Published: June 2019

This study aims to present the ABET-CAC accreditation framework and discusses how to manage program’s constituencies of an academic program in higher education. It describes the program’s associated entities and the methods of creating required evidence for the program accreditation in computer science education. It follows a mixed method to evaluate and measure the program performance. It discusses the program’s performance measurement methods and its analysis. It emphasizes the program’s entities such as students learning outcomes, course assessment and performance evaluation. It shows a scientific approach that measures the program’s performance. It suggests the evidence should be considered as important indicators for both when planning the quality improvement for the program delivery and program’s benchmarking. For any program accreditation in computing education, the framework needs to be followed at least for two years to ease the program’s review process. This will help prepare competently for the accreditation, ahead of program’s review visit by the commission.
Understanding Language MOOC Learners: The Issue of Capability Development
Authors: Agonács Nikoletta , Matos João Filipe
Published: June 2019

Having a clear understanding of the learner population has an impact on effective course design and delivery in any learning context. However, it has greater importance in a MOOC learning environment because of the high diversity of participants. Most of the review studies on MOOC research mention learner population as a recurrent theme. These studies focus on behaviours, performance, learner participation and interaction patterns, learner perceptions and preferences, learner experiences, motivation, demographics, and classifications of learners into subpopulations. Nevertheless, there is little knowledge about the learners’ perceptions of their own learning and the learning process, which is a key element of learning according to heutagogy, the theory of self-determined learning. In our study, which is based on two theoretical pillars (heutagogy and the Common European Framework of Reference for Languages: Learning, Teaching, Assessment) we aimed at capturing traces of capability development through language MOOC learners’ reflections and identifying learning activities that are perceived by learners as preferred activities for skill acquisition in a language MOOC learning environment. We designed two open-ended questions in a survey format that were administered in an Italian language MOOC offered by Wellesley College. We were able to capture traces of capability development through learners’ reflections, and we also found that a) based on learners’ perceptions the most preferred way of acquiring new skills is through receptive activity types; b) these activity types coincide with learners’ perceptions of their own understanding (listening and reading) skill development.
Performance and Cost Analysis of Lithium-Ion Battery for Powering Off-Grid Telecoms Base Stations in Africa
Authors: Luta Doudou Nanitamo , Raji Atanda K.
Published: June 2019

Most African remote telecoms base stations are powered from diesel generators, however, these generators are losing attractiveness due to their less reliability in addition to high operational and maintenance costs. Over 65% of the loss of telecom services observed in remote areas are caused by outages resulting from diverse types of failures that these generators can suffer, on top of their impacts on the environment. As alternative, off-grid renewable energy systems are often employed in place of diesel generators due to their capability to provide reliable electricity at an acceptable cost. This study proposes an off-grid system based on PV generators and backup energy storage consisting of lithium-ion batteries as an extended solution for powering remote telecom base stations in Africa. Modelling and simulation is performed using Matlab/Simulink environment. The findings showed better characteristics of lithium-ion battery bank as compared to lead-acid unit; lithium-ion battery bank displayed higher initial current and voltage over lead-acid battery bank. Moreover, when, both battery banks reached 50 % of their state of charge, lithium-ion bank current was still higher than that of lead-acid bank. In the same vein, lithium-ion battery bank presented a slower discharge time than lead-acid battery bank on top higher values at 50 % and 70% state of charges. Lastly, the state of charge of the lead-acid battery at the end of the simulation was 50 %, while that of the lithium-ion battery bank was around 60 %.

Published: June 2019

In the present condition, customer demand has increased gradually due to technological development and globalisation in this world. So this made the industrialist to deliver the products at right quantity at right place at right time with shorter lead time. But due to high rejection rate the industries fails to meet the customer demand which in turn reduces the customer satisfaction. Hence, this research an attempt was made to reduce the defects of casting components in an original equipment manufacturer. The study was carried out in a foundry of brake drum manufacturing industry. The problem was inside that the industry could not meet the customer demand due to high rejection rate and the major contributor for high rejection is found to be sand drop. Hence, proposed solutions have been implemented to achieve the objectives. After implementation of proper lean tools it was observed from the results that, the rejection rate was reduced by about 4% and the quality level was increased by about 4.4%.

