Spinning Test Particle in Kalb-Ramond background
In this work we explore the geodesic deviations of spinning test particles in
a string inspired Einstein-Kalb Ramond background. Such a background is known
to be equivalent to a spacetime geometry with torsion. We have shown here that
the antisymmetric Kalb-Ramond field has significant effect on the geodesic
deviation of a spinning test particle. A search for an observational evidence
of such an effect in astrophysical experiments may lead to a better
undestanding of the geometry of the background spacetime.Comment: 14 pages, Latex, 5 figure
Timed Automata Approach for Motion Planning Using Metric Interval Temporal Logic
In this paper, we consider the robot motion (or task) planning problem under
some given time bounded high level specifications. We use metric interval
temporal logic (MITL), a member of the temporal logic family, to represent the
task specification and then we provide a constructive way to generate a timed
automaton and methods to look for accepting runs on the automaton to find a
feasible motion (or path) sequence for the robot to complete the task.Comment: Full Version for ECC 201
Importance of Municipal Solid Waste Management
Solid waste management is one among the fundamental and essential services provided by municipal authorities in the developed as well as developing countries to keep urban areas clean. In certain regions of our country, the free disposal facilities have reached their own capacity and even local governments are confronted with difficult decisions. Solid waste management is an integral element of modern society. There are many ways in which solid waste can be treated, and thanks to modernized practices and technological advancement, these methods are very safe and practical
Stomatal parameters in nine species of Corchorus (Tiliaceae)
Stomatal parameters namely stomatal size variation including aperture size (area), frequency of distribution, and conductance were studied in nine species (cultivated- C. capsularis L.- JRC 321, C. olitorius L. – JRO 524; wild - C. aestuans L. – WCIJ 088, C. fascicularis Lam. – WCIJ 150, C. pseudocapsularis L.- CIM 036, C. pseudoolitorius I. and Z. – OIN 507, C. tridens L.- WCIJ 149, C. trilocularis L.- KBA 222 and C. urticaefolius W. and A.- WCIJ 070- the species were grown under uniform agro-climatic condition) of Jute in an attempt to screen drought tolerant species and genotypes demonstrating enhanced photosynthetic efficiency. Stomata of jute species are paracytic, amphistomatic and anisostomatic. Results indicated that C. aestuans, C. urticaefolius, C. trilocularis and C. pseudoolitorius were drought tolerant; while C. pseudoolitorius and C. fascicularis were apparently with enhanced photosynthetic efficiency. The desirable traits in wild germplasm may be used for efficient breeding and crop improvement.Keywords: Jute species, drought tolerance, photosynthetic efficiency, efficient breedin
