To stay competitive in today’s fast-paced market, manufacturing companies must shorten their time-to-market and decrease their costs by efficiently utilizing their resources. Here, improved software and better software integration throughout the product realization process is considered to be a key enabler. The aim of this thesis work has been to investigate the current workflow in design and process planning to outline a cloud-based application to support these activities. Pains and bottlenecks in these workflows have been identified through interview and field studies at six Swedish manufacturing companies of different sizes, in different industries, and with different operational models. The major areas of improvement were identified whereof one them, the initial activity of understanding customers’ needs, was decided to further focus on. From receiving a request for quotation from the customer to acceptance of an order, the following time-consuming activities were recognized: understand and discuss design intent as well as suggest possible design changes to improve manufacturability, analyze and review 2D drawings and 3D models, and develop order quotations. In this thesis work, a mock-up prototype has been put forward. The intent with this is to bridge a gap that has been identified through the mapping between manufacturers needs and functionality of available CAD/CAM software and the identified areas of improvement from the workflow investigations. The proposed solution, as presented in the mock-up prototype, has been validated together with three of the studied companies. At its current state, further improvements and validations are needed. Nevertheless, if further developed, it has the potential to create value within the entire manufacturing value chain. / För att vara konkurrenskraftig på dagens snabbrörliga marknad måste tillverkande företag minska sina tid till marknad och reducera sina kostnader genom att utnyttja sina resurser mer effektivt. Här anses förbättrad programvara och bättre mjukvaruintegration genom hela produktrealiseringsprocessen vara en viktig möjliggörare. Målet med detta arbete har varit att undersöka det aktuella arbetsflödet i design och processplanering för att föreslå en molnbaserad applikation för att stödja dessa aktiviteter. Problem och flaskhalsar i dessa arbetsflöden har identifierats genom intervjuer och fältstudier hos sex svenska tillverkande bolag i olika storlekar, i olika branscher och med olika operativa modeller. De viktigaste förbättringsområdena identifierades varav en, den initiala aktiviteten för att förstå kundernas behov, beslutades att ytterligare fokusera på. Från att ha mottagit en offertförfrågan från kunden till acceptans av en beställning kunde följande tidskrävande aktiviteter identifieras: förstå och diskutera designintention samt föreslå möjliga designändringar för att förbättra tillverkningsförmåga, analysera och granska 2D-ritningar och 3D-modeller, och utveckla ordernoteringar. I det här arbetet har en prototyplösning tagits fram. Avsikten med denna är att överbrygga ett gap som har identifierats genom kartläggning mellan tillverkarens behov och funktionalitet av tillgänglig CAD / CAM-programvara och de identifierade förbättringsområdena från arbetsflödesutredningarna. Den föreslagna lösningen, som presenterades i prototypen, har validerats tillsammans med tre av de studerade företagen. Vid sitt nuvarande tillstånd behövs ytterligare förbättringar och valideringar. Om den vidareutvecklas har den dock potentialen att skapa värde för hela tillverkningskedjan.

