Cagniard-Dehoop Technique-Based Computation Of Retarded Partial Coefficients: The Coplanar Case, Martin Stumpf, Giulio Antonini, Albert E. Ruehli Jan 2020

Cagniard-Dehoop Technique-Based Computation Of Retarded Partial Coefficients: The Coplanar Case, Martin Stumpf, Giulio Antonini, Albert E. Ruehli

Electrical and Computer Engineering Faculty Research & Creative Works

Efficient computation of partial elements plays a key role in the Partial Element Equivalent Circuit (PEEC) method. A novel analytical method for computing retarded partial coefficients based on the Cagniard-DeHoop (CdH) technique is proposed. The methodology is first theoretically developed and then illustrated on the computation of a surface retarded partial coefficient pertaining to two coplanar rectangular surface elements. An efficient way for incorporating loss mechanisms in the time domain (TD) via the Schouten-Van der Pol theorem is proposed. Illustrative numerical examples demonstrating the validity of the introduced solution are given.

On The Effects Of High-K Dielectric Resurf In High-Voltage Bulk Finfets, Chia Hui Cheng, Jun Wei Lai, Kai Ting Hu, Chih Fang Huang, Feng Zhao Jan 2020

On The Effects Of High-K Dielectric Resurf In High-Voltage Bulk Finfets, Chia Hui Cheng, Jun Wei Lai, Kai Ting Hu, Chih Fang Huang, Feng Zhao

Electrical and Computer Engineering Faculty Research & Creative Works

High-K dielectric reduced surface field (RESURF) effects in high-voltage bulk FinFETs through three-dimensional simulation are discussed in this paper for the first time. Compared to a planar gate LDMOSFET where the length of the drift region is the same, dielectric RESURF significantly increases the optimal implant dose for the drift region to a higher value, although BV2/Ron,sp is similar. By using a high-K dielectric in the shallow trench isolation (STI) to further enhance the dielectric RESURF, the BV is increased and the Ron,sp is reduced, yielding a significantly improved BV2/Ron,sp, together with a better ON/OFF current ratio. However, with the …

The Sixth Sense That Gives Burdens: Narratives And Explanations On The 'Gifted People's Encounters With The Supernatural, Ratna Andriani Fabrian Jan 2020

The Sixth Sense That Gives Burdens: Narratives And Explanations On The 'Gifted People's Encounters With The Supernatural, Ratna Andriani Fabrian

Antropologi Indonesia

In Jakarta, stories of people experiencing ghosts were not uncommon or peculiar. For some people, a given sixth sense allows them to gain advantages by communicating with the supernatural—this is considered as a gift. But, this ‘gift’ carries a side-effect, that is, the bearers may often get disturbed by ghosts due to their own supernatural sensitivity. To protect themself from supernatural disturbances, the bearers have to refrain from committing certain actions and have to constantly and solemnly pray. However, if they find the disturbances unbearable, they may visit a spiritual healer who has more power in controlling the supernatural. This …

Research outputs 2014 to 2021

Introduction More than 30 million adults are released from incarceration globally each year. Many experience complex physical and mental health problems, and are at markedly increased risk of preventable mortality. Despite this, evidence regarding the global epidemiology of mortality following release from incarceration is insufficient to inform the development of targeted, evidence-based responses. Many previous studies have suffered from inadequate power and poor precision, and even large studies have limited capacity to disaggregate data by specific causes of death, sub-populations or time since release to answer questions of clinical and public health relevance. Objectives To comprehensively document the incidence, timing, …

The Influence Of Santería In Leo Brouwer's Solo Guitar Works (1955–1993), Eoin Flood Jan 2020

The Influence Of Santería In Leo Brouwer's Solo Guitar Works (1955–1993), Eoin Flood

Doctoral

This study will assess the solo guitar works of Cuban composer Leo Brouwer (1939–present) in terms of influence from Santería, a ritual music derived from WestAfrican slaves and still practised in Cuba. This will be achieved by using both analytical and evaluative processes. For the former, a range of influential parameters have been identified, each falling under three strands: rhythmic and metric, structural, and melodic. These will be revealed in all of Brouwer’s solo guitar works written from 1955 to 1993. A parameter’s influence can be revealed in two ways: the multitude of its usage per piece, or the percentage …

Framing “L’Âme Des Personnages”: Performance And Affect In Jacques Feyder’S Pension Mimosas (1935), Barry Nevin Jan 2020

Framing “L’Âme Des Personnages”: Performance And Affect In Jacques Feyder’S Pension Mimosas (1935), Barry Nevin

Articles

Although Jacques Feyder's authorial control over his productions and his direction of actors constituted two of the most widely appreciated aspects of his approach to filmmaking during his own lifetime, the impact of each on his mise en scene has received little critical attention. This article aims to remedy this oversight by linking both aspects in three stages: first, drawing on contemporary periodicals, recollections of Feyder's performers and his own writings, it illustrates Feyder's preoccupation with the creation of in-depth psychological portraits through his actors; second, focusing on Pension Mimosas (1935), it demonstrates that Feyder's technical style, although aligned closely …

Smart Green Communication Protocols Based On Several-Fold Messages Extracted From Common Sequential Patterns In Uavs, Iván García-Magariño, Geraldine Gray, Raquel Lacuesta, Jaime Lloret Jan 2020

Smart Green Communication Protocols Based On Several-Fold Messages Extracted From Common Sequential Patterns In Uavs, Iván García-Magariño, Geraldine Gray, Raquel Lacuesta, Jaime Lloret

Articles

Green communications can be crucial for saving energy in UAVs and enhancing their autonomy. The current work proposes to extract common sequential patterns of communications to gather each common pattern into a single several- fold message with a high-level compression. Since the messages of a pattern are elapsed from each other in time, the current approach performs a machine learning approach for estimating the elapsed times using off-line training. The learned predictive model is applied by each UAV during flight when receiving a several-fold compressed message. We have explored neural networks, linear regression and correlation analyses among others. The current …
