Scatterometers are remote sensing radars designed to measure near-surface winds over the ocean. The difficulties of accommodating traditional fan-beam scatterometers on spacecraft has lead to the development of a scanning pencilbeam instrument known as SeaWinds. SeaWinds will be part of the Japanese Advanced Earth Observing Satellite II (ADEOSII) to be launched in 1999. To analyze the performan...

Differences in the Defense Mechanism Technique modified (DMTm), a percept-genetic tachistoscopic technique, between 56 patients with a main diagnosis of mild, moderate or severe unipolar depression and 42 with a main diagnosis of somatoform disorder were studied. As expected, the affect defenses of inhibition, introaggression and barrier isolation—all through their specified motive related to t...

SeaWinds is a spaceborne wind scatterometer to be flown on the second Japanese Advanced Earth Observing Satellite (ADEOS-II) in 1999. An important international element of NASA’s earth observing system (EOS), SeaWinds is an advanced follow-on to the NASA scatterometer (NSCAT) on the first ADEOS platform. Unlike previous operational spaceborne scatterometer systems, SeaWinds employs a scanning “...

Cognitive Radio Networks (CRNs) arise as a promising solution to the scarcity of spectrum. By means of cooperation and smart decisions influenced by previous knowledge, CRNs are able to detect and profit from the best spectrum opportunities without interfering primary licensed users. However, besides the well-known attacks to wireless networks, new attacks threat this type of networks. In this ...

Increasingly in the recent past, the focus on climate change is moving towards the understanding of the occurrence, both in magnitude and frequency, of extreme climatic events like droughts and floods. In this work, an effort has been made towards identification of spatial co-occurrence of droughts across various subdivisions of India, based on the historical climatological data of the past cen...

We consider the possibility that an infalling bulge core or stellar cluster could form an eccentric disk, following tidal disruption by a massive black hole in the center of a galaxy. As a function of central black hole mass, we constrain the core radii and central densities of cluster progenitors capable of becoming nearly Keplerian disks which can support lopsided slow modes. We find that pro...

Network denial-ofservice attacks, which exhaust the server resources, have become a serious security threat to the Internet. Public Key Infrastructure (PU) has long been introduced in various authentication protocols to verifL the identities of the communicating parties. Although the use of PKI can present dijjculty to the denial-of service attackers, the underlying problem has not been resolve...
