Space meteorology, primarily the ionosphere, is the largest cause of GNSS (Global Navigation Satellite System) systematic errors. In this paper, the influence of the ionosphere on satellite ranging is reviewed, and the causes of the error are discussed from the perspective of the receiver. In addition, we will discuss the ionospheric delay changes based on the ionospheric delay data under normal conditions in the past and the maximum (delay) change data on some solar storm days.

Scintillation, a highly random anomaly in the ionosphere, will also be included in our discussion, and relevant demonstrative data on the effects of this phenomenon will be provided. Subsequently, we analyze the impact of these two ionospheric phenomena on the differential GNSS systems commonly used by flight monitoring agencies around the world, and also give a picture of the performance of the FAA's WAAS system under normal and abnormal ionospheric conditions. Finally, we will discuss the 11-year cycle phenomenon of the ionospheric and its implications for GNSS.

During periods of relative calm in solar activity, GNSS has been widely used in the aviation industry. However, we are now emerging from this lull, and the most active period of solar activity is expected to be in 2013, when ionospheric influences are likely to intensify. Flight detection activities may also be affected.

Therefore, it is important for flight monitoring agencies to take a long-term view and closely monitor the activities of the ionosphere to ensure the integrity of their data.

Space weather, primarily in the ionosphere, produces the greatest GNSS errors. This article reviews the effects of the ionosphere.

Satellite ranging measurements and how the effect accounts for receiver discussions. In addition, the variant.

Ionospheric delay will be discussed along with historical ionospheric delay data in general as well as for certain products.

Changes with solar storms on the highest days. Scintillation, a highly random anomaly in the ionosphere, will also.

The data discussed and presented demonstrate the effect of this phenomenon. The effects of these two ionospheres will be.

Differential GNSS systems, their role, a common system, and the terminology used by many flight inspection agencies were examined.

Globe. The FAA's WAAS ionosphere will also behave in both normal and abnormal ways.

Host. Finally, the 11-year cycle will be discussed with the ionosphere with the impact of GNSS. Widely used.

GNSS has largely taken place during aviation during the time when solar activity was relatively calm, however, we are now getting rid of.

That quiet period and the time of maximum solar activity is expected to occur around 2013 with a possible increase in the ionosphere.

Effect. Unannounced inspection activities may be affected, so it will be prudent flight monitors to monitor the ionosphere.

activities to ensure the integrity of their data.

But the author does not try to organize and synthesize it, and the historical annotation is extremely simple. Similar covers some special regions or types of names, such as Lewis annotated with gazetteer directories on Washington and Oregon, and a study of toponyms in High Sierra, California. [5]

However, some attempts have been made to analyze and interpret the various stages of systematic nomenclature. Even when the main part of a study has taken the form of lists and notes on individual place names, the author generally provides a broad explanatory introduction. Whenever this has been done, we have the rudiments of "ecological" research.

Among recent American examples, we can mention Von Engeln and Urquhart's "background keys to geographical names",[6] Espenshade's "Pennsylvania toponym",[7] and Fitzpatrick's "Nebraska toponym". [8] Recently, a brief discussion conducted by "A Study of American Geographical Names: An Incomplete Review" has been published.

9] Ecology of toponymic coverage.

We have always used the term "ecological" in this regard, because there is a similarity between the vegetation cover and the place name that we might have conceived to encompass the landscape – not perfect, but obvious enough in any form. Just as the formation of many plants involves a gradual change in the elements between those that are transplanting and those that are dying, we can give any given area a set of names that will be adopted, others that are perfectly acceptable, and some that are disappearing. There are also some place names that may be called death, i.e., those that have been completely discarded in local use, but can only be found in old maps or other accounts.

The extant names of any given region, at any given time, are the accumulation of the past, the quality and density of which depend partly on the density of the population, partly on the length of time the country has been occupied, and partly on the characteristics of the various waves of migration that swept through the region, and partly on the nature of the ground.

To investigate the interaction between the sensor QB and Zn2 CD2, a hydronuclear magnetic resonance titration was also performed (supporting InfoFigure 5 and Table S2). When interacting with Zn2 and CD2, the proton of methoxy CH3 undergoes a significant upfield shift (ΔΔZN= ΔΔCD=), indicating that the oxygen atom of the methoxy group binds strongly to Zn2 CD2. The protons in the adjacent position in the low field of pyridine are shifted from and due to the n-metal consonance effect, respectively.

