CS547 Wireless Networking and Security Homework 02
Question 1: Simplify the following expression:
sin(2𝜋𝜋𝜋𝜋𝜋𝜋) + sin(2𝜋𝜋𝜋𝜋𝜋𝜋 − 𝜋𝜋) Question 2: Calculate the period of the following:
a) the function 𝜋𝜋(𝜋𝜋) = (10. cos 𝜋𝜋)2 b) the frequency of a telephone line which is 3 kHz
Question 3: A communication channel is designed to have a capacity of 300 Mbps with a bandwidth of 3 MHz. Calculate the Signal-to-Noise ratio that is required to achieve this data rate. Question 4: Given the following parameters for a switching network: N = number of hops between two end-point stations L = message length in bits B = data rate in bits per second (bps) P = fixed packet size in bits H = header size for each packet in bits S = call setup time (for circuit switching) in seconds D = propagation delay per hop in seconds For N=4, L=3200, B=9600, P=1024, H=16, S=0.2, D=0.001, compute the end-to-end delay for circuit switching and datagram packet switching.

what does the future hold for IT consulting? Which factors will shape the future of the industry?
Purpose
Over the years, the IT consulting industry has responded creatively to the changing needs of clients, leading to the growth of a thriving industry and, for the most part reactive to client demands. IT consulting firms have readily grown and shrunk in response to client demands.
The fortunes of IT consulting firms, like most firms, were impacted by the recent global recession. IT budgets were cut, and most high-profile projects were suspended, most notably in financial services. Having discussed the past and the present, what does the future hold for IT consulting? Which factors will shape the future of the industry?

Explain the pathophysiology of mood and anxiety disorders in children and adolescents
Mood and Anxiety Disorders in Children and Adolescents
School and going out with my friends used to be fun, but not anymore. Mom keeps telling me just to go out and have fun, but I don’t see the point of trying. All my friends are better than I am. I keep having these headaches and just feel worthless. I used to get As and Bs in school, but not anymore. I can’t concentrate at school. I would rather be at home sleeping.
—Madison, age 16
Mood and anxiety disorders can be particularly challenging to address in childhood and adolescence for many reasons. Children may not be able to fully express or understand their feelings and behaviors. Parents may misattribute or not recognize signs and symptoms. The symptoms of disorders also vary when present in children as opposed to adults. The PMHNP needs to know how to diagnose these conditions and must understand the importance of integrating medication management strategies with both individual and family therapy to optimize treatment outcomes.
Learning Objectives
Students will:
· Explain signs and symptoms of mood and anxiety disorders in children and adolescents
· Explain the pathophysiology of mood and anxiety disorders in children and adolescents
· Explain diagnosis and treatment methods for mood and anxiety disorders in children and adolescents
· Develop patient education materials for mood and anxiety disorders in children and adolescents

Explain the role and purpose of NIMS and ICS.
Instructions
Visit the following URL for additional information on the Federal Emergency Management Agency (FEMA), the National Incident Management System (NIMS), and the Incident Command System (ICS):
https://www.fema.gov/pdf/emergency/nims/nimsfaqs.pdf
NIMS and ICS play vital roles in emergency management response and resiliency and reactionary-based planning at the local, state, and federal levels. Further, in a chemical, biological, radiological, nuclear, explosive (CBRNE) event, both NIMS and ICS must be utilized.
In a two-page reflection paper, complete the following sections:
Part I: Explain the role and purpose of NIMS and ICS. Further, NIMS and ICS can be applied to most emergency incidents that occur to include weapons of mass destruction scenarios involving chemical, biological, radiological, nuclear, and explosive occurrences.
Part II: Create a table-top exercise incident involving a weapons of mass destruction event that can be administered at a law enforcement agency. Include the following: type of incident, agencies involved, location of incident, roles of agencies, how response should take place, and the role of NIMS and ICS. How is interoperability and resource management applied to your scenario? Finally, reflect on why table-top exercises are important to complete in the criminal justice and homeland security sectors.
Adhere to APA Style when creating citations and references for this assignment. APA formatting, however, is not necessary.
