Full textAbstract:
Currently, the most commonly created formal languages are configuration languages. So far source code annotations and XML are the leading notations for configuration languages. In this paper, we analyse the correspondence between these two formats. We show that there are typical XML to annotations mapping solutions (mapping patterns) that indicate a correspondence between embedded and external metadata formats in general. We argue that mapping patterns facilitate creating configuration tools and we use a case study to show how they can be used to devise a mapping between these two notations.

Abstract Patient portals are popular health care tools. Few portals target caregiving families and few use predictive modeling to assist caregiving families make decisions about elder care options. Our goal is to incorporate the algorithms being developed for predicting tipping points in elder care to assist caregiving families visualize changes in older adults’ activity patterns, understand possible implications for continued in-home safety, and access educational information and consultation. While many patients use portals, use is restricted among persons in racial and ethnic minorities, with lower educational levels and poorer health literacy, and with fewer economic resources. The following strategies help us address these issues. Our portal archives data from affordable, wearable technology. Portal access uses similarly technology. Our educational materials use techniques known to be appealing and effective with older individuals in unique groups, e.g., results displays; fotonovelas. Input from community members/users helps maintain sensitivity to cultural appropriateness and health literacy.

We propose a pattern-based approach to evaluating data visualization: a set of general and reusable solutions to commonly occurring problems in evaluating visualization tools, techniques, and systems. Patterns have had significant impact in a wide array of disciplines, particularly software engineering, and we believe that they provide a powerful lens for characterizing visualization evaluation practices by offering practical, tried-and-tested tips, and tricks that can be adopted immediately. The 20 patterns presented here have also been added to a freely editable Wiki repository. The motivation for creating this evaluation pattern language is to (a) capture and formalize “dark” practices for visualization evaluation not currently recorded in the literature, (b) disseminate these hard-won experiences to researchers and practitioners alike, (c) provide a standardized vocabulary for designing visualization evaluation, and (d) invite the community to add new evaluation patterns to a growing repository of patterns.

Full textAbstract:
The paper focused on a topic related to the possibilities of using wavelet analysis to evaluate the changes in the geometrical structures of the surfaces arising during the honing process with whetstones with variable granularity. The cylinder liners of the combustion engine are machined elements. The basics of the wavelet analysis and the differences between filtering with standardized filters (e.g., Gauss filter), Fourier analysis, and the analysis of the results obtained when measuring the surface roughness with other wavelets were described. Trials of honing four cylinder liners were carried out. Roughness measurements of 3D spatial structures of the prepared liners were made. The principle of selecting wavelets for roughness assessment of structures with cross-hatch pattern was described. Roughness structures generated on the honed surfaces of cylinder liners were assessed using Gaussian filtration and Morlet, Daubechies Db6, and Mexican hat wavelets. In order to demonstrate the differences generated when the Gaussian filtration and selected wavelets were used on surface structures, the surfaces obtained with the use of these filtering tools were subtracted from each other, which allowed obtaining information about the changes occurring on the assessed surfaces, which were generated after the use of various filtering tools. For the assessed surfaces, during the subtraction operation, the mean square error was calculated, informing about the degree of similarity of both compared surfaces. The result of the work carried out is the creation of basic recommendations for the selection of wavelets when assessing honed surfaces with different degrees of regularity of the traces generated on them.

 Studies have found serious games to be good tools for programming education. As an outcome from such research, several game solutions for learning computer programming have appeared. Most of these games are only used in the research field where only a few are published and made available for the public. There are however numerous examples of programming games in commercial stores that have reached a large audience.This article presents a systematic review of publicly available and popular programming games. It analyses which fundamental software development concepts, as defined by the ACM/IEEE Computer Science Curricula, are represented in these games and identifies game design patterns used to represent these concepts.This study shows that fundamental programming concepts and programming methods have a good representation in mainstream games. There is however a lack of games addressing data structures, algorithms and design. There is a strong domination of puzzle games. Only two of the 20 studied games belong to a different genre. The eleven game design patterns identified in this study have potential to contribute to future efforts in creating engaging serious games for programming education.

