This article focuses on the estimation of population proportion when the study variable is sensitive in nature. Two implicit randomized response techniques are proposed where the unrelated trait can be chosen subjectively. In addition to unbiased estimation of population proportion and variance, an empirical study is conducted to inspect the relative efficiency facet of the proposed techniques....

the purpose of this study was to investigate the impact of blended learning and multimedia software on iranian esp students' vocabulary learning. to this end, 120 iranian esp learners were assigned to two groups: the experimental and control groups. the experimental group received instructions through multimedia software while the control group received traditional instructions. the data were c...

Expander2 is a flexible multi-purpose workbench for interactive term rewriting, graph transformation, theorem proving, constraint solving, flow graph analysis and other procedures that build up proofs or other rewrite sequences. Moreover, tailor-made interpreters display terms as two-dimensional structures ranging from trees and rooted graphs to a variety of pictorial representations that inclu...

These movie files are split into series of image files that contain full frames (odd and even lines) or interpolated fields. We have developed interactive and fully automated procedures for batch-processing these image files. The processed files are converted into new movie files. The processed movies, and result reports of the investigation are stored on CD-ROM and videotape for use in court. ...

A variety of digital change detection techniques has been developed in the past three decades, ranging from interactive to automated procedures, from preto post-classification methods, from simultaneous to comparative analysis, from change extraction to change labelling, from bi-temporal to multitemporal methods, from spectral to spatial techniques and, last but not least, from pixel-based to o...

Interventional MRI (IMRI) has entered into a new stage in which computer-based techniques play an increasing role in planning, monitoring, and controlling the procedures. The use of interactive imaging, navigational image guidance techniques, and image processing methods is demonstrated in various applications. The integration of intraoperative MRI guidance and computer-assisted surgery will gr...

In the paper we consider application of techniques of knowledge discovery in databases (KDD) to spatially referenced data. We propose to combine such techniques with various methods of interactive classification of spatial objects supported by map displays. Maps help both to prepare source data for KDD procedures and to interpret results of their application. The latter function is realized thr...

Policy relevant conclusions emerge when meta-analytic techniques are used to achieve consensus out of the inconsistencies found in individual research studies. Extensive search procedures located 120 school-based drug prevention programs that evaluated success on self-reported drug use measures. Hypothesis tests were made of an a priori classification scheme for the type of program. Six types o...
