<em>Nigeria&rsquo;s power supply has been experiencing incessant interruptions due to failures in the distribution system. The availability assessment of power system is a necessary criterion in meeting the customer&rsquo;s demand. In this study, the availability of three 11kv feeder in Benin Electricity Distribution Company (BEDC), Edo State Nigeria were evaluated. These was carried out by collating the failure data which includes; time of failure, time outage was restored, outage duration, causes of failure, and load interruption from the Injection substations G.R.A Injection substations for

A company's ability to meet its goals depends heavily on the smooth operation of its production process. To ensure that the production machinery operates smoothly and without any breakdowns, it is essential to implement effective maintenance that addresses any issues related to the equipment. This research aims to identify the root causes of equipment failure in the soda and dolomite bucket elevator by analyzing the Mean Time Between Failure (MTBF), Mean Time to Repair (MTTR), and conducting a qualitative evaluation using Failure Mode Effects Analysis (FMEA).

The calculation of mean time between failures (MTBF) is of significance in reliability engineering. The precondition before calculation of MTBF is to make sure what failure model the numerical control (NC) system follows. For different distributions, the corresponding calculation methods of MTBF are always different. Undertaken a 2 year period of timing censored test with replacement of NC lathe, authors apply a type I censored likelihood function to make the distribution fitting of time between failures of NC system.

Nowadays, one of the main sources of renewable energy is wind energy; therefore, a wind farm’s electricity system must be effective. As a result, wind farm (WF) equipment must continuously operate without failure or damage. To achieve this, it is necessary to regularly monitor and assess the reliability of WF systems at every point of their “life”, including design, implementation, and continued use.

Abstract:
AbstractTime prediction methods based on monitoring surface displacement (SD) are effective for early warning against shallow landslides. However, failure time prediction by Fukuzono’s original inverse-velocity (INV) method is less accurate due to variation in the inverse-velocity (1/v) caused by noise in the measured SD, which amplifies the fluctuation in the resultant 1/v. Therefore, the present study incorporates pre-analysis to acquire better prediction by reducing the effect of noise on the measured SD. The data extraction (DE) and moving average (MA) methods are used to filter the measured SD for better smoothing of 1/v. The root mean square error (RMSE) and determining factor (f) values are used to select the optimum SD interval (Δx) in the DE method. The RMSE and f values are used to evaluate the reproducibility of the measured data and the scattering in the relationship between velocity and acceleration in an orderly. The data, treated by the DE and MA methods, are utilized to predict the failure time based on the INV method and the relationship between velocity and acceleration on a logarithmic scale (VAA) method. Accordingly, Δx gives the smallest sum of the normalized RMSE and normalized (1-f), which offers a better prediction. When the SD at failure changes, Δx is changed. The best prediction is obtained by DE preprocessing with the VAA method because it minimizes the effect of the individual 1/v by reducing the scatter in the relationship between velocity and acceleration. However, the time prediction using data processed by the MA method shows poor prediction due to some scattering of the inverse velocity. In some cases, the prediction by the VAA method using MA data provides better prediction than the results of the INV method.

Abstract Frequent leaks were observed in the seal flush coolers of pumps in crude distillation unit where shell side is open recirculation cooling water. These coolers are in small size and low value items. However, repeated coil leaks resulted in failure of pump seals (increased maintenance cost) &amp; reduced standby redundancy of the pumps. Moreover, cooling water is often contaminated with hydrocarbon (seal oil media) causing increased wastage of treated water by blowdowns (environmental concern), additional consumption of fresh water &amp; treatment chemicals. Further, there is an increas

Abstract:
Abstract Geothermal resources with temperatures between 250° and 360°F (121° and 182°C) are prime candidates for binary-cycle power generation in the United States and abroad, and constitute about 80% of the known power-capable resources in the United States. Initially there were many technological obstacles to exploitation of these resources, with one of the greatest being the absence of reliable high-capacity downwell brine production pumps to supply the required amounts of brine from an economically small group of wells. Early experience revealed many problems with downwell pumps, resulting

Abstract In many cases, existing corrosion protection methods provide insufficient protection to a myriad selection of metal parts in unpredictable, highly corrosive environmental and application conditions. This includes internal surfaces of mothballed equipment, and large enclosures during storage and shipment for extended periods of time. This paper describes the main properties of new volatile and soluble inhibitors formulations that are recommended for rapid and sustained corrosion protection of internal surfaces of enclosures in industrial environments that can contain: chlorides, acidic

Abstract:
Abstract Temporary coatings in conjunction with cathodic protection (CP) in seawater have been used in this paper for solving the contradiction between big initial current density and small mean current density. The repairing effect of calcareous deposits produced during CP on the coating deterioration areas was studied. The morphology of the formed calcareous deposits has been evaluated through optical microscope and chemical analysis has been performed using Raman spectrum. The changes of cathodic protection current and electrochemical impedance spectroscopy with time were measured to explor

Characteristics for the vintage pipeline system were established in terms of diameter, wall thickness, service conditions, grade and toughness, and pipeline designs typical of this system identified. Analyses to qualify mean-time-between-failure and related inspection intervals were performed for these typical vintage pipelines addressing time-dependent degradation and possible failure due to corrosion, fatigue, and stress corrosion cracking.

Abstract:
Forced by the 1997 Southeast Asian crisis to recognize the external vulnerabilities that openness to volatile capital flows result in and upset over the post-crisis policy responses imposed by the IMF, countries in the sub-region saw the need for a regional financial safety net that can pre-empt or mitigate future crises. At the outset, the aim of the initiative, then led by Japan, was to create a facility or design a mechanism that was independent of the United States and the IMF, since the former was less concerned with vulnerabilities in Asia than it was in Latin America and that the latter

Swiss families between tradition and transformation Since 1950, birth rates in industrialised countries have been falling sharply worldwide. The same applies in Switzerland: 50 years ago, women were still having 2.1 children, but nowadays the statistics show they only have 1.4 children. Does this mean the family is becoming less significant as a key social institution? Could it soon be eradicated? What functions does the family perform today? Our study indicates that it will not. However, it is changing. In a representative survey of the Swiss population and in interviews with experts from var

Latin America spends large amounts of resources on social services, yet its life expectancy and education levels are low compared to other regions with similar levels of income. A key reason is the inherent difficulty of making social services produce efficiently in response to demands and needs.
