Asymmetric color image encryption and compression based on discrete cosine transform in Fresnel domain
In this paper, a new asymmetric method is presented to encrypt and compress color images using discrete cosine transform in Fresnel domain.First, the input color image is decomposed into three channels: red, green and blue.Each channel image is converted into phase image and bonded with an amplitude mask followed by Fresnel transform to get the com

Measuring burnout and work engagement: Factor structure, invariance, and latent mean differences across Greece and the Netherlands
This study examines the factor structure and invariance of the instruments measuring burnout (Maslach Burnout Inventory - General Survey / MBI-GS) and work engagement (Utrecht Work Engagement Scale / UWES) in a sample of Dutch (N = 162) and Greek (N = 206) employees.Confirmatory factor analyses in both samples supported the superiority of the propo
