Models are commonly used in software testing to select test suites. Application of mutation testing at a model level can contribute to reliable and early assessment of the quality of the test suites. It can also support selection of test suites achieving high fault detection rates. The main issue related to using mutation testing at the early development stage is to determine how reliably the quality...
IN THIS presentation we will argue that Big Data technologies can contribute in an important way to an unprecedented breakthrough in the understanding of oceans as a factor in climate change, in transportation, and in supplying humanity with its important food component.
Ensemble learning is being considered as one of the most well-established and efficient techniques in the contemporary machine learning. The key to the satisfactory performance of such combined models lies in the supplied base learners and selected combination strategy. In this paper we will focus on the former issue. Having classifiers that are of high individual quality and complementary to each...
In computer architecture, speculative execution is the process of executing instructions ahead of their normal schedule[1]. Grama et al.[2] introduce the concept of speculative decomposition as a possibility to execute one or more of possible branches in parallel with computation which are expected to determine the branch choice. The following paper introduces the method of speculative query execution...
Knowledge Management methods, techniques and experience can bring a considerable help in preventing all kind of risks. The current economic context amplified the existing risks and introduced new ones such as environmental, political and social. Among the most critical risks of this century is this of lost of knowledge and “memory” in particular in industry involved in long-term activities. After...
Rules and processes constitute powerful representation forms. Although the same notions can be expressed in both of these representations, there is a significant difference in abstraction levels between processes and rules. In practice, rules are mostly used for the specification of rule task logic in processes. In this paper, we present various options where and how rules can be perceived in business...
Social Media has become indispensable for market penetration. It is a beneficial communication platform for understanding the customer focus. Effective use of this media for image creation, customer access, knowledge accumulation and trend analysis, creates competitive advantages. This research is designed to analyze social media strategies of global enterprises and evaluate the value of social media...
With the evolution of mobile technology, many devices are introduced with very limited screen sizes like smart glasses. This technology must be accompanied with new visualization techniques. A classic interface can't meet the expectations of the user who becomes increasingly hard to please. The challenge is to display information and allow the user a better navigation with less effort especially in...
This paper aims to extend current research in the area of on-line business-to-business clients preferences. A quantitative research in a form of transaction log analysis (TLA) performed by the authors allow to conclude that search log and shop basket logs are sources of viable information about business customers. Transaction log analysis allows to identify different customer groups, such as searchers...
This document describes the concept of urban knowledge. Main aim of this paper is to define term, describe assumptions and possibilities of use. The paper consists of introduction, five chapters and the summary. In introduction author presents background of conducted research. First chapter is the explanation of the urban knowledge phenomenon. Second presents further characteristic with brief classification...
Business Process models help to visualize processes of an organization. In enterprises, these processes are often specified in internal regulations, resolutions or other law acts of a company. Such descriptions, like task lists, have mostly form of enumerated lists or spreadsheets. We present a method how to generate a BPMN process model from a spreadsheet-based representation. In contrast to the...
In this article we introduce QtBiVis - a novel software intended for the comparative analysis of biclustering results. This modular tool has been efficiently implemented in C++ with Qt framework GUI. It may be successfully used for coverage analysis of the results of biclustering as well filtering or sorting biclusters by Gene Ontology (GO) identifiers or bicluster enrichment values. It may also be...
Effective project management requires the development of a realistic plan which aims to ensure the success of the project and ultimately deliver a high quality product to customers. However, experience shows that the majority of software vendors managing projects suffer from numerous problems to provide usability in IT solutions and complete a project in a given time with success. In this paper we...
Smart systems have to deal with environmental changes and react for adapting their behavior to changes in the operating conditions, so to always meet users' expectations. This is fundamental for those systems operating in open environments that may change frequently. Smart environments are complex systems that more than others are affected by these issues. In this paper, we propose a normative framework...
Currently, bike-sharing systems undergo a rapid expansion due to technical improvements in the operation combined with an increased environmental and health awareness of people. When it comes to the acceptance of such systems the reliability is of great importance. It depends heavily on the availability of bicycles at the stations. But, in spite of truck-based redistribution efforts by the operators,...
Emotions, moods and temperament influence our behaviour in every aspect of life. Until now plenty of research has been conducted and many theories have been proposed to explain the role of emotions within the working environment. However, in the field of software engineering, interest in the role of human factors in the process of software development is relatively new. In the paper the research design...
In this contribution we present an approach on how to include local soft constraints in the fully distributed algorithm COHDA for the task of energy units scheduling in virtual power plants (VPP). We show how a flexibility representation based on surrogate models is extended and trained using soft constraints like avoiding frequent cold starts of combined heat and power plants. During the task of...
The crucial element of any agile project is people. Not surprisingly, principles and values such as “espect for people”, “Communication and Collaboration”, “Lead using a team approach”, and “Learn and improve continuously” are an integral part of Open Kanban. However, Open Kanban has not provided any tools or techniques to aid the human side of software development. Moreover, as a Lean initiative,...
Agent-Based Modeling and Simulation (ABMS) is a very useful means for producing high quality models during simulation studies. When ABMS is part of a methodological approach it becomes important to have a method for identifying the objectives of the simulation study in a disciplined fashion. In this work we propose a set of guidelines for properly capturing and representing the goals of the simulations...
