Effectuation principles are a way to master situations of uncertainty. Researcher detected them by analyzing how entrepreneurs behave when pursuing business ideas. Some people intuitively perceive effectuation the way they are already working. Others ...

This paper introduces 'Wholeness Egg' as an effective technique for designing 'living' workshops. Christopher Alexander who explored the beauty of architecture emphasized that a creation is about making the design come to life as much as possible. He ...

Blockchain is an emerging technology that enables new forms of decentralized software architectures, where distributed components can reach agreements on shared system states without trusting a central integration point. Blockchain provides a shared ...

The Industry 4.0 initiative is pushing traditional production systems and methodologies through fundamental changes. In traditional industries such as manufacturing, utilities, and infrastructure monitoring, customers are demanding more flexibility and ...

Searching is one of the fundamental tasks in Computer Science. An intuitive way to search is to do it linearly, that is, start at the beginning of the dataset and continue till the searched-for item is found or nothing is found. However, as the volume ...

Cloud software continues to expand globally, highly motivated by how widespread the Internet is and the possibilities it unlocks with cloud computing. Still, cloud development has some intrinsic properties to it, making it complex to unexperienced ...

In this paper, we present the concept of patlet cards. A deck of patlet cards can be used in workshops with potential users of patterns. Each card contains the basic information about a pattern. Workshop participants can locate the cards (i.e. the ...

Expressing variability in graphical process models can lead to large and complicated models even for expressing rather simple situations. However, expressing variability in process models is important in many processes. During the execution of a process,...

The design and evolution of Application Programming Interfaces (APIs) in microservices architectures is challenging. General design issues in integration and programming have been covered in great detail in many pattern languages since the beginnings of ...

With the introduction of Internet-of-Things (IoT) and cyber-physical system (CPS) concepts the industrial automation sector is undergoing enormous change towards highly interconnected and globally distributed automation systems. Following this trend the ...

Numerous authorization models have been proposed for relational databases. On the other hand, several NoSQL databases used in Big Data applications use a new model appropriate to their requirements for structure, speed, and large amount of data. This ...

Systems are built for a purpose. The purpose transacted is usually handled by the processing part of a system and is observed and adjusted by coordination parts. In principle, these two kinds of system parts share the same target resource; the thing ...

In this paper, the design patterns Uncertain Number and Propagation Strategy are presented. They are useful for storing uncertainties of values and propagating them throughout calculations in an application. Uncertain Number represents a numerical value ...

Modeling is an important activity in the software development process whose output are design artefacts that describe the resulting software from a high-level perspective. Recent research investigates the role of models at runtime and the results ...

The General Data Protection Regulation mandates data protection in the European Union. This includes data protection by design and having privacy-preserving defaults. This legislation has been in force since May 2018, promising severe consequences for ...

How to change the communication behavior of devices participating in a network with an already defined topology? This question describes the fundamental problem, which the Message Encapsulation Pattern aims to solve. Network participants usually follow ...

Adult learners have specific features that differentiate them from children and the young. This specificity has been overlooked by an overwhelming part of the theoretical and applied research on education, which focuses on the early stages of life. ...

With multiple parallel running software development initiatives and products, the overview of what is going on has to be kept in sight to derive suitable architectural and technical decisions. In an environment without a proper decision-making process ...

Numerous attacks on Internet of Things (IoT) devices have shown that security cannot be neglected, even when building devices with just a few kB of memory. While it is common sense to run regular software updates and use state-of-the-art security on ...

This paper describes six patterns of hybrid education. Hybrid education is a way of overlapping and blending different concepts at the same time, such as online and offline, formal and informal. The patterns focus on bringing experience from the outside ...

In a straightforward meta-level shift of focus, we use design patterns as a medium and process for capturing insight about the process of design. We survey mainstream design genres, and draw conclusions about how they can help inform the design of ...

This paper integrates previously published patterns (many of them documented by the author) for open source businesses through narratives. An open source business employs open source as a strategy to strengthen its business model. The paper makes three ...

A basic prerequisite for any daily development task is to understand the source code that we are working with. To this end, the source code should be clean. Usually, it is up to us, the developers, to keep the source code clean. However, often there are ...

The Idioms for Synchronization Mechanisms is a collection of patterns related with the implementation of synchronization mechanisms for the communication components of parallel software systems. The selection of these idioms take as input information (a)...

The Architectural Patterns for Parallel Programming is a collection of patterns related with a method for developing the coordination structure of parallel software systems. These architectural patterns take as input information (a) the available ...

The Design Patterns for Communication Components is a collection of patterns related with a method for developing the communication sub-systems of parallel software systems. The application of these design patterns take as input information (a) the ...

In this paper, we propose a function "Pattern Experience Chart Generator" necessary to realize the aim of the Pattern Language Platform "Patterns We Live By", which is a web application that supporting the "practice" of patterns by ensuring that they ...

This paper extends our Magic Backlog Patterns collection with three additional patterns for managing the work of a program- or rather how to deal with coordinating the work of projects which are part of a larger program and where there may be ...

Most companies developing an operating software systems reach a point of time when the architecture of one or more systems is questioned. Triggers are, for example, serious operational issues, like inconsistent data, failures, or high complexity of the ...
