The growing awareness of environmental sustain-ability has led to new investments in the field of electric vehicles. One of the most expensive and important components of electric vehicles are their batteries, with battery management systems (BMS) being responsible for their control. New regulations, such as those of the European Union, aim to introduce battery passports as a way to track battery lifecycle from manufacturing, over second-life use, to recycling. Given the vast amount of data generated during the lifecycle of a battery, the current research is focused on combining BMS with cloud connectivity. However, not much research has yet been done in the area of BMS cloud security and secure data logging. To address this gap, we propose a novel solution for secure BMS data acquisition for on-premise and cloud environments. In this paper, we make two main contributions: a secure data structure for BMS logging and a secure architecture for transferring BMS data from its source to cloud and end systems. We demonstrate the feasibility of the design by developing a prototype with real components and evaluate it in terms of security and performance.

Abstract Migration’s impact spans various social dimensions, including demography, sustainability, politics, economy, and gender disparities. Yet, the decision-making process behind migrants choosing their destination remains elusive. Existing models primarily rely on population size and travel distance to explain the spatial patterns of migration flows, overlooking significant population heterogeneities. Paradoxically, migrants often travel long distances and to smaller destinations if their diaspora is present in those locations. To address this gap, we propose the diaspora model of migration, incorporating intensity (the number of people moving to a country), and assortativity (the destination within the country). Our model considers only the existing diaspora sizes in the destination country, influencing the probability of migrants selecting a specific residence. Despite its simplicity, our model accurately reproduces the observed stable flow and distribution of migration in Austria (postal code level) and US metropolitan areas, yielding precise estimates of migrant inflow at various geographic scales. Given the increase in international migrations, this study enlightens our understanding of migration flow heterogeneities, helping design more inclusive, integrated cities.

This paper will problematize a teaching methodological approach to the novel Skretnice, in which the students’ communication competencies are put in the foreground. This paper tries to show how interpretation still occupies a special position in the modern teaching methodology of teaching literature by connecting the modern teaching methodological models and students’ needs. In the process of the teaching methodological processing of the novel Skretnice by Jasmina Musabegović, we try to combine the elements of various methodical approaches: interpretation, a problematic, open teaching methodological approach. The goal is to elaborate a reading strategy and development of language skills/competencies: reading, speaking, listening and writing. The novel will be set as a literary template in the function of developing fundamental students’ competencies, in which a teaching methodological interpretation of the novel will be further developed. We will direct the students’ activities towards independent reading, research and writing about the topics and problems raised by the novel and its openness for cross-subject correlations.

This paper uses examples of essay interpretations by Enes Duraković, who are at the very top of Bosnian and Herzegovinian literary critical thought, to show how this literary and scientific genre can be actualized in literature teaching. Essay interpretations by Enes Duraković, especially one of the most significant Bosnian and Herzegovinian poets, can be a good incentive for pupils and students to develop basic communication skills, reading habits and abilities, as well as an example for practicing essay expression. The paper points to the well-known facts that the essay is a neglected literary and scientific genre in literature teaching. The essay is a hybrid genre, located between the subjective literary and artistic and scientific fields. It is precisely such a poetic character that enables the representation of essays in various methodological approaches, from analytical-interpretative to more complex methodological systems: problem-based, correlation-integration and open approach. Using the examples of Duraković’s essay-interpretative approach to the poetry of Muse Ćazim Ćatić, Skender Kulenović, Mako Dizdar, we will show how an essay can be a good motivation for reading literary texts, in reading lessons, and as an introduction to a lesson about a writer or literary historical period.

The purpose of this paper is to show how the elements of oral literature interpolate in the contemporary literature for children and youth of the prominent Bosnian-Herzegovinian authors Alija Isaković and Ljubica Ostojić.Firstly, this Paper theoretically elaborates on the presence of the elements of oral literature in the literature for children and youth. These two different literary directions touch each other at their roots, and in the contemporary interpolation, they exist parallelly in the genre re-semanticization of the elements of oral literature. Following theoretical postulates of the most prominent authors from the South-Slavic Interliterary Community in the field of researching oral literature and literature for children and youth, we will show how the linguistic-stylistic heritage is re-interpreted through the traditional oral literary forms in the texts of contemporary authors, and how the elements of orality appear in new narrative structures- short stories and fairy tales of a new type. We will show how the rhetorical and rhythmical values of a text spill over in linguistic audacity, and how old oral structures; folk songs, and folk tales are narratively defamiliarized, deconstructed, and parodied.

