Tips to buy a washing machine

images-6Material of the drum or tub

The tub can be made of plastic, porcelain-enamel or stainless steel. The first two are cheaper. Plastic tubs are more durable than enamel ones, which can chip and rust. Stainless steel tubs are the best as they are the most durable and can withstand high spin speeds.

Wash settings

Most machines have preset wash programmes, such as ‘gentle wash’ for delicate clothes, and water level options. You can customise and save favourite settings. These can be adjusted through rotary controls, a touchpad or a touchscreen. The first type is the cheapest.

Spin cycle

The spin cycle for drying is measured as revolutions per minute (rpm). The higher the rpm, the better it will dry your clothes. However, this will depend on the types of clothes. For delicate clothes, the spin cycle is 300-500 rpm, while for thicker items, such as jeans, it is about 1,000 rpm.

Manufacturing without Inhibiting Machining

unduhan-4Mitsui Seiki is a machine tool builder that aims to excel in the area of precision. It provides machines, often custom-engineered, to meet machining challenges related to high-value parts with particularly demanding tolerances. Therefore, the company’s introduction of additive manufacturing as a capability it can now deliver might seem like an odd fit. Additive manufacturing—building up parts or features through a controlled process of adding material in layers—cannot by itself achieve anything like the fine tolerances that machining can.

But Robb Hudson, technology and business development manager for the company, says additive manufacturing is an addition to machining that brings both design freedom and process efficiency to complement machining’s precision. And by consolidating more of a part’s processing into a single machine, it potentially reduces part handling, which facilitates precision as well. During the past year or more that the company has been preparing to come to market with additive capability, he says, it has been experimenting with how to use metal cutting and metal deposition effectively within the same machine tool, without having to compromise the effectiveness or

Improve Machining Times

images-5Open Mind Technologies USA will present HyperMill Maxx Machining, a set of high-performance strategies within HyperMill CAM for improved roughing, drilling and finishing.

Maxx Machining Roughing is a high-performance roughing module based on Celeritive’s Volumill toolkit. This module is designed to provide increased cutter life while reducing roughing times. It can be applied to 2D pocketing routines, 3D stock roughing and five-axis shape offset roughing.

Maxx Machining Drilling is a technique used to open holes for roughing using a five-axis helical drilling processes. It can use standard end mills, and avoids recutting chips, thus protecting the cutter.

The Maxx Machining Finishing includes a set of finishing operations focused on the application of conical barrel cutters. This can be applied to large planar surfaces found in mold tooling, as well as in aerospace structural components and other large ruled or sculpted surfaces.

Advantages Associated With WordPress

The WordPress CMS platform appeared in 2003 and ever since then it kept gaining popularity. Nowadays, it is the preferred platform used by many businesses. Statistics show that it helped in creating over 70 million sites all around the world. When creating a blog you are interested in making everything as simple as possible. WordPress is basically the most powerful and easiest to use website and blogging content management system.

Building a site is definitely something that should be handled properly. In so many cases we are seen with huge problems because people do not really understand what they should do. Since everything starts with choosing the platform you use for the blog, we have to talk about WordPress and what it can offer. The main advantages associated with this CMS are the following.

It Is Completely Free

If you were to pay a developer to create a specific CMS system you would end up having to pay thousands of dollars for the features that are available in WordPress for free. This is obviously one of the biggest advantages that you can take advantage of.

EDIBLE BATTERY FOR POWER

Imagine taking a pill with an ingestible sensor that takes measurements and sends information wirelessly to your doctor, or a pill that senses changes in your gut microbiome and adjusts its dose accordingly. Ingestible medical devices promise such applications, and many more, but a big challenge is making their power sources safe for our bodies.

