Abstract:
The main purpose was to evaluate the in vitro adhesion strength of direct and semi-direct composite resin restorations in dentin, when the same adhesive system is applied, using microtensile testing (μTBS) and to observe the most recurrent types of failure in the different groups. For this study, 16 intact human mandibular molars without microscopic evidence of lesions were randomly divided into two test groups, according to the restoration strategy: direct restoration (DR) and semi-direct restoration (SR). For both restorative strategies, the same adhesive system (Clearfil SE Bond 2, Kuraray, Tokyo, Japan) was applied to the dentin surface using a two-step self-etching approach with no prior conditioning of the dentin, and the same composite resin (Ceram. x Sepctra ST HV, Dentsply Sirona, Charlotte, NC, USA) was used as a restorative material. The indirect restoration was cemented using resin cement (Variolink Esthetic LC, Ivoclar Vivadent, Schaan, Liechtenstein) within the interior side of the restoration. Each specimen was sliced into sections measuring approximately 1 mm2. The rods were then subjected to a microtensile bond strength test and the statistical analysis on the differences in μTBS between the groups were determined with the Mann–Whitney test. The surfaces were examined to determine the failure mode. The Chi-Square test was used to determine the association between the type of restoration and the failure mode. The DR group presented with a mean μTBS of 38.15 ± 10.75 MPa and a predominance of cohesive failures in the composite resin (69.5%). The SR group showed a mean μTBS of 25.45 ± 10.19 MPa and a predominance of adhesive failures (92.3%). There was not only a statistically significant difference in the adhesive strength of the DR and SR groups (p < 0.001), but also a statistically significant association between the type of restorative strategy and failure mode (p < 0.001). Even though Clearfil SE Bond 2 provided acceptable adhesion to the dentin, using the same two-step self-etch adhesive system, lower adhesive strength and more adhesive failures are expected in semi-direct restorations when compared to direct restorations.

Abstract:
Aim. To assess the bond strength of composite material to ceramic surface of metal-ceramic-fixed dental prosthesis depending on the type of restoration systems used for chipped porcelain restorations. Methods. Bond strength of restoration material to porcelain coating surface were studied according to ISO 10477 issued at 01.10.2004. The surface of the ceramic-metal plates was polished by different methods depending on the restoration system used. Restorative material was applied using a template. Prepared samples were placed in a testing machine and loaded at a constant crosshead speed of 1±0.3 mm/min before separation, the load F at break was registered by an automatic recorder. Results. Similar bond strength results were revealed for restoration systems not requiring acid pickling of porcelain surface («Cimara», «Ceramic Repair») and restoration system including 9.5% hydrofluoric acid «Porcelain etch silane»: 17.993, 17.774 and 17.896 MPa respectively. Bond strength was much higher (25.278 MPa) if restoration system with 4% hydrofluoric acid was used. «Vertise™ Flow» restorative single-component material also provided significant bond strength - 24.315 MPa. Conclusion. The study showed the possibility of using a single-component restorative material to repair chipped porcelain tile coating metal-ceramic-fixed dental prostheses. For longer life of chipped porcelain tile coating restoration of dental prostheses, the use of restoration systems including 4% hydrofluoric acid is recommended.

Abstract:
This paper propose an intelligent restoration aid system that assists the decision of power system operators for reliable and fast restoration processes when a blackout happened in massive power systems. This system consists of a topology processor and intelligent restoration aid system. The topology processor identifies the real-time embedded topology structure between power system facilities and determines the power outage section. The power system restoration aid system determines the feasible restoration path in terms of overloads and real power flow. Case studies demonstrate a promising possibility of practical application.

Abstract:
The hassle to reproduce proximal anatomic contour in a restoration is one of the most common challenges faced by the clinicians while managing anterior spacing. The presence of open gingival area or black triangle involving social six would further complicate the situation to be managed with a direct restoration, provided the clinician has a guide to precisely reproduce the anatomic surfaces. The use of Bioclear matrix system prevails as an ideal choice for the dentists to accomplish long lasting, stronger and aesthetically superior composite restorations. This case report aims to exhibit the benefits of using Bioclear matrix in the restorative management of anterior spacing and its role in achieving clinically and functionally superior restoration with suitable biological properties.

