description: We have used ion-irradiation to damage the (001) surfaces of SmB_6 single crystals to varying depths, and have measured the resistivity as a function of temperature for each depth of damage. We observe a reduction in the residual resistivity with increasing depth of damage. Our data are consistent with a model in which the surface state is not destroyed by the ion-irradiation, but instead the damaged layer is poorly conducting and the initial surface state is reconstructed below the damage. This behavior is consistent with a surface state that is topologically protected.

description: Με το πέρασμα των ετών και την εξέλιξη των ανθρωπίνων κοινωνιών, τα δεδομένα χαρακτηρίζονται από έντονες αλλαγές. Ιδίως στη σημερινή εποχή η αλλαγή αποτελεί το κατεξοχήν χαρακτηριστικό του μακρο-περιβάλλοντος. Φυσικά αυτές οι αλλαγές έχουν τεράστιο αντίκτυπο όπως είναι λογικό και στον κόσμο των επιχειρήσεων. Αλλαγές στις οποίες οι επιχειρήσεις καλούνται να απαντήσουν με τη λήψη αποφάσεων ακόμα και αν αυτό σημαίνει την τροποποίηση του τρόπου λειτουργίας των. Σε αυτή την κατεύθυνση τις τελευταίες δεκαετίες έχουν κερδίσει μεγάλο έδαφος νέες πρακτικές στον κόσμο των επιχειρήσεων. Αρχικά την εμφάνιση τους έχουν κάνει κερδίζοντας έδαφος τα κριτήρια ESG, μέσω των οποίων αξιολογείται ο περιβαλλοντικός και κοινωνικός αντίκτυπος των επιχειρήσεων με παράλληλη αξιολόγηση της εσωτερικής τους λειτουργίας. Στο ίδιο μήκος κυμαίνεται και το σύνολο των κανόνων της εταιρικής διακυβέρνησης, οι οποίοι διέπουν τον τρόπο με τον οποίο τα διοικητικά συμβούλια των μεγάλων επιχειρήσεων λαμβάνουν αποφάσεις. Αυτά τα πλαίσια θέτουν κάποια όρια στις επιχειρήσεις, τα οποία δεν πρέπει να υπερβούν καθώς αν συμβεί αυτό μπορεί να επηρεαστεί η αποδοτικότητά τους. Σκοπός της παρούσας εργασίας είναι να εξεταστεί ο βαθμός στον οποίο τα κριτήρια ESG επηρεάζουν την αποδοτικότητα των επιχειρήσεων σε συνδυασμός και με άλλους παράγοντες. Τα αποτελέσματα αναδεικνύουν ότι τα κριτήρια ESG στο σημερινό μακρο-περιβάλλον είναι σε θέση να επηρεάσουν και να βελτιώσουν τη λειτουργία μίας επιχείρησης και κατά συνέπεια την αποδοτικότητά της.
description: With the passage of years and the evolution of human societies, data is characterized by intense changes. Especially in today's era, change is the pre-eminent feature of the macro-environment. Of course, these changes have a huge impact on the business world as well. Changes to which businesses are required to respond by making decisions even if this means modifying the way they operate. In this direction, new practices in the business world have gained a lot of ground in recent decades. Initially, they have made their appearance by gaining ground for the ESG criteria, through which the environmental and social impact of companies is evaluated while evaluating their internal operation. The set of rules of corporate governance, which govern the way in which the boards of directors of large companies make decisions, varies along the same length. These frameworks set certain limits on businesses, which should not be exceeded as their efficiency may be affected if this happens. The purpose of this paper is to examine the extent to which ESG criteria affect the efficiency of companies in combination with other factors. The results show that ESG criteria in today's macro-environment can significantly affect and improve the operation of a company and consequently its efficiency

description: In this paper we propose a mechanism of natural preheating of our universe by introducing an inflaton field dependent mass term for the gravitational wave for a specific class of massive gravity theory. For any single field inflationary model, the inflaton must go through the oscillatory phase after the end of inflation. As has recently been pointed out, if the gravitational fluctuation has inflaton dependent mass term, there will be a resonant amplification of the amplitude of the gravitational wave during the oscillatory phase of inflaton. Because of this large enhancement of the amplitude of the gravitational wave due to parametric resonance, we show that universe can naturally go through the pre-reheated phase with minimally coupled matter field. Therefore, during the reheating phase, there is no need to introduce any arbitrary coupling between the matter field and the inflaton .