This Paper starts from the fact that the literature for children and youth is traditionally burdened by pedagogizing, dominance of adults’ desires, censorship and that there are still not enough topics which are important for children and youth, because many such topics remain taboo. Adults, who normally determine contents and norms in this literature, hypocritically remain silent about the topics that concern those who primarily should read this part of literature. The authors consciously avoid the topics that talk about death, various deviations such as family break-up, parents’ divorce, alcohol, drugs, children in exile, and other „hard“, traumatizing topics. However, the traditional canon changes over time, as we will show with the examples from Lijeve priče by Alija Isaković, the Bosnian-Herzegovinian „prose in jeans“ and Alen Mešković’s novel. Although the attitude towards taboo topics in the literature for children has changed to some extent, there are still not enough topics which are marginal and tackle taboo, but children and youth encounter them in their lives. The dominant view is still that it is better to tacitly bypass these topics, because each change is conditioned by the social situation. Changing attitudes towards taboo topics always implies an author’s willingness for opening new polemics in society. At the end, the Paper concludes that bad examples dominate in literature as well as in life. The oldest example of this is Aesop’s fables, which teach children and adults. Because of that, as well as the fact that the modern times in lives of children and youth change the attitude towards traditional taboo topics, authors and society are expected to more flexibly accept changes which imply a different attitude towards the real interests of children and youth.

Hardware channel emulators are essential for developing and testing transceiver prototypes in laboratory settings. They should be able to monitor the dynamic motion of the mobile terminal. This paper presents a narrowband Multiple-Input Multiple-Output (MIMO) channel emulator implemented on Field-Programmable Gate Array (FPGA). The proposed emulator is based on Non-Line-of-Sight (NLoS) non-isotropic scattering with arbitrary motion dynamics of the mobile terminal. Its standalone hardware architecture ensures the flexibility and scalability of further hardware realization. Our proposed emulator is validated by comparing the emulated statistics of the channel gain against simulated results under a circular antenna trajectory. The Probability Density Function (PDF) of the fading envelope is observed to perfectly match the theoretical Rayleigh distribution(stationary channel) and the auto-correlation function(non-isotropic scattering) also shows a close agreement. The successful alignment of the eigenvalue of the channel gain matrix indicates our proposed emulator can perform correct MIMO characteristics.

This paper considers an application of deep learning for channel estimation with imperfect frame synchronization in mobile communication systems. Without prior knowledge of the channel model and its characteristics, the proposed method can dynamically estimate and track channel transfer function variations based on received pilot symbols. Furthermore, this method is applicable in practical scenarios, as it considers imperfect frame synchronization and channel estimation for high-speed wireless communication scenarios. The performance and practical feasibility of the deep learning (DL)-based models are assessed by taking into account realistic frequency-selective fading scenarios. Numerical results demonstrate that the proposed method performs better for practical signal-to-noise ratios than the state-of-the-art approaches. In addition, the fine frame offsets are estimated and compensated in the synchronization block with a DL-based algorithm, which outperforms the traditional fine frame synchronization algorithms.

The deep energy method (DEM), a type of physics-informed neural network, is evolving as an alternative to finite element analysis. It employs the principle of minimum potential energy to predict an object’s behavior under various boundary conditions. However, the model’s accuracy is contingent upon choosing the appropriate architecture for the model, which can be challenging due to the high interactions between hyperparameters, large search space, difficulty in identifying objective functions, and non-convex relationships with the objective functions. To improve DEM’s accuracy, we first introduce random Fourier feature (RFF) mapping. RFF mapping helps during the model’s training by reducing bias toward high frequencies. The effects of six hyperparameters are then studied under static compression, tension, and bending loads in planar linear elasticity. Based on this study, a systematic automated hyperparameter optimization approach is proposed. Due to the high interaction between hyperparameters and the non-convex nature of the optimization problem, Bayesian optimization algorithms are used. The models trained using optimized hyperparameters and having Fourier feature mapping can accurately predict deflections compared to finite element analysis. Additionally, the deflections obtained for tension and compression load cases are more sensitive to variations in hyperparameters than bending.

