Dear Sir or Madam,
I am seeking professional assistance in writing a scientific article focused on the phenomenon of cybersickness in virtual reality (VR) environments. The article should adhere to a strict 6-page limit, including references, and is intended for submission to an upcoming conference. Below, I outline the desired structure and specific elements to be included in the manuscriipt.
Objective:
The paper aims to explore cybersickness and its under-researched contributing factors such as stress, cognitive load, and movement (body and head movements). This investigation is motivated by observations from our VR training programs for law enforcement, which suggest higher instances of cybersickness than previously reported in literature.
Structure and Content:
My abstract (keep exactly this one):
This survey focuses on a crucial issue in virtual reality (VR) – cybersickness. Cybersickness is similar to motion sickness, but occurs with electronic screens or VR displays, as opposed to actual movement. Cybersickness refers to a cluster of symptoms, including nausea, eye strain, vertigo and sweating, to name a few. Some studies have reported that roughly 40% of the population may suffer from cybersickness. In our projects, we are interested in using VR for training of law enforcement officers, thus the scenarios are often stressful, involve several head movements (e.g., during surveillance) and often fast-moving scenes (e.g., car chases). We have observed over the years that our cybersickness statistics are usually higher than those reported in the literature. In this survey, we explore the literature to see if there have been any reported links between stress, cognitive load, and head and body movement to cybersickness levels. A total of xx papers were surveyed. Findings were often mixed and inconclusive, but pointed towards a positive relationship between cybersickness and both cognitive load and stress. Studies looking at head movements, on the other hand, showed a negative relationship with levels of cybersickness. It is hoped that these insights may help VR researchers develop new training protocols that can be more comfortable for users.
Introduction (1 page):
Introduce the concept of cybersickness, defining it and distinguishing it from traditional motion sickness. (Don’t forget to put references when you state something.)
Talk about factors hindering cybersickness (see PDF in attachment for example)
Highlight the relevance of studying stress, cognitive load, and physical movements (head and body) as potential contributors to cybersickness, emphasizing the novelty and necessity of this investigation (in line with our futur project with law enforcement).
Literature Review (Sections 2-4, approx. 3 pages):
Each section should focus on one of the three factors (stress, cognitive load, movements) and review existing literature, incorporating findings from the provided Excel file of scientific articles. you will also have to find new ones. Specifically:
Section 2: Impact of Stress on Cybersickness
Section 3: Impact of Cognitive Load on Cybersickness
Section 4: Impact of Movements on Cybersickness
Moreover, include analyses from the following papers, ensuring they are integrated into the respective sections:
Link to paper on Frontiers : https://www.frontiersin.org/articles/10.3389/frvir.2022.943409/full
Link to paper on IEEE Xplore : https://ieeexplore.ieee.org/abstract/document/9419213
Please ensure the article focuses on how the identified factors, such as stress, cognitive load, and physical movements, impact the onset of cybersickness, rather than the reverse scenario where, for example, cybersickness induces responses like stress in individuals. Additionally, it would be beneficial to include a table in each section summarizing the key findings, similar to the format utilized in the provided Excel file, to clearly present the data and analyses.
Discussion (1 page):
Discuss the implications of the literature findings in the context of VR training for law enforcement, including stress-inducing scenarios, surveillance activities, and dynamic scenes like car chases. Propose recommendations for future VR training protocols that could mitigate cybersickness, based on our project’s objectives and observations.
Conclusion (0.5 pages):
Summarize the key insights and their potential impact on developing more effective and comfortable VR training programs for law enforcement officers.
References (0.5 pages):
List all cited works, ensuring adherence to the conference’s formatting guidelines.

Hello , all the instructer of project is in attchmant and pleae let me know if project need more pages

Read the following:
Reliability Engineering/ERAU Hunt Library – O’Reilly
Chapter 2 (Sections 2.2), Hazard Rate
An idealized (though rarely occurring) shape of the hazard rate of a product is the bathtub curve. The bathtub curve is a model for system reliability, including early life burn-in and eventual wear-out at the system’s end of life.
The ‘bathtub’ refers to the shape of a line that curves up at both ends, similar in shape to a bathtub. The bathtub curve has 3 regions:
The first region has a decreasing failure rate due to early failures.
The middle region is a constant failure rate due to random failures.
The last region is an increasing failure rate due to wear-out failures.
Considering the above diagrams and considering the piecewise linear bathtub hazard function defined over the three regions of interest given below. The constants in the expressions are determined to satisfy the normal requirements for h(t) to be a hazard function.
Address the following questions in this discussion:
Briefly describe each region of the bathtub curve.
Develop the equations for the reliability function and the probability density function for the time to failure random variable based on the above hazard function.
How does the bathtub curve concept, which encompasses phases of early failures, random failures, and wear-out failures, relate to and impact the reliability of a system? Additionally, demonstrate your understanding by applying statistical techniques to model system reliability based on the given hazard function.

the characteristics of the more commonly used alternatives.
II. Grading
• Term paper will be graded out of 100 and weighs 10% in your final grade.
• The paper should include the following components:
1. Title and Abstract – (summary is written after the work on the paper is completed) – 0.5 page (10
points)

1. Prepare a PowerPoint presentation with 3 sections as per the following requirements:
a) Summarize ALL of the various types of rotary drilling rigs discussed in Chapter 4 of the
textbook. Do some online searching and include pictures of each type of rig in your
presentation.
b) Create ONE rig profile for a land, barge, jackup, submersible, semisubmersible, or drillship
type drilling rig (just one rig profile is needed for this assignment, NOT one for every rig type).
At a minimum, the rig profile should include a rig photo, the rig specifications, and the
company that owns the rig. Keep in mind that minimum effort results in earning a minimum
grade of a “C” on this assignment. Examples of rig profiles can be found on the drilling rig
contractor websites.
c) Create a list of services that might be contracted by the operator to drill a well using the rig in
your rig profile.
The following writing aids are located in the top block of Canvas to help the student with the
spelling and use of oil and gas industry terms, and to assist students in designing PowerPoint
presentations:

I am not requiring a minimum number of slides for the PPT. However, how well you cover the
required reading material will be considered in your assignment grade. Always remember that more
pages are not necessarily better when creating PPT presentations. Use the link in the Module 2

This assignment pertains to a course on leading and managing engineering teams. To complete it, carefully read the provided article and adhere to the outlined instructions. The case consists of five questions, requiring familiarity with the leadership dynamics specific to engineering teams. You must solve all questions with even the extra points.
Here’s a summary of what needs to be done for each question:
Redraw Fig. 2.2. for Two Teams: Requires creating a graph for the “Efficient Team” and the “Productive Group” based on the Kohler effect and hypothesizing trends. A brief explanation of the model and reasons for the differences between the teams is needed.
