Comparison of the Madden Julian Oscillation Related Tropical Cyclone Genesis over the South China Sea and Western North Pacific under Different El Nino Southern Oscillation Conditions
Year: 2020

This paper explores the Madden Julian Oscillation (MJO) modulation of tropical cyclone (TC; hereafter, MJO TC) genesis over the South China Sea (SCS) and Western North Pacific (WNP) under different El Nino Southern Oscillation (ENSO) conditions. Analyses used Joint Typhoon Warning Center (JTWC) best track data, the Real Time Multivariate MJO (RMM) index, and European Center for Medium Range Weather Forecasts (ECMWF) Interim (ERA Interim) reanalysis data. The results showed that the MJO has significant modulation on both the SCS and WNP TC genesis in neutral years, with more (fewer) TCs forming during the active (inactive) MJO phases. However, during the El Nino and La Nina years, the MJO TC genesis modulation over the two regions differs from each other. Over the SCS, the MJO modulation of TC genesis is stronger in the La Nina years, while it becomes weaker in the El Nino years. Over the WNP, the MJO has a stronger influence on TC genesis in the El Nino years compared to that in the La Nina years. Related Genesis Potential Index (GPI) analysis suggests that midlevel moisture is the primary factor and vorticity is the secondary factor, for the MJO TC genesis modulation over the SCS in the La Nina years. Over the WNP, midlevel moisture is the dominant factor for the MJO TC genesis modulation during the El Nino years. These results can be explained by increased water vapor transport from the Bay of Bengal, associated with enhanced westerly wind anomalies, during the active phases relative to the inactive MJO phases; these conditions prevail over the SCS during the La Nina years, and over the WNP during the El Nino years.

Business process reengineering framework and methodology: a critical study
Year: 2018

Business process reengineering (BPR) has become a most popular change management approach for radical redesign and improvement of business process. It promotes companies to do things effectively in order to achieve overall quality. Unfortunately, it has been estimated that more than 70% of BPR implementations have failed to achieve expected results due to lake of suitable framework and methodology. Therefore, the author tried to assess the available some different BPR framework and methodology aiming to develop a suitable framework and methodology as well as to fill the literature gap. The other aims of this study are to study the BPR factors that may influence the performance and to explore the implementation level of BPR in Indian manufacturing organisations. In this paper, a proposed common BPR framework and methodology for organisations has developed based on the design of recent BPR frameworks and methodologies identified in the literature. The major component factors of BPR for the manufacturing organisations have been shown in figure. This paper also presents the success and failure factor that affect BPR projects. Finally, the conclusion places the findings of this study and outlines the expected benefits of BPR.

Trajectory planning of autonomous vehicles
Year: 2018

Autonomous driving is an emerging technology that is advancing in a very fast way. It is a complex challenge that involves many sections with plenty of different disciplines. One of the more important parts is trajectory planning, where this thesis it has been focused. This project revises the different algorithms of trajectory planning that have been proposed for autonomous cars. The reason why a trajectory planner based on numerical optimization algorithm such that Model Predictive Control (MPC) is proposed is also discussed. The main advantages are the possibility of generating the planning online allowing the replanning if unexpected events occurs (objects in the middle of the road, pedestrians appearing unexpectedly, etc. and the facility of including several objectives in the optimization problem. This thesis studies different parameter that can define an optimal generated trajectory and how it is structured in the optimization program. Moreover there are several weights that should be tuned to orientate the trajectory planner in the direction that it is desired. All this tuning process is explained providing guidelines on how can be done for future cases. Finally, several testing results were included that are obtained with different parameters and structures of the program. These results are analysed and some conclusions of the efficiency of the MPC based planning algorithm are obtained highlighting the advantages that it presents.
Effect of roughness and shape factor on flotation characteristics of glass beads
Year: 2016

