Enhanced Mathematical Modelling of Interior Permanent Magnet Synchronous Machine Considering Saturation, Cross-Coupling and Spatial Harmonics effects

2020

The Interior Permanent Magnet Synchronous machine (IPMSM) conventional mathematical model is generally employed to investigate and simulate the IPMSM control and drive system behaviour. However, magnetic nonlinearities and spatial harmonics have a substantial influence on the IPMSM electromagnetic behaviour and performances. In order to simulate the IPMSM real electromagnetic behaviour, this paper describes an enhanced mathematical model that takes into account the saturation, cross-coupling and spatial harmonics effects. This model has been implemented in Matlab®/Simulink environment where the electric and magnetic parameters are derived from FEA investigations and implemented by the use o…

The molecular characterization of a depurinated trial DNA sample can be a model to understand the reliability of the results in forensic genetics

2014

The role of DNA damage in PCR processivity/fidelity is a relevant topic in molecular investigation of aged/forensic samples. In order to reproduce one of the most common lesions occurring in postmortem tissues, a new protocol based on aqueous hydrolysis of the DNA was developed in vitro. Twenty-five forensic laboratories were then provided with 3.0 μg of a trial sample (TS) exhibiting, in mean, the loss of 1 base of 20, and a molecular weight below 300 bp. Each participating laboratory could freely choose any combination of methods, leading to the quantification and to the definition of the STR profile of the TS, through the documentation of each step of the analytical approaches selected. …

Stereo to Wave-Field Synthesis music up-mixing: An objective and subjective evaluation

2008

Sound source separation techniques are known to be very useful in many applications. High fidelity and audio oriented applications are a challenging issue in this topic, however, existing algorithms are far from performing with such a high quality. In this paper, a subjective and objective evaluation are carried out for several algorithms designed for dealing with stereo music mixtures. The performance of these algorithms applied to acoustic scene resynthesis in a Wave Field Synthesis system is discussed.

Impact of LTE’s Periodic Interference on Heterogeneous Wi-Fi Transmissions

2018

The problem of Wi-Fi and LTE coexistence has been significantly debated in the last years, with the emergence of LTE extensions enabling the utilization of unlicensed spectrum for carrier aggregation. Rather than focusing on the problem of resource sharing between the two technologies, in this paper, we study the effects of LTE's structured transmissions on the Wi-Fi random access protocol. We show how the scheduling of periodic LTE transmissions modifies the behavior of 802.11's distributed coordination function (DCF), leading to a degradation of Wi-Fi performance, both in terms of channel utilization efficiency and in terms of channel access fairness. We also discuss the applicability and…

Seabirds mated for life migrate separately to the same places: behavioural coordination or shared proximate causes?

2015

Long-term pair bonds occur in diverse animal taxa, but they are most common in birds, and can last from a few years to a lifetime. In many of these species, after the reproductive season, birds migrate to distant nonbreeding grounds where they remain for several months, and until recently, little was known about whether partners maintain contact during migration. This gap in knowledge was primarily due to past methodological difficulties in tracking long-term, large-scale movements of individuals. However, the development of new animal-borne geolocation devices has enabled researchers to track movements of individuals for a year or more. We tracked the annual migrations of both members of b…

Castron kastraatio : Pedro Juan Gutiérrezin proosa castrokommunistisen utopian romuttajana

2016

This dissertation explores how Pedro Juan Gutiérrez's fiction corresponds to the Castrocommunist utopia. The study has three goals: (1) to explain how Castro-communism has formed, altered and impacted on Cuban literature; (2) to investigate how Gutiérrez's fiction corresponds to the Castro-communist utopia and ideals; and (3) how his parodic (anti)detective story Nuestro GG en La Habana (2004) is based on and relates to Cuban socialist detective stories, Graham Greene's spy farce Our Man in Havana, Castro-communist historiography and the social, ideological and economic shifts in Cuban society during the 1990s. Previous studies on Gutiérrez's fiction have focused almost exclusively on the a…

Can't simply roll it out: Evaluating a real-world virtual reality intervention to reduce driving under the influence.

2020

Driving under the influence (DUI) increases the risk of crashes. Emerging technologies, such as virtual reality (VR), represent potentially powerful and attractive tools for the prevention of risky behaviours, such as DUI. Therefore, they are embraced in prevention efforts with VR interventions primed to grow in popularity in near future. However, little is known about the actual effectiveness of such DUI-targeting VR interventions. To help fill the knowledge gap, this study explored the effects of one VR intervention as delivered in the real world. Using pre and post test design, including an intervention group (n = 98) and a control group (n = 39), the intervention evaluation examined you…

Natural history of the Sprint Fidelis lead: survival analysis from a large single-center study.

2012

The purposes of our study were to: (1) determine lead failure rate in a large single-center cohort of Sprint Fidelis 6949 (Fidelis) leads, (2) define the risk of lead failure over time, (3) assess the impact of the Lead Integrity Alert (LIA) on lead failure presentation, and (4) identify independent predictors of Fidelis lead failure. All patients who underwent implantation of a Fidelis lead between September 2004 and July 2007 were included. Demographic, clinical, and device characteristics at the time of implant and prior to failure were collected and analyzed. A total of 971 Fidelis leads (706 men, 265 women, mean age 68.4 ± 12.8 years) were implanted. Over a mean follow-up of 46.3 month…

Learning From Errors: Detecting Cross-Technology Interference in WiFi Networks

2018

In this paper, we show that inter-technology interference can be recognized using commodity WiFi devices by monitoring the statistics of receiver errors. Indeed, while for WiFi standard frames the error probability varies during the frame reception in different frame fields (PHY, MAC headers, and payloads) protected with heterogeneous coding, errors may appear randomly at any point during the time the demodulator is trying to receive an exogenous interfering signal. We thus detect and identify cross-technology interference on off-the-shelf WiFi cards by monitoring the sequence of receiver errors (bad PLCP, bad FCS, invalid headers, etc.) and propose two methods to recognize the source of in…
