Abstract:
Visual materials that can be used in classes such as PowerPoint presentations, analogies, documentaries and concept cartoons appeal to more than one sense of students and thus enable them to be more active in the learning process and learn more permanently by structuring knowledge in their minds more easily. In concept cartoons used to discover students’ conceptual structures and develop their comprehension, the intention is to create a discussion environment to reach knowledge by discussions without giving the answers directly. With this purpose, primary school candidates were given a variety of pictures and concept cartoons regarding the mole concept in the general chemistry class in order to explore the effect of these images on the concept learning as well as evaluating their view. This study’s result was parallel to the results of the studies that suggest that concept cartoons are effective on improving student success and developing a positive opinion. Keywords: Concept cartoons, chemistry education, mole concept.

Abstract:
In every area of science there are some ideas that many students find difficult to grasp. A lack of understanding of key ideas can limit a student‟s ability to grasp and apply fundamental principles of their discipline. Previous work in this area, by Taber, has focused on this problem at school level. However, little work has been done to systematically investigate and analyse this phenomenon in undergraduate science programmes, beyond the anecdotal. A previous study involving students and staff from a range of scientific disciplines at our university identified that the mole (and its associated applications) was a difficult area for a wide range of students. The mole shows characteristics of being a „Threshold Concept‟ for students. Having identified the mole as a problem, the aim here was to explore why it is difficult and whether the conceptual issues can be systematically overcome, by using multiple perspectives. A sequence of questionnaires was used to survey over 100 people, involving school students aged 14-17, first-, second- and third-year university students, and secondary school teachers, in detail about the mole. We considered respondents‟ learning preferences and the type of activities in science lessons from which they felt they learned the most. Over 50% of respondents reported problems with the mole at some stage of their education. Further insights into how people conceptualise the mole were explored through the use of an educational research technique called „Hot Pen Writing‟. The outcomes of the research identified some of the reasons for student‟s lack of understanding of the mole concept including poor teaching in schools, difficulty in relating the concept to real-life situations and, not surprisingly, the fact that it involves maths. We consider what this suggests about how and when the mole should be taught within school education.

Abstract:
The aim of the research was to use constructivist approach to enhance performance of second year elective science students of Adobewura in mole concept. In order to achieve this, the researcher employed the following research questions; What methods do teachers use to teach mole concept and to what extent can constructivist approach be used to help students understand mole concept. Action research was used since action research is a way of assessing result while operating. Purposive sampling was used to select 30 students for the study. Data were collected through tests (pre-intervention and post-intervention tests). The scores of the pre and post intervention tests were compared and result analyzed. The analyzed results indicated that students’ performance had improved remarkably after the implementation of all the intervention. For instance, when the researcher implemented the demonstration techniques, 23 students scored marks within 41-90 representing 76.67% while 23.33% scored between 41-30. No student scored marks less than 30 marks. Based on the findings of the study, it can be concluded that there are a lot of performance enhancements in using constructivist approach in teaching and learning mole concept at Adobewura SHS since it improves conceptual understanding and also there is a positive effect on students’ attitudes of mole concept. The researcher recommends that the use of constructivist approach in teaching and learning chemistry at the Senior High School should be encouraged by Curriculum developers and education implementers for students should have a hands-on experience with mole concept in learning chemistry.

Abstract:
En 1969, une septieme unite de base est ajoutee au systeme international d'unites de mesure: la mole est l'unite de quantite de matiere. Cette grandeur, introduite sans bruit, n'est pas encore passee dans les habitudes scientifiques. D'ou procede la creation d'une nouvelle grandeur? a quelles exigences repond la definition d'une unite de mesure pour les chimistes? on montre que l'invention de cette notion se situe a la croisee de trois histoires independantes. Elle implique d'abord la notion de poids atomique issue de la chimie du xixe siecle. Ce nombre proportionnel, relatif a une reference conventionnelle, est une carateristique strictement individuelle qui definit l'identite de chaque element. La molecule-gramme ("mole" en abrege), fut introduite dans la chimie physique a la fin du xixe siecle. Elle associe le poids moleculaire a une unite de masse. Elle fonctionne comme une "jauge" chimique et permet d'exprimer des lois generales en nombre de moles. Ainsi pas plus que les chimistes, les physico-chimistes ne definissaient la dimension de la grandeur qu'ils mesuraient. Cependant, grace a la theorie cinetique des gaz, les physiciens referent la molecule-gramme au nombre de molecules contenues dans un volume donne, bref au nombre d'avogadro. La definition de la mole resulte donc avant tout d'une volonte d'harmonisation entre les mesures des physiciens et des chimistes qui s'est concretisee par l'adoption d'une echelle commune de poids atomiques fondee sur l'isotope 12 du carbone. Cette premiere tentative de standardisation ne fut cependant que le prelude a une reflexion metrologique approfondie sur la nature et la dimension de la grandeur mesuree en chimie, menee conjointement par les unions internationales de chimie et de physique. Chimie, physique, metrologie, ces trois disciplines concourent a la definition actuelle de la mole. D'ou la complexite de cette notion de base qui tresse trois logiques distinctes. D'ou l'originalite de son histoire car l'acte fondateurde l'unite de mesure des chimistes ne constitue pas une solution triomphale qui perimerait les concepts anterieurs.

