Why Use Interactive Multi-Objective Optimization in Chemical Process Design?
2008
Problems in chemical engineering, like most real-world optimization problems, typically, have several conflicting performance criteria or objectives and they often are computationally demanding, which sets special requirements on the optimization methods used. In this chapter, we point out some shortcomings of some widely used basic methods of multi-objective optimization. As an alternative, we suggest using interactive approaches where the role of a decision maker or a designer is emphasized. Interactive multi-objective optimization has been shown to suit well for chemical process design problems because it takes the preferences of the decision maker into account in an iterative manner tha…
Testing and implementing a new approach to estimating interregional output multipliers using input-output data for South Korean regions
2020
Flegg's location quotient (FLQ) is a useful tool for estimating intraregional output multipliers. This paper uses it as one component when estimating interregional multipliers. Using statistical information criteria and official data for 16 South Korean regions, it is found that the best approach is to combine the FLQ with a simple trade model. The paper explains how the proposed procedure can be implemented for both multiple and individual regions, and also how a region-specific value for the unknown parameter δ in the FLQ formula can be determined. Finally, an illustrative case study of one of the regions is carried out.
The city management: methodological considerations on multriple criteria techniques for the selection and aggregation of criteria
2012
The scientific community recognizes that factors such as “social cohesion”, “social quality”, “social capital” and other have a strategic role in the evaluation of the en-richment or the impoverishment of society which occurs in urban environment. These factors are used to evaluate the quality of a social system and to discriminate between different policy alternatives in the management of the city. Social cohesion, quality, equity, progress, etc. are aggregate indicators of urban quality, as they incorporate various components related to multiple points of view. The scientific community and some national and international institutions have proposed different sets of indicators for the esti…
On the Stability of the Soft Pendulum With Affine Curvature: Open-Loop, Collocated Closed-Loop, and Switching Control
2022
This letter investigates the stability properties of the soft inverted pendulum with affine curvature - a template model for nonlinear control of underactuated soft robots. We look at how changes in physical parameters affect stability and equilibrium. We give conditions under which zero dynamics corresponding to a collocated choice of the output is (locally or globally) stable or unstable. We leverage these results to design a switching controller that stabilizes a class of nonlinear equilibria of the pendulum, which can drive the system from one equilibrium to another.
Criteria for the evaluation of requirements management tools supporting distributed software product line engineering and management
2015
The development of software product lines (SPL) by geographically distributed teams increases the complexity of requirements management (RM) related tasks, making the support of a RM tool necessary. However, the selection of the most appropriate RM tool can be challenging, therefore the use of a comprehensive criteria list guiding the selection becomes essential. The goal of this research is to determine whether available criteria lists include comprehensive criteria for the evaluation of RM tools to be adopted in distributed SPL requirements management. This research answers the following research questions: (1) Do currently available criteria lists for RM tool evaluation allow the assessm…
Diagnozowanie sprawności mówienia w perspektywie (nie tylko) egzaminu maturalnego
2015
The article discusses the difficulties of diagnosing speaking skills in the situation of matriculation examination, resulting from the specific nature of spoken language varieties and texts implementation in these variants. Factors that should be taken into account when formulating criteria for assessing speech and conversation exams are: complex and holistic structure of spoken speech, transience of audible text, the spontaneity of live speech, the power of nonverbal codes, a significant stigma of a dialog, and the influence of situational context on the course of communicative interaction. The analysis of speaking skills assessment tools prepared for the oral examination in the year 2015…
Using uncertain preferential information from stakeholders to assess the acceptability of alternative forest management plans
2017
In forest management planning, participatory planning processes are often encouraged as a means to acquire relevant information and to enhance the stakeholders' acceptability of alternative plans. This requires the aggregation of the stakeholders' preferences that can be done in a wide variety of manners. The aggregation process strives to reduce the information into a single set of preferences that simplifies the information and allows for the use of discrete decision support tools. Depending on how the preferences are aggregated, a wide range of plan rankings can emerge. Although this range of ranking complicates the issue of plan selection, it does highlight the uncertainty involved in a…
Stormwater Source Control as a Strategy for Sustainable Development: State of the Practice and Perceived Trends
2005
The primary objective of the paper is to draw upon the experiences acquired in many parts of the world to provide an up-to-date summary of the state of the practice for source control techniques and approaches, in a sustainable development context. After a discussion of the prevailing context for urban drainage approaches, three main themes covering techniques and design criteria, institutional aspects and performance issues are discussed relative to source control implementation. The discussion is based on findings from the compilation and analysis of available literature, recently developed databases, the experience of the different members of the SOCOMA group and recent research on desig…
Planeamiento territorial sostenible: un reto para el futuro de nuestras sociedades; criterios aplicados
2016
Resumen En buena parte de los 17 objetivos de desarrollo sostenible marcados como metas de la humanidad por la ONU se deja entrever la sostenibilidad. Debido al modelo socioproductivo dominante, el único modo de avanzar hacia territorios más sostenibles que permitan alcanzar y mantener el bienestar de la población mundial, es tener presente la necesidad de planificar adecuadamente el desarrollo territorial. Este trabajo reflexiona sobre esta necesidad y avanza en la definición de los principales criterios para alcanzar la sostenibilidad territorial en las escalas regionales y locales.
The value of synthetic linear epitope analogues of La/SSB for the detection of autoantibodies to La/SSB; specificity, sensitivity and comparison of m…
1998
SUMMARY In a previous study it was shown that La/SSB contains four linear epitopes, p147–154, p291–302, p301–318 and p349–364. The aim of the present study was to investigate the value of the synthetic epitope analogues of the La/SSB autoantigen for the detection of antibodies to La/SSB, in comparison with recombinant La and fragments of this protein. A total of 122 sera with anti-La/SSB activity, from patients with primary Sjögren's syndrome (pSS) or systemic lupus erythematosus (SLE), were tested in various peptide-based assays. In addition, 62 sera from pSS or SLE patients with other autoantibody specificities and 95 sera from healthy individuals were used as controls. The autoantibody s…
