Indoor Navigation Algorithm For Mobile Robot

Recently there has been increasing research on the development of localization and navigation systems. Whereas most of the proposed approaches are suitable for outdoor operation, only a few techniques have been designed for indoor environments. This paper details the development of an indoor navigation system. It presents a general system consisting of sensors and algorithms for localization and navigation which enables to operate indoors. This is done by using trilateration method which has been successfully applied on complex nature of indoor environments. Set of experiments presented to validate our system using MATLAB program. Testing verified that good accuracy, sufficient for navigation, was achieved. This technique shows promise for future handheld indoor navigation systems that can be used in malls, museums, hospitals, and college campuses

A nonlinear hydrodynamical approach to granular materials

We propose a nonlinear hydrodynamical model of granular materials. We show how this model describes the formation of a sand pile from a homogeneous distribution of material under gravity, and then discuss a simulation of a rotating sandpile which shows, in qualitative agreement with experiment, a static and dynamic angle of repose.Comment: 17 pages, 14 figures, RevTeX4; minor changes to wording and some additional discussion.

The intensity of malaria transmisson and efficacy of Alphacypermethrin as an indoor residual insecticide against malaria vectors in Kadawa, Kano

Malaria is currently affecting more people in the World than any other disease and no single measure of control through the use of drugs seems effective. Malaria is said to kill one African (Whether child or adult every 15 second) and roughly 300,000 Nigerian children annually. A crossectional study was carried out to assess the impact of alphacy phermethrin as an indoor residual insecticide against malaria vectors and transmission in Kadawa irrigation area, Kano. A total of 1897 mosquitoes were collected indoors using WHO standard techniques in the selected areas between December 2010 and June 2011. Specimens were identified using morphological keys and PCR-based assays. ELISA tests were used to detect P. falciparum sporozoite infection. Of the 1897 Anopheles mosquitoes collected, An. funestus group, the predominant vector species, represented 63.6% while An. gambiae s.l. has 18.5% while other anopheles and culicines 17.9%. The control group (Alphacyphermethrin treated group) catch 1332 (85.6%) predominated over the intervention group (Non-alpha cyphernethrin treated group) 224 (14.4%) with an extreme significant difference (P < 0.0001). The result of PCR based test identified 22% of the mosquitoes of the Anopheles gambiae complex collected as An. gambiae s.s., 96% and An. arabiensis as 4%.The overall sporozoite rates for An. funsetus and An. gambiae s.s. were statistically significant in both groups. Infection rates in both intervention and control group were also statistically significant. The result of the study showed that, the indoor residual spray of alphacyphermethrin has seen to have assisted in reduction of malaria transmission and malaria vectors in the study area from 15.9% in control group to 4.1% in intervention group and 78.8% in control group to 21.2% in intervention group respectively. Key words: Malaria; Alpha cyphermethrin; ELISA ; PCR

CMS physics technical design report: Addendum on high density QCD with heavy ions

This report presents the capabilities of the CMS experiment to explore the rich heavy-ion physics programme offered by the CERN Large Hadron Collider (LHC). The collisions of lead nuclei at energies ,will probe quark and gluon matter at unprecedented values of energy density. The prime goal of this research is to study the fundamental theory of the strong interaction - Quantum Chromodynamics (QCD) - in extreme conditions of temperature, density and parton momentum fraction (low-x). This report covers in detail the potential of CMS to carry out a series of representative Pb-Pb measurements. These include "bulk" observables, (charged hadron multiplicity, low pT inclusive hadron identified spectra and elliptic flow) which provide information on the collective properties of the system, as well as perturbative probes such as quarkonia, heavy-quarks, jets and high pT hadrons which yield "tomographic" information of the hottest and densest phases of the reaction.0info:eu-repo/semantics/publishe
