Static and seismic experiment for bolted welded joint in modularized prefabricated steel structure
Year: 2015

This study proposes a type of bolted welded beam column joint for modularized prefabricated multi rise and high rise steel structures. The components in the same module are welded in the factory, and the modules are quickly assembled using the proposed joint at site. The static performance, hysteretic performance, skeleton curves, ductile performance, energy dissipation capacity, rotation capacity and stiffness degradation patterns of four joints are obtained by model experiment and finite element analyses, and the effect of thicknesses of the chords and web members on the static and seismic performance of the joint as well as the effect of welding quality are investigated. The results show that due to the presence of the bolted connecting parts, the proposed joints maintain relatively good seismic performance including ductile performance, energy dissipation capacity and plastic rotation capacity, and good static bearing capacity after the welding seams fracture, so they can be used in structures of seismic zones. Reducing the thicknesses of the chord and the web members can significantly decrease the load bearing capacity of the joint; however, this decrease is not proportional to the decrease of the cross sectional area. In addition, reducing the thicknesses of the chord and web members has no significant impact on the ductile performance and energy dissipation capacity of the joint. Simplified computation formulas for load bearing capacity of the joint were proposed and the computation results get along well with the experimental results.
Non standard monetary policy measures in the new normal
Year: 2019

We evaluate the macroeconomic effects of long term sovereign bond purchases by the central bank in the 'New Normal' i.e. in an economy with a low equilibrium real interest rate and a high probability of hitting the zero lower bound (ZLB) on the short term policy rate. Our analysis is based on the simulations of a dynamic general equilibrium model for the euro area. The main results are the following. First, long term sovereign bond purchases reacting to a positive inflation gap help stabilize macroeconomic conditions when the monetary policy rate hits the ZLB. Second, these purchases are an effective stabilization tool following positive shocks to the sovereign term premium (financial shocks) and negative shocks to aggregate demand (real shocks) Third, purchases that also react to the long term rates are effective in the case of recessionary financial shocks but not in the case of recessionary real shocks and fourth, to stabilize the effects of expansionary shocks, the central bank can increase the short term monetary policy rate according to an 'aggressive' Taylor rule, instead of selling long term sovereign bonds.

Feature Extraction Techniques for Facial Expression Recognition Systems
Year: 2016

Automatic facial expression recognition has become a progressive research area since it plays a major role in human computer interaction. The facial expression recognition finds its major application in areas like social interaction and social intelligence. However it is not an easy task because the facial image, facial occlusion, face color/shape etc. is not easy to deal with. In this paper, various techniques for feature extraction like Gabor filters, Principal Component Analysis (PCA) Local Binary Patterns (LBP) Linear Discriminant Analysis (LDA) DCT, with different classifiers like Support Vector Machine (SVM) and Neural Networks, which are used to recognize human expression in various conditions on different databases are being examined. KeywordsFacial expression, Geometric features, Appearance features, PCA, LBP, Gabor, LDA
Spectral clustering for non reversible Markov chains
Year: 2018

Spectral clustering methods are based on solving eigenvalue problems for the identification of clusters, e.g. the identification of metastable subsets of a Markov chain. Usually, real valued eigenvectors are mandatory for this type of algorithms. The Perron Cluster Analysis (PCCA+ is a well known spectral clustering method of Markov chains. It is applicable for reversible Markov chains, because reversibility implies a real valued spectrum. We also extend this spectral clustering method to non reversible Markov chains and give some illustrative examples. The main idea is to replace the eigenvalue problem by a real valued Schur decomposition. By this extension non reversible Markov chains can be analyzed. Furthermore, the chains do not need to have a positive stationary distribution. In addition to metastabilities, dominant cycles and sinks can also be identified. This novel method is called GenPCCA (i.e. generalized PCCA) since it includes the case of non reversible processes. We also apply the method to real world eye tracking data.
Keynote 2: Perceptual and structural analysis of pronunciation diversity of World Englishes
Venue: O COCOSDA
Year: 2014

English is the only language available for global communication but its form is altered easily and variously depending on the mother tongue of speakers and their environment of learning English. It is true that internationalization of things always alters them due to local cultures. English pronunciation is not exceptional and, if we take two users of English, their pronunciation will show different characteristics, called accents. Today, we often hear the term of World Englishes (WE) where it is claimed that there is no standard English and that American English (AE) and British English (BE) are just two major examples of accented English. While everybody agrees that English is a very useful tool, he/she will also agree that, in international contexts, accents can often cause miscommunications. In this talk, the presenter will show the results obtained in two on going projects related to the diversity of pronunciation of WE.

