Formamidinium lead iodide is a very good material for photovoltaic cells, but getting the correct and stable crystal structure is a challenge.The techniques developed so far have produced rather poor results.The results were published in the journal Nanoscale on 15 March 2019.Perovskites are named after a mineral that has the chemical formula ABX3.'This formamidinium lead iodide material has very good characteristics, but the A position formamidinium ion causes instability in the structure,' explains Loi.Loi therefore set her PhD student Sampson Adjokatse to work to find a solution.
Sampling, or the reuse of snippets of a sound recordings, is a major component of popular music.Since the birth of musique concrète in the 1940s (a style of music based on the splicing and manipulation of tape), musicians have borrowed from each other to create entirely new works.Whether you’re taking an old school approach and hacking at your cassettes with a pair of scissors, or using a top of the range drum machine, programming and playing your samples can require an awful lot of background knowledge, both of the software and the techniques you’re using.So, what if you want to have a go at sampling without the hassle?The rings work in conjunction with the Specdrums Mix app, which features an in-app color-coded keyboard, with each key corresponding to a different musical loop or note – tap the key, and a sound is generated.Although Specdrums were designed with children in mind, they can be used by anyone to make music, and while they were initially made for the classroom, they’re are affordable enough for home music-making too.
AUSTIN, Texas—Growing up in a suburb of a suburb in Pennsylvania, my hometown's main street looked like you might expect: funeral home, gas station/convenient mart, VFW pub... and a taxidermy office.(Back then, the state even gave public schools a day off at the start of deer-hunting season.)But I had a pretty crude mental image based on context clues: antlers lining the walls, camouflage outerwear tossed over a chair, pickup truck parked out back with dead animals in the bed.Hosting its world premiere this week at South by Southwest, the new documentary Stuffed has come to fix this exact kind of misconception.If Stuffed's ~85-minute ride is to be believed, modern taxidermy is as much if not more about art and nature preservation as it is about dead animals.Watch enough of these industry-spanning documentaries on the festival circuit and you grow to learn the beats: introduce a variety of interesting personalities you may not believe all fit in the same field, explain the techniques requiring more skill and know-how than anticipated, show major use cases, go over the general history, sit in with the community during its peaks (competitions, major conventions, holidays, etc.
“Data mining” is the term commonly used for sifting through a database (internet, records or files) to find data which would be useful in identifying the purchase-related behavioural patterns of the consumers of a particular company.To make it even simpler, data mining involves drawing up patterns in information variables and units, organising them into coherent forms, analysing and drawing inferences from them.Anyway, to get back to the topic at hand, the techniques of data mining can vastly vary from complex to simple.With the help of this technique, common data characteristics emerge, which are then used to group the data into categories and cross-categories.It is mostly heavily used in fields related to forensics or weather forecasting.Huge sets of existing variables are mostly used for this purpose.
The process of sifting through a database such as files, records or the internet, in order to find data that would be helpful in identifying the purchase-related behavioural patterns of the consumers, who belong to a certain company, is known as data mining.In short, there are a lot of things that are involved in data mining, such as drawing up patterns in information variables as well as units, drawing inferences from them and also organising them into coherent forms.If you are to ask about the techniques of data mining, then let me tell you that it ranges from complex to simple.Of course, all the techniques are not meant for realising or discovering similar things.With the help of data mining, you can not only analyse but also process a large amount of data and develop them into patterns with regard to demographics and groups.Anomaly detection is a type of data mining which is mainly used to discover if there is any irregularity or abnormality in data.

