Authors: Azevedo Érica de Melo
Published: November 2020

O presente trabalho tem como objetivo realizar uma análise do perfil dos estudantes ingressantes de um curso de Licenciatura em Química semipresencial do Sistema UAB. Foram realizadas pesquisas bibliográficas em portais de busca de artigo (Scielo, Google Acadêmico e Portal Capes) acerca de trabalhos publicados sobre licenciatura em química EAD e/ou semipresenciais em uma primeira etapa. A quantidade de resultados retornados foi muito ampla, porém genérica, já que a maioria dos trabalhos travava de ensino de química presencial ou metodologias para ensino de química. Por isso, procedeu-se a uma busca sobre ensino de Química EaD e/ou semipresencial nos Anais de dois Congressos Nacionais na área de química. Após essa pesquisa extensa, pode-se concluir que poucos trabalhos têm sido publicados nos dois Congressos analisados. Na segunda etapa foi aplicado um questionário aos alunos ingressantes deste curso. Foram feitas perguntas de cunho econômico, social e opinativo. A partir das respostas dos alunos, foram elaborados gráficos interpretativos, desenvolvendo uma discussão crítica acerca do perfil e da visão dos discentes em e relação as possibilidades, vantagens e desvantagens da modalidade de ensino.

Published: November 2020

O objetivo do estudo foi delinear o perfil dos professores e suas percepções sobre educação a distância (EAD) em cursos técnicos de pesca, aquicultura e recursos pesqueiros, durante a pandemia (COVID-19). O estudo foi realizado com 30 professores do Instituto Federal de Ciências da Educação e Tecnologia do Pará (IFPA). Utilizou-se um questionário semiestruturado on-line, com perguntas sobre a caracterização do professor e aspectos relacionados ao ensino a distância. Entre os professores, observou-se a predominância de homens, na faixa etária de 31 a 40 anos, solteiros, graduados e tecnólogos com mais de 10 anos de graduação concluídos e 50% de médicos. Identificamos que eles têm entre 3 e 5 anos de ensino e a maioria deles desenvolve atividades de ensino no curso técnico em aquicultura. Além do que, além do mais, priorizam metodologias teóricas e práticas, utilizando ferramentas tecnológicas em sala de aula. Além disso, eles ensinam as disciplinas e ficam satisfeitos no exercício de seu trabalho. Quando questionados sobre as interferências da pandemia no progresso escolar e a possibilidade de trabalhar em educação a distância, afirmaram que o semestre letivo foi comprometido e não está preparado para atuar nessa modalidade. Além disso, apontaram que a falta de acesso à Internet e aos computadores, nas residências dos estudantes, compromete a possibilidade de educação on-line para a continuidade do ensino. O Sistema Integrado de Gestão de Atividades Acadêmicas (SIGAA), foi apresentado como a principal ferramenta no ensino a distância. Em conclusão, a formação de professores e alunos em educação a distância.

O Ensino a Distância em Tempos de Pandemia e suas Adequações, Interações, Afetividades e Resultados
Authors: Dutra Jurandir , Sitoie Carlitos Luí­s
Published: November 2020

A última geração de Educação a Distância é a uma modalidade de ensino que pode combinar abordagens síncronas e/ou assíncronas e tem por objetivo democratizar o acesso à educação, podendo adotar as Tecnologias Digitais da Informação e da Comunicação por meio de plataformas virtuais interativas como mediadoras do processo de ensino-aprendizagem. Contudo, requer ainda a adoção de práticas de cibercultura (LEVY, 1999), resultante das relações entre pessoas e as tecnologias digitais em rede, como catalisadora motivacional da interação. O objetivo deste trabalho é apresentar o relato de experiência de uma oferta de disciplina nesta modalidade, com as adequações realizadas no cenário de pandemia de COVID-19, a alunos de um curso de mestrado matriculados na Universidade Save, residentes em Massinga-Moçambique, enquanto o professor ministrante, da Universidade Federal do Amazonas, residia na cidade de Manaus-Brasil. Ambas as cidades em graus diferentes de isolamento social. Manaus, em Maio/2020, estava sob o colapso do sistema funerário e de saúde pública, com restrições severas à mobilidade urbana e Massinga, em nível 3 de alerta da Organização Mundial de Saúde, permitindo, no máximo, encontros presenciais de até quatro pessoas. Com todas essas limitações, os encontros presenciais não poderiam ocorrer. Após dificuldades de sinal de internet, a interação em tempo real mostrou-se promissora apenas através do aplicativo WhatsApp. A partir daí foi notória a solidariedade, o comprometimento, o companheirismo e o envolvimento entre os alunos e o professor. Nesse espaço coletivo a afetividade e a cooperação fluíram.

