Authors: Chavoshisani Reza , Moaiyeri Mohammad Hossein , Hashemipour Omid 
Published: July 2015

Purpose
– Current-mode approach promises faster and more precise comparators that lead to high-performance and accurate winner-take-all circuits. The purpose of this paper is to present a new high-performance, high-accuracy current-mode min/max circuit for low-voltage applications. In addition, the proposed circuit is designed based on a new efficient high-resolution current conveyor-based fully differential current comparator.

Design/methodology/approach
– The proposed design detects the min and max values of two analog current signals by means of a current comparator and a logic module. The comparator compares the values of the input current signals accurately and generates two digital control signals and the logic module determines the min and max values based on the controls signals. In addition, an accurate current copy module is utilized to copy the input current signals and convey them to the comparator and the logic module.

Findings
– The results of the comprehensive simulations, conducted using HSPICE with the TSMC 90 nm CMOS technology, demonstrate the high-performance and robust operation of the proposed design even in the presence of process, temperature, input current and supply voltage variations. For a case in point, for 5 μA differential input current the average propagation delay and power consumption of the proposed circuit are attained as 150 ps and 150 µW, respectively, which leads to more than 64 percent improvement in terms of power-delay product as compared with the most efficient design, previously presented in the literature.

Originality/value
– A new efficient structure for current-mode min-max circuit is proposed based on a novel current comparator design which is accurate, high-performance and robust to process, voltage and temperature variations.
Reducing the impact of ELF electromagnetic fields of HV power cables on the environment by modeling the cable accessories
Authors: Raicevic Nebojsa B. , Raicevic Nikola 
Published: July 2015

Purpose
– Underground cables can produce higher electromagnetic fields directly above them than an overhead line. The majority of cable failures on distribution system are caused by defects in the cable accessories. Nowadays, significant research has been carried out worldwide into examining whether electricity, and in particular, the presence of electric and magnetic fields have an adverse impact on health, especially the occurrence of cancer and childhood leukemia. The purpose of this paper is to optimize the electric field distribution in underground cable accessories. This reduces the impact of the harmful effects of the fields on living beings and humans.

Design/methodology/approach
– Cable terminations and joints are designed to eliminate the stress concentration at the termination screen to avoid the breakdown of the cable and high values of electric field at these points. Any improvement in the cable termination and joints construction is of great interest. There are several methods for the solution of electric field distribution. These can be summarized as analytical, experimental, free-hand field mapping, analogue methods and numerical methods. In this paper cable accessories are modeled by using multilayer dielectric system and very thin deflector’s cones.

Findings
– This model includes specific insulators design and smart choice of electrodes position. Stress-grading nonlinear materials in form of tapes and tubes were used with much success. In order to optimize the cable joint parameters, two criteria were monitored – total electric field magnitude and magnitude of the tangential component. More than 30 percent is reduced impact of cables on the environment.

Originality/value
– In order to investigate the accuracy of the applied numerical model, various configurations of the cable accessories are studied. The first time is applied new Hybrid Boundary Elements Method on the protection of the environment.
Modelling of a bipolar stent-based electrode for thermal radio frequency ablation of tumours located in hollow organs
Authors: Almeida Tony R. , Antunes Carlos L. 
Published: July 2015

Purpose
– In this paper a numerical simulation analysis of a modified stent-based electrode is introduced to be used as a bipolar electrode for radio frequency ablation of tumours located in hollow organs. The purpose of this paper is to study the possibility of achieving a more regular volume of induced lesion with the presented electrode without imperilling the ductal organ where the tumour is located.

Design/methodology/approach
– Three types of bipolar electrode configurations were considered, formed by two, three and five tubular segments. Numerical simulations were performed considering a tumour located in the bile duct, where two important blood vessels – the portal vein and the hepatic artery – have a significant impact due to the convective heat transfer caused by the blood flow (heat sink effect) which significantly affects the shape of lesion that is intended to induce in order to destroy the tumour.

Findings
– The results obtained show that the five-segment electrode arrangement allows a regular volume for the induced lesion, independently of the different values of applied voltage considered.

Originality/value
– The presented work introduces a numerical simulation analysis on a modified based-stent electrode previously studied. In this case, the electrode is configured so it can be used as a bipolar electrode, i.e., active and ground electrode are placed in the same device. Besides the results evinced by the obtained results, this kind of electrode avoids eventual skin burns that might occur due to the need of the return electrodes when monopolar electrodes are used.

Authors: Maheswari R.V. , Vigneshwaran B. , Kalaivani L. 
Published: July 2015

Purpose
– The purpose of this paper is to investigate the condition of insulation in high-voltage equipments using partial discharge (PD) measurements. It proposes the methods to eliminate several noises like white noise, random noise and discrete spectral interferences which severely pollutes the PD signals. The study aims to remove these noises from the PD signal effectively by preserving the signal features.

Design/methodology/approach
– This paper employs fast Fourier transform, discrete wavelet transform and translational invariant wavelet transform (TIWT) for denoising the PD signals. The simulated damped exponential pulse and damped oscillatory pulse with low- and high-level noises and a measured PD signal are considered for this analysis. The conventional wavelet denoising approach is also improved by estimating the automated global optimum threshold value using genetic algorithm (GA). The statistical parameters are evaluated and compared. Among these methods, GA-based TIWT approach provides robustness and reduces computational complexity.

