The aim of this study is to point out the relationship between learning styles and the academic. The purpose of this study is to show the relationship between learning styles and academic achievement of 4th grade elementary students. The study was designed according to the convergent parallel design, one of the mixed research designs in which quantitative and qualitative research methods are used together. While the quantitative and qualitative data are collected together in accordance with the convergent parallel design, the data analysis is presented separately in the results section. The study group of the research consists of 163 grade 4 primary school students, 74 girls (n=74) and 89 (n=89) boys, taught in a government primary school in Istanbul Turkey. To find out whether learning styles predict academic achievement, linear regression analysis was conducted. On the other hand, descriptive analysis and content analysis were used in the qualitative data analysis. In this study, it was found that learning styles predict academic achievement. It was also found that students tend to discover their own learning methods, and depending on which method they prefer, the academic area in which they succeed differs.

Full textAbstract:
The reliable operating region, which is the set of all possible points in the design space that satisfy the reliability requirement, is capable to improve the reliability of products in the design stage. However, the reliable operating region has an irregular geometry shape and it is hard to derive an explicit expression; therefore, its practicality is poor. In order to obtain a more convenient approach, this paper proposes a reliable hyperrectangle operating region, which is expressed by permissible intervals for each design parameter and has the advantage that design parameters are decoupled. An iterative algorithm that seeks an axis-parallel reliable hyperrectangle with maximum volume is proposed. Starting from a design point with target performance, the lengths of the sides of the reliable hyperrectangle are iteratively updated. Theoretical analysis shows that the proposed algorithm is convergent. Furthermore, we extend the proposed methodology to deal with design space constraints. Some numerical examples and engineering cases demonstrate that the proposed algorithm can achieve the requirement of reliability efficiently.

This study examined undergraduate STEM students’ experiences using an online introductory computer programming learning environment equipped with an automated hint generation system. Following a convergent parallel mixed methods design, this study utilized both quantitative and qualitative data from student experiential data. Analysis by level of prior knowledge demonstrated that elements of the learning environment did not cater to their learning needs and cognitive architecture. Cognitive Load Theory was used to contextualize system elements against both higher and lower prior experience learners, ultimately pointing to a need to design better scaffolds and hints to the needs of novice CS learners.

Full textAbstract:
AbstractUsing quantitative and qualitative research designs, respectively, two studies investigated why countries make different health technology assessment (HTA) drug reimbursement recommendations. Building on these, the objective of this study was to (a) develop a conceptual framework integrating the factors explaining these decisions, (b) explore their relationship and (c) assess if they are congruent, complementary or discrepant. A parallel convergent mixed methods design was used. Countries included in both previous studies were selected (England, Sweden, Scotland and France). A conceptual framework that integrated and organised the factors explaining the decisions from the two studies was developed. Relationships between factors were explored and illustrated through case studies. The framework distinguishes macro-level factors from micro-level ones. Only two of the factors common to both studies were congruent, while two others reached discrepant conclusions (stakeholder input and external review of the evidence processes). The remaining factors identified within one or both studies were complementary. Bringing together these findings contributed to generating a more complete picture of why countries make different HTA recommendations. Results were mostly complementary, explaining and enhancing each other. We conclude that differences often result from a combination of factors, with an important component relating to what occurs during the deliberative process.

Full textAbstract:
Purpose – The purpose of this convergent parallel mixed methods paper is to explore the mentoring experience within the context of a science, technology, engineering and math (STEM) specific mentoring program for urban, at risk, high school youth, using the Principles of Adult Mentoring Inventory (PAMI) as an instrument that modeled effective mentoring behavior. The study took place at a large, urban, Midwestern university in the USA. Design/methodology/approach – A research design was developed and both quantitative and qualitative data were collected in parallel, analyzed separately and then merged to determine results. The PAMI instrument that measures six constructs of mentor effectiveness was administered to STEM mentors as a pre/post-test and enabled researchers to collect quantitative data. Researchers used focus groups to collect qualitative data in the form of transcribed interviews. This study sought to inform STEM mentoring program development by collecting both qualitative and quantitative data independently and simultaneously in order to confirm findings. Researchers used a convergent parallel mixed methods design to first, reinforce and corroborate the findings given the small sample size (n=8); second, minimize alternative interpretations from data gathering and analysis, third, make clear various factors contributing to the effectiveness of STEM mentoring. Findings – Throughout the mentoring experience, mentor perceptions of their mentoring abilities increased to be in the “more highly effective” range within PAMI. In five of the six constructs the results indicated mentors scored lower on the pre-test than they did on the post-test of the PAMI, meaning mentor perceptions of mentoring abilities improved overall during the course and the mentoring experience. Common themes from both quantitative and qualitative results were developed, are discussed using the PAMI constructs as organizers, and include communication, information, and gender differences. Originality/value – This study added to the dearth of literature and investigations surrounding STEM mentoring. Many studies have concentrated primarily on mentoring but few have investigated the concept of STEM mentoring program best practices. The results of this study provided a multidimensional look at STEM mentoring programs that impact urban, at risk, high school youth.

