Abstract Finger vein(s) based biometrics is another way to deal with individual's distinguishing proof and has recently received much consideration. The strategy in light of low-level components, like the dark surface of finger vein is taken as standard. However, it is typically looked with numerous difficulties that involves affectability to noise and low neighbourhood consistency. Generally finger vein recognition in view of abnormal state highlights the portrayal that has ended up being a promising method to successfully defeat the above restrictions and enhance the framework execution. This research work proposes finger vein-based recognition technique making use of Hybrid BM3D Filter along with grouped sparse representation for image denoising and feature selection (Local Binary Pattern – LBP, Scale Invariant Feature Transform – SIFT) to evaluate features, key-points and perform recognition. The experimental results on two open databases of finger vein, i.e., HKPU and SDU show that the proposed method has enhanced the overall performance of finger vein pattern recognition system compared with other existing methods.

Abstract Ultrasonography is an extensively used medical imaging technique for multiple reasons. It works on the basic theory of echoes from the tissues under consideration. However, the occurrence of signal dependent noise such as speckle destroys utility of ultrasound images. Speckle noise is subject to the composition of image tissue and parameters of image. It reduces the effectiveness of many image processing steps and decreases human perception of fine details form ultrasound images. In many medical image processing methods, despeckling is used as the preprocessing step before segmentation and feature extraction. Many speckle reduction filters are proposed but while combining many techniques some speckle diagnostic information should be preserved. Removal of speckle noise from ultrasound image by preserving edges and added features is a great challenging task in ultrasound image restoration. This paper aims at a comprehensive description and comparison of reduction of speckle noise of ultrasound fibroid image. Many filters are applied on ultrasound scanned images and the performance is marked in terms of some statistical measures. Even though several despeckling filters are there for speckle reduction, all are not good for ultrasound scanned images. A comparison of quality measures such as mean square error, peak signal-to-noise ratio, and signal-to-noise ratio is done in ultrasound images in despeckling.

Abstract This paper presents a strategic approach for implementing a Smart Pedestrian Network (SPN) navigation System that is geared towards promoting sustainable mobility. The SPN system is being designed to reach multiple market segments by providing information on suitable walking routes aiming to satisfy potential users’ needs, but also multiple stakeholder demands. The paper presents the main objectives of the SPN system as well as its system structure, application features, functions, and relevant data sources. The proposed strategic implementation framework deems necessary for scaling up so that the SPN system is successfully implemented in a variety of urban conditions. The framework emphasizes the element of adaptability, so that SPN can be adjusted where and when necessary, to deal with a variety of contexts and specific sustainable mobility issues, depending on the particular municipality conditions. The proposed framework combines elements of both the waterfall and agile software development methods, as well as, aspects of Open Innovation, Customer Involvement and Co-Creation taking a multiple stakeholder approach.

Abstract Despite the modern boom in technology, we are still faced with the fact that people write texts without diacritics. There are two main reasons for this. The first, historical reason stems from the past when the use of diacritics was troublesome and people would write text without them. The second one is the speed - typing without diacritics is usually faster. Text without diacritics is easy to understand for people, but for some types of documents, missing diacritics can cause a problem. This is also an issue when computers process such text. In this paper, we propose an algorithm based on word n-grams (a contiguous sequence of n words) that can restore diacritics of text written in the Slovak language. We also compare and evaluate our results with other algorithms developed for Slovak text.

Abstract Task scheduling and load balancing are a concern for service providers in the cloud computing environment. The problem of scheduling tasks and balancing loads in a cloud is categorized under an NP-hard problem. Thus, it needs an efficient load scheduling algorithm that not only allocates the tasks onto appropriate VMs but also maintains the trade-off amidst VMs. It should keep an equilibrium among VMs in a way that reduces the makespan while maximizing the utilization of resources and throughput. In response to it, the authors propose a load balancing algorithm inspired by the mimicking behavior of a flock of birds, which is called the Bird Swarm Optimization Load Balancing (BSO-LB) algorithm that considers tasks as birds and VMs as destination food patches. In the considered cloud simulation environment, tasks are assumed to be independent and non-preemptive. To evaluate the efficacy of the proposed algorithm under real workloads, the authors consider a dataset (GoCJ) logged by Goggle in 2018 for the execution of cloudlets. The proposed algorithm aims to enhance the overall system performance by reducing response time and keeping the whole system balanced. The authors have integrated the binary variant of the BSO algorithm with the load balancing method. The proposed technique is analyzed and compared with other existing load balancing algorithms such as MAX-MIN, RASA, Improved PSO, and other scheduling algorithms as FCFS, SJF, and RR. The experimental results show that the proposed method outperforms when being compared with the different algorithms mentioned above. It is noteworthy that the proposed approach illustrates an improvement in resource utilization and reduces the makespan of tasks.

