Empowering Agribusiness with Simplicity: Web-based Artificial Intelligence Software Platform for Remote Sensing
Authors: Costa Ronaldo Martins da , Costa Lucas Matsuno da , Kai Priscila Marques , Neto Waldemiro A. Silva
Published: July 2023

Remote sensing techniques using satellite imagery are widely applied in
various fields of agricultural sciences due to the ease of obtaining
real-time information, enabling data acquisition from a region without
the need for physical displacement, thus avoiding costs. It also allows
for the exploration of more efficient methods for crop monitoring tasks.
This article presents a software platform that collects images from
publicly available sources on the internet, groups these images by
category and geographic region, and allows for the application of
different artificial intelligence algorithms for image classification.
The experiments conducted achieved an accuracy of 89.54% for the Random
Forest (RF) classifier. A neural network with three hidden layers and
one output layer achieved an accuracy of 86.66%. It is believed that
the lower performance is related to the small number of samples used for
training the network. The results demonstrate the potential benefits
involved in applying this platform in precision agriculture, considering
the ability to acquire, organize, and apply artificial intelligence to
image classification.
Do actions structure auditory memory? Action-based event segmentation effects on sensory responses, pupil dilation and sequential memory
Authors: Font-Alaminos Marta , Paraskevoudi Nadia , Costa-Faidella Jordi , SanMiguel Iria
Published: July 2023

Our actions shape our everyday experience: what we experience, how we
perceive and remember it, is deeply affected by how we interact with the
world. Performing an action to deliver a stimulus engages
neurophysiological processes which are reflected in the modulation of
sensory and pupil responses. In this study, we hypothesized that these
processes shape memory encoding, parsing the experience by grouping
self- and externally-generated stimuli into differentiated events.
Participants encoded sound sequences, in which either the first or last
few sounds were self-generated and the rest externally-generated. We
tested recall of the sequential order of sounds that had originated from
the same (within event) or different sources (across events). Memory
performance was not higher for within event sounds, suggesting that the
memory representation was not structured by actions. However, during
encoding, we replicated the well-known electrophysiological response
attenuation, together with increased pupil dilation for self-generated
sounds. Moreover, we found that at the boundary between events,
physiological responses to the first sound originating from the new
source were determined by the direction of the source switch. The
results suggest that introducing actions, acts as a stronger contextual
shift than removing them, despite not directly contributing to memory
performance. The findings contribute to our understanding of how
interacting with sensory input shapes our experiences, by addressing the
unexplored relationships between action effects on sensory responses,
pupil dilation and memory encoding, and discarding a meaningful
contribution of low-level neurophysiological mechanisms associated to
action execution in the modulation of memory.

Numerical investigation of turbulent kinetic energy and heat transfer performance of high-power-density permanent magnet synchronous motor
Authors: Zhang Jiacheng , Ge Baojun , Zhang Haixu
Published: July 2023

In the field of permanent magnet synchronous motors (PMSM) cooling, turbulent kinetic energy (TKE), and turbulent dissipation are used for the first time to numerically evaluate the heat transfer performance of axial water jackets, in order to investigate the influence of the water jackets structural parameters on the water-cooled system of high-power-density PMSM (HPD-PMSM). In the present work, the temperature distribution and fluid-flow pattern of a 40 kW HPD-PMSM were calculated using the finite element method, and temperature testing of the HPD-PMSM at different speeds using a built test platform. In addition, the effects of the bend shape of cooling channels (BSCC) on the axial water jackets performance for heat transfer are examined, and a detailed analysis of the mechanism underlying the development and evolution of high vorticity vortex is provided. The findings demonstrate that the TKE is attenuated by the positive vortex development, which is harmful to the TKE normal function in axial water jackets heat transfer. Furthermore, the maximum stator winding temperature was reduced to 93.49?C and the maximum flow velocity within the water jackets could be increased by 14.34% owing to the BSCC improvement.

