The change in orbit evolution between collocated satellites (X, Y) inside +/-0.09° E/W and +/0.07° N/S cluster, after one of these satellites is placed in an inclined orbit (satellite X) and the effect of this change in the collocation safety inside the cluster window has been studied and evaluated. Several collocation scenarios had been studied in order to adjust the location of both satellite...

Multimodal optimization aims at finding multiple global and local optima (as opposed to a single solution) of a function, so that the user can have a better knowledge about different optimal solutions in the search space and as and when needed, the current solution may be switched to another suitable one while still maintaining the optimal system performance. Evolutionary Algorithms (EAs) due t...

Traditional medicine in Bhutan is known as gSo-ba Rig-pa and is one of the oldest surviving medical traditions in the world. Other medical systems, such as Chinese medicine, Indian Ayurvedic medicine, Unani medicine, Greco-Roman medicine and the country's rich cultures and traditions have greatly influenced the way traditional Bhutanese medicine evolved. However, Buddhist philosophy remains the...

In order to keep the flux constant when asynchronous motor is running under load, especially light a Glowworm swarm optimization (GSO) algorithm proposed control voltage frequency ratio of cycloconverter. Based on analysis two variable theory cycloconverter and working principle cycloconverter, self-control method by adaptive fuzzy backstepping sliding mode proposed. process, GSO BFA are integr...

Computation of superstring partition functions for the non-linear sigma model on the product of a two-torus and its dual within the scope of the doubled formalism is presented. We verify that it reproduces the partition functions of the toroidally compactified type–IIA and type–IIB theories for appropriate choices of the GSO projection.

We report Suzaku observations of the active, Compton-thick Circinus galaxy. Observations were obtained with both the X-ray Imaging spectrometer (XIS) and the Hard X-ray Detector (HXD). Below 10 keV, the nuclear spectrum is dominated by radiation reflected from cold dense gas of high column density, while above 13 keV the radiation is directly transmitted nuclear emission seen through a column d...

In this paper we address the problem of multiple odor source localization using mobile robot swarms modelled as network robot systems. These networked robots are used to locate multiple radiation/odor sources like oil spills, leaks in pressurized systems, hazardous plumes/aerosols resulting from nuclear/chemical spills, deepsea hydrothermal vent plumes, fire-origins in forest fires, and hazardo...

We extend a recent calculation of the nuclear energy density functional in the systematic framework of chiral perturbation theory by computing the isovector spin-orbit terms: (~ ∇ρp− ~ ∇ρn) · ( ~ Jp− ~ Jn)Gso(kf )+ ( ~ Jp− ~ Jn) GJ(kf ). The calculation includes the one-pion exchange Fock diagram and the iterated one-pion exchange Hartree and Fock diagrams. From these few leading order contribu...