Authors: Aprita Sari Cut Maya , Suhail Ghifari Muhammad , Talib @ Khalid Kartini Aboo
Published: November 2020

Purpose of the study: Within 10 years, the central government of Indonesia has granted the special autonomy fund to Aceh as a strategy to improve the welfare of Acehnese. Contrary, the special autonomy funds that cannot be implemented properly-affected to the poverty in Aceh-is not significantly decreased. This study aims to determine the failure of special autonomy funds to decrease poverty in Aceh.

Methodology: This research used descriptive qualitative methods by conducting the primary data through interviews, also secondary data through books, journals, newspapers, and other related sources. The analysis data is doing by using Transactional Political Theory.

Main Findings: The results of this study indicate that asymmetric decentralization can be seen from the weak Regional Economic Growth Rate and the slow improvement of the Quality of Human Development Index (HDI). Thus the failure was caused by two things, namely: the thick Political Content of The Local Political Elite and the Domination of Local Political Elite in the Management of Aceh's Special Autonomy Fund in the Compilation of Planning and Work Programs. The absence of control in the management of special autonomy funds is based on project performance without good planning, and the existence of interest-based planning in the management of special autonomy funds that based on populist activity programs following the wishes of politicians which have an impact on weak regional economic growth, slow index improvement of human development quality, high poverty rates, and high unemployment in Aceh.

Applications of this study: The finding of this study offered the evaluation systems for the government of Aceh to strengthen better local government governance, especially in increasing budget planning and implementation efficiency and strengthening regulations, and implementing an e-planning system to select program activities from the Aceh special autonomy fund.

Novelty/Originality of this study: Based on the literature review conducted, there were limited publications which are focusing on the failure of autonomy funds in Aceh. Therefore this research will enrich the publication that concerns the failure of managing special autonomy funds in Aceh.

Authors: Amirul Sharifah Rahama , Amirul Sharifah Milda , Mail Rasid
Published: November 2020

Purpose of the study: This paper aims to pioneer the investigation of human resource (HR) and management accounting (MA) realignment in delivering organizational working flexibility strategy. The core idea is to rebranding the HR and MA framework for strategic flexible working arrangements (FWA), so that FWA implementation or enhancement can be both effective and efficient.
Methodology: This study is based on the epistemological of the social constructivist approach and qualitative in nature. We conducted semi-structured interviews and analyzed the collected data by using thematic analysis.
Main Findings: The results revealed that HR and MA have overlapping responsibilities that add value to effective and efficient FWA implementation/enhancement. There is a definite prerequisite for HR and MA to sit together to manage employees' performance appraisal, compensation, and benefits. To ensure the efficiency of FWA, HR critically needs MA information such as budgeting, return on investment, variance analysis and, cost monitoring of FWA implementation/enhancement.
Applications of this study: This study provides insight beyond FWA adoption, whereby we proposed a framework for strategic FWA, which bridges the connection between HR and MA so that FWA implementation or enhancement can be both effective and efficient. We thoroughly discussed how the synergy between HR and MA can be achieved through several key elements, which is expected to yield strategic outcomes for the organization. Most importantly, the organization shall be able to overcome the redundancies between HR and MA roles to create a more compelling strategic planning for FWA implementation. Hence, leading towards greater strategic outcomes such as strategic dynamic acquisition, effective HR cost, a strategic link between HR outcomes and business, strategic return on investment, as well as comprehensive HRM measurement and performance.
Novelty/Originality of this study: The study developed a conceptual framework of HR and MA integration and strategic outcomes for FWA implementation. The features of this framework are of greater importance for FWA success and advance the notion of FWA literature by unveiling the strategic alignment between HR and MA.

Authors: Sufyan Abu , Rohmayani Yani , Chaeru Nugraha Tubagus , H. Al-Khresheh Mohammed
Published: November 2020

Purpose: This study aims to describe the forms of Arabic language interference on terminologies in the domains of science, technology, and art.