“For decades, people have been envisioning that one day, we would have edible electronic devices to diagnose or treat disease,” materials scientist Christopher Bettinger said in a statement. “But if you want to take a device every day, you have to think about toxicity issues. That’s when we have to think about biologically derived materials that could replace some of these things you might find in a RadioShack.”
Bettinger and his team at Carnegie Mellon University have taken a big step towards that goal. They’ve developed a battery out of melanin, a pigment that occurs naturally in our skin, hair, and eyes. Melanins protect our bodies from free radicals, but they also bind and unbind metallic ions, a chemical process crucial to the function of batteries.
The team built the batteries using melanin and other biocompatible materials such as manganese oxide,

How to hunt out brain tumours

Investigating the deepest regions of a person’s brain is no easy task. Tiny robots crawling through it could help.

It’s a tantalising idea, but one problem is how to direct such nanobots on their travels. One way to do this would be to program them to search like bats hunting for prey, says a team who have created a computer simulation of this, and hope to trial their method in people in a couple of years.

Engineers around the world are working on various designs of nanobot, particularly ones that could release medicines inside the body. Panagiotis Katrakazas at the National Technical University of Athens, Greece, is more interested using them to detect brain damage, which can occur deep in the brain and be difficult to see in brain scans.

“The idea would be to inject nanobots to pinpoint the exact location of damage, which could then be targeted with medicine or surgery,” Katrakazas says. His team are working to develop nanobots that crawl along neurons, pinching them to see if they are healthy or not – healthy ones respond with an electrical signal, but damaged ones do not, he says.

QUANTUM SATELLITE IN SEARCH

The Quantum Experiments at Space Scale (QUESS) satellite, weighing 500 kg, contains a quantum key communicator, quantum entanglement emitter, entanglement source, processing unit, and a laser communicator. At its orbit 1,000km above Earth, it will transmit quantum keys between ground stations in China and Austria. (The Austrian Academy of Sciences is a partner in this effort, along with research in other quantum technologies like photon teleportation, transmission reduction error, and random number generators.)

Quantum keys are encryption keys (when encryption keys are applied to an encryption algorithm, they decrypt and encrypt information), which are linked to particles that have been entangled at the quantum level. Particles in quantum entanglement share a quantum state that will collapse upon observation. This means that legitimate users of the quantum communications system will notice if they’ve been hacked, from the quantum state collapsing due to another party viewing the transmission.

Additionally, the properties of quantum mechanics make it virtually impossible to reverse engineer a quantum key generated through quantum entanglement. Quantum keys are thus theoretically impossible to crack by even with quantum computing — a theoretical form of supercomputing that promises to defeat traditional forms of encryption. Importantly, though, quantum

Why the robot guards is not enough to stop people stealing

Would you do what a robot told you to do? If people stealing food right under the eyes of a bot is anything to go by, RoboCop is still a long way off. In a twist on a common psychology experiment, in which a picture of a pair of eyes seems to make people behave more honestly, Guy Hoffman at Cornell University in Ithaca, New York, and his colleagues stationed a robot guard to watch over a table of snack food labelled with a “reserved” sign in a student common room.

The team used a mObi robot made by US robotics company Bossa Nova. This does not have a threatening appearance, like some security bots — such as the Knightscope (pictured) — but it has eyes that looked around the room. Still, it proved a poor deterrent. Seven per cent of passers-by still helped themselves to food, only slightly fewer than the 8 per cent who took food when the table wasn’t guarded at all. In contrast, only 2 per cent of people pinched a snack when a human was sitting at the table.

Hoffman is interested in finding out how people act around robots in everyday settings. “We talk

YOU MUST KNOW ABOUT SELF DRIVING

Uber is almost undoubtedly the biggest name in ride-sharing in the 2010’s and the company is looking to go even bigger. While the company currently relies on hiring drivers to bring passengers from point A to B, Bloombergreports today that self-driving Uber cars will hit Pittsburgh as early as this summer. That beats competitor Lyft’s goal of getting automated vehicles on the road by 2017 by almost half a year.

