How To Write An Effective Declaration Page For Your Thesis – Template

Published by Alvin Nicolas at March 13th, 2024 , Revised On April 5, 2024

A declaration page stands as a testament to the integrity and authenticity of a thesis. It is a succinct section at the beginning of the document and outlines key information and affirmations regarding the authorship and originality of the work. 

Essentially, it serves as a formal declaration of the author’s adherence to ethical standards and their acknowledgement of the contributions made towards the completion of the thesis. 

A declaration page acts as a cornerstone of academic integrity and helps reinforce the credibility of the research presented within the thesis or dissertation . 

By explicitly stating that the work is original and free from plagiarism, the author not only upholds the principles of honesty but also demonstrates their commitment to scholarly standards. 

Let’s explore this further. 

What Is A Thesis Declaration Page

The declaration page within a thesis serves as a foundational element, providing essential information and affirmations crucial for academic integrity. 

The declaration page, often positioned at the beginning of a thesis, is a formal section dedicated to asserting the authenticity, originality, and ethical adherence of the work presented within the document. It serves as a declaration of the author’s commitment to scholarly integrity and honesty.

This declaration is typically mandated by academic institutions as a requisite component of thesis submission, aimed at upholding rigorous standards of academic conduct.

Purpose Of A Dissertation Declaration

The primary purpose of the declaration page is twofold: to affirm the originality of the research and to acknowledge the contributions of individuals or sources that have assisted in the thesis’s completion. 

By formally declaring the work’s authenticity and adherence to ethical standards, the author establishes credibility and trustworthiness, essential qualities in academic discourse.

Moreover, the declaration page functions as a transparent record of the author’s involvement in the research process , delineating their contributions and attributions. 

It serves as a testament to the author’s accountability and responsibility for the content presented within the thesis, thus safeguarding against plagiarism and intellectual dishonesty.

Key Components To Include

Here are some of the key components to include in your declaration guide. 

Title Of The Thesis

The declaration page typically begins with the title of the thesis , serving as a concise identifier of the research topic or subject matter. The title should accurately reflect the scope and focus of the thesis, providing readers with a clear understanding of its contents.

Name Of The Author

Following the title, the declaration page includes the name of the author, affirming their authorship and responsibility for the research presented within the thesis.

The author’s name serves as a key identifier, linking them directly to the work and asserting their ownership of intellectual contributions.

Declaration Of Originality

Central to the declaration page is the declaration of originality, wherein the author asserts that the work presented within the thesis is their own original creation.

This declaration typically includes statements affirming that the research has not been plagiarised and that any sources or references utilised have been properly cited.

Statement Of Contributions

The statement of contributions provides an opportunity for the author to acknowledge the individuals or entities that have contributed to the completion of the thesis. This may include supervisors , advisors, collaborators, or funding agencies, among others. 

The statement should clearly delineate the specific contributions made by each party, highlighting their roles in the research process.

Acknowledgements (If Applicable)

In some cases, the declaration page may include a section for acknowledgements, wherein the author expresses gratitude to individuals or organisations who have provided support, guidance, or inspiration during the course of the research. 

Acknowledgements may include mentors, peers, family members, or institutions that have facilitated the author’s academic pursuits.

Date Of Submission

Finally, the declaration page concludes with the date of submission, indicating the date on which the thesis was formally submitted for evaluation or examination. 

The inclusion of the submission date serves as a record of the thesis’s completion and submission timeline, ensuring compliance with academic deadlines and requirements.

How To Write A Declaration Page

Creating a declaration page that is both impactful and professional requires attention to detail and adherence to certain principles. 

Clear & Concise Language

One of the cardinal rules of crafting an effective declaration page is to use clear and concise language. Avoid ambiguity or verbosity, and strive for clarity in expressing your affirmations and acknowledgements. 

The declaration should be easily understandable to readers, conveying your commitment to academic integrity without unnecessary embellishment.

Formatting & Presentation Tips

Formatting plays a crucial role in the presentation of the declaration page. Ensure that the page layout is clean and organised, with consistent font styles and sizes. 

Use headings and subheadings to delineate different sections of the declaration, making it easier for readers to navigate. Additionally, pay attention to spacing and alignment to maintain a polished appearance.