Longitudinal personalized electronic health record (LPHR) provides a holistic view of health records for individuals and offers a consistent patient-controlled information system for managing the health care of patients. Except for the patients in Veterans Affairs health care service, however, no LPHR is available for the general population in the U.S. that can integrate the existing patients' electronic health records throughout life of care. Such a gap may be contributed mainly by the fact that existing patients' electronic health records are scattered across multiple health care facilities and often not shared due to privacy and security concerns from both patients and health care organizations. The main objective of this dissertation is to address these roadblocks by designing a scalable and interoperable LPHR with patient-controlled and mutually-trusted security and privacy. Privacy and security are complex problems. Specifically, without a set of access control policies, encryption alone cannot secure patient data due to insider threat. Moreover, in a distributed system like LPHR, so-called race condition occurs when access control policies are centralized while decisions making processes are localized. We propose a formal definition of secure LPHR and develop a blockchain-enabled next generation access control (BeNGAC) model. The BeNGAC solution focuses on patient-managed secure authorization for access, and NGAC operates in open access surroundings where users can be centrally known or unknown. We also propose permissioned blockchain technology - Hyperledger Fabric (HF) - to ease the shortcoming of race condition in NGAC that in return enhances the weak confidentiality protection in HF. Built upon BeNGAC, we further design a blockchain-enabled secure and trusted (BEST) LPHR prototype in which data are stored in a distributed yet decentralized database. The unique feature of the proposed BEST-LPHR is the use of blockchain smart contracts allowing BeNGAC policies to govern the security, privacy, confidentiality, data integrity, scalability, sharing, and auditability. The interoperability is achieved by using a health care data exchange standard called Fast Health Care Interoperability Resources. We demonstrated the feasibility of the BEST-LPHR design by the use case studies. Specifically, a small-scale BEST-LPHR is built for sharing platform among a patient and health care organizations. In the study setting, patients have been raising additional ethical concerns related to consent and granular control of LPHR. We engineered a Web-delivered BEST-LPHR sharing platform with patient-controlled consent granularity, security, and privacy realized by BeNGAC. Health organizations that holding the patient's electronic health record (EHR) can join the platform with trust based on the validation from the patient. The mutual trust is established through a rigorous validation process by both the patient and built-in HF consensus mechanism. We measured system scalability and showed millisecond-range performance of LPHR permission changes. In this dissertation, we report the BEST-LPHR solution to electronically sharing and managing patients' electronic health records from multiple organizations, focusing on privacy and security concerns. While the proposed BEST-LPHR solution cannot, expectedly, address all problems in LPHR, this prototype aims to increase EHR adoption rate and reduce LPHR implementation roadblocks. In a long run, the BEST-LPHR will contribute to improving health care efficiency and the quality of life for many patients. / Doctor of Philosophy / Longitudinal personalized electronic health record (LPHR) provides a holistic view of health records for individuals and offers a consistent patient-controlled information system for managing the health care of patients.

Memory corruption attacks have existed in C and C++ for more than 30 years, and over the years many defenses have been proposed. In addition to that, a new class of attacks, Spectre, has emerged that abuse speculative execution to leak secrets and sensitive data through micro-architectural side channels. Many defenses have been proposed to mitigate Spectre as well. However, with every new defense a new attack emerges, and then a new defense is proposed. This is an ongoing cycle between attackers and defenders. There exists many defenses for many different attack avenues. However, many suffer from either practicality or effectiveness issues, and security researchers need to balance out their compromises. Recently, many hardware vendors, such as Intel and ARM, have realized the extent of the issue of memory corruption attacks and have developed hardware security mechanisms that can be utilized to defend against these attacks. ARM, in particular, has released a mechanism called Pointer Authentication in which its main intended use is to protect the integrity of pointers by generating a Pointer Authentication Code (PAC) using a cryptographic hash function, as a Message Authentication Code (MAC), and placing it on the top unused bits of a 64-bit pointer. Placing the PAC on the top unused bits of the pointer changes its semantics and the pointer cannot be used unless it is properly authenticated. Hardware security features such as PAC are merely mechanisms not full fledged defences, and their effectiveness and practicality depends on how they are being utililzed. Naive use of these defenses doesn't alleviate the issues that exist in many state-of-the-art software defenses. The design of the defense that utilizes these hardware security features needs to have practicality and effectiveness in mind. Having both practicality and effectiveness is now a possible reality with these new hardware security features. This dissertation describes utilizing hardware security features, namely ARM PAC, to