Error Detection and Correction System (EDAC) of On Board Data Handling (OBDH) in Real Time Operating System Behaviour
free download

The satellite requires the support of a robust sub system . On Board Data Handling (OBDH) is the core function of the satellite subsystem and has to be error free in managing the operation of the satellite. It should withstand the harsh environmental conditions in space

A solution for Overcurrent Mitigation developed for a Crop Cobble Shear System operating in a Steel Rolling Mill
free download

The paper describes the utilization of the Direct Torque Control (DTC) drive technology to control the Crop Cobble Shear (CCS) system in a steel rolling mill. The CCS is a highly dynamic load that requires a drive capable for high performance torque control. During the

A PVT Cooling System Design and Realization: Temperature Effect on the PV Module Performance Under Real Operating Conditions
free download

It is established that the efficiency of the most common solar cells decreases when their temperature increases. The photovoltaic module characteristics, especially its efficiency and its maximum power, are defined in standard test conditions (STC), while their nominal

System approach to operating transport structures geodynamic safety estimation
free download

Extensive transport facilities (ETF), including railways, stretch for many thousands of kilometers, crossing the territories with different geodynamic activity. The constructions of transport structures, as a rule, are designed for a long service life and the cost effectiveness for eliminating

Software-based methods for Operating system dependability
free download

Guaranteeing correct system behaviour in modern computer systems has become essential, in particular for safety-critical computer-based systems. However all modern systems are susceptible to transient faults that can disrupt the intended operation and function of such

Operating System Support for Fan-Out File Systems
free download

Stackable file systems are a portable mechanism to extend file system functionality without the complexity of creating an entirely new disk-based or network-based file system . Normally, applications execute system calls, then the VFS calls, the file system directly. With

A Geographical Information System (GIS) Based Traceability System Suggestion for a Pastry Firm Operating Nationwide
