LPWAN
LPWAN stands for Low Power Wide Area Network;  LPWAN provides long-distance communication for rural and urban areas to support IIoT devices considered by a ten-year provision time to acclimate IIoT applications with higher extensibility, availability of intelligent monitoring infrastructure for a small portion of data exchanges. LoRa is favorable to use with smart sensing applications working IIoT non-authored spectrum. NBIoT is suitable for supporting agriculture and environmental data collection and observations, industrial data tracking and monitoring, inventory tracking, smart billing, and smart buildings, smart metering, and smart cities. Machine-to-machine (M2M) communication uses the Bluetooth Low Energy (BLE) technique for the data communication, the other IIoT applications used in healthcare, smart agriculture, intelligent home, smart vehicles, smart city, smart gadgets, and industries use the cognitive LPWAN, LoRA, Sigfox.  There is a need to mix most LPWAN technologies in heterogeneous IIoT applications to provide more efficient and convenient intelligent services. In heterogeneous IIoT applications, there a need to mix most LPWAN technologies to provide more efficient and convenient intelligent services. This will be deployed by cognitive LPWAN

Air Nautique
The Super Air Nautique line-up of Nautique Boats is Correct Craft's crossover-wakeboarding focused model; the boat is outfitted for wakeboarding with a tower and ballast tanks from the factory. Furthermore, some Super Air Nautiques are in V-drive format, which creates a bigger wake for the rider. The first Air Nautique was built in 1997; it was built on the existing Sport Nautique Hull and had an automatic rear ballast system (Launch Control System or "LCS"). Other notable "landmarks" included Correct Craft's patented "Flight Control Tower", which was essentially a modified fishing tower. In 2019 Nautique released the Super Air Nautique G23 Paragon, this new release is the most expensive boat Nautique has created and is aimed at being the most luxurious experience on the water. In 2013 the Super Air Nautique has moved from being primarily for wakeboarding but now also wakesurfing. This has come with the addition of wake-plates located on the stern of the boat and ventilation systems that direct the exhaust into the propeller jet stream. The new features that Nautique has added is known as the Nautique Surf System (NSS).

Innovation Capacity in Developing Countries
Innovation is an intrinsic capacity of humankind, enabling the adaptation to changes and managing probable solutions to problems regarding its welfare or its surroundings. It constitutes a key driver of sustainable growth. Moreover, innovation capacity is among the dynamic capacities leading to achieving a competitive and sustainable advantage. Hence, by adopting innovative and R&D practices, a country might enhance its growth and competitiveness, particularly for a developing country. In addition, it encompasses diverse perspectives, e.g., organizational capacity, public capacity, regional capacity, national capacity, among others. Therefore, many public and private organizations have focused their efforts on identifying and quantifying the variables that determine the innovation capacity of a country. Various mechanisms have been proposed to assess this capacity, such as the national innovation capacity, Global Innovation Index (GII), Global Competitive Index (GCI) , or European Innovation Scoreboard (EIS). These mechanisms aim at providing an objective measurement of the performance of a country regarding innovation capacity or innovation as a means to competitiveness. Each one of these presents a particular set of determinants, methods, and interpretations to assess innovation.

Time Series Aggregation for ESMs
Due to the high degree of intermittency of renewable energy sources and the growing interdependences amongst formerly separated energy pathways, the modeling of adequate energy systems is crucial to evaluate existing energy systems and to forecast viable future ones. However, this corresponds to the rising complexity of energy system models (ESMs) and often results in computationally intractable programs. To overcome this problem, time series aggregation is frequently used to reduce ESM complexity. As these methods aim at the reduction of input data and preserving the main information about the time series, but are not based on mathematically equivalent transformations, the performance of each method depends on the justifiability of its assumptions.

Chemical Rings
The epoxidized group, also known as the oxirane group, can be considered as one of the most crucial rings in chemistry. Due to the high ring strain and the polarization of the C–O bond in this three-membered ring, several reactions can be carried out. One can see such a functional group as a crucial intermediate in fuels, polymers, materials, fine chemistry, etc.

MEMS Inertial Switches
An exhaustive summary of the design concept, performance aspects, and fabrication methods of the micro electromechanical system (MEMS) inertial switch is provided. Different MEMS inertial switch studies were reviewed that emphasized acceleration directional and threshold sensitivity, contact characteristics, and their superiorities and disadvantages. Furthermore, the specific fabrication methods offer an applicability reference for the preparation process for the designed inertial switch, including non-silicon surface micromachining technology, standard silicon micromachining technology, and the special fabrication method for the liquid inertial switch. At the end, the main conclusions of the current challenges and prospects about MEMS inertial switches are drawn to assist with the development of research in the field of future engineering applications.
