description: We study theoretically the Josephson effect in junctions based on unconventional superconductors with diffusive barriers, using the quasiclassical Green's function formalism. Generalized boundary conditions at junction interfaces applicable to unconventional superconductors are derived by calculating a matrix current within the circuit transport theory. Applying these boundary conditions, we have calculated the Josephson current in structures with various pairing symmetries. A number of predictions are made: (a) nonmonotonic temperature dependence in d-wave superconductor/diffusive normal metal/d-wave superconductor (D/DN/D) junctions, (b) anomalous current-phase relation in $p $-wave superconductor/diffusive normal metal/$p$% -wave superconductor (P/DN/P) junctions, (c) second harmonics in D/DN/D and P/DN/P junctions, (d) a double peak structure of the critical current in D/DF/D junctions, (e) enhanced Josephson current by the exchange field in S/DF/P junctions. We have also investigated peculiarities of the Josephson coupling in D/DF/D, P/DF/P and S/DF/P junctions. An oscillatory behavior of the supercurrent and the second harmonics in the current-phase relation are studied as a function of the length of the diffusive ferromagnet.

description: By estimating 3D shape and instances from a single view, we can capture information about an environment quickly, without the need for comprehensive scanning and multi-view fusion. Solving this task for composite scenes (such as object stacks) is challenging: occluded areas are not only ambiguous in shape but also in instance segmentation; multiple decompositions could be valid. We observe that physics constrains decomposition as well as shape in occluded regions and hypothesise that a latent space learned from scenes built under physics simulation can serve as a prior to better predict shape and instances in occluded regions. To this end we propose SIMstack, a depth-conditioned Variational Auto-Encoder (VAE), trained on a dataset of objects stacked under physics simulation. We formulate instance segmentation as a centre voting task which allows for class-agnostic detection and doesn't require setting the maximum number of objects in the scene. At test time, our model can generate 3D shape and instance segmentation from a single depth view, probabilistically sampling proposals for the occluded region from the learned latent space. Our method has practical applications in providing robots some of the ability humans have to make rapid intuitive inferences of partially observed scenes. We demonstrate an application for precise (non-disruptive) object grasping of unknown objects from a single depth view.

description: We calculate the branching ratio of $\bar{B}^0 \to Λ_c^+ \bar{p}$ in the PQCD approach. Most previous model calculations obtained branching ratios significantly larger than experimental data. We find that the predicted branching ratio for BR$(\bar{B}^0 \to Λ_c^+ \bar{p})$ in the PQCD approach can vary over a range of $(2.3\sim 5.1)\times 10^{-5}$ with the largest uncertainty coming from the parameters in the wave function of $Λ_c$. With the favored values for the parameters in the $Λ_c^+$ wave function, $β= 1$ GeV and $m_q = 0.3$ GeV, the branching ratio is about $2.3\times 10^{-5}$ which is satisfactorily consistent with the value measured by experiments.

description: Correlations between the arrival time and the energy of photons emitted in outbursts of astrophysical objects are predicted in quantum and classical gravity scenarios and can appear as well as a result of complex acceleration mechanisms responsible for the photon emission at the source. This paper presents a robust method to study such correlations that overcomes some limitations encountered in previous analysis, and is based on a Likelihood function built from the physical picture assumed for the emission, propagation and detection of the photons. The results of the application of this method to a flare of Markarian 501 observed by the MAGIC telescope are presented. The method is also applied to a simulated dataset based on the flare of PKS 2155-304 recorded by the H.E.S.S. observatory to proof its applicability to complex photon arrival time distributions.

description: Nonmagnetic disorder is shown to quench the screening of magnetic moments in metals, the Kondo effect. The probability that a magnetic moment remains free down to zero temperature is found to increase with disorder strength. Experimental consequences for disordered metals are studied. In particular, it is shown that the presence of magnetic impurities with a small Kondo temperature enhances the electron's dephasing rate at low temperatures in comparison to the clean metal case. It is furthermore proven that the width of the distribution of Kondo temperatures remains finite in the thermodynamic (infinite volume) limit due to wave function correlations within an energy interval of order $1/τ$, where $τ$ is the elastic scattering time. When time-reversal symmetry is broken either by applying a magnetic field or by increasing the concentration of magnetic impurities, the distribution of Kondo temperatures becomes narrower.

