Security Trade-offs in Cyber Physical Systems: A Case Study Survey on Implantable Medical Devices

The new culture of networked systems that offer everywhere accessible services has given rise to various types of security trade-offs. In fact, with the evolution of physical systems that keep getting integrated with cyber frameworks, cyber threats have far more critical effects as they get reflected on the physical environment. As a result, the issue of security of cyber physical systems requires a special holistic treatment. In this paper, we study the trade-off between security, safety and availability in such systems and demonstrate these concepts on implantable medical devices as a case study. We discuss the challenges and constraints associated with securing such systems and focus on the trade-off between security measures required for blocking unauthorized access to the device, and the safety of the patient in emergency situations where such measures must be dropped to allow access. We analyze the up to date proposed solutions and discuss their strengths and limitations

Strategic group mapping and strategy canvas analysis of the environmental consulting sector : a project-based dissertation on the German Market : a public archival data web-content analysis

Nesta dissertação na modalidade de projeto tive a oportunidade de entrar em contacto com uma Pequena Média empresa no setor de consultoria ambiental, onde me foi pedido para realizar uma análise à competição no mercado alemão, focando-me em mercados específicos em que a empresa se planeia especializar (Nanomateriais, Biocidas e Instrumentos Médicos). É possível observar que as leis ambientais mais restritivas, desenvolvimentos dentro da química e consciência ambiental estão a criar um grande potencial para crescimento e relevância deste setor. Gestão estratégica e categorização estratégica desenvolveram muitas correntes de pesquisa e no entanto, ferramentas estratégicas ainda não foram utilizadas para analisar o setor da Consultoria ambiental, que tem sido negligenciado na literatura. Através de uma análise de dados de arquivamento públicos (websites, páginas de LinkedIn, e relatórios anuais), foi possível aplicar ferramentas estratégicas (Mapeamento de grupos estratégicos e o Canvas estratégico) a uma amostra de 57 empresas de consultoria ambiental no mercado alemão assim como recolher sinais de competitividade e tamanho das empresas. Nesta análise pode-se comprovar que a revolução digital, sustentabilidade e responsabilidade corporativa já se encontram presentes nesta indústria, que várias empresas oferecem tanto apoio ambiental com foco regulatório e de gestão como um apoio ambiental com foco cientifico, procurando eficiência ambiental e redução de desperdício, e que nanomateriais parecem ser o mercado menos presente em websites, comparativamente com o mercado dos biocidas e dos instrumentos médicos. Este trabalho permitiu demonstrar o valor que ferramentas estratégicas podem ter, mesmo quando aplicado a informação publica, neste caso de websites, e também demonstrar as respetivas limitações, permitindo-nos ter uma melhor visão das nuances estratégicas e estrutura de um setor negligenciado. Para além disso, o contexto da análise estratégica também demonstra que o Brexit pode agir como um catalisador de expansão geográfica, o que é um impacto estratégico que ainda não tinha sido estudado previamente em empresas nesta indústria.In this project-based dissertation I had the chance to work with an environment consulting SME, where I was asked to do a competitor analysis of the German Market in particular sectors in which they will focus on (Nanomaterials, Biocides and Medical Devices). It is possible to observe that the increasingly stringent environmental policies, chemistry developments and environmental consciousness are creating a great potential for the growth in size and relevance of this sector. Strategic management and strategic categorization have developed into many streams of research, and however, strategic tools still haven’t been used to describe the environmental consulting sector, which has been overlooked in the literature. Through an analysis of public archival data (Company website, LinkedIn and annual reports), it was possible apply the Strategic group mapping and Strategy canvas frameworks to a sample of 57 environmental consulting companies in the German market, as well as to collect other signs of competitiveness and size. In this analysis it was found that the digital revolution, sustainability and corporate responsibility are already present in this industry, it was found that many companies are providing not only environmental regulatory and managerial support but at the same time providing scientific support, focusing on environmental efficiency and waste management, and that nanomaterials seem to be the least featured market in companies websites comparatively to biocides and medical devices. This paper allowed to demonstrate the value that strategic tools can have, even when applied to public website-content, as well as to demonstrate their limitations, allowing us to give a better overview of the strategic nuances and structure of an overlooked sector. Moreover, the context of this company’s strategic analysis also showcases that Brexit can act as a catalyst of geographical expansion, which is a strategical impact in this industry that hasn’t been studied before for companies in this industry

