Speech recognition - A computer mediated approach
The computer revolution is now well advanced, but although we see a starting preparation of computer machines in many forms of work people do, the domain of computers is still significantly small because of the specialized training needed to use them and the lack of intelligence in computer systems. In the history of computer science five generations have passed by, each adding a new innovative technology that brought computers nearer and nearer to the people. Now it is sixth generation, whose prime objective is to make computers more intelligent i.e., to make computer systems that can think as humans. The fifth generation was aimed at using conventional symbolic Artificial Intelligence techniques to achieve machine intelligence. But it failed. Statistical modeling and Neural Networks falls in really sixth generation. The goal of work in Artificial Intelligence is to build the machines that perform tasks normally requiring human intelligence. Its true, but speech recognition, seeing and walking doesn’t require “intelligence”, but human perceptual ability and motor control.

Preconcentration and determination of trace amounts of Co(II) using Organic-solution-processable functionalized-Multiwalled carbon nanotubes by solid phase extraction-flame atomic absorption spectrometry
A novel and selective method for the fast determination of trace amounts of Co(II)ions in water samples has been developed. The first organic-solution-processable functionalized-Multiwalled carbon nanotubes (MWNTs) (SPFMWNTs) hybrid material with porphyrins. porphyrin–Multiwalled carbon nanotubes (MWNTs) nanohybrid, 5-4 (aminophenyl)-10, 15, 20-triphenyl porphyrin and its photophysical properties including optical (TPP) and grapheme oxide molecules covalently bonded together via an amide bond (TPP-NHCO- SPFMWNTs )were used as absorbent for extraction of Co(II) ions by solid phase extraction method. The complexes were eluted with HNO3 (2M)10% V.V-1 mthanol in acetone and determined the analyte by flame atomic absorption spectrometry. The procedure is based on the selective formation of Co(II) at optimum pH by elution with organic eluents and determination by flame atomic absorption spectrometry.The method is based on complex formation on the surface of the ENVI-18 DISKTM disks modified porphyrin–Multiwalled carbon nanotubes (MWNTs) nanohybrid, 5-4 (aminophenyl)-10, 15, 20-triphenyl porphyrin (TPP) and grapheme oxide molecules covalently bonded together via an amide bond (TPP-NHCO- SPFMWNTs ) followed by stripping of the retained species by minimum amounts of appropriate organic solvents. The elution is efficient and quantitative. The effect of potential interfering ions, pH, TPP-NHCO- SPFMWNTs, amount, stripping solvent, and sample flow rate were also investigated. Under the optimal experimental conditions, the break-through volume was found to about 1000mL providing a preconcentration factor of 600. The maximum capacity of the disks was found to be 568± 3 µg for Co2+. The limit of detection of the proposed method is 5ng per 1000mL.The method was applied to the extraction and recovery of Co in different water samples.

Molecular structure and spectroscopic analysis of 2, 6 dichlorophenyl isocyanate; FT-IR, FT -Raman, NMR, NBO, HOMO-LUMO and DFT studies
The Fourier transform infrared (FTIR) and FT - Raman spectra of 2, 6-dichlorophenyl isocyanate have been recorded in the liquid state. The molecular geometry, vibrational frequencies, and atomic charges have been calculated by using density functional theory (DFT) calculation (B3LYP) with 6-311+G(d,p) and 6-311++G(d,p) basis sets. Simulated FTIR and FT - Raman spectra for 2, 6-dichlorophenyl isocyanate showed good agreement with the observed spectra. The calculated HOMO and LUMO energies show that charge transfer occurs within the molecule. The molecular stability and bond strength were investigated by applying the natural bond orbital (NBO) analysis and electrostatic potential (ESP). The isotropic chemical shift computed by 1H and 13C nuclear magnetic resonance (NMR) chemical shifts of the 2, 6-dichlorophenyl isocyanate calculated using the gauge invariant atomic orbital (GIAO) method also shows good agreement with experimental observations.

Optimised layered approach on congestion control with efficient energy and QOS improvement for wireless network
Internet is widely used in the fast growing world and there are many limitations in the network. There are two main failures that occur in the network they are wireless packet loss and congestion. The performance of SCTP in wireless network is considered as the active area. Finding the failure in the wireless network is very important and it is analysed in this paper. So in this paper the route is established by on demand routing technique in which many features like the energy of the node, location, bandwidth of the packet are analysed. So when the packets need to be send it analyses all the features and establishes the route with the efficient node that has one hop count by using the SCTP transport protocol. On transmitting the packets some energy from the node gets reduced so there is a high chance of congestion since the capacity of the node is reduced. This can be avoided by the proactive approach by reducing the traffic send by the source when the node level reaches threshold. By using the multi-homing technique in the SCTP approach the packets can be sending till the alternate route is re-established. Thus the packet loss rate and end-end delay is reduced and QOS is increased in the system.

Determine Sugarcane harvester field efficiency using global positioning system (GPS) data
Population growth and increase need greater utilization of resources such as food, water, soil, energy, machinery, manpower and other inputs lead to use them more than last era for earn more production. And better management methods; minimize operational cost to reach maximum profitability more attention is placed on agricultural systems. Since sugar cane is one of the major plants under cultivation in the septet agro industry reach to 84000 hectares in Khuzestan province and a case study is Karun agro industry that has total area 40000 hectare which currently 25000 hectare is arable. On the other hand one of the most expenses in each agricultural production systems is machinery cost, increase in efficiency of farm machinery can affect on production costs. As regards in most cases manager of agricultural mechanization unit don’t know exactly how can use the machinery in different farm operation (tillage, planting, intercultural and harvest) at optimum condition and detect factors that lead to decrease in field efficiency. So consideration of farm machinery field efficiency is necessary. Between farm Operation, sugar cane harvesting is more important because have high volume of work. The purpose of this article is to show how Global Positioning Systems, or GPS data, can provide very useful information about the efficiency of sugarcane harvester. In the past, calculation of field efficiency was very difficult, time consuming, and required someone with a stopwatch on-site during operation. But now by combining GPS data in other software like: Garmin Map source, Google earth and Arch map can be used to produce maps of navigation and obtain farm machinery management factors like field efficiency, material capacity and field index that were calculate for this study 69%, 51.5 ton/hour and 63% respectively.
