Nurse Scheduling Problem: An Integer Programming Model with a Practical Application

2012

We use a binary integer programming model to formulate and solve a nurse scheduling problem (NSP) which maximally satisfies nurse preferences. In a practical application of a VA hospital, besides considering the scheduling of two types of nurses (registered nurses and licensed practical nurses), two other types of employees (nursing assistants and health care techs), one nurse manager, and a clinical nurse leader are also included in our model. Most of these employees are working full-time. In addition, we distinguish the schedule of weekdays and weekends with different requirements and different preferences for employees. Besides the requirements for each shift, we consider requirements fo…

Uz modeļu transformācijām balstītu rīku būves metožu izstrāde un realizācija

2012

Anotācija Promocijas darbā „Uz modeļu transformācijām balstītu rīku būves metožu izstrāde un realizācija” aplūkota uz modeļu transformācijām un metamodeļiem balstītu problēmorientētu rīku būves sfēra un risināta problēma, kā atvieglot šādu rīku izstrādi un lietošanu. Konkrēti aplūkota rīku būves platforma GRAF, kuras izstrādē autors piedalījies, un tā papildināta ar vairākiem servisiem, kas atvieglo rīku izstrādi ar šo platformu, kā arī ar to izstrādātu rīku uzturēšanu. Galvenie papildinājumi ietver vidēji augsta līmeņa modeļu transformāciju valodu izstrādi un realizāciju, metamodeļa skata jēdziena definēšanu un ieviešanu, kā arī modeļa un metamodeļa fragmenta specificēšanu, eksportu, impor…

Estrategia de enseñanza y aprendizaje de programación basada en la idea de ’hackathon’

2021

[EN] The acquisition of programming and data analysis skills in higher education is increa-singly necessary in all areas of Science and Engineering. In this paper we present a methodology for the motivation of programming learning, mainly focused on the deve-lopment of machine learning algorithms. This methodology is based on the hackathon idea and will have different levels. On the one hand the basic level where a competition is proposed in an improvised way during the development of the class. A second level where a programmed hackathon is proposed but within the classroom environment and using learning management systems such as Moodle. The last level consists of parti-cipation in an exte…

Multiple Objective Analysis of Input-Output Models for Emergency Management

1990

This paper shows how a visual, interactive, dynamic multiple objective linear programming decision support system can effectively be used for analyzing input-output models. We have applied our approach to studying the quantitative effects of economic or political crises to the Finnish economy. Examples of such crises are nuclear power plant accidents, trade embargoes, and international conflicts. An input-output model of the Finnish economy with 17 industries (sectors) is employed. Our system has been implemented on a microcomputer and is being used by the National Board of Economic Defense. Several typical case situations are discussed.

Stability Analysis and Stabilization of T-S Fuzzy Delta Operator Systems with Time-Varying Delay via an Input-Output Approach

2013

Published version of an article in the journal: Mathematical Problems in Engineering. Also available from the publisher at: http://dx.doi.org/10.1155/2013/913234 Open Access The stability analysis and stabilization of Takagi-Sugeno (T-S) fuzzy delta operator systems with time-varying delay are investigated via an input-output approach. A model transformation method is employed to approximate the time-varying delay. The original system is transformed into a feedback interconnection form which has a forward subsystem with constant delays and a feedback one with uncertainties. By applying the scaled small gain (SSG) theorem to deal with this new system, and based on a Lyapunov Krasovskii funct…

Understanding the shortcomings of commodity-based technology in input-output models: an economic-circuit approach

2004

International audience; The Make-Use Model serves as a basis for most national accounting systems as the System of National Accounts (SNA) and is acknowledged as the most suitable model for interregional analysis. Two hypotheses are traditionally made featuring either industry-based technologies (IBT) or commodity-based technologies (CBT). While industry-based technologies can be easily interpreted in terms of a demand-driven economic circuit, it will be shown that: (1) commodity-based technologies cannot be interpreted as a demand-driven economic circuit because this involves computing the inverse of a matrix (the matrix of industry output proportions), which is either impossible or genera…

Exploiting selective instruction reuse and value prediction in a superscalar architecture

2009

In our previously published research we discovered some very difficult to predict branches, called unbiased branches. Since the overall performance of modern processors is seriously affected by misprediction recovery, especially these difficult branches represent a source of important performance penalties. Our statistics show that about 28% of branches are dependent on critical Load instructions. Moreover, 5.61% of branches are unbiased and depend on critical Loads, too. In the same way, about 21% of branches depend on MUL/DIV instructions whereas 3.76% are unbiased and depend on MUL/DIV instructions. These dependences involve high-penalty mispredictions becoming serious performance obstac…

A Newcomer's Guide to EICS, the Engineering Interactive Computing Systems Community

2019

[EN] Welcome to EICS, the Engineering Interactive Computing Systems community, PACMHCI/EICS journal, and annual conference! In this short article, we introduce newcomers to the field and to our community with an overview of what EICS is and how it positions with respect to other venues in Human-Computer Interaction, such as CHI, UIST, and IUI, highlighting its legacy and paying homage to past scientific events from which EICS emerged. We also take this opportunity to enumerate and exemplify scientific contributions to the field of Engineering Interactive Computing Systems, which we hope to guide researchers and practitioners towards making their future PACMHCI/EICS submissions successful an…

GAIML: A New Language for Verbal and Graphical Interaction in Chatbots

2008

One of the aims of the research in the field of the human-computer interaction is the design of a natural and intuitive interaction modalities. In particular, many efforts have been devoted in the development of systems able to interact with the user in natural language. Chatbots are the classical interfaces for natural language interaction. Such systems can be very sophisticated, including support for 3D avatars and speech analysis and synthesis. However, all of them present only a text area allowing the user to input her sentences. No doubt, an interaction involving also the natural language can increase the comfort of the user with respect to common interfaces using only graphical widget…
