The increasing computation requirements of modern computer applications have stimulated a large interest in developing extremely high-performance floating-point dividers. A variety of division algorithms are available, with SRT being utilized in many computer systems. A careful analysis of SRT divider topologies has demonstrated that a relatively simple divider designed in an aggressive circuit...

This study investigated whether it was more beneficial to provide the learners in computer-based learning environments access to on-demand (self-regulated) help after they committed an error in problem solving or for the learning environment to externally regulate the presentation of instructional help. Furthermore, two different presentational formats—textual and pictorial—of instructional pro...

Reading is a hobby to open the knowledge windows. Besides, it can provide the inspiration and spirit to face this life. By this way, concomitant with the technology development, many companies serve the e-book or book in soft file. The system of this book of course will be much easier. No worry to forget bringing the digital circuit design for computer science students an introductory textbook ...

The law surrounding the patentability of computer-implemented inventions is extraordinarily unclear. Thankfully, the Federal Circuit has granted rehearing en banc to CLS Bank v. Alice to determine the test for computer-implemented inventions under § 101. This Note identifies three current approaches in Federal Circuit doctrine, and finds each lacking. In their place, this Note proposes and defe...

In this study, a simple design method of chaotic circuits is proposed, which utilizes an autonomous oscillator, a resonator and two diodes. By applying three kinds of oscillators and two types of resonators, six circuit models are obtained. It is con rmed that chaotic phenomena are observed in all of six models by both circuit experiments and computer calculations.

This paper presents a voltage based CMOS winner-take-all (WTA) circuit for analog voltage signals. The WTA circuit is based on a winner follower and wide-range transconductance amplifiers. The voltage based design uses capacitive storage for low power consumption. The circuit is modularized and its layout size is a linear function of the number of inputs. This makes the circuit easy to be imple...

Mathias Soeken, D. Michael Miller, and Rolf Drechsler Institute of Computer Science, University of Bremen, Germany Department of Computer Science, University of Victoria, BC, Canada The Pauli matrices are a set of three 2×2 complex Hermitian, unitary matrices. In this article, we investigate the relationships between certain roots of the Pauli matrices and how gates implementing those roots are...

We explore the chaotic behavior of a nonlinear electrical circuit constructed with simple components such as diodes and linear operational amplifiers. The circuit may be regarded as a nonlinear analog computer that gives a nearly exact solution of a particular chaotic model. Detailed comparisons between theoretical and experimental bifurcation points and power spectra yield differences of less ...

CAD plays a fundamental role in both top-down and bottom-up system fabrication. This paper presents a bottom-up circuit patterning process based on DNA selfassembly in terms of the design tool requirements and the new opportunities self-assembly creates for circuit designers. The paper also connects recent demonstrations of addressable selfassembly to applications in computer architecture and s...

The high performance personal computers (PCs) made possible an impressive development in the domain of the electric machines mathematical models. The circuit-field models become more sophisticated and are used more frequently in computing the electric machines characteristics. In the paper a personal point of view concerning the state of the art and the trends in this domain is presented.
