The shape of an ROC curve in the evaluation of credit scoring models
PublicationThe AUC, i.e. the area under the receiver operating characteristic (ROC) curve, or its scaled version, the Gini coefficient, are the standard measures of the discriminatory power of credit scoring. Using binormal ROC curve models, we show how the shape of the curves affects the economic benefits of using scoring models with the same AUC. Based on the results, we propose that the shape parameter of the fitted ROC curve is reported...

Application of acoustic emission in evaluation of pitting corrosion insteel
PublicationPrzedstawiono przegląd różnych zastosowań emisji akustycznej (AE) w badaniach korozji wżerowej stali austenitycznej. Wykorzystanie emisji akustycznej w przypadku tego rodzaju korozji nie jest przypadkowe, ponieważ korozja wżerowa jest najgroźniejszym typem korozji, atakującym różne materiały konstrukcyjne takie jak stal. Prezentowana praca przeglądowa dostarcza przydatnych informacji o naturze pomiarów akustycznych, które wykazują...

Peculiarities of measurement uncertainty evaluation at calibrating a ring gauge
PublicationExample S13 from EA-4/02 M:2013 “Calibration of a ring gauge with a nominal diameter of 90 mm” is analyzed. The report uses the kurtosis method and the law of propagation of expanded uncertainty developed by the authors to the expanded uncertainty evaluation. It is shown that the introduction of a coaxiality correction for the ring gauge and the measuring axis of the comparator leads to the need to estimate its standard measurement...

Evolutionary Sets of Safe Ship Trajectories: Evaluation of Individuals
PublicationThe paper presents a description of the evaluation phase of the Evolutionary Sets of Safe Ship Trajectories method. In general, the Evolutionary Sets of Safe Ship Trajectories method combines some of the assumptions of game theory with evolutionary programming and finds an optimal set of cooperating trajectories of all ships involved in an encounter situation. While developing a new version of this method, the authors decided to...

Efficiency evaluation of graduation process in Australian public universities
PublicationFirst-year attrition and on-time graduation are key challenges for contemporary universities, which determine their efficiency. Based on the benefit of the doubt approach, this study reports the efficiency of the graduation process in 37 Australian public universities. The super-efficiency model extended by restrictions on virtual weights is used. The proposed model considers the attrition rate and the on-time graduation rate separately...

EVALUATION OF EFFECTIVENESS OF WATERJET PROPULSOR FOR A SMALL UNDERWATER VEHICLE
PublicationT he goal of the project described is to replace the existing propulsion system of a small underwater vehicle with a solution less prone to mechanical damage and ensuring a lower risk of the entanglement of fibrous objects suspended in the body of water. Four typical marine screws are utilised in the current design of the vehicle. One possible solution of the problem is the application of waterjet propulsors located...

Monolithic vs. Microservice Architecture: A Performance and Scalability Evaluation
PublicationContext. Since its proclamation in 2012, microservices-based architecture has gained widespread popularity due to its advantages, such as improved availability, fault tolerance, and horizontal scalability, as well as greater software development agility. Motivation. Yet, refactoring a monolith to microservices by smaller businesses and expecting that the migration will bring benefits similar to those reported by top global companies,...

Valuation method for operation of crankshaft-piston assembly in combustion engines in energy approach
PublicationPrzedstawiono propozycję wartościowania (ilościowego określenia) działania dowolnego układu korbowo-tłokowego silnika o zapłonie samoczynnym, w którym zachodzą oddziaływania energetyczne w określonym czasie. Działanie to rozumiane jest jako przekazywanie odbiornikowi energii w ustalonym czasie, w którym zachodzi przetwarzanie i przenoszenie energii w formie pracy i ciepła. Wartościowanie działania układów korbowo-tłokowych silników...

VALUATION OF EMBEDDED OPTIONS IN NON-MARKETABLE CALLABLE BONDS: A NEW NUMERICAL APPROACH
PublicationThe issue of how to price options embedded in callable bonds has attracted a lot of interest over the years. The usual bond valuation methods rely on yield curves, risk premium, and other parameters to estimate interest rates used in discounted cash flow calculations. The option to retire the bond is, however, neglected in the standard pricing models, causing a systematic overvaluation of callable bonds. In the event of a decline...

Daytime Acute Non-Visual Alerting Response in Brain Activity Occurs as a Result of Short- and Long-Wavelengths of Light
PublicationVery recent preliminary findings concerning the alerting capacities of light stimulus with long-wavelengths suggest the existence of neural pathways other than melatonin suppression that trigger the nonvisual response. Though the nonvisual effects of light during the daytime have not been investigated thoroughly, they are definitely worth investigating. The purpose of the present study is to enrich existing evidence by describing...

Celebrities’ personal brand authenticity in social media: an application in the context of football top-players. The Robert Lewandowski case
PublicationThe aim of the study is to explore personal brand authenticity in social media through sentiment analysis. A survey has been conducted in the context of football players with respect to Robert Lewandowski – the most valuable Polish football-celebrity brand. Authors first assess antecedents of his brand authenticity basing on an international sample of social media users, made of 219 cases from 22 countries (intentionally excluding...

Distributed Evacuation in Graphs with Multiple Exits
PublicationWe consider the problem of efficient evacuation using multiple exits. We formulate this problem as a discrete problem on graphs where mobile agents located in distinct nodes of a given graph must quickly reach one of multiple possible exit nodes, while avoiding congestion and bottlenecks. Each node of the graph has the capacity of holding at most one agent at each time step. Thus, the agents must choose their movements strategy...

Measurement accuracy evaluation of transmission line earthings by impulse tests
PublicationUziemienia słupów linii energetycznych powinny być sprawdzane okresowo. Pomiary rezystancji takich uziemień przy pomocy metody niskoczęstotliwościowej wymaga wyłaczania linii i odkręcania przewodów odprowadzających od konstrukcji słupa. Metoda udarowa jest znacznie łatwiejsza w tej aplikacji i nie wymaga wyłaczania linii na czas pomiarów. W pracy oszacowano wpływ uziemień sąsiednich słupów na dokładność pomiarów metodą udarową.