build effective and practical defense mechanisms. This dissertation first describes my past work called PACTight, a PAC based defense mechanism that defends against control-flow hijack- ing attacks. PACTight defines three security properties of a pointer such that, if achieved, prevent pointers from being tampered with. They are: 1) unforgeability: A pointer p should always point to its legitimate object; 2) non-copyability: A pointer p can only be used when it is at its specific legitimate location; 3) non-dangling: A pointer p cannot be used after it has been freed. PACTight tightly seals pointers and guarantees that a sealed pointer cannot be forged, copied, or dangling. PACTight protects all sensitive pointers, which are code pointers and pointers that point to code pointers. This completely prevents control-flow hijacking attacks, all while having low performance overhead. In addition to that, this dissertation proposes Scope-Type Integrity (STI), a new defense policy that enforces pointers to conform to the programmer's intended manner, by utilizing scope, type, and permission information. STI collects information offline about the type, scope, and permission (read/write) of every pointer in the program. This information can then be used at runtime to ensure that pointers comply with their intended purpose. This allows STI to defeat advanced pointer attacks since these attacks typically violate either the scope, type, or permission. We present Runtime Scope-Type Integrity (RSTI). RSTI leverages ARM Pointer Authentication (PA) to generate Pointer Authentication Codes (PACs), based on the information from STI, and place these PACs at the top bits of the pointer. At runtime, the PACs are then checked to ensure pointer usage complies with STI. RSTI overcomes two drawbacks that were present in PACTight: 1) PACTight relied on a large external metadata for protection, whereas RSTI uses very little metadata. 2) PACTight only protected a subset of pointers, whereas RSTI protects all pointers in a program. RSTI has large coverage with relatively low overhead. Also, this dissertation proposes sPACtre, a new and novel defense mechanism that aims to prevent Spectre control-flow attacks on existing hardware. sPACtre is an ARM-based defense mechanism that prevents Spectre control-flow attacks by relying on ARM's Pointer Authentication hardware security feature, annotations added to the program on the secrets that need to be protected from leakage and a dynamic tag-based bounds checking mechanism for arrays. We show that sPACtre can defend against these attacks. We evaluate sPACtre on a variety of cryptographic libraries with several cryptographic algorithms, as well as a synthetic benchmark, and show that it is efficient and has low performance overhead Finally, this dissertation explains a new direction for utilizing hardware security features to protect energy harvesting devices from checkpoint-recovery errors and malicious attackers. / Doctor of Philosophy / In recent years, cyber-threats against computer systems have become more and more preva- lent. In spite of many recent advancements in defenses, these attacks are becoming more threatening. However, many of these defenses are not implemented in the real-world. This is due to their high performance overhead. This limited efficiency is not acceptable in the real-world. In addition to that, many of these defenses have limited coverage and do not cover a wide variety of attacks. This makes the performance tradeoff even less convincing. Thus, there is a need for effective and practical defenses that can cover a wide variety of attacks. This dissertation first provides a comprehensive overview of the current state-of-the-art and most dangerous attacks. More specifically, three types of attacks are examined. First, control-flow hijacking attacks, which are attacks that divert the proper execution of a pro- gram to a malicious execution. Second, data oriented attacks. These are attacks that leak sensitive data in a program. Third, Spectre attacks, which are attacks that rely on sup- posedly hidden processor features to leak sensitive data. These "hidden" features are not entirely hidden. This dissertation explains these attacks in detail and the corresponding state-of-the-art defenses that have been proposed by the security research community to mitigate them. This dissertation then discusses effective and practical defense mechanisms that can mitigate these attacks. The dissertation discusses past work, PACTight, as well as its contributions, RSTI and sPACtre, presenting the full design, threat model, implementation, security eval- uation and performance evaluation of each one of these mechanisms. The dissertation relies on insights derived from the nature of the attack and compiler techniques. A compiler is a tool that transforms human-written code into machine code that is understandable by the computer. The compiler can be modified and used to make programs more secure with compiler techniques. The past work, PACTight, is a defense mechanism that defends against the first type of attacks, control-flow hijacking attacks, by preventing an attacker from abusing specific code in the program to divert the program to a malicious execution. Then, this dissertation presents RSTI, a new defense mechanism that overcomes the limitations of PACTight and extends it to cover data oriented attacks and prevent attackers from leaking sensitive data from the program. In addition to that, this dissertation presents sPACtre, a novel defesnse mechanism that defends against Spectre attacks, and prevents an attacker from abusing a processor's hidden features. Finally, this dissertation briefly discusses a possible future direction to protect a different class of devices, referred to as energy-harvesting devices, from attackers.

