Augmented intelligence

System and Method for Augmenting Healthcare Provider Performance

Abstract
A system and method for augmenting healthcare-provider performance employs a head-mounted computing device that includes camera and microphones to capture a patient encounter and events immediately before and after: video, dictation and dialog. Wearing the device by the provider during the encounter permits normal interaction between provider and patient, encouraging the provider to maintain focus on the patient. An “ears-open” earpiece delivers audio data from a remote location without obstructing the ear canal. Augmented reality multimedia is displayed via a heads-up display over the eye(s). Real-time capture of audio and video enables dramatic cost reductions by saving doctor time. Using the system, a doctor no longer need spend hours daily on transcription and EHR entry. A patient encounter is captured and transmitted to a remote station. Relevant parts of the encounter are saved or streamed, and updates to an EHR are entered for provider confirmation after the patient encounter.

Augmenting a business intelligence report with a search result

Abstract
A computer augments a business intelligence report. The computer populates a business intelligence report with business data imported from business data storage, and with a stored internet search query. The computer causes the display of the business data of the business intelligence report. The computer also transmits one or both of a term of the stored internet search query or of referenced business data of the stored internet search query to a designated search engine, and receives a contemporary search result from the designated search engine. The computer causes the display of the contemporary search result.

Magnesium and Its Alloys - Increasing Use in Products

Magnesium (Mg)  is  an  alkaline  earth  metal  having  atomic  number 12  with oxidation  number +2.

Density at 20°C (g/cm3) Magnesum 1.74 Aluminium  2.70 Iron 7.86


The cost of magnesium has been decreasing below the cost of the  aluminium since 2004. M
agnesium  melting  cost  is  2/3  compared  to  aluminium. In terms of productivity, magnesium provides    25%  higher  casting  productivity  compared  to  aluminium  pressure  die  casting,  300-  500% compared  to  aluminium  permanent  mold  casting,  and  200%  compared  to  polymer  injection molding.

Magnesium is considered to be a good choice material in the areas of defense and aerospace engineering for aircraft and missile components,  aircraft engine mounts,  control  hinges,  fuel  tanks,  wings.  In  automotive  sector  magnesium  is  used  for  wheels, housings, transmission cases, engine blocks, steering wheels and columns, seat  frames,  electronic goods  like  laptops,  televisions,  cell  phones  and  in  many  more  areas  (http://www.intlmag.org/).



ASTM  (American Society for Testing and Materials)  names the Magnesium alloys with two letters
defining  the  elements,  with  numbers  denoting  the  percentage  and  an  additional  digit  to indicate intermediate properties.


An ASTM code for magnesium’s alloying elements

Letter  Alloying Element     Letter  Alloying Element
A  Aluminum                      L  Lithium
B  Bismuth                         M  Manganese
C  Copper                           N  Nickel
D  Cadmium                       P  Lead
E  Rare Earths                    Q  Silver
F  Iron                                 R  Chromium
H  Thorium                         S  Silicon
Z  Zinc

For example, AZ 91 Mg alloy contain  aluminum  (Al) and  zinc (Zn) in 9%, 1% respectively in total and the rest by pure magnesium.

Interviewed engineering graduates for four days during 28 to 31 March 2017. They do not know the usage of magnesium in mechanical engineering product components.


2016

Global demand for magnesium metal will reach 1,085 KT in 2016, representing market value worth US$ 3.13 Bn.
Magnesium’s applications in making automotive wheels, transmission cases, and engine blocks will continue to fuel demand in 2016 and beyond.
Application-wise, magnesium alloys and die-casting will continue to remain the largest segments, accounting for 349 KT and 302 KT respectively in 2016.
Magnesium will continue to witness stable demand from the aerospace sector, owing to its excellent properties as a reductant in manufacturing titanium.
The global magnesium metal market is anticipated to increase at a CAGR of 7.1% during 2016-2026, reaching 6.2 Bn in revenues by 2026.

Magnesium alloys are very attractive for a range of weight-sensitive applications. They have the largest strength-to-weight ratio of the common structural metals, are lighter than aluminum and are particularly favored for being easy to machine and for their ability to be die cast to net shape. Unfortunately, magnesium alloys tend to corrode too easily. A team at Monash University in Australia has now discovered a novel and potentially game-changing approach to the problem: poisoning the chemical reactions leading to corrosion of magnesium alloys by adding a dash of arsenic to the recipe.

Magnesium alloys are of great interest as lightweight replacements for aluminum, titanium, and steel components in a range of transportation and aerospace applications. However, magnesium alloys corrode easily, and this often prevents their use as substitute for noncorroding metals.  As a result, the use of magnesium alloys at present is less than a million tons per year, while nearly 50 million tons of aluminum alloys are used each year. The experimental demonstration of reduction in corrosion of magnesium is a welcome step.  The result was that addition of about one-third of a percent of arsenic to the magnesium alloy reduced its corrosion rate in a salt solution by a factor of nearly ten. In this initial study the intent was to prove the principle of the use of cathodic poisoning to reduce corrosion of Magnesium.
