Because the MMC is a converter topology, the most common approach for controller design is considering the conventional converter model to design the controller accordingly. Though this approach ignores the internal dynamics of the MMC, the modular structure enables distribution of the capacitors in six arms of the MMC. However, this distribution leads to a complex internal dynamic that affects the controller operation and cannot be disregarded. In this study, a detailed fundamental and circulating current model of the MMC is developed while considering its internal dynamics. The detailed modelling reveals cross-and inter-couplings. On the basis of the detailed model and analysis of the couplings, three controllers have been proposed. Moreover, the performances of the proposed and conventional controllers have been analysed and compared under steady-state and active and reactive power changes. The proposed controllers are observed to achieve improved decoupling compared to that achieved by the conventional controller.

Two classes, TU radical ST lightlike submanifolds and TU ST anti-invariant lightlike submanifolds, are studied. The necessary and sufficient conditions for the distributions to be integrable and the induced connection to be a Levi-Civita or metric connection on these mentioned lightlike submanifolds are derived. Further, some important results are established on the geometry of these submanifolds. This paper contributes various important results that help the further study of the geometry of metallic semi-Riemannian manifolds.

In this study, emissions of CO, CO 2 , and 76 volatile organic compounds (VOCs) and fine particulate matter (PM 2.5) were quantified to better understand the relationship between cook fire emissions and ambient ozone and secondary organic aerosol (SOA) formation. Cooking was carried out by a local cook, and traditional dishes were prepared on locally built chulha or angithi cookstoves using brushwood or dung fuels. Cook fire emissions were collected throughout the cooking event in a Kynar bag (VOCs) and on polytetrafluoroethylene (PTFE) filters (PM 2.5). Gas samples were transferred from a Kynar bag to previously evacuated stainless-steel canisters and analyzed using gas chromatography coupled to flame ionization, electron capture, and mass spectrometry detectors. VOC emission factors were calculated from the measured mixing ratios using the carbon-balance method, which assumes that all carbon in the fuel is converted to CO 2 , CO, VOCs, and PM 2.5 when the fuel is burned. Filter samples were weighed to calculate PM 2.5 emission factors. Dung fuels and angithi cookstoves resulted in significantly higher emissions of most VOCs (p < 0.05). Utilizing dung-angithi cook fires resulted in twice as much of the measured VOCs compared to dungchulha and 4 times as much as brushwood-chulha, with 84.0, 43.2, and 17.2 g measured VOC kg −1 fuel carbon, respectively. This matches expectations, as the use of dung fuels and angithi cookstoves results in lower modified combustion efficiencies compared to brushwood fuels and chulha cookstoves. Alkynes and benzene were exceptions and had significantly higher emissions when cooking using a chulha as opposed to an angithi with dung fuel (for example, benzene emission factors were 3.18 g kg −1 fuel carbon for dungchulha and 2.38 g kg −1 fuel carbon for dung-angithi). This study estimated that 3 times as much SOA and ozone in the maximum incremental reactivity (MIR) regime may be produced from dung-chulha as opposed to brushwood-chulha cook fires. Aromatic compounds dominated as SOA precursors from all types of cook fires, but benzene was responsible for the majority of SOA formation potential from all chulha cook fire VOCs, while substituted aromatics were more important for dung-angithi. Future studies should investigate benzene exposures from different stove and fuel combinations and model SOA formation from cook fire VOCs to verify public health and air quality impacts from cook fires.

This type of dependency on solar energy is seen due to its perpetual source of energy and negligible side effect. But the efficiency of solar cell is affected due to many internal factors (due to component used in manufacturing) as well as external/environmental factors (wind, dust, humidity, location etc.). The objective of this project is to analyse the effect of dust on the performance of PV system in Manipal University, Jaipur with the use of LABVIEW based data logger. All the important parameters (open circuit voltage, short circuit current, output power etc.) related to both the panels were noted down and compared with the use of characteristic curve. It was observed that reduction in power generation of unclean panel was 9% after 55 days.

This study explores the molecular composition of organic particles from household cooking emissions, with a focus on identifying fuel-specific compounds and BrC chromophores. Traditional meals were prepared by a local cook with dung and brushwood-fueled cookstoves in a village of Palwal district, Haryana, India. The cooking events were carried out in a village kitchen while controlling for variables including stove type, fuel moisture content, and meal. The particulate matter (PM<sub>2.5</sub>) emissions were collected on filters, and then analyzed via nanospray desorption electrospray ionization/high resolution mass spectrometry (nano-DESI-HRMS) and high performance liquid chromatography/photodiode array/high resolution mass spectrometry (HP...
