Academic literature on the topic 'Clutches (Machinery) Noise'

The essay introduce the hardware Design based on the Line detection system, and apply the wavelet analysis theory to the low clutch’s fault signal processing to fulfill the low clutch’s noise detection which based on the wavelet transform. Practice shows that the continuous wavelet signal has a strong ability of fault detection, if reasonable choice of wavelet function and various parameters among the fault detection, the local feature of the fault signal can be intuitively got, thus supply the products with a effective tool. The current washing machine clutch all have a washing deceleration function, so it is called as low clutch. As one of the most common parts of rotating machinery, low clutch is also one of the easily damaged parts among the rotating machinery. According to statistics, thirty percent of the rotating machinery’s operational problems caused by the bearing faults[1]. Bearing defects can cause severely machine vibration and generation noise, or even cause damage to the equipment[4]. This article is mainly detect the low clutch’s vibration noise in operation by accelerometer, and deal with the collected data through wavelet transform, thus realize the On-line condition monitoring to the low clutch.

The technical development of tractor designs is characterized by an increase in the power of consumers, the use of electric drive units. The load on the electric system of a modern tractor is constantly growing and exposes the existing 12-volt systems to excessive loading. To date, with the relatively low efficiency of traditional generators it is impossible to meet the growing needs of tractors and its systems. The solution of the problem of increasing the power simultaneously with increasing the efficiency (up to 85...90 %) could become an integrated starter-generator. Possessing sufficient power in the propulsion mode (up to 8 kW), the starter generator makes it possible to improve the starting and energy characteristics of the internal combustion engines of the tractor. The proposed design of electrical machines is located between the engine cylinder assembly and the tractor clutch. The adopted configuration allows to transfer considerable power in both directions, improves the starting qualities of diesel engines of tractors, and also realize the functions of damping the torsional oscillations of the crankshaft, which significantly reduces the noise and vibration of the engine. Based on the results of the study, the choice of a starter-generator device based on a valve motor is justified in connection with diesel engines of universal tractors of traction class 1,4 and a scheme for its placement in the clutch housing without changing its basic design has been developed. The advantage of the proposed design is the use of electric machines to start the engine, which in this case is switched to the electric motor mode and switches to the generator mode during operation, providing power to the on-board network. In addition, combining the starter and generator in a single unit simplifies the design, reduces the cost of manufacturing and assembly, which is an advantage in terms of production costs, replacing the starter and generator and on some tractors the starting piston engine.

Cars crest the rise behind the truck stop and drop cones of light over the highway. Ryan dunks his head under a tap. He rubs red dust from his pores and tries to drink some water, but it slides down his throat like a length of wire.His older brother Josh fills their drink bottles. “Wanna get some chips or something?”Ryan shakes his head. He’s sick of watching Josh’s pulpy tongue poke his broken tooth. Their dad never left visible marks before—Ryan used to wish for a cut or bruise, so someone at school could see it. He shivers and clutches his coat tight. Josh says, “We got money.”Ryan wonders how Josh stole it. He didn’t know there was anything to steal. He stares back down the road.“Fine, fuck, I’ll get—”Ryan nudges him and he looks over his shoulder. A square silhouette approaches. The brothers stand back as a two-storey house pulls up in front of them, strapped to the back of a truck. The house is cut in half, patched with pale afterimages of furniture and light fittings. A door slams and a tattooed man with a white wedge of beard climbs out of the cabin. He stretches and heads for the toilets. Josh sidles up to the house and runs his hands along the straight, fresh edge of the floorboards. Sawdust settles onto his hoodie. He laughs and hurls his bag into one of the rooms. “Shit yeah. You coming?” Ryan hesitates. He remembers the time Josh’s Torana—a windowless wreck, used for drifting in paddocks and chasing kangaroos—broke down at the back of their property. Ryan and their dad towed Josh in the four-wheel drive while he sat in the Torana, steering with his knees. He started swinging wide, bouncing the back of the car off tree trunks, until he overshot and hit an old gum headfirst. The cable snapped, jerking the four-wheel drive to a halt. Ryan’s head smacked against the dash. Josh emerged from the smoking Torana with a bloody nose, laughing hysterically—thumping the bonnet and laughing hysterically—even after his dad came over and hit him on the back of the head. Through a window in the far wall they watch the driver eat a sausage roll. Ryan follows Josh upstairs and they stand on the edge of the second floor, where the distorted acoustics amplify the traffic sounds. From this angle, the outback barely conceals the curvature of the earth. The moon is a globe of bone amongst the clouds, a ball and socket. Ryan thinks they’re in a kid’s bedroom; a mural on the far wall depicts the bottom of the ocean and a tinted window spreads faded colours on the floor. He tries to imagine the room with all its walls in place. The brothers hide in a back room when they hear the driver's footsteps. The driver slides a torch over the house and light filters through the floorboards in front of them. They press themselves against the wall. Ryan starts shivering again and Josh elbows him in the ribs. The truck eases onto the road and the house groans, its unsupported floorboards dipping and lifting like piano keys. Signs and lights flick past. The brothers creep downstairs, struggling to stay upright on the vibrating staircase. Josh opens two tins of baked beans. A string of cold sauce as thick as an artery spills down Ryan’s neck. They place the empty tins on the floor and bet on which one will roll off the edge first. Josh wins. He grabs Ryan’s head and rubs his knuckles into it. Josh runs into the bathroom, which juts out over the edge of the trailer. Ryan hangs back in the doorway. Instead of a toilet Josh finds a small circle cut out of the floor. He steadies himself and pisses in it. Ryan sprints into the other room and pisses out the window. They laugh and piss until a horn blares behind them. Ryan ducks. Urine splatters on the sill. He scrabbles with his pants. He’s pissed on someone’s windscreen. The horn’s still going. Headlights hit the trees beside him. Josh comes in from the toilet and Ryan grabs him and pulls him to the ground. A four-wheel drive appears beside them. There’s barely enough room on the road; the truck swerves away and a branch scrapes along the roof of the house. The passengers hang out the windows, screaming abuse. Josh stumbles onto his feet and gives them the finger. Someone hurls an empty coke can and it lands on the second floor. Then the car is gone and only the wind remains, filling the house with the whining roar of a depressurised aircraft. The trees are a smear of static. Josh smacks Ryan on the back of the head. Ryan swings instinctively. Josh deflects his fist and knocks