Electric Vehicles Driven by 5 Phase Open End Winding Machines Fed by Battery and Supercapacitors
Venue: 2019 IEEE Vehicle Power and Propulsion Conference (VPPC)
Year: 2019

This paper presents the modeling and control of an Electric Vehicle (EV) driven by a 5 phase Permanent Magnet Synchronous Machine (PMSM) The machine in an open end winding configuration is supplied by two isolated 5 leg Voltage Source Inverters (VSIs) The inverters are fed by a Hybrid Energy Storage System (HESS) consisting of a battery and Supercapacitors (SCs) To increase the battery lifetime, the SCs are used to provide the high power requirement during driving operations. In addition, an Energy Management Strategy (EMS) is proposed to take advantages of this EV architecture. Numerical results are derived to verify workability of the EV system.
Looking beneath the surface: how brands led to consumer engagement in social media
Year: 2016

It is undeniable that the strong growth of social media and content generated in them is presented as a rising tide that came to stay! We are facing a change of structural nature, requiring brands to understand that shift and to adapt their strategies as they start looking at consumers as active partners, developing with them a close relationship, collaborative, deeply relational, reinforcing and strengthening the bond and an emotional connection. This fact led to an explosion of interest in consumer engagement. The opportunities presented by social media to help build close relationships with consumers seem to have attracted the increasing interest of practitioners in a wide variety of industries worldwide. Academic scholarship consumer engagement, however, has lagged practice and its theoretical foundation is relatively underdeveloped and a better understanding of the concept and their drivers is essential to develop accurate strategies. This paper seeks to address some of these issues. From the universe of brands, two popular fashion brands (Cubanas and Paez) were selected, based on RankUPT[1] a statistics website aimed at the analysis of Facebook's activity in Portugal that makes a daily measurement of homepages, based on the number of fans. A qualitative netnographic study was conducted, through a non interventionist observational technique, added with a collection of qualitative behavioral data which took place between March and December 2015, and also considering the use of secondary data for the descriptive analysis of the brands in question. Metrics used for measuring engagement were the most commonly used in other studies (e.g. likes, sharing, commenting) along with the de Vries, Gensler and Leeflang  Cvijiki and Michaheles  and Malhotra, Malhotra and See  criteria for the drivers of engagement. The results are discussed and the academic and business implications of the study are examined, in particular for branding and relationship marketing.
Empirical Bayes Estimation in Exponential Model Based on Record Values under Asymmetric Loss
Year: 2011

In this paper, the empirical estimates is derived for the parameter of the exponential model based on record values by taking quasi prior and inverse prior Gamma distributions using the LINEX loss and entropy loss functions. These estimates are compared with the corresponding maximum likelihood (ML) and Bayes estimates, and also compared with the corresponding Bayes estimates under squared error loss function. A Monte Carlo simulation is used to investigate the accuracy of estimation.
Real time planning for automated multi view drone cinematography
Venue: ACM Trans. Graph.
Year: 2017

We propose a method for automated aerial videography in dynamic and cluttered environments. An online receding horizon optimization formulation facilitates the planning process for novices and experts alike. The algorithm takes high level plans as input, which we dub virtual rails, alongside interactively defined aesthetic framing objectives and jointly solves for 3D quadcopter motion plans and associated velocities. The method generates control inputs subject to constraints of a non linear quadrotor model and dynamic constraints imposed by actors moving in an a priori unknown way. The output plans are physically feasible, for the horizon length, and we apply the resulting control inputs directly at each time step, without requiring a separate trajectory tracking algorithm. The online nature of the method enables incorporation of feedback into the planning and control loop, makes the algorithm robust to disturbances. Furthermore, we extend the method to include coordination between multiple drones to enable dynamic multi view shots, typical for action sequences and live TV coverage. The algorithm runs in real time on standard hardware and computes motion plans for several drones in the order of milliseconds. Finally, we evaluate the approach qualitatively with a number of challenging shots, involving multiple drones and actors and qualitatively characterize the computational performance experimentally.

Plasticity in the developing brain: implications for rehabilitation.
Venue: Developmental disabilities research reviews
Year: 2009

Neuronal plasticity allows the central nervous system to learn skills and remember information, to reorganize neuronal networks in response to environmental stimulation, and to recover from brain and spinal cord injuries. Neuronal plasticity is enhanced in the developing brain and it is usually adaptive and beneficial but can also be maladaptive and responsible for neurological disorders in some situations. Basic mechanisms that are involved in plasticity include neurogenesis, programmed cell death, and activity dependent synaptic plasticity. Repetitive stimulation of synapses can cause long term potentiation or long term depression of neurotransmission. These changes are associated with physical changes in dendritic spines and neuronal circuits. Overproduction of synapses during postnatal development in children contributes to enhanced plasticity by providing an excess of synapses that are pruned during early adolescence. Clinical examples of adaptive neuronal plasticity include reorganization of cortical maps of the fingers in response to practice playing a stringed instrument and constraint induced movement therapy to improve hemiparesis caused by stroke or cerebral palsy. These forms of plasticity are associated with structural and functional changes in the brain that can be detected with magnetic resonance imaging, positron emission tomography, or transcranial magnetic stimulation (TMS) TMS and other forms of brain stimulation are also being used experimentally to enhance brain plasticity and recovery of function. Plasticity is also influenced by genetic factors such as mutations in brain derived neuronal growth factor. Understanding brain plasticity provides a basis for developing better therapies to improve outcome from acquired brain injuries.
A Hybrid MCDM Technique for Risk Management in Construction Projects
Venue: Symmetry
Year: 2018

