Modeling and analyzing electrical energy storage devices appears crucial for recently research in engineering study. This paper researches the power and impedance of fractional-order electric circuit models: super-capacitors and batteries. For super-capacitors and batteries models, the fractional order α plays an essential role in the power and energy obtained. An interesting phenomena found out is...
Using wireless sensor network to carry out status monitoring for floating bridge structure will improve the reliability and effectiveness of monitoring system greatly. To solve power supply problem of the network nodes, this paper designs a kind of self-sustaining piezoelectric power supply. It converts the mechanical energy which produced in the floating bridge's work environment into vibration excitation...
In thin-film transistor (TFT) logic circuit applications, propagation delay and power dissipation are two key constraints to be considered in optimal circuit design and synthesis. The unipolar zero-\(\textit {V}_\mathbf {GS}\) -load logic design is widely used for implementation of TFT digital circuits, because of the simple structure, easy processing, and relatively high gain. In this paper, the...
Energy efficiency of GPUs has facilitated the usage of GPUs in many complex scientific applications. Nodes with multi-GPUs along with multi-core CPUs are quite common in today's HPC landscape. This gives the flexibility to utilize CPUs or accelerators or even both according to the workload characteristics. It is not possible to measure power and energy accurately in all the cases, an alternate approach...
The EDA design flows must be retooled to cope with the rapid increase in the number of operational modes and process corners for a VLSI circuit, which in turn results in different and sometimes conflicting design goals and requirements. Single-objective solutions to various design optimization problems, ranging from sizing and fanout optimization to technology mapping and cell placement, must hence...
To effectively evaluate thermal behavior and inter-core communication on multi-core processors, we propose a simulation methodology and the corresponding implementation with runtime power and temperature calculation in this paper. The multi-core simulator is extended from our previous work, i.e. a heteromerous dual-core simulator. In our updated simulator, the well-established power model Wattch and...