Published: July 2023

Thermo-chemical conversion of cigarette butt filters (CBF) waste was investigated using various thermal analysis techniques (simultaneous TG-DTG-DTA and DSC methods) at different heating rates in an inert atmosphere. Thermo- and thermo-physical properties of waste material were discussed, from the point of view of chemical structure and the influence of experimental parameters on the conversion process. It was established that acetyl groups of plasticizer (triacetin) interact with cellulose acetate through dipolar interactions and hydrogen bonding?s. Influence of these polar interactions can affect the position of glass transition temperature, Tg, of CBF. Based on estimated value of Tg from DSC analysis, it was found that cellulose acetate present in CBF has degree of substitution equals to 2.8, where the presence of cellulose triacetate was confirmed. It was assumed that an increase of degree of substitution leads to decline in the crystallinity. A decline of crystallinity causes the reduction of hydroxyl groups, leading to less organized chains, and whereby decreasing of inter-molecular interactions through hydrogen bonding. Based on the examination of thermophysical characteristics of the tested material, it was found that both, the heat capacity and the thermal inertia of material linearly increase with temperature, during pyrolysis progression. It was concluded that the type of bio-char produced in this process would have a large capacity to store the heat, which may depend on the formed particles size diameter and porosity. Furthermore, it was inferred that magnitude drops of thermal conductivity, ?, after Tg depends on the material fibrillation.
Do Gender-Diverse Boards Enhance the Linguistic Features of Corporate Financial Reporting?
Authors: Ben-Amar Walid , García-Meca Emma , Francoeur Claude , Martínez-Ferrero Jennifer
Published: July 2023

SYNOPSIS

Textual features, such as readability and disclosure tone, of mandatory financial reports have significant economic consequences. Managers and directors’ demographic attributes can also lead to different reporting styles. This study examines how gender-diverse boards influence the readability and tone of corporate financial disclosures under the framework of upper echelons theory. Using a sample of 3,085 U.S. firm-year observations from 2007 to 2016, we find that gender diversity in the board and audit committee enhances the readability of narrative disclosures and is associated with a less optimistic, litigious, and ambiguous tone in annual reports. This study highlights the contribution of female directors to the quality and transparency of financial disclosures and supports recent regulatory initiatives aimed at enhancing female representation on corporate boards.

Eccrine Porocarcinoma: Clinical and Histopathological Study of 14 Patients with Special Emphasis on Sentinel Lymph Node Biopsy
Authors: Meriläinen Anna-Stiina , Von Willenbrand-Bäckmann Maria , Sihto Harri , Koljonen Virve
Published: July 2023

Eccrine porocarcinoma is a rare skin adnexal tumour that affects elderly people. Most eccrine porocarcinomas are stage I or II according to the American Joint Committee on Cancer. The prognosis is good in early stages, but worsens when advanced. Since information on the use of sentinel lymph node biopsy in these patients is scarce, this study examined the records of all patients with eccrine porocarcinoma treated at Helsinki University Hospital during a 17-year period and focused on sentinel lymph node biopsy patients. The study identified 14 patients (9 male, 5 female). There were 2 metastases to the lymph nodes and 2 recurrences at initial referral to our institution. All primary tumours had wide local excision and 6 patients also had sentinel lymph node biopsy, of whom none had positive lymph nodes. There were no new metastases or recurrences during follow-up. Three patients died of causes other than eccrine porocarcinoma. When comparing the wide local excision only and wide local excision with sentinel lymph node biopsy groups, no parameters reached statistical significance. The decision process of the multidisciplinary tumour board meeting on whether to perform sentinel lymph node biopsy was not clear, perhaps due to the limited knowledge of eccrine porocarcinoma. Further studies and international collaboration are warranted.
Er det plass til pårørende i arbeidslivet? HR og leder har betydning
Authors: Traavik Laura E. M. , Botnmark Kristin Molvik
Published: July 2023

In this chapter we investigate an often-neglected group in the workplace: people who are caregivers. A caregiver is someone who provides ongoing, informal, and unpaid support to at least one person, a family member or friend, to assist them during an illness or other debilitating life situation (Hunt, 2003). Our focus is on those who care for children with special needs or adults who require assistance. In an increasingly diverse workplace, and with demographic trends showing a growing number of older people in the Norwegian workforce, the likelihood that employees will have caregiving responsibilities (beyond child-rearing) at some time during their careers, is high. We survey 138 employed caregivers in Norway to explore the relationship between a caregiver’s experience of organizational support (both in terms of HR policies, practices, and leadership) and their experiences of inclusion, stress, and competence utilization. We found that HR policies executed as leadership practices are correlated with increased experiences of inclusion and competence use, and less stress. We discuss our findings and their implications for Norwegian organizations and their HR practices.
HR-analyse i norske virksomheter
Authors: Alsvik Lina , Slåtten Kåre
Published: July 2023