Abstract:
Um fato verificado pelos professores ligados à área de educação química é que o conceito de mol, de fundamental importância para o ensino de química, constitui um obstáculo de aprendizagem, visto que os alunos de ensino médio sentem considerável dificuldade em seu aprendizado, pois o referido conceito requer conhecimentos básicos nem sempre bem definidos na estrutura cognitiva dos estudantes. Para atenuar este problema, foi desenvolvido um software, na forma de jogo didático, baseado nas dificuldades relatadas em entrevistas com professores e alunos e fundamentado na teoria da atividade de Leontiev. O objetivo deste trabalho foi investigar se este recurso auxilia como mediador na aprendizagem do conceito de mol. O jogo é composto de três fases, das quais duas exploram conceitos matemáticos básicos como reconhecimento de fórmulas, cálculos envolvendo potências e relações proporcionais e a terceira fase aborda o conceito de mol propriamente dito. Estudantes do ensino médio utilizaram o software e os dados coletados foram analisados levando-se em conta os testes escritos respondidos pelos alunos e suas ações durante o jogo. Os resultados obtidos, as observações realizadas durante a aplicação do jogo e os comentários dos participantes indicam claramente que o software foi eficaz e motivador, tendo em seu corpo o aspecto lúdico e o educativo, e que contribuiu na aprendizagem do conceito em questão.
A fact verified by teachers involved with Chemistry education is that the concept of mol, extremely important to the teaching of chemistry, makes up an obstacle to the learning process since the referred concept requires some basic knowledge which is not always so well defined in the students\' cognitive structure. In order to attenuate this problem, a software was developed based on the difficulties arisen in the interviews with teachers and students and supported by Leontiev\'s theory of activity. The objective of this paper is to investigate whether this resource could help as a mediator in the learning of mol concept. The game comprises three stages, two of which exploit basic math concepts such as recognizing formulas, calculations involving powers and proportional relations whereas the third one really approaches the concept of mol. Secondary school students made use of the software and the data was collected and analyzed from both the students\' written answers to the tests as well as their actions during the game. The results obtained, the observations made during the game and the comments of the participants clearly point out that the software is effective and motivational, showing also its educative and ludic aspects, which contributed to the learning of the said concept.

Abstract:
Switch mode power supplies are widely used in different applications. High efficiency and high power density are two driving forces for power supply systems. However, high dv/dt and di/dt in switch mode power supplies will cause severe EMI noise issue. In a typical front-end converter, the EMI filter usually occupies 1/3 to 1/4 volume of total converter. Hence, reducing the EMI noise of power converter can help reduce the volume of EMI filter and improving the total power density of the converter. For off-line switch mode power supplies, DM noise is dominated by PFC converter. CM noise is a more complicated issue. It is contributed by both PFC converter and DC/DC converter. While many researches have focused on reducing CM noise for PFC converter, the CM noise of DC/DC converter still remains a challenge. The main objective of this thesis is provide a solution to have best CM noise reduction for DC/DC converters. The shielding concept and balance concept are combined to propose a novel balance double shielding technique. This method can have an effective CM noise reduction in the circuit level. In addition it is easy to design and implement in the real production. The balance condition is easily controlled and guarantees effective CM noise reduction in mass production. Then, a novel one-layer shielding method for PCB winding transformer is provided. This shielding technique can block CM noise from primary side and also cancel the CM noise from secondary side. In addition, shielding does not increase the loss of converter too much. Furthermore, this shielding technique can be applied to matrix transformer structure. For matrix transformer LLC converter, the inter-winding capacitor is very large and will cause severe CM noise problem. By adding shielding layer, CM noise has been greatly reduced. In addition, by modifying the secondary winding, the loss on shielding layer is minimized and experiments show that the total efficiency of converter has almost no impact. Furthermore, although this thesis uses flyback and LLC resonant converter as example to demonstrate the concept, the novel shielding technique can also be applied to other topologies that have similar transformer structure.

