In this paper we address the problem of optimal co-design of control and quantization policies for a physically-interconnected system, where each subsystem has a local quantizer. The controllers are assumed to communicate with delay and cooperate in minimizing global quadratic cost. We show that for quantizers that act on the estimation error of the estimator conditioned on common information between controllers, separation holds. In other words, both quantizers can be optimally designed by minimizing a distortion function that is control-independent. Finally, for general class of quantizers we provide structural properties of the optimal control policy.

This paper studies the behaviour of observers for the slow states of a general singularly perturbed system – that is a singularly perturbed system which has boundary-layer solutions that do not necessarily converge to a slow manifold. The solutions of the boundary-layer system are allowed to exhibit persistent (e.g. oscillatory) steady-state behaviour which are averaged to obtain the dynamics of the approximate slow system. It is shown that if an observer has certain properties such as asymptotic stability of its error dynamics on average, then it is practically asymptotically stable for the original singularly perturbed system.

We study emulation-based stabilisation of nonlinear networked control systems communicating over multiple wireless channels subject to packet loss. Specifically, we establish sufficient conditions on the rate of transmission that guarantee ℒp stability-in-expectation of the overall closed-loop system. These conditions depend on the cumulative dropout probability of the network nodes for static protocols. We use the obtained stability results to study power control, where we show there are interesting trade-offs between the transmission rate, transmit power, and stability. Lastly, numerical examples are presented to illustrate our results.

Minimum attention control proposed by Brockett is an important formulation for resource-aware control, while his problem formulation and the underlying optimization problem that he proposed is in general very hard. In this paper, we propose a computationally tractable design method of minimum attention control based on promoting sparsity of the derivative of control. The optimal control problem is formulated as L0 norm minimization of the time derivative of control under the constraint that the derivative is bounded by a fixed value. This is a non-convex problem, and we propose L1 relaxation for linear systems to obtain optimal control by efficient numerical computation. We then show equivalence theorems between the L0 and L1 optimal controls. Also, we present an example of feedback control for the first-order integrator, that illustrates the proposed methodology.

We propose a unifying emulation-based design framework for the event-triggered control of nonlinear systems that is based on a hybrid small-gain perspective. We show that various existing event-triggered controllers fit the unifying perspective. Moreover, we demonstrate that the flexibility offered by our approach can be used for the development of novel event-triggered schemes and for a systematic modification and improvement of existing schemes. Finally, we illustrate via a simulation example that these novel and/or modified event-triggered controllers can lead to a reduction in the required number of transmissions, while still guaranteeing the same stability properties.

Pretpostavka je da dobiveni rezultati nakon analize mogu biti indikativni za osmišljavanje strategije unapređenja predmetnog opisa i prilagođavanja bibliotečkog kataloga savremenom korisniku; na osnovu korisničkih oznaka dodijeljenih jezikom korisničke zajednice.----------------------------------------------Researching of application of the user bookmarks in subject cataloguing: social bookmarkingThis research is done with the aim to find a solution on how to improve the accessibility of collections in catalogues and to improve subject cataloguing. The research is about questioning the application of user bookmarks of social marking within the subject cataloguing. The goal of this paper is to question the use of user tags in subject processing of the resources with comparative analysis of the bunch of keywords and user bookmarks of the articles in three journals including Vjesnik bibliotekara Hrvatske (2019); Glasnik Narodne biblioteke Srbije (2017; 2018) and Bosniaca (2019). This paper is highlighting the advantages of application user bookmarks in cataloguing and concluding that user bookmarks could improve and ameliorate access to a catalogue content through social bookmarking. The hypothesis is that the final result of analysis could be indicative of finding and designing a strategy that could improve subject cataloguing and adjustment of library catalogue to a modern user according to user tags which are assigned on common language.

U radu se osporavaju tvrdnje Dragiše D. Vasića u vezi sa stanjem historiografije u Sarajevu, te pokazuje koliko je Vasićev članak politikantski i bez naučnih kvaliteta. Na primjerima preimenovanja ulica u Sarajevu, „Bosanske doline piramida“, politike nastave historije u Sarajevu i festivala History Fest, autor pokazuje da Vasić ne donosi ništa novo, da ponavlja stare i poznate teze koje nemaju za cilj otvaranje naučnih diskusija nego sijanje mržnje. Autor tvrdi da se Vasić ne bavi ulogom historiografije u pojavama o kojima piše, nego prenosi stavove političkih elita, te je zbog toga Vasićev pristup historiografiji selektivan, nacionalistički obojen, sadrži politička etiketiranja i u skladu sa time posve je nenaučan.