Parental involvement is linked with the higher academic achievement of the students. School Social Work is a significant field of social work discipline, which provides a liaison between school, children, their families and community, but is unfortunately lacking in our country. Students face many educational and social challenges which may lead them to leave school and increase dropout ratio which is currently a huge problem in Pakistan. The objective of this study is to explore the need for school social work by examining the parental involvement of public school students who demonstrate poor grades. Ecological theory is applied to explain the role of parents in the education of their children. Methodology of this study is based on convergent parallel design, a mixed method approach. Students of grades 6 & 10 of public schools of district Lahore, and their parents and teachers were the respondents of this study. Findings revealed that the students who demonstrated poor grades; their parental involvement in their studies was also poor. Need for school social work services was highly demanded by the teachers and parents to help improve these children’s grades.

Full textAbstract:
Accuracy of the finite difference sensitivity calculations are improved by
calculating the optimum finite difference interval sizes. In an aerodynamic inverse
design algorithm, a compressor cascade geometry is perturbed by shape functions
and finite differences sensitivity derivatives of the flow variables are calculated with
respect to the base geometry flow variables. Sensitivity derivatives are used in an
optimization code and a new airfoil is designed verifying given design
characteristics. Accurate sensitivities are needed for optimization process. In order to
find the optimum finite difference interval size, a method is investigated.
Convergence error estimation techniques in iterative solutions and second derivative
estimations are investigated to facilitate this method. For validation of the method,
analytical sensitivity calculations of Euler equations are used and several
applications are performed.
Efficiency of the finite difference sensitivity calculations is improved by
parallel computing. Finite difference sensitivity calculations are independent tasks in
an inverse aerodynamic design algorithm and can be computed separately.
Sensitivity calculations are performed on parallel processors and computing time is
decreased.

Full textAbstract:
Les systèmes de transport sont caractérisés de manière dynamique non seulement par des interactions non linéaires entre les différents composants, mais également par des boucles de rétroaction entre l'état du réseau et les décisions des utilisateurs. En particulier, la congestion du réseau impacte à la fois la répartition de la demande locale en modifiant les choix d’itinéraire et la demande multimodale globale. Selon les conditions du réseau, ils peuvent décider de changer, par exemple, leur mode de transport. Plusieurs équilibres peuvent être définis pour les systèmes de transport. L'équilibre de l'utilisateur correspond à la situation dans laquelle chaque utilisateur est autorisé à se comporter de manière égoïste et à minimiser ses propres frais de déplacement. L'optimum du système correspond à une situation où le coût total du transport de tous les utilisateurs est minimal. Dans ce contexte, l’étude vise à calculer les modèles de flux d'itinéraires dans un réseau prenant en compte différentes conditions d’équilibre et à étudier l’équilibre du réseau dans un contexte dynamique. L'étude se concentre sur des modèles de trafic capables de représenter une dynamique du trafic urbain à grande échelle. Trois sujets principaux sont abordés. Premièrement, des méthodes heuristiques et méta-heuristiques rapides sont développées pour déterminer les équilibres avec différents types de trafic. Deuxièmement, l'existence et l'unicité des équilibres d'utilisateurs sont étudiées. Lorsqu'il n'y a pas d'unicité, la relation entre des équilibres multiples est examinée. De plus, l'impact de l'historique du réseau est analysé. Troisièmement, une nouvelle approche est développée pour analyser l’équilibre du réseau en fonction du niveau de la demande. Cette approche compare les optima des utilisateurs et du système et vise à concevoir des stratégies de contrôle afin de déplacer la situation d'équilibre de l'utilisateur vers l'optimum du systèmeTransport systems are dynamically characterized not only by nonlinear interactions between the different components but also by feedback loops between the state of the network and the decisions of users. In particular, network congestion affects both the distribution of local demand by modifying route choices and overall multimodal demand. Depending on the conditions of the network, they may decide to change for example their transportation mode. Several equilibria can be defined for transportation systems. The user equilibrium corresponds to the situation where each user is allowed to behave selfishly and to minimize his own travel costs. The system optimum corresponds to a situation where the total transport cost of all the users is minimum. In this context, the study aims to calculate route flow patterns in a network considering different equilibrium conditions and study the network equilibrium in a dynamic setting. The study focuses on traffic models capable of representing large-scale urban traffic dynamics. Three main issues are addressed. First, fast heuristic and meta-heuristic methods are developed to determine equilibria with different types of traffic patterns. Secondly, the existence and uniqueness of user equilibria is studied. When there is no uniqueness, the relationship between multiple equilibria is examined. Moreover, the impact of network history is analyzed. Thirdly, a new approach is developed to analyze the network equilibrium as a function of the level of demand. This approach compares user and system optimums and aims to design control strategies in order to move the user equilibrium situation towards the system optimum