Abstract:
Characteristic modes (CMs) provide deep insight into the electromagnetic behaviour of any arbitrarily shaped conducting structure because the CMs are unique to the geometry of the object. We exploit this very fact by predicting a perhaps surprising number of important antenna metrics such as resonance frequency, radiation efficiency and antenna Q (bandwidth) without needing to specify a feeding location. In doing so, it is possible to define a collection of objective functions that can be used in an optimizer to shape-synthesize antennas without needing to define a feed location a priori. We denote this novel form of optimization “feedless” or “excitation-free” antenna shape synthesis. Fundamentally, we are allowing the electromagnetics to dictate how the antenna synthesis should proceed and are in no way imposing the physical constraints enforced by fixed feeding structures. This optimization technique is broadly applied to three major areas of antenna research: electrically small antennas, multi-band antennas and reflectarrays. Thus, the scope of applicability ranges from small antennas, to intermediate sizes and concludes with electrically large antenna designs, which is a testament to the broad applicability of characteristic mode theory. Another advantage of feedless electromagnetic shape synthesis is the ability to synthesize antennas whose desirable properties approach the fundamental limits imposed by electromagnetics. As an additional benefit, the feedless optimization technique is shown to have greater computational efficiency than traditional antenna optimization techniques.

Abstract:
In this thesis we show how characteristic mode (CM) theory can be used to in the design of the antennas with the low envelope correlation coefficients preferred for MIMO antennas. This is due to the fact that the radiated fields of CMs are orthogonal over the radiation sphere. We show how a handheld device structure can be excited at various points (which form the multi-antenna ports) to ensure that each port excites a set of CMs such that the mode indices in each set are different for each antenna. It is this important result which causes the natural orthogonality properties of the CMs to be transferred to the overall radiation patterns of the multiple antennas. The CM analysis we have performed includes the effects of structure losses; it appears to be the first time that the computation of such modes have been reported. A logical and satisfying methodology for MIMO antenna design is the result. The methodology is extended to include arbitrary MIMO scattering environments using polarization sensitive generalized characteristic modes, which is the first of its kind from both the theory and methodology perspective. This design approach for MIMO antennas is not restricted to handheld devices, and can be used in a variety of applications. Lastly we discuss the various port mode theories that yield far-field orthogonality for perfect scattering environments, the application of which has already been discussed in the literature. We show succinctly that physical port symmetry yields frequency insensitive modes, but very minor symmetry breaking yields very narrow low envelope correlation bandwidth, something that is not discussed in the literature, but discussed in detail in this thesis.

Abstract:
Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Nuclear Engineering, 2002.
Includes bibliographical references (leaves 185-188).
In this thesis, a self-consistent model for analyzing the transport performance of a Reversed Field Pinch (RFP)-type of thermonuclear fusion reactor has been developed. The study has been focused on determining equilibrium configurations which describe a plasma evolution dominated by particular instabilities originated by plasma electrical resistivity (tearing-, or resistive interchange, modes). The ultimate goal is to provide a model of transport scaling in an RFP which can evaluate the global parameters describing the plasma confinement performance. Starting from a magnetic field configuration essentially given by Taylor's relaxation model, the self-consistent pressure profile is determined by assuming that the ohmic heating source raises the plasma pressure until the profile is locally marginally stable to tearing modes. A critical point here is the long held belief that an RFP, because of its bad curvature, would always be unstable to tearing or resistive interchange modes; that is, no marginally stable state exists. This belief turns out to be untrue. The basis for this statement is a careful ordering of the resistive layer dynamics, showing that thermal conductivity dominates over convection and compressibility. Thus, the use of the adiabatic equation of state in earlier work is not accurate for an RFP.
(cont.) As a result, tearing and interchange modes can indeed be stabilized in an RFP. In this model, a proper, selfconsistent definition of tearing-mode marginality has been used as a prescription for building the pressure profile. The actual numerical determination of the marginally stable profiles can be solved by using state-of-the-art personal computers. It is worth emphasizing that there are no free parameters in the model. Point checks indicate reasonable agreement with typical experimental data. Parametric numerical studies are also shown, spanning the operational space of RFP experiments, and finally providing the tearing mode transport scaling relations for the global confinement parameters. Comparisons with experiments as well as other transport models are shown.