description: Low dose hyper-radiosensitivity and induced radioresistance are primarily observed in surviving fractions of cell populations exposed to ionizing radiation, plotted as the function of absorbed dose. Several biophysical models have been developed to quantitatively describe these phenomena. However, there is a lack of raw, openly available experimental data to support the development and validation of quantitative models. The aim of this study was to set up a database of experimental data from the public literature. Using Google Scholar search, 46 publications with 101 datasets on the dose-dependence of surviving fractions, with clear evidence of low dose hyper-radiosensitivity, were identified. Surviving fractions, their uncertainties, and the corresponding absorbed doses were digitized from graphs of the publications. The characteristics of the cell line and the irradiation were also recorded, along with the parameters of the linear-quadratic model and/or the induced repair model if they were provided. The database is available in STOREDB, and can be used for meta-analysis, for comparison with new experiments, and for development and validation of biophysical models.

description: 1. The extracellular matrix (ECM) constitutes the basal lamina and the area between follicular cells. Remodelling the ECM is believed to be a key event in follicular development, especially during selection, and plays an important role in cell migration, survival, and steroidogenesis. miR-199-3p is differentially expressed in the goose granulosa layer during follicular selection and is reported to play a primary role in inhibiting cell migration and invasion. Nevertheless, the effect of miR-199-3p on ovarian follicles and its role in follicular cellular migration is not understood. 2. In this study, qRT-PCR assays revealed that miR-199-3p was differentially expressed in the granulosa layer from goose ovarian follicles before and after follicular selection. Additionally, miR-199-3p overexpression in cultured granulosa cells (GCs) from goose pre-hierarchical follicles significantly suppressed cell viability and migration. It elevated the concentration of progesterone and the expression of key progesterone production genes. Furthermore, miR-199-3p overexpression in the GCs of goose pre-hierarchical follicles inhibited the expression of ECM-related genes (ITGB8, MMP9 and MMP15) yet promoted the expression of another two ECM-related genes (COL4A1 and LAMA1). Finally, dual-fluorescence reporter experiments on 293T cells established the direct targeting of ECM gene ITGB8 by miR-199-3p. 3. In conclusion, miR-199-3p may participate in granulosa cell migration, viability, and steroidogenesis in goose ovarian follicles before selection by modulating ITGB8 and other ECM-related genes.

description: Continuing excavation on the South Acropolis at Azoria in northeastern Crete has exposed buildings of Archaic date (7th-early 5th century b.c.) that served communal or public functions. Work conducted in 2005 and 2006 completed the exploration of Late Archaic levels within the Communal Dining Building (putative andreion complex), the Monumental Civic Building, and the adjacent Service Building. These contexts and their assemblages, especially the animal and plant remains, permit the characterization of diverse dining practices and the interpretation of patterns of food production and consumption. Both the Communal Dining Building and the Monumental Civic Building show extensive evidence of communal feasting and the integration of cult.

description: Most analyses of manipulation of voting schemes have adopted two assumptions that greatly diminish their practical import. First, it is usually assumed that the manipulators have full knowledge of the votes of the nonmanipulating agents. Second, analysis tends to focus on the probability of manipulation rather than its impact on the social choice objective (e.g., social welfare). We relax both of these assumptions by analyzing optimal Bayesian manipulation strategies when the manipulators have only partial probabilistic information about nonmanipulator votes, and assessing the expected loss in social welfare (in the broad sense of the term). We present a general optimization framework for the derivation of optimal manipulation strategies given arbitrary voting rules and distributions over preferences. We theoretically and empirically analyze the optimal manipulability of some popular voting rules using distributions and real data sets that go well beyond the common, but unrealistic, impartial culture assumption. We also shed light on the stark difference between the loss in social welfare and the probability of manipulation by showing that even when manipulation is likely, impact to social welfare is slight (and often negligible).