Studies toward a total synthesis of (±)-subergorgic acid

Publisher: name: University of British Columbia

description: This thesis describes synthetic studies directed towards the total synthesis of (±)-subergorgic acid (8) and the development of methodology for the conversion of cyclopentanones into cyclopentenones. In the synthetic studies directed towards the total synthesis of (±)-subergorgic acid (8), the known keto ketal 101 was converted into the enone 100. Copper(I)-catalyzed conjugate addition of the Grignard reagent 91 to the enone 100, followed by intramolecular alkylation of the intermediate enolate anion, provided the triquinane 99. Sequential deoxygenation of the keto function in 99 and oxidative cleavage of the double bond provided the ketone 103. The ketone 103 was converted into dienedione 98 via a four step sequence, involving Saegusa oxidation to give 156, deketalization of the ketal function and benzeneseleninic acid anhydride (BSA) mediated dehydrogenation of the intermediate 157. The dienedione 98 was alkylated to provide 107. Conversion of the enone 157 into the dienedione 98 required the development of new methodology for the conversion of cyclopentanones into the corresponding cyclopentenones. Reactions of di- and triqiunanes [sic] such as 133 and 157 with BSA provided the corresponding enones 250 and 98, respectively.

description: Stochastic interdependence of a probablility distribution on a product space is measured by its Kullback-Leibler distance from the exponential family of product distributions (called multi-information). Here we investigate low-dimensional exponential families that contain the maximizers of stochastic interdependence in their closure. Based on a detailed description of the structure of probablility distributions with globally maximal multi-information we obtain our main result: The exponential family of pure pair-interactions contains all global maximizers of the multi-information in its closure.

description: Diffusion of interstitial alloying elements like H, O, C, and N in metals and their continuous relocation and interactions with their microstructures have crucial influences on metals properties. However, besides limitations in experimental tools in capturing these mechanisms, the inefficiency of numerical tools also inhibits modeling efforts. Here, we present an efficient framework to perform hybrid grand canonical Monte Carlo and molecular dynamics simulations that allow for parallel insertion/deletion of Monte Carlo moves. A new methodology for calculation of the energy difference at trial moves that can be applied to many-body potentials as well as pair ones is a primary feature of our implementation. We study H diffusion in Fe (ferrite phase) and Ni polycrystalline samples to demonstrate the efficiency and scalability of the algorithm and its application. The computational cost of using our framework for half a million atoms is a factor of 250 less than the cost of using existing libraries.

In the simple linear regression model, the first-order asymptotic distribution of the least square estimator of the slope parameter is observed to be degenerate. However, in the second order, this estimator is $n^{1/2}$-consistent and asymptotically normal for $h+H<3/2$; nonnormal otherwise, where $h$ and $H$ are LM parameters of design and error processes, respectively. The finite-dimensional asymptotic distributions of a class of kernel type estimators of the conditional variance function $σ^2(x)$ in a more general heteroscedastic regression model are found to be normal whenever $H

description: Abstract

This paper aims to review the factors influencing the performance of PMS in increasing the performance of higher education institutions in the Delhi/NCR region. That is the reason why the following research questions have been developed for the study: The research intends to determine how demographic factors like age, gender, and total working experience influence this relationship. “Thus, it can be imperative that PMS convey efficiency to boost up the quantity and qualitatively of productive faculty and overall institutional performance. In line with the above study questions, this research synthesizes current research and collects empirical information from different higher education institutions in order to determine the components of a PMS and the impact that it has on Faculty Performance. The research instrument adopted for data collection was a structured questionnaire administered on faculty members in various higher learning institutions in Delhi/NCR. The study also shows that there is a direct relation between the structural organization of PMS and increased performance by the faculty and this was observed across all categories of the faculty. The findings of the study revealed that both age and total work experience significantly moderated the relationship between the sources of information and organisational variables, however gender had less but a significant effect. This analysis shows that the junior and relatively less experienced faculty staffs seemed to stand to gain from formal and rigorous performance management practices than their seniors in terms of age and years of service. Consequently, the study offers a roadmap on how directors of Higher Learning Institutions can enhance PMS to meet the organizational needs of their disparate faculty, thus, proactively formulas and implements fairness, effectiveness, and conformity to organizational demographic factions. This work can be of significant value in continuing the debate and dialogue on how to get the best from faculty through effective HRM approaches and offers a platform for other researches in similar settings.