Honesty & Integrity

Honesty and integrity are paramount when crafting a declaration page. It is essential to uphold the highest ethical standards and truthfully affirm the originality of your work. 

Avoid any misleading statements or exaggerations, as they can undermine the credibility of your thesis. Demonstrating integrity in your declaration not only reflects positively on your character but also reinforces the trustworthiness of your research.

Institutional Guidelines & Requirements

Every academic institution may have its own specific guidelines and requirements for declaration pages. Before crafting your declaration, familiarise yourself with these guidelines to ensure compliance. 

Pay attention to formatting specifications, word limits, and any specific language or statements that may be required. Adhering to institutional guidelines demonstrates your attention to detail and respect for academic conventions.

Writing The Declaration Of Originality

The declaration of originality is a crucial component of the declaration page, affirming the authenticity and uniqueness of your work. 

What Constitutes Original Work

Original work refers to content that is created by the author and has not been previously published or plagiarised from other sources. When writing the declaration of originality, it is important to understand what constitutes original work within the context of your field of study. 

This may include original research findings, innovative ideas, or creative interpretations of existing knowledge.

Avoiding Plagiarism

Plagiarism is a serious offence in academia and must be strictly avoided. When writing the declaration of originality, explicitly state that the work presented in your thesis is your own and properly acknowledge any sources or references used. 

Take care to cite all sources accurately and follow citation conventions prescribed by your institution. By demonstrating a commitment to academic honesty, you uphold the integrity of your research.

Authorship Declaration

The Authorship Declaration is designed to assist researchers to comply with the  Australian Code for the Responsible Conduct of Research  (the Code), and to meet the requirements of the University of Adelaide’s  Authorship Policy  (the Policy).

An Authorship Declaration must be completed by the author of a publication, or where there are multiple authors, by the corresponding author. This needs to be done before the publication is presented in a public forum. This new online form replaces the existing paper-based version of the declaration.

Use the declaration

Creating an Authorship Declaration, or providing consent to be named on one, ensures you are receiving a fair allocation of credit towards a publication. The online form creates an effective mechanism to assist the corresponding author with obtaining permissions from other contributing authors, or to dispute or decline an authorship position.

By adhering to both the Code and the Policy, researchers are protecting themselves and the University against potential disputes, and ensuring the University is compliant with its governance responsibilities.

All researchers recorded on the Authorship Declaration are able to track progress of their forms and access any records of previously submitted declarations upon which they are listed.

If you have questions regarding the Authorship Declaration such as when you should complete the declaration or more information about the declaration itself which are not answered on the FAQ page, please reach out to a Research Integrity Adviser for further support. There are several advisors who can assist you with your queries.

If you are having technical issues with the functionality of the form itself ie. the form is not functioning, notifications are not going across etc., please raise a ticket with ITDS via your MyIT page  and outline what specific issue you are having with the form.

Here are some resources to assist with completing and submitting the form:

• Quick reference guide
• Introductory video  (MP4)
• Process map

Where can I find the Authorship Policy?

The Authorship Policy (the Policy) is located at  http://www.adelaide.edu.au/policies/3503 .

When should I prepare an Authorship Declaration

A Declaration can be initiated early (in ‘draft’) to document an agreement between parties (facilitated through the ‘approval’ stage) and reviewed throughout preparation of the publication. If you have separate agreements of expected involvement (e.g. on email) you can upload that as evidence of the historical discussion.

At any time that a contribution/contributor changes, a form that is in ‘approval’ can be moved back into draft and changes made. All parties would then be sent the Declaration again for approval of the changes and to support their continuing involvement. This can happen as often as it is needed, leaving the ‘finalise’ stage until the publication is ready. This is a good way to facilitate discussions and document contributions as a project evolves.

Approval should always be sought from contributors, and documented, prior to submission of a publication to a public forum.

Where can I access the Authorship Declaration

The Authorship Declaration (the Declaration) is located at  https://authorship.adelaide.edu.au .

Why do I need to complete the Authorship Declaration?

In compliance with the Australian Code for the Responsible Conduct of Research (the Code), and to meet the University of Adelaide's Authorship Policy (the Policy), an 'Authorship Declaration' must be completed by the author of a publication, or where there are multiple authors, by the corresponding author. This must be done before the publication is presented in a public forum.

