At 28nm technology and below, hot spot prediction and process window control on production wafers have become increasingly critical to prevent sensitive pattern geometries from becoming yield limiting defects as a result of process variation. We previously established a systematic approach to identify focus-sensitive hotspots, characterize their process window margins, use a focus variation map to...
Concern localization refers to the process of locating code units that match a particular textual description. It takes as input textual documents such as bug reports and feature requests and outputs a list of candidate code units that are relevant to the bug reports or feature requests. Many information retrieval (IR) based concern localization techniques have been proposed in the literature. These...
Modern Tokamaks have evolved from the initial axisymmetric circular plasma shape to an elongated axisymmetric plasma shape that improves the energy confinement, which is one of the key factors to improve fusion reactor performance. However, the elongated plasma cross section introduces a vertical instability that requires a real-time feedback control loop to stabilize the plasma vertical position...
Recently, many information retrieval (IR) based bug localization approaches have been proposed in the literature. These approaches use information retrieval techniques to process a textual bug report and a collection of source code files to find buggy files. They output a ranked list of files sorted by their likelihood to contain the bug. Recent approaches can achieve reasonable accuracy, however,...
This paper presents a new simulation strategy based on the hybridization of a full wave time domain multi-scale method, the Dual-Grid FDTD (DG-FDTD), and the Physical Optics (PO). This new method aims at simulating antennas mounted on large conducting platforms and whose nearby surrounding environment is very complex. Typical application fields of the hybrid DG-FDTD/PO method are the computation of...
This paper presents a rigorous analysis of a satellite antenna mounted onto its platform using the Dual-Grid FDTD method. In the first step of the method, the isolated antenna is analyzed. The study of the surrounded antenna is carried out in the second step of the DG-FDTD method. The results obtained in this realistic test case show the significant influence of the environment over the antenna.
The thermal ionization of the surface of thick metal, in response to a pulsed multi-megagauss magnetic field, is investigated experimentally and theoretically. Time-resolved imaging, pyrometry, spectroscopy, and laser shadowgraphy are used for characterization. Radiation-magnetohydrodynamic simulations are also used, which include the Eulerian MHRDR code and the Lagrangian RAVEN UP codes. An analytic...
In a mobile society, more and more devices need to continuously adapt to changing environments. Such mode switches can be smoothly done in software using a general purpose or digital signal processor though hardware components can cope with throughput and power constraints. In this paper we propose a methodology to implement multiple configuration (or mode) and multi-constraint systems into a single...
