The United States Postal Service (USPS) delivers more than 200 billion items per year. Transporting these items in a timely and cost-efficient way is a key issue if USPS is to meet its service and financial goals. The Highway Corridor Analytic Program (HCAP) is a tool that aids transportation analysts in identifying cost saving opportunities in the USPS surface transportation network. Use of th...

BACKGROUND In order to ensure proper management of primary care (PC) services, the efficiency of the health professionals tasked with such services must be known. Patients with heart failure (HF) are characterized by advanced age, high co-morbidity and high resource utilization. OBJECTIVE To ascertain PC resource utilization by HF patients and variability in the management of such patients by...

This dissertation presents adaptation techniques that can achieve high spectral efficiency for single user multiple-input multiple-output (MIMO) systems. Two types of adaptation techniques, adaptive modulation and adaptive power allocation, are employed to adapt the rate and the transmit power to fading channels. We start by investigating the adaptive modulation subject to a certain bit-error-r...

When adapting services in a SOA environment, not only the validity of the adapter may be of importance, but also non-functional properties like the costs of the adapter. We introduce an approach for finding cost-efficient adapters based on the operating guideline, which characterizes all valid adapters for the given services.

Merge-and-shrink (M&S) is a framework to generate abstraction heuristics for cost-optimal planning. A recent approach computes simulation relations on a set of M&S abstractions in order to identify states that are better than others. This relation is then used for pruning states in the search when a “better” state is already known. We propose the usage of simulation relations inside the M&S fra...

Health care delivery in the developed world is in constant transformation. Structures and values are changing. New and more effective tools and technology are being used to identify and overcome diseases. Yet even if these new technologies are increasingly available to the public, not all of them have market potential. Cost efficiency is at the core of our health care system. Cost consideration...

This study aims to inspect and evaluate the integration of database queries and their use in e-commerce product searches. It has been observed that e-commerce is one of the most prominent trends, which have been emerged in the business world, for the past decade. E-commerce has gained tremendous popularity, as it offers higher flexibility, cost efficiency, effectiveness, and convenience, to bot...

For variable annuities, the cost of hedging must be taken into consideration when firms use the dynamic hedging strategy. In this paper, we study hedging strategies by assuming the hedge position follows a random walk with boundary conditions. We find that re-balancing delta to the initial position is always more cost-efficient than re-balancing it to the edge for a fixed transaction cost. Howe...
