Review of Automatic Passenger Counting Systems in Public Urban Transport

This paper gives an overview and analysis of the most frequently used methods and technologies as well as their designs, with which the passengers are counted on board public urban transport vehicles. It is well-known that the use of sensor technology provides added value to the already existing system, and the offered overview of various automatic passenger counting systems in public urban transport tends to show how much certain designs, methods and technologies contribute to this. Furthermore, a review has been made of the characteristics of certain technologies based on the available relevant studies in which various measurements were done regarding the accuracy, i.e. precision of certain designs. The information such as the vehicle occupancy by the number of passengers, movement of passengers at stops of public urban passenger transport (PPT) and occupancy on certain transport lines that can be achieved by using the automatic passenger counting (APC) system. The paper presents the APC system distribution, which is divided in the first step into integrated systems, where direct interaction is performed with the passengers, and independent systems or independent passenger counting, where there is no direct interaction with the passengers. The application of one or several passenger counting methods would enable more systematic management of public urban transport (PUT), thus contributing to the optimization of the transport system on the whole.

Technology transfer and foreign direct investment in the light of innovation management on the example of Poland

The Modern technology, knowledge and investment in people are nowadays important, if not the most important factors for the long-term development of enterprises. Investments in these aspects of increasing corporate value significantly determine their national competitive advantage. Not without significance in this case are the links and cooperation of domestic companies with companies with foreign capital. It is their expansion that is attributed, among others, to filling the gap of capital shortage, transfer of modern technologies, knowledge and skills or diffusion of modern organizational solutions. Therefore, the aim of this article was to identify the degree of impact of the cooperation of transnational corporations and Polish companies in the field of technology transfer. The main study was conducted in 2017 and covered a group of 120 foreign companies from the list of the largest foreign investors in Poland, drawn up by the Polish Information and Foreign Investment Agency

Design of simulation workplace for quality evaluation using LEAN principles and vision system

The very rapid development of measurement and information technology enables the use of highly intelligent systems based on digital data network communication. Companies that want to gain a competitive advantage on the market are forced to implement the latest knowledge and trends, and customer satisfaction is also a prerequisite. The customer is currently de-manding lower prices, higher quality and shorter lead times. The several systems have been developed that evaluate quality directly in the process and various online measurement systems to detect ineligible products. The aim is to eliminate the products which are not achieve the customer re-quirements These technologies make it possible to reduce company losses and allow the effective implementation of LEAN methods and tools. It is a series of methods designed to minimize the waste of material and labor while maintaining or increasing production levels. The result is a net im-provement in overall productivity and a reduction in losses due to poor quality production. The paper describes the design of an experimental workplace equipped with a camera system for monitoring the achieved quality of the production process. The principles of statistical quality eval-uation were used to assess the achieved quality. In order to eliminate the losses generated by poor quality production, the paper will propose a lean production approach. Workplace design will be created in Tecnomatix Plant Simulation

Possibilities of Using Data Envelope Analysis for Quality Management of Public Services at the Local Level

Public administration ensures decisions of elected bodies, it means governance of public issues, ensures compliance of practice with law. Public administration creates sustainable economic prosperity, ensures social cohesion and human well-being. Public administration has very often been seen as a service to the population, its quality affects not only social confidence in the public sector and the whole political system. From the economic point of view, public administration represents a managerial structure ensuring mainly the supply of public goods, the allocation function of the public sector and its ability to efficiently provide public goods and public services are particularly important. Paper describes the context of territorial public administration in the Czech Republic when all municipalities are obliged to provide basic administrative services and local public services. Public libraries and elementary schools represent traditional public service provided by communities and towns. Using the method Data envelopment analysis (DEA) the paper focuses on assessing the economic efficiency of providing those two traditional public services.

