High resolution digital 3D modelling of subsurface morphological structures of Koutouki Cave, Greece

Remote sensing techniques and laser scanning technology have given us the opportunity to study indoor environments, such as caves, with their complex and unique morphology. In the presented case study, we used a handheld laser scanner for acquiring points with projected coordinate information (X, Y, Z) covering the entire show cave of Koutouki; including its hidden passages and dark corners. The point cloud covers the floor, the walls, and the roof of the cave, as well as the stalactites, stalagmites and the connected columns that constitute the decoration of the cave. The absolute and exact placement of the point cloud within a geographic reference frame gives us the opportunity for three-dimensional measurements and detailed visualization of the subsurface structures. Using open - source software, we managed to make a quantification analysis of the terrain and generated morphological and geometric features of the speleothems. We identified 55 columns by using digital terrain analysis and processed them statistically in order to correlate them to the frame of the cave development. The parameters that derived are the contours, each column height, the speleothem geometry and volume, as well as the volume of the open space cavity. We argue that by the demonstrated methodology, it is possible to identify with high accuracy and detail: the geomorphological features of a cave, an estimate of the speleogenesis, and the ability to monitor the evolution of a karstic system.Key words: cave, laser scanner, 3D representation, speleothems, SLAM.  Visokoločljivostno digitalno 3D modeliranje podzemeljskih morfoloških struktur v jami Koutouki, Grčija Daljinsko zaznavne tehnologije in laserji nam omogočajo raziskovanje zaprtih prostorov, kot so jame z njihovo kompleksno in edinstveno morfologijo. Za pridobivanje različno dostopnih podatkov v turistični jami Koutouki smo v študiji uporabljali ročni laserski skener. Točkovni oblak pokriva tla, stene in strop jame ter stalaktite, stalagmite in stebre, ki prispevajo k okrasju jame. Natančna postavitev točkovnega oblaka v referenčnih geografskih okvirjih daje možnost tridimenzionalnih meritev in podrobne vizualizacije struktur v podzemlju. S podrobno analizo terena smo opredelili 55 stebrov in jih uvrstili v okvir razvoja jame. Pridobljeni so bili podatki o strukturiranosti, višini vsakega stebra, obliki in prostornini tamkajšnjih siginih tvorb ter prostornini prostega jamskega prostora. Z uporabljeno metodologijo je torej mogoče podrobno in z veliko natančnostjo opredeliti geomorfološke značilnosti jame, predvideti potek speleogeneze in spremljati razvoj kraškega sistema.Ključne besede: jama, laserski skener, 3D prikaz, sigine tvorbe, SLAM

What Drives Students' Loyalty-Formation in Social Media Learning Within a Personal Learning Environment Approach? The Moderating Role of Need for Cognition

Our study analyzes an educational experience based on the integrated use of social media within a higher education course under a personal learning environment approach and investigates the factors that determine students' loyalty to social media learning. We examined the moderating role of need for cognition (NFC) in students' formation of attitudes, satisfaction, and loyalty toward this learning experience. The results indicate that NFC has an influence on these variables, significantly moderating how loyalty toward social media learning is formed. For high-NFC students, satisfaction with the learning experience is the most important variable to explain loyalty; whereas for low-NFC students, attitudes have a stronger effect. Different strategies are suggested, according to the learners' NFC levels, for increasing the use of social media in personal learning environments. Practical implications for improving the integration of such informal resources into formal education are discussed.Junta de Andalucía – Programa Andaluz de I + D P12 SEJ 259

KM Maturity Factors Affecting High Performance in Universities

This paper aims to measure Knowledge Management Maturity (KMM) in the universities to determine the impact of knowledge management on high performance. This study was applied on Al-Quds Open University in Gaza strip, Palestine. Asian productivity organization model was applied to measure KMM. Second dimension which assess high performance was developed by the authors. The controlled sample was (306). Several statistical tools were used for data analysis and hypotheses testing, including reliability Correlation using Cronbach’s alpha, “ANOVA”, Simple Linear Regression and Step Wise Regression.The overall findings of the current study suggest that KMM is suitable for measuring high performance. KMM assessment shows that maturity level is in level three. Findings also support the main hypothesis and it is sub- hypotheses. The most important factors effecting high performance are: Processes, KM leadership, People, KM Outcomes and Learning and Innovation. Furthermore the current study is unique by the virtue of its nature, scope and way of implied investigation, as it is the first comparative study in the universities of Palestine explores the status of KMM using the Asian productivity Model

Evaluating the Relationship Between Running Times and DNA Sequence Sizes using a Generic-Based Filtering Program.

Generic programming depends on the decomposition of programs into simpler components which may be developed separately and combined arbitrarily, subject only to well- defined interfaces. Bioinformatics deals with the application of computational techniques to data present in the Biological sciences. A genetic sequence is a succession of letters which represents the basic structure of a hypothetical DNA molecule, with the capacity to carry information. This research article studied the relationship between the running times of a generic-based filtering program and different samples of genetic sequences in an increasing order of magnitude. A graphical result was obtained to adequately depict this relationship. It was also discovered that the complexity of the generic tree program was O (log2 N). This research article provided one of the systematic approaches of generic programming to Bioinformatics, which could be instrumental in elucidating major discoveries in Bioinformatics, as regards efficient data management and analysis

The chapter explains what is, and what is not, new about credibility in the context of digital media, and discusses the major thrusts of current credibility concerns for scholars, educators, and youth

A Survey on Multisensor Fusion and Consensus Filtering for Sensor Networks

Multisensor fusion and consensus filtering are two fascinating subjects in the research of sensor networks. In this survey, we will cover both classic results and recent advances developed in these two topics. First, we recall some important results in the development ofmultisensor fusion technology. Particularly, we pay great attention to the fusion with unknown correlations, which ubiquitously exist in most of distributed filtering problems. Next, we give a systematic review on several widely used consensus filtering approaches. Furthermore, some latest progress on multisensor fusion and consensus filtering is also presented. Finally, conclusions are drawn and several potential future research directions are outlined.the Royal Society of the UK, the National Natural Science Foundation of China under Grants 61329301, 61374039, 61304010, 11301118, and 61573246, the Hujiang Foundation of China under Grants C14002 and D15009, the Alexander von Humboldt Foundation of Germany, and the Innovation Fund Project for Graduate Student of Shanghai under Grant JWCXSL140