Applications including energy generation and infrastructure, electric and hybrid vehicles, electric vehicle charging, datacenters, industrial automation, smart cities and buildings, home appliances, and transportation are driving demand for power devices. While many companies continue to expand production of silicon-based power devices, there is also demand for devices based on new wide band gap (WBG) materials such as silicon carbide (SiC) and gallium nitride (GaN). Driven by the need for increased power density and system efficiency, these WBG materials are being adopted in many applications and may require new packages, materials, and assembly methods. This presentation describes package trends and discusses some of the challenges faced.
Power Module Packaging: Market and Technology Trends
Authors: Barbarini Elena , Troadec Claire
Published: June 2019

In recent years, several new power module designs have emerged, principally driven by the severely challenging requirements for high power density and integration from the automotive industry. Indeed, electric and hybrid cars are the best example of technology innovation in the design of power modules. The Toyota Prius' fourth generation double-sided cooling power modules might be the most well-known example. Yet today many other module manufacturers are also proposing new designs that move away from conventional power module layers and technologies. In our presentation, we will start with market trends and illustrate how industrial applications still remain the biggest part of the power module market. We will then demonstrate that the automotive industry is leading in technological innovations in packaging, helping and accelerating the implementation of these new technologies thanks to high manufacturing volumes. We will detail these technology trends by providing real teardown and cost analysis of various power modules. We will explain how they are creating opportunities for some material suppliers, and at the same time, are transforming today's businesses for power packaging.

Published: June 2019

While there are a number of different polymer cure processes, the specific process has a significant effect on the quality and performance of cured polymers, applicable to FOWLP Multi-level Metallization Process. The measurement for variations of noise immunity, dielectric strength and other dielectric properties in the most common baked polymers used for FOWLP manufacturing are still a huge challenge in the back-end industry. In this paper, the measurement of cured-film composition and dielectric properties were studied for different types of Polyimide and PBO materials as a function of different cure process parameters.

Comparisons of the amount of outgassing at metallization under different process conditions supported the theory of vacuum bake as a more complete cure process. The paper reports the comparison of trapped gases, as well as amount of outgassing, as a function of levels of vacuum bake, time and temperature of the bake. The films cured under different conditions were studied using different characterization methods such as FTIR, RGA, etc. In conclusion, the importance of the cure process is presented with respect to multi-level metallization, low noise immunity and low to zero outgassing for current FOWLP.
Material Design Advancement Create Multifunctional Materials for Single-Layer Bonding and Debonding
Authors: Prenger Luke , Liu Xiao , Wu Qi , Puligadda Rama
Published: June 2019

Multifunctional materials are a relatively new topic in the semiconductor industry for wafer-level packaging (WLP). With the increase in processing steps and the emergence of more advanced technologies, the use of multifunctional materials will become a more integral part in the future of temporary bonding and debonding (TB/DB) as well as other advanced packaging applications. One approach to multifunctional material design incorporates adhesive and laser release attributes in one material layer. Although this is similar to a thermal release material, it has greater thermal capabilities due to its ability to be cured and undergo laser debond. Many advantages may be obtained by combining a curable adhesive and laser release layer into one material. One of the greatest advantages is the reduction in overall processing time and steps required to bond wafer pairs as well as the reduction of chemical waste, due to the use of one material compared to two or more materials which significantly reduces the cost of ownership. Curable adhesive single layer systems offer access to higher temperatures with less material flow from the curable layer, strong adhesion for high stress applications where wafers can delaminate or spontaneously debond when using multilayer mechanically debonding systems such as Fan-Out Wafer Level Packaging (FOWLP), and offer lower wafer stress and warpage due to fewer material interfaces within the bonded wafer pairs causing less potential mismatch of materials coefficient of thermal expansion(CTE). Some challenges with this concept stem from the concern of the cleanability of a curable layer and potential laser damage to the device. In order to wet clean a curable layer, which is usually very solvent resistant due to the crosslinked nature, requires harsh solvent based solutions (that may contain either strong acid or base, require long cleaning time, and high temperature).