Methodology proposal for proactive detection of network anomalies in e-learning system during the COVID-19 scenario

In specific conditions and crisis situations such as the pandemic of corona-virus (SARS-CoV-2), or the COVID-19 disease, e-learning systems became crucial for the smooth performing of teaching and other educational pro-cesses. In such scenarios, the availability of e-learning ecosystem elements is further highlighted. An indicator of the importance for securing the avail-ability of such an ecosystem is evident from the DDoS (Distributed Denial of Service) attack on AAI@EduHr as a key authentication service for num-ber of e-learning users in Republic of Croatia. In doing so, numerous users (teachers/students/administrators) were prevented from implementing and participating in the planned teaching process. Given that DDoS as an anom-aly of network traffic has been identified as one of the key threats to the e-learning ecosystem in crisis scenarios, this research will focus on overview of methodology for developing a model for proactive detection of DDoS traffic. The challenge in detection is to effectively differentiate the increased traffic intensity and service requests caused by legitimate user activity (flash crowd) from the illegitimate traffic caused by a DDoS attack. The DDoS traffic detection model developed by following analyzed methodol-ogy would serve as a basis for providing further guidelines and recommen-dations in the form of response to events that may negatively affect the availability of e-learning ecosystem elements such as DDoS attack.

The Effect of non-Wi-Fi Interference on the Throughput of IEEE 802.11 based Wireless Networks

IEEE 802.11 or Wi-Fi networks are one of today's most prevalent networks. However, there is a wide array of potential sources of interference that can negatively affect the baseline expectation of every Wi-Fi network - through-put. One example is 2.4 GHz wireless sound transmitter. However, there has been a little discussion on its effect size on the throughput of Wi-Fi network despite that it is often being used in various Wi-Fi deployments. To begin to fill this gap, we have measured the effect of Line6 Relay G30 wireless sound transmitter on the throughput of IEEE 802.11 network. The measurement was performed in a laboratory environment before and during coexistence of interferer and wireless network. The results suggest that average data rates may drop up to 89%. Our findings may be useful to network professionals and practitioners in managing issues in IEEE 802.11 wireless network by providing additional insights about the effect and magnitude of this type of non-Wi-Fi interference on its throughput

Small parts recognition by convolutional neural net-works with implementation to virtual reality devices for assisted assembly tasks

The paper presents a new approach to recognize small parts from high resolu-tion 4K images grabbed by embedded camera with trained convolutional net-work models. The main principle is combination of standard machine vision techniques (OpenCV library) to identify blobs in high resolution image and parse to suitable set of ROI (region of interest), which are later recognized by trained CNN model (Tensorflow framework). The CNN with SSD (single shot detection) was selected to identify position of object. 3D virtual models of parts with autogenerated orientations are used for simpler input data generation. Two embedded devices were selected for using in the experimental system. The first is NVidia Xavier dev board with 4K camera and integrated APU and the second is Raspberry PI 4 with external APU Intel Neural Compute Stick 2. The last part of the paper shows implementation of presented principle to virtual device (HTC Vive Pro) for assisted assembly tasks to train and check workers during teaching process.

Use Cases for C-ITS Testing of Autonomous Vehicles

Autonomous vehicles seem to be an integral part of future transport, both in passenger and freight transport. One of the cornerstones of autonomous vehicles is their mutual ability to communicate. In addition to mutual communication, communication with the infrastructure is also required, and general connectivity to the Internet for obtaining data from information systems is also important. So we are talking about CAV - Connected and Autonomous Vehicles. For communication, both the speed and security of communication and the trustworthiness of the source of the message are important. Communication is important for different road situations. Currently, use cases for warning messages for drivers are being tested internationally, and the Czech Republic is also involved in this testing through the C ROADS Czech Republic project. This overview paper lists the various use cases where vehicle-to-vehicle communication or vehicle-to-infrastructure is used.

