Scientific writing: expressing the objectives of theses and dissertations using the approach of research questions and hypotheses

Syllabus


Objectives represent the heart of scientific writing. All other elements of the essay rely on them. Defining the objective(s) of a dissertation or thesis may seem like atrivial task for master’s and doctoral students. Many view it as merely a formality with little practical significance. This sense of triviality persists until the writing begins,at which point authors often lose the thread and get discouraged. Even worse, evaluators notice a disconnect between the objectives and the conclusions in the finalstages. Even if the wording is amended, this flaw can usually diminish the quality of the work or, at the very least, lessen its appreciation. Therefore, establishing theobjectives of a dissertation or thesis should be approached more objectively during the planning stage (but it is never too late for re-evaluation).
In this short course, the concepts, meanings, and methods of defining objectives in a scientific essay will be discussed from the tutor’s perspective and experience.The focus will be on the approach of research questions and hypotheses, which is not very common in Brazilian academia. The alignment of the objectives with theconclusion, as well as their interdependence with the introduction and discussion of the results, will be demonstrated (reaffirming an analogy of the objectives with aheart, now including their reciprocal dependence on other organs). Practical exercises will be carried out with the participants.
It is hoped that, by the end of this short two class-hour course, participants will be able to think more critically about the role of objectives in scientific writing,particularly in a dissertation or thesis. They should also be able to apply these concepts to develop and articulate the objectives of their work, starting from the proposalstage and especially during the actual writing of the dissertation or thesis.

Towards Zero-Emission Air Transport

Abstract


Global efforts toward decarbonization have highlighted the importance of addressing emissions in the transportation sector. For ground transportation, this has triggered an imminent transition towards multiple variants of electric vehicles. This talk will focus on air transportation. We will present the IZEA concept – an ongoing effort towards zero emission aviation – which relies on hydrogen as an alternative fuel for turbines and fuel cells. The talk will cover an overview of the proposed power train with emphasis on thermal management of its components (motors, power electronics, HTS cables, among others). The talk will conclude with a summary of ongoing efforts aiming to increase the overall aircraft cooling capacity and illustrating how that increased capacity can enable NOx reduction by supporting an expanded use of direct electrochemical conversion in fuel cells over combustion in hydrogen turbines.

Integrated Energy Systems for Sustainable Future

Abstract


Machine learning and Artificial Intelligence are rapidly evolving and are increasingly being used for developing dynamic models and for analysis and diagnostics. However, these data-based models are often not robust and generalizable, and do not capture many observed phenomena. On the other hand, nonlinear dynamics is able to satisfactorily explain many complex phenomena we can document in the physical world. We will explore how these physics-derived insights can help improve data-based models and especially assist diagnostics. Engineering and biomedical applications will be provided to discuss the promising synthesis of nonlinear dynamics and machine learning.

Hierarchical Flow Architectures in Heat Transfer

Abstract


Flow systems in nature, whether animate or inanimate, have evolved in time toward greater efficiency by adapting, or ‘morphing’, their configuration to decrease resistance to the currents flowing through them. Observations at various scales indicate that the distribution of flow, i.e. the connection of a point to a volume or vice-versa, is the most efficient when it occurs through a dendritic architecture. Heat flow channels function in concert with the structures around them, as a combination of long and fast heat flows along the channels, with short and slow heat flows through the surrounding medium. Our previous work theorized the deterministic nature of morphing and showed how to obtain efficient flow configurations for combined and sometimes competing objectives.


In this talk, we will discuss first how to reach quasi-isothermal compression and expansion through the inclusion of phase change materials (PCM) elements within the compression chamber of liquid pistons. The importance of giving configuration to the PCM inclusions will be covered. Next, we will consider the design of capillary networks for the cooling of high-power electronic components. While the mechanisms are complex and involve several drivers, we will show how to obtain a conceptual understanding of how all the channels morph to allow enough capillary pressure in each branch and minimum friction losses to pull the maximum flow rate out of the system for evaporation heat transfer. Thirdly, we will present an application related to the thermal management of EV batteries in which hierarchical flow architectures are the main features of the liquid cooling solution. This example will shed light on the possibilities opened by passive thermal management as a way to provide more sustainable solutions.
Throughout the talk, we will emphasize the potentialities brought by Artificial Intelligence and document when AI brings added-value and when it does not.

