FDTD based transition time dependent crosstalk analysis for coupled RLC interconnects

引用

Journal of Semiconductors 2014年第5期35卷 69-73页

The performance of high density chips operating in the GHz range is mostly affected by on-chip interconnects. The interconnect delay depends on many factors, a few of them are inputs toggling patterns, line ＆ coupling parasitics, input rise/fall time and source/load characteristics. The transition time of the input is of prime importance in high speed circuits. This paper addresses the FDTD based analysis of transition time effects on functional and dynamic crosstalk. The analysis is carried out for equal and unequal transition times of coupled inputs. The analysis of the effects of unequal rise time is equally important because practically, it is quite common to have mismatching in the rise time of the signals transmitting through different length wires. To demonstrate the effects, two distributed RLC lines coupled inductively and capacitively are taken into consideration. The FDTD technique is used because it gives accurate results and carries time domain analysis of coupled lines. The number of lumps in SPICE simulations is considered the same as those of spatial segments. To validate the FDTD computed results, SPICE simulations are run and results are compared. A good agreement of the computed results has been observed with respect to SPICE simulated results. An average error of less than 3.2% is observed in the computation of the performance parameters using the proposed method.

On Cosmic Ray and Geomagnetic Response to Coronal Mass Ejections （CMEs）

引用

Journal of Physical Science and Application 2011年第3期1卷 170-174页

作者： Nagandra k.mar sharma devendra Singh Faculty of Technology Chandra Shekher Azad University of Agriculture and Technology Campus-Etawah-206001 （U.P） India

A catalogue of type II bursts and the associated coronal mass ejections （CMEs） observed by the solar and heliospheric observatory （SOHO） mission is used to select the twenty three CMEs events with CME speed equal to and less than 450 km/sec （i.e., less than and equal to the average solar wind speed） during 1997-2008. Our observational results clearly indicate that even slow speed CMEs are capable to produce the cosmic ray and geomagnetic disturbances on day to day basis. The depression in cosmic ray intensity is larger three days after the arrival of the CMEs along with the maximum disturbance in geomagnetic activity on the same day （i.e., after three days from the arrival of CMEs）. Fluctuations in cosmic ray intensity and the geomagnetic activity are also observed before the arrival of the CMEs.

Minimally invasive osteosynthesis of distal tibial fractures using anterolateral locking plate： Evaluation of results and complications

引用

Chinese Journal of Traumatology 2016年第1期19卷 39-44页

作者： devendra Lakhotia Gaurav sharma kavin khatri G.N. kiran k.mar Vijay sharma kamran Farooque Department of Orthopaedics AIIMS New Delhi 110029 India

Purpose： Soft tissue healing is of paramount importance in distal tibial fractures fora successful outcome. There is an increasing trend of using anterolateral plate due to an adequate soft tissue cover on ante- rolateral distal tibia. The aim of this study was to evaluate the results and complications of minimally invasive anterolateral locking plate in distal tibial fractures. Methods： This is a retrospective study of 42 patients with distal tibial fractures treated with minimally invasive anterolateral tibial plating. This study evaluates the hone and soft tissue healing along with emphasis on complications related to bone and soft tissue healing. Results： Full weight bearing was allowed in mean time period of 4.95 months （3-12 months）. A major local complication of a wound which required revision surgery was seen in one case. Minor complica- tions were identified in 9 cases which comprised 4 cases of marginal necrosis of the surgical wound, 1 case of superficial infection, I case of sensory disturbance over the anterolateral foot, 1 case of muscle hernia and 2 cases of delayed union. Mean distance between the posterolateral and anterolateral incision was 5.7 cm （4.5-8 cm）. Conclusion： The minimally invasive distal tibial fixation with anterolateral plating is a safe method of stabilization. Distance between anterolateral and posterolateral incision can be placed less than 7 cm apart deoending on fracture oattern with proper surgical timing and technique.

American Journal of Plant Sciences 2012年第1期3卷 60-63页

作者： Sakshi Issar Saroj sharma devendra k.mar Choudhary Hemant k.mar Gautam R. k. Gaur 不详

Plant growth promontory Pseudomonas strains were isolated from root nodules of five plant species, viz., Trifolium pretense, Cicer arietinum, Amaranthus polygamus, Vigna mungo, and Trigonella foenum;that plants were denizen of Shekhawati region of Rajasthan. A total of 8 bacterial isolates were evaluated for growth promotion using PGP properties. Partial 16S rDNA sequencing data showed that these 8 bacterial isolates belonged to genus Pseudomonas. MEGA 4.0.2, software was used to construct a neighbor joining tree by employing boot strap method. Result exhibited significant diversity among recovered Pseudomonas strains.