Abstract:
ABSTRACT Bulk Fill Composite resins are restorative materials that present low tension and polymerization shrinkage, allowing them to be inserted in a single increment of up to 4 mm of thickness, in a restorative cavity. This paper aims to report a clinical case of restorations done on posterior teeth with Bulk Fill restorative system, using selective acid-etching with self-etch adhesive system. Patient, male, 24 years old, presented a carious lesion on the occlusal surface of dental element 37 and an occlusal unsatisfactory amalgam restoration, on element 36. A restorative treatment with Universal Bond 3M / ESPE and bulk fill composite resin (3M / ESPE) was done. According to the case described, it was possible to observe that the materials and techniques used restored the form and function of the teeth involved, preserving pulp vitality with a satisfactory aesthetic result. The bulk fill resins employed offer practicality and decrease clinical time, with satisfactory clinical applicability in the aesthetic and functional rehabilitation of posterior teeth.

SUMMARY Objective The aim of this study was to evaluate the clinical performance of a glass ionomer restorative system compared with a microfilled hybrid posterior composite in a four-year randomized clinical trial. Methods A total of 140 (80 Class 1 and 60 Class 2) lesions in 59 patients were either restored with a glass ionomer restorative system (Equia, GC, Tokyo, Japan), which was a combination of a packable glass ionomer (Equia Fil, GC) and a self-adhesive nanofilled coating (Equia Coat, GC), or with a microfilled hybrid composite (Gradia Direct Posterior, GC) in combination with a self-etch adhesive (G-Bond, GC) by two experienced operators according to the manufacturer's instructions. Two independent examiners evaluated the restorations at baseline and at one, two, three, and four years postrestoration according to the modified US Public Health Service criteria. Polyvinyl siloxane impression negative replicas at each recall were observed under scanning electron microscopy (SEM) to evaluate surface characteristics. The statistical analyses were carried out with McNemar, Pearson Chi-square, and Cochran Q- tests (p<0.05). Results After four years, 126 (76 Class 1 and 50 Class 2) restorations were evaluated in 52 patients, with a recall rate of 88.1%. None of the restorations showed trends to downgrade in anatomical form, secondary caries, surface texture, postoperative sensitivity, and color match (p>0.05). Significant differences in marginal adaptation and discoloration were found at four years compared to baseline for both restorative materials for Class 1 and Class 2 restorations (p<0.05). Only one Class 2 Equia restoration was missing at three years (3.9%), and another one was missing at four years (7.7%) (p>0.05). SEM evaluations were in accordance with the clinical findings. Conclusions The use of both materials for the restoration of posterior teeth exhibited a similar and clinically successful performance after four years.

Full text
Abstract:
In this paper, a power system restoration study following a massive or complete blackout was performed. The power system restoration process from a complete shutdown system without the operating generation and load starts with energizing primary restorative transmission systems. During this primary restoration process, unexpected over-voltage may occur due to nonlinear interaction between the unloaded transformer and the transmission system. This is known as the harmonic resonance phenomenon that may cause the burning out of a transformer or other devices. So far, harmonic resonances have been reported in some extra-high voltage systems around the world. Since the harmonic resonance originates from the nonlinear characteristics of the power system components, it is very difficult to predict the occurrence of this phenomenon. This paper reports the analyses of the harmonic resonance that can occur in the Korean power system. In addition, through calculating the required buffer load compared to the length of the line, a solution that changes the length of the restoration path impedance considering the specificity of the Korean system was presented. The various analyses of harmonic overvoltage, including methodologies that are used internationally as comparison groups, are provided based on PSCAD/EMTDC simulations.

Abstract:
This paper illustrates the relation between resilience and water system serviceability, and the dependence of community resilience on water system resilience. Five normally provided water system service categories are defined: water delivery, quality, quantity, fire protection, and functionality. Water system performances are described in terms of how these services are provided to customers after an earthquake in relation to pre-earthquake services. The important distinction between system operability and functionality is defined. The characteristics of each service restoration and how they interact are explained. A case study from the Los Angeles Water System is presented to show applicability of the five service categories in actual post-earthquake restorations. The examined service restoration features can be used as engineering and management principles to improve overall service restoration. Some strategies for improving post-earthquake services and their restorations are presented in the context of the five service categories. Reviewing the five water service categories identifies how water system resilience is more complex than previously recognized.

