It is very difficult to produce any product in one direction by any company, when we work on a project then we focus on different prospective of our project at the same time if we wouldn't focus at the same time it will harm or late or costly as compare to dimensional product. So our science technology is improve day by in beginning our companies’ works on 1D but they quickly realize, it is difficult so they change in to 2D and then after 2D technology science improved, and into convert three dimensional. In these days 3D technologies are very popular because in 3d you decide every decision before investment you will make and validate your project design and architecture on compute in which "Computer Aided Design" used. In 3D we have abilities to make layers and focus in three direction x,y,z of our project.
What's 3 Dimensional (3D) Printing?
We already read about 3D or other dimensional concepts, now we will explain 3D printing, 3D printing is a method/process in which we make three dimensional products using digital files. These products achievement is accomplished by additive processes. In this process, we change raw liquid material in specific form and lying down in persistent layers using computers, until your product is fully shaped. Every layer looks like as horizontally Intersection of the possible object. It also based on 3D model and electronic soft data. These printers work as robot. We have ability to create solid object using 3D printer.
How 3D Printer work's?
3D printer depends on three basic principles Modeling, Printing and Finishing. First we do modeling of any product you want to make, in modeling we use (CAD) Computer Aided Design in modeling software or we create design using 3D scanner in which we create digital clone of our object. Some companies used digital cameras or some are used photogrammetry software's. There are a lot of procedures in modeling; all are used for virtual design. When we make design through 3D Scanner, In 3D scanner there are various technologies used for example: "Time-of-flight", "Triangulation", "Strengths & weaknesses" etc... These techniques used in Non-contact active. In Non-contact passive "User assisted" technique used it works on image-based modeling. After modeling we print product in successive layers until we create own choice product. After printing we finishing our product using polish and colors and a lot of other things for finalize our product. There are several type of Printer works on several places now we will describe working of Material Jetting and Sheet Lamination, Basic concept of all printer is same for all printer (Modeling, Printing & Finish).
In Material Jetting process build and support material droplet via diameter nozzles, this printer work on same concept like paper inkjet-printer only difference in both in 3D printer work on successive layers for in creation of any 3D object and then UV light release on product for make product hard.
In Sheet lamination process deal with sheets (of metal, paper or polymer) those are bound with each other using external forces. Especially in metal sheets we weld sheets using ultrasonic welding layer-by layer and after welding meted by CNC for changing in several form according to out requirement. W we use paper sheets then we use glue and cut in to several shape using different blades according to requirement. There are several companies use this technology but one of big company is "Mcor Technologies".
There are a lot of other 3D printers available in market in reasonable (cheap) price. If you want to make your own business you should watch 3D printing field it is new technology and have more scope as compare to other fields.
Heat is very important for human, so we produced heat using different way for according to our purposes for example some use fuel (solid/ liquid) for producing heat, some use wood, and in developed countries, there are a lot of new technologies for this purpose but the problem is not this how you produce heat in winter season or according to your need, problem is how you will produce heat in cheap money and in better ways. So, some Scientists always working on energy topic, so they find another way to warm room using air, before few years in winter we use electric heater or gas heater or other old ways to produce energy. Problem is that, in the world’s lot of big countries are in energy crises so they want to find cheap way to produce heat energy. This topic is about Heat Pump, this is a new way for common home use it is also cheap way. Now we will describe how air heat pump efficiently uses.
What is Air Heat Pump?
Pump function is very simple, transfer heat from one place to another, but know we talk about a pump who transfer heat from outside building to inside (outside sun heat), with this pump full mechanisms of generating heat is also install. Heater generates heats and pump transfer heat using air. There is also air pump available in market that only transfer heat outside building to inside only, these pump not working in too cold areas example snowfall areas. Usually for only air heat pump use refrigerant system with little compressor, and they suck heat from one place to others.
How to Work a Heat Pump?
Heat pump works on very basic and simple concept, in water heat pump main component are radiator, water tank, water pump, flame burner, fan etc... Basic idea is that, burner is fixed below water tank & connected with water pump and radiator using pipes, from one side cold water enter in water tank and the other side normal water comes back from radiator in water tank, this water makes cycle through water pump and radiator and water is back in water tank. In this system main role is done by fan. May you know in radiator there are so many thin metal pipes fixed when water passes through this pipes water is start changing temperature (hot to cold) because air passes between pipes but when we on fan, it force cold air convert to warm air. These airs changed your cold to warm room, office or etc.
