Internal and External Factors Impacting Construction Labour Productivity for Glazing of Doors and Windows
Abstract: The efficiency of glazing installation during building construction is impacted by internal and external factors, which affect labour productivity. External factors are exogenous to the construction sites but have an overarching influence on the productivity of site operations, while internal factors emanate from the construction firms and their site operations. This study examines the internal and external factors impacting construction labour productivity for the glazing of doors and windows, using …

Schmitt-Trigger Based 12T SRAM Cell with Enhanced Stability
Abstract: In this work, we present a single-ended Schmitt-trigger (ST) based 12T static random access memory (SRAM) cell. The proposed cell employs cross-point data aware write structure, and thus supports bit interleaving architecture to mitigate soft errors. The proposed cell does not suffer from read disturbance as bit line is completely isolated from bit storage node. Simulation is done on 180 nm CMOS technology on Cadence. Read static noise margin (RSNM) …
