Optimal detectors based on time-frequency/time-scale representations (TFRs/TSRs) admit a representation in terms of a bank of spectrograms/scalograms that yields a large class of detectors. These range from the conventional matched lter to the more complex higher-rank detectors ooering a superior performance in a wider variety of detection situations. In this paper, we optimize this complexity ...

I described the tactile-stimulated startle response (TSR) of wood frog (Rana sylvatica), bullfrog (Rana catesbeiana), and American toad (Bufo americanus) tadpoles. One purpose was to rank species in terms of maximum acceleration performance. Also, I tested whether anatomical indicators of performance potential were predictive of realized performance. TSRs were elicited in a laboratory setting, ...

When people have to choose a creative solution from several ideas tackle problem, they tend select mainstream at the expense of ideas. In current research, we examined effect rank-ordering strategy on idea selection performance by comparing three different strategies: choosing (i.e., stepwise selecting most idea), elimination removing least and paired comparison making series choices pairs idea...

performance management is one of the special topics of strategic human resource management that is a useful tool for improving the performance of the employees and the organization. if the performance management is designed and implemented in the organization with its requirements and prerequisites, it can identify some of the organization’s problems to provide feasible strategies to solve them...

Unsupervised aggregation of independently built univariate predictors is explored as an alternative regularization approach for noisy, sparse datasets. Bipartite ranking algorithm Smooth Rank implementing this approach is introduced. The advantages of this algorithm are demonstrated on two types of problems. First, Smooth Rank is applied to two-class problems from bio-medical field, where ranki...

The study of various countries rail transportation indicators is an appropriate criterion for evaluating the existing performance of Iranian railways. The experiences of other countries can be used to improve the efficiency of Iran’s rail transportation. At the beginning of the study, in order to compare the Iranian railway performance with railways of other countries, various efficiency indica...

Non-uniformly distributing documents in an unstructured peer-to-peer (P2P) network has been shown to improve both the expected search length and search accuracy, where accuracy is defined as the size of the intersection of the documents retrieved by a constrained, probabilistic search and the documents that would have been retrieved by an exhaustive search, normalized by the size of the latter....
