We describe a new, simplified, and general analysis of a fusion of Nesterov’s accelerated gradient with parallel coordinate descent. The resulting algorithm, which we call BOOM, for boosting with momentum, enjoys the merits of both techniques. Namely, BOOM retains the momentum and convergence properties of the accelerated gradient method while taking into account the curvature of the objective ...

Is the stock market boom a result of the baby boom? This paper develops an overlapping generations model in which a baby boom is modeled as a high realization of a random birth rate, and the price of capital is determined endogenously by a convex cost of adjustment. A baby boom increases national saving and investment and thus causes an increase in the price of capital. The price of capital is ...

INTRODUCTION Boom and bust or overshoot and collapse dynamics are common among firms in a large range of different industries. bicycles, semiconductors and running shoes, are examples of industries where boom and bust (Meadows, 1970) as well as industries with pronounced product and/or category lifecycles (Klepper, 1996). 2 The common managerial behavior underpinning boom and bust dynamics (B&B...

Loads subjected by the boom system on the concrete pump are so complex, that fatigue cracks or fatigue fractures appear, which may lead to loss of property and casualty. However, when the concrete pump is functioning in safe condition, the damage of the boom system is reduced, thereby preventing the accidents. In order to select safe working conditions, a boom system of 37m concrete pump as res...

The Arab world is experiencing an economic boom of historic proportions. The tiny Persian Gulf emirate of Dubai is emblematic. Boasting the world’s only 7-star hotel, its massive land reclamation project, allegedly the only manmade structure visible from the moon, is whimsically creating parcels shaped like continents and palm trees. With oil hovering around $90 a barrel and the Egyptian stock ...

PROBLEM Incident investigation reports do not usually contain enough information to aid in studying boom arm vertical speed for roof bolting machines to determine the impact that appendage speed had on an operator's risk of experiencing a contact. Laboratory experiments with human subjects are also not feasible because of safety and ethical issues. METHOD Researchers successfully developed a ...

Decreasing supplies of high quality crude oil and increasing demand for high quality distillates have motivated the interest in converting natural gas to liquid fuels, especially with the present boom in natural gas proven reserves. Nevertheless, one major issue is the curtailment of costs incurred in producing synthesis gas from natural gas, which account for approximately 60% of the costs use...
