WPI Engineers football. The WPI Engineers football team represents Worcester Polytechnic Institute (WPI) in the sport of American football. The Engineers compete in Division III (DIII) of the National Collegiate Athletics Association (NCAA) and the NEWMAC. WPI's football program is one of the oldest in the country. The team has been coached by Chris Robertson since the 2010 season.

WPI plays its home games at Alumni Stadium, located on the campus in Worcester, Massachusetts, with a capacity of 2,000.

History
Prior to competing in collegiate football, WPI played association football (now known as the sport of soccer) from 1874 to 1876 and American rugby from 1877 to 1881. Starting in 1882, WPI attempted to play football as a sport. It was not until 1885 that the football team was taken seriously. The 1887 season was the first in which the team competed as a varsity sport. Following their outstanding performance in the 1888 season, the Engineers were invited to join a football league of small New England colleges, but the faculty refused the idea and barred the team from playing any away games. The Institute's opinion of football would improve by the turn of the century and give more support to the team.

Bowl games
WPI has appeared in four bowl games and has a 2–2 record.

Carl R. Deckard. Carl Robert Deckard, Ph.D, ME (1961 - December 23, 2019) was an American inventor, teacher, and businessman, best known for inventing and developing Selective Laser Sintering (SLS), a method of 3D printing. He died at the age of 58, on 23 December 2019.

Career
Deckard initially came up with the idea for SLS as an undergraduate at the University of Texas at Austin (UT Austin). He continued developing the technology as a Masters and PhD student with the help of Dr. Joe Beaman, a professor at UT Austin.
After several years of trial-and-error, Deckard's machine was capable of manufacturing real parts.  He licensed the technology from UT Austin and co-founded Desk Top Manufacturing (DTM) Corp. in 1987. DTM Corp. specialized in rapid prototyping and manufacturing systems for manufacturers and service bureaus.  DTM Corp. was acquired by 3D Systems in 2001 at a $45 million valuation.
Deckard became an engineering professor at Clemson University after DTM's acquisition. After three and a half years, Deckard returned to Austin to work on the Deckard Engine, a four-stroke engine aimed at replacing emission-emitting two-stroke engines in small, hand-held products.

The majority of Deckard's work was in the additive manufacturing industry. In 2012, Deckard co-founded Structured Polymers LLC, a company that develops novel polymers for SLS machines.

Frank Pellegrino (inventor). Frank G. Pellegrino (1923 – 2008) was an American engineer, inventor, and industrialist. He served as president of the General Fibre Company. During his tenure, General Fibre became the largest manufacturer of duck decoy models in the United States, producing over a million per year in the 1950s.  Pellegrino also negotiated the sale of the International Hat Company to Interco, Inc.  Additionally, he created a variety of inventions related to the plastic molding industry. Most notably, Pellegrino invented automated assembly line machines in the formation of plastic objects.  These machines were used by General Fibre in the production of a variety of plastic models, duck decoys, and Michelob paraphernalia throughout the 1960s to 1980s.

Life

Pellegrino was born in St. Louis, Missouri. He was an electrical engineering graduate of Iowa State University via the V-12 Naval College Training Program.  He was the son of Ida Kropp and Frank Pellegrino, the philanthropist and president of the International Hat Company.  He served as an American naval officer, in the Pacific theater, during World War II.  After World War II, Pellegrino was stationed in Japan as part of the US occupation and rebuilding effort.  In 1948, he returned to St. Louis and married into the high society, old money Henry family; marrying Virginia Anne Henry, daughter of Harry W. Henry, president of the Graham Paper Company.  That same year, Pellegrino was hired as vice president of General Fibre by President George Tilles, Jr.

In the mid-1950s, Pellegrino became president of General Fiber, following the retirement of Lewis Tilles Apple. The company had manufactured the original M1 fiber helmet liner in 1941 before moving into the production of fiber components for the military pressed fiber sun helmets used by American soldiers during World War II. After the war ended, the company required a production transition back to civilian orders. In 1946, General Fibre switched into the duck, goose, and swan decoy model market.  The models were used by hunters to attract prey.  During his management of the company, General Fiber reached its peak production of these models in the late 1950s and early 1960s. However, it was during this time that Pellegrino began shifting the company's business model out of the production of wood fiber pulp products into the emerging plastics and plastic molding industry.

