Mostly Smartphone use Aluminium alloys and Magnisium alloy for light metal body. from where i will get data which mobile phone used which AL grade?

I want to measure the power consumption of RRC state machine

Hi all,

sorry for double-posting, but the "discussion topic" doesn't seem to get enough attention. We have recently started to work with Al single crystals for surface science experiments. Unfortunately, after a few cleaning cycles the crystal surface gets cloudy or "milky". Our typical cleaning cycle involves 1 kV Ar sputtering (ion current around 3-5 uA) x 30-60 min followed by annealing to 600-700 K (time varies, but typically not less than 15 min with somewhat fast ramping up and down, but no quenching). A high resolution XPS does not show any considerable amount of adsorbates or anything unusual whatsoever (some traces of oxygen which were there even for the mirror-like surface, some traces of carbon). Therefore, I suspect the crystal experienced some faceting/graining of the surface which resulted in that the surface has become mesoscopically rough. LEED spots have possibly become somewhat broader but this is really hard to estimate. Unfortunately, we had no time to perform AFM measurements on this surface. But it looks indeed as an annealing protocol is vitally important to keep the surface nice and well-defined. Therefore, I wonder if anyone else has experienced the same problem with Al (or maybe other crystals, too?) and/or knows how to overcome this issue? Maybe someone could share an annealing protocol or give a link to such a protocol if published? Tips and tricks? All meaningful opinions are welcome!

I really think the newest mobile phones have great computing power, just take a look at the incredible games and videogames that android and IOS phones are capable of running. But can we use that power for other tasks? Like high perfromance computer vision algorithms or efficient and mobile data analysis apps? Parallel computing is an interesting way to squeeze the power of hardware, so we can do parallel programming in mobile hardware? Is it possible to develop libraries like CUDA on mobile hardware?

dApps use the web3.0 for the P2P network. does mobile devices support this ?

How efficiently can dApps be used on smart devices, like mobile phones

A dial tone is the telephony signal sent by a telephone exchange, It indicates that the exchange is working.

As we all know smartphones are one of the most basic in every aspect of ourselves.. by using this how the service providers advertise their brand

in creation of image in the minds of general public .... Answers for this are welcome...

My research aims to evaluate how incumbent companies can face newcomers effectively based on a case study of the Mobile Phone industry.

In this regard, I am collecting data through a survey targeting Smartphone users to better understand the strategies adopted by Mobile Phone companies.

I personally believe it is impossible (or at least very difficult) to use probability sampling as the number of Smartphone users is very large (2.9 Billion users in 2017). I would like to use non-probability sampling, but I am not sure whether it would be acceptable in a research paper. What do you think?

At dinners, family get togethers, parties and weddings, everyone is busy using a mobile rather than talking or interacting with humans. Are we losing our sanity and socialization to the smartphones?