Methodology: The study was conducted morphophonologically using descriptive-analytical research methods. The descriptive-analytic research method was used to facilitate the achievement of goals specified in this study. The data findings were reviewed using the distributional method.

Main Findings: The study found that language interference is an aspect of vocabulary development and enrichment, which requires harmonization of speech sounds. The results showed that in the Arabic language, interference produced partial absorption and full absorption. Phonologically, partial absorption occurred through the absorption of sound elements at the beginning or end of a word.

 Applications: Understanding the issue of language transfer in the development of Arabic vocabulary is useful for non- native Arabic speakers. The findings can also help Arabic teachers revise their teachings methods accordingly.

Novelty/Originality of this study: This study contributed to a better understanding of the forms of phonological interference of foreign languages into the Arabic language. These forms can be represented as partial absorption, total absorption, and sound change. While in morphological forms, interference causes different developments of word patterns from classical Arabic.

Published: November 2020

Purpose of the study: This study is aimed to analyze the factors which influence the Intention of the Indonesian public to take personal protective measures and follow the stay-at-home order.

Methodology: This study was a cross-sectional study, using an instrument of an online questionnaire consisting of 75 questions. A total of 8 hypotheses, built on the foundation of the TPB and PMT model, was tested. The hypotheses were tested using a Structural Equation Modeling (SEM). An online questionnaire was distributed in May 2020 with the target population of the Indonesian public, especially the ones who have a stay-at-home order in their cities.

Main Findings: All 8 hypotheses were accepted. In the TPB model, It was revealed that Attitude (AT), Subjective Norms (SN), and Perceived Behavioral Control (PBC) significantly affect the public Intention to take personal protective measures. While in the PMT model, Perceived Vulnerability (PV), Perceived Severity (PS), Self-efficacy (SE), Response Efficacy (RE), and Response Cost (RC) have significant relationships with the public Intention to follow a stay-at-home order.

Applications of this study: Perceived Behavioral Control (PBC) is found to be a powerful predictor of the public Intention to take personal protective measures while for the compliance towards stay-at-home order, Response Efficacy (RE) is found to be a powerful predictor. Therefore, governments and public health organizations are encouraged to focus on giving educations to the public of how a stay-at-home order could be a crucial thing to do in combating COVID-19 promoting to the public that taking personal protective measures is a good thing and not a hard action to do.

Novelty/Originality of this study: We addressed COVID-19 in a novel way, which is understanding people's underlying psychological factors that influence particular COVID-19 related behaviors. By doing so, this study helps researchers and policymakers in making the appropriate policies and recommendations in slowing the spread of COVID-19.

Authors: Ghandour Ahmad
Published: November 2020

Purpose of study: The study aimed at establishing the implications of the COVID-19 pandemic on project delivery in the UAE with a significant focus on the construction industry. The study also sought to determine some of the negative implications of COVID-19 for the construction industry.

Methodology: The within-subjects research design was employed in the study. Purposive and simple random sampling was used in the selection of the respondents. A total of 116 project managers in the construction industry were sampled for the study. Data was collecting using self-administered online questionnaires. The SPSS software was applied to analyze the collected data using the paired samples t-test analysis method to compare the means of the projected number of days taken to complete a project before and during the COVID-19 period.

Main Findings: The study findings revealed that there is a statistically significant effect of the COVID-19 pandemic on the number of days taken to complete projects in the construction industry in the UAE. The findings of the study revealed that the pandemic resulted in a lack of access to raw materials and labor, thereby leading to a delay in the completion of projects.

Application of the study: The revelation of the implications would inform the policy and decision-makers in the country to devise effective ways of addressing the challenges for the stability of the sector. The researcher recommends the same study to be replicated in other areas to identify the effects the pandemic has had on other industries. Another study should also be conducted on the effective strategies that should be adopted to address the effects caused by the COVID-19 pandemic on the construction industry in the UAE.

Novelty/originality of the study: This is contemporary studies that deal with a current issue. The study concluded that the construction industry became a victim of COVID-19 to the extent that it has brought its projects to a halt and significantly eroded the market of its beneficiaries. Unlike other industries, construction projects cannot accommodate distance working but facing challenges making on-time delivery impossible and therefore construction industry is at risk.