The effect of surface roughness and shape factor on behavior of particles in flotation has been investigated. Surface roughness of various degrees was applied on spherical glass beads of 150 +106 mm by means of acid etching. The same procedure was also performed on ground glass beads of the same size interval with different shape factors. The effect of these variations on surface morphology of particles was investigated in terms of flotation recovery, contact angle, and bubble particle attachment. An Atomic Force Microscope (AFM) was used for surface roughness characterizations and a correction methodology on roughness measurements of spherical particles is proposed. A digital image analyzer was used for shape factor characterizations. It is shown that increase in surface roughness improves the flotation recovery, contact angle, and bubble attachment. Shape factor, however, was found to be more predominant in flotation and bubble attachment. This is attributed to the effect of sharp edges of ground particles which triggers the film rupture process and shortens the attachment time.
Unveiling "Musica Universalis" of the Cell: A Brief History of Biological 12 Hour Rhythms
Venue: Journal of the Endocrine Society
Year: 2018

Musica universalis" is an ancient philosophical concept claiming the movements of celestial bodies follow mathematical equations and resonate to produce an inaudible harmony of music, and the harmonious sounds that humans make were an approximation of this larger harmony of the universe. Besides music, electromagnetic waves such as light and electric signals also are presented as harmonic resonances. Despite the seemingly universal theme of harmonic resonance in various disciplines, it was not until recently that the same harmonic resonance was discovered also to exist in biological systems. Contrary to traditional belief that a biological system is either at stead state or cycles with a single frequency, it is now appreciated that most biological systems have no homeostatic "set point," but rather oscillate as composite rhythms consisting of superimposed oscillations. These oscillations often cycle at different harmonics of the circadian rhythm, and among these, the ~12 hour oscillation is most prevalent. In this review, we focus on these 12 hour oscillations, with special attention to their evolutionary origin, regulation, and functions in mammals, as well as their relationship to the circadian rhythm. We further discuss the potential roles of the 12 hour clock in regulating hepatic steatosis, aging, and the possibility of 12 hour clock based chronotherapy. Finally, we posit that biological rhythms are also musica universalis: whereas the circadian rhythm is synchronized to the 24 hour light/dark cycle coinciding with the Earth's rotation, the mammalian 12 hour clock may have evolved from the circatidal clock, which is entrained by the 12 hour tidal cues orchestrated by the moon.
A comparativist's predicaments of writing about 'other' education: a self reflective, critical review of studies of Japanese education
Year: 2011

This self reflexive essay teases out the predicaments that I have encountered through my past publishing experience, while situating them in a critical review of the existing English language studies of Japanese education. Drawing on postcolonial theoretical insights and recent critical sociology of academic knowledge production, I use my personal experience as a starting point to identify the particular discursive structure of comparative education that constrains the articulation of 'other' education in the field. My critical review of comparative studies of Japanese education demonstrates that many of them, including my own, unreflexively accept the subject positions offered by this discursive condition and thus further constrain space for those who write in English about 'other' education and Japanese education in particular. In conclusion, I discuss recent studies of Japanese education that partially address the dilemmas raised in this paper and the wider implications of this study for the field of comparative education.
When Bert Forgets How To POS: Amnesic Probing of Linguistic Properties and MLM Predictions
Venue: ArXiv
Year: 2020

A growing body of work makes use of probing in order to investigate the working of neural models, often considered black boxes. Recently, an ongoing debate emerged surrounding the limitations of the probing paradigm. In this work, we point out the inability to infer behavioral conclusions from probing results, and offer an alternative method which is focused on how the information is being used, rather than on what information is encoded. Our method, Amnesic Probing, follows the intuition that the utility of a property for a given task can be assessed by measuring the influence of a causal intervention which removes it from the representation. Equipped with this new analysis tool, we can now ask questions that were not possible before, e.g. is part of speech information important for word prediction? We perform a series of analyses on BERT to answer these types of questions. Our findings demonstrate that conventional probing performance is not correlated to task importance, and we call for increased scrutiny of claims that draw behavioral or causal conclusions from probing results.
LSTM EFG for wind power forecasting based on sequential correlation features
Venue: Future Gener. Comput. Syst.
Year: 2019

