The role of mechanization and integration of manufacturing processes in achieving operational performance
No full textSmall manufacturing firms are the dominant organization type for most of the developed countries. However, these firms have not been the focus of research and their strategic and operational needs are not extensively addressed by the academic community. Therefore, this research aims at empirically finding the impact of mechanization and integration of manufacturing processes and systems on operational performance in small Danish manufacturing firms. We use data of 357 small Danish manufacturing firms and empirically found distinct impact of mechanization and integration of systems on operational performance in context of production to order (PTO) and production to stock (PTS) strategies
Geophysical and geotechnical characterization of Lower Sudhan Gali Landslide (LSGL), Bagh Azad Jammu & Kashmir
No full textThe evolution of the steep unstable slopes is influenced by landslides as a major geomorphological feature in the Kashmir region. The NW-SE–oriented landslide has affected the village of Birpani and the main Sudhan Gali Road. The Lower Sudhan Gali (LSG) landslide was studied using a combined use of ground-based remote sensing (Electrical Resistivity Tomography (ERT)) and space-borne remote sensing (Persistent Scatterer Interferometric Synthetic Aperture Radar (PSInSAR)) measurements, geotechnical and field surveys. PSInSAR data highlighted the parts of the landslide that are currently active as well as the immediate surrounding area experiencing uplift and subsidence phenomenon. ERT imaging has delineated the geometry and subsurface structural features of the LSGL. Geotechnical results indicated that the landslide material had a low to medium plasticity index, with a higher clay fraction that may have reduced its shear strength. Finally, the characteristics of this mass movement were observed during the geological field by analyzing the geomorphological features and the lithological units. The interplay among rainfall and close proximity of a major fault may have contributed to the landslide kinematics. The results provided important on- and near-ground surface information for effective planning interventions that can help with hazard mitigation
FEM Modeling of Squeeze Film Damping Effect in RF-MEMS Switches
Get PDFA very important aspect in the design of RF- MEMS switches, is to obtain low switching time. The switching time not only depends on the device geometric parameters but also on the operating conditions. This paper presents the squeeze film damping effect on the dynamic response of the RF-MEMS switches. The squeeze film damping effect, with and without perforations, on the switching time is analyzed using finite element method (FEM) simulations. The effect of temperature and humidity on the squeeze film damping and switching time is also investigated
