Chosen logistics processes in Škoda JS
No full textThis master thesis deals with the purchase and sale process in Škoda JS company. The aim of this work is to assess whether the setting of the purchase and sale process is met by the company also within a real business case, in compliance with set controls, and whether the degree of perfect delivery is sufficient. In the introduction, the author specifies the basic terms: logistics, logistic chain, customer benefits, information systems in logistics, buying and selling. The following chapter introduces Škoda JS company, including the sphere of its entrepreneurial activity. This chapter also deals with the nuclear power industry. In the crucial chapter, the author describes the process of purchase and sale in Škoda JS company and compares it with a real business case. In conclusion, the author evaluates discrepancies and suggests recommendations to avoid them
Radiocarbon age profiles and size dependency of mixing in northeast Atlantic sediments
No full textIn recent years, the most common technique for radiocarbon dating of deep-ocean sediments has been accelerator mass spectrometry (AMS) analysis of hand-picked planktonic foraminifera (forams). Some studies have exposed age offsets between different sediment size fractions from the same depth within a core and this has important implications when establishing a chronological framework for palaeoceanographic records associated with a particular sediment component.The mechanisms generating the age offsets are not fully understood, a problem compounded by the fact that the fraction defined as “large” varies between different studies. To explore this problem, we dated samples of hand-picked forams from two Biogeochemical Ocean Flux Study (BOFS) cores, for which the presence of an offset between the bulk carbonate and>150 µm foraminiferal calcite had already been demonstrated. The presence of a constant age offset between bulk carbonate and coarse fraction material at the two BOFS sites has been confirmed, but the magnitude of the offset is dependent on whether a simple size-separation technique or hand-picking of well-preserved forams is applied. This may be explained if the selection of well preserved forams biases the sample towards those specimens that have spent least time in the surface mixed layer (SML) or have undergone less size selective mixing. Modeling of the 14C profiles demonstrates that SML depth and sediment accumulation rates are the same for both the bulk and coarse sediment fractions, which is consistent with the hypothesis that size-selective mixing is responsible for the age offset
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
Meir-Keeler Type Contractions on Js-Metric Spaces and Related Fixed Point Theorems
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
Impact of skeletal divergence on oral health-related quality of life and self-reported jaw function
No full textObjective: To investigate the differences in oral health-related quality of life (OHRQoL) and self-reported jaw function between patients with hyperdivergent and normodivergent facial types. Methods: Eighty patients with a distinctively hyperdivergent facial type (mandibular plane angle greater than 2 standard deviations, or 42 degrees) and 80 controls were individually matched according to age, sex, ethnicity, and treatment stage. Data were collected using self-report questionnaires such as the Oral Health Impact Profile (OHIP-14) and Jaw Functional Limitation Scale (JFLS-8). Results: The mean age of the patients was 17.2 +/- 4.6 years (range, 12-49 years), with most (65.0%) being female and of New Zealand European origin (91.3%). Individuals with hyperdivergent facial types had higher overall and social domain scores on the OHIP-14 (p 0.05). Conclusions: Jaw function appears to be similar in individuals with hyperdivergent and normodivergent facial morphologies. However, those with hyperdivergent facial types are more likely to self-report poorer OHRQoL than are those with normal faces, especially in relation to social aspects
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
