What is a precision balance or laboratory balance?
Precision laboratory balances, also called top-loading balances, are a form of balance that provides very precise results in the sub-milligram range. Precision balances are used to measure small samples and provide a precise, quick and easy way to determine the weight of objects such as particles.
 
Electronic precision scales offer a wide range of weighing ranges with a maximum capacity of 64 kg. They allow readability between 1 mg (0.001 g) and 1 g or 0-3 decimal places. High precision laboratory balances can extend this precision to 4 decimal places. When viewing the Precisa balance price, increments of 0.0001 g (0.1 mg) are used.
 
Precision balances provide constant readings in a wider range of environmental conditions than analytical balances, which must always be used under rigorous conditions to ensure accurate readings. Precision balances are less sensitive to temperature changes and drafts and can, therefore, be used as a more practical measurement method.
 
A draft shield is not always required to accurately use a precision balance, but when working in a range hood or under normal conditions with a high-resolution reading of 1 mg, A should be used to maintain performance.
 
The innovative SmartPan ™ weighing pan, used by the precision balances of the data support company XPR and XSR, offers exceptional stability and significantly reduces the impact of drafts on results.
 
Repeatability has improved by up to 50% and even with 1 mg precision balances, precise results can be obtained without protection from drafts.
 
When used in a smoke chamber, the 5 and 10 mg models dispense only half of the standard models.

Where are the precision balances used? What are the fields of application of precision balances?

A large number of industrial sectors depend on the accuracy of the scales. Chemistry most often gives exact results.
 
For a balanced level of precision, from research and quality control laboratories in the pharmaceutical, chemical, food and textile industries to educational institutions.
 
Applications of a precision balance in a laboratory environment include simple weighing, dynamic weighing, sample preparation, statistical quality control, formulation and interval weighing.
 
A reliable and high precision balance is the ideal choice for any daily laboratory weighing.
 
High precision laboratory balances with a load capacity of 10 kg or more and a larger platform are generally used in applications for aggregates, pharmaceuticals, chemicals, and adhesives.

Calibration, adjustment and routine testing of a precision balance: who should do what, when and why?

A precision balance calibration evaluates the behavior of the selected instrument. Calibration should only be performed by an authorized service technician.
 
An adjustment changes the behavior of a scale and requires an intervention which, in most cases, permanently changes the measuring device.
 
The adjustment must not be confused with the calibration, the terms are not interchangeable and the calibrations must always be performed on the scale after each adjustment. In many cases, they are in fact the results of a calibration procedure that indicates the need for adjustments or other repairs.
 
After completing the adjustment or repair, always repeat the calibration process to ensure that the correct measurement report has been restored.
 
Of the calibrations performed by a technician, routine user tests should also be performed with two external weights.
 
These user tests allow you to immediately identify potential problems and deviations from the weighing process requirements.
 
The data support company has developed a worldwide scientific standard for the correct selection, calibration, and operation of weighing technology, known as GWP® or Good Weighing Practice ™.
 
Further information on the terms of calibration and balance adjustment can be found in the document.

What influence do drafts have on my precision balance?

As mentioned earlier, precision electronic scales do not measure mass directly, but the strength of their weight.
 
The uncertainty of this force depends not only on the technical data of the measuring device but also on many environmental influences, such as changes in temperature and air currents.
 
With measurements of 0.001 g or less, the force exerted by the moving air is easily recognizable. A protective screen or cover, usually made of plastic or glass, fits around the plate to protect it from these influences.
 
The latest innovations in data carriers in the construction of scales and precision scales help to minimize errors caused by drafts.
 
With the innovative SmartPan ™ weighing pan, you can achieve twice as fast results, even in difficult conditions.
 
The results show an exceptional improvement in repeatability (accuracy) of 86% with a readability of 1 mg in difficult conditions (inside a safety cabinet) and offer exceptional performance for each application.

How does temperature affect my precision balance?

Temperature fluctuations can lead to illegible weighing results.
 
For optimum stability and performance of the measuring instruments, the scales should be used in an area where the room temperature can be regulated and in which the instrument must remain on at all times.
 
The balance should ideally be installed in a dedicated workbench with an adequate and maintained ambient temperature.
 
When a precision balance is first connected to the power source or turned on, a warm-up time of approximately 1 to 2 hours is recommended. This time allows the scale to adapt to the ambient temperature and stabilize in its environment. This heating phase must be repeated every time the balance is turned on after a period of inactivity.
 