him to the floor and Ryan’s head hits the skirting board. Something crumbles. Ryan presses his thumb into Josh’s black eye and Josh twists his arm behind his back. When they were kids Josh pinned Ryan in this position and shoved gravel into his mouth. Ryan remembers the stones scratching his teeth, the bloody mud he spat out. Josh lets him up and Ryan scrambles into the corner, sick with sudden panic. He kicks his bag away. Josh wipes his mouth and laughs. He crouches down and stares at the spot where Ryan’s head hit the wall. One of the panels has collapsed inwards. Josh snorts. “Look what your fucking head did!” He pulls out the panel and tosses it onto the road. He shines his torch into the space behind it, brushes away the cobwebs and extracts a cheap gold box. “Well, well, well,” he mutters. He sets it on the ground and dusts the lid off. He tries to pry it open it but it’s locked. Ryan looks over. Josh grips the box in both hands and pulls. For a moment his top teeth dig into his lip and then the box bursts open, scattering pieces of silver. Ryan reaches out his hand, expecting jewellery, but he jerks it back when he finds a razor near his foot. The floor is littered with needles and knives. Josh picks up a brown glass bottle and squints at the label. “Iodine.” They stare at the blades in silence. A sand bank slides past as steadily as a sine wave. Josh carves the word FUCK into the floor with a scalpel. Ryan cringes but doesn’t dare warn him about diseases. On long-distance drives Ryan often stares out the window and imagines his vision is a laser-beam, cutting cleanly through cities, forests, passers-by. Now he pictures a wrecking ball swinging into the darkness and colliding with a run-down rollercoaster. He imagines the ball smashing through the tangle of struts and tracks; wrapping around and around a corkscrew section like a yoyo; sending a train of carriages hurtling through the remains of a loop. A few hours later the house passes through a town surrounded by silos and steel windmills. The brothers retreat to the mural room. Streetlights slide on and off them: orange, black, orange, black, orange, black. Josh waves at the people on the balcony of the pub. In a slouched house over a hardware store Ryan glimpses, through half-closed curtains, a topless woman sitting on the edge of a bed, combing her hair. He tries to make out the name of the town on the shopfronts. Josh lights a joint, indifferent. Ryan slides his torch over the door frame, which is marked with the family’s heights. The vibrations blur the words, but he makes out the name “Molly” at eye level. He wonders if this is her room. He stares at the underwater scene and remembers reading somewhere that squids lay eggs via a funnel under their eyes, so their offspring emerge like hard, heavy tears. Josh offers the joint to Ryan, who snatches it and takes a shallow drag. Josh brushes dandruff off his sleeves. Ryan drops the joint when a siren starts to wail: they scramble to their feet and run over to the back window, fearing the police, but the road’s empty. Josh looks up and shouts, “Smoke detector!” Ryan starts waving his jacket to clear the smoke, but Josh just rips the detector from the ceiling and hurls it into a dam beside the road. Once the houses thin out the brothers climb back downstairs and unroll their sleeping bags. Ryan uses his pack as a pillow but Josh’s is still full of tins. Dark branches clasp the stars. Ryan gets up and tugs at his penis in the toilet, watching the bitumen slide under the hole like a belt sander. He tries to remember the scene above the hardware store—the line of tea lights on the windowsill, the mosquito net over the bed, the woman’s small, pale breasts—but his mind keeps replaying the image of a young girl pressing a razor into her thigh. They're woken a few hours later by footsteps. Ryan opens his eyes. Josh is already on his feet. “What the hell is that?” The ceiling creaks again and Josh picks up the torch and the scalpel. “I'm gonna take a look.” They creep upstairs. The hall is empty. Something shuffles in one of the rooms and slams against the wall. Josh whispers, “There ain’t no doors on that side of the hall. The fucking door's in the other half of the house.' He grabs the end of the wall and leans out, struggling to see around it. The wind blasts him back and he cups his hands over his black eye. He pushes the torch into Ryan’s chest. “Go. You go.” Ryan tries to turn away but Josh blocks him and says, “Don’t be a dickhead. Just see what’s over there.” The dark, crinkled skin around his eye shines with tears. “Fuck’s sake, my eye’s killing me. I can’t go.” He pushes Ryan again. With his free hand Ryan feels for the frame behind the plaster. He swings his leg around the wall, plants his foot on the other side, presses his chest against the end of the wall and edges into the other room. It’s empty. Sliding doors in the far wall conceal a walk-in wardrobe. A door on the right leads to an en suite. His foot crunches on the coke can and he kicks it onto the road. He pushes the bathroom door open and the torch beam slides over the tiles. He glimpses movement behind him in the mirror, but it’s only the trees. The tiles remind him of the killing floor on their chicken farm. When he and Josh were little their dad just cut the chickens’ heads off with an axe and let them run around spurting blood out of their necks, but a few years ago he got new machinery installed. Now the chickens were strung up by their feet on an overhead conveyor belt that carried them to a trough filled with electrified water, which killed them as soon as their heads hit it. He walks back into the bedroom and stares at the sliding doors. “Oi hurry up!” Josh shouts from the hall. “Fuck you.” “Fuck you, dickhead!” Ryan pushes a sliding door open and shines his torch in. A man crouches in the darkness, gripping a bottle of colourless liquid in both hands. His clothes are stuffed with newspapers; his beard clings to his chin like clotted blood caked together. He stares at Ryan and shouts, “Bastards! Leave me alone ya bastards! Get outta here! Get out!” He hurls the bottle and it smacks into Ryan’s shoulder. The bottle smashes on the floor; shards of glass cascade onto the highway. The man stumbles out of the wardrobe, lunging at Ryan, grabbing at his jacket. Ryan reaches around the wall and Josh pulls him over. The man slams his fists rhythmically, like pistons, into the other side of the wall. They scramble downstairs and Ryan takes off his jacket and waves it over the edge, screaming to get the driver’s attention. He looks up and sees the man shouting at him, tears streaming sideways across his face. Josh pulls Ryan back but he struggles free. Ryan crouches near the edge and stares at the scrub racing past. There’s a hill ahead and the truck’s slowing down. Josh sees what he’s thinking and calls him an idiot, but he’s already leaning forwards, judging the distance, waiting for the driver to downshift. Josh grabs him by the collar and hisses something but he doesn’t listen and pulls away and jumps. His head smacks solidly against a root and his arm twists under his torso, grinding into the gravel. He lies on his back and spits out black dust. Blood dribbles out of his arm. When the house reaches the top of the hill something flies out and bounces along the side of the road. Ryan gets to his feet and limps towards it. He searches through the bushes and finds his bag with half the tins in it. The roof of the house disappears over the top of the hill and he imagines Josh reaching his destination, perhaps a few hours after dawn, on a small hill out in the bush somewhere, where the morning light is as sallow as blood plasma and the other half of the house is already waiting.

