Modelling and Simulation of Strengthening in Complex Martensitic 9 12% Cr Steel and a Binary Fe Cu Alloy
Year: 2010

Modern martensitic 9 12% Cr steels are alloys with excellent mechanical properties even at elevated temperatures. The high temperature strength of these materials is inevitably related to their complex microstructure in the 'as received' condition. Due to diffusional processes however, this microstructure changes during high temperature service, which leads to a decrease in strength. To identify the impact of changing microstructure on the mechanical properties of an investigated material, a new methodology to model strengthening in steel is developed and presented in this dissertation. A microstructure property link is formulated with focus on the precipitate and solid solution hardening effect. Also, additional strengthening effects, i.e. from the grain and subgrain structure, as well as dislocation strengthening are critically assessed. The developed strength module is applied on a two component Fe Cu alloy with 1.4at. Cu and a complex 11% Cr steel (COST E2) to determine the evolution of the lower yield stress or rather 0.2% proof stress of these alloys. For different heat treatments, the numerical results are compared with experimental results. The numerical simulation shows excellent agreement in the case when all operative strengthening mechanisms are duly considered. Furthermore, the role of precipitates on the creep rupture strength evolution in martensitic steels is critically discussed based on two numerical studies on the potential of heat treatment optimization to increase creep strength and precipitation reactions during service. It is shown that the evolution of precipitation parameters, i.e. size and number density of the second phase particles, significantly influences the evolution of the overall creep strength. For this, the calculated precipitate back stress is compared to the creep rupture strength of the investigated alloys. The experimental results can be reproduced in a comprehensive and consistent manner by the numerical simulations using the software MatCalc.

REVIEW PAPER: Emerging and Reemerging Infectious Diseases of Nonhuman Primates in the Laboratory Setting
Venue: Veterinary pathology
Year: 2010

Despite numerous advances in the diagnosis and control of infectious diseases of nonhuman primates in the laboratory setting, a number of infectious agents continue to plague colonies. Some, such as measles virus and Mycobacterium tuberculosis, cause sporadic outbreaks despite well established biosecurity protocols, whereas others, such as retroperitoneal fibromatosis associated herpesvirus, have only recently been discovered, often as a result of immunosuppressive experimental manipulation. Owing to the unique social housing requirements of nonhuman primates, importation of foreign bred animals, and lack of antemortem diagnostic assays for many new diseases, elimination of these agents is often difficult or impractical. Recognition of these diseases is therefore essential because of their confounding effects on experimental data, impact on colony health, and potential for zoonotic transmission. This review summarizes the relevant pathology and pathogenesis of emerging and reemerging infectious diseases of laboratory nonhuman primates.
Preoperative angiography and external carotid artery embolization of juvenile nasopharyngeal angiofibromas in a tertiary referral paediatric centre.
Venue: Clinical radiology
Year: 2013

To evaluate the relationship between intraoperative blood loss and juvenile nasopharyngeal angiofibroma (JNA) vascular supply and tumour stage in patients who underwent superselective external carotid artery (ECA) embolization. This series is unique in that all embolizations were performed by dedicated paediatric interventional radiologists at a tertiary referral paediatric centre.  Seventeen male patients treated from January 2002 to August 2009 underwent preoperative angiography and embolization using polyvinyl alcohol (PVA) particles. Tumours were graded using three different staging systems based on preoperative imaging and correlated to surgical blood loss. All patients underwent bilateral internal and external carotid angiography, with embolization of ECA tumour supply via microcatheter delivery of PVA particles. Particle size ranged from 150 500 mm with a mean size of 250 355 mm. Surgical resection was performed with either endoscopic or open techniques within 24 h and intraoperative blood loss was reported.  Seven lesions were supplied strictly by the ECA circulation and had mean surgical blood loss of 336 ml. Twelve lesions had both ECA and internal carotid artery (ICA) supply and had mean surgical blood loss of 842 ml. The difference in blood loss in these two groups was statistically significant (p 0.03) There was no case of inadvertent intracranial or ophthalmic embolization. There were statistically significant correlations between estimated surgical blood loss and the Andrews (p 0.008) Radkowski (p 0.015) and University of Pittsburgh Medical Center (UPMC; p 0.015) preoperative tumour staging systems, respectively.  Preoperative embolization of JNA tumours can be safely performed without neurological complications. The present study identified a statistically significant difference in intraoperative blood loss between those lesions with a purely ECA vascular supply and a combination of ECA and ICA vascular supply. Angiography is helpful in delineating ICA supply and can help guide surgical planning.
TRLs 5 7 Advanced Manufacturing Centres, Practical Model to Boost Technology Transfer in Manufacturing
Venue: Sustainability
Year: 2019

