About Us

ABOUT

The JSTRE Groups mission is to assist Governments and private organizations having a clear scientific mission. Our experience resides in leveraging technology to support that mission. While not scientists ourselves The JTRE Group has been working with scientists since 2008 primarily in Meteorology, Astrophysics and Aerospace. In short, our mission is to support scientific efforts.

The JSTRE Groups vision is reduce our footprint on engagements in support of the United States Federal Government as we attempt to build International, State and Local engagements. While the current United States Federal Government administration has shown a clear intent to reduce scientific initiatives, we have seen Europe, Asia, Canada and Australia appear to share common goals concerning scientific initiatives and the value of using science to create a better more sustainable world for the future.

About Us

DATA ANALYTICS

Data Analytics experience was obtained during engagements across multiple organizations. While each organization had differing missions our focus on data analytics and supporting activities blossomed when we engaged exclusively with organizations having a core scientific mission.

While data analytic efforts are necessary, having a strong background in software architecture, design and implementation, technical / scientific writing and presentation experience facilitate the success of the efforts.

AEROSPACE

Details

Principal Java developer and solutions architect for MITRE Corporation’s Center for Advanced Aviation System Development (CAASD), the Federal Aviation Administration (FAA), and the aerospace private industry to utilize and make use of software tools to develop statistical mathematical models and reports for dissemination throughout the aviation community. A principal business entity in this arrangement was maintained by the private concern, EUROCONTROL through use of its Base of Aircraft Data (BADA and its Aircraft Performance Model (APM), both complimented by collaboration and active cooperation with aircraft manufacturers and operating airlines. Information and data contained in BADA is designed for use in aircraft trajectory simulations and predictions of which MITRE provided modeling and datasets to support R&D, validation and assessment of new Air Traffic Management (ATM) concepts, Air Traffic Control (ATC) procedures before they are introduced into operational service.

Collaborated with IHS Jane’s Defense Equipment & Technology Solutions to create and establish technical procedures and standards between the two organizations.

Milestone Accomplishments:

Initiated and facilitated on-going meetings with IHS Janes to build a partnership with MITRE CASSD to obtain precise metrics for engineering schematics for British Defense & Security Intelligence & Analysis concern. The effort culminated in MITRE having the capability to MITRE ingest restful Java web service engineering schematics for many aircraft types into the IHS Jane’s Oracle and Hadoop and HFDS data warehouse in order to execute more advanced physics and aerospace equations and define algorithms for the definition and movement of these aircraft.
Co-Authored a research document titled “Validation of Aircraft Performance (APA) Implementation of Base of Aircraft Data (BADA) v.3.7.2” (April 2012). It was an effort by MITRE Corporation’s Center for Advanced Aviation System Development (CAASD), the Federal Aviation Administration (FAA), and the aerospace private industry to utilize and make use of software tools: Aircraft Performance Analysis (APA), JAVA Sector Evaluator (JSE), MITRE Weather Service (MWS), for the purpose of generating fuel consumption and atmospherics metrics used in evaluations of benefits for newly designed procedures and airspace redesign.

  1. These software tools make use of any number of fuel consumption models. One such model is the European Organization for the Safety of Air Navigation’s (EUROCONTROL) Base of Aircraft Data (BADA), the Total-Energy Model (TEM) methodology approach.
In a role as principal technical coordinator defined and developed the software engineering standards and best practices used department wide and conducted demonstrations that lead to those standards being adopted under the auspices of the FAA National Airspace System (NAS) and MITRE Corporation’s Center for Advanced Aviation System Development (CAASD), and the department Analysis of Area Navigation (RNAV) / Required Navigational Performance (RNP). Methods incorporated include standard SDLC staging practices for development and production implementation and the use of JUnit testing framework.  Instituted continuous integration processes utilizing Jenkins, a continuous integration services for software development constructed by the Hudson project at Sun Systems and Maven to perform C.I. builds.   The combination facilitated the continuous integration that supported the viability of the software produced by the department. The result was recognition and institution of those procedures and increased department wide efficiencies in the construction of robust software tools to support numerous research initiatives.
Designed and developed an aircraft performance-modeling software engine that has become the standard modeling engine within MITRE. The software was a principally Java, the software was distributed was the data embedded in the DB4o known as the database for objects and as an embeddable open-source object data store. The benefits are Atomicity, Consistency, Isolation, and Durability (ACID) compliance . It complied with FAA and MITRE project legal standards. The engine was a key component of the Validation of Aircraft Performance (APA) implementation of the Base of Aircraft Data (BADA)
Instituted, designed and developed a big-data proof of concept using Cloudera’s distribution for Apache Hadoop (CDH4). The project combined open-source technologies under the Apache open-source foundation and bundles into a COTS product for MITRE research purposes.
Responsible for documenting the testing methodology, testing results, and the unit-testing framework used in multiple research studies. This led to technical and scientific recognition by the department.

  1. The Unit testing for APA involved defining operations which in aggregate define a higher-order task such as calculations of fuel consumption that involve an operation to calculate the amount of thrust generated by an aircraft. The unit tests were packaged into suites of collections according to functionality.
  2. These functionalities included tests developed to verify the integrity of APA’s infrastructural functionality, which exist to support calculations of thrust, drag, fuel consumption, rates of climb, rates of descent, etc. Functionality checks were also created on the following APA features:
    1. BADA Data Encryption/Decryption
    2. BADA Data Storage Engine Integrity
    3. General Exception Handling
    4. Unit Conversion
  3. Results generated by the unit tests were analyzed in Microsoft Excel and MATLAB.
  4. The developed reporting engine generated web-based reports detailing the success rates of all tests executed. The report listed the total number of tests defined for each package, the number of errors that occurred per test, the number of failures per unit test, the time in seconds for the unit tests to complete, and a column exhibiting the percentage of unit test cases grouped by packages that passed. The test validated the thrust, drag and rates of climb and descent computations, as they are required inputs to the fuel consumption equations. Tests also noted values that were incorrect such as the corresponding derived fuel consumption values.