Amid the gradual increase of wind power generation, how to relieve the pressure of peak load and frequency regulation to the power system by wind power forecasting to make it run steadily becomes a key issue. Due to the continuous development of the field of artificial intelligence, neural network, as a machine learning technology, has shown a good predictive effect in time series data forecasting. Long term short term Memory is a kind of time recursive neural network, which is suitable for processing and predicting events with relatively Long intervals and delays in time series. This paper proposes an improved Long Short Term Memory enhanced forget gate network model, abbreviated as LSTM EFG, used to forecasting wind power. Based on the correlation, the features data of turbine groups in certain distance are filtered to further optimize the forecasting effect on wind power by clustering. The results show that the method with Spectral Clustering has an higher accuracy with an increase of 18.3% than those of the other forecasting models, and at the same time the convergence process has been sped up.
The Old Nordic Middle Voice in the pre literary period: Questions of grammaticalisation and cliticisation
Year: 2008

In this paper, data from sources predating the earliest preserved manuscripts, runic inscriptions as well as poetry, is used to shed light on the earliest history of the morphologically defined Nordic Middle Voice, ending in sk in Old West Nordic and in s in Old East Nordic. This category has not only the reflexive meaning inherited from the reflexive clitic sk but also i.a. reciprocal and anticausative meaning. The semantic development must be independent from the formal development including cliticisation, as shown by comparison with the German Middle Voice, which lacks cliticisation. The formal development includes generalisation of the clitic sk from the 3rd person and infinitive as well as from the accusative to the dative (and genitive) The cliticisation is not restricted to arguments to the verbal hosts, but can involve elements very loosely connected to the verb. Morphological and syntactic arguments show that the clitic must have become an affix as early as the 9th and 10th centuries.
The potential of cognitive think aloud protocols for educational action research
Year: 2019

This article presents the case for the use of the 'think aloud protocol' by teachers who engage in action research as a source of constructive information about their students' cognitive learning processes. This method calls upon learners to talk their thoughts out aloud, during engagement in some learning activity regarding which the researching teachers seek insight to inform them to plan enhancement of the learning and teaching process. The case for 'think aloud' reporting of particular learning activities is supported by a review of relevant literature. Accounts of diverse experiences in various discipline areas using modified versions of think aloud protocols in action researching are presented, with reports of their transformative outcomes. Reasoned reservations regarding the reliability of uncorroborated sources of retrospective data about students' learning are advanced. Refined methodologies are outlined together with general guidelines, for those minded to explore their value in their own contexts.
Research on Lossless Data Compression Technology
Year: 2018

The implementation of data compression technology can be divided into software compression and embedded hardware compression. The software compression operation is large, requires large data buffer space, and does not have real time performance. This does not meet the requirements of real time transmission of telemetry system; embedded hardware compression overcomes the above shortcomings of software compression and is widely used in telemetry systems. Data compression is divided into lossy compression and lossless compression. The high reliability and data accuracy of the aerospace telemetry system determine that only lossless compression can be used to facilitate the analysis of data by technicians and make correct judgments.
A Comparison of Learning Outcomes in Culinary Education: Recorded Video vs. Live Demonstration
Year: 2013

This study examined learning outcomes for students who were enrolled in an introductory cooking course that used online taped videos. The study sample was composed of 206 students enrolled in online taped video classes and 184 enrolled in traditional live classes. The students in both groups received the same teaching instructions except for the demonstration delivery methods. A 2 way mixed design was used to test for significant differences in student performance between 2 instructional delivery methods (i.e. online taped video and live class demonstration) for both individual and team tasks. The results indicated that both delivery methods produced similar student performance levels when individual and team tasks were considered together. However, students taught by the online delivery method had better group performance than students taught by the traditional method. The findings suggest that the online delivery method should be utilized in culinary arts education; however, efforts to enhance group synergy could enhance group performance in educational environments that use this delivery method.
Separation of methane from ethane and propane by selective adsorption and diffusion in MOF Cu BTC: A molecular simulation study.
Venue: Journal of molecular graphics modelling
Year: 2020