description: Let $\mathcal{M}$ be a semifinite von Neumann algebra with a faithful, normal, semifinite trace $τ$ and $E$ be a strongly symmetric Banach function space on $[0,τ(1))$. We show that an operator $x$ in the unit sphere of $E\left(\mathcal{M},τ\right)$ is $k$-extreme, $k\in\mathbb N$, whenever its singular value function $μ(x)$ is $k$-extreme and one of the following conditions hold (i) $μ(\infty,x)=\lim_{t\to\infty}μ(t,x)=0$ or (ii) $n(x)\mathcal{M} n(x^*)=0$ and $|x|\geq μ(\infty,x)s(x)$, where $n(x)$ and $s(x)$ are null and support projections of $x$, respectively. The converse is true whenever $\mathcal{M}$ is non-atomic. The global $k$-rotundity property follows, that is if $\mathcal{M}$ is non-atomic then $E$ is $k$-rotund if and only if $E\left(\mathcal{M},τ\right)$ is $k$-rotund. As a consequence of the noncommutive results we obtain that $f$ is a $k$-extreme point of the unit ball of the strongly symmetric function space $E$ if and only if its decreasing rearrangement $μ(f)$ is $k$-extreme and $|f|\geq μ(\infty,f)$. We conclude with the corollary on orbits $Ω(g)$ and $Ω'(g)$. We get that $f$ is a $k$-extreme point of the orbit $Ω(g)$, $g\in L_1+L_{\infty}$, or $Ω'(g)$, $g\in L_1[0,α)$, $α

description: We present a compiler algorithm called Bit Value, which can discover both unused and constant bits in dusty-deck C programs. Bit-Value uses forward and backward dataflow analyses, generalizing constant-folding and dead-code detection at the bit-level. This algorithm enables compiler optimizations which target special processor architectures for computing on non-standard bitwidths.
Using this algorithm we show that up to 31% of the computed bytes are thrown away (for programs from SpecINT95 and Mediabench). A compiler for reconfigurable hardware uses this algorithm to achieve substantial reductions (up to 20-fold) in the size of the synthesized circuits.

description: We investigate the quark-gluon three-point correlation function within a one-loop computation performed in the Curci-Ferrari massive extension of the Faddeev-Popov gauge-fixed action. The mass term is used as a minimal way for taking into account the influence of the Gribov ambiguity. Our results, with renormalization-group improvement, are compared with lattice data. We show that the comparison is in general very satisfactory for the functions which are compatible with chiral symmetry, except for one. We argue that this may be due to large systematic errors {when extracting this function from} lattice simulations. The quantities which break chiral symmetry are more sensitive to the details of the renormalization scheme. We however manage to reproduce some of them with good precision. The chosen parameters allow to simultaneously fit the quark mass function coming from the quark propagator with a reasonably agreement.

Displays of womanhood in the grave: an examination of female social status, roles, and individuality in three cemeteries from early medieval England
Creators: name: Dunn, Caitlyn
Publisher: name: Macquarie University
Year: 2023
Subjects: Other education not elsewhere classified

description: In England, from the 5th through to the early 8th centuries AD, new row-grave cemeteries were used to bury individuals in furnished graves as part of an emerging burial rite. This thesis analyses the female graves of three such cemeteries to investigate displays of female social identity. There are limited historical texts about females contemporary with this period which makes it important to investigate this archaeological evidence. The study of female social identity is also a relatively new area of research because much of modern scholarship has focused on displays of ethnic identity. The cemeteries chosen for this research are Buckland, Kent; Collingbourne Ducis, Wiltshire; and Norton, Cleveland. Osteological analysis has identified a substantial number of female graves at these sites which are the focus of this study. Grave goods such as jewellery and items of dress, knives, weaving and spinning tools, keys, and other artefacts are analysed in order to understand the status, roles, and individuality of females displayed in the grave. This analysis is undertaken with the understanding that the survivors of the deceased chose and placed artefacts in the grave to create a curated display. This research finds that female status was displayed in locally distinctive ways. Status could be displayed using certain dress accessories specific to each community and the artefacts that were prestige items were unique to each cemetery. It also finds that female tasks using knives were emphasised, while duties involving textile production, and household authority were far rarer. Other important roles such as wife and mother were only indirectly displayed at most. Finally, analysis of the types of dress items used in female graves indicated that there were local norms in fashion and varying levels of individuality expressed in the female grave display at each cemetery.
Treatment decision-making in heart failure management
Creators: name: Welch, Sophie
Publisher: name: Imperial College London
Year: 2019

