In this paper with the help of different empirical models we have estimated the value of monthly average global solar irradiation for Ranchi (23.3500 ̊N, 85.3300 ̊E), a tropical location. The values of monthly average global solar radiation are calculated using the regression constants in the models (both linear and quadratic) suggested by: AngstromPrescott, Rietveld, Ogleman, Akinoglu, Glover, G...

Ficus microcarpa is an Asian fig tree that is ornamentally cultivated. The specific pollinator, Eupristina verticillata Waterston, and the non-pollinators Walkerella microcarpae Boucek and Philotrypesis emeryi Grandi, have been reported associated to F. microcarpa in Brazil. In here we report for the first time the occurrence of Odontofroggatia ishii Wiebes and Philotrypesis taiwanensis Chen et...

[1] We determine a regional spatiotemporal gravity field over northern South America including the Amazon region using GRACE inter-satellite range-rate measurements by application of a wavelet-based multiresolution technique. A major advantage of this method is that we are able to represent the Amazon hydrological signals in form of time series of detail signals with level-dependent temporal re...

This article provides a survey on modern methods of regional gravity field modeling on the sphere. Starting with the classical theory of spherical harmonics,weoutline the transition towards space-localizing methods such as spherical splines and wavelets. Special emphasis is given to the relations among these methods, which all involve radial base functions. Moreover, we provide extensive applic...

The concepts studied during Offset Stream Technology (OST) test were all designed to produce directional jet noise reduction in a separate flow engine configuration by redirecting the fan stream relative to the core stream, creating a thicker fan flow on one side of the jet. Previous studies, conducted at bypass ratios of five or less showed that lower noise levels would result on the thickened...

In aquatic vertebrates such as the cyclostomes, fishes, and urodele Amphibia, the digestive tract develops as a relatively straight tube characteristicalaly bent toward the right side in the region of the pylorus and duodenum. Aiiuran amphibians excite particular interest because they are the most primitive vertebrate group to deve1,op a highly coiled intestine, such as amniotes generally posse...

The 2007 Darpa grand challenge is a 100 km race between autonomous vehicles in an urban environment. This paper presents the results of kinematic motion study in order to quantify the minimum perception range requirements of a canonical set of manoeuvres that are required for the event. The paper also considers the potential advantage that a course reversal strategy may provide competitors that...

This paper reports on various aspects of the Intelligent Vehicle Systems (IVS) team’s involvement in the recent 2007 DARPA Urban Challenge, wherein our platform, the autonomous “XAV-250,” competed as one of the 11 finalists qualifying for the event. We provide a candid discussion of the hardware and software design process that led to our team’s entry, along with lessons learned at this event a...
