Nadamo se da će ovaj kratak osvrt na zaostavštinu historičara Hamdije Kapidžića donijeti nove poglede na njegov život i znanstveni rad i poslužiti kao izvor za nova istraživanja.

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.

The prospect of a transnational feminist coalition is one of the most challenging questions that feminism faces today. The author analyzes Beauvoir’s involvement with the Algerian decolonization movement and her own self-critique as instructive tools for forming better ways for feminists to engage transnationally. Beauvoir’s existentialist ethics, political writings, and activism continue to offer models for developing an anticolonial and anti-imperialist transnational feminist ethics and are an underexplored resource in transnational feminist scholarship.

Carbonation of concrete is generally assumed to lead to reinforcing steel corrosion. This mindset has long dictated the research priorities surrounding the developments towards new, low-emission binders. Here, by reviewing documented practical experience and scientific literature, we show that this widely held view is too simplistic. In fact, there are many cases from engineering practice where carbonation of the cementitious matrix surrounding the steel did not lead to noticeable corrosion or to corrosion-related damage at the level of a structure. The influencing factors that can, however, lead to considerable corrosion damage are identified as the moisture state, the microstructure of the carbonated concrete, various species that may be present – even in minor amounts – in the concrete pore solution, and the cover depth. The circumstance that a reduced pH alone is not sufficient to lead to significant steel corrosion in concrete seriously challenges the established approach of assessing the  durability performance based on carbonation testing and modeling. At the same time, this circumstance offers great opportunities for reducing the environmental impact of concrete structures with low-emission binders. To realize these opportunities, the focus in research and engineering should shift from studying carbonation to studying corrosion of steel in carbonated concrete.

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.

Polazeći od potrebe iznalaženja rješenja poboljšanog pristupa građi u predmetnom katalogu; kao i poboljšanja predmetnog opisa; sprovedeno je istraživanje ispitivanja primjene korisničkih oznaka društvenog označavanja u okviru predmetne obrade građe. Cilj rada je komparativnom analizom korpusa ključnih riječi i korisničkih oznaka članaka triju časopisa Vjesnika bibliotekara Hrvatske (2019); Glasnika Narodne biblioteke Srbije (2017; 2018) i Bosniace (2019) ispitati primjenu korisničkih oznaka društvenog označavanja u predmetnoj obradi građe. U radu se naglašavaju prednosti primjene korisničkih oznaka u predmetnom opisu građe te se iznosi zaključak da korisničke oznake mogu unaprijediti i poboljšati pristup sadržaju u katalogu kroz korisničko označavanje; tj. društveno označavanje. 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.

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.

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.

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.

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.

Deep eutectic solvents (DESs), as an alternative to ionic liquids, have greener credentials than ionic liquids and have attracted increasing attention in many applications. Choline chloride-based DESs in combination with different hydrogen bond donors (organic acid, sugars and urea), showed a high extraction efficiency. The aim of this study was to examine the possible effects of choline chloride-based eutectic solvents on the antioxidant and antimicrobial activity of lemon and mandarin orange seed extracts. Lactic acid, glucose, urea and water were used to prepare choline chloride-based Natural Deep Eutectic Solvents (NADESs). Ferric-Reducing Antioxidant Power (FRAP) Assay and 2,2-diphenyl-1-picryl-hydrazyl (DPPH) method were used to determine Original Research Article Kolarević et al.; IRJPAC, 21(23): 120-128, 2020; Article no.IRJPAC.63470 121 antioxidant activity. Antibacterial activity was investigated by diffusion method on reference bacterial strains E. coli, E. faecalis, S. aureus, B. subtilis and L. monocytogenes. The analysis revealed a significant reduction potential of the eutectic solvent based on lactic acid as well as significant antioxidant activity of lemon and mandarin seed extracts. In general, mandarin extracts showed better antioxidant capacity. In vitro antibacterial activity assays showed a complete absence of bacterial growth inhibition of the extracts. However, eutectic solvents with lactic acid have shown a significant antimicrobial effect.

In adults 65 years or older, falls or other neuromotor dysfunctions are often framed as walking-related declines in motor skill; the frequent occurrence of such decline in walking-related motor skill motivates the need for an improved understanding of the motor skill of walking. Simple gait measurements, such as speed, do not provide adequate information about the quality of the body motion’s translation during walking. Gait measures from accelerometers can enrich measurements of walking and motor performance. This review article will categorize the aspects of the motor skill of walking and review how trunk-acceleration gait measures during walking can be mapped to motor skill aspects, satisfying a clinical need to understand how well accelerometer measures assess gait. We will clarify how to leverage more complicated acceleration measures to make accurate motor skill decline predictions, thus furthering fall research in older adults.

Online crowdsourcing sites/platforms have become popular in recent years. This study aims to uncover when, where, and how language learners in Turkey (TUR), Poland (POL), Macedonia (MAC), and Bosnia and Herzegovina (B&H) make use of the available crowdsourcing websites/games to learn foreign languages. To ensure parallelism among the data collected in the four countries, a cross-culturally appropriate online questionnaire in English comprised of two parts was designed for this study. Part one gathered information about the use of crowdsourcing sites, tools, and games, while part two elicited background information related to the participants (N=211). The data were analysed considering country- and context-specific variables. The results show that there are more similarities than differences in the ways informants in the studied countries perceive, and employ crowdsourcing resources to learn languages. Therefore, the findings might provide insights for experts, material developers and teacher trainers striving to create cross-culturally valid crowdsourcing platforms/games.