Multi stakeholder based construction projects are subject to potential risk factors due to dynamic business environment and stakeholders' lack of knowledge. When solving project management tasks, it is necessary to quantify the main risk indicators of the projects. Managing these requires suitable risk mitigation strategies to evaluate and analyse their severity. The existence of information asymmetry also causes difficulties with achieving Pareto efficiency. Hence, to ensure balanced satisfaction of all participants, risk evaluation of these projects can be considered as an important part of the multi criteria decision making (MCDM) process. In real life problems, evaluation of project risks is often uncertain and even incomplete, and the prevailing methodologies fail to handle such situations. To address the problem, this paper extends the analytical network process (ANP) methodology in the D numbers domain to handle three types of ambiguous information's, viz. complete, uncertain, and incomplete, and assesses the weight of risk criteria. The D numbers based approach overcomes the deficiencies of the exclusiveness hypothesis and completeness constraint of Dempster Shafer (D S) theory. Here, preference ratings of the decision matrix for each decision maker are determined using a D numbers extended consistent fuzzy preference relation (D CFPR) An extended multi attributive border approximation area comparison (MABAC) method in D numbers is then developed to rank and select the best alternative risk response strategy. Finally, an illustrative example from construction sector is presented to check the feasibility of the proposed approach. For checking the reliability of alternative ranking, a comparative analysis is performed with different MCDM approaches in D numbers domain. Based on different criteria weights, a sensitivity analysis of obtained ranking of the hybrid D ANP MABAC model is performed to verify the robustness of the proposed method.

Penguins, Hype, and MMOGs for Kids: A Critical Reexamination of the 2008 "Boom" in Children's Virtual Worlds Development
Year: 2018

According to various media and academic sources, the virtual worlds landscape underwent a profound transformation in 2008, with the arrival of numerous new titles designed and targeted specifically to young children. Although a growing body of research has explored some of the titles involved in this shift, little remains known of its overall scope and contents. This article provides a mapping of the initial "boom" in children's virtual worlds development and identifies a number of significant patterns within the ensuing children's virtual worlds landscape. The argument is made that while the reported boom in children's virtual worlds has been exaggerated, a number of important shifts for online gaming culture did unfold during this period, some of which challenge accepted definitions of "virtual world" and "multiplayer online game." The implications of these findings are discussed in light of contemporary developments and trends within children's digital culture and within online gaming more broadly.
Efficient Concurrent Execution of Smart Contracts in Blockchains Using Object Based Transactional Memory
Venue: NETYS
Year: 2020

Popular blockchain such as Ethereum and several others execute complex transactions in blocks through user defined scripts known as smart contracts. Normally, a block of the chain consists of multiple transactions of smart contracts which are added by a miner. To append a correct block into blockchain, miners execute these smart contract transactions (SCT) sequentially. Later the validators serially re execute the SCT of the block. In the current era of multi core processors, by employing serial execution of the transactions, the miners and validators fail to utilize the cores properly and as a result have poor throughput. By adding concurrency using object semantics to smart contracts execution, we can achieve the better efficiency and higher throughput. Some authors have used read write STMs (RWSTMs) for the concurrent execution of SCT. Working with higher level operations provide greater concurrency, better throughput and reduces the number of aborts than RWSTMs. In this paper, we develop an efficient framework to execute the SCT concurrently by miner using optimistic Object Based Software Transactional Memory systems (OSTMs) and Multi Version OSTMs (MV OSTM) A proposed block includes SCT, final states of the shared data items, hash of the previous block and a block graph (BG) BG captures the conflicting relations among the transactions. Later, the validators re execute the same SCT concurrently and deterministically with the help of BG given by miner to verify the final state. If the validation is successful then proposed block appended into the blockchain and miner gets incentive otherwise discard the proposed block. MV OSTM and OSTM miner performs 4.5x and 3.86x average speedups over serial miner. Along with, MV OSTM and OSTM validator outperforms average 32.81x and 29.76x than serial validator.
Reading, Reasoning, and Literacy: Strategies for Early Childhood Education From the Analysis of Classroom Observations
Year: 2012

Researchers have posited that children generally learn to read in environments that are trusting, comfortable, and offer small group or one to one adult support, all of which are characteristics of a high quality early childhood education program. This evaluation research study examines the Pre Kindergarten Incentive Program, an early childhood demonstration program in Washington, DC designed to study several urban community based sites. The authors facilitate a discourse on how all early childhood education programs can become high quality programs through standardized observations, evaluations, and constructive feedback. The article describes the demonstration program, highlights general findings from standardized classroom observations, discusses areas needing improvement, and presents strategies for addressing areas of challenge. It will reveal to early childhood educators how evaluation findings can improve teaching and learning techniques and environments in early childhood programs. The goal is to promote overall improvement in reading, reasoning, and literacy for children enrolled in early childhood programs and thereby better prepare them for kindergarten.

