The Educational Irish Research Satellite, EIRSAT-1, is a project developed by students at University College Dublin that aims to design, build, and launch Ireland's first satellite. EIRSAT-1 is a 2U CubeSat incorporating three novel payloads; GMOD, a gamma-ray detector, EMOD, a thermal coating management experiment, and WBC, a novel attitude control algorithm. The EIRSAT-1 project is carried out with the support of the Education Office of the European Space Agency, under the educational Fly your Satellite! programme. The Assembly, Integration and Verification (AIV) plan for EIRSAT-1 is central to the philosophyand the development of the spacecraft. The model philosophy employed for the project is known as the 'prototype' approach in which two models of the spacecraft are assembled; an Engineering Qualification Model (EQM) and a Flight Model (FM). The payloads, GMOD and EMOD, and the Antenna Deployment Module (ADM) platform element warrant a Development Model (DM) in addition to an EQM and a FM, as they have been designed and developed inhouse. The engineering qualification model serves as both a FlatSat for electrical integration testing and as a representative model for testing of software code, patching and operational decisions during the active mission. The EQM is tested to qualification levels and durations during the environmental test campaign. The flight model contains the flight versions of the payloads, ADM platform element and the procured hardware elements. It undergoes acceptance level testing and it is the final spacecraft to be delivered to ESA for flight. After successful completion of the Critical Design Review (CDR) and Ambient Test Readiness Review (ATRR) phases of the project, the EQM of EIRSAT-1 will be assembled and integrated in University College Dublin. After assembly and integration of the EQM, the project will begin the ambient test campaign, in which the EQM undergoes ambient functional and mission testing. This work details the preparation and execution of the assembly, integration, and verification activities of EIRSAT-1 EQM.

In this paper, we describe a technique to construct accurate stochastic simulation models from acquired trace data. The resulting simulation models accept input trace data and return estimates of disk request service times. In addition, we describe a trace collection technique capable of collecting accurate trace data from Novell Netware servers. These traces are used to construct a simulation model of a Novell Netware I/O subsystem that, is used to study the impact of disk data reorganization on I/O performance.
