The article looks at the corrosion issues surrounding the U.S. power and paper industries. The prevention of corrosion is not a one-size fits all solution. In fact, there are strategies and techniques for varying corrosion conundrums and costs billions of dollars a year. Corrosion occurs more rapidly as impurities concentrate in under-deposit corrosion. Corrosion and deposition in water chemistry is difficult to control. The power industry is responding to the problem by monitoring dissolved oxygen. Companies use sensors sensitive to parts per billion levels of oxygen to help control the pH.

We envision a new generation of computation devices, computational materials, which are self-sustainable, cheaply manufactured at scale and exhibit form factors that are easily incorporated into everyday environments. These materials can enable ordinary objects such as walls, carpet, furniture, jewelry, and cups to do computational things without looking like today's computational devices. Self-powered Audio Triboelectric Ultra-thin Rollable Nanogenerator (SATURN) is an early example of a computational material that can sense vibration, such as sound. SATURN can be manufactured from inexpensive components, is flexible so that it can be integrated into many different surfaces, and powers itself through the sound or vibration it is sensing. Using radio backscatter, we demonstrate that SATURN's sensed data is passively transmitted to remote computers, alleviating the need for batteries or any wired power for the material itself. The proliferation of these types of computational materials ushers an era of Internet of Materials, further blurring the distinction between the physical and digital worlds. [ABSTRACT FROM AUTHOR]

Approximate multipliers are used in error-tolerant applications, sacrificing the accuracy of results to minimize power or delay. In this paper we investigate approximate multipliers using static segmentation. In these circuits a set of $m$ contiguous bits (a segment of $m$ bits) is extracted from each of the two $n$ -bits operand, the two segments are in input to a small $m\times m$ internal multiplier whose output is suitably shifted to obtain the result. We investigate both signed and unsigned multipliers, and for the latter we propose a new segmentation approach. We also present simple and effective correction techniques that can significantly reduce the approximation error with reduced hardware costs. We perform a detailed comparison with previously proposed approximate multipliers, considering a hardware implementation in 28 nm technology. The comparison shows that static segmented multipliers with the proposed correction technique have the desirable characteristic of being on (or close to) the Pareto-optimal frontier for both power vs normalized mean error distance and power vs mean relative error distance trade-off plots. These multipliers, therefore, are promising candidates for applications where their error performance is acceptable. This is confirmed by the results obtained for image processing and image classification applications. [ABSTRACT FROM AUTHOR]

Information exchanges among interacting agents play a significant role in guaranteeing successful completion of the desired coordinated control tasks for a multi-agent system (MAS). Furthermore, these information exchanges are often performed over some open and resource-constrained communication networks, thereby making security and resource efficiency vitally important for various multi-agent coordinated control problems. This paper addresses a secure dynamic event-trigger-based resilient consensus control problem for an MAS in the presence of both sensor and actuator attacks. First, a distributed adaptive compensator is introduced for prediction of unavailable system states. Due to the existence of sensor and actuator attack signals, a secure dynamic event-triggered mechanism is then proposed, and a resilient control strategy is further devised for the paralyzed MAS. It is theoretically proved that the controlled MAS is asymptotically stable and asymptotic consensus is eventually achieved among the coordinated agents regardless of the attacks and constrained resources. Finally, three examples are provided to illustrate the effectiveness of the proposed strategy. [ABSTRACT FROM AUTHOR]

This paper considers the quadratic control problem of discrete-time Markov jump linear systems with constraints on the norm of the state and control variables. We assume that the Markov chain parameter is not available, and instead, there is a detector, which emits signals providing information on this parameter. It is desired to derive a feedback linear control using the information provided by this detector in order to stochastically stabilize the closed-loop system, satisfy the constraints whenever the initial conditions belong to an invariant set, and minimize an upper bound for the quadratic cost. We show that a linear matrix inequality (LMI) optimization problem can be formulated in order to obtain a solution for this problem. Two other related problems, one for minimizing the guaranteed quadratic cost considering fixed initial conditions and the other for maximizing an estimate of the domain of an invariant set, can also be formulated using our LMI approach. This paper is concluded with some numerical simulations. [ABSTRACT FROM AUTHOR]

