In developed countries, companies active in the food retail sector consume about 20% of the total power required for cooling and are therefore ranked among them with the largest energy footprint after the industries. For this reason, refrigeration equipment manufacturers are increasingly focusing on methods that will reduce the power consumption required for its efficient operation. The solutions that are currently implemented mainly focus on interventions in the development phase of freezer units (better insulation, variable frequency compressors, etc.), which, however, do not adequately address the problem. This paper presents the development of an IoT-based technology device which, using machine learning techniques, aims to reduce the power consumption of refrigeration equipment and consecutively, the energy footprint of food retailers.

This work shows an ultra-miniaturised and ultralow-power CMOS current driver for biphasic intracortical microstimulation. The CMOS driver is composed of a leakage-based voltage-to-current converter and an H-bridge circuit providing biphasic charge-balanced current stimulation. The circuit has been simulated, fabricated and tested. The current driver consumes 1.87 µW with a supply voltage of 1.8 V, and it occupies a silicon area of 15×12.4 µm2. The driver works in linearity in the current range between 23−92 µA.

Over the last few years, computational power and intelligence are becoming more and more necessary in the sector of finance. More specifically, computational finance turns into a very popular topic for both academia and industry, where numerous published works from this field and especially investment and risk management, showcase the effects of these technological advancements. At the same time, the ever-increased computational demands have led to the deployment of various accelerators in order to meet both latency and power constraints for financial applications that vary from special purpose, made by economists, to general purpose Digital Signal Processing (DSP) applied in financial time-series. One of the most widely used applications, belonging to the 2nd category, is the Savitzky-Golay algorithm, a filter used for smoothing time-series data. In this work, we propose a mechanism that automatically creates different accelerated Savitzky-Golay filters for GPUs and FPGAs, based on a set of pre-accelerated templates. By evaluating the provided templates with a set of real use-case parameters, a speedup of x33.5 on the NVIDIA T4 GPU and x21.9 on the Alveo U50 FPGA is achieved compared with an Intel Xeon Gold 5218R CPU as a baseline, while achieving a decrease in power consumption of 89% and 70% respectively, disclosing a real latency-power trade-of between both accelerators.

Filamentary resistance switching, or ReRAM, devices based on oxides suffer from device-do-device and cycle-to-cycle variability of electrical characteristics (electroforming voltages, set and reset voltages, resistance levels and cycling endurance). These are largely materials issues related to the microstructure of the switching oxide. Here we outline strategies to engineer the electrical performance of silicon oxide ReRAM by controlling the oxide microstructure at the nanometre scale through approaches including engineered interfaces and ion implantation. We demonstrate control over the distribution of switching voltages, electroforming voltages, and stable multilevel resistance states.

Interconnect is a crucial challenge to achieve overall chip performance in current and future technology nodes. An accurate, universal, and portable delay model is essential for interconnects’ analysis and coding development. Machine learning algorithms are used in many applications and provide solutions for problems that are difficult to achieve using conventional approaches. Using machine learning techniques for delay estimation can be helpful since they can capture the complex behavior of the propagation of the signals. This paper proposes a neural-network learning-based delay model for parallel multi-segment interconnects using a conventional multi-layer perceptron network. For the network to learn the complex signals’ misalignment effect, we propose a framework to transform initial delay data into a learnable set of numbers. This transformation process is critical to have an accurate delay estimation. The proposed model has been validated using commercial 65 nm technology. The results show significant improvement in accuracy compared with previous models.

To decrease and dampen the vibrations of the seated human bodies in a variety of settings like automobiles and public transportation, control theories and advanced controller design techniques are demanded. In this paper, we approach to design an active multivariable controller for a seated human body model, and results are derived and simulated via MATLAB. After examining the pros and cons of the previous models and strategies for the human body model, it has been decided to design an active controller based on pole placement analysis. This controller is designed for a lumped mass model of the human body with 4 degrees of freedom (4DOF) and with respect to the road excitations’ presence. In the suggested multivariable control strategy, the vertical movements of the four parts of the body are controlled via manipulation of an input force in the vertical direction that is presumed to be applied by a piezoelectric actuator. The dynamic behavior of the system around its natural frequencies is measured and the usefulness of the actuators is investigated.
