This paper suggests tools that provide significant improvements in the design and verification of FPGA-based digital circuits. These tools include reusable specifications of hardware components (modules) that have been proposed for two types of CAD environments; Xilinx ISE 5.x and Celoxica DK1. The components can be employed to implement both(More)
The paper describes novel multimedia tools and architectures for hardware/software co-simulation of reconfigurable systems. The main contributions are provided in the following three areas: 1) multimedia tools making it possible to manage animated graphical objects for virtual simulation of real world physical objects in the scope of reconfigurable system(More)
Electronic devices used in the scope of robotics and embedded systems have to be adapted to numerous external events and many of them might be unknown in advance. This application-specific particularity requires environment-specific adaptation and frequent changes in the pre-defined behaviour. In general, all feasible functionality cannot be incorporated in(More)
The paper discusses an FPGA-based prototyping system with both wired and wireless programming and data exchange facilities. The system can be efficiently used for different types of portable devices. For example, it can supply additional interfaces to mobile computers; can be seen as a hardware accelerator for solving computationally complex problems or(More)
H and Pt NMR are used to probe the spin 1⁄2 anion chain in the quasi-one-dimensional conductor Per2[Pt(mnt)2], which exhibits nearly simultaneous charge density wave (CDW) and spin-Peierls (SP) transitions at low temperatures (Tc ~ 8 K). Below Tc the [Pt(mnt)2] chain forms a spin-singlet state that is evident in H NMR spectra and spin relaxation (1/T1)(More)
We summarize structural instabilities exhibited by the one dimensional (1D) (arene)2X family of organic conductors in relation with their electronic and magnetic properties. With a charge transfer of one electron to each anion X these salts exhibit a quarter-filled (hole) conduction band located on the donor stacks. Compounds built with donors such as(More)
Currently, due to the progress made in the field of regenerative medicine, whole-organ bioengineering is becoming a valid alternative to cope with the shortages of organs for transplantation. In this chapter, we describe the main techniques carried out for pig liver bioengineering, which serves as an essential model for future human liver bioengineering.(More)