Pure methane is an alternative source of cleaner energy. Although, natural gas contains around 90% of methane, there are other heavier alkanes such as ethane and propane. Presence of these heavier hydrocarbons affects the reusability of an adsorbed natural gas system (ANG) Thus, separation of these higher alkanes from methane is important. In the present study, we employed molecular simulation techniques to assess the performance of MOF Cu BTC for separation of methane from ethane and propane at 298 K and for a range of pressure. The assessment was carried out on the basis of variety of performance metrics suitable for adsorption based separation. The performance metrics that we relied upon are adsorption selectivity, working capacity, regenerability (R% adsorption performance score (APS) diffusion selectivity, and membrane selectivity. We investigated the performance for two equimolar binary mixtures methane/ethane and methane/propane, and two ternary mixtures one equimolar mixture and the other containing 90% methane, 7% ethane, and 3% propane. The adsorption selectivity of ethane over methane and propane over methane are really attractive indicating good performance of the MOF in separating the two binary mixtures. We also investigated the effect of the presence of ethane and propane on the mobility of methane. The diffusivities of methane, although, reduces by some factor in presence of ethane and propane, are sufficiently higher at all the pressures and at different compositions with ethane and propane. Finally, we assessed the performance of Cu BTC as a membrane for separation of methane from ethane and propane.
Forward scanning in verbal working memory updating
Venue: Psychonomic bulletin review
Year: 2015

Effective use of working memory (WM) for high level cognitive tasks requires coordinating two conflicting requirements: robust maintenance and rapid updating. Models of WM suggest that these demands are coordinated by a gate between perceptual input and WM. Previous work with a letter updating paradigm (Kessler Oberauer, Journal of Experimental Psychology: Learning, Memory, and Cognition, 40, 738 754, 2014) supported a scanning and gate switching (SGS) model of WM updating. The present work provides further evidence for the SGS model. Participants were required to keep track of the last letter that appeared in each of a row of frames on the screen. On each updating step, a variable subset of letters in varying positions in the row had to be updated. The SGS model assumes that on each updating step, participants scan through the memory set sequentially, opening the gate when a letter requires updating, and closing the gate when the next letter needs to be maintained. As is predicted by the SGS model, the reaction times for each updating step increased with the number of updated items and with the number of gate switches. In addition, the present experiment provides direct evidence supporting the scanning assumption of the model. Hebrew speaking participants performed the task with either Hebrew or English letter stimuli, in different blocks. As was predicted, the scanning direction of the stimulus set was from left to right in English and from right to left in Hebrew. The SGS model fit the data only when the scanning direction was taken into account, establishing the role of item based forward scanning during WM updating.
Predictive Power of Adaptive Candlestick Patterns in Forex Market. Eurusd Case
Year: 2020

The Efficient Market Hypothesis (EMH) states that all available information is immediately reflected in the price of any asset or financial instrument, so that it is impossible to predict its future values, making it follow a pure stochastic process. Among all financial markets, FOREX is usually addressed as one of the most efficient. This paper tests the efficiency of the EURUSD pair taking only into consideration the price itself. A novel categorical classification, based on adaptive criteria, of all possible single candlestick patterns is presented. The predictive power of candlestick patterns is evaluated from a statistical inference approach, where the mean of the average returns of the strategies in out of sample historical data is taken as sample statistic. No net positive average returns are found in any case after taking into account transaction costs. More complex candlestick patterns are considered feeding supervised learning systems with the information of past bars. No edge is found even in the case of considering the information of up to 24 preceding candlesticks.
