An Autonomic Auto-scaling Controller for Cloud Based Applications

Author 1: Jorge M. Londoño-Peláez Author 2: Carlos A. Florez-Samur

One of the key promises of Cloud Computing is elasticity – applications have at their disposal a very large pool of resources from which they can allocate whatever they need. For any fair-size application the amount of resources is significant and both overprovisioning and under provisioning have a negative impact… Read full abstract & cite →

Review on Aspect Oriented Programming

Author 1: Heba A. Kurdi

Aspect-oriented programming (AOP) has been introduced as a potential programming approach for the specification of nonfunctional component properties, such as fault-tolerance, logging and exception handling. Such properties are referred to as crosscutting concerns and represent critical issues that conventional programming approaches could not modularize effectively leading to a complex code… Read full abstract & cite →

Fingerprint Image Segmentation Using Haar Wavelet and Self Organizing Map

Author 1: Sri Suwarno Author 2: Subanar Author 3: Agus Harjoko Author 4: Sri Hartati

Fingerprint image segmentation is one of the important preprocessing steps in Automatic Fingerprint Identification Systems (AFIS). Segmentation separates image background from image foreground, removing unnecessary information from the image. This paper proposes a new fingerprint segmentation method using Haar wavelet and Kohonen’s Self Organizing Map (SOM). Fingerprint image was decomposed… Read full abstract & cite →
