Only the main sealing part, filled with glass paste, in which the image is engraved, has been preserved from the object. The thin ring soldered to the tile is not preserved. The traces from the solder of the ring to the solder on the reverse side of the board are clearly visible. The latter has an elliptical shape with a scalloped outline and bud-like ornamentation above it. The central part of the object is occupied by a deep socket filled with greenish glass paste, in which the image of the heraldic lily is carved. Rings with images of lilies from the late Middle Ages are a whole group, and therefore this type of decoration can be considered one of the favorites of this period. Most of the ornaments are made entirely of metal, the more famous ones being silver and gold. The symbolic meaning of the lily is a reason for it to appear on various art monuments, such as the portraits of the founders from the church "St. Nicholas" in Stanichane (XIV century), the late medieval belts with appliqués in the shape of lilies from the territory of Bulgaria and many others . In this context, we can also place the current ring with an engraved image of a heraldic lily from the era of the Second Bulgarian Kingdom, found in the vicinity of Shumen and the Shumen Fortress, whose most active life was precisely during this period.</p> 2024-11-12T00:00:00+02:00 Copyright (c) 2024 JOURNAL SCIENTIFIC AND APPLIED RESEARCH https://jsar.ftn.shu.bg/index.php/jsar/article/view/390 DETERMINATION OF AN OBVIOUS FACTUAL ERROR IN A CADASTRAL MAP 2024-11-12T19:38:40+02:00 Mirem Niyazi-Yusuf m.niyazi@shu.bg Krasimira Kirilova k.kirilova@shu.bg Kiril Yanchev k.yanchev@shu.bg <p>The maps created of reinstated property after 1990 contain numerous errors. These errors have been transferred from the existing cadastral plans, comassation plans, land subdivision plan, aerial photo plans and a large-scale topographic maps created in the years 1964-1968. For the creation of maps of the reinstated property, the sources described above were used directly, without repeated aerial photography or deciphering of the objects as well as without the conduction of&nbsp; direct geodetic measurements [6, 8].&nbsp;The presence of an obvious factual error is a relatively common phenomenon in the cadastral map. The same applies mainly to linear objects and it is quite possible to remove these errors. These errors can be corrected via separate projects for the specific errors, as well as via projects affecting a large part of land territory and even an entire land territory.</p> 2024-11-12T00:00:00+02:00 Copyright (c) 2024 JOURNAL SCIENTIFIC AND APPLIED RESEARCH https://jsar.ftn.shu.bg/index.php/jsar/article/view/388 ACOUSTIC WAVES – SONAR EQUATION 2024-11-12T11:40:26+02:00 Evgeni Stoykov e.stoykov@shu.bg <p>The earliest methods used to directly measure water depth were the guide line (lead line) and drilling.

Ethernet is one of the most popular networks, especially if equal access networks are to be built and maintained. Ethernet is widely used to control machines, production lines and even entire production plants. However, working in real-time mode sometimes creates conflicts in certain actuators which are time-sensitive to the commands sent to them. Therefore, it is necessary to investigate the average delay time and time dispersion of the LAN Ethernet, to be able to meet the requirements for real-time operation in logistics.</p> 2023-11-29T00:00:00+02:00 Copyright (c) 2023 JOURNAL SCIENTIFIC AND APPLIED RESEARCH https://jsar.ftn.shu.bg/index.php/jsar/article/view/381 A DISTRIBUTION SYSTEM DESIGN MODEL 2023-11-29T23:00:19+02:00 Andrey Bogdanov a.bogdanov@shu.bg <p>Large varieties of mathematical programming models have been developed to provide decision support to the design engineer.

According to the UN Economic Commission for Europe (ECE) 2006 Report on the 1968 Geneva Convention "Road Signs and Signals", the rules are periodically updated to take into account the growing demands for human safety, environmental protection, and the rapid development of technological progress around the world (Report IEC UN, New York and Geneva, 2007). Unfortunately, for about a hundred years now, no drastic measures have been taken against the causes of road traffic accidents around the world. Our research is focused on reducing intersection congestion, traffic accidents, and related deaths. A new road sign and traffic light were invented. According to the conclusions of domestic and foreign scientists, the invented sign and traffic light should be a great success in practice.</p> 2023-11-29T00:00:00+02:00 Copyright (c) 2023 JOURNAL SCIENTIFIC AND APPLIED RESEARCH https://jsar.ftn.shu.bg/index.php/jsar/article/view/379 STUDYING THE APPLICATION OF CAD/CAM/CAE SYSTEMS IN THE DESIGN OF COMPONENTS FOR PERSONAL BALLISTIC PROTECTION EQUIPMENT 2023-11-29T22:33:47+02:00 Stamen Antonov STAMANTONOV@ABV.BG Mariela Ivanova M.L.IVANOVA@SHUV.BG <p>The article presents a study of the possibilities for applying the virtual set of tools for 3D modeling, manipulation, and testing of components that are part of individual ballistic protection equipment.</p> 2023-11-29T00:00:00+02:00 Copyright (c) 2023 JOURNAL SCIENTIFIC AND APPLIED RESEARCH https://jsar.ftn.shu.bg/index.php/jsar/article/view/378 INVESTIGATING THE NETWORK TRAFFIC USING THE COMMAND-LINE PACKETS SNIFFER TCPDUMP IN KALI LINUX 2023-11-29T22:25:35+02:00 Petar Boyanov petar.boyanov@shu.bg <p>In this scientific article a comprehensive investigation of the network traffic using the command-line packets sniffer Tcpdump in kali Linux is made.</p> 2023-11-29T00:00:00+02:00 Copyright (c) 2023 JOURNAL SCIENTIFIC AND APPLIED RESEARCH https://jsar.ftn.shu.bg/index.php/jsar/article/view/377 BASIC NETWORK PENETRATION TESTING WITH THE NETWORK TOOL NETCAT IN LINUX-BASED OPERATING SYSTEMS 2023-11-29T21:37:19+02:00 Petar Boyanov peshoaikido@gmail.com <p>In this scientific article a basic network penetration testing with the network tool Netcat in Linux-based operating systems is presented.</p> 2023-11-29T00:00:00+02:00 Copyright (c) 2023 JOURNAL SCIENTIFIC AND APPLIED RESEARCH https://jsar.ftn.shu.bg/index.php/jsar/article/view/376 ON THE CULTURAL AND HISTORICAL HERITAGE OF SHUMEN FROM THE XIX CENTURY AND ON THE ECONOMIC AND TECHNOLOGICAL INNOVATIONS IN THE CITY 2023-11-29T21:25:14+02:00 Milena Georgieva m.a.georgieva@shu.bg <p>During the period XV – XIX century, Shumen was an important administrative center in the Ottoman Empire because of its strategic location, favorable weather and its natural defenses.

A comparison was made with a control group of healthy individuals from the modern Bulgarian population. The distribution of the blood groups in the sample was different from that of the control group (p &lt;0.001). There was a significant increase in the prevalence of persons with blood group B (p &lt;0.001), and a significant decrease in groups 0 (p &lt;0.001) and A (p &lt;0.05). In group AB, a slight increase in frequency was detected. With respect to the Rhesus factor, there was an increase in the patients with positive Rhesus factor - by 9.23% to 93.94% (p&lt;0.05).
