The importance of content delivery networks (CDN) continues to rise with the exponential increase in generation and consumption electronic media. In order ensure high quality experience, CDNs often deploy cache servers that capable storing some popular files close users. Such edge caching solutions not only availability, but also result higher download rates lower latency. Different from classi...

We examine a multiperiod capacity allocation model with upgrading. There are multiple product types, corresponding to multiple classes of demand, and the firm purchases capacity of each product before the first period. Within each period, after demand arrives, products are allocated to customers. Customers who arrive to find that their product has been depleted can be upgraded by at most one le...

Dynamic memory management has been a performance bottleneck in many operating systems including multithreaded and real-time operating systems. Moreover, recent advances in software engineering, such as graphical user interface and object-oriented programming, have caused applications to become more memory intensive. The growing popularity of these operating systems and applications increases th...

We introduce the design methodology known as dynamic power management (DPM), targtting the maximization of power efficiency under performance constroints for electronic s,stemt. We first describe the basic motivations for implementing DPM, then we surve'l several power management ,chemes. Finally, we provide guidelines to assessing the potential impact of a DPM scheme for a given target system.