Abstract:
Introduction: Mercury is a heavy metal and overexposure to mercury may have a toxic effect on the nervous system, renal system, reproductive system, immune system and on motor activity. In dentistry, mercury is used along with metals in amalgam restorations. Studies have shown that mercury consistently releases from amalgam restorations. There is a controversy regarding this released mercury having any toxic effect on human beings. The aim: The aim of this work was to highlight the adverse effect of silver amalgam restoration and create awareness among all. Conclusion: Amalgam is still widely used as restorative material due to its excellent physical properties. Because of its environmental impact, mercury must be kept away from all users, including dentistry.

Abstract:
Computer-aided design and manufacturing technology has been closely associated with implant-supported restoration. The digital system employed for prosthodontic restorations comprises data acquisition, processing, and manufacturing using subtractive or additive methods. As digital implantology has developed, optical scanning, computer-based digital algorithms, fabricating techniques, and numerical control skills have all rapidly improved in terms of their accuracy, which has resulted in the development of new ceramic materials with advanced esthetics and durability for clinical application. This study reviews the application of digital technology in implant-supported dental restoration and explores two globally utilized ceramic restorative materials: Yttria-stabilized tetragonal zirconia polycrystalline and lithium disilicate glass ceramics.

Thesis (S.M.)--Massachusetts Institute of Technology, System Design and Management Program, 2008.<br>Includes bibliographical references.<br>In this thesis, we have developed an extensive study to evaluate image restoration from a single image, colored or monochromatic. Using a mixture of Gaussian and Poisson noise process, we derived an objective function to estimate the unknown object and point spread function (psf) parameters. We have found that, without constraint enforcement, this blind deconvolution algorithm tended to converge to the trivial solution: delta function as the estimated psf and the detected image as the estimated object. We were able to avoid this solution set by enforcing a priori knowledge about the characteristics of the solution, which included the constraints on object sharpness, energy conservation, impulse response point spread function solution, and object gradient statistics. Applying theses constraints resulted in significantly improved solutions, as evaluated visually and quantitatively using the distance of the estimated to the true function. We have found that the distance of the estimated psf was correlated better with visual observation than the distance metric using the estimated object. Further research needs to be done in this area. To better pose the problem, we expressed the point spread function as a series of Gaussian basis functions, instead of the pixel basis function formalism used above. This procedure has reduced the dimensionality of the parameter space and has resulted in improved results, as expected. We determined a set of weights that yielded optimum algorithm performance.<br>(cont.) Additional research needs to be done to include the weight set as optimization parameters. This will free the user from having to adjust the weights manually. Of course, if certain knowledge of a weight is available, then it may be better to start with that as an initial guess and optimize from there. With the knowledge that the gradient of the object obeys long-tailed distribution, we have incorporated a constraint using the first two moments, mean and variance, of the gradient of the object in the objective function. Additional research should be done to incorporate the entire distribution in the objective and gradient functions and evaluate the performance.<br>by Jean J. Dolne.<br>S.M.

Abstract:
This thesis contributes to the power system restoration (PSR) field by studying (in the aim of improving) the power system repair and restoration (PSRR) which is a novel problem in PSR. The optimisation concept was our approach and mechanism in tackling this topic. The thesis provides a basic contribution to the PSRR field by studying some of its main subjects and presenting improvements to the best practices in the field. This thesis is built on five research papers related to the thesis title. The thesis investigated a large number of high-quality published research papers, and presented a novel, precise, and comprehensive overview of the topic that could be considered a good introduction for anyone who would like to learn the topic. This was presented in chapter two. We have presented a well-developed and easy to understand structure that starts from the basics of PSR and PSRR to their details and relevant subjects. Also, in this thesis we provided application-based studies using mathematical optimisation techniques, where we model a specific power system then solve the PSRR problem aiming optimality. Different optimisation techniques were applied, analysed, and compared for both sides of the problem (i.e. the restoration problem, and the repair problem) as well as different modelling for power systems. Our findings in this chapter were interesting and align with other high-quality studies in the literature. This was presented in details in chapter three. This thesis also tackled a very important relevant subject which is the system reliability under certain restoration scenarios. Where we studied the effects of restoration actions under certain conditions such as cold load pickup events to the reliability indices of the system. A novel Nature-inspired optimisation technique was developed and compared to an old technique that was presented in a high-quality study in the literature. This was presented in chapter four. We concluded this thesis research by developing a statistical analysis for power system outages for a decade period of time in the Australian industry as well as investigating the potential benefits of smart grid technologies and their investments to the power grid. Many statistical methods were applied and investigated using state-of-the-art programming tools. This was presented in chapter five. We have presented very interesting results and findings in this chapter.

