Construction project cost overrun is a common problem in the construction industry. The of projects thought to have increased by approximately 33% on average. Several types research been conducted and these generally rely historical data. However, whilst each has its own characteristics trend, real-time data are more reliable forecast trend. This paper proposes hidden Markov chain (HMM) model p...

In building construction projects there are 3 factors that used to measure project performance, one of which is cost. Efforts can be made minimize the cost overrun knowing causative and how mitigate them. The purpose this study identify factors, determine dominant causing overrun, efforts methodology in research desk or uses relevant secondary data analysis, such as previous with similar proble...

Creating secure software applications and writing secure programs are difficult affairs. Secure programs are well designed software applications which meet specified requirements. Well designed software is reliable in its availability and accessibility. The paper’s problem is whether the textbooks used in instruction of beginning programming students directly and actively discuss secure program...

Cost overrun of software projects is major cause of their failures. In order to facilitate accurate software cost estimation, there are several metrics, tools and datasets. In this paper, we evaluate and compare different metrics and datasets in terms of similarities and differences of involved software attributes. These metrics forecast project cost estimations based on different software attr...

For many real-time embedded systems, Time-Triggered Co-operative (TTC) scheduling algorithms provide simple and reliable solution at low cost. Previous work in this area has focused on the development of a wide range of TTC implementations for various purposes (e.g. for achieving low-jitter characteristics, reducing CPU power consumption or dealing with task-overruns). Despite the great deal of...

We present the design, implementation, and experimental results of our soft real time (SRT) system for multimedia applications in a general purpose UNIX environment. The SRT system supports several service classes for the real time processes based on their processor usage time pattern: periodic constant processing time(PCPT) class, aperiodic constant processing time(ACPT) class, variable proces...

Mixed-Criticality systems are arising due to the push from several major industries including avionics and automotive, where functionalities with different safety criticality levels are integrated into a modern computing platform to reduce size, weight and energy. The state-of-the-art research has focused on protecting critical tasks under the threat of task overrun, which is achieved by killin...

December 3, 1967. Exactly fifty years ago. The world was stunned by the news that the first successful heart transplantation had been performed at the Groote Schuur Hospital in Cape Town, South Africa, by a then little known surgeon, Christiaan Neethling Barnard. The heart of a young woman, Denise Darvall, who was overrun by a car in a city, was implanted in the chest of a 54-year old patient d...

Many western grasslands and scrublands are being overrun by Mediterranean annual grasses that are a limiting impediment to grassland restoration throughout the western United States (Kay et al. 1981; Dyer and Rice 1997, 1999; Brown and Rice 2000). Conserving and restoring these invaded ecosystems are important biodiversity goals. Restoring perennial grasslands can also increase the forage quali...

Globally, power projects are prone to cost overrun projects. Within the body of knowledge, previous studies have paid less attention predicting overruns assist contingency planning. Particularly, in thermal plant (TPPPs), enormous risks involved their delivery undermine accuracy prediction. To prevent projects, these need be accounted for by employing sophisticated prediction techniques. This s...
