In this paper, we investigate scheduling algorithms that are suitable for ATM networks. In ATM networks, atl packets have a fixed small length of 53 bytes and they are transmitted at very high rate. Therefore a time complexity of a scheduling algorithm is quite important. Most scheduling algorithms proposed so far have a complexity of O (log iV) per packet,(More)
Virtual machine (VM) live migration, which is the ability to move a VM from one physical host to another under hypervisor control without suspending for a long time, is a capability being increasingly utilized. With IP mobility, a capability for migrating VMs among distributed sites is provided. We call it the global live migration. However, it affects an(More)
Today's wireless access networks consist of several overlapping tiers. Provision of real time undisrupted communication to mobile users, anywhere and anytime through these heterogeneous overlay networks, is a challenging task. This paper presents a handoff technique for mobile devices equipped with dual mode interfaces. The proposed mobile-controlled(More)
In videoconferencing, which means a small group meeting, interactive distance learning and so on, there is a requirement to get required video at remote site freely and easily by local control of a remote camera. However, there is some delays between camera control operations at a remote site and actual video images displayed on a local screen. Delays are(More)
The inferior pharyngeal constrictor muscle (IPC), which consists of the thyropharyngeal (TP) and cricopharyngeal (CP) muscles. plays an important role during deglutition. The histochemical properties of the canine IPC muscle were investigated. The motor endplates of the TP muscle clustered at the midlength of the muscle, while those of the CP muscle were(More)
Fifteen patients suffering from visual disturbance of varying degrees caused by a mucocele of the posterior ethmoid and/or sphenoid sinuses underwent marsupialization of a mucocele into the nasal cavity. Five of the eight patients with severe visual loss worse than 20/200 showed recovery of measurable vision. Two of these five were operated on within 24(More)
Neuromuscular junctions in the posterior cricoarytenoid (PCA) muscle of the adult rat larynx were examined by scanning electron microscopy. Two types of focal junctions were characterized by the nerve endings with terminal varicosities or terminal buttons and by the subneural apparatuses with a group of cup-like depressions (2-5 microns in diameter), not(More)
High speed computer networks will provide us with new broad band multimedia applications. This paper discusses new functions for the next generation VRML (Virtual Reality Modeling Language) over high speed computer networks. The LoD (Level of Detail) of 3D objects is the most important function for rendering scenes dynamically while managing the QoS(More)
With rapid spread of virtualization technologies, Live migration which provides the ability to migrate a running virtual machine (VM) among physical hosts without interruption. Especially, Global Live Migration (GLM) which enables to migrate VM across the geographically-distributed Wide Area Networks (WANs) is an essential step towards development of the(More)
The authors investigated the process of denervation and reinnervation of the interarytenoid (IA) muscle in the guinea pig using transmission electron microscopy and glycogen depletion technique after unilateral transection of the recurrent laryngeal nerve (RLN) and superior laryngeal nerve to clarify the innervation pattern of the unpaired IA muscle.(More)
