We present DAV(3)E, a MATLAB toolbox for feature extraction from, and evaluation of, cyclic sensor data. These kind of data arise from many real-world applications like gas sensors in temperature cycled operation or condition monitoring of hydraulic machines. DAV(3)E enables interactive shape-describing feature extraction from such datasets, which is lacking in current machine learning tools, with subsequent methods to build validated statistical models for the prediction of unknown data. It also provides more sophisticated methods like model hierarchies, exhaustive parameter search, and automatic data fusion, which can all be accessed in the same graphical user interface for a streamlined and efficient workflow, or via command line for more advanced users. New features and visualization methods can be added with minimal MATLAB knowledge through the plug-in system. We describe ideas and concepts implemented in the software, as well as the currently existing modules, and demonstrate its capabilities for one synthetic and two real datasets.

This paper presents a benchmark and accuracy analysis of 3D sensor calibration in a large industrial robot cell. The sensors used were the Kinect v2 which contains both an RGB and an IR camera measuring depth based on the time-of-flight principle. The approach taken was based on a novel procedure combining Aruco visual markers, methods using region of interest and iterative closest point. The calibration of sensors is performed pairwise, exploiting the fact that time-of-flight sensors can have some overlap in the generated point cloud data. For a volume measuring 10m x 14m x 5m a typical accuracy of the generated point cloud data of 5-10cm was achieved using six sensor nodes.

The ferroelectric liquid crystal (FLC) which has the advantage of a fast response under an electrical field has become one of the most promising candidates of the next generation liquid crystal display (LCD) as well as photonic devices. In the display area, sub-millisecond switching is needed to enable field sequential color (FSC) display technology, which improves resolution and efficiency at least by three times when using sequentially coming RGB colors instead of color filters. The FLC allows electrical control of the response time in the range from several microseconds to several seconds. FLC devices also have a great potential in the sensing and detection area since a microsecond response is in high demand for real time sensors. Gratings, optical switches and phase modulators can also be fabricated with FLC, and applied in optical communications, imaging systems, etc. © 2019, John Wiley and Sons Inc. All rights reserved.

In the current oil and gas market, operators are seeking cost-effective and reliable ways to maximize production from existing infrastructures and to improve economics for greenfield applications. Subsea boosting is a technology enabling economically viable subsea tie-backs, life extension of mature fields and increased profitability of new projects. This paper will show how advanced condition monitoring technology can improve operation of boosting systems, thus making this technology more attractive for field operators. In recent years, new sensor technologies have been qualified for subsea use and new platforms for handling large quantities of data have been developed. Aker Solutions has combined these technologies in the development of a novel advanced condition monitoring system for subsea boosting applications. Through use of sensor technology and an integrated software and data analytics platform, it is now possible to operate the pump more efficiently. Increasing the reliability of the boosting system by introducing predictive maintenance planning is a key element in reducing the OPEx and improving the operation of the field. Through execution of an extensive testing campaign in a full-scale multiphase test loop, Aker Solutions has been looking at a number of operating conditions, with varying mixtures of water and gas to demonstrate the performance of this new technology. During the testing, new usage of proximity probes and sensor technologies demonstrated the effectiveness of the system for real-time operation management. This paper outlines the architecture of the system and presents how the hardware improvements, combined with the latest digitalization technologies, can extend the operating envelope of the system and improve availability. © 2018, Offshore Technology conference.

We present a flexible on-board unit (OBU) architecture that provides Vehicle-to-Everything (V2x) communication services. The architecture includes commercial off-the shelf (COTS) hardware components and open source software components. A lambda-like architecture relegates the transfer of full-resolution bulk data over IEEE 802.11 without excluding the ability for high priority short messages to be sent via other means (DSRC, LTE, etc.). In addition to collecting data from the vehicle's sensors, an OBU can collect data from other, visited, sources, e.g., sensor networks operating within range. Bulk data transfers follow a Delay-Tolerant Networking (DTN) paradigm, by exploiting occasional encounters with other peers to perform data exchanges. In this paper, we summarize our experiences in developing such a system.

The popularity of public cloud services continues to grow with Gartner predicting the total worldwide revenue to almost double from $145 billion in 2017 to $278 billion in 2021(1). Many cloud service types are components of this growth including Software-as-a-Service (SAAS), Platform-as-a-Service (PAAS) and Infrastructure-as-a-Service (IAAS). The use of cloud services brings many possible benefits such as scalability, high performance and availability, flexibility, cost effectiveness and security(2). However;each of these benefits comes with some responsibilities and requires a detailed knowledge of the specific cloud services used. For example, in Amazon Web Services (AWS) shared responsibility model for security, AWS is responsible for securing the facilities, physical security of hardware, network infrastructure, and the virtualization infrastructure. The cloud service customer is responsible for securing and managing the applications that run in the cloud, the operating systems, data-at-rest, data-in-transit, policies and other responsibilities. This paper works through several different use cases and provides the details for properly securing the services with which Army Research Laboratory (ARL) researchers interact. The use cases include sample configurations and descriptions required to fulfill the customer security responsibilities in a public cloud environment. Cloud services used include AWS Elastic Computer Cloud (EC2) Windows and Linux instances, Relational Database Services (RDS), Simple Cloud Storage Service (S3), Glacier S3 Storage, and DynamoDB. Challenges and approaches associated with delegating temporary security credentials, Identity and Access Management (IAM) service, and securing data-at-rest and data-in-transit will also be discussed.