But on the other way there are also available heat pumps these work efficiently but in these heaters burner, and water pump is not use like water heat pump. In which air condition concept is uses, because we know in our home heat is already exists generated by Sun shining, Stove, Oven, Human body, or some electrical appliances example (fridge, refrigerator) so in summer we use air conditions for suck this hot heat and remove from your room or house, just opposite this concept in winter and you should understand this air heater working. You can use any normal air condition for heat generation or make easily heat pump.
How to check heat pump efficiency?
Those heat pump who are not efficient and not have ability for fulfill written information specification 100% may be these are also acceptable after installation but it is costly, they take more time for warm your room. So we will describe defect prevention or containment that cause for heat pump efficiency lapses. There are some extra benefits of air heat pump because it use in winter as heat generator pump but in summer work as air conditioner.
You see graph i think you understand heat pump output and temperature behavior now we will move forward how to deal with. First you should chose some branded or good company who will provide good quality product, then secondly give contract to any licensed, qualified and experience technician to fit heat pump in your home/office or where you want. And after install this service, don't forget inspection method. After all these process if your heater take a lot of time to warm your home/room/office then start duct testing because if any door or window or duct stay open, may it cause you as extra bill and it will work slowly as heater or air conditioner.
How to tell you If a Website Is Safe or not? – 7 Things always Remember
“Security” is one of the most important factors, when it comes to websites especially. And with so much of spams out there, it is hard to know if a website is trustworthy or not. Most websites are made to look great and respectable, however, are dangerous to use. Even the most excellent security software cannot protect a user from problems he or she encounters after clicking unsafe links. Such links often appear as shortcuts to shocking news, funny videos, “Like” buttons or awesome deals but are actually designed to take away all your sensitive details or to even hack your computer. Chances are that your friends or relatives might unknowingly pass such unsafe links via Facebook posts, instant messages or emails. You will also come across unsafe links in site’s ads & search results. So, how to tell if a website is safe or not? And how to avoid suspicious clicking links? Here is something for you to learn.
Tell me how a Web site is secure?
You should be very cautious while using a website, especially if you are about to give your personal details like address, contact number, bank account number or credit card number. Chances are that it could be phishing scam, wanting your personal data. Be aware of websites, which often seems to be genuine but have different pop-ups and intrusive ads or asking you to install plug-ins. So, it is extremely important to make sure if a website is safe before using it.
If you feel that a source link is phishy, as in it must have come from any unrecognized email, then never do the mistake of clicking it until you have confirmed that its safe. Just follow the below listed tips to know if it is safe or dangerous.
1. Hover over a Link
At times, a link might mask the site to which it exactly links. And if you hover the link, you will observe a complete URL to its destination. This is displayed at the bottom left corner each time you hover it. So, You must be capable to see where it will redirect it to without even clicking it.
2. Analyze The Link First – Is It Shortened?
To copy a link for further analysis, without even visiting the website, just right click it & select “Copy link address” (if it is Chrome) and “Copy link location” (if it is Firefox). If the link appears shortened, you should un-shorten it first prior testing it. Just paste your shortened link in the box that appears on the website. It then provides the actual URL.
3. After You Have Un-shortened the URL, Use Link Scanners
I am sure you must have heard of “link scanners” somewhere. These are plug-ins and websites, which allows a user to enter a suspicious URL or link to check if it’s safe or not. You will find thousands of free link scanners online but I personally recommend using URLVoid first. This scans the link with multiple services like Google, Norton SafeWeb, MyWot and reports it quickly. Another helpful source is Sucuri. This website automatically expands short links and uses many secured services to determine if a link is dangerous or safe.
You could also copy a link in Comodo Web Inspector to know how safe it is. But this analysis might take some time because it runs in-depth looking for any malicious content. If you want the process to be quick, then I would suggest using Zulu URL Risk Analyzer simultaneously. However, once the Comodo Web Inspector completes, it presents you a detailed report. If the website has rated it — High Risk, then the link is dangerous. Now for the Zulu URL Analyzer, it also utilizes multiple methods for analyzing a website’s link. Once the process completes, Zulu provides you a total risk score. It ranges from 0 – 100. More is the score, higher is the danger level.
4. Check with VirusTotal & URLVoid Too
The next step on how to tell if a website is safe or not, is to use online tools like URLVoid and VirusTotal. You have to check the website against databases too. Just copy and paste a URL in VirusTotal. This helps you know what reputation the corresponding website has & if a particular domain has ever been blacklisted. Select “rescan” if the website has already rated it. If the website is known to be unsafe, then it will more likely be flagged by other services too. But, even if everything comes out clean, this does not mean that it is 100% trustworthy.
