The primary purpose of conducting a literature review is to gain a comprehensive understanding of the existing research in a particular field. This helps researchers identify gaps in the current knowledge, develop new research questions, and evaluate the feasibility of their proposed research projects.

Online forums are not typically considered a reliable source of information for a literature review, as they may contain inaccurate or biased information. Academic journals, conference proceedings, and government reports are more reliable sources of information, as they undergo a rigorous peer-review process.

Identifying gaps in the current knowledge is a crucial step in a literature review, as it helps researchers identify areas where further research is needed. This allows researchers to focus their efforts on addressing these gaps and contributing new knowledge to the field.

Conducting a meta-analysis is not typically used as a method for identifying gaps in the current knowledge during a literature review. Meta-analysis is a statistical technique used to combine the results of multiple studies to obtain an overall estimate of the effect of a particular intervention or treatment.

Developing clear and specific research questions is crucial in engineering research, as it ensures that the research is focused and manageable, facilitates the design of effective research methods, and allows researchers to communicate their research objectives clearly to stakeholders.

Prescriptive questions are not typically used in engineering research, as they aim to provide solutions or recommendations rather than generate new knowledge. Descriptive, comparative, and evaluative questions are more common types of research questions in engineering research.

Problem identification in engineering research involves identifying the root causes of a problem, developing strategies to address the problem, and evaluating the effectiveness of potential solutions. It is a crucial step in the research process, as it allows researchers to focus their efforts on solving real-world problems.

Literature review is not typically used as a method for problem identification in engineering research, as its primary purpose is to gain knowledge about the existing research in a particular field. Brainstorming, root cause analysis, and stakeholder analysis are more common methods for identifying problems in engineering research.

Considering ethical implications in engineering research is crucial to ensure that the research is conducted in a responsible and ethical manner, protect the rights and welfare of human subjects and animals involved in the research, and comply with regulatory requirements and guidelines.

Intellectual property rights are not typically considered an ethical issue in engineering research, as they relate to the legal protection of inventions and creative works. Informed consent, confidentiality, and animal welfare are more common ethical considerations in engineering research.

A research proposal in engineering research serves to outline the research objectives and methodology, justify the significance and feasibility of the proposed research, and request funding or support for the research project.

Research methodology is not typically included as a section in a research proposal, as it is usually discussed in detail in the main body of the proposal. The abstract, introduction, and literature review are more common sections in a research proposal.

Effective communication in engineering research is crucial to disseminate research findings to the scientific community, facilitate collaboration and knowledge sharing among researchers, and inform stakeholders and policymakers about the implications of the research.

Social media is not typically used as a primary method for communicating research findings in engineering research, as it is not considered a reliable or scholarly platform for disseminating research results. Academic journals, conference presentations, and technical reports are more common methods for communicating research findings in engineering research.

Peer review in engineering research serves to ensure the quality and validity of research findings, provide feedback and suggestions for improving the research, and identify potential ethical issues or concerns.
