The need for electronic devices usage has risen significantly over the years. This has in turn generated greater demands for electricity and in addition for green energy sources. These include Radio-Frequency (RF) energy harvesting. In this concept we design a rectifier circuit for RF to DC conversion suitable for operation at sub-6 GHz 5G bands. Such a circuit can be used to supply low-power electronic devices. The proposed rectifier works at the frequency band FR1 of 5G cellular network and more specifically at 3.5 GHz. The most important problem in the RF energy harvesters is low system efficiency, something that limits the popularity of the power harvest. The proposed design is found to be highly efficient in its current form. Numerical results show that the system in a single-tone signal provides maximum power conversion efficiency equal to 42.5% when the load of the circuit is 1.1 KΩ and the input power reaches 9 dBm. The presented rectifier circuit performs better or equally with similar designs in the literature.

Computation based on the von Neumann architecture suffers from the data transfer between computation unit and memory, i.e. the so-called von-Neumann bottleneck. Thus, new computing paradigms emerge leveraging in-memory computing (IMC). Stateful memristor aided logic (MAGIC), which has attracted great attention in recent years, enables the realization of a functionally complete set of Boolean logic functions within a memristive memory array. Whereas typically digital-switching memristive devices are exploited, in this work, we investigate the realization of MAGIC gates using analog-switching BiFeO3 (BFO) devices. The simulation results reveal that the MAGIC NIMP gates, as proposed for a digital-switching memristive device, do not work correctly with the analog BFO devices. By studying the input drift and blocking effect while operating MAGIC NIMP gate, we propose two alternative MAGIC gates by exploiting analog memristors, i.e. a NOR gate and a -P gate.

It is widely known and accepted in the medical field that accurate medication treatment is crucial for patient’s outcome, especially amongst patients with chronic diseases. According to World Health Organization (WHO), low level of medication adherence leads to increased mortality rate and immense medical costs. Important research efforts have been dedicated to finding an objective way to assess and increase the level of medication adherence. The aim of the Smart-Blister project is to study, design and develop a novel methodology, which uses electronic circuits embedded in the blisters to detect the exact time that a pill has been removed. The proposed methodology consists of (a) a smart blister with a passive electronic circuit directly screen printed onto the blister or onto a self-adhesive substrate (smart-label approach) using a conductive ink, and (b) a small electronic device, that activates the blister and communicates with a central information cloud computing system. The proposed design can be easily adopted and allow for potentially scalable production of low-cost smart blisters. Moreover, the activation device is reusable, can be used with various blisters and it is expected to be of low-cost.

In this paper we propose an iterative receiver architecture. The proposed architecture estimates the channel using a weighted function which combines both the coefficients estimated by the known pilot sequence and the decoded bit stream. This approach grants a performance boost of 1.5–2 dB in low bit error rates with the trade-off of more hardware resources utilized. A second, more complex architecture has been evaluated, but discarded as it does not produce any noticeable benefit.

A lookup table-based check and variable node are considered for designing low-density parity check (LDPC) decoder architectures, using the principle of the information bottleneck method. It has been shown that an information bottleneck LUT operation can outperform conventional minsum arithmetic operation in terms of error-correction capability. This paper presents a cost-efficient hardware implementation of LUT-based node processing units in the decoder architecture. It exploits the symmetry of the communication channel and multi-input LUT decomposition to generate a reduced-size LUT structure. The LUT operations are designed as a two-level memory subsystem enabling LUT mappings reconfiguration at runtime. As a case study, a rate-7/10 7650-bit regular QC-LDPC decoder is implemented on an FPGA, achieving a throughput of up to 1.345 Gbps at 10 iterations. Compared with the conventional offset min-sum decoder, the proposed decoder increases the throughput-to-area ratio up to 39.22% at a cost of no more than 0.08 dB decoding performance loss. In addition, the hardware complexities of node design variants are investigated.

As the world advances it becomes increasingly technology-dependent, bringing together infrastructure and technology to improve the quality of life for the citizens. Smart cities have become the future of urbanization. Since the priority of a city is to protect its citizens, a video surveillance system is required to ensure their safety. This paper proposes a multi-camera cloud-Edge surveillance system for smart cities and homes. Multiple units of Raspberry Pi act as the Edge Computing device that streams and summarizes the processed video footage. After summarizing the video to reduce its length and size, it sends the videos to the cloud (virtual machine). The cloud applies resource-intensive computer vision algorithms such as detecting motion, objects including humans, weapons, and fire. Furthermore, it manages the recorded surveillance videos, stores them in the database, and alerts the user if a threat occurs. The experimental results show that the time taken to perform these tasks was reduced by an average of 83% for the object detection models.

This work presents experimental results from an integrated low-power, low-area Dickson charge pump circuit, using 7.5 mm2 miniature photovoltaic cells, for cold-start operation. The proposed cold-start topology presents successful operation, both for indoor and outdoor lighting conditions, for input voltages as low as 440 mV. The cold-start circuit is implemented and fabricated in a 0.18 um CMOS process. The chip active area, occupied by the designed cold-start block, is 0.224 mm2. The area-efficient and low-power design of the presented cold-start circuit makes it ideal for micro-energy harvesting applications.

The studies performed by the authors on Virtusphere (VS) platform led to identify solution to improve the feeling of immersion provided by a virtual environment. It was concluded in a previous paper that this feeling could be achieved by upgrading the VS with a mechatronic system. First experiments were performed using one brushless DC (BLDC) motor to determine if the actuation method and the control strategy suit application requirements. These were validated by comparing the results of the MATLAB / Simulink simulations with the practical results. To further enhance the system’s effectiveness, the authors propose an additional actuator. This paper presents improvements to the drive mechatronic system for Virtusphere (DMSVS) and a strategy to synchronize the two motors with the user’s movement. Using two in-wheel motors to reduce power transmission elements, a series of experiments were performed to implement the synchronization equations. At the end of this article will be presented the results of these experiments and conclusions about the control algorithm with simple wheels and with the new omnidirectional wheel design developed by the authors.

In this paper, the performance of Energy and Cyclo-stationary spectrum detection in Rayleigh, Nakagami, Rician, and additive white gaussian noise (AWGN) channel environments is investigated for spectrum sensing in cognitive radio networks. MIMO-OFDM cognitive radio (CR) system is used where CR devices continuously sense the channel to check whether it is idle or not using compressed sensing with cyclo-stationary detection, and reconstruct the signal if communication is available for the given CR receiver from its transmitter. Moreover, collaborative spectrum sensing improves performance degradation caused by multipath and shadowing.

Artificial insemination is the main method used for sows’ fertilization in pig farms. Therefore, boar fertility is a key parameter of the economic efficiency of a livestock company. Stress (e.g., thermal) influences both libido and semen characteristics, and might be the reason for "seasonal infertility", which negatively affects the economic status of pig farms. In this work we show that overall dynamic body acceleration (ODBA) derived by accelerometer data from boars during the semen collection process is correlated to both ambient and body temperature. It may also provide useful information about a boar’s sexual behavior and, hopefully, fertilization efficacy, but further research is necessary on this issue.
