Regulatory Control of Amine Scrubbing for CO2 Capture from Power Plants

Tight integration between the amine scrubbing plant, coal fired power plant, and enhanced oil recovery (EOR) facility creates process design and control challenges for post combustion CO2 capture. A dynamic model of an advanced amine scrubbing process and a steady state model of a 550 MWe power plant were used to examine four bounding cases that represent different system components dominating the regulatory process control strategy. Satisfying the operational and economic objectives of one system component resulted in unfavorable dynamic performance for the remainder of the system. When a step change decrease occurred in either the CO2 delivery rate from the capture plant to the EOR facility or the steam extraction rate from the power plant to the capture plant, more than 3 h was required for the amine plant to reach a new steady state. Attempting to control the CO2 removal rate from the flue gas can not be satisfactorily achieved through regulatory control alone. Controlling stripper temperature and pre.
Assessment of Oral Status in Pediatric Patients with Special Health Care Needs receiving Dental Rehabilitation Procedures under General Anesthesia: A Retrospective Analysis.
Venue: The journal of contemporary dental practice

Dental problems serve as additional burden on the children with special health care needs (CSHCN) because of additional hospitalization pressure, they face for the treatment of various serious medical problems. These patients have higher incidence of dental caries due to increased quantity of sugar involved in the drug therapies and lower salivary flow in the oral cavity. Such patients are difficult to treat with local anesthesia or inhaled sedatives. Single sitting dental treatment is possible in these patients with general anesthesia. Therefore, we conducted this retrospective analysis of oral health status of CSHCN receiving various dental treatments in a given population.  A total of 200 CSHCN of age 14 years or less reporting in the pediatric wing of the general hospital from 2005 to 2014 that underwent comprehensive dental treatment under general anesthesia were included in the study. Patients with history of any additional systemic illness, any malignancy, any known drug allergy, or previous history of any dental treatment were excluded from the study. Complete mouth rehabilitation was done in these patients under general anesthesia following standard protocols. Data regarding the patient's disability, type, duration, and severity of disability was collected and analyzed. All the results were analyzed by Statistical Package for the Social Sciences (SPSS) software. Chi square test, Student's t test, and one way analysis of variance were used to assess the level of significance.  Statistically significant results were obtained while analyzing the subject's decayed missing filled/decayed extracted filled teeth indices divided based on age. Significant difference was observed only in cases where patients underwent complete crown placement even when divided based on type of disability. While analyzing the prevalence, statistically significant results were observed in patients when divided based on their age.  In CSHCN, dental pathologies and caries indices are increased regardless of the type or extent of disability.  Children with special health care needs should be given special oral health care, and regular dental checkup should be conducted as they are more prone to have dental problems.

Ribosome mediated synthesis of natural product like peptides via cell free translation.
Venue: Current opinion in chemical biology

Peptide natural products (PNPs) represent a unique class of compounds known for their fascinating structural motifs with important biological activities. Lately, PNPs have garnered a lot of interest for their application in drug discovery. Nevertheless, lack of diversity oriented synthetic/biosynthetic platforms to generate large natural product like libraries has limited their development as peptide therapeutics. The promiscuity of cell free translation has allowed for the synthesis of artificial PNPs having complex structural features. Modified cell free translation systems coupled with the display technologies have generated diverse natural product like peptide libraries and led to the discovery of several biologically active molecules. Such technologies have drastically decreased the time to obtain peptide drug leads and therefore, revolutionized the field of peptide drug discovery. In this account, we review recent developments in the synthesis of natural product like peptides via cell free translation.
An analysis on operational risk in international banking: A Bayesian approach (2007 2011)

This study aims to develop a Bayesian methodology to identify, quantify and measure operational risk in several business lines of commercial banking. To do this, a Bayesian network (BN) model is designed with prior and subsequent distributions to estimate the frequency and severity. Regarding the subsequent distributions, an inference procedure for the maximum expected loss, for a period of 20 days, is carried out by using the Monte Carlo simulation method. The business lines analyzed are marketing and sales, retail banking and private banking, which all together accounted for 88.5% of the losses in 2011. Data was obtained for the period 2007 2011 from the Riskdata Operational Exchange Association (ORX) and external data was provided from qualified experts to complete the missing records or to improve its poor quality.
Suppression law of quantum states in a 3D photonic fast Fourier transform chip
Venue: Nature communications

The identification of phenomena able to pinpoint quantum interference is attracting large interest. Indeed, a generalization of the Hong Ou Mandel effect valid for any number of photons and optical modes would represent an important leap ahead both from a fundamental perspective and for practical applications, such as certification of photonic quantum devices, whose computational speedup is expected to depend critically on multi particle interference. Quantum distinctive features have been predicted for many particles injected into multimode interferometers implementing the Fourier transform over the optical modes. Here we develop a scalable approach for the implementation of the fast Fourier transform algorithm using three dimensional photonic integrated interferometers, fabricated via femtosecond laser writing technique. We observe the suppression law for a large number of output states with four and eight mode optical circuits: the experimental results demonstrate genuine quantum interference between the injected photons, thus offering a powerful tool for diagnostic of photonic platforms.
Capturing complex behaviour for predicting distant future trajectories
Venue: MobiGIS

