Bond-based 3D-chiral linear indices: Theory and QSAR applications to central chirality codification
2008
The recently introduced non-stochastic and stochastic bond-based linear indices are been generalized to codify chemical structure information for chiral drugs, making use of a trigonometric 3D-chirality correction factor. These improved modified descriptors are applied to several well-known data sets to validate each one of them. Particularly, Cramer's steroid data set has become a benchmark for the assessment of novel quantitative structure activity relationship methods. This data set has been used by several researchers using 3D-QSAR approaches such as Comparative Molecular Field Analysis, Molecular Quantum Similarity Measures, Comparative Molecular Moment Analysis, E-state, Mapping Prope…
Stochastic Control Problems
2003
The general theory of stochastic processes originated in the fundamental works of A. N. Kolmogorov and A. Ya. Khincin at the beginning of the 1930s. Kolmogorov, 1938 gave a systematic and rigorous construction of the theory of stochastic processes without aftereffects or, as it is customary to say nowadays, Markov processes. In a number of works, Khincin created the principles of the theory of so-called stationary processes.

Bridging Strategic Project Planning with Tactical Planning in the Design Process
2020
The paper studies the issue of bridging strategic planning with tactical/operative planning in the design process of complex AEC-projects. The paper present user-friendly planning methods on a tactical level which gives the planner intuitive control over dependent, independent, and interdependent tasks during the design process. In our understanding the planning process starts at the strategic level using integrated milestones as a prerequisite for handling progress and strategic coordination in projects. Moving forward in the planning process towards the operative level, the process requires flexible and agile methods which ensures robustness in the various plans that must be made. In this…
The Strategic Scorecards: An Instrumentation of the Strategic Management Accounting. Exploration of a Concept, Instrumentation and Results from a Fre…
2003
I describe in this study a generic model of strategic management accounting instrumentation: the strategic scorecards. In order to build this generic model, I review in the existing literature the concepts of Strategic Control and Strategic Management Accounting (SMA). I present the characteristics of these concepts and analyse the reasons why they emerged. I show how the strategic scorecards are an instrumentation of the SMA in studying the most widely known and esteemed scorecards: the Balanced Scorecards (Kaplan & Norton, 1996) and Skandia's Navigator (Edvinsson & Malone, 1997). I then clarify the outlines for a generic model of strategic scorecard and disclose an "a priori" typology of …
An Approximate Technique for Dynamic Elastic-Plastic Analysis
1994
The possibility of obtaining an approximate sufficiently reliable response for elasticplastic discretized structures subjected to dynamic load (kinematical and/or mechanical), with alow computational effort, has been considered. A suitable technique to this effect comes from the form of the dynamic influence matrix of imposed plastic strains on self-stresses, which is shaped by adding up a sparse time-dependent matrix and a block diagonal time-independent matrix (which is the sum of two block diagonal matrices). Several cases of practical interest have been studied, among these cases a special one where all the degrees-of-freedom are dynamic. The technique is compared to other approximate t…
Structuring Humanitarian Supply Chain Knowledge Through a Meta-Modeling Approach
2017
To develop decision support systems (DSS) that improve humanitarian supply chain (HSC) performance, there is a need for methods that support on field data gathering and knowledge structure. We propose a meta-model to structure the knowledge of HSC and to obtain a shared vision of the HSC. It has been developed to provide a framework to class gathered data by connecting it to HSC concepts. The meta-model includes four packages, defining the collaborative ecosystem (context, actors, objectives, and behavior). The concepts gathered during our field research experiences, added to the HSC core literature, have permitted to build the HSC meta-model layer. Models built from this meta-model can be …
Memetic algorithms and memetic computing optimization: A literature review
2012
Abstract Memetic computing is a subject in computer science which considers complex structures such as the combination of simple agents and memes, whose evolutionary interactions lead to intelligent complexes capable of problem-solving. The founding cornerstone of this subject has been the concept of memetic algorithms, that is a class of optimization algorithms whose structure is characterized by an evolutionary framework and a list of local search components. This article presents a broad literature review on this subject focused on optimization problems. Several classes of optimization problems, such as discrete, continuous, constrained, multi-objective and characterized by uncertainties…
On Interacting with Collective Knowledge of Group Facilitation
2013
Group decision process design is a well-known class of ill-structured, dynamic, and going-concerns problem. The paper presents a human-computer interaction engineering approach to design a software prototype that provides personalized, contextual and actionable recommendations for this problem. The approach emphasizes the computational aspects of collective intelligence to structure these recommendations based on the collective knowledge that reflects not only the design space per se, but the collective experience in exploiting it as well. It is demonstrated by: 1) detailing the engineering issues of an implemented prototype for the group decision process design; and 2) explaining its funct…
