in this paper we introduce a simple, computationally inxepentsive, adaptive recursive structure for enhancing bandpass signals highly corrupted by broad-band noise. this adaptive algorithm, enhancing input signals, enables us to estimate the center frequency and the bandwidth of the input signal. in addition, an important feature of the proposed structure is that the conventional bias existing ...

This paper presents an updated and systematic overview of the recent development in studies on nucleation process in diamond CVD. The nucleation mechanisms are discussed, and the nucleation enhancement methods developed to date are summarized. The effects of surface conditions and deposition parameters on the surface nucleation are described. Finally, a brief description of theoretical and mode...

Lineament enhancement is an important subject in image,processing. In this paper a simple but powerful lineament enhancement technique is presented, which consists of a unique differentiation and a directional filtering. A preprocessing and postprocessings are also described. And some results from LANDSAT images are selected and exhibited for comparison of the effects of several parameters in e...

Ubiquitous cognitive biases hinder optimal decision making. Recent calls to assist decision makers in mitigating these biases—via interventions commonly called “nudges”—have been criticized as infringing upon individual autonomy. We tested the hypothesis that such “decisional enhancement” programs that target overt decision making—i.e., conscious, higher-order cognitive processes—would be more ...

In image enhancement various enhancement schemes have been used for enhancing which includes gray scale manipulation, filtering and Histogram Equalization (HE). Histogram equalization techniques using fuzzy logic is one of the unique image enhancement technique. It became a popular technique for contrast enhancement because this method is simple and effective. In the latter case, preserving the...

The present study is an attempt to examine the psychological processes of noticing, retrieval, and generation their possible contribution process vocabulary learning retention among intermediate students. research method was experimental. One hundred twenty students were randomly assigned into four groups, namely Noticing through Input enhancement (n=30), Enhancement plus Input-Based Reviewing ...

This study was inspired by VanPatten and Uludag’s (2011) study on the transferability of training via processing instruction to output tasks and Mori’s (2002) work on the development of talk-in-interaction during a group task. An interview was devised as the pretest, posttest, and delayed posttest to compare four intervention types for teaching the simple past passive: traditional intervention ...

Performance of the linear models, widely used within the framework of adaptive line enhancement (ALE), deteriorates dramatically in the presence of non-Gaussian noises. On the other hand, adaptive implementation of nonlinear models, e.g. the Volterra filters, suffers from the severe problems of large number of parameters and slow convergence. Nonetheless, kernel methods are emerging solutions t...

An important property of electromagnetic fields, which arises from the interaction between fields and chiral molecules, is called optical chirality. By enhancing this field property, while maintaining constant input power, we are able to increase absorption of circularly polarized light by chiral molecules of a certain handedness. This enhancement is achieved through the use of achiral plasmoni...
