9、lt that sweet was some sort of wonderful drug which gaveme the energy to function properly,to feel good and to perform at my best,all of whichseemed necessary for growth.So why should I avoid it?Years later,huge food companies,like General Mills and Post,began pumpingmore sugar into their products,a

17、ppealing.Stories exploring the subjecthave been around for hundreds of years.Perhaps the best known example is thescience fiction novel The Time Machine,which was written by H.G.Wells andpublished in 1895 for the first time.It was adapted into at least two feature films of thesame name,as well as tw

29、belief in what is real and what is not.I think thats going to be evenunimaginable.”To test how believable these reviews came across,the researchers invited 40volunteers and had AI generate five fake reviews for 40 actual restaurants.Thevolunteers were asked how useful they thought the reviews were a

30、nd whether or notthey thought they were fake.The AI reviews ranked as “effectively indistinguishable”from real reviews,according to the study.Further,the fake reviews were given a 3.15“usefulness” rating,compared to a 3.28 rating for human reviews.1.Whatcanthenewartificialintelligencesystemdoaccordi

35、er and theInternet.They can be accessed and controlled remotely by computer or smartphoneapps.But a group of electrical engineering and computer science professors in theCase School of Engineering have been experimenting with a new suite of sensors (传感器).This system would read not only the vibration

36、s (震动),sounds and even othermovements associated with people and animals in a building,but also any slightchanges in the existing electrical field.While there still maybe a decade or so away,the home of the future could be abuilding that adjusts to your activity with only a few small,hidden sensors

37、in the wallsand floor without the need for monitoring cameras.“We are trying to make a building that is able to listen to the humans inside,”said Ming Chun Huang,an assistant professor in electrical engineering and computerscience.“We are using principles similar to those of the human ear,where vibr

38、ationsare picked up and our algorithms (计算程序) recognise them to determine yourspecific movements.Thats why we call it the Internet of Ears.”“There is actually a constant 60Hz electrical field all around us,and becausepeople are somewhat conductive,they short out the field just a little,” Huangsaid.“

39、So,by measuring the disturbance in that field,we are able to determine theirpresence,or even their breathing,even when there are no vibrations associated withsound.”Huang said they have used as few as four small sensors in the walls and floor ofa room.Asforprivacyconcerns,thesystemwouldnotbeabletoid