Hierarchical Flow Architectures in Heat Transfer

Abstract


Challenges in Mechanism Design for Robotics and Mechatronics can be considered from several viewpoints in technical, social, and financial ones as due to new designs and applications, mainly in service fields. In this lecture the main issues are discussed in terms of Innovation aspects coming from Mechanism Design. The attention is focused on challenging aspects that are related to the mechanical structure of a modern system as for the structure and operation when considering assigned tasks either in substituting or helping human operators. The lecture presents aspects emphasizing the role of mechanism design in developments of robotic systems as based on the fact that the action in performing tasks, either in coordination or not with human operators, is of mechanical nature due to motion and force transmission goals of the operation. The challenges of mechanism design are presented both in terms of technical solutions and community activity, since each of them depends, impacts, and generates each other. Examples of past and current solutions are presented to show how a mechanism design can be determinant for novel successful achievements and community developments. In particular, the activities at LARM2 in Rome are outlined on topics and systems that can be available for collaborations both in research and joint student formation.

Unravelling the Complexity of Vibroimpact Systems

Abstract


Vibroimpact (VI) systems, characterised by the interaction of continuous vibration and sudden impacts, have been a focal point of nonlinear dynamics research since the early 20th century. These systems typically involve moving components that collide with each other, resulting in energy transfer and giving rise to complex, often unpredictable behaviours. The study of non-smooth dynamics in such systems has advanced considerably, especially with the development of bifurcation theory and chaos theory, which have revealed the intricate dynamics that emerge in systems with impacts. This work also introduced a new class of bifurcations—grazing bifurcations—which are especially characteristic of VI and other non-smooth systems. Grazing bifurcations occur when the trajectory of a system’s motion becomes tangential to the impact boundary, leading to a zero-velocity impact and a sudden, qualitative change in the system’s dynamics.


This presentation will begin with a historical overview of vibroimpact (VI) systems and their diverse applications, followed by an exploration of the complex non-smooth dynamics within a vibroimpact pair. In this system, a freely moving ball collides with dielectric membranes inside a harmonically excited capsule. These impacts deform the membranes, altering their capacitance and enabling efficient energy harvesting. The stability conditions for different types of motion, along with transitions to other motion states, will be examined in detail, including the interplay between ghost period-doubling and grazing bifurcations. Additionally, the system’s role as a vibroimpact nonlinear energy sink (VI-NES), passively mitigating excess vibrations through targeted energy transfer, will be discussed. Both applications rely on the same fundamental impact mechanics, with system parameters and bifurcation patterns dictating performance. A thorough understanding of these dynamics is crucial for optimising both energy harvesting efficiency and vibration mitigation effectiveness. While it may seem intuitive that increasing the mass ratio would enhance VI-NES efficiency by facilitating energy transfer, this relationship is, in fact, more complex. Higher mass ratios can sometimes degrade performance, introducing adverse effects that counteract the benefits of energy absorption. The computational framework we have adopted, based on exact maps, enables a precise investigation of both periodic and chaotic regimes, as well as stable and unstable solution branches. This method overcomes the limitations of traditional approaches, providing new insights into the dynamics of vibroimpact systems and their NES properties, shedding light on previously unobserved features.


Finally, a key challenge in analysing VI systems is studying their global dynamics, as classical methods, such as the Lyapunov exponent, are not effective in non-smooth setups. To address this issue, we present a novel computational method that simplifies the global stability problem by reducing it to a classical cobweb analysis, a technique well-known for its application to smooth, classical systems.

