Computed tomography in a 3 1/2-year-old boy with ataxia, lethargy, fever, vomiting, and increasing irritability revealed moderate hydrocephalus and a blood density mass lesion lying superior and posterior to the 3rd ventricle. On several of the sections, the blood density was greater in the dependent than in the superior portion of the mass. The average… (More)
The authors report a patient with an epidermoid tumor that eroded through the frontal sinus, causing an acute neurological deficit secondary to tension pneumocephalus. The historical perspective, radiographic features, and pathophysiological mechanisms are discussed.
The increasing popularity of multimedia streaming applications introduces new challenges in content distribution networks. Streaming services such as video on demand (VoD) or digital television over the Internet (IPTV) are very bandwidth-intensive and cannot tolerate the high delays and poor loss properties of today's Internet. To solve these problems,… (More)
— The experienced quality of services such as IPTV, video on demand, online gaming and VoIP is very sensitive to packet loss, delay and jitter. Therefore it is an essential requirement that access network providers are able to monitor and control with rather high resolution the end-to-end service delivery paths. Because this task is very complicated we are… (More)
This paper describes a set-up for navigating into omnidirectional video using a tablet PC, onto which a backside camera is used for sensing the device orientation. This allows the system to automatically control the video navigation based on the device rotation, hence enabling an end-user to interact with the content in a very natural manner.
We present a system for 3D face reconstruction that is based on live depth information combined with face priors. The system includes a stereo matching method that employs prior information for limiting the search space and introduces an offline scanned 3D model that is animated by means of 2D morphing techniques in order to match the live facial… (More)
A male newborn with a large scalp and skull defect and a cervical meningocele was transferred to the neonatal intensive care unit of the North Carolina Baptist Hospital. The scalp defect measured 8.5 x 9.5 cm, and the sagittal sinus was exposed. Because the defect was considered too large to be covered with a rotation skin flap, it was treated thrice daily… (More)
A case report of cervical spinal cord compression by infolding of a silicone-coated Dacron graft is presented. The possible complications of synthetic dural substitutes are discussed.
