The probability of schedule overruns for construction and engineering projects can be ascertained using a ‘best fit’ probability distribution from an empirical distribution. The statistical characteristics of schedule overruns occurring in 276 Australian construction and engineering projects were analysed. Skewness and kurtosis values revealed that schedule overruns are non-Gaussian. Theoretica...

Software Effort Estimation is the process of estimating the effort required to develop software. By estimating the effort, the cost and schedule required to estimate the software can be determined. Accurate Estimate helps the developer to allocate the resource accordingly in order to avoid cost overrun and schedule overrun. Several methods are available in order to estimate the effort among whi...

Nowadays projects are more complicated involving huge contract values, participants from multi-discipline, more specialized works, tighter schedule, stringent quality standards, etc. Ultimately, cost and time are the two key parameters that plays significant role in a project success. The study focuses on multiple Design and Build (D&B) project which has complicated risk and is governed by fixe...

The aim of this research was to evaluate the changes in the Gelato ice cream properties at different levels of sweet whey protein concentrate (WPC) substitutions of egg yolk. Samples were made with two levels of egg yolk (4.5 and 9%). For each level one control sample with no WPC addition and four levels of WPC substitutions (20, 50, 80 and 100%) were made. Three replications of each treatment ...

This paper studies the use of sensitivities to quantify the extent to which individual airline departments (stakeholders) contribute to the incident of runway overrun. For that purpose, we present a model of the incident runway overrun. The incident model is based on the dynamics of aircraft and describes the functional relationship between contributing factors leading to the incident. The inci...

This paper presents the results of studies concerned with the preparation of fresh food foams based on egg white and various hydrocolloids including Iranian gum tragacanth, guar and xanthan gums at different concentrations (0.002-0.040% w/w). The basic physical parameters of the obtained foams such as overrun, stability and morphology of gas bubbles were measured. Viscosity measurements were al...

Currently, attention of the aviation community and authorities is being increasingly focused on flight safety in landing phase. It accounted for increased frequency incidents final phase significant threats associated with consequences these events. The statistics accidents reveals that from 1959 to 2019, 55% aircraft crashes world occurred phases takeoff. given resulted 51% all fatalities boar...

A common assumption for scheduling mixedcriticality systems is the degradation of less critical tasks when the system is in the emergency mode; which is entered when critical tasks overrun their expected WCET. In the meanwhile, common safety standards enforce strict safety requirements on all criticality levels. However, the impact of degrading less critical tasks on the overall system safety i...
