Learning to let go – the Charter of Fundamental Rights after Brexit

The UK Government’s proposal that the Charter of Fundamental Rights of the EU (the Charter) will not be converted into UK law following Brexit (clause 5(4) of the EU Withdrawal Bill) has generated strong reaction from opposition parties. The Labour party has indicated that it considers this to be a ‘red-line’ issue, and that it will not support a bill that does not incorporate the charter into UK

A Fundamental Right to Tax Enforcement? A response to Prof. Capaldo

In a previous entry, Prof. Capaldo criticised the judgment of the Court of Justice of the EU in Taricco II by arguing that there exists, in international law (or what the author calls ‘global law’), a fundamental human right to policies that criminalise tax fraud. According to the author, the Court presented in its judgment a false dichotomy between the need to ensure the effective application of

A Tri-band, small size radio frequency identification tag antenna with u-shaped slots

A new multiband, small size antenna for passive radio frequency identification (RFID) tags is presented. Placement of three U-shaped slots can create three independent resonances within the RFID range: 0.953, 2.45, and 5.8 GHz, whereas in each resonance, particular inductive input impedance will be achieved by a simple technique to be conjugately matched with the capacitive impedance of the chosen

Accurate Time - Domain Modeling of Multi-Finger pHEMT layout Structure based on Transmission line Theory

In this paper, a fully distributed modeling of double gate InGaAs pHEMT as a 5-line active coupled transmission line is described. In order to apply the transmission line theory, a proper equivalent lumped circuit model is allocated for the differential length of the double gate quintuple line transistor and the active multi-conductor transmission line equations are obtained. The passive element v

The changing face of ethics : Developing a code of ethics for professional accountants from 1977 to 2006

This article aims to contextualise the development of the Code of Ethics for Professional Accountants by the International Federation of Accountants (IFAC) between 1977 and 2006. Drawing on transnational regulation literature, an extensive review of archival documents was conducted. The analysis unfolds the development of the Code in an increasingly complex regulatory environment, revealing the dy

An ANN-based Versatile Millimeter-wave MIMO Slotted Patch Antenna for 5G Network

This study addresses the modelling of a dual band (28 and 38 GHz), circularly polarised slotted-patch-antenna for highly demanded millimetre wave multi-input multi-output (MIMO)-systems in fifth generation (5G) networks. A computer-aided-design model is derived by means of an artificial neural network (ANN) which allows obtaining the physical dimensions of a single-fed antenna, satisfying both nea

Large-signal and Distributed-based Model of mm-wave Multi-Finger pHEMTs using Time-Domain Technique

The finite-difference time-domain (FDTD) method is used for the large-signal modeling of a multifinger pHEMT, which is considered as five nonlinear coupled distributed transmission lines. The developed model, which is based on the exact physical layout of multifinger pHEMT, not only accurately describes the propagation effects along the electrodes at higher frequencies but it also includes major n

A single feed dual-band circularly polarized millimeter-wave antenna for 5G communication

In this paper, one simple dual-band (28 and 38 GHz) circularly polarized slotted patch antenna, suitable for future millimeter wave mobile communication, is presented. The proposed monolayer circularly polarized patch antenna is considered without any 90° phase shifter and is excited by a single-feed microstrip line, which is very desirable for high gain antenna array implementation in millimeter

Performance investigation of space diversity for a 28/38 GHz MIMO antenna (applicable to mm-wave mobile network)

A multiple-input-multiple-output (MIMO) dual-band antenna system consisting of two elements, each of which built up of circularly polarized slotted patch antenna for mm-wave band 5G wireless handheld and portable terminals is described. Space diversity is used to achieve a good independent channel fading in MIMO systems. In theoretical analysis of MIMO systems often assume that each antenna is iso

A Continues 360° CMOS phase shifter for 60GHz phased array applications

The overall designing of one 90nm CMOS reflective-type phase shifter for the first three channels in 60 GHz band is described. The performance investigation is based on full wave electromagnetic analysis and optimization. The simulation predicts a phase tuning range of 360° as a function of control voltage with an average insertion loss of 5.5 dB over all phase states. The linearity of the phase s

Design and hybrid analysis of an integrated 60 GHz active phased array transmitter using a power amplifier and 360° phase shifter

The overall circuit designing of one path phased array transmitter consisting of 90 nm CMOS integrated power amplifier and passive phase shifter for the first three channels in 60 GHz band, is described. The performance investigation is based on a hybrid analysis and optimization. It consists of both electromagnetic (Method of Moments (MOM)) analysis for improving the accuracy of the models in thi

Concurrent Dual-Band Power Amplifier using Coupling Matching Network for 60 GHz WPAN Applications

A new fully-integrated concurrent dual band CMOS power amplifier (PA) which covers the first and third channels of IEEE 802.15.3c standard is presented. In order to achieve concurrent operation of the 60 GHz PA in two desired narrow frequency bands, the multi-frequency passive coupling matching networks design is proposed. The full wave electromagnetic analysis (by the conventional Method of Momen

Specific Support to Lithuania - Fit for the future : Incentivizing research and innovation partnerships and attracting innovative investment to Lithuania

It aims to support Member States and associated countries in improving their national science, technology and inn

Developmental Universities in Inclusive Innovation Systems : Alternatives for Knowledge Democratization in the Global South

This book analyzes the current trends in the production, dissemination, and use of knowledge which contribute to social inequalities, especially in the Global South. The aim of the text is to explore the possibilities of active involvement by universities in the democratization of knowledge - a process by which people will be able to more easily acquire and utilize knowledge, as well as the result

In Operando X-Ray Nanodiffraction Reveals Electrically Induced Bending and Lattice Contraction in a Single Nanowire Device

Hard X-ray diffraction (XRD) using a nanofocused beam is used to measure both lattice contraction and bending in a single nanowire device under electric bias. The shape of the nanowire is reconstructed in 3D with sub-nanometer precision. As the bias voltage is gradually increased, nonreversible structural changes in the contact regions are observed, correlated with degradation of the electrical co

Simultaneous high-resolution scanning Bragg contrast and ptychographic imaging of a single solar cell nanowire

Simultaneous scanning Bragg contrast and small-angle ptychographic imaging of a single solar cell nanowire are demonstrated, using a nanofocused hard X-ray beam and two detectors. The 2.5 μm-long nanowire consists of a single-crystal InP core of 190 nm diameter, coated with amorphous SiO2 and polycrystalline indium tin oxide. The nanowire was selected and aligned in real space using the small-angl
