performance   evaluation in regular periods is one of the ways in which organizations can   evaluate their performance as well as weak and strong points unifiedly and   precisely. these days, mathematical models are also used to evaluate the   efficiency and productivity of various units. these units are a collection of   education, research and service activities as input and output factors an...

The efficiency of a nation’s progress is determined by variety factors; however, transportation plays critical role in boosting because it facilitates trade and communication between countries. majority powered fossil fuels such as gasoline or diesel, which will be depleted less than 50 years. Another option to operate systems after replacing conventional vehicles with electric (EV). Powering t...

The paper focuses on the application of equation-based object oriented languages to creating models for modelbased diagnosis. We discuss characteristics and language constructs essential for diagnostic purposes. In particular, we describe the main features of the declarative modeling language Rodelica, which is based on the well-known language Modelica but enhances it with additional features r...

The calibration of SCIAMACHY was thoroughly checked since the instrument was launched on-board ENVISAT in February 2002. While SCIAMACHY’s functional performance is excellent since launch, a number of technical difficulties have appeared, that required adjustments to the calibration. The problems can be separated into three types: (1) Those caused by the instrument and/or platform environment. ...

Aircraft engine performance trend monitoring and gas path fault diagnostics are closely related technologies that assist operators in managing the health of their gas turbine engine assets. Trend monitoring is the process of monitoring the gradual performance change that an aircraft engine will naturally incur over time due to turbomachinery deterioration, while gas path diagnostics is the proc...

Over the last decade and continuing into the foreseeable future, a trend has developed in the spacecraft industry of both number of missions and the amount of data taken by each mission increasing faster than bandwidth capabilities to send these data to Earth. The result of this trend is a bottleneck between data gathering (on-board) and data analysis (on the ground.) This bottleneck can be ove...

This work focuses on evolving purposeful collective behavior in a swarm of Jasmine micro-robots. We investigate the stability of the online and on-board evolutionary approaches, where mutation, crossover as well as fitness calculation are performed only by interacting micro-robots without using any centralized resources. In this work it is demonstrated that the environment-adaptive collective b...

We are developing frequency stabilized lasers in support of NASA’s time-varying-gravity mapping missions. Small changes in the distance between spacecraft will be detected using interferometric techniques between two satellites with on-board stable lasers.