Establishing collaboration strategies with interdisciplinary networks in research is a crucial success factor for the companies in any sector, especially in manufacturing for aeronautics. In the aeronautical supply chain, Small and Medium sized Enterprises (SMEs) lack of these types of alliances with universities and other research institutions, which could give them access to shared and specialized knowledge, may strictly limit those companies to learning from their own experience. One way to break this dynamic for industrial companies is to be an active part of research, development, and innovation centres. In this paper, a study to create new advanced manufacturing centres is presented, centres whose activities are focused on Technology Readiness Levels (TRL) 5 7. The approach is based on a project management methodology, and it is applied to the aeronautical sector in the Basque Country. An initial study of the international experience and state of the art in this type of facility, as well as an analysis of the current socioeconomic environment of the Basque Country are presented. A benchmark study was done to identify the key processes that this centre must promote for this initiative to succeed, or those areas of knowledge that can make or break the initiative. Finally, the results showed a definitive picture for establishing an advanced manufacturing centre in the Basque Country. This work lays both the foundations of knowledge in the sector and the difficulties noted, so it can serve as guidance for similar initiatives.
A STOCHASTIC AND CONTINUOUS MODEL OF AEOLIAN VIBRATIONS OF CONDUCTORS EQUIPPED WITH STOCKBRIDGE DAMPERS
Year: 2020

Suspended conductors and guard wires of overhead electrical transmission lines (OHL) are prone to aeolian vibrations, resulting from the alternate shedding of vortices in the wake of the cable. These vibrations can occur under light to moderate wind and, whenever not properly controlled, can induce wear damage and fatigue failures of the cables. Nonlinear passive control devices such as Stockbridge dampers, hence, are often installed along the line spans to reduce the vibration severity. The technical approach to the assessment of aeolian vibrations is based on the Energy Balance Method (EBM) and relies on the simplifying assumption of mono modal oscillations. Typical aeolian vibration records, however, clearly show that several modes can be simultaneously excited due to wind variations in time and along the span. Aiming at overcoming the mono modal vibration assumption of the EBM, in the present paper wind forces are modeled as a narrow band stochastic process, centered around the Strouhal frequency of the conductor and with arbitrary cross correlation in space. A new approach, based on the well known smooth endochronic Bouc Wen model, is developed to describe the hysteretic dynamic response of Stockbridge dampers. An iterative solution strategy based on a stochastically equivalent linear damper model is then developed to investigate aeolian vibrations of a suspended cable with a Stockbridge damper attached along its length.
Quantum model for psychological measurements: from the projection postulate to interference of mental observables represented as positive operator valued measures
Year: 2014

Recently foundational issues of applicability of the formalism of quantum mechanics (QM) to cognitive psychology, decision making, and psychophysics attracted a lot of interest. In particular, in \cite{DKBB} the possibility to use of the projection postulate and representation of "mental observables" by Hermitian operators was discussed in very detail. The main conclusion of the recent discussions on the foundations of "quantum( like) cognitive psychology" is that one has to be careful in determination of conditions of applicability of the projection postulate as a mathematical tool for description of measurements of observables represented by Hermitian operators. To represent some statistical experimental data (both physical and mental) in the quantum( like) way, one has to use generalized quantum observables given by positive operator valued measures (POVMs) This paper contains a brief review on POVMs which can be useful for newcomers to the field of quantum( like) studies. Especially interesting for cognitive psychology is a variant of the formula of total probability (FTP) with the interference term derived for incompatible observables given by POVMs. We present an interpretation of the interference term from the psychological viewpoint. As was shown before, the appearance of such a term (perturbing classical FTP) plays the important role in cognitive psychology, e.g. recognition of ambiguous figures and the disjunction effect. The interference term for observables given by POVMs has much more complicated structure than the corresponding term for observables given by Hermitian operators. We elaborate cognitive interpretations of different components of the POVMs interference term and apply our analysis to a quantum( like) model of decision making.
Cybersecurity Education and Training Support System: CyRIS
Venue: IEICE Trans. Inf. Syst.
Year: 2018

