Confirmation Reports >> Abstracts
The Abstract is a self-contained piece of writing and usually appears in the front matter or preliminaries. The Abstract consists of summary statements for most or all sections in a confirmation report and hence is self-contained. Examiners and other readers often read the Abstract first so as to obtain the whole picture of a study, and then read the main body, which usually comprises Introduction, Literature Review, Methods, Preliminary Results, and Significance and Implications.
The main purpose of the Abstract is to offer readers an overview of the study and therefore help them form the first impression and make preliminary judgements on the significance of the study. The Abstract helps the readers form expectations of the contents in the confirmation report by summarising most or all sections in the confirmation report.
The Abstract is the standalone summary of an entire confirmation report, reflecting the essence of the study. The inclusion of summary statements about results, discussion, and conclusion depends on the progress of the study at the time the confirmation report is submitted. Some studies may have preliminary results while some may be at the stage of finalising the research design. For studies in the latter stage, students should make extra efforts in elaborating the feasibility of the study and projecting the expected results. The Abstract usually does not contain any references or footnotes.
Upon the submission of a confirmation report to the examination panel, the Abstract is probably the first part to be read. A well-written Abstract, which summarises the confirmation report succinctly and logically, can help impress the examiners. With an overall picture of the study in mind, the examiners can more easily comprehend the main text and follow the flow of ideas in the confirmation report.
The Abstract in a confirmation report needs to conform to the university and departmental requirements in terms of length, style, and layout (if any). Requirements often vary among universities and departments and students should refer to the guides issued by the university and the department. For clarification about the requirements, students should consult with their supervisors.

The Abstract in a confirmation report comprises six possible moves. They are:
- Research Topic;
- Research Background;
- Research Purpose;
- Methods;
- Preliminary Results; and
- Significance and Implications.
The six potential moves in their typical order in an Abstract are shown as follows.
MOVE 1 Research Topic
An Abstract may begin with a statement of the research topic, informing the readers of what the confirmation report concerns in a straightforward manner.
MOVE 2 Research Background
Providing background information helps readers identify the context and importance of the work. The Research Background move contains a specific problem statement of the research under consideration, listing the major existing solutions and their drawbacks. Defining the problem statement helps pave the way to establishing the research purpose.
MOVE 3 Research Purpose
A clear statement about the research purpose helps define and frame the scope of the work. An Abstract may begin with the research purpose instead of the research area.
MOVE 4 Methods (How was the research designed and conducted?)
A brief description of methods employed in the study informs readers of what was done and how the work was undertaken. The Methods move consists of descriptions of proposed algorithms, models, or experimental procedures. If the study is still in the planning stage, the Methods move may appear as summary statements about the proposed methods or models.
MOVE 5 Preliminary Results
The scientific quality of the study is shown by a brief overview of the preliminary results. The most important information from the preliminary results should be succinctly proclaimed within the word limit (if applicable) of an Abstract. The Preliminary Results move consists of statements that summarise experimental or simulation results obtained from data and observations made during experiments. If the experiments are to be performed, the Preliminary Results move may appear as statements about the predicted results.
MOVE 6 Significance and Implications
An Abstract usually ends with a positive note that explicitly states how the research may move the field forward or in what ways other researchers may make use of the final results to conduct further studies, leaving a good impression on readers. As the research work is still in progress at the time the confirmation report is written, the Significance and Implications move often appears as expected significance and implications of the study.
The length of a move often differs among Abstracts, from half a page to more than one pages; and those of different moves in an Abstract also vary. A move can be stretched across several sentences or even paragraphs while a sentence, in particular a complex sentence with subordinated clauses, can contain more than one moves.
These six moves may appear in a different sequence. It is possible that a move is absent from an Abstract. Similarly, some moves can be repeated cyclically. The following table shows two possible ways to organise the moves with explanatory notes.
Possible Ways to Organise the Moves |
Explanatory Notes |
Structure A |
The author writes the Research Background as the initial move and then narrows down the focus to the Research Topic. |
Structure B |
A move may repeat itself for several times in an Abstract. Structure B shows that the author states the Research Topic, Research Background, and Research Purpose at the outset, then describes the first Methods and their Preliminary Results, followed by the second Methods and their Preliminary Results. One of the possible reasons for having repeated moves is to align with the overall structure of a confirmation report, making the Abstract its exact microcosm. |

