'It’s about expecting the unexpected’: Live stand-up comedy from the audiences’ perspective

Copyright @ 2011 The Authors.A dearth of research exists that examines live stand-up comedy from the audiences’ perspective. This empirical article redresses this neglect by examining the appeal of live stand-up comedy to audiences and revealing their motivations for going to see live stand-up comedy. These interests are explored through an online survey and a series of semi-structured interviews with live stand-up comedy goers. The online survey uncovers the frequency of attending live stand-up comedy, the types of venues that stand-up comedy is seen in, the types of venues that audiences prefer to experience live stand-up comedy in, and the extent to which individuals attend live stand-up comedy alone or accompanied by others, and if so, who they attend with. The one-to-one semi-structured interviews extend the investigation by analysing the specific reasons why audiences attend live stand-up comedy. Five main themes emerge from the semi-structured interview data: respecting the stand-up comedian; expecting the unexpected; proximity and intimacy; opportunities for interaction; and sharing the comic experience. The article illustrates the differing ways in which audiences engage with live stand-up comedy at both the public and private level.Brunel University School of Social Science

F-15 digital electronic engine control system description

A digital electronic engine control (DEEC) was developed for use on the F100-PW-100 turbofan engine. This control system has full authority control, capable of moving all the controlled variables over their full ranges. The digital computational electronics and fault detection and accomodation logic maintains safe engine operation. A hydromechanical backup control (BUC) is an integral part of the fuel metering unit and provides gas generator control at a reduced performance level in the event of an electronics failure. The DEEC's features, hardware, and major logic diagrams are described

Amplified wind turbine apparatus

An invention related to the utilization of wind energy and increasing the effects thereof for power generation is described. Amplified wind turbine apparatus is disclosed wherein ambient inlet air is prerotated in a first air rotation chamber having a high pressure profile increasing the turbulence and Reynolds number thereof. A second rotation chamber adjacent and downstream of the turbine has a low pressure core profile whereby flow across the turbine is accelerated and thereafter exits the turbine apparatus through a draft anti-interference device. Interference with ambient winds at the outlet of the turbine apparatus is thus eliminated. Pivotable vanes controlled in response to prevailing wind direction admit air to the chambers and aid in imparting rotation. A central core may be utilized for creating the desired pressure profile in the chamber

Mechanical solar motor: A concept

Motor is proposed to convert radiation from sun directly into mechanical energy. Motor utilizes thermal expansion of liquid, heated by sun, as driving force. Unlike most thermally powered systems, it does not require that liquid be converted into vapor

The co-evolution of the “social” and the “technology": a netnographic study of Social movements in virtual worlds

Virtual worlds provide new forms of social interaction. They offer alternative spaces where social functions can be carried out in online three-dimensional virtual environments. One social phenomenon which has moved into the virtual world is the social movement, which are an important means of bringing out social, cultural and political changes through collective action. These social movements exist in an immersive technological ecosystem which is constantly evolving as designers release patches which change the way users “live” within these environments. Using a biography of artifacts approach, we explore not just the evolution of the technological artifact itself (the virtual world), but also its co-evolution with the social phenomena (a social movement). Using Netnography, a modified version of ethnography, and actornetwork theory, we explore a social movement in World of Warcraft, and observe how it evolves over time as changes to the virtual world are implemented

Mechanical thermal motor

An apparatus is described for converting thermal energy such as solar energy into mechanical motion for driving fluid pumps and similar equipment. The thermal motor comprises an inner concentric cylinder carried by a stationary core member. The core member has a cylindrical disc plate fixed adjacent to a lower portion and extending radially from it. An outer concentric cylinder rotatably carried on the disc plate defining a space between the inner and outer concentric cylinders. A spiral tubular member encircles the inner concentric cylinder and is contained within the space between the inner and outer cylinders. One portion is connected to the inner concentric cylinder and a second portion connected to the outer concentric cylinder. A heated fluid is conveyed through the tubular member and is periodically cooled causing the tubular member to expand and contract. This causes the outer concentric cylinder to reciprocally rotate on the base plate accordingly. The reciprocating motion of the outer concentric cylinder is then utilized to drive a pump member in a pump chamber

Test and evaluation of the HIDEC engine uptrim algorithm

The highly integrated digital electronic control (HIDEC) program will demonstrate and evaluate the improvements in performance and mission effectiveness that result from integrated engine-airframe control systems. Performance improvements will result from an adaptive engine stall margin mode, a highly integrated mode that uses the airplane flight conditions and the resulting inlet distortion to continuously compute engine stall margin. When there is excessive stall margin, the engine is uptrimmed for more thrust by increasing engine pressure ratio (EPR). The EPR uptrim logic has been evaluated and implemented into computer simulations. Thrust improvements over 10 percent are predicted for subsonic flight conditions. The EPR uptrim was successfully demonstrated during engine ground tests. Test results verify model predictions at the conditions tested

Real-time in-flight thrust calculation on a digital electronic engine control-equipped F100 engine in an F-15 airplane

Computer algorithms which calculate in-flight engine and aircraft performance real-time are discussed. The first step was completed with the implementation of a real-time thrust calculation program on a digital electronic engine control (DEEC) equiped F100 engine in an F-15 aircraft. The in-flight thrust modifications that allow calculations to be performed in real-time, to compare results to predictions, are presented
