As FPGAs have grown ever larger, there has been a shift in the manner in which they are programmed. Early on, it was typical for designers to design all FPGA firmware in house using VHDL and Verilog. This gradually shifted towards design reuse at the IP Core Level. However in modern times, even designs at the IP level are having trouble adapting quickly enough to customer demands. This has resulted...
Project „Politehnika 2025” was started by Tehničko veleučilište u Zagrebu in cooperation with APIS IT, IN2 GRUPA and SPAN companies. The goal was to analyze future market needs until year 2025 and to upgrade existing and to develop new study programs that would modernize polytechnic studies. Project success depended on collecting and analyzing a large amount of data, and to do that it was required...
No-Reference (NR) Video Quality Assessment (VQA) is a challenging task since it predicts the visual quality of a video sequence without comparison to some original reference video. Several NR-VQA methods have been proposed. However, all of them were designed and tested on databases with artificially distorted videos. Therefore, it remained an open question how well these NR-VQA methods perform for...
This paper focuses on probabilistic analysis of hybrid energy systems (HES), which integrate multiple energy inputs and multiple energy outputs for effective management of variability in renewable energy and grid demand. To characterize the volatility, a statistical model combining Fourier series and autoregressive moving average (ARMA) is used to generate synthetic weather condition (e.g., wind speed)...
Symbolic execution is a systematic program analysis technique that has received a lot of attention in the research community. However, scaling symbolic execution continues to pose a major challenge. This paper introduces Synergise, a novel two-fold integration approach. One, it integrates distributed analysis and constraint re-use to enhance symbolic execution using feasible ranges, which allow sharing...
Order-preserving encryption and its generalization order-revealing encryption (OPE/ORE) allow sorting, performing range queries, and filtering data — all while only having access to ciphertexts. But OPE and ORE ciphertexts necessarily leak information about plaintexts, and what level of security they provide in practice has been unclear. In this work, we introduce new leakage-abuse attacks that recover...
At the outset authors of this article investigate the influence of ICT on archival practice. All archival processes are affected by latest developments in ICT. DMS and eSignature requirements and legislation (like MoReq and eIDAS) influenced record management practice. PAIS, OAIS and storage solutions have their impact on the archival management. Special audio and video format solutions influenced...
Nowadays, face recognition systems are going to widespread in many fields of application, from automatic user login for financial activities and access to restricted areas, to surveillance for improving security in airports and railway stations, to cite a few. In such scenarios, several architectures based on both 2D image analysis and 3D reconstruction are investigated and proposed in literature...
Motion-prediction algorithms for vehicles often employ historical behavior of a vehicle, rely on the Markov property of the underlying system, and predict the future behavior of the vehicle. However, the Markov property alone may lead to conservative predictions and heavy computational burden. To overcome these drawbacks, this paper develops a method that uses the notion of similarity among vehicle...
The aim of this study is to develop a time series classification method based on scale-space theory. Our study has been conducted in three steps: In the first step, scale-space extrema of time series found through using SiZer (SIgnificant ZERo crossings of the derivatives) method and local features set constructed around the determined extreme points, based on interval-widths list entered by the user...
Cloud computing is becoming a relatively mature paradigm in the ICT landscape. In light of the growing appetite for resources and service levels on par with user expectations, multi-cloud scenarios are becoming the next frontier in the usage of distributed datacenters for private and hybrid Cloud scenarios. Application deployment in particular is a noteworthy feature to be evaluated as microservices...
Our aim is to evaluate fundamental parameters from the analysis of the electromagnetic spectra of stars. We may use 103–105 spectra; each spectrum being a vector with 102–104 coordinates. We thus face the so-called “curse of dimensionality”. We look for a method to reduce the size of this data-space, keeping only the most relevant information. As a reference method, we use principal component analysis...
The Unified Modeling Language (UML) is widely taught in academia and has good acceptance in industry. However, there is not an ample dataset of UML diagrams publicly available. Our aim is to offer a dataset of UML files, together with meta-data of the software projects where the UML files belong to. Therefore, we have systematically mined over 12 million GitHub projects to find UML files in them....
Recently, sub-word based language models (LM) that use morphological and Part-of-Arabic word decomposition techniques are investigated for open vocabulary Arabic text recognition. Experimental results under different conditions (i.e; several Arabic databases) have shown that systems using subword LMs outperformed those using standard word LMs. This paper investigates and compares the efficiency of...
In the last decades, the web has experienced a quantitative explosion of digital data handled by companies or organizations, prompting web users to switch to NoSQL system dedicated to Big Data in order to support large web sites destined for a very big audience due to the scalability and high availability of this system. In the other hand, the semantic web technologies has emerged with their considerable...
In their mission of collecting, analyzing and disseminating statistic data, the National Institutes of Statistics are more and more confronted with personal data management. With the advent of the “Open Data” [1], the need for data diffusion and to establish a link between databases created during the surveys and censuses, are necessary for planning, monitoring and activities evaluation, in a context...
Conventionally, the modules of SCADA system such as Message broker, Human Machine Interface (HMI) Building Environment, Database Manager and drivers including the SCADA HMI are developed in compiler-based languages such as C/C++. Thus, the person who develops the SCADA HMI has to be well versed with that language whose learning curve is steep. Every time the user has to rely on the SCADA engineer...
This paper presents a study for generate digital business reporting using the language XBRL (Extensible Business Reporting Language) and its applicability in Ecuador. XBRL is a common language for the exchange of financial information, a specialized version based on XML. This standard has been implemented in Europe, USA, Canada, Oceania, Asia and some countries in Latin America, Ecuador have not adopted...
Drainage pumping station is an indispensable part of the drainage works, and the water hub for the urban drainage system's normal operation. The water cycle and transportation in urban drainage system are completed by a series of different functions of the drainage pumping stations, which burden the task of pumping the domestic sewage, industrial waste water and rainwater to the downstream pipe, water...
The development of a normalized morpho-syntactic Arabic lexicon is not an easy task. In fact, many norms allow the structuration and representation of lexical data. The adoption of a stable standard will guarantee the interoperability and interchangeability of lexical resources. Still, research work that deals with normalization for Arabic lexical resources is not well developed yet, especially for...
