The high-tech versions have different properties that make them more comparable to materials such as stainless steel or aluminum, which are often more expensive still. New types of concrete offer the following advantages: 1. Intrinsically energy-ef cient. 2. Excellent insulation against wind and water. 3. Its high density means it stores heat during the day and releases it at night, preventing bridge decks from freezing in winter.

19. List the average balance of customers by city and short zip code (the first five digits of the zip code). Include only customers residing in Washington State (WA). In Microsoft Access, the expression left(CustZip, 5) returns the first five digits of the zip code. In Oracle, the expression substr(CustZip, 1, 5) returns the first five digits. 20. List the average balance and number of customers by city. Only include customers residing in Washington State (WA). Eliminate cities in the result with less than two customers. 21. List the number of unique short zip codes and average customer balance by city. Only include customers residing in Washington State (WA). Eliminate cities in the result in which the average balance is less than $100. In Microsoft Access, the expression left(CustZip, 5) returns the first five digits of the zip code. In Oracle, the expression substr(CustZip, 1, 5) returns the first five digits. (Note: this problem requires two SELECT statements in Access SQL or a nested query in the FROM clause see 9). 22. List the order number and total amount for orders placed on January 23, 2007. The total amount of an order is the sum of the quantity times the product price of each product on the order. 23. List the order number, order date, customer name (first and last), and total amount for orders placed on January 23, 2007. The total amount of an order is the sum of the quantity times the product price of each product on the order. 24. List the customer number, customer name (first and last), the sum of the quantity of products or dered, and the total order amount (sum of the product price times the quantity) for orders placed in January 2007. Only include products in which the product name contains the string Ink Jet or Laser. Only include customers who have ordered more than two Ink Jet or Laser products in January 2007. 25. List the product number, product name, sum of the quantity of products ordered, and total order amount (sum of the product price times the quantity) for orders placed in January 2007. Only include products that have more than five products ordered in January 2007. Sort the result in de scending order of the total amount. 26. List the order number, the order date, the customer number, the customer name (first and last), the customer state, and the shipping state (OrdState) in which the customer state differs from the shipping state. 27. List the employee number, the employee name (first and last), the commission rate, the super vising employee name (first and last), and the commission rate of the supervisor. 28. List the employee number, the employee name (first and last), and total amount of commissions on orders taken in January 2007. The amount of a commission is the sum of the dollar amount of products ordered times the commission rate of the employee. 29. List the union of customers and order recipients. Include the name, street, city, state, and zip in the result. You need to use the concatenation function to combine the first and last names so that they can be compared to the order recipient name. In Access SQL, the & symbol is the concate nation function. In Oracle SQL, the || symbol is the concatenation function. 30. List the first and last name of customers who have the same name (first and last) as an employee. 31. List the employee number and the name (first and last) of second-level subordinates (subordi nates of subordinates) of the employee named Thomas Johnson. 32. List the employee number and the name (first and last) of the first- and second-level subordinates of the employee named Thomas Johnson. To distinguish the level of subordinates, include a com puted column with the subordinate level (1 or 2). 33. Using a mix of the join operator and the cross product styles, list the names (first and last) of cus tomers who have placed orders taken by Amy Tang. Remove duplicate rows in the result. Note that the join operator style is supported only in Oracle versions 9i and beyond. 34. Using the join operator style, list the product name and the price of all products ordered by Beth Taylor in January 2007. Remove duplicate rows from the result. 35. For Colorado customers, compute the number of orders placed in January 2007. The result should include the customer number, last name, and number of orders placed in January 2007.

In 1998, the new Toshiba SD-7108 progressive scan DVD players, able to display almost twice the resolution as standard players from the same DVD, did not make it out of the warehouse. Concerns about lack of content protection on progressive scan output kept them there for another year. Demolishing opinions that dual-layer, double-sided discs (DVD-18s) would never be achieved, Warner Advanced Media Operations (WAMO) announced a new process to make them. This was immediately followed by rumors that the 195-minute Titanic would be the first DVD-18 release, since director James Cameron was insisting that the DVD contain both fullscreen and widescreen versions. It was no surprise that the rumors were false.

nomial indicates nite acceleration values yc at the ends (in nite jerk); vibrations result. This condition can be alleviated by the use of special ramps. However, if we desire that the cam acceleration curve have nite values of jerk, a fourth-order boundary condition [for follower y = f(q)] equal to zero at the ends is required. The 5-6-7-8-9 polynomial family having the following basic equation ful lls this condition: y = 1 - 126q 5 + 420q 6 - 540q 7 + 315q 8 - 70q 9 . (13.88)
