The paper proposes an approach to investigate the fine structure of the voltages circulating in the industrial network within the range of 300 kHz-20 MHz, which serves to do some measurements of real lines in real operating mode. It is shown that the interferences can be divided into basic with spectral density changing slowly with frequency alteration and narrow-band (frequency-pulse). It is...

In this letter, novel class-F and inverse class-F power amplifier (PA) topologies were proposed, simulated, realized and measured for 2.7–2.9GHz frequency band by using Gallium Nitride high electron mobility transistor (GaN HEMT). Realizations are made on Rogers TMM3 dielectric material which has 0.381mm thickness and 3.27 dielectric constant. Proposed class-F and inverse class-F PAs have 10W (...

The regulation on power line communication (PLC) has been eased in Japan, and the frequency band between 2 and 30 MHz can be used for in-home PLC. Several different types of commercial PLC equipment are available in the market. Almost all of them include PLC adapters that interconvert Ethernet signals and power line signals. An in-home network can easily be constructed by using these PLC adapte...

A low phase noise, low dissipated power and small sized Ka-band voltage-controlled oscillator (VCO), using dual cross-coupled pair configuration and capacitance-splitting technique is presented. The Ka-band VCO circuit uses 0.15 μm GaAs pHEMT technology. The VCO has low phase noise, of 116.36 dBc/Hz, at a 1 MHz offset and can be tuned from 30.5 to 31.22 GHz. The figure of merit (FOM) is -192.36...

Several demand response (DR) strategies rely on real-time pricing and selfish local optimization, which may not result in optimal electricity consumption patterns from the viewpoint of an energy supplier or a power system. Thus, this paper proposes a strategy enabling centralized adjustments to cost-minimize consumers’ load. By employing the strategy, an aggregator is able to alter electricity ...

A multi-band CMOS LC Quadrature Voltage Control Oscillator (QVCO) with minimum power consumption is developed to meet the phase noise and frequency band requirements of RFID, Zigbee and Bluetooth standards. To accomplish the multi-band receiving architecture at low power consumption, current switching technique with optimized cross-coupled transistor sizes has been used. A comprehensive analysi...

Powerful constraints on theories can already be inferred from existing CMB anisotropy data. But performing an exact analysis of available data is a complicated task and may become prohibitively so for upcoming experiments with & 10 pixels. We present a method for approximating the likelihood that takes power spectrum constraints, e.g., “band-powers”, as inputs. We identify a bias which results ...

Experimental results on 60GHz band signal transmission through ECOR (Electromagnetic Coupling of Open-Ring Resonators) are shown. Through 200μm sapphire substrate, 60-70GHz band signal are transmitted with 58.9% transmission efficiency and 7.4GHz bandwidth. However, the transmission band was shifted about 10GHz higher frequency. The reason is under investigation. ECOR technology is extended to ...

In this document, the Commission seeks comment on how to amend its rules to implement certain provisions of the Local Community Radio Act of 2010 (‘‘LCRA’’) that are not already the subject of Commission action. It also proposes changes to its rules intended to promote the low power FM service’s localism and diversity goals, reduce the potential for licensing abuses, and clarify certain rules.

We consider the lacunary Dirichlet series obtained by taking the reciprocals of the s-th powers of the Fibonacci numbers. This series admits an analytic continuation to the entire complex plane. Its special values at integral arguments are then studied. If the argument is a negative integer, the value is algebraic. If the argument is a positive even integer, the value is transcendental by Neste...