Full textAbstract:
Abstract. One of the major challenges in river restoration is to identify the natural fluvial landscape in catchments with a long history of river control. Intensive land use on valley floors often predates the earliest remote sensing: levees, dikes, dams, and other structures alter valley-floor morphology, river channels and flow regimes. Consequently, morphological patterns indicative of the fluvial landscape including multiple channels, extensive floodplains, wetlands, and fluvial-riparian and tributary-confluence dynamics can be obscured, and information to develop appropriate and cost effective river restoration strategies can be unavailable. This is the case in the Pas River catchment in northern Spain (650 km2), in which land use and development have obscured the natural fluvial landscape in many parts of the basin. To address this issue we used computer tools to examine the spatial patterns of fluvial landscapes that are associated with five domains of hydro-geomorphic processes and landforms. Using a 5-m digital elevation model, valley-floor surfaces were mapped according to elevation above the channel and proximity to key geomorphic processes. The predicted fluvial landscape is patchily distributed according to hillslope and valley topography, river network structure, and channel elevation profiles. The vast majority of the fluvial landscape in the main segments of the Pas River catchment is presently masked by human infrastructure, with only 15% not impacted by river control structures and development. The reconstructed fluvial landscape provides a catchment scale context to support restoration planning, in which areas of potential ecological productivity and diversity could be targeted for in-channel, floodplain and riparian restoration projects.

With the coming of Web 2.0, several technologies are developed to facilitate creating, sharing and reusing of web resources. In this context, the mashup is a novel approach that allows the user to aggregate multiples services to create a single one with a new user interface. However, a key limitation of existing mashups applications is the need to compute semantic and syntactic similarities between data in different services and create or modify workflows in applications mashups without enlisting the talents of the original developers or vendor. In fact, automatic matching tools help users to facilitate automatic integration of both data and APIs without knowing their structure and semantics. In this paper, the authors suggest a novel approach which consists in building a semantic mashup using a matching tool, domain ontology and a set of patterns to facilitate and automate services and data integration. As a study use case, they develop a semantic mashup application for a travel agency that provides a single interface to users.

Full textAbstract:
It is well-known that the ultra-peripheral territories as Islands present several limitations such as the lack of resources, restricted land, mass tourism, and barriers to movement, and connectivity between urban centers. These obstacles make ultra-peripheral regions suitable case studies considering their territorial governance and consequently, sustainable development and growth. Thus, transportation and infrastructure sustainability in these regions are not an exception. Considering all the obstacles present in these regions, the accessibility and connectivity patterns that the local population has in these territories should be assessed and monitored. Thereby, through exploratory tools, the present research assumes to examine, using accessibility and connectivity indicators, the consequences across the social-economic dimension that the regional transportation and infrastructure should convey to the Azores Islands Archipelago populations. Therefore, this article allows us to set the present situation regarding this region’s accessibility and connectivity patterns, creating an additional tool for supporting the main actors’ design and implementation of these territories’ future plans and strategies. Besides, this study enables us to recognize that Pico, Flores, and São Miguel are the ones with better accessibility patterns within the Azores Archipelago.

Mobile devices can enhance learning and teaching by providing instant feedback and better diagnosis of learning problems, helping design new assessment models, enhancing learner autonomy and creating new formats of enquiry-based activities. The objective of this paper is to investigate the pedagogical impact of mobile voting tools. The authors' research demonstrated that Student Response System (SRS) supported approaches influenced not only lecture design - time management, the mode of material presentation, activity switch patterns - but also learner-teacher interaction, student collaboration and output, formats of activities and tasks. SRS-supported lectures help instructors gradually move towards flipped classrooms and MOOC lecturing. The authors' analysis, based on qualitative and quantitative data collected from two student groups (56 undergraduate students) in the 2012-2013 academic year, showed that SRS supported lectures encouraged foreign language learners to produce more output in the target language, improved their intercultural competence and language skills and enhanced their motivation.

Full textAbstract:
AbstractThis paper investigates detecting patterns in the pressure signal of a compressed air system (CAS) with a load/unload control using a wavelet transform. The pressure signal of a CAS carries useful information about operational events. These events form patterns that can be used as ‘signatures’ for event detection. Such patterns are not always apparent in the time domain and hence the signal was transformed to the time-frequency domain. Three different CAS operating modes were considered: idle, tool activation and faulty. The wavelet transforms of the CAS pressure signal reveal unique features to identify events within each mode. Future work will investigate creating machine learning tools for that utilize these features for fault detection in CAS.