We put forth a system, to predict distant future positions of multiple moving entities and index the forecasted trajectories, in order to answer predictive queries involving long time horizons. Today, the proliferation of mobile devices with GPS functionality and internet connectivity has led to a rapid development of location based services, accounting for user mobility prediction as a key paradigm. Mobility prediction is already playing a major role in traffic management, urban planning and location based advertising, which demand accurate and long time horizon forecasting of user movements. Existing prediction methodologies either use motion patterns or techniques based on frequently visited places for predicting the next move. However, when it comes to distant future, human mobility is too complex to be represented by such statistical functions. Therefore, the existing techniques are not well suited to answer distant future queries with a satisfactory level of accuracy. To tackle this problem, we introduce a novel spatial object, 'Representative Trajectory' which embodies the movements of users amongst their zones of interest. We propose means to empirically evaluate the quality of this object and dynamically adapt its extraction method based on user mobility behaviour. We rely on an inverted index to store the predicted trajectories that scales well with the number of moving entities. Our evaluation results show that the technique achieves more than 70% accurate predictions with the best extraction technique. This shows that longer query time horizons do not necessarily demand complex spatial indexing schemes, which have to be rebalanced as they grow and which is a constantly experienced problem while answering predictive queries.
Comparison of FLAASH and QUAC atmospheric correction methods for Resourcesat 2 LISS IV data
Venue: SPIE Asia Pacific Remote Sensing

The LISS IV sensor aboard Resourcesat 2 is a modern relatively high resolution multispectral sensor having immense potential for generation of good quality land use land cover maps. It generates data in high (10 bit) radiometric resolution and 5.8 m spatial resolution and has three bands in the visible near infrared region. This is of particular importance to global community as the data are provided at highly competitive prices. However, no literature describing the atmospheric correction of Resourcesat 2 LISS IV data could be found. Further, without atmospheric correction full radiometric potential of any remote sensing data remains underutilized. The FLAASH and QUAC module of ENVI software are highly used by researchers for atmospheric correction of popular remote sensing data such as Landsat, SPOT, IKONOS, LISS I, III etc. This article outlines a methodology for atmospheric correction of Resourcesat 2 LISS IV data. Also, a comparison of reflectance from different atmospheric correction modules (FLAASH and QUAC) with TOA and standard data has been made to determine the best suitable method for reflectance estimation for this sensor.
Multimodal Spontaneous Emotion Corpus for Human Behavior Analysis
Venue: 2016 IEEE Conference on Computer Vision and Pattern Recognition (CVPR)

Emotion is expressed in multiple modalities, yet most research has considered at most one or two. This stems in part from the lack of large, diverse, well annotated, multimodal databases with which to develop and test algorithms. We present a well annotated, multimodal, multidimensional spontaneous emotion corpus of 140 participants. Emotion inductions were highly varied. Data were acquired from a variety of sensors of the face that included high resolution 3D dynamic imaging, high resolution 2D video, and thermal (infrared) sensing, and contact physiological sensors that included electrical conductivity of the skin, respiration, blood pressure, and heart rate. Facial expression was annotated for both the occurrence and intensity of facial action units from 2D video by experts in the Facial Action Coding System (FACS) The corpus further includes derived features from 3D, 2D, and IR (infrared) sensors and baseline results for facial expression and action unit detection. The entire corpus will be made available to the research community.
Multi modal emotion analysis from facial expressions and electroencephalogram
Venue: Comput. Vis. Image Underst.

Emotion recognition from spontaneous facial expression with a new percentage feature.Extraction and selection of spectral power and spectral power difference features for EEG.A multi modal emotion recognition for valence and arousal classes.A comparison of multi modal emotion recognition to human performance for emotion recognition and analysis. Display Omitted Automatic analysis of human spontaneous behavior has attracted increasing attention in recent years from researchers in computer vision. This paper proposes an approach for multi modal video induced emotion recognition, based on facial expression and electroencephalogram (EEG) technologies. Spontaneous facial expression is utilized as an external channel. A new feature, formed by percentage of nine facial expressions, is proposed for analyzing the valence and arousal classes. Furthermore, EEG is used as an internal channel supplementing facial expressions for more reliable emotion recognition. Discriminative spectral power and spectral power difference features are exploited for EEG analysis. Finally, these two channels are fused on feature level and decision level for multi modal emotion recognition. Experiments are conducted on MAHNOB HCI database, including 522 spontaneous facial expression videos and EEG signals from 27 participants. Moreover, human perception in emotion recognition compared to the proposed approach is tested with 10 volunteers. The experimental results and comparisons with the average human performance show the effectiveness of the proposed multi modal approach.
Removal of heavy metal ions using chitosan and modified chitosan: A review