Abstract:
Data Visualization (DV) can be seen as an important tool for communication and data analysis. Especially when huge amounts of data are involved, visual representation of data can facilitate observation of trends and patterns as well as understanding. Currently, two dimensional displays are mainly used for Data Visualization, both in two and three dimensions (2D and 3D). However, two dimensional displays are limited in terms of 3D visualization because they do not allow for true sense of depth and do not cover the observer’s full Field Of View (FOV). An alternative approach is to use Virtual Reality (VR), which provides an immersive and interactive 3D environment. VR has been mainly used for gaming and simulated training. However, other areas are now emerging because VR technologies became relatively affordable. For example, one possibility is to explore VR for DV and this was the main goal of this project. To accomplish that, a literature study was performed to identify terminologies and definitions, hardware and software technologies, techniques and examples in the fields of DV and VR. In addition, in order to exemplify DV through VR, a prototype system was implemented using Unity 3D, a leading engine for VR. To visualize the developed VR environment, a HTC Vive Head Mounted Display (HMD) was used. The developed prototype system can display data from a local dataset in a scatter plot with three axis in VR. In the virtual environment created by the system, the user can select the attributes in the dataset to be displayed by the 3D scatter plot. Once the data is plotted, the user can use the handheld joystick to move, rotate, tilt and scale the scatter plot. Achieved results indicate immersion and interaction as the main perceived benefits of DV using VR.
Datavisualisering (DV) kan ses som ett viktigt verktyg för kommunikation och dataanalys, speciellt när stora mängder data behandlas. Visuell representation kan främja observationen av trender och mönster samt förståelsen av datan. För närvarande används tvådimensionella displayer huvudsakligen för datavisualisering, både i två och tre dimensioner (2D och 3D). Emellertid är tvådimensionella displayer begränsade i 3D-visualisering eftersom de inte möjliggör äkta djupseende, och täcker inte observatörens fulla synfält (Field Of View (FOV)). Ett alternativ tillvägagångssätt är att använda Virtual Reality (VR), vilket tillhandahåller en omslutande och interaktiv 3D-miljö. VR har huvudsakligen används för spel och simulerad träning. Däremot börjar nya användningsområden uppstå då VR teknologin har blivit mer prisvärd. Ett användningsområde är VR för DV, vilket var det huvudsakliga syftet för det här arbetet. För att uppnå syftet utfördes en litteraturstudie för att identifiera teknologier och definitioner, hårdvaru- och mjukvaruteknologier, tekniker och exempel inom området av DV och VR. Dessutom, för att exemplifiera DV genom VR, utvecklades ett prototypsystem. Vilket implementerades genom  Unity 3D, en av de ledande spelmotorerna. För att visualisera den utvecklade VR-miljön användes ett HTC Vive Head Mounted Display (HMD). Den utvecklade prototypen kan visualisera data från ett lokalt dataset genom ett spridningsdiagram med 3 axlar, i VR. I den virtuella miljön som skapas av systemet tillåts användaren att välja attribut från datasetet för att sedan visualisera dessa genom det tredimensionella spridningsdiagrammet. När datan väl är visualiserad, kan användaren använda de handhållna kontrollerna för att flytta, rotera, luta och skala grafen. Uppnådda resultat indikerar på omslutning och interaktion som de huvudsakliga fördelarna av DV genom VR.