Yes / Internet of Things (IoT) platforms are responsible for overall data processing in the IoT System. This ranges from analytics and big data processing to gathering all sensor data over time to analyze and produce long-term trends. However, this comes with prohibitively high demand for resources such as memory, computing power and bandwidth, which the highly resource constrained IoT devices lack to send data to the platforms to achieve efficient operations. This results in poor availability and risk of data loss due to single point of failure should the cloud platforms suffer attacks. The integrity of the data can also be compromised by an insider, such as a malicious system administrator, without leaving traces of their actions. To address these issues, we propose in this work an edge-based blockchain enabled anomaly detection technique to prevent insider attacks in IoT. The technique first employs the power of edge computing to reduce the latency and bandwidth requirements by taking processing closer to the IoT nodes, hence improving availability, and avoiding single point of failure. It then leverages some aspect of sequence-based anomaly detection, while integrating distributed edge with blockchain that offers smart contracts to perform detection and correction of abnormalities in incoming sensor data. Evaluation of our technique using real IoT system datasets showed that the technique remarkably achieved the intended purpose, while ensuring integrity and availability of the data which is critical to IoT success. / Petroleum Technology Development Fund(PTDF) Nigeria, Grant/Award Number:PTDF/ED/PHD/TYM/858/16

The concept of BIM is nascent but evolving rapidly, thus, its deployment has become the latest shibboleth amongst both academics and practitioners in the construction sector in the recent couple of years. Due to construction clients buy-in of the BIM concept, the entire industry is encouraged to pursue a vision of changing work practices in line with the BIM ideas. Also, existing research recognises that the implementation of BIM affects all areas of the construction process from design of the building, through the organisation of projects, to the way in which the construction process is executed and how the finished product is maintained. The problem however is that, existing research in technology utilisation in general, and BIM literature in particular, has offered limited help to practitioners trying to implement BIM, for focusing predominantly, on technology-centric views. Not surprisingly therefore, the current BIM literature emphasises on topics such as capability maturity models and anticipated outcomes of BIM rollouts. Rarely does the extant literature offer practitioners a cohesive approach to BIM implementation. Such technology-centric views inevitably represent a serious barrier to utilising the inscribed capabilities of BIM. This research therefore is predicated on the need to strengthen BIM implementation theory through monitoring and analysing its implementation in practice. Thus, the focus of this thesis is to carry out a sociotechnical systems (STS) analysis of BIM implementation in construction organisations. The concept of STS accommodates the dualism of the inscribed functions of BIM technologies and the contextual issues in the organisations and allows for the analysis of their interactive combination in producing the anticipated effect from BIM appropriation. An interpretive research methodology is adopted to study practitioners through a change process, involving the implementation of BIM in their work contexts. The study is based on constructivist ontological interpretations of participants. The study adopts an abductive research approach which ensures a back-and-forth movement between research sites and the theoretical phenomenon, effectively comparing the empirical findings with the existing theories and to eventually generate a new theoretical understanding and knowledge regarding the phenomenon under investigation. A two-stage process is also formulated for the empirical data collection - comprising: 1) initial exploratory study to help establish the framework for analysing BIM implementation in the construction context; and 2) case studies approach to provide a context for formulating novel understanding and validation of theory regarding BIM implementation in construction organisations. The analysis and interpretation of the empirical work follows the qualitative content analysis technique to observe and reflect on the results. The findings have shown that BIM implementation demands a complete breakaway from the status quo. Contrary to the prevailing understanding of a top-down approach to BIM utilisation, the study revealed that different organisations with plethora of visions, expectations and skills combine with artefacts to form or transform BIM practices. The rollout and appropriation of BIM occurs when organisations shape sociotechnical systems of institutions, processes and technologies to support certain practices over others. The study also showed that BIM implementation endures in a causal chain of influences as different project organisations with their localised BIM ambitions and expectations combine to develop holistic BIM-enabled project visions. Thus, distributed responsibilities on holistic BIM protocols among the different levels of influences are instituted and enforced under binding contractual obligations. The study has illuminated the centrality of both the technical challenges and sociological factors in shaping BIM deployment in construction. It is also one of the few studies that have produced accounts of BIM deployment that is strongly mediated by the institutional contexts of construction organisations. However, it is acknowledged that the focus of the research on qualitative interpretive enquiry does not have the hard and fast view of generalising from specific cases to broader population/contexts. Thus, it is suggested that further quantitative studies, using much larger data sample of BIM-enabled construction organisations could provide an interesting point of comparison to the conclusions derived from the research findings.