The Authorship Declaration ensures all authors who have contributed to the research outcome have provided their 'written' consent, and have approved the version of a research publication to be published.

There are certain circumstances where this is not possible, such as where an author is deceased or cannot be contacted following reasonable efforts. In this instance (where 30 days have elapsed as per the Policy), the publication may proceed to publication provided that there are no grounds to believe that this person would have objected to being included as an author.

Seeking approval for the work is important. Remember, as per the Policy, " a publication may not proceed if any of the authors have legitimate reservations concerning the theory, data or its interpretation underpinning critical parts of the work ".

I am a HDR student, am I required to use the Authorship Declaration?

If the publication is going into your thesis, you are required to complete the ' Statement of Authorship ' as per the Adelaide Graduate Research School guidelines . You will also need to complete the electronic Authorship Declaration prior to publication, in accordance with the Policy.

If you are a corresponding author on a publication which is not going into your thesis, you will need to use the electronic Authorship Declaration prior to publication.

If you are listed as a co-author/acknowledgement for a non-thesis publication, you are also required to make your declaration using this electronic Authorship Declaration. The corresponding author will send you a request for your approval.

Who can create an Authorship Declaration?

A corresponding author can create an Authorship Declaration as they maintain ultimate responsibility for the publication. It is possible for others to initiate the Declaration, however they cannot request approval of others. The corresponding author must be a member of the University of Adelaide community.

Who Is the corresponding author?

As per the Policy, " in circumstances where there is more than one author, a corresponding author must be appointed to record authorship and manage communication about the work with the publisher.

In compliance with the Code, an 'Authorship Declaration' must be completed by the author of a publication or, where there are multiple authors, by the corresponding author. This must be done before the publication is presented in a public forum ".

Different disciplines may have different ways of appointing the corresponding author, so it is important to discuss, and agree to, authorship process early.

Who Is a contributing author (or co-author)?

A contributing author is an author who has provided a substantial contribution to at least two (2) of the following three (3) activities:

• conception and design of the project;
• analysis and interpretation of research data;
• drafting significant parts of the article or critically revising it so as to contribute to the interpretation

A contributor who has not met the above criteria should be referred to as an acknowledgement in accordance with the Policy.

Are honorary or 'token' authorships acceptable?

As per the Policy, " authorship must not be offered purely on the following grounds:

• holding a position of authority (e.g. head of a research group or a supervisory role);
• facilitating the acquisition of funding;
• providing routine assistance in some aspects of the project;
• providing a technical contribution, data that has already been published or materials obtained from third parties, but making no substantial input to the project or publication".

Is the Authorship Policy followed if the corresponding author is not a member of the University of Adelaide?

No, the policy of the corresponding author's institution is to be followed.

Can a corresponding author be changed once an Authorship Declaration has been created?

No, the corresponding author can only be updated by creating a Declaration with the new contributing author's details. Note: for the purposes of this Declaration, the corresponding author should be the corresponding author who will be listed on the publication once it reaches the public domain, and is the person who takes overall responsibility for the publication. Correspondence with a publisher in relation to publication should come after the author has sought approval from all authors to submit.

If the corresponding author leaves the University of Adelaide they will not be able to complete the University's Authorship Declaration, but they must follow the Authorship Policies of the institution to which they move. They must also continue to show the affiliation with the University of Adelaide, with respect to that research.

I am a corresponding author & completing an Authorship Declaration early in the project, I have not decided the publication title, to whom the publication will be submitted or when the publication will be submitted. What do I do?

These fields should be populated with the best estimate possible. The Declaration can be kept in draft until this information is finalised and the Declaration is ready to be submitted for approval to co-authors (these fields will then be locked).

What document(s) do I attach to the Authorship Declaration?

In accordance with Policy, authors are required to approve the version of the publication which is to be published. Therefore, the final version of the manuscript (or other publication) should be attached to the Declaration.

Communication which occurs outside of the system to seek authorship approval or resolve disputes can also be attached to the Declaration.

How many authors are required to be entered into the Authorship Declaration?

The first 20 authors are required to be added and all of the University of Adelaide authors. Each should be added on a separate row. Where there are more than 20 authors, a document showing the complete list of authors should be uploaded into the Authorship Declaration.

