Simulating real world applications containing many functionalities using programs tend to become very complex in structure and behaviour. Validating such programs for its correctness require correct outputs and their ability to cope with erroneous scenarios. This work proposes a methodology for the verification of such programs defined using Java, based on their design-time and run-time model, where...
This study aimed to design and develop a cost effective, portable tool as a software application with target games to identify the preferred retinal locus (PRL) in patients with macular diseases and train them using the novel Eccentric Viewing Training Module (EVTM) to further improve their visual abilities such as recognizing faces, reading speed. We have designed a novel software for identifying...
This work brings a Systematic Review on the use of Virtual Reality in Fetal Medicine in order to recover the state of the art on the use of Virtual Reality tools in Fetal Medicine and also which Fetal Medicine areas has been focus of Virtual Reality application. The keywords “Virtual Reality” and “Fetal Medicine”, “Virtual Reality” and “Fetus” were used in both Portuguese and English and the “And”...
The emerging of BIM (Building Information Modeling) techniques will change traditional procedures of design and maintenance for electric substations. In addition, Computational Holography, supported by wearable computers, has the potential to allow simultaneous engineering work, based on mixed reality and computer vision capabilities. It is believed that this set of tools will increase engineering...
Modern ASIC and FPGA based embedded products use model based design, in which both hardware and software are developed in parallel. Previously HW was completed first and the information handed over to SW team, typically in the form of register tables. The information was even manually copied to SW code, making any changes error-prone and laborious. IP-XACT is the most feasible standard to model HW...
High order discretization method is one of the most popular research topics on Computational Fluid Dynamics (CFD). However, the development of visualization tools suited for high order methods obtains not as much attention. Most of the software used to visualize numerical solutions do not support high order data format. To visualize the high order solution, the most common method is to tessellate...
Software engineering, especially design and requirements engineering, is intensely creative. However, practitioners and researchers appear to perceive creativity differently, hindering knowledge transfer. To explore and understand these perceptual differences, this paper combines a systematic mapping study of SE research literature with an interview study of practitioners. The subsequent analysis...
The appearance of MOOCs brings a lot of attentions. Although MOOCs provide the people with more learning opportunities and conditions, there are some disadvantages, such as the practice of the skills and the difficulties in the understanding of the key notes due to the lack of the interaction between the teacher and the students. Virtual reality technology brings the chance to solve these problems...
One difficulty of teaching in mathematics is to present abstract mathematical concepts or laws to students in a simple visual way to promote students' understanding and mastery. Traditionally mathematical teachers tried to explain abstract mathematical concepts and formulas by means of some simple teaching tools and some mathematical models presented by some mathematical software, such as Matlab,...
The visual simulation system which the docking process of replenishment at sea is constructed based on MultiGen Creator and Vega Prime. In a bid to modeling and driving of the visual simulation, a large number of the real-time data should be transformed for simulation in which the entire process of replenishment at sea. According to the complicated power and movement state of the docking mechanism...
Along with the growth of the Internet of Things (IoT), the number of wireless devices and mobile nodes significantly increases and they are connected among them over wireless links. Many application software and network system software for these wireless devices/mobile nodes are being developing. However, we cannot confirm a wireless connection between the two adjacent devices, the network topology...
The unified program architecture of real time vision system (VS) with several fields of view construction is described. The offered architecture provides both onboard and stationary usage. In case of stationary usage, it provides determination of location and trajectory of objects movement in the ordered system of co-ordinates. Principles of open architecture, componential technology and use of standard...
Timeseries line charts are a popular visualization technique but traditionally do not show many lines. We borrow concepts of tiny microtext and path dependent cartographic text to embed labels and additional text directly into lines on line charts, thereby making it easier to identify individual lines in a congested line chart, enabling more lines to be displayed and enabling additional data to be...
The visualization of numeric data is becoming an important element in journalism, and new tools and platforms make the development of data visualization in the news discourse accelerate. In this paper we present an interview study investigating this development in Scandinavian newsrooms. Editorial leaders, data journalists, graphic designers, and developers in 10 major news organizations in Norway,...
MetricAttitude [18] is a visualization approach implemented in an environment that provides a mental picture of an object-oriented software by means of polymetric views of classes. In this paper, we describe a qualitative investigation we have conducted with a focus group involving developers aiming at evaluating their viewpoint on the relevance of the support MetricAttitude provides to perform comprehension...
Novice researchers have difficulties in operationalization (breaking down of abstract concepts to measurables) and generalization (generalize the findings to make claims). We have designed a system called OPeD (Operationalizing using ProblEm Decomposition), for teaching learning of operationalization. OPeD trains novice researchers in operationalization through problem decomposition. OPeD is based...
Open source software (OSS)-based product development takes advantage of feature updates and bug fixes from OSS communities. However, when we customize the OSS and do not return the changes back to the OSS communities, our customization and the updates sometimes conflict. That makes it difficult to apply forthcoming OSS updates since we need to grasp the software changes appropriately. We propose a...
Coordination in software projects is a challenge, particularly when it comes to distributed software development (DSD). Agile software development is a well-known paradigm for improving software development; however, there is little understanding of its impact on DSD projects. This paper describes an empirical study conducted within two Software Factory settings in Finland and Italy to investigate...
Metamodelling and model transformation play important roles in model-driven engineering as they can be used to define domain-specific modelling languages. During the modelling phase, modellers encode domain knowledge into models which may include both structural and behavioral aspects of a system. The contribution of this paper is a new web-based metamodelling and model transformation tool called...
