A real time simulation and modeling of flood hazard
Venue: ICONS 2008
Year: 2008

The increasing flash flood hazards in major cities like Kuala Lumpur have caused tremendous damages to the society and this requires more essential countermeasures to be implemented. With the advancement in 3D Computer Graphics and fluid simulation technologies, movie experts can now produce realistic visual effects for fluid objects such as water. This paper describes a study made to model and simulate the flash flood incident that struck Kuala Lumpur on 10 June 2007 using 3D Computer Graphics and fluid simulation techniques. The main goal was to study and examine the stability and effectiveness of this approach as a solution tool for environmental studies. Particle based technique called Smoothed Particle Hydrodynamics (SPH) method were used to model the flash flood behavior. This was done using MAYA plug in software called GLU3D which was developed based on SPH architecture. Geographical Information System (GIS) data such as Light Detection and Ranging (LIDAR) Digital Elevation Model (DEM) and remote sensing imagery were used to model the study area. Results show an adequate realism of water movement for the area studied. A prototype of a flood system was developed using MAYA Application Programming Interface (API) to examine the real time effectiveness of flood movement. The study has verified the usability of 3D computer graphics and fluid simulation particle based technique for environmental study purposes. The main contribution the study was to show that this approach can produce a realistic visualization thus enable more precautions and countermeasures to prevent the disaster.
AN EMPIRICAL STUDY ON RESELLING OF COUNTERFEITS: MARKET ORIENTATIONS
Year: 2014

2The emergence of 'economical spare parts' available at affordable prices has resulted in abundance of counterfeit products in the markets. As the extent of counterfeiting is increasing in almost every industry, it is becoming critical to develop measures that can help in preventing selling and buying of counterfeit products. In exploring resellers selling and consumers' buying behavior of counterfeit products, this study is designed to examine the influence of market orientation and consumer orientation, that generate the supply and demand for counterfeit brands. This study employeds five theoretical frameworks: (a) Market Orientation Scale, (b) The Theory of Planned behavior, (c) Value Attitude Behavioral intention system, (d) Bandwagon effect in the theory of consumer demand, and (e) Aberrant consumer behavior. Specifically, this study investigates industrial resellers and consumers' intentions to purchase counterfeit brands based on their market orientation (customer orientation, competitor orientation and inter functional coordination) and personal consumer orientation (ethical value, social responsibility, legal and price quality schema) and subjective norm towards the reselling and purchase of counterfeit brands. Further, this study aims to explore the role of price sensitivity as a moderator in understanding intentions to resell and purchase counterfeit and original B2B spare parts.

Why is the choice of the language of instruction in which students learn best seldom made? A closer look at results from LOITASA project in Tanzania
Year: 2009

The objective of this project is to examine how children in African societies can be taught in ways that provide the highest quality learning environment. The study will examine why mother tongue education is not used in schools in Africa when study after study shows that this creates the best learning environment. Language is the tool which makes learning possible. Why is the choice of the language of instruction in which learner could learn best seldom made in Tanzania? Further, the study will examine how language and other aspects of quality learning are treated across the public/private educational divide. Education through schooling is a right; however, many poor and marginalized children in Africa do not have access to school. In what ways does the trend towards private schooling in Africa affect the rights of poor and marginalized children to schooling and quality learning? Why are dropout rates high in public school and is this related to poor pedagogical support? The project will examine the ways in which financial support and pedagogical support in public and private schools affect learning in Africa. I will set my fieldwork in Tanzania and focus on one private and one public school to see how and why private schooling is growing and how and why they use English in private schools and Kiswahili in public schools? What are the advantages and disadvantages of these choices and what are the consequences for poor children? Another focus of the study will be on the private schooling issue. The increase in private schooling disfavors the poor and limits their educational choices. What is the trend in education in Tanzania towards private education and how are poor children fairing?