What is the difference between dispute and decline?

A dispute is a disagreement over authorship. The dispute may be in relation to the authors listed in the publication, the author order or the contribution(s) made by authors as per the authorship criteria.

Per the Authorship Policy, " if a dispute remains unresolved within 30 days of referral under clause 3.2, it will be referred to the Deputy Vice-Chancellor and Vice-President (Research) for determination. The DVC&VP(R) may engage an external arbitrator or mediator to assist in this process, although the final decision remains with the University ".

A decline relates to a decline of authorship, i.e. an author would like to be removed from the author listing of a publication.

As a corresponding author what do I do if a co-author has not responded to my Authorship Declaration?

Per the Authorship Policy, " a co-author has 30 days to offer authorship to all people, including research trainees, who meet the criteria for authorship listed in the Policy. Those offered authorship must accept or decline in writing within 30 days. If a potential author fails to respond in 30 days, the corresponding author must keep a record of decisions made on behalf of the authors ".

Can I save the Declaration without completing it?

Yes, the Declaration will auto-save while you work and there is also the option to 'Save and Exit'. This means you can keep the Declaration in draft while discussing the publication with co-authors.

I am a corresponding author & a co-author has left the University prior to an Authorship Declaration being finalised. How do i liaise with the co-author for the approval of authorship?

If the co-author's work was done during his/her tenure at the University of Adelaide, the co-author's affiliation on the Declaration should be listed as University of Adelaide. You are able to change the email address to one that is current in order to communicate with this author.

What am I required to do if my publication is declined by the journal/symposium and I wish to resubmit it elsewhere?

This would require locating the finalised Declaration (in the 'Create and Manage Declarations' tab) and using the 'Edit Authorship Declaration' button to make edits to the publication title (if needed) and the public forum to which it will be resubmitted.

Note: this assumes there are no changes required to the publication itself.

Once changes have been made to the Declaration you will need to re-submit the Declaration to co-authors for approval. The co-authors will receive a communication notifying them that there have been changes to the Declaration.

What am I required to do if my publication requires major changes?

This would require locating the finalised Declaration (in the 'Create and Manage Declarations' tab) and using the 'Edit Authorship Declaration' button to make any changes to the Declaration.

To ensure contributors are reviewing the final version of the publication to be submitted to the public forum, use the upload section of the Declaration to attach the final version of the publication.

Do I need to lodge the completed Authorship Declaration with the Head of School?

No, the electronic Authorship Declaration is maintained centrally and can be accessed by Heads of School if required.

Does the Authorship Declaration integrate with Aurora?

No, the Declaration does not integrate with Aurora at this stage.

Dissertation

Definition:

Dissertation is a lengthy and detailed academic document that presents the results of original research on a specific topic or question. It is usually required as a final project for a doctoral degree or a master’s degree.

Dissertation Meaning in Research

In Research , a dissertation refers to a substantial research project that students undertake in order to obtain an advanced degree such as a Ph.D. or a Master’s degree.

Dissertation typically involves the exploration of a particular research question or topic in-depth, and it requires students to conduct original research, analyze data, and present their findings in a scholarly manner. It is often the culmination of years of study and represents a significant contribution to the academic field.

Types of Dissertation

Types of Dissertation are as follows:

Empirical Dissertation

An empirical dissertation is a research study that uses primary data collected through surveys, experiments, or observations. It typically follows a quantitative research approach and uses statistical methods to analyze the data.

Non-Empirical Dissertation

A non-empirical dissertation is based on secondary sources, such as books, articles, and online resources. It typically follows a qualitative research approach and uses methods such as content analysis or discourse analysis.

Narrative Dissertation

A narrative dissertation is a personal account of the researcher’s experience or journey. It typically follows a qualitative research approach and uses methods such as interviews, focus groups, or ethnography.

Systematic Literature Review

A systematic literature review is a comprehensive analysis of existing research on a specific topic. It typically follows a qualitative research approach and uses methods such as meta-analysis or thematic analysis.

Case Study Dissertation

A case study dissertation is an in-depth analysis of a specific individual, group, or organization. It typically follows a qualitative research approach and uses methods such as interviews, observations, or document analysis.