Abstract:
Cette thèse est dédiée à l’étude du multiplexage de mode spatiaux, depuis ses fondements conceptuels jusqu’à ses applications techniques. Le convertisseur optique multi-plan (MPLC ou multiplane light converter) développé par CAILabs est au centre de notre étude. Le travail mené durant cette thèse s’est organisé autour de deux axes de travail. Nous avons d’une part étudié comment la manipulation de modes transverses du champ électromagnétique permet la manipulation ou la mesure de paramètres. Nous démontrons que la limite théorique de sensibilité sur la mesure de petits déplacements d’un faisceau lumineux est atteinte en effectuant une mesure d’intensité sur la base des modes de Hermite-Gauss. Cette démonstration vaut également pour la mesure de distance entre deux sources de lumière incohérentes entre elles. Nous avons confirmé expérimentalement la validité de ce résultat en utilisant un système MPLC adéquat. Un système MPLC peut également être construit afin de transférer le contrôle d’un degré de liberté spatial sur un autre. Nous présentons une expérience dans laquelle nous montrons que l’utilisation d’un tel système permet de contrôler la position du point focal d’un faisceau à l’aide du déplacement ou de l’inclinaison transverse du faisceau d’entrée. D’autre part, nous avons effectué une étude numérique et théorique des propriétés de transport du système MPLC à l’aide d’outils issus de la théorie des matrices aléatoires. Notre but est d’identifier les mécanismes physiques qui rentrent en jeu dans cette technique de mise en forme de la lumière
This thesis is dedicated to spatial mode multiplexing, from its fundamental concepts to its applications. The work is associated with the multi-plane light converter (MPLC) technology developed by CAILabs. This study is divided into two main parts. First, we investigate the use of independent spatial mode shaping to measure or modify spatial parameters of the electromagnetic field. We make the theoretical demonstration that the best sensitivity for the measurement of small displacements of a beam – or of the distance between two incoherent beams – is reached when an intensity measurement is made on the Hermite-Gaussian mode basis. By building the adequate MPLC system, we make the experimental validation of this result. We also make the demonstration that a MPLC system can be designed and used to transfer the control of one spatial parameter of a beam onto another. We built an experimental setup which allows to control the position of the focal point of a beam using transverse displacement and tilt. The second project we conducted was a theoretical and numerical study of the statistical transport properties of the MPLC using tools from random matrix theory. We aim at identifying the underlying physical processes which make up for the efficiency of this transformation technique

Abstract:
A dynamic autothermal methane reformer model has been developed and tested for the production of a hydrogen- and carbon monoxide-rich syngas. This study looks at potential advantages and disadvantages of an autothermal reformer, both operating in stand-alone mode and in conjunction with a high temperature fuel cell stack. The model uses a conservation of moles as the fundamental continuity relationship, and applies basic energy conservation equations to simulate both the gas and the catalyst bed energies. Chemical kinetic expressions using empirical constants for the Arrhenius rate terms that describe steam reformation of methane and partial oxidation of methane are simultaneously solved to provide an accurate picture of the reaction dynamics. This paper presents dynamic responses of reformer outlet temperature, hydrogen mole fraction, reaction rates and methane conversion to the perturbation of the reformer inlet variables of steam-to-carbon ratio, oxygen-to-carbon ratio and inlet gas temperature. Also explored is the concept of catalyst “light-off,” where there is found to be a lower temperature limit above which catalyst activity is substantially increased.

Abstract:
For solid oxide fuel cells (SOFCs) to be commercialized, their strength needs to be improved, as ceramic materials result in reduced strength. Thus, the concept of metal-supported SOFCs has been developed. However, the mass transfer rate in this type of SOFC may be decreased due to the contact layer and the support layer, which can result in low performance. In this paper, the mass transfer characteristics of a metal-supported SOFC were investigated using numerical simulation. The physical property models, the electrochemical reaction models and the governing equations (mass, momentum, energy and species balance) were simulated simultaneously for a multi-physics analysis. Numerical results are compared with experimental data for a code validation. And then, Current density, temperature and mole fraction in single cell were predicted as numerical results.

