A new species of anthothelid octocoral (Cnidaria, Alcyonacea) discovered on an algal reef of Taiwan
Authors: Tu Tzu-Hsuan , Dai Chang-Feng
Published: March 2022

A molecular phylogenetic analysis of 132 octocoral species reveals a close relationship between specimens collected from the intertidal pools of the Datan Algal Reef, Taoyuan, Taiwan, and Erythropodium caribaeorum (Duchassaing & Michelotti, 1860), but the two species have distinct morphological features. On the basis of morphological differences in polyps and sclerites, we identify and describe a new Erythropodium species: E. taoyuanensissp. nov. The distinct identifying features of E. taoyuanensissp. nov. include the upright contractile polyps from thin encrusting membranes and abundant 6-radiate sclerites. Using an integrative approach, we present the findings of morphological comparisons and molecular phylogenetic analyses to demonstrate that E. taoyuanensissp. nov. is distinct from other Erythropodium species. Our study contributes to the knowledge of octocoral biodiversity in marginal habitats.

Professional Training for Industrial Accident Prevention with Time Travel Games
Authors: Arnold Oksana , Franke Ronny , Jantke Klaus P. , Wache Hans-Holger
Published: March 2022

Industrial accident prevention is a critical problem to avoid loss of human lives, injuries, damage of installations and financial losses. Training is only effective and sustainable, if the human trainees are affected by their training experiences.  Time travel games, in general, and time travel prevention games, in particular, are an innovative category of edutainment media having high potential in areas such as environmental education and prevention training. Time travel prevention games for purposes such as accident prevention in the industries are advantageous due to their conservation of resources including human health and lives. They are af-fective by allowing for unprecedented learner/player/trainee experiences and they are effective due to the fascination of application-oriented game play including opportunities to influence the fate, the latter being less close to reality, but the more attractive and worth telling. Digital storyboarding is the ultimate design methodology allowing for properly dovetailing pedagogical and game design. It works simultaneously bottom-up, top-down or both at once in interdisciplinary teams flexibly in space and time. Storyboarding is the organization of future learner/player/trainee experiences. The expressive power and the reach of digital storyboarding is due to its roots in dynamic plan generation for the mastery of disturbances in the industries. The technology particularly supports the design of time travel adaptive to the players’ needs and goals aiming at affective experienc-es and effective learning.
A Structured Process for Supervising Students’ Final Theses and Projects in Computer Science
Authors: Schefer-Wenzl Sigrid , Miladinovic Igor
Published: March 2022

Bachelor’s and Master’s theses are an opportunity for students to dive deep into a research question and gain in-depth knowledge about a research topic. At the end of a curriculum, theses act as a kind of bridge between the educational stage and work or further study. Thesis supervision is a resource-intensive task and often a critical factor for the quality of a thesis. After decades of experience with different methods, we have developed a concept for continuous thesis supervision and applied it to two specific degree programs at our university, the Bachelor's program in Computer Science and Digital Communication and the Master's program in Software Design and Engineering. Compared to traditional supervision methods, this concept has led to a higher adherence to deadlines and to a higher quality of the final theses. In this paper, we present our findings on different types of supervisors and our concept for continuous thesis supervision, which can be adapted to each identified supervisor type. This concept comprises several methods, intended to inspire other supervisors to choose the set of methods that best suits their needs. We also describe how this concept can be adapted for project-based courses.
Research for a Teaching Approach: An Example of Addressing the High School Students’ Conceptual and Reasoning Difficulties in the Study of Direct Current Simple Electric Circuits
Authors: Vavasis Gerasimos , Kapotis Efstratios , Tombras George
Published: March 2022

With this work we aim at presenting a research on high school students’ (ages 16-17, Greece 2015-2017) understanding into the study of basic direct current (DC) circuits. Studies on this subject in over the world have contributed to a rich research base. Students’ conceptual and reasoning difficulties are presented and analyzed, aiming at the development of methodologies and teaching approaches, accompanied by instructional material to resolve them. The difficulties experienced by these students indicate a significant discrepancy between their conceptions and the scientific view. To address these difficulties, the design and the development of two types of programs were chosen. The first is based on educational models in the laboratory and the second consists of auxiliary courses and educational material for its simultaneous use in classroom teachings. The conclusion is that the existing literature is confirmed and enriched with new findings, while a different teaching approach accompanied by appropriate educational material seems to help the address of the conceptual and reasoning difficulties.
Chapitre 7. Une vaste implantation épigravettienne dans la vallée du Gallero
Authors: Olive Monique , Le Jeune Yann , Tomasso Antonin , Valentin Boris
Published: March 2022