The concept of human resource analytics (HRA) involves collecting and analyzing HR data to improve decision making. HRA has in recent years surged greatly in popularity among practitioners and consultants, and the concept is currently the topic of conferences, magazine articles and blogs. To date, however, HRA has only to a limited extent been scrutinized from a more academic perspective. The article uses data collected from HR professionals to highlight the status quo of HRA and the main challenges encountered in the process of trying to make the concept work in a Norwegian context. We discuss how to overcome these challenges and identify the most important criteria for succeeding with HRA.
Ledelsesutdanningens muligheter: Om å utvikle en realistisk lederselvtillit i samspill med andre
Authors: Drake Irmelin
Published: July 2023

This chapter takes as its vantage point the fact that leadership is not something that can be taught or learned as a set of objective and universal skills and abilities. Thus, in dealing with an array of mixed and demanding leadership expectations, individuals may fall short of appropriate means to develop realistic leadership self-efficacy. Various dysfunctional misperceptions may be the result, including imposter syndrome, the Dunning-Kruger effect and/or succumbing to narcissistic personality types. What kinds of organizational support help individuals avoid or maneuver out of such dysfunctional thinking and behavioral patterns and instead make more realistic judgments regarding their own and others’ leadership capabilities? Research indicates that becoming aware of these phenomena is key. Changing one’s dysfunctional thinking patterns can be achieved via cognitive behavioral therapy. Other measures at the organizational and individual level are suggested and may be implemented by HR staff and current leaders. It is further argued that leadership education and self-leadership training may serve as an important measure to reduce, prevent and/or counter the development of imposter syndrome tendencies and help build leadership self-efficacy. Through various andragogical processes, it may be possible to reduce inclinations of overestimating other people’s leadership talent, underestimating one’s own, or simply gaining insight into others’ leadership experiences, learning processes and self-evaluations.
Leders handlingsrom i konflikthåndtering
Authors: Fjell Solfrid Mykland , Lange Birthe Kåfjord
Published: July 2023

Many managers experience dealing with conflicts as a challenging and demanding part of their job (Hansen et al., 2015). In this chapter we combine the judicial framework for handling work-related conflicts and sensemaking theory to discuss relevant demands, constraints and choices managers must balance when facing conflict situations. We find that the judicial framework contains many principles and regulations, yet less practical information or guidelines on conflict resolution, and while important, we find the formal judicial frameworks insufficient as a basis for understanding and developing managers’ maneuvering room in conflict situations. This chapter contributes to increased insights by combining legal frameworks with literature on sensemaking and managerial discretion. We include leaders’ interpretations and perceptions of conflict situations and possible actions available to address such situations. Furthermore, this chapter contributes to deepening leaders’ and HR-workers’ knowledge and hence broadening their repertoire of measures for applying managerial discretion when handling work-related conflicts. We provide a list of seven principles to guide leaders in work-related conflicts and point out practical implications.

BACKGROUND: A promising method for treating the pathology of the retinal pigment epithelium in age-related macular degeneration is cell replacement therapy.
AIM: The aim of the study was to analyze the results of cell transplantation in the form of a cell suspension into the subretinal space at various times.
MATERIALS AND METHODS: The material of the study was 20 rabbits (40 eyes) of the New Zealand albino breed. A month after the modeling of retinal pigment epithelium atrophy and retinal degeneration, rabbits underwent subretinal transplantation of induced retinal pigment epithelium in the form of a cell suspension. Optical coherence tomography and autofluorescence studies were conducted in a period of up to 8 months. Enucleated eyes of animals were subjected to morphological study.
RESULTS: When observing rabbits with a previously created model of atrophy in the long term, it was found that the cells of the transplanted retinal pigment epithelium remained viable for the entire period. There were no inflammatory reactions from the eyeball, clouding of the optical media, pathological changes in the structure of the retina.
CONCLUSION: Thus, with the introduction of a suspension of induced retinal pigment epithelium cells with atrophy of the retinal pigment epithelium, the injected cells retain their viability for up to 8 months.

