Although many works are available in the literature on the applications of standby redundancy, the system components are assumed to be independent of each other. But, in reality, the system components can be dependent on one another, causing the failure of each component to affect the failure rate of the remaining active components. In this paper, a standby two-unit system is considered, assuming a dependency between the switch and its associated active component.Design/methodology/approachThis paper assumes that the failures between the switch and its associated active component follow the Marshall–Olkin exponential bivariate exponential distribution. Then, the reliability analysis of the system is done using the continuous-time Markov chain method.FindingsThe derived equations application to determine the system steady-state availability, system reliability and sensitivity analysis on t...

Both the units are active at the initial stage. Unit one is taken as priority and unit two is taken as non-priority. Unit one after the repair is considered as a degraded unit. An inspection is performed to check the feasibility of the unit, if the unit does not work properly it is replaced by a new one while as a non-priority unit after repair becomes as good as new. The system is in downstate only in case both the unit fails or are under repair. The failure of Non priority unit may be of casual nature which needs no replacement and system start functioning normally after repair.

The examination of disguised body writing deals with the analysis of documents for handwriting or script having a wilful modification of a person’s original writing for the purpose of concealing his/her identity. The analysis of such cases of disguised writing involves the identification and examination of class and individual handwriting characteristics to establish the identity of the author and to determine the source of the handwriting. The objective of the present work was to study a few cases of master disguised handwriting and to compare them based on particular individual characteristics to establish the identity of the writer. After the proper analysis, it was found that even the cases of master disguise will possess some aspects through which the authenticity of the document and the identity of the writer can be scientifically established.

INTRODUCTION Reliable functioning of embedded systems is of paramount concern to the billions of users that depend on these systems every day. Unfortunately most embedded systems still fall short of user's expectation of reliability. The incorporation of redundancy is one of the important techniques to improve the reliability and hence the effectiveness of the system. The system models with standby redundancies have been frequently analysed by various authors with different assumptions due to their vital existence in modern industries and business. Gupta, Tyagi and Kishan [6] discussed the concept of a two unit system with correlated failures and repairs and random appearance and disappearance of repairman. Kishan and Jain [8] analysed a two non-identical unit standby system model with repair, inspection and post-repair under classical and Bayesian viewpoints. Agnihotri and Satsangi [1] considered two unit identical systems with priority based repair and inspection. While Tuteja and Malik [9] discussed about reliability and profit analysis of two single unit models with three modes and different repair policies of repairman who appears and disappears randomly. Goel, Sharma and Gupta [2] worked on cost analysis of a system with intermittent repair and inspection under abnormal weather. Further Joorel, Kumar and Lal [3] put forth the concept of Reliability analysis of a complex system composed of two parallel subsystems without considering random appearance and disappearance of repairman in the system. Gupta, Goel and Tomer [7] provided the concept of analysis of a two unit standby system with correlated failure and repair and random appearance and disappearance of repairman. Nakagawa and Osaki [5] investigated stochastic behavior of two unit priority standby redundant system with repair. Recently Kakkar, Chitkara and Kumar [4] discussed reliability analysis of a cold standby system with repair equipment failure and appearance and disappearance of repairman with correlated lifetime. The purpose of the present paper is to put forth the concept of random appearance and disappearance of repairman in the system. The system comprises of two non-identical units A and B, each unit having two modes Normal and Failure in which unit A is operative and unit B is kept in standby mode. Upon failure of operative unit, unit B

There are two types of repairman: ordinary and expert repairman. The expert repairman is called only when system breaks down. Two types of repair facility is available to repair failed unit in which A gets priority for repair and is repaired by expert and B and C are repaired by ordinary repairman on first come first service basis. Further, if unit A is repaired by expert and during the process unit B or C fails, then that unit is also repaired by expert repairman till the system becomes operative. The failure of units B and C are mutually dependent i.e. the unit-B fails with increased failure rate if the unit-C has failed. ...

This process is of critical importance, as it enables the criminal to enjoy these profits without jeopardizing their source. The main aim of the paper is to identify and analyze a significant change to cope up with the money laundering schemes, which is taking place in different countries, and to determine the risk factor that is associated with them in the recent past. The purpose of the study is also to investigate how UAE is able to combat with money laundering activities by implementing the anti-money laundering (AML) regime and how special unit of AML are implemented for the aforementioned purpose. The findings of the present research study shows that there is a substantial transformation that could be seen in reducing the money laundering schemes which had been taking place in various countries over the years. The research study also shows that UAE has passed over the expectation of promoting stability and improving foreign investment or trade in the country by strictly abiding to launch measures to compete with money laundering activities.
