Investigation of vehicle crash modeling techniques: theory and application
2013
Published version of an article in the journal: The International Journal of Advanced Manufacturing Technology. Also available from the publisher at: http://dx.doi.org/10.1007/s00170-013-5320-3 Creating a mathematical model of a vehicle crash is a task which involves considerations and analysis of different areas which need to be addressed because of the mathematical complexity of a crash event representation. Therefore, to simplify the analysis and enhance the modeling process, in this work, a brief overview of different vehicle crash modeling methodologies is proposed. The acceleration of a colliding vehicle is measured in its center of gravity—this crash pulse contains detailed informati…
The performance investigation of viscoelastic hybrid models in vehicle crash event representation
2011
Aurthor's version of a chapter published in the book: Proceedings of the 18th IFAC World Congress 2011. Also available from the publisher at: http://dx.doi.org/10.3182/20110828-6-IT-1002.00284 This paper presents application of physical models composed of springs, dampers and masses joined together in various arrangements to simulation of a real car collision with a rigid pole. Equations of motion of those systems are being established and subsequently solutions to obtained differential equations are formulated. We start with a general model consisting of two masses, two springs, and two dampers, and illustrate its application to represent fore-frame and aft-frame of a vehicle. Hybrid model…
A note on fair value accounting in a crisis: The influence of the hedge accounting regulations
2010
Published version of an article published in the journal: Business and Economics Journal. Also available from the publisher at: http://astonjournals.com/manuscripts/Vol2010/BEJ-13_Vol2010.pdf The role of fair value accounting in the financial crisis is contorversial and heavily debated. Some claim that fair value accounting of financial instruments contributed to the recent crisis. This note acknowledges that, in many industries, a significant proportion of the financial instruments are entered into for hedging purposes. I examine if a crisis through the hedge accounting regulations, can affect the overall use og fair value accounting in an economy. I present analytical evidence that the bo…

1H-naphtho[2,1-b]thiete and 2H-naphtho[2,3-b]thiete- synthesis and reactivity
1994
Abstract The title compounds 4 and 8 are obtained by flash vacuum pyrolysis of the corresponding hydroxymethylthionaphthols 3 and 7. Whereas 4 shows a smooth ring opening on heating, 8 is thermally stable but reacts photochemically. The different behavior is explained on the basis of an MNDO calculation. The valence isomers 4′ and 8′ represent thioquinonemethides, which are highly reactive components in [12π + 2π]cycloaddition processes (4 → 9, 10, 11; 8 → 12).

Miniproza un hipertekstu literatūra: kritiskās pieejas
2016
Bakalaura darba ietvaros tika analizēti un salīdzināti miniprozas un hipertekstu literatūras daiļdarbi – literārās formas, kuras mūsdienās kļūst arvien izplatītākas. Pētījuma mērķis bija atklāt vienojošās un atšķirīgās īpašības, kuras piemīt abu literatūras formu darbiem. Teorētiskā daļa sastāv no trijām nodaļām. Pirmajā nodaļā tika aprakstītas galvenās idejas un jēdzieni, kas ir saistīti ar miniprozu un hipertekstu literatūru. Otrajā nodaļā tika aprakstītas tās pašas idejas un jēdzieni, tikai papildus tika ņemti vērā pieredzējušu pētnieku uzskati un teorijas. Trešajā nodaļā tika īsumā aprakstīti pētāmie objekti. Praktiskajā daļā tika atsevišķi analizēti pētāmie objekti. Pētnieciskā darba r…
Balenciaga, the Master of Haute Couture
2020
This chapter deals with Balenciaga, a brand that carries the name of the designer known as “The Master of Haute Couture”, one of the most revered and influential fashion designers of the twentieth century. Characterized by sculptural quality, deft manipulation of textiles, and dramatic use of color and texture, Balenciaga creations are inspired by works of art and become works of art themselves through overlapping forms and genres. In this way, artification turns an elitist–but still commercial product—into a hybrid that acquires aesthetic and symbolic value and restores that aura lost due to production logics. Following this perspective, the main contribution of the chapter is to highlight…
Corporate social responsibility and managerial compensation: further evidence from spanish listed companies
2021
Ongoing regulatory efforts aim to link managerial compensation with a firm’s performance. However, little is known about whether and how Corporate Social Responsibility (CSR) goals are considered in the design of the managerial compensation scheme. This paper addresses this research question by analyzing a sample of Spanish listed firms for the period spanning 2013–2018. The outcomes of the regressions suggest that there is a positive relationship between CSR and the managerial compensation, but this relationship is significant only with lower levels of CSR. The study also reveals that CSR is positively associated with the proportion of equity-based compensation and, therefore, negatively a…
Reproduction of kinematics of cars involved in crash events using nonlinear autoregressive models
2012
Vehicle crashworthiness can be assessed by the variety of methods - the most common and direct one is a vehicle crash test. Visual inspection and obtained measurements, such as car acceleration, are used to examine impact severity of an occupant and overall car safety. However, those experiments are complex, time-consuming, and expensive. We propose a method to reproduce car kinematics during a collision using a feedforward neural network to estimate the system by use of nonlinear autoregressive (NAR) models. Specifically, feasibility of applying neural networks with an NAR model to the analysis of experimental data is explored by application to measurements of a vehicle crash test. This mo…