Shooting time-lapse videos and pictures are not everyone’s cup of tea.To understand and acquire the technique of time-lapse photography; you need years of practice and research, of course.Apart from interest and knowledge, what else you need is an in-depth understanding of modern camera technology, a high-quality digital camera, and perfect location to shoot.You are wondering where to start?Well, whether you’re a pro of time-lapse photography or completely new to this field, below, we have collected few professional tips that will be very helpful for you when planning and implementing the techniques of Time-Lapse Photography.Let’s get started!Time-Lapse Photography TipsHave Right Time-Lapse Gears!Alongside a high-end DSLR camera, other essentials you need for the time-lapse shoot are a lightweight carbon tripod, Intervalometer, and Neutral Density Filters or ND Filters.Proper Framing Is The Key!Visualize the location, understand what you want to frame, and get the best shot!A simple click can make a massive difference between a mere picture and an epic one.Do Correct Camera Setting!Some people simply go for auto/priority mode and think Jpg files are the ultimate settings to get a time-lapse Construction Photography.
The algorithms guarding our inboxes have now developed to the stage that spam is usually kept at bay, but these auto-sorting processes aren’t perfect yet—if you’re not regularly opening up your spam folder to check on your email provider’s accuracy, you could well be missing some genuinely useful messages that you need to see.It’s still worth opening up your spam folder once in a while to check (spam is typically kept around for a few days before being automatically deleted).We also recommend spending some time training the spam filter on your email client of choice, taking a few moments to help it fine-tune the techniques that help it spot spam messages from the rest.To see the spam that’s collecting in the Gmail spam folder, you can follow this link in your web browser (remember the list of messages may well stretch to more than one page).Spam emails can be flagged from Gmail as well: Either select the message and click Spam, or go into it and click Spam.Gmail uses all this information to improve its spam-recognising technologies and to try and ensure fewer mistakes in the future.
It has the potential to ruin relationships, reputations, and our online reality.So far it has mostly been used to create altered pornographic clips featuring celebrity women’s faces but once the techniques are perfected, deepfake revenge porn purporting to show people cheating on their partners won’t be far behind.But more than becoming a nasty tool for stalkers and harassers, deepfakes threaten to undermine trust in political institutions and society as a whole.The White House recently justified temporarily banning a reporter from its press conferences using reportedly sped up genuine footage of an incident involving the journalist.Imagine the implications of seeing ultra-realistic but artificial footage of government leaders planning assassinations, CEOs colluding with foreign agents or a renowned philanthropist abusing children.So-called fake news has already increased many people’s scepticism towards politicians, journalists and other public figures.
We’ll be exploring the two major ways that you can add videos to your applications:Including one or more video files in your project’s “resources” directory.Dailymotion, using the Dailymotion Player SDK for Android.Just because your favorite video-sharing website isn’t included in this list, doesn’t mean you can’t use the techniques discussed in this article!You should consider bundling a video with your application files, if the video in question is required to deliver a good user experience, or it provides part of your app’s core functionality.Distributing videos as part of your application will also spare your users the overheads associated with downloading and buffering a video from the Internet, helping to preserve their device’s battery and data allowance.

Human right group Liberty is urging UK cops to stop using predictive policing programs that put a "technological veneer of legitimacy" on existing biased practices.The report centres on two types of predictive policing programs – predictive mapping, where police data is used to identify crime "hotspots", and individual risk assessment, where police have used algorithms to try to predict whether someone is likely to commit a crime.Liberty said, however, that forces' predictive policing methods are inherently biased – mapping programs rely on "problematic historical arrest data", while individual programs "encourage discriminatory profiling and result in opaque decision-making".This is combined with a "severe lack of transparency" on the use of the techniques, Liberty said, and urged the cops to "fully disclose" information about how and when predictive policing is used.The group submitted Freedom of Information requests to 90 forces in the UK, and found that 14 had deployed, were deploying or, or planned to deploy predictive policing.The rise in the use of the algorithms for policing comes as forces face tough budget cuts, and closer scrutiny from human rights activist.

Q Acoustics is following up its high-end Concept 500 floorstanders with a model that's even more striking: the Concept 300 stand mount speaker, announced Friday.The most attention-grabbing part of the 300's design is the new Tensegrity tripod stand, which is a combination of high-tensile wire and aluminum rods.The company says this stand is less subject to vibration than other types of speaker stands, and it is completely isolated from the cabinet by a spring-mounted plate.We know you're going to ask for it, but Q Acoustics says it's not selling the speaker without the stand.But the eye-catching stand is only a small part of the overall design, which builds on the techniques used in the Concept 500.The internally braced cabinet is constructed from three layers of MDF, each separated by a film of isolating Gelcore, which converts vibration to heat.

Academics from Northumbria University are to continue their ground-breaking research into the behaviour of liquids, leading a new project to investigate how to control the way liquids form into droplets.The team from Northumbria's Smart Materials and Surfaces Laboratory will work in partnership with Nottingham Trent University on the three-year study, which has received £700,000 funding from the Engineering and Physical Sciences Research Council.To initiate a process called 'Dynamic Dewetting,' the researchers will use electrical voltages to force liquids placed on certain types of surface to form specific shapes, such as triangles and squares, and then retract.This enables them to form the final shapes that you want them to appear in.Thanks to their work, the techniques they discovered have been implemented into software for use throughout the printing industry.Professor Glen McHale is the principal investigator on the study.
