The Strategy Development Guide defines a road map that PUCs can follow to design and implement

a structured approach for long-term engagement with utilities on cybersecurity matters. The guide

includes examples from PUCs that demonstrate the process steps and highlights the drivers of

successful outcomes. (2018)

2. Understanding Cybersecurity Preparedness: Questions for Utilities

The Questions for Utilities provides a set of comprehensive, context-sensitive questions that PUCs

can ask a utility to gain a detailed understanding of its current cybersecurity risk management

program and practices. The questions build upon and add to those included in previous NARUC

publications. (2019)

3. Cybersecurity Preparedness Evaluation Tool (CPET)

The CPET provides a structured approach for PUCs to use in assessing the maturity of a utility’s

cybersecurity risk management program and gauging capability improvements over time. The

CPET is designed to be used with the Questions for Utilities on an iterative basis to help PUCs

identify cybersecurity gaps, spur utilities’ adoption of additional mitigation strategies, and inform

cybersecurity investment decisions. (2019)

4. Cybersecurity Tabletop Exercise (TTX) Guide

This guide details the steps that PUCs can take to design and execute an exercise to examine utilities’

and other stakeholders’ readiness to respond to and recover from a cybersecurity incident. The

guide also is helpful to PUCs seeking to exercise their own cybersecurity strategies and capabilities.

Exercise scenarios and examples are included. (2020)

5. Cybersecurity Glossary

The Glossary contains cybersecurity terms used throughout the Cybersecurity Manual, as well as

“terms of art” that utilities may use during discussions with PUCs. (2019)

Components of the Cybersecurity Manual can be used individually but are designed to work together.

NARUC’s intent is to provide a comprehensive set of assessment tools that, when applied, provide a consistent,

complete view of utilities’ cybersecurity preparedness.

a. population, units, sample

Explanation:

In a survey or in a research, population is defined as the total number of people or total number of items in the group that we want to study in a research. It is the entire pool from where a sample is drawn.

An unit is defined as the individual members for which the information or data is collected.

A sample is defined is defined as the group or part of the selection from where the information or data is to be obtained.

The overall group of people should be known as the population.

The individual members should be units

And, the sample represents the part that should be examined.

The population refers to the total no of people or items that are required to be studied for the research purpose. In this, the sample should be drawn. The unit refers to the individual members due to which the data should be collected. And, the sample means the portion of the selection from where the data should be collected.

Therefore, the option a is correct.

Answer:

power = 0

Explanation:

Given data:

cosine waveform; y(t)  = 10cos(120πt)

peak value = 10A

frequency = 60 Hz

Calculate power throughout given x(t) and y(t) are assumed to be voltage waveform and current waveform

y(t)  = 10cos(120πt)

frequency of x(t) = 100 Hz

frequency of y(t) = 60 Hz

power = IV   where frequency is constant/similar

B. a model

Explanation:

A three-dimensional rendering of a product concept is called a model.

An example of a model used in computer programming is the software development life cycle (SDLC) model.

Software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications.

Some of the models used in the software development life cycle (SDLC) are;

I. A waterfall model: it can be defined as a process which involves sequentially breaking the software development into linear phases. Thus, the development phase takes a downward flow like a waterfall and as such each phase must be completed before starting another without any overlap in the process.

II. An incremental model: it refers to the process in which the requirements or criteria of the software development is divided into many standalone modules until the program is completed.

III. A spiral model: it can be defined as an evolutionary SDLC that is risk-driven in nature and typically comprises of both an iterative and a waterfall model. Spiral model of SDLC consist of these phases; planning, risk analysis, engineering and evaluation.

He is correct as many engines are run by diesel. It produces more power as that is how cars produce more power.

In the United States, it should be noted that a bicyclist is killed every six hours.

The cause of the accidents has been attributed to the rough driving of vehicle drivers and some faults are on the part of the cyclist as well.

Rapidly overtaking a bicycle is dangerous. Also, there are some vehicle drivers who drive into the lanes that are meant for cyclists. This isn't appropriate.

Drivers should ensure that they are not close to the cyclists when driving as there should be a space of at least 3 feet between the bicycle and the vehicle.

Furthermore, when there is a narrow traffic lane, the vehicle drivers should ensure that there's a clear traffic in the opposite lane before they change their lanes.

Lastly, both the cyclists and the vehicle drivers should not overspeed and drive safely.

Based in the information given above, the correct option is D.

Answer:

a) it is periodic

N = (20/3)k = 20 { for K =3}

b) it is Non-Periodic.

