ARM RDN2 and TSS Integration as a System-on-Chip Simulation

System-on-Chip (SoC) technology plays a key role in modern electronic devices by making them smaller, faster, and more energy-efficient. It facilitates this by combining all the main components such as processors and memory into a single chip. Today, SoCs are used in many areas like smartphones, cars, airplanes, and other embedded systems. However, traditional verification methods struggle to detect hardware-software integration issues effectively in early development stages as systems become more complex. One challenge is to detect integration problems between hardware and software components at early stages. This thesis focuses on challenges of the traditional methods by creating a new co-simulation approach. The aim is to use data processing unit that supports up to date ARM processors architecture while keeping the flexibility advantages of Target SoC Simulator (TSS) by replacing QEMU in current framework. Since ARM Fast Models support the latest ARM processor architectures, a platform based on Fast Models was integrated into the framework. As a proof of concept, the ARM Reference Design N2 (RDN2) was selected. The approach is to integrate the ARM RDN2 platform with the TSS to use advantages from both platforms. This thesis mainly explores two primary research questions: Can the ARM RDN2 platform be integrated into the TSS environment without changing the original structure of TSS, and will the combined system maintain synchronization and correct functionality? To answer these questions, a systematic methodology was used. The methodology involved tool selection, integration of platforms through a special interface wrapper for data transfer and testing to ensure synchronization. Results of the early tests showed that the system worked properly. The data was correctly transferred between TSS and ARM RDN2 while both platforms maintaining synchronization by 1 microsecond. This means that the framework is useful for testing hardware and software together before the real silicon is ready. These results suggest that the system can help make SoC design more accurate and reduce development time and cost. Despite these advantages, there were some limitations identified. Integration was complex due to differences in transaction formats and timing models used by TSS and RDN2. Additionally, the system currently lacks interrupt support. Future research should focus on testing this integration with more complex systems, optimizing data transfer speeds, and adding interrupt handling capabilities. This integrated system is a promising way to test precise and reliable early validation in the development of advanced SoC systems. This integration specifically beneficial in fast-paced industries like telecommunications

Longitudinal trajectories of post-traumatic stress disorder (PTSD) after birth and associated risk factors

Background Although longitudinal trajectories of post-traumatic stress disorder (PTSD) are well-established in general trauma populations, very little is known about the trajectories of birth-related PTSD. This study aimed to identify trajectories of birth-related PTSD; determine factors associated with each trajectory; and identify women more likely to develop birth-related PTSD. Method 226 women who had traumatic childbirth according to DSM-IV criterion A were drawn from a community sample of 950 women. Measures were taken of PTSD, affective symptoms, fear of childbirth and social support in pregnancy, 4–6 weeks and 6-months postpartum. Information on some obstetric and psychosocial factors were also prospectively obtained. Results Four trajectories were identified: resilience (61.9%), recovery (18.5%), chronic-PTSD (13.7%) and delayed-PTSD (5.8%). Resilience was consistently distinguished from other PTSD trajectories by less affective symptoms at 4–6 weeks postpartum. Poor satisfaction with health professionals was associated with chronic-PTSD and delayed-PTSD. When affective symptoms at 4–6 weeks postpartum were removed from the model, less social support and higher fear of childbirth 4–6 weeks after birth predicted chronic and recovery trajectories; whereas experience of further trauma and low levels of satisfaction with health professionals were predictive of chronic-PTSD and delayed-PTSD, compared to resilience. Additional variables associated with different trajectories included antenatal affective symptoms, caesarean-section, preterm birth and receiving professional help. Limitations Use of self-report measures, use of DSM-IV criteria for PTSD diagnosis, and no follow-up beyond six months are the main limitations of this study. Conclusion Identified factors may inform preventive and treatment interventions for women with traumatic birth experiences

solveTruss v1.0: Static, global buckling and frequency analysis of 2D and 3D trusses with Mathematica

Trusses have an important place amongst engineering structures due to many advantages such as high structural efficiency, fast assembly and easy maintenance. Iterative truss design procedures, which require analysis of a large number of candidate structural systems such as size, shape and topology optimization with stochastic methods, mostly lead the engineer to establish a link between the development platform and external structural analysis software. By increasing number of structural analyses, this (probably slow-response) link may climb to the top of the list of performance issues. This paper introduces a software for static, global member buckling and frequency analysis of 2D and 3D trusses to overcome this problem for Mathematica users.

Harmonious sensorium. Music center project in Lanzarote

LAUREA MAGISTRALESituato nel mondo naturale extraterrestre di Lanzarote, il progetto mira a studiare la relazione armonica tra musica e architettura concettualizzando la nostra percezione dell'interazione sensoriale per rispondere al nostro essere. 'The Harmonious Sensorium' sarà un mezzo tra l'approccio analogico tra musica e architettura con lo strumento architettonico di solido / vuoto usato come riflesso della notazione all'interno della teoria musicale. Lo sviluppo del processo di progettazione è parallelo alla creazione di un pezzo musicale o architettonico, dalla formazione operativa dei solidi e quindi dal disegno condizionale dei vuoti. Quindi, la prima parte della ricerca si concentra su come la relazione matematica e armonica tra musica e architettura si è sviluppata attraverso la storia, con una comprensione dettagliata di come l'architettura dovrebbe o può riguardare questa affiliazione. La seconda parte si concentrerà sul vuoto, che sta mostrando le caratteristiche sensoriali della mutualità tra musica e architettura. Tali concetti contrastanti di presenza e assenza stanno imitando la relazione tra musica e architettura, come un continuum di interazione per derivare l'analogia in una definizione di un disegno consapevole.Located in the extraterrestrial-like natural world of Lanzarote, the project aims to study the harmonic relation between music and architecture by conceptualizing our perception of sensory interaction to respond to our being. ‘The Harmonious Sensorium’ will be a medium between the analogical approach between music and architecture with the architectural tool of solid/void used as a reflection of notation inside music theory. The development of the design process is paralleled to creation of a musical or architectural piece, by operational formation of the solids and then the conditional design of the voids. Hence, the first part of the research focuses on how the mathematical and harmonic relation between music and architecture has developed through history, with a detailed understanding of how architecture should or can relate to this affiliation. The second part will focus on the void, which is displaying the sensory features of mutuality between music and architecture. Such contrasting concepts of presence and absence are mimicking the relation between music and architecture, as a continuum of interaction to derive the analogy into a definition of a conscious design

Early Neolithic Innovation: Ventilation Systems and the Built Environment

A wide range of rapid innovations are associated with the shift from mobile communities to sedentism in southwestern Asia. It was during this period that human societies generated many solutions designed to overcome the challenges of local environments, including the first long-lasting built environments, while adapting to life in year-round permanent settlements. The technological innovations that went hand in hand with these socio-economic changes improved the lives of the inhabitants of these communities, defining the period as a time of techno-cultural revolutions. Along with the domestication of plants and animals, houses became domestic spaces. Several characteristics of today's architectural technology originated during this period. The paper discusses one of the architectural innovations of the Neolithic period, "ventilation shafts," at one of the earliest settlements in central Anatolia, Asikli Hoyuk
