"Construction project complexity: critical project characteristic that project managers must manage to deliver successful projects"
Baccarini (1996) opined that construction’s complexity has inherent dynamic nature which determines plan, coordination, collaborative undertakings, performance, and control requirements. It is inclusive of interrelated parts which can be operationalized based on (a) differentiation, e. nature of tasks along with needed specialists, and (b) interdependence of elements, work plans, and workers who are expected to systematically contribute to the success of project implementation

Green housing and construction in Greece
Building and construction industry can cause negative impact on the environment in many ways, particularly when the planned construction is in a way causing the poor utilization and wastage of land, energy and resources. According to Glavinich (2008) the current construction methods are utilizing non-renewable resources which prove them lethal to the environment right from the source of extraction to the creation of the harmful materials and the transportation of these materials in long

Compare rigidising methods using re enforced material (carbon fibres and glass fibres embedded in polymers material) to increase payload capability you have to present figures (numerical facts) and graphs and compare their electricity properties as well
This resistivity further increased after the filler incorporation [4]. This implies that the thermal conductivity of the material increased after subjecting the material to the two treatments. It was also noted that increasing curing pressure increases the through-thickness thermal conductivity more that the filler incorporation. The experiment revealed that the optimum through-thickness thermal conductivity achieved through the process was 1.5 W/m K. The highest ever recorded value for this

Climate change and hydraulic impacts on water networks supply.
In terms of their context, the parameters of climate change can be highly differentiated. In fact, it seems that each time that climate changes need to be assessed the parameters used need to vary according to the characteristics of the region, as of its geography, and the information available (Van Dam 2003, p. Of course, there are certain parameters that are necessarily used when evaluating climate changes worldwide. The level of CO2 emissions or the annual average volume of waste can be

Coding Schemes in Optical Fibre, Dicode Pulse Position Modulation, Reed Solomon Code, and FPGA
Optical communications based on free-space are significantly affected through changing atmospheric conditions (Acton, 2011). Researchers have been sincerely interested in learning about the performance of higher order multiple pulse position modulation over highly dispersive optical channels. This is performed through the use of different slots of the PPM system on the channel of the plastic optical fiber. The analysis of the process can be done with the use of a software solution as otherwise

Conduct a literature review and summarize the historical development of the equations used for design of cfa piles in granular soils
This is evident in the book Numerical modelling of soil-pile axial load transfer mechanisms in granular soils by Aguiar, Sofia, and Arézou Modaressi. For this case, the formula for the total side-shear resistance is: RS = fs-ave π D L where D is for the average diameter of the pile, and L represents the pile total embedment length. On the other hand, the formula for total end-bearing resistance is: RB=qp[πDB2] where qp stands for the unit end-bearing resistance, and DB stands for the

There is a corresponding increase in acceleration and fuel consumption as well. There is a minor spike in fuel consumption during the initial idling regime but this may be considered as an outlier. The vehicle is then braked around t = 40 seconds and allowed to come to a rest. Here, the acceleration enters a negative regime while the fuel consumption decreases, but does not go to zero since the engine is still running. In comparison, NEDC requires an idling time of 40 seconds before moving the

Is Building Information Modelling (BIM) successfully delivering time and cost benefits?
One of the main advantages of BIM is that it reduces rework (Epstein, 2012). This is because; it is able to calculate with high levels of accuracy the exact amount of resources and materials that will be used and hence there is less wastage in the various processes. This enables work to be done instantaneously and, therefore, eliminates the need for reworks. It improves productivity. Through the information that is generated by this technology, it is able to calculate the exact amount of

Factory Extension
More often than not, offsite manufacturing, also known as modular manufacturing is preferred in instances where emphasis is on ensuring minimal or no impact is desired within the existing facilities or in instances where the company’s facilities is stretched and hence no room for intensive construction works. However, more and more corporations are adopting modular construction over onsite manufacturing in construction of factory extensions.Oicho (2011) reported that benefits of modular

Cobalt addition results in increased red hardness, which makes tools applicable for use at higher temperature during operation. Manganese helps the tool steel in quick hardening, while going through heat treatment process. Larger addition of this element, between 1.2 to 1.6 percentages enables the steel to quench in oil instead of water, while lowering the quenching temperature, meant for hardening the tool steel. Molybdenum also helps in lowering this temperature and this element helps in

Heat transfer across a porous media (Laminar Flow across a porous media)
Streamline flows refer to the same reality of laminar flows, and in such flows, there is a regularity and constancy in the flow properties of a fluid along every point in that fluid, including the pressure and the speed/velocity of the fluid. Laminae refer to layers of water, very thin, that are imagined as constitutive of fluid flows along a horizontal path for instance. The laminae are imagined to all slide from one another to create flow, in the same way that a card deck flows horizontally
