However, many users do not possess sufficient expertise in modern digital design techniques to achieve the greatest benefit from FPGA technology and limitations in current commercial tools do not support the simulation of arbitrary models in FPGAs. Toward that end, we present the challenges to implementing Simulink models via high-level synthesis design techniques, the potential benefits of using this approach, and a preliminary tool that demonstrates one key step toward the automated simulation of arbitrary models. Such a tool would enable transparent, automated model translation from a graphical user interface to an FPGA for users without expertise in FPGA-based digital design.

The process uses a hybrid technique utilizing two commercially available tools, Simulink Coder and Xilinx Vivado HLD, as well as a middleware procedure to produce an accurate implementation of a model system in HDL, e.g. Verilog and VHDL. The implementation technique does not require expertise knowledge in Digital Design or Hardware Description Language HDL, yet it produces a complete description of the simulator in HDL. Using an example model of electric ship power system, we evaluate the effectiveness of the approach in developing a precise model in RTL for Real-Time simulation while accelerating the overall execution time.

There has been an ongoing effort to upgrade, improve and enhance the security and emergency response capability of the water infrastructure in order to maintain a reliable supply and delivery of drinking water in case of damage. In recent years, non-invasive monitoring of water pipelines has emerged as a promising technique due to cost and practical considerations. Challenges associated with monitoring such systems include quality of data sensing, timely and reliable communication, accurate data analysis and high power efficiency. To address these problems, we propose a distributed real-time detection algorithm for detecting rupture events in water pipelines non-invasively. The purpose is to suppress not only unnecessary transmission but also local processing in order to save power without sacrificing sensitivity or specificity of the events of interest. All these ...

Since excessive nitrate accumulation has negative impacts on the environment, the quantitative monitoring of nitrate levels in the field is a critical component of precision agriculture. Researchers recently showed the application of plasticized polyvinyl chloride electrodes in conjunction with electrochemical impedance spectroscopy (EIS) to monitor nitrate levels. In this paper, we show that nitrate doped polypyrrole (PPy(NO3−)) electrodes (which have a simpler fabrication) also have the potential of serving as nitrate sensors in EIS applications. To the knowledge of the authors, PPy(NO3−) electrodes have not been used before to monitor nitrate levels using EIS. Using a metric extracted from the low-frequency EIS behavior of our PPy(NO3−) electrodes, we also show the potential of realizing a nitrate sensor whose output response spans ∼100X for an input dosage range of 30ppm–6200ppm. This may lead to the future development of low-power and responsive nitrate sensors for large-scale field deployment.

Adopting the new outcomes required program coordinators to review and update their assessment plans in order to ensure efficient and effective assessment. The new implementations provided clarification for some of the outcomes that previously had been vague and difficult to measure. For example, outcome 3(d) “ability to function on multidisciplinary teams” was revised into its new 3(5) outcome “an ability to function effectively on a team whose members, together, provide leadership, create a collaborative and inclusive environment, establish goals, plan tasks, and meet objectives” [1]. While the new changes provided better clarification for many of the student outcomes, some of the newly added terms were introduced without a clear definition or explanation. For example, outcome 3 “ability to communicate effectively with a range...

The purpose is to suppress not only unnecessary transmission but also local processing in order to save power without sacrificing sensitivity or specificity of the events of interest. All these goals are accomplished by adaptive thresholding, a cascaded wake-up chain, local processing, and aggressive power management. Experimental results show that the proposed algorithm achieves high sensitivity and high specificity while reducing the total energy consumption significantly.

The platforms are deployed and monitored remotely on lifetime systems, such as underground water pipelines. Although similar systems have been proposed for monitoring seismic events and the structure health of bridges and buildings, several fundamental differences necessitate adaptation or redesign of the module. Specifically, rupture detection in water delivery networks must respond to higher frequency and wider bandwidth than those used in the monitoring of seismic events, structures, or bridges. The monitoring and detection algorithms can also impose a wide range of requirements on the fidelity of the acquired data and the flexibility of wireless communication technologies. We employ a non-invasive methodology based on MEMS accelerometers to identify the damage location and to estimate the extent of the damage. The key issues are low-noise power supply, noise floor of sensors, higher sampling rate, and the relationship among displacement, frequency, and acceleration. Based on the mentioned methodology, PipeTECT, a smart wireless sensor platform was developed. The platform was validated on a bench-scale uniaxial shake table, a small-scale water pipe network, and portions of several regional water supply networks. The laboratory evaluation and the results obtained from a preliminary field deployment show that such key factors in the implementation are crucial to ensure high fidelity of the acquired data. This is expected to be helpful in the understanding of lifeline infrastructure behavior under disastrous events.

It incorporates MEMS accelerometers for measuring vibration on the surface of a pipe to determine the change in water pressure caused by rupture and the damage location. This system enables various sensor boards and camera modules to be daisychained underground and to transmit data with a shared radio board for data uplink. Challenges include reliable long-range communication, precise time synchronization, effective bandwidth usage, and power management. The low-cost MEMS technology, saved wiring cost, and simple installation without destructive modification enable large-scale deployment at an affordable cost.
