This paper applies parametric and non-parametric and parametric tests to assess the efficiency of electricity distribution companies in Germany. We address traditional issues in electricity sector benchmarking, such as the role of scale effects and optimal utility size, as well as new evidence specific to the situation in Germany This paper applies parametric and non-parametric and parametric t...

Most embedded systems are small enough to sit on the end of your thumb and are usually hidden within much larger and more complex mobile computing or electronic devices, so they often go unnoticed. But embedded systems actually represent the vast majority of semiconductor sales. According to the World Semiconductor Trade Statistics blue book, there are an estimated 5 billion embedded microproce...

High rates of vitamin D deficiency and testing have been reported in Australia, yet there are few reports regarding vitamin D supplement use. Australian wholesale sales data was obtained for vitamin D supplements for the period 2000-2011. There has been a threefold increase in supplement sales over the past decade, whereby over A$94 million supplements containing vitamin D in Australia were sol...

The GOMOS Steering Front Assembly (SFA) is essentially a two axis pointing system. It comprises of a mirror (SMU), a Mechanism Drive Electronics unit (MDE) and a Steering Front Mechanism (SFM). Unlike many other pointing systems the SFA must maintain a line of sight stability of better than 3 microrads, while subjected to considerable microvibration disturbances from the host spacecraft. This p...

his article considers the supermarket manager’s problem of forecasting demand for a product as a function of the product’s attributes and of market control variables. To forecast sales on the stock keeping unit (SKU) level, a good model should account for product attributes, historical sales levels, and store specifics, and to control for marketing mix. One of the challenges here is that many v...

We consider the dynamic lot-sizing problem with finite capacity and possible lost sales for a process that could be kept warm at a unit variable cost for the next period t + 1 only if more than a threshold value Qt has been produced and would be cold, otherwise. Production with a cold process incurs a fixed positive setup cost, Kt and setup time, St, which may be positive. Setup costs and times...

The growth of Internet-based piracy has led to a wide-ranging debate over how copyright policy should be enforced in the digital era. While some enforcement approaches target consumers of pirated content with incentives or penalties, other approaches target the supply of piracy by shutting down Internet sites that serve as major conduits for pirated content. In this paper we analyze how one suc...

today’s b2b selling environment is characterized by much complexity. key drivers of this complexity include group sales efforts, multipart sales offerings and multibusiness unit participation on single deals (CFo research services 2010). Furthermore, the selling process is evolving from a transactional focus to consultative and enterpriselevel selling with a corresponding shift in competencies ...

We propose a model that estimates standard, enhanced, and flexible decompositions of price promotion effects based on store-level data. At present, decompositions of sales effects due to price promotions are available only for household models. These models decompose the sales elasticity into a category incidence elasticity, a brand choice elasticity and a quantity elasticity. We introduce a me...
