leakage current, etc.) are considered.