By the time you read this, it will be wrong. Things seemed to be moving so fast in these first days after airplanes crashed into the World Trade Center, the Pentagon, and the Pennsylvania earth. Each certainty is as carelessly dropped as it was once carelessly assumed. The sounds of lower Manhattan that used to serve as white noise for residents—sirens, screeches, screams—are no longer signs without a referent. Instead, they make folks stare and stop, hurry and hustle, wondering whether the noises we know so well are in fact, this time, coefficients of a new reality. At the time of writing, the events themselves are also signs without referents—there has been no direct claim of responsibility, and little proof offered by accusers since the 11th. But it has been assumed that there is a link to US foreign policy, its military and economic presence in the Arab world, and opposition to it that seeks revenge. In the intervening weeks the US media and the war planners have supplied their own narrow frameworks, making New York’s “ground zero” into the starting point for a new escalation of global violence. We want to write here about the combination of sources and sensations that came that day, and the jumble of knowledges and emotions that filled our minds. Working late the night before, Toby was awoken in the morning by one of the planes right overhead. That happens sometimes. I have long expected a crash when I’ve heard the roar of jet engines so close—but I didn’t this time. Often when that sound hits me, I get up and go for a run down by the water, just near Wall Street. Something kept me back that day. Instead, I headed for my laptop. Because I cannot rely on local media to tell me very much about the role of the US in world affairs, I was reading the British newspaper The Guardian on-line when it flashed a two-line report about the planes. I looked up at the calendar above my desk to see whether it was April 1st. Truly. Then I got off-line and turned on the TV to watch CNN. That second, the phone rang. My quasi-ex-girlfriend I’m still in love with called from the mid-West. She was due to leave that day for the Bay Area. Was I alright? We spoke for a bit. She said my cell phone was out, and indeed it was for the remainder of the day. As I hung up from her, my friend Ana rang, tearful and concerned. Her husband, Patrick, had left an hour before for work in New Jersey, and it seemed like a dangerous separation. All separations were potentially fatal that day. You wanted to know where everyone was, every minute. She told me she had been trying to contact Palestinian friends who worked and attended school near the event—their ethnic, religious, and national backgrounds made for real poignancy, as we both thought of the prejudice they would (probably) face, regardless of the eventual who/what/when/where/how of these events. We agreed to meet at Bruno’s, a bakery on La Guardia Place. For some reason I really took my time, though, before getting to Ana. I shampooed and shaved under the shower. This was a horror, and I needed to look my best, even as men and women were losing and risking their lives. I can only interpret what I did as an attempt to impose normalcy and control on the situation, on my environment. When I finally made it down there, she’d located our friends. They were safe. We stood in the street and watched the Towers. Horrified by the sight of human beings tumbling to their deaths, we turned to buy a tea/coffee—again some ludicrous normalization—but were drawn back by chilling screams from the street. Racing outside, we saw the second Tower collapse, and clutched at each other. People were streaming towards us from further downtown. We decided to be with our Palestinian friends in their apartment. When we arrived, we learnt that Mark had been four minutes away from the WTC when the first plane hit. I tried to call my daughter in London and my father in Canberra, but to no avail. I rang the mid-West, and asked my maybe-former novia to call England and Australia to report in on me. Our friend Jenine got through to relatives on the West Bank. Israeli tanks had commenced a bombardment there, right after the planes had struck New York. Family members spoke to her from under the kitchen table, where they were taking refuge from the shelling of their house. Then we gave ourselves over to television, like so many others around the world, even though these events were happening only a mile away. We wanted to hear official word, but there was just a huge absence—Bush was busy learning to read in Florida, then leading from the front in Louisiana and Nebraska. As the day wore on, we split up and regrouped, meeting folks. One guy was in the subway when smoke filled the car. Noone could breathe properly, people were screaming, and his only thought was for his dog DeNiro back in Brooklyn. From the panic of the train, he managed to call his mom on a cell to ask her to feed “DeNiro” that night, because it looked like he wouldn’t get home. A pregnant woman feared for her unborn as she fled the blasts, pushing the stroller with her baby in it as she did so. Away from these heart-rending tales from strangers, there was the fear: good grief, what horrible price would the US Government extract for this, and who would be the overt and covert agents and targets of that suffering? What blood-lust would this generate? What would be the pattern of retaliation and counter-retaliation? What would become of civil rights and cultural inclusiveness? So a jumble of emotions came forward, I assume in all of us. Anger was not there for me, just intense sorrow, shock, and fear, and the desire for intimacy. Network television appeared to offer me that, but in an ultimately unsatisfactory way. For I think I saw the end-result of reality TV that day. I have since decided to call this ‘emotionalization’—network TV’s tendency to substitute analysis of US politics and economics with a stress on feelings. Of course, powerful emotions have been engaged by this horror, and there is value in addressing that fact and letting out the pain. I certainly needed to do so. But on that day and subsequent ones, I looked to the networks, traditional sources of current-affairs knowledge, for just that—informed, multi-perspectival journalism that would allow me to make sense of my feelings, and come to a just and reasoned decision about how the US should respond. I waited in vain. No such commentary came forward. Just a lot of asinine inquiries from reporters that were identical to those they pose to basketballers after a game: Question—‘How do you feel now?’ Answer—‘God was with me today.’ For the networks were insistent on asking everyone in sight how they felt about the end of las torres gemelas. In this case, we heard the feelings of survivors, firefighters, viewers, media mavens, Republican and Democrat hacks, and vacuous Beltway state-of-the-nation pundits. But learning of the military-political economy, global inequality, and ideologies and organizations that made for our grief and loss—for that, there was no space. TV had forgotten how to do it. My principal feeling soon became one of frustration. So I headed back to where I began the day—The Guardian web site, where I was given insightful analysis of the messy factors of history, religion, economics, and politics that had created this situation. As I dealt with the tragedy of folks whose lives had been so cruelly lost, I pondered what it would take for this to stop. Or whether this was just the beginning. I knew one thing—the answers wouldn’t come from mainstream US television, no matter how full of feelings it was. And that made Toby anxious. And afraid. He still is. And so the dreams come. In one, I am suddenly furloughed from my job with an orchestra, as audience numbers tumble. I make my evening-wear way to my locker along with the other players, emptying it of bubble gum and instrument. The next night, I see a gigantic, fifty-feet high wave heading for the city beach where I’ve come to swim. Somehow I am sheltered behind a huge wall, as all the people around me die. Dripping, I turn to find myself in a media-stereotype “crack house” of the early ’90s—desperate-looking black men, endless doorways, sudden police arrival, and my earnest search for a passport that will explain away my presence. I awake in horror, to the realization that the passport was already open and stamped—racialization at work for Toby, every day and in every way, as a white man in New York City. Ana’s husband, Patrick, was at work ten miles from Manhattan when “it” happened. In the hallway, I overheard some talk about two planes crashing, but went to teach anyway in my usual morning stupor. This was just the usual chatter of disaster junkies. I didn’t hear the words, “World Trade Center” until ten thirty, at the end of the class at the college I teach at in New Jersey, across the Hudson river. A friend and colleague walked in and told me the news of the attack, to which I replied “You must be fucking joking.” He was a little offended. Students were milling haphazardly on the campus in the late summer weather, some looking panicked like me. My first thought was of some general failure of the air-traffic control system. There must be planes falling out of the sky all over the country. Then the height of the towers: how far towards