Full textAbstract:
AbstractAssessing present social and biophysical conditions of communities that are at risk of injury due to extreme weather events is an important component of creating future visions of resilience. Spatial patterns of vulnerability to extreme events are manifestations of structural injustice that leave their mark on the built environment and in socio-spatial segregation patterns. Socio-spatial inequity often arises from development practices that favor particular racial and ethnic social groups over others. These segregation patterns are aligned with patterns of exposure to pollution, extreme weather events, and other types of environmental hazards. Spatial vulnerability assessments can be powerful tools for prioritizing where and how cities should make investments for mitigating the impacts of extreme events, and can provide an entry point for asking more fundamental questions about the processes that produce patterns of climate inequity, as well as how to avoid reproducing such processes in the future. Maps express uneven distributions of risk and manifestations of structural inequality in social–ecological–technological systems (SETS). They enable communities to visualize distributional injustice, consider ways in distributions that may be misaligned with cultural values, and develop adaptive practices toward climate justice. Here, we demonstrate approaches for assessing vulnerability to extreme flooding and heat, and show how vulnerability distributions are embedded in landscape patterns that produce uneven risk.

AbstractEducation is rapidly evolving from co-located settings to remote and online learning. However, many proven educational tools are designed for collaborative, co-located classroom work. Effective sketching and ideating tools, such as card-based workshop tools, cannot be applied in remote teaching.This paper explores how the paper-based card and playboard metaphor can be digitized for remote student co-creation via video call sessions. Therefore, a card-based toolkit for co-creating educational games is transformed into a digital representation for remote application. In a between-subject trial with two university student groups (n = 61), it is investigated how users perceive ideation/balancing support and applicability of the technology-enhanced card toolset compared to the paper-based variant. Both groups thereby created an analytic game concept for privacy education.The results remarkably revealed that remote co-creation using the technology-enhanced card and playboard in video call sessions was perceived as significantly more supportive for ideation and game concept balancing. Students also felt more confident to apply the digitized card toolset independently while being more satisfied with their created game concepts. The designed educational game concepts showed comparable patterns between the groups and disclosed the students’ preferences on how games for privacy education should be designed and when and where they would like to play them. Conclusively, design implications for digital card ideation toolsets were synthesized from the findings.

Patterns are distilled forms of knowledge from past experience and expertise in solving recurring problems in a domain. The Semantic Web provides an environment where the knowledge inherent in patterns can be adequately represented to be broadly accessible and be reasoned with. This chapter describes the process of creating OWAP, an ontology in the language OWL for Web Application Patterns. The problems faced in each phase and steps taken to resolve them are given. The significance and limitations of tools during OWAP design, implementation, and testing are outlined. The lessons learned in engineering OWAP are cast as an aggregated list of guidelines. Finally, some directions for future enhancements of OWAP are pointed out.

This chapter will provide a rationale for the importance of implementing a caring culture in the school community, as well as using instructional tools to provide a high level of instruction and care. A summation of ethics theorist Nel Nodding's work is presented to the reader as evidence and motivation for embracing the caring model as an invaluable component of teaching. In conjunction with Nel Nodding's care theory, the author will expand on thinking maps research to demonstrate how thinking maps supports an ethics of care in the classroom, while deepening student learning, enhancing critical thinking skills, and promoting creative thought. Thinking maps are a set of visual tools for supporting instructional practices and improving student performance. It is a language of eight visual patterns each based on a fundamental thinking process. When an educator utilizes this research-based tool, consistently and purposefully in the classroom, the leader is cultivating user independence and fostering a nurturing environment for his/her students.

Maps are representations of the world. They offer summaries or simplifications of data that are collected, attempt to reveal unknowns, to simplify and communicate complex spatial phenomena. Numerous decisions are made in the process of creating a map. Seemingly inconsequential variations of cartographic design decisions offer many ways to illustrate this process. We use an open dataset related to the United Nations Gender Inequality Index to demonstrate design decision points and their output. As governments are increasingly making data open to the public, and map-making tools and software are now more accessible online, these considerations are important both for those making and reading maps online.

