For a finite, well-mixed population of heterogeneous agents playing evolutionary games choosing to cooperate or defect in each round of the game, we investigate, when agents update their strategies in each round using the myopic best-response rule, how the number of cooperating agents changes over time and demonstrate how to control that number by changing the agents' payoff matrices. The agents are...
Modern manufacturing processes have allowed construction of 3D integrated circuits (IC) with embedded cooling. This technology has been proven to be the most effective solution for dissipating the high heat fluxes of up to 100 W/cm2 generated during the operation of 3D IC chips. Recent published works indicate that it is possible to maintain the maximum surface temperature below the allowable limits...
In multi-tier cellular/small cell networks, user performance is largely affected by the varying transmit powers, distances, and non- uniform traffic loads of different BSs in both the downlink (DL) and uplink (UL) directions of transmission. To optimize user performance in such networks, decoupled UL-DL association (DUDe) has recently been investigated. DUDe enables a user to be associated with different...
Voronoi diagram is a very important and practical geometric construction in computation geometry. In this paper, r- limited Voronoi diagram was introduced into the spatial pattern of corporate staff' safety awareness in emergent situation to describe the dynamic changes in the scope of swarm safety perception. Then, the virtual individual potential function of safety awareness emergency was put forward...
In this paper, a 60 GHz CMOS on-chip dipole antenna with helium-3 ion irradiated silicon substrate is designed using knowledge of electromagnetic simulation modeling. Rectangular region with 500 um × 1000 um around the dipole is irradiated by helium-3 ion and conductivity is reduced to 0.01 S/m (1 k Ohm cm). The width of dipole section is wide for broad bandwidth and reduction of conductor loss. There...
Four-level hybrid-clamped (4L-HC) converter is a newly proposed topology which is suitable for high-performance medium-voltage drives. Zero-sequence voltage (ZSV) is commonly used to balance the DC-link capacitor voltages of this topology and then the common-mode voltage (CMV) is also affected. This paper proposes a CMV reduction method for a back-to-back 4L-HC converter. The relationship of CMV and...
There are three important parameters in solar photovoltaic (PV) panel performance, namely maximum output power, short-circuit current, and open-circuit voltage. All these parameters are affected by temperature fluctuations. This research is focused on the behaviour of a mono-crystalline solar PV panel under different temperatures using experimental work and the results are validated with a corresponding...
Bayesian Networks have various applications including medical and technical diagnosis, financial scoring, and target behavior/pattern recognition. Bayesian Classification Networks fuse evidence from heterogeneous and homogeneous sources and calculate classification results. For many reasons, pieces of evidence from different sources can carry apparently contradicting information and in these cases...
A framework for the simulation of nanosecond laser annealing of structures found in 3D sequential integration is presented. The framework includes a finite difference frequency domain Maxwell solver and a Poisson solver for the thermal diffusion. Simple applications illustrate the advantages, expected difficulties and optimization levers of this annealing technique.
In this work, the Radiation Hardened by Design (RHBD) of an inverter cell is proposed. The design considers the use of standard CMOS processes with commercial PDK, focusing on fully incorporating the design into CAD tools allowing the automatic place & route. Corners and Monte Carlo simulations were performed in order to analyze and compare the performances between the standard cells and proposed...
This paper presents the analytical potential modeling of Double Gate (DG) Tunnel Field Effect Transistor (TFET) at 50 nm channel length. In this model approach the channel potential is sum of a long channel potential and a short channel perturbation along with the whole structure rather than just the Si/SiO2 interface or the channel centre. For the validation of our analytical modeling approach we...
This paper proposes a control strategy for grid interactive Power Conditioning System (PCS) which has a feedforward voltage control based on grid frequency detection. The PCS should supply the power to the critical load, regardless of the grid condition. In order to provide the power to the critical load continuously, the PCS should operate two modes. One is Grid-Connected mode and the other is Stand-Alone...
The steadily increasing complexity of integrated circuits raises the burden on verification engineers of sophisticated System on Chips (SoCs). Simulations and formal verification alone are not able to detect all problems in a design due to unforeseen interactions between modules. These problems may occur even if the modules are logically independent from each other due to physical effects. Bugs found...
In the paper some results of investigation of the single-phase transformer based AC pulse modulation mode regulated system of network voltage stabilization are presented. Switching processes in the device are regarded to application of transistor switches with proper snubbering circuits. Computer simulation as well experimental investigation of a model are done and its outcomes are presented.
The charge collection probability is one of the most important parameters of a solar cell. We derived two kinds of special functions to fit the external quantum efficiency and use then to reconstruct the charge collection probability. The simulation results of gallium arsenide and silicon solar cells are put into comparison.
In this paper, we present high voltage NLDMOS structure with multiple RSEURF concepts. The NLDMOS is based on 0.35µm BCD process. The multiple RESURF device base on charge balance theory using P-top and N-top to achieve high breakdown voltage and low on-resistance. The 2D simulation result compares the conventional single RESURF NLDMOS structure and the new structure with multiple RESURF devices....
This paper presents a new control scheme for virtual synchronous generators connected to weak grids. The proposed approach consists of two major parts. The first part holds a cooperative linear and nonlinear controller in order to emulate the synchronous generator behavior such that by preparing virtual inertia, power and frequency oscillations get damped. The second part deals with a control scheme...
We report a two-dimensional simulation study of a dopingless TFET with a hetero-gate dielectric. The energy band gap on the source side is modulated using a hetero-gate-dielectric in a dopingless TFET to increase the source-side tunneling rate. The use of a hetero-gate-dielectric, only on the source side, will ensure that the ambipolar current is not enhanced due to the drain-side tunneling. We demonstrate...
As signal speeds continue to increase, maintaining signal quality has become a greater challenge for signal integrity (SI) engineers. Migrating a system to a next-generation interface technology operating at higher speeds brings with it increased sensitivity to attenuation and jitter that can severely curtail reach and reliability. In order to meet the interface specification, expensive choices such...
With the rapid development of simulation science, knowledge reuse in this domain becomes a challenge. This paper concentrates on the system design of a simulation knowledge base management system. Furthermore, a semantic matching algorithm based on ontology has also been proposed for simulation knowledge retrieval.
