Comparison of Javascript ES6 and its React JS library from the point of view of a beginning developer
No full textThis bachelor thesis deals with the issue of Vanilla JavaScript and its React JS library from the perspective of a beginning developer. The aim of the work is to map in detail, practically demonstrate and then compare the basic principles of selected tools Vanilla JavaScript and React JS. The work consists of three imaginary parts. After defining important terms, the author deals in the first part with the Vanilla JavaScript approach. The given part of the procedure presents important principles of pure JavaScript with the end of the part, which is an example of practical development in this tool. The second part of the work deals with the React JS library in the same way. The given part of the work goes again from the description of theoretical principles to a practical demonstration of the development of a functionally identical application, but this time from the point of view of the React JS tool. In the third and final part of the work, the author theoretically compares the key differences, advantages and disadvantages of the principles in the development of the application in Vanilla JavaScript and the React JS library. This part is then concluded with a final summary of the comparison with a detailed description of the advantages and disadvantages of each approach with a framework recommendation for the use of the solutions in various development situations. After reading the work, the reader should get a comprehensive idea of the possibilities of using the tools in solving specific problems, in such a way that they can choose the right tool in practice to solve the problem.Táto bakalárska práca sa zaoberá problematikou Vanilla JavaScriptu a jeho knižnice React JS z pohľadu začínajúceho vývojára.

3D pgRouting and visualization in Cesium JS using the integrated model of LADM and IndoorGML
No full textA web-based application has been developed, exploiting the integrated model of LADM andIndoorGML to provide indoor navigation based on the user's access rights in an educationalbuilding. Different types of users (students, teachers, visitors, etc.) have different access rights,which also depend on the exact time (e.g. inside or outside office hours). A 3D BIM IFC fileof a building has been geo-referenced and converted into a LADM complaint database inPostgreSQL/PostGIS and is enriched with information about access rights based on therelationship between users, time and indoor spaces. The PostgreSQL extension pgRouting hasbeen used for the actual routing. To support the access rights-based routing, the databasecontains several tables to represent nodes, edges, parties (users), and rights. There is one overallnetwork for the whole building, and database views are used to dynamically select the relevantnodes and edges based on the time and the user’s rights. The Dijkstra algorithm is used tocompute the shortest path. Finally, the 3D geospatial web-platform Cesium JS is used to createa client GUI allowing to specify start and destination, the user and time, and to visualize thenavigation routes. As this GUI is web-based it can run on different platforms, such as desktops,laptops, tablets and mobile phones. This paper provides a complete description of all the stepsto design, develop and test the integrated model of LADM and IndoorGML.GIS Technologi

No full textKARAPINAR, ERDAL/0000-0002-6798-3254We introduce two classes of Meir-Keeler type contractions in the framework of JS-metric spaces introduced by Jleli and Samet (2015). For each class, a fixed point result is derived. Some interesting consequences which follow from our obtained results are discussed.King Saud University (Saudi Arabia)The second author extends his appreciation to Distinguished Scientist Fellowship Program (DSFP) at King Saud University (Saudi Arabia)
Eddy-Induced Growth Rate of Low-Frequency Variability and Its Mid- to Late Winter Suppression in the Northern Hemisphere
