Despite the popularity of the idea in American culture that self-enhancement confers psychological benefits, the evidence for this idea is mixed. In the present research, we tested the contention that overly positive self-assessments could lead to psychological distress. In two correlational studies (Studies 1 and 2), we addressed some previous problems related to the measurement of self-enhanc...

sometimes the need for non-circular ducts arises in many heat transfer applications because of lower pressure drop of non-circular cross section such as square duct compared to circular tube, particularly in compact heat. but square cross section has poor heat transfer performance and it is expected that using a nanofluid as a new heat transfer media may improve the heat transfer performance of...

Subjects with central field loss (CFL) individually selected enhancement parameters to improve visibility of static video images. The effect of enhancement on performance and on perceived quality of motion video was assessed. Performance, e.g. recognition of visual details, was assessed by having subjects answer questions regarding visual information contained in the video motion segments that ...

Two studies examined the interactive effects of different visual imagery perspectives and narcissism on motor performance. In both studies participants completed the Narcissistic Personality Inventory (NPI-40: Raskin & Hall, 1979) and were assigned to either an internal visual imagery or external visual imagery group. Participants then performed a motor task (dart throwing in Study 1 and golf p...

The main purpose of image enhancement is to bring out detail that is hidden in an image or to increase contrast in a low contrast image. Image enhancement techniques provide a multitude of choices for improving the visual quality of images. Appropriate choice of such techniques is greatly influenced by the imaging modality, task at hand and viewing conditions. This paper analyses the performanc...

Fingerprint image enhancement is an essential preprocessing step in fingerprint recognition applications. In this paper, a Separable Gabor filter with Bresenham (SGB) is introduced for fast fingerprint enhancement. A Curve Mask Gabor (CMG) is designed to improve the performance of SGB. Experiments are performed on FVC2004. Results indicate that the SGB can significantly reduce computational com...

This paper analyzes the performance of various single channel speech enhancement systems when they are applied to automatic speech recognition (ASR) systems as a preprocessor. Until now the researches on speech enhancement algorithms have focused on improving the perceptual quality of speech signal. However, it has not been verified yet whether the improvements of the perceptual quality also in...

An experiment is reported that extends earlier work on the enhancement of eye pointing in 2D environments, through the addition of a zoom facility, to its use in virtual 3D environments using a similar enhancement. A comparison between hand pointing and eye pointing without any enhancement shows a performance advantage for hand based pointing. However, the addition of a ‘fly’ or ‘zoom’ enhancem...

The present study investigated comparatively the impact of two types of input enhancement (i.e. textual vs. compound enhancement) on developing grammar ability in Iranian EFL setting. Sixty-five female secondary high school students were selected as a homogenous sample out of about a 100-member population based on Nelson language proficiency test. Then, their grammar ability was measured based ...
