A Multi Platform for Utility using open FMBTM Reference Architecture: Chalenges and Lessons Learned

The exponential growth of smart micro grids is making centralized control unmanageable. Data generated by grid-edge devices are also inaccessible due to the installation of private micro grids with proprietary communication protocols. The OpenFMBTM reference architecture solves this interoperability issue and eases the manageability of huge data by creating a virtual node that would allow exchange information between field devices with the use of publish/subscribe paradigm. However, the OpenFMBTM framework is yet to be adopted by industries but researches related to the implementation of this framework is being conducted with the aim to find out the cost and reliability on performance issues such as accuracy, scalability and security. Smart Grid Interoperability Panel (SGIP) provided a live demonstration of OpenFMBTM framework at DistribuTECH conference. DistribuTECH demo provides a guideline to setup simulators deployed in a single Linux machine. This paper discusses about the simulation demo and lessons learned to further developing the project. The implemented demo focuses on the use of MQTT communication protocol for transport layer data transfer. The experiment uses the guidelines of the DistribuTECH demo and addresses the challenge of deploying the framework in real devices at industry level.

Distillate Fuel

California experienced a 300% increase in loss of propulsion (LOP) incidents since its distillate fuel regulation came into effect in 2009. The compression ignition (Diesel) engines aboard modern cargo ships over 10,000 gross tons use 3.0% sulfur Heavy Fuel Oil (HFO). This fuel must be heated to flow through the fuel lines because at normal ambient temperature HFO has the consistency of tar. Distillate fuel in contrast does not require the high temperatures, and the thermodynamics of cooling metal, gaskets and seals resulted in leaks, along with filter clogging from engine buildup scrubbing. In addition, the cost savings of using HFO are significant over the use of distillate fuel which is typically around US$300 more per ton.

In February 2013, in the 2005 built 15500 TEU 397m long container ship EMMA MÆRSK a severe leakage occurred in as it was passing southbound through the Suez Canal. The leakage occurred due to mechanical breakdown of a stern thruster causing flooding of the shaft tunnel and filling up the engine room with 14000 m³ of seawater within a span of two hours, submerging the main engine cylinder heads-level equal to the outside water draft of 15.1 m. The cost of repairs and loss of revenue for six months amounted to a few million dollars. This paper highlights some of the lessons learned from this incident.

Alloy Systems

Advanced manufacturing processes improve the cost and quality of goods. Rotary friction welding is a fast, energy-efficient, and reliable joining process for metals, but new applications are hindered by large development costs for each new alloy. Each alloy set has different welding characteristics; therefore, lessons learned from a single alloy are not always broadly applicable. To establish knowledge that is applicable across multiple alloys, a family of different superalloys were welded to discover process trends that were applicable beyond a single alloy set. In this study, weld symmetry did not correlate to weld strength across alloy systems. Some alloys’ strongest welds occurred at maximum symmetry, whereas high asymmetry was associated with different alloys’ maximum strength. High feed rates, high welding forces, low energy, and low temperatures all resulted in high-strength welds across all alloy and geometry combinations. Tensile strengths greater than 95% of base-metal strength were recorded for most alloy systems.

The Cost

The accurate knowledge of Heat Transfer Coefficients is essential for the design of precise heat transfer operations. The determination of these values requires Inverse Heat Transfer Calculations, which are usually based on heuristic optimisation techniques, like Genetic Algorithms or Particle Swarm Optimisation. The main bottleneck of these heuristics is the high computational demand of the cost function calculation, which is usually based on heat transfer simulations producing the thermal history of the workpiece at given locations. This Direct Heat Transfer Calculation is a well parallelisable process, making it feasible to implement an efficient GPU kernel for this purpose. This paper presents a novel step forward: based on the special requirements of the heuristics solving the inverse problem (executing hundreds of simulations in a parallel fashion at the end of each iteration), it is possible to gain a higher level of parallelism using multiple graphics accelerators. The results show that this implementation (running on 4 GPUs) is about 120 times faster than a traditional CPU implementation using 20 cores. The latest developments of the GPU-based High Power Computations area were also analysed, like the new NVLink connection between the host and the devices, which tries to solve the long time existing data transfer handicap of GPU programming.