No full textSynoptic eddy and low-frequency flow (SELF) feedback plays an important role in reinforcing low-frequency variability (LFV). Recent studies showed that an eddy-induced growth (EIG) or instability makes a fundamental contribution to the maintenance of LFV. To quantify the efficiency of the SELF feedback, this study examines the spatiotemporal features of the empirical diagnostics of EIG and its associations with LFV. The results show that, in terms of eddy vorticity forcing, the EIG rate of LFV is generally larger (smaller) in the upper (lower) troposphere, whereas, in terms of eddy potential vorticity forcing, it is larger in the lower troposphere to partly balance the damping effect of surface friction. The local EIG rate shows a horizontal spatial distribution that corresponds to storm-track activity, which tends to be responsible for maintaining LFV amplitudes and patterns as well as sustaining eddy-driven jets. In fact, the EIG rate has a well-defined seasonality, being generally larger in cold seasons and smaller in the warmest season, and this seasonality is stronger in the Northern Hemisphere than in the Southern Hemisphere. This study also reveals a mid-to late winter (January-March) suppression of the EIG rate in the Northern Hemisphere, which indicates a reduced eddy feedback efficiency and may be largely attributed to the eddy kinetic energy suppression and the midlatitude zonal wind maximum in the midwinter of the Northern Hemisphere.O (subject to Restrictions below, author can archive publisher's version/PDF)1144sciescopu
Peer Review for Journals: Evidence on Quality Control, Fairness, and Innovation
No full textI reviewed the published empirical evidence concerning journal peer review, which consisted of 68 papers, all but three published since 1975. Peer review improves quality, but its use to screen papers has met with limited success. Current procedures to assure quality and fairness seem to discourage scientific advancement, especially important innovations, because findings that conflict with current beliefs are often judged to have defects. Editors can use procedures to encourage the publication of papers with innovative findings such as invited papers, early-acceptance procedures, author nominations of reviewers, results-blind reviews, structured rating sheets, open peer review, and, in particular, electronic publication. Some journals are currently using these procedures. The basic principle behind the proposals is to change the decision from whether to publish a paper to how to publish itpeer review, journals, publications
Comment on "Wandering minds: The default network and stimulus-independent thought"
No full textMason et al. (Reports, 19 January 2007, p. 393) attributed activity in certain regions of the "resting" brain to the occurrence of mind-wandering. However, previous research has demonstrated the difficulty of distinguishing this type of stimulus-independent thought from stimulus-oriented thought (e.g., watchfulness). Consideration of both possibilities is required to resolve this ambiguity
Defining Meyer's loop-temporal lobe resections, visual field deficits and diffusion tensor tractography
No full textAnterior temporal lobe resection is often complicated by superior quadrantic visual field deficits (VFDs). In some cases this can be severe enough to prohibit driving, even if a patient is free of seizures. These deficits are caused by damage to Meyer's loop of the optic radiation, which shows considerable heterogeneity in its anterior extent. This structure cannot be distinguished using clinical magnetic resonance imaging sequences. Diffusion tensor tractography is an advanced magnetic resonance imaging technique that enables the parcellation of white matter. Using seed voxels antero-lateral to the lateral geniculate nucleus, we applied this technique to 20 control subjects, and 21 postoperative patients. All patients had visual fields assessed with Goldmann perimetry at least three months after surgery. We measured the distance from the tip of Meyer's loop to the temporal pole and horn in all subjects. In addition, we measured the size of temporal lobe resection using postoperative T1-weighted images, and quantified VFDs. Nine patients suffered VFDs ranging from 22% to 87% of the contralateral superior quadrant. In patients, the range of distance from the tip of Meyer's loop to the temporal pole was 24–43 mm (mean 34 mm), and the range of distance from the tip of Meyer's loop to the temporal horn was –15 to +9 mm (mean 0 mm). In controls the range of distance from the tip of Meyer's loop to the temporal pole was 24–47 mm (mean 35 mm), and the range of distance from the tip of Meyer's loop to the temporal horn was –11 to +9 mm (mean 0 mm). Both quantitative and qualitative results were in accord with recent dissections of cadaveric brains, and analysis of postoperative VFDs and resection volumes. By applying a linear regression analysis we showed that both distance from the tip of Meyer's loop to the temporal pole and the size of resection were significant predictors of the postoperative VFDs. We conclude that there is considerable variation in the anterior extent of Meyer's loop. In view of this, diffusion tensor tractography of the optic radiation is a potentially useful method to assess an individual patient's risk of postoperative VFDs following anterior temporal lobe resection
