Understanding and Choosing Oriental Design Rugs for Your Home

Oriental rugs are a great way to add personality to your home, and they can also be an asset—financially and otherwise. Many people have no idea about choosing rugs, however, and that’s a dangerous way to make any purchase. Read on for a primer on oriental design rugs and discover what to look for when you’re choosing one.

Persian vs. Oriental Carpets

A lesser-known fact about Oriental rugs is that only those made in Persia (now called Iran) actually qualify to be called real “Persian carpets.” Even though all Oriental carpets are not Persian, all Persian rugs are Oriental, so it’s a distinction you need to take note of. There are lots of other types of oriental designs, too, which are usually named after the towns and areas where the design originated many centuries ago. Real, authentic Oriental rugs can be made anywhere in Asia, but the majority come from the following countries: 1. Iran 2. China 3. India 4. Russia 5. Turkey 6. Pakistan 7. Tibet 8. Nepal The big question facing most buyers of Oriental rugs is whether they are authentically woven in the East or simply a reproduction.

How Rugs are Made

A real, handmade Oriental carpet is created by weaving wool, cotton or silk threads horizontally on a loom. The vertical strands that support the knots are called the warp, and after knotting the threads around the warp a tool called a weft is used to compact the strands together and keep the knots in place. The greater the number of knots per square inch, the finer the weave of the rug. The loose ends are usually left to create a fringe. Designs are inspired by the surroundings and everyday life, or cultural scenes and patterns. It takes months and years to weave a single rug, which is not only uniquely beautiful but practical and very durable.

A Reproduction May Look as Good

Imitation products are called Oriental-style rugs, and these are often factory- or machine-made using synthetic fibers and chemical dyes. They are much faster to manufacture and require less human labor, which makes them far more affordable. It can be difficult to distinguish a machine-made rug from a handmade Oriental reproduction, and Karastan carpets are particularly well-made. These were the first American-made, Persian-style products available, and initially used natural dyes and imported wool from Iran. The quality of materials resulted in the first-generation Karastan rugs becoming collectible items today. While Karastan no longer imports wool from Asia, it still makes use of high quality products.

Knot Count and Quality

The knot count of an Oriental rug tells the buyer how much work went into creating the piece. When you’re purchasing a new rug, one with 300 knots is considered a better quality and will be more expensive than one with only 200 knots. The more expensive rugs, both handmade and machine-made, typically use better grades of wool, good designs and coloration and colors that work well together and are pleasing to the eye. This affects the value of new rugs only, not pre-owned or vintage rugs.

Assessing the Value

Just because Oriental rugs are old, it doesn’t mean they carry a high intrinsic value. For vintage rugs, the resale value is determined by the age and condition, whether it is suitable for restoration, the rareness of the design and how well it works with modern furniture. Currently, popular investment rugs are those with large-scale and overall patterns, even if they don’t have a fine or intricate weave, the Turkish Oushaks, with their pale shades and large patterns, and bold geometrics with primary colors. Recently, there’s also a swing in interest to new, monochromatic rugs with minimal designs that are made in India, Pakistan and Turkey.

New Post has been published on https://weblistposting.com/mobile-telephone-alerts-bolster-road-stage-rain-forecasts/

mobile-telephone alerts bolster road-stage rain forecasts

Meteorologists have long struggled to forecast storms and flooding at the level of streets and neighborhoods, but they may quickly make headway thanks to the unfold of Cellular-phone networks.

This strategy is predicated at the physics of ways water scatters and absorbs microwaves. In 2006, researchers proved that they may estimate how much precipitation become falling in an area by means of evaluating modifications in the sign strength between conversation towers1. Accessing the industrial alerts of Cellular-cellphone groups became a primary stumbling block for researchers, but, and the field improved slowly. This is changing now, enabling experiments throughout Europe and Africa.

The era now seems ready for primetime. It can result in a unique flood warnings — and greater accurate typhoon predictions if the brand new statistics are included into cutting-edge climate forecasting models. Proponents additionally hope to apply this method to expand modern climate offerings in developing countries.

The latest entry into this area is ClimaCell, a start-up business enterprise in Boston, Massachusetts, that released on 2 April. The 12-individual agency claims it could combine facts from microwave indicators and different weather observations to create extra accurate short-term forecasts. It says it could offer high-decision, avenue-degree climate forecasts 3 hours beforehand, and could goal to offer a six-hour forecast inside six months. The business enterprise has yet to make data on its machine public or submit it in peer-reviewed journals.