Tailored Near infrared Colloidal Heterostructured Quantum Dots for High Performance Photoelectrochemical Cells
Year: 2019

Colloidal heterostructured CuGaS2 (CGS)/CdS core/shell quantum dots (QDs) with a wurtzite (WZ) phase were synthesized via a facile two step technique. As compared to the bare CGS QDs, the optical properties of such heterostructured CGS/CdS core/shell QDs were tailored to show largely enhanced light absorption in the visible range and an emission peak in the near infrared (NIR) region at a wavelength of ~816 nm. As proof of concept, these core/shell QDs were used as light absorbers to fabricate a photoelectrochemical (PEC) cell, which exhibited a maximum saturated photocurrent density of ~6.5 mA cm 2 and outstanding stability under standard one sun illumination (AM 1.5G, 100 mW cm 2) The results indicate that these NIR core/shell QDs are promising candidates for future QD based optoelectronic technologies such as QD sensitized solar cells (QDSCs)

Year: 2017

Electrodynamic properties of Pb(Fe0.95Sc0.05)2/3W1/3O3 solid solution belonging to A(B'B')O3 perovskite structural family have been investigated by broadband dielectric spectroscopy in a wave number range of (4 x 10 9 4 x 103) cm 1 and a temperature range of 100 600 K. The influence of low frequency relaxations on the vibrational spectrum is determined within the four parameter factorized dispersion model. Anomalies in the behavior of the dielectric response function are found near the temperature diffuse maximum of permittivity.
The Indispensable Roles of the School Librarian in a School: A Brief Review
Year: 2017

One cannot discuss school libraries without touching the role of school librarians. For a library to be effective there need to be a professional librarian. The aim of the paper was to identify the roles played by school librarians in the school vicinity. The paper highlighted that the teacher librarian or school librarian should be well qualified as a teacher and a librarian so as to be able to play his/her role in teaching, and providing the library services. The researcher made some recommendations based on literature that every school library should be staffed by a professional school librarian who will be able to effectively perform his/her librarian duties maximally. School librarians should also be trained as a teacher as well as be trained as a librarian so that they are competent in their duties.

Experimental investigation on the effect of using crumb rubber and steel fibers on the structural behavior of reinforced concrete beams
Year: 2020

The effect of combination between crumb rubber and steel fibers on the behavior of reinforced concrete beams under static loads was investigated in this study. Crumb rubber, ranging in size between 2 mm and 3 mm, was produced from waste tires. Then, it was incorporated into plain concrete (PC) and steel fiber concrete (SFC) mixes by partially replacing of fine aggregates at different percentages by weight (5% 10% 15% and 20% Steel fibers volume fraction was kept constant at 1% An extensive experimental program of 130 samples was conducted in two stages. The first stage included compressive test, splitting tensile test, and flexural test, in order to investigate the mechanical properties of the designed concrete mixtures. The second stage was carried out to investigate the static behavior of reinforced concrete beams, using the designed concrete mixtures, under four points flexural test. Test results showed that using crumb rubber as partial replacement of fine aggregates by 5% and 10% show an acceptable performance of reinforced concrete beams. Using steel fibers with rubberized concrete with percentages of rubber over than 10% improved the performance and the toughness of these mixtures.
Dysregulated Brain Dynamics in a Triple Network Saliency Model of Schizophrenia and Its Relation to Psychosis
Venue: Biological Psychiatry
Year: 2019

Schizophrenia is a highly disabling psychiatric disorder characterized by a range of positive "psychosis" symptoms. However, the neurobiology of psychosis and associated systems level disruptions in the brain remain poorly understood. Here, we test an aberrant saliency model of psychosis, which posits that dysregulated dynamic cross network interactions among the salience network (SN) central executive network, and default mode network contribute to positive symptoms in patients with schizophrenia.  Using task free functional magnetic resonance imaging data from two independent cohorts, we examined 1) dynamic time varying cross network interactions among the SN, central executive network, and default mode network in 130 patients with schizophrenia versus well matched control subjects; 2) accuracy of a saliency model based classifier for distinguishing dynamic brain network interactions in patients versus control subjects; and 3) the relation between SN centered network dynamics and clinical symptoms.  In both cohorts, we found that dynamic SN centered cross network interactions were significantly reduced, less persistent, and more variable in patients with schizophrenia compared with control subjects. Multivariate classification analysis identified dynamic SN centered cross network interaction patterns as factors that distinguish patients from control subjects, with accuracies of 78% and 80% in the two cohorts, respectively. Crucially, in both cohorts, dynamic time varying measures of SN centered cross network interactions were correlated with positive, but not negative, symptoms.  Aberrations in time varying engagement of the SN with the central executive network and default mode network is a clinically relevant neurobiological signature of psychosis in schizophrenia. Our findings provide strong evidence for dysregulated brain dynamics in a triple network saliency model of schizophrenia and inform theoretically motivated systems neuroscience approaches for characterizing aberrant brain dynamics associated with psychosis.
Wavelet based Denoising of Medical Images Using Sub band Adaptive Thresholding through Genetic Algorithm
Year: 2013

