First, the 3D coordinates are pre-processed to be transformed into a specific form. Then these 3D coordinates are changed into 1D data by making the three coordinates of a vertex represented by only a position number, which is made of a large integer. To minimize the integers, they are sorted and the differences between two adjacent vertexes are stored in a vertex table. In addition to the technique of geometry compression on coordinates, an improved method for storing the compressed topological data in a facet table is proposed to make the method more complete and efficient. The experimental results show that the proposed method has a better compression rate than the latest method of lossless geometry compression, the Isenburg-Lindstrom-Snoeyink method. The theoretical analysis and the experiment results also show that the important decompression time of the new method is short. Though the new method is explained in the case of a triangular grid, it can also be used in other forms of grid model.Keywords: triangular mesh, model, lossless, compressionPublished: 12.07.2017; Views: 579; Downloads: 132 Full text (332,44 KB)This document has many files!

Our aim is a control of modular autonomous systems in rescue robotics. One of the basic problems with autonomous robotics is the execution part where the control commands (translation and rotational velocities) are produced for mobile bases. Therefore we have focused on this area because there is only a small amount of available path following software for skid-steered mobile robots. Our goal was to develop a velocity controller that could be used for multiple skid-steered mobile bases. We considered differential drive mobile bases such as tracked skid-steering mobile bases. Our approach is based on an arc fitting algorithm, which takes into account the robot constraints and kinematical model. It produces a continuous trajectory where fitting to the given path is adapted based on given parameters. Moreover, we have included orientation angle compensation while the mobile robot is moving and ground inclination compensation. Our rescue robot is described, together with the simulation setup and algorithm implementation. We compared our algorithm to the Hector-based software and curvature velocity approach. The results for the proposed algorithm are shown for the simulation results and the experiment.Keywords: mobile robot, arc fitting, path following, velocity control, rescue robotPublished: 12.07.2017; Views: 459; Downloads: 153 Full text (1,43 MB)This document has many files!

Many different disciplines investigate methods and systems closely related to the design of hybrid societies. A stronger collaboration between these disciplines could allow for re-use of methods and create significant synergies. We identify three main areas of challenges in the design of self-organizing hybrid societies. First, we identify the formalization challenge. There is an urgent need for a generic model that allows a description and comparison of collective hybrid societies. Second, we identify the system design challenge. Starting from the formal specification of the system, we need to develop an integrated design process. Third, we identify the challenge of interdisciplinarity. Current research on self-organizing hybrid societies stretches over many different fields and hence requires the re-use and synthesis of methods at intersections between disciplines. We then conclude by presenting our perspective for future approaches with high potential in this area.Keywords: hybrid society, bio-hybrid, distributed, self-organization, design, intedisciplinaryPublished: 10.07.2017; Views: 361; Downloads: 178 Full text (603,11 KB)This document has many files!

Taking from the well-known definition of a community in the realm of network science, namely that people within a community share significantly more links with each other as they do outside of this community, we propose that citation cartels are defined as groups of authors that cite each other disproportionately more than they do other groups of authors that work on the same subject. Evidently, the identification of citation cartels is somewhat different, although similar to the identification of communities in networks. We systematically expose the problem, provide theoretical examples, and outline an algorithmic guide on how to approach the subject.Keywords: citation network, citation cartel, network science, community detection, cooperationPublished: 10.07.2017; Views: 549; Downloads: 154 Full text (855,89 KB)This document has many files!

