A new chaos-based image-encryption and compression algorithm
( Hindawi Publishing Corporation , 2012 , Article)We propose a new and efficient method to develop secure image-encryption techniques. The new algorithm combines two techniques: encryption and compression. In this technique, a wavelet transform was used to decompose the ... -
A sensitivity analysis approach to identify key environmental performance factors
( Hindawi Publishing Corporation , 2014 , Article)Life cycle assessment (LCA) is widely used in design phase to reduce the product's environmental impacts through the whole product life cycle (PLC) during the last two decades. The traditional LCA is restricted to assessing ... -
Automatic prediction of age, gender, and nationality in offline handwriting
( Hindawi Publishing Corporation , 2014 , Article)The classification of handwriting into different categories, such as age, gender, and nationality, has several applications. In forensics, handwriting classification helps investigators focus on a certain category of ... -
Cross-Layer Optimal Rate Allocation for Heterogeneous Wireless Multicast
( Hindawi Publishing Corporation , 2009 , Article)Heterogeneous multicast is an efficient communication scheme especially for multimedia applications running over multihop networks. The term heterogeneous refers to the phenomenon when multicast receivers in the same session ... -
Optimal inconsistency repairing of pairwise comparison matrices using integrated linear programming and eigenvector methods
( Hindawi Publishing Corporation , 2014 , Article)Satisfying consistency requirements of pairwise comparison matrix (PCM) is a critical step in decision making methodologies. An algorithm has been proposed to find a new modified consistent PCM in which it can replace the ... -
Optimization and Prediction of Mechanical and Thermal Properties of Graphene/LLDPE Nanocomposites by Using Artificial Neural Networks
( Hindawi Publishing Corporation , 2016 , Article)The focus of this work is to develop the knowledge of prediction of the physical and chemical properties of processed linear low density polyethylene (LLDPE)/graphene nanoplatelets composites. Composites made from LLDPE ... -
Text-dependent writer identification for arabic handwriting
( Hindawi Publishing Corporation , 2012 , Article)This paper proposes a system for text-dependent writer identification based on Arabic handwriting. First, a database of words was assembled and used as a test base. Next, features vectors were extracted from writers' word ...