Today, there are many manufacturers of triple-prism, spherical reflectors with different mechanical characteristics. That is why there is a problem of matching the signal reflection center with the geometric one. The purpose of this work is to evaluate the methods of determining permanent corrections of electronic tacheometers, ball reflectors and to develop recommendations for their use. Method. To determine the instrument correction, a displacement interferometer is used. It contains a two-frequency He-Ne laser with a wavelength of l = 0.63 μm (red range). The study compared the results of length measurements by an interferometer and an electronic total station with a ball reflector. This allowed determining the instrument correction. The research defined the constant correction of reflectors and total stations on the phase section of the field base using the method of created linear observations. Results. Experimental studies of ball reflectors of various manufacturers and Leica electronic tacheometers were conducted. The determination of constant instrument corrections of the total station and reflector using the displacement interferometer can be performed with an accuracy of 0.1 mm. This significantly depends on the accuracy of measuring lines with the total station. The use of ball reflectors with a built-in triple prism allows significant increase of distance measurement accuracy by reducing centering errors, considering the constant instrument correction (up to 0.4 mm for Leica 1201 total stations). Scientific novelty. The methods of determining permanent corrections of ball reflectors and total stations were investigated. The proposed method determines the measurement interval length with the exception of systematic constant correction of the electronic total station and reflector. Practical relevance. The use of ball reflectors is recommended for quick and unambiguous installation at points, convenience of their use for monitoring observations, as well as for increasing the accuracy of linear measurements due to the reduction of centering errors. In order to achieve high-precision measurements of short lines, it is recommended, according to the performed studies, to carefully determine the constant correction of the total station and ball prisms. This makes it possible to increase the accuracy of line measurements at least three times compared to the declared accuracy of the total station manufacturer.

Purpose. Statistical information for the period from 2016 to 2021 was used to analyze seismic activity. Objective. The aim of the study is to identify the relationship between changes in water level and local seismic activity in the region. Using HPP and Psing filtering, the hypocenters of earthquakes within a radius of 30 km from the seismic station with the NDNU index were selected, and using geographic information technology tools, the hypocenters of earthquakes were compared with the geological structure of the region. Methodology. Statistical information for the period from 2016 to 2021 was used to analyze seismic activity. Using filtering, the hypocenters of earthquakes within a radius of 30 km from the seismic station with the NDNU index were selected, and using geographic information technology tools, the hypocenters of earthquakes were compared with the geological structure of the region. Results. The studies revealed a correlation between seismic events and water level fluctuations in the reservoir. The paper also established the density of episodes concentrated in the reservoir operation area, as well as the magnitude and shallow depth, indicated the probability of activation of faults located in geological layers close to the ground surface. The stresses in the soils were assessed. Using the Coulomb-Mohr theory, the ultimate stresses leading to the destruction of structural ties were calculated approximately, and the optimal modes of operation of the reservoir were determined. Originality. The research in the article allows us to more accurately assess the effect of the stress gradient in the soils on the background seismicity in the reservoir operation area. Practical significance. The practical significance of this study is understanding the effect of the stress gradient on induction earthquakes. The described method, which is based on the principles of Coulomb's law and Mohr's theory, allows us to remotely study the behavior of the material under different loading conditions. This study and the development of a geomechanical model helps to better understand and predict earthquake behavior and determine safe loading zones. This has practical implications for the design and construction of structures, as well as for risk assessment and appropriate safety measures.

I. Subbotin Institute of Geophysics of the National Academy of Sciences of Ukraine. The movement dynamics of the base station was monitored by marks placed on the edges of the western and eastern sides of the laboratory building. To evaluate and compare the obtained results, satellite data were processed by the method of approximation of polynomial smoothing of the third degree. According to the results of periodic geometric leveling, it was established that for the period 2004-2019, the slow vertical movements of the stamps were 1.03-1.11 mm with an average annual rate of rise of 0.065-0.07 mm/year. Seasonal vertical movements of the permanent GNSS station POLV are within 2 mm/year, and in the first half of the year, there is a rise of the point and a decline was in the second half of the year. Selected components that can affect the vertical movements of a GNSS station installed on an engineering structure. A comparison of ground and satellite observations results was made for the periods of 2004-2005 and 2018-2019. Based on the observations and modeling, the component of vertical oscillations of the receiving antenna obtained in the period of 2004-2005 by both ground and satellite methods did not exceed 2 mm; in the period of 2018-2019, the analysis of satellite data showed an increase in fluctuations up to 7 mm. This can be explained by a large spread of satellite measurements. Scientific novelty and practical significance lie in the detected stability of the amplitude of vertical movements of the GNSS station, which was confirmed by the ground method of geometric leveling and the analysis of the time series of satellite observations. The conducted studies confirm the influence of various factors on the stability of receiving antennas.

