Purpose-A new design concept, playability, has emerged and been advocated as a decisive factor for players’ gameplay experiences. The present study intends to identify what playability factors might affect players’ gaming experiences, particularly from the perspective of individual motivation. Design/methodolgy/approach-According to the game heuristics and playability design guidelines, the pre...

A CCD or CMOS linear sensor it ́s an essential component in various applications of engineering and consume. In this work we will present the first stage of the design and development of an embedded system for monitoring the angular distribution of the intensity of a laser light. It is presented the purpose of developing this work and it is shown the first results of the system, which makes use ...

A new code sign implementation of vector median rational hybrid filter based on efficient hardware/software implementation is introduced and applied to colour image filtering problems. This filter is used essentially to remove impulsive and Gaussian noise in colour images. In our design we start by implementing the software solution in system on programmable chip context using NIOS-II softcore ...

After almost a decade of R&D, vehicular communications for cooperative systems and its enabling technologies, mostly relying on IEEE 802.11p and IEEE 1609.1-4 family of standards, are in their trial phase, as some major field operational tests are being carried out. Nevertheless, there are still some open problems concerning the timeliness, dependability and security of IEEE 802.11p based commu...

Digital watermarking is the technique of inserting specific information into signal, data, image or video. Copyright protection, data authentication, covert communication and content identification can be achieved by Digital watermarking. This work aims at developing a robust and secure blind watermarking technique for speech signal. The speech is watermarked using Virtex-5 FPGA which implement...

This paper presents a novel algorithm for field programmable gate array (FPGA) realization of vector quantizer (VQ) encoders using partial distance search (PDS). In most applications, the PDS is adopted as a software approach for attaining moderate codeword search acceleration. In this paper, a novel PDS algorithm well suited for hardware realization is proposed. The algorithm employs subspace ...

We study numerically the possibility for monitoring electron motion in a dissociating molecule using an attosecond XUV probe pulse which photoionizes a coherent superposition of two nuclear wave packets. We present the photoelectron spectra and forward–backward asymmetries in these spectra obtained from a numerical solution of the time-dependent Schrödinger equation for one electron and two pro...