Full textAbstract:
Environmental monitoring is a critical process in areas potentially affected by natural disasters. Nowadays, the distributed processing of vast amounts of heterogeneous sensor data in real time is a challenging task. Event processing tools allow creating an event abstraction layer on top of sensor data. Users can define event patterns to filter in real-time the information they are interested in and avoid irrelevant data. Extreme events are usually related to other environmental occurrences, e.g. landslides are related (among others) to precipitations and earthquakes. To be able to determine whether an occurrence could potentially lead to an extreme event, domain knowledge is necessary. Ontologies are helpful for this task, since they are able to capture a representation of knowledge as a set of concepts and relations, within a specific domain. The research presented in this chapter aims at combining event-processing tools with semantic technologies to improve the discovery of environmental data.

Most design activities involve exploring and comparing existing designs. Thus, adopting an eco-conscious approach in the design exploration process can aid environmentally sustainable product design (SPD). One approach for supporting exploration in SPD is through tools based on information visualization (InfoVis). The use of InfoVis for SPD allows data-driven exploration of solutions that is rapid, direct, and supports investigation of questions that the designer may not have identified. Previous work has demonstrated the utility of InfoVis tools for different facets of the lifecycle, e.g. redesign, supply chain exploration, and life cycle assessment. These tools focus on projecting sustainability-related implications back to design. However, to fully realize their potential, future tools must synthesize data in a manner that helps designers view the effects of a design change on all downstream stages. Such tools will have to work across multiple data types, visual representations, and stakeholders. In this paper, we take the first steps towards addressing this challenge by formulating design patterns for visualization and interaction of product lifecycle data. These design patterns were synthesized by reviewing previous works that have successfully created visualization-based tools for SPD. The suggested design patterns can, (1) serve as a guide for creating integrated visualization-based tools for SPD, and (2) help create reusable visual components that aid in quick interface wireframing.

Surface textures helps in controlling the tribological, optical, mechanical, and thermal properties on the surfaces. The recent advancements in precision machining, makes it possible to generate micro/nano patterns on the surfaces with high dimensional control. In the present work an attempt has been made to reduce the thrust force and torque developed during drilling super alloy, Ti-6Al-4V by creating micro dimples on the tool surfaces. Circular dimples having an average diameter of 35 micrometer were created on the flute and margin side of the drill bit using Nd:YAG laser. Scanning electron microscopy analysis has been done to evaluate the quality of generated micro dimples. Drilling experiments were carried out on the titanium alloy in both dry and wet conditions using flute textured, margin textured and non textured tool for understanding the effect of micro textures on the tool. From the force analysis it was observed that in both dry and wet conditions there was a considerable reduction in thrust force and torque. Surface inspections of the drill bit were performed using Stereomicroscope for investigating the titanium buildup on the cutting tool surfaces. Results showed that the margin textured tool performed better than the flute textured and untextured tool in both dry and wet conditions.

As a part of an ongoing effort to develop computerized training tools for cryosurgery, this study presents a computational technique to geometrically deform a three-dimensional organ template in order to generate clinically relevant prostate models. Cryosurgery is the destruction of undesired tissues by freezing, where prostate cryosurgery often involves the complete destruction of the gland. The objective of creating deformed models is to develop a database for computerized training [1]. The challenges in generating a prostate model from a template are associated with asymmetry of the organ, and the variability in growth patterns exhibited in the population of prostate cancer patients.