In applied geodesy tasks, it may be necessary to determine spatial angles. When bringing a 3D design of buildings and structures to the field with the help of an electronic total station (ES), it is important to verify the spatial angles between different elements of building structures such as roof overlaps, inclined anchors, and more, using the characteristic points' spatial coordinates. Modern geodetic instruments provide sufficiently high measurement accuracy (up to 1" and 1 mm, respectively). However, measuring the required angles with surveying instruments is not always possible for various reasons. First of all, it is impossible to place the device at the vertex of an angle if the location is not accessible. This paper develops a method for determining a spatial angle whose vertex is not available for measurement. Methods and results. To achieve this goal, we consider one of the options for its determination through the application of the cosine theorem with preliminary measurement or calculation of adjacent sides and vertical angles. This article also presents an algorithm for solving the problem with an estimation of the accuracy of establishing the required parameters. The basic formulas for determining the angles of a spatial triangle with an estimate of their accuracy are proposed. The paper studies the influence of the linear measurement values of the lengths of the sides on the values of the angles of a spatial triangle with the corresponding accuracy assessment. In particular, the root mean square errors of angle calculation were determined based on these calculations and mathematical modeling, namely, the ratio of the sides of the triangle. Through indirect measurements of the tower crane boom and roof spire, the spatial angle values were determined. The inclination of the crane boom to the base resulted in α=910.712±51", while the angle of the roof spire was α=150.109±35". Scientific novelty and practical significance. On the basis of the proposed methodology and numerical experiments, spatial angles were determined and their a priori accuracy was analyzed. This confirms the influence of linear measurements of side lengths on the values of spatial angles. The obtained results make it possible to apply the proposed method in engineering and geodetic works using BIM technologies in 3D space. This method can be used in the application software of electronic total station manufacturers to determine spatial angles in space when solving engineering problems.
Optimal Control in Neurological Models of Information Warfare

Published: July 2023

Two neurological models of information warfare are considered. For each of them, the optimal control problem is considered, assuming that the Campaign Planner is associated with the governing body of one of the belligerent parties and distributes the volume of propaganda broadcasting in time.

The cost functional reflects the Planner’s desire to maximize the number of their supporters at a given time while minimizing costs during the campaign.

The problem is studied analytically, using the Pontryagin’s maximum principle.

Optimal control is obtained for various combinations of parameters.

The “increasing” type of campaign is aimed at ensuring that for most individuals information is received immediately before the finish line, and that the impression of this information does not have time to weaken. In contrast, the strategy of a “decreasing” campaign implies a high role of interpersonal communication: it is based on convincing a significant number of individuals of their position at the very beginning, who will then retell it to their interlocutors.

Published: July 2023

To effectively regulate traffic on highways and networks of modern megacities, it is necessary to introduce Intelligent Transport Systems, which include many innovative solutions, in particular, mathematical models for describing the dynamics of traffic flows.

The article is devoted to a brief description of the current state in this area in its development — from the simplest macroscopic and microscopic models that have become classic to modern developments.

Special attention is paid to the original multilane models developed by the authors of the article within both approaches.

The macroscopic model is based on the quasigasdynamic approach, while the microscopic one uses the ideology of cellular automata and constitutes a generalization of the Nagel-Schreckenberg model for the multilane case.

The difference in the representation method and the mathematical apparatus for the mac-roscopic and microscopic description of traffic flows is briefly described, followed by the review of the main models at different stages of their development, presented by foreign and Russian authors.

Special attention is paid to the three-phase theory of Boris Kerner and models built in the framework of this theory.

Examples of modern software for traffic modeling are given.

The original quasigasdynamic model of traffic flows, which uses the continuum approximation and is constructed by analogy with the well-known model of gas dynamics, is briefly described. Due to the introduction of the lateral speed, the model is generalized to the multilane case.

An original microscopic model based on the cellular automata theory and representing a generalization of Nagel- Schreckenberg model for the multilane case is described. The model has been further developed by taking into account various driving strategies and behavioral aspects.

The article presents a brief overview of the state of the art in the field of mathematical modeling of traffic flows, as well as original macroscopic and microscopic models developed by the authors for the case of multilane traffic.