description: Several recent studies have indicated that artificial subhalo disruption (the spontaneous, non-physical disintegration of a subhalo) remains prevalent in state-of-the-art dark matter-only cosmological simulations. In order to quantify the impact of disruption on the inferred subhalo demographics, we augment the semi-analytical SatGen dynamical subhalo evolution model with an improved treatment of tidal stripping that is calibrated using the DASH database of idealized high-resolution simulations of subhalo evolution, which are free from artificial disruption. We also develop a model of artificial disruption that reproduces the statistical properties of disruption in the Bolshoi simulation. Using this framework, we predict subhalo mass functions (SHMFs), number density profiles, and substructure mass fractions and study how these quantities are impacted by artificial disruption and mass resolution limits. We find that artificial disruption affects these quantities at the $10-20\%$ level, ameliorating previous concerns that it may suppress the SHMF by as much as a factor of two. We demonstrate that semi-analytical substructure modeling must include orbit integration in order to properly account for splashback haloes, which make up roughly half of the subhalo population. We show that the resolution limit of $N$-body simulations, rather than artificial disruption, is the primary cause of the radial bias in subhalo number density found in dark matter-only simulations. Hence, we conclude that the mass resolution remains the primary limitation of using such simulations to study subhaloes. Our model provides a fast, flexible, and accurate alternative to studying substructure statistics in the absence of both numerical resolution limits and artificial disruption.

description: The ALMA North American and European prototype antennas have been evaluated by a variety of measurement systems to quantify the major performance specifications. Nearfield holography was used to set the reflector surfaces to 17 microns RMS. Pointing and fast switching performance was determined with an optical telescope and by millimeter wavelength radiometry, yielding 2 arcsec absolute and 0.6 arcsec offset pointing accuracies. Path length stability was measured to be less than or approximately equal to 20 microns over 10 minute time periods using optical measurement devices. Dynamical performance was studied with a set of accelerometers, providing data on wind induced tracking errors and structural deformation. Considering all measurements made during this evaluation, both prototype antennas meet the major ALMA antenna performance specifications.

Η κοινωνική μητέρα, αναλαμβάνει να μεγαλώσει, να αναθρέψει και να ανταποκριθεί σε όλες τις ανάγκες του παιδιού. Τόσο το ίδιο το παιδί που πρόκειται να γεννηθεί, όσο και η παρένθετη μητέρα εισάγονται σε ένα πλαίσιο, όπου κυριαρχούν οι όροι της αγοράς.

description: The purpose of this thesis was to present the ethical problems arising from the methods of Medically Assisted Reproduction and in particular the practice of surrogate motherhood. In this practice, the woman who conceives and gives birth is not the same as the woman who has the egg used for fertilization. It is the case that the social mother addresses an "egg donor" because she has issues with both her reproductive material and pregnancy. The "donor" of the egg, through the IVF, sells her eggs to the infertile woman, who then finds a surrogate, in order to conceive the IVF. The social mother undertakes to grow, nurture and respond to all the needs of the child. Both the child to be born and the surrogate mother are brought into a context where market conditions are dominant. Finally, all the ethical problems arising from the method of surrogate motherhood are revealed in detail in the thesis, a method that certainly undermines human dignity

description: Motivated by the recent LHCb announcement of a $3.1σ$ violation of lepton-flavor universality in the ratio $R_K=Γ(B\to Kμ^+μ^-)/Γ(B\to K e^+ e^-)$, we present an updated, comprehensive analysis of the flavor anomalies seen in both neutral-current ($b\to s\ell^+\ell^-$) and charged-current ($b\to cτ\barν$) decays of $B$ mesons. Our study starts from a model-independent effective field-theory approach and then considers both a simplified model and a UV-complete extension of the Standard Model featuring a vector leptoquark $U_1$ as the main mediator of the anomalies. We show that the new LHCb data corroborate the emerging pattern of a new, predominantly left-handed, semileptonic current-current interaction with a flavor structure respecting a (minimally) broken $U(2)^5$ flavor symmetry. New aspects of our analysis include a combined analysis of the semileptonic operators involving tau leptons, including in particular the important constraint from $B_s$--$\bar B_s$ mixing, a systematic study of the effects of right-handed leptoquark couplings and of deviations from minimal flavor-symmetry breaking, a detailed analysis of various rare $B$-decay modes which would provide smoking-gun signatures of this non-standard framework (LFV decays, di-tau modes, and $B\to K^{(*)}ν\barν$), and finally an updated analysis of collider bounds on the leptoquark mass and couplings.

