Extending a Metamodel for Formalization of Data Warehouse Requirements

2014

In performance measurement systems that are built on top of a data warehouse, the information requirements in natural language are different performance indicators that should be stored and analyzed. We use the requirement formalization metamodel to create a formal requirement repository out of information requirements in natural language. In the course of this research we tested the compatibility of the existing requirement formalization metamodel applying it to a set of over 150 requirements for the currently operating data warehouse project. As a result, we extended the formal specification of information requirements with some additional classes like themes, grouping, and requirement pr…

Energy saving in wastewater treatment plants: A plant-generic cooperative decision support system

2017

Abstract In Europe, the analysis of Waste Water Treatment Plants (WWTPs) shows a significant energy efficiency potential (up to 25%). Optimistically, plant managers assess their plant efficiency once or twice per year. Consequently, the time gap between an inefficiency and its detection produces avoidable operational costs. Although the installation of multiple on-line sensors can provide detailed energy information, for a human operator it is unrealistic to analyse the produced data in a satisfactory time-scale. This paper proposes a cooperative tool for energy saving that remotely accesses and evaluates WWTP databases to produce daily energy assessment reports. The novelty of this decisio…

Monitoring Results and Energy Performances Evaluation of Freescoo Solar DEC Systems

2016

Abstract This work addresses the energy saving performances of some solar Desiccant and Evaporative Cooling (DEC) systems working with the freescoo technology. The innovative freescoo concept is based on the use two fixed and cooled adsorption beds and advanced indirect evaporative cooling processes. The main feature of this new adsorption bed concept is to allow the simultaneous dehumidification and cooling of air. The systems analyzed have been installed in Italy last here and results based on field monitoring data are here presented. A description of the monitored systems and comparisons between the energy performances based on the main performance indicators such as EER, thermal COP, co…

Combining high performance thin layer chromatography with minispectrometer-fiber optic probe-coupled to smartphone for in place analysis: Lactose qua…

2021

ABSTRACT An in place colorimetric method has been proposed for estimation of the quantity of lactose in several matrix (milk, water effluents and surfaces). Analyzing the amount of this carbohydrate it can be control the product, the cleanliness of the parts of the dairy companies and it can avoid contamination of milk products produced there. This method combines the use of HPTLC for sugars separation with novel analytical devices as minispectrophotometer with fiber optic coupled to a smartphone. In order to measure the lactose a colorimetric reaction has been used. Variable volumes of samples or stock solutions were deposited in nano-silica gel layer, a mobile phase of acetonitrile:water:…

DIAGNOSIS-RELATED GROUP ANALYSIS AND STRATEGIC HEALTHCARE BUDGETING

2011

The term Diagnosis-Related Group DRG) refers to a classification system used to assess hospital services with the aim of streamling health care costs and improving performance. The DRG system focuses on the utilization of resources, and is not concerned with the specific type of care provided to the patient. This system highlights any diseconomies and eventual critical aspects of the hospital system. This article examines the variables used to correctly evaluate hospital performance based on the DRG system. These include: Average length of Stay, Average Daily Patients Load, Comparative Performance Index and Case Mix Index.

MODELLING AND ANALYSING STUDENT DROPOUT IN COLOMBIAN HIGHER EDUCATION THROUGH POLICY AND PUBLIC MANAGEMENT

The complexity of the phenomenon of student dropout in higher education requires several modeling techniques. In this doctoral dissertation, findings of blending mathematical, statistical and Dynamic Performance Management as modelling techniques are presented to allow a deeper comprehension of Colombian student dropout in higher education.

Overcoming traditional Performance Management in Public Healthcare Institutions: The need for a DPM Approach

Donabedian (1988) was the scientific father of the notion that Performance Measurement (PM) of hospital outputs leads to improved quality of healthcare services, setting the foundations of how hospital quality is still today defined, considered and measured using three different kinds of measures: structure, process and outcome measures. Nonetheless, a growing part of literature during the last two decades has started doubting those favourable outcomes of PM on hospital quality (De Vos, et al., 2009; Nolan & Berwick, 2006; Werner et al., 2008a, 2008b; Werner & Bradlow, 2006; Wright & Hershman, 2014) while other research shows that ineffective PM systems are not just useless but …

POLICY INNOVATION AND IMPLEMENTATION IN PUBLIC SECTOR: COMPLEXITIES, DYNAMICS AND UNCERTAINTIES

This research is expected to contribute to the knowledge base on how an effective impact assessment and adoption of innovations in the public sector could be facilitated. The need for trans-disciplinary assessment of the long-term potential impacts of innovation-driven policies may well be met with system dynamics as part of the dynamic performance management approach by way of modelling based simulation and analysis. Moreover, such analysis may contribute to learning and the accumulation of a knowledge repository that enables strategy developers, policy designers and decision makers to arrive at unexpected (often called counterintuitive) conclusions prior to policy implementation. Such ins…

The importance of the Logistics Performance Index in international trade

2014

Logistics and transport increasingly play a pivotal role in international trade relations. The Logistics Performance Index (LPI) analyses differences between countries in terms of customs procedures, logistics costs and the quality of the infrastructure for overland and maritime transport. The aim of this article is to analyse the impact that each of these components has on trade in emerging economies using a gravity model. Furthermore, the study also attempts to detect possible advances in logistics in developing countries, which are grouped into five regions (Africa, South America, Far East, Middle East and Eastern Europe) by comparing the first LPI data published in 2007 with the most re…

An Exploratory Study of Financial Performance in CEE Countries

2020

Our research investigates the performance of companies from Central and Eastern European (CEE) countries in the period after the Global Financial Crisis of 2007-2009 with the aim of identifying the driving factors behind accounting- and market-based performance. We include in the analysis companies from various industries in CEE countries that are European Union members and we study their performance between 2008-2016 over the following areas of performance:  liquidity,  solvency and indebtedness, operational profitability, global performance (through Return on assets and Return on equity), returns available to shareholders and market-based performance (through price/book value and Tobin Q …
