The next stop on the visit was Rosehill School, an outstanding LA-maintained special school in the East Midlands. Damian Hinds met members of the student council to hear about some of their creative projects and then listened to parents’ views on their children’s school experience.The Secretary of State added: It’s a mark of a strong society how we treat children who are most in need of our support. Every child, no matter what challenges they face, should have access to a world-class education that prepares them for life in the modern world. I’ve really been inspired by my visit to Rosehill School and the way the teachers work with the children to provide an excellent education with the deepest understanding of their additional needs. The happiness of the parents I met was a real testament to the quality of the education the hard-working teachers and staff provide. Education Secretary Damian Hinds heard first hand from pupils, teachers, apprentices and parents about the high quality education they were receiving during a visit to Nottingham (23 March).The Secretary of State spent the morning meeting apprentices at Uniper Engineering Academy based at Ratcliffe Power Station, before CEO David Hughes provided a tour of the academy to observe lessons. Students explained why they chose an apprenticeship and what their ambitions for the future were. This was followed by a discussion with local Apprenticeship Ambassadors and businesses about how the Government can encourage more people to take up apprenticeships.Education Secretary Damian Hinds said: The high quality training I witnessed at Uniper today showed what quality apprenticeships can deliver. I want more people to choose the apprenticeship route and am determined that every apprentice, whatever their age, background or aspiration, has access to great training that will set them up for a successful career.
Former USC tailback Stafon Johnson filed a lawsuit against USC in Los Angeles County Superior Court on Monday.Johnson claimed negligence on behalf of former assistant strength coach Jamie Yanchar and the school related to a severe throat injury he sustained during a weightlifting accident in September 2009.The other story · Johnson’s lawsuit alleges that a former USC assistant strength and conditiong coach is responsible for the severe throat injury he sustained during a mandatory team workout in September 2009. – Daily Trojan file photo Along with his mother, Kim Mallory, and attorney Carl Douglas, Johnson held a news conference Monday afternoon in Beverly Hills announcing the filing of a personal injury lawsuit against Yanchar and the university. During the gathering, he read from a prepared statement, while Douglas and Mallory answered questions from the media.Seeking unspecified damages for medical-related expenses, pain and suffering and loss of potential earnings in excess of $25,000, the lawsuit alleges that Yanchar was not paying attention to Johnson at the time of the accident.“Defendant Yanchar’s negligent, careless and reckless act and omission, in striking the bar with his body, was something that Mr. Johnson was not expecting to occur and he was therefore unprepared for the bar to be knocked off balance,” read the lawsuit.In the aftermath, Johnson was forced to undergo several surgeries and therapy for injuries stemming from the incident.On Sept. 28, 2009, Johnson dropped a barrel carrying 275 pounds of weight on himself while bench pressing in USC’s weight room during a mandatory team weight lifting session, causing serious injuries to his throat, and causing him to be hospitalized for approximately three weeks. He missed the remainder of the season.The lawsuit, however, insists that Johnson did not drop the bar on his throat, as reports initially indicated.“What we say occurred is that the bar was basically knocked out of his hand, causing it to fall on Stafon’s neck, almost causing him to die,” Douglas told reporters during Monday’s news conference. “We think for that, those that are responsible should be held responsible for their actions.”Yanchar spent the last season with the NFL’s Seattle Seahawks, working for former USC coach Pete Carroll in a similar capacity. Two weeks after Carroll departed for the Seahawks, Yanchar was hired, leaving his position as interim strength coach.“USC firmly believes it was not at fault in Stafon Johnson’s unfortunate weightlifting accident,” USC said in a statement released Monday afternoon. “We are sorry that Stafon was injured. USC and the entire Trojan Family have been exceptionally supportive of Stafon from the minute the accident occurred. We are disappointed to learn that Stafon has decided to file a lawsuit against USC.”To read more about the lawsuit, click here.

