Traditional hardware description languages are limited when describing highly configurable and reusable hardware components. The paper introduces methodology based on a Python language for design of hardware component generators on higher abstraction level. The scripting language is used to produce customizable cycle accurate hardware behavior and open-source tools provide automatic conversion to...
A task of time delay estimation for wideband signals in non-Gaussian environment is considered. An approach based on application of robust DFT for obtaining spectrum estimates of sensor signals for observation interval is proposed and shown to perform better than conventional approaches for noise modeled as symmetric α-stable process.
Common problem in signal processing is reconstruction of the missing signal samples. Missing samples can occur by intentionally omitting signal coefficients to reduce memory requirements, or to speed up the transmission process. Also, noisy signal coefficients can be considered as missing ones, since they have wrong values due to the noise. The reconstruction of these coefficients is demanding task,...
The paper suggests a generic model for compilation and definition of explicit parallelism in embedded computing systems (ECS), based on clustering. It also describes a rule-oriented production model of an expert system for analyzing implicit parallelism that employs a criteria-based fuzzy-set approach, the number of such criteria equal to the number of ECS modules, and also on the microprogram's memory...
The paper describes the development of prototype wheelchair platform controlled by the gestures. Leap Motion Controller is used to acquire data while changing the hand position. The novel user interface was developed, which shows the hand position to the user and combines the classical button GUI switchboard. The developed system is cloud based and integrates speech recognition to engage the motion...
Biomedical engineering employs engineering expertise in solving biological and medical problems to improve the quality of life. The paper describes the significance of combining life sciences with technology and engineering, and discusses objectives and characteristics of biomedical engineering education. Huge interest in this area and also a rapid development of relevant engineering fields provides...
This paper presents the ways to design low budget and high performance laboratory exercises for the purpose of biomedical engineering education. The methodology is based on "use what you have" principle, i.e. compose the BME exercise from the components available on a laboratory desk: inexpensive sensors/actuators, microcontrollers, acquisition interfaces, computers and widely used education...
The paper presents the designing process of the passive micromixer. Design parameters of microfluidic channel's geometry are optimized based on flow simulation results. CAD software Solid Works and application Flo Xpress are used for designing and simulation. Aim of presented student's work is not connected to any actual research activities. However part of MSc Thesis shows outcome of student's ability...
High physical, psychological and economic cost of sports injuries are the reason that lead to the recognition of a need for having a system to monitor health parameters of a professional athlete hence preventing incidences of severe injuries. Athletes in any sports can greatly benefit from feedback from the systems for improving the quality of their training. In this paper, we present architecture...
The article describes a approach of parallel data mining algorithms to be executed on multicore processors of various architecture. The suggested method presents an algorithm as a consequence of pure functions with unified interfaces. For parallel execution additional functions are introduced to share data and models between the parallel threads. Besides such functions allow to obtain various parallel...
An new invention or innovation (in the form of a device) is usually presented by technical drawing. The development of information technology in recent years has led to the fact that it is relatively easy present the invention by hologram also. This paper proves the assumption that the appearance of mechanical parts in the form of a hologram provides better visual perception than the technical drawings...
This paper deals with the study of dependence of subpixel accuracy of edge detection in 1-D images on number of used samples. Our study includes four methods for edge detection with sub-pixel accuracy in 1-D images: method based on approximation of real image function with erf function, moment-based edge operator, technique using spatial moments of the image function and the method based on wavelet...
An architecture for hardware realization of the Gradient algorithm for sparse signal reconstruction is proposed. Gradient algorithm is recently proposed and generally belongs to convex optimization class of algorithms. It is an iterative algorithm where missing samples are reconstructed by using a procedure of gradient-based concentration improvement. The proposed scheme assumes that sparse domain...
Handwritten digit strings and handwritten signature are used in various applications on a daily basis. Whether one signs a contract, work documents, petition, or wants to approve a cheque payment, one will use personal signature to do all those things. Similar is true for digits strings, where digit recognition is used in postal mail sorting, bank cheque processing, etc. In this paper we use this...
Statistical learning has recently seen an expansion of applications in different areas of science, finance and industry, as it plays a great role within the fields of statistics, data mining and artificial intelligence. Hence, it intersects with areas of engineering and other disciplines as well. It is used for both regression and classification problems. Solving these problems usually involves building/training...
In this paper, we have introduced a generalized block-lifting structure using the 2-D CORDIC algorithm as a block of 4-band linear phase paraunitary filter banks (LP PUFB) based on the quaternionic algebra (Q-PUFB) for the lossy-to-lossless image coding. A bank Q-PUFB based on the 2-D CORDIC block-lifting structure reduces the number of rounding operations and has a regular layout. Since the block-lifting...
Traditional methods rely on Static Timing Analysis techniques to compute the Worst Case Response Time for tasks in real-time systems. Multi-Core real-time systems are faced up with concurrent task executions, semaphore accesses, and task migrations where it may be difficult to obtain the worst case upper bound. A new three staged probabilistic estimation concept is presented. Worst Case Response Times...
