: Many image features are proved to be good candidates for recognition. Among them are edges, lines, corners, junctions or interest points in general. Importance of corner detection in digital images is increasing with increasing work in computer vision in imagery. One of the most promising techniques is the one based on Harris corner detection method. This work describes different approaches t...

Session I 9:30 – 10:45 AM Andrew Miles: Roanoke College Department of Philosophy Good, Evil and Well-being: Sam Harris’ Scientific Approach to Ethics One of the most controversial debates in ethics is how to define Good and Evil. Do “good” actions necessarily adhere to commandments set by a God? Or are there many different, equally valid definitions based on cultural norms? Neuroscientist and a...

Corner detection is a fundamental step in image processing, and it takes an important role in target tracking, image stitching and three-dimension reconstruction. Harris algorithm is widely used in corner detection for simple calculation and its detection result is not affected by image rotation and light intensity changes. Harris algorithm uses integral differential mask to extract the image g...

A φ-irreducible and aperiodic Markov chain with stationary probability distribution will converge to its stationary distribution from almost all starting points. The property of Harris recurrence allows us to replace “almost all” by “all,” which is potentially important when running Markov chain Monte Carlo algorithms. Full-dimensional Metropolis–Hastings algorithms are known to be Harris recur...

In 1841, T. W. Harris published "A Report on the Insects of Massachusetts, Injurious to Vegetation," a seminal work in North American Entomology and one of the first New World publications to describe Lepidoptera species. Although appearing in several subsequent editions, the eight family-group names proposed by Harris were largely overlooked. In summarizing Harris' family-group names, we show ...

According to the rotational invariance of Harris corner detector and the robustness of Sift descriptor. An improved Harris-Sift corner descriptor was proposed. At first, the algorithm given multi-scale strategy to Harris corner, improved corner counting method and removed redundant points at the same time, then, the corner was directly applied to low-pass Gaussian filter image. Based on the his...

Harris (2006) recently proposed a new elemental model of the processes involved in associative learning. Although Harris explicated all relevant mathematical and conceptual details of the model in his article, implementing a computer simulation of his model requires considerable programming expertise and work. We therefore present the Harris model simulator (HMS), a MATLAB simulator of Harris's...

عملگر پلاسمایی از کارآمدترین و مطمئن‌ترین روش‌های کنترل فعال جریان سیال شناخته می‌شود. یکی از مدل‌های عددی برای شبیه‌سازی اثر عملگر بر جریان سیال، مدل سوزن-هوانگ است که در آن با حل دو معادله بیضوی برای پتانسیل الکتریکی و غلظت شارژ، اثر عملگر به صورت ترم‌های چشمه به معادلات ناویر-استوکس افزوده می‌گردد. در این پژوهش شرط مرزی جدیدی برای توزیع شارژ بر روی سطح دی‌الکتریک پیشنهاد می‌شود که ارتباطی را...

در این مقاله با استفاده از یک مدل الکتروستاتیک ارتقایافته، اثر عملگر پلاسمای دی‌بی‌دی بر جریان روی یک ایرفویل مطالعه شده است. این مدل اجازه می‌دهد که بدون نیاز به داده‌های تجربی رفتار عملگر پلاسما در ولتاژها و فرکانس‌های مختلف با دقت مطلوبی پیش‌بینی شود. جریان هوا در رژیم تراکم‌ناپذیر بوده و عدد رینولدز جریان بیش از نیم میلیون است. مدل الکتروستاتیک با حل میدان پتانسیل الکتریکی و غلظت پلاسما، ...