Yero, 2016, original scientific articleAbstract: Closed monopolies in graphs have a quite long range of applications in several problems related to overcoming failures, since they frequently have some common approaches around the notion of majorities, for instance to consensus problems, diagnosis problems or voting systems. We introduce here open ▫$k$▫-monopolies in graphs which are closely related to different parameters in graphs. Given a graph ▫$G=(V,E)$▫ and ▫$X \subseteq V$▫, if ▫$\delta_X(v)$▫ is the number of neighbors ▫$v$▫ has in ▫$X$▫, ▫$k$▫ is an integer and ▫$t$▫ is a positive integer, then we establish in this article a connection between the following three concepts: (1) Given a nonempty set ▫$M\subseteq V$▫ a vertex ▫$v$▫ of ▫$G$▫ is said to be ▫$k$▫-controlled by ▫$M$▫ if ▫$\delta_M(v)\ge \frac{\delta_V(v)}{2}+k$▫. The set ▫$M$▫ is called an open ▫$k$▫-monopoly for ▫$G$▫ if it ▫$k$▫-controls every vertex ▫$v$▫ of ▫$G$▫. (2) A function ▫$f: V\rightarrow \{-1,1\}$▫ is called a signed total ▫$t$▫-dominating function for ▫$G$▫ if ▫$f(N(v))=\sum_{v\in N(v)}f(v)\geq t$▫ for all ▫$v\in V$▫. (3) A nonempty set ▫$S\subseteq V$▫ is a global (defensive and offensive) ▫$k$▫-alliance in ▫$G$▫ if ▫$\delta_S(v)\ge \delta_{V-S}(v)+k$▫ holds for every ▫$v\in V$▫. In this article we prove that the problem of computing the minimum cardinality of an open ▫$0$▫-monopoly in a graph is NP-complete even restricted to bipartite or chordal graphs. In addition we present some general bounds for the minimum cardinality of open ▫$k$▫-monopolies and we derive some exact values.Keywords: open k-monopolies, k-signed total domination, global defensive k-alliance, global offensive k-alliancePublished: 10.07.2017; Views: 252; Downloads: 41 Full text (181,59 KB)This document has many files!

Yero, 2014, original scientific articleAbstract: A graph ▫$G$▫ is an efficient open domination graph if there exists a subset ▫$D$▫ of ▫$V(G)$▫ for which the open neighborhoods centered in vertices of ▫$D$▫ form a partition of ▫$V(G)$▫. We completely describe efficient open domination graphs among lexicographic, strong, and disjunctive products of graphs. For the Cartesian product we give a characterization when one factor is ▫$K_2$▫.Keywords: graph theory, efficient open domination, graph products, total dominationPublished: 10.07.2017; Views: 259; Downloads: 40 Full text (804,78 KB)This document has many files!

Current research focuses on measuring complexity of XML Schemas and mainly do not consider other quality aspects. This paper proposes a novel quality measuring approach, based on existing software engineering metrics, additionally defining the quality aspects of XML Schemas using the following steps: (1) definition of six schema quality aspects, (2) adoption of 25 directly measurable XML Schema variables, (3) proposition of six composite metrics, applying 25 measured variables and (4) composite metrics validation. An experiment was conducted using 250 standard XML Schemas collected from available e-business information systems. The results illustrate the influence of XML Schemaʼs characteristics on its quality and evaluate the applicability of metrics in the measurement process, a useful tool for software developers while building or adopting XML Schemas.Keywords: XML, metrics, quality variables, quality index, evaluation, validationPublished: 06.07.2017; Views: 404; Downloads: 199 Full text (765,37 KB)This document has many files!

Researchers have proposed different security mechanisms to ensure the integrity and confidentiality of logs. However, applying current secure logging schemes on heterogeneous formats of logs is tedious. Here, we propose Forensics Aware Language (FAL), a domain-specific language (DSL) through which we can apply a secure logging mechanism on any format of logs. Using FAL, we can define log structure, which represents the format of logs and ensures the security properties of a chosen secure logging scheme. This log structure can later be used by FAL to serve two purposes: it can be used to store system logs securely and it will help application developers for secure application logging by generating the required source code.Keywords: domain-specific language, DSL, secure logging, audit trail, digital forensicsPublished: 06.07.2017; Views: 317; Downloads: 171 Full text (526,42 KB)This document has many files!

However, both the creation and use of template libraries is hindered by the fact that the language does not allow programmers to specify constraints on generic types. To date, no proposal to update the language to provide concepts has survived the committee process. Until that time comes, as a form of early support, this paper introduces SimpleConcepts, an extension to C++11 that provides support for concepts, sets of constraints on generic types. SimpleConcepts features are parsed according to an island grammar and source-to-source translation is used to lower concepts to pure C++11 code.Keywords: generic programming, C++ templates, C++ conceptsPublished: 06.07.2017; Views: 341; Downloads: 153 Full text (299,20 KB)This document has many files!

In this paper we are concerned with Program Comprehension issues applied to Domain Specific Languages (DSLs). We are now willing to understand how techniques and tools for the comprehension of traditional programming languages fit in the understanding of DSLs. Being the language tailored for the description of problems in a specific domain, we believe that specific visualizations (at a higher abstraction level, closer to the problem level) could and should be defined to enhance the comprehension of the descriptions in that particular domain.Keywords: program comprehension, DSL, domain-specific languages, program understandingPublished: 06.07.2017; Views: 590; Downloads: 143 Full text (248,98 KB)This document has many files!
