The implementation of microwave and millimetre-wave switching networks using phase change material (PCM) is presented in this paper. We propose integrating a combination of ultra-wide bandwidth-optimised building cells into a unique semi-T type switch. The construction of arrays with different dimensions is enabled.

Abstract Thermally switchable building envelopes can provide energy savings compared to their traditional static counterparts. For example, in the summertime cooling season the envelope can switch into a thermally conductive state at night to exploit the free cooling of the nighttime air, while switching back into a highly insulating state during the warm daytime. Further benefits can be realized by incorporating phase change materials (PCMs) into the same building envelope between two thermal switches, because the PCM can store that nighttime cooling for later use during the day.

Abstract This paper presents the results of experimental research of a resonant switched capacitor voltage multiplier in a cost-effective topology (CESCVM) with a limited number of active switches. In the charging mode of the switched capacitors, the converter utilizes only one active switch and a required number of diodes. Therefore, the cost of the converter is decreased as compared with that of a classical SCVM converter, owing to a lower number of switches and gate driver circuits, as well as a smaller PCB area. Moreover, the CESCVM has simpler control circuits and higher reliability. This

Critical to coordinating gene expression with the process of differentiation, the activity of PREs can be switched “on” and “off.” When on, the PRE imposes a silenced state on the genes in the same domain that is stably inherited through multiple rounds of cell division. When the PRE is switched off, the domain is in a state permissive for gene expression that can be stably inherited. Previous studies have sugges

In this research work, we investigated a dual switch (DS) active rectifier for the piezoelectric (PE) energy scavenging system. In the proposed DS active rectifier configuration, two extra switches are shunted across the PE transducer which helps the PE transducer’s capacitor in charging and discharging which results in maximum power extraction from the PE transducer. Moreover, in the proposed rectifier configuration comparator controlled active diodes are used instead of conventional/passive diodes to minimize the threshold voltage V T H drop. The proposed DS active rectifier design is fabric

The operation of multidomain and multivendor EONs can be achieved by interoperable sliceable bandwidth variable transponders (S-BVTs), a GMPLS/BGP-LS-based control plane, and a planning tool. The control plane is extended to include the control of S-BVTs and elastic cross connects, which combine a large port-count fiber-switch (optical backplane) and bandwidth-variable wavelength-selective switches, enabling the end-to-end provisioning and recovery of network services. A multipartner testbed is built to demonstrate and validate the proposed end-to-end architecture. Interoperability among S-BVT

Phase Change Memory (PCM) has evolved as a promising alternative over Dynamic Random Access Memory (DRAM) in terms of cell density and leakage power. While non-volatility is a desirable feature, it gives rise to the possibility of the data being present even after the power is switched off. To secure the data, encryption is normally done by using the standard Advanced Encryption Standard (AES) algorithm. Encrypting the data results in huge number of bit-flips, which reduces the lifetime of a PCM. The proposed method increases the lifetime of PCM by reducing the number of bit-flips occurred due

Abstract The absorption of L-thyroxine (L-T4) can be affected by different factors, such as the manner of L-T4 assumption (during breakfast, or with food), the age of the patient, the interference with other drugs, absorption kinetics, adherence to therapy, and others. L-T4 tablets malabsorption can occur due to the increased gastric pH in patients in treatment with proton pump inhibitors (PPI; omeprazole, pantoprazole, lansoprazole) for gastritis, gastric ulcer, etc. We enrolled 25 patients in treatment with L-T4 in the tablet formulation, and with elevated serum thyroid-stimulating hormone (

Thermal management of electronics is quite important for safe operation of nuclear rescue robot. However, the ambient temperature of the nuclear robot in the site of nuclear accident will suffer an alternation between ordinary and elevated temperature. Traditional phase change material (PCM) based closed scheme for thermal protection is not suitable due to the capacity limitation of PCM. Open scheme with forced air cooling or water cooling is not acceptable either, because it cannot operate in high temperature. Therefore, a semi-open thermal control scheme is proposed by using silica aerogel f

In this paper, we present a CMOS full-wave rectifier with comparator-controlled switches for transmission of wireless power in implantable medical devices. It uses MOS transistors as low loss switches to provide high power conversion efficiency (PCE). The proposed fast comparator circuit, by controlling the switches in the rectifier, reduces the reverse leakage current in the negative cycle and increases the conduction time in the positive cycle so that more current flows into the output load and optimizes the rectifier power efficiency. The designed comparator does not require constant voltag

The demand for high-gain, efficient, and cost-effective power converters with simple control mechanisms to connect electric vehicle batteries to the grid is increasing. This study introduces a switched capacitor-based power boost converter circuit to meet these needs. The minimal number of power switches in the circuit simplifies control operations and improves practical applicability. The proposed converter boosts the battery pack voltage by a factor of 5 and 11 for duty ratios of 0.5 and 0.8, respectively, which is significant compared to conventional boost converters.