description: Background: Demands for increased patient and public involvement in healthcare has led to changes in policy on decision-making. The shared decision-making (SDM) model is advocated in current health policy and encourages partnership between patients and professionals. Yet limited evidence exists of its effects on clinical outcomes and cost. As a result, a policy-practice divide has emerged. Heart failure management has adopted a more personalised approach to treatment. Yet knowing the treatment that is likely to have the best therapeutic effect does not mean it is right for that individual patient. Patients’ health decisions are influenced by a variety of factors, including their experience of illness and disease beliefs. Professionals need increased understanding of how patients make decisions to support the integration of SDM in to practice. Purpose: This thesis aims to explore different stakeholder perspectives of decision-making in heart failure management and to identify the barriers and facilitators to SDM. Method: A mixed-methods study design involving: Pan-London analyses of multidisciplinary team (MDT) meetings; a qualitative interview study analysed by thematic analysis (Glaser and Strauss, 1967); a Delphi consensus survey. Together these data inform key recommendations to improve communication about treatments and the design of future research. Results: The structures, functions and processes of MDT meetings varied within and across NHS Trusts. Professionals’ assumptions about patient preferences, information needs and approach to decision-making were key barriers to a SDM approach. There was agreement that patients should be involved in treatment decisions, yet there was limited consensus on the priority areas for improvements to practice. Conclusion: Considerable variation exists in the process of treatment decision-making and there is limited concordance between the views of patients, their families and health professionals. Professionals need to tailor their approach to treatment discussions and assess patients health information-sourcing behaviour to better support patient involvement in decision-making.

Choosing Between Multinomial Logit and Multinomial Probit Models for Analysis of Unordered Choice Data
Creators: name: Kropko, Jonathan
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: Political researchers are often confronted with unordered categorical variables, such as the vote-choice of a particular voter in a multiparty election. In such situations, re-searchers must choose an appropriate empirical model to analyze this data. The two most commonly used models are the multinomial logit (MNL) model and the multinomial probit (MNP) model. MNL is simpler, but also makes the often erroneous independence of irrelevant alternatives (IIA) assumption. MNP is computationally intensive, but does not assume IIA, and for this reason many researchers have assumed that MNP is a better model. Little evidence exists, however, which shows that MNP will provide more accurate results than MNL. In this paper, I conduct computer simulations and show that MNL nearly always provides more accurate results than MNP, even when the IIA assumption is severely violated. The results suggest that researchers in the field should reconsider use of MNP as the most reliable empirical model.

description: We address the problem of model checking stochastic systems, i.e., checking whether a stochastic system satisfies a certain temporal property with a probability greater (or smaller) than a fixed threshold. In particular, we present a Statistical Model Checking (SMC) approach based on Bayesian statistics. We show that our approach is feasible for a certain class of hybrid systems with stochastic transitions, a generalization of Simulink/Stateflow models. Standard approaches to stochastic discrete systems require numerical solutions for large optimization problems and quickly become infeasible with larger state spaces. Generalizations of these techniques to hybrid systems with stochastic effects are even more challenging. The SMC approach was pioneered by Younes and Simmons in the discrete and non-Bayesian case. It solves the verification problem by combining randomized sampling of system traces (which is very efficient for Simulink/Stateflow) with hypothesis testing (i.e., testing against a probability threshold) or estimation (i.e., computing with high probability a value close to the true probability). We believe SMC is essential for scaling up to large Stateflow/Simulink models. While the answer to the verification problem is not guaranteed to be correct, we prove that Bayesian SMC can make the probability of giving a wrong answer arbitrarily small. The advantage is that answers can usually be obtained much faster than with standard, exhaustive model checking techniques. We apply our Bayesian SMC approach to a representative example of stochastic discrete-time hybrid system models in Stateflow/Simulink: a fuel control system featuring hybrid behavior and fault tolerance. We show that our technique enables faster verification than state-of-the-art statistical techniques. We emphasize that Bayesian SMC is by no means restricted to Stateflow/Simulink models. It is in principle applicable to a variety of stochastic models from other domains, e.g., systems biology.
POINT-OF-CARE HIV TESTING FOR EARLY INFANT DIAGNOSIS DURING THE POSTPARTUM PERIOD: TIMING AND TYPE OF TEST MATTERS