<p>FRET-enabled optical computing is a new computing paradigm that uses the energy of incident photons to perform computation in molecular-scale circuits composed of inter-communicating photoactive molecules. Unlike conventional computing approaches, computation in these circuits does not require any electric current; instead, it relies on the controlled-migration of energy in the circuit through a phenomenon called Förster Resonance Energy Transfer (FRET). This, coupled with other unique features of FRET circuits can enable computing in new domains that are unachievable by the conventional semiconductor-based computing, such as in-cell computing or targeted drug delivery. In this thesis, we explore novel FRET-based multiplexing techniques to significantly increase the storage density of optical storage media. Further, we develop analysis algorithms, and computer-aided design tools for FRET circuits.</p><p>Existing computer-aided design tools for FRET circuits are predominantly ad hoc and specific to particular functionalities. We develop a generic design-automation framework for FRET-circuit optimization that is not limited to any particular functionality. We also show that within a fixed time-budget, the low-speed of Monte-Carlo-based FRET-simulation (MCS) algorithms can have a potentially-significant negative impact on the quality of the design process, and to address this issue, we design and implement a fast FRET-simulation algorithm which is up to several million times faster than existing MCS algorithms. We finally exploit the unique features of FRET-enabled optical computing to develop novel multiplexing techniques that enable orders of magnitude higher storage density compared to conventional optical storage media, such as DVD or Blu-Ray.</p> / Dissertation

Thesis (MBA (Business Management))--Stellenbosch University, 2008. / ENGLISH ABSTRACT: The purpose of this study is to investigate the awareness of spiritual intelligence in the NGO sector. The study attempts to define the concepts of meaning, spirituality, spiritual intelligence and spiritual leadership. The research used as its basis questionnaires by Katz (2007) derived from the Zohar and Marshall characteristics of Spiritual Intelligence. A recent Gallup Poll showed that 45 percent of Americans talk about their faith at work, and this suggests that employers should not dismiss its motivating power. For most people faith and spirituality is a private matter. One can therefore pose the question, “What has the 'spirituality' of employees got to do with big business?” However, when the HR directors of Nokia, Unilever, McKinsey, Shell, Coca-Cola, Hewlett Packard, Merck Pharmaceuticals, Starbucks and the Cooperative Bank, some of the world's most successful companies talk about concepts such as 'spiritual quotient' and 'spiritual capital' one otherwise has to sit up and listen. Sir John Templeton, founder of the John Templeton Foundation, spends $16 million to $30 million a year funding research that explores links between science and God. He suggests that "No human being has yet even understood 1 percent of what can be learned about spiritual matters". It is initiatives like these and the growing number of professional presentations, journal articles, books and conferences devoted to the subject that confirms the new interest in spirituality. It seems that a consensus is emerging on the principal elements of spirituality for working people, which includes acknowledging God, the importance of prayer, other people and a sustainable world. Research further suggests that spirituality enables a businessperson to gain a more integrated perspective on their firm, family, neighbours, community and on themself. Sweeping social and economical changes, including downsizing, mergers, globalisation, the threat of terrorism since the 9/11 attacks, and corporate ethical scandals are all contributing to business’s spiritual awakening. In order to cope with increased stress and alienation, both managers and employees seek meaning and purpose in the workplace. The research in this study suggests that