N = ∞

c) x(n) is periodic

N = LCM ( 5, 20 )

Explanation:

We know that In Discrete time system, complex exponentials and sinusoidal signals are periodic only when ( 2π/w₀) ratio is a rational number.

then the period of the signal is given as

N = ( 2π/w₀)K

k is least integer for which N is also integer

Now, if x(n) = x1(n) + x2(n) and if x1(n) and x2(n) are periodic then x(n) will also be periodic; given N = LCM of N1 and N2

now

a) cos(2π(0.15)n)

w₀ = 2π(0.15)

Now, 2π/w₀ = 2π/2π(0.15) = 1/(0.15) = 1×20 / ( 0.15×20) = 20/3

so, it is periodic

N = (20/3)k = 20 { for K =3}

b) cos(2n);

w₀ = 2

Now, 2π/w₀ = 2π/2) = π

so, it is Non-Periodic.

N = ∞

c)  cos(π0.3n) + cos(π0.4n)

x(n) = x1(n) + x2(n)

x1(n) = cos(π0.3n)

x2(n) =  cos(π0.4n)

so

w₀ = π0.3

2π/w₀  = 2π/π0.3 = 2/0.3 = ( 2×10)/(0.3×10) = 20/3

∴ N1 = 20

AND

w₀ = π0.4

2π/w₀  = 2π/π0. = 2/0.4 = ( 2×10)/(0.4×10) = 20/4 = 5

∴ N² = 5

so, x(n) is periodic

N = LCM ( 5, 20 )

Answer:

a) the point at which the transistor enters the saturation region is 1.5 v

b) the value of ID is obtained in saturation is 1.125 mA

Explanation:

Given the data in the question;

for an NMOS, the condition for the saturation is;

V_DS ≥ V_GS - V_t

V_GS is 2.5 v and V_t is 1 v

so we substitute

V_DS ≥ 2.5 - 1

V_DS = 1.5 v

so the point at which the transistor enters the saturation region is 1.5 v

The drain current I_d in the saturation region;

I_d = 1/2×μₙ×Cₐₓ×W/L×( V_GS - V_t)²

= 1/2Kₙ (  V_GS - V_t)²

our Kₙ is 1 mA/V², V_GS is 2.5v and V_t is 1 v

so we substitute

I_d = 1/2(1 mA/V²)( 2.5 - 1 )²

= 1/2(1 mA/V²)( 2.25)

= 1.125 mA

therefore, the value of ID is obtained in saturation is 1.125 mA

Answer:

When analyzing forces in a structure or machine, it is conventional to classify forces as external forces;

constraint forces or internal forces.

External forces arise from interaction between the system of interest and its surroundings.

Examples of external forces include gravitational forces; lift or drag forces arising from wind loading;

electrostatic and electromagnetic forces; and buoyancy forces; among others. Force laws governing these

effects are listed later in this section.

Constraint forces are exerted by one part of a structure on another, through joints, connections or contacts

between components. Constraint forces are very complex, and will be discussed in detail in Section 8.

Internal forces are forces that act inside a solid part of a structure or component. For example, a stretched

rope has a tension force acting inside it, holding the rope together. Most solid objects contain very

complex distributions of internal force. These internal forces ultimately lead to structural failure, and also

cause the structure to deform. The purpose of calculating forces in a structure or component is usually to

deduce the internal forces, so as to be able to design stiff, lightweight and strong components. We will

not, unfortunately, be able to develop a full theory of internal forces in this course – a proper discussion

requires understanding of partial differential equations, as well as vector and tensor calculus. However, a

brief discussion of internal forces in slender members will be provided in Section 9.

Explanation:

The amplitude of the sinusoid is 28384 *x soít cos.

Amplitude is defined as the greatest deviation from equilibrium of a point on a vibrating body or wave in terms of displacement or distance traveled. In most cases, amplitude is calculated by looking at a wave graph and determining the height of the wave from rest. The strength or intensity of the wave is gauged by its amplitude.

Sinusoid is defined as a signal with sine wave characteristics. In the liver, spleen, and bone marrow, sinusoids and irregular tubules transport blood in place of venules and capillaries. The sine or cosine functions from trigonometry form the foundation of sinusoidal signals, which are periodic functions.

Thus the amplitude of the sinusoid is 28384 *x soít cos.

Answer:

1: the negative battery terminal

Explanation:

When we design and develop an electrical circuit in electrical and electronics engineering, it is important that we define a reference point for all electronic signals from which we can measure voltage. Although, the voltage passing through a reference point in an electrical circuit is typically 0 Volts.

Also, a ground is a common return path in an electrical circuit for the current flowing through the circuit.

When working on a direct current (DC) circuit that is mainly operated using a battery, the negative terminal of the battery would be the ground (reference point) for all the components connected to the electrical circuit.

Hence, in the context of electronics, the term "ground" is often used to refer to the negative battery terminal.
