BACKGROUND Previous studies have shown that neurologic complications following carotid endarterectomy (CE) are underestimated if patients are not examined by neurologists after surgery. OBJECTIVE To review the morbidity and mortality in a cohort of patients examined before and after CE in a neurology and stroke clinic. METHODS This was a prospective(More)
The authors report eight pregnant women with acute ischemic stroke treated with thrombolysis (rt-PA [recombinant human tissue plasminogen activator] or urokinase). Seven women recovered. Two extracranial and two asymptomatic intracranial hemorrhages complicated treatment; one woman died of arterial dissection complicating angiography. Three patients had(More)
Many on a daily basis use time based alarms. Spatial alarms extend the very same idea to location-based triggers, which are fired whenever a mobile user enters the spatial region of the location alarms. Spatial alarms provide critical capabilities for many mobile location based applications ranging from personal assistants, inventory tracking to industrial(More)

The upflow anaerobic sludge blanket (UASB) process is known to be energy conservative biotechnology. Its low cost and low skill requirement render it to be a viable technology for reducing organic pollution loads. However, this system is facing a challenge in the treatment of low-strength wastewater especially inoculated with non-granular sludge. This work(More)
Naive B or B+ trees are very good and efficient for indexing single dimensional data but not well suited for multidimensional data. Antonin Guttman of University of California, Berkeley proposed a novel scheme for indexing multidimensional data called R Trees. Since then several variants of the R tree have been developed for for different situations and(More)
This paper proposes an adaptive spatio-temporal placement scheme for caching location dependent queries. The cache placement decision is made according to the potential cache benefit of the query results based on the spatio-temporal properties of query results and the movement patterns of the mobile client, aiming at increasing the cache hit ratio. We(More)
One of the major problems confronted by the hydrologists for many years is the prediction of runoff from a given basin for a known rainfall. In this situation, development of a rainfall runoff model is important in Veeranam tank catchment located at latitude 11° 15’00” and longitude 79° 30’00’ E in Cuddalore District of Tamilnadu, India. By considering the(More)
Caching in mobile systems is very important due to the fact that mobile devices are low on resources and bandwidth. Having a high cache hit rate would mean faster response, lesser messages to the server and hence lesser consumption of energy as well as lesser load on the server. Mobile cache replacement algorithms are different compared to web caching.(More)