description: In the past decade, large gains have been made in reducing pediatric HIV infections during the prenatal or peripartum period. However, recent changes in the World Health Organization (WHO) breastfeeding guidelines will likely shift the majority of new infant HIV infections to the postnatal period1,2. Although breastfeeding guidelines have changed, early infant diagnosis (EID) recommendations have not been updated. In this dissertation, I evaluated the performance of two HIV rapid tests, Determine and Unigold, on a cohort of 121 Malawian HIV-exposed, breast-fed infants who were HIV negative at 6 weeks postpartum from 3 to 18 months of age. I also evaluated the cost-effectiveness for several EID strategies that varied in type, timing, and number of rapid tests, including an Alere test, a point-of-care virological assay, through Markov modeling. Among 121 HIV-exposed infants, the estimated specificity increased quicker for Unigold to 100% (95% CI: 95.4, 100.0) by age 12 months compared with 95.6% (90.7, 100.0) by 15 months of age for Determine. Both tests failed to detect several incident HIV infections. Seroreversion occurred sooner with Unigold with an earlier mean time to seroreversion by 62 days (95% CI: 60, 64). Among 21 different EID strategies, the lowest costing strategy was testing once with Unigold at 9 months ($18.20 per infant) and testing twice with Alere at 6 and 15 months ($145.60 per infant). The strategies with the lowest and highest effectiveness were testing once with Unigold at 9 months (337,806 disability-adjusted-life years [DALYs]) and testing twice at 6 and 15 months with Alere (192,588 DALYs). After sequentially comparing all strategies in ranked order by costs, six remained cost-effective. Our findings highlight that the type and timing of rapid test matters greatly in regard to accurately identifying and ruling out pediatric HIV infections. Updated guidelines for use of rapid tests in young HIV-exposed children that explicitly takes the type of test and infant age into account are urgently needed to ensure optimal care for the 1.5 million HIV-exposed infants born annually, especially in light of the new breastfeeding guidelines.

description: Direct collapse black holes (DCBH) have been proposed as a solution to the challenge of assembling supermassive black holes by $z>6$ to explain the bright quasars observed at this epoch. The formation of a DCBH seed with $\rm M_{BH}\sim10^{4-5}\ \rm M_{\odot}$ requires a pristine atomic-cooling halo to be illuminated by an external radiation field that is sufficiently strong to entirely suppress H$_{2}$ cooling in the halo. Many previous studies have attempted to constrain the critical specific intensity that is likely required to suppress H$_{2}$ cooling, denoted as $J_{\rm crit}$. However, these studies have typically assumed that the incident external radiation field can be modeled with a black-body spectrum. Under this assumption, it is possible to derive a {unique} value for $J_{\rm crit}$ that depends only on the temperature of the black-body. In this study we consider a more realistic spectral energy distribution (SED) for the external source of radiation that depends entirely on its star formation history and age. The rate of destruction of the species responsible for suppressing molecular hydrogen cooling depends on the detailed shape of the SED. Therefore the value of $J_{\rm crit}$ is tied to the shape of the incident SED of the neighbouring galaxy. We fit a parametric form to the rates of destruction of H$_2$ and H$^-$ that permit direct collapse. Owing to this, we find that $J_{\rm crit}$ is not a fixed threshold but can lie anywhere in the range $J_{\rm crit} \sim 0.5$--$10^{3}$, depending on the details of the source stellar population.

description: We propose the concept of fractal dimension of a set of points, in order to quantify the deviation from the uniformity distribution. Using measurements on real data sets (road intersections of U.S. counties, star coordinates from NASA's Infrared-Ultraviolet Explorer etc.) we provide evidence that real data indeed are skewed, and, moreover, we show that they behave as mathematical fractals, with a measurable, non-integer fractal dimension.Armed with this tool, we then show its practical use in predicting the performance of spatial access methods, and specifically of the R-trees. We provide the first  analysis of R-trees for skewed distributions of points: We develop a formula that estimates the number of disk accesses for range queries, given only the fractal dimension of the point set, and its count. Experiments on real data sets show that the formula is very accurate: the relative error is usually below 5%, and it rarely exceeds 10%.We believe that the fractal dimension will help replace the uniformity and independence assumptions, allowing more accurate analysis for any  spatial access method, as well as better estimates for query optimization on multi-attribute queries.

