Question Bank Topic 1 with Solutions – Net Value Functions Question Bank #1 – Net Value Functions: L03 – Engineering Economics & Net Value Applications Review Questions Recall the nanoRIMS example discussed in lecture. If the net value of buying the nanoparticles is $0 (the reference), determine the net value per week of having a grad student make the nanoparticles based on the following information: Benefit = $896/week Cost = Cost of consumable supplies per week Ingredients
...1. Functions of I/O Interface and Its Need
Functions of I/O Interface:
Synchronizes the speed difference between CPU and I/O devices.
Selects and addresses the appropriate I/O device for communication.
Provides control and timing signals for data transfer.
Buffers data during transfer, managing data flow between CPU and devices.
Converts data formats (e.g., serial to parallel, digital to analog and vice versa).
Detects and reports errors during data transfer.
Handles interrupts to inform CPU when
Sure! Here's a detailed explanation for each of your questions:
Software Engineering is called a layered technology because it is built on a foundation with multiple layers, each supporting the one above it. The layers are:
Quality Focus (Foundation Layer):
Process Layer:
TRH (hypothalamus) → stimulates TSH (anterior pituitary) → stimulates T3/T4 release (thyroid)
T3 = active, T4 = prohormone
Feedback loop: T3/T4 inhibit TRH + TSH
T3/T4 actions:
↑ Metabolic rate, HR, cardiac output
↑ Oxygen use, lipolysis, glucose metabolism
CNS effects (mood), reproductive effects
Iodide uptake → oxidation to iodine → binds to thyroglobulin
1. Shape Memory Alloys (SMAs)
Definition
Shape Memory Alloys R metallic materials that can recover their original shape after deformation when exposed 2 a specific stimulus, usually heat.
The most common example is Nickel-Titanium (Nitinol), known 4 its shape memory & superelastic behavior.
Mechanism
a. Phase Transformation
SMAs operate through a solid-state transformation between 2 phases:
Q. Briefly explain nitrogen cycle with diagram.
Ans:- The nitrogen cycle is a biogeochemical process where nitrogen, is converted between different chemical forms as it moves through the living and non-living organisms. It plays a crucial role in maintaining the nitrogen balance in ecosystems.
Stages of the Nitrogen Cycle
The nitrogen cycle consists of several important steps:
1. Nitrogen Fixation
2. Nitrification
3. Assimilation
4. Ammonification (Decay)
5. Denitrification
1. Nitrogen...
Explain array implementation of list. 5 marks
An array implementation of a list involves using a contiguous block of memory to store elements, allowing for efficient access and manipulation. Here’s a breakdown of the key aspects of this implementation:
1.) Structure:
°An array is a fixed-size data structure that holds elements of the same type. In the context of a list, an array can be used to store the list elements in sequential memory locations.
°The size of the array is typically defined
Define ADT. Explain array as an ADT? (2+3 marks)
An Abstract Data Type (ADT) is a conceptual model that defines a set of operations and behaviors for a data structure, without specifying the underlying implementation details. Arrays, as an ADT, define how data is organized and accessed through indices, but not how it's actually stored in memory.
Arrays as an ADT
-An array ADT defines a collection of elements that can be accessed by their index (position).
-Common operations on an array ADT
Nutrition: Nutrition is the biochemical and physiological processes by which an organism uses food support its life.
Health: Health is a state of complete physical, mental and social well being and absence of disease.
Type of Health:
1. Physical Health 2. Social Health 3. Spiritual Health 4. Emotional Health
1. Physical Health: It is define as the state in which every cell and every organ is functioning at optimum capicity and imperfect hormony will the rest of the body. The physical
