A method for assessment of reliability of the network is developed, which uses the features of the fault tree analysis. The method is developed in a way that the increase of the network under consideration does not require significant increase of the model. The method is applied to small examples of network consisting of a small number of nodes and a small number of their connections. The resul...

Reliability and availability of the equipment or plants used in construction and civil engineering field is significant issue for all stakeholders. Unexpected breakdown and repairs could cause serious consequences such as extra cost and project period extension. Therefore, it is necessary to study the reliability of the construction equipment and predict the failures in time with a reasonable d...

Reliability is an important consideration in the planning, design and operation of engineeringsystems. As the size and complexity of mining equipment continue to increase, the implica-tions of equipment failure become ever more critical. One method to mitigate the impact offailures is to improve the reliability of the equipment. One of the purposes of system reliabil-ity analysi...

The present research aims at predicting the required activities for preventive maintenance in terms of equipment optimal cost and reliability. The research sample includes all offshore drilling equipment of FATH 59 Derrick Site affiliated with National Iranian Drilling Company. Regarding the method, the research uses a field methodology and in terms of its objectives, it is classified as an app...

Digital signal processing (DSP) underpins modern wireless and wireline communications, medical diagnostic equipment, military systems, audio and video equipment, and countless other products, becoming increasingly common in consumers' lives. Due to advances in semiconductor technology, ever more complex DSP algorithms, protocols, and applications are now feasible, which, in turn, increase the c...

In this paper we present a novel method for reliability testing of MEMS devices containing movable structures. A small size, simple and cheap vibration fatigue test equipment was designed and realized at BUTE and vibration fatigue tests were carried out on 10 samples of a LIS0L02AS4-type MEMS 3-axis inertial sensor provided by ST Microelectronics. The paper presents the test plan, the test equi...

This paper is part of the development process of a microsurgical "cooperating" assistant. To evaluate its applicability to augment fine surgical motions, we test precision and operator perception in simple microsurgical scale pick and place motions. Such motions are common in microsurgical procedures(e.g. micro-vascular anastomosis). The experiments test the users' ability to position a common ...