En plus de la découverte d’un habitat épigravettien enfoui profondément dans une séquence tardiglaciaire, les prospections archéologiques ont aussi permis de récolter en surface de l’industrie lithique sur les deux rives du Gallero. Trois locus principaux (CDP 7, 10 et 15) ont fait l’objet d’une étude particulière. L’interprétation chrono-culturelle de l’industrie ramassée sur ces locus se fonde sur une analyse typo-technologique et économique et sur des observations stratigraphiques. Le matériel de surface est confronté à celui trouvé en fouille et des comparaisons sont effectuées avec d’autres sites italiens récemment étudiésLes assemblages récoltés sur les locus CDP 10 et 7 sont constitués de deux lots chronologiquement distincts. La composante majoritaire est épigravettienne et est rapprochée de séries de la fin de l’Épigravettien ancien. La composante plus récente est difficile à dater mais ne peut être antérieure au Mésolithique récent en raison de la présence de nucléus, débités par percussion indirecte. Le locus CDP 15 apparaît plus homogène et présente des affinités avec des séries de l’Épigravettien récent. Les observations stratigraphiques effectuées sur ces trois locus s’accordent avec l’analyse techno-économique et confirment l’existence d’au moins deux phases d’occupations épigravettiennes dans la vallée du Gallero : l’une, datée de 17 000-18 500 cal. BP, est grossièrement contemporaine de l’habitat enfoui, l’autre, plus récente, s’est probablement produite entre 13 000 et 15 000 cal. BP, durant l’interstade Bølling-Allerød. Enfin, à l’époque holocène, la vallée du Gallero a encore connu d’autres occupations plus tardives.

SLIC-Based Cloud Removal Approach with Inpainting for Landsat 8 SAR Images
Authors: Pillalamarri Vaishnavi , Gladston Angelin
Published: March 2022

Clouds which exist in optical remote sensing images can degrade their applicability for earth observation. Ground-cover information is degraded by thin clouds or even completely occluded by thick clouds, which limits further analysis and applications. Thus a SLIC based cloud removal approach is formulated for clustering the similar superpixels and forming Column Stack. Group Sparsity Constrained Robust principal component analysis is used to detect cloud and generate a column stack mask. Discriminative Robust Principal Component analysis is conducted to remove clouds. Finally inpainting is performed by finding the similar patches to obtain the gaps filled. The experimental results of reconstructed Landsat 8 real images are compared with the Landsat 7 real images using PSNR and RMSE. The values for PSNR are varying from 25 in Landsat 7 Real images to 90 in Landsat 8 reconstructed real images in Green channel and RMSE has changed from 175 in Landsat 7 real images to 3 in Red channel. This indicates that Landsat 8 reconstructed real images have greater quality and error rate in less.

Published: March 2022

Finite element simulation using ANSYS software, to analyze the effect of coating layers of different materials on piston compression ring. Similar material properties to that in the actual structural piston-compression-ring were considered on the simulated model. Three different coating materials, MgZrO3, La2Zr2O6, 3YSZ, and NiCrAl as bond coat materials of 1.6 mm thickness, were chosen to investigate the deformation, von Misses stress-strain, temperature distribution, heat flux of the core and coating layers. The results showed that the total elastic deformation was maximum for coating type MgZrO6, which was equal to 1.767 µm, and was higher by 0.46 times than uncoated ring. While, maximum von Misses stress was observed for coating type La2Zr2O6, which was higher by 1.69 times than that of the uncoated ring. Moreover, the maximum elastic strain was for type MgZrO6, which was equal to 0.003576, higher by 12.33 times comparing with the uncoated ring. Also, temperature rise and heat flux were maximum in the case of the uncoated ring.
Window Analysis and MPI for Efficiency and Productivity Assessment Under Fuzzy Data
Authors: Al-Refaie Abbas
Published: March 2022

