Unicast routing protocols for urban vehicular networks:review, taxonomy, and open research issues

Journal of Zhejiang University-Science C(Computers and Electronics) 2014年第7期15卷 489-513页

Over the past few years, numerous traffic safety applications have been developed using vehicular ad hoc networks(VANETs). These applications represent public interest and require network-wide dissemination techniques. On the other hand, certain non-safety applications do not require network-wide dissemination *** applications can be characterized by their individual interest between two vehicles that are geographically apart. In the existing literature, several proposals of unicast protocols exist that can be used for these non-safety applications. Among the proposals, unicast protocols for city scenarios are considered to be most *** implies that in city scenarios unicast protocols show minimal persistence towards highly dynamic vehicular characteristics, including mobility, road structure, and physical environment. Unlike other studies, this review is motivated by the diversity of vehicular characteristics and difficulty of unicast protocol adaption in city *** review starts with the categorization of unicast protocols for city scenarios according to their requirement for a predefined unicast path. Then, properties of typical city roads are discussed, which helps to explore limitations in efficient unicast communication. Through an exhaustive literature review, we propose a thematic taxonomy based on different aspects of unicast protocol operation. It is followed by a review of selected unicast protocols for city scenarios that reveal their fundamental characteristics. Several significant parameters from the taxonomy are used to qualitatively compare the reviewed protocols. Qualitative comparison also includes critical investigation of distinct approaches taken by researchers in experimental protocol evaluation. As an outcome of this review, we point out open research issues in unicast routing.

Corrosion resistance and thermal stability of sputtered Fe44Al34Ti7N15 and Al61Ti11N28 thin films for prospective application in oil and gas industry

引用

Progress in Natural Science:Materials International 2021年第5期31卷 688-697页

作者： Mahbub Alam Maruf syed Muhammad Mujtaba Rizvi Mohammed noor-A-Alam Donghyun Shin Waseem Haider Ishraq Shabib School of Engineering and Technology Central Michigan University Mechanical Engineering Indiana University-Purdue University Columbus

Fe-and Al-based thin-film metallic glass coatings(Fe44Al34Ti7N15and Al61Ti11N28) were fabricated using magnetron co-sputtering technique, and their corrosion performances compared against wrought 316 L stainless steel. The results of GI-XRD and XPS analyses demonstrated amorphous structure and oxide layer formation on the surface of the fabricated thin films, respectively. The potentiodynamic(PD) polarization test in chloridethiosulfate(NH4Cl + Na2S2O3) solution revealed lower corrosion current(Icorr)(0.42 ± 0.02 μA/cm~2 and0.086 ± 0.001 μA/cm~2 Vs. 0.76 ± 0.05 μA/cm~2), lower passivation current(Ipass)(1.45 ± 0.03 μA/cm~2 and1.83 ± 0.07 μA/cm~2 Vs. 1.98 ± 0.04 μA/cm~2), and approximately six-fold higher breakdown potential(Ebd) for Fe-and Al-based coatings than those of wrought 316 L stainless steel. Electrochemical Impedance Spectroscopy(EIS) of both films showed 4-and 2-fold higher charge transfer resistance(Rct), 7-and 2.5-times higher film resistance(Rf), lower film capacitance values(Qf)(10 ± 2.4 μS-sacm-2, and 5.41 ± 0.8 μS-sacm-2Vs. 18 ± 2.21 μSsacm-2), and lower double-layer capacitance values(Qdl)(31.33 ± 4.74 μS-sacm-2, and 15.3 ± 0.48 μS-sacm-2Vs.43 ± 4.23 μS-sacm-2), indicating higher corrosion resistance of the thin films. Cyclic Voltammetry(CV) scan exhibited that the passive films formed on the Fe-and Al-based coatings were more stable and less prone to pitting corrosion than the wrought 316 L stainless steel. The surface morphology of both films via SEM endorsed the CV scan results, showing better resistance to pitting corrosion. Furthermore, the thermal analysis via TGA and DSC revealed the excellent thermal stability of the thin films over a wide temperature range typically observed in oilgas industries.

Rice, a staple cereal crop in many parts of the world, has been confronted with multiple environmental stresses including high temperature, negatively impacts the booting as well as anthesis growth stages. The situation is further complicated by the changing climatic conditions, resulting in gradual escalation of temperature as well as changing the rainfall pattern and frequency, thus raising a concern of food security worldwide. The situation can be combat by developing rice varieties with excellent genetics with improved morpho-physiological, biochemical, and molecular mechanisms, together can minimize the adverse effects of heat stress. Here, several strategies(encompassing genetic and genomic, and mechanisms involved) for mitigating the impact of high temperature on rice have been discussed. Finally, the utilization of genomic knowledge in augmenting the conventional breeding approaches have been comprehensively elaborated to develop heat tolerant germplasm.