The symposium held in Mostar in 1966, where the communists from Bosnia and Herzegovina publicly discussed the national issue of Croats, admitting also the wrong politics implemented after 1945 towards the Croats of West Herzegovina, aimed at the integration of West Herzegovina into the BiH framework, with the ultimate goal of integrating BiH for the purpose of achieving its equal status in the Yugoslav federation. After an extensive analysis of the situation in West Herzegovina that showed a mass emigration of Croats from the area to Western Europe, due to the negative political and economic situation, where they joined various immigrant groups mostly hostile towards Yugoslavia, the communist authorities had tried to end this trend and integrate the West Herzegovina area primarily around the regional center (Mostar), and then to open the perspective of a wider integration of Bosnia and Herzegovina around the centre of the republic (Sarajevo), for the purpose of imposing Bosnia and Herzegovina as an equal member of the Yugoslav federation. Although the attitudes presented at the 1966 symposium opened certain perspectives to Croats of West Herzegovina, some high-ranking politicians also showed resistance. Critics appeared who thought that opening of West Herzegovina, liberalization of the political attitude towards Croats and the removal of the ustaša legacy imposed to the area opened space for revitalization of the ustaša movement. The Belgrade press was at the forefront of such claims, using several terrorist activities that had taken place in that period in Yugoslavia (the movie theatre and the railway station attacks in Belgrade, planting explosives at the Zagreb Mirogoj Cemetery, etc.) as an argument, since the accused were Croats from West Herzegovina. BiH political leadership claimed that the attacks were orchestrated by political and intelligence circles who opposed the Mostar symposium, and that certain groups outside Bosnia and Herzegovina used those events as an opportunity to interfere into the political events in Bosnia and Herzegovina in order to compromise the politics of creation of national equality, which was the main political orientation of BiH communists.

In this work we adapt and evaluate different solutions for automatic speech recognition (ASR) to be used as an HMI for the assistant robot. Two on-device solutions: Kaldi (DNN-HMM) and Mozilla's DeepSpeech (end-to-end), and three internet service APIs: IBM Watson, Microsoft Azure and Google Speech to Text are evaluated. The systems are adapted to the domain of robot commands and evaluated on a set of expected inputs. As the goal is to retain the ability to recognise general language, the systems are also evaluated on out of domain data.

This article introduces a computational design framework for obtaining three‐dimensional (3D) periodic elastoplastic architected materials with enhanced performance, subject to uniaxial or shear strain. A nonlinear finite element model accounting for plastic deformation is developed, where a Lagrange multiplier approach is utilized to impose periodicity constraints. The analysis assumes that the material obeys a von Mises plasticity model with linear isotropic hardening. The finite element model is combined with a corresponding path‐dependent adjoint sensitivity formulation, which is derived analytically. The optimization problem is parametrized using the solid isotropic material penalization method. Designs are optimized for either end compliance or toughness for a given prescribed displacement. Such a framework results in producing materials with enhanced performance through much better utilization of an elastoplastic material. Several 3D examples are used to demonstrate the effectiveness of the mathematical framework.

Energy saving potentials related to steam generation and its usage in the medium size bakery are analyzed and presented. Input data needed for the investigation are gathered through detailed energy audit. Four energy savings measures are analysed in detail: 1) change of heat generator for space heating and domestic hot water preparation from steam boiler to condensing boiler, 2) reduction of heat losses from steam and condensate distribution lines, 3) heat utilization of return condensate and 4) replacement of the old, low efficiency steam boiler with high-efficient one. Implementation of these measures will result in substantial reduction of energy costs, ranging from 2.900 to 26.200 € annually. Interaction of all measures is analysed through energy efficiency improvement scenario, whose implementation will ensure significant energy cost savings, estimated at 40.793 € annually, with simple payback period shorter than 4 years. Implementation of presented measures will improve facility’s energy efficiency, represented through reduction of annual energy performance indicators by 6,14 %. Presented analysis revealed that steam generation and its usage in the industrial facilities offer a substantial potential for reduction of energy use and energy related cost.

