A fast, robust and scalable methodology to examine, quantify, and 7 visualize climate patterns and their relationships is proposed. It is based on a 8 set of notions, algorithms and metrics used in the study of graphs, referred to as 9 complex network analysis. The goals of this approach are to explain known climate 10 phenomena in terms of an underlying network structure and to uncover regiona...

Modeling the unintended common- and differential-mode (CM DM) behavior of multi-converter power electronic-based systems can be a challenge. Chief among issues is need for detailed knowledge converter hardware to determine model parameters. In this paper, focus on derivation Thévenin-based models that only require characterization at terminals. Periodic linear time varying system analysis first...

the graphical technique for nonlinear circuits was described that enable us to optimize circuits to obtain maximum output power, maximum efficiency or minimum intermodulation. according to this method a high power amplifier in the ka band was designed. using a nonlinear model of the transistor, optimum slope for load-line was determined so that maximum power at the output was obtainable, then ...

In recent years, size of VLSI circuits is dramatically grown and layout generation of current circuits has become a dominant task in design flow. Standard cell placement is an effective stage of physical design and quality of placement affects directly on the performance, power consumption and signal immunity of design. Placement can be performed analytically or heuristically. Analytical placer...

In order to study the ability of coupled neural oscillators to synchronize in the presence of intrinsic as opposed to synaptic noise, we constructed hybrid circuits consisting of one biological and one computational model neuron with reciprocal synaptic inhibition using the dynamic clamp. Uncoupled, both neurons fired periodic trains of action potentials. Most coupled circuits exhibited qualita...

The physical motivation and rigorous proof of convergence for a particular network of nonlinear coupled oscillators are reviewed. Next, the network and convergence proof are generalized in several ways, to make the network more applicable to actual engineering problems. It is argued that such coupled oscillator circuits are more natural to implement in analog hardware than other types of dynami...

The frequency-dependent characteristics of microstrip planar circuits have been previously analyzed using several full-wave approaches. All those methods directly give characteristic of the circuits frequency by frequency. Computation time becomes important if these planar circuits have to be studied over a very large bandwidth. The transmission line matrix (TLM) method presented in this paper ...

Chiral quantum optics has attracted considerable interest in the field of information science. Exploiting spin-polarization properties emitters and engineering rational photonic nanostructures made it possible to transform from spin path encoding. Here, compact chiral circuits with deterministic circularly polarized routing beamsplitting are demonstrated using two laterally adjacent waveguides ...