This study will address all of the aforementioned challenges and includes the developmental advancements in material designs that resulted in the creation of new multifunctional materials. These multifunctional materials have been designed to be thermally curable, prevent material reflow of the bonding layer at higher temperatures, while still remaining wet cleanable without the use of harsh chemicals and long times. As with any material that utilize laser release methods there are concerns about device damage from laser energy penetrating to the device but multifunctional materials address this in two ways: they offer high absorbance of the laser energy at all commercially available laser tool wavelengths and they can be utilized as a thicker film as they act as the bonding layer as well. By overcoming their challenges, they will minimize the cost of ownership while driving advancement in future materials and processing.
Biogenic isoprenoid emissions under drought stress: Different responses for isoprene and terpenes
Authors: Bonn Boris , Magh Ruth-Kristina , Rombach Joseph , Kreuzwieser Jürgen
Published: June 2019

Abstract. Emissions of volatile organic compounds (VOCs) by biogenic sources depend on different environmental conditions. Besides temperature and photosynthetic active radiation (PAR), the available soil water can be a major factor, controlling the emission flux. This factor is expected to become more important under future climate conditions including prolonged drying-wetting cycles. In this paper we use results of available studies on different tree types to set up a parameterization describing the influence of soil water availability (SWA) on different isoprenoid emission rates. Investigating SWA effects on isoprene (C5H8), mono- (C10H16) and sesquiterpene (C15H24) emissions separately, it is obvious that different plant processes seem to control the individual emission fluxes providing a measure of plants to react on stresses and to interact. The SWA impact on isoprene emissions is well described by a biological growth type curve, while the sum of monoterpenes displays a hydraulic conductivity pattern reflecting the plants stomata opening. However, emissions of individual monoterpene structures behave differently to the total sum, i.e. the emissions of some increase whereas of others decline at decreasing SWA. In addition to a rather similar behaviour as of monoterpene emissions, total sesquiterpene fluxes of species adapted to drought stress tend to reveal a rise close to the wilting point protecting against oxidative damages. Considering further VOCs too, the total sum of VOCs tends to increase at the start of severe drought conditions until resources decline. On the contrary, OH and ozone reactivity enhance. Based on these observations a set of plant protection mechanism displays for drought stress and implies notable feedbacks on atmospheric processes such as ozone, aerosol particles and cloud properties. With progressing length of drought periods declining storage pools and plant structure effects yield different emission mixtures and strengths. This drought feedback effect is definitely worth consideration in climate feedback descriptions and for accurate climate predictions.
Computing water flow through complex landscapes, Part 2: Finding hierarchies in depressions and morphological segmentations
Authors: Barnes Richard , Callaghan Kerry L. , Wickert Andrew D.
Published: June 2019

Abstract. Depressions – inwardly-draining regions of digital elevation models – present difficulties for terrain analysis and hydrological modeling. Analogous depressions also arise in image processing and morphological segmentation where they may represent noise, features of interest, or both. Here we provide a new data structure – the depression hierarchy – that captures the full topologic and topographic complexity of depressions in a region. We treat depressions as networks, in a way that is analogous to surface-water flow paths, in which individual sub-depressions merge together to form meta-depressions in a process that continues until they begin to drain externally. The hierarchy can be used to selectively fill or breach depressions, or to accelerate dynamic models of hydrological flow. Complete, well-commented, open-source code and correctness tests are available on Github and Zenodo.
Miocene basement exhumation in the Central Alps recorded
by detrital garnet geochemistry in foreland basin deposits
Authors: Stutenbecker Laura , Tollan Peter M. E. , Madella Andrea , Lanari Pierre
Published: June 2019

Abstract. The Neogene evolution of the European Alps was characterized by the exhumation of crystalline basement, the so-called external crystalline massifs. Their exhumation presumably controlled the evolution of relief, distribution of drainage networks and generation of sediment in the Central Alps. However, due to the absence of suitable proxies, the timing of their surficial exposure, and thus the initiation of sediment supply from these areas, are poorly constrained. The northern alpine foreland basin preserves the Oligocene to Miocene sedimentary record of tectonic and climatic adjustments in the hinterland. This contribution analyses the provenance of 25 to 14 My-old alluvial fan deposits by means of detrital garnet chemistry. Unusually grossular- and spessartine-rich garnets are found to be unique proxies for identifying detritus from the external crystalline massifs. In the foreland basin, these garnets are abundant in 14 My-old deposits, thus providing a minimum age for the surficial exposure of the crystalline basement.

Published: June 2019

Archaeological and geophysical prospection of the site of Khirbat al-Sar/Sara in Jordan, carried out by a team from the Polish Centre of the Mediterranean Archaeology (PCMA), University of Warsaw, has resulted in a comprehensive plan mapping all visible architectural remains. A Roman-period sacred compound appears to be a central feature of this site. Pottery collected from the surface has given a time range for the settlement from the late Iron Age through the Mamluk period. The electrical resistivity method using probe arrays that allowed ground penetration to a maximum depth of approximately 1.50 m revealed meaningful information on the spatial organization of the site. Numerous high-resistance anomalies were interpreted as a reflection of building remains.

