There are countless short videos on YouTube. It's a website for people to post video made by themselves. Many people make a lot of money through doing so. Then, who made the most over the past year?

    YouTube's top-earning celebrity is a 25-year-old video-game-playing young man who shows a strong sense of humor in his videos. He earned $12 million over the past year. Forbes magazine says Sweden's Felix Kjellberg, better known by his handle "PewDiePie", tops its first list of people who have turned short videos into huge piles of cash.

    YouTube stars make money mainly by getting paid to interact with products on their channels and sharing ad revenue(收入) with YouTube. Some also star in movies, write books, go on tour, or sell music. They're a hit with younger audiences and brands trying to reach the next generation of consumers.

    Two acts tied for the second place on Forbes' list, both earning $8.5 million: comedy prankster(搞恶作剧的人) duo Smosh(Ian Hecox and Anthony Padilla) and the Fine Brothers(Benny and Rafi Fine). Dancing violinist Lindsey Stirling ranked fourth with $6 million. Tied for fifth were comedians Rhett and Link(made of Rhett McLaughlin and Charles Lincoln III) and video game commentators(解说员) Olajide Olatunji, known as "KSI," with $4.5 million. Make-up artist Michelle Phan was seventh at $3 million. The No. 8 place was a three-way tie at $2.5 million shared by comedian Lilly Singh, or "Superwoman;" prankster Roman Atwood; and chef Rosanna Pansino.

    Forbes is best known for its list of billionaires and this list marks its first attempt at ranking YouTube stars. It says it measured earnings before management fees and taxes and came up with the figures based on data from online sources such as Nielsen, IMDb and interviews with managers, lawyers, industry insiders and the stars themselves.

At a time when industries are under greater pressure to reduce costs and increase efficiencies, more production facilities are turning to digital sensing technology to provide the real-time insights they need for improved performance. What if one digital sensor could measure multiple signals?

Yokogawa's DPharp (差压传送器) digital technology has the unique ability to measure two pressure parameters (参数), delivering reliable and accurate measurement of plant operations. The unique aspect of this digital technology is that it measures two parameters in one sensor module, providing additional insight into a plant's operations. It is the only sensor in the world that does this.

DPharp transmitters (发射器) use silicon (硅) resonant (谐振的) sensor technology to measure both differential (差别) and still pressure. The sensor consists of two H-shaped crystal silicon resonators that shake at a certain frequency and, when pressure is applied, the frequency of one resonator increases while the other decreases. By monitoring these frequencies digitally, both differential and still pressure can be measured at the same time. The frequency output is directly read by the central processing unit of the transmitter.

DPharp can be used in any processing plant across any industry—oil and gas to food and drinks. DPharp's unique digital sensing technology allows engineering firms and plant engineers to create designs that will equate to an average reduction of 40 percent. Where they would typically use five measuring devices, they are using three by using the multi-sensing technology. That is a significant cost reduction in the number of devices installed and the added benefit is that, as there are less devices, the engineering and design is less complex, which means less materials and less equipment to maintain. Furthermore, there are fewer transmitter spares required, which reduces costs. Tony Farah, Product Manager, said that more organisations are seeing the significant benefits of smart devices like DPharp.

While wandering around a Swedish Christmas market, you'll likely come across booths {#blank#}1{#/blank#} (sell) carved wooden horses, typically in an assortment of bright colors and floral patterns. These {#blank#}2{#/blank#} (tradition) Swedish toys are much more than a classic holiday gift or travel souvenir: the Dala horse has become intertwined (交织) with the very image of Sweden {#blank#}3{#/blank#}.

The little wooden horses of Sweden were originally carved by men that worked in the forests during {#blank#}4{#/blank#} winter. When they returned to their villages, they gave the horses to children as playthings. This was in the 17^th century during {#blank#}5{#/blank#} the horses were also sold at market in small towns and villages in the Dalarna region, in central Sweden. The horses were painted in bright colors that were inspired by the furniture in the region. {#blank#}6{#/blank#} (eventual) , even young children learned to carve wooden horses. 

The global attention didn't come until the 20 ^th century in the World's Fair in New York 1939. That was because an enormous painted Dala horse was placed outside the Swedish pavilion, which caused excitement throughout the crowds of {#blank#}7{#/blank#} (visit) . After this, the Dala horses were seen {#blank#}8{#/blank#} a symbol of Sweden and mass production of the horses started. Since then, Dala horses {#blank#}9{#/blank#} (be) popular souvenirs and inspired other products as well. You can now find anything from clothing to tableware and phone cases with a Dala horse {#blank#}10{#/blank#} (decorate) .