description: We consider the classical three-dimensional motion in a potential which is the sum of $n$ attracting or repelling Coulombic potentials. Assuming a non-collinear configuration of the $n$ centres, we find a universal behaviour for all energies $E$ above a positive threshold. Whereas for $n=1$ there are no bounded orbits, and for $n=2$ there is just one closed orbit, for $n\geq 3$ the bounded orbits form a Cantor set. We analyze the symbolic dynamics and estimate Hausdorff dimension and topological entropy of this hyperbolic set. Then we set up scattering theory, including symbolic dynamics of the scattering orbits and differential cross section estimates. The theory includes the $n$--centre problem of celestial mechanics, and prepares for a geometric understanding of a class of restricted $n$-{\em body} problems. To allow for applications in semiclassical molecular scattering, we include an additional smooth (electronic) potential which is arbitrary except its Coulombic decay at infinity. Up to a (optimal) relative error of order 1/E, all estimates are independent of that potential but only depend on the relative positions and strengths of the centres. Finally we show that different, non-universal, phenomena occur for collinear configurations.

description: For many random Constraint Satisfaction Problems, by now, we have asymptotically tight estimates of the largest constraint density for which they have solutions. At the same time, all known polynomial-time algorithms for many of these problems already completely fail to find solutions at much smaller densities. For example, it is well-known that it is easy to color a random graph using twice as many colors as its chromatic number. Indeed, some of the simplest possible coloring algorithms already achieve this goal. Given the simplicity of those algorithms, one would expect there is a lot of room for improvement. Yet, to date, no algorithm is known that uses $(2-ε) χ$ colors, in spite of efforts by numerous researchers over the years. In view of the remarkable resilience of this factor of 2 against every algorithm hurled at it, we believe it is natural to inquire into its origin. We do so by analyzing the evolution of the set of $k$-colorings of a random graph, viewed as a subset of $\{1,...,k\}^{n}$, as edges are added. We prove that the factor of 2 corresponds in a precise mathematical sense to a phase transition in the geometry of this set. Roughly, the set of $k$-colorings looks like a giant ball for $k \ge 2 χ$, but like an error-correcting code for $k \le (2-ε) χ$. We prove that a completely analogous phase transition also occurs both in random $k$-SAT and in random hypergraph 2-coloring. And that for each problem, its location corresponds precisely with the point were all known polynomial-time algorithms fail. To prove our results we develop a general technique that allows us to prove rigorously much of the celebrated 1-step Replica-Symmetry-Breaking hypothesis of statistical physics for random CSPs.

description: We are interested in the structure of the Lcc vertex in the Yang-Mills theory, where c is the ghost field and L the corresponding BRST auxiliary field. This vertex can give us information on other vertices, and the possible conformal structure of the theory should be reflected in the structure of this vertex. There are five two-loop contributions to the Lcc vertex in the Yang-Mills theory. We present here calculation of the first of the five contributions. The calculation has been performed in the position space. One main feature of the result is that it does not depend on any scale, ultraviolet or infrared. The result is expressed in terms of logarithms and Davydychev integral J(1,1,1) that are functions of the ratios of the intervals between points of effective fields in the position space. To perform the calculation we apply Gegenbauer polynomial technique and uniqueness method.

description: Terahertz (THz) wireless communication is envisioned as a promising technology, which is capable of providing ultra-high-rate transmission up to Terabit per second. However, some hardware imperfections, which are generally neglected in the existing literature concerning lower data rates and traditional operating frequencies, cannot be overlooked in the THz systems. Hardware imperfections usually consist of phase noise, in-phase/quadrature imbalance, and nonlinearity of power amplifier. Due to the time-variant characteristic of phase noise, frequent pilot insertion is required, leading to decreased spectral efficiency. In this paper, to address this issue, a novel pilot design strategy is proposed based on index modulation (IM), where the positions of pilots are flexibly changed in the data frame, and additional information bits can be conveyed by indices of pilots. Furthermore, a turbo receiving algorithm is developed, which jointly performs the detection of pilot indices and channel estimation in an iterative manner. It is shown that the proposed turbo receiver works well even under the situation where the prior knowledge of channel state information is outdated. Analytical and simulation results validate that the proposed schemes achieve significant enhancement of bit-error rate performance and channel estimation accuracy, whilst attaining higher spectral efficiency in comparison with its classical counterpart.

