Query-Driven Method for Improvement of Data Warehouse Conceptual Model
2013
We propose a query-driven method that elicits the information requirements from existing queries on data sources and their usage statistics. Our method presumes that the queries against the source database reflect the analysis needs of users. We use this method to recommend changes to the existing data warehouse schemata. In our method, we take advantage of the schema versioning approach to reflect all changes that occur in the analysed process, and we analyse the activity of users in the source system, rather than changes in physical data structure, to infer the necessary improvements to the data warehouse schema.
Comparison of SQL Servers
2010
Šajā darbā apskatīti Microsoft SQL 2000, Microsoft SQL 2005 un Microsoft SQL 2008 serveri, veikta to vispārīgā un ātrdarbības salīdzināšana. Rezultātā tika noskaidrots, ka vairākums gadījumos Microsft SQL 2008 ir ātrāks par abiem pārējiem Microsoft SQL serveriem un tā funkcionalitāte ievērojami palīdz SQL pieprasījumu veidošanā.
Registered nurses' clinical reasoning in home healthcare clinical practice: A think-aloud study with protocol analysis.
2016
Abstract Background The home healthcare context can be unpredictable and complex, and requires registered nurses with a high level of clinical reasoning skills and professional autonomy. Thus, additional knowledge about registered nurses' clinical reasoning performance during patient home care is required. Objectives The aim of this study is to describe the cognitive processes and thinking strategies used by recently graduated registered nurses while caring for patients in home healthcare clinical practice. Design An exploratory qualitative think-aloud design with protocol analysis was used. Settings Home healthcare visits to patients with stroke, diabetes, and chronic obstructive pulmonary…
OPTIMAL AIRLINE SEAT INVENTORY CONTROL FOR MULTI-LEG FLIGHTS
2005
Abstract For large commercial airlines, efficiently setting and updating seat allocation targets for each passenger category on each multi-leg flight is an extremely difficult problem. This paper presents static and dynamic models of airline seat inventory control for multi-leg flights with multiple fare classes, which allow one to maximize an expected contribution to profit. The dynamic model uses the most recent demand and capacity information and allows one to allocate seats dynamically and anticipatory over time.
Locality of order-invariant first-order formulas
2000
A query is local if the decision of whether a tuple in a structure satisfies this query only depends on a small neighborhood of the tuple. We prove that all queries expressible by order-invariant first-order formulas are local.
DEFECT THEOREMS FOR TREES
2000
We generalize different notions of a rank of a set of words to sets of trees. We prove that almost all of those ranks can be used to formulate a defect theorem. However, as we show, the prefix rank forms an exception.
Locality of order-invariant first-order formulas

A query is local if the decision of whether a tuple in a structure satisfies this query only depends on a small neighborhood of the tuple. We prove that all queries expressible by order-invariant first-order formulas are local.

Hvordan påvirkes arbeidsprosesser ved innføring av EPJ og velferdsteknologi på sykehjem
2018
Masteroppgave i helse- og sosialinformatikk HSI500 - Universitetet i Agder 2018 In order to be better equipped in the challenges of the future, with an increasing number of elderly and fewer professionals to care for them, the government emphasizes the importance of service innovation in the healthcare sector. Change is required to gain socioeconomic benefits, particularly in work processes. More frequent and better use of electronic medical record (EMR) and welfare technology is necessary. The purpose of this study was to bring information and knowledge about how using technology in the nursing homes has transformed the work processes. Qualitative, exploratory method with semi-structured i…
Water erosion prediction by stochastic and empirical models in the Mediterranean: A case study in Northern Sicily (Italy)
2012
The present thesis aimed to explore the methodological advantages as well as limitations in applying different modelling approaches to predict water soil erosion in Mediterranean environments. The research was accomplished in the central northern part of Sicily (Italy), considering this region to be representative of Mediterranean environmental conditions. In this region soil degradation problems, due to water erosion are becoming more and more serious. Consequently, defining models being able to predict erosion susceptibility and to discriminate environmental factors causing erosion is important to protect soil resources. The prediction of the spatial distribution of soil erosion processes…