Full textAbstract:
Industry 4.0 represents both a vision and a concept that paves the way to the next industrial
revolution. The rise of new IT-technologies such as artificial intelligence, machine learning
and cyber-physical systems build the technological foundation of what is considered a
paradigm shift in how goods and services are developed, produced and delivered. While the
term was often criticised in the beginning as an empty promise that solely serves marketing
purposes, Industry 4.0 gained recognition fast with governments, research institutes and
corporations around the globe starting to invest into the idea. However, despite all the efforts
and resources spent to make the vision a reality, studies have shown that the implementation
of Industry 4.0 is far from being a smooth process, as companies need to rethink their entire
business strategies. In fact, the transformational process has been investigated from various
angles to provide companies with a compass that guides them through this challenging
transition. However, a systematic understanding of the forces and their magnetic features that
steer the needle into the future is still lacking. As a consequence, companies either hesitate to
embark on the transition or struggle to implement Industry 4.0 on a broader scale. In order to
address this shortcoming, this thesis seeks to synthesise the strongly fragmented knowledge
about the factors that have an impact on the implementation of Industry 4.0 and to evaluate
their importance for companies.
The main objective of the thesis is addressed through three distinct publications. A systematic
literature review has been conducted in Publication 1 to identify the factors that need to be
considered when companies implement Industry 4.0. Based on this approach, the study
identifies 14 factors, discusses their theoretical meaning, and proposes three categories to
distinguish between them. Based upon these findings, Publication 2 assesses the importance of
the previously determined implementation factors through the application of a convergent parallel mixed-study design which is based on surveys with 140 Industry 4.0 practitioners and
in-depth interviews with 16 Industry 4.0 experts. In that context, results show that the factors
are not equally important and that five key factors play an elementary role when it comes to
the transitional process. What is more, the findings show that the importance of certain factors
varies throughout the life cycle of the transition and that the practitioners’ perception has an
impact on the perceived importance of the factors. Publication 3 complements the finding of
the previous two studied by illustrating and visualising the relationship between the previously
identified and assessed factors through the combination of network theory and systems
thinking. This approach offers a new perspective on the importance of the implementation
factors by showing that the importance of the examined factors is not static and that it changes
depending on the relationship to other implementation factors. Consequently, the findings lay
the foundations for the development of quantitative models that can be used to simulate specific
implementation scenario.Thesis (Ph.D.) -- University of Adelaide, Business School, 2021

