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 ...

The period around millennium-change has seen the boom of different e-commerce solutions and initiatives. First dedicated new economy companies (the so-called dotcom-companies) seemed to rob the market, but little by little established oldeconomy companies have taken a more dominating role in the market. This study follows the early months of development of the interactive reservation system for...

Background: Entrepreneurship plays an important role in the development of any country. Entrepreneurship is seen as the driving force behind economic development and the identification of opportunities and the use of resources, and entrepreneurs are those who, by recognizing opportunities, ensure success in manufacturing, business, and services. However, it should be noted that the criterion fo...

The advancements in computing have resulted in a boom of cheap, ubiquitous, connected mobile devices as well as seemingly unlimited, utility style, pay as one go computing resources, commonly referred to as cloud computing. It is desirable to have ubiquitous access to emails and information through mobile computing. More and more individuals are carrying smartphones and utilizing tablet PCs for...

Abstract This paper introduces a supersonic transport aircraft design model developed in the GENUS conceptual environment. A appropriate to transports with low-to-medium-fidelity methods are GENUS. With this model, authors reveal relationship between sonic boom signature and lift volume distributions possibility optimise distribution together so that they can cancel each other at some region. n...

Engineering fatigue fracture failure is one of the most common phenomena of mechanical and structural failure, statistically representing approximately 50 to 90% of total mechanical damage [1]. Lattice structures have been widely used in crane booms, steel plants, parking garages, offshore platforms and other fields [2] to [4]. In a crane, the lattice boom has better mechanical properties compa...

This paper considers a lightweight boom with an integral hinge consisting of a thinwalled tube made of carbon fibre reinforced plastic with two longitudinal slots. The dynamic deployment of this boom is studied both experimentally and by means of detailed finite-element simulations. The deployment of the boom can be divided into three phases: deployment; incomplete latching, buckling of the tap...