Many of the agricultural plots within Trinidad and Tobago remain in a state of dormancy due to a critical lack of infrastructure needed for their development. This has contributed to the increasing food import bill which was some TT$5.6 billion over the last couple of years. This overall crop irrigation project aims at assisting the farmers in setting up a proper infrastructure that will utilize natural resources. The lack of pipe water will be substituted by rainwater capture, storage and distribution via drip irrigation. The lack of power for water distribution by irrigation will be obtained by the use of solar power for the pumps. The project will be done in phases. This phase involved at creating a smart estimator to determine the water requirement and the planting land area for the 2-acre plot when the number of plants, type of plants, and the month in which the farmer chooses to start planting are chosen. It will estimate the water storage volume required for the various crops chosen based on the rainfall patterns, crop cycle and the crop water requirement. These output estimates will be based on the land area input, estimated water storage size, estimated tool shed size and produce storage area, and the type or types of crops chosen to farm by the farmer for the plot. The input parameters in the estimator can then be varied by the farmer, to help find an estimated or optimum balance of the number and type of crops, the planting land area, and the water captured and stored, based on the rainfall patterns and the unused land area. The outputs required can be similarly obtained through the use of existing models and software packages, but the tools are not ‘Farmer User Friendly and readily available’.

Full textAbstract:
Rapid and cost effective fabrication of nanostructures is critical for experimental exploration and translation of results for commercial development. While conventional techniques such as E-beam or Focused Ion beam lithography serve some prototyping needs for nano-scale experimentations, cost and rate considerations prohibit use for manufacturing. Specialized lithographic processes [e.g. nanosphere lithography or interference lithography] are also powerful tools in creating nanostructures but provide limited shapes, positioning and size control of nanostructures. In this work, we demonstrated a liquid-free and mask-less electrochemical writing approach using atomic force microscopy (AFM) that is capable of making arbitrary shapes of silver nanostructures in seconds on a solid state super-ionic (AgI)x (AgPO3)(1−x) glass. Under ambient conditions. silver is extracted selectively on super-ionic (AgI)x (AgPO3)(1−x) glass surface by negatively biasing an AFM probe relative to an Ag film counter electrode. Both voltage controlled and current controlled writings demonstrated localized extraction of silver. The current controlled approach is shown to be the preferred writing approach to make repeatable and uniform patterns of silver on (AgI)x AgPO3(1−x), where x represents the mole fraction of AgI in the mixture and the control parameter that tunes the conductivity of the sample. We demonstrated current controlled printing of silver on two different compositions of the material (i.e. (AgI)0.125 (AgPO3 )0.875 and (AgI)0.25(AgPO3)0.75 ). Depending on the magnitude of the constant current and tip speed, line-width of the silver pattern can be ∼150 nm. The length of these patterns are limited to the maximum distance the tip can be moved using the AFM position controls. The substrate being optically transparent allows the use of this writing technique for rapid prototyping plasmonic devices. By using the patterned substrate as a template for replica molding of soft materials such as polydimethylsiloxane (PDMS), this writing technique can also be utilized for high throughput nano-channel fabrication in biofluidics and microfluidics devices.

Full textAbstract:
Cities have been the focus of recent sustainability and climate change mitigation efforts primarily because of unprecedented urban growth and ever-increasing resources consumption. A worrying trend has been the ever-decreasing life of buildings in cities because of premature building obsolescence. Premature building obsolescence has been cited as the major driver of demolition waste which accounts for more than 40% of total waste generated annually. This waste stream poses a bigger challenge as the pressure on natural resources increases with urban growth. A traditional way of looking at the urban sustainability has been from the perspective of the environmental sciences and waste management methods. Analyzing urban areas with design science perspectives could provide novel insights to improve existing resource consumption patterns and transform sustainability growth in cities. This study focuses on the problem of demolition waste arising from the premature building obsolescence in cities. It applies a design research methodology framework for identifying existing problems associated with demolition waste and generating strategies to transform cities into more sustainable urban systems. In the problem clarification phase, a detailed literature review was supported with stakeholder’s interviews to identify the state-of-art for building demolition process and demolition waste. Research was further extended to descriptive study-I phase to carry out a demolition case study and generate support tools to enable transformation in the existing scenario for achieving a desired state. Singapore, a dense city state of South-East Asia has been taken as a case study in this research. Results show that applying design research methods could help open-up a new dimension to solve urban sustainability challenge for built environment. It highlights that material reuse could lead to significant improvement in the built environment sustainability but the challenge associated with realization of material reuse practice needs to be addressed. Descriptive study-I concludes with the strategies on creating a reuse market through entrepreneurial innovation and an alternative material supply chain of secondary materials for regional housing demand. These results highlight the role of design research methods for tackling complex systems level problems in cities.
