The elements that create the valley of death leads to research and technology development high risk and poor return on investment for a great many research and development organizations. This leads eventually to avoiding research and technology development all together because the organizations cannot viably manage the outcome of their early-stage research and development (ESR&amp;D) efforts. Unfortunately, there are few established frameworks and processes for enabling smooth transitions to avoid failure and manage risk across fundamental research, applied research, development, and productization. Many leaders, program managers, and scientists are unwilling to involve systems engineering because of the perception that systems engineering is heavily process oriented, adds unnecessary costs, and should be applied only to mature technologies. The value of systems engineering as applied to ESR&amp;D is unclear to these key individuals. The unfortunate result is that systems engineering is not applied to ESR&amp;D.

In reality the majority of industry, as opposed to academic, early-stage research and development (ESR&amp;D) efforts are generally not “pure research”, but instead focus on technology development for the purpose of technology transition to applied development and technology insertion into new or existing products. To overcome the barriers, an early and active end-user focused system engineering approach is needed to build the use cases to support the transition from fundamental research to applied development. Digital engineering (DE) enablers can lower the transition investment cost through the use of agile methodologies, reference architectures, and model-based design and manufacturing capabilities.

In using TRLs, it has been observed that bridging the gap between research on a technology and its incorporation by engineers into a system is challenging. Nominally, the transition from TRL 4, defined as a component and/or breadboard validation in a laboratory environment, to TRL 7, defined as a system prototype demonstration in an operational environment, is a programmatic gap known as the “valley of death.” The valley of death is a schism whereby the component that incorporates the new technology fails to meet the eventual system requirements. The goal of this paper is to provide a methodology and “language” that enables the researchers and engineers to communicate more effectively to traverse this gap. The basis for this methodology is the combination of established methods for communicating progress for a program combined with the development and application of domain assessments. Domain readiness levels (DRLs), analogs of the TRLs, are specific to the domains relevant to the system of interest. Specifically, the methodology is intended to enable two-way communication between the domain experts and the systems engineer, with the goal of effective incorporation of a technology. This paper will use an example of the approach to bridge the “valley of death” targeted on the development of a satellite composites optical support structure that must stay in focus across the temperature range of 77-323 degrees Kelvin. In this example, the communication will use two relevant domains, materials and processes, to illustrate the methodology.</p>\u0000 </div>","PeriodicalId":13956,"journal":{"name":"Insight","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50155103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Enhancing Early Systems R&D Capabilities with Systems —Theoretic Process Analysis","authors":"Adam D.

Yet, emphasizing the Aristotelian argument that the “whole is greater than the sum of its parts” seems to offer a conceptual foundation creating new R&amp;D solutions. Invoking systems theoretic concepts of emergence and hierarchy and analytic characteristics of traceability, rigor, and comprehensiveness is potentially beneficial for guiding R&amp;D strategy and development to bridge the gap between theoretical problem spaces and engineering-based solutions. In response, this article describes systems–theoretic process analysis (STPA) as an example of one such approach to aid in early-systems R&amp;D discussions. STPA—a ‘top-down’ process that abstracts real complex system operations into hierarchical control structures, functional control loops, and control actions—uses control loop logic to analyze how control actions (designed for desired system behaviors) may become violated and drive the complex system toward states of higher risk. By analyzing how needed controls are not provided (or out of sequence or stopped too soon) and unneeded controls are provided (or engaged too long), STPA can help early-system R&amp;D discussions by exploring how requirements and desired actions interact to either mitigate or potentially increase states of risk that can lead to unacceptable losses. This article will demonstrate STPA's benefit for early-system R&amp;D strategy and development discussion by describing such diverse use cases as cyber security, nuclear fuel transportation, and US electric grid performance. Together, the traceability, rigor, and comprehensiveness of STPA serve as useful tools for improving R&amp;D strategy and development discussions. Leveraging STPA as well as related systems engineering techniques can be helpful in early R&amp;D planning and strategy development to better triangulate deeper theoretical meaning or evaluate empirical results to better inform systems engineering solutions.</p>\u0000 </div>","PeriodicalId":13956,"journal":{"name":"Insight","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50155104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The examination includes a microfocus X-ray tube and a digital detector array (DDA) with 0.075 mm pixels at three angles of incidence (0°, 5° and 10°). The basis of the methodology for the minimum detectable slit width stems from the noise statistics in the images and a minimum detectable contrast-to-noise ratio (CNR) of 3. These minimum detectable widths range from 0.019 mm to 0.003 mm for 12.8%-deep and 40.0%-deep slits, respectively, for the 0° incidence condition. As the incident angle increases to 10°, the size of the minimum detectable slit width also increases, up to a factor of two for the shallower slits. It is noted that these simulated cracks, which have straight parallel sides and flat bottoms, do not accurately represent natural cracks that have irregular paths and taper at depth. Therefore, the results in this study represent the best scenario for detection, establishing some bounds of crack width detectability.","PeriodicalId":13956,"journal":{"name":"Insight","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135298438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