Examining the Impact of Leader Member Exchange on Perceptions of Organizational Justice: The Mediating Role of Perceptions of Organizational Politics
Year: 2018

The present study examines the mediating role of perceptions of organizational politics on the relationship between leader member exchange and perceptions of organizational justice. With the help of multi stage random sampling technique, data was collected from 493 faculty members who were working in public sector universities of Punjab. Structural Equation Modeling (SEM) was applied to test the proposed hypothesized relationships. Results of the structural equation modeling analysis demonstrated that employees who are part of in group have higher levels of perceptions of organizational politics but lower levels of perceptions of organizational justice. Furthermore, employee who perceives high degree of organizational politics has shown lower levels of perceptions of organizational justice. Results of the study postulated that for more positive perceptions of organizational justice among the employees a leader should develop a high quality relationship with more employees by limiting the usage of more political behavior within the organization. This study is one of its type in Indian context as we find no empirical evidence which examines the effect of quality of leader member exchange relationship on the perceptions of organizational justice which is being mediated through the perceptions of organizational politics of faculty members.
High Frequency Trading During Flash Crashes: Walk of Fame or Hall of Shame?
Year: 2020

We show that High Frequency Traders (HFTs) are not beneficial to the stock market during flash crashes. They actually consume liquidity when it is most needed, even when they are rewarded by the exchange to provide immediacy. The behavior of HFTs exacerbate the transient price impact, unrelated to fundamentals, typically observed during a flash crash. Slow traders provide liquidity instead of HFTs, taking advantage of the discounted price. We thus uncover a trade o. between the greater liquidity and efficiency provided by HFTs in normal times, and the disruptive consequences of their trading activity during distressed times.
Surveying the endomicrobiome and ectomicrobiome of bark beetles: The case of Dendroctonus simplex
Venue: Scientific reports
Year: 2015

Many bark beetles belonging to the Dendroctonus genus carry bacterial and fungal microbiota, forming a symbiotic complex that helps the insect to colonize the subcortical environment of the host tree. However, the biodiversity of those bacteria at the surface of the cuticle or inside the body parts of bark beetles is not well established. The aim of this study was to characterize the bacterial microbiome associated with the eastern larch beetle, Dendroctonus simplex, using bacterial 16S rRNA gene pyrosequencing. The ecto and endomicrobiome and the subcortical galleries were investigated. Several bacterial genera were identified, among which Pseudomonas, Serratia and Yersinia are associated with the surface of the beetle cuticle, and genera belonging to Enterobacteriaceae and Gammaproteobacteria with the interior of the insect body. The index of dissimilarity indicates that the bacterial microbiome associated with each environment constitutes exclusive groups. These results suggest the presence of distinct bacterial microbiota on the surface of the cuticle and the interior of D. simplex body. Additionally, the bacterial diversity identified in the galleries is substantially different from the ectomicrobiome, which could indicate a selection by the insect. This study reports for the first time the identification of the eastern larch beetle microbiome.
Early detection of heart failure with varying prediction windows by structured and unstructured data in electronic health records
Venue: 2015 37th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC)
Year: 2015

Heart failure (HF) prevalence is increasing and is among the most costly diseases to society. Early detection of HF would provide the means to test lifestyle and pharmacologic interventions that may slow disease progression and improve patient outcomes. This study used structured and unstructured data from electronic health records (EHR) to predict onset of HF with a particular focus on how prediction accuracy varied in relation to time before diagnosis. EHR data were extracted from a single health care system and used to identify incident HF among primary care patients who received care between 2001 and 2010. A total of 1,684 incident HF cases were identified and 13,525 controls were selected from the same primary care practices. Models were compared by varying the beginning of the prediction window from 60 to 720 days before HF diagnosis. As the prediction window decreased, the performance [AUC (95% CIs) of the predictive HF models increased from 65% (63% 66% to 74% (73% 75% for the unstructured, from 73% (72% 75% to 81% (80% 83% for the structured, and from 76% (74% 77% to 83% (77% 85% for the combined data.
Implementation of Blockchain Data Obfuscation
Year: 2019

Data protection is no longer a luxury. With so much of sensitive, personal, financial transaction events which involves money or online payment for buying or selling of goods, data gets transmitted online. Hence, security and privacy have become the need of everyone who participates in those events. Blockchain is our use case for securing the data from any major data breaches and keeping data safe enough. Thus, blockchain data obfuscation or data masking refers to the process in which essential data is masked and stored in the form of the blocks, where each block is connected to preceding blocks in the form of a chain. The blockchain application allows greater transparency, as the blockchain is a type of distributed book and it also provides enhanced security and traceability of data, for example, when the items\goods are recorded on a blockchain, we can backtrack items to their point of origin. Once the data is recorded on the blockchain then a customer can trust the accuracy of blockchain data, as the data cannot be manipulated. The advantage of blockchain is that it will reduce the cost of business, by removing middlemen or third parties.
Shrub encroachment can reverse desertification in semi arid Mediterranean grasslands.
Venue: Ecology letters
Year: 2009

