Public speaking as a part of police directorates head's activities

The fact is that a manager who is characterized by a confident attitude and clear speech will more easily gain the trust of both subordinates and superiors, because in such a way he will convince them of his knowledge and expertise. In this paper, special emphasis has been placed on the complexity of public speaking of the police directorates heads and the importance of preparation for high-quality public speaking. The paper starts from the fact that overcoming the fear of public speaking can contribute to its improvement. It is evident that the police directorates heads have the fear of public speaking, which has strong manifestations that prevent them from achieving the purpose of their speech. On the basis of content analysis, it can be concluded that the police directorates heads can overcome the fear of public speaking by strengthening their self-confidence; by setting realistic expectations; controlling their thoughts and focusing on the topic, meaning and function of performance; visualization; preparation and practice; maintaining contact with the audience; knowing and checking the equipment used during public speaking. It can be concluded that mastering the skills of public speaking will enable a manager to get rid of the fear of public speaking and thus improve his performance. At the same time, it will enable him to be more confident in other fields of management, while constantly enhancing his organizational and managerial qualities.

Thermal Performance Visualization Using Object−Oriented Physical and Building Information Modeling

This study demonstrates the research and development of a visualization method called thermal performance simulation. The objective of this study is providing the results of thermal performance simulation results into building information modeling (BIM) models, displaying a series of thermal performance results, and enabling stakeholders to use the BIM tool as a common user interface in the early design stage. This method utilizes a combination of object-oriented physical modeling (OOPM) and BIM. To implement the suggested method, a specific BIM authoring tool called the application programming interface (API) was adopted, as well as an external database to maintain the thermal energy performance results from the OOPM tool. Based on this method, this study created a prototype called the thermal energy performance visualization (TEPV). The TEPV translates the information from the external database to the thermal energy performance indicator (TEPI) parameter in the BIM tool. In the TEPI, whenever BIM models are generated for building design, the thermal energy performance results are visualized by color-coding the building components in the BIM models. Visualization of thermal energy performance results enables non-engineers such as architects to explicitly inspect the simulation results. Moreover, the TEPV facilitates architects using BIM as an interface in building design to visualize building thermal energy performance, enhancing their design production at the early design stages.

Multimode Operating Performance Visualization and Nonoptimal Cause Identification

In the traditional performance assessment method, different modes of data are classified mainly by expert knowledge. Thus, human interference is highly probable. The traditional method is also incapable of distinguishing transition data from steady-state data, which reduces the accuracy of the monitor model. To solve these problems, this paper proposes a method of multimode operating performance visualization and nonoptimal cause identification. First, multimode data identification is realized by subtractive clustering algorithm (SCA), which can reduce human influence and eliminate transition data. Then, the multi-space principal component analysis (MsPCA) is used to characterize the independent characteristics of different datasets, which enhances the robustness of the model with respect to the performance of independent variables. Furthermore, a self-organizing map (SOM) is used to train these characteristics and map them into a two-dimensional plane, by which the visualization of the process monitor is realized. For the online assessment, the operating performance of the current process is evaluated according to the projection position of the data on the visual model. Then, the cause of the nonoptimal performance is identified. Finally, the Tennessee Eastman (TE) process is used to verify the effectiveness of the proposed method.

POSSIBILITIES OF USING WEB-TECHNOLOGIES FOR VISUALIZATION OF DATA OF ACTIVE METHODS OF REMOTE SENSING

An increasing number of types of spatial data is possible to display and operate using only technical means of web services and a standard browser, without the need to install GIS or CAD systems. One of these types of data is data obtained with using active methods of remote sensing (as a rule, they are point clouds), full-fledged work with which 3–4 years ago was possible only on high-performance computers and specialized software. The existing web technologies allow not only displaying point clouds, but also interactively interacting with them - to perform measurements, customize display styles, combine with spatial data of other types. The purpose of the article is to form criteria and analyze the performance of software tools for creating web services for visualizing data obtained with using active methods of remote sensing. For practical testing of the selected software and analysis according to the formulated system of criteria groups, several files containing point clouds from open sources were used. The research was carried out with using the software libraries Three.js, Deck.gl, Plas.io, Potree, CesiumJS and Blend4Web. Based on the testing results, summary tables of performance and functionality were formed. The obtained results demonstrate that in terms of performance, visualization tools, basic functions for designing and analyzing point clouds, modern web services are not inferior to specialized desktop software.