For massive multiple-input multiple-output (MIMO) systems, linear minimum mean-square error (MMSE) detection has been shown to achieve near-optimal performance but suffers from excessively high complexity due to the large-scale matrix inversion. Being matrix inversion free, detection algorithms based on the Gauss–Seidel (GS) method have been proved more efficient than conventional Neumann series expansion-based ones. In this paper, an efficient GS-based soft-output data detector for massive MIMO and a corresponding VLSI architecture are proposed. To accelerate the convergence of the GS method, a new initial solution is proposed. Several optimizations on the VLSI architecture level are proposed to further reduce the processing latency and area. Our reference implementation results on a Xilinx Virtex-7 XC7VX690T FPGA for a 128 base-station antenna and eight user massive MIMO system show that our GS-based data detector achieves a throughput of 732 Mb/s with close-to-MMSE error-rate performance. Our implementation results demonstrate that the proposed solution has advantages over the existing designs in terms of complexity and efficiency, especially under challenging propagation conditions.

Sparse code multiple access (SCMA) is a promising multiple access technology candidate for the next-generation communication system, which can dramatically improve spectral efficiency. However, the major challenge of SCMA is the very high detection complexity. Stochastic computing is a new number representation, which can carry out complex computations with very simple logics. In this paper, we extend the application of stochastic computing to SCMA detection and propose a low complexity stochastic SCMA detector. We also design three novel stochastic logic architectures: a new low hardware cost bit stream generation architecture, a low hardware cost stochastic function node update architecture and a fast converging stochastic variable node update architecture. Analysis and simulation results show that the proposed stochastic SCMA detector saves 69% complexity compared with the traditional SCMA detectors with a comparable bit error rate performance. The synthesis results with SIMC 65-nm CMOS technology show that the proposed stochastic SCMA detector achieves 640 Mbps total system throughput with only 1.45-mm $^{{{2}}}$ cell area.

This paper presents a linear current-reuse sampling phase detector for a single-loop type-I phase-locked loop (PLL) to simultaneously achieve a wide loop bandwidth and low control voltage ripple, resulting in low RMS jitter and reference spur, while minimizing the chip area by avoiding an explicit loop filter. Fabricated in 28-nm CMOS, the PLL prototype measures an integrated jitter of 440 fsRMS, and a spur level of −63.9 dBc at 3.296 GHz. It draws 3.3 mW at a 0.9-V supply and scores a jitter-power figure-of-merit (FoM) of −241.9 dB. With a 103-MHz reference input, a bandwidth of ~20 MHz aids suppressing significantly the ring VCO’s phase noise (PN), leading to an in-band PN of −116 dBc/Hz at 1-MHz offset. The die size is 0.003 mm2. [ABSTRACT FROM AUTHOR]

Researchers at MIT have developed a new technology that could make diagnosing lung cancer easier and more accessible. The technology involves inhaling nanoparticle sensors, which, if they encounter cancer-linked proteins in the lungs, produce a signal that can be detected in urine using a simple paper test strip. This approach could potentially replace or supplement the current gold standard for diagnosing lung cancer, low-dose computed tomography (CT), and could have a significant impact in low- and middle-income countries where CT scanners are not widely available. The researchers plan to conduct further studies to determine the effectiveness of the technology in detecting human cancers. [Extracted from the article]