our apartment in Greenwich Village would the towers fall? Neither of us worked in the financial district a mile downtown, but was Ana safe? Where on the college campus could I see what was happening? I recognized the same physical sensation I had felt the morning after Hurricane Andrew in Miami seeing at a distance the wreckage of our shattered apartment across a suburban golf course strewn with debris and flattened power lines. Now I was trapped in the suburbs again at an unbridgeable distance from my wife and friends who were witnessing the attacks first hand. Were they safe? What on earth was going on? This feeling of being cut off, my path to the familiar places of home blocked, remained for weeks my dominant experience of the disaster. In my office, phone calls to the city didn’t work. There were six voice-mail messages from my teenaged brother Alex in small-town England giving a running commentary on the attack and its aftermath that he was witnessing live on television while I dutifully taught my writing class. “Hello, Patrick, where are you? Oh my god, another plane just hit the towers. Where are you?” The web was choked: no access to newspapers online. Email worked, but no one was wasting time writing. My office window looked out over a soccer field to the still woodlands of western New Jersey: behind me to the east the disaster must be unfolding. Finally I found a website with a live stream from ABC television, which I watched flickering and stilted on the tiny screen. It had all already happened: both towers already collapsed, the Pentagon attacked, another plane shot down over Pennsylvania, unconfirmed reports said, there were other hijacked aircraft still out there unaccounted for. Manhattan was sealed off. George Washington Bridge, Lincoln and Holland tunnels, all the bridges and tunnels from New Jersey I used to mock shut down. Police actions sealed off the highways into “the city.” The city I liked to think of as the capital of the world was cut off completely from the outside, suddenly vulnerable and under siege. There was no way to get home. The phone rang abruptly and Alex, three thousand miles away, told me he had spoken to Ana earlier and she was safe. After a dozen tries, I managed to get through and spoke to her, learning that she and Toby had seen people jumping and then the second tower fall. Other friends had been even closer. Everyone was safe, we thought. I sat for another couple of hours in my office uselessly. The news was incoherent, stories contradictory, loops of the planes hitting the towers only just ready for recycling. The attacks were already being transformed into “the World Trade Center Disaster,” not yet the ahistorical singularity of the emergency “nine one one.” Stranded, I had to spend the night in New Jersey at my boss’s house, reminded again of the boundless generosity of Americans to relative strangers. In an effort to protect his young son from the as yet unfiltered images saturating cable and Internet, my friend’s TV set was turned off and we did our best to reassure. We listened surreptitiously to news bulletins on AM radio, hoping that the roads would open. Walking the dog with my friend’s wife and son we crossed a park on the ridge on which Upper Montclair sits. Ten miles away a huge column of smoke was rising from lower Manhattan, where the stunning absence of the towers was clearly visible. The summer evening was unnervingly still. We kicked a soccer ball around on the front lawn and a woman walked distracted by, shocked and pale up the tree-lined suburban street, suffering her own wordless trauma. I remembered that though most of my students were ordinary working people, Montclair is a well-off dormitory for the financial sector and high rises of Wall Street and Midtown. For the time being, this was a white-collar disaster. I slept a short night in my friend’s house, waking to hope I had dreamed it all, and took the commuter train in with shell-shocked bankers and corporate types. All men, all looking nervously across the river toward glimpses of the Manhattan skyline as the train neared Hoboken. “I can’t believe they’re making us go in,” one guy had repeated on the station platform. He had watched the attacks from his office in Midtown, “The whole thing.” Inside the train we all sat in silence. Up from the PATH train station on 9th street I came onto a carless 6th Avenue. At 14th street barricades now sealed off downtown from the rest of the world. I walked down the middle of the avenue to a newspaper stand; the Indian proprietor shrugged “No deliveries below 14th.” I had not realized that the closer to the disaster you came, the less information would be available. Except, I assumed, for the evidence of my senses. But at 8 am the Village was eerily still, few people about, nothing in the sky, including the twin towers. I walked to Houston Street, which was full of trucks and police vehicles. Tractor trailers sat carrying concrete barriers. Below Houston, each street into Soho was barricaded and manned by huddles of cops. I had walked effortlessly up into the “lockdown,” but this was the “frozen zone.” There was no going further south towards the towers. I walked the few blocks home, found my wife sleeping, and climbed into bed, still in my clothes from the day before. “Your heart is racing,” she said. I realized that I hadn’t known if I would get back, and now I never wanted to leave again; it was still only eight thirty am. Lying there, I felt the terrible wonder of a distant bystander for the first-hand witness. Ana’s face couldn’t tell me what she had seen. I felt I needed to know more, to see and understand. Even though I knew the effort was useless: I could never bridge that gap that had trapped me ten miles away, my back turned to the unfolding disaster. The television was useless: we don’t have cable, and the mast on top of the North Tower, which Ana had watched fall, had relayed all the network channels. I knew I had to go down and see the wreckage. Later I would realize how lucky I had been not to suffer from “disaster envy.” Unbelievably, in retrospect, I commuted into work the second day after the attack, dogged by the same unnerving sensation that I would not get back—to the wounded, humbled former center of the world. My students were uneasy, all talked out. I was a novelty, a New Yorker living in the Village a mile from the towers, but I was forty-eight hours late. Out of place in both places. I felt torn up, but not angry. Back in the city at night, people were eating and drinking with a vengeance, the air filled with acrid sicklysweet smoke from the burning wreckage. Eyes stang and nose ran with a bitter acrid taste. Who knows what we’re breathing in, we joked nervously. A friend’s wife had fallen out with him for refusing to wear a protective mask in the house. He shrugged a wordlessly reassuring smile. What could any of us do? I walked with Ana down to the top of West Broadway from where the towers had commanded the skyline over SoHo; downtown dense smoke blocked the view to the disaster. A crowd of onlookers pushed up against the barricades all day, some weeping, others gawping. A tall guy was filming the grieving faces with a video camera, which was somehow the worst thing of all, the first sign of the disaster tourism that was already mushrooming downtown. Across the street an Asian artist sat painting the street scene in streaky black and white; he had scrubbed out two white columns where the towers would have been. “That’s the first thing I’ve seen that’s made me feel any better,” Ana said. We thanked him, but he shrugged blankly, still in shock I supposed. On the Friday, the clampdown. I watched the Mayor and Police Chief hold a press conference in which they angrily told the stream of volunteers to “ground zero” that they weren’t needed. “We can handle this ourselves. We thank you. But we don’t need your help,” Commissioner Kerik said. After the free-for-all of the first couple of days, with its amazing spontaneities and common gestures of goodwill, the clampdown was going into effect. I decided to go down to Canal Street and see if it was true that no one was welcome anymore. So many paths through the city were blocked now. “Lock down, frozen zone, war zone, the site, combat zone, ground zero, state troopers, secured perimeter, national guard, humvees, family center”: a disturbing new vocabulary that seemed to stamp the logic of Giuliani’s sanitized and over-policed Manhattan onto the wounded hulk of the city. The Mayor had been magnificent in the heat of the crisis; Churchillian, many were saying—and indeed, Giuliani quickly appeared on the cover of Cigar Afficionado, complete with wing collar and the misquotation from Kipling, “Captain Courageous.” Churchill had not believed in peacetime politics either, and he never got over losing his empire. Now the regime of command and control over New York’s citizens and its economy was being stabilized and reimposed. The sealed-off, disfigured, and newly militarized spaces of the New York through which I have always loved to wander at all hours seemed to have been put beyond reach for the duration. And, in the new post-“9/11” post-history, the duration could last forever. The violence of the attacks seemed to have elicited a heavy-handed official reaction that sought to contain and constrict