Enhancing the Aircraft maintenance management process for increasing safety

In the aircraft maintenance program, especially in the case of aircraft wheel overhaul, it is important to examine the mechanical damages such as cracks, corrosion, and some other surface irregularities and evaluate the extent of repair work. But within the finite time of maintenance procedure, it is diffi-cult to find the defects rapidly. During aircraft and its components mainte-nance ‘NON DESTRUCTIVE TESTING ‘(NDT) is the most effective way of performing inspection and discovering defects. In simply It can be told, NDT detects cracks and other irregularities in the airframe structure, wheels, en-gine components which are clearly not visible to the unclad eye. Structure and assembly of the aircraft wheels are made from various materials, such as aluminum, steel, magnesium, and composite materials. To dismantle the aircraft wheel assembly in pieces and then analyze each of the components would take a long period, so the NDT method and the selection of equip-ment must be fast and effective.

Architecture of IoT system for smart monitoring and management of traffic noise

One of the characteristics of the modern world is the rapid growth of the human population. This population growth is strongly connected with the growth of urban communities. As a result, the world is facing a problem with the increase in air and noise pollution mainly in cities, which is largely caused by road traffic. Numerous discussions are currently underway to define optimal routes for the special conditions of important traffic corridors in the Republic of Serbia. In particular, discussing the problems of their position in the vicinity of urban areas, hospitals, kindergartens, schools, cultural monuments, etc. The rapid development of wireless technologies facilitates the development and imple-mentation of IoT (Internet of Things) systems in Smart cities. A model of IoT system designed for monitoring the noise in the cities caused by the traffic is presented in this paper. The collected data are used for routing the traffic to re-duce noise in sensitive parts of the city. The system used LoRaWAN, one of the most applied Low Power Wide Area Network (LP-WAN) technologies. The system architecture is based on micro-services and MQTT protocol. Besides the system model, the variations of the Dijsktra shortest path algorithm are used to calculate alternative routes for navigating vehicles. The system model is presented by the widely accepted IoT layered system architecture.

The Benefits of Open Data in Urban Traffic Network

The importance of linking transport and traffic information in recent years has be-come a significant topic among the countries of the European Union and beyond. Authorities and decision-makers are introducing terms such as Open Data and Big Data into legal frameworks and are increasing focus on removing barriers from legal regulation on the use of data closely related to transport. This paper provides information on the application and level of use of Open Data and Big Data in Croatia, as well as a legal legislation framework that ensures the use of such data in the Republic of Croatia. Observations and findings on the amount of data available for use by third parties service providers that are strictly related to transport are presented. Based on experience from the other researches, the benefits brought by the availability of transport linked data that could be used in optimizing urban traffic network through the Big data technologies have been outlined.

Case study in Logistics: Purchase planning of goods for large retail chains, taking into account sale marketing campaigns

This article brings the solution to prevent the risks of shortages of certain goods (food items) in large retail chains, especially when these products are included in advertising campaigns with a temporary reduction in price and thus to ensure the satisfaction of customers. The purchase of such goods should be carefully planned on the basis of forecasting methods that differentiate between the sales under normal conditions and during advertising campaigns. This article points to the use of classical forecasting methods, which are applied differently in the two regimes. The results brought a significant reduction in the share of the sold-out goods compared to the period when the forecasting methodology was not imple-mented into the purchasing planning process. During the three months, which were set as testing period of this methodology, the percentage of sold-out goods selected in campaigns was decreased by 66%.

The use of telematics systems in transport and for-warding management

Recent changes in international markets have forced the development of transport and forwarding. This, in turn, increasingly forces the use of more and more advanced information systems. The article presents the idea and method of using telematics systems based on GPS in transport and forwarding. The aim of the article is to analyze telematics systems used in transport and forwarding and to propose improvements in the form of central solutions. The article is literature-empirical and based on the analysis of the publications on the subject and own research. The presented research shows the need to use a uniform central vehicle tracking system using GPS telematics systems. The essence of their use will be the centralized tool, thanks to which not only transport and forwarding companies will be able to track their cars, but also the recipients of these services. The main reason for implementation of these systems is the use of many sources of obtaining transport services (Internet, transport exchanges, transport and forwarding companies), reselling transport services to other forwarding companies (e.g. via freight exchange), dishonesty during transactions, shortening delivery times, control of drivers as well as the company operations, coordinating processes within the company that depend on transports, etc. The proposed solution of centralized tracking of GPS systems is a response to these market needs.

