The carbon emissions of sectors and households enabled by primary inputs have practical significance in reality. Considering the mutual effect between industrial sector household, this paper firstly constructed an environmentally extended semi-closed Ghosh input–output model with endogenized household to analyze relationship Chinese economy from supply-side perspective. structural decomposition...

Weakly stationary time series are defined by a slow decay of autocorrelations and a pole of the spectral density at the origin. Sample paths tend to exhibit local spurious trends and cycles of varying length and magnitude. Visual separation of stationary long-memory components and deterministic trend functions is difficult. Statistical methods such as kernel and local polynomial smoothing and w...

Accompanying myriad definitions of critical literacy is an absence of pedagogical models for implementing critical literacy in teacher education contexts. This action research explores critical literacy with pre-service and in-service teachers in teacher education courses offered in the United States. The primary data sources include online weekly discussions on course readings in the TESOL met...

supply chain management is one of modern approach in the field of operation and production management. nowadays success and survival of manufacturing organizations depend on effectiveness and productivity of supply chains. this research tries to investigate contributing factor to enhance supply chain productivity. then by using fuzzy promethe-a multiple attribute decision making (madm) - tous a...

nt matter & 2007 IAgrE. emseng.2007.11.011 hor. : fabrizio.dabbene@polito The design of the supply chain, and in particular of the distribution phase, for fresh-food products, such as fresh and fresh-cut produce, fruit or meat, cannot be achieved without considering the perishable nature and the variability of the products entering the chain. Motivated by these considerations, this paper presen...

Hurricanes Katrina and Rita caused severe economic disruptions without warning in Louisiana and surrounding areas. These natural disasters temporarily created production losses in the oil-industry and lead to further economic losses via inter-industry linkages. Because oil is a key resource in the national economy, estimation of the economic impacts of these disasters can be accomplished with a...

Torque control strategy is a common strategy to control robotic manipulators. However, it becomes complex duo to manipulator dynamics. In addition, position control of Permanent Magnet Synchronous Motors (PMSMs) is a complicated control. Therefore, tracking control of robots driven by PMSMs is a challenging problem. This article presents a novel tracking control of electrically driven robots wh...
