Julia Lang - Enabling Mathematical Modeling

 In 2016, I started using Julia Lang based on its open source availability and the extensive published conference videos posted on YouTube.  I liked Julia for several reasons: (1) linking to C, C++, FORTRAN, Python libraries, (2) GPU interface support, (3) REPL, (4) parallel compute interfaces and (5) differential equations. Differential equations are at the core of most domains, enabling compact mathematical equations relating subsystems to each other.  There are many programming language utilized for a variety of tasks including web services, databases, operating systems, distributed systems, file systems, etc. There are very few programming languages dedicated to ease scientific and engineering modeling and exploration. With ease means that first level programming entities such as matrices and vectors. Famous proprietary examples include Mathematica,  Macsyma, Matlab. Julia provides a shareable, non-proprietary implementation: https://juliapackages.com/p/diffeqtut...

QEEG - Quantative EEG - 3-sigma reliable mental health diagnostic fda-approved method; original patent in public domain

High Level Summary  QEEG practitioners indicate medical assessment: QEEG Normative DB  - QEEG Technical Paper  -  Brain Center - University of Houston  ; U of Washington    UW2   UW3 Software -  Commercial - Thatcher  - Biof Open Source - EEGLAB  , S-LORETA 1) QEEG as practiced by a psychiatrist enables objective means to determine drug and dosage; as opposed to current practice of prescribing random drugs based on marketing claims with no means to check for objective improvements. 2) QEEG as practiced for assessment of TBI or mTBI is more accurate than MRI; brain can swell up to two days after incident.  MRI's are often taken just after an head injury incident; EEG changes after 20 minutes of incident. In military TBI, the IED blast injures the closest personnel.  The question is how to determine if the concussive force affected others within the team in a field environment ?  Fortunately, portable EEG devices with Q...

Memex and what it all means ...

memex-1 Memex conceptually cross-links all data into single compressed graph of indexes. Searches against the Memex can be as simple as a keyword search or as complex as an entire article about a domain an entire numerical vector representing on IOT sensor stream combination of an analysis article and numerical vector representing on IOT sensor stream combinations of sets of analysis articles and set of numerical vector representing all IOT sensors associated with an event, a route or a recipe With the expectations that the search would return similar articles, similar numerical vectors, similar sets of articles and numerical vectors or combinations thereof, ordered by similarity.  A  natural query format is supported as if the Memex is like an entire set of enterprise experts whereby another person could query simply with a few keywords or specifically what is similar to an actual textual description contained in an email or other document. The API is not like RDF or SPARQL o...