amidst these changes and associated challenges, there exists a high level of spiritual awareness in the organisations and the managers that participated in this study. The study report provides research examples and references to other case studies from across the world, including practical guidance for implementing and measuring workplace spirituality. The conclusions suggest that spirituality is a not passing fad but, an authentic movement based on universal spiritual principles. / AFRIKAANSE OPSOMMING: Die doel van hierdie studie is om die bewustheid van geestelike intelligensie in die nie-regeringsorganisasie- (NRO-) sektor te ondersoek. Hierdie studie probeer die konsepte betekenis, spiritualiteit, geestelike intelligensie en geestelike leierskap definieer. Die navorsing het as grondslag die vraelyste van Katz (2007) gebruik, wat ontleen is aan die eienskappe van geestelike intelligensie soos gedefinieer deur Zohar en Marshall. ’n Onlangse Gallup-opname het getoon dat 45 persent van Amerikaners by die werk oor hulle geloof praat, en dit impliseer dat werkgewers geloof as motiveringskrag nie moet onderskat nie. Vir die meeste mense is geloof en spiritualiteit ’n persoonlike saak. ’n Mens kan dus vra: Wat het die ‘spiritualiteit’ van werknemers met groot sakeondernemings te make? Wanneer die menslikehulpbron-direkteure van Nokia, Unilever, McKinsey, Shell, Coca-Cola, Hewlett Packard, Merck Pharmaceuticals, Starbucks en die Co-operative Bank, ’n paar van die wêreld se suksesvolste maatskappye, egter praat oor konsepte soos ‘spirituele kwosiënt’, moet ’n mens goed na hulle luister. Sir John Templeton, stigter van die John Templeton Foundation, spandeer elke jaar tussen $16 miljoen en $30 miljoen om geld te voorsien vir navorsing wat die verband tussen die wetenskap en God ondersoek. Hy stel voor: “Geen menslike wese het nog ooit eens een persent verstaan van wat oor geestelike sake ontdek kan word nie.” Dit is inisiatiewe soos hierdie, sowel as die groeiende aantal professionele aanbiedings, tydskrifartikels, boeke en konferensies wat aan hierdie onderwerp gewy word, wat die nuwe belangstelling in spiritualiteit bevestig. Dit lyk of daar konsensus begin ontstaan oor die hoofelemente van spiritualiteit vir werkende mense, wat insluit die erkenning van God, en die belangrikheid van gebed, ander mense en ’n volhoubare wêreld. Navorsing impliseer verder dat spiritualiteit sakepersone in staat stel om ’n meer geïntegreerde perspektief op hulle firma, familie, bure, gemeenskap en hulleself te kry. Ingrypende sosiale en ekonomiese veranderinge, insluitende afskaling, samesmeltings, globalisering, die bedreiging van terrorisme sedert die aanvalle op 11 September 2001 en etiese skandale in die korporatiewe wêreld, dra by tot maatskappye se spirituele ontwaking. Om die toenemende spanning en vervreemding te kan hanteer, soek sowel bestuurders as werknemers na betekenis en doelgerigtheid in die werkplek. Die navorsing van hierdie studie impliseer dat daar te midde van hierdie veranderinge en meegaande uitdagings ’n hoë vlak van spirituele bewustheid heers in die organisasies en die bestuurders wat aan hierdie studie deelgeneem het. Dié studieverslag voorsien navorsingvoorbeelde en verwysings na ander gevallestudies van oor die hele wêreld heen, insluitende praktiese riglyne om spiritualiteit in die werkplek te vestig en te meet. Die gevolgtrekkings impliseer dat spiritualiteit nie net ’n verbygaande gier is nie, maar ’n outentieke beweging gegrond op universele geestelike beginsels.

The reason for the study is that IT-enabled organizational change processes such as information system implementations have high costs and disappointing results. Studies to identify causes of the mentioned failures are mainly based on a variance approach. This study applies another approach which is not yet performed in this field of research and affects several themes. Based on a process approach data is compared with ideal-process theories to identify the generative mechanisms causing the unfolding of the process. Thus, the study identifies a recipe and not the ingredients.