In the early 1960s, he designed and engineered new automated machines in the manufacturing of plastic goods. These included plastic models, construction helmets, and various products for the Anheuser-Busch company.

Pellegrino died in 2008.

Hazardous materials apparatus. A hazardous material (hazmat) apparatus is a vehicle used by emergency services to respond to calls involving potentially hazardous materials. These vehicles are customized to fit the needs of the agency responsible for the apparatus, which may be a rescue squad, fire department, emergency medical services, law enforcement agency, or military.

A typical hazmat vehicle will have a portion dedicated to a command and communications center. Often fitted with computers, televisions, two-way radios and other equipment. This command center is usually located in a portion of the vehicle that slides out or expands much like is found on a typical recreational vehicle.

Hazmat vehicles also often come with a portable lab complete with sinks and fume hoods that allow for the analysis of samples collected at the scene. Essentially a mobile laboratory, this allows early on-site scientific analysis and monitoring to speed up the detection process and allow firefighters and other emergency services to provide the correct response for the particular incident.

In the United States, NFPA regulation 471 Recommended Practice For Responding To Hazardous Materials Incidents outlines the equipment required for a hazmat apparatus including a radiation detector, pH meter and other air sampling devices.

Some equipment found on hazmat vehicles include:
 Containment booms to contain spills of non-miscible materials
 Personal protective equipment such as self-contained breathing apparatus and hazmat suits

The Abingdon Co.. The Abingdon Company is a watch and aviation products manufacturer founded in Oregon in 2007 by Chelsea Abingdon Welch. The company manufactures what it describes as the first aviation watch specifically designed for women.

History
The Abingdon Co. began during a round table dinner conversation between a mix of women pilots and airplane mechanics. Pilot and company founder Chelsea Abingdon Welch listened as her colleagues repeatedly expressed their desires for a fully functional aviator's watch that was "fashionable, versatile and, most importantly, made for women".  Abingdon first spent over 11 months designing two models—the Jackie and the Amelia—and then launched the company on November 3, 2007.

The Abingdon Co. also manufactures travel and dive watches, with various features:

 The Amelia features an E6B flight calculator and Zulu time (quartz movement)
 The Jackie features an E6B flight calculator and a chronograph and the outer case back has over 64 twinkling zirconia rivets (quartz movement)
 The Katherine features an ATIS bezel and a chronograph (quartz movement)
 The Elise features a tri-time zone (quartz movement)
 The Marina is a fully automatic dive watch with a world timer, wet suit expander band as well as a silicone band, titanium band, and a diver's outer bezel.

Assemble-to-order system. In applied probability, an assemble-to-order system is a model of a warehouse operating a build to order policy where products are assembled from components only once an order has been made.
The time to assemble a product from components is negligible, but the time to create components is significant (for example, they must be ordered from a supplier).

Research typically focuses on finding good policies for inventory levels and on the impact of different configurations (such as having more shared parts). The special case of only one product is an assembly system, the case of just once component is a distribution system.

Model definition

Single period model

This case is a generalisation of the newsvendor model (which has only one component and one product). The problem involves three stages and we give one formation of the problem below

 components acquired
 demand realized
 components allocated, products produced

We use the following notation

In the final stage when demands are known the optimization problem faced is to 

and we can therefore write the optimization problem at the first stage as

with x0 representing the starting inventory vector and c the cost function for acquiring the components.

Continuous time

In continuous time orders for products arrive according to a Poisson process and the time required to produce components are independent and identically distributed for each component. Two problems typically studied in this system are to minimize the expected backlog of orders subject to a constraint on the component inventory, and to minimize the expected component inventory subject to constraints on the rate at which orders must be completed.
