The colors of characters suitable to presentation slides were proposed. Here, five color combinations were proposed. A combination has three colors of “Base color,” “Main color,” and “Accent color.” The “Base color” is for the background. The color white is used as the “Base color.” The “Main color” is for the part becoming the frame. The “Accent color” is for the place where we want to emphasize...
Internet-native audio-visual services are witnessing rapid development. Among these services, object-based audiovisual services are gaining importance. In 2014, we established the Software Defined Media (sDM) consortium to target new research areas and markets involving object-based digital media and Internet-by-design audio-visual environments. In this paper, we introduce the SDM architecture that...
Context: Agile software processes are more frequently being integrated with aspects of human centered design given the commonalities that the two approaches share, such as user involvement, importance attributed to testing and prototyping practices, iterative design and so on. Goal: tailor a SCRUM-based process by integrating it and adapting it with Human Centered Design (HCD) practices. Method: action...
In recent years, several important initiatives have appeared worldwide, aimed at bringing significant innovation in industrial networked systems (INSs). As an example, the Industry 4.0 and Factory of the Future frameworks are paving the way to modern intelligent factories, where issues such as the communication complexity between smart devices and system on-the-fly reconfiguration are dealt with in...
Modern vehicles are equipped with several interconnected sensors on board for monitoring and diagnosis purposes; their availability is a main driver for the development of novel applications in the smart vehicle domain. In this paper, we propose a Docker container-based platform as solution for implementing customized smart car applications. Through a proof-of-concept prototype—developed on a Raspberry...
Preschoolers as digital native cannot avoid gadgets. Game applications are more accessible to them. People believe that games have a negative impact such as bad character and violence. Nevertheless, the game can be developed into a fun tool. This research aimed to design a game prototype boosting cognitive abilities for preschoolers. Prototyping and testing the game system were the method. A preschoolers'...
Developing for devices like smartphones, tablets or smartwatches is more than just "shipping code". Especially in mobile development there is a strong focus on user interface design and user experience. In order to explore the design space, development teams and designers need early feedback from users testing the designs. Continuous Delivery (CD) is a well-established technique for the...
Build systems play a crucial role in modern software engineering. Recent studies have shown that many builds fail, mostly due to neglected maintenance. This blocks teams from continuing the development and costs time and resources to fix. The target of the thesis is to reduce build breakage by investigating changes that lead to failing builds, identifying bad and best practices for build configuration,...
Information and Communication Technology (ICT) is one of the key enablers for including underserved communities in economic and societal development across the world. Our research analyzes several banking service projects developing technical solutions for rural India. This poster presents an experience report based on systematic debriefing of involved project leaders and initiators, triangulated...
The new paradigm of Software Defined Networking (SDN) although has great potential to address the complex problems presented by enterprise networks, it has its own deployment and scalability issues. Further, a full SDN deployment has its own business and economic challenges. A smooth transition from legacy networks to SDN (disruption free, accommodating budget constraints, with progressive improvement...
We present Catena, an efficiently-verifiable Bitcoinwitnessing scheme. Catena enables any number of thin clients, such as mobile phones, to efficiently agree on a log of application-specific statements managed by an adversarial server. Catenaimplements a log as an OP_RETURN transaction chain andprevents forks in the log by leveraging Bitcoin's security againstdouble spends. Specifically, if a log...
Automated unit test generation has been extensively studied in the literature in recent years. Previous studies on open source systems have shown that test generation tools are quite effective at detecting faults, but how effective and applicable are they in an industrial application? In this paper, we investigate this question using a life insurance and pension products calculator engine owned by...
Storytelling is an important but often underestimated practice in software engineering. Whereas existing research widely regards storytelling as creating a common understanding between developers and users, we argue that storytelling and prototyping are intertwined practices for innovators to persuade decision makers. Based on a two-year qualitative case study in two innovating software firms, we...
We present a versatile FPGA-based evaluation platformfor exploring alternative execution strategies on disaggregatedenvironments for applications, considering differentprocessing block types: compute cores, memory, and accelerators. Developers can interconnect different blocks types in orderto create optimal configurations. A user-level software libraryallows quick mapping of applications on real...
While Systems Engineering has come a long way since its early beginning over six decades ago, it is still facing challenges in gaining the same degree of rigour and precision that is found in the theorical foundation of other engineering domains. Systems Engineering has always incorporate tools and methods from other engineering domains and adapted them to fit the purpose of engineering systems. This...
Measurement-based timing analysis approaches are increasingly making their way into several industrial domains on account of their good cost-benefit ratio. The trustworthiness of those methods, however, suffers from the limitation that their results are only valid for the particular paths and execution conditions that the user is able to explore with the available input vectors. It is generally not...
New and non-traditional movements in the engineering fields potentially have a positive impact on classical systems engineering models in terms of promoting innovation. These movements include off shoots of the Agile Manifesto such as Agile Software Engineering, Agile Software Systems Engineering and Agile Project Management, the rise and popularity of Design Thinking as practiced by IDEO and others...
Docker containers run from Docker images, which can be distributed through so-called Docker registries. The currently available support for searching images in registries is however limited. Available registries (e.g., Docker Hub) only permit searching images "by name", i.e. by specifying a term occurring in the image name, in the image description or in the name of the user that created...
The ability to replicate and reproduce scientific results has become an increasingly important topic for many academic disciplines. In computer science and, more specifically, software engineering, contributions of scientific work rely on developed algorithms, tools and prototypes, quantitative evaluations, and other computational analyses. Published code and data come with many undocumented assumptions,...
Industry 4.0 (I4.0) closed-loop control applications require ultra low-latency and ultra high reliability. Generalized Frequency Division Multiplexing (GFDM) promises to meet these requirements in conjunction with low Out-Of-Band (OOB) emissions. We present latency measurements of an open-source, modular, portable GFDM software implementation using the GNU Radio framework. The used implementation...
