Rapid technical advancement has seen a move away from more traditional methods of mine clearance operations such as the use of divers in favour of using unmanned and remote vehicles. Remotely Operated Vehicles (ROVs) are now used extensively in offshore and military operations for complex inspection tasks where Dynamic Positioning (DP) software is used to reduce operator workload and provide stability...
The mining of software repositories has provided significant advances in a multitude of software engineering fields, including defect prediction. Several studies show that the performance of a software engineering technology (e.g., prediction model) differs across different project repositories. Thus, it is important that the project selection is replicable. The aim of this paper is to present STRESS,...
Operating system level virtualization containers are commonly used to deploy virtual network functions (VNFs) which access the centralized network controller in software-defined networking (SDN) infrastructure. While this allows flexible network configuration, it also increases the attack surface, as sensitive information is transmitted between the controller and the virtual network functions. In...
Commit comments increasingly receive attention as an important complementary component in code change comprehension. To address the comment scarcity issue, a variety of automatic approaches for commit comment generation have been intensively proposed. However, most of these approaches mechanically outline a superficial level summary of the changed software entities, the change intent behind the code...
This paper focuses on the systematic design and development of an optimized embedded system platform from ground up to handle special real-time requirements of control applications. An embedded system is usually embedded as a part of a complete device including hardware and mechanical parts, and both the hardware system and the software system are tailored and optimized to realize specific functions...
The questions of training simulators development technique for oil and gas industry automation control systems are considered. The possibility of using this technique for control systems based on mathematical and algorithmic control models is introduced. A mathematical model is used. The training simulator operating result is the process studying, learning management skills, adjusting parameters to...
There are many function modules in the numerical control (NC) system, the system needs to communicate with each other through the data interaction among modules, to coordinate the work between modules and complete the control task. In this paper, the main function module structure of NC system is constructed based on RCS method. The communication between the NC system modules is realized by using...
This report shows that the architecture of Big Banks' Management Control Systems can be presented as a two or three-tier structure without separating the functional components to the front and back office. The report also examines the key legislative and regulatory documents that define the specific requirements for the Big Banks' Management Control Systems' Software. Functional components' classification...
Optoelectronic pulsars' (OEP) processor is developed for registration of radio emission from pulsars — cosmic sources. OEP processor includes an acousto-optic spectrum analyzer and a digital signal processor. The structure, operation principle and hardware implementation of the processor are presented. Software that works in real time is reviewed. The results of pulsars radio emission registration...
Integrated Computer Control System (abbr. ICCS) of large-scale laser facility uses a scalable software architecture to manage more than 10,000 control points to operate 48 powerful laser beamlines, provides for the integration of all elements of laser and target area distributed subsystems to form an overall operational control system. Fault detection and diagnosis test are the important technique...
The water tank system is widely used for demonstration purposes in control engineering. This paper describes a training system for process automation, an ideal way to teach and learn about important aspects of automation. We present the implementation of a micro plant incorporating intelligent instruments. We also describe a set of teaching tools to facilitate the learning of concepts related to linear...
A key feature of Software Defined Network is the decoupling of control pane and data plane. Although delivering huge benefits, such a decoupling also brings a new risk: the data plane states (i.e., flow tables) may deviate from the control plane policies. Existing data plane testing tools like Monocle check the correctness of flow tables by injecting probes. However, they are limited in four aspects:...
In Software Defined Networking (SDN), connections between the controller and the switches are maintained in two ways: out-of-band and in-band. In out-of-band controlling, the control channels are constructed via separate links. However, due to several reasons, sometimes in-band controlling is needed instead of out-of-band controlling. In in-band controlling, the data paths are used for control channels...
Current Software-Defined Networking (SDN) switch examines many packet headers to support the flow-based packet forwarding. To support the application-based forwarding for a service function chaining (SFC), SDN switch requires packet header modifications to identify the processing status and multiple packet matchings to steer the network traffics to different VMs in a specific order. Both challenges...
The need to improve the quality of management at minimum costs, the complexity of the structure of the management object, the functions performed by it, leads to an increase in uncertainties that need to be taken into account. Application of typification and unification will allow to reduce the cost of production of new products, to increase the level of automation of productions.
