1. The concept of the Internet of things has been put forward for many years. In recent years, with the popularity of big data and artificial intelligence, the Internet of things seems to fade out of people's vision. However, as a relatively mature technology, the Internet of things has been deeply implemented in instry. Many domestic instrial companies have launched IOT concept network in a shares and US shares. What are the instrial IOT concept stocks in 2018? Let's take a look at it today
PTC (NASDAQ: PTC) recently announced the publication of a series of research reports on the status of instrial innovation, which are published twice a year. Based on the data of PTC customer base, this series of reports provides objective analysis of the current development status and future promotion plans of instrial Internet of things (IOT) and augmented reality (AR) technology. Each report examines the instries that drive the popularity of these two technologies, the functions and use cases deployed across the blockchain, and the types of business value they bring
Mike Campbell, executive vice president of thingworx platform of PTC, said: "with the continuous maturity of the technology and business model of instrial Internet of things and AR, its popularity will show a rising trend. PTC combines market experience and massive penetration data to truly examine these rapidly evolving markets from a comprehensive perspective. "
as described in the "status quo of instrial Internet of things" and "status quo of instrial augmented reality", instrial Internet of things and Ar are no longer just promising emerging technologies. In 2018, investing in such technologies has become a key strategy for many organizations, especially for technology stocks that involve complex manufacturing and operational processes. Among the PTC customers who have adopted the instrial Internet of things or AR technology, 83% and 85% of the instrial Internet of things users and AR users have migrated to the full-scale proction environment or plan to complete the migration in the next 12 months, respectively< The main points of the report are as follows:
current situation of instrial Internet of things
1. At present, the instrial Internet of things is mainly used by large proct manufacturers in instrial procts (25%), electronics and high technology (22%), automobile (13%) and aerospace and national defense (11%)
2. The economic potential of instrial Internet of things has attracted the attention of the international community, and has spawned some global initiatives aimed at promoting the development of global instrial Internet of things< At present, most of the solutions are used in manufacturing and operation (48%), and the collected data can be used to improve the process, forecast the maintenance demand and improve the overall operation efficiency
Instrial Internet of things is no longer an emerging technology - it has developed into a mature and widely recognized stage. The instrial Internet of things is now being deployed in large quantities, involving a wide range of functions from proct development to manufacturing and services
current situation of instrial augmented reality
instries such as instrial procts (21%), automobile (11%), aerospace and national defense (8%) are leading the initial popularization of AR
AR is widely used in all aspects of the value chain, especially in service (19%) and manufacturing (18%)
AR can become a powerful tool for operation tips and guidance, thus providing an entry point for many organizations, especially those instries involving hundreds of key processes, such as real-time monitoring and improving equipment overall efficiency (OEE)
large scale investment in underlying hardware and software technology will promote ar penetration to a critical point, so that pilot projects can quickly migrate to the full proction environment< Relevant concept stocks:

if the atmospheric pressure is ignored: P = w / A2 = 5000 / (1000 / 10 ^ 6) = 5 * 10 ^ 6 Pascal = 5000kp
if the atmospheric pressure is not ignored and 100KP is added, the answer is 5100kp
(2)
when lifting heavy objects, the pressure of small plunger is greater than or equal to that of big plunger
the minimum pressure of small plunger is 5000kp * 100 / 10 ^ 6m ^ 2 = 500N
after 10:1 labor-saving lifting rod, Force F = 500N / 10m ^ 2 = 50N
so the minimum value of F is 50N
(3)
the simplest calculation is to use the function transformation:
force F work = the potential energy increased by the weight rising
suppose the weight rising h
then 5000n * H = 50N * 6 / 1000m = 0.3j
H = 0.06mm
PS: the value is so small, which is not consistent with the reality, and the rest of your data are very consistent with the reality,
so I estimate that your stroke s refers to the small plunger stroke
in this case:
use the total volume balance of liquid at both ends of the jack to list the equation
A1 * s = A2 * h
calculate: H = s * A1 / A2 = 0.6mm
if the atmospheric pressure is ignored: P = w / A2 = 5000 / (1000 / 10 ^ 6) = 5 * 10 ^ 6 Pascal = 5000kp
if the atmospheric pressure is not ignored and 100KP is added, the answer is 5100kp

3. The ring beam and structural column are not the load-bearing components of the building structure, but the anti-seismic structural measures, which should be equipped with grade, section and reinforcement at least without calculation; Frame column calculation, not read a few books on the line! We have to go through professional study and training. We only know some basic knowledge when we read a few books. Even students who can do homework in school only have theory, not practice.

You must have been near the ruins of the sea and caught the white guard
temporary relief method: drink milk. But it's going to be tiring again soon
permanent release method (step by step):
Step 1, take a sword with enough damage, put on iron armor all over, take food, pumpkin lantern, water lung potion, trap door, furnace (with body), charcoal, ladder
Step 2, observe the sea surface, as shown in the picture, find the one with the highest position and closest to the sea surface, In the past (you can build roads like me)
is there any other surprise? I don't know. I haven't found it yet, because I have just explored a small part of the underwater relics, which is only a small part! There are many other branches and deeper places I haven't seen yet
5. Eat milk. Milk can relieve any condition.
6. When I dig 11 layers, I look at the number of layers according to F3, or find a natural mine cave, and when I dig there is magma, I dig 17 at a time
7. It's an idiom
having more than one's heart but less than one's strength< In the Analects of Confucius, Li Ren said, "can you use your power in benevolence one day? I haven't seen the weak; I don't think so. "
[example]: whenever I'm more relaxed, I often come to give a confession, just '～'< Chapter 25 of a dream of Red Mansions by Cao Xueqin in Qing Dynasty; As subject and clause; It means to refuse politely

3, powerless
L ì b ù n é ng j í
definition: the power cannot be reached
Idiom source: under the volume of Wu Wang's killing Zhou Pinghua written by Wu Ming Shi of Yuan Dynasty: "the people of a city see that the city is destroyed by themselves, and they come to search and capture King Zhou. King Zhou sees that the army is so powerful that they can't reach it."9.
