Résumé :
Processes for evaluating software architecture (SA) help to investigate problems and potential risks in SA. It is derived from many studies that proposed a plethora of systematic SA evaluation methods, while industrial practitioners currently refrain from applying them since they are heavyweight. Nowadays, heterogeneous software architectures are organized based on the new infrastructure. Hardware and associated software allow different systems, such as embedded, sensor-based, modern AI, and cloud-based systems, to cooperate efficiently. It brings more complexities to SA evaluation. Alternatively, lightweight architectural evaluation methods have been proposed to satisfy the practitioner’s concerns, but practitioners still do not adopt these methods. This study employs a systematic literature review with a text analysis of SA’s definitions to propose a comparison framework for SA. It identifies lightweight features and factors to improve the architectural evaluation methods among industrial practitioners. The features are determined based on the practitioner’s concerns by analyzing the architecture’s definitions from stakeholders and reviewing architectural evaluation methods. The lightweight factors are acquired by studying the five most commonly used lightweight methods and the Architecture-based Tradeoff Analysis Method (ATAM), the most well-known heavyweight method. Subsequently, the research addresses these features and factors.

Résumé :
Lightweight cryptography offers significant security service in constrained environments such as wireless sensor networks and Internet of Things. The focus of this article is to construct lightweight SPN block cipher architectures with substitution box based on finite fields. The paper also details the FPGA implementation of the lightweight symmetric block cipher algorithm of SPN type with combinational S-box. Restructuring of traditional look-up-table Substitution Box (S-Box) sub-structure with a combinational logic S-box is attempted. Elementary architectures namely the basic round architecture and reduced datawidth architecture incorporating look-up-table and combinational S-Box substructure are compared in terms of area and throughput. Proposed restructure mechanism occupies less FPGA resources with no comprise in the latency and also demonstrates performance efficiency and low power consumption in Xilinx FPGAs. Robustness of the proposed method against various statistical attacks has been analyzed through comparison with other existing encryption mechanisms.

Résumé :
In recent years, convolutional neural network architectures have become increasingly complex to achieve improved performance on well-known benchmark datasets. In this research, we have introduced G-Net light, a lightweight modified GoogleNet with improved filter count per layer to reduce feature overlaps, hence reducing the complexity. Additionally, by limiting the amount of pooling layers in the proposed architecture, we have exploited the skip connections to minimize the spatial information loss. The suggested architecture is analysed using three publicly available datasets for retinal vessel segmentation, namely DRIVE, CHASE and STARE datasets. The proposed G-Net light achieves an average accuracy of 0.9686, 0.9726, 0.9730 and F1-score of 0.8202, 0.8048, 0.8178 on DRIVE, CHASE, and STARE datasets, respectively. The proposed G-Net light achieves state-of-the-art performance and outperforms other lightweight vessel segmentation architectures with fewer trainable number of parameters.

Résumé :
<p>The lightweight cryptography is used for low available resources devices such as radio frequency identification (RFID) tags, internet of things (IoTs) and wireless sensor networks. In such case, the lightweight cryptographic algorithms should consider power consumption, design area, speed, and throughput. This paper presents a new architecture of mCrypton lightweight cryptographic algorithm which considers the above-mentioned conditions. Resource-shared structure is used to reduce the area of the new architecture. The proposed architecture is implemented using ISE Xilinx V14,5 and Spartan 3 FPGA platform. The simulation results introduced that the proposed design area is 375 of slices, up to 302 MHz operating frequency, a throughput of 646 Mbps, efficiency of 1.7 Mbps/slice and 0.089 Watt power consumption. Thus, the proposed architecture outperforms similar architectures in terms of area, speed, efficiency and throughput.</p>

Résumé :
Liver segmentation is a prerequisite for various hepatic interventions and is a time-consuming manual task performed by radiology experts. Recently, various computationally expensive deep learning architectures tackled this aspect without considering the resource limitations of a real-life clinical setup. In this paper, we investigated the capabilities of a lightweight model, UNeXt, in comparison with the U-Net model. Moreover, we conduct a broad analysis at the micro and macro levels of these architectures by using two training loss functions: soft dice loss and unified focal loss, and by substituting the commonly used ReLU activation function, with the novel Funnel activation function. An automatic post-processing step that increases the overall performance of the models is also proposed. Model training and evaluation were performed on a public database—LiTS. The results show that the UNeXt model (Funnel activation, soft dice loss, post-processing step) achieved a 0.9902 dice similarity coefficient on the whole CT volumes in the test set, with 15× fewer parameters in nearly 4× less inference time, compared to its counterpart, U-Net. Thus, lightweight models can become the new standard in medical segmentation, and when implemented thoroughly can alleviate the computational burden while preserving the capabilities of a parameter-heavy architecture.

