In a process-based organization, while actors perform their actions, multiple business transactions instances are running concurrently. Due to this raising complexity, during the business operation many risks may manifest when comparing the prescribed business transactions with its instances. The manifestation of a risk is a non-conformance behavior during the execution of transactions. Some risks...
Security vulnerabilities in industrial control systems (ICS) and its open interconnected trends lead to security risks escalating. The existed security protection technologies, with poor applicability, are hard to meet the special requests of information security for ICS. In this paper, trusted protection theories and technologies for ICS were studied and an integrated trusted protection model was...
Single-layer flow and accumulated flow monitoring of Injection-production engineering technology is a necessary means to ensure precise injection and effective water. This paper uses the vortex principle to achieve flow measurement interval. However, underground injection wells in the environment, its sensor by water injection piping vibration and noise caused the flow field disturbance double interference...
This study investigates the use of smart monitoring systems in preventing malfunctions in several parameters (temperature, pressure and pH) for a bio gas installation aiming to turn paper effluents into a useful bio gas able to power or heat other systems. These bio digesters help conserving the clean aura of our environment in two major ways: reduce waste and provide valuable energy.
Data access is key to science driven by distributed high-throughput computing (DHTC), an essential technology for many major research projects such as High Energy Physics (HEP) experiments. However, achieving efficient data access becomes quite difficult when many independent storage sites are involved because users are burdened with learning the intricacies of accessing each system and keeping careful...
Refractive index is a physical property which can be used in determining the end point of transesterification in producing biodiesel. The traditional method in acquiring refractive index measurements takes place outside of a transesterification reactor making remote sensing impossible. In this study, a fiber optic cable was used to identify the appropriate wavelength to acquire the refractive index...
Comparing the capability of processes is an essential task in the manufacturing industry. Selecting the process with a higher yield is critical to maintaining production quality and cost. With the miniaturization of physical dimensions and lower power consumptions, microelectromechanical systems (MEMS) are widely applied in various domains. This research compares two processes that produce the pre-amplifier...
Wafer level package (WLP) is one of the fastest growing segments in the semiconductor packaging industries. Low costs, small sizes, and the ease of logistics make WLP a main-stream packaging solution for a single chip. However, different from conventional packages, WLP has no final test (FT) and only relies on wafer level probing for functional test, which may induce the trouble that once wafer probing...
In industry with a high level of investment, such as Arctic offshore oil and gas, the costs of the production losses due to a long downtime are substantial which can affect business performance. Thus the selection of the maintenance policy for the Arctic is one of the most important decisions of strategic maintenance management. It guarantees not only adequate control of the maintenance costs, but...
This paper presents a remote monitoring system based on the SCADA model (Supervisory Control And Data Acquisition), specifically developed for automated production processes in a food company. The goals defined for this project were the monitoring of three production lines and six silos of raw materials, along with the indication / evaluation of three performance measures demanded by the company:...
A monitoring method is introduced that creates, in near real-time, two-dimensional (2D) maps of the soil gas distribution. The method combines linear gas sensing technology for in-situ monitoring of gases in soil with the mapping capabilities of Computed Tomography (CT) to reconstruct spatial and temporal resolved gas distribution maps. A weighted iterative algebraic reconstruction method based on...
Software Defined Networking (SDN) is one of the typical flow-rule-driven networks. In SDN, a centralized controller dictates the network behavior and configures network devices with many flow rules, and the validity and consistency of flow rules could guarantee the normal operations in SDN. Therefore, SDN requires a secure and efficient mechanism to manage and authenticate flow rules between the application...
Virtualization technologies in a cloud computing system enable its users to create and delete virtual machines easily. This flexibility accelerates the update cycle of applications to keep up with user demand. When updating applications, the application management process should also be modified. If necessary changes in the management process are overlooked, this lack of changes can cause inconsistencies...
With restrict of market and society policy, some manufacturing firms' profit becomes less and less especially in the hydraulic fracturing field. This paper proposes a hydraulic fracturing product service system (HF-PSS) as a new firm strategy to shift from product-centered paradigm to service-centered paradigm for maximizing profit and totally satisfying customer needs to tackle this dilemma. Considering...
This paper shows the performance of a PV system under shadow projection on PV panels. The reconfiguration techniques, employing a microprocessor-based system, modifies the layout of the PV plant by physically changing the connections among modules, in order to recover the loss of power due to the shadows. Different cases have been considered to evaluate the increase of power.
The task of identifying critical fluctuations of the production characteristics from the normal value are considered in the article. An algorithm based on the least squares method, which allows for an increase of efficiency and accuracy in identifying problematic situations in production is developed in the course of research. Experimental research of the developed algorithm was performed using four...

Big Data is one of the most discussed trend themes worldwide in both research community and industrial practice. Thus, researchers as well as company representatives focus on the study of Big Data technologies and the potentials deriving from gaining and structuring data. In this paper, we firstly conduct a literature review. Then, we describe the approach to implement reaction management in manufacturing...
The Mu2e experiment at Fermilab proposes to search for the coherent neutrino-less conversion of muons to electrons in the presence of a nucleus. The experimental signature for an aluminum target is an isolated 105 MeV electron exiting the stopping target no earlier than ∼700 ns after the pulse of proton beam hits the production target. Any protons that hit the production target in between the pulses...