the best qualities of New York. I felt more anger at the clampdown than I did at the demolition of the towers. I knew this was unreasonable, but I feared the reaction, the spread of the racial harassment and racial profiling that I had already heard of from my students in New Jersey. This militarizing of the urban landscape seemed to negate the sprawling, freewheeling, boundless largesse and tolerance on which New York had complacently claimed a monopoly. For many the towers stood for that as well, not just as the monumental outposts of global finance that had been attacked. Could the American flag mean something different? For a few days, perhaps—on the helmets of firemen and construction workers. But not for long. On the Saturday, I found an unmanned barricade way east along Canal Street and rode my bike past throngs of Chinatown residents, by the Federal jail block where prisoners from the first World Trade Center bombing were still being held. I headed south and west towards Tribeca; below the barricades in the frozen zone, you could roam freely, the cops and soldiers assuming you belonged there. I felt uneasy, doubting my own motives for being there, feeling the blood drain from my head in the same numbing shock I’d felt every time I headed downtown towards the site. I looped towards Greenwich Avenue, passing an abandoned bank full of emergency supplies and boxes of protective masks. Crushed cars still smeared with pulverized concrete and encrusted with paperwork strewn by the blast sat on the street near the disabled telephone exchange. On one side of the avenue stood a horde of onlookers, on the other television crews, all looking two blocks south towards a colossal pile of twisted and smoking steel, seven stories high. We were told to stay off the street by long-suffering national guardsmen and women with southern accents, kids. Nothing happening, just the aftermath. The TV crews were interviewing worn-out, dust-covered volunteers and firemen who sat quietly leaning against the railings of a park filled with scraps of paper. Out on the West Side highway, a high-tech truck was offering free cellular phone calls. The six lanes by the river were full of construction machinery and military vehicles. Ambulances rolled slowly uptown, bodies inside? I locked my bike redundantly to a lamppost and crossed under the hostile gaze of plainclothes police to another media encampment. On the path by the river, two camera crews were complaining bitterly in the heat. “After five days of this I’ve had enough.” They weren’t talking about the trauma, bodies, or the wreckage, but censorship. “Any blue light special gets to roll right down there, but they see your press pass and it’s get outta here. I’ve had enough.” I fronted out the surly cops and ducked under the tape onto the path, walking onto a Pier on which we’d spent many lazy afternoons watching the river at sunset. Dust everywhere, police boats docked and waiting, a crane ominously dredging mud into a barge. I walked back past the camera operators onto the highway and walked up to an interview in process. Perfectly composed, a fire chief and his crew from some small town in upstate New York were politely declining to give details about what they’d seen at “ground zero.” The men’s faces were dust streaked, their eyes slightly dazed with the shock of a horror previously unimaginable to most Americans. They were here to help the best they could, now they’d done as much as anyone could. “It’s time for us to go home.” The chief was eloquent, almost rehearsed in his precision. It was like a Magnum press photo. But he was refusing to cooperate with the media’s obsessive emotionalism. I walked down the highway, joining construction workers, volunteers, police, and firemen in their hundreds at Chambers Street. No one paid me any attention; it was absurd. I joined several other watchers on the stairs by Stuyvesant High School, which was now the headquarters for the recovery crews. Just two or three blocks away, the huge jagged teeth of the towers’ beautiful tracery lurched out onto the highway above huge mounds of debris. The TV images of the shattered scene made sense as I placed them into what was left of a familiar Sunday afternoon geography of bike rides and walks by the river, picnics in the park lying on the grass and gazing up at the infinite solidity of the towers. Demolished. It was breathtaking. If “they” could do that, they could do anything. Across the street at tables military policeman were checking credentials of the milling volunteers and issuing the pink and orange tags that gave access to ground zero. Without warning, there was a sudden stampede running full pelt up from the disaster site, men and women in fatigues, burly construction workers, firemen in bunker gear. I ran a few yards then stopped. Other people milled around idly, ignoring the panic, smoking and talking in low voices. It was a mainly white, blue-collar scene. All these men wearing flags and carrying crowbars and flashlights. In their company, the intolerance and rage I associated with flags and construction sites was nowhere to be seen. They were dealing with a torn and twisted otherness that dwarfed machismo or bigotry. I talked to a moustachioed, pony-tailed construction worker who’d hitched a ride from the mid-west to “come and help out.” He was staying at the Y, he said, it was kind of rough. “Have you been down there?” he asked, pointing towards the wreckage. “You’re British, you weren’t in World War Two were you?” I replied in the negative. “It’s worse ’n that. I went down last night and you can’t imagine it. You don’t want to see it if you don’t have to.” Did I know any welcoming ladies? he asked. The Y was kind of tough. When I saw TV images of President Bush speaking to the recovery crews and steelworkers at “ground zero” a couple of days later, shouting through a bullhorn to chants of “USA, USA” I knew nothing had changed. New York’s suffering was subject to a second hijacking by the brokers of national unity. New York had never been America, and now its terrible human loss and its great humanity were redesignated in the name of the nation, of the coming war. The signs without a referent were being forcibly appropriated, locked into an impoverished patriotic framework, interpreted for “us” by a compliant media and an opportunistic regime eager to reign in civil liberties, to unloose its war machine and tighten its grip on the Muslim world. That day, drawn to the river again, I had watched F18 fighter jets flying patterns over Manhattan as Bush’s helicopters came in across the river. Otherwise empty of air traffic, “our” skies were being torn up by the military jets: it was somehow the worst sight yet, worse than the wreckage or the bands of disaster tourists on Canal Street, a sign of further violence yet to come. There was a carrier out there beyond New York harbor, there to protect us: the bruising, blustering city once open to all comers. That felt worst of all. In the intervening weeks, we have seen other, more unstable ways of interpreting the signs of September 11 and its aftermath. Many have circulated on the Internet, past the blockages and blockades placed on urban spaces and intellectual life. Karl-Heinz Stockhausen’s work was banished (at least temporarily) from the canon of avant-garde electronic music when he described the attack on las torres gemelas as akin to a work of art. If Jacques Derrida had described it as an act of deconstruction (turning technological modernity literally in on itself), or Jean Baudrillard had announced that the event was so thick with mediation it had not truly taken place, something similar would have happened to them (and still may). This is because, as Don DeLillo so eloquently put it in implicit reaction to the plaintive cry “Why do they hate us?”: “it is the power of American culture to penetrate every wall, home, life and mind”—whether via military action or cultural iconography. All these positions are correct, however grisly and annoying they may be. What GK Chesterton called the “flints and tiles” of nineteenth-century European urban existence were rent asunder like so many victims of high-altitude US bombing raids. As a First-World disaster, it became knowable as the first-ever US “ground zero” such precisely through the high premium immediately set on the lives of Manhattan residents and the rarefied discussion of how to commemorate the high-altitude towers. When, a few weeks later, an American Airlines plane crashed on take-off from Queens, that borough was left open to all comers. Manhattan was locked down, flown over by “friendly” bombers. In stark contrast to the open if desperate faces on the street of 11 September, people went about their business with heads bowed even lower than is customary. Contradictory deconstructions and valuations of Manhattan lives mean that September 11 will live in infamy and hyper-knowability. The vengeful United States government and population continue on their way. Local residents must ponder insurance claims, real-estate values, children’s terrors, and their own roles in something beyond their ken. New York had been forced beyond being the center of the financial world. It had become a military target, a place that was receiving as well as dispatching the slings and arrows of global fortune.

