Orthodontics, authors’ opinions and scientific facts:Cum hoc ergo propter hoc?

Cum hoc ergo propter hoc ("With this, therefore because of this").

Money may matter , but how could you know ?

Christina and David Romers’ reply to our article ‘Post Hoc Ergo Propter Hoc Once More’ misses the point. Our argument was never that monetary policy did not matter, but that their methods could not provide useful evidence that it did. Yet, they offer additional evidence of the same type with respect to the efficacy of monetary shocks without effectively replying to the criticisms of their metho...

Assessment of DSACC and QPART Algorithms in Ad Hoc Networks

The rapid advancement in wireless over wired has augmented the need for improving theQuality of Service (QoS) over such wireless links. However, the wireless ad hoc networkshave too low bandwidth, and establishing a QoS in these networks is a difficult issue. So,support of quality of service in ad hoc networks is the topical issue among the networkscience researchers. In this research we are go...

Improving Vehicular Ad-Hoc Network Stability Using Meta-Heuristic Algorithms

Vehicular ad-hoc network (VANET) is an important component of intelligent transportation systems, in which vehicles are equipped with on-board computing and communication devices which enable vehicle-to-vehicle communication. Consequently, with regard to larger communication due to the greater number of vehicles, stability of connectivity would be a challenging problem. Clustering technique as ...

Enabling Ad Hoc Queries over Low-Level Scientific Data Sets

Technological success has ushered in massive amounts of data for scientific analysis. To enable effective utilization of these data sets for all classes of users, supporting intuitive data access and manipulation interfaces is crucial. This paper describes an autonomous scientific workflow system that enables high-level, natural language based, queries over low-level data sets. Our technique in...
