| 1 | Integrated search technique for parameter determination of SVM for speech recognition显示文摘Support vector machine(SVM)has a good application prospect for speech recognition problems;still optimum parameter selection is a vital issue for it.To improve the learning ability of SVM,a method for searching the optimal parameters based on integration of predator prey optimization(PPO)and Hooke-Jeeves method has been proposed.In PPO technique,population consists of prey and predator particles.The prey particles search the optimum solution and predator always attacks the global best prey particle.The solution obtained by PPO is further improved by applying Hooke-Jeeves method.Proposed method is applied to recognize isolated words in a Hindi speech database and also to recognize words in a benchmark database TI-20 in clean and noisy environment.A recognition rate of 81.5%for Hindi database and 92.2%for TI-20 database has been achieved using proposed technique. | Teena Mittal R.K.Sharma | 2016 | Journal of Central South University2016，23，6： | 2 |
| 2 | FDTD based transition time dependent crosstalk analysis for coupled RLC interconnects显示文摘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. | Devendra Kumar Sharma Brajesh Kumar Kaushik R.K.Sharma | 2014 | Journal of Semiconductors2014，35，5： | 2 |
| 3 | 印度的食用菌产业及中印食用菌贸易前景显示文摘在印度,食用菌产业包括季节性栽培的食用菌厂和条件控制栽培工厂,被确定为农用工业。食用菌季节性栽培始于20世纪60年代,而现今出现了许多可控制环境的菇场。无论是季节性栽培还是可控制环境的菇场栽培,双孢蘑菇都是主栽品种。平菇和草菇在热带沿海地区多采用季节性栽培,但限于地区性消费。小型和中型的菇场内栽培的双孢蘑菇只进行鲜销,只有大型生产商才进行加工处理,远销到发达地区。食用菌通常是经过盐渍后用罐头和玻璃瓶包装后出口。早期,菌种和栽培技术是主要的制约因素,而现在市场则成为了最大的瓶颈。发展中国家的食用菌生产,与发达国家的高生产成本相比是有利可图的。邻国贸易往来是解决世界上远距离市场运输费用高的方案。对大多数生产者来说,种质的可用性逐渐成为各国普通栽培者面临的问题,菌种被盗用后,多被改成不同的名字。在多变的国际化条件下,中印双孢蘑菇和其他食用菌方面的贸易存在着巨大的发展空间。 | B.L.Dhar R.K.Sharma 高巍 | 2009 | 浙江食用菌2009，，2： | 1 |

| 5 | Chemically modified silica gel with 1-{4-[(2-hydroxy-benzylidene)amino]phenyl}ethanone:Synthesis, characterization and application as an efficient and reusable solid phase extractant for selective removal of Zn(Ⅱ) from mycorrhizal treated fly-ash samples显示文摘1-{4-[(2-hydroxy-benzylidene)amino]phenyl}ethanone functionalized silica gel was synthesized and used as a highly efficient,selective and reusable solid phase extractant for separation and preconcentration of trace amount of Zn(II) from environmental matrices.The adsorbent was characterized by fourier transform infrared spectroscopy(FT-IR),elemental analysis,13 C CPMAS NMR spectroscopy,scanning electron microscopy(SEM),thermogravimetric analysis(TGA) and BET surface area analysis.The dependence of zinc extraction on various analytical parameters such as pH,type and amount of eluent,sample flow rate and interfering ions were investigated in detail.The material exhibited superior adsorption efficiency for Zn(II) with high metal loading capacity of 1.0 mmol/g under optimum conditions.After adsorption,the recovery(> 98%) of metal ions was accomplished using 1.0 mol/L HNO 3 as an eluent.The sorbent was also regenerated by microwave treatment in milder acidic environment(0.1 mol/L HNO3).The lower detection limit and preconcentration factor of the present method were found out to be 0.04 μg/L and 312.5 respectively.The modified silica surface possessed excellent selectivity for the target analytes and the adsorption/desorption process remained effective for at least ten consecutive cycles.The optimized procedure was successfully implemented for the extraction of Zn(II) from mycorrhizal treated fly ash and pharmaceutical samples with reproducible results. | R.K.Sharma Aditi Puri Anil Kumar Alok Adholeya 2 | 2013 | Journal of Environmental Sciences2013，25，6： | 0 |