Also copy and paste the site’s URL on URLVoid. If you have used it already in the above step, skip this. As said earlier, this tool uses multiple approaches. This service also checks for blacklists and if presented, select “Update Report” option, as this provides you with most updated results. And, on the top, you will see information regarding when the domain name was originally registered.
5. Check The Website’s Reputation
When you get the URLVoid results, look at the bottom. It shows you WOT (Web of Trust) ratings. This trust score is extremely helpful to learn if a website
is trustworthy or not. However, clicking the button on the 3rd column brings WOT scorecard of a website, where you will see a detailed information. It includes comments. Reading them gives you an idea of how the site is.
6. Pay Attention to the “Lock” Icon
Few websites use secured connections. This might be very important, especially if you are making online purchases or giving out your personal information. To know if your browser is actually viewing a secured website, just look at the top left right corner of your URL box. You should see a small globe icon, which basically describes the zone you’re in. If you observe a yellow-colored padlock icon after entering the link, the website you view is “secured.” However, if it is empty, it means that the respective website doesn’t have a secured connection to your browser. There is another way to check this as well. There is this standard among different browsers to show a “lock” symbol somewhere inside the browser (but NOT in your web page area!) Say for example, Internet Explorer shows the “lock” picture at bottom right corner of your browser window while Firefox shows at the bottom left corner.
And this “lock” icon isn’t only a picture. It could reveal a lot about a website’s security. You should be aware of all this because many fraudulent sites are designed with a bar, which is usually at the bottom of a web page. This bar is too often imitating your browser’s lock icon. Hence, it is essential to test its (lock icon) functionality. All you have to do is – Double-click the lock symbol to see more information.
7. Ensure That the SSL Certificate Is Genuine Prior Making Purchases
You will surely know if a website is safe or not after you use the above online tools. However, if none of the above-mentioned methods work or you are not able to tell if a website is safe, and then do this before transmitting any of your sensitive details to a website. The first step is to ensure if a web page is SSL secured. This most often includes for web pages asking you to provide your credit card number, bank account details, contact number and so on. Observe the URL properly. If it begins with https://, the page you’re seeing is secured and trustworthy. And no user other than you can view your personal information you’re submitting. But, there is a subtle risk you need to be cautious of. You actually have different SSL certificate types, each providing varied trust levels. For instance, an extensive validation certificate guarantees that a particular business is legal, while other certificate types are validated only with respect to a domain and not the operators / owners. Remember this always — phishing websites are known to purchase low-level certificates just to trick users in believing that they’re trustworthy, however are not!
9 Other Free Online Checking Services To Reveal a Website’s Safety
Some antivirus offers network protection, which checks if a file and website is safe / not. Even browser add-ons notify users if a web page is 100% safe to use. Most browsers automatically block unsafe downloads or bad websites. However, if you still want to know better about a site, then use any of the below listed online services.
1. Blacklist Doctor
2. Google Safe Browsing – A service from Google. All you have to do is enter a URL or link at the end of this [http://google.com/safebrowsing/diagnostic?site=]
3. LinkScanner
4. HpHosts – To see if a website is listed malware, phishing or rogue.
5. Norton SafeWeb SiteAdvisor
6. sURL
7. Unmask Parasites – This tells if a website has hidden parasites.
8. vURL Online – It dissects web pages if they are suspicious or malicious.
9. WOT Web of Trust – Use this to check if a website is spyware, malware, phishing or rogue
US military officials introduced tracking system known as GPS Global Positioning System. It is fully functional in 1995. Initially it was not for common use, only for us military but later on they decides to give access everyone in the world's and GPS provided to a lot of companies for used it in your products for common person use. Today it is an important feature in every mobiles and also used in some other services/devices for example buses, cars, laptops or other in tracking system appliances, GPS is also known as navstar navigation system. GPS directly connected with the satellite. In these days a lot of counties have own satellite for this purpose. It help people's in a lot of departments, majors problem is in this systems is accuracy that's way other countries send own satellite to space for example Russia make own system using "GLONASS satellites" it gives very accurate in major areas.
How Global Positioning System GPS Work's?
