Deep Temporal-Recurrent-Replicated-Softmax for Topical Trends over Time

Dynamic topic modeling facilitates the identification of topical trends over time in temporal collections of unstructured documents. We introduce a novel unsupervised neural dynamic topic model named as Recurrent Neural Network-Replicated Softmax Model (RNNRSM), where the discovered topics at each time influence the topic discovery in the subsequent time steps. We account for the temporal ordering of documents by explicitly modeling a joint distribution of latent topical dependencies over time, using distributional estimators with temporal recurrent connections. Applying RNN-RSM to 19 years of articles on NLP research, we demonstrate that compared to state-of-the art topic models, RNNRSM shows better generalization, topic interpretation, evolution and trends. We also introduce a metric (named as SPAN) to quantify the capability of dynamic topic model to capture word evolution in topics over time.Comment: In Proceedings of the 16th Annual Conference of the North American Chapter of the Association for Computational Linguistics: Human Language Technologies (NAACL-HLT 2018

Primjena IC termografije za određivanje geometrije istrujnog mlaza u KGHV sustavima

A properly designed room air diffusion scheme ensures that when conditioned air is supplied into a room, it causes no discomfort to the occupants. To confirm the design characteristic of an air diffusion arrangement a measurement of different parameters of air movement pattern like jet geometry, air temperature and velocity or humidity must be done. IR thermography can be successfully applied for quick determination of the air jet geometry, not only for new and existing systems, but also in the design phase of air inlets and outlets. The paper presents the possibilities for the determination of jet geometry, radius and spread by means of IR thermography.Ispravno projektiran sustav za distribuciju zraka u prostoriji osigurava stanje ugode osobama koji u njoj borave. Da bi se potvrdili parametri koji karakteriziraju tu distribuciju, potrebno je izvršiti određena mjerenja poput geometrije mlaza, temperature, brzine i vlažnosti zraka koji se ubacuje u prostor. IC termografija se može uspješno primijeniti ne samo za brzo određivanje mlaza kod novih i postojećih sustava već i kod konstruiranja usisnih i odsisnih elemenata. Radom su prikazane mogućnosti određivanja geometrije mlaza kao što su domet i širina upotrebom IC termografije

Ninety Years of the Faculty of Mechanical Engineering and Naval Architecture of the University of Zagreb

U članku je ukratko prikazana povijest Fakulteta strojarstva i brodogradnje Sveučilišta u Zagrebu od osnutka Kraljevske visoke tehničke škole 1919. godine. Prikazana su razvojna razdoblja, današnja organizacijska struktura i nastavni program te osvrt na ulogu Fakulteta u osnutku i razvoju sličnih ustanova u Hrvatskoj.The article shows a short history of the Faculty of Mechanical Engineering and Naval Architecture of the University of Zagreb starting with the founding of the Royal High Technical School in 1919. The development phases are presented along with the present organizational structure and curriculum scheme. The role of the Faculty in the founding and development of similar institutions in Croatia is also described

CONSTITUTIONAL IMPLICATIONS OF EU MEMBERSHIP: AN OVERVIEW OF CONSTITUTIONAL ISSUES IN THE NEGOTIATING PROCESS – THE CROATIAN PERSPECTIVE

This article gives an overview of the constitutional issues arising from Croatia’s EU accession negotiations. Corresponding to the current status of negotiations, a provisional overview is made, consisting of the constitutional issues that are either already on the negotiating agenda or anticipated on the basis of the existing, internal legal analyses and/or the experiences of candidate countries from previous enlargements. They are divided into three groups: 1) constitutional issues which have arisen during the screening process and in subsequent talks and negotiations with the EU on individual negotiating chapters; 2) constitutional issues which have not been directly raised in negotiations with the EU, but which Croatia needs to consider in the context of the overall preparations for EU accession; 3) the possible further constitutional implications of EU membership following the entry into force of the latest EU treaty reform. The article looks at how Croatia and the EU approach these constitutional issues in the context of accession negotiations, especially having in mind the new procedural mechanisms (ie benchmarks) introduced by the EU into the process of negotiations. Different approaches are also determined by the type of constitutional issues: the sector-specific issues related to legislative alignment in certain areas of the acquis, which will be addressed in the course of negotiations on individual chapters, are distinguished in principle from the general constitutional issues related to finding the ‘right’ constitutional legal basis and formula for Croatia’s accession to and effective functioning in the EU (where Croatia has to decide on its own on the need for constitutional adjustments and the manner of making them). In comparison with the previous EU enlargement round, the analysis shows that there are no significant differences in Croatia\u27s accession negotiations with respect to the areas in which constitutional issues have been identified. Croatia will be able to use the experiences of the ‘new’ EU Member States, although there are no standard or best solutions for adjusting the constitutional legal framework for EU accession. The final list of all constitutional issues that Croatia will (have to) address before accession to the EU will directly depend on the results of negotiations as well as on wider legal and political deliberations that are expected to take place in Croatia in the coming period