Generally medical images have poor contrast along with serious types of noises. The suppression of noise in medical images corrupted by Gaussian white noise is a major issue in diverse image processing and computer vision problems. Image denoising using discrete wavelet transform is well established domain in image processing because it can separate the noisy signal from the image signal. This paper proposed a denoising method of medical images through thresholding and optimization using a stochastic and randomized technique of Genetic Algorithm (GA) The noisy image is partitioned into fixed sized blocks and then transforms it into wavelet domain. Some important parameters in the 2 D discrete wavelet transform such as the decomposition level and the threshold value are searched and optimized in a wide range in the proposed technique. The Bayesian shrinkage method has been selected for thresholding based of its sub band dependency property. Proposed algorithm has been validated through ultrasound image corrupted by a variety of noise densities through Gaussian noise in terms of peak signal to noise ratio and visual effects. Simulation results show that the proposed method outperforms the existing denoising methods.
A Global Review of Incentive Payments for Sea Turtle Conservation
Year: 2009

Performance payment conservation approaches are based on a willing buyer willing seller model. Sellers deliver conservation outcomes in exchange for a negotiated payment in cash or in kind. The use of performance payments to achieve conservation outcomes is increasingly being used as an alternative to traditional regulatory and development based approaches in low income nations. Although payments are increasingly common in terrestrial species and ecosystem conservation initiatives, they are rare in marine conservation efforts such as sea turtle protection. This paper describes sea turtle incentive payment initiatives taking place around the world, most of which are found in projects focusing on nesting beach protection. We find that many of these initiatives have achieved substantial results for a very low annual cost. The potential for expanding payment incentive schemes beyond nest protection to reduce bycatch and hunting pressures on juvenile and adult turtles is unknown but should be further explored.
Extraction of Complex DNN Models: Real Threat or Boogeyman?
Venue: ArXiv
Year: 2019

Recently, machine learning (ML) has introduced advanced solutions to many domains. Since ML models provide business advantage to model owners, protecting intellectual property of ML models has emerged as an important consideration. Confidentiality of ML models can be protected by exposing them to clients only via prediction APIs. However, model extraction attacks can steal the functionality of ML models using the information leaked to clients through the results returned via the API. In this work, we question whether model extraction is a serious threat to complex, real life ML models. We evaluate the current state of the art model extraction attack (Knockoff nets) against complex models. We reproduce and confirm the results in the original paper. But we also show that the performance of this attack can be limited by several factors, including ML model architecture and the granularity of API response. Furthermore, we introduce a defense based on distinguishing queries used for Knockoff nets from benign queries. Despite the limitations of the Knockoff nets, we show that a more realistic adversary can effectively steal complex ML models and evade known defenses.
Uplift and exhumation of the Russell Fiord and Boundary blocks along the northern Fairweather transform fault, Alaska
Year: 2019

Cooling ages of tectonic blocks between the Yakutat microplate and the Fairweather transform boundary fault reveal exhumation due to strike slip faulting and subsequent collision into this tectonic corner. The Yakutat and Boundary faults are splay faults that define tectonic panels with bounding faults that have evidence of both reverse and strike slip motion, and they are parallel to the northern end of the Fairweather fault. Uplift and exhumation simultaneous with strike slip motion have been significant since the late Miocene. The blocks are part of an actively deforming tectonic corner, as indicated by the ~14 1.5 m of coseismic uplift from the M 8.1 Yakutat Bay earthquake of 1899 and 4 m of strike slip motion in the M 7.9 Lituya Bay earthquake in 1958 along the Fairweather fault. New apatite (U Th Sm)/He (AHe) and zircon (U Th)/He (ZHe) data reveal that the Boundary block and the Russell Fiord block have different cooling histories since the Miocene, and thus the Boundary fault that separates them is an important tectonic boundary. Upper Cretaceous to Paleocene flysch of the Russell Fiord block experienced a thermal event at 50 Ma, then a relatively long period of burial until the late Miocene when initial exhumation resulted in ZHe ages between 7 and 3 Ma, and then very rapid exhumation in the last 1 1.5 m.y. Exhumation of the Russell Fiord block was accommodated by reverse faulting along the Yakutat fault and the newly proposed Calahonda fault, which is parallel to the Yakutat fault. The Eocene schist of Nunatak Fiord and 54 53 Ma Mount Stamy and Mount Draper granites in the Boundary block have AHe and ZHe cooling ages that indicate distinct and very rapid cooling between ca. 5 Ma and ca. 2 Ma. Rocks of the Chugach Metamorphic Complex to the northeast of the Fairweather fault and in the fault zone were brought up from 10 12 km at extremely high rates >5 km/m.y. since ca. 3 Ma, which implies a significant component of dip slip motion along the Fairweather fault. The adjacent rocks of the Boundary block were exhumed with similar rates and from similar depths during the early Pliocene, when they may have been located 220 250 km farther south near Baranof Island. The profound and significant exhumation of the three tectonic blocks in the last 5 m.y. has probably been driven by uplift and erosional exhumation due to contraction as rocks collide into this tectonic corner. The documented spatial and temporal pattern of exhumation is in agreement with the southward shift of focused exhumation at the St. Elias syntaxial corner and the southeast propagation of the fold and thrust belt.