This research develops a procedure for DEA window analysis and MPI evaluation of a manufacturing process with fuzzy inputs and outputs. A real case study was provided to illustrate relative efficiency and MPI assessment of a blowing machine over a period of one a year. The proposed approach was implemented to measure the technical, pure technical, and scale efficiency scores for decision making unit. The results showed that the blowing process was technically inefficient due to scale inefficiency. Therefore, management should optimize the size of operations and better utilize resources. Then, the lower and upper MPI values and their corresponding technology change and efficiency change were calculated. The MPI results revealed the reasons behind MPI progress or regress in current period measured with respect to next period. This procedure provides great assistance to process engineering in obtaining reliable feedback on process performance and guide them to take proper actions.

Published: March 2022

Duplex and super duplex materials possess the properties of both Austenite and Martensitic steels. Properties like hardness and toughness are very high for duplex grades and are difficult-to-machine. In this study, machining performance of Duplex Stainless Steel (DSS 2205) and Super Duplex Stainless Steel (SDSS 2507) was estimated during CNC dry milling operation. Cutting parameters namely feed rate, spindle speed and depth of cut were considered for this investigation and were optimized by considering surface roughness, cutting force and cutting temperature during CNC milling using Taguchi technique. Results revealed that depth of cut has more effect on cutting force than spindle speed and feed rate. Surface roughness was highly influenced by feed rate than spindle speed and least influenced by depth of cut for both the materials. Results also showed that, cutting temperature is mainly influenced by spindle speed. Optimum value for all the responses was obtained at spindle speed of 4200 rpm, feed rate of 50 mm/min and depth of cut of 0.35 mm for both DSS 2205 and SDSS 2507.
Island-Matrix Inhomogeneous Deformation Behavior, Formation of Deformation Band, and BUT Forming of DP Steel
Authors: Rana Amit Kumar , Dey Partha Pratim
Published: March 2022

Islands-Matrix-Dual-phase (I-M-DP) steel is received a great deal attention for better concern with the emissivity, fuel consumption and passengers safety. A number of deformation plasticity issues are yet to be fully understood. Complex deformation stages for various stain is predicted as the natural outfall of the plastic strain localization caused by the ill-assorted deformation between the martensite-island phase and the ferritic-matrix phase. Modeling is carried out both in macro level by bending under tension (BUT) for different roller radius/sheet thickness ratios to acquire strain and stress state deformation and micro scale by Representative Volume Element (RVE) according to element position. It can relate both the 2D, 3D micro and macro scale finite element based BUT model’s result of flow behavior. Systematically strain based severe deformation pattern arises from outfall of plastic strain localization and von Mises stress distribution in island-matrix steels are investigated on the microstructure by finite element method for ill-assorted deformation between phases.
What makes employees retain? Employee career planning vs employer career development in star-grade hotels in Colombo, Sri Lanka
Authors: Dassanayake D.M.C. , Kularathne H.M.R.D.
Published: March 2022

Developing and retaining a competent and professional workforce is of utmost importance in service-oriented firms, and it is even more crucial in the hotel industry as the entire industry relies on treating and caring for guests for their maximum comfort. Perfect career management practices can significantly aid employee retention. This study examined the career management prospects of front-line hotel workers from two different viewpoints; employee career planning and employer career management. Data was collected through a structured questionnaire from a randomly selected sample size of 150 from star grade hotels in Colombo. Hierarchical PLS-SEM analysis revealed that employer career management initiatives are more important than employee career planning behaviours in hotel employee retention. Employee willingness to participate in development activities and manager support were the main factors in employee retention. The two hierarchical constructs of employee career planning and employer career management were also developed based on six conceptions commonly cited in the literature as one of the major contributions of this research to the theories.
Prevalence and correlated factors for chronic total occlusion in patients with coronary artery disease in Iraqi Kurdistan
Authors: Abdulah Deldar Morad , Miro Shawkat Salih
Published: March 2022

