The tow path is currently used part of the Mohawk-Hudson bikeway and is used bymany local people for biking and walking. The lock was used to raise and lower canal boatsbetween two segments of the Enlarged Erie Canal. Lock 23 was the first lock west ofSchenectady, NY and the busiest lock on the canal. The locks were built in the 1840’s andexpanded in the 1880’s. The 1840’s lock chambers are 20 feet deep, 17 feet wide and 110 feetlong with a 20 foot wide “island” separating the locks.

In 1999, 55 students accessed the system 1470 times inspring of 1999 and 100 students 2100 times so far in fall of 1999. The utilization of the system isapproximately 23 times per student per semester and appears to be similar each semester. Thepeaks of its use are observed just around midterms and final exams due to students waiting fortheir grades to be posted before they receive their tests back, or final grades in the mail.Bibliography1.

Atransition is defined as zero transition for specific data input of a flip-flop if it isnecessary to apply logical 0 to that input to see the flip-flop going through thistransition. For example, for an RS flip-flop to go through α transition, 0 to 1, it isnecessary to apply logical 1 to the S input and logical 0 to the R input. Therefore, αtransition is considered to be essential transition for the S input and zero transition forthe R input. Page 5.250.4To explain how to use this method to design synchronous

Geometric Properties of Shapes moduleV. Design and Analysis ToolsA typical module in VLSM is equipped with a design and analysis tool that allows a student todevelop a design model for which it provides a step by step solution. An example of this is theShape Design and Analysis Tool (S-DAT) in the Geometric Properties of Shapes module.Developed using Sun’s JDK 1.2 software, S-DAT can be used to draw a rather complexgeometric shape, and to obtain its properties such as centroid, moments of inertia, product ofinertia, etc. Figure 5-a shows the graphical user interface (GUI) for S-DAT. The icons on theright show the ten built-in templates. They can be used individually or in combination togenerate a more complex shape. (a
