The wide adoption of the emerging SmartNIC technology creates new opportunities to offload application-level computation into networking layer, which frees burden host CPUs, leading performance improvement. Shuffle, all-to-all data exchange process, is a critical building block for network communication in distributed data-intensive applications and can potentially benefit from SmartNICs. In th...

Yanma odasından dışarıya transfer edilen ısı miktarı yanma verimini direkt etkilemektedir. Isı miktarının artması azaltmaktadır. Motorlarda termal kaplama yöntemleri ile azaltılarak verimi artmaktadır. Fakat odasının tamamının malzeme kaplanması buji ateşlemeli motorlarda vuruntu temayülünün artmasına ve emisyon değerlerinin kötüleşmesine neden olmaktadır. Vuruntu azaltılmasında en etkiyi yönte...

The combustion characteristics of an opposed-piston two-stroke gasoline engine are investigated with experiment. energy conversion and exergy destruction analyzed the organization method process is summarized. effects phase difference, scavenging pressure, injection timing, ignition dual spark plug scheme on performance discussed, respectively. heat release rate consistent conventional engine. ...

In recent years, the gasoline-fuelled internal combustion (IC) engine has been the subject of a constant drive towards improved fuel economy and increasingly stringent legislation concerning emissions. Both of these factors depend significantly on the quality of combustion that can be obtained, under a multitude of different engine running conditions. Misfire can cause serious damage to a catal...

The article discusses the most important facts from history of development miniature aircraft engines and carries out their comparative analysis. Already in 1930s, structural system characteristic model was established, which has hardly changed to this day. following sections compare various types engines: two-stroke four-stroke engines, spark-ignition glow plug with a push-pull cylinder arrang...

This paper focuses on effect of rhodium addition degradation behavior Ir-10 mass％Rh alloy for a spark plug during oxidation at elevated temperatures. Oxidation tests were conducted the temperature range from 1173 K to 1473 in Ar-21％O2 gas mixture clarify alloy. As result, there are three effects prevent degradation: (1) dissolution into iridium oxide scale below 1273 K, which decreases activity...

We present an open-source low-budget hardware and software prototype of a smart plug, and the principles behind its capability to align power demand with a reference signal, e.g. from local renewable energy generation. We envision its use on a platform that combines social-media with energy networks, where users provide bottom-up demand response voluntarily. This article has two main objectives...