description: Το θέμα της διπλωματικής εργασίας είναι η οικιστική ανάπτυξη σε δάση και δασικές εκτάσεις. Το κυρίως μέρος της εργασίας αποτελείται από τρία κεφάλαια: στο πρώτο εξ αυτών δίδεται ο ορισμός του δάσους και της δασικής έκτασης, όπως έχει προκύψει μέσα από μία πληθώρα νομοθετικών μεταβολών και αντίστοιχης νομολογιακής επεξεργασίας, ενώ παράλληλα γίνεται αναφορά και σε άλλες συναφείς εκτάσεις, στις οποίες επεκτείνεται το προστατευτικό πεδίο των διατάξεων που αφορούν τα δάση. Επίσης, εξετάζεται το κανονιστικό πλαίσιο που διέπει τη διαδικασία κατάρτισης δασικών χαρτών και σύνταξης δασολογίου, αλλά και την προσωρινή διαδικασία χαρακτηρισμού μίας έκτασης ως δασικής, τόσο στο διοικητικό όσο και στο δικαστικό στάδιο. Το δεύτερο κεφάλαιο πραγματεύεται το δικαίωμα στη δόμηση. Πιο συγκεκριμένα, αναπτύσσεται η θεμελίωση του δικαιώματος σε κανόνες υπερνομοθετικής ισχύος, η νομική του φύση και το κανονιστικό του περιεχόμενο. Τέλος, το τρίτο κεφάλαιο αποτελεί έναν συγκερασμό των δύο προηγούμενων, καθώς εξετάζει την επιρροή που ασκείται στο δικαίωμα στη δόμηση και τους περιορισμούς που τίθενται ενόψει των διατάξεων που θεσπίζουν την προστασία του περιβάλλοντος και ειδικότερα των δασών και των δασικών εκτάσεων
description: The subject of the thesis is the residential development in forests and wooded areas. The main part consists of three chapters: in the first the definition of the forest and the wooded area is presented, as it emerged through a plethora of legislative changes and corresponding case law processing, while also mentioning other relevant areas, where the protective field of the ordinances that concern the forests is expanded. Also, the regulatory framework that rules the procedure of the forest maps is examined, as well as the temporary procedure of characterization of an area as forest in the administrative and judicial stage. The second chapter deals with the right to build. More specifically, the foundation of the right in the constitution and the European convention on human rights, its legal nature and its regulatory content are analyzed. Finally, the third chapter is a combination of the previous chapters, as it examines the influence that is exercised on the right to build and the restrictions that are set in view of the ordinances that establish the protection of the environment and in particular the forests and the wooded areas

description: This thesis is co-authored as part of the Master's Degree Program in Systematic Philosophy of the Aristotle University of Thessaloniki and deals with the problem of doping in sport. Initially, the introduction to the subject is listed, and then the chapters of the work begin to list, with the first one relating to how sport and Olympic ideals were in antiquity. The second chapter gives the definition of doping, while the third begins with a historical overview of the phenomenon. The fourth chapter then describes the dimensions that the problem has taken in modern times. Then, both the arguments of the proponents of doping and its critics are presented. In the seventh chapter of the work, we report on the health problems caused by doping as well as the various effects of anabolic substances. The eighth chapter goes on to highlight the ethical problems that the phenomenon raises, while the ninth and last chapters set out the legal framework at both European and Greek level regarding doping. Finally, the work concludes with the conclusions of the author's position on the subject

description: We have constructed a Lagrangian model (SIG-OM) with coupling of sigma and omega mesons in the relativistic mean-field theory. Properties of finite nuclei and nuclear matter have been explored with the new Lagrangian model. The study shows that with SIG-OM an excellent description of binding energies and charge radii of nuclei over a large range of isospin is achieved. With an incompressibility of nuclear matter K=265 MeV, it is also able to describe the breathing-mode isoscalar giant monopole resonance energies appropriately. It is shown that the high-density behaviour of the equation of state of nuclear and neutron matter with the sigma-omega coupling is significantly softer than the non-linear scalar coupling model.

On the relationship between entropy and information

description: In this paper, we analyze the relationship between entropy and information in the context of the mixing process of two identical ideal gases. We will argue that entropy has a special information-based feature that is enfolded in the statistical entropy, but the second law does not include it directly. Therefore, in some given processes in thermodynamics where there is no matter and energy interaction between the system and environment, the state of the system may go towards a situation of lower probability to increase observer's information in environment. This is a kind of an information-based interaction in which the total entropy is not constrained by the second law.