Given the worldwide proliferation of cyberattacks, it is imperative that cybersecurity education and training are addressed in a timely manner. These activities typically require trainees to do hands on practice in order to consolidate and improve their skills, for which purpose training environments called cyber ranges are used. In this paper we present an open source system named CyRIS (Cyber Range Instantiation System) that supports this endeavor by fully automating the training environment setup, thus making it possible for any organization to conduct more numerous and variate training activities. CyRIS uses a text based representation in YAML format to describe the characteristics of the training environment, including both environment setup and security content generation. Based on this description, CyRIS automatically creates the corresponding cyber range instances on a computer and network infrastructure, for simultaneous use by multiple trainees. We have evaluated CyRIS in various realistic scenarios, and our results demonstrate its suitability for cybersecurity education and training, both in terms of features and performance, including for large scale training sessions with hundreds of participants. key words: cybersecurity training, cyber range, education support system
Romantic Breakup: Difficult Loss for Some but Not for Others
Year: 2018

A 32 item survey (completed by 286 undergraduates) identified factors associated with positive (feeling happy, less anxious, sense of relief, freedom) and negative (sadness, jealousy, loss of self esteem, anxiety) outcomes following a romantic breakup or loss. Analysis revealed complex associations but, in general, being female, Black, initiator of the breakup, and heterosexual were more likely to be associated with experiencing positive outcomes. Multivariate analyses suggested that being the initiator of the breakup was a key predictor of more favorable breakup outcomes. Symbolic interaction theory provided the theoretical framework for interpreting the findings, and limitations of the study were identified.
Potential Mechanism for HIV Associated Depression: Upregulation of Serotonin Transporters in SIV Infected Macaques Detected by 11C DASB PET
Venue: Front. Psychiatry
Year: 2019

Increased incidence of depression in HIV+ patients is associated with lower adherence to treatment and increased morbidity/mortality. One possible underlying pathophysiology is serotonergic dysfunction. In this study, we used an animal model of HIV, the SIV infected macaque, to longitudinally image serotonin transporter (SERT) expression before and after inoculation, using 11C DASB (SERT ligand) PET imaging.  We infected seven rhesus macaques with a neurovirulent SIV strain and imaged them at baseline and multiple time points after inoculation (group A) Pyrosequencing methylation analysis of the SERT promoter region was performed. We also measured SERT mRNA/protein in brain single cell suspensions from another group (group B) of SIV infected animals (n 13)  Despite some animals showing early fluctuations, 86% of our group A animals eventually showed a net increase in midbrain/thalamus binding potential (BPND) over the course of their disease (mean increased binding between last time point and baseline 30.2% and 32.2% respectively) Repeated measures mixed model analysis showed infection duration to be predictive of midbrain BPND (p 0.039) Thalamic BPND was statistically significantly associated with multiple CSF cytokines (P 0.05) There was higher SERT protein levels in the second group (group B) of SIV infected animals with SIV encephalitis (SIVE) compared to those without SIVE (p 0.014) There were no longitudinal changes in SERT gene promoter region percentage methylation between baselines and last time points in group A animals.  Upregulated SERT leading to lower synaptic levels of serotonin is a possible mechanism of depression in HIV+ patients, and extrapolating our conclusions from SIV to HIV should be sought using translational human studies.
On the continuing relevance of E. R. Leach's political systems of Highland Burma to Kachin studies
Year: 2007

Sir Edmund Leach's study of Kachin social structure appeared as Political Systems of Highland Burma in 1954, and proceeded to have substantial influence over the study of human society and culture. There are indications that it may well have been one of the most widely read works among published anthropological literature during the second half of the twentieth century. This chapter provides an overview of the reaction, spanning the last fifty years. It begins with the observation that by 1960, Kachin concerns had gelled into a coherent set of issues to address, and that out of that consensus grew a research agenda that has been maintained, to the extent possible, since then. The second observation that is made early in the chapter is that it is written from the perspective of a person who has been part of the Leach Kachin story since 1954.  E. R.