Résumé :
Convolutional Neural Networks (CNNs) have been widely used in Artificial Intelligence applications due to their unsupervised feature, which automatically identifies relevant features without human intervention. Outperforming power-hungry GPUs and inflexible ASICs in lightweight CNNs, FPGAs serve as a promising platform on balancing peak performance, energy efficiency and flexibility. In the last decade, several frameworks have been proposed to optimize the global performance of CNN on hardware platforms. This paper presents a survey on hardware architectures generated by various software frameworks designed for mapping CNN on FPGAs. Classic architectural cases of the streaming architecture and the single computation engine from traditional CNN-specific processors to end-to-end mapping using High Level Synthesis (HLS) tools which emerged in recent years are carefully analyzed in a sequential order. Moreover, adaptability of existing frameworks to upcoming challenges and future directions of FPGA-based CNN accelerators are identified, providing an in-depth evaluation on the topic of hardware architectures of FPGA-based CNN accelerators.

Résumé :
Modern internet of things (IoT) applications can benefit from advanced communication paradigms, including multicast and anycast. Next-generation internet architectures, such as information-centric networking (ICN), promise to support these paradigms, but at the same time they introduce new security challenges. This paper presents a solution that extends an ICN-like architecture based on software-defined networking (SDN) that supports those communication paradigms. Using the proposed solution, the underlying architecture is enhanced with a novel security mechanism that allows content “advertisements” only from authorized endpoints. This mechanism prevents “content pollution”, which is a significant security threat in ICN architectures. The proposed solution is lightweight, and it enables identity sharing as well as secured and controlled identity delegation.

Résumé :
Our aim was to optimize a SOA control system by evolving the architecture of the service component that transforms system models into task trees, which are then executed by the runtime library called the Task Tree Executor, TTE. In the paper we present the two novel TTE architectures that evolved from the previous TTE architecture and introduced finer grained parallelism. The novel architectures execute TTE tasks as more lightweight TBB tasks and Cilk strands rather than the OS threads, which was the case for the previous TTE architecture. The experimental evaluation based on time needed for TTE reliability estimation, by statistical usage tests, shows that these novel TTE architectures are providing the average relative speedup, RS, from 8x to 11x, over the original TTE, on a dual-core machine. Additional experiments made on eight-core machine showed that RS provided by TTE based on TBB scales perfectly, and goes up to 77x.

Résumé :
There is a significant effort in building lightweight cryptographic operations, yet the proposed solutions are typically single purpose modules that can only provide a fixed functionality. However, flexibility is an important aspect of cryptographic designs where a module can perform multiple operations with different configurations. In this work, we combine flexibility with lightweight designs and propose two cryptographic engines based on the SIMON block cipher. The first proposed engine is the Flexible SIMON, which can execute all configurations of SIMON thus enables an adaptive security with variable key sizes. Our second proposed implementation is BitCryptor, a bit-serialized Compact Crypto Engine that can perform symmetric key encryption, hash computation and pseudo-random-number-generation. The implementation results on a Spartan-3 s50 FPGA show that the proposed engines occupies 90 and 95 slices respectively, which are more compact than the majority of their single purpose counterparts. Therefore, these engines are suitable cryptographic blocks for resource-constrained systems.

Résumé :
En reconnaissance d’écriture manuscrite, les architectures Transformer permettent de faibles taux d’erreur, mais sont difficiles à entraîner avec le peu de données annotées disponibles. Dans ce manuscrit, nous proposons des architectures Transformer légères adaptées aux données limitées. Nous introduisons une architecture rapide basée sur un encodeur Transformer, et traitant jusqu’à 60 pages par seconde. Nous proposons aussi des architectures utilisant un décodeur Transformer pour inclure l’apprentissage de la langue dans la reconnaissance des caractères. Pour entraîner efficacement nos architectures, nous proposons des algorithmes de génération de données synthétiques adaptées au style visuel des documents modernes et anciens. Nous proposons également des stratégies pour l’apprentissage avec peu de données spécifiques, et la réduction des erreurs de prédiction. Nos architectures, combinées à l’utilisation de données synthétiques et de ces stratégies, atteignent des taux d’erreur compétitifs sur des lignes de texte de documents modernes. Sur des documents anciens, elles parviennent à s’entraîner avec des nombres limités de données annotées, et surpassent les approches de l’état de l’art. En particulier, 500 lignes annotées sont suffisantes pour obtenir des taux d’erreur caractères proches de 5%

