1. Study the Connecting to an XE Oracle Server document available by hyperlink from the course web site. Logon to your XE instance server account using windows/Linux/Unix command line. After logging on, answer following questions:

What is your home directory of ORACLE_HOME

What is your ORACLE_SID

What is you ORACLE_BASE directory?

2. Move to the ORACLE_HOME subdirectory. Examine the other subdirectories under ORACLE_HOME. Look in the dbs subdirectory that stores the PFILE for the XE database. The example PFILE is named init.ora. The init.ora file is a template that you can use to create your own PFILE. Locate the init.ora files

What is the database block size specified for the XE database with this init.ora file?

How many control files are defined and what are their names?

What version of Oracle is this database set to support for compatibility of features?

What is the name of the tablespace that supports UNDO management?

3. The XE database consists of multiple datafiles and other files. Explore and find and List the location of the XE database files

One of your staff, Brown criticized his teammate, Black about his slow work performance because he is illiterate. Black got angry and rebutted with some sarcastic remarks. Black then dashed towards Brown and started screaming at the top of his voice.

You are their Supervisor and witnessed the whole incident. How can apply the Conflict Management Strategies to resolve this issue?

Deliverable 2 - Implementation of an Enterprise Architecture

Outline a plan to create an enterprise architecture for a cloud-based web application server and SQL Database Sever. Including the necessary development environment, production environment, and implementation schedule including a critical path.

Competency

Summarize the common elements of enterprise architectures.

Scenario

You work as a developer for Solutions Inc. Your client, Universal Widgets, is planning to implement a cloud-based solution for their IoT(Internet of Things) connected devices. These devices are designed to monitor air quality in a home for the homeowner's heating and air system. These devices also are able to detect the carbon dioxide levels, presence of smoke, and notify homeowner's when to change the air filters.

The majority of Universal Widgets' customers will use this new solution. This is predicted to increase their sales and their customer base. However, because of the public safety features that are offered by this application, up-time for customers will need to be no less than 99.999% each month. Therefore, any implementation that occurs to the production environment needs to be properly tested prior to implementation.

Instructions

Develop an implementation plan for this cloud-based solution. This plan must include the following elements:

• A brief breakdown of the primary tasks needed to create a development environment, and also a full production environment.
• The critical path for both environments through to completion.
• Evaluation of the constraints and issues at the enterprise level including scenarios that demonstrate pros and cons of any implementation, software update, or change.

The numerical aperture of an instrument is 0.969. How far apart are the lines on a certain shell if they are just barely resolved when viewed with green light (548 nm)?

Use C++, Java, or Python3 to create your own algorithm to complete a computing task.

There are four steps to algorithm methodology. Discuss your algorithm design in relation to these four steps and describe how you went through each step of the methodology to create your algorithm.

From the earliest years of settlement, we see how different populations of Europeans had vastly different goals and reasons for coming to the “New World.” Cite examples of the different reasons Europeans made the perilous journey to North America and where they settled.

1. write a class called football player with variables number, weight, height inside. Then make child classes for football player, one called defensive player, which will have sacks and interceptions as variables, and offensive player, which will have yards and fumbles as variables

(Multiple choice)
Which one of the following statements is true? Explain why T/F for each.
(a) In fiber reinforced composites, the dispersed phase will not have the same composition as
the matrix phase.
(b) When continuous-fiber reinforced composites are loaded longitudinally, the stress in the
fibers equals the stress in the matrix.
(c) Sandwich panels are useful because of their high weight-to-stiffness ratio.
(d) Approximately 30% of the overall strength of fiberglass is contributed by the matrix.
(e) The stiffness of aligned discontinuous-fiber reinforced composites loaded along the fiber
direction depends on the weight fraction of matrix in the composite.

1 Consider a program for the determination of Previous date. Its input is a triple of day, month and year with the values in the range

1 ≤ month ≤ 12

1 ≤ day ≤ 31

2000 ≤ year ≤ 2125

The possible outputs are “Previous date” and “Invalid input date”.

Design the test cases using the following:

1. [50 Marks] Decision table-based testing.
2. [50 Marks] Design the worst-case testing.

Show the full details to apply the testing part

1. How do facilitated transport and active transport differ? How do they look similar?

2. How do simple diffusion and facilitated transport differ? How do they look similar?

3. What is the difference between diffusion and osmosis?

How would you use the learning theory and instructional design model to develop instructional technology and the appropriate assessments?

A 1.5 kg block of wood is launched up a wooden ramp that has a 40-degree incline. The initial speed of the block is 12 m/s. The coefficient of static friction is 0.4 and the coefficient of kinetic friction is 0.20. Ignore air resistance.
A) Draw the incline with the block at the bottom of the ramp and at the top of its slide. Label with a coordinate system. List all known quantities.
B) Draw free body diagrams for the block sliding up the incline and down the incline. Label all forces and acceleration.
C) What is the normal force on the block?
D) What is the acceleration as the block moves up the ramp?
E) How far up the ramp does the block travel?
F) What is the static frictional force on the block when it stops? Is it enough to hold the block there?

A nearsighted man uses his ideally prescribed eyeglasses that have a refractive power of −2.60 diopters. He would like a prescription for contact lenses. What is the correct contact lens prescription if he normally wears his eyeglasses a distance of 2.7 cm from his eyes?

Suppose a biochemist decided to use a HEPES buffer system to purify her His-tagged protein. HEPES is a sulfonic acid with a relevant pKa of 7.5. What volume of 1M NaOH would she need to add to a 250mL solution of 20mM HEPES to raise the pH from 7.5 to 8.0 (remember the HEPES is a weak acid).
