Planning for a network is important for deployment of any network. For large capacity network, planning has to be done to increase efficiency and therefore setting up a test-bed to perform even a basic test would be really difficult. Planning tool will give a mirror image of the actual network, thereby ensuring that there are no gaps in what is being planned and what is being deployed. The software...
In order to satisfy the need of cross platform, fault information standard description, and network transmission in networked fault diagnosis, the paper introduced the specific planning and implementation method based on LabVIEW. Relevant research was based on the capacities of LabVIEW cross platform and of XML standard description. The XML description method of typical fault information was given...
Virtual machine development can strengthen the use and management of server resources, which can result in a higher server efficiency utilization ratio. This study proposed a method suitable for enterprises to develop virtual machines, and elaborated the mode, execution steps and main content of each step of virtual machine development. The implementation process equals to the behavior of computer...
In 2010 I have had an opportunity to work with a team of fantastically intelligent system administrators. Their team dynamics and project was completely different from software projects I have worked with before. We have tried Scrum which did not work at all due to too unstable environment. We also failed using Kanban because of the lack of boundaries, which led to coming back to guerilla-style work...
The development of a virtual machine is an important method for fulfilling "green IT energy saving and carbon reduction" and "cloud computing". However, there is a server capacity planning problem, the calculation of the number of physical machines required to contain the virtualized operating servers with mathematical model planning. This study implemented and developed relevant...
Software reviews are one of the most efficient quality assurance techniques in software engineering. They are required for the enhancement of the software quality in early phases of the development process and often used in development of safety critical systems. In the field of software engineering for Air Traffic Management (ATM) the standard DO-278/ED-109 requires the rigorous application of code...
Many domestic enterprises not only procurement costs, labor costs remain high. Especially with the continuous development of enterprises, procurement has expanded the traditional mode of operation and methods of procurement can not meet the needs of modern enterprise procurement. In order to achieve the pursuit of efficiency and effectiveness, the establishment of procurement management information...
Human-in-the-loop (HITL) simulations can be invaluable in the study of traffic flow management concepts. However, the design and execution of HITL experiments is often very challenging and risk-prone. In our market-based Traffic Flow Management (TFM) research, we develop an approach to developing HITL simulations that leads to effective experiments that yield great results, while reducing programmatic...
The Mars Exploration Rover Mission (MER) includes the twin rovers, Spirit and Opportunity, which have been performing geological research and surface exploration since early 2004. The rovers' durability well beyond their original prime mission (90 sols or Martian days) has allowed them to be a valuable platform for scientific research for well over 2000 sols, but as a by-product it has produced new...
Component deployment directly affects the performances of component-based distributed applications, such as response time, throughput, reliability, and security. It also affects resources utility of runtime environment. In order to reduce the cost of resources used by applications and improve the resources utility, this paper defined component graph to represent component-based distributed applications,...
The simplistic design of the original Internet is being slowly replaced by the presence of advanced middleboxes that are introduced in the network. While some of these middleboxes are transparent and passively monitor the network, others can directly affect the data traffic (e.g., content accelerators). Forecasting user and middlebox traffic patterns are usually done through oversimplified models...
Virtualisation technologies widely affect best practice for dependability of services and networks, and suggest novel approaches for dependable configurations. Starting from an existing tool, that computes dependable configurations for traditional information systems, we analyse how to change its configuration strategies when moving to virtual environments.
With the rapid development of mobile computing, distributed computing and Web Service, computing environments for software have become more and more open, complicated and multivariate. More attention has been focused on how to design an adaptive and dynamic software architecture to meet the changing software computing environment. First, this paper introduces the open Service Gateway Initiative (OSGi)...
The rich variety of unmanned robotics at NASA's Jet Propulsion Laboratory sets the bar for innovations in activity planning. The Operations Planning Team at JPL, co-winner of the NASA Software of the Year award in 2004, is continuously working to enhance the capabilities and user experience for long term and real-time planning operations. Spatial Querying improves the efficiency of planetary surface...
Distributed sensor Webs typically operate in dynamic environments where operating conditions, transient phenomena, availability of resources, and network connection quality change frequently and unpredictably. Often these changes can neither be completely anticipated nor accurately described during development or deployment. Our prior work has described how we developed agents and services that are...
This paper introduces a security design for an e-business environment with the use of the three-layered e-business architecture. This security design proposes best practices in general. It involves different stages of the management process (planning, deployment, administration, and auditing) and security control by layers - from physical access, to network communication, to operating systems, to...
This document describes how the DESEREC framework can be enhanced through the usage of an offline learning loop. This mechanism consists basically of computational methods and techniques which enable the framework to gradually improve the effectiveness of its behaviour, by analysing internal data produced by some of the modules, applying some learning algorithms to them and to the information received...
Using an in-house developed software the signal level, the best server cells, and the amount of interference using standard propagation models are determined in a cellular environment. The program is also able to assign the frequency channels automatically to the TRXs taking into account the carrier to interference and the traffic distribution using a genetic algorithm. In this paper, the cost function...