Chitosan and its modifications have received great attention over the past few decades due to its outstanding adsorption behavior toward various toxic heavy metals from aqueous solutions. In the review, the preparation strategies of modified chitosan (MCS) and its applications have been summarized. The effects of process variables (such as pH, temperature, adsorbent dosage, contact time, and co existing ions) adsorption kinetics and isotherms, and adsorption mechanism were investigated. Moreover, the process parameters of heavy metal ions onto MCSs were optimized by response surface methodology. Finally, the regeneration of MCSs has been given considerable attention to evaluate their adsorption efficiency, and some dynamic adsorption studies were also discussed. The main objective of this review is to provide up to date information about the most important features of chitosan based adsorbents that may be helpful for synthesizing better adsorption property of modified chitosan and promoting its applications for heavy metal contaminate removal.
Acoustic backscattering and radiation force on a rigid elliptical cylinder in plane progressive waves.
Venue: Ultrasonics

This work proposes a formal analytical theory using the partial wave series expansion (PWSE) method in cylindrical coordinates, to calculate the acoustic backscattering form function as well as the radiation force per length on an infinitely long elliptical (non circular) cylinder in plane progressive waves. The major (or minor) semi axis of the ellipse coincides with the direction of the incident waves. The scattering coefficients for the rigid elliptical cylinder are determined by imposing the Neumann boundary condition for an immovable surface and solving a resulting system of linear equations by matrix inversion. The present method, which utilizes standard cylindrical (Bessel and Hankel) wave functions, presents an advantage over the solution for the scattering that is ordinarily expressed in a basis of elliptical Mathieu functions (which are generally non orthogonal) Furthermore, an integral equation showing the direct connection of the radiation force function with the square of the scattering form function in the far field from the scatterer (applicable for plane waves only) is noted and discussed. An important application of this integral equation is the adequate evaluation of the radiation force function from a bistatic measurement (i.e. in the polar plane) of the far field scattering from any 2D object of arbitrary shape. Numerical predictions are evaluated for the acoustic backscattering form function and the radiation force function, which is the radiation force per unit length, per characteristic energy density, and per unit cross sectional surface of the ellipse, with particular emphasis on the aspect ratio a/b, where a and b are the semi axes, as well as the dimensionless size parameter kb, without the restriction to a particular range of frequencies. The results are particularly relevant in acoustic levitation, acousto fluidics and particle dynamics applications.
Effect of imperfect interface on the dynamic response of a circular lined tunnel impacted by plane P waves

A theoretical method for studying the dynamic response of a circular lined tunnel with an imperfectly bonded interface subjected to plane P waves is presented in the paper. The wave function expansion method was used and the imperfect interface was modeled with a spring model. Two cases were discussed in the paper. In the first case rock is harder than the lining and vice versa in the second case. The results indicated that the variation in the stiffness of the interface has much influence on the distribution of dynamic stress concentration factors (DSCF) in the rock and the lining. The imperfection of the interface has a more noticeable influence on the DSCF in the rock mass and the lining at high frequency incident wave's scenario than low frequency incident wave's scenario. The resonance scattering phenomena can be observed when the bond is extremely weak. Limiting cases were considered and a good agreement with the solutions available in the literature was obtained.
M3: A Hardware/Operating System Co Design to Tame Heterogeneous Manycores
Venue: ASPLOS 2016

In the last decade, the number of available cores increased and heterogeneity grew. In this work, we ask the question whether the design of the current operating systems (OSes) is still appropriate if these trends continue and lead to abundantly available but heterogeneous cores, or whether it forces a fundamental rethinking of how systems are designed. We argue that: 1. hiding heterogeneity behind a common hardware interface unifies, to a large extent, the control and coordination of cores and accelerators in the OS, 2. isolating at the network on chip rather than with processor features (like privileged mode, memory management unit, allows running untrusted code on arbitrary cores, and 3. providing OS services via protocols over the network on chip, instead of via system calls, makes them accessible to arbitrary types of cores as well. In summary, this turns accelerators into first class citizens and enables a single and convenient programming environment for all cores without the need to trust any application. In this paper, we introduce network on chip level isolation, present the design of our microkernel based OS, M3, and the common hardware interface, and evaluate the performance of our prototype in comparison to Linux. A bit surprising, without using accelerators, M3 outperforms Linux in some application level benchmarks by more than a factor of five.

Exploring the Micro politics in Transitions from a Practice Perspective: The Case of Greenhouse Innovation in the Netherlands

This article takes up the challenge of moving beyond a dichotomous reading of 'niches' and 'regimes' in transition literature in order to grasp the power struggles involved in fundamental societal transformations. It is argued that the 'practice turn' in the social sciences, and particularly Knorr Cetina's perspective on objects of knowledge, offer a promising starting point for doing so. To understand the micro politics of transitions, an analytic framework is developed that combines a focus on power with a focus on the creativity at work in the reconfiguration of novel practices. It is used to analyse innovations in the domain of Dutch greenhouse farming and research in the 1990s and 2000s. In contrast with the definition of niches as purposeful constructions, it concludes that innovative practices are gradually and experimentally created out of discontent with, and in relation to, existing practices and that power dynamics involved in the process are tied up with three forms of creativity: (1) the articulation of innovative networks and concepts, (2) the consolidation of the resulting transformation of existing practices, and (3) the innovation of actual material objects. The second form of creativity is employed notably by 'regime actors'
