The Shanker distribution, a one-parameter lifetime distribution with an increasing hazard rate function, is recommended by for modelling lifespan data. In this study, we examine the theoretical and practical implications of 2-component mixture model (2-CMSM). A significant feature proposed model’s function that it has rising, decreasing, upside-down bathtub forms. We investigate statistical cha...

reactivity controlled compression ignition (rcci) is a novel combustion concept which uses port fuel injection (pfi) of a low reactivity fuel and direct injection (di) of a high reactivity fuel with optimum multiple injection to provide a stratified mixture inside the combustion chamber. piston bowl design has a considerable effect on engine’s pollutant emissions specially unburned hydrocarbons...

Functionally impaired people always have difficulty accomplishing activities of daily living. In this regard, tasks including toileting and bathing a higher prevalence rate injuries greater risk falling. study, body-transfer wheelchair was developed to assist in transferring from bed for bathing, toileting. The is semi-automatic that has features such as controlled leg backrest, linkage commode...

In the standard economic models of traffic congestion, traffic flow does not fall under heavily congested conditions. But this is counter to experience, especially in the downtown areas of most major cities during rush hour. This paper presents a bathtub model of traffic congestion. The height of water in the bathtub corresponds to traffic density, velocity is negatively related to density, and...

The objective of our study was to determine if rural residence was associated with an increased risk of drowning in Ontario, Canada. We conducted a retrospective cohort study of all unintentional drowning deaths in Ontario, Canada from 2004 to 2008. Age-adjusted mortality rates for males and females living in rural and nonrural areas were calculated using direct standardization, with non-rural ...

In this paper a new four-parameter lifetime distribution named “the Exponentiated gompertz-poisson (E-GP) distribution” has been suggested that it has a decreasing, increasing, bathtub-shaped and inverse bathtub-shape for modeling lifetime data. The Exponentiated gompertz-poisson has applications in economics, actuarial modelling,reliability modeling, lifetime and queuing problems and biologica...

One puzzling aspect of the present perfect is that temporal adverbials are sometimes acceptable in a present perfect sentence and sometimes not, as illustrated by the examples below: (1) a. Martha has lived in Boston for ve years. b. For ve years Martha has lived in Boston. (2) a. Chris has left at midnight. b. #At midnight Chris has left. (3) a. John has been in the bathtub until noon. b. #Unt...

We present experiments and theory for the "bathtub vortex," which forms when a fluid drains out of a rotating cylindrical container through a small drain hole. The fast down-flow is found to be confined to a narrow and rapidly rotating "drainpipe" from the free surface down to the drain hole. Surrounding this drainpipe is a region with slow upward flow generated by the Ekman layer at the bottom...

The zero-truncated Poisson distribution (ZTPD) generates a statistical model that could be appropriate when observations begin once at least one event occurs. intervened (IPD) is substitute for the ZTPD, in which some intervention processes may change mean of rare events. These two distributions exhibit underdispersion (i.e., their variance less than mean). In this research, we offer an alterna...

A simply curved Weibull plot means that the studied data set has a three-parameter distribution with non-zero location parameter representing lower or upper limit of set. This paper introduces four-parameter both these limits can be applied in reliability and materials engineering. very reliable indicator this is double-curved plot. The great advantage fact corresponding hazard rate curve batht...
