At present, a single viable population of endangered African wild dogs occurs in South Africa, in the Kruger National Park. Current conservation efforts focus on reintroducing wild dogs into a series of fenced reserves, thereby creating a meta-population in which sub-populations are actively managed to conserve genetic diversity. Additional options exist for conserving wild dogs outside protect...

Feline immunodeficiency virus is a lentivirus of domestic cats that causes significant lifelong infection. Infection with this or similar lentiviruses has been detected in several nondomestic feline species, including African lions (Panthera leo). Although lion lentivirus (FIVple) infection is endemic in certain lion populations in eastern and southern Africa, little is known about its pathogen...

This paper presents a vision-based color segmentation algorithm suitable for urban environments that separates an image into areas of drivable and non-drivable terrain. Assuming that a part of the image is known to be drivable terrain, other parts of the image are classified by comparing the Euclidean distance of each pixel’s color to the mean colors of the drivable area in real-time. Moving th...

This paper describes a data set collected by MIT’s autonomous vehicle Talos during the 2007 DARPA Urban Challenge. Data from a high precision navigation system, 5 cameras, 12 SICK planar laser range scanners, and a Velodyne high density laser range scanner were synchronized and logged to disk for 90km of travel. In addition to documenting a number of large loop closures useful for developing ma...

[1] The San Andreas Fault (SAF) is the transform boundary between the Pacific and the North American plates, yet up to 25% of the relative plate motion is now accommodated by the eastern California shear zone (ECSZ). Here we investigate the inception of the ECSZ and its geodynamic interactions with the SAF using a 3‐D viscoelastoplastic finite element model. For a given fault configuration of t...

We present an approach that allows mission and contingency management to be achieved in a distributed and dynamic manner without any central control over multiple software modules. This approach comprises two key elements—a mission management subsystem and a Canonical Software Architecture (CSA) for a planning subsystem. The mission management subsystem works in conjunction with the planning su...

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...
