The Early Stage (ES) intermediate represents the starting structure in protein folding simulations based on the Fuzzy Oil Drop (FOD) model. The accuracy of FOD predictions is greatly dependent on the accuracy of the chosen intermediate. A suitable intermediate can be constructed using the sequence-structure relationship information contained in the so-called contingency table - this table expre...

We present a comprehensive study of graphical log-linear models for contingency tables. High dimensional contingency tables arise in many areas such as computational biology, collection of survey and census data and others. Analysis of contingency tables involving several factors or categorical variables is very hard. To determine interactions among various factors, graphical and decomposable l...

Contingency tables represent data in a granular way and are a well-established tool for inductive generalization of knowledge from data. We show that the basic concepts of rough sets, such as concept approximation, indiscernibility, and reduct can be expressed in the language of contingency tables. We further demonstrate the relevance to rough sets theory of additional probabilistic information...

Electronic Health Record system downtimes may have a great impact on patient care continuity. This paper describes the analysis and actions taken to redesign the Contingency Plan Procedure for the Electronic Health Record System of Hospital Italiano de Buenos Aires. After conducting a thorough analysis of the data gathered at post-contingency meetings, weaknesses were identified in the procedur...

The Design-to-Criteria scheduler is a domain independent system that schedules complex AI problem solving tasks to meet real-time performance goals. In this paper, we further extend the scheduler to more eeectively deal with uncertainty present in a schedule which can be critical in hard deadline or hard cost situations. This is based on an analysis of available schedules that can be used to re...

Santa Muerte is one of the fastest growing folk saint movements in Mexico. She has a core following in Mexico among dispossessed populations, but also devotees from a broader swath of the Mexican population. This article analyzes the development of Santa Muerte veneration in Mexico since 2000. I argue that, from a structural analysis perspective, Santa Muerte veneration is on the threshold of d...

This paper presents a new approach to analysing and understanding civil emergency planning based on the notion of responsibility modelling combined with HAZOPS analysis of information requirements. Our goal is to represent complex contingency plans so that they can be more readily understood, so that inconsistencies can be highlighted and vulnerabilities discovered. In this paper, we outline th...

Triangular contingency tables are a special class of incomplete contingency tables. Association and independence models are used to analyze such tables. Association models can be described in terms of the association parameters for the analysis of triangular contingency tables having ordered categories. The aim of this study is to show the relation between the association parameters of the unif...

The importance of preventing the voltage collapse is gaining importance due to increase in dependency on the use of electricity. This has compelled the utilities to maintain high system reliability. The evaluation of a power systems ability to withstand dangerous contingencies and to survive to a normal or acceptable operating point is a prerequisite for security analysis. Line outage often cau...

The contingency assessment situation and the signal detection situation are similar in that the information on which the decision is based is uncertain. Nevertheless the two research endeavours have progressed independently, each with its own traditions and each motivated by different theoretical perspectives. Recently, some researchers have integrated these two lines of research and have demon...
