power transformers are important equipments in power systems. thus there is a large number of researches devoted of power transformers. however, there is still a demand for future investigations, especially in the field of diagnosis of transformer failures. in order to fulfill the demand, the first part reports a study case in which four main types of failures on the active part are investigate...
The expectation of a random variable is its average value, where each value is weighted according to the probability that it comes up. The expectation is also called the expected value or the mean of the random variable. For example, suppose we select a student uniformly at random from the class, and let R be the student’s quiz score. Then E [R] is just the class average —the first thing everyo...
• A submitted manuscript is the author's version of the article upon submission and before peer-review. There can be important differences between the submitted version and the official published version of record. People interested in the research are advised to contact the author for the final version of the publication, or visit the DOI to the publisher's website. • The final author version ...
conventional implant dentistry has been limited to healed edentulous ridges with adequate bone. predictable success rates resulted in using dental implants in compromised situations such as insertion into old infected sites or near to pathological areas. there is significant data about marginal bone loss and lack of osseointegration around the neck of implants. however, the data about peri apic...
head trauma associated with multiple destructive cognitive symptoms. cognitive destruction leads to impairment in cognitive tasks and cognitive failure. cognitive failures include problems with memory, attention, and operation. this study aimed to comparing cognitive failures in mild traumatic brain injury (tbi) patients and normal people in kashan. the study was performed on 40 tbi patients re...
The translation of Digital products applicable to military application has been affected by the DoD's need for lower cost products. Products developed for military application must retain robust mechanical characteristics; however, each product may be tailored to meet government specifications such as mean time between failure and temperature range. Design changes for military use have had a be...
In a previous paper Low91] we presented two new models of timed CSP. The rst model included biased operators in the syntax, which could be used to model diierent priorities on actions. The second model extended this by adding a probabilistic choice operator to the syntax; this allowed us to give a semantics which modelled the probabilities of diierent behaviours occurring. In Low92b] we present...
In order to create more comfortable and energy saving living spaces, we have to investigate what is comfortable and how to measure comfort of users in a living space. Some measures of thermal comfort have been defined as Predicted Mean Vote (PMV) and Predicted Percentage Dissatisfied (PPD) as an international standard. However, complex and high cost equipments are required to measure PMV by con...
