Context-awareness is viewed as one of the most important aspects in the emerging pervasive computing paradigm. Mobile context-aware applications are required to sense and react to changing environment conditions. Such applications, usually, need to recognize, classify and predict context in order to act efficiently, beforehand, for the benefit of the user. In this paper, we propose a mobility p...

by KAVITHA ANANDAN (Under the Direction of Hamid R. Arabnia) ABSTRACT One among the non-exhaustive list of applications where image processing is used is Nanotechnology. To visualize and characterize the nanostructures, high resolution Scanning Electron Microscope (SEM) and Atomic Force Microscopy (AFM) are ideally used. One of the crucial steps in image processing the nanostructures is image s...

High dimensional directional data is becoming increasingly important in contemporary applications such as analysis of text and gene-expression data. A natural model for multi-variate directional data is provided by the von Mises-Fisher (vMF) distribution on the unit hypersphere that is analogous to multi-variate Gaussian distribution in R. In this paper, we propose modeling complex directional ...

Abstract In order to achieve ship target detection based on remote sensing images in complex backgrounds, this paper proposes a algorithm YOLO V5. First, the improved Kmeans is used cluster data set, DIOU_loss for candidate frame selection strategy, and finally channel attention mechanism introduced. The experimental results show that under same conditions, network has slight decrease speed com...

آگاهی از میزان تاج‌پوشش درختان در مناطق شهری به‌علت تأثیرات آن کاهش آلودگی‌‌های هوا، آلودگی صوتی، جلوگیری باد، ذخیرة نزولات آسمانی، و کنترل رواناب‌های بسیار ضروری است. ازآن‌جا‌که استخراج با روش‌های دستی وقت‌گیر پرهزینه است، تکنیک‌های سنجش دور می‌توانند ابزار مناسبی برای تأمین این داده‌ها باشند. طبقه‌بندی شیء‌پایه، انتخاب پارامترهای بهینة قطعه‌بندی، به‌ویژه پارامتر مقیاس، اهمیت بسیاری دارد معمول...

Manufacturing enterprises will accumulate a large number of manufacturing instances as they run and develop. Being able to excavate reuse the instance resources reasonably is one most effective ways improve support innovation. To determine object scientifically raise flexibility, novel system for discovery typical process route based on information entropy PSO-Kmeans clustering algorithm propos...