Dissertação para obtenção do Grau de Mestre em Engenharia do Ambiente, Perfil de Engenharia de Sistemas Ambientais<br>The purpose of this thesis is to provide river basin managers with a framework for river restoration. To that end, it presents and discusses the relevant information on the current condition of the river Tua, in northern Portugal, and establishes what can be done to restore the river basin in order to protect the most important drainage basin's functions and ecosystems. It is intended that this thesis will serve as an example of the application of current knowledge on freshwater restoration which can be emulated by future managers in their efforts to restore this, or any water body they wish to. To this purpose, the thesis analyzes demographic data on the municipalities of the Tua drainage basin. It discusses literature and research on the subject of river restoration and important river processes in the following chapter, so as to introduce important theory concepts to have in mind when designing any restoration efforts. In its methodology, the techniques and data assessment tools used in the process of evaluating the river basin's conditions are described and defined, allowing interested managers to review and adapt to the specific needs of drainage basins anywhere. Finally, it presents a practical point-of-view intended to be applied on other freshwater bodies. The thesis includes the realization of an assessment physical characteristics and status of the Tua river reach, it splits up the drainage basin into several different sub-basins, for individual study, and, after a discussion of the conclusions drawn from the assessment for the whole drainage basin, it presents arguments for choosing the sub-sections which present the highest risk to the drainage basin and, as such, require priority action. This section also includes a presentation of the arguments in support of specific techniques to be put into place, given the specific needs of the sub-basin and the restoration goals for the entire drainage basin.

Abstract:
This thesis is dedicated to the study of power system restoration planning. Restoration planning is a complex decision and control problem important to the power industry from both practical and theoretical points of view. It involves a wide range of approaches and disciplines. This thesis proposes an integrated methodology for power system restoration planning which incorporates heuristics (e.g. restoration guidelines), algorithms (e.g. load flow, optimization), friendly graphical user interface and data bases.<br>Heuristics provide rules for dividing the power system to be restored into subsystems (each of which is restored independently), for selecting suitable scenarios (sequence of switching operations) from the scenario library, and for creating appropriate scenarios whenever these do not exist in the scenario library.<br>The conventional trial-and-error approach to restoration may easily lead to infeasible restoration scenarios, usually requires a large number of control adjustments and it is slow. On the other hand, the optimization algorithm presented in this thesis can systematically ensure the feasibility of a defined restoration scenario as well as to give an optimal solution for all controllable variables in the sense of minimizing the number of control variable adjustments from stage to stage. The optimization algorithm, therefore, reduces the duration of the restoration procedure which is a critical consideration during power system blackouts.<br>The interactive graphics man-machine interface (MMI) greatly facilitates the creation of restoration plans directly on the dynamic diagram of the network as well as displaying simulation and optimization results. Through the graphics MMI, users can easily sub-divide the grid to be restored into sub-networks, request the execution of simulation programs such as finding available paths from generation to load for energization purposes, define and modify scenarios of switching sequences, and execute the scenario optimization. Users can also test a restoration plan interactively with a load flow simulator.<br>Data bases contain the graphical representation of power systems and their numerical data. They also contain numerical data for the simulation programs. With the data base, users can easily store and retrieve power system networks on which the restoration process is simulated. In the data base, there also exists a scenario library which stores all pre-defined restoration scenarios. These restoration scenarios can be retrieved for later study.<br>The optimization algorithm and graphical user interface were extensively tested by creating and simulating numerous and restoration scenarios on actual networks. The results show that the graphical user interface is powerful and useful. In addition, the optimization algorithm not only provides a systematic way to find feasible solutions for restoration (usually very difficult with a trial-and-error approach) but also greatly reduces the duration of the restoration process.

