La réhabilitation des fonctions dentaires grâce à la pose de prothèses obtenues par CFAO est l’un des enjeux majeur de la dentisterie restauratrice moderne. La qualité de ces prothèses peut être évaluée grâce à la rugosité, correspondant à une composante de l’intégrité de surface (IS), prépondérante en dentisterie. Les travaux de thèse ont pour but l’évaluation et la quantification de l’influence des caractéristiques liées à différents outils usinant la pièce, des matériaux employés ainsi que les paramètres associés au procédé d’usinage sur la rugosité résiduelle. Grâce aux résultats obtenus lors de ces travaux il est montré une influence assez limitée de la vitesse d’avance sur la rugosité, alors que celles liées à la taille de la micro-géométrie de l’outil, à l’orientation outil/prothèse et aux biomatériaux sont plus significatives. Il est aussi démontré l’importance de l’utilisation d’un jeu de paramètres de rugosité, de façon à obtenir un maximum d’informations relatives à la topologie de la surface. Ceci a conduit à la définition d’indicateurs de performance du processus d'usinage pour l’évaluation multi-physique et multi-indicateurs de l’IS. La validation de la démarche par un cas d’application montre qu’une décomposition topologique de la couronne est nécessaire afin de mieux respecter le cahier des charges prothétique et fournir une aide précieuse au praticien ou technicien de laboratoire. Pour un meilleur respect du cahier des charges initial, chaque région topologique peut ainsi : être usinée grâce à des stratégies d’usinage différentes, être évaluée par un jeu de paramètres de rugosité qui lui est propre et subir un post-traitement de polissage, si nécessaire. / The rehabilitation of dental function following the fitting of prostheses obtained by CAD/CAM is one of the major challenges of modern restorative dentistry. The quality of these prostheses can be assessed using roughness, corresponding to a major surface integrity (SI) component in dentistry. This thesis work aims to evaluate and quantify the influence of the characteristics associated with various milling tools, the materials used, and the parameters associated with the milling process on the residual roughness. The achieved results obtained during this work show a rather limited influence of the feedrate on the roughness, whereas those related to the size of the tool micro-geometry, the tool/prosthesis inclination, and the biomaterials are more significant. The importance of using a roughness parameters set in order to obtain a maximum of information relating to the surface topology is also demonstrated. This in turn leads to the definition of machining process performance indicators for the multi-physical and multi-indicator SI evaluation. The validation of the approach through a case study shows that a topological decomposition of the crown is necessary in order to better respect the prosthetic specifications and to provide valuable assistance to the practitioner or the laboratory technician. Each topological region can thus be machined using different machining strategies, be evaluated by a set of its own roughness parameters set, and undergo a post-processing polishing treatment, if necessary.

Supervisory Control and Data Acquisition (SCADA) systems are responsible for automatic control of several critical infrastructures like power grids. An important requirement of SCADA systems is to provide cryptographic protection of its communications. Many key management schemes have been proposed to provide cryptographic protection. But cryptographic modules are seen as more appropriate solution as it provides cryptographic protection of keys. Recently I has proposed a draft standard SCADA cryptographic module(SCM) which provides direct link security. The goal of this research is joint design of a comprehensive key distribution scheme for SCADA systems, and the architecture of simple SCM to support key distribution and mutual authentication of messages exchanged between any two SCADA entities. Furthermore, unlike the I module, our SCM will be transparent to the type of SCADA communication protocol employed, and will not be restricted to the Bump in the Wire (BITW) mode of operation.

Yes / The paper addresses the problem of pursuing ethical business practices purely under the aegis of ‘integrity’, as frequently used to characterise morally desirable traits. Drawing on the work of philosopher Thomas Kasulis, the paper pairs ‘integrity’ with ‘intimacy’ as a critical concept, placing greater attention upon relational properties, helping to understand ethics as existing between individuals, things and the environment. The argument is that by paying careful attention to spatial and temporal dynamics and proximities of exchange, businesses can better maintain and extend practices of integrity. It reminds us that ethics are developmental (not transcendental); that the cultivation of ethics provides greater depth and ownership and pertains to matters of the body and habits. The paper contributes a way of reading exchanges in the marketplace beyond prescriptive accounts of integrity. Through the lens of both integrity and intimacy, it identifies how we actually ‘live’ or practice greater responsiveness to exchanges.

