introduction: laryngeal dysfunction may be divided into three categories; organic, neurologic and functional disorders. dysphonia and hoarseness are the most common symptoms and, in some cases, the only signs of laryngeal dysfunction. in differential diagnosis of any type of chronic hoarseness, a neoplastic process must be considered and, thus continuous light video laryngoscopy can provide imp...

Coastal waters represent the commingling of offshore marine and terrestrial surface source waters and therefore are naturally complex and variable. Our long term goal is to establish observational and modeling approaches to predict sources and scales of variability in the source waters, particularly those related to land use activities in upstream watersheds, from observations and measurements ...

In this paper, we describe an innovative project where Web technologies are exploited to foster science learning in an integrated but mobile smart learning environment. Contextawareness is considered a crucial skill in science learning, therefore we imagined a solution to train students for context awareness by illustrating context gaps based on on-site observations and measurements. A componen...

with the increase of the number of cameras installed across a video surveillance network, the ability of security staffs to attentively scan all the video feeds actually decreases. therefore, the need for an intelligent system that operates as a tracking system is vital for security personnel to do their jobs well. tracking people as they move through a camera network with non-overlapping field...

the purpose of this study was to examine how four teachers used the seven processes of videotape analysis to develop an analytic approach and reflective thinking towards their teaching. the study was organized within video clubs and was used to describe the interactions among four teachers about their experiences at a language institute. data were gathered through videotaped recordings of lesso...

One the most cited papers in astronomy is Ken Freeman's 1970 paper on exponential disks in galaxies. In this contribution I review what has been done in this area since then and what we can infer about systematic properties of disks in galaxies from surface photometry, HI synthesis observations and measurements of stellar kinematics. Most disks have radial truncations at 3.6 ± 0.6 radial scalel...
