presently there are a number of fine and sensitive methods for determining chemical or biochemical substance among which bio electrodes represent the most recent development. bioelectrodes consist of biologically active materials (e.g enzyme, antibody, whole cell or cell fragments) held in close proximity to a suitable electrochemical transducer that sense specific electroactive enzyme substrat...

Abstruct-In order to use a wrist-mounted sensor (such as a camera) for a robot task, the position and orientation of the sensor with respect to the robot wrist frame must be known. We can find the sensor mounting position by moving the robot and observing the resulting motion of the sensor. This yields a homogeneous transform equation of the form A X = XB, where A is the change in the robot wri...

Experimental evidence is presented that mitochondrial oxidative phosphorylation is dependent on oxygen concentration in its physiologic range both in vivo and in vitro. Mitochondrial oxidative phosphorylation is considered to act as a tissue oxygen sensor important for controlling local vascular resistance.

A simple simulation using SIMULINK is presented to model the thermal/control behaviour of a domestic gas boiler. The simulation was the first step in a research programme to investigate the efficacy of control using an oxygen sensor. A brief review of boiler control is used to outline current practice and research developments. Ratio control in several forms has been investigated. Performance i...

in recent years, demand for biological sensors which are capable of fast and accurate detection of minor amounts of pathogens inreal‑time form has been intensified. acoustic wave (aw) devices whose performance is determined by mass sensitivity parametersand quality factor are used in biological sensors as platforms with high quality. yet, current aw devices are facing many challengessuch as the...

in recent years many researches are carried out to develop robots for agricultural applications. one of the main steps in agricultural robot fabrication is the generation of guidance signals. the objective of this research was a feasibility study of ultrasonic sensors in generating guidance signals to determine the position and orientation of a mobile robot for greenhouse applications. a series...

The research areas of mobile robotic sensors lie in the intersection of two major fields of investigations carried out by quite distinct communities of researchers: autonomous robots and mobile sensor networks. Robotic sensors are micro-robots capable of locomotion and sensing. Like the sensors in wireless sensor networks, they are myopic: their sensing range is limited. Unlike the sensors in w...