Abstract Vehicular communication is the communication between the vehicles to provide intelligent transportation systems (ITSs) services to the end users. It is the most advance and emerging wireless technology in ad hoc network. On the other hand, construction of roads has a great impact in forwarding the data to the destination. As vehicles are moving with high speeds, the architecture of roads can change the performance of routing and data forwarding in the vehicular ad hoc network (VANET). If the construction of the roads in a city area is planned with intelligent junctions, flyovers, multilane, etc., then the performance of the system increases. In this paper, we have analyzed the impact of road elements like intersections, flyovers, multilane, buildings, hills, etc., on VANET routing and find solutions for the problems related to the performance of the system. We also simulate the impact of these elements in VANET routing and analyzed the performance using OMNeT++ network simulator and SUMO traffic simulator. The performance is studied by comparing standard GSR and GPSR position-based routing protocols.

Abstract The main goal of this contribution is to present the current developmental state of FRIMAN – the graphical development environment designed to support the teaching process of the object-oriented paradigm. FRIMAN project has two main purposes: 1. simplifying the understanding of the basics of the object-oriented programming for JAVA language beginners, 2. teaching students of applied informatics to collaborate in bigger project development. Therefore, an application called FRIMAN has been developed at the Faculty of Management Science and Informatics at the University of Žilina. This project is developed by students of Master degrees under the leaderships of experienced software developers. The suggested system consists of several modules. In this paper, we focus on the description of selected modules and their current functionality as well as description of future plans for this project and brief description of FRIMAN development process. Attention is paid to a module for class management and a graphical code editor, which enables the creation of method bodies using flow diagrams without the necessity of programming language syntax knowledge. Based on good evaluation by the development team preparing changes in the high school education process, the current application is planned to be applied in practice.

Abstract This article deals with a high order integration method based on the Taylor series. The paper shows many positive properties of this method on a set of technical initial value problems. These problems can be transformed into the autonomous systems of ordinary differential equations for both linear and nonlinear problems.

Abstract Recent advances in the field of web technologies, including the increasing support of virtual reality hardware, have allowed for shared virtual environments, reachable by just entering a URL in a browser. One contemporary solution that provides such a shared virtual reality is LIRKIS Global Collaborative Virtual Environments (LIRKIS G-CVE). It is a web-based software system, built on top of the A-Frame and Networked-Aframe frameworks. This paper describes LIRKIS G-CVE and introduces its two original components. The first one is the Smart-Client Interface, which turns smart devices, such as smartphones and tablets, into input devices. The advantage of this component over the standard way of user input is demonstrated by a series of experiments. The second component is the Enhanced Client Access layer, which provides access to positions and orientations of clients that share a virtual environment. The layer also stores a history of connected clients and provides limited control over the clients. The paper also outlines an ongoing experiment aimed at an evaluation of LIRKIS G-CVE in the area of virtual prototype testing.

Abstract Java is not only a modern, powerful, and frequently used programming language, but together with Java Virtual Machine it represents a novel dynamic approach of writing and executing computer programs. The fact that Java programs are executed in a controlled environment has several important implications that define the nature of the language and makes it different from the traditional C-like languages. Knowing the detailed differences between the two types of languages and execution environments is a part of the holistic education of a computer engineer. In this paper, we present some behind-the-scene details about the Java Virtual Machine and we show how these details could be used in the educational process to demonstrate the differences and to emphasise the advantages of the dynamic programming approach when compared to the static one. After presenting some information about class files and about the internal structure and operation of the Java Virtual Machine we demonstrate the usage of public domain programs that could be used in the educational process to put these theoretical concepts into practice.
