Non-determinism of the thread schedule is a well-known problem in concurrent programming. However, other sources of non-determinism exist which cannot be controlled by an application, such as network availability. Testing a program with its communication resources being unavailable is difficult, as it requires a change on the host system, which has to be coordinated with the test suite. Essenti...

in this research, the effects of oxygen injection during the induration process were studied in order to improve the quality specifications and increase the rate of production of the iron oxide pellets. several experiments were carried out in palletizing pilot plant in different conditions of oxygen injection. the results suggested that if only the extra oxygen was injected into the furnace in ...

this study was performed to evaluate the efficacy of injection of essential oil of eugenia caryophyllata in the kid horn buds, as a new chemical technique for disbudding. five-day-old healthy goat kids from both sexes (n = 16) were divided randomly into 4 equal groups. in groups 1, 2 and 3, 0.2 ml of clove essence and in group 4 (control) 0.2 ml of normal saline was injected into the left horn ...

Testing application behavior in the presence of I/O failures is extremely difficult. The resources used for testing usually work without failure. Failures typically cannot be initiated on the test suite level and are usually not tested sufficiently. Essentially, each interaction of the application with the environment can result in a failure, making failures hard to test. The Enforcer tool iden...

This paper turns the concept of input distributions on its head to exploit inverse input distributions Al though such distributions are not always true math ematical inverses they do capture an intuitive prop erty inputs that have high frequencies in the original distribution will have low frequencies in the inverse distribution and vice versa We can use the inverse distribution in several di e...

In the design of measurement systems we face the fact that parameters are subject to (measurement-) uncertainties. Additionally, components may behave entirely different from what is specified, which is then considered a fault. Consequently, both uncertainty as well as probability of failure should be considered in education on robust design and reliability. In this paper we present a teaching ...

abstract background: providing better surgical conditions with meticulous control of intraocular pressure (iop) is one of the most important factors that affect the success rate in ophthalmic surgery. clonidine is a selective central α2 agonist with analgesic, antianxiety and sedative effects which makes it a good choice in premedication recently. in this study, we compared the effects of oral ...

This paper aims at validating the efficiency of a fault injection approach to predict error rate on applications devoted to operate in radiation environment. Soft error injection experiments and radiation ground testing were performed on software modules using a digital board built on a digital signal processor which is included in a satellite instrument. The analysis of experimental results pu...

background: the purpose of dehorning in cattles is to decrease injuries and increase security in farms. besides breeding managements, different chemical and physical methods are used for dehorning of livestock, depending on their age, each of which has advantages and disadvantages. objectives: this study was performed to evaluate the effects of clove oil on disbudding new born calves following ...