ClimaCell will begin inside the USA and other developed nations, however, plan to transport into growing countries consisting of India later this yr. “The signals are anywhere, so basically we want to cover the arena,” says Shimon Elkabetz, ClimaCell’s chief govt officer, and co-founder. But the fledgling corporation faces opposition from researchers in Europe and Israel who’ve tested structures at more than one scales, including countries and towns, over the past several years. The scientists currently fashioned a consortium to improve the technology using open-source software. Coordinated through Aart Overeem, a hydrometeorological at the Royal Netherlands Meteorological Institute in De Bilt, the institution is searching for nearly €five million (US$five.three million) from the European Fee to create a prototype rainfall-tracking system that would eventually be set up across Europe and Africa.

“There is lots of evidence that this era works, however, we nonetheless want to check it in greater regions with big information units and one-of-a-kind networks,” Overeem says. Despite the fact that ClimaCell has made formidable claims about its program, Overeem says he cannot nicely assessment the organization’s generation with out gets entry to greater records.

“The truth that a begin-up agency and commercial buyers are inclined to invest in this technology is ideal information, but I accept as true with there may be room for all,” says Hagit Messer, an electrical engineer at Tel Aviv College, Israel, who led 2006 take a look at. She is part of the research consortium led with the aid of Overeem.

Preceding initiatives with the aid of members of the consortium that tested the technology have met with fulfillment. In 2012, as an example, Overeem and his colleagues confirmed that the generation may be carried out on the use level the use of business microwave statistics inside the Netherlands2. And in 2015, the Swedish Meteorological and Hydrological Institute (SMHI), based in Norrköping, launched a prototype real-time ‘microweather’ mission in Gothenburg. It collects around 6 million measurements in the city each day in partnership with the telecommunications business enterprise Ericsson and a cellular tower operator. The result is a minute by means an of-minute estimate of rainfall on a 500-metre-resolution map that encompasses the metropolis.

A brave new global Jafet Andersson, an SMHI hydrologist, says that the venture has helped to strengthen the era. As an example, he notes that microwave statistics regularly overestimate rainfall by as plenty as two hundred-300%. However, the group has labored out a way to correct for that bias without counting on reference measurements from rain gauges or floor-primarily based radar. This could make it less complicated to extend the era to developing nations.

“It’s going to make an effort, but we’re within the process of industrializing it on a rustic scale, or maybe a global scale,” Andersson says.

Researchers with the consortium have deployed the technique in African nations that do not have access to floor-based total radar and enormous rain-gauge networks. A crew led with the aid of Marielle Gosset, a hydrologist at the French Institute for Development research in Toulouse, proven an evidence-of-idea system in Burkina Faso3 in 2012 and has given that branched out to different nations which include Niger. Running with French telecoms large Orange, and with funding from the world Financial institution and the United Countries, her group hopes to enlarge into Morocco and start the use of actual-time microwave data in Cameroon this year.

The generation is attracting hobby in Africa because conventional climate tracking structures which include radar are too high priced, Gosset says. climate forecasts based totally on microwave indicators deliver developing countries a comparable system, however for less money, she says.

get entry to commercial information is getting simpler too. Researchers say that telecommunication businesses are starting to see the fee of liberating the statistics, and the consortium plans to create an important repository for processing the records. challenge scientists hope to create a version with a view to permitting a smooth partnership with the industry.

Xiaomi Mi 2 Auto Mode Leaves Air Unsafe for 86% of hours | Review

Ever since I coughed through a Beijing airpocalypse, I’ve been saying clean air doesn’t need to cost an arm and a leg. I set up the social enterprise Smart Air to put out open-source data on purifiers and provide low-cost purifiers to people in places like China and India based on that data.

So when the Xiaomi 2 air purifier came out for under $150 (10,000INR / 1,000RMB), I assumed it works just fine. But I had never gotten around to testing it—until now. And what I found shocked me.

The Test

Smart Air co-founder Anna ran a brand new Mi2 in the same 15m2 Smart Air test bedroom where we’ve tested the DIYs, IQ Air, Blue Air, and Philips. Anna ran six tests on auto mode and six tests on the highest setting (which the Xiaomi 2 air purifier oddly calls “Favorite mode”).

Anna turned the purifier on in the morning when she left home, and turned it off when she returned home, so there was no one in the home during the tests. The doors and windows were closed during the tests. (More details on the test method and all original data are here.)

A Dylos Pro tracked ≥ 0.5 micron and ≥ 2.5 micron particle counts during the test. Test data shows these 0.5 micron readings correlate highly with the US Embassy’s PM2.5 readings (r = .90).

As in my earlier tests, I calculated effectiveness as (the number of particles before turning the purifier on) versus (the average number of particles over the last four hours).