Abstract:
The process of Synchronization between two buses in a power system plays a vital role, especially during blackstart or bulk power system restoration period. The synchronization process is primarily monitored in the presence of experienced personnel at the substation level, which might not control or even predict the after effects of synchronization as soon as the synchronizing breaker between the two buses respective to the two islands is closed. However, with the advent of phasor measurement units (PMUs) providing time synchronized synchrophasor data, synchroscope functionality can now be implemented at a centralized remote control platform, usually the control room of the specific utility. This thesis presents a technique along with the actual implementation of such a PMU Synchroscope analytic developed as a part of the Department of Energy sponsored open and Extensible Control and Analytics platform for synchrophasor data (openECA project). The challenges faced to realize this functionality at the centralized remote location along with methods to overcome these hurdles have been discussed in the document. Additional features in comparison to the conventional synchroscope device are also added to facilitate a smoother and successful synchronization, reducing error on behalf of the user /operator and thus, facilitating a faster power system restoration.<br>Master of Science<br>Successful and proper synchronization between different nodes of a power system is one of the most crucial stages of restoring power after a major wide area electricity outage. Improper synchronization may lead to additional system outages and might delay the restoration process. In this regards, it is desired to perform this vital task at the electric utility’s central remote control room. This thesis develops an application to perform the successful reconnection between two nodes of a system overcoming the various challenges and incorporating system delays. The application designed is based on real-time measurements and is integrated with an open source framework platform for ease of the user.

Abstract:
Ecological restoration is the practice of assisting the recovery of a degraded, damaged or destroyed ecosystem. The aim of this study was to analyse the effects of two different restoration techniques on instream bryophyte abundance, species richness and diversity as well as community composition, in streams channelized for timber-floating. Instream bryophytes were collected from 10 tributaries of the Vindel River in boreal northern Sweden, from five stream reaches each of channelized reaches, which had not been restored; reaches restored in the early 2000s, using best-practice techniques; and reaches restored in the early 2000s and then re-restored in 2010 using the new “demonstration” techniques. A multitude of environmental variables were also measured at the sites. Bryophyte abundance was lower in demonstration restored sites than unrestored or best-practice restored sites but no significant difference was found in bryophyte species richness, diversity or species composition. Environmental variables correlated with bryophyte abundance, species richness, diversity and composition largely reflected effects of restoration, and probably the disturbance associated with restoration. Small sediment grain sizes also had a negative effect on species richness. Other environmental variables that influenced bryophyte species composition were the large-scale factors of latitude, longitude and elevation and reach-scale factors of potassium concentration and light absorbance. It is not yet possible to fully evaluate the effectiveness, in terms of bryophyte response, of the new demonstration restoration compared with best-practice since the recovery time between them differs and has not been sufficient. Long-term monitoring of the effects of restoration is needed in order to better evaluate success.

Abstract:
The problem of restoring a constant image distorted by a system of random time-varying impulse response is discussed. The restoration is based on the observed time-varying distorted image during a finite period of time T. Three methods are considered. Restorations based on the average image is considered first. If the observation time T is finite, the system noise remains to play a role. This results in a restoration problem with object-dependent noise. Second, restoration based on the averaged spatial correlation of the image will be introduced. For finite T the result is an image restoration problem which we could not solve. Third, restoration based on a finite number of image frames will be examined in detail. We use an iterative method based on the minimum-variance unbiased estimation. When the frames are uncorrelated, we obtain the result based on using the average image as a statistic. When the frames are correlated but space–time separable, a Karhunen-Loève transformation that decorrelates the frames is used to reduce the computations. Using an example, we show how the restoration error drops as more frames are included. The higher the interframe correlation, the more reduction of restoration error is obtained by using the frame data, compared with the error of restoration based on frame averaging.

Abstract:
This special report identifies metrics (standard and novel) and analytic approaches to developing trajectories and then describes the conceptual process of using those metrics and approaches to develop restoration trajectories to inform adaptive management in salt-marsh systems. We identify the composite time series trajectory (CTST) approach, in which metrics are measured from restoration sites of different ages within a small spatial range, and the retrospective single-site trajectory (RSST) approach, in which the same restoration metrics are measured over time at one restoration site. In all, we assessed the metrics of 39 studies of salt-marsh restoration in the United States between 1991 and 2019.
