Napco in 2009: Sales Growth in the Middle East

The background regarding sales for the two-case series in 2009: Relaunching the Five Stars Restaurants Project cases A and B, is presented in this case. This case and the two-part series are designed to be used as a set; however, sufficient background is provided in the A case for instructors to use the two-part series independently of this background case. Excerpt UVA-OM-1458 Rev. Mar. 14, 2012 NAPCO IN 2009: SALES GROWTH IN THE MIDDLE EAST Peter Hatem was taking the long flight to Riyadh, Saudi Arabia, out of Washington-Dulles International Airport. He settled into his seat and began thinking about the new ideas that he had recently generated to achieve 20% sales growth for the National Paper Products Company (Napco) in Gulf Cooperation Council (GCC) countries. Hatem was returning from the Darden Graduate School of Business Administration where he had just completed the summer 2009 Executive Program (TEP). During TEP, he had the opportunity to reexamine his plans for a pilot sales force development initiative he called the Five Stars Restaurants Project. Hatem was the area general manager for Napco in Riyadh and for the Napco Consumer Products Company in Dammam. Napco operated throughout the Middle East and in Egypt and the United Kingdom (Figure 1).

Source apportionment of time- and size-resolved ambient particulate matter

Size- and time-resolved particulate matter samples collected using eight-stage Davis Rotating-drum Universal-size-cut Monitoring (DRUM) impactors at the Washington-Dulles International Airport were analyzed for the elemental composition using synchrotron X-ray fluorescence. A physically realistic three-way factor analysis model consisting of the outer products of matrices (profiles) times a vector of mass contributions was applied to these data. The problem was solved using a weighted alternating least squares method. Five major emission sources: soil, road salt, aircraft landings, transported secondary sulfate, and local sulfate/construction were identified. The study shows that time- and size-resolved RDI data can assist in the identification of the airport emission sources and atmospheric processes leading to the observed ambient concentrations.

Metric assessment of subjective annoyance due to low frequency aircraft noise

A low frequency noise study was conducted at the Pennsylvania State University to investigate human response to the low frequency content of aviation noise. Metric assessment included level based and loudness metrics, including time‐varying loudness. Current predictive noise models and metrics may underestimate the impact of low‐frequency noise produced by aviation noise. Assessing the role of low frequency noise on human response will facilitate understanding how this type of noise can impact communities. Indoor recordings of aircraft arrivals and departures at Washington Dulles International Airport made in 2004 were used to assess subjective noise annoyance. These recordings and low‐frequency variants of these recordings were reproduced for subjects through the Gulfstream Supersonic Acoustic Signature Simulator II (SASS II); the signatures were then rated for annoyance. Subjective judgments were statistically analyzed and compared against objective metrics that were calculated for each signature. Results are shown that all things being equal higher levels of low‐frequency content in aircraft noise can result in increased annoyance in subjects. The C‐weighted sound exposure level was found to correlate well with the subjective annoyance response.

9.2.1 Optimized Airport Security Infrastructure System (OASIS)

AbstractIt has been suggested that the current security measures being implemented in airports around the country produce “soft targets” in the form of lengthy queues. These soft targets heighten the risk of a terrorist attack within airport premises that could potentially have the same impact as destroying a commercial flight. Using Washington Dulles International Airport as a case study, this study examines the security measures being implemented in the airport and designs a methodology that will result in improved allocation and usage of security resources. Two alternatives are designed that make use of layered, defense‐in‐depth security measures that aim to deter terrorist attacks by using the concept of unpredictability. Models of these alternatives are built and the best alternative is selected by analyzing simulation outputs and evaluating them based on a value function. At the end of the study, an Optimized Airport Security Infrastructure System (OASIS) that will provide a more efficient and reliable method for screening passengers and their luggage is proposed.

Vibration and rattle impact due to low frequency noise investigated at Dulles airport

A noise study was conducted at Washington Dulles International Airport to further investigate the noise and vibration impact of thrust reversers and start of takeoff roll on communities near runways. Two different houses located on the airport property were instrumented with outdoor and indoor microphones and accelerometers mounted inside on walls, windows and floor. This presentation will discuss both the experimental design and data obtained from the two different structures. Correlations between plane types, outdoor signatures and acceleration levels are considered. The outdoor signatures and acceleration levels are used to investigate the conditions under which rattle of a loosely coupled window is observed. Additionally, the design of a subsequent subjective study to examine the effects of rattle on human perception will be discussed. The combination of the objective measurements with the results of the subjective study is intended to give a better understanding of community impact due to airport noi...