In these days, there are a lot of "Global Positioning Systems", GPS uses easy concepts but its instruments and technology is complex. There is basic main formula for all GPS systems. For example Android mobile those have locations trace ability known as GPS satellite signals receiver, These GPS satellite receiver use for receive signal from satellite with the exact transmitted time and place then android or computer software calculate distance speed, turning points according to the given maps, satellite continuously send signal to receiver hardware.
In these days this system works with at least 31 satellites orbits with 55 degree inclined equator. These satellites exist about 20,000 km from Ground level earth's and makes orbit 2 times a day. These orbit are created by us so Six satellites are always focus on famous places on the earth for hurry & accurate result access. Satellite sends signal to your receiver these signals travel with the speed of light. GPS track you location using a process known as trilateration. Trilateration is one of main algorithm concept in this system working. There are required 2 types of data by GPS receiver one is Almanac and 2nd is Ephemeris. This data continuously transmitted between satellite and GPS receiver; on the basis of this data we achieve high accuracy.
Accuracy of GPS Devices:
There is a lot of factor in location tracker, it also depend on devices, positions in the sky of satellites effect on high accuracy GPS, You know time is very important and play key role to calculate accurate location, so that is the reason every satellite has atomic clock that save very adhering time. After improvement every point in this world (In range of GPS) focus by four satellites & after confirmation & approved by all four on same point, send signal by one to receivers. Receiver can assess your location in 3 Amplitude 1st is east, 2nd is north and 3rd is altitude. In latest technology also use combination of GPS and Russian satellites for get better courage & accuracy. we already know we require 4 satellite for accurate result but unfortunately if one satellite is not working in area or not in range then you get your location too but it is 2D and may be not accurate because one satellite data is gather by prediction and you got location result approximately but if you in rage of 4 satellite you fetch 3D result and it is accurate as compare to 2D results.
Uses of GPS:
It is totally free for every
company so there is a lot of application made for this
purposes usually it is used in Road Transports, Aviation’s,
Shipping & Railways, Science, and Security guidance applications.
In these days energy is a big problem all over the world most countries have capability to produce energy but problem is it is expensive, then we all need cheap energy recently scientist introduce solar energy it is cheap and only one time investment and gain unlimited benefit. Solar produce cheap energy as compare to fuel and coal energy. This concept of solar energy fetch by mobiles companies and it is use in mobiles charger because after starting android mobile main problem of user is battery charging, then in start mobile companies engineer extra batteries, but it is totally flop idea, then they make power bank market. It is comparatively good idea but they want to thought some in expensive and new technology, then they found solar energy idea and now it is implemented as a new technology.
What's Solar Charger?
It is simple charger working with sun light known as solar charger usually it work for small appliances like mobiles, tablet MP 3/MP 4 players, iPod, games console, cameras, laptop, toothbrush etc... It is not atmosphere friendly because it works with sun lights some countries/areas not have enough sun light, but those countries in which weather are warm mostly or heavy sun light where it work easily or those countries/areas not have enough electricity and they face problem of load-shedding there is solar charger will suitable. Only 1 watt power produce in this charger but batteries make it powerful. In these days solar charge also used in chargeable lights, fans & some small electronic appliances.
How Solar Charger work's?
Now i m going to describe working of solar charger, in which two main component used one is solar panel & 2nd is batteries. 1 Watt panel and batteries depend on charger capacity, there is charger have capability charge 3 mobiles after one charge some have 6 and etc... Just like mobile power bank. Solar panel receives light rays from sun and converts direct in to DC energy and stored in charge connected batteries. This charger solar panel have not enough capability to charge directly to any appliance or mobiles that's way we use batteries and it is also save energy for emergency purpose. If you thought it will not fulfill your need because you have more than one mobile or a lot of usage you will add one more solar panel in same charger it will increase your solar charging capability. Some solar charger have cap ability if there is no sunlight in your areas due to weather or some other problems you will connect it with electricity and charge like normal mobile charger.
Why it is important in future use?
There is lot of benefit of solar charger you will produce cheap electricity by solar panels. Solar panels produce directly DC energy. It will convert easily in Ac energy and engineer also work on this topic even some appliances available in market like solar energy panel for home/office but it is expensive now and quality is not enough good but may be after few month you will purchase best quality solar panel/charger.
On the other hand only major problem estimated by some third party is batteries problem. After 1 year time batteries will dead but it is easily available in market, you will replace it if battery will dead. Purchase solar charger and forget tension of sitting near the electric plug port on the beach or some outing place or in office or any ware in the world and enjoy your life with mobile laptop or other appliances. It is easily available on market/ store or online store.