The worldwide phenomenon of shrub encroachment in grass dominated dryland ecosystems is commonly associated with desertification. Studies of the purported desertification effects associated with shrub encroachment are often restricted to relatively few study areas, and document a narrow range of possible impacts upon biota and ecosystem processes. We conducted a study in degraded Mediterranean grasslands dominated by Stipa tenacissima to simultaneously evaluate the effects of shrub encroachment on the structure and composition of multiple biotic community components, and on various indicators of ecosystem function. Shrub encroachment enhanced vascular plant richness, biomass of fungi, actinomycetes and other bacteria, and was linked with greater soil fertility and N mineralization rates. While shrub encroachment may be a widespread phenomenon in drylands, an interpretation that this is an expression of desertification is not universal. Our results suggest that shrub establishment may be an important step in the reversal of desertification processes in the Mediterranean region.
Immigration, acculturation and the paradox of adaptation in Europe
Year: 2008

Drawing from the International Comparative Study of Ethnocultural Youth (ICSEY) dataset, this paper examines the immigrant paradox phenomenon among a group of immigrant youth in five European countries. The sample consisted of over 2700 immigrant and 1400 national youth (age range 13 18 years) living in Finland, the Netherlands, Norway, Portugal and Sweden. At the core of the immigrant paradox is the counterintuitive finding that immigrants often show better adaptation outcomes than their national peers in spite of poorer socioeconomic status. However, the paper argues for a more conservative position based on three criteria for concluding the existence of the paradox. On the bases of these criteria, the paper found mixed support for the immigrant paradox. Whereas the pattern of socio cultural adaptation for first and second generation immigrants resembled the immigrant paradox, results for psychological adaptation were opposite to the paradox. Reasons for the mixed findings are discussed.
Scale to scale energy and enstrophy transport in two dimensional Rayleigh Taylor turbulence
Venue: Journal of Fluid Mechanics
Year: 2015

We apply a recently developed filtering approach, i.e. filter space technique (FST) to study the scale to scale transport of kinetic energy, thermal energy, and enstrophy in two dimensional (2D) Rayleigh Taylor (RT) turbulence. Although the scaling laws of the energy cascades in 2D RT systems follow the Bolgiano Obukhov (BO59) scenario due to buoyancy forces, the kinetic energy is still found to be, on average, dynamically transferred to large scales by an inverse cascade, while both the mean thermal energy and the mean enstrophy move towards small scales by forward cascades. In particular, there is a reasonably extended range over which the transfer rate of thermal energy is scale independent and equals the corresponding thermal dissipation rate at different times. This range functions similarly to the inertial range for the kinetic energy in the homogeneous and isotropic turbulence. Our results further show that at small scales the fluctuations of the three instantaneous local fluxes are highly asymmetrically distributed and there is a strong correlation between any two fluxes. These small scale features are signatures of the mixing and dissipation of fluids with steep temperature gradients at the fluid interfaces.

Year: 2020

Pandemic COVID 19 is a new epidemic that is sweeping the world with a high level of fatal potential. The role of communication is vital as a response to global health disasters. Thus, the communication network and information dissemination process about COVID 19 need to be expanded as a disaster mitigation effort. The question is how information dissemination can be done, whereas, on the other hand, a person is prohibited from crowding and having physical meetings. Based on this question, this research was conducted to obtain a crisis communication model and what strategies are used in communicating it. This study aims to find a COVID 19 impact crisis communication model using the local wisdom of Gending Jawa in Ngandong Village. Gending Jawa is Javanese traditional music, also known as Karawitan This study used a qualitative descriptive method with a simulation with the leaders and members of the Jati Art Studio, community leaders/religious leaders, and village officials. The results of this study are in the form of the discovery of a COVID 19 impact crisis communication model using the local wisdom of Gending Jawa The contribution of this research is the COVID 19 crisis communication, model whose results can be used or applied to other communities.
Legal capacity, mental capacity and supported decision making: Report from a panel event
Venue: International journal of law and psychiatry
Year: 2019