Full textAbstract:
Research Doctorate - Doctor of Philosophy (PhD)The construction industry plays a significant role in developing and developed nation’s growth. It has been criticised as unsustainable because it impacts negatively on the environment and makes onerous demands on natural resources. Therefore researchers, policy makers, governments and non-governmental organisations have recognised the need to promote sustainable construction. Nigeria, one of Africa’s fastest-growing economies and the most populous, is endeavouring to implement sustainable practices. Its construction industry is viewed as lacking sustainable construction approaches such as waste management. The industry is heavily dependent on natural resources and its activities contribute to environmental degradation. A number of studies have identified high volumes of waste and this has highlighted the need for alternative approaches to the current traditional method of construction linked to the linear economy. The circular economy is a concept that integrates material repair, reduction, reuse, and recycling. Although the circular economy has not been applied in Nigeria, it has been adopted in the manufacturing, steel, and agricultural sectors in countries like China, Scotland, and Finland, while others are considering its adoption. The circular economy requires a holistic approach to be effectively and efficiently mainstreamed. Despite its advantages, there has been little investigation of its adoption for the Nigerian construction industry. The aim of this study is to develop a circular-economy-based construction material waste minimisation framework for Nigeria with a view to achieving sustainable construction. The objectives are, first, to identify types, causes, and methods of disposal for material waste. Second, to investigate the awareness, attitudes, and perceptions of Nigerian building construction firms to material waste minimisation. Third, to investigate current approaches to material waste minimisation at the design, procurement, and construction phases. Fourth, to investigate the extent to which the 3R principle has been adopted. Fifth, to identify policies or legislative measures and implementation methods for waste minimisation. Finally, to develop a circular-economy-based construction waste minimisation framework and investigate readiness for its adoption by Nigerian building construction firms. This study is founded on literature about construction waste management, the Nigerian construction industry, construction processes and phases as well as sustainable construction. The concept of the circular economy, including its origins, definitions, principles, characteristics, approaches, drivers, challenges, and benefits have been reviewed. The foundations of the circular economy and theoretical perspectives underpinning its integration have also been reviewed. This study has been viewed from a pragmatic philosophical stance that encourages the use of methods appropriate for the problem. A convergent parallel mixed methods approach was employed to obtain primary data from building construction firms in Lagos, Nigeria. Using a concurrent triangulation design, data obtained from a questionnaire survey were triangulated with data from semi-structured interviews and direct observation. Secondary data were collected via a traditional literature review. Quantitative data were analysed using SPSS. The tests conducted are the relative importance index analysis, factor analysis, Kruskal-Wallis test, and the Spearman’s rank correlation. Qualitative data were analysed through thematic analysis using NVivo 11 to identify key themes, relationships, coding, and sorting into categories. To ensure reliability and validity of the questionnaire data, a Cronbach’s Alpha test was conducted, with a result of 0.83 indicating good reliability and validity. A rigorous process, including a review of the research problem, design, and interview questions, as well as six rechecks of interview transcripts, ensured reliability and generalisability of the qualitative data. Findings suggest that concrete, timber products, and offcut tiles are the main types of waste generated in the Nigerian construction industry. The causes of these types of waste at the design, procurement, and construction phases are design changes, substandard materials, and quality of supervision, respectively. Nigerian building construction firms demonstrate a high level of awareness of the effects of material waste, while exhibiting positive attitudes to waste minimisation. However, their perceptions vary, although the majority perceived environmental protection as an important factor for waste minimisation. The relationships between the Nigerian building construction firms’ awareness, attitudes, and perceptions indicate that these are influenced by their perceptions. Furthermore, the study reveals that design for material optimisation is the design approach most frequently embraced to minimise waste, while design for reuse and recycling is the least frequently used. The most significant procurement approach adopted by the Nigerian building construction firms is to purchase durable materials. A factor analysis of procurement approaches was conducted, and two factors labelled “act green” and “buy green” were extracted. For construction approaches, stock control, effective team work, and avoiding excavation of unnecessary soil were identified as the most important processes, while factor analysis of construction approaches yielded three factors, namely: strategies, techniques, and operations. These approaches to waste minimisation differ among medium and large-scale construction companies. Additionally, the research has revealed reuse of formwork and scaffolding as the most significant approach of the 3Rs principle (reduce, reuse, and recycle). A factor analysis of the 3Rs approaches to waste minimisation yielded three factors, labelled “reduce”, “reuse”, and “recycle”. Site waste management planning is considered by Nigerian building construction firms as the most important policy to minimise waste. Two factors labelled “recommended” and “required” policies were extracted from the factor analysis of policies and regulations for ease of description and understanding. The key implementation methods are policy and education/training of the construction workforce. However, more than half of the firms surveyed do not have an organisational policy on waste minimisation, while 89.3% were keen to adopt a new waste minimisation method. Following these findings, a circular-economy-based construction waste minimisation framework was developed based on the diffusion of innovation theory. The framework consists of five sections, which are: identification of waste minimisation needs, assessment of existing minimisation measures, policy identification and formulation, identification of implementation methods, and evaluation of the proposed framework. This study has established a framework that can be used as a baseline for waste minimisation in the Nigerian construction industry while contributing to gaps identified in the body of knowledge. Adoption of the framework by Nigerian building construction firms and the Nigerian construction industry in general has the potential to reduce waste generated and landfilled. Recommendations are made for policy, training and education, changes in organisational culture and attitudes, best practices, and research and development. The study concludes by identifying future research areas.