Mixed-Methods Dissertation

A mixed-methods dissertation combines both quantitative and qualitative research approaches to gather and analyze data. It typically uses methods such as surveys, interviews, and focus groups, as well as statistical analysis.

How to Write a Dissertation

Here are some general steps to help guide you through the process of writing a dissertation:

• Choose a topic : Select a topic that you are passionate about and that is relevant to your field of study. It should be specific enough to allow for in-depth research but broad enough to be interesting and engaging.
• Conduct research : Conduct thorough research on your chosen topic, utilizing a variety of sources, including books, academic journals, and online databases. Take detailed notes and organize your information in a way that makes sense to you.
• Create an outline : Develop an outline that will serve as a roadmap for your dissertation. The outline should include the introduction, literature review, methodology, results, discussion, and conclusion.
• Write the introduction: The introduction should provide a brief overview of your topic, the research questions, and the significance of the study. It should also include a clear thesis statement that states your main argument.
• Write the literature review: The literature review should provide a comprehensive analysis of existing research on your topic. It should identify gaps in the research and explain how your study will fill those gaps.
• Write the methodology: The methodology section should explain the research methods you used to collect and analyze data. It should also include a discussion of any limitations or weaknesses in your approach.
• Write the results: The results section should present the findings of your research in a clear and organized manner. Use charts, graphs, and tables to help illustrate your data.
• Write the discussion: The discussion section should interpret your results and explain their significance. It should also address any limitations of the study and suggest areas for future research.
• Write the conclusion: The conclusion should summarize your main findings and restate your thesis statement. It should also provide recommendations for future research.

Ethical declarations that authors should provide at the journal submission stage

Ethical Declarations

Dr. Radhika N.S.

Ethical declarations in research form an integral part during the submission process of a manuscript to a journal. During the process of submission,  there are several questions and statements that you as the author need to respond to before submission. Let us look at all of these one-by-one.

Pre-submission considerations related to authorship

Before you submit your manuscript to the journal, you need to take into consideration some important aspects of authorship listed below:

• Ensure that all the authors mentioned in the manuscript have agreed for authorship, read and approved the manuscript, and given consent for submission and subsequent publication of the manuscript. (The authorship criteria should be based on the ICMJE guidelines .)
• The order of authorship must be agreed by all named authors prior to submission.
• Full names, institutional affiliations, highest degree obtained by the authors, e-mail address (in some cases, ORCiD ID and social media handles - Facebook, Twitter, or LinkedIn) need to be clearly mentioned on the title page.
• The corresponding author, who takes full ownership for all the communication related to the manuscript, should be designated and his/her detailed institutional affiliation (including the postal address, telephone number, fax number, and e-mail address) should be provided.
• Some journals ask for guarantors who may be the same as the corresponding author or a different person (a senior researcher in the group who oversees the progress of the research work). Depending on what your target journal expects of a guarantor, he/she may be responsible for the integrity of the manuscript (including ethics, data handling, reporting of results, and study conduct),  would communicate with the journal if any technical clarifications related to the manuscript are required, and would handle similar responsibilities.

All the authors need to agree on the name(s) included in the Acknowledgement section.

Manuscript submission related declarations : When submitting your manuscript to a journal, you need to follow the policies and guidelines of the journal. Most journals expect authors to declare the following:

• The manuscript in part or in full has not been submitted or published anywhere . In other words, the authors should ensure that the manuscript is not a duplicate publication .
• The manuscript will not be submitted elsewhere until the editorial process is completed.
• If any part of the manuscript contains previously published content (figures/tables), authors should submit a statement of permission to reproduce the material signed by the author(s) and publishers concerned.
• When submitting material related to commercial products, it may, in some circumstances, be appropriate for the author to forward a copy of the contribution to the manufacturers before publication. This is to verify the correctness of the contents of the section in the manuscript that describes the new device/product.
• Authors should declare any previous or pending publication of the manuscript’s content in any conference proceedings, letters to journals and brief communications, or as pre-prints on repositories like arXiv , biorXiv , Figshare , etc.
• Authors should ensure that if the current study’s Abstract has been published in any conferences, it is either not under a copyright or that the embargo period is over . If the Abstract is under copyright protection from the publishers, permission should be sought for re-using the material.
• In case the manuscript is a secondary publication i.e. it is a subsequent republication that will be published in two or more journals (in the same or another language), the authors should explicitly declare this. Moreover, they should obtain mutual consent of the journal editors and follow the stipulated guidelines .
• If the manuscript is based on a dataset that has been the basis of another manuscript, authors should maintain transparency in such cases. They should declare that by referencing previously published article in the manuscript.
• If there is a data set associated with the manuscript, provide information about where the data supporting the results or analyses presented in the paper can be accessed. Where applicable, this should include the hyperlink to publicly archived datasets, DOI, or other persistent identifier associated with the data set(s). Always check the journal’s guidelines for specific templates or style in which this information should be presented. While describing a new software tool/ application, authors should host their project with a recognized open-source repository such as http://www.bioinformatics.org/ or https://sourceforge.net/ . Information such as the project name, project home page, operating system(s), programming language, license, and any restrictions to use by non-academics should accompany the manuscript.