The precision scales of the data support company are equipped with “FACT” (fully automatic motorized internal self-regulation), which compensates for temperature variations.
 
If a defined temperature difference is exceeded, the configuration process starts automatically. This guarantees the accuracy of the scale without operator intervention and guarantees better usability in all applications.

Top 3 Self Driving Car Companies to Watch out in 2020

Many organizations are working on developing self-driving cars and hardware for autonomous cars of all types.

In this race to build a completely self-driving car, some companies are further in terms of real-world testing and practical experience than others.

We will have a look at all the top 3 self-driving car companies in the world.

Top 3 Autonomous Vehicle Companies 

1.Waymo

On the basis of the number of vehicles testing and the number of kilometers driven, Waymo tops the list with over 32 million kilometers driven on the road.

Their cars are equipped with advanced cameras, LiDAR, and radar sensors along with a microphone that detects sirens from emergency vehicles

Currently, Waymo is testing is the prototype of fully driverless SAE Autonomy Level 4 vehicles in Phoenix and Arizona.

Waymo has recently set up additional testing facilities in Michigan and California to test its cars in winter conditions.

The next on the list is Tesla.

2.Tesla

Tesla is putting enormous efforts to develop a fully autonomous vehicle.

Although Tesla has excluded the Light Detection and Ranging(LIDAR), Tesla instead prefers ultrasonic, radar, and 2D cameras for autonomous operations.

The company has till now collected data from 600,000 Tesla’s with having collectively driven more than 3.2 billion kilometers world-wide.

One can’t deny the fact that Tesla has built up a level of experience with some auto-pilot features of SAE level 2.

Reports state that their prototyping vehicles have already reached SAE level 5.

3.ARGO AI

Argo AI is an independent startup that started in 2017, with a $1 billion investment from Ford Motor Company. The company has also attracted a $2.6 billion investment from Volkswagen.

Argo AI today is testing over 100 vehicles in almost 6 cities of the United States.
Technically it’s still an independent venture. Unlike other manufacturers, AgroAi doesn’t foresee producing its own cars. Rather Ford and VW want Argo AI to manufacture self-driving car technology for other companies starting with service-based firms like the Robo-taxis.

There are quite few other companies that are promisingly working on developing a self-driving car like the ones Baidu and GM cruise developed.

Even startups like Cruise Automation, Tu Simple, and Zoox are working towards developing AI  for autonomous vehicles. E-learning platforms like Udacity has already launched their courses on self-driving cars that teach how to make one.

While completely autonomous vehicles won’t become mainstream in the next few years, Waymo, Tesla, and Argo AI are making significant advances in the self-driving car market.

With improvements in IoT technologies, strides toward fully autonomous vehicles are sure to follow.

As IoT technology continues to improve, strides toward fully autonomous vehicles are sure to follow.

[Solved]Mac Starts to Prohibitory Symbol After macosBig Sur Update

macOS Big Sur will be the next version of Mac OS, announced at WWDC 2020. It is again named after the landscape in California but skips the macOS 10 version to macOS 11. According to the macOS Big Sur preview from Apple, the new features mainly sit in the new control center, interface and notification center as well as improved apps such as Safari, Messages and Maps.

However, the new OS doesn’t always bring good news. Here is a list of macOS 11 known issues and fixes. In this article, we will specifically discuss the Mac booting into a prohibitory symbol on the screen after macOS Big Sur update.

What does it mean when your Mac boots to a prohibitory symbol?

When a circle with a line cross it appears on your Mac’s monitor instead of a login screen or desktop, it is very likely that your Mac doesn’t support running macOS Big Sur. Even though the OS can be successfully downloaded on the startup disk, the relevant hardware is unable to install the OS nor launch it for use. It is a very typical problem people encounter when they update their Mac computers.

What Macs are compatible with macOS 11 Big Sur?

It is recommended to check the system requirements before you upgrade your Mac, especially before a major OS version upgrade. Some models can run macOS Catalina but are not necessarily compatible with macOS Big Sur.

macOS 11 Big Sur can be running on Macs including:

  • MacBook models from early 2015 or later
  • MacBook Air/Pro models from 2013 or later
  • Mac mini models from 2014 or later
  • Mac Pro models from 2013 or later
  • iMac models from 2014 or later
  • iMac Pro models

By checking the Mac’s hardware information, you can go to Apple logo and About This Mac to know your Mac model.

How to fix the prohibitory problem issue?

Now you know macOS Big Sur is not the right OS to run on your Mac, but how to get rid of the downloaded macOS 11 files and restore the Mac? Don’t panic. The steps are very easy.

Step 1: Boot your Mac into Recovery Mode.

You need to start or restart your Mac and immediately press down Command, Option and R keys together. Release the keys until you see a loading screen. The booting process will be a lot slower than usual. Then you will be led to the OS X Utilities or macOS Utilities window.

Step 2: Back up files from the Mac.

If you are afraid of data loss, you can use Target Disk Mode or data recovery software to get the important files off the Mac first.

Step 3: Reinstall OS

You can choose to format the hard drive first in Disk Utility and reinstall OS. Also, you can directly reinstall OS by selecting Reinstall OS X or macOS and clicking Continue. You just need to follow the wizard to finish the reinstallation.

Conclusion

Before you update to a newer OS, do remember to check the compatibility first in case you will boot to a prohibitory symbol during the installation. If the issue is happening, you can easily restore the Mac to a bootable state. macOS 11 Big Sur is a beta now and will be released to public in fall 2020, so it is recommended to upgrade after it is officially released if your Mac is compatible.

7 Advantages Of A Dedicated Server
  1. Improved Reliability and Control

Many organizations looking for superior reliability and seamless company operations often go for nothing less than a dedicated server.  This is because dedicated servers offer unmatched reliability with all the server resources dedicated to the company tasks and workload. This means employees can work on internal applications seamlessly while customers access specific apps without facing any downtimes. Such is critical for companies working on mission-critical applications.

  1. Backup Servers

While disruptions may be inevitable in the modern world, most companies will want to keep them on the minimum.  You, however, need to have safety and backup measures in place should the worst happen.  This is particularly in the case of a power outage, floods, and a security incident, among other incidences.  However, a dedicated server makes it possible to set up an off-site backup system where all data is backed up immediately and efficiently. This means you get operations back up and running within the shortest time possible, hence minimal disruptions. Such reliability and resilience are only possible with a dedicated backup server.

  1. High-Volume And Web Traffic Servers

A dedicated server is your best solution for websites and apps looking to handle tons of traffic at one go. These servers are designed to handle web-based workloads with heavy spikes, periodic, and on-demand loads that might be too much for a cloud-based server. Only a dedicated server can guarantee you of continued availability, uptime, and resources even when traffic is at its peak. That said, it would be wise to pay a little more for the peace of mind and guarantee that everything will be working optimally.

  1. SaaS Applications

Companies dealing with software-as-a-service and B2B applications get better support on dedicated servers as compared to other types of servers available today.  In addition to its unrivaled performance and uptime, a dedicated server offers total control over its resources. This guarantees the SaaS users of optimal performance with little to no downtimes.

  1. Video Streaming And Conferencing

With more and more companies/organizations adopting a unified form of communications, many are switching to communications-as-a-service. This service makes it easier for employees and staff to hold video conferences from various departments.  However, only a dedicated server is capable of handling and providing the bandwidth required to offer such a service. Video streaming and conferencing can be a little too demanding on shared server resources; another reason a dedicated server is better designed to handle such heavy loads.

  1. I/O Intensive Databases And Big Databases

Most applications and processes built on big I/O databases, including Microsoft SQL, Oracle, and MySQL, require a server with unlimited resources to perform optimally.  Only a dedicated server is presumably capable of handling such intensive input/output databases and big data.  With big data, and especially IoT (internet of things) on the rise, and streaming data running on continual calculations, more and more companies are looking for more control in the form of customizable software/configurations to suit their workloads. Only a dedicated server offers such versatility.

  1. Sensitive Data On Highly-Regulated Industries

While cloud security has improved on public domains and especially on shared cloud resources, most organizations find it almost impossible to operate under such. One of the reasons for this is the fact that the organization can only run only on a dedicated server, and nothing less. It thus would have to comply with such requirements to be able to operate.

With numerous risks arising from running on a cloud/shared hosting server, most organizations aren’t willing to take such risks. Some of the most commonly known issues associated with shared resources include data leaks and access configuration errors, most of which are too costly for many organizations.  On the other hand, a dedicated server provides your trusted support staff and team members with all access privileges, with the organization required to ensure optimal information security.