Full textAbstract:
To date, there has been little, if any, holistic evaluation of one of the BankSETA programmes that bank employees are nominated to attend, the Certificate in Management Development (CMD). The programme began in 2010 with the aim of increasing the pool of skills in entry-level management occupations in the banking and micro-finance sector (BankSETA, 2016). In order to verify whether the CMD programme has achieved the purpose for which it was instituted by the BankSETA, it is important that a programme evaluation be conducted.
The main aim of this study was to undertake a holistic evaluation of the CMD programme to determine students’ perceptions, their increase in knowledge, their ability to apply on-the-job learning and the impact of the programme on the organisation. It also aimed to identify any barriers or obstacles and to provide recommendations to the BankSETA.
Kirkpatrick’s (1996) four-level model of reaction, learning, behaviour and results was used as the theoretical framework for this study. A convergent parallel design was used to gather and analyse the data. The convergent design allowed the researcher to use quantitative and qualitative data-collection methods simultaneously, prioritising the methods equally and keeping each phase independent during analysis, and to then mix the results during the overall interpretation of the findings.
The findings of this study highlight the importance of programme evaluation and how indispensable this practice is to the success of any programme. Even though positive results were conveyed at every phase of the study, there are certain areas that can be improved upon in order to maximise the outcomes of the CMD programme.Business Management

Full textAbstract:
There are mounting concerns to ensure that children are prepared for the literacy demands of the 21st century. Reading inability at 9 years of age portends a lifetime of illiteracy for the majority of struggling readers. Given the greater weight placed on expository text from the junior grades onwards, children with reading disabilities become increasingly constrained by their reading deficits, putting them at risk of falling ever further behind their normally achieving peers. This ethnographic study, extending over an 8 month period and finishing on the last day of the school year, targeted older poor readers at the junior level. Less is known about their reading deficits, relative to younger struggling readers. Therefore, the first of three principal objectives aimed to extend understanding of the processes whereby older poor readers interact with expository text by providing a qualitative finer-grained assessment of their particular difficulties than presently exists. The second objective was focused on developing and implementing a cohesive program of research-based interventions that targeted critical requirements of successful interactions with expository text, including the ability to summarize, locate information, and attend to text structure. The third objective involved establishing and describing a collaborative, intensive research partnership with two classroom teachers at the junior level to implement and evaluate research-grounded interventions for their students with reading difficulties, working within the context of the regular classroom. The dual researcher role, as collaborator with the teachers and instigator of the intervention program, shaped a reconfigured model of special education, responsive to a diverse range of student needs and abilities, and situated within a content-rich, challenging curriculum. Parallel lessons afforded the opportunity to tier instruction with increasing intensity for the children with the highest needs. Results showed the critical importance of aggressively promoting self-efficacy, self-regulation, and metacognitve awareness for older struggling readers. As these children’s strategic repertoire increased, so, too, did their comprehension and comprehension-monitoring. Differentiated instruction that was tiered, flexible, and responsive supported social inclusion and social collaboration. Social context and authentic content became interwoven and instrumental in engaging the children, maintaining their motivation and sustaining their commitment to read to learn.Thesis (Ph.D, Education) -- Queen's University, 2010-01-27 15:10:03.202