The online platform is a platform of the future, both in the world and in Bosnia and Herzegovina. “The World Without a Label” is the first counseling center of this kind in BiH, because it brings together experts from behavioral, psychological, and psychiatric problems in one place. As a special problem of sociopolitical context is victims of sexual violence, war rape crimes. A case study shows a young boy is accompanied by a parent due to behavioral problems manifested by extremely bad social interaction with peers and for spending most of his free time on his computer playing video games. The boy’s mother had previously been treated in a psychiatric clinic’s day hospital, where she shared her own trauma of rape in group psychotherapy and the painful problems she faced in her early 20s, where Republika Srpska Army soldiers systematically raped captured Bosniaks. The father is a former member of the Bosnian army, and he himself had lot of war traumas. Experience in working in the Counseling Centers like this one, as well as with all the scientific and technological achievements, we have enabled the development of procedures for solving mental health problems through online platforms and standardization of those procedures.

Bosnia and Herzegovina has witnessed continuous depopulation since 1991. Depopulation was foreseen even without the emergence of war, but not nearly to that extent or that early. Bosnia and Herzegovina is in a worse demographic position than the European Union countries that show similar demographic trends. Very low birth rates, low fertility and low natural population growth have been recorded in the time of weaker economic development, which increasingly accelerates the emigration of the educated population in particular, and permanently adversely affects the reproductive potential of the country. This paper considers a hidden mutual relationship between the demographic situation (natural change, population ageing) in Bosnia and Herzegovina and its citizens' system of values. According to the survey conducted on 614 respondents, Bosnia and Herzegovina's citizens have fewer children than they would like.

In this paper, the authors analyse the legal nature of criminal procedure in Bosnia and Herzegovina, with the special emphasis on reform processes of criminal procedure legislation and adoption and acceptance of new legal solutions over the past two decades, acknowledging the aspiration for effectiveness and protection of basic human rights and freedoms. For the purpose of effective criminal procedure, it identifies the main and secondary actors in criminal proceedings whose role is crucial from the aspect of shedding light on and resolving a certain criminal matter, as well as issuing a judicial decision. To that end, the role and importance of those actors in taking procedural actions to carry out a criminal procedure task is emphasised for the purpose of understanding the legal nature, structure and course of the criminal procedure, and achieving the scope of legally prescribed rights of the suspect, that is, the defendant. In addition, special attention is paid to the specific procedural situation and status of an underage person in the criminal law as the perpetrator and injured parties in a criminal case, taking into account their age as the basis for the differentiation and protection in relation to adults.

Bosnia-Herzegovina and Republic of Croatia share 931km of border (494km land and 425km riverine), which has been contentious for the greater part of the modern European history and represented one of the hardest and most-militarized border demarcating the frontiers of the major empires. Nowadays, it is in the process of becoming another hard-border between the Schengen-Zone EU and non-EU Western Balkans. In this study we are considering several strategic elements required for planning of effective and constructive border security, while countering variety of pseudo-hybrid warfare operations as well as tactical considerations when responding to crisis, communications and overall control of the fluid frontier. Strategic elements taken into consideration are:  a) overall contiguity of the border, b) communications network / trafficability at border-crossing and c) geospatial support in the intelligence preparation of the area. Tactical elements considered are a) real-time geospatial support during operations b) alternative communications and vetting of alternative communications c) defensive operations (e.g. drone defense, jamming defense, incursion prevention). We are considering lessons-learned from the hostilities and frozen-conflicts in Yugoslavia, Ukraine, Afghanistan, Yemen and potential future conflagrations in Trans-Dnistria, Bosnia-Herzegovina, Kosovo* and the Baltics. We are using several criteria in understanding the required geospatial preparations required to undertake or defend against mass-migrations and potential hybrid threats such as unresolved territorial issues, population density information, infrastructure condition, land-use and overall completeness and availability of geospatial data. * Designation without prejudice to positions on status, and is in line with UNSCR 1244 and the ICJ Opinion on the Kosovo Declaration of Independence
