Skew Detection/Correction and Local Minima/Maxima Techniques for Extracting a New Arabic Benchmark Database

Author 1: Husam Ahmed Al Hamad

We propose a set of techniques for extracting a new standard benchmark database for Arabic handwritten scripts. Thresholding, filtering, and skew detection/correction techniques are developed as a pre-processing step of the database. Local minima and maxima using horizontal and vertical histogram are implemented for extracting the script elements of the… Read full abstract & cite →

Standard Positioning Performance Evaluation of a Single-Frequency GPS Receiver Implementing Ionospheric and Tropospheric Error Corrections

Author 1: Alban Rakipi Author 2: Bexhet Kamo Author 3: Shkelzen Cakaj Author 4: Algenti Lala

This paper evaluates the positioning performance of a single-frequency software GPS receiver using Ionospheric and Tropospheric corrections. While a dual-frequency user has the ability to eliminate the ionosphere error by taking a linear combination of observables, a single-frequency user must remove or calibrate this error by other means. To remove… Read full abstract & cite →

A Minimum Number of Features with Full-Accuracy Iris Recognition

Author 1: Ibrahim E. Ziedan Author 2: Mira Magdy Sobhi

A minimum number of features for 100% iris recognition accuracy is developed in this paper. Such number is based on dividing the unwrapped iris into vertical and horizontal segments for a single iris and only vertical segments for dual-iris recognition. In both cases a simple technique that regards the mean… Read full abstract & cite →

Apply Metaheuristic ANGEL to Schedule Multiple Projects with Resource-Constrained and Total Tardy Cost

Author 1: Shih-Chieh Chen Author 2: Ching-Chiuan Lin

In this paper the multiple projects resource-constrained project scheduling problem is considered. Several projects are to be scheduled simultaneously with sharing several kinds of limited resources in this problem. Each project contains non-preemptive and deterministic duration activities which compete limited resources under resources and precedence constraints. Moreover, there are the… Read full abstract & cite →
