We consider a model of occupational choice in large economies where individuals differ in their wealth endowment. Individuals can remain self-employed or engage in productive matches with another individual, i.e., form firms. Matches are subject to a moral hazard problem with limited liability. The division of the gains from such matches is determined by competitive forces. When the incentive p...

Increasing amounts of local power generation and loads are challenging the management of low voltage (LV) grids. This paper proposes a low voltage grid monitoring and control solution enabling a grid operator to: 1) assess available capacity in an LV grid for planning purposes, 2) provide grid constrained electrical vehicle (EV) charging control, and 3) optimize the injection of photovoltaic (P...

Due to limitations on the supply and availability of fossil fuels and the need to reduce environmentally damaging emissions, the Irish government is attempting to increase the market share of electric vehicles (EVs) to a target of 10% by 2020 whilst also increasing the proportion of renewable energy generation. This paper uses data collected from household charge points in Ireland to analyse ex...

An electrically bistable device has been fabricated based on poly(N-vinylcarbazole) (PVK)-silver sulfide (Ag2S) composite films using a simple spin-coating method. Current-voltage (I-V) characteristics of the as-fabricated devices exhibit a typical electrical bistability and negative differential resistance (NDR) effect. The NDR effect can be tuned by varying the positive charging voltage and t...

Experimental studies of bioelectric effects caused by single intense, ultrashort (nanosecond and even subnanosecond), square wave pulses indicate that the product of electric field amplitude and pulse duration, i.e., the electrical impulse, can be considered a similarity or scaling factor. An explanation for this scaling law is based on the assumption that any bioelectric effect in this paramet...

Recent advances in the type and variety of sensing technologies have led to an extraordinary growth in the volume of data being produced, and led to a number of streaming applications that make use of this data. Sensors typically monitor environmental or physical phenomenon at pre-defined time intervals or triggered by user defined events. Understanding how such streaming content (the raw data ...

Novel, networked information-rich control systems are emerging to provide a stable and cost-efficient operation of future electricity distribution grids. However, the dependence on fault-prone, low-cost, and heterogeneous network technologies and architectures challenges the grid control quality. In this work, we study the impact of varying network QoS on the low voltage grid operation in an el...

This paper presents a formulation of unit commitment for thermal units integrated with wind and solar energy systems and electrical vehicles with emphasizing on Mixed Integer Nonlinear Programming (MINLP). The renewable energy resources are included in this model due to their low electricity cost and positive effect on environment. As well as, coordinated charging strategy of electrical vehicle...

The battery charging system is a critical part of a plug-in hybrid electric vehicle (PHEV). The efficiency, charging speed, and cost of such chargers are crucial to the commercialisation of PHEVs. In this paper, the advantages and drawbacks of four potential PHEV charger topologies were compared based on their operations through simulation and experiments. Their electrical stress, efficiency, c...

A porphyrin-silicon nanowire (Si-NW) hybrid field-effect transistor is introduced. The hybrid device has separate electrical and optical gates surrounding the Si-NW channel. Porphyrin, a component of chlorophyll, is employed as an optical gate to modulate the potential of the Si-NW channel. Due to the independently formed hybrid gates, both optical and electrical excitation can effectively modu...
