Over the last few years several authors have presented various methods to assign mathematical descriptors to DNA sequences in order to quantitatively compare the sequences and determine similarities and dissimilarities between them. The plethora of different methods used have made it necessary to compare them and determine which one(s), if any, best meet the needs required to characterize DNA s...

Nonprofit board members and administrators have a responsibility to 1) ensure that their organization’s return on investment (ROI) in fundraising is reasonable through good internal management practices, and 2) communicate to their constituents and the general public that fundraising is an investment in achieving the goals, objectives and anticipated outcomes described in the organization’s str...

Eye gaze detection under challenging lighting conditions is a non-trivial task. Pixel intensity and the shades around the eye region may change depending on the time of day, location, or due to artificial lighting. This paper introduces a lighting-adaptive solution for robust eye gaze detection. First, we propose a binarization and cropping technique to limit our region of interest. Then we dev...

Monitoring eye movement offers insights into visual perception, as well as the users associated attention mechanisms and cognitive processes. This paper presents the results of an empirical study that investigated the impact of differing multimedia presentation frame rates on the user perceptual experience, as reflected through video eye path data. Results show that varying frame rates do not a...

Recent advances in real-time magnetic resonance imaging (rtMRI) make possible the following study of post-dorsal coarticulatory effects on lateral approximants in running speech. As the MRI is particularly well-suited for investigating pharyngeal articulations, it was capable of capturing perseverative coarticulation from a low central vowel to the immediately following syllable-initial lateral...

The size of a lesion is a feature often used in computer-aided detection systems for classification between benign and malignant lesions. However, size of a lesion presented by its area might not be as reliable as volume of a lesion. Volume is more independent of the view (CC or MLO) since it represents three dimensional information, whereas area refers only to the projection of a lesion on a t...

Identification and tracking of a moving object using computer vision techniques is important in robotic surveillance. In this paper, an adaptive colour filteringmethod is introduced for identifying and tracking a moving object appearing in image sequences. This filter is capable of automatically identifying the most salient colour feature of the moving object in the image and using this for a r...

In this paper we examine the reconstruction of a local region of a non-rigidly moving heart with unknown motion, using methods of reconstruction of rigid objects and without using (electrocardiogram) ECG-information. The reconstruction procedure chosen is based on the well-known Feldkamp filtered-backprojection algorithm. It reconstructs the volume of a rigid object from a reduced set of projec...

Although many companies have spent a great deal of money to adopt CRM (Customer Relationship Management) technologies, many have not seen satisfactory returns on their CRM installations. One of the reasons for such dissatisfaction and low ROI may be the lack of a comprehensive approach to evaluating the impact of CRM technologies, which are very different from traditional cost-cutting and quali...
