abstract intensive and inefficient use of energy leads to degradation of natural resources and environmental problems. this study evaluated the relationship between the energy of consumed inputs and yield of tomato, cucumber and melon using the cobb–douglas production function. the data were collected from 90 farmers in firoozabad using a questionnaire. the farmers were chosen by simple random ...

Abstract The ever increasing demand for container transportation has led to the congestion of maritime terminals in world. In this work, two interrelated problems berth and quay crane scheduling are considered an integrated multiobjective mathematical model. A special character model is that arrival times vessels failure (working) cranes not deterministic can vary based on some scenarios. Hence...

One of the primary modes for worldwide trade of goods is maritime transport, which is exposed to rapid growth. In order to handle the increase of the traffic in ports, optimization of port operations has been studied and implemented in the past. In container terminals, significant amount of work has been done in the field of large scale optimization. In published literature, the main focus lies...

This paper sketches the concept of haptic-multimodal coupling between operator, coautomation, base system and environment. Haptic-multimodal couplings use mainly the haptic interaction resource, e.g. the combination of hands and feet with active inceptors like active sidesticks or steering wheels, and complement this with e.g. visual and acoustic feedback. Haptic-multimodal couplings can serve ...

Vessel berthing in a container port is considered as one of the most important application systems in the shipping industry. The objective of the vessel planning application system is to determine a suitable berth guaranteeing high vessel productivity. This is regarded as a very complex dynamic application, which can vastly benefited from autonomous decision making capabilities. On the other ha...

Influenza causes substantial illness and loss of work days among young adults, and outbreaks can affect the preparedness of military units. In an influenza pandemic, people who live in confined settings have greater risk of infection. Military trainees are at particularly high risk. Because of likely unavailability of vaccines and antiviral drugs at the start of a pandemic and for many months t...

We consider a terminal operator, who provides his logistics services of container handling at multiple terminals within the same port. In this setting, the well-known berth allocation problem can no longer be considered per terminal for two main reasons: i) vessel calls should be spread over the various terminals to avoid peaks and troughs in quay crane utilizations, ii) an allocation of two co...