Patients with significant coronary artery disease often have at least one vessel with Chronic Total Occlusion (CTO) as demonstrated by coronary angiography. However, the prevalence and determinants of CTO differ according to ethnicity. We aimed to investigate the prevalence and determinants of CTO in the Iraqi Kurdistan population in 2015. Clinical and angiographic data were collected in consecutive patients that underwent coronary angiography at our institution between January and December 2015. Coronary artery disease (CAD) was determined as 50% diameter stenosis in one coronary artery and CTO as total coronary artery occlusion of 3-month duration. Among 260 patients diagnosed with ischemic coronary artery disease and undergone coronary angiography, 28.5% (n=74) were diagnosed to have at least one CTO vessel and 69 (26.5%) patients had a previous history of myocardial infarction. CTOs were located in the left anterior descending coronary artery in 45% of patients while in the right coronary artery in 32%. CTO patients were substantially older (61 vs 56 years; p <0.0001) and more likely to live in non-urban areas. They frequently had more hypertension, dyslipidemia, diabetes mellitus, previous myocardial revascularization, being an exsmoker, and renal dysfunction as compared to patients without CTOs. At univariate analysis, a previous history of coronary artery bypass graft (CABG) surgery was the only predictor of having a diagnosis of CTO. Patients diagnosed with CTO in Iraqi Kurdistan had several comorbidities including cardiovascular risk factors and renal dysfunction. Previous CABG was the only predictor of CTO diagnosis.
Fast optimization via inertial dynamics with closed-loop damping
Authors: Attouch Hedy , Boţ Radu Ioan , Csetnek Ernö Robert
Published: March 2022

In a real Hilbert space

\mathcal{H}

, in order to develop fast optimization methods, we analyze the asymptotic behavior, as time

t

tends to infinity, of a large class of autonomous dissipative inertial continuous dynamics. The function

f: \mathcal{H} \to \mathbb{R}

to be minimized (not necessarily convex) enters the dynamic via its gradient, which is assumed to be Lipschitz continuous on bounded subsets of

\mathcal{H}

. This results in autonomous dynamical systems with nonlinear damping and nonlinear driving force. We first consider the case where the damping term

\partial \phi (\dot{x}(t))

acts as closed-loop control of the velocity. The damping potential

\phi : \mathcal{H} \to \mathbb{R}_+

is a convex continuous function which reaches its minimum at the origin. We show the existence and uniqueness of a global solution to the associated Cauchy problem. We analyze the asymptotic convergence and the convergence rates of the trajectories generated by this system. To do this, we use techniques from optimization, control theory, and PDEs: Lyapunov analysis based on the decreasing property of an energy-like function, quasi-gradient and Kurdyka–Łojasiewicz theory, and monotone operator theory for wave-like equations. Convergence rates are obtained based on the geometric properties of the data

f

and

\phi

. We put forward minimal hypotheses on the damping potential

\phi

guaranteeing the convergence of trajectories, thus showing the dividing line between strong and weak damping. When

f

is strongly convex, we give general conditions on the damping potential

\phi

which provide exponential convergence rates. Then, we extend the results to the case where additional Hessian-driven damping enters the dynamic, which reduces the oscillations. Finally, we consider a new inertial system where damping jointly involves the velocity

\dot{x}(t)

and the gradient

\nabla f(x(t))

. This study naturally leads to similar results for proximal-gradient algorithms obtained by temporal discretization; some of them are studied in the article. In addition to its original results, this work surveys numerous works devoted to the interaction between damped inertial continuous dynamics and numerical optimization algorithms, with an emphasis on autonomous systems, adaptive procedures, and convergence rates.

The Urucum Massif (UM) is recognized as a region of flora and fauna endemism, and it is one of the few mountain ranges found in the western edge of the Brazilian Pantanal, in Mato Grosso do Sul state. Despite the lack of knowledge on mammalian species occurrence, several mining companies established in this region has rapidly changed its landscape. Therefore, this study aims to carry out an inventory of medium- to large-sized mammals in the UM to estimate their relative abundance and activity patterns using data provided by camera trapping surveys. Two main camera-trapping surveys were carried between October 2014 and July 2015, in addition to a small survey in July 2016. Results showed 25 species from medium- to large-sized mammals. Dicotyles tajacu, Dasyprocta azarae and Dasypus novemcinctus presented the highest relative abundance indices. Overall, D. azarae, Nasua nasua and Euphractus sexcinctus were diurnal, while Tamandua tetradactyla, D. novemcinctus, Tapirus terrestris and Sylvilagus paraguensis were nocturnal, in turn, D. tajacu and Cerdocyon thous were associated with the crepuscular period. Overall, 28 % (N = 7) and 12 % (N = 3) of the recorded species are threatened nationally and globally, respectively. Due to the scarcity of protected areas in the UM, we recommend long term monitoring of mammals and ecological studies to support conservation actions for this group in the region