At the same time, a similar high-field shift was observed in the proton case at position 3 of quinoline, revealing a direct interaction between the quinoline platform and metal ions. When further introducing 4 equivalents of CD2 into the ZNQB solution, comparing Figure 1D with Figure 5B, the chemical shifts of all protons are significantly altered and almost identical to those of CDQB alone (Figure 5C). This finding suggests that QB has a higher affinity for CD2 than for Zn2, which incurs the ion displacement process.

Overall, we have developed a new fluorescence sensor, QB. It shows a ratiometric response to Zn2+ and a Chef response to CD2 based on the Chef and ICT mechanisms. Moreover, we demonstrate that the central ion of ZNQB can be displaced by CD2 to obtain another ratiometric sensing signal output.

Therefore, QB can be a dual-mode CD2 selective sensor through the Chef mechanism and the ratio displacement approach.

To investigate the interaction between the sensor QB and Zinc Cd+, a 1 h NMR titration was also performed (Figure 5 and Table II, supporting information). Through interaction with zinc+ and CD2+, significant high-field changes (δδzn) are experienced for methoxy CH3 and protons; δcd) parts per million, indicating a strong zinc-cadmium bonded methoxy oxygen atom +. The proton in the ortho-site of pyridine has a low field from to transfer (zinc and cadmium), respectively, by the effect of N-metal mating.

At the same time, a similar high-field change is also seen at the 3-quinoline position of protons, suggesting a direct interaction between the platform and metal ions between quinolines. When the further integration of Cadmium equivalent 4+ into the ZNQB solution was introduced, comparing 5B to Figure 5, all proton chemical shifts changed significantly, and almost only of these were the same (Figure 5C). This finding suggests that blood flow has a higher affinity for cadmium than zinc, thus incurring the process of ion migration.

In summary, we have developed a new type of fluorescence sensor, the QB terminal. It shows a ratio of responses to Zn2+ on the basis of two cooks, but a cook responds to the ICT mechanism of CD2+. In addition, our analysis shows that the ZNQB of ** ions can be replaced with CD2+, resulting in another ratio of the output of the induced signal.

Therefore, QB can be a dual-mode CD2+ method of chef mechanism and ratio displacement through selective sensors.

This book is aimed at bright students who have only scratched the surface of science. For the layman in the field of science, science may be just a stale hut made of redundant data; Otherwise, it is the product of piles of mechanical parts; And scientists are even seen as some kind of magician. This book can be used as a reference book for all natural science courses, and provides relevant advice and help for those who are trying to understand the world today. It can be independent of any one course – just to make science more accessible and understandable.

We hope that this book will lead readers to a broader perspective on what science is, what scientists are, and what they do. As a result, readers will gain a deep appreciation of the relevance of science to our culture and the various roles that science plays in our cultural life. In addition, readers will appreciate the close connection between the field of science and some of the values and philosophies that prevail in our culture.

I translated that article, and I forgot to log it in just now.

Hehe, plus points added here.

A lot of traffic information about Chicago has been re-evaluated to determine what drivers driving in this area think about transportation. These descriptions are some of the information displayed on the traffic electronic communication signs on the highway buildings. After assessing the condition of seven congested sections, six of them were found to be moderately congested.

This information contains descriptive information, traffic volume information, but no information about traffic congestion.

In the case of congestion, information about traffic accidents and information that causes severe congestion are the biggest causes of congestion. Congestion due to speed is the second most important reason. For other congestion situations, congestion due to speed is at the top of the list.

The proportion of the remaining two causes (excluding traffic accidents) is also quite high, but both are far lower than the speed causes. Variables about traffic delays and transit times were of little value relative to other variables and were not expected at all by respondents.

Are you looking for the answer or the examiner, as long as you understand the question, you can't figure it out, and if you don't use tools, I don't understand.

In the past, secretaries were all men, and at that time, even a little exposure of stockings was considered too shocking and would interfere with the serious work in the office.