We also present architectures using a Transformer decoder to incorporate language modeling into character recognition. To effectively train our architectures, we offer algorithms for generating synthetic data adapted to the visual style of modern and historical documents. Finally, we propose strategies for learning with limited data and reducing prediction errors. Our architectures, combined with synthetic data and these strategies, achieve competitive error rates on lines of text from modern documents. For historical documents, they train effectively with minimal annotated data, surpassing state-ofthe- art approaches. Remarkably, just 500 annotated lines are sufficient for character error rates close to 5%

What will be the fundamental aspect and concern of today's good design? As global energy reserves deplete over the coming decades, a strategy of reduced consumption will be essential to the production of furniture and architecture, alike. A lightweight design strategy is a way for designers to participate in reducing the environmental footprint of everyday objects. We are witnessing a Paradigm shift in design and the decorative arts of a magnitude not seen since the Modernist movement in the early 20th century. A design style embraces the combination of sustainability with building production. Today we recognizes that our resources are finite and that careful consideration should be given to the building process. Since ecological concern of materials become one of the foremost issues of today's building industry, For this project, I developed a lightweight and low-cost framing system that is collapsible and easy to assemble. My goal is to create compelling designs in the hope they will inspire people to choose sustainable design over safer and more traditional designs. Making building from thin bent plywood yields 9-10 times more usable wood from a log than making a building from hardwood lumber During the production of plywood, only 15 percent of the wood from a log is lost to waste. On the other hand , the average waste it takes to make a finished solid wood frame building is 1.5 times more wood than is used in the building itself! Bent plywood has been utilized by a mere handful of designer, most notably Alvar Aalto and Charles and Ray Eames, but the application of this material remained in furniture scale.
(cont.) Since the creative potential of this material is still largely unexplored. My motivation is to extend the application of this very particular thin material-plywood.

Lightweight architecture questions how we architects think about the environment. It has qualities which complement "mainstream" buildings. This thesis will explore these qualities and will propose that this architecture is rooted in the modern sensibility and suggests an attitude towards the environment that is needed in our cities. Lightweight architecture is concerned with optimal and, particularly, parsimonious use of materials and effort. Much lightweight architecture is tensile as structures loaded in tension use the least amount of material. Now that modern technology and materials have opened up possibilities· in research and application, much of the research has been done and is no longer the exclusive realm of trained engineers. The question of application of this technology remains -- this is up to the architects. The style of lightweight architecture can be looked at in terms of aesthetic, the process by which one develops its forms and the way of thinking from which it arises. The aesthetic of lightweight architecture enriches the traditional aesthetic notion familiar to us (symmetry, proportion and balance) with the more elusive notions of dynamic symmetry, relative harmony and equilibrium. Form-finding is an experimental process of trial and error. It stems not only from the scientific discipline of static, but from other disciplines , explored from without. In this way, unexpected combinations appear. Complementing static research into the minimal use of materials, vernacular constructions and biology have been used for a greater understanding of parsimony in building. The "logic of reasoning" refers to a creator's conception of the world in which one creates. The designers of lightweight architecture believe in a world not of specialization and analysis, but of creation and adaption, an ecological view of the world. Because the process of creation is more important that the resultant form, the syntactics of structural and formal assembly takes precedence on an analogical basis for form-finding.The second section of this thesis explores lightweight architecture in the city. The current trend of placing lightweight buildings in parks rejects the possibilities of lightweight architecture can offer the city. Many architects see a conflict in the juxtaposition of lightweight buildings against traditional load-bearing urban "fabric". Lightweight architecture implies notions of boundary and mutability that are contrary to these same notions as represented in industrial cities. Being ephemeral, mobile and adaptable, this architecture, by its unboundedness, forces us to re-assess our notion of boundary. Lightweight architecture, allows for a rapid adaption of buildings in the city to climatic change and for the periodic gathering of festivals and markets. The adaptive, mutable qualities lightweight architecture can bring to the city are particularly valuable for urban public spaces. This architecture allows for human engagement with the environment and with each other. The load-bearing wall and its function in the city -- the separation of one activity from another and the definition of privacy -- has been radically redefined by the advent of the glass curtain wall and the telephone. This process has left us with ambiguous urban "public" spaces not much used by the public yet not truly private. Re-introducing a mobile, lightweight ephemeral architecture into post-industrial cities is a desire to implement certain socio-political ideas about city culture and simultaneously make places where those policies are lived.