Results

The Xiaomi purifier scored as one of the worst purifiers I’ve ever reviewed. On average, it removed only about 60% of 0.5 micron particles over the last 4 hours of the test.

And oddly enough, the auto mode and the high mode results were nearly identical. That’s a mystery.

Here’s how the Xiaomi results compare to earlier results from other purifiers using the same method, same particle counter, in the same room.

The data shows the Xiaomi performed worse than the $30 DIY purifier I’ve been showing people how to make for years!

Below is a normal test day. I put a dashed red line representing the World Health Organization’s 24-hour PM2.5 limit (25 micrograms).

The Xiaomi Really Wants To Be in Auto Mode

What’s wrong? The key is that—even on the highest setting—the Xiaomi reverts back to auto mode after 3 hours (watch a video of it doing so here). To be sure this is what the machine was doing, we put the Xiaomi on the highest setting and tracked noise levels overnight from the Smart Air Lab.

You can see the noise remaining high for three hours, then it returns to the ups and downs of auto mode:

Here is the same graph with particle counts (measured by the Dylos). The particle counts rise sharply every time the machine turns off.

The data shows that the Xiaomi has a loose standard for “safe.” The Xiaomi is turning off when PM2.5 reaches 40 micrograms, which is far higher than even the WHO’s 24 hour limit. And it’s far higher than levels where we know PM2.5 has serious health effects from empirical research. Then it turns on again when PM2.5 gets up to 70 micrograms—almost three times the limit.

Really? It can’t be kept on high?

The fact that the Xiaomi air purifier can’t be kept on continuously all night is so strange that Anna asked Xiaomi customer service about it twice to make sure we’re not making a mistake. They confirmed that, no matter what, the machine will go back to auto mode after three hours (full transcript available in the supplemental materials).

How often is the air unsafe?

I calculated the percent of hours that the air was unsafe during the tests using this rule:

After the purifier was on for at least 1 hour, for any hour where outdoor air pollution was unsafe (> 25 micrograms – the WHO 24-hour limit), how many hours was indoor air also unsafe (>25 micrograms)?

The Xiaomi purifier left air unsafe for a shocking 86% of the time. The other similarly sized machines in my earlier tests left air unsafe only 7-16% of the time.

Maybe the Xiaomi Mi2’s auto mode is using the looser Chinese standard for clean air of 35 micrograms. Yet even with that high number, it was still above the limit 77% of the hours the Xiaomi Mi2 was running.

Update: we subsequently ran tests on the particle counter inside the Xiaomi Mi2, and what we found was shocking.

Wait, are you sure sure?

I wanted to be really careful about this review. I’ve seen other tests showing that the Xiaomi 1 works just fine, including these tests from Dr. Saint Cyr (although I’ve seen people write about flaws too, such as this guy who kept the filters wrapped in plastic, turned it on turbo mode, and the app told him his air got miraculously cleaner). So I double and tripled checked the data:

We tested with a different particle counter in a different room.

I re-analyzed the data throwing out any days with large fluctuations in outdoor air.

I analyzed days when outdoor pollution was low to average (< 150 micrograms).

I compared it to other tests done just two weeks before in the exact same room with the exact same particle counter.

None of these analyses changed the result (see details here). Note however, that we did only test one Xiaomi Mi2 air purifier, so there is a possibility another machine would perform differently. I invite anyone with a Mi2 to replicate my tests using the same method, and I’m happy to publish the results.

What now for Xiaomi?

From this data, my conclusion is that the fan and the filter are fine, but the Xiaomi air purifier has a programming flaw. Even if I use it on the highest setting, I’ll be breathing air far above the safe limit for most of the night. That’s a problem.

Is it just a Xiaomi problem?

To be fair, I cannot recommend any auto mode I’ve tested. I’ve tested the Philips AC4072 on auto mode, and it averaged 59% reductions in 0.5 micron particles, which is pretty close to the Xiaomi results. So I think this is more of a problem with auto modes rather than the Xiaomi specifically.

Yet I can still recommend the Philips. Why? It can stay in medium or high as long as you want, and test data shows it works fine all night as long as it’s not on auto mode.

I’m confident that Xiaomi can fix this flaw by simply allowing people to run it on high without reverting back to auto mode. But until that happens, I cannot recommend using the Mi2.

Open Data

As always, I’m publishing more details on the test method and the original data for fellow nerds.

Review Update: July 2018 Some users have reported that they are able to get their Xiaomi air purifier to remain in ‘high’ mode using the ‘automation’ feature of the app. For more information, check out this comment by Ryan, and this image showing how to set up auto mode. Breath safe!