The growth of modern medicine, is paralleled by substantial growth in psychopharmaceutical medications designed to treat psychiatric disorders, pain, cognitive dysfunction, mental distress, and sleep disorders. These medications, many of which have high dependence potential, are primarily distributed through a prescription system. Diversion of psychopharmaceuticals from this system for non-medical use constitutes a substantial part of the illicit drug market in a growing number of countries. While there is considerable criminal or organized diversion from the prescription system, much of the leakage happens informally, often at the consumer/patient end of the distribution or availability chain. Modern technologies, including Internet-based market elements and new synthetic medications, are blurring the boundaries between medicines and illicit drugs, especially in affluent countries. The pathways of availability and distribution for non-medical use of ‘illicit drugs’ and of psychopharmaceuticals are thus increasingly converging and overlapping.

COVID-19 has presented new challenges for all teachers, especially teachers of students with special needs. Students have struggled with online learning environments with limited opportunities for social interaction and resources. The study investigated a co-design process to help teacher leaders to design inquiry-based learning with the integration of artificial intelligence (AI) technologies. The study utilized the convergent parallel mixed methods approach to analyze both qualitative and qualitative data to capture how teacher leaders introduced inquiry-based learning in the school community. The quantitative analysis revealed shifts in terms of teachers' ability to design inquiry-based projects that integrated AI. The qualitative analysis showed that the growth pattern of teacher leaders might be dependent upon (1) the usefulness of AI, (2) teachers' attitudes about the role of the teacher as a designer, and (3) perceived leadership support. The study provided a co-design process to engage teachers in designing inquiry-based projects during the pandemic times.

Full textAbstract:
The number of science, technology, engineering, and mathematics (STEM) jobs available in the United States will soon outnumber those qualified to fill them. Equally concerning is the decreasing number of students pursuing STEM careers. Standards-based virtual field trips (VFTs) are a promising strategy to support student interest in science and STEM fields, as well as meet the educational needs of teachers and students. VFTs provide students opportunities to connect with academic content in contextualized ways regardless of location and logistical restrictions. This convergent parallel mixed methods study investigated the impact of VFT programs on elementary students' interest in specific science domains and STEM fields. Findings showed a non-statistically significant increase in participants' interest in science domains and STEM. Further, findings suggest that prior interest and role-based scenarios promote an increase in science and STEM interest. Implications for research and practice are discussed in this chapter.

Full textAbstract:
Textbook theory seems to be at the farthest level from the most abstract categories, and it is repeatedly associated with in the current study. The connection of the principal fundamental categories of invariance and binarism are not even superficially traced to the traditional textbook theory inventory. The numerous conceptions of predication predominantly deal with its logical frames. The aim of the chapter is to explicate some hidden links between the levels of the conceptual vertical. The idea of invariance is embodied by the continuous iteration of binary predicative units originally incompressible in terms of their constituents and structure. Binary opposition is the category indissolubly active at every stage of speech generation. There have been found four functional patterns produced by a particular predicative operation. Each pattern correlates with all types of speech but to various extents, accenting some of them. They are parallel transfer, inverse transformation, convergent or divergent pivot structuring, and zooming.

Air mixed convection in a convergent channel with the two principal flat plates at uniform heat flux is analyzed numerically. In the considered system two parallel adiabatic extensions are placed downstream the convergent channel. The forced flow is obtained by imposing a pressure drop between the inlet and the outlet of the channel. The flow in the channel is assumed to be two-dimensional, turbulent and incompressible. A k-ε turbulent model is employed. Results in terms of dimensionless wall temperature distribution as a function of the walls converging angle, the Grashof number and the pressure drop are presented in the ranges: 0 ≤ ΔP ≤ 2.2·107, 2.8·104 ≤ Gr ≤ 2.1·105. Results show that increasing the angle of converging the Reynolds number increases at the same pressure drop. The larger the pressure drop the smaller the contribution of the free convection to the Reynolds number. Increasing the converging angle only slightly increases the ΔP value for which the effect of free convection is negligible.