Chelsea have made an initial approach to try to lure Pep Guardiola away from Barcelona, according to the Daily Mirror.The Nou Camp boss, whose contract expires in the summer, is one of the favourites to take over at Stamford Bridge.It is claimed that tentative feelers have already been put out by intermediaries seeking to put a deal together which could see Guardiola quit the European champions to be Chelsea’s eighth manager since 2004.The Mirror also suggest Andre Villas-Boas left in tears after being sacked by the Blues – despite getting a £10m pay-off – and was also said to be upset that the majority of the squad did not say goodbye or wish him luck.The Sun declare that former Liverpool boss Rafael Benitez has invited Chelsea to make him an offer.Meanwhile, the Daily Mail report that Hamburg sporting director Frank Arnesen is hoping that Chelsea will let him sign Romelu Lukaku on loan this summer.Arnesen, formerly director of football at the Bridge, is understood to want to take the 18-year-old to the Bundesliga on a season-long deal.Follow West London Sport on TwitterFind us on Facebook
Flowering plants burst on the scene in the fossil record 140 million years ago in the geologic timescale, creating an “abominable mystery” for Charles Darwin. What can be learned by measuring the stems and leaves of fossil specimens? Dana Royer and colleagues from Wesleyan University in Connecticut embarked on a project to measure ratios of petiole width and leaf area from 179 species of angiosperms (flowering plants) from three areas of the Albian period, cited 100-110 million years old. The majority of the fossils had a low leaf mass per area. They compared these ratios with the growth habits of living gymnosperms and angiosperms. Assuming that today’s growth patterns held in the past, they inferred that the fossil angiosperms were short-lived, fast-growing species – like weeds. What does this mean? Science Daily quoted Dr. Royer: “While this doesn’t tell us anything directly about the earliest angiosperms – the oldest angiosperm pollen is around 140 Ma old – the Albian marks the time when angiosperms begin to be very diverse and important ecologically,” he said. “It is likely that explosive growth is one reason for the success of angiosperms.”The number of assumptions in the method and its presuppositions outweigh any validity of the conclusions. First, the dating of the fossils is imbued with evolutionary assumptions. Second, the statement “the Albian marks the time when angiosperms begin to be very diverse and important ecologically” is miracle talk. It is distraction for “We have no idea what happened.” Basically, complex plants “emerged” and ”exploded” onto the scene, like universes, Cambrian animals and everything else does in Darwinian theory. Suppose – just suppose – for the sake of argument, just allow the remote possibility – that plants were created. Then no amount of measuring petioles and leaf area is going to tell you how they evolved. You can measure them with a micrometer, and have them listed in spreadsheets to four significant figures. You can produce the most dazzling Powerpoint presentations. You can even establish a relationship between the ratios and growth habits of living plants (as they did). Even if you believe plants evolved, none of this busy work provides one iota of evidence for evolution. Strip away the assumption of evolution, and restrict yourself to empiricism. All you have done is describe certain mathematical relationships between living species, with a possible inference that those relationships held in the past among extinct species. If that’s all Dr. Royer was trying to do, fine; he said, “While this doesn’t tell us anything directly about the earliest angiosperms… the Albian marks the time when angiosperms begin to be very diverse and important ecologically.” That could be the third day of creation, presumably. Has he proven otherwise by anything he has done? There seems to be an evolutionary undertone in the article, but where is the evidence for millions of years of slow, gradual change by mutation and selection, followed by explosive diversification of complex, wholly new forms of plants? “It is likely that explosive growth is one reason for the success of angiosperms,” he concluded. Amen, hallelujah. That’s what they were designed to do: succeed. And your point is? Don’t couch miracle talk in hidden variables. Tell us Darwinly how “explosive growth” evolved: here, at the Cambrian explosion, and at the birth of a universe out of absolutely nothing. Until then, don’t call it science; call it leaf collecting.(Visited 6 times, 1 visits today)FacebookTwitterPinterestSave分享0

Nothing ruins a shot like noise. Knowing what causes it and how to recognize it can save you a lot of frustration — and some useless footage.There are few things as frustrating as noticing noise in an image while you’re shooting but being unable to identify the cause of the problem. In this article, we will take an in-depth look at noise by first reviewing some basic sensor science before examining noise in its various forms. So where to start?Imaging.Imaging BasicsNoise comes from a couple of sources. Reflected light streams into the lens and falls on the sensor, which is covered in millions of photosites — or pixels — that convert the variable levels of the light waves into digital signals. These small variances in current are what create images in modern sensors.In the most common sensor for film production these days, the CMOS, attached to each photosite is an amplifier that adjusts the output of each pixel by cutting or boosting voltage, making the image darker or brighter, respectively. The user can do this by adjusting the gain or ISO. The data from the sensor gets read and the pixel charge resets.Once the sensor information gets read, the data passes through a 12-bit analog-to-digital converter (frequently shortened to ADC or A/D) where the variance in voltage to each pixel gets converted to a binary value. Additionally, pixel location and other user-defined camera settings get saved as metadata in the camera storage device.The majority of noise comes from the sensor or analog-to-digital conversion.What Is Image Noise?Put simply, image noise is undesired