A total of 76.43% had positive perception in practicing fish farming while 23.57% had no interest. Awareness about fisheries as profession revealed that 72.14% are aware while 27.86% are unaware. Conclusively, the perception of secondary school students to fisheries is encouraging, so there is prospect for fisheries as a profession in Borno state. It will be recommended that more awareness should be created to secondary school students about fisheries profession and as prospect for youth empowerment.  Fisheries, Perception, School, Student,
Stress communication and filtering of viscoelastic layers in oscillatory shear
Year: 2009

We revisit a classical topic: response functions of viscoelastic layers in large amplitude oscillatory shear. Motivated by questions concerning protective biological layers, we focus on boundary stresses in a parallel plate geometry with imposed oscillatory strain or stress. These features are gleaned from resolution and analysis of coupled standing waves of deformation and stress. We identify a robust non monotone variation in boundary stress signals with respect to all experimental controls: viscoelastic moduli of the layer, layer thickness, and driving frequency. This structure of peaks and valleys in boundary values of shear and normal stress indicates redundant mechanisms for stress communication (by tuning to the peaks) and stress filtering (by tuning to the valleys) In this paper, we first restrict to a single mode non linear Maxwell model for the viscoelastic layer, where analysis renders a transparent explanation of the phenomena. We then consider a Giesekus constitutive model of the layer, where analysis is supplanted by numerical simulations of coupled non linear partial differential equations. Parametric studies of wall stress values from standing waves confirm persistence of the Maxwell model phenomena. The analysis and simulations rely on and extend our recent studies of shear waves in a micro parallel plate rheometer [S.M. Mitran, M.G. Forest, L. Yao, B. Lindley, D. Hill, Extenstions of the Ferry shear wave model for active linear and nonlinear microrheology,  (2008) 120 135; D.B. Hill, B. Lindley, M.G. Forest, S.M. Mitran, R.

Approaches to measuring the risk of cyberattacks in remote banking services of Russia
Year: 2019

Due to the use of technology in banks their risks of information security breach are rising significantly. In the context of active introduction of remote banking systems (RBS) in banking business of Russia, additional study of issues of assessing the risk of cyberattacks on banking automated systems was required.  The methods of financial management, probability theory, system analysis of scientific literature on fundamental and applied research, and a method of graphical interpretation of analyzed phenomena are used. The paper gives a detailed analysis of the concepts of "cyberspace" and "cybersecurity" Remote banking is considered from the point of view of financial management. Attention is drawn to the factors of work in cyberspace that increase the levels of banking risks. The relationship of cyberattacks on banking automated systems and possible consequences for the bank is analyzed. Novelty. Given the wide spread of social engineering methods when committing fraudulent activities on the Internet the measures to increase the cyber literacy of population are needed. The method for assessing the risk of cyberattacks on RBS for use by risk department specialists and employees of internal control services is developed. As a result, considering innovative systems and technologies that await us in the future, the effectiveness of risk assessment for solving current challenges is increased.  Attempts are made to formulate the mathematical model of the probabilistic analysis of information security incidents to optimize the algorithm for responding to incidents. Calculations based on the proposed model made it possible to determine the duration of exploitation of vulnerability of RBS, when the probability of preventing an incident exceeds probability of its realization. The findings may be useful for scientific research on the risks of information security breach in RBS.

Lean and complex systems: a case study of materials handling at an on land warehouse facility supporting subsea gas operations
Year: 2018

Commonly warehouse management is subject to deterministic planning procedures within the organizational scope of supply chain management. Lately lean principles have become more widespread and also adapted to develop materials handling within warehouses. Several facets of analysis are considered in this case study on outsourced warehousing in the Norwegian petroleum industry. This study reveals empirically how outsourced warehousing as service provision involves an organization problem with waste found both at the service management and at the process levels. Analysis points to how lean principles of process improvement may be combined with complex systems thinking. The case reveals examples of how warehouse management and its operations are full of complexities leading to waste. While lean usually is used hands on to manage these wastes through manual incremental development, another organisation of continuous innovation is suggested here. Lean is suggested be developed as organizational context of complex systems information warehouse management system software. Following lean principles evokes many types of process waste at the studied warehouse. Instead on following the manual stepwise and continuous process improvement approach of lean in all areas of organization, a more radical change to complex systems evident in information system design to support warehousing processes is proposed with lean as its organizational context.