The article collects the modest evidence available on the use (and possible production) of ceramic building material by the
Roman army in Colchis, using it as a backdrop for presenting the exceptional richness, in quantity as much as diversity, of the finds from Gonio/Apsaros. The signatures on these products add to the value of this assemblage. Part 1 of the article presents documented examples of stamps on bricks, roof tiles and ceramic pipes from the Gonio/Apsaros fort and links them to the construction projects of specific Roman army units in the Cappadocia province. The results of laboratory tests conducted on samples of ceramic products and raw clay from Gonio, presented in Part 2, distinguish between two reference groups for the production of which clay from near the fort was used. However, it has not been possible to indicate the specific deposits of such raw material used by the Roman army.

Published: June 2019

Human factor is one of more important resources of the organization, reflecting status quo of its intangible assets. Skilful managing these components increases entity’s potential in the long run. So-called key performance factors (KPIs) can be regarded as a starting point for its measurement. Reviewing “work factor” in an enterprise helps “capturing” areas of low productivity, improving tasks implementation, appropriate employees motivating, making efforts for continuous development. KPIs are grouped within the framework of four perspectives referring: internal processes, client, learning and owner. This study sets out to assess achievements of individual divisions of a service company in each of these areas, by using properly designed indicators. The main thesis of the publication maintains that the statistic range based on arithmetic means of branch performance ratios allows to determine the size of the competence gap of a given revenue center.

Published: June 2019

From a dynamic learning perspective, the development of comprehensive entrepreneurship takes into account that entrepreneurs learn during the creation and management of their enterprises. This study aims to analyze the dimension of entrepreneurial learning of entrepreneurs of micro and small-size companies that had business failure and have created new businesses. The methodology consists in a qualitative and exploratory study, with cross-section approach and longitudinal perspective. Three entrepreneurs were selected to participate in the study based on convenience and availability. Data were collected through interview in depth, using a standard protocol. Content analysis was used having the narrative as a basis for the research. The results showed that all entrepreneurs, at the time that they had business failure, presented an immediate and spontaneous reflexive action because they did not remain inactive when facing the challenges that had led them to stop theirs activities. In consideration of the dimension of entrepreneurial learning, we suggest that the acquisition of knowledge related to the overcoming of adversities and obstacles is able to stimulate and enable entrepreneurs to create a new venture.

Background: Treatment options are limited for patients with advanced hepatocellular carcinoma (HCC) that progresses after treatment with sorafenib. Cabozantinib, an oral small molecule inhibitor of multiple tyrosine kinase receptors, recently showed improved overall survival (OS) compared with placebo in sorafenib-pretreated patients with advanced HCC in the CELESTIAL trial. This study assessed the cost-effectiveness of cabozantinib for second-line treatment of patients with advanced HCC from a US healthcare system perspective. Patients and Methods: Cost and utility data were extracted from the CELESTIAL trial and used to determine the cost-effectiveness of cabozantinib compared with placebo plus best supportive care. The main outcome of this study was the incremental cost-effectiveness ratio (ICER), expressed as cost per quality-adjusted life year (QALY) gained by using cabozantinib compared with placebo plus best supportive care in sorafenib-pretreated HCC. Results: In the base-case analysis using data from the CELESTIAL trial, the incremental QALY and ICER were 0.067 and $1,040,675 for cabozantinib compared with placebo and best supportive care. OS reported in the CELESTIAL trial (hazard ratio, 0.76; 95% CI, 0.63–0.92) had the strongest association with the ICER. In one-way sensitivity analyses, there were no scenarios in which cabozantinib was cost-effective. In a cost-threshold analysis, cabozantinib would have to be priced at least $50 per pill to be cost-effective considering a willingness to pay of $100,000 per QALY. Although the CELESTIAL trial demonstrated that cabozantinib improves OS compared with placebo in patients with HCC that progresses after treatment with sorafenib, our analysis shows that cabozantinib is not a cost-effective therapy in this scenario. Conclusions: At current costs, cabozantinib is not cost-effective for second-line therapy of HCC in the United States.

