Thesis: a reflexive process

Research implies a continious scrutiny:

Research implies continious introspection: What is:

• My motivation
• My main goal
• The novelty of my idea
• The work that’s most related with mine, specially that of my competitor What is my hypothesis What are my evidences At which stage I am.

The technique/System/parameter X is better, for the task

Y , than each of its rivals Z , in dimension W.

Describes a new technique. Investigates an existing technique to discover:

• New properties.
• Relations between technique and others. Improves an existing technique. Applies an existing technique. Combines existing techniques.

Research in Science and Engineering

1.1 The exploration of a space of

techniques

The technique/ system/ parameter X is better for task

Y, than each of its rivals Z, in dimension W.

• Scientific
• Engineering.
• Behavioural (cognitive science).

Engineering Research

1.2. Establish properties with respect to

a dimension

The dimensions vary depending on the specific

nature of the research:

Efficiency (resources consumed by technique)

2.1 Scientific dimensions

• Run time and space.
• Statistical evidence: o Average, variance, better case, worst case, etc. Behaviour (result of technique)
• Correct, optimal, etc.
• Need external “gold standard”. Coverage (range of application)
• Completeness vs parcial.

2.2 Engineering Dimensions

Usability. Dependability. Maintainability. Scalability. Compatibility. Fitness.

2.4 The Unknown Dimension

Other dimensions, more subjective, with which we can compare two or more techniques are:

• Clarity.
• Parsimony, eg Occam’s razor.
• Prescriptability.
• Predictability.
• Simplicity, etc.

2.5 The impact of hypothesis on a

scientific text

§ A hypothesis that is:

Ambiguous Provokes doubt, uncertainty, or confusion in the reader (referee). Vague Provokes skepticism in the reader (referee) about the research methodology:

• There is no evidence, or it is not conclusive.
• Reasearch is not significant.

Content

1. Hypothesis and evidence.

2. Dimensions, guides to characterise research in engineering.

3. Types of research:

• theoretical vs. Experiment, and their implications.

4. Criteria for assessing research in Science and Engineering.

3. Types of research

The object of study can be found at different levels, for example: a

task, a system, a technique, a parameter, etc.

Research can be: theorical or experimental.
