Remote sensing techniques can decrease pest monitoring costs in orchards. To evaluate the feasibility of detecting spider mite damage in orchards, we measured visible and near infrared reflectance of 1153 leaves and 392 canopies in 11 peach orchards in California. Pairs of significant wavelengths, identified by Partial Least Squares regression, were combined into normalized difference indices. ...

results of damage prediction in buildings can be used as a useful tool for managing and decreasing seismic risk of earthquakes. in this study, damage spectrum and c4.5 decision tree algorithm were utilized for damage prediction in steel buildings during earthquakes. in order to prepare the damage spectrum, steel buildings were modeled as a single-degree-of-freedom (sdof) system and time-history...

This study developed a rapid assessment algorithm for post-hurricane forest damage estimation using moderate resolution imaging spectroradiometer (MODIS) measurements. The performance of five commonly used vegetation indices as post-hurricane forest damage indicators was investigated through statistical analysis. The Normalized Difference Infrared Index (NDII) was identified as the optimal dama...

Damage evolution of rectangular concrete-filled steel tube (RCFT) members, connections, and frames as documented in experimental tests was investigated in this research. Based on the experimental data, appropriate limits states for RCFTs were defined at different levels of loading. For each limit state, the performance of the specimens was judged with the use of damage indices. The report also ...

In this study the slopes of the QRS complex are evaluated for determination of the degree of myocardial damage in chronic chagasic patients. Previous studies have demonstrated the ability of the slope indices to reflect alterations in the conduction velocity of the cardiac impulse. Results obtained in the present study show that chronic chagasic patients have significantly flatter QRS slopes as...

OBJECTIVES To determine the most appropriate indices to evaluate the disease activity and damage in patients with sytemic lupus erythematosus (SLE). METHODS A systematic literature search was performed to identify validation studies of indices used to evaluate disease activity and damage. We collected information for each instrument on every aspect of validation including feasibility, reliabi...
