Improvement of User's Accuracy Through Classification of Principal Component Images and Stacked Temporal Images

引用

Geo-Spatial Information Science 2010年第4期13卷 243-248页

作者： Nilanchal Patel Brijesh kumar kaushal Department of Remote Sensing Birla Institute of Technology Mesra

The classification accuracy of the various categories on the classified remotely sensed images are usually evaluated by two different measures of accuracy, namely, producer＇s accuracy （PA） and user＇s accuracy （UA）. The PA of a category indicates to what extent the reference pixels of the category are correctly classified, whereas the UA of a category represents to what extent the other categories are less misclassified into the category in question. Therefore, the UA of the various categories determines the reliability of their interpretation on the classified image and is more important to the analyst than the PA. The present investigation has been performed in order to determine if there occurs improvement in the UA of the various categories on the classified image of the principal components of the original bands and on the classified image of the stacked image of two different years. We performed the analyses using the IRS LISS Ⅲ images of two different years, i.e., 1996 and 2009, that represent the different magnitude of urbanization and the stacked image of these two years pertaining to Ranchi area, Jharkhand, India, with a view to assessing the impacts of urbanization on the UA of the different categories. The results of the investigation demonstrated that there occurs significant improvement in the UA of the impervious categories in the classified image of the stacked image, which is attributable to the aggregation of the spectral information from twice the number of bands from two different years. On the other hand, the classified image of the principal components did not show any improvement in the UA as compared to the original images.

MicroProteins are small,5-15-kDa single-domain proteins that are evolutionarily related to multi-domain proteins with sequence homology(Eguen et al.,2015).The single domain of microProteins is often a protein-protein interaction(PPI)-domain,through which they can interact with their multi-domain protein targets(Figure 1).The first experimental insight that microProteins exist and how they act came from the identification of the regulatory feedback mechanism of class III homeodomain-leucine zipper(HD-ZIPIII)transcription factors by LITTLE ZIPPER(ZPR)microProteins(Wenkel et al.,2007;Kim et al.,2008).In Arabidopsis,the LITTLE ZIPPER microProtein family consists of four members(ZPR1-4)containing only a leucine zipper *** HD-ZIPIII transcription factor REVOLUTA directly transcriptionally upregu-lates multiple ZPR *** proteins physically interact with their HD-ZIPIII targets and suppress their DNA binding ability.

Estimation of composite load model with aggregate induction motor dynamic load for an isolated hybrid power system

引用

Frontiers in Energy 2015年第4期9卷 472-485页

作者： Nitin kumar SAXENA Ashwani kumar sharma Deptment of Electrical Engineering NIT Kumkshetra Haryana 136119 India

It is well recognized that the voltage stability of a power system is affected by the load model and hence, to effectively analyze the reactive power compensation of an isolated hybrid wind-diesel based power system, the loads need to be considered along with the generators in a transient analysis. This paper gives a detailed mathematical modeling to compute the reactive power response with small voltage perturbation for composite load. The composite load is a combination of the static and dynamic load model. To develop this composite load model, the exponential load is used as a static load model and induction motors （IMs） are used as a dynamic load model. To analyze the dynamics of IM load, the fifth, third and first order model of IM are formulated and compared using differential equations solver in Matlab coding. Since the decentralized areas have many small consumers which may consist large numbers of IMs of small rating, it is not realistic to model either a single large rating unit or all small rating IMs together that are placed in the system. In place of using a single large rating IM, a group of motors are considered and then the aggregate model of IM is developed using the law of energy conservation. This aggregate model is used as a dynamic load model. For different simulation studies, especially in the area of voltage stability with reactive power compensation of an isolated hybrid power system, the transfer function AQ/AV of the composite load is required. The transfer function of the composite load is derived in this paper by successive derivation for the exponential model of static load and for the fifth and third order IM dynamic load model using state space model.

Antioxidant and modulatory role of Chlorophytum borivilianum against arsenic induced testicular impairment

Journal of Environmental Sciences 2012年第12期24卷 2159-2165页

作者： Garima sharma Madhu kumar Cell and Molecular Biology Laboratory Department of ZoologyCentre for Advanced studiesUniversity of RajasthanJaipur 302055India

Arsenic has a suppressive influence on spermatogenesis and induces impairment in male reproductive system due to oxidative stress. The present study was aimed to test the arsenic induced toxicity and protection by Chlorophytum borivilianum. The effect of sodium arsenite （4 mg/（kg body weight （bw）.day）） via double distilled water without or with C. borivilianum （800 mg/（kg ***）） was evaluated in Swiss albino mice for 30 days. The radical scavenging activity of the aqueous C. borivilianum root extract was measured using DPPH （1,1-diphenyl-2-picryl hydrayzyl） radical. Qualitative assessment of various cell types in the testis, sperm count and motility, testicular activity of lipid peroxidation （LPO）, reduced glutathione （GSH）, acid and alkaline phosphatase, cholesterol and serum testosterone were monitored. Arsenic treatment showed a significant increase in LPO, acid and alkaline phosphatase, cholesterol and decrease in sperm count, sperm motility, GSH and serum testosterone. Combined treatment showed significant decrease in LPO, acid and alkaline phosphatase, cholesterol and elevation in sperm count, sperm motility, GSH and serum testosterone. Testicular histopathology showed that C. borivilianum had reduced degeneration of germ cell in the seminiferous tubules and loss of sperms induced by arsenic intoxication. The results thus led us to conclude that administration of C. borivilianum root extract is found to be protective against arsenic induced toxicity.