The choice of Pittsburgh can be traced back to Uber’s close relationship with Carnegie Mellon. While Uber didn’t quite partner up with the university, it didpoach 40 Carnegie Mellon researchers to work on autonomous vehicles for the startup. The researchers hired away hail from CMU’s robotics center–many of which were software developers.

Uber has retro-fitted Volvo XC90 sport-utility vehicles to support its driverless car software. Autonomous Ubers will be sent to Pittsburgh-residing Uber users at random, meaning you won’t be able to specifically choose the cars currently. And the rides, for now, will be free of charge. While the cars will drive themselves, a human being will still sit in the drivers seat along with a person riding shotgun taking notes on a laptop about the

UNBREAKABLE GENIUS OF TECHNOLOGY

Down the hall from Mark Zuckerberg’s desk sits a virtual reality studio. Foreign heads of state and other dignitaries have been known to lose themselves here in games of zero-gravity Ping-Pong and the real-seeming experience of firing virtual fireworks at each other. Such are their number, and frequency, that on an early summer morning Zuckerberg is at a loss to remember—or perhaps too diplomatic to divulge—one of their names. He does, however, recall the anecdotal nugget of the man’s visit.

“He wouldn’t leave,” says Zuckerberg, sitting in a glass-walled conference room in Facebook’s cavernous and almost factorylike headquarters in Menlo Park, California. “His aide was like, ‘Mr. Prime Minister, you have to take off…you’re two hours late for your flight.’”

That is exactly the reaction that Zuckerberg—the 32-year-old, still jeans-and-tee-clad creator and CEO of Facebook—wants to elicit from millions of people he hopes will strap on his Oculus Rift headset. But there’s way more to it than a feeling of presence with Ping-Pong opponents. Zuckerberg wants Oculus, or some future iteration of it, to replace our laptops, our smartphones, our televisions, the art on our walls, and, in some cases, seeing our friends in the flesh.

WhAT’S THE CODING DIVERSITY SAY

“You can absolutely be what you can’t see! That’s what innovators and disruptors do,” Kimberly Bryant tells me, dismantling the clichéd quote about role models for the underrepresented in STEM (science, technology, engineering, and math). Lack of role models didn’t stop Bryant from founding Black Girls Code, a non-profit working on adding a few more shades to Silicon Valley’s color palette. The company, founded in 2011, is dedicated to teaching girls K-12 how to code, and has grown to be 6,000 students strong. With chapters in San Francisco, New York, and even Johannesburg, South Africa, Kimberly Bryant is helping give the tech industry a much-needed diversity upgrade.

I mention that Neil deGrasse Tyson agrees—if he’d waited for a black man from the Bronx to become an astrophysicist, he wouldn’t have pursued the field. Bryant acknowledges how difficult it can be to make your own road without having anyone who’s walked a similar pathway previously. But she also points out the different levels to the pedestal we place role models on. “Tyson surely didn’t have any direct role models, but as a man he still had other men in his field doing what he wanted.”

SYSTEMS WERE INFILTRATED BY FOREIGN HACKERS

Two state election databases have been hacked by foreign hackers, according to a new report by the Federal Bureau of the Investigation. The FBI says these actions may have been carried out by either Russian government hackers, or cybercriminals who are seeking to find and use protected tax information.

The report does not specify which states, though they’re likely to be related to previous cyber attacks that impacted Illinois and Arizona. In Illinois, voter registration records for some 200,000 individuals was discovered to have possibly been stolen before the database was shut down last month. The FBI has already revealed that eight IP addresses have been tied to the Arizona and Illinois breaches. Officials are examining whether or not these IP address links are also a part of this hack — and possibly others to be attempted on other states in the future.

There are plenty of bots working today to produce basic, numbers-driven reports on sports and finance results, but the Olympics showed that one robo-reporter can be quite prolific. A single Chinese bot named Xiaomingbot produced 450 stories about results from the games.

