In this paper, we present the collection and mining of GitHub data, aiming to understand GitHub user behavior and project success factors. We collected information about approximately 100K projects and 10K GitHub users//owners of these projects, via GitHub API. Subsequently, we statistically analyzed such data, discretized values of features via k-means algorithm, and finally we applied apriori algorithm via weka in order to find out association rules. Having assumed that project success could be measured by the cardinality of downloads we kept only the rules which had as right par a download cardinality higher than a threshold of 1000 downloads. The results provide intersting insight in the GitHub ecosystem and seven success rules for GitHub projects.

A geometric path from s to t is increasing-chord, if while traversing it from s to t the distance to the following (resp. from the preceding) points of the path decreases (resp. increases). A geometric graph is increasing-chord if each two distinct vertices are connected with an increasing-chord path. We show that given a convex point set P in the plane we can construct an increasing-chord graph consisting of P, at most one Steiner point and at most 4|P| - 8 edges.

The SIMPATIC project (acronym for Intelligent System for the Private and Autonomous Surveillance based on Information and Communication Technologies, in Catalan) addresses the building of a monitoring system for people affected with Mild Cognitive Impairments (MCI). It consists of a mobile app running on the patient's smartphone and a server that analyses the device's location and raises alarms under certain conditions. This is a research project that comprises both technological and human challenges. Regarding the technological aspects, we have not merely built a testbed prototype: our technology has been tested in a real-life scenario. In this paper we address the implementation aspects and technological results of the pilot test conducted within the SIMPATIC project. We describe the architecture of the SIMPATIC system as well as its functionalities, but we focus on the implementation aspects that make our software a fully functional monitoring system based on smartphones and web technology.

Ant Miner is the application of Ant Colony Optimization algorithm in data classification problem. Since it was proposed by Parpinelli et al., in 2001, a lot of data classification studies were performed with the aid of this algorithm. Also a lot of comparisons were performed between the results obtained with this algorithm and the results obtained by improved Ant Miner algorithms. Usually, in different studies different values were chosen for the input parameters such as the number of ants, the minimum number of instances covered by each rule, and so on. So we ask the question how to choose the values of input parameters in order to obtain good results for output parameters like prediction accuracy, the number of discovered rules and the execution time? In this paper we run on 15 datasets obtained from UCI Machine Learning Repository a number of 32 combinations of input parameters, and we try to find connections between the values of the input parameters and the obtained results. Finally we wrote a set of remarks regarding Ant Miner parameters, which may be useful in choosing input parameters in different studies in order to obtain overall good results. Before starting the experiments we performed a small modification to the Ant Miner open source code in order to assure that each run will work with the same subsets of data, for a fair comparison of results.

In recent years the concept of Zero Energy Building (ZEB) has attracted international interest and has led to the beginning of a new generation of buildings. There is a worldwide attempt to define the concept of ZEB and specify a methodology of modeling its operation. Defining the parameters that should be taken into consideration and classifying ZEBs helps that attempt. Energy management and intelligent control are playing a key role in the successful operation of a ZEB, improving its performance and reducing its consumption. The method of Fuzzy Cognitive Maps (FCMs) is appropriate for problems with many parameters, where mathematical modeling and calculations have difficult or, in some cases, impossible solution. ZEB is a complex system and therefore it should be as "intelligent" as possible and the use of FCMs in ZEB operation modeling is a very promising field.

A prototype of sailboat routing system for least-time navigation is presented. The routing algorithm is based on an exact graph-search method, not requiring subjective optimization parameters. The temporal variation of wind fields during the sailing time is accounted for. The system also considers topological constraints such as coastline and shallow waters. The sailboat is modelled in terms of its polar plot. Wind forecasts from multiple providers are accepted as an input. Case studies show that the algorithm consistently computes tacking, jibing, and other route diversions functional to the maximum exploitation of the sailboat performance, as provided through its polar plot. The present version of the system targets races with path lengths in the range of tens of nautical miles or more.

Recent advances in aerial photography enabled cadastrates of several countries to proceed to the cartography of rural areas and record existing forestry, farming yards, plane fields and registered land ownerships. Efforts are being made to expand this project to urban areas as well, where the main object of interest apart from land itself are the buildings themselves. The main difficulty with buildings is that they are 3D objects and additional to their planar expansion there is also their height that is of significance as well. This paper aims to comprise planar information obtained through features' extraction from ortho-open aerophotographs with vertical information obtained using terrestrial laser scanning to produce three dimensional models of multiple neighboring building blocks in an urban area. Results from the application of the proposed approach to the historic 1866 square in Chania, Greece, demonstrate both the capabilities and difficulties associated with such an attempt and derive useful conclusions for future advancements that can lead to valuable topographical urban three dimensional mappings.

Nowadays, plenty of simulation techniques based on deterministic methods like Ray Tracing and Ray Launching, combining Geometric Optics and Uniform Theory of Diffraction, are used to predict waves' behaviour within a defined environment and to make better decisions on the deployment of antennas for particular purposes. However, simulations' quality largely depends on the number of rays, providing sufficient angular resolution in the ray launching process. The computational cost of simulations in high definition (HD) prevents their use in complex environments and their low definition (LD) counterparts are used. In this article we propose a technique based on collaborative filtering (CF) to lessen the low quality problems of LD simulations. Such technique outperforms previous works in this field in terms of accuracy, precision and computational cost. Moreover, we show that our approach obtains results very similar to those of HD in much less time. Therefore, using combined deterministic-CF techniques allows the estimation of radio-planning tasks in large, complex medical scenarios with a potentially large amount of transceivers.

With the evolution of technology, social media and mobile devices, digital games have become a frequent form of entertainment for many people. As games can provide a fun environment, where students can actively learn content through actions and decisions, there are high hopes that game-based learning can be used both in and outside the classroom and yield positive learning outcomes. The aim of this study is to evaluate the effectiveness and enjoyment of a game created for art history learning, on adults of various ages, with a different art history background and game experience and to hopefully help educational game creators get closer to a balance between fun and learning.