Extracts |
1. Research Purpose |
This project aims to analyse the effect of hydrogen addition on liquefied petroleum gas (LPG) inverse diffusion flame (IDF). NOTE 1 |
2. Research Topic |
IDF has drawn attention of researchers these years due to its features on safe operation, adjustable flame length and low soot emission. NOTE 2 |
3. Research Background |
An IDF, fuel and air are delivered separately so that the flame is more stable, and the operation is safer than that of Bunsen burner. NOTE 3 […] Fuel, which is not fully mixed with inner air jet, reacts with surrounding air to form a diffusion zone. With the special structure, an inverse diffusion flame shows distinctive features. NOTE 4 Hydrogen is a well-known clean fuel. With the lowest molecular weight, hydrogen has a very high burning velocity. The flammability range of hydrogen is also wide. NOTE 5 However, some problems exist in burning hydrogen. Hydrogen can easily catch fire. The combustion process should be carefully controlled to prevent accidents. NOTE 6 It can be seen that to realize using pure hydrogen in large scale is still in need of further research. NOTE 7 |
4. Methods |
To overcome the drawback of pure hydrogen and adopt the advantage of hydrogen, it may be a practicable way to mix hydrogen with other hydrogen carbon fuels, such as LPG. NOTE 8 With large molecular and high density, LPG may slow down the leaking speed of hydrogen and reduce hazard possibility. While addition of hydrogen may extend flame stability range of mixtures and may improve the heating performance of the flame. NOTE 9 This is an experiment-based project. Most data will be obtained through tests and experiments. NOTE 10 The experiments focus on […] impinging flame pollution emission of hydrogen enriched LPG inverse diffusion flame. In the experiment, the major variables include […]. Reynolds numbers of centre air jet are various from 500~7000 […]. Range of overall equivalence ration is from 0.5~2.2. NOTE 11 |
5. Preliminary Results |
Preliminary results show that small amount hydrogen addition can significantly extend stability range of LPG inverse diffusion flames. NOTE 12 The heights of LPG inverse diffusion flames under fixed Reynolds number are gradually lengthened with the equivalence ratio. […] And LPG IDFs are seen to be higher than H2-LPG IDFs in fuel-rich situations. NOTE 13 |

Extract D
This report proposes two different approaches to predicting the subcellular localization of proteins.
Extract F
The results demonstrate that the performance of GO methods is comparable to profile-alignment methods and outperforms those based on amino-acid compositions. Also, the fusion of these two methods can outperform individual methods.
Extract C
The second approach uses the accession number (AN) of a query protein and the accession numbers of homologous proteins returned from PSI-BLAST as the query strings to search against the Gene Ontology Annotation (GOA) database. The occurrences of a set of predefined GO terms are used to construct the GO vectors for classification by SVMs. Again, different approaches to constructing GO vectors were investigated.
Extract A
The first approach uses profile alignment scores and the occurrences of some predefined Gene Ontology (GO) terms as features and uses support vector machines (SVMs) as classifiers. The scores from the profile-alignment SVM and the GO SVM are fused to enhance classification performance. To make the best use of the GO terms, different approaches to constructing GO vectors from the GO terms returned from InterProScan were investigated.
Extract B
Experimental results based on a recent benchmark dataset suggest that using the accession numbers of homologous proteins as the query strings can achieve an accuracy of 93.97%, which is significantly higher than all published results based on the same dataset. The accuracy can be further increased to 98.89% if the accession numbers of the query proteins are also used as query strings.
Extract E
Computational methods are required to replace the laborious and time-consuming experimental processes for fast and reliable prediction in proteomics research.
- Extract E
The sentence provides further information about “protein subcellular localization” mentioned in the previous move, which requires “computational methods”.
- Extract D
The sentence describes the purpose of the study, which concerns the proposals of two prediction approaches.
- Extract A
The extract begins with the phrase “the first approach”, which refers to one of the two prediction approaches mentioned in the Research Purpose move. The extract introduces the key term “Gene Ontology (GO)” and describes the main parameters in the research method.
- Extract F
The beginning phrase “the results demonstrate” explicitly indicates the Preliminaries Result move. The preliminary results concern the “GO methods”, which is introduced in the preceding Methods move.
- Extract C
The extract begins with the phrase “the second approach”, which refers to one of the two prediction approaches mentioned in the Research Purpose move. The extract introduces the key term “accession number (AN)” and summarises the method.
- Extract B
The beginning clause “experimental results… suggest” clearly indicates the Preliminaries Result move. The phrase “accession numbers” refers to the “second approach” in the preceding Methods move.

The time division duplex (TDD) is a widely-recognised solution in wireless communication and two well-known examples of TDD systems are DECT and BluetoothTM. |
|
The study focuses on TDD switching circuits, which are crucial parts in the TDD systems. |
|
With a λ/4 transmission line that limits the bandwidth, PIN diodes are often used as the switching element in front-end RF switches. A two-stage configuration is necessary for PIN diodes to function over a dual band, which increases the board space of the diodes switch. |

|
In the study, the Si BJT transistor was used to build a power amplifier and a low-noise amplifier. A TDD switch was created by connecting a PA output directly to an LNA input. |
|
*a missing move |
|
Unlike the traditional pin-diode, the TDD switch does not need pin-diodes and a λ/4 transmission line. Because of this, the TDD switch can be produced at a low cost and is also small and inherently wide-band. |

The combustion process of an inverse diffusion flame (IDF), which 1) is characterised by its safe operation, adjustable flame length and low soot emission, 2) has been receiving considerable attention among researchers. With the lowest molecular weight, a very high burning velocity and a wide flammability range, hydrogen 3) is a widely-used clean fuel but 4) has a proneness to fire in combustion. To address the combustion problem, mixing hydrogen with other hydrogen carbon fuels, such as liquefied petroleum gas (LPG), may be a feasible solution. This experiment-based study probes into the effect of hydrogen addition on LPG IDFs. The hydrogen-enriched LPG IDF 5) was analysed in terms of its structure, length, impinging flame temperature distribution and pollution emission. The Reynolds number of centre air jet, overall equivalence, and hydrogen addition fraction 6) were employed as major variables to investigate the combustion process. Preliminary results reveal that the addition of a small amount of hydrogen markedly 7) widened the stability range of an LPG IDF. Given a constant Reynolds number, the heights of both LGP IDFs and 50% hydrogen diluted LGP IDFs 8) increased with the equivalence ratio. |