Soft-input soft-output (SISO) detector for the iterative detection and decoding of coded spatial modulation (SM) signals needs to compute the extrinsic bit log-likelihood ratio (LLR) associated with each detected bit. The maximum logarithmic maximum a posteriori (max-log-MAP) detector is known to perform closely to the optimal logarithmic maximum a posteriori (log-MAP) detector with much lower computational complexity. In this paper, we first apply several mathematical tricks to derive a new and low-complexity algorithm for the max-log-MAP detector. The proposed algorithm features a new tree pruning technique to visit few lattice points and a smart list administration technique to retain a max-log-MAP detector. By following the proposed algorithm, we then design a hardware architecture for SISO detection of coded SM signals over the scenario of 64-QAM symbols, 8 transmit antennas, and 4 receive antennas. Under the TSMC 40 nm CMOS technology, the VLSI implementation results reveal that our architecture requires 46.4K gates and leads to detection throughput 450 Mbps, while operating at clock frequency 400 MHz and consuming power 46 mW. Being the first hardware architecture for SISO detection of coded SM signals, our proposed low-cost max-log-MAP detector is very attractive. [ABSTRACT FROM AUTHOR]

This paper presents a compact impulse-radio ultra-wide band non-coherent receiver architecture for high data rate wireless neural recordings from active high-density CMOS-probes. The system is capable of receiving, synchronizing, and demodulating a continuous on–off keying pulse stream at 1 Gb/s and 4 GHz center frequency using an active area of 0.34 mm2 and a single 31.25 MHz crystal reference. An asynchronous threshold energy detector, including a pulse enhancement baseband with an all-digital back-end, recovers incoming transmitter clock (CDR) and acquires packet synchronization based on a data-aided mechanism (DPR). Results shows that a prototype of the receiver integrated in a 130 nm CMOS process recovers synchronization in 30 ns. The system includes I/O output buffers and driver logic at 1.8 V supply operating at 1 GHz on a 50 $\Omega $ load and crystal oscillator. Overall, it consumes 115 pJ/pulse, while the receiver core only consumes 12 pJ/pulse. This paper presents the receiver architecture, and experimental results show a sensitivity of −38 dBm at 10−3 packet error ratio. [ABSTRACT FROM AUTHOR]

We design and complete an experiment of debris detection under the Milky Way background. The data analysis shows that the strong Milky Way background reduces the detector's ability to detect the weak debris, but has little effect on the accuracy of the astronomical positioning of debris. This paper verifies the rationality of using the limit detection magnitude method based on the detection probability to characterize the limit detection ability of detectors. It also verifies the feasibility of using the simulation method to increase the data completeness. The work in this paper will provide a basis for the design of the spacebased detectors and the development of the detection experiments. [ABSTRACT FROM AUTHOR]

This paper introduces an event-based luminance-free algorithm for line and segment detection from the output of asynchronous event-based neuromorphic retinas. These recent biomimetic vision sensors are composed of autonomous pixels, each of them asynchronously generating visual events that encode relative changes in pixels’ illumination at high temporal resolutions. This frame-free approach results in an increased energy efficiency and in real-time operation, making these sensors especially suitable for applications such as autonomous robotics. The proposed algorithm is based on an iterative event-based weighted least squares fitting, and it is consequently well suited to the high temporal resolution and asynchronous acquisition of neuromorphic cameras: parameters of a current line are updated for each event attributed (i.e., spatio-temporally close) to it, while implicitly forgetting the contribution of older events according to a speed-tuned exponentially decaying function. A detection occurs if a measure of activity, i.e., implicit measure of the number of contributing events and using the same decay function, exceeds a given threshold. The speed-tuned decreasing function is based on a measure of the apparent motion, i.e., the optical flow computed around each event. This latter ensures that the algorithm behaves independently of the edges’ dynamics. Line segments are then extracted from the lines, allowing for the tracking of the corresponding endpoints. We provide experiments showing the accuracy of our algorithm and study the influence of the apparent velocity and relative orientation of the observed edges. Finally, evaluations of its computational efficiency show that this algorithm can be envisioned for high-speed applications, such as vision-based robotic navigation. [ABSTRACT FROM AUTHOR]

Such a transformer enables the five-moduli set to utilize components that are (or will be) designed for the three-moduli set such as sign detectors. [ABSTRACT FROM AUTHOR]
