We describe a novel cross-layer, resiliencefocused integrated modeling framework. This is targeted to help define ultra energy-efficient embedded systems in the post-14nm CMOS design era, without compromising system-level resilience. The targeted application domain is represented by the suite of applications and kernels announced as part of the ongoing PERFECT program sponsored by DARPA MTO.
The ambitious CO2 emission reduction targets for the transport sector set in Paris Climate Agreement require low-carbon energy solutions that can be commissioned rapidly. production of gasoline, kerosene, and diesel from renewable methanol using methanol-to-olefins (MTO) Mobil’s Olefins to Gasoline Distillate (MOGD) syntheses was investigated this study via process simulation economic analysis....

Using an organosilane surfactant as the mesopore director, hierarchical porous silicoaluminophosphate SAPO-34 is obtained as an assembly of nanocrystallites intergrown into cubic micrometer-sized crystals, which show excellent performance in MTO reactions with a remarkably prolonged catalyst lifetime and enhanced selectivity of ethylene and propylene compared to the conventional microporous SAP...
SSZ-13 materials have been synthesized with varying amounts of Al to produce samples with different concentrations of Brønsted acid sites, and consequently, these SSZ-13 materials contain increasing numbers of paired Al heteroatoms with increasing Al content. These materials were then characterized and tested as catalysts for the methanol-toolefins (MTO) reaction at 400 °C and 100% methanol con...
Over 20 years of scholarship suggests that living in America’s poorest and most dangerous communities diminishes the life course development of children and adults. In the 1990s, the dire conditions of some of these neighborhoods, especially those with large public housing developments, prompted significant policy responses. In addition to the demolition and redevelopment of some of the project...
At the Galician coast, mussels are cultured on vertical ropes attached to floating rafts, which are cleaned in situ with tars or waterproof paints. The present study analyses the com position and the toxic risk of several compounds used during maintenance, in order to improve mussel-farming practices. The toxic risk was determined in relation to that of benzo(a)pyrene (BaP) by calculating the c...
Silicoaluminophosphate SAPO-34 molecular sieve nanocrystals have been prepared by a post-synthesis milling and recrystallization method, which is further proven to be universally applicable to other SAPO molecular sieves. The obtained SAPO-34 with reduced Si enrichment on the external surface shows considerably improved catalytic performance in the MTO reaction.
غربال مولکولی نانوساختار SAPO-34 بهترین کاتالیست شناخته شده از جهت انتخاب پذیری برای فرایند تبدیل متانول به الفین های سبک ( MTO ) می باشد. در سنتز غربالهای مولکولی ماده الگوساز نقش های مهمی را ایفا میکند. در تحقیق حاضر، برای سنتز SAPO-34 از مخلوط الگوسازهای تری اتیل آمین و مورفولین استفاده شد. برای ارتباط دادن خواص کاتالیستهای سنتز شده با عملکرد آنها در فرایند از آنالیزهای XRD ، FESEM ، EDX...
Abstract Multiobjective multitasking optimization (MTO) is an emerging research topic in the field of evolutionary computation, which has attracted extensive attention, and many (EMT) algorithms have been proposed. One core issues, designing efficient transfer strategy, scarcely explored. Keeping this mind, paper first attempt to design strategy based on multidirectional prediction method. Spec...