Educational leaders, families, and politicians debate the methods for teaching, the materials taught, and the content learned (Benninga, Berkowitz, Kuehn, and Smith, 2006; Kohn, 1997). These stakeholders all agree, however, that a major goal for education is to produce learned, productive members of society (DeRoche and Williams, 2001). The goal of this research is to develop a framework that provides schools and division-level leaders with essential elements to resolve character education issues and to provide the means for implementing and evaluating those programs. I used the Delphi research method to collect information from notable researchers and practitioners in the educational world (Keeney, McKenna, and Hasson, 2010). Many of the panelists were selected because their previous research on character education formed a large part of my literature review in Chapter 2. The practitioners are current superintendents, principals, or program directors in representative school systems. The study itself consisted of three rounds of questionnaires; the first round consisted of three open-ended questions that then elicited responses on which the other two rounds were based. The panelists indicated that clearly defined goals and values, stakeholder buy-in, and inclusion of social/emotional issues were the essential elements needed for an effective character education program. Shared responsibilities by stakeholders and student-driven debates were seen as the keys to implementing said program. Finally, the panelists concurred that attendance and discipline data and surveys were the best tools/methods for evaluating character education programs. / Ed. D.

Leader integrity is a virtue and is frequently associated with better company reputation, performance in organizations, and trust from followers. Integrity seems to be a desirable quality an organization leader wants to encompass. Nevertheless, research in implementing integrity for better leadership has been facing quandaries: the ambiguity in referral of integrity domains and definitions, and the dilemma that integrity calls for consistency yet in reality leaders have to be adaptive to cope with changes. In addition, it is not unusual that leaders in various contexts behaving inconsistently yet trust from their followers is retained. Will there be other characteristics that facilitate trust in leaders even if the perceived behavioral integrity (PBI) is low? This research tries to address these leader integrity issues¡Xambiguity, dilemma, and maintenance of trust in order to provide a leader with concrete and concise guidance in implementing integrity. From a perspective of Contractarian coupled with ancient Chinese notions, this research investigates the relationship between a leader¡¦s perceived behavioral integrity and trust from his/her followers and proposes that leaders hold the core¡Xmorality, and work accordingly to identify norms, tackle and solve problems, craft negotiations, yet maintain their awareness in essence. Two core values are identified of moderating effect that a leader with lower PBI is able to maintain a certain level of trust. Should a leader be perceived processing authenticity and righteousness, higher level of trust would be maintained even if he/she were perceived low in behavioral integrity. This research advances the theory of integrity research by clarifying the domains and frees the coercion of consistency issues by proposing a morality-based Contractarian integrity view versus the traditional consistency-based integrity. An empirical attempt to investigate and provide explanation for the phenomena why a leader perceived low in behavioral integrity still obtain trust by their followers is added to the moderated consequences of the framework of integrity research. For practical business practitioners to implement leader integrity, this research suggests they (1) understand the characteristics and domains of integrity, (2) uphold morality and work in harmony with the tides in accordance to the leaders immediate environs, and (3) be salient in authenticity and righteousness. This research believes leader integrity is not merely a personal virtue but a practice that could be learned and implemented. The reward this understanding is better trust from their followers and subordinates.

Advancements in very large scale integration (VLSI) technology have led to unprecedented transistor and interconnect scaling. Further miniaturization by traditional IC scaling in future planar CMOS technology faces significant challenges. Stacking of ICs (3D IC) using three dimensional (3D) integration technology helps in significantly reducing wiring lengths, interconnect latency and power dissipation while reducing the size of the chip and enhancing performance. Interposer technology with ultra-fine pitch interconnections needs to be developed to support the huge I/O connection requirement for packaging 3D ICs. Through vias in stacked silicon ICs and interposers are the key components of a 3D system. The objective of this dissertation is to model through vias in 3D silicon and glass interposers and, to address power and high-speed signal integrity issues in 3D interposers considering silicon biasing effects. An equivalent circuit model of the through via in silicon interposer (Si TPV) has been proposed considering the bias voltage dependent Metal-Oxide-Semiconductor (MOS) capacitance effect. Important design guidelines and optimizations are proposed for Si TPVs used in the signal delivery network, power delivery network (PDN), and as variable capacitors. Through vias in glass interposers (Glass TPVs) are modeled, designed and simulated by using electromagnetic field solvers. Signal and power integrity analyses are performed for silicon and glass interposers. PDN design is proposed by utilizing the MOS capacitance of the Si TPVs for decoupling.

Integrity tests have become a widely used tool in modern-day selection systems. These instruments are generally designed to predict dishonest and counterproductive attitudes/behavior. A group of participants who had quit a job without notice was found to have higher scores on an Integrity/Pessimism scale (indicating low integrity and highly pessimistic attitudes) than an involuntary turnover group of those who had been fired or laid off. Post hoc analyses also found supporting evidence in that the quit without notice group also had higher expressed exit intentions scores (indicating negative attitudes toward current occupation/industry) and shorter average tenure than the involuntary (fired and laid off) group. The potential benefits of developing a predictive Integrity/Pessimism scale are discussed.