Mobile Picking Robots: A first study of the effects of human-robot-interactions in conventional order picking systems

Warehouses are increasingly experiencing a shortage of human resources. The first approaches to counteract this are flexible robot systems that are designed to support human workers. Mobile picking robots, i.e., robots that can pick independently in an order picking system, are increasingly used. At the moment, however, there is no suitable planning tool that sufficiently takes into account the system behavior of such hybrid picking systems. This paper investigates the influence of human-robot interaction on different aisle widths and layout variants. In addition, zoning is examined as a strategy and compared with the initial system. The paper finally shows that the need for coordinated processes and strategies in hybrid systems is even higher than it already is in conventional order picking systems.

How Frustrated are You? User Perception about Different Video Conference Quality Degradations

During the COVID-19 crisis in 2020 most of the usual activities, such as attend-ing business meetings, classes at schools, and universities, as well as social gath-erings with friends, colleagues, and family, took place on various online plat-forms. This migration has led to a globally significant increase in the number of users of video conferencing applications and thus a significant increase in the share of video traffic in total Internet traffic. Encouraged by such a situation, we became curious and motivated to explore user experiences and practices when us-ing these online meeting platforms. This paper brings the first results of a survey conducted on a sample of 541 respondents. There are three main result categories which are discussed in the paper: a) characteristics of a user environment from where the conferences are most often accessed, b) description of a typical online meeting use-case scenario, and c) user perception about different quality degrada-tions which may occur during the meeting. One of the interesting findings we un-raveled is that user Quality of Experience for video conferencing service varies depending on their role in the meeting.

Dynamic Load of Teeth of Cylindrical Worm Gear

The paper presents theoretical and practical knowledge related to analysis of dy-namic load of the individual drive elements containing worm gears. The paper de-scribes general principles of worm gear systems and methods of creation of dy-namic model of worm reducer or of an entire drive. It indicates possibilities of re-duction of dynamic load of a gear in the mode of frequent start-ups and halts of the drive. Steadily growing demands related to machine parameters are reflected in increase of dynamics of loading which are caused especially by rise of absolute or of rela-tive speed values of the individual parts in nodes of kinematic chains. Therefore, in case of machines the action of internal and external forces must be taken into account as well as dynamics of the processes occurring in them. Worm reducers are used in case of drives of a number of modern machinery of diverse technological direction, especially in mechanical engineering, construction industry, road transportation, agriculture, metallurgical engineering, chemical and food industry, consumer industry, etc. Their technical level and load capacity in a high degree determine technical, economical and operational characteristics of machines the part of which they become after assembling. Thus the need to as-sure increase of service life of worm reducers represent significant and up-to-date task. The paper should contribute to clarification of influence of dynamic load upon service life of worm reducers.

Analysis of available information and communication solutions and services for railway passenger information in the EU

Digital transformation represents an organizational and operational change in railway transport that is made possible by the integration of digital technologies and processes at all levels. One of the many possibilities it provides is the distribution of accurate and real-time information to all stakeholders in the rail system. It changed passenger habits and modernized passenger information systems on the rail network. Thanks to innovative technologies and digitalization, transport operators on the rail network can increase the accuracy of their business, predict customer preferences, but also personalize the services they offer on the market. For this reason, passenger information systems, as a service offered by transport operators to their customers, have become one of the most important items when planning a journey. These systems can be divided into systems before and during the trip. Real-time and accurate information that is displayed to passengers on various devices for accurate information is key items in these systems. All the above requires an architecture of information and communication services based on new technologies that will deliver all relevant information to end-users. This paper aims to present the functionalities of such systems to determine recommendations for the improvement of the existing system for informing passengers in rail traffic on the territory of the Republic of Croatia.

