أثبتت الدراسات أن المخطط البياني للضغط العامل في أسطوانة المحرك البحري يمكن أن يعطي معلومات كثيرة ليس فقط عن الضغط بأنواعه، و إنما عن عدد كبير من المقادير المفيدة في تحسين أداء المحرك، و لهذا نحاول في هذا البحث دراسة المؤشرات التي تؤدي إلى إكمال الصورة الفيزيائية لدورة العمل. تتمثل هذه المحاولة في استخدام موديل رياضي شامل و عميق للحصول على تلك المؤشرات و استخدامها لتكوين صورة واضحة عن دورة العمل اعتماداً على ديناميكية الإصدار الحراري في الأسطوانة، سعياً لتحسين الأداء و تحقيق استثمار فني أفضل و أكثر اقتصاديةً نصل بالنتيجة إلى جملة من الاستنتاجات و التوصيات التي تساعد عند اعتمادها على الحصول على مواصفة أكمل لدورة العمل و بدقة عالية للعملية الحسابية.
Studies have proven that the indicatingpressure chart of marine engine cylinder can providemany information not only about pressure, but also about a large number of parameters that are useful in enhancing engine performance. Therefore, in this research paper, we attempt to study the indicators that complete the physical image of the work cycle. This attempt uses an elaborate and comprehensive mathematical model for obtaining and using these parameters in order to form a clear image of the work cycle based on the dynamics of heat release in the cylinder, for the purposes of enhancing performance and achieving a more efficient, more economical mechanical operation. As a result we will reach a number of conclusions and recommendations which,upon being approved and used, can help to achieve with great mathematical accuracy a more optimized characteristic of the work cycle.

In this study, we have developed a mathematical model, which formed the basis for
the development of a digital diagnostic model, for the question of the relation between the
engine torque (and therefore power), and the clearances in the basic and s
econdary
bearings of the crankshaft, to diagnose clearance values in these bearings, /which will
inevitably affect on the torque and the vibrations of the engine/, where multiple and
various grand-scale case experiments were carried out through simulation and arithmetic
experimentation on a diagnostic model, which constituted the first and main phase (the
instruction phase) of the full diagnosis. And at the end we discussed the results and put
some conclusions and recommendations to complete the work in the future.
This study aims to make the function of the propulsion system on ship flexible at
various working conditions on sea, and it concentrates on the abnormal conditions that
form a hard challenge for the ship.
We dealt in this paper some abnormal worki
ng cases; include sailing in shallow
waters, storm condition and fouling on ship hull.
At these three cases there is a rise in stress on engine parts, higher fuel consumption,
decrease in the speed of the ship and other problems.
To solve these problems we developed a program on C# language, that simulate the
elements of propulsion system on ship and coordinates between the engine and the
propeller through varying some parameters to ensure sailing of ship at suitable speed, at
optimal fuel consumption for the engine, and to keep the propulsion elements at good state.
Multilingual language models achieve impressive zero-shot accuracies in many languages in complex tasks such as Natural Language Inference (NLI). Examples in NLI (and equivalent complex tasks) often pertain to various types of sub-tasks, requiring di
fferent kinds of reasoning. Certain types of reasoning have proven to be more difficult to learn in a monolingual context, and in the crosslingual context, similar observations may shed light on zero-shot transfer efficiency and few-shot sample selection. Hence, to investigate the effects of types of reasoning on transfer performance, we propose a category-annotated multilingual NLI dataset and discuss the challenges to scale monolingual annotations to multiple languages. We statistically observe interesting effects that the confluence of reasoning types and language similarities have on transfer performance.

Multi hop wireless networks face many challenges basically the
limitation of bandwidth, loss of packets because of many problems
in wireless medium also loss of paths because of the random and
unpredictable movement of wireless nodes, which reduce
the
performance of these networks. Recently, Network coding has been
used as promising technology that achieves the reliable transfer of
data in wireless networks with high throughput. Considering the
efficiency of this technology and with benefiting from both the
same cost paths and the broadcasting property of wireless medium,
a multi transmission mechanism for random linear network coding
has been proposed in multi hop wireless networks, which depends
on multicasting of coded packets on the same cost paths.