Brave New Wireless World: Mapping the Rise of Ubiquitous Connectivity from Myth to Market

This dissertation offers a critical and historical analysis of the myth of ubiquitous connectivity—a myth widely associated with the technological capabilities offered by “always on” Internet-enabled mobile devices like smartphones and tablets. This myth proclaims that work and social life are optimized, made more flexible, manageable, and productive, through the use of these devices and their related services. The prevalence of this myth—whether articulated as commercial strategy, organizational goal, or mode of social mediation—offers repeated claims that the experience and organization of daily life has passed a technological threshold. Its proponents champion the virtues of the invisible “last mile” tethering individuals (through their devices) primarily to commercial networks. The purpose of this dissertation is to uncover the interaction between the proliferation of media artifacts and the political economic forces and relations occluded by this myth. To do this, herein the development of the BlackBerry, as a specific brand of devices and services, is shown to be intimately interrelated with the myth of ubiquitous connectivity. It demonstrates that the BlackBerry is a technical artifact whose history sheds light on key characteristics of our media environment and the political economic dynamics shaping the development of other technologies, workforce composition and management, and more general consumption proclivities. By pointing to the analytic significance of the BlackBerry, this work does not intend to simply praise its creators for their technical and commercial achievements. Instead, it aims to show how these achievements express a synthesis that represents the motivations of economic actors and prevailing modes of thought most particularly as they are drawn together in and through the myth of ubiquitous connectivity. The narrative arc of this dissertation is anchored by moments of harmonization among political economic interests as these shape (and are shaped by) prevailing modes of producing and relating through ubiquitous connectivity

Security and privacy for the internet of medical things enabled healthcare systems: a survey

With the increasing demands on quality healthcare and the raising cost of care, pervasive healthcare is considered as a technological solutions to address the global health issues. In particular, the recent advances in Internet of Things have led to the development of Internet of Medical Things (IoMT). Although such low cost and pervasive sensing devices could potentially transform the current reactive care to preventative care, the security and privacy issues of such sensing system are often overlooked. As the medical devices capture and process very sensitive personal health data, the devices and their associated communications have to be very secured to protect the user's privacy. However, the miniaturized IoMT devices have very limited computation power and fairly limited security schemes can be implemented in such devices. In addition, with the widespread use of IoMT devices, managing and ensuring the security of IoMT systems are very challenging and which are the major issues hindering the adoption of IoMT for clinical applications. In this paper, the security and privacy challenges, requirements, threats, and future research directions in the domain of IoMT are reviewed providing a general overview of the state-of-the-art approaches

Deep Learning in Breast Cancer Imaging: A Decade of Progress and Future Directions

Breast cancer has reached the highest incidence rate worldwide among all malignancies since 2020. Breast imaging plays a significant role in early diagnosis and intervention to improve the outcome of breast cancer patients. In the past decade, deep learning has shown remarkable progress in breast cancer imaging analysis, holding great promise in interpreting the rich information and complex context of breast imaging modalities. Considering the rapid improvement in the deep learning technology and the increasing severity of breast cancer, it is critical to summarize past progress and identify future challenges to be addressed. In this paper, we provide an extensive survey of deep learning-based breast cancer imaging research, covering studies on mammogram, ultrasound, magnetic resonance imaging, and digital pathology images over the past decade. The major deep learning methods, publicly available datasets, and applications on imaging-based screening, diagnosis, treatment response prediction, and prognosis are described in detail. Drawn from the findings of this survey, we present a comprehensive discussion of the challenges and potential avenues for future research in deep learning-based breast cancer imaging.Comment: Survey, 41 page

