ABSTRACT The Integrated Systems Engineering Framework (ISEF) is an Army Research, Development, and Engineering Command (RDECOM) solution to address stovepiped systems engineering(SE) information and processes, disparate tools united by custom, one-off integrations, and a lack of accepted, common standards that exists in today’s Department of Defense (DoD) operating environment. Ever increasing technical complexity of fielded solutions combined with budgetary constraints push DoD engineers to “do more with less,” requiring a technical management solution that allows them collaborate virtually yet effectively with distributed engineers and other stakeholders. Easy access to systems engineering tools and information through a single “cloud” based application allows connections between federated databases, and facilitates knowledge preservation over time to avoid “reinventing the wheel” when new programs replace retired ones. ISEF is an ever-expanding collection of systems engineering
ABSTRACT The proliferation of information technology adds expanded capabilities and exposes new vulnerabilities through cyber warfare. To combat new threats software quality must go beyond CMMI maturity levels and embrace a software development lifecycle (SDLC) with measurable cybersecurity assurance. Standard cybersecurity artifacts throughout the SDLC should be expected and available for inspection. Integrated software applications can confidently and rapidly reduce their threat exposure by incorporating reusable data management components with a pedigree of cybersecurity SDLC assurance evidence

ABSTRACT Geotechnical site characterization is the process of collecting geophysical and geospatial characteristics about the surface and subsurface to create a 3-dimensional (3D) model. Current Robot Operating System (ROS) world models are designed primarily for navigation in unknown environments; however, they do not store the geotechnical characteristics requisite for environmental assessment, archaeology, construction engineering, or disaster response. The automotive industry is researching High Definition (HD) Maps, which contain more information and are currently being used by autonomous vehicles for ground truth localization, but they are static and primarily used for navigation in highly regulated infrastructure. Modern site characterization and HD mapping methods involve survey engineers working on-site followed by lengthy post processing. This research addresses the shortcomings for current world models and site characterization by introducing Site Model Geospatial System
ABSTRACT The growing sophistication and emergence of widespread cyber threats today has driven the DOD to place Cyber Resiliency requirements on new and legacy defense systems. The DOD has recently garnered a massive defensive DevSecOps effort aimed at defining structured practices to unify software (Dev), Security (Sec), and operations (Ops) under the umbrella of more OpSec-driven engineering practices. According to the DOD DevSecOps practicum referenced in this document [1], “Practicing DevSecOps provides demonstrable quality and security improvements over the traditional software lifecycle, enabling application security, secure deployments, and secure operations in close alignment with mission objectives.” Modern systems often contain greater networking capability and are therefore more exposed to cyber-threats. Legacy systems were often conceived prior to the field of cyber warfare maturing, resulting in unpatched potential vulnerabilities that could be exploited through trusting

ABSTRACT The complex future battlefield will require the ability for quick identification of threats in chaotic environments followed by decisive and accurate threat mitigation by lethal force or countermeasure. Integration and synchronization of high bandwidth sensor capabilities into military vehicles is essential to identifying and mitigating the full range of threats. High bandwidth sensors including Radar, Lidar, and electro-optical sensors provide real-time information for active protection systems, advanced lethality capabilities, situational understanding and automation. The raw sensor data from Radar systems can exceed 10 gigabytes per second and high definition video is currently at 4 gigabytes per second with increased resolution standards emerging. The processing and memory management of the real time sensor data assimilated with terrain maps and external communication information requires a high performance electronic architecture with integrated data management. GDLS has
Abstract New technological advancements call for innovative cybersecurity assurance measures in preventing increased vulnerabilities through cyber-attacks and cyber warfare. Current encryption processes are no longer failsafe in secure data management architectures, especially with accessibility to Advanced Encryption Algorithms (AES). Through new technological advancements, including informational technology architectures and autonomous vehicle implementation, it is imperative to provide new paradigms of security against cybersecurity breaches. In all realms of data usage, including the development of the Next Generation of military vehicles, the demand for significant preventative measures in cybersecurity assurance has dramatically increased. The matter of advanced need in cybersecurity can be established through the use of MicroToken Exchange™ (MTE). By way of MicroToken Exchange, it is possible to provide an additional robust layer of security that allows the right data, as well

ABSTRACT The value of modularity in ground vehicles to the Army and other services has been a topic of much debate for decades. There are instances of successful implementations of modularity in current ground vehicle programs of record. However, these implementations have generally been accomplished through swappable mission equipment rather than large-scale transformation of the vehicle and its core components. Concurrently, the Army Science and Technology (S&T) community has continued to demonstrate the technical feasibility of large-scale, transformative ground vehicle modularity, but the business case of modularity remains elusive. Decision support tools are needed to enable Army leadership to confidently and holistically assess the right balance between modular and mission-specific (conventional) vehicle platforms. This complex problem needs to address numerous considerations, including total lifecycle cost, mission utility, personnel requirements, and fleet adaptability. In this
ABSTRACT The Advanced Systems Engineering Capability (ASEC) developed by TARDEC Systems Engineering & Integration (SE&I) group is an integrated Systems Engineering (SE) knowledge creation and capture framework built on a decision centric method, high quality data visualizations, intuitive navigation and systems information management that enable continuous data traceability, real time collaboration and knowledge pattern leverage to support the entire system lifecycle. The ASEC framework has evolved significantly over the past year. New tools have been added for capturing lessons learned from warfighter experiences in theater and for analyzing and validating the needs of ground domains platforms/systems. These stakeholder needs analysis tools may be used to refine the ground domain capability model (functional decomposition) and to help identify opportunities for common solutions across platforms. On-going development of ASEC will migrate all tools to a single virtual desktop to promote

Neurostimulators, also known as brain pacemakers, send electrical impulses to specific areas of the brain via special electrodes. It is estimated that some 200,000 people worldwide are now benefiting from this technology, including those who suffer from Parkinson’s disease or from pathological muscle spasms. According to Mehmet Fatih Yanik, professor of neurotechnology at ETH Zurich, further research will greatly expand the potential applications: instead of using them exclusively to stimulate the brain, the electrodes can also be used to precisely record brain activity and analyze it for anomalies associated with neurological or psychiatric disorders. In a second step, it would be conceivable in future to treat these anomalies and disorders using electrical impulses