Authors:   ,   Universidad Peruana de Ciencias Aplicadas (UPC), Burga Larco Gonzalo
Published: November 2020

En el corto plazo, el mundo atravesará una revolución por el desarrollo y uso creciente de tecnologías disruptivas en todas las dimensiones: social, económico y político. En este sentido, esta investigación propone identificar las percepciones de los principales stakeholders de IBM a raíz de las estrategias de comunicación externa que se han aplicado sobre el potencial uso de las tecnologías disruptivas. Se aplicó una metodología cualitativa con enfoque de Estudio de Caso, seleccionando a una muestra Homogénea y Conveniente a través de seis entrevistas y un focus group. Como resultado se obtuvo que sí existe interés en los peruanos por conocer qué son las tecnologías disruptivas, pero su difusión tiene un enfoque comercial que no está generando desarrollo o soluciones relevantes en el mercado local. Como aporte, los resultados de este trabajo también muestran la necesidad de difundir más casos locales de cómo la tecnología está generando desarrollo en Perú para que el conocimiento no recaiga únicamente en pequeñas élites de profesionales y estudiantes. Ello, a su vez, permitirá que la continuidad de las tecnologías disruptivas con las que trabaja IBM en el mercado local no estén en riesgo.

Authors: SZCZUCKA-LASOTA Bożena , WĘGRZYN Tomasz , ŁAZARZ Bogusław , JUREK Adam , WILCZYŃSKI Krzysztof I.
Published: November 2020

There is an increasing demand for mixed joints made of hard-weldable steels used in the construction of transport means. An illustration of this is the welding of movable platform elements such as a pin to arm joints. The pin is made of high-strength structural steel S690 QL (1.8928) while the arm of the movable platform is made of DOCOL 1200M steel from the AHSS group (Advanced High-Strength Steel). Such a joint is not easy to make due to the different chemical composition of both steels. The difference in thickness of welded elements creates an additional difficulty. The thickness of the cylindrical pin is 40 mm, whereas the thickness of the sheet metal used for the platform arm is much smaller and amounts to 2 mm. Joints of varying thickness and chemical composition tend to produce cracks in the heat-affected zone as well as in the weld. The purpose of this article is to determine the most appropriate welding parameters and the selection of additional materials to obtain correct joint with good mechanical properties, free of welding defects and incompatibilities.

Authors: KHABIRI Mohammad Mehdi , AFKHAMY MEYBODI Pooya , AFSHARI Abolfazl
Published: November 2020

Sidewalks play a very important role in the dynamism maintenance as well as the development of cities especially historic cities. To ensure the maintaining service quality of sidewalks, the first step is to prevent distress occurrence, thereafter repair the distress that occurred in the sidewalks. In historic cities, the lack of suitable sidewalks for walking led to the gradual elimination of pedestrians. Yazd is a historic city recorded as a world heritage site by UNESCO, which attracts many tourists from all over the world every year. Therefore, preserving the quality of sidewalks in this city is of great importance. In this research, the SCI method was used to investigate the condition of the sidewalks in the studied area. This method is similar to the pavement condition index (PCI) method. The results showed that the condition of sidewalks in the studied area is in the range of 55-70, which is relative.

Authors: KIRSCHENSTEIN Małgorzata , KRASUSKI Kamil , GOŚ Artur
Published: November 2020

This article presents the results of studies concerning the designation of accuracy in aircraft navigation positioning by means of the SPP and the SBAS code methods. The examination of the aircraft positioning accuracy was made in the aspect of the use of tropospheric correction in observation equations of the SPP and the SBAS positioning methods. The accuracy of the coordinates of the aircraft in the SPP and the SBAS solutions was referenced to the DGPS reference solution. The investigations were conducted on raw observation data and GPS navigation data in an air test in Dęblin. Based on the conducted calculations, it was proved that the lack of use of tropospheric correction in the SPP method causes an error in an aircraft position up to 18.5 m, and in the SBAS method up to 23.2 m. In addition, the statistical measure of RMS accuracy in the absence of applying the tropospheric correction in the SPP method results in an accuracy decrease to 8.6 m, and in the SBAS method to 12.2 m, accordingly.