Historical examples show and confirm the continued disenfranchisement of people with disabilities in all areas. In this regard, it is not a particularly different situation in the field of media representation of this marginalized group. A low level of awareness and knowledge about disability contributes to people with disabilities directly or indirectly discriminating, marginalizing, and at the same time creating unfounded attitudes, stereotypes, and stigma about them. Starting from the above, the text analyzes the current media presentation of persons with disabilities in Bosnia and Herzegovina. The analysis included printed, more precisely the content of daily editions of Dnevni avaz newspaper in the period from April 1 to May 4, 2023, in which, in the analyzed period, a total of nine (9) topics were published. The contents of electronic media (Federal Television, Radio Federation of Bosnia and Herzegovina, Radio-Television of Republika Srpska, Radio-Television of Republika Srpska, Radio Republika Srpska) were also analyzed, and on which, in the period from 08 to 22 May 2023, nine (9) topics that directly or indirectly concern people with disabilities were presented in news shows. The research aimed to point out the inadequate approach to reporting on disability more precisely to point out that people with disabilities and topics important to them are marginalized in media content in Bosnia and Herzegovina, and that they do not reflect the real-life conditions of members of that population.

The fundamental purpose of education is to make people aware and to encourage them to freely and responsibly improve themselves. The first step of (self) shaping a person goes through the family, which has a significant role in mediating general human values, especially those of the highest natural values - morals. This work aims to examine students' perspectives on the role of the family in the transmission/mediation of moral values. The research participants are students of the first and second cycle of the Department of Pedagogy at the Faculty of Philosophy of the University of Sarajevo (N=100). Analyzing their perspective and life experience, we obtained results that indicate a high degree of concordance between the framework of pedagogical understandings of morality and how moral values are transmission/mediated in their families of orientation. Also, the results show that frequent family conversations are the basis for building moral knowledge, beliefs, behavior, and actions in children and youth.

Future vehicular communication systems will extend deployed frequency bands from sub-6 GHz to millimeter wave (mmWave). To investigate different propagation effects between sub-6 GHz and mmWave bands in high-mobility scenarios, we proposed a suitable testbed setup to compare these two bands in a fair manner. Experiments conducted using the proposed testbed provide realistic results, but they are only usable if they can be faithfully reproduced. To quantify the reproducibility of the proposed testbed, we perform channel measurements at center frequencies of 2.55 GHz and 25.5 GHz at a velocity of 50 km/h. We investigate the influence of antenna pattern, time between measurements, signal-to-interference-and-noise ratio (SINR) and signal bandwidth on the reproducibility in terms of the channel correlation.

This work introduces a new perspective for physical media sharing in multiuser communication systems by proposing a novel scheme that enables the recovery of the content of the transmitted message whenever collisions happen. An alarm monitoring system is taken as a merely illustrative toy-model, but indeed the framework is generally applicable. In this scenario, the alarm system is designed to first decide whether a predetermined event has happened over a certain period; if such an event has been identified, the decision node also needs to correctly classify from which sensor the message comes. Simulations corroborate the effectiveness of the proposed method in terms of the event transmission efficiency, when compared with variations of conventional methods like TDMA and slotted ALOHA.

Colorectal cancer (CRC) is the third leading cause of mortality worldwide. The Food and Drug Administration recently designated pembrolizumab, an immune checkpoint inhibitor (ICI) against a programmed death-1 receptor, as a breakthrough drug for the treatment of patients with mCRC whose tumors have deficient mismatch-repair gene expression (as evidenced by microsatellite instability-high) and patients with solid tumors with a high tumor mutational burden with ≥10 mutations/megabase. We present a patient with metastatic CRC having renal and adrenal gland metastases. Comprehensive molecular profiling performed on a site of metastatic CRC in the kidney revealed multiple genomic alterations characteristic of CRC and rare chromosome 9p24.1 amplification, resulting in a co-amplification of the PDL1, PDL2, and JAK2 genes. Although this genomic alteration may predict the response to ICI, the lack of pembrolizumab prevented the patient from receiving targeted treatment and succumbing to the disease.