Résumé :
Abstract. The involvement of low power Internet of Things (IoT) devices in the Wireless Sensor Networks (WSN) allow enhanced autonomous monitoring capability in many application areas. Recently, the principles of edge computing paradigm have been used to cater onsite processing and managing actions in WSNs. However, WSNs deployed in remote sites require human involvement in data collection process since internet accessibility is still limited to population dense areas. Nowadays, researchers propose UAVs for monitoring applications where human involvement is required frequently. In this thesis work, we introduce an edge-based architecture which create end-to-end secure communication between IoT sensors in a remote WSN and central cloud via UAV, which assist the data collection, processing and managing procedures of the remote WSN. Since power is a limited resource, we propose Bluetooth Low Energy (BLE) as the communication media between UAV and sensors in the WSN, where BLE is considered as an ultra-low power radio access technology. To examine the performance of the system model, we have presented a simulation analysis considering three sensor nodes array types that can realize in the practical environment. The impact of BLE data rate, impact of speed of the UAV, impact of distance between adjacent sensors and impact of data generation rate of the sensor node have been analysed to examine the performance of system. Moreover, to observe the practical functionality of the proposed architecture, prototype implementation is presented using commercially available off-the-shelf devices. The prototype of the system is implemented assuming ideal environment.

The purpose of this study is to investigate the benefits of adding natural fiber tensile reinforcement to aerated concrete. Concrete is a great composite material which can be created in various proportions and with various materials to alter its strength, density and porosity, amongst other properties. Concrete which is used commonly in construction of columns, beams, and slabs acts well in compression but fails under tension. The common solution is to reinforce the structure in areas where it experiences tension with steel. There are other materials besides steel which also take tension well. Natural fibers for example come in various strengths and types and would create lighter and perhaps more sustainable beam designs. Natural fibers have been used for their availability, workability, and high tensile strengths for centuries. This research discovers how the natural fibers distribute within the mixture and how they affect the aeration of the concrete, as well as how they affect the strength. Multiple samples are cured with different fiber types and in different proportions within the mixture. Furthermore, similar experimentation is conducted to discover an ideal ratio of aggregate to aerated concrete mix. The aggregate gives the concrete greater strength and economy, but could negatively affect the aeration. The various concrete mixes are poured and allowed to cure to maximum strength before indirect tensile tests and compression tests are conducted. The effects of creating smooth aerated concrete molds are also investigated. All experiments conducted are precursory to an ultimate tensile reinforced aerated concrete beam design with an aggregate mix and smooth surfaces.

The purpose of this thesis it to examine the effects of utilizing control to better meet performance and systematic requirements of future space telescopes. New telescope systems are moving toward tighter optical performance requirements with lower mass and cost, creating an implicit conflict for currently designed systems. Therefore, new technology and telescope types must be developed and implemented, and a key to lightweight systems is the addition of controls. This thesis uses an integrated modeling technique to examine a large tradespace of space telescope systems. The analysis techniques includes finite element and dynamic disturbance analyses to determine the effects of various parameters on overall system performance metrics. In particular, this thesis will focus on the control system architecture for future space telescopes. As systems become less massive, more control is necessary to meet the performance requirements. Less massive systems have more flexibility, which degrades performance. Thus, this flexibility must be controlled to obtain adequate performance. However, the control also has a cost that must be considered.
(cont.) As the areal density of the mirror decreases, the cost due to mass decreases, but the cost due to control increases because more control is required to meet the requirements. Therefore, a balance between lightweight systems and control is sought to give the best overall performance. Additionally, there are many different types of control that could be used on the system, thus finding optimal combinations of controllers, sensors, actuators, and bandwidths is a daunting task. The integrated modeling technique allows the designer to examine the effects of structural parameters and requirements on the control system architecture and the performance metrics. The ability to determine favorable control system architectures early in the design process will allow new technologies to be pushed further, while still maintaining confidence that the system will perform as expected.

This research focuses on the intersection between material composition and form in the development of a new type of concrete. As concrete is the most widely used building material in the world, innovation in this material has more potential to effect change in our built environment than innovation in any other. With the objective of minimizing raw material consumption and energy use, this work attempts to develop methods for creating a cellular lightweight concrete with variable density that can be cured at room temperature. Most aerated concretes traditionally require high temperature and high pressure curing; the goal of this research is to create a lower embodied energy product through the use of room temperature curing, while at the same time maximizing performance through variation of the density of the material through its section-essentially locating stronger material where it is needed. This more durable and versatile concrete product will be able to compete with traditional lightweight concretes, which provide benefits such as insulation, as well as normal-weight concrete, which is harder and stronger. The research aims to capitalize on the inherent heterogeneity of the material by producing a substance whose internal properties can be varied based on the needs of a specific part of a building. I am interested in replacing the concept of the "assembly" of materials to gain a desired function with a more unitary concept: the manipulation of a single material to meet a building's multiple needs. A desired outcome of the work is to reconceive how we put buildings together, not as assemblies of discrete elements but as monolithic yet malleable wholes.
