a general robotic mechanism was presented for in-pipe inspection oflevel pipes with varied diameter or curved pipelines. the robot employed three legs comprised of parallelogram linkages mechanism which enables adapting to various elbow joints in the piping systems. the curvatures in pipeline are the most important constraints in front of the robot through navigation process. to study the adapt...
It is widely-known that coupling exists between adjacent through-silicon vias (TSVs) in 3D ICs. Since this TSVto-TSV coupling is not negligible, it is highly likely that TSVto-TSV coupling affects crosstalk significantly. Although a few works have already analyzed coupling in 3D ICs, they used Sparameter-based methods under the assumption that all ports in their simulation structures are under ...
1. Introduction As the size of transistor keeps shrinking, advance of CMOS technology becomes more difficult and will eventually reach the physical limitation. To continuously reduce the form factor of the system with multiple chips, one straight forward solution is using stacked dies, called three-dimensional integrated circuits (3D IC). Recently, the technology of Through Silicon Vias (TSVs),...
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
this study was an attempt to explore the beliefs of iranian efl teachers about the role of grammar in english language teaching in both state schools and private language institutes. data were collected through a questionnaire developed by burgess and etherington (2002), which consisted of 11 main subscales and was divided into two sections. the first section dealt with approaches to grammar te...
In the present work, the transition matrix elements as well as differential and total scattering cross-sections for positronium formation in Positron-Hydrogen atom collision and hydrogen formation in Positronium-Hydrogen ion collision, through the charge transfer channel by Two-Centre Close-Coupling method up to a first order approximation have been calculated. The charge transfer collision is ...
In this paper, a novel and simple one-port de-embedding technique has been applied to through-silicon-via (TSV) characterization and modeling. This method utilized pad, via, and line structures to extract the equivalent circuit model of TSV. The main advantage of this deembedding method is that it can reduce the chip area to fabricate test element groups (TEGs) for measurements while keeping S-...
