The airport provides various facilities to meet the day to day needs of the passengers. They carry passengers from different locations to their desired locations with the help of various features adopted inside the airport. But in case of physically challenged person, who finds it difficult to locate without help in a airport, external guiding assistance like special robots or people to visually guide them are provided. In order to avoid the extra expenses a new passenger path tracking and management (PTM) system is established. This system provides a feature of multiuser language module handset through which the passengers are easily guided and navigated to places like boarding point, food court, toilet, cargo section etc. In this paper, we developed a new algorithm for tracking the destination for communicating the handset to other nodes. Simulation results proved that the proposed scheme performs efficiently. © 2013 IEEE.

In the title compound, C18H19BrN2O 4, the chromene unit is not quite planar (r.m.s. deviation = 0.199Å), with the methyl C atoms lying 0.027(4) and 1.929(4)Å from the mean plane of the chromene unit. The six-membered carbocyclic ring of the chromene moiety adopts an envelope conformation, with the dimethyl-substituted C atom as the flap. The methylamine and nitro groups are slightly twisted from the chromene moiety, with C - N - C - O and O - N - C - C torsion angles of 2.7(4) and -0.4(4)°, respectively. The dihedral angle between the mean plane of the chromene unit and the benzene ring is 85.61(13)°. An intramolecular N - H⋯O hydrogen bond generates an S(6) ring motif, which stabilizes the molecular conformation. In the crystal, molecules are linked via N - H⋯O hydrogen bonds, forming hexagonal rings lying parallel to the ab plane. A region of disordered electron density, most probably disordered ethanol solvent molecules, occupying voids of ca 432Å3 for an electron count of 158, was treated using the SQUEEZE routine in PLATON [Spek (2009). Acta Cryst. D65, 148-155]. Their formula mass and unit-cell characteristics were not taken into account during refinement. © 2014 CrossMark.

In the title compound, C31H25N5O3·C2H6OS, the three indole/indoline units are all essentially planar with maximum deviations of 0.0172 (3), 0.053 (2) and 0.07 (2) Å. The pyrrolidine ring adopts an envelope conformation with the C atoms bearing the 1-ethyl-2-oxoindole substituent (in which the five-membered ring adopts a twisted conformation) as the flap. The dimethyl sulfoxide solvent molecule is disordered over two positions, with an occupancy factor ratio of 0.871 (4):0.129 (4). The solvent components are linked to the heterocyclic molecule via C - H⋯O and C - H⋯S hydrogen bonds. In the crystal, the solvent components are linked to the heterocyclic molecule via C - H⋯O and C - H⋯S interactions, forming R2 2(10) ring motifs. The molecules are further connected into a chain along the a-axis direction via N - H⋯O hydrogen bonds.

Security is becoming an everyday concern for a wide range of embedded systems that manipulate, communicate, and store sensitive data. In today’s technology, wide range of applications have to be incorporated with in a single resource limited embedded system. These applications practices varying range of reliability, security and performance requirements. This project aims at developing new security architecture for embedded system using a reconfigurable hardware. This new hardware approach makes use of the capabilities of reconfigurable hardware to provide efficient and flexible architectural support for security standards, performance issues and defenses against a range of hardware attacks. This security architecture is based on three main ideas: 1. Reconfigurable security primitives, 2. Reconfigurable hardware monitors, 3. A hierarchy of security controllers at the primitive, system and executive level. © Research India Publications.

In the title compound, C19H22N2O5, the six-membered carbocyclic ring of the chromene moiety adopts an envelope conformation with the dimethyl-substituted C atom as the flap. The pyran ring has a flat-boat conformation. The meth-oxy-phenyl ring is orthogonal to the mean plane of the chromene moiety, with a dihedral angle of 89.97(8). The amine N atom deviates from the chromene mean plane by 0.1897(16). The methyl-amine and the nitro group are involved in an intra-molecular N-HO hydrogen bond which generates an S(6) ring motif. They are slightly twisted out of the plane of the chromene moiety with torsion angles of C-N-C-O(pyran) = 2.2(3) and O(nitro)-N-C-C = -5.6(2). In the crystal, there are only C-H inter-actions present, forming inversion-related dimers.

Clutch plates are usually made of cast iron and high carbon steels. The properties of cast iron have high compressive strength, low tensile strength and no ductility. Due to this reason, it is suitable for the clutch plate but its cost is high. In order to reduce the cost of clutch plate material without affecting the life and effectiveness of the clutch plate, we modify other material for clutch plate. Hence, we selected the clutch plate from MF241DI tractor. The material which is used in this pressure plate is grey cast iron (FG300). We analyzed this material to obtain the stress in the pressure plate. After obtaining the values, we use different materials but with suitable properties to obtain a better stress and functions of pressure plate. Hence, we use steel (30Cr13) and steel En15 as optional material to grey cast iron. These materials also have similar properties of grey cast iron. Then, we compare the stress values of all materials and take out the best. © 2013 IEEE.

In the title compound, C26H20N4O2S, the central pyrrolidine ring adopts a twist conformation on the C-C bond involving the spiro C atom. Its mean plane makes dihedral angles of 78.83(14), 65.91(15) and 44.49(18) with the mean planes of the adjacent oxindole ring system, the indole system and the thio-phene ring, respectively. The indole and indoline units are essentially planar, with maximum deviations of 0.019(3) and 0.090(3), respectively. In the oxindole fused-ring system, the pyrrole ring adopts an envelope conformation with the spiro C atom as the flap. In the crystal, pairs of N-HO hydrogen bonds link the mol-ecules, forming inversion dimers with an R (2) 2(8) ring motif. The dimers are linked by further N-HO hydrogen bonds, forming a two-dimensional network lying parallel to (100).