Published: March 2022

Although the importance of Total Quality Management (TQM) practices in improving hotel service performance is well known since it is a key to achieving service excellence, the role of TQM practices in improving service recovery performance through service innovation in service businesses has remained a relatively untapped research field. Thus, the purpose of the current study is to investigate the impacts of TQM practices on service recovery, as well as the mediating role of service innovation between TQM and service recovery. This study used a quantitative survey method, with data collected from a sample of 414 staff working at Jordan's five-star hotels using a questionnaire. The results indicated a significant positive effect of TQM on service innovation and service recovery, and that service innovation fully mediates the relationship between TQM and service recovery. The current study presents an innovative approach since it is one of the first and few research papers that provide empirical evidence for the mediating effect of service innovation between TQM and service recovery. This study contributes to the existing literature by examining the roles of TQM and service innovation in increasing service recovery performance, and it helps practitioners understand how TQM practices support service innovation and the latter’s role in improving service recovery performance.

Published: March 2022

We evaluate the asymmetric impact of the second wave of COVID-19 on the spot electricity price in India. The estimated nonlinear autoregressive distributed lag model shows that both positive and negative shocks from the COVID-19 pandemic reduce the long-run spot electricity price. Surprisingly, the COVID-19 negative shock outweighs its positive shock. This result shows the detrimental effect of the COVID-19 pandemic on the spot electricity price, which policymakers in India should not overlook.

We estimate the average energy demand and supply for the Indian states using data from March 23 to September 24, 2020. Our results indicate that transmission and distribution losses were much lower during the initial weeks of lockdown, but increased significantly thereafter. The market-clearing prices and volumes are lower than for the H1N1 influenza pandemic period, negatively impacting investor sentiment. Therefore, energy policies must focus on demand-side measures, apart from liquidity flow.

This paper designs a nonlinear PI-type controller for the robust control of a boost DC-DC converter using a particle swarm optimization (PSO) algorithm for increasing the output voltage of the photovoltaic (PV) system. In addition, the PI controller is used to tracking the maximum power from the PV panel, at different atmospheric condition. For tuning PI controllers is a tedious work and it is difficult to tune the PI gains optimally due to the nonlinearity. This paper presents an approach to use the particle swarm optimization algorithm to design the optimal PI controllers. The Simulations results show that the proposed controller exhibits better behavior in terms of settling time and overshoot and better performance of the converter.

The paper analyzes the legal activity and based on the research, predictions are made on the development and change of the way of providing services through the process of harmonization of the rights of the Republic of Serbia and the system of the European Union. The author starts from the definition of the concept of advocacy as an activity. Through historical development, the importance of the legal profession within the legal system of a country and the role of this activity in society at large is pointed out. Comparative analysis leads to certain general determinants that are common to legal systems. After that, with the focus on the study of general legal acts in the Republic of Serbia, the key documents towards a positive legal definition are analyzed. As a positive legal determination experiences its control of reality through the practical application of what is prescribed, so through the decisions of key subjects, it is positively legally put to the test. Considering that there is a need for corrections in the field of regulation in the Republic of Serbia, the author presents proposals as a form of initial discussion on this occasion. By presenting bold proposals, the author aims at the type of initial hypotheses that should arouse the interest of key actors, which in some way touches on this topic crucially, and indirectly the entire social community. The author also strives to set out through a pragmatic analysis, what would be the aspirations for the best legal rule and positively legally and practically regulate the area of providing the services of a lawyer.

