The high reliance on the Internet observed recently makes the quests of mobile networks capacity demand and reliability crucial in mobile networks design and management. The next generation mobile networks is anticipated to address the problem of increasing capacity demand by employing various techniques such as Massive MIMO, Heterogeneous Networks (HetNets), and millimeter wave (mm-Wave). Nevertheless,...
Free/Open Source Software developers come from a myriad of different backgrounds, and are driven to contribute to projects for a variety of different reasons, including compensation from corporations or foundations. Motivation can have a dramatic impact on how and what contribution an individual makes, as well as how tenacious they are. These contributions may align with the needs of the developer,...
This paper presents a new topology of multilevel converter that allows to increase the number of output voltage levels reducing the numbers of semiconductors necessary in comparison with the standard multilevel converters like Active Neutral Point Clamped (ANPC) and Stacked Multicell Converter (SMC). This new topology called Reduced Multilevel Converter (RMC) consists of a tandem connection of basic...
In this study, a system has been developed to provide meaning and classification of e-mails according to their contents. The aim of the work is to develop an intelligent inbox to assist in awareness of information security. In the designed system, a client is developed that can connect to the server and receive e-mails. A two-step analysis is performed on the received e-mails. For both stage analysis,...
In teleoperation of heavy machines, work efficiency will be 50% lower than manned operation because operators cannot obtain effective information about work sites due to the limitation of current monitoring systems. Operators would have opportunities to obtain such information before work (about a week required to introduce teleoperation systems) and during work. As a fundamental study to support...
Edutainment systems' Development is well documented in research papers, and its application has satisfying results in several knowledge areas. However, methods for multidisciplinary team management in immersive edutainment systems engineering were not found in the survey made. A qualitative evaluation of immersive edutainment systems' engineering was conducted aiming to achieve grounded theory that...
Virtual content on optical see-through head-mounted displays (OST-HMDs) appears dim in bright environments. In this paper, we demonstrate how a liquid crystal (LC) filter can be used to dynamically increase the perceived brightness of the virtual content. Continuously adjusting the LC filter opacity attenuates the real scene and increases the perceived brightness without being noticed by the user...
We consider properties of edge-colored vertex-ordered graphs} – graphs with a totally ordered vertex set and a finite set of possible edge colors – showing that any hereditary property of such graphs is strongly testable, i.e., testable with a constant number of queries. We also explain how the proof can be adapted to show that any hereditary property of two-dimensional matrices...
A tight criterion under which the abstract version Lovász Local Lemma (abstract-LLL) holds was given by Shearer [41] decades ago. However, little is known about that of the variable version LLL (variable-LLL) where events are generated by independent random variables, though variable- LLL naturally models and is enough for almost all applications of LLL. We introduce a necessary and sufficient...
This showpiece will present iSnap, an extension of the block-based, novice programming environment Snap!, which supports struggling students by providing on-demand hints and feedback that help them complete programming assignments. iSnap extends the existing syntactic scaffolding offered by block-based programming to additionally support the implementation of programming tasks. Research on iSnap has...
Nowadays, social networks, whose application areas are increasing day by day; Such as data mining, protein-gene interaction networks, online social networks, transport networks, academic information networks, and telecommunications networks. Many real-world complex networks have a naturel bipartite structure. In bipartite networks, which have become the focus of many researchers who have been dealing...
The new concept of manufacturing, called as Industry 4.0, must transform the paradigm of the industries much faster than any other technological revolution known at the moment. This new paradigm must require the intensive use of different machines, mechatronic systems and electronic devices that will be integrated through protocols which must allow a wide sharing of data among the devices that compose...
In this paper, we propose BoostHand, a freehand, distance-free object-manipulation system that supports simple trigger gestures using Leap Motion. In AR classrooms, it is necessary to allow both lecturers and students to utilize virtual teaching materials without any spatial restrictions, while handling virtual objects easily, regardless of distance. To provide efficient and accurate methods of handling...
Heart sounds are difficult to interpret because a) they are composed by several different sounds, all contained in very tight time windows; b) they vary from physiognomy even if the show similar characteristics; c) human ears are not naturally trained to recognize heart sounds. Computer assisted decision systems may help but they require robust signal processing algorithms. In this paper, we use a...
More email is opened on mobile devices today than on other platforms [1]. At the same time, enterprises are constantly investing in approaches to improve employee productivity. In this paper, we consider the problem of automated information suggestions to assist in reply construction. The basic premise of the work is that a significant portion of the information content of a reply is likely to be...
Content-Centric Networking (CCN) is a recently proposed Internet paradigm that focuses on scalable, secure and efficient content distribution. The main abstraction is named and addressable content. A consumer requests desired named content by generating a so-called interest, which is then routed by the network towards an in-network cached copy, or the authoritative producer, of that content. Since...
Development of document processing systems is considered. The direction of transition to the object-associated electronic document management systems is shown. The assessment of correlation of control of processes of relocation of documents and change of objects in the distributed large-scale systems is carried out.
In this paper we present a new, very large, rich, Comprehensive Scholarly Corpus (CompScholarCorp) as a platform and data source for future research. Our corpus contains records of 1,044,454 papers, 472,365 unique authors, and substantial publication meta-data for each record. We have integrated the data we collected from 276 publishers using a uniform and consistent XML data format within the corpus...
Stackelberg security games are represented by a Stackelberg model for multiple defenders and attackers. The dynamics of the game involves defenders trying to allocate their limited resources to defend important targets, and attackers observing the behavior of the defenders, look for the most advantageous target to harm. The computation of the equilibrium point is a fundamental issue for Stackelberg...
Research in the area of internet-of-things, cyberphysical-systems, and smart health often employ sensor systems at residences for continuous monitoring. Such research-oriented residential monitoring systems (RRMSs) usually face two major challenges, long-term reliable operation management and validation of system functionality with minimal human effort. Targeting these two challenges, this paper describes...