Findings
– This paper provides effective condition monitoring of power apparatus using GA-based TIWT approach. This method provides the low value of mean square error, pulse amplitude distortion and also high reduction in noise level due to its robustness and reduced computational complexity. It suggests that this approach works well for both signals immersed in noise as well as for noise immersed in signals.

Research limitations/implications
– Because of the chosen PD signals, the research results may lack for multiple discharges. Therefore, researchers are encouraged to test the proposed propositions further.

Practical implications
– The paper includes implication for the development of online testing for equipment analysis and diagnostics during normal operating condition. Corrective actions can be planned and implemented, resulting in reduced unscheduled downtime.

Social implications
– This PD-based analysis often present well in advance of insulation failure, asset managers can monitor it over time and make informed strategic decisions regarding the repair or replacement of the equipment. These predictive diagnostics help society to prioritize investments before an unexpected outage occurs.

Originality/value
– This paper provides an enhanced study of condition monitoring of HV power apparatus by which life time of insulation can be increased by taking preventive measures.

Authors: Tabatabaei Mohammad 
Published: July 2015

Purpose
– The purpose of this paper is to present a two-loop approach for velocity control of a permanent magnet synchronous motor (PMSM) under mechanical uncertainties.

Design/methodology/approach

The outer loop employs an RST control structure to compute the q-axis stator reference current. To increase the robustness of the proposed method, the RST controller parameters are adapted through a fractional order model reference adaptive system (FO-MRAS). The fractional order gradient and Lyapunov methods are utilized as adaptation mechanisms.

Authors: Wroblewski Grzegorz , Słoma Marcin , Janczak Daniel , Jakubowska Malgorzata 
Published: July 2015

Purpose
– The aims of this paper are to investigate the influence of direct current (DC) electric field on separation and orientation of carbon nanotubes (CNTs) in spray-coated layers and apply this method to the fabrication of elastic and transparent electrodes. The orientation of CNTs in the form of paths in the direction of electrical conduction should increase the electrode conductivity without decreasing its optical transmission.

Design/methodology/approach
– Materials are deposited using vacuum-free, ultra-fine nozzle spray coating technique, easily applicable for large-scale production. After the deposition of carbon nanomaterials, nanoparticles are oriented in the electric field and initially cured with infrared halogen lamp to evaporate solvents and preserve orientation of the nanoparticles in the deposited layer. Afterwards, layers are cured in a chamber dryer to obtain desired properties. Nanoparticles orientation and carbon nanomaterials separation via DC electric field are analysed, and the optical and electrical properties of prepared electrodes are measured.

Findings
– Experiments described in this paper showed that DC electric field can be applied provide separation and orientation of CNTs and combined with spray coating technique, can be used as additional tool for tuning the conductivity of flexible and transparent electrodes by decreasing the sheet resistance about five times.

Originality/value
– The results showed that spray coating combined with electric field orientation is a promising solution of obtaining elastic and transparent electrodes with oriented carbon particles. According to the authors’ knowledge, none of the experiments was directed to obtain DC electric field-oriented transparent layers produced with the use of spray coating technique.

Authors: Portis Ron 
Published: July 2015

Purpose
– The purpose of this paper is to suggest ways that organizations can foster “interpersonal trust”. The author explores how the implementation of specific strategies can be used to “contextually cue” or “signal” the formation of interpersonal trust.

Design/methodology/approach
– The author reviews two seeming disparate streams of literature: interpersonal trust and the psychology of habit formation. The author shows how the use of “contextual cuing” can be used to create dispositions of trust and how that trust can become an organizational norm, expectation or habit.

Findings
– The author identifies five key steps that can be used to foster interpersonal trust.

Practical implications
– Organizational commitment, knowledge sharing and collaboration and organizational learning have all been shown to have significant impacts on the organization’s bottom line. Given the demonstrable importance of “trust” then must ask, “what can organizations do to more effectively foster interpersonal trust?” The author identifies five key steps that can be used to foster interpersonal trust.

Social implications
– Where there are two or more persons, there is “social interaction”. And, for that interaction to be civil, positive or productive, trust is required.

Originality/value
– There is an abundance of literature regarding the importance of interpersonal trust, organizational trust and their implications. Yet, there is very little that speaks to the operationalization of the concepts with specific and targeted strategies. The author proposes five possible strategies.

The value of mentoring
Authors: Cole Graham 
Published: July 2015

Purpose
– This paper aims to review the latest management developments across the globe and pinpoint practical implications from cutting-edge research and case studies.

Design/methodology/approach
– This briefing is prepared by an independent writer who adds their own impartial comments and places the articles in context.

Findings
– Learning is fundamental to the growth and success of any organization. And any business that fails to comprehend its importance is surely destined for a place among the also-rans. Various possibilities exist where learning and development is concerned. One such option gaining in popularity is mentoring. It has now become recognized as having a key role in the personal and professional development of those participating in such programs. Mentoring typically involves an older person imparting their knowledge and experience to a less worldly individual placed under their guidance. Enabling the “mentee” to learn thus tends to be the main objective of these arrangements.

Practical implications
– The paper provides strategic insights and practical thinking that have influenced some of the world’s leading organizations.

Originality/value
– The briefing saves busy executives and researchers hours of reading time by selecting only the very best, most pertinent information and presenting it in a condensed and easy-to-digest format.
