Power Grid Infrastructural Resilience against Extreme Events
Extreme weather events are one of the main causes of large-scale power outages in distribution systems. The changing climate has led to an increase in the frequency and severity of these events, which, if not mitigated, are expected to lead to more instances of widespread outages and the severe societal and economic damages that ensue. Protecting the power grid against such events, which are high impact yet low frequency, requires a paradigm shift in grid design practices.

Combined Heat and Power-Based Microgrids
The microgrid has emerged to reduce centralized generation problems and make structural changes to power systems. Parallel operation of distributed generation (DG) units, combined heat and power (CHP) units, and energy storage in the microgrids reduces environmental pollution, operation costs, and increases the reliability of energy systems.

Decoupling Recurrent Neural Networks in Training and Testing
Recurrent neural networks (RNN) have been shown to outperform other architectures when processing temporally correlated data, such as from wireless communication signals. However, traditional usage assumes a fixed observation interval during both training and testing despite the sample-by-sample processing capabilities of RNNs. Rather than assuming that the testing and observation intervals are equivalent, the observation intervals can be “decoupled" or set independently. This opens the door for processing variable sequence lengths in inference  by defining a decision criteria. "Decoupling" can potentially reduce training times and will allow for trained networks to be adapted to different applications without retraining -- including applications in which the sequence length of the signal of interest may be unknown.

Architecture-Level Optimization on Silicon Photomultipliers
Sensors based on single-photon avalanche diodes (SPADs) are nowadays employed in a wide variety of single-photon counting and fast-timing applications, e.g., high-energy physics; time of flight (TOF) ranging and 3D imaging; Raman spectroscopy; and bio-medicine, including fluorescence-lifetime imaging microscopy and positron emission tomography (PET), to name a few. SiPMs are the most common sensors in PET applications, where they detect the light produced by the interaction between gamma photons and scintillator crystals.

Industrial Microgrids Based on Renewable Energy
Electric microgrids based mainly on renewable energies have seen a big expansion due to the great advantages they present against fossil fuels. Nowadays different governments are becoming aware of the use of environmentally friendly energies, so progressive investment has been granted to the consumers in Spain. It should be noted that in applications using renewable energies, the use of energy storage systems (ESS) has been implemented with the aim of improving the reliability of the system to avoid the intermittent nature of energy generation. Most of these ESS use lithium-ion batteries and sodium–sulfur batteries having high power and energy densities and high efficiency. Many industrial activities are gradually giving an opportunity to this type of MG system of renewable energy (RE) with EES.

Unisys ICON
The ICON was a computer built specifically for use in schools, to fill a standard created by the Ontario Ministry of Education. It was based on the Intel 80186 CPU and ran an early version of QNX, a Unix-like operating system. The system was packaged as an all-in-one machine similar to the Commodore PET, and included a trackball for mouse-like control. Over time a number of GUI-like systems appeared for the platform, based on the system's NAPLPS-based graphics system. The ICON was widely used, mostly in high schools in the mid to late 1980s, but disappeared after that time with the widespread introduction of PCs and Apple Macintoshes. They were also known as the CEMCorp ICON, Burroughs ICON, and finally Unisys ICON when Burroughs and Sperry Corporation merged to form Unisys in 1986. The machine was also nicknamed the bionic beaver.

The Implementation of Precise Point Positioning
High-precision positioning from Global Navigation Satellite Systems (GNSS) has garnered increased interest due to growing demand in various applications, like autonomous car navigation and precision agriculture. Precise Point Positioning (PPP) offers a distinct advantage over differential techniques by enabling precise position determination of a GNSS rover receiver through the use of external corrections sourced from either the Internet or dedicated correction satellites. However, PPP’s implementation has been challenging due to the need to mitigate numerous GNSS error sources, many of which are eliminated in differential techniques such as Real-Time Kinematics (RTK) or overlooked in Standard Point Positioning (SPP).

Plasmonic Circuitry
Plasmonics is the study of plasmons, quasiparticles of plasma oscillation in solids such as metals, semi-metals, metal oxides, nitrides, doped semiconductors, etc. An effort is currently being made to implement plasmons in electric circuits, or in an electric circuit analog, to combine the size efficiency of electronics with the data capacity of photonic integrated circuits. Plasmonics can be understood as "light-on-metal-dielectric-interfaces," where electrons oscillate at the surface of a metal due to strong resonant interactions with the electric field of incident light. Due to the high scattering rate of electrons, ohmic losses in plasmonic signals are generally large, which limits the signal transfer distances to the sub-centimeter range, unless hybrid optoplasmonic light guiding networks, or plasmon gain amplification are used. Both surface plasmon polaritons propagating along the metal-dielectric interfaces and localized surface plasmon modes supported by metal nanoparticles are characterized by large momentum values, which enable strong resonant enhancement of the local density of photon states, and can be utilized to enhance weak optical effects of opto-electronic devices.

Community Connected Microgrids
Renewable energy systems in the form of community microgrids, and grid-connected solar PV-storage are considered primary solutions for powering residential developments. The primary objectives for commissioning such systems include significant electricity cost reductions and carbon emissions abatement. Despite the proliferation of renewables, the uptake of solar and battery storage systems in communities and multi-residential buildings are less researched in the literature, and many uncertainties remain in terms of providing an optimal solution.
