T commercials are pervasive. Every time I hear the line, “I got a new scooter, and it didn’t cost me a dime,” I get an uneasy feeling, since the main message comes across as how to get “free stuff” from Medicare. It’s not surprising that some of the companies that provide scooters, oxygen, diabetes supplies, and various durable medical equipment (DME) have been investigated for fraud and abuse....

Virtually every piece of electronic equipment, e.g., computers and their peripherals, calculators, TV and hi-fi equipment, and instruments, is powered from a DC power source, be it a battery or a DC power supply. Most of this equipment requires not only DC voltage but voltage that is also well filtered and regulated. Since power supplies are so widely used in electronic equipment, these devices...

It is widely believed in the literature that inventory ‡uctuations are destabilizing to the economy. This paper re-assesses this view by developing an analyticallytractable general-equilibrium model of inventory dynamics based on a precautionary stockout-avoidance motive. The model’s predictions are broadly consistent with the U.S. business cycle and key features of inventory behavior, includin...

Theoretical models have been ambiguous on the relationship between industry competition and inventory holdings of manufacturing firms. Facing competition, on the one hand, firms may desire to hold more inventory to avoid losing sales to competitors; on the other hand, firms strive to improve inventory turns to control costs and stay competitive. Using U.S. Census data on manufacturing industrie...

In this work we deal with multilevel integrated distribution problems and in particular, we analyse the management of inventories of final goods in the distribution system. We present a survey of methods proposed in the recent literature devoted to the integration of inventory management systems. Starting from the concept of echelon inventory position we present an approach for the optimal flow...

In this research, solar-drived integrated Hydrogen production (HP) using high-temperature steam electrolysis (HTSE) is thermodynamically evaluated. This system includes an organic Rankine cycle (ORC), Rankine cycle, Brayton cycle, solar tower, and High Temperature Steam Electrolysis (HTSE). Solar energy supplies thermal energy. This heat source is applied for generating power. This energy is us...

OBJECTIVES This report presents data on the availability of pediatric services, expertise, and supplies for treating pediatric emergencies in U.S. hospitals. METHODS Data in this report are from the Emergency Pediatric Services and Equipment Supplement (EPSES), a self-administered questionnaire added to the 2006 National Hospital Ambulatory Medical Care Survey (NHAMCS). NHAMCS samples nonfede...