Use case: Information security risk assessment for providers of services in a virtual environment

Information and data in today's world are the most valuable assets of an organization. Every business system, and thus the information and data that are part of such system, are exposed to certain risks and threats. For this reason, organizations are forced to protect their assets. One of the key parameters that affect an organization’s exposure to risk is information security. Its goal is to protect information from threats. The information security risk management system establishes a mechanism for controlling and managing an acceptable level of risk in the organization. Selecting an appropriate risk assessment methodology allows the organization's managers to prioritize risks according to their severity or some other criteria. Given the complexity of today's information business, the Probabilistic Risk Assessment methodology has begun to be applied in information security risk assessment. By creating a use-case scenario, it is possible to conduct qualitative and quantitative risk assessments. Event trees and stable errors as part of the above methodology are used to indicate possible scenarios, as well as to find the causes of their occurrence and to model the possible failure of controls applicable to risk mitigation. This paper will present one of the use-cases of information security risk assessment using these trees. Also, their application in the conditions of a complex information system will be presented on the example of an organization in the Republic of Croatia.

Technological Assurance of Bracket-type Parts Manufacturing

Ways of intensification of complex parts machining on the modern metal-cutting equipment were proposed and clearly described. A problem-oriented classification of bracket-type parts has been developed, which based on the relationship between design and technological parameters of parts. It gives further development to the process of searching for fixture configurations for given production conditions in computer-aided design of technological equipment. The engineering method of coding bracket-type parts has been developed based on the design and technological parameters of parts and can be implemented in computer-aided fixture design systems. Structural code can be used in computer simulation of fixtures and information-retrieval systems. The necessity of intensification of bracket-type parts machining is substantiated. The progressive manufacturing process was proposed considering cutting-edge tendencies in machining and technological capabilities of the modern equipment.

Analysis of the Transport Market During the Covid-19 Pandemic Based on Freight Exchange

The road transport is the most popular mode of transport in Europe. It is not only the instrument of supporting goods for the final customers but also an important branch of economies. European road transport companies vary in terms of size, range, fleet and specialization but they all must follow new trends to resist the competitive pressure. It is even more important in times of crisis when all the en-tities must operate under new, unfamiliar yet, conditions. The recent situation with Covid-19 pandemic can also be considered as one of these critical situations especially for companies with international operations. New law regulations con-cerning border crossings, quarantines, observed slowdown in many sectors and other factors affected road transport companies. It is the challenge for managers to lead the company through the impediments of the pandemic. The purpose of the article is to present the situation on transport market in Po-land and Slovakia in directions to Germany, Italy and Spain during the Covid-19 pandemic. The article is literature-empirical and based on the analysis of the pub-lications on the subject and own research. Empirical input is based on data from two of the biggest freight exchanges in Europe. Conducted research showed considerable decline of demand for transport ser-vices in both countries and lesser fluctuations in supply of transport services.

Project Safety Management Systems of Students with 3D Game Development

One of the main directions of the modern state development is the sphere of ensuring the security of the population. New ways to improve the system of safety measures for participants in the educational process in emergencies, which provide increased stress resilience of students and provide support at a high level of their knowledge and skills to act in extreme conditions were been proposed. One of the ways is a project of training in a virtual environment close to real conditions. It is proposed, for the first time, to develop a training-game 3D simulator for psychological preparation and training of students to act in emergencies, using various functions of modeling possible emergencies. The developed software will help to increase the level of socio-economic protection of students through the game in a 3D-simulator, which will be offered to students as homework or before lessons, or as training behavior in emergencies of different nature and under different conditions.

Intangibles in Manufacturing Industry: An Empirical Analysis

We analyse the effect of firm’s intangibles in manufacturing industry ex-pressed as R&D expenses and investment in intangible assets on firm value. We used regression models, whereby R&D expenses and investment in in-tangible assets to the market capitalization of a selected group of 1092 European public listed companies are used. We found out that R&D expenses, as well as intangible fixed assets, can significantly explain market capitalization of the selected companies in manufacturing industry. We have also found out that increasing investment in the R&D causes an increase in the market capitalization. Our analysis expresses that firm with higher intangible investment tends to have higher market capitalization and that investment in intangible assets is rewarded in the form of higher intangible capital as a part of the market capitalization.

