Simulation and Control of Rotational Vibration of Sprayer Boom Using a Novel Suspension System

Sprayers are important tools in agriculture that usually moved on the field by tractor. Sprayers should distribute the constant rate of chemicals during various conditions encountered in the field. Unwanted vibrations of sprayer boom cause redaction of its life time and over doses and under doses of chemical sprayed on the field. Therefore, in this study a model of suspension system for rotatio...

The Effect of Economic Boom & Recession on Environmental Pollution in Iran: Focusing on Economic Sectors

In this research, we attempt to investigate the effect of economic boom and recession on environmental pollution in Iran through an asymmetric approach. To this end, an autoregressive approach with nonlinear distributive pause was used with the data for the period (1971-2017) to explain and describe the asymmetry; Accordingly, a basic model (for the entire economy) and three partial patterns (f...

Dynamic Simulation of the Harvester Boom Cylinder

Based on the complete dynamic calculation method, the layout, force, and strength of harvester boom cylinders were designed and calculated. Closed simulations for the determination of the dynamic responses of the harvester boom during luffing motion considering the cylinder drive system and luffing angle position control have been realized. Using the ADAMS mechanical system dynamics analysis so...

Recent progress on sonic boom research at NASA

Sonic boom research conducted at NASA through the Supersonics Project of the Fundamental Aeronautics Program is oriented toward understanding the potential impact of sonic boom noise on communities from new low-boom supersonic aircraft designs. Encompassing research in atmospheric propagation, structural response, and human response, NASA research contributes to knowledge in key areas needed to...

Does the commodities boom support the export led growth hypothesis? Evidence from Latin American countries

Commodity prices are characterized by boom and bust cycles. In this article, the impact of the commodity boom of the 2000s on Latin American and Caribbean economies is studied by analyzing four categories of commodity exports (agricultural raw materials, fuel, food, ore and minerals) as well as manufactured exports. Latin American and Caribbean economies had higher growth during the 2000s than ...