Mixed convection in air in a convergent channel with the two principal flat plates at uniform heat flux is analyzed numerically by Fluent code. In the considered system two parallel adiabatic extensions are placed downstream of the convergent channel. The forced flow is obtained by imposing a pressure drop between the inlet and the outlet of the channel. The flow in the channel is assumed to be two-dimensional, turbulent and incompressible. A k-ε turbulent model is employed. Results in terms of dimensionless wall temperature distribution as a function of the walls converging angle, the Grashof number, the pressure drop and the channel aspect ratio are presented in the ranges: 0° ≤ θ ≤ 10°; 4.10 102 ≤ Gr ≤ 32.1 105, 0 ≤ ΔP ≤ 8.82·107, 10.15 < Lw/bmin < 58.0. Results show that Reynolds number, and then the mass flow rate flowing in the channel, increases at decreasing aspect ratios, Lw/bmin. The converging angle that optimizes the fluid-dynamic within the channel is equal to 5°. Dimensionless maximum wall temperature values decreases at increasing Reynolds number and the larger the aspect ratio, the larger the decrease. The Reynolds number over which natural convection become negligible, with respect to forced convection, increases at increasing converging angle and at decreasing aspect ratio.

Full textAbstract:
A numerical investigation of mixed convection in air in a convergent vertical channel, due to the interaction between a buoyancy flow and a moving plate induced flow, is presented. The plate moves at a constant velocity along the buoyancy force direction and the principal inclined walls of the channel are heated at uniform heat flux. The numerical analysis is carried out by means of the finite volume method, using the commercial code Fluent. The effects of the channel spacing, wall heat flux, moving plate velocity and converging angle are investigated. Heated wall temperature increases at increasing converging angle, except for natural convection in a 10 mm minimum channel gap. The effect of the converging angle on the wall temperatures is less marked at the larger channel spacing. Maximum temperature of the moving plate is attained in the parallel wall channel for a 30 W m−2 wall heat flux, both in the 10 mm and 40 mm channel, whereas for a 220 W m−2 wall heat flux in the 40 mm channel in mixed convection, maximum wall temperatures are exhibited for a 10° angle. Nusselt, Reynolds and Richardson numbers are correlated by a monomial equation for each converging angle and a unique monomial correlation for all investigated angles in the 2.1·10−2 – 5.1·105 Richardson number range is presented.

Full textAbstract:
In distributed design processes, individual design subsystems have local control over design variables and seek to satisfy their own individual objectives, which may also be influenced by some system level objectives. The resulting network of coupled subsystems will either converge to a stable equilibrium, or diverge in an unstable manner. In this paper, we study the dependence of system stability on the solution process architecture. The solution process architecture describes how the design subsystems are ordered and can be either sequential, parallel, or a hybrid that incorporates both parallel and sequential elements. In this paper we demonstrate that the stability of a distributed design system does indeed depend on the solution process architecture chosen and we create a general process architecture model based on linear systems theory. The model allows the stability of equilibrium solutions to be analyzed for distributed design systems by converting any process architecture into an equivalent parallel representation. Moreover, we show that this approach can accurately predict when the equilibrium is unstable and the system divergent when previous models suggest the system is convergent.

Full textAbstract:
Solar chimney is a new method to produce electrical power. It employs solar radiation to raise the temperature of the air and the buoyancy of warm air to accelerate the air stream flowing through the system. By converting thermal energy into the kinetic energy of air movement, solar chimneys have a number of different applications such as ventilation, passive solar heating and cooling of buildings, solar-energy drying, and power generation. Moreover, it can be employed as an energy conversion system from solar to mechanical. A component, such as a turbine or piezoelectric component, set in the path of the air current, converts the kinetic energy of the flowing air into electricity. In this paper, a numerical investigation on a prototypal solar chimney system integrated in a south facade of a building is presented. The chimney is 4.0 m high, 1.5 m wide whereas the thickness is 0.20 m for the vertical parallel walls configuration and at the inlet 0.34 m and at the outlet 0.20 m for convergent configuration. The chimney consists of a converging channel with one vertical wall and one inclined of 2°. The analysis is carried out on a three-dimensional model in airflow and the governing equations are given in terms of k-ε turbulence model. The problem is solved by means of the commercial code Ansys-Fluent. The numerical analysis was intended to examine the effect of the solar chimney’s height and spacing. Further, comparison between radiative and non-radiative model is examined and discussed. Results are given in terms of wall temperature distributions, air velocity and temperature fields and transversal profiles for a uniform wall heat flux on the vertical wall equal to 300 W/m2. Thermal and fluid dynamics behaviors are evaluated in order to have some indications to improve the energy efficiency of the system.

