This research paper focuses on process improvement carried out in the nacelle unit of a wind turbine manufacturer. Lean Manufacturing (LM) is implemented to improve productivity in terms of manufacturing throughput time and to also reduce cost of rework/manufacturing costs. Tools like Root Cause Analysis and Kaizen were used in conjunction to create efficient results for the manufacturing processes. By assessing the current condition and establishing a baseline to work upon, improvement was achieved through the testing and implementation of solutions to the problems found. Process improvement was successful as seen in the acceleration of schedules and reduction in costs. © 2015 Elsevier Ltd.

The increasing number of Web service providers over the Web has prompted the need for research in service description and discovery. The Web service requesters need tools, in order to search suitable services that satisfy the requester's needs. The Web service discovery is defined as a mechanism that allows the service requester to gain an access to the service descriptions and make them available to the application at runtime for binding. The service requesters can retrieve a service descriptions at design time or at run time from the service description repository i.e. service registry like UDDI. The lookup mechanism must support a query mechanism to explore services based on the type of interface, the binding information (protocols), properties (QoS properties), the taxonomy of service and the business (provider) information etc. This paper reviews (and classifies) various architectures and matchmaking mechanisms defined in literature for the dynamic Web service discovery. © 2010 IEEE.

In this study, FT-IR, FT-Raman, NMR and UV spectra of 1-phenyl-1-propanol, an intermediate of anti-depressant drug fluoxetine, has been investigated. The theoretical vibrational frequencies and optimized geometric parameters have been calculated by using HF and density functional theory with the hybrid methods B3LYP, B3PW91 and 6-311+G(d,p)/6-311++G(d,p) basis sets. The theoretical vibrational frequencies have been found in good agreement with the corresponding experimental data. 1H and 13C NMR spectra were recorded and chemical shifts of the molecule were compared to TMS by using the Gauge-Independent Atomic Orbital (GIAO) method. A study on the electronic and optical properties, absorption wavelengths, excitation energy, dipole moment and frontier molecular orbital energies are performed using HF and DFT methods. The thermodynamic properties (heat capacity, entropy and enthalpy) at different temperatures are also calculated. NBO analysis is carried out to picture the charge transfer between the localized bonds and lone pairs. The local reactivity of the molecule has been studied using the Fukui function. NLO properties related to polarizability and hyperpolarizability are also discussed. © 2014 Elsevier B.V. All rights reserved.

Problem statement: In mobile ad hoc networks, frequent mobility during the transmission of data causes route failure which results in route rediscovery. In this, we propose multipath routing protocol for effective local route recovery in Mobile Ad hoc Networks (MANET). In this protocol, each source and destination pair establishes multiple paths in the single route discovery and they are cached in their route caches. Approach: The cached routes are sorted on the basis of their bandwidth availability. In case of route failure in the primary route, a recovery node which is an overhearing neighbor, detects it and establishes a local recovery path with maximum bandwidth from its route cache. Results: By simulation results, we show that the proposed approach improves network performance. Conclusion: The proposed route recovery management technique prevents the frequent collision and degradation in the network performance. © 2012 Science Publications.

The present paper focuses on preparation and process of the magnetorheological (MR) fluid whose carrier fluid is silicone-based oil and its additive is the commercial grease with different concentration of iron particles. General properties of MR fluid are discussed and rheological properties like shear rate, shear stress, viscosity of MR fluid can be found by using cone-and-plate sensor system-type rheometer. The result shows that shear stress as a function of magnetic flux density and viscosity does not strictly scale with iron loading. © 2014 World Scientific Publishing Company.