Authors: CIEŚLA Maria , OPASIAK Tadeusz
Published: November 2020

The scientific purpose of this paper was to analyse the problem related to intermodal transportation of mining components packed in containers or other cargo transport units coupled with the problem of its proper securing. In this article, the issue of exposing the load to the effects of inertia forces which might cause unintentional movement is presented. The methods of securing the heavy load in cargo transport units are reviewed in the context of cargo immobilisation possibilities while reducing the load sensitivity to mechanical forces. The research part of this article presents the methods of packing and securing an atypical load, which is a part of a mining machine weighing 18t. This paper presents the results of calculations of inertia forces acting on the transported cargo, packed on a container platform. Based on the results, the cross fixing method was selected to secure the cargo and further decisions were made on the type and quantity of conveyor lashings necessary for the safe and correct carriage of the atypical load.
Transport decarbonisation in South Africa: a case for active transport
Authors: OLOJEDE Olorunfemi Ayodeji
Published: November 2020

Over two-thirds of greenhouse gases (GHG) emissions that contribute to climate change emanate from transport. This could double by 2050. With per capita emissions nearly twice the global average, South Africa ranks 13th globally on GHG emissions with road transport, directly and indirectly, accounting for 91.2% of total transport GHG emissions. It has been projected that by 2100, up to 100% increase in the country’s average temperature above the 20th century average rise. This has far-reaching implications, even for the transport sector. To decarbonise its transport sector, South Africa has committed to reducing its GHG emissions by 34% by 2020 and 42% by 2025, respectively, through pointed strategies and policies. However, efficient implementation of proposed measures and sufficient funding remain daunting challenges. Thus, this paper contends that adequate attention has not been paid to active transport in the country’s transport decarbonisation policy implementation despite its inclusion in policy statements. It then asserts that active transport is indispensable to South Africa’s achievement of its transport decarbonisation goals, especially when steps taken hitherto seem ineffective. Consequently, the right attitudes, regulatory instruments, and policy initiatives towards the promotion of active transport are recommended.

Globally, air transport has seen a greater increase in recent years. This manuscript is divided into three parts for analysing the negative effects of aviation. The first part is focused on the identification of sources of aircraft noise. While the second part of this article describes the basic principles of the construction and operation of an aircraft jet engine concerning the gaseous emissions produced by such an engine (Third part missing?). The main benefit of this article is the evaluation of the reliability of the human factor because the human factor is an integral part of technical systems and processes. Reliability assessment was performed using the TESEO method. The ergonomic parameter, that is, the cabin noise, was quantified in the given method. The measurement was performed on two types of aircraft, namely in the cabin of a transport jet aircraft and in the cabin of asmall transport aircraft equipped with turboprop engines.

Discussions on how urban space would be transformed by the use of autonomous vehicles (AVs) are scarce. This study identifies the impacts caused by the shared use of AVs on urban parking and urban space management. An estimation method was formulated considering the reduction in parking demand, the possible alteration in vehicle ownership, and the reallocation of urban space. A case study was performed in a 673,220 m2 area through scenarios created by using real data of parking spaces and the results of previous studies. Results showed that parking spaces can be saved with the use of shared AVs, which would allow the reallocation of urban space to new uses (for example, implementation of around 12,000 bike-sharing docking spots, 10 km bike lanes, 7 km additional traffic lane or 140 ‘parklets’). The results contribute to revealing the positive impacts of AVs.

The design dimensions of the executive hydraulic cylinders of the brake system of heavy-duty mining dump trucks cause high fluid flow during the braking process. Therefore, dimensions of the anti-blocking system modulator spool pair require unique electromagnets or hydraulic amplifiers to control. These solutions do not allow the required modulator performance. Thus, a modulator scheme with a division of the flow of fluid from the source to the brake cylinders was developed. This scheme allows during emergency braking passing, an additional amount of fluid to cylinders through the valve, installed parallel to the main valve upon pressure increase phase and controlled by the pressure difference. The task is to develop a method for calculating the main structural dimensions of a modulator. The calculation of the valve of the second cascade, installed in parallel to the main stage, is carried out for the emergency braking mode with the maximum flow rate to ensure the required performance of the braking system. The balance of fluid flows equations is compiled at the key points. The flow rate of the fluid through each of the valves is determined by the Torricelli formula, and the pressure difference across the valves is assuned equal. The obtained relations allows building a family of Q-p curves, which can be used to select the diameter and stroke of the additional valve depending on the flow rate in the brake system.