Statements of ethical approval for studies involving human subjects and/or animals

If your study involves human subjects and/or animals, and also if your manuscript includes case reports/case series, you need to provide the following:

• Authors must provide the name of the ethical approval committee/Institutional Review Board they have obtained consent from along with approval number/ID.
• Authors should specifically mention if a waiver was obtained for the study and reason for the waiver. They should confirm that the study was conducted in accordance with Helsinki Declaration as revised in 2013 .
• Authors must state that written informed consent was obtained from the participants of the study (and the relevant document(s) must be provided when requested by the journal). If verbal informed consent was obtained, the reason(s) for the absence of written consent must be provided.
• For case reports/case series involving minor subjects/children/infants, authors should confirm that the statements of written informed consent from legally authorized representatives/parents/guardians are available; if verbal informed consent was obtained, reasons for this must be mentioned.
• Since patients have a right to privacy , identifying information (including patients’ images, names, initials, or hospital numbers) should not be included in recordings, written descriptions, or photographs, unless the information is essential for scientific purposes. In any case, written informed consent from the patient must be obtained for publication of these graphics in print and electronic form. If such consent has not been obtained, personal details of patients in any part of the paper and in any supplementary materials (including illustrations) must be removed before submission.

Declarations specific to article types

We have looked at the declarations related to manuscript submission and when your study involves human or animal subjects. Let us now turn to specific article types and the declarations you need to prepare when submitting them.   

1. Clinical trials : Clinical trials that prospectively assign human participants to one or more health-related interventions to evaluate the effects on health outcomes (such as drugs, surgical procedures, devices, behavioural treatments, dietary interventions, and process-of-care changes) must conform to CONSORT guidelines. They must provide a confirmation that the guidelines have been followed, which should be submitted with their protocols.For randomized controlled trial, please state the International Standard Randomised Controlled Trial Number (ISRCTN) or the trial registry and trial registration number recognized by ICMJE or WHO ICTRP.  

If your clinical trial was not registered or if the registration is not applicable to your study, you must state the reason(s) as to why it was not done. Many journals accept retrospectively registered studies too. Hence, if you have not registered your study prior to starting the trial, you may do so mid-way or after completion of the study.

Since there are several different types of studies, please ensure that your research work conforms to the specific guidelines as specified in EQUATOR Network . For example, case reports must follow CARE Guidelines and observational studies must follow STROBE Guidelines . The respective checklists must be submitted along with the manuscript during submission.

2. Reviews : Reviews do not need any ethical approvals or informed consent. However, many journals do ask the authors to explicitly state the reason as to why they are not required for the sake of transparency. 

Other important declarations related to funding, conflicts of interest, and more

Apart from the declarations we have discussed, there are others that authors need to consider. Let us take a look at them:

1. Describing new taxa : Authors must provide relevant documents and unique digital identifier for manuscripts that describe new taxa or species. They should also declare that the relevant guidelines have been followed for algae, fungi and plants , zoological taxa , bacteria , and viruses . Registration numbers for the new species (for e.g. from MycoBank for fungi or ZooBank for zoological species) should be stated in the manuscript. New virus names should be sent to the relevant study groups for consideration before publication in a journal.

2. Authors’ contribution : The individual contributions of authors to the research work and writing of the manuscript should be specified in this section; for example, who conceived the study design, who did the data acquisition, who performed the experiments, who did the data analysis, who wrote the manuscript, etc. Authors should check journal-specific guidelines to declare the authors’ contribution.

