Abstract:
The development of automotive technology is very fast, we can find this in today's vehicles that use a lot of very sophisticated technology, namely in terms of engines, electricity, and its newest features, especially on two-wheeled vehicles. Therefore, the user community is required to be more selective in choosing a vehicle both in terms of quality and quantity. Including in the selection of spare parts on vehicle engines must use good quality, this is useful as a motorbike power booster, especially in the ignition system, namely spark plugs as a vital tool that sprinkles sparks in the combu

Abstract:
During the manual grinding of blades, the workers can estimate the material removal rate based on their experiences from observing the characteristics of the grinding sparks, leading to low grinding accuracy and low efficiency and affecting the processing quality of the blades. As an alternative to the recognition of spark images by the human eye, we used the deep learning algorithm YOLO5 to perform target detection on spark images and obtain spark image regions. First the spark images generated during one turbine blade-grinding process were collected, and some of the images were selected as t

Abstract:
Abstract We report on our investigation of the evolution of a system of spark discharges in the inner acceleration region (IAR) above the pulsar polar cap. The surface of the polar cap is heated to temperatures of around 106 K and forms a partially screened gap (PSG), due to thermionic emission of positively charged ions from the stellar surface. The spark lags behind corotation speed during their lifetimes due to variable E × B drift. In a PSG, spark discharges arise in locations where the surface temperatures go below the critical level (T i ) for ions to freely flow from the surface. The sp

Abstract:
The development of the automotive world experienced rapid development, and the most prominent development was in the ignition system. In this study will be discussed about the gasoline motor ignition system, especially the effect of spark plug gap on the power produced by the gasoline engine. The aim of research is to produce a good combustion process in the engine combustion chamber by determining the distance of the spark plug so that the sparks produced are perfect. The right spark plug gap will produce perfect combustion and the power produced will also be in accordance with the specificat

Discrete Ca2+ release events (Ca2+ “sparks”) were recorded in cut segments of single frog skeletal muscle fibers using a video-rate laser-scanning confocal microscope operating in line-scan mode (63 μs per line). Fibers loaded with the Ca2+ indicator fluo-3 were voltage clamped at a holding potential of 0 mV, briefly reprimed at −90 mV, and then strongly depolarized with a large test pulse to activate any reprimed voltage sensors. Using this high time resolution system, it was possible to record individual Ca2+ sparks at ∼30-fold higher time resolution than previously attained. The resulting n

Ca2+ sparks are highly localized cytosolic Ca2+ transients caused by a release of Ca2+ from the sarcoplasmic reticulum via ryanodine receptors (RyRs); they are the elementary events underlying global changes in Ca2+ in skeletal and cardiac muscle. In smooth muscle and some neurons, Ca2+ sparks activate large conductance Ca2+-activated K+ channels (BK channels) in the spark microdomain, causing spontaneous transient outward currents (STOCs) that regulate membrane potential and, hence, voltage-gated channels.

The spark energy was varied by changing the spark plug gap and the coil-on-time.

It also allows detecting abnormal behaviors on the IT system, for example, multiple suspicious actions performed by the same account. The correlation of security events increases the security of the system and reduces the number of false positives. The correlation of the events is made thanks to pre- existing cor

Abstract:
Using a laser, as opposed to a conventional (electrical) spark plug, to create combustion initiating spark is potentially advantageous for several reasons: flexibility in choosing and optimizing the spark location, in particular, to move the spark away from solid heat sinks; production of a more robust spark containing more energy; and obviation of electrode erosion problems. These advantages may lead to an extension of the lean limit, an increase in engine thermal efficiency, and the concomitant benefits of reduced pollutant emissions.

Abstract:
Prior PRCI funded projects identified the ability of a continuous engine performance monitor (CEPM) to fulfill the likelihood of industry acceptance as a Performance Monitoring alternative to a Continuous Emission Monitoring System CEMS in future monitoring requirements for typical pipeline engines. This current project investigated an integrated and expert level monitoring system on a pipeline engine equipped with a CEPM system and assessed the ability of this expert system to detect ignition and combustion related problems. The system demonstrated the ability to detect combustion faults down

Abstract:
High exhaust emissions reduction efficiencies from a spark ignited (SI) internal combustion engine utilizing an NSCR catalyst system requires complex fuel control strategies. The allowable equivalence ratio operating range is very narrow where NSCR systems achieve high exhaust emissions reduction efficiencies of multiple species. Current fuel control technologies utilizing lambda sensor feedback are reported to be unable to sustain these demands for extended operation periods and when transients are introduced. Lambda sensor accuracy is the critical issue with current fuel controllers. The goa

Abstract:
The increasingly strict air emission regulations may require implementing Non-Selective Catalytic Reduction (NSCR) systems as a promising emission control technology for stationary rich burn spark ignition engines. Many recent experimental investigations that used NSCR systems for stationary natural gas fueled engines showed that NSCR systems were unable to consistently control the exhaust emissions level below the compliance limits. Modeling of NSCR components to better understand, and then exploit, the underlying physical processes that occur in the lambda sensor and the catalyst media is no

Abstract:
In early 2022, the Agricultural Policy Research in Africa (APRA) Programme of the Future Agricultures Consortium (FAC), in partnership with the United Nations Sustainable Development Solutions Network and Foresight4Food, held an e-Dialogue series: Towards an Equitable and Sustainable Transformation of Food Systems. This followed an earlier, highly successful series organised with the same partners in the second half of 2020 on What Future for Small-Scale Farming? The latest series included three online Zoom sessions led by APRA over January-March 2022 on topics including COVID-19 and its effec