The Cost

Summary Interest is high in a method to reliably run single-trip completions without involving complex/expensive technologies (Robertson et al. 2019). The reward for such a design would be reduced rig time, safety risks, and completion costs. As described herein, a unique pressure-activated sliding side door (PSSD) valve was developed and field tested to open without intervention after completion is circulated to total depth (TD) and a liner hanger and openhole isolation packers are set. A field-provensliding-sleeve door (SSD) valve that required shifting via a shifting tool run on coiled tubing, slickline (SL), or wireline was upgraded to open automatically after relieving tubing pressure once packers (and/or a liner hanger) are set. This PSSD technology, which is integrable to almost any type of sand control screen, is equipped with a backup contingency should the primary mechanism fail to open. Once opened, the installed PSSDs can be shifted mechanically with unlimited frequency. The two- or three-position valve can be integrated with inflow control devices (ICDs) (includes autonomous ICDs/autonomous inflow control valves) and allows mechanical shifting at any time after installation to close, stimulate or adjust ICD settings. After a computer-aided design stage to achieve all the operational/mechanical requirements, prototypes were built and tested, followed by field installations. The design stage provided some challenges even though the pressure-activation feature was being added to a mature/proven SSD technology. Prototype testing in a full-scale vertical test well proved valuable because it revealed failure modes that could not have appeared in the smaller-scale laboratory test facilities. Lessons learned from the first field trial helped improve onsite handling procedures. The production logging tool run on first installation confirmed the PSSDs with ICDs opened as designed. The second field installation involved a different size and configuration, in which PSSDs with ICDs performed as designed. The unique two- or three-position PSSD accommodates any type of sand control or debris screen and any type of ICD for production/injection. The PSSD allows the flexibility to change ICD size easily at the wellsite. Therefore, this technology can be used in carbonate as well as sandstone wells. Wells that normally could not justify the expense of existing single-trip completion technologies can now benefit from the cost savings of single-trip completions, including ones that require ICD and stimulation options.

The Cost

Due to the ongoing trend of increased higher education costs, state and federal strategies have been implemented in an effort to lower students' cost of college. One such strategy gaining nationwide attention is the implementation of open educational resources (OER) to lower the cost of textbooks. This chapter describes how a higher education institution can support and scale the diffusion of OER adoption by presenting a framework based on Everett Rogers's diffusion of innovation theory, with a focus on engaging the “early majority” in this process to sustain the innovation. The development of the framework and a case study of its implementation and evaluation within a community college district are presented to guide other higher education institutions in the scaling of OER adoption. The chapter also considers influences on the framework that constrain, accelerate, or support OER adoption, and presents implications and recommendations based on lessons learned.

This chapter discusses critical success factors in the design, implementation, and utility of a new construct and interface for data transfer with broad applicability to clinical data set management. In the context of a data coordinating center for evaluating cardiovascular outcomes in high-risk women, we detail and provide a framework for bridging the gap between extensible markup language (XML) and XML schema definition file (XSD) in order to provide greater accessibility using visual basic for applications (VBA) and Excel. Applications and lessons learned are discussed in light of current challenges to healthcare information technology management and clinical data administration. The authors hope that this approach, as well as the logic utilized and implementation examples, will provide a user-friendly model for data management and relational database design that is replicable, flexible, understandable, and has broad utility to research professionals in healthcare.

This case describes the implementation of an online travel management system at FED-AK, the Alaska office of a U.S. government agency. The previous system was intended to accomplish the same functionality, but due to employee resistance, it was used only as a forms generator in conjunction with a paper- and mail-based process. The new system is integrated, which compels employees to use all the functionality provided. It also incorporates many lessons learned from the old system—in particular, extensive training and online help functions. The system is expected to significantly reduce the cost of travel by minimizing errors, enforcing policies, and reducing transaction costs. The system will also lead to faster reimbursement of employee travel expenses.
