Energy-efficient, thermal-aware modeling and simulation of data centers

Abstract: This paper describes the CoolEmAll project and its approach for modeling and simulating energy-efficient and thermal-aware data centers. The aim of the project was to address energy-thermal efficiency of data centers by combining the optimization of IT, cooling and workload management. This paper provides a complete data center model considering the workload profiles, the applications profiling, the power model and a cooling model. Different energy efficiency metrics are proposed and various resource management and scheduling policies are presented. The proposed strategies are validated through simulation at different levels of a data center.

Modeling and simulation of the pressing section of a paper machine

Abstract: We are concerned with modeling and simulation of the pressing section of a paper machine. We state a two-dimensional model of a press nip which takes into account elasticity and flow phenomena. Nonlinear filtration laws are incorporated into the flow model. We present a numerical solution algorithm and a numerical investigation of the model with special focus on inertia effects.

Modeling and simulation of piezoelectric mems energy harvesting device

Abstract: Piezoelectric MEMS power generator is used to harvest energy from the ambient vibrations in the environment. This paper proposes a structure design of MEMS power generator for low-frequency applications, which is based on bulk MEMS technology and (110) Si wafer. The structure consists of a silicon cantilever with a piezoelectric layer attached. The cantilever is modeled as an Euler-Bernoulli beam with a lumped mass beneath the tip of the cantilever, and then analytical modeling and simulations are carried out using MATLAB. Simulation results show that a tradeoff between the geometric parameters and the proof mass should be made for a high output power of the device. To increase the output power, the length of piezoelectric layer can be optimized, which is not necessarily equal to that of cantilever. Simulation results point out ways to perform the optimization of MEMS power generator. The analytical modeling and simulations are also helpful for the design of macro-scale power generator.

Measurement, modeling, and simulation of flip-chip CMOS ASIC simultaneous switching noise on a multilayer ceramic BGA

Abstract: This paper presents the simultaneous switching noise (SSN) measurements, modeling, and simulation of a flip-chip complementary metal-oxide-semiconductor (CMOS) application-specific integrated circuit (ASIC) test chip on a multilayer ceramic ball grid array (CBGA) package. Technology and design features of the chip and package test vehicles are described. Time-domain noise measurement techniques and results are presented in detail. Circuit modeling and simulation methodologies are developed and validated by strong correlation between measurement and simulation results.
