This article focuses on a new amusement ride that blends several control systems by combining spinning-coaster thrills with interactive special effects. The Exterminator at Kennywood Amusement Park combines a ‘wild mouse’ coaster with the interactivity of a dark ride. ‘Dark ride’ is amusement maker parlance for fun house style frights that pop into view unexpectedly. A proximity sensor, positioned after the coaster and animation went in, begins the action sequence for this figure just as the riders come upon it. Bringing the Exterminator up to speed was a matter of controlling the coaster, controlling the animation, and controlling the interaction between the two independent systems. A process of trial and error, determining the right moment to start an event occurs only after the animation is in place and the carts are riding the rails. A double pneumatic fin brake below the track slows carts as needed before they enter the boiler.

Does humanity progress primarily through leaders organizing and directing followers, or through trial and error by individuals free to chart their own path? For most of human history ruling classes had the capacity and the desire to tightly regiment society, to the general detriment of progress. But beginning in the 1500s, Europeans developed a series of arguments for simply leaving well enough alone. First in the form of the scientific method, then in the form of free expression, and finally in the form of the continuously, spontaneously reordered free market, people began to accept that progress is hard, and requires that an immense number of mistakes be tolerated so that we may learn from them. This book tells the story of the development of these three ideas, and for the first time tells of the mutual influence among them. It outlines the rise, and dramatic triumph, of each of these self-regulating systems, followed by a surprising rise in skepticism, especially in the economic context. Such skepticism in the 20th century was frequently costly and sometimes catastrophic. Under the right conditions, which are more frequent than generally believed, self-regulating systems in which participants organize themselves are superior. We should accept their turbulence in exchange for the immense progress they generate.

ReAction! gives a scientist's and artist's response to the dark and bright sides of chemistry found in 140 films, most of them contemporary Hollywood feature films but also a few documentaries, shorts, silents, and international films. Even though there are some examples of screen chemistry between the actors and of behind-the-scenes special effects, this book is really about the chemistry when it is part of the narrative. It is about the dualities of Dr. Jekyll vs. inventor chemists, the invisible man vs. forensic chemists, chemical weapons vs. classroom chemistry, chemical companies that knowingly pollute the environment vs. altruistic research chemists trying to make the world a better place to live, and, finally, about people who choose to experiment with mind-altering drugs vs. the drug discovery process. Little did Jekyll know when he brought the Hyde formula to his lips that his personality split would provide the central metaphor that would come to describe chemistry in the movies. This book explores the two movie faces of this supposedly neutral science. Watching films with chemical eyes, Dr. Jekyll is recast as a chemist engaged in psychopharmaceutical research but who becomes addicted to his own formula. He is balanced by the often wacky inventor chemists who make their discoveries by trial-and-error.

In this article I explore the relationship between laugh responses and the turns which they orient to. I consider whether it is possible to identify properties of the prior turns that the recipient may be orienting to in laughing. Thus, I begin by briefly exploring the relationship between laughter and humour in interaction. But I point to some of the difficulties in identifying what it is that makes some discourse humorous, and I argue that laughter is not simply a reaction to the perception of humour. Laughter should be considered as an action in its own right, the occurrence of which may have nothing to do with the presence of humour. Consequently, I consider the notion of the “laughable” and whilst I agree that “(v)irtually any utterance or action could draw laughter, under the right (or wrong) circumstances” (Glenn 2003: 49), I argue it is often possible to identify recurrent properties of turns treated as laughables. These properties concern the design, action and the sequential position of the turns. Thus, it seems that speakers draw from a range of resources in constructing laughables. I illustrate this by exploring a collection of instances of figurative phrases followed by laugh responses from telephone calls. I argue that in responding with laughter, recipients may orient to a cluster of properties in the prior turn. However, because laughter is an action with its own sequential implications, rather than simply a response to a prior turn, whether a recipient orients to a prior candidate laughable by laughing will depend on the nature of his or her contribution to the action sequence.

Abstract A method for automated mask-layout and process synthesis for MEMS is presented. The synthesis problem is approached by use of a genetic algorithm. For a given desired device shape, and several fabrication process choices, this synthesis method will produce one or more mask-layouts and associated fabrication process sequences (which when used can generate shapes close to the desired one). Given complicated device shapes and wide range of fabrication process possibilities, the designer may encounter difficulty producing the right mask-layout and fabrication procedure by experience and trial and error. An automated synthesis tool like this will be helpful to the designer by increasing the efficiency and accuracy of the design of MEMS devices.

A safety device is proposed that will enable the operator of a sit-down rider forklift to discharge a self-dumping hopper while seated at the control station. Dumping proceeds without ground personnel which removes them from traffic flow and protects them from impacting loads that overspill the hopper, roll, bounce, or are accidentally discharged from the hopper. Just the right amount of rearward mast tilt is normally required to overcome the latching resistance of heavily loaded forward biased hoppers without becoming relatched when the trip lever is released. The associated trial and error balancing procedure is eliminated together with any need for muscling the latch rod. Unlatching poles are no longer used for elevated dumping.

This chapter discusses the eight principles of the ATT. Article 5(1) requires parties to implement the treaty while bearing in mind the principles set out. The principles cover the following issues: the right of states to self-defence; the settlement of international disputes by peaceful means; refraining from the threat or use of force against the territorial integrity or political independence of any state; non-intervention in matters essentially within the domestic jurisdiction of a state; respecting and ensuring respect for international humanitarian law and human rights; the responsibility of states to regulate international trade in conventional arms and prevent diversion and to establish national control systems; respect for the interests of states to acquire, produce, export, import, and transfer conventional arms; and implementation of the ATT in a consistent, objective, and non-discriminatory manner.

The paper discusses conventional modes of presenting axial and radial compressor operating envelopes and the conditions under which changes of factors such as the polytropic index n and the Reynolds number Re are negligible. It is shown on the basis of operating envelopes under what conditions compressors will surge (erratic flow conditions or stalling). In axial or radial compressor installations, surging can only be controlled by shifting the operating point in the operating envelope to the right away from the surge limit line. One method of doing this is to open the bypass valve to recycle part of the gas from the discharge piping to the suction piping. The paper describes in detail the control system required and discusses universal and simplified control systems. Modifications of control systems to fit, for example, wide suction pressure ranges are studied. The paper concludes with an investigation of methods of providing for high surge control reliability.

An interactive Fortran IV program is described which allows the orientation matrix of a crystal to be determined and refined without ambiguity, from a transmission or reflection Laue photograph. The indexing method is that of Riquet & Bonnet [J. Appl. Cryst. (1979), 12, 39–41] applied to a small number of data (less than ten) and adapted for interactive use. The verification of calculated solutions or even the trial-and-error search for the right solution is made by means of the visual comparison between the experimental diagram and simulated patterns displayed on a graphic screen. In addition, the rotation angles for setting the crystal to any new orientation may be computed.
