In this paper, condition monitoring of a geared rotor system using finite element (FE) model updating and particle swarm optimization (PSO) method is onsidered. For this purpose, employing experimental data from the geared rotor system, an updated FE model is obtained. The geared rotor system under study consists of two shafts, four bearings, and two gears. To get the experimental data,  iezoel...

1 Abstract: In the frame of the FAST20XX project under the supervision of ESA, two hybrid rocket engines are developed at Université Libre de Bruxelles (ULB) in collaboration with the Royal Military Academy of Belgium to assess the performance of paraffin/N2O propellants. The goal behind the study is to measure the regression rate and optimize the size of ALPHA, which is a sub-orbital vehicle d...

Introduction The two-hybrid system (THS), first introduced by Fields and Song (1989) (Ref. 1), is a powerful technique for identifying new proteins involved in specific biological processes. It allows for the rapid isolation of the gene that codes for a protein that interacts with a specific protein of interest. Here, we present not a review of the current THS technology but, rather, a comprehe...

in most industrial applications, including overhead cranes, two motors with equal speeds are required. to meet this, different traditional and modern methods are used. in the modern methods, work is done with more precision but the cost is remarkably high, also the maintenance of equipment needs specialized personnel. among traditional methods, the two-motors selsyn method is noteworthy due to ...

4-tert-Octylphenol (4-t-OP) was treated with the white rot fungus Phanerochaete sordida YK-624 under ligninolytic condition with low-nitrogen and high-carbon culture medium. 4-t-OP completely disappeared after 5 days of treatment and the activities of ligninolytic enzymes, laccase and manganese peroxidase (MnP), were detected during this period, thus suggesting that the disappearance of 4-t-OP ...

This paper proposes a speciication language, Hybrid Projection Temporal Logic (HPTL), for the purpose of modelling, analyzing and verifying hybrid systems consisting of a non-trivial mixture of discrete and continuous components. The syntax and semantics of HPTL are presented, and some examples of hybrid systems are modelled with HPTL to illustrate the formalism.

The direct interaction of the Escherichia coli cytotoxin RelE with its specific antidote, RelB, was demonstrated in two ways: (i) copurification of the two proteins and (ii) a positive yeast two-hybrid assay involving the relB and relE genes. In addition, the purified RelE protein exhibited ribosome-binding activity in an in vitro assay, supporting previous observations suggesting that it is an...

A spatial parallel mechanism namely 3-RRS mechanism has been assigned to be attached to the seat of a standard electric wheelchair to prevent the turning over of the handicapped sitting on the wheelchair. The system of the wheelchair and the mechanism is a self-balancing robotic wheelchair and has coped with several road conditions. A stability control system calculates the proper moments on th...