The synthesis and characterization of new sulfoxide complexes of ruthenium and their potential as anti-cancer agents
Creators: name: Yapp, Donald Tshin Tsun

description: Areas of hypoxia (low O₂ content) within malignant tumours are often resistant to radiotherapy and chemotherapy. Compounds that work in conjunction with radiation or alone are required to remove or define hypoxic areas. The complexes cis-RuCl₂(DMS̲O)₃(DMSO̲) (1) and cis-RuCl₂(TMS̲O)₄ (3) (the figure [in actual abstract] shows the sulfoxide structures) were previously used as precursors for the synthesis of Ru(II)-sulfoxide-nitroimidazole complexes. The structural chemistry and spectroscopic data of Ru/DMSO/TMSO complexes are reviewed. RuCl₂(TMS̲O)₄, previously assigned a Trans geometry, is shown to be cis; two crystal forms are characterized crystallographically. Two bromo-Ru(II) complexes of TMSO, [RuBr₃(TMSO)₄Li]₂ and trans-RuBr₂(TMS̲O)₄, are isolated, and both compounds are subsequently characterized by X-ray crystallography. The dimer contains four kinds of coordinated TMSO ligands: the formulation is best written as [Br₆(TMS̲O)₂Ru₂(μ₂-TMS̲O̲)(μ₃- TMS̲O̲)₂Li₂(TMSO̲̲)₂], and reveals a unique μ₃-type sulfoxide ligand. The dinuclear, mixed valence Ru-sulfoxide complexes Ru₂Cl₅(Et₂SO)₄, Ru₂Cl₅(ⁿPr₂SO)₅ and Ru₂Cl₅(ⁿBu₂SO)₅, and monomeric Ru(III) complexes of ⁿPr₂SO and Ph₂SO are synthesized and characterized spectroscopically. The two Ru(III) complexes are structurally characterized as [H(ⁿPr₂SO̲)₂][trans-RuCl₄(ⁿPr₂SO̲)₂] and mer-RuCl₃(Ph₂SO̲)(Ph₂SO̲)(MeOH). The former complex reveals the presence of a cation containing the strongly hydrogen-bonded ⁿPr₂SO‧‧H‧‧OSⁿPr moiety; the latter complex reveals a coordinated methanol ligand (H-bonded to the O atom of Ph₂S̲O), as well as both sulfur- and oxygen-bonded Ph₂SO ligands. Four ruthenium (II) complexes of chelating sulfoxides are also synthesized and structurally characterized. The data for the complexes trans-RuCl₂(BMSE)₂ (4), cis-RuCl₂(BESE)₂ (5), trans-RuCl₂(BPSE)₂ (6) and cis-RuCl₂(BMSP)₂ (7) reveal in each case only S-bonded sulfoxides. The unit cell of complex 4, in addition, contains a water molecule strongly hydrogen-bonded to two chloride atoms from two different molecules of the complex. Seven of the characterized Ru-sulfoxide complexes (1 - 7) are tested in vitro using Chinese hamster ovary (CHO) cells. The biological data indicate that the complexes accumulate in CHO cells, without hypoxic selectivity. No toxicity is observed at the complex concentrations used (1.0 mM for 1 - 4, 7; 0.50 mM for 5 and 6) despite evidence that all seven complexes bind to DNA. Of some interest, the trans- complexes (2, 4, 6) accumulate in CHO cells and bind to DNA to a greater degree than the cis complexes.

description: This paper presents an approach to the study of cognitive activities in collaborative software development. This approach has been developed by a multidisciplinary team made up of software engineers and cognitive psychologists. The basis of this approach is to improve our understanding of software development by observing professionals at work. The goal is to derive lines of conduct or good practices based on observations and analyses of the processes that are naturally used by software engineers. The strategy involved is derived from a standard approach in cognitive science. It is based on the videotaping of the activities of software engineers, transcription of the videos, coding of the transcription, defining categories from the coded episodes and defining cognitive behaviors or dialogs from the categories. This project presents two original contributions that make this approach generic in software engineering. The first contribution is the introduction of a formal hierarchical coding scheme, which will enable comparison of various types of observations. The second is the merging of psychological and statistical analysis approaches to build a cognitive model. The details of this new approach are illustrated with the initial data obtained from the analysis of technical review meetings.
