Fire Fighting The longest truck-mounted ladder used by the Dallas Fire Department is 108 feet long and consists of four hydraulic sections. Gerald Travis, aerial expert for the department, indicates that the optimum operating angle of this ladder is 60°. The fire fighters find they need to reach the roof of an 84-foot burning building. Assume the ladder is mounted 8 feet above the ground.

a. Draw a labeled diagram of the situation.

b. How far from the building should the base of the ladder be placed to achieve the optimum operating angle?

c. How far should the ladder be extended to reach the roof?

Abstract
This document gives some ideas about how to
write a project proposal, and provides a template for a proposal. You should
discuss your proposal with your advisor.

Your proposal should be
about 4 pages long.

Your project proposal should cover the
following points:
• the
problem that you are going to solve;
• how
you plan to solve your problem;
• how
you intend to evaluate your solution; and
• any
resource requirements for your project such as software, hardware or other
resources that will be needed in the course of the project.

Particularly, your proposal
should follow this format STRICTLY!

IMPORTANT NOTE: your project must
involve one of the following:

• Research
(using conference and journal publications), producing a publishable paper by
you. You must develop simulation code to support and validate your claims and
conclusions
• Code
development: You must develop original code to implement the project – no third
party code is allowed unless clearly indicated – and majority of the code
should be yours.
• Other
engineering implementation project as approved by your advisor

Proposals involving learning a
software package, evaluating a product etc. are unacceptable and will be
rejected.

Also please note that

Also please note that

The Problem
In this section you should give a brief
description of the problem itself. You want to briefly explain the problem, why
it is important to solve the problem and define your project aims. After
reading this section, the reader should understand why it is a problem, believe
that it is important to solve and have a clear idea of the aims of your
project.

When describing the aims of the project,
you should avoid vague, unmeasurable words like ‘analyse’, ‘investigate’,
‘describe’, and use specific, measurable words like ‘implement’, ‘demonstrate’,
‘show’, ‘prove’. For example:

Good: The
aim of this project is to implement and evaluate a management system for
network switches;

is much better than:

Bad: The
aim of this project is to investigate management systems for network switches.

In the second case there is no idea of how
much work is involved, and you will never
know whether you have finished. You and
your supervisor (and the markers of your project) may have very different ideas
about what such an ‘investigation’ involves. Of course, it is possible that the
task you set yourself is not achievable, but if you are clear from the outset
this is less likely, and will more easily be corrected.
Why This Project?
Describe the importance of this problem and
why it justifies doing a masters level project on it. Also you must do some
preliminary research and state whether a solution to this problem has been
attempted by anyone in the past or you are the first one proposing an original
solution.

Proposed Solution
In this section you will explain how solve
the problem, that is, how you intend to carry the project out. At this early
stage you need to be both clear about what you are going to do and flexible
enough to adapt to changing circumstances. Making an early plan will not
prevent you from running into trouble, but it will help you identify possible
problems early. Be specific about your development tools, that is what
programming language, what development tools, operating systems, etc. You also
have to be very specific as to what the final deliverable will be. As an
example, you should say, “the final project deliverable will be an Android
based app that receives data from XYZ sensors attached to the smart phone to
display and transmit the processed data to central database implemented in
Java.â€

Proposed Timeline
An integral component of the course is
project management. This includes the planning process involves producing a
timetable for when the work is actually going to be done.

Each part of the project should produce
some output. For example you might plan on
spending two weeks on background reading:
the output of this will be a bibliography, and a possibly a literature survey
for your report. Indeed, if you take the advice given above about having
specific, measurable goals, you should describe this part of your project as:
Good:
Produce bibliography (est: 2 weeks)

rather than:
Bad:
Background reading (est: 2 weeks)

You MUST include a timetable as follows
with your proposal: (please note that the content I have put are intended to be
an example – you must fill the table yourselves)

My Belle Cosmetics is a large business that has sales well ahead of any other regional cosmetics firm. As an organization, it is very sensitive to color, because it introduces new color lines in its products every fall and spring. The company has recently begun using technology to electronically show in-store customers how they appear in different shades of cosmetics without requiring them to actually apply the cosmetics.

a. Design and draw a representation of a display screen that can be used by sales clerks at a counter to try many shades of lipstick and makeup on an individual customer very quickly and with a high degree of accuracy. Input from customers should be their hair color, the color of their favorite clothing, and their typical environmental lighting (fluorescent, incandescent, outdoor, and so on)

b. Design and draw a representation of a display screen that is equivalent to the one in Problem 7a but that vividly demonstrates to decision makers in My Belle how color improves the understandability of the screen.

c. One of the affiliates My Belle has on the Web is a large department store chain. In a paragraph, describe how the display screen in Problem 7a can be altered so that an individual can use it and My Belle can put it on the department store’s ecommerce site to attract customers.

Problem 7a:
Design and draw a representation of a display screen that can be used by sales clerks at a counter to try many shades of lipstick and makeup on an individual customer very quickly and with a high degree of accuracy. Input from customers should be their hair color, the color of their favorite clothing, and their typical environmental lighting (fluorescent, incandescent, outdoor, and so on)

Consider the use of timestamp ordering with each of the example inter leavings of transactions T and U in Exercise 16.9. Initial values of ai and aj are 10 and 20, respectively, and initial read and write timestamps are t0. Assume that each transaction opens and obtains a timestamp just before its first operation; for example, in (a) T and U get timestamps t1 and t2, respectively, where t0 1 2. Describe in order of increasing time the effects of each operation of T and U. For each operation, state the following:

i) Whether the operation may proceed according to the write or read rule;

ii) When timestamps are assigned to transactions or objects;

iii) When tentative objects are created and when their values are set.

What are the final values of the objects and their timestamps?

Exercise 16.9

The transactions T and U at the server in Exercise 16.8 are defined as follows:

Initial values of ai and aj are 10 and 20, respectively. Which of the following inter leavings are serially equivalent, and which could occur with two-phase locking?

Exercise 16.8

Explain why serial equivalence requires that once a transaction has released a lock on an object, it is not allowed to obtain any more locks.

The transactions T and U are defined as follows:

Describe an interleaving of the transactions T and U in which locks are released early with the effect that the interleaving is not serially equivalent.

3.  Why are decisions more common in prescriptive process models than in descriptive process models?

Decisions are more common in prescriptive process models because a prescriptive process model is trying to cover what is done in alternative situations. Thus, it may need to specify the decision that is used to decide what to do next. A descriptive process model describes what happened, and alternative actions are usually not included.

4.  Why should tasks in a process model be separated by an artifact?

If one process follows another process, some information or document from the first process is needed by the second. If this were not true, then the two processes would be independent of each other and one would not follow the other. This information or document should be identified and  documented.
