The scalability of business process model shows the ability of a system to handle the amount of provided business process activity. In business process management, scalability is used to compare the size of a business process model to other business process models. This research focused on measuring the scalability of business process models. Every business processes were modeled using Petri Net....
Complexity is a term that is currently used not only in research articles but also in the methodologies and standards used to manage information and projects. The complexity can represent the size of a system, process, program or project, the number of functions and the cost of their acquisition, operation and maintenance. Within the context of this work, the complexity is a variable that represents...
Magnetoencephalography (MEG) is a brain imaging method affording real-time temporal, and adequate spatial resolution to reveal aberrant neurophysiological function associated with dyslexia. In this study we analyzed sensor-level resting-state neuromagnetic recordings from 25 reading-disabled children and 27 non-impaired readers under the notion of symbolic dynamics and complexity analysis. We compared...
The paper presents analysis and comparison of complexity of selected algorithms of motion estimation used in video compression. With the use of own, highly optimized software implementation the authors explored complexity of the methods applied in the framework of the new High Efficiency Video Compression (HEVC) technology. The influence of many different factors on motion estimation complexity has...
The development of computational thinking skills through computer programming is a major topic in education, as governments around the world are introducing these skills in the school curriculum. In consequence, educators and students are facing this discipline for the first time. Although there are many technologies that assist teachers and learners in the learning of this competence, there is a...
For organizations undergoing agile and lean transformation, it can be difficult to get meaningful, actionable insights into progress and impediments. Teams and organizations are best understood as complex adaptive human systems. Understanding what is happening in such systems requires approaches grounded in the complexity sciences and social sciences. This paper describes an approach using complexity...
During the past decade, the Web has become increasingly more popular and thus more important for delivery of content and services over the Internet. At the same time, the number of requested objects, their size and delivery mechanisms for popular websites have become more complex. This in turn has various implications including the impact on page loading time that directly affects the experience of...
Complexity and Uncertainty are undeniably foundations of many structural and analytical aspects on every domain of modern science and technology plus associated standard sets like ones with IEEE, sadly though there is not a commonly agreed description for them, to be applicable literally everywhere. Here, author tries to revisit complexity and uncertainty from philosophical, logical and measurement...
In order to minimize vulnerabilities and achieve target level security, quantification of security is necessary. Unfortunately, quantitative estimation of security in earlier stage of software development life cycle (SDLC) is largely missing. The design phase of software development provides the foundation for secure software. Reducing vulnerability at this phase minimizes rework in subsequent development...
The complexity of application landscapes (AL) has been identified as one of the major challenges in enterprise architecture (EA) management for quite some time. Since there is no agreed upon definition of the term complexity in general or in the context of EA management in particular, literature offers a broad variety of concepts and measurements. Therefore, the main purpose of this paper is to (1)...
Using design models instead of executable code has shown itself to be an efficient way of increasing abstraction level of software development. However, applying established code-based software engineering methods to design models can be a challenge - due to different abstraction levels, the same metrics as for code are not applicable for the design models. One of practical challenges in using metrics...
Service-orientation is a modern approach in building software systems and it has been applied successfully to develop of many domains of software systems. The service-oriented design is the key phase, and assessing the quality at this level is very essential to reduce the cost and effort of the implementation phase and enhance the quality of software applications. In order to assess the quality of...
Complexity is an important attribute to determine the software quality. Software complexity can be measured during the design phase before implementation of system. At the design phase, UML class diagram is the important diagram to show the relationships among the classes of objects in the system. In this paper, we measure the complexity of object-oriented software at design phase to predict the fault-prone...
Temporal logics over general linear time allow us to capture continuous properties in applications such as distributed systems, natural language, message passing and A.I. modelling of human reasoning. Linear time structures, however, can exhibit a wide range of behaviours that are hard to reason with, or even describe finitely. Recently, a formal language of Model Expressions has been proposed to...
Near maximum-likelihood (ML) detections based on the tree search can approach the optimal performance with reduced complexity in Multiple-Input Multiple-Output (MIMO) systems. The breadth-first scheme is widely applied in practical systems for its stable and upper-bounded throughput. However, the major drawback of breadth-first detection is still the relatively high computational complexity. In this...
We present our research towards the design of a computational framework capable of modelling the formation and evolution of global patterns (i.e. group structures) in a population of social individuals. The framework is intended to be used in collaborative environments, e.g. social serious games and computer simulations of artificial societies. The theoretical basis of our research, together with...
Service-oriented architectures (SOA) can be considered as an enabling methodology for Cloud Computing and the IT's industrialization, standardization and commodity approach. The efforts to effectively introduce SOA were driven by the evermore increasing complexity and volume of information to be consumed. This paper discusses in this context some major quality characteristics of SOA systems and new...
In this paper, we describe a new process to collect, calculate, archive, and distribute interesting metrics for all the packages in the standard Debian GNU/Linux installation. Our method replicates and extends previous work done by other groups studying free and open source software systems (FLOSS) in three important ways. First, although there have been other previous studies that attempted to collect...
Processor design and implementation is a complex and resource intensive enterprise. Ideally, designers should be able to quantify the design time implications of their architectural proposals, in order to make more educated decisions and design trade offs. To address the lack of quantitative methodologies to estimate processor design time, this paper introduces a new class of event-driven simulation:...
The software product line (PL) architecture (PLA) is one of the most important PL core assets as it is the abstraction of the products that can be generated, and it represents similarities and variabilities of a PL. Its quality attributes analysis and evaluation can serve as a basis for analyzing the managerial and economical values of a PL. We proposed metrics for PLA complexity and extensibility...