3. Acknowledgments : Anyone who does not meet the authorship criteria, such as people who provided technical help, institutional/department head who provided general support, or medical writers who assisted with the preparation of the manuscript content, should be acknowledged. Even if the authors have no one to acknowledge, usually journals expect authors to include this section in the manuscript and write “Not applicable.”  

4. Funding : All sources of funding for the research work and their role (if at all) in the design of the study and collection, analysis, interpretation of data, and in writing the manuscript should be declared. Provide the name(s) of the funding agency/agencies along with the grant number(s). If the study did not receive any funding, report the same.

5. Competing interests/conflict of interest : All financial and non-financial competing interests must be declared by the authors. Non-financial competing interests include a declaration of political, personal, religious, ideological, academic, and intellectual competing interests. Authors from pharmaceutical companies, or other commercial organizations that sponsor clinical trials, should declare these as competing interests on submission. They should adhere to Good Publication Practice guidelines for pharmaceutical companies (GPP3) in medical publications.

Authors should declare any personal conflict of interest including any association with consultancies; employment details; participation in advocacy groups; stock or share ownership, and any financial details with regard to grants; fees; honoraria, reimbursements royalties, and any registered patents. They should also declare any institutional conflict of interest i.e. if their employer has any financial interest in or is in conflict with the subject matter or materials discussed in the manuscript. If there is no disclosure, add the following statement: “No potential conflict of interest was reported by the authors.”

Though the list is quite exhaustive, it is mandatory and important that the authors declare all the above-mentioned statements to avoid un-submission of the manuscript. These declarations ensure ethical publication practices involving transparency and integrity in the publication of the manuscript. Many journals have their own templates for declaring these and they are available on their author guidelines webpage. Authors should download these forms, fill them, sign, and upload them along with the manuscript during submission.

Bridged triarylamines, so-called N-heterotriangulenes (N-HTAs) are promising organic semiconductors for applications in optoelectronic devices. Thereby the electronic structure at organic/metal interfaces and within thin films as well as the electronically excited states dynamics after optical excitation is essential for the performance of organic-molecule-based devices. Here, we investigated the energy level alignment and the excited state dynamics of a N-HTA derivative adsorbed on Au(111) by means of energy- and time-resolved two-photon photoemission spectroscopy. We quantitatively determined the energetic positions of several occupied and unoccupied molecular (transport levels) and excitonic states (optical gap) in detail. A transport gap of 3.20 eV and an optical gap of 2.58 eV is determined, resulting in an exciton binding energy of 0.62 eV. With the first time-resolved investigation on a N-HTA compound we gained insights into the exciton dynamics and resolved processes on the femtosecond to picosecond timescale.

Optimized PID Controller for Atomizer Geometry: Artificial Intelligence Versus Traditional Methods

Oluwafemi Samuel Dada

Liberty University

This research compares two types of proportional-integral-derivative (PID) tuning methods, traditional and machine learning, to enable atomizer geometry modulation for effective breakup of non-Newtoni..

This research compares two types of proportional-integral-derivative (PID) tuning methods, traditional and machine learning, to enable atomizer geometry modulation for effective breakup of non-Newtonian slurry. Non-Newtonian slurries are not easily disintegrated due to their nature of having a high viscosity property that keeps changing during atomization. During effective atomization, consistent droplets are produced, and these are useful in many applications such as rocket propulsion where the breakup of gel propellant leads to better combustion that causes efficient propulsion. A baseline PID controller aims to enable the adequate adjustment of the atomizer nozzle diameter to compensate for steam pressure drop during atomization, leading to the production of consistent droplets. Steam is the heating gas that facilitates slurry breakup. We tested the baseline PID controller with transonic airblast nozzle model in Computational Fluid Dynamics (CFD) to compare the proposed machine learning algorithm with other PID tuning methods. The fuzzy logic, artificial neural network (ANN) and Zeigler Nichols (ZN) tuning methods were examined to determine the best method for the transonic airblast nozzle model. Results showed that the ANN method optimized the PID controller best. Identifying the PID performance with the ANN method is useful for industrial applications where PID controllers are greatly used.
