Biomass is monitored in many agricultural studies because it is closely related to the growth of the crop. The technique of digital repeat photography that continuously capture images of a given area with an RGB or near-infrared enabled cameras, Phenocams, has been used for more than a decade mainly to estimate phenology. Studies have found a relationship between Phenocam data and above-ground dry biomass. In this context we investigate the modeling of barley fresh above and underground biomass with Green chromati...

SMOKE AND FOG CLASSIFICATION IN FOREST MONITORING USING HIGH SPATIAL RESOLUTION IMAGES

(STEF92 Technology, 2022-11-15, Julia Åhlén)

Show more

Forest fires cause major damage to human habitats and forest ecosystems. Early detection may prevent serious consequences of fast fire spread. Although there are many smoke detection algorithms employed by various optical remote sensing systems, there is still a major misdetection of images containing fog. Fog exhibits similar visual characteristics to smoke. Furthermore, when monitoring dense forests many smoke detection algorithms would fail in robust recognition due to fog covering the trees at dawn. There have...

USING IMAGE PROCESSING SOFTWARE DEVELOPED FOR B-IMAGING ON MR IMAGES BASED ON THRESHOLDING ALGORITHM IN A SELECTABLE REGION OF INTEREST

(STEF92 Technology, 2021-12-20, Jiří Blahuta, Tomáš Soukup, Jan Lavrinčík, Lukáš Pavlík)

Show more

In 2011, we developed our application for B-imaging based on binary thresholding algorithm in a selectable Region of Interest. This application has been used in many studies focused on ultrasound B-imaging in neurology; primarily for substantia nigra echogenicity examination and also for some different brain structures, e.g. mediotemporal lobe atrophy investigation. One of principal output value is an echogenicity index which is used as a marker of the echogenicity grade. Many published studies showed that is well...

VEGETATION INFLUENCE ON CANOPY HEIGHT MODELS DERIVED FROM AIRBORNE LASER SCANNING

(STEF92 Technology, 2021-12-20, Martin Zapotocky, Milan Koreň, Stanislava Vranova)

Show more

The paper examines the influence of vegetation season on canopy height models (CHM) derived from airborne laser scanning (ALS) data. ALS data were captured during the leaf-on (September 2011) and leaf-off seasons (April 2012) on the territory of the University Forest Enterprise of the Technical University in Zvolen, Slovakia. An automated procedures for deriving high-resolution digital terrain models (DTM) and digital surface models (DSM) were developed. CHM was calculated as the difference between DTM and DSM. CH...

VIRTUAL RECONSTRUCTION OF MEMORABLE PLACES ASSOCIATED WITH THE LIFE OF THE MERCHANT AND PHILANTHROPIST M.V. ASEEV ON THE TAMBOV LAND IN RUSSIA

(STEF92 Technology, 2021-12-20, В. А. Немтинов, Alexander Gorelov, Andrey Borisenko, Yulia Nemtinova, Sergei Tryufilkin)

Show more

The article deals with the issues of virtual reconstruction of memorable places associated with the life of M.V. Aseev in the Tambov province (Russia). Mikhail Vasilyevich Aseev (1858-1933) was a major Russian landowner, entrepreneur, influential industrialist and philanthropist. In 3D modeling programs (SketchUp, Blender) three-dimensional models of objects (buildings, utensils, etc.) were built according to known parameters (size, material), including both existing objects and lost or partially destroyed ones. U...

A MODEL FOR TIMELY DELIVERY OF IT SOLUTIONS FOR BULGARIAN UNIVERSITIES

(STEF92 Technology, 2020-09-20, Ivan Kuyumdzhiev)

Show more

The universities in Bulgaria operate in a very dynamic environment. The Ministry of Education and Science (MES) changes annually the requirements that their systems must meet. Changes can be small and affect only parts of the information systems in use or impose fundamental changes. To cope with this challenge, each university has a choice - either to move to a high level of digitalization or to maintain a minimum digitization of processes, so that no correction is needed in them, thus increasing the hours of work...

Show more

The efficiency of a mining enterprise depends on the quality and timeliness of management decisions. Despite the fairly high scientific, theoretical and practical levels of development of this scientific direction, the abundance of software products on the market, the issue of effective technological management remains very relevant and important. The analysis performed by the authors made it possible to establish that the weakest link in existing systems is to take into account the relationship between the parame...

Most modern software systems use dozens of traffic types, which leads to the transmission of large volumes of data of three main types via communication channels: audio, video, and computer data. Such software systems are built on the basis of multiservice computer networks in which all data is transmitted over a single communication channel, which makes it possible to use common standards and simplifies the construction of a network capable of serving a large number of users. Thanks to these features, multiservic...

APPROACH TO THE AUTOMATIC GENERATION OF RULES FOR A FUZZY CONTROLLER IN THE PROCESS OF LEARNING WITH A TEACHER

(STEF92 Technology, 2020-09-20, Jaafer Daiebel, Nikolai Sergeev)

Show more

The authors propose an algorithm for automatically constructing rules for control subsystems, which can be attributed to fuzzy regulators. Numeric variables used to obtain information about the control object and control actions by which a human operator controls the object in the work are presented in the form of linguistic variables. The membership functions of these variables are constructed as a result of an expert survey. The example describes the operation of the simplest odd regulator with readymade rules. ...