Impact of EU Medical Device Directive on Medical Device Software

Directive 2007/47/EC of the European Parliament amending Medical Device Directive (MDD) provides medical device manufacturers with a compliance framework. However, the effects of the amendments to the MDD on competition in the U.S. medical device software industry are unknown. This study examined the impact of this directive on the competitiveness of U.S. medical device software companies, the safety and efficacy of medical device software, employee training, and recruitment. The conceptual framework for this study included 3 dimensions of medical device regulations: safety, performance, and reliability. The overall research design was a concurrent mixed method study using both quantitative and qualitative techniques. The qualitative techniques involved case studies of 5 purposively selected companies. Data collection involved both surveys and interviews. The sample consisted of 56 employees within medical device firms with markets around the European regions. Qualitative data analysis consisted of descriptive thematic analysis along the study questions and hypotheses and summative evaluation. Quantitative data analysis included descriptive statistics and correlation to test the 4 hypotheses. The results suggested that the MDD has realigned medical device software manufacturing practices, and US medical device companies have gained global competitiveness in improving product safety and increasing sales revenue. Key recommendations to medical device manufacturers include adopting MDD 93/42/EEC, using model-based approaches, and being comprehensive in model use. Adopting the MDD will provide positive social change to patients, as human safety improves with better product quality while companies experience fewer product recalls

Digital workflows for the management of existing structures in the pre- and post-earthquake phases: BIM, CDE, drones, laser-scanning and AI

La metodologia BIM, sviluppata in America negli anni '70, ha rivoluzionato l'industria delle costruzioni introducendo i principi di innovazione e digitalizzazione per la gestione dei progetti, in un settore settore produttivo troppo legato a logiche tradizionali. I numerosi processi digitali che sono stati sviluppati da allora hanno riguardato in gran parte la progettazione di nuovi edifici, e sono principalmente legati alla disciplina del construction management. Alcune prime sperimentazioni condotte nel tempo hanno mostrato come l'estensione di questa metodologia agli edifici esistenti comporti molte difficoltà. In questo panorama, il lavoro di tesi si concentra sulla gestione delle strutture nella fase pre e post-sisma con l'obiettivo di sviluppare processi digitali basati sull'uso di tecnologie innovative applicate sia agli edifici ordinari che a quelli storici. Il primo workflow sviluppato, relativo alla fase pre-sisma, è stato denominato scan-to-FEM, ed è finalizzato a particolarizzare il classico processo scan-to-BIM nel campo dell'ingegneria strutturale, analizzando così tutti i passaggi dal rilievo dell'edificio con le tecniche digitali di fotogrammetria e laser-scanning fino all'analisi strutturale e alla valutazione della sicurezza nei confronti delle azioni sismiche. I processi di gestione delle strutture post-sisma sono invece incentrati sulla stima della sicurezza della struttura e sulla definizione delle strategie di intervento, e si basano sull'analisi delle caratteristiche intrinseche della struttura e dei danni indotti dagli eventi sismici. L'intero processo di valutazione del livello operativo di un edificio è stato quindi rivisto alla luce delle moderne tecnologie digitali. Nel dettaglio, sono state sviluppate Reti Neurali Convoluzionali (CNN) per la crack detection, e l'estrazione delle informazioni numeriche associate alle lesioni, gestite poi grazie ai modelli BIM. I quadri fessurativi sono stati digitalizzati grazie allìintroduzione un nuovo oggetto BIM "lesione" (attualmente non codificato nello standard IFC), al quale è stato aggiunto un set di parametri in parte valutati con le CNN ed in parte qualitativi. Durante lo sviluppo di questi processi, sono stati sviluppati nuovi strumenti adhoc per la gestione degli edifici esistenti. In particolare, sono state definite specifiche per lo sviluppo di schede tecniche digitali dei danni, e per la creazione del nuovo oggetto BIM "lesione". I processi di gestione degli edifici danneggiati, grazie agli sviluppi tecnologici realizzati, sono stati applicati per la digitalizzazione dell'edificio storico della chiesa di San Pietro in Vinculis danneggiato a seguito di eventi sismici, grazie ai quali sono stati sperimentati i massimi benefici in termini di riduzione di tempo e risparmio di risorse