From elephants to ABBA fans, silicon to hormone, the following discussion uses a new research method to look at printed text, motion pictures and a teenage rebel icon. If by ‘print’ we mean a mechanically reproduced impression of a cultural symbol in a medium, then printing has been with us since before microdot security prints were painted onto cars, before voice prints, laser prints, network servers, record pressings, motion picture prints, photo prints, colour woodblock prints, before books, textile prints, and footprints. If we accept that higher mammals such as elephants have a learnt culture, then it is possible to extend a definition of printing beyond Homo sapiens. Poole reports that elephants mechanically trumpet reproductions of human car horns into the air surrounding their society. If nothing else, this cross-species, cross-cultural reproduction, this ‘ability to mimic’ is ‘another sign of their intelligence’. Observation of child development suggests that the first significant meaningful ‘impression’ made on the human mind is that of the face of the child’s nurturer – usually its mother. The baby’s mind forms an ‘impression’, a mental print, a reproducible memory data set, of the nurturer’s face, voice, smell, touch, etc. That face is itself a cultural construct: hair style, makeup, piercings, tattoos, ornaments, nutrition-influenced skin and smell, perfume, temperature and voice. A mentally reproducible pattern of a unique face is formed in the mind, and we use that pattern to distinguish ‘familiar and strange’ in our expanding social orbit. The social relations of patterned memory – of imprinting – determine the extent to which we explore our world (armed with research aids such as text print) or whether we turn to violence or self-harm (Bretherton). While our cultural artifacts (such as vellum maps or networked voice message servers) bravely extend our significant patterns into the social world and the traversed environment, it is useful to remember that such artifacts, including print, are themselves understood by our original pattern-reproduction and impression system – the human mind, developed in childhood. The ‘print’ is brought to mind differently in different discourses. For a reader, a ‘print’ is a book, a memo or a broadsheet, whether it is the Indian Buddhist Sanskrit texts ordered to be printed in 593 AD by the Chinese emperor Sui Wen-ti (Silk Road) or the US Defense Department memo authorizing lower ranks to torture the prisoners taken by the Bush administration (Sanchez, cited in ABC). Other fields see prints differently. For a musician, a ‘print’ may be the sheet music which spread classical and popular music around the world; it may be a ‘record’ (as in a ‘recording’ session), where sound is impressed to wax, vinyl, charged silicon particles, or the alloys (Smith, “Elpida”) of an mp3 file. For the fine artist, a ‘print’ may be any mechanically reproduced two-dimensional (or embossed) impression of a significant image in media from paper to metal, textile to ceramics. ‘Print’ embraces the Japanese Ukiyo-e colour prints of Utamaro, the company logos that wink from credit card holographs, the early photographs of Talbot, and the textured patterns printed into neolithic ceramics. Computer hardware engineers print computational circuits. Homicide detectives investigate both sweaty finger prints and the repeated, mechanical gaits of suspects, which are imprinted into the earthy medium of a crime scene. For film makers, the ‘print’ may refer to a photochemical polyester reproduction of a motion picture artifact (the reel of ‘celluloid’), or a DVD laser disc impression of the same film. Textualist discourse has borrowed the word ‘print’ to mean ‘text’, so ‘print’ may also refer to the text elements within the vision track of a motion picture: the film’s opening titles, or texts photographed inside the motion picture story such as the sword-cut ‘Z’ in Zorro (Niblo). Before the invention of writing, the main mechanically reproduced impression of a cultural symbol in a medium was the humble footprint in the sand. The footprints of tribes – and neighbouring animals – cut tracks in the vegetation and the soil. Printed tracks led towards food, water, shelter, enemies and friends. Having learnt to pattern certain faces into their mental world, children grew older and were educated in the footprints of family and clan, enemies and food. The continuous impression of significant foot traffic in the medium of the earth produced the lines between significant nodes of prewriting and pre-wheeled cultures. These tracks were married to audio tracks, such as the song lines of the Australian Aborigines, or the ballads of tramping culture everywhere. A typical tramping song has the line, ‘There’s a track winding back to an old-fashion shack along the road to Gundagai,’ (O’Hagan), although this colonial-style song was actually written for radio and became an international hit on the airwaves, rather than the tramping trails. The printed tracks impressed by these cultural flows are highly contested and diverse, and their foot prints are woven into our very language. The names for printed tracks have entered our shared memory from the intersection of many cultures: ‘Track’ is a Germanic word entering English usage comparatively late (1470) and now used mainly in audio visual cultural reproduction, as in ‘soundtrack’. ‘Trek’ is a Dutch word for ‘track’ now used mainly by ecotourists and science fiction fans. ‘Learn’ is a Proto-Indo-European word: the verb ‘learn’ originally meant ‘to find a track’ back in the days when ‘learn’ had a noun form which meant ‘the sole of the foot’. ‘Tract’ and ‘trace’ are Latin words entering English print usage before 1374 and now used mainly in religious, and electronic surveillance, cultural reproduction. ‘Trench’ in 1386 was a French path cut through a forest. ‘Sagacity’ in English print in 1548 was originally the ability to track or hunt, in Proto-Indo-European cultures. ‘Career’ (in English before 1534) was the print made by chariots in ancient Rome. ‘Sleuth’ (1200) was a Norse noun for a track. ‘Investigation’ (1436) was Latin for studying a footprint (Harper). The arrival of symbolic writing scratched on caves, hearth stones, and trees (the original meaning of ‘book’ is tree), brought extremely limited text education close to home. Then, with baked clay tablets, incised boards, slate, bamboo, tortoise shell, cast metal, bark cloth, textiles, vellum, and – later – paper, a portability came to text that allowed any culture to venture away from known ‘foot’ paths with a reduction in the risk of becoming lost and perishing. So began the world of maps, memos, bills of sale, philosophic treatises and epic mythologies. Some of this was printed, such as the mechanical reproduction of coins, but the fine handwriting required of long, extended, portable texts could not be printed until the invention of paper in China about 2000 years ago. Compared to lithic architecture and genes, portable text is a fragile medium, and little survives from the millennia of its innovators. The printing of large non-text designs onto bark-paper and textiles began in neolithic times, but Sui Wen-ti’s imperial memo of 593 AD gives us the earliest written date for printed books, although we can assume they had been published for many years previously. The printed book was a combination of Indian philosophic thought, wood carving, ink chemistry and Chinese paper. The earliest surviving fragment of paper-print technology is ‘Mantras of the Dharani Sutra’, a Buddhist scripture written in the Sanskrit language of the Indian subcontinent, unearthed at an early Tang Dynasty site in Xian, China – making the fragment a veteran piece of printing, in the sense that Sanskrit books had been in print for at least a century by the early Tang Dynasty (Chinese Graphic Arts Net). At first, paper books were printed with page-size carved wooden boards. Five hundred years later, Pi Sheng (c.1041) baked individual reusable ceramic characters in a fire and invented the durable moveable type of modern printing (Silk Road 2000). Abandoning carved wooden tablets, the ‘digitizing’ of Chinese moveable type sped up the production of printed texts. In turn, Pi Sheng’s flexible, rapid, sustainable printing process expanded the political-cultural impact of the literati in Asian society. Digitized block text on paper produced a bureaucratic, literate elite so powerful in Asia that Louis XVI of France copied China’s print-based Confucian system of political authority for his own empire, and so began the rise of the examined public university systems, and the civil service systems, of most European states (Watson, Visions). By reason of its durability, its rapid mechanical reproduction, its culturally agreed signs, literate readership, revered authorship, shared ideology, and distributed portability, a ‘print’ can be a powerful cultural network which builds and expands empires. But print also attacks and destroys empires. A case in point is the Spanish conquest of Aztec America: The Aztecs had immense libraries of American literature on bark-cloth scrolls, a technology which predated paper. These libraries were wiped out by the invading Spanish, who carried a different book before them (Ewins). In the industrial age, the printing press and the gun were seen as the weapons of rebellions everywhere. In 1776, American rebels staffed their ‘Homeland Security’ units with paper makers, knowing that defeating the English would be based on printed