The lorry frame is the main carrying part of a lorry, composed of several components. These components are connected by joints into one structural unit and it forms the lorry chassis. The contribution of this article is focused on the strength analyses of a backbone frame, which is used on an off-road lorry chassis. Strength analyses are carried out utilising the finite element method. This article presents a created three-dimensional model of the frame and definition of boundary conditions (loads, the definition of degrees of freedom) needed for simulation computations. Results of the numerical calculations are the main parts of this article. Attention is mainly centred on the distribution of stresses of the frame under defined loads and its deformations.

Increasing transport volumes on Europe's inland waterways is a major reason for improving the quality and reliability of internationally important waterways. Continued navigation restrictions due to restricted draft (draught) led to the search for new design solutions. Such solutions enable navigation even under critical navigation conditions. Restricted draft is one of the most important limitations that hinder navigation, especially in the summer. The main objective of the construction of an inland vessel is to obtain a shape that will achieve optimum performance with as little resistance as possible. A shape that will be able to navigate at a limited depth. Presently, there is no clearly defined methodology as a procedure for optimising the hull. When solving theoretical problems of shipbuilding character and ship calculations, it is necessary to consider the basic theory of the ship with special regard to the latest methodological procedures of related scientific disciplines. This paper presents a methodology that considers all the basic aspects of optimisation tasks in ship design and construction.

Published: November 2020

In this paper, an experimental attempt has been made to improve the
performance and emission of a non-road diesel engine using adiesel aloe vera emulsified
fuel (A10). Two fuel samples such as neat diesel (D100) and diesel aloe vera emulsified
fuel referred to as A10 (10% aloe vera, 89% diesel, 1% surfactant) was used to conduct
the experiments and the obtained results were compared. The experiments were carried
out on a single cylinder non-road Genset diesel engine at low load (BMEP 1.54 bar), mid
load (BMEP 3.09 bar) and high load(BMEP 4.63 &6.18 bar) conditions.The experimental
results show that the dieselaloe vera emulsified fuel resulted in reduced nitric oxide (NO)
with increased brake thermal efficiency (BTE). overall, a 19.24% reduction in NO
emission and a 9.82% increase in BTE was observed. Also, it was noticed that the A10
prolonged the ignition delay and improved the air-fuel mixing inside the combustion
chamber.
Synergistic Effect of Trisodium citrate (TSC) on the Inhibition
Efficiency of Sargassum swartzii (SS) -Zn2+ System on Mild
Steel in Aqueous Environment

Published: November 2020

The aquatic plant kingdom is a treasure of potential bioactive compounds. Aquatic plants
contain some organic compounds that provide definite physiological actions on the human body. In
the present study deals with the synergistic effect of Trisodium citrate (TSC)on the inhibition
efficiency of methanolic extract of Sargassum swartzii (SS) and Zn2+ system on mild steel in
aqueous environment. The corrosion monitoring techniques adopted in the study were weight-loss
methods, electrochemical measurements, FT-IR and surface morphological techniques namely SEM
and EDX. It has proved the formulation consisting of 100 ppm of Zn2+, 120 ppm of SS and 100 ppm
of TSC has 95.77% IE. The high performance of SS - Zn 2+- TSC system could be due to synergistic
effect that covers a wide surface coverage area on the metal surface and thus retarding the corrosion.
Polarization study reveals that this formulation functions as a mixed inhibitor. AC impedance spectra
suggest the presence of protective film on the metal surface. FT-IR spectra reveals that the protective
film consists of Fe2+-SS complex, Fe2+-TSC complex and Zn (OH)2. SEM and EDX provide a
pictorial representation on the nature of surface film in the absence and presence of inhibitors. Thus,
it concluded that Sargassum swartzii - Zn 2+- TSC inhibitor system acted as a good inhibitor in
aqueous medium.

Solar selective materials and structure of solar thermal energy conversion
systems plays a prominent role for the improvement of optical properties. In the present
work simulations on multi-layered thin films have been conducted using code software
with Mo and Was functional layer in combination with bond layer and protective layers of
Si3N4 and Al2O3. The better combination is selected for optimization on thickness for
absorption and reflection. To simplify experimentation, Taguchi‟s design of experiments
approach was adopted to determine the optimum material layer combination.The results
indicate for multi-layered thin films that combination of Al2O3-Mo-Al2O3 has better
reflectance of 50.48% and combination Si3N4-W-Si3N4 has better absorptance of 74.81%
upon optimization on thickness of bond layers, functional and protective layers. These
results are discussed on main effect plots, contour plots and surface plots.