Full textAbstract:
This paper presents details of the geometry, fabrication, and pumping performance of an electrohydrodynamically (EHD) driven thin film evaporator with a new electrode design. The operation principle of the device is based on the action of the EHD force on molecules of a dielectric liquid in a highly convergent electric field starting at the end of a pair of electrodes, where the electric field changes from zero to a finite value in between the electrodes. This force drives the liquid into the spacing between the electrodes. Because the electrodes are microfabricated very thinly on a surface, the liquid can be held within microns in thickness over the surface. The new design is a modification of the original device with parallel electrodes. The electrodes in the new design were fabricated in a splayed configuration with the narrow side dipped in the liquid. A relatively large (32 mm × 32 mm) area was covered with the splayed electrodes. The electrodes were fabricated through a lift-off process. It was found that a higher voltage can be sustained between the electrodes prior to breakdown threshold and a pumping head of about three times more than that of the parallel electrode configuration was achieved in the new design.

In distributed design individual designers have local control over design variables and seek to minimize their own individual objectives. The amount of time required to reach equilibrium solutions in decentralized design can vary based on the design process architecture chosen. There are two primary design process architectures, sequential and parallel, and a number of possible combinations of these architectures. In this paper a game theoretic approach is developed to determine the time required for a parallel and sequential architecture to converge to a solution for a two designer case. The equations derived solve for the time required to converge to a solution in closed form without any objective function evaluations. This result is validated by analyzing a distributed design case study. In this study the equations accurately predict the convergence time for a sequential and parallel architecture. A second validation is performed by analyzing a large number of randomly generated two designer systems. The approach in this case successfully predicts convergence within 3 iterations for nearly 98% of the systems analyzed. The remaining 2% highlight one of the approach’s weaknesses; it is susceptible to numerically ill conditioned problems. Understanding the rate at which distributed design problems converge is of key importance when determining design architectures. This work begins the investigation with a two designer case and lays the groundwork to expand to larger design systems with multiple design variables.

Full textAbstract:
The prediction of the plastic collapse load of cylindrical pressure vessels is very often made by using expensive Finite Element Computations. The calculation of the collapse load requires an elastic-plastic material model and the consideration of non-linear geometry effects. The plastic collapse load causes overalls structural instability and cannot be determined directly from a finite element analysis. The ASME (2007) code recommends that the collapse load should be the load for which the numerical solution does not converge. This load can be only determined approximately if a expensive nonlinear analysis consisting of a very large number of sub steps is done. The last load sub step leading to a convergent solution will be taken as the critical load for the structure. In the instability regime no standard finite element solution can be found because of the lack of convergence of the numerical procedure. Other methods for the calculation of the allowable pressure proposed by the ASME code are the elastic stress analysis and the limit load analysis. In the present paper the plastic collapse load for a cylindrical pressure vessel is determined by an analytical method based on a linear elastic perfectly plastic material model. When plasticity occurs the material is considered as incompressible and the tensor of plastic strains is parallel to the stress deviator tensor. In that case the finite stress-strain relationships of Henkel can be used for calculating the pressure for which plastic flow occurs at the inside of the vessel wall or in the case of full plasticity in the wall. The analytical results are fully confirmed by finite element predictions both for axisymmetric and high costs three dimensional models. The analytical model can be used for fast predictions of the allowable load for the design of a large variety of pressure vessels under safety considerations. The accuracy of the predicted collapse load largely depends on the quality of the temperature dependent wall material data used both in the analytical and numerical calculations.

During the design of complex systems, a design process may be subjected to stochastic inputs, interruptions, and changes. These design impulses can have a significant impact on the transient response and converged equilibrium for the design system. We distinguish this research by focusing on the interactions between local and architectural impulses in the form of designer mistakes and dissolution, division, and combination impulses, respectively. We find that local impulses tend to slow convergence but systems subjected to dissolution/division impulses still favor parallel arrangements. The strategy to mitigate combination impulses is unaffected by the presence of local impulses.
