In the paper is proposed a procedure to characterize the distortion of the exponential signal generated by Arbitrary Wave Generator (AWG). The basis of the procedure is the same in the case the AWG is set to generate sinusoidal signal. In particular, the resulting signal from the difference between the exponential generated signal and the sinusoidal reference one is digitalized by low resolution and...
In the paper the problem of the reuse of cubilot slag for the production of bricks usable as building materials is studied. The results of the experimental tests demonstrate that the typical measurement techniques defined in the UNI-EN guidelines to evaluate the properties, the characteristics and the possible use of the traditional ceramics, can be applied to these waste bricks. However, these measurement...
This paper reports about a research project aimed to the development of an agent-based software architecture for a Distributed Measurement System (DMS) as a Cyber Physical Systems (CPS) part. Agents are used because they naturally support the modeling of the interaction between the measurement nodes and provide the concept of action, useful to implement measurement procedures. A support to model continuity...
In the mineral part of the teeth the calcium phosphates and calcium carbonates are combined in a collagen with the mucopolysaccharides of the organic matrix. The infection on the tooth surface caused by bacteria can modify the tooth structures resulting in the tooth decay. In order to determine the modification on the tooth structure the use of thermal analysis technique is proposed. With this aim...
The recent literature proposes the smartphone's camera to evaluate the arterial blood oxygenation (SpO2%) with the characteristic of friendly and ubiquitous measurement instrument. Some issues remain open, making difficult the compensation of artefacts causing error in the estimation of the photoplethysmogram signal (PPG) and not guarantying that the measurement of SpO2% is correctly executed. In...
The paper deals with a low cost measurement station for DAC dynamic characterization. The characterization method is based on the estimate of the DAC output voltage through the measurement of time intervals. These are performed by the DSP, which evaluates the time between two edges of the input signal. A proper system has been implemented with the aim of conditioning the DAC output signal in order...
The paper deals with the experimental implementation of a test method to perform the dynamic characterization of the Digital to Analog Converter (DAC). This test method is based on the experimental detection of the Zero Crossing Time Sequence (ZCTS) into the resulting signal difference between the DAC output and the auxiliary reference one. From the ZCTS the numerical procedure reconstructs in the...
The innovative software architecture of the wireless distributed measurement system (W-DMS) including the Web-enabled measurement application repository server (MARS) is proposed. The duties of the MARS are devoted to permit the connectivity by the various wireless communication protocols, such as GPRS/UMTS, WiFi and Bluetooth, and to supply the mobile devices, as personal digital assistant and smartphone,...
