Abstract: A array of the azimuthally averaged range-profile vectors and the inter-class and intra-class divergence matrixesare constructed iwth many frames of the high resolution range profiles which result from radar echoes of airplanes. Takingthe methods of whitening transformation and SVD produces a system of subspace vectors for target recognition. Where-upon, a template library for target recognition is built by the projection of a class-mean vector made from the radar dataonto the subspace for recognition. By Euclidean distance, a comparison is made between the above projection and eachtemplate in the library, to decide which class the target belongs to. Finally, simulations with the experimental radar dataarte given to show that the proposed method is robust to variation in azimuth and immune to additive Gaussian noisewhen SNr≥5dB.

“Absolutely riveting reading: A master piece.” (Sir Alan Cottrell) No more words could be said for a book already commented by another eminent scientist of the discipline, who is also a celebrated master in the understanding of materials and founding and growth of the science in the last half of a century at the end of the ten millennia since the use of fabrication and modification of man-made materials. We had the fortune and honour of receiving the earliest copies of the book in China during our meeting with the author either in England (Ko) or during the author’s visit to China as a Foreign Member of the Chinese

A selective method has been developed for the extraction chromatography of aluminium(Ⅲ) and its separation from several metal ions with a chromatographic column containing N-n-octylaniline ( a liquid anion exchanger) coated on silanized silica gel as a stationary phase. The aluminium(Ⅲ) was quantitatively extracted with the 0. 065 mol / L N-n-octylaniline in 0. 013 to 0. 05 mol / L sodium succinate at a flow rate of 1. 0 mL / min. The extracted metal ion has been recovered by eluting with 25. 0 mL of 0. 05 mol / L hydrochloric acid and estimated spectrophotometrically with aurintricarboxylic acid. The effects of the acid concentration,the reagent concentration,the flow rate and the eluting agents have been investigated. The log-log plots of distribution coefficient ( K d ( Al(Ⅲ) ) ) versus N-n-octylaniline concentration in 0. 005 and 0. 007 mol / L sodium succinate gave the slopes of 0. 5 and 0. 7 respectively and showed the probable composition of the extracted species was 1∶ 1 ( metal to amine ratio ) and the nature of extracted species was [rr' NH + 2 Al succinate 2 ] org. . The extraction of aluminium(Ⅲ) was carried out in the presence of various ions to ascertain the tolerance limit of individual ions. Aluminium(Ⅲ) has been separated from multicomponent mixtures,pharmaceutical samples and synthetic mixtures corresponding to alloys. A scheme for mutual separation of aluminium(Ⅲ) ,indium(Ⅲ) ,gallium(Ⅲ) and thallium(Ⅲ) has been developed by using suitable masking agents. The method is fast,accurate and precise.

A standing rossby wave of wavelength 30°longitude with a finite amplitude along the meridional direction is superimposed on the zonal mean component of the monsoon flow and the stability of such a flow is examined by a quasi-geostrophic *** well as by a quasi-geostrophic combined barotropic and baroclinic model on a beta plane centered at 18°N latitude. It is found that the growth of synoptic scale disturbance increases with the amplitude of the meridional wind. The barotropic stability analysis at 700 hPa pressure level shows that there is a critical value (Umaz=11 m/s) of the maximum mean zonal wind below which the computed disturbance moves to the west due to the wave-wave superposition. For maximum mean zonal wind greater that 11m /s, the westerly wind dominates and the disturbance moves to the east. In another analysis the stability of the zonally asymmetric basic now is studied with a combined barotropic-barotropic model where cumulus heating is included. The growth rate, intensity, horizontal scale and the westward velocity of computed disturbances reasonably agree with those of observed monsoon disturbances. The fastest growing mode has a horizontal wavelength of 2000 kms and the e-folding time is about 3 days,when the meridional amplitude of the rossby wave is 4m/ s at 700 hPa pressure level. When cumulus heating is included in the analysis the intensity of geopotential perturbation at 700 hPa disturbance is -304 m2 / s2. Energy calculations show that the kinetic energy of the mean zonal flow is the main source of energy for the perturbation to *** is also t'ound that the contribution of the kinetic energy of the basic rossby wave to the growth of perturbation is more in comparison to the available potential energy.

This paper proposes the charge plasma based dual electrode doping-less tunnel FET （DEDLTFET）. The paper compares the device performance of the conventional doping-less TFET （DLTFET） and doped TFET （DGTFET）. DEDLTEFT gives the superior results with high ON state current （/ON - 0.56 mA/um）, ION/IoFv ratio - 9.12 ×1013 and an average subthreshold swing （AV-SS -- 48 mV/dec）. The variation of different device parameters such as channel length, gate oxide material, gate oxide thickness, silicon thickness, gate work function and temperature variation are done and compared with DLTFET and DGTFET. Through the extensive analysis it is found that DEDLTFET shows the better performance than the other two devices, which gives the indication for an excellent future in low power applications.