It’s important to note, as Quartz does, that for most

Deliver Flexibility to Shop Floor

CEO Stewart McMillan still remembers his father looking at him and asking, “Are you sure about this?” when the family-owned company located in Valparaiso, Indiana, bought its first CNC machine 40 years ago. “It was a huge step, but giving people the proper tools to do their jobs is essential to being productive,” Mr. McMillan says.

That line of thinking helped him recognize that the shop’s robots had limited capabilities because of their dedication to just one machine. “So, what happens is the machine wears out first, and now you have a $100,000 robot that you cannot do anything with,” Mr. McMillan explains.

After hearing about collaborative robots that could be used in a much more flexible manner, the company decided to explore the technology by getting a Universal Robots demo in the shop. According to Production Supervisor Cory Mack, his colleagues were trying to program it and make it work within minutes of its arrival.

“The Universal Robot is so simple and non-intimidating that our programmers were already in the mindset of ‘I don’t need any guidance; I can do this on my own.’ It was almost like a PlayStation video game, where they

How to Optimized Machining out of the Box

Every milling process has a spindle speed, or a set of spindle speeds, at which it inherently wants to cut. Run at one of these particular speeds (the “sweet spot,” if you will), and chatter quiets down. Heavier cuts are possible. Higher tool life is achieved. Particularly above 10,000 rpm, the chance for enhanced cutting performance at these dynamically stable spindle speeds can be pronounced. Finding and running at these speeds is perhaps the most accessible productivity enhancement that hardly any shop is using.

Why are dynamically stable milling speeds not more widely used? The corresponding organizational complexity is part of the reason. Those seemingly magical spindle rpm values are different for every different combination of machine, toolholder, cutting tool and tool overhang length. Finding the right speed for one combination is not difficult—a measurement using commercially available frequency-analysis equipment can determine it in minutes. (Involving a tap with a small hammer, this measurement is commonly called a “tap test.”) However, the shop that is intent on using stable speeds has to determine this ideal speed for every combination of machine, tooling and stick-out length that it wants to optimize. It also has to apply the discipline

Google Street View to Market

How do you let potential customers see your machines and manufacturing capabilities when they can’t spend the time and money to leave work and fly across the country to visit your facility? Gilman Precision of Grafton, Wisconsin, is taking an unusual approach to showcasing its capabilities: offering a virtual tour using Google Street View, a web service that provides 360-degree views of specific locations. In this instance, the location is Gilman’s facility.

Google Street View wasn’t Gilman’s first attempt at a virtual tour. YouTube videos ultimately fell short of expectations because they didn’t allow visitors to stop and stare at things that piqued their interest. So after the Milwaukee Chamber of Commerce sent out information on using Google Street View to tour restaurants, bars and other locations, Gilman reached out to Google to see if the company would consider a street view of a manufacturing facility.

To start the process, Gilman got bids from some Google-certified photographers in the area. (A searchable list of Google-certified photographers can be found at short.mmsonline.com/streetview.) According to Douglas Biggs, Gilman vice president of sales and marketing, prices depend on the size of a facility and how many photos would be necessary

The best machines for interaction

A team of European researchers have embarked on a landmark study that could potentially pave the path to ’emotional’ machines which may interact with humans using voice.

“As our interactions with machines get more and more pervasive, it becomes harder and harder to ignore the emotional element. Taking it into account will become a routine part of computer science courses and computer development,” says Professor Roddy Cowie, coordinator of the EU-funded Humaine project.

In effect, machines that feel may no longer be confined to science fiction.

Humaine has set up teams from disciplines as different as philosophy, psychology and computer animation to create the building blocks or tools needed to give machines so-called soft skills in order to make human-machine interface more user-friendly.

“We have developed systems for recognising emotion using multiple modalities and this puts us very much at the leading edge of recognition technology,” says Cowie.

“The people who know about communications feed information to people whose job it is to get computers to generate sophisticated images,” he adds.

Even as there are already concrete results,