En este trabajo se presenta la aplicabilidad de una herramienta computacional para diseño de concentradores solares de canal parabólico con sistema de generación directa de vapor. El diseño se aplica para la Ciudad de México, evaluando 12 valores de irradiancia solar (W⁄m^2 ), obtenidos de la estación meteorológica de la Universidad Autónoma Metropolitana, Xochimilco. El diseño del concentrador se basa en el diámetro externo del tubo absorbedor, para obtener los datos geométricos: apertura de la parábola (m), longitud focal (m), longitud total (m) y los diámetros interno y externo del tubo transparente (m). El flujo másico (kg⁄s) es el principal parámetro para obtener las características térmicas, el software muestra como resultados en forma de tablas el flujo de calor útil (W), flujo de calor perdido (W), eficiencia térmica (%) y las temperaturas de los tubos absorbedor y  transparente (℃) respectivamente. El tubo absorbedor del concentrador completo, se divide en tres secciones, precalentamiento, donde el agua ingresa a la temperatura inicial (cercana o igual a la temperatura ambiente) y llega al estado de líquido saturado, en la siguiente sección se lleva a cabo la evaporación, todo el fluido de trabajo cambia de fase, desde el estado de líquido saturado hasta llegar al estado de vapor saturado, manteniendo la temperatura constante y, por último, el proceso de sobrecalentamiento, iniciando en el estado de vapor saturado, hasta llegar a la temperatura final deseada, impuesta por el usuario.

Cyberbiosecurity has emerged as a new field combining cybersecurity and biosecurity. The convergence of cybersecurity and biosecurity can potentially impact the digital operations of enterprises in a variety of industries, including agriculture, manufacturing, and healthcare. This systematic review summarizes and synthesizes research on the increasing importance of cyber-biosecurity threats and the importance of cyber-biosecurity measures in combating the misuse of cyberspace and bioscience technology. The author performed three distinct searches through ProQuest, Web of Science, and MEDLINE databases. The author used keywords to identify 15 articles that met the systematic review’s purpose. Analysis of the 15 articles revealed that the intersection of current advancements in biosciences with conventional cyberspace security risks has promoted the awareness and discovery of threats in the cyberbiosecurity field. The author concludes that cybersecurity is the foremost biological weapon to the digital world when challenged by new technologies and security threats. As a result, cyberbiosecurity measures must safeguard the bioeconomy and address the possibility for or actual misuse of critical information, materials, and systems at the convergence of biosciences and cyberspace. Stakeholders interested in cyberbiosecurity outcomes need to be competent in its implementation.

Authors: Mohammad Saddam Atteyia
Published: March 2022

This work explore the boundary layer behavior under the effects of Soret and Dufour on the mixed convection adjacent to inverted cone immersed within non-Darcian porous milieu together with chemical reaction action. The natural and forced convection limits are also considered in this study. The equations governing the problem together with the boundary conditions are converted to non-similar non-dimensional shape and solved numerically using finite difference method. It was found that enhances the value of the Soret number will increase the amount of heat transport and decrease the amount of mass transport. Enhances the value of Dufour number or chemical reaction parameter will reduce the amount of heat transfer and raise the amount of mass transfer.

Jatropha curcas has been identified as an alternate source for biofuel, and thus requires immediate establishment of plantations in areas not utilized for food production such as in mine tailings sites. Screenhouse experiments were conducted to determine the survival, growth and copper (Cu) accumulation of non-mycorrhizal or mycorrhizal J. curcas seedlings or cuttings grown in oven sterilized grassland soil from Caliraya, Laguna and in mine tailing soils from Paracale, Camarines Norte and Mogpog, Marinduque. Grassland soil was sterilized in an oven for three days at 100˚C prior to use. Seedlings or cuttings were either uninoculated or inoculated with Mykovam or MineVAM mycorrhizal inoculants. Results show that Paracale soil supported the highest survival and best growth of seedlings or cuttings. In Mogpog soil, all seedlings died before two months except those inoculated with Mykovam while all cuttings died on the third month. Non-mycorrhizal seedlings did not survive in Caliraya soil while mycorrhizal inoculation increased seedling survival and growth. Cuttings did not respond to inoculation, probably due to low mycorrhizal infection (≤14 %) as compared to seedlings (≤100 %). Mykovam promoted higher survival and better plant growth than MineVAM because of its higher root colonization. Cu accumulation was higher in the roots of mycorrhizal plants and the lowest was in the leaves especially in the Mykovam-inoculated plants. In conclusion, Mykovam inoculated J. curcas grew better with higher survival rate than the control thus this imply that rehabilitation of grasslands in Caliraya, Laguna and mine tailing areas in Paracale, Camarines Norte can be done for its potential for biofuel production. However, field trials should be conducted.
