New Control Systems and Electronics Engineering Sections Published at Sciences Social Network

The Control Systems Engineering and Electronics Engineering Sciences are two new key engineering branches covered by the Sciences Social Network ScienceIndex.com. While the site currently contains a total of over 1,980,000 posts, the users of the website monitor 180 scientific journals publishing in these two new branches which feature almost 19,800 articles.

ScienceIndex.com is a Control Systems Engineering and Electronics Engineering Sciences Social Network established in 1998 to index the very latest news, headlines, references and resources from science journals, books and websites worldwide. The site covers news in all fields of biology, business, chemistry, engineering, geography, health, mathematics and society. In the field of Engineering Sciences, the site has now included the two new categories Control Systems Engineering and Electronics Engineering. While the Control Systems Engineering section covers systems in which outputs are forced to change in a desired manner during time, the Electronics Engineering section covers manipulation of voltages and electric currents by using devices.

ScienceIndex.com's Engineering Technology Category covers the design, manufacture, and operation of efficient and economical structures, machines, processes, and systems. Its eight sections include Architecture, Chemical Engineering, Civil Engineering, Communication, Control Systems, Electronics, Industrial Engineering, and Mechanical Engineering. Users can receive alerts for newly published content in this category by subscribing to ScienceIndex.com's Engineering Technology Category RSS feed.

ScienceIndex.com's Control Systems Engineering section covers systems in which outputs are forced to change in a desired manner during time. It currently contains 5,330 articles partly derived from 40 scientific Control Systems Engineering journals. The latest articles in this category are also available through a Control Systems Engineering Section RSS feed. One of the latest additions to this section presents a general stability criterion for switched linear systems having stable and unstable subsystems. The authors report conditions on a switching signal that guarantee that solutions of a switched linear system converge asymptotically to zero. These conditions apply to continuous, discrete-time and hybrid switched linear systems, those having both stable subsystems and mixtures of stable and unstable subsystems. Another recently included article presents a noise covariance estimation for Kalman filter tuning using Bayesian approach and Monte Carlo. The authors tested performance of the approach on various systems and noise properties and compare the speed of convergence with the Cramér–Rao bounds.

ScienceIndex.com's Electronics Engineering section covers manipulation of voltages and electric currents by using devices. It currently contains over 14,400 articles derived from 120 scientific Electronics Engineering journals. The latest articles in this section are also available through a Electronics Engineering Section RSS feed. One recently included article in this section covers electroreduction of NOxz species in alkaline medium on Pt nanoparticles. The authors' electrochemical analysis demonstrates that nitrite ions were reduced from −0.6 to −0.78V and the charge transfer step is attributed to the NO2−/NO redox couple. Another article presents a novel feeding topology for DC electric arc furnaces utilizing PWM-AC choppers. In contrast with traditional power supplies such as 12-pulse thyristor-based rectifier and 12-pulse diode rectifier–DC chopper-based power supplies, the proposed configuration stands out because of the reduced number of rectifier units and output reactors. The authors show through analysis and simulation that in comparison with traditional feeding systems, the proposed topology can lead to smaller input filter size, total unbalance and harmonic distortion reduction, and power factor improvement. The authors of another article propose a new method for non-contact measurement of the distribution of electrostatic charge on a surface based on scanning the sample surface with a focused high frequency acoustic beam to excite movement of the sample surface.

The Sciences Social Network currently contains over 1.98 million posts distributed among its' 68 categories. 83,400 users monitor nearly 14,200 journals publishing within the scope of the site. Since new science content is discovered in real-time, the delay between original publication and appearance at ScienceIndex.com is no more than two days. The site provides an advanced search feature which suggests up to ten closely related articles for a search and every displayed post.
