of sensory block was assessed by bilateral application of ice over the lower thorax and abdomen at 30 min post-procedure once the patient was alert and oriented in the recovery room. Bilateral assessments were done to rule out epidural spread. Sensory level of analgesia was recorded and patient satisfaction with analgesia documented. Ten patients (Table 1) underwent real-time lower TPVB for ana...

Petroleum refining and petrochemical industries start using infrared (IR) cameras to detect volatile organic compounds (VOC) leaking out of process equipment. However, further quantitative processing of these video image data or automatic recognition of VOC plumes are hindered by unaligned video frames owing to the slight vibrations of the camera. An automatic method is developed to align the I...

Use of mobile equipment has increased exponentially over the last decade. As use becomes more widespread so too does the demand for new functionalities. The limited memory and computational power of many mobile devices has proven to be a challenge resulting in many innovative solutions and a number of new standards. Despite this, there is often a requirement for additional enhancement to improv...

Applications of real-time video transmission in heterogeneous network and computing environments, like the Internet, need to be highly scalable and adaptive in terms of bandwidth and processing requirements. Layered video coding in combination with layered transmission schemes have been proposed as a solution to network and terminal equipment heterogeneity. In this paper we identify the fundame...

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...

drop size distribution in a mixer-settler is an essential design parameter, as obtaining drop size distribution will result in optimum performance of equipment. in this paper for obtaining drop size, several experiments have been performed with a single stage horizontal mixer-settler. a video technique has been used in order to measure the drop size in the mixer-settler with the help of a digit...

Laryngoscopy and rigid bronchoscopy represent a necessary tool in the otolaryngologist's arsenal. The advancement in designing smaller and more versatile laryngeal equipment and fiber-optic telescopes as well as the increasingly higher resolution of still and video imagery have allowed otolaryngologists to better diagnose and treat many airway lesions. This chapter describes the basic equipment...
