The challenge of mobile adhoc network (MANET) is to keep the path active for long time. Since the path breaks due to node movement and limited battery power. The route is repaired and discovered only after a path breaks in existing routing protocols. Detection of route break and establishment of a new route insisted a high cost on the network. Preemptive route repair can be an alternative. It a...

Previous studies on inferring the origin of routing changes in the Internet are limited to failure events that generate a large number of routing changes. In this paper, we present a novel approach to origin inference of small failure events. Our scheme focuses on routing changes imposed on preferred paths of prefixes and not on transient paths triggered by path exploration. We first infer the ...

Abstract. Most navigation systems for pedestrians output the shortest route. However, there are findings that travellers do not use route when free to choose. One alternative minimising spatial distance is incorporation of landmark information in a algorithm. Yet, we know whether prefer such over Therefore, perform survey and show participants videos We let answer questions concerning satisfact...

In a route search over geospatial data, a user provides terms for specifying types of geographical entities that she wishes to visit. The goal is to find a route that (1) starts at a given location, (2) ends at a given location, and (3) travels via geospatial entities that are relevant to the provided search terms. Earlier work studied the problem of finding a route that is effective in the sen...

Enzymes involved in the last 2 steps of nicotinamide adenine dinucleotide (NAD) cofactor biosynthesis, which catalyze the adenylylation of the nicotinic acid mononucleotide (NaMN) precursor to nicotinic acid dinucleotide (NaAD) followed by its amidation to NAD, constitute promising drug targets for the development of new antibiotics. These enzymes, NaMN adenylyltransferase (gene nadD) and NAD s...