fluctuations of color or luminance that obscure detail in the shot you were trying to capture. (You can see examples of various kinds of noise over at Neat Video.)Image noise arises primarily in underexposed footage as pixels have little light fluctuation to report in the intended image but are being over-amplified by boosted ISO values. Beyond exposure, sensors are also susceptible to a range of other issues that create noise in the final image. The heat of the sensor or other outside interference can also cause noise.We can divide image noise into two categories: internal and interference.Internal NoiseImage via Neat Video.Image noise originating from within the camera has a few root causes. The three main causes are electricity, heat, and sensor illumination levels.In low-light situations where the sensor is being over-volted (ISO being pushed), each pixel has very little light wave fluctuation to report before being amplified. When you see noise in these situations, you are actually seeing the affected pixels reporting the fluctuations of the voltage of the pixel’s amplifier over the sensor.Interference NoiseImage via Neat Video.Factors beyond the camera may also affect noise levels in the final image. This kind of noise is a bit rarer than internal noise in many modern cameras, but it can still affect the final image.Interference noise is typically fairly easy to spot because it looks more like a pattern overlay on your image rather than the fluttering inherent to electronic noise. Mundane factors like strong radio transmissions in the area can also cause electronic noise — and they’re as hard to control as cosmic radiation.What Are the Most Common Types of Video Noise?InternalGaussian NoiseImage via NeatVideo.Gaussian noise is a type of sensor noise. It’s primarily a side-effect of sensor heat. The heat is usually a result of voltage and illumination levels of the sensor.Gaussian noise is most noticeable as a constant, fluttering across an underexposed, over-volted (ISO pushed to get exposure) frame. In most sensors, this noise will tend to be blue in underexposed images.Fixed-Pattern NoiseFixed-pattern noise usually results from flaws in the manufacturing process of a particular sensor. It arises when different pixels have different levels of photosensitivity.In video, this noise is relatively easy to spot due to the small variance in the output levels of affected pixels. FPN doesn’t move or chatter in the way other forms of electronic noise do. Instead, it appears as an overlay of pixels brighter than the actual information being recorded. It is easiest to spot in low-light situations, but other factors can exacerbate it as well.Salt and Pepper NoiseImage via NeatVideo.Technically referred to as either “Fat-tail distributed” or “Impulsive” noise, Salt and Pepper noise manifests as pixels erroneously reporting bright readouts in dark parts of the frame or dark readouts in bright parts. It looks similar to dead pixels, except Salt and Pepper noise will produce this effect randomly. Usually, analog-to-digital conversion or other errors in pixel interpretation cause this kind of noise.ShotImage via NeatVideo.Shot Noise is the main type of noise in darker parts of the image. Technically dubbed “Photon Shot Noise,” this type of noise results from the natural, inherent variation in photons striking each pixel at any given time, based on the exposure level. More technically, “statistical quantum fluctuations” cause this, but you get the idea.Shot noise is the biggest cause of the “blockiness” in the shadows of an underexposed or over-volted shot. At extreme levels, Shot noise becomes Salt and Pepper noise.QuantizationQuantization is a term non-specific to image noise. Essentially, quantization reduces a large set of (usually) continuously changing values in order to get a workable total sum value or smaller representative set of output data. Quantizers have a set number of possible output values, and as the data is processed, it’s effectively rounded to one of these values.Quantization is pretty simple to understand in video applications — millions of pixels’ individual readouts are quantized into a smaller representative set. In video circles, this is commonly referred to as “pixel binning.”In video, Quantization noise is usually undetectable as all pixels will be more or less affected equally. Errors can occur when the image clips far beyond the extreme ends of quantization values of the A/D converter. It can also be made significantly worse by strong noise of other types in the image.AnisotropicAnisotropic (An-Isotropic) noise arises when the sensor readout is sampled or quantized. This type of noise reduces perceived image resolution in affected shots by blending fine details together, creating patterns that aren’t actually there, or interpreting straight lines as jagged.Anyone familiar with video should get this one pretty quickly — just think of the terrible aliasing and moire of the first several generations of DSLRs.This type of noise in video cameras usually manifests when the native sensor resolution is much higher than that being recorded. Many older cameras opted to sample the higher resolution down to recorded resolution rather than simply scaling output to fit, causing much of the terrible aliasing and moire of early large-format video sensors.InterferencePeriodicImage via NeatVideo.Periodic noise is interference noise. It occurs when any number of natural or man-made signals interferes with the recorded signal. It typically appears as a fixed pattern overlay on top of the desired image.When working with video, it is essential to learn to spot the kind of noise that is affecting your image as you shoot. For many types of image noise, there are fairly simple ways to reduce or negate the negative impacts on the footage if you know how to spot the correct type as you shoot. If you are seeing noise in your image, remember to step back from the camera, make note of your environment, and then run through a list of each type of noise in your head to develop a strategy to reduce your headache in post. Technical remedies will serve you well, but never discount a little bit of creative ingenuity.Cover image via 25krunya.Looking for more video production insight?