and written documents (Hahn). Mao Zedong was a book librarian; Mao said political power came out of the barrel of a gun, but Mao himself came out of a library. With the spread of wireless networked servers, political ferment comes out of the barrel of the cell phone and the internet chat room these days. Witness the cell phone displays of a plane hitting a tower that appear immediately after 9/11 in the Middle East, or witness the show trials of a few US and UK lower ranks who published prints of their torturing activities onto the internet: only lower ranks who published prints were arrested or tried. The control of secure servers and satellites is the new press. These days, we live in a global library of burning books – ‘burning’ in the sense that ‘print’ is now a charged silicon medium (Smith, “Intel”) which is usually made readable by connecting the chip to nuclear reactors and petrochemically-fired power stations. World resources burn as we read our screens. Men, women, children burn too, as we watch our infotainment news in comfort while ‘their’ flickering dead faces are printed in our broadcast hearths. The print we watch is not the living; it is the voodoo of the living in the blackout behind the camera, engaging the blood sacrifice of the tormented and the unfortunate. Internet texts are also ‘on fire’ in the third sense of their fragility and instability as a medium: data bases regularly ‘print’ fail-safe copies in an attempt to postpone the inevitable mechanical, chemical and electrical failure that awaits all electronic media in time. Print defines a moral position for everyone. In reporting conflict, in deciding to go to press or censor, any ‘print’ cannot avoid an ethical context, starting with the fact that there is a difference in power between print maker, armed perpetrators, the weak, the peaceful, the publisher, and the viewer. So many human factors attend a text, video or voice ‘print’: its very existence as an aesthetic object, even before publication and reception, speaks of unbalanced, and therefore dynamic, power relationships. For example, Graham Greene departed unscathed from all the highly dangerous battlefields he entered as a novelist: Riot-torn Germany, London Blitz, Belgian Congo, Voodoo Haiti, Vietnam, Panama, Reagan’s Washington, and mafia Europe. His texts are peopled with the injustices of the less fortunate of the twentieth century, while he himself was a member of the fortunate (if not happy) elite, as is anyone today who has the luxury of time to read Greene’s works for pleasure. Ethically a member of London and Paris’ colonizers, Greene’s best writing still electrifies, perhaps partly because he was in the same line of fire as the victims he shared bread with. In fact, Greene hoped daily that he would escape from the dreadful conflicts he fictionalized via a body bag or an urn of ashes (see Sherry). In reading an author’s biography we have one window on the ethical dimensions of authority and print. If a print’s aesthetics are sometimes enduring, its ethical relationships are always mutable. Take the stylized logo of a running athlete: four limbs bent in a rotation of action. This dynamic icon has symbolized ‘good health’ in Hindu and Buddhist culture, from Madras to Tokyo, for thousands of years. The cross of bent limbs was borrowed for the militarized health programs of 1930s Germany, and, because of what was only a brief, recent, isolated yet monstrously horrific segment of its history in print, the bent-limbed swastika is now a vilified symbol in the West. The sign remains ‘impressed’ differently on traditional Eastern culture, and without the taint of Nazism. Dramatic prints are emotionally charged because, in depicting Homo sapiens in danger, or passionately in love, they elicit a hormonal reaction from the reader, the viewer, or the audience. The type of emotions triggered by a print vary across the whole gamut of human chemistry. A recent study of three genres of motion picture prints shows a marked differences in the hormonal responses of men compared to women when viewing a romance, an actioner, and a documentary (see Schultheiss, Wirth, and Stanton). Society is biochemically diverse in its engagement with printed culture, which raises questions about equality in the arts. Motion picture prints probably comprise around one third of internet traffic, in the form of stolen digitized movie files pirated across the globe via peer-to-peer file transfer networks (p2p), and burnt as DVD laser prints (BBC). There is also a US 40 billion dollar per annum legitimate commerce in DVD laser pressings (Grassl), which would suggest an US 80 billion per annum world total in legitimate laser disc print culture. The actively screen literate, or the ‘sliterati’ as I prefer to call them, research this world of motion picture prints via their peers, their internet information channels, their television programming, and their web forums. Most of this activity occurs outside the ambit of universities and schools. One large site of sliterate (screen literate) practice outside most schooling and official research is the net of online forums at imdb.com (International Movie Data Base). Imdb.com ‘prints’ about 25,000,000 top pages per month to client browsers. Hundreds of sliterati forums are located at imdb, including a forum for the Australian movie, Muriel’s Wedding (Hogan). Ten years after the release of Muriel’s Wedding, young people who are concerned with victimization and bullying still log on to http://us.imdb.com/title/tt0110598/board/> and put their thoughts into print: I still feel so bad for Muriel in the beginning of the movie, when the girls ‘dump’ her, and how much the poor girl cried and cried! Those girls were such biartches…I love how they got their comeuppance! bunniesormaybemidgets’s comment is typical of the current discussion. Muriel’s Wedding was a very popular film in its first cinema edition in Australia and elsewhere. About 30% of the entire over-14 Australian population went to see this photochemical polyester print in the cinemas on its first release. A decade on, the distributors printed a DVD laser disc edition. The story concerns Muriel (played by Toni Collette), the unemployed daughter of a corrupt, ‘police state’ politician. Muriel is bullied by her peers and she withdraws into a fantasy world, deluding herself that a white wedding will rescue her from the torments of her blighted life. Through theft and deceit (the modus operandi of her father) Muriel escapes to the entertainment industry and finds a ‘wicked’ girlfriend mentor. From a rebellious position of stubborn independence, Muriel plays out her fantasy. She gets her white wedding, before seeing both her father and her new married life as hollow shams which have goaded her abandoned mother to suicide. Redefining her life as a ‘game’ and assuming responsibility for her independence, Muriel turns her back on the mainstream, image-conscious, female gang of her oppressed youth. Muriel leaves the story, having rekindled her friendship with her rebel mentor. My methodological approach to viewing the laser disc print was to first make a more accessible, coded record of the entire movie. I was able to code and record the print in real time, using a new metalanguage (Watson, “Eyes”). The advantage of Coding is that ‘thinks’ the same way as film making, it does not sidetrack the analyst into prose. The Code splits the movie print into Vision Action [vision graphic elements, including text] (sound) The Coding splits the vision track into normal action and graphic elements, such as text, so this Coding is an ideal method for extracting all the text elements of a film in real time. After playing the film once, I had four and a half tightly packed pages of the coded story, including all its text elements in square brackets. Being a unique, indexed hard copy, the Coded copy allowed me immediate access to any point of the Muriel’s Wedding saga without having to search the DVD laser print. How are ‘print’ elements used in Muriel’s Wedding? Firstly, a rose-coloured monoprint of Muriel Heslop’s smiling face stares enigmatically from the plastic surface of the DVD picture disc. The print is a still photo captured from her smile as she walked down the aisle of her white wedding. In this print, Toni Collette is the Mona Lisa of Australian culture, except that fans of Muriel’s Wedding know the meaning of that smile is a magical combination of the actor’s art: the smile is both the flush of dreams come true and the frightening self deception that will kill her mother. Inserting and playing the disc, the text-dominant menu appears, and the film commences with the text-dominant opening titles. Text and titles confer a legitimacy on a work, whether it is a trade mark of the laser print owners, or the household names of stars. Text titles confer status relationships on both the presenters of the cultural artifact and the viewer who has entered into a legal license agreement with the owners of the movie. A title makes us comfortable, because the mind always seeks to name the unfamiliar, and a set of text titles does that job for us so that we can navigate the ‘tracks’ and settle into our engagement with the unfamiliar. The apparent ‘truth’ and ‘stability’ of printed text calms our fears and beguiles our uncertainties. Muriel attends the white wedding of a school bully bride, wearing a leopard print dress she has stolen. Muriel’s spotted wild animal print contrasts with the pure white handmade dress of the bride. In Muriel’s leopard