An innovative method for determining the junction temperature TJ as a function of the cell voltage V of a photovoltaic (PV) cell for varying operating power levels at pre-determined values of irradiation levels is presented. Since the junction of a PV cell that is in operation is inaccessible for obtaining a measure of TJ, a novel indirect temperature measurement method suitable for determining the TJ is proposed in this paper. The electronically controllable load required to establish different operating power levels for obtaining the TJ - V characteristic of a photovoltaic (PV) cell is implemented with a MOSFET, suitably controlled to act as a variable load resistor. Microcontroller based hardware with associated software were developed to automate the entire measurement process. Results obtained from a prototype TJ - V measurement unit built and tested establish the efficacy of the proposed method.

In this paper we propose the use of a monitoring system to enhance the degree of efficiency of photovoltaics. We discuss electric vehicles (EVs) as well as hybrid electric vehicles (HEVs) as potential target applications. For these kinds of vehicles we evaluate different connection opportunities for photovoltaics within an on-board power supply. Furthermore, we present a novel connection opportunity to avoid disadvantages from other approaches. We illustrate how our monitoring system responds to changing solar radiation conditions thereby selecting suitable maximum power point tracking (MPPT) strategies. Additionally, we increase the degree of efficiency by disconnecting shadowed photovoltaic (PV) cells from unshadowed PV cells. Moreover, predictions on the energy output of the PV installation are provided as helpful information to the driver.

In radiation environments ultrasonic nondestructive evaluation has great potential for improving reactor safety and furthering the understanding of radiation effects and materials. In both nuclear power plants and materials test reactors, elevated temperatures and high levels of radiation present challenges to ultrasonic NDE methodologies. The challenges are primarily due to the degradation of the ultrasonic sensors utilized. We present results from the operation of an ultrasonic piezoelectric transducer, composed of bulk single crystal AlN, in a nuclear reactor core for over 120 MWHrs. The transducer was coupled to an aluminum cylinder and operated in pulse echo mode throughout the irradiation. In addition to the pulse echo testing impedance data was obtained. Further, the piezoelectric coefficient d33 was measured prior to irradiation and found to be 5.5 pC/N which is unchanged from as-grown samples, and in fact higher than the measured d33 for many as-grown samples.

The purpose of this study is to assess the effect of different noise reduction filters on ultrasound images. In particular two denoising filters based on thresholding and wavelet coefficients are proposed. Simulation results show that the techniques developed increase the image quality and then allow a more accurate diagnosis.

This paper reports the design and development of a smart wireless sensor network (WSN) for an agricultural environment. Monitoring agricultural environments for various factors such as temperature and humidity along with other factors can be of significance. The ability to document and detail changes in parameters of interest has become increasingly valuable. Investigations were performed for a remote monitoring system using WiFi, where the wireless sensor nodes are based on WSN802G modules. These nodes send data wirelessly to a central server, which collects the data, stores it and allows it to be analyzed and displayed as needed.

In Atomic Force Microscopy the force between the tip and the sample is controlled in a feedback loop in order to prevent damage to the tip and the sample during scanning, and also to convert the force measurement into an estimate of the sample topography. In this paper it is experimentally shown that within the design of the control system a direct trade-off has to be made between the bandwidth of the feedback loop and the accuracy of the topography estimation due to the dynamical uncertainty of the systems. Several method are suggested to reduce the dynamical uncertainty of the imaging system to allow both faster and more accurate AFM imaging. Moreover, a method is discussed and experimentally validated to compensate for the loss in imaging accuracy due to the hysteresis within the piezoelectric actuators.

In this work, a wind speed measurement model based on Evidence Theory and Data Fusion of the time-of-flight (ToF) information is presented. The fusion is obtained through threshold detection (TH) and phase difference (PD) techniques For this purpose, the evidence theory using fuzzy set theory and interval analysis has been successfully used to represent (from random-fuzzy variables - RFV) and assessment the uncertainty ToF measurement. A data fusion method is presented based on the concept of relations of compatibility and OWA operators with partial aggregation to the variables being fused. Simulation results are presented to several measured values using the TH and PD techniques.

Based on the combination of non-dispersive infrared (NDIR) transmission and photoacoustic absorption spectroscopy (PAS) measurements, the detection of multiple gases and their mixtures was investigated using an integrated, microstructured Fabry-Pérot Filter (FPF). The proposed versatile system can be utilized as IR spectrometer for a wide range of gas concentrations using IR transmission spectroscopy (IRTS) measurements for high concentrations and PAS for low concentrations. The system is based on low cost components: a thermopile detector for the IRTS signal, condenser microphones for the PAS signal and a microstructured IR source. The source is modulated electrically with a frequency in the range of 1 to 10 Hz, i.e. using a nonresonant operating mode of the gas chamber. The investigated, commercially available FPF allows the analysis of gases with gas specific absorption bands between 3.9 and 5.0 μm. Our IRTS system, therefore, can be adapted for many application scenarios in which two or more gases have to be detected over a wide concentration range. One example is the isotope specific detection of carbon dioxide (CO2) for the urea breath test.

Measurement of Internet Protocol Packet Delay Variation (IPDV) is a relevant issue in application involving real time video streaming. Generally, this quantity is compared with predefined thresholds (whose value depends upon the application requirements) to verify the quality of service to the end user. However, the exceeding of this threshold only for short time intervals and with relatively low repetition rates, generally does not imply a significant decrease of the user perceived quality. Vice-versa, IPDV values not exceeding the admitted threshold but very close to this value for long time intervals and characterized by relatively high repetition rates can significantly affect the user perceived quality. Consequently, a study of the correlation among the measured IPDV values and some performance metrics directly related to the quality perceived by the user has to be accurately investigated. On the other hand, literature concerning with IPDV evaluation does not provide some important information about the measurement procedure, such as measurement rate, how to collect the obtained result in a single estimator, the time interval on which the estimator is evaluated, and so on. Consequently, the absence of these important aspects about the measurement procedure makes very critical the comparison between the evaluated IPDV and the above-mentioned thresholds, thus making even more ambiguous the evaluation of the quality of service to the end user. In this framework, the aim of the paper is to design and fine tune an IPDV estimator able to reliably estimate and detect the objective service degradation from the user perspective.

This paper presents delay dependent teleoperation strategy over wide-area communication network under symmetric and asymmetric time varying transmission delay. The local and remote device is coupled by delayed position and adaptive impedance reflection of the remote slave-environment's interaction force. Local nonlinear adaptive terms for both master-slaves are deployed to estimate uncertain parameter of the gravity loading vector. An adaptive impedance force-reflection algorithm is designed for slave device to estimate the remote impedance characteristics of the interaction force between slave and remote task environment. The on-line estimated remote slave-environment's characteristics are then transmitted back to the master device via using communication channels in order to reproduce remote slave-environment's interaction force at the human operator hand. Lyapunov-Krasovskii-like functional is employed to derive stability condition for the coupled master-slave teleoperators. Finally, simulation is conducted to demonstrate the validity of the proposed design for real-time applications.