description: The purpose of this dissertation is to determine which combination of risk factors from Community Care of North Carolina's Pregnancy Medical Home risk screening form is most predictive of preterm birth and to compare receipt of postpartum contraception for women who experienced a recent preterm birth with women who had a term birth. This retrospective cohort includes pregnant Medicaid beneficiaries screened by the program who delivered a live birth in North Carolina between September 2011 and September 2012. Data come from Community Care of North Carolina's Case Management Information System, Medicaid claims, and birth certificates. The first paper of the dissertation designed and internally validated a predictive model of preterm birth using variables from the Pregnancy Medical Home risk screen. Logistic regression models and bootstrapping techniques indicated that the optimal combination of risk factors for PTB prediction include non-Hispanic black race, smoking during pregnancy, underweight, multi-fetal gestation, chronic disease (diabetes, hypertension, asthma, renal disease, and other chronic conditions), cervical insufficiency, nulliparity, and previous adverse reproductive outcomes (history of preterm birth, low birth weight baby, fetal death, and second trimester loss). Salient risk factors were identified for subgroups by parity and race/ethnicity including obesity, food insecurity, unsafe or unstable housing, and a short interpregnancy interval. Evaluation of the Pregnancy Medical Home risk screen provides insight to increase its sensitivity and specificity to improve identification of women early in pregnancy at highest risk for preterm birth. The second paper compared the prevalence of contraceptive receipt and effectiveness in Medicaid claims among women with and without a recent preterm birth using logistic and multinomial logistic regression. Contraceptive receipt was 50% (25% for the most effective methods) for women who delivered preterm at 90 days postpartum compared to 52% (28% for the most effective methods) among women who delivered full term. Women with a recent preterm birth with more than two children had lower odds of receiving contraception compared to equal parity women who delivered at term (OR = 0.84, 95% CI: 0.74, 0.96). Care management should focus on the provision of effective methods of contraception to women with a recent preterm birth.
Bit-Sliced Signature Files for Very Large Text Databases on a Parallel Machine Architecture

description: Free text retrieval is an important problem which can significantly
benefit from a parallel architecture. Signature methods have been
proposed to answer text retrieval queries in parallel machines [Sta88,
LF92], under the assumption that the main memory is sufficient to hold
the entire signature file. We propose the use of a Parallel Bit-Sliced Signature
File method on a SIMD machine architecture when the size of the
signature file exceeds the available memory. We propose that we need not
examine all the bit slices; instead we use a partial fetch slice swapping
algorithm. This method achieves graceful performance degradation according
to the database size. We provide formulae for the optimal number
of signature slices to fetch and match with the query signature. Arithmetic
examples show that our method can handle a 128GB database
with a 2sec response time on a machine with the characteristics of the
Connection Machine.

Boolean Analysis of MOS Circuits

description: The switch-level model represents a digital metal-oxide semiconductor (MOS) circuit as a network of charge storage nodes connected by resistive transistor switches. The functionality of such a network can be expressed as a series of systems of Boolean equations. Solving these equations symbolically yields a set of Boolean formulas that describe the mapping from input and current state to the new network states. This analysis supports the same class of networks as the switch-level simulator MOSSIM II and provides the same functionality, including the handling of bidirectional effects and indeterminate (X) logic values. In the worst case, the analysis of an n-node network can yield a set of formulas containing a total of O(n 3) operations. However, all but a limited set of dense, pass-transistor networks give formulas with O(n) total operations. The analysis can serve as the basis of efficient programs for a variety of logic design tasks, including logic simulation (on both conventional and special-purpose computers), fault simulation, test generation, and symbolic verification.

A Framework for Robust Assessment of Power Grid Stability and Resiliency

description: Security assessment of large-scale, strongly nonlinear power grids containing thousands to millions of interacting components is a computationally expensive task. Targeting at reducing the computational cost, this paper introduces a framework for constructing a robust assessment toolbox that can provide mathematically rigorous certificates for the grids' stability in the presence of variations in power injections, and for the grids' ability to withstand a bunch sources of faults. By this toolbox we can "off-line" screen a wide range of contingencies or power injection profiles, without reassessing the system stability on a regular basis. In particular, we formulate and solve two novel robust stability and resiliency assessment problems of power grids subject to the uncertainty in equilibrium points and uncertainty in fault-on dynamics. Furthermore, we bring in the quadratic Lyapunov functions approach to transient stability assessment, offering real-time construction of stability/resiliency certificates and real-time stability assessment. The effectiveness of the proposed techniques is numerically illustrated on a number of IEEE test cases.

description: The phrase model checking refers to algorithms for exploring the state space of a transition system to determine if it obeys a specification of its intended behavior. These algorithms can perform exhaustive verification in a highly automatic manner, and, thus, have attracted much interest in industry. Model checking programs are now being commercially marketed. However, model checking has been held back by the state explosion problem, which is the problem that the number of states in a system grows exponentially in the number of system components. Much research has been devoted to ameliorating this problem.

In this tutorial, we first give a brief overview of the history of model checking to date, and then focus on recent techniques that combine model checking with satisfiability solving. These techniques, known as bounded model checking, do a very fast exploration of the state space, and for some types of problems seem to offer large performance improvements over previous approaches. We review experiments with bounded model checking on both public domain and industrial designs, and propose a methodology for applying the technique in industry for invariance checking. We then summarize the pros and cons of this new technology and discuss future research efforts to extend its capabilities.
