Driving under the influence (DUI) is a synonymous term that represents the criminal offense of operating a motor vehicle while being under the influence of alcohol. Semiconductor oxides such as SnO2, TiO2, and ZnO have been more successfully employed as sensing materials compare to organic semiconductors for the detection of ethanol gas concentration. This work investigates the fabrication and ...

The 600 A and 120 A circuits of the inner triplet magnets of the Large Hadron Collider are powered by resistive gas cooled current leads. The current solution for controlling the gas flow of these leads has shown severe operability limitations. In order to allow a more precise and more reliable control of the cooling gas flow, new flowmeters will be installed during the first long shutdown of t...

In this paper detailed curves showing the behaviour of resistive plate chambers efficiency and time resolution as a function of temperature and operating voltage are presented. The results show that the operating voltage scales well according to the rule: operating voltage/gas density = constant.

Selectivity and low power consumption are major challenges in the development of sophisticated gas sensor devices. A sensor system is presented that unifies selective sensor-gas interactions and energy-harvesting properties, using defined organic-inorganic hybrid materials. Simulations of chemical-binding interactions and the consequent electronic surface modulation give more insight into the c...

Methods for estimating a car's length are presented in this paper, as well as the results achieved by using a self-designed system equipped with two anisotropic magneto-resistive (AMR) sensors, which were placed on a road lane. The purpose of the research was to compare the lengths of mid-size cars, i.e., family cars (hatchbacks), saloons (sedans), station wagons and SUVs. Four methods were use...

In this paper is proposed a dynamic torque, rotational speed, and shaft position sensor. It built of magnetic elastomer coating directly applied over rotating shaft. The sensor used for precise measurements changes in torque it usable at high speeds, on the device based material deformation corresponding change field amplitude direction. design simple can acquire reliable readings wide range sp...
