Implementing large and modular C programs is tricky, because there hardly is any support by the C programming language and hardly any guidance for implementing large C programs in a way that they become modular and thus maintainable. In order to ...

This paper compares three structured formats for capturing and sharing design knowledge that have evolved in different disciplines: patterns, design claims, and assertions. It identifies the elements of each format, maps between similar elements, and ...

In safety-critical systems keeping complete trace of requirements and detailed testing is an extremely relevant part of software development life cycle. Safety standards like ISO 26262, DO178C and many others prescribe that critical requirements must be ...

Command, is a behavioral pattern from the Gang of Four catalog that allows us to structure an application with respect to primitive actions that can be easily managed and executed. The main idea is to decouple the objects that invoke actions from the ...

Extract Method is probably the most commonly used refactoring. Although it may seem quite simple at a first glance, there are many cases that it can become fairly complex. Local variables and parameters can make this refactoring difficult to implement. ...

Building a chatbot with an iterative development process poses certain challenges for the chatbot developer. The developer is expected to produce a deployable version of the chatbot at the end of a short development cycle. Every iteration should ...

With the rapid evolution of technological, economic, and regulatory landscapes, contemporary blockchain platforms are all but certain to undergo major changes. Therefore, the applications that rely on them will eventually need to migrate from one ...

This article deals with the question of how to effectively position yourself when leading change. On the one hand, this question includes the issue of positioning yourself in relation to your surroundings and their dynamics in the first place; on the ...

Remote Application Programming Interfaces (APIs), as for instance offered in microservices architectures, are used in almost any distributed system today and are thus enablers for many digitalization efforts. It is hard to design such APIs so that they ...

This paper introduces different applications of the 'Wholeness Egg' method in everyday life. It was originally invented by Iba as a way of designing workshops, based on Christopher Alexander's idea of wholeness and centers. Since we presented a paper '...

Remote Application Programming Interfaces (APIs) are used in almost any distributed system today, for instance in microservices-based systems, and are thus enablers for many digitalization efforts. API design not only impacts whether software provided ...

Patterns are powerful when used in combinations. Identifying relationships between patterns is challenging. The existing approaches and pattern formats reflect the relationships with other patterns in a very informal and traditional way. We are ...

This paper presents a set of patterns for user interface designers to help users better protect themselves from cyberattacks. The basic idea is to create and support mental models of cybersecurity that resembles the way people manage security in the ...

Trusted Computing (TC) is a valuable technology to use when we need to process highly sensitive data and several variants of it are now available. We present here a pattern that describes the architecture of a standard for TC, the Trusted Platform ...

The present paper details the process we have carried out in order to articulate, assemble, and validate design values, principles and patterns for task-based technology-enhanced language learning. During the first phase, we identified an initial set of ...

Self-sovereign identity is a new identity management paradigm that allows entities to really have the ownership of their identity data and control their use without involving any intermediary. Blockchain is an enabling technology for building self-...

This paper presents a concise pattern language that has been developed for designing online learning and teaching. The aim of these patterns is to facilitate novice teachers in designing both their online environments and learning experiences in a ...

Many Cerebral Vascular Accident (CVA) patients suffer from gait and balance problems, which have a large impact on daily functioning. During clinical rehabilitation, a multidisciplinary team uses advanced training facilities to help patients regain ...

This paper describes three interaction patterns for user interfaces of consumer Internet of Things apps. Two patterns address user interaction problems associated with the use of geolocation and machine learning to achieve automation and personalisation ...

In this paper, we present patterns for building customer relationships in a pattern language for value-creation marketing. This pattern language is a collection of practical knowledge to realize successful business and commerce that offers new value, ...

In this paper, we propose knacks for creating pattern languages that encourage readers to practice. The knacks were extracted from Takashi Iba as an expert in pattern language creation and members of Iba laboratory, to investigate their process of ...

Even companies with strong financial records and glorious histories in exploring opportunities and exploiting markets must take their path into a digital business transformation. But they are sometimes trapped in cultural heritage because worked well ...

The paper presents six selected patterns, namely, Sense in the Context, Thorough Rewriting, Vocabulary in Hand, Mode Switching, Improving Pronunciation, and Tongue Exercise, for improving foreign language skills when studying abroad. The pattern ...

Incremental Grading is a student-driven assessment approach where students have the responsibility to grade their own work based on pre-defined assessment criteria, usually rubrics. The desired outcomes of Incremental Grading are higher self-assessment ...

Internet-of-Things systems are assemblies of highly-distributed and heterogeneous parts that, in orchestration, work to provide valuable services to end-users in many scenarios. These systems depend on the correct operation of sensors, actuators, and ...

Fuel consumption and road throughput are the foremost problems faced by the transportation industry. The cost of fuel is a large share of total transportation costs. Vehicle platooning offers a solution to this problem. Vehicle platoon is a group of ...

Software documentation is an important part of the captured knowledge of a software project and documentation patterns have often been used as a systematic way to describe good practices on software documentation. Still, many software teams are ...

While pattern mining is characterized by empirical examinations the applied solutions propagated in the patterns are only rarely the subject or the result of empirical tests. However, confidence that a pattern will serve its purpose can only be obtained ...

Over the past decades, the emergence of agile development approaches has transformed the way software is developed. Even though systems are getting more and more complex, companies have to develop and release software faster and at the same time ...

Communication is crucial in agile contexts due to the need for collaboration and the number of different people involved, ranging from developers to users and business people. This communication should be effective to ensure everyone is on the same page;...