Full text
Abstract:
One potential method for controlling the combustion phasing of a Homogeneous Charge Compression Ignition (HCCI) engine is to vary the fuel chemistry using two fuels with different auto-ignition characteristics. Although a dual-fuel engine concept is technically feasible with current engine management and fuel delivery system technologies, this is not generally seen as a practical solution due to the necessity of supplying and storing two fuels. Onboard partial reforming of a hydrocarbon fuel is seen to be a more attractive way to realize a dual-fuel concept while relying on only one fuel supply infrastructure. Reformer Gas (RG) is a mixture of light gases dominated by hydrogen and carbon monoxide that can be produced from any hydrocarbon fuel using an onboard fuel processor. RG has a high resistance to auto-ignition and wide flammability limits. The ratio of H2 to CO produced depends on the reforming method and conditions, as well as the hydrocarbon fuel. In this study, a CFR engine was operated in HCCI mode at elevated intake air temperatures and pressures. n-heptane was used as the hydrocarbon blending component because of its high cetane number and well-known fuel chemistry. RG was used as the low cetane blending component to retard the combustion phasing. Other influential parameters such as air/fuel ratio, EGR, and intake temperature were maintained constant. The experimental results show that increasing the RG fraction retards the combustion phasing to a more optimized value causing indicated power and fuel conversion efficiency to increase. RG reduced the first stage of heat release, extended the negative temperature coefficient delay period, and retarded the main stage of combustion. Two extreme cases of RG composition with H2/CO ratios of 3/1 and 1/1 were investigated. The results show that both RG compositions retard the combustion phasing, but that the higher hydrogen fraction RG is more effective. A single-zone model with detailed chemical kinetics was used to interpret the experimental results. The effect of RG on combustion phasing retardation was confirmed. It was found that the low temperature heat release was inhibited by a reduction of intermediate radical mole fractions during low temperature reactions and the early stages of the negative temperature coefficient delay period.

Abstract:
A two-step thermochemical cycle for solar hydrogen production using mixed iron oxides as the metal oxide redox system has been investigated. A reactor concept has been developed in which the metal oxide is fixed on multi-channelled honeycomb ceramic supports capable of adsorbing solar irradiation. In the solar furnace of DLR in Cologne coated honeycomb structures were tested in a solar receiver-reactor with respect to their water splitting capability and their long term stability. The concept of this new reactor design has proven feasible and constant hydrogen production during repeated cycles has been shown. For a further optimization of the process and in order to gain reliable performance predictions more information about the process especially concerning the kinetics of the oxidation and the reduction step are essential. To examine the kinetics of the water splitting and the regeneration step a test rig has been built up on a laboratory scale. In this test rig small coated honeycombs are heated by an electric furnace. The honeycomb is placed inside a tube reactor and can be flushed with water vapour or with an inert gas. A homogeneous temperature within the sample is reached and testing conditions are reproducible. Through analysis of the product gas the hydrogen production is monitored and a reaction rate describing the hydrogen production rate per gram ferrite can be formulated. Using this test set-up, SiC honeycombs coated with a zinc-ferrite have been tested. The influences of the water splitting temperature and the water concentration on the kinetics of the water splitting step have been investigated. A mathematical approach for the reaction rate was formulated and the activation energy was calculated from the experimental data. An activation energy of 110 kJ/mole was found.

Abstract:
In the context of our current planetary crises, in a world that continues to be shaped by capitalist, colonialist, androcentric and anthropocentric visions, we are faced with the urgency of reconsidering, at the deepest levels, the way we relate with other human and nonhuman beings. This working paper aims to contribute towards that end by looking at human-nonhuman relations through the concept of conviviality, understood as the everyday living together with difference, and how it intersects with inequality. In the first part of this paper, more-than-human conviviality-inequality is investigated by critically analyzing onto-epistemological and methodological approaches that question, subvert or reproduce hegemonic thinking and worldviews on humannonhuman relations like historical materialism, new materialisms, transhumanism, posthumanisms, and indigenous relational ontologies. In the second part, I look at particular relational dimensions like incompleteness, translation, and affect, which can help us create new understandings of more-than-human conviviality-inequality in Latin America and beyond.

Abstract:
As environmental uncertainty increases, incorporating resilience into project assessments, research recommendations, and future plans is becoming even more critical. This US Army Engineer Research and Development Center special report (SR) demonstrates how the concepts of resilience can be applied in a uniform framework and illustrates this framework through existing case studies on large inland river systems. This SR presents the concepts of resilience in inland river systems, the application of these concepts across disciplines, basic parameters of a resilience assessment, and the challenges and opportunities available for incorporating a more holistic approach to understanding resilience of the US Army Corps of Engineers mission areas on inland rivers. Finally, these concepts are demonstrated in several case studies in the United States to exemplify how these parameters have been applied to improve the overall performance of the system.