textile print, we have the wild, rebellious, impoverished, inappropriate intrusion into the social ritual and fantasy of her high-status tormentor. An off-duty store detective recognizes the printed dress and calls the police. The police are themselves distinguished by their blue-and-white checked prints and other mechanically reproduced impressions of cultural symbols: in steel, brass, embroidery, leather and plastics. Muriel is driven in the police car past the stenciled town sign (‘Welcome To Porpoise Spit’ heads a paragraph of small print). She is delivered to her father, a politician who presides over the policing of his town. In a state where the judiciary, police and executive are hijacked by the same tyrant, Muriel’s father, Bill, pays off the police constables with a carton of legal drugs (beer) and Muriel must face her father’s wrath, which he proceeds to transfer to his detested wife. Like his daughter, the father also wears a spotted brown print costume, but his is a batik print from neighbouring Indonesia (incidentally, in a nation that takes the political status of its batik prints very seriously). Bill demands that Muriel find the receipt for the leopard print dress she claims she has purchased. The legitimate ownership of the object is enmeshed with a printed receipt, the printed evidence of trade. The law (and the paramilitary power behind the law) are legitimized, or contested, by the presence or absence of printed text. Muriel hides in her bedroom, surround by poster prints of the pop group ABBA. Torn-out prints of other people’s weddings adorn her mirror. Her face is embossed with the clown-like primary colours of the marionette as she lifts a bouquet to her chin and stares into the real time ‘print’ of her mirror image. Bill takes the opportunity of a business meeting with Japanese investors to feed his entire family at ‘Charlie Chan’’s restaurant. Muriel’s middle sister sloppily wears her father’s state election tee shirt, printed with the text: ‘Vote 1, Bill Heslop. You can’t stop progress.’ The text sets up two ironic gags that are paid off on the dialogue track: “He lost,’ we are told. ‘Progress’ turns out to be funding the concreting of a beach. Bill berates his daughter Muriel: she has no chance of becoming a printer’s apprentice and she has failed a typing course. Her dysfunction in printed text has been covered up by Bill: he has bribed the typing teacher to issue a printed diploma to his daughter. In the gambling saloon of the club, under the arrays of mechanically repeated cultural symbols lit above the poker machines (‘A’ for ace, ‘Q’ for queen, etc.), Bill’s secret girlfriend Diedre risks giving Muriel a cosmetics job. Another text icon in lights announces the surf nightclub ‘Breakers’. Tania, the newly married queen bitch who has made Muriel’s teenage years a living hell, breaks up with her husband, deciding to cash in his negotiable text documents – his Bali honeymoon tickets – and go on an island holiday with her girlfriends instead. Text documents are the enduring site of agreements between people and also the site of mutations to those agreements. Tania dumps Muriel, who sobs and sobs. Sobs are a mechanical, percussive reproduction impressed on the sound track. Returning home, we discover that Muriel’s older brother has failed a printed test and been rejected for police recruitment. There is a high incidence of print illiteracy in the Heslop family. Mrs Heslop (Jeannie Drynan), for instance, regularly has trouble at the post office. Muriel sees a chance to escape the oppression of her family by tricking her mother into giving her a blank cheque. Here is the confluence of the legitimacy of a bank’s printed negotiable document with the risk and freedom of a blank space for rebel Muriel’s handwriting. Unable to type, her handwriting has the power to steal every cent of her father’s savings. She leaves home and spends the family’s savings at an island resort. On the island, the text print-challenged Muriel dances to a recording (sound print) of ABBA, her hand gestures emphasizing her bewigged face, which is made up in an impression of her pop idol. Her imitation of her goddesses – the ABBA women, her only hope in a real world of people who hate or avoid her – is accompanied by her goddesses’ voices singing: ‘the mystery book on the shelf is always repeating itself.’ Before jpeg and gif image downloads, we had postcard prints and snail mail. Muriel sends a postcard to her family, lying about her ‘success’ in the cosmetics business. The printed missal is clutched by her father Bill (Bill Hunter), who proclaims about his daughter, ‘you can’t type but you really impress me’. Meanwhile, on Hibiscus Island, Muriel lies under a moonlit palm tree with her newly found mentor, ‘bad girl’ Ronda (Rachel Griffiths). In this critical scene, where foolish Muriel opens her heart’s yearnings to a confidante she can finally trust, the director and DP have chosen to shoot a flat, high contrast blue filtered image. The visual result is very much like the semiabstract Japanese Ukiyo-e woodblock prints by Utamaro. This Japanese printing style informed the rise of European modern painting (Monet, Van Gogh, Picasso, etc., were all important collectors and students of Ukiyo-e prints). The above print and text elements in Muriel’s Wedding take us 27 minutes into her story, as recorded on a single page of real-time handwritten Coding. Although not discussed here, the Coding recorded the complete film – a total of 106 minutes of text elements and main graphic elements – as four pages of Code. Referring to this Coding some weeks after it was made, I looked up the final code on page four: taxi [food of the sea] bq. Translation: a shop sign whizzes past in the film’s background, as Muriel and Ronda leave Porpoise Spit in a taxi. Over their heads the text ‘Food Of The Sea’ flashes. We are reminded that Muriel and Ronda are mermaids, fantastic creatures sprung from the brow of author PJ Hogan, and illuminated even today in the pantheon of women’s coming-of-age art works. That the movie is relevant ten years on is evidenced by the current usage of the Muriel’s Wedding online forum, an intersection of wider discussions by sliterate women on imdb.com who, like Muriel, are observers (and in some cases victims) of horrific pressure from ambitious female gangs and bullies. Text is always a minor element in a motion picture (unless it is a subtitled foreign film) and text usually whizzes by subliminally while viewing a film. By Coding the work for [text], all the text nuances made by the film makers come to light. While I have viewed Muriel’s Wedding on many occasions, it has only been in Coding it specifically for text that I have noticed that Muriel is a representative of that vast class of talented youth who are discriminated against by print (as in text) educators who cannot offer her a life-affirming identity in the English classroom. Severely depressed at school, and failing to type or get a printer’s apprenticeship, Muriel finds paid work (and hence, freedom, life, identity, independence) working in her audio visual printed medium of choice: a video store in a new city. Muriel found a sliterate admirer at the video store but she later dumped him for her fantasy man, before leaving him too. One of the points of conjecture on the imdb Muriel’s Wedding site is, did Muriel (in the unwritten future) get back together with admirer Brice Nobes? That we will never know. While a print forms a track that tells us where culture has been, a print cannot be the future, a print is never animate reality. At the end of any trail of prints, one must lift one’s head from the last impression, and negotiate satisfaction in the happening world.

Occuring frictional induced vibration of dry clutches and brakes can lead to NVH (Noise Vibration Harshness) and functional disorder of clutches in machines and automobiles. This behaviour is not accepted by the costomer. In consequence the system components are often overdimensioned, which is not acceptable in reasons of economy and a decreasing mounting space. To solve these problems a model based method has been developed, which allows a sophisticated dimensioning of clutch systems in view of the occurrence of frictional vibration and transmittable torque.

Abstract The main potential advantage of electro-rheological fluid when used as the interface medium between electronics and actuators in high speed machines is its ability to respond quickly to a change in the control signal. The analysis reported in this paper shows that over the operating speed range the system has a time constant of less than one millisecond and for most practical applications it can be assumed that when a suitable control strategy is employed the output torque would be proportional to the control signal. Most electro-mechanical torque transducers have time constant of over 10 milliseconds and therefore direct measurement of the torque produced by the electro-rheological clutch would be very expensive if not impractical. This paper reports a numerical method of identifying the torque response from the output of a conventional torque transducer which has a natural frequency of 110 Hz. The transfer function is first identified from a standard step input test, and the torque response of the clutch then is estimated from the measured signal. Although the noise on the signal will be always amplified with this method the use of a digital filter makes it possible to obtain an accurate estimate of the torque response.