Against a backdrop of the UN Convention on the Rights of Persons with Disabilities having been in place for over a decade, discussions about legal capacity, the relevance of mental capacity and the shift to supported decision making, continue to develop. A panel event was held at the King's Transnational Law Summit in 2018 with the aim of understanding the contours of the dialogue around these issues. This paper presents the contributions of the panel members, a summary of the discussion that took place and a synthesis of the views expressed. It suggests that divergent conclusions in this area turn on disagreements about: the consequences of sometimes limiting legal capacity for people with mental disabilities; the emphasis placed on particular values; the basis for mental capacity assessments; and the scope for supported decision making. It also highlights the connection between resources, recognition and freedoms for people with mental disabilities, and therefore the issues that arise when discussion in this area is limited to legal capacity in the context of decision making.
Modeling of a System for Organization of Traffic via a Terminal Network
Year: 2019

The research subject is a terminal network. The research purpose is development of a set theoretical model of the terminal network. The research methods are based on the theory of sets, the theory of transport systems, the general system theory, and the authors' methodology of terminalistics. The research provides a parametric description of the terminal network and its key elements: logistical facilities; identifies factors that determine the composition and configuration of the terminal network; develops a model of the terminal network as a logistical chain and, on its basis, suggests an integrated set theoretical model of a region's terminal network. A model for forming the composition of the terminal network is provided. The terminal network is considered as a logistical chain, since its configuration, purpose in a delivery system, and logistical functions performed in transportation sections reproduce the morphology of a classical logistical chain connecting a cargo sending customer with a cargo receiving customer while providing a transparent, integrated, and seamless service for cargo traffic. Using a complex of enlarged block modules of the terminal network, element by element study and optimization become possible. The task of finding the best option of the terminal network becomes a three level and two step task. The research results can be used as an economic and mathematical toolbox in design, development planning, and evaluation of facilities of the terminal and warehouse infrastructure of RZD OJSC.
DYNAMICALLY DRIVEN EVOLUTION OF THE INTERSTELLAR MEDIUM IN M51
Year: 2009

Massive star formation occurs in giant molecular clouds (GMCs) an understanding of the evolution of GMCs is a prerequisite to develop theories of star formation and galaxy evolution. We report the highest fidelity observations of the grand design spiral galaxy M51 in carbon monoxide (CO) emission, revealing the evolution of GMCs vis a vis the large scale galactic structure and dynamics. The most massive GMCs (giant molecular associations (GMAs) are first assembled and then broken up as the gas flow through the spiral arms. The GMAs and their H_2 molecules are not fully dissociated into atomic gas as predicted in stellar feedback scenarios, but are fragmented into smaller GMCs upon leaving the spiral arms. The remnants of GMAs are detected as the chains of GMCs that emerge from the spiral arms into interarm regions. The kinematic shear within the spiral arms is sufficient to unbind the GMAs against self gravity. We conclude that the evolution of GMCs is driven by large scale galactic dynamics their coagulation into GMAs is due to spiral arm streaming motions upon entering the arms, followed by fragmentation due to shear as they leave the arms on the downstream side. In M51, the majority of the gas remains molecular from arm entry through the interarm region and into the next spiral arm passage.
BERT IAN Model for Aspect based Sentiment Analysis
Venue: 2020 International Conference on Communications, Information System and Computer Engineering (CISCE)
Year: 2020

Aspect based sentiment analysis is different from document level and sentence level sentiment analysis, which aims to predict the sentiment polarity of a certain aspect in a sentence. The accuracy of the existing aspect based sentiment analysis model still needs to be improved. A BERT IAN sentiment analysis model that improves the Interactive Attention Networks (IAN) model is proposed to further improve the accuracy of the aspect based sentiment analysis. First use the BERT pre training model to encode aspects and context respectively. Then use a transformer encoder with interactive attention to interactively learn the attention of the aspect and context, and generate a final representation. Finally, through the sentiment classification layer, the aspect corresponding sentiment are analyzed. The experimental results on Restaurant and Laptop datasets show the effectiveness and superiority of the BERT IAN model.