A Systematic Analysis of an Industrial Pick-Up & Placement Production System

Surface-mount technology is a method for producing electronic circuits in which the components are mounted or placed directly onto the surface of printed circuit boards. The purpose of this study was to analyze nozzle change in two produc-tion lines. Following a previous study, it was proposed that one type of nozzle would place resistors while another type of nozzle would place capacitors, contra-ry to what happened in the initial process, where the two placed both compo-nents. However, the change of nozzle was not done globally, but only applied to two specific types of capacitors that were more critical. Even so, the positive ef-fect of this change was globally visible, both in the decreased number of compo-nent rejection and in the reduced number of component defects in the printed cir-cuit boards. It was also possible to estimate the percentage saving and the ex-pected growth from this new implementation. The data were validated using sta-tistical analysis. Finally, the current cleaning periodicity of the nozzles was exam-ined in order to verify if it was compromising their performance.

Analysis of the Possibilities of Increasing the Efficiency of a Manufacturing Company through the Application of an Innovative Marketing Strategy

Marketing, very current topic. This topic is often discussed not only in media but also in companies and by ordinary people – costumers and final consumers. A lot of peo-ple see Marketing as a tool which helps us to sell the product or service. It is partly true, in modern marketing, the customer opinion is very important and it is necessary to focus on what precedes and proceed the sell, where these days the relationship be-tween a customer and the company is starting to grow. The main task of this article is to focus on modern marketing directions, which companies can manufacture and ef-fectively sell the product or service with. Also it is necessary to focus on those mod-ern marketing directions which are based on customer demands. It is very important to satisfy customers needs and this is why is necessary analyze and evaluate their re-quirements and implement them in to the production processes. Many of new modern marketing directions which raise effectivity in production and competitiveness on the market has been created because of these circumstances.

Comparison of Utilization Level of Knowledge-based and BIM Technology by Contractors in Management of Construction Projects

Knowledge technologies are one of the effective tools for process management in various industries and production. According to several researches, their implementation and use are beneficial, and this also applies to the management of construction projects. This specific sector is largely influenced by a large number of participants with sometimes conflicting interests. Nevertheless, knowledge technologies help the management process and increase the assumption of efficiency in a given sector. Knowledge systems in this area are closely connected with BIM technologies. There are several benefits to using these technologies. That is why it is important to examine their level of use and to map this phenomenon in the field of construction projects. This research is aimed at mapping the level of use of these technologies over the last two years and analyzing the trend of use in the management of construction projects. The main goal of the research is to compare the level of use of knowledge-based technologies and BIM technologies by suppliers in the management of construction companies.

Implementation of biological samples monitoring used UHF RFID technology: A concept

The focus of the presented manuscript is on the design of the concept of UHF RFID technology aimed at tracking biological samples. The purpose of the article is to point out the possibility of changing the current state when barcodes are paste to biological samples. They are then accompanied by a paper request for tests and thus sent together to the laboratory. The article is intended to serve as a proposed concept using digitization and high-frequency radio-frequency identification. The first part of the manuscript po-ints to the already established eHealth system and the still unresolved issue of eLab. This is following by an analysis of the individual elements of the concept divided into three areas and the RFID system, software and biological samples. The second chapter is focu-sing on the gradual design of components needed for the implementation of the plan. It described the individual steps from the design of specific har-dware through the progressive design of the software structure. Based on the given proposal, several conclusions were drawn, which we can assume, but their confirmation is only at the theoretical level. The presented concept is legislatively demanding, as about the GDPR, it is a matter of working with personal data on human health. As the main benefit, we can assume the de-sign of a comprehensive concept using contactless technology with mass re-ading at a distance of several meters, which is a benefit for the current epi-demiological period.