Keeping Models Consistent between Pretraining and Translation for Low Resource Neural Machine Translation
Venue: Future Internet
Year: 2020

Recently, the pretraining of models has been successfully applied to unsupervised and semi supervised neural machine translation. A cross lingual language model uses a pretrained masked language model to initialize the encoder and decoder of the translation model, which greatly improves the translation quality. However, because of a mismatch in the number of layers, the pretrained model can only initialize part of the decoder's parameters. In this paper, we use a layer wise coordination transformer and a consistent pretraining translation transformer instead of a vanilla transformer as the translation model. The former has only an encoder, and the latter has an encoder and a decoder, but the encoder and decoder have exactly the same parameters. Both models can guarantee that all parameters in the translation model can be initialized by the pretrained model. Experiments on the Chinese English and English German datasets show that compared with the vanilla transformer baseline, our models achieve better performance with fewer parameters when the parallel corpus is small.
Spectrum Sensing in a VSAT Network Using Cognitive Radio Technology
Venue: 2019 1st International Conference on Innovations in Information and Communication Technology (ICIICT)
Year: 2019

Satellite Spectrum is a very scarce and costly natural resource. The rapid development in satellite communications has increased the number of users, which in turn, created a demand for more spectral resources. Also due to the ever increasing demand for bandwidth resulted from high data rate requirements, one of the main challenges for satellite communication is to continuously improve the utilization efficiency of the limited exclusive satellite spectrum (Ku band) However, the available spectrum is also not utilized efficiently, which leads to spectrum under utilization. Cognitive Radio (CR) technology has proved to be a promising option to address the spectrum scarcity. In CR, when a primary user (PU) is not utilizing the spectrum, the secondary users (SUs) are allowed to access the spectrum. This paper discusses the Spectrum Sensing in a Very Small Aperture Terminal (VSAT) network by using CR technology which is a new approach in this area. Also, this work will serve as a forerunner for future developments in this domain. VSATs are terminals that communicate with one another through satellite. Applying CR technology in VSATs, spectrum sensing can be performed to detect the spectrum holes where SUs can be accommodated. The spectrum holes are identified in the spectral domain using Fast Fourier Transform (FFT) The simulation results show the retrieved indices of spectrum holes, where SUs are to be accommodated.
Maximum likelihood adaptation of histogram equalization with constraint for robust speech recognition
Venue: 2011 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)
Year: 2011

In this paper, we propose a novel feature space adaptation technique to improve the robustness of speech recognition in noisy environments. Histogram equalization (HEQ) is an effective technique for improving robustness by reducing the difference between clean and noisy features. A weakness of HEQ is that it does not take into account acoustic model, resulting in possible mismatch between HEQ processed features and the acoustic model. In this paper, we propose to adapt HEQ to maximize the likelihood of HEQ processed features on the acoustic model, with a constraint on the parameters of HEQ. In addition, we use a Gaussian mixture model (GMM) to represent the clean feature space rather than using the acoustic model itself, and this results in both simpler implementation and better results. Experimental results show that HEQ with adaptation reduces word error rate by 7.5% and 5.7% respectively on Aurora 2 and Aurora 4 tasks over the HEQ baseline without adaptation.
China's role in the next phase of the energy transition: Contributions to global niche formation in the Concentrated Solar Power sector
Year: 2020

The role that emerging economies, and China in particular, play in the global energy transition appears to be transforming. Transition literature to date characterizes the formation of cleantech sectors in emerging economies as being heavily dependent on foreign inputs of knowledge and other key resources. This article argues that in the, currently unfolding, next phase of the global energy transition, Chinese actors may play a more central role in global niche development for high tech industries, including in constructing innovative and effective socio technical configurations. This argument is illustrated with a case study of the Chinese Concentrated Solar Power industry, which is found to have developed largely independently of foreign resources. The case is used to highlight a number of specificities of the Chinese environment that set it apart from niche formation environments in OECD countries, and may allow China to open up technological trajectories unlikely to develop in those OECD countries.
Debt Restructuring of SMEs Suggested Approaches for Assessment of Credit Needs
Year: 2019

Micro, Small and Medium Enterprises (MSMEs) are known for job creation in the country. But at the grass root level, they continue to experience inadequate credit supply which is a critical input for growth in production and sales. Consequently, the level of non performing assets in MSME sector is high and increasing. One of the ways to assist financially ailing Small and Medium Enterprises (SMEs) is Debt Restructuring to make a project financially viable in the near future. Reserve bank of India introduced Debt Restructuring scheme for SMEs in 2005. Since this scheme is in existence for more than a decade. it calls for a review to suggest improvement it. While RBI has been making changes in debt restructuring guideless from time to time and banks have also been strengthening institutional arrangements, much needs to be done to improve the quality of assessment of credit sanctions as part of debt restructuring exercise. Appreciating this felt need, the article suggests certain new approaches.
