The envisaged method of dynamic energy-capacity planning is based on dynamic energy consumption distribution (DECD) capabilities of Smart Microgrids. Such capabilities can be achieved by implementation of Internet of Things (IoT) sensors fusion and optimized communication networks in an Advanced Metering Infrastructure (AMI). This method is described by the mathematical model for DECD that has been...
The ongoing enhancement of Advanced Metering Infrastructure (AMI) is a key factor in improving the development and efficiency of current Microgrids (MGs). The main fundamental technologies driving AMI are the newest generation of Smart Meters (SMs) and the implementation of Internet of Things (IoT) sensors in appliances. Both of these technological innovations enable the design of an AMI with dynamic...
With the implementation of IoT intelligent sensors, broadband communication networks are important requirement for the emerging advanced Smart Metering Infrastructure (SMI) and future enhancement of Smart Grids. Passive Optical Networks (PONs) are the main technology implemented in current Wide Access Area Networks of SMI. Data transmission delays and security issues in PON have certain difficulties...
Cloud computing is getting increased attention of the information and communication technologies (ICT) industry recently. The cloud service providers foresee it as a source of promising financial gains, the clients find it a convenient solution where the enterprises may get started on their computing activities without investing on the in-house facilities of hardware and software. They can outsource...
The optimization of InGaN/GaN multiquantum wells structure based on Si-doped GaN substrate for λ~445 nm is performed. Advance simulation for a self-consistent laser model combined with band-structure and free-carrier gain calculations is employed to study effects such as waveguiding, carrier transport and heat flux. Enhancement in output power of the optimized structure is calculated. It...
In the access part of the network, passive optical networks (PON) are the top priority due to their robustness and large data carrying capacity. The customer premises equipment consumes 65% of the total power. We propose a cross layer model for saving energy in the optical network units (ONU). Our solution involves analysis of TCP traffic by extracting session information from the traffic and determining...
Thin film GaN growth on c-plane sapphire (0001) substrate using two-step method by nitrogen plasma assisted MBE is reported. After growth optimization, a low temperature buffer layer was grown followed by the main GaN thin film. The Optical and structural properties of the film were investigated using XRD, Raman spectroscopy, Photospectrometry and in-Situ RHEED. The polycrystalline nature of the grown...
We have investigated the transient thermal behavior and heat distribution in a multi-quantum wells (MQWs) InGaN/GaN lasers diode for λ~445 nm based on GaN substrate. 2D thermal modeling was performed to estimate the dissipation of heat from the active region. Different thermal designs for planner and solder ball bumps packages have been studied using Al2O3, ceramic-AlN and SiC as submount...
Qualitative optimization of the InAlN as electron-block layer (EBL) has been studied. Analytical comparisons of AlGaN and modified InAlN as EBLs have been performed. Using 2D simulation, significant improvement in the emission intensity of the designed structures with In0.18Al0.82N EBLs compared to similar with non-EBL and Al0.8Ga0.82N as EBL is observed. This enhancement can be attributed to the...