Dynamics of Self-Heating and Hot Surface Ignition

Abstract


Ignition of flammable gases, combustible liquids, or powders is a critical safety concern that engineers face in various industries. One way in which ignition may occur is through the process of self-heating due to positive feedback between reaction rates, energy release, and multiplication of reactive species. If self-heating results in an uncontrolled or runaway reaction this may culminate an explosive combustion event. Another closely related process is ignition by a hot surface introduced either deliberately or accidently into a flammable gas. Self-heating and ignition by hot surfaces in gases are closely related in that ignition occurs within a region of nonuniform temperature created by a combination of heat transfer, fluid motion, and energy released by chemical reactions. I will describe laboratory experiments and companion analyses using numerical simulations to illustrate the analysis of self-heating and thermal ignition thresholds in terms of the balance between chemical, thermal, and fluid motion processes for a variety of geometric and heat transfer configurations. A unifying concept is the existence of critical thermal gradient and chemical length scales leading to nondimensional parameters characterizing the threshold conditions for ignition.

Chemo-mechanics: from delamination of adhesive joints to failure of Li ion batteries

Abstract


The coupling of mechanics to chemistry reveals itself in a wide range of phenomena ranging from stress corrosion cracking to the failure of Li ion batteries. For example, stress can influence diffusion by altering the thermodynamics and/or kinetics. The coupling follows directly from an Onsager-type formalism. Two examples are considered here.


Failure of Li ion batteries
Li ion batteries discharge by the transport of Li ions from an anode (such as graphite or Li metal) to a cathode comprising ceramic particles that swell upon lithiation. The next generation of batteries comprise cathode particles in the form of single crystals made from layered nickel rich materials. Recently, optical microscopy has been performed that reveal the diffusion of Li within these single crystals (“Operando visualisation of kinetically-induced lithium heterogeneities in single-particle layered Ni-rich cathodes” by Chao Xu, Alice J. Merryweather, Shrinidhi S. Pandurangi, Zhengyan Lun, David S. Hall, Vikram S. Deshpande, Norman A. Fleck, Christoph Schnedermann, Akshay Rao, Clare P. Grey, Joule 6, pp. 1-12, 2022.) This allows for a direct comparison with a fully coupled chemo-mechanical model of Li diffusion, including the role of stress. Predictions reveals that the level of induced stress in the single crystals is sufficient to induce cracking when the particles are large and the rate of discharge (lithiation) is very fast (full battery discharge in 10 minutes). Additional simulations have also been performed to explore whether a micro-architectured cathode can be designed that does not swell at the macroscopic level despite significant swelling by the active material upon lithiation.


Delamination of adhesive joints
A range of possible mechanisms lead to the progressive delamination of an interface in the presence of a corrosive species. Commonly, elucidation of the dominant mechanism requires critical experiments whereby the sensitivity of corrosion rate to the concentration of components is determined. An example is presented here by combining such experiment with detailed analysis.
The mechanism of aqueous delamination of a methyl methacrylate -based adhesive layer, sandwiched between two steel plates, is probed by starving the specimen of oxygen, by varying the aqueous environment from de-ionised water to water with a high concentration of salt, and by varying the mechanical constraint imposed by the sandwich. Sandwich construction starves the delamination crack tip of oxygen, and delamination occurs by water attack of the interface. In contrast, an adhesive coating on a steel substrate undergoes cathodic delamination when oxygen is present at the crack tip and the delamination crack is filled with salt water.
The experimental investigation is supported by a theoretical study on the initiation and growth of a crack from a pre-existing delamination; growth is due to the diffusion of a corrosive species from the side face of a sandwich layer. The corrodent diffuses along the delamination and simultaneously through the sandwich layer. It is envisaged that a chemical reaction occurs on the intact interface ahead of the delamination tip, at a rate that scales with the local concentration of corrodent. Debonding initiates at the tip of the pre-existing delamination when a critical quantity of corrodent per unit area has reacted at the interface immediately ahead of the tip. Maps are constructed to show regimes of behaviour, with axes that make use of the sandwich layer geometry and the relative diffusivity of corrodent within the delamination crack and within the sandwich layer. A number of asymptotic solutions shed light on the general numerical case. The analysis is motivated by the practical problem of delamination of adhesive joints employed in ship construction, but has much wider applicability.

