Research on Fatigue Invalidation of A Submarine Pipeline Span Subjected to Waves and Currents

Considering both the axial force on the spanning pipeline and influence of sea waves and currents, a perpendicular nonlinear vibration equation which satisfies given boundary conditions is .set up according to the factual soil supports for the pipeline. Based on the inherent modes of vibration determined from the equation of motion describing free vibrations, the differential equations for the time domain of the equation solution are deduced and established. By the application of time and frequency domain analysis, the sea wave and current force spectrum is derived from wave spectrum and is used as the input spectrum of the vibration equation to deduce the output spectrum, and further determine the probability distribution of displacement and strain. On this basis, the fatigue invalidation probability of the spanning pipeline is found out according to the theory of reliability. Finally, by means of calculation and analysis of a practical sample, the degree of effect of some important parameters on fatigue invalidation of the spanning pipeline span is determined.

Research on Constructing Contoursfrom Regular Terrain GridsContaining Invalid Data

A new method for constructing contours from complicated terrain elevation grids containing invalid data is put forward. By using this method, the topological consistency of contours in groups can be maintained effectively and the contours can be drawn smoothly based on boundaries pre-searching and local correction. An experimental example is given to demonstrate that the contours constructed by this method are of good quality.

A Novel Cache Invalidation Scheme for Mobile Networks

In this paper, we propose a strategy of maintaining cache consistency in wireless mobile environments, which adds a validation server （VS） into the GPRS network, utilizes the location information of mobile terminal in SGSN located at GPRS backbone, just sends invalidation information to mobile terminal which is online in accordance with the cached data, and reduces the information amount in asynchronous transmission. This strategy enables mobile terminal to access cached data with very little computing amount, little delay and arbitrary disconnection intervals, and excels the synchronous IR and asynchronous slate （AS） in the total performances.

Invalidation manner and mechanism of new type NbO electrolytic capacitor anode

Niobium suboxide powder was pressed and sintered in vacuum into NbO electrolytic capacitor sintered anode..High voltage and constant current formation experiment was performed on NbO electrolytic capacitor anode,during which electrolyte was 0.01 % Ha PO4 solution, temperature was 90 C and current was 50 mA per gram sample. Through the relationship between anode voltage and time and scanning electron microscopy(SEM) images of invalidated anode and normal forming anode, invalidation manner and mechanism of NbO electrolytic capacitor anode were discussed. The results show that, the main invalidation manner of NbO electrolytic capacitor anode is not short circuit but open circuit, which is different to that of traditional Ta electrolytic capacitor anode. The reason of invalidation is that anode oxide film whose thickness increases gradually penetrates the "connection neck" among anode powder particles, which leads to the open circuit invalidation of anode. Compared with Ta electrolytic capacitor,NbO electrolytic capacitor has better security.

INFLUENCE OF BLADES' STRESS STATE ON FRANCIS TURBINE RUNNER'S INVALIDATION

Numerical simulation on Francis turbine runner＇s welding temperature field and welding stress field is carded out on the base of solving the problem of welding heat source＇s movement along any spatial routes and the problem of heat elimination between the complicated blade and air. The evolvement law of welding stress and the distribution of the stress field after welding are obtained. The results indicate that the peak value of the welding residual stress appears on the outlet edge of blade near the contact area between blade and band or blade and crown. Associated with the distribution of the runner＇s working stress, the invalidation reason of the Francis turbine runner is explained.

Impact of Mandatory Provisions on the Validity of Juristic Acts: A Path for Legal Policy Analysis

Contrary to the approach in judicial practice,Paragraph 1,Article 153,of the Civil Code of the People’s Republic of China,as a rule of invalidity for violating mandatory provisions,does not adopt a dichotomy towards mandatory provisions with effectiveness and administrative characteristics,yet it maintains the legislative philosophy of differentiation.It leaves unspecified whether mandatory provisions that do not explicitly render a juristic act invalid impact the act’s validity,entrusting this determination to the discretion of judges on a case-by-case basis.When judges,under the authority of Paragraph 1,Article 153 of the Civil Code,explore the normative intent of mandatory provisions to assess their effect on the validity of juristic acts,they should engage in legal policy analysis centered on consequence-based argumentation to overcome the limitations of norm typological analysis.This analysis employs a reasoning model predicated on the normative purpose,utilizing a consequencefocused interpretative approach for formulating and arguing propositions of rules applicable to pending cases,thereby arriving at case-specific conclusions.Since the invalidation of juristic acts serves as an auxiliary regulatory tool for the state economy and society,a consequence-oriented interpretation needs to be based on the idea of mutual instrumentalization of public and private laws.This entails predicting the outcomes of negating the validity of a juristic act in industrial regulatory scenarios and assessing these outcomes within the framework of public and private regulatory instruments.

Adsorption Mechanism of Polycarboxylate-Based Superplasticizer in CFBC Ash-Portland Cement Paste

Circulating fluidized bed combustion （CFBC） ash exhibits the desirable pozzolanic activity which makes it a potential supplementary cementitious material to replace cement for concrete production. However, the high unburnt carbon content and porous surface structure of CFBC ