MacBook Pro: High Performance at a Price

Innovation has always been a hallmark at Apple.

The new MacBook Pro is no different.

Available soon, Mac fans will find the device has many new features and improvements that should keep this laptop in high demand for both personal and business use.

Start with the design both inside and out. The Pro has an aluminum body, solid state design, and a Core i7 processor. It is more powerful yet thinner and lighter than its predecessors. Try 17% thinner, a significant difference.

Two sizes are available. A smaller 13 inch version weighs in at just three pounds. The 15 inch version weighs just four pounds.

Some fans have been clamoring for a touch screen application from Apple, and the new Pro delivers but in a different way.

Apple has created The Touch Bar. It replaces the function keys that have long occupied the top of the keyboard. This can provide automatic adjustments for system controls like volume and brightness. It provides interactive ways to adjust or browse through content and type with features like emoji and predictive text.

Speed has also been improved. The Pro is said to deliver graphics at a rate 130% faster than before.

The retina display has become an Apple standard and some new enhancements provide colors even more vibrant than before. Brightness is increased by 67 per cent.

Audio is enhanced with totally redesigned speakers. Apple promises 58% more volume and two and a half times more bass. The Pro will enable you to mix a track on the fly, edit video on location, and enjoy a movie as you head to your destination.

For the first time Touch ID is available on a Mac. This enables instant access to logins and fast, secure online purchases with Apple Pay.

The MacBook Pro has a better feel. The keyboard is more comfortable and responsive. The Force Touch Trackpad has been enlarged so your fingers have a little more room to work with.

Those needing extensive business applications will find four USB-C/Thunderbolt 3 ports included on both sized devices.

You will need a new Thunderbolt 3 adapter if you wish to use a hard drive. Once connected, you can integrate data transfer, charging, and video output in a single connector, delivering up to 40 Gbps of throughput for twice the bandwidth of Thunderbolt 2.

The device offers 3.8 GHz with Turbo Boost Processing. Users can expect up to 10 hours of battery life.

And, of course, users will get the MacOS operating system. You can connect with all the Apple apps, iCloud, iPhone 7, Apple Watch and other features.

Prices tend to run to the high-end. They start around $1,500 for the 13 inch model with 256 GB of storage and no Touch Bar or Touch ID. The “Touch” features begin at the mid-level model which runs $1,800. Add more storage to 512 GB and the price hits $2,000.

The 15 inch has similar price elevations. The bare bones model without the Touches runs $2,000. The mid and high-end models with both Touches start at $2,400 for the 256 GB model and hit $2,800 for 512 GBs of storage.

Overall the MacBook Pro has formidable computing power, superb build quality and the long battery life you would expect.

It is an attractive replacement for those seeking a Mac quality high-end desk top in a laptop. Though it comes at a handsome price.

Beware Robots Bearing Beer

The robots are coming… and they’re bringing the beer.

I’ll admit that I don’t think it’s what Philip K. Dick – renowned science-fiction author whose stories spawned such movies as Blade Runner, Total Recall and Minority Report – and Isaac Asimov – think I, Robot and The Bicentennial Man – had in mind, but I do think we are faced with a technology that we can no longer relegate to the realm of science fiction.

Earlier this week, Anheuser-Busch InBev NV and Uber Technologies announced that for the first time ever a self-driving truck completed a commercial delivery. The 18-wheeler truck drove more than 120 miles from Fort Collins to Colorado Springs, hauling Budweiser with the human driver kicked back in the sleeper cab.

While this was just a practice run and there are still more bugs to work out of the software, it remains an important step forward. Anheuser-Busch InBev NV reports that it could save $50 million per year through the deployment of self-driving trucks – even with human drivers riding along – in fuel savings and more frequent deliveries.

This kind of massive cost savings can spread throughout the transportation industry. As a result, this technological development will create some fantastic investment opportunities as companies scramble to implement these types of long-term cost savings.

But there’s also going to be a human cost.

In a bit of great cosmic coincidence, Oxford University and Deloitte released the results of a study earlier this week that revealed 861,000 jobs would be lost to machines in the U.K. public sector by 2030.

While replacing humans with machines will save an estimated £17 billion (US$20.7 billion), we are going to have an overwhelming number of people who are searching for employment and likely surviving on government handouts.

In fact, Deloitte has previously estimated that 74% of jobs in transportation, 54% in wholesale and retail, and 56% in manufacturing are facing the risk of automation.

In September, the transportation industry in the U.S. numbered 1.5 million jobs. That’s a big chunk of jobs in danger. And let’s not forget that America’s manufacturing sector is already shrinking painfully. This economic recovery has seen mostly a swelling of low-paying jobs in sectors such as retail – not a good sign when we’re only going to hand the few jobs we’re gaining over to automation.

This new technology is offering up great investment opportunities for companies in terms of growth and cost savings, but I’m not convinced that it’s going to be creating new jobs as fast as it’s replacing old ones. We’re facing the rise of a dangerous imbalance that could send the global economy toppling over for an extended period of time.

Gas Chromatography Mass Spectrometry Advantages and Disadvantages

Gas Chromatography Mass Spectrometry (GC-MS) combine two powerful techniques in order to provide the identification of compounds that have low detection limits and potential required for quantitative analysis. Gas Chromatography Mass Spectrometry analyses works on liquids, solid and gaseous samples but are primarily restricted to semi volatile and volatile compounds.

Under Gas Chromatography, a sample is carried and volatilized and carried by the inter gases through a coated glass Capillary Column. The stationary phase is joined to the interior of the column and the amount of time it takes a specific compound of an element to pass through this column on to a detector is called its “Retention Time”. These measurements are used for identification purpose when compared to references.

Under usual Mass Spectrometry or MS step under the Gas Chromatography Mass Spectrometry, the compounds leaving the GC columns are fragmented by the electron impact. These charged fragments are detected gradually and the subsequent spectrum obtained is used to identify the molecules. Fragmentation patterns are reproducible and thus, can be used to create quantitative measurements.

Gas Chromatography Mass Spectrometry analysis is performed on gases, solids and liquids. For gases and liquids, the samples are usually injected directly into the Gas Chromatogram. For the solid elements, the analysis is carried our through outgrassing or desorption, solvent extraction or pyrolysis. Desorption experiment is performed under the flow of helium gas at controlled temperature ranging between 40 to 300 degree Celsius. The analytes are then collected on a Cryogenic trap during desorption process. The sample chamber is a 1.25″x4″ cylinder.

Pyrolysis is yet another sampling technique used for the analysis of materials that are impossible to be directly injected into Gas Chromatography Mass Spectrometry. Under this process, heat is directly applied to the sample that results in breaking down of the molecules in a reproducible way. These smaller molecules are then introduced in the Gas Chromatogram and analyzed by the GC-MS. By this method, probe temperatures of up to 1400ºC can be used.

Several other sampling methods and sample preparation are available such as static headspace analysis, derivatization, purge and trap, Solid Phase Microextraction etc. having applications based on species of interests and sample types.

Strengths

  • Identification of organic components through separating complex mixtures
  • Quantitative analysis
  • Trace determination of organic contamination (low to mid-ppb level for liquid matrices and low nanogram level for solid matrices?

Ideal Uses

  • Identifying and quantifying volatile organic compounds in mixtures
  • Outgassing studies
  • Testing for residual solvents
  • Evaluating contaminants on semiconductor wafers or other technology products (thermal desorption)
  • Identifying trace impurities in liquids or gases

Limitations of Gas Chromatography Mass Spectrometry

  • Non-volatile matrices (wafers, metal parts oil, etc.) require additional prep (extraction, outgassing, etc.)
  • Evaluating extracts from plastics
  • Target compounds must either be volatile or capable of derivatization
  • Atmospheric gases are challenging (CO2, N2, O2, Ar, CO, H2O)

Advantages

GC MS has long been considered to be the Gold Standard for all sorts of analytical laboratories. It is a strong analytical tool that uses time for the chemical elements to travel through the GC column, the retention time as compared to known standards to identify the chemical. It is a good technique for simple mixtures and for situations where the chemicals of concern are known and calibrated before running samples. Though there are advantages and disadvantages of all the process but together these factors are helpful in evolution and advancement of laboratory processes and identification of elements.

Drones, AI and Big Data Transforming the Warfare Future

The warfare techniques have undergone a complete makeover ever since the entry of Big Data and IoT (Internet Of Things) in this industry. It has enhanced not in just the way opponents engage in a war but also the fronts on which they get engaged, though the dilemma of its usage is still debatable.

Taranis is an autonomous stealth drones by BAE Systems. It is named after the Celtic God of Thunder. This drone when programmed with a flight path in a pre-selected area can fly, identify threat, target it and send an alert to the human operator. The human operator reviews and then approves if required for the attack. Taranis then fires and destroy the target threat with a missile and flies back home.

As of today military widely uses drones for conducting surveillance, attack hostile target, spot submarines and mines. With advantages like being smaller and stealthier these drones have been also found successful in delivering humanitarian aid to distant places. As it is distantly controlled the safety of the pilot is also enhanced.

Though this fact doesn’t thrill many people, owing to the possibility of killing, damaging or destroying autonomously. A huge list of people have written an open letter to UN (United Nations) to crease the use of these weapons as it’s not clear how and where human intervention or approval is sought by the machine. The human intellect can’t be fully replaced by these machines.

Another factor that challenges the weapon equipped with AI, Big Data, IoT is that battle fields and line of controls can be replaced by digital networks replacing soldiers with hackers. If the attack is done on the network itself these weapons can turn highly suicidal. Making things smart are making them venerable too.

These facts can be over- sided by organizations like the Defence Department of United States, the UN, and the CIA. These organisations in last few years have launched many initiatives using these weapons to anticipate outbreaks of diseases, crisis (political, economic & natural) and shortage of resources.

The organisations like these and many more are able to gather huge unstructured data from various sources like reports from media, blog and social media posts using these technology. This data was then used to anticipate and plan events/intervention as well assesses which actions were successful, though it will take time to enhance the scale of impact of these technologies.

Using this data to prevent problems and promote peace may still be a long way off, but because these are learning algorithms, every bit of data they receive and every prediction they make brings them closer to their goals.