A guiding philosophy has been to condense practical engineering design problems into fundamental problems in mechanics, then generate constitutive models and implement them within finite element code.
Examples are the compressive failure of engineering composites by micro buckling, sintering of thermal barrier coatings and the dependence of their toughness and erosion resistance upon morphology of microstructure, the coupled electro-mechanical switching of ferroelectric devices, fatigue life prediction, the mechanics of metal rolling of thin foil, size effects in plasticity effects from hardness testing to cleavage at crack tips, and more recently coupled electro-mechanical phenomena in solid state lithium ion batteries.
Fleck has made particular impact upon the theory and experimental underpinning of strain gradient plasticity; the invention, synthesis, property measurement and theory of micro-architectured solids ranging from metallic foams to multi-phase, multi-scale lattices.

Flow Boiling Heat Transfer Under High Reduced Pressures: Applications, Experimental Data, and a New Mechanistic Model

Abstract


The cooling of electronic devices and, most recently, the widespread use of the Organic Rankine Cycle (ORC) and industrial heat pumps have made the study of flow boiling of organic refrigerants under high reduced pressure a major subject of research in the field of heat transfer. This demand is also driven by environmental constraints that dictate the use of refrigerants that promote high-efficiency thermodynamic cycles and have low global warming potential (GWP) and zero ozone depletion potential (ODP). In this context, the present talk initially provides an overview of these technologies, discussing their pros and cons, limitations, and research needs with a focus on the evaporation process. Next, the main findings of a comprehensive experimental study on flow boiling under high reduced pressure, conducted at the Fluid Mechanics and Thermal Engineering Laboratory (LETeF) at the University of São Paulo (USP), are presented. This analysis revealed that the available flow boiling prediction methods failed to predict this database. This is because these methods were generally developed based on experimental data obtained under low reduced pressure, as their main focus was on refrigeration and air conditioning applications. Additionally, most of these methods do not incorporate the physics of the heat transfer phenomenon because they are based on the asymptotic sum of nucleate boiling and convective effects, rather than modeling bubble dynamics and two-phase flow characteristics. To address this gap in literature, a novel mechanistic model for heat transfer during flow boiling is introduced. This model considers liquid film behavior, bubble nucleation site density, and the bubbles life cycle and is based on a broader database obtained at LETeF comprising low and high reduced pressure experimental data.

Abstract


Composite Overwrapped Pressure Vessels (COPV) are well-known for characteristics like high strength-to-weight ratio, toughness, and weather resistance. Their overall improved performance compared to metals enables significant weight savings, which is driving growing worldwide demand in applications such as CNG and hydrogen cylinders for vehicles, gas transport, and others. Despite these advantages, and their use abroad for more than two decades, COPV have not yet entered the Brazilian market. This keynote will explore the general challenges (both technical and non-technical) and present recent developments by the group in manufacturing Type IV COPV using glass-fiber and carbon-fiber composites via the filament winding technique. The group’s work on raw-material development and the design of COPV through numerical studies to identify optimal laminate sequences will also be discussed.

Dynamics of micro/macro electromechanical systems without/with heredity powered by bio-inspired electronic oscillators

Abstract


In recent years, the effects of heredity on dynamical systems have been analyzed using the fractional order derivative. But, another way of considering the heredity is the integral formulation proposed by Volterra in 1912 and later almost forgotten. Bio-inspiration is the design of technical and technological devices working almost as biological entities for medical or other practical purposes. The seminar will consist of three main steps: (i) presentation of some bio-inspired electronic oscillators, (ii) analysis of the Volterra’s integral formulation of the heredity on the behaviors of nonlinear mechanical oscillators, (ii) presentation of some theoretical and experimental results obtained when using bioinspired electronic oscillators to power micro/macro electromechanical systems with and without heredity consideration.
