Traditional synchronization schemes of multimedia applications are based on temporal relationships between inter- and intrastreams. These schemes do not provide good synchronization in the presence of random delay. As a solution, this paper proposes an adaptive content-based synchronization scheme that synchronizes multimedia streams by accounting for content in addition to time. This approach to synchronization is based on the fact that having two streams sampled close in time does not always imply that these streams are close in content. The proposed scheme primary contribution is the synchronization of audio and video streams based on content. The secondary contribution is adapting the frame rate based on content decisions. Testing adaptive content-based and adaptive time-based synchronization algorithms remotely between the American University of Beirut and Michigan State University showed that the proposed method outperforms the traditional synchronization method. Objective and subjective assessment of the received video and audio quality demonstrated that the content-based scheme provides better synchronization and overall quality of multimedia streams. Although demonstrated using a video conference application, the method can be applied to any multimedia streams including nontraditional ones referred to as supermedia like control signals, haptic, and other sensory measurements. In addition, the method can be applied to synchronize more than two streams simultaneously.

The most frequently asked questions regarding the phenomenon of American universities in the Arabian Gulf are: how good are they and how likely are they to endure? Already one of the first to enter the arena (George Mason University in 2005) was forced to close its Ras al-Khaimah campus in October of 2009 “after reaching an impasse with our partner over budget and control issues” (http://eagle.gmu.edu/newsrooms/740). GMU’s former students were directed to its American campus and seven other institutions within the UAE with whom GMU had teach-out agreements. One of these seven institutions has now closed as well: on 6 July 2010 Michigan State University (MSU) announced it was closing its undergraduate programs in Dubai. Its former students were offered a special package to attend the MSU campus in Lansing. As reported in the Lansing State Journal, the reason given was that the Dubai campus had “failed to attract sufficient numbers of students and was no longer financially sustainable.” It had just eighty-five students. However, MSU still had to pay between $1.3–1.7 million in “wind-down costs” (http://lansingstatejournal.com/article/20100706/NEWS01/307060031/MSU-to-close-programs-at-Dubai-campus).

Omar Nashabe, an instructor of human rights at the Lebanese American University (LAU) and an instructor of Sociology at the American University of Beirut (AUB) and Haigazian University, is currently working on a voluntary basis, to improve the situation of human rights in Lebanese prisons. Nashabe earned his BA at the American University of Beirut and MA in Social Policy at the State University of New York (SUNY), and it is in those university years that he got interested in crime, deviance and rehabilitation.

Bovine respiratory diseases cause serious economic loses and present diagnostic difficulties due to the variety of etiologic agents, predisposing conditions, parasites, viruses, bacteria and mycoplasma, and may be multiple or complicated. Several agents which have been isolated from the abnormal lungs are still the subject of controversy and uncertainty. These include adenoviruses, rhinoviruses, syncytial viruses, herpesviruses, picornaviruses, mycoplasma, chlamydiae and Haemophilus somnus.Previously, we have studied four typical cases of bovine pneumonia obtained from the Michigan State University Veterinary Diagnostic Laboratory to elucidate this complex syndrome by electron microscopy. More recently, additional cases examined reveal electron opaque immune deposits which were demonstrable on the alveolar capillary walls, laminae of alveolar capillaries, subenthothelium and interstitium in four out of 10 cases. In other tissue collected, unlike other previous studies, bacterial organisms have been found in association with acute suppurative bronchopneumonia.

The development of a scanning electron microscope (SEM) suitable for instructional purposes has created a large number of outreach opportunities for the Materials Science and Engineering (MSE) Department at Iowa State University. Several collaborative efforts are presently underway with local schools and the Department of Curriculum and Instruction (C&I) at ISU to bring SEM technology into the classroom in a near live-time, interactive manner. The SEM laboratory is shown in Figure 1.Interactions between the laboratory and the classroom use inexpensive digital cameras and shareware called CU-SeeMe, Figure 2. Developed by Cornell University and available over the internet, CUSeeMe provides inexpensive video conferencing capabilities. The software allows video and audio signals from Quikcam™ cameras to be sent and received between computers. A reflector site has been established in the MSE department that allows eight different computers to be interconnected simultaneously. This arrangement allows us to demonstrate SEM principles in the classroom. An Apple Macintosh has been configured to allow the SEM image to be seen using CU-SeeMe.
