The energy hub is considered one of the most important parts multi-carrier distribution systems. One major challenges facing idea optimal and management based on renewable non-renewable power generation resources in presence demand response programs uncertainties. This study aims to present an model uncertainties probability modelling resources, electrical loads (electric vehicles (EVs)), opera...

Service industries, such as ports, are attentive to their standards, a smooth service flow and economic viability. Cost benefit analysis has proven itself as a useful tool to support this type of decision making; it has been used by businesses and governmental agencies for many years. In this book chapter we demonstrate different modelling methods that are used for estimating input factors requ...

This paper presents a novel freeform surface modeling method to construct a freeform surface from 3D sketch. The approach is inspired by Newton’s universal attraction force law to construct a surface model from rough boundary curves and unorganized interior characteristic curves which may cross the boundary curves or not. Based on these unorganized curves, an initial surface can be obtained for...

In this paper, we present novel techniques to modify freeform shapes defined by implicit algebraic models. These models are first simplified by introducing a decomposition in terms of conic-line primitives and then the desired local/global shape changes are produced by varying the parameters of these primitives. A decomposed model provides efficient control of each primitive using its canonical...

This paper proposes an Optimal Power Flow (OPF) algorithm by Direct Load Control (DLC) programs to optimize the operational cost of smart grids considering various scenarios based on different constraints. The cost function includes active power production cost of available power sources and a novel flexible load curtailment cost associated with DLC programs. The load curtailment cost is based ...

This paper focuses on multilayer perceptron neural networks where the activation functions are adaptive and where each neuron synapse is modelled by a finite impulse response (FIR) filter. A simplified architecture consisting of a variable activation (VA) function which is sandwiched between two FIR synapses is studied. The VA function consists of a mixed linear-tanh sigmoid with a parameter wh...

Ontario (Canada) Health System stakeholders support the idea and necessity of the integrated source of data that would include both clinical (e.g. diagnosis, intervention, length of stay, case mix group) and financial (e.g. cost per weighted case, cost per diem) characteristics of the Ontario healthcare system activities at the patient-specific level. At present, the actual patient-level case c...

There is an urgent need to formalize Activity-Based Costing (ABC) for purposes of implementation and usage in enterprises so that enterprises have access to the critical element of global success, viz., strategic management accounting. To make this possible, the authors present a core cost ontology and micro-theory of costing for enterprise modelling that spans the knowledge representation of a...