Background: Overwhelming randomized controlled trial evidence demonstrates that exercise has positive health impacts during and after treatment for breast cancer. Yet, evidence generated by studies in which exercise programs are delivered outside a tightly controlled randomized trial setting is limited. The purpose of this study was to assess the effectiveness of an evidence-based exercise program with real-world implementation on physical fitness and quality of life (QoL). Patients and Methods: Oncologists referred women with early-stage breast cancer who were scheduled to receive adjuvant chemotherapy. The program consisted of supervised aerobic and resistance exercise of moderate to vigorous intensity 3 times per week until the end of treatment (chemotherapy ± radiotherapy), then twice per week for 10 weeks, followed by once per week for 10 weeks. Health-related physical fitness and QoL were assessed at baseline, end of treatment, end of program, and 1-year follow-up. Results: A total of 73 women were enrolled. Estimated peak VO2 (VO2peak), QoL, and body weight were maintained between baseline and end of treatment, whereas muscular strength improved (P<.01). By the end of the program, VO2peak, heart rate recovery, waist circumference, and some aspects of QoL were improved (all P<.01) relative to baseline. One year later, VO2peak, QoL, and waist circumference were maintained relative to end of program, whereas the improvements in strength and heart rate recovery had dissipated (all P<.01). Conclusions: Evidence-based exercise programming delivered with real-world implementation maintained VO2peak, strength, and QoL during adjuvant treatment and improved these measures after treatment completion among women with breast cancer. Continued guidance and support may be required for long-term maintenance of strength improvements in this population.

O estudo analisou os fatores de riscos de incêndios em um mercado popular conhecido como ‘Camelódromo’ em funcionamento no centro da cidade de Crato/Ceará, com o objetivo de servir como suporte para composição de uma equipe de brigada de incêndio eficiente para atuar na prevenção e combate a eventuais ocorrências de sinistros. Foram utilizados diversos procedimentos metodológicos tendo como base as exigências contidas na legislação nacional de proteção contra incêndios e em particular do Estado do Ceará, com destaque para as entrevistas, inspeções no local com registros fotográficos e levantamento documental. Após realizada a análise ficou constatado a enorme deficiência em relação à prevenção e controle dos riscos de incêndios nesse espaço público. A falta de equipes de brigadistas voluntários ou não entre os concessionários do ‘Camelódromo’ do Crato potencializa o poder catastrófico de possíveis ocorrências de sinistros, o que corrobora a necessidade urgente de implantar uma equipe de brigada de incêndio nesses locais.

Comparison Between Reactive and Proactive Protocols of Wireless Sensor Networks: Railway Application
Authors: Del-Valle-Soto Carolina , Valdivia Leonardo Jesus , Velázquez Ramiro
Published: June 2019

Railway is a critical application; hence, all systems that compose the railway infrastructure must meet two conditions: availability and safety. The availability ensures continuous operation of the system; on the other hand, safety is achieved when the device works properly regardless of the environmental or operating conditions. In addition, Wireless Sensor Networks (WSN) are used to perform tasks previously performed manually. However, it is necessary to analyse what protocol is appropriate for the railway industry, since availability and safety are the required attributes. In this work, a recently proposed routing protocol, the Multi-Parent Hierarchical (MPH), has been compared with a well-known protocol, the Ad-hoc On-Demand Distance Vector (AODV), in order to find the most suitable one for the railway applications. For this purpose, a simulator has been developed, which faithfully reifies the workings of a given protocol, considering a fixed, reconfigurable ad-hoc network given by the number and location of participants, and general network conditions.
The dilemma of teaching with digital technologies in developing countries: Experiences of art and design teacher educators in Uganda

This case study explores how teacher educators use digital technologies in teaching Art and Design (A&D) in a developing country. It uses semi-structured interviews and non-participant observations to gather qualitative data from teacher educators at two teacher training institutions in central Uganda. To understand the actual use of technologies by teacher educators in the A&D classroom, analysis of the data employed concepts from van Dijk’s resources and appropriation theory (RAT) and Mishra and Koehler’s TPACK framework. The findings indicate that low digital competence among teacher educators and insufficient access to appropriate hardware, software and the Internet means that A&D teacher educators in Uganda only occasionally use digital technologies in the classroom. Instead, teacher educators use non-professional software such as Microsoft Office to teach Art and Design subjects. The findings further confirm teacher educators’ limited awareness of the relationship between technology, pedagogy and content knowledge in the Art and Design classroom. Insufficient access to adequate digital resources, skills and knowledge explains the low creative use of digital technologies in teaching A&D lessons.