Development of a Discriminant Analysis Mixed Precipitation (DAMP) Forecast Model for Mid-Atlantic Winter Storms

Abstract The frequency of “wintry mix” precipitation—freezing rain and ice pellets—is considerable in the mid-Atlantic region of the United States. Despite the fact that the general conditions necessary to support the various winter precipitation types have been known for years, in that region, the proper forecast of type and duration of winter precipitation is one of the most difficult challenges in operational meteorology, with extensive public safety and economic ramifications. The purpose of this project is to report on an improved methodology for winter precipitation forecasts. This study analyzed precipitation type and surface temperature data from NOAA’s hourly surface airway observations and temperatures and heights for all mandatory and significant levels from NOAA’s Radiosonde Data of North America from Washington Dulles International Airport, Virginia (1962–95), and Greensboro, North Carolina (1948–95). Precipitation that occurred within 2 h of a sounding for the months November through March w...

Relaxing the perimeter and high-density rules: implications for Washington Dulles International Airport

The Perimeter and High-Density Rules have been the foundation upon which the physically limited capacity of Ronald Reagan Washington National Airport has been allocated. The perimeter rule at National Airport requires nonstop scheduled airline flights from that airport to serve destinations within a 1250-mile perimeter. The distance limit was initially introduced for a combination of reasons including environmental conservation (especially with respect to noise nuisance) and the desire to offer some protection for other airports in the Washington DC area as they built up traffic to reach a critical mass. The US Senate has recently taken actions to adjust the perimeter rule at National Airport. Any major relaxing of the rule will have implications for the other major airports in the National Capital Region; namely Washington Dulles International Airport and Baltimore–Washington International Airport. The resultant knock-on effects of this development on the wider economy of the region is examined here. The main attention of the paper is on the impact of any major change in the perimeter rule on Washington Dulles International Airport, and on the subsequent knock-on effects this would have on the region's employment level and structure.

The Making of Virginia Architecture.

This book covers the history of architecture in Virginia, from the early colonial period to the present. It aims to bring the architectural process to life, pairing the architects' own drawings with photographs of the finished buildings, and concludes a nationwide search that uncovers some 200 early architectural drawings from 1719 to 1870. The long tradition of architecture in Virginia began with the earliest structures at the Jamestown settlement in 1607 and continues today with some of the most advanced buildings yet completed anywhere. The state boasts representative works by nearly every major American architect - William Buckland, Ralph Adams Cram, Alexander J. Davis, Bertram Grosvenor Goodhue, Richard Morris Hunt, Minard Lefever, Robert Mills, Richard Neutra, John Russell Pope, James Renwick, William Strickland, Thomas U. Walter, Stanford White, Eero Saarinen and Frank Lloyd Wright among them. In its legendary landmarks - Mount Vernon, Monticello, the Virginia Capitol in Richmond, the James River plantation mansions, Washington National Airport and Dulles International Airport - as well as in the homes, churches, stores and office buildings across the state, Virginia's architecture is a mirror of the many expressions of America's built environment. "The Making of Virginia Architecture" invites the reader on a journey through the eye and mind of the architect, from the very drawings that give shape and form to the idea, through the tracks and traces found in long-lost letters, office records, architects' drawings and other primary sources. Many of the architectural drawings are works of art in themselves, such as those of B. Henry Latrobe and Alexander J. Davis. Others - such as the almost crude drawings of Thomas Jefferson, with their notes and erasures - fall into the category of rare documents, showing the thought processes of a highly original designer, albeit an unskilled draughtsman. As the book compares the architectural idea to the finished buildings, it brings history to life through the people and patrons behind Virginia's architecture and through the changing tools and technology of the architect, from the first rough sketch on the back of a handwritten contract to the complex wonders of the computer printout.

Fueling System for Dulles International Airport

The growth in size, speed, and range of aircraft has brought a growth in the consumption of fuel at such a rate that underground pipes and hydrant fuel systems are a necessity at large, busy airports. The design of the aircraft fueling systems is dependent of aircraft layouts, frequency of aircraft landings, types of aircraft, and the number of grades or suppliers of fuels. Fueling system design must also incorporate flexibility for changing the grade and/or supplier of fuel and for future expansion. The fueling system at Washington's Dulles International Airport was somewhat simplified because of the airport's unique passenger handline facilities. The large quantities of fuel required on the apron indicated that a hydrant system was necessary. A direct pumping fueling system that segregated fuel by grade rather than by airline was determined to be best. The control system required a minimum of operator attendance while at the same time allowing for rapid communication of system conditions to the operator during routine checks or when a malfunction occurs.
