Dynamic Recrystallization and Recovery Behaviors in Austenite of a Novel Fe-1.93Mn-0.07Ni-1.96Cr-0.35Mo Ultrahigh Strength Steel

Due to the complex composition and high proportion of alloys in traditional ultrahigh strength steel, the dilemma caused by ultrahigh strength and low toughness in casting and forging processes requiring subsequent heat treatment can be mitigated with an efficient and economical rolling process. In this work, the effect of deformation parameters on dynamic recrystallization (DRX) and dynamic recovery (DRV) is discussed through stress-strain analysis, the DRV mathematical model is obtained, and then the dynamic recrystallization activation energy, Zener–Hollomon equation, and hot working equation are obtained. The critical strain of DRX detected by the P-J method is ε c / ε p = 0.631 , which indicates that dynamic recrystallization of this novel steel is relatively easy to achieve by the rolling process. These models and conclusions have potential to be generalized for the formulation of process specification and process configuration without requiring extensive material testing.

Generating Block-Structured Parallel Process Models by Demonstration

Programming by demonstration (PBD) is a technique which allows end users to create, modify, accommodate, and expand programs by demonstrating what the program is supposed to do. Although the ideal of common-purpose programming by demonstration or by examples has been rejected as practically unrealistic, this approach has found its application and shown potentials when limited to specific narrow domains and ranges of applications. In this paper, the original method of applying the principles of programming by demonstration in the area of process mining (PM) to interactive construction of block-structured parallel business processes models is presented. A technique and tool that enable interactive process mining and incremental discovery of process models have been described in this paper. The idea is based on the following principle: using a demonstrational user interface, a user demonstrates scenarios of execution of parallel business process activities, and the system gives a generalized model process specification. A modified process mining technique with the α|| algorithm applied on weakly complete event logs is used for creating parallel business process models using demonstration.

Optimization Performance Integral Criteria Based on Hybrid Soft Computing for QTS System

This research work proposed MPSO methods for nonlinear complex QTS process. This system is implemented in various process control industries, design, and development of a new controller to increase the better stability and improve the performance of integral criteria. This proposed work goal is to minimize parameters for process controller by statistical Taguchi method combined with mutation particle swarm optimization algorithm for industrial laboratory highly complex nonlinear QTS. The designed value is tested using Simulink model in MATLAB. Using proposed controller values are tested in the real experiment set up and experiment output response is reached. The various controller designed are PID controller for QTS. The result shows that TMPSO technique is provided the good result when compared with other approaches. The TMPSO techniques use for setting controller offers enhanced process specification such as better time domain specifications, smooth error reference tracking, and minimization of error in the nonlinear system.

Verfahrenskonzept zum Auftrag metallischer Partikel/Process specification for depositing metallic particles

Das vorgestellte Verfahrenskonzept basiert auf der Führung von Partikeln durch ein durchströmtes und erhitztes Kapillarrohr. Mit der Kapillarrohrströmung werden dabei die für einen anschließenden Materialauftrag notwendigen Partikeleigenschaften erzeugt. Dieser Prozess wird in diesem Beitrag mithilfe eines Berechnungsmodells analysiert, indem das Modell auf eine konkrete Geometrie und geeignete Randbedingungen angewandt wird.   This paper presents a process for guiding particles through a heated capillary with an internal flow. The capillary flow creates the particle properties needed for the subsequent material deposition. This process is analyzed using a calculation model, applying the model to a concrete geometry and suitable boundary conditions.

Bud-Derivatives, a Novel Source of Polyphenols and How Different Extraction Processes Affect Their Composition

The use of herbal food supplements, as a concentrate form of vegetable extracts, increased so much over the past years to count them among the relevant sources of dietetic polyphenols. Bud-derivatives are a category of botanicals perceived as a “new entry” in this sector since they are still poorly studied. Due to the lack of a manufacturing process specification, very different products can be found on the market in terms of their polyphenolic profile depending on the experimental conditions of manufacturing. In this research two different manufacturing processes, using two different protocols, and eight species (Carpinus betulus L., Cornus mas L., Ficus carica L., Fraxinus excelsior L., Larix decidua Mill., Pinus montana Mill., Quercus petraea (Matt.) Liebl., Tilia tomentosa Moench), commonly used to produce bud-derivatives, have been considered as a case study. An untargeted spectroscopic fingerprint of the extracts, coupled to chemometrics, provide to be a useful tool to identify these botanicals. The targeted phytochemical fingerprint by HPLC provided a screening of the main bud-derivatives polyphenolic classes highlighting a high variability depending on both method and protocol used. Nevertheless, ultrasonic extraction proved to be less sensitive to the different extraction protocols than conventional maceration regarding the extract polyphenolic profile.

Towards standardisation of evidence-based clinical care process specifications

There is a strong push towards standardisation of treatment approaches, care processes and documentation of clinical practice. However, confusion persists regarding terminology and description of many clinical care process specifications which this research seeks to resolve by developing a taxonomic characterisation of clinical care process specifications. Literature on clinical care process specifications was analysed, creating the starting point for identifying common characteristics and how each is constructed and used in the clinical setting. A taxonomy for clinical care process specifications is presented. The De Bleser approach to limited clinical care process specifications characterisation was extended and each clinical care process specification is successfully characterised in terms of purpose, core elements and relationship to the other clinical care process specification types. A case study on the diagnosis and treatment of Type 2 Diabetes in the United Kingdom was used to evaluate the taxonomy and demonstrate how the characterisation framework applies. Standardising clinical care process specifications ensures that the format and content are consistent with expectations, can be read more quickly and high-quality information can be recorded about the patient. Standardisation also enables computer interpretability, which is important in integrating Learning Health Systems into the modern clinical environment. The approach presented allows terminologies for clinical care process specifications that were widely used interchangeably to be easily distinguished, thus, eliminating the existing confusion.

Business process specification, verification, and deployment in a mono-cloud, multi-edge context

Despite the prevalence of cloud and edge computing, ensuring the satisfaction of time-constrained business processes, remains challenging. Indeed, some cloud/edge-based resources might not be available when needed leading to delaying the execution of these processes? tasks and/or the transfer of these processes? data. This paper presents an approach for specifying, verifying, and deploying time constrained business processes in a mono-cloud, multi-edge context. First, the specification and verification of processes happen at design-time and run-time to ensure that these processes? tasks and data are continuously placed in a way that would mitigate the violation of time constraints. This mitigation might require moving tasks and/or data from one host to another to reduce time latency, for example. A host could be either a cloud, an edge, or any. Finally, the deployment of processes using a real case-study allowed to confirm the benefits of the early specification and verification of these processes in mitigating time constraints violations.
