A PC parallel port button box provides millisecond response time accuracy under Linux
No full textFor psychologists, it is sometimes necessary to measure people's reaction times to the nearest millisecond. This article describes how to use the PC parallel port to receive signals from a button box to achieve millisecond response time accuracy. The workings of the parallel port, the corresponding port addresses, and a simple Linux program for controlling the port are described. A test of the speed and reliability of button box signal detection is reported. If the reader is moderately familiar with Linux, this article should provide sufficient instruction for him or her to build and test his or her own parallel port button box. This article also describes how the parallel port could be used to control an external apparatus
Globalization, Tax Erosion and the Internet
No full textElectronic commerce and globalization are, and will continue to be a challenge to tax collectors throughout the world. Globalization makes the cross-border movements in goods, capital and labour less transparent. Companies and individuals are therefore able to exploit tax differences between countries. The Internet eliminates borders between countries and furthermore makes businesses virtually invisible. At the consumer end, E-commerce makes the tracing of transactions and thus the taxing of goods and services sold and distributed via the Internet almost impossible. As a result, state and national governments’ tax bases are, or are at risk of, being eroded.public economics ;
Millisecond accuracy video display using OpenGL under Linux
No full textTo measure people’s reaction times to the nearest millisecond, it is necessary to know exactly when
a stimulus is displayed. This article describes how to display stimuli with millisecond accuracy on a
normal CRT monitor, using a PC running Linux. A simple C program is presented to illustrate how this
may be done within X Windows using the OpenGL rendering system. A test of this system is reported
that demonstrates that stimuli may be consistently displayed with millisecond accuracy. An algorithm
is presented that allows the exact time of stimulus presentation to be deduced, even if there are relatively
large errors in measuring the display time

High efficiency implementation of PC and PC stable algorithms yields three-dimensional graphs of information flow for the Earth' atmosphere
No full textSeptember 3, 2014.Causal discovery algorithms have recently been applied to several climate applications. In particular, in prior work we have developed methods to recover pathways of interaction in the global climate system, using the classic PC algorithm. However, standard implementations of the PC algorithm cannot handle the large number of variables and temporal models required for this application. This technical report shows that a more efficient implementation of the PC algorithm can provide speed gains of a factor of 1,000 or more. This in turn enables us to calculate graphs of information flow with much higher resolution grids. Furthermore, we can now - for the first time ever - calculate information flow graphs that extend over three dimensions, i.e. rather than just including one layer of the planet's atmosphere we can now capture interactions across several height layers

<Theoretical Article>Death Rules: A Survey and Analysis of PC Death in Tabletop Role-Playing Games
No full textIn this paper, we define and explore player character (PC) death in tabletop role-playing games (TRPGs) through a survey of how PC death is addressed in a range of TRPG rulebooks. We connect PC death to player agency and in doing so connect death to downtime and other play modes in which players have less or no control of their PCs. We discuss how PC death affects gameplay by breaking up time, by ending or starting a period of play, or by reinforcing or severing player and PC connections. The objective of this analysis is to improve our understanding of PC death, as well as PC life and the control, agency and play associated with it.本稿では, テーブル・トーク・ロールプレイング・ゲーム(TRPG)におけるプレイヤーキャラクター(PC)の死を定義し, 様々なTRPGルールブックでPCの死がどのように扱われているかを調査することを考察する. また, PCの死をプレイヤーの行動力と結びつけ, ダウンタイムや, 自分のPCのコントロールが少ない, あるいはPCをコントロールできない他のプレイモードと結びつけている. PCの死が時間の中断, プレイの終了や開始, プレイヤーとPCのつながりの強化や切断によってゲームプレイにどのような影響を与えるかについても考察する. PCの死だけでなく, PCの人生とそれに関連するコントロール, エージェンシー(行為主体性), プレイについての理解を深めることが本稿の分析の目的である
Degradation of bisphenol-a-polycarbonate (BPA-PC) optical lenses under simulated harsh environment conditions
No full textThis paper investigates degradation and failure mechanisms of BPA-PC lenses in simulated harsh environment conditions. Exposure of secondary optics in Light Emitting Diode LED-based systems or any other similar applications to environmental stresses can adversely effect the performance and lifetime of products. This paper simulates a harsh environment condition, using a salt bath oven. Salt spray exposure/ageing tests at 45° C were carried out up to four months. Fourier transform infrared-attenuated total reflection FTIR-ATR spectrometer and Lambda 950 Ultraviolet-Visible (UV-VIS) spectrophotometer were used to study the optical and chemical characteristics of aged plates. Results showed that salt bath exposure test resulted in the severe deterioration of optical characteristics BPA-PC samples. Degradation of optical properties of BPA-PC plates is attributable to the oxidation of samples.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Electronic Components, Technology and Material
