Communication plans are intrinsic to project management. However, the time and cost effects of communication plan choices have largely been overlooked. Herein, we study the impact of three types of communications plans that implement collaborative information technologies (CITs) (i.e., asynchronous, synchronous and both) on the key project metrics of communication cost and project schedule perf...

Throughout the design of automotive vehicle systems, modeling and simulation technologies have been widely used for supporting their conceptualization and evaluation. Due to the increasing complexity of such systems, the overall quality management and design process optimization are becoming more important. This in particular brings the necessity of integrating various domain-specific physical ...

In this paper, a dynamical multiple criteria model of integrated adaptive planning and scheduling for complex technical – organizational system (CTOS) is presented. Various types of CTOS are used nowadays, for example: virtual enterprises, supply chains, telecommunication systems, etc. Hereafter, we mostly interpret CTOS as the systems of the above-mentioned types. The above-mentioned CTOS pecu...

Parametric images can help investigate disease mechanisms and vital functions. To estimate parametric images, it is necessary to obtain the tissue time activity curves (tTACs), which express temporal changes of tracer activity in human tissue. In general, the tTACs are calculated from each voxel’s value of the time sequential PET images estimated from dynamic PET data. Recently, spatio-temporal...

today, one of the new technologies in the modern era is vehicular ad-hoc network which has takenenormous attention in the recent years. because of rapid topology changing and frequent disconnectionmakes it difficult to design an efficient routing protocol for routing data between vehicles, called v2v orvehicle to vehicle communication and vehicle to roadside infrastructure, called v2i. designin...

A sustainability technology evaluation platform has been prototyped for simulating integrated technology systems within a specific urban regional context. ‘‘Sustainability technologies’’ refer to available and potentially available technologies that may help to decrease human pressures on the environment or natural resources while providing a desired standard of living. The platform is based on...

Many long-span bridges have been built throughout the world in recent years but they are often subject to multiple types of dynamic loads, especially those located in wind-prone regions and carrying both trains and road vehicles. To ensure the safety and functionality of these bridges, dynamic responses of long-span bridges are often required for bridge assessment. Given that there are several ...

It is necessary to introduce some optical concepts before discuss about the different applications of adaptive optics (AO) in human vision. Wave aberration1 is defined as the difference between the perfect (spherical) and the actual wavefront (WF) for each point over the pupil. Figure 1 shows this concept schematically. AO may be defined as an optical system which adapts to compensate aberratio...

As semiconductor lithography is pushed to smaller dimensions, process yields tend to suffer due to subwavelength topographical imaging effects. Three dimensional or “thick mask” effects result in such things as a pitch dependent best focus and, for alternating phase shift masks (AltPSMs), an intensity imbalance between etched and un-etched features. Corrective mask structures such as the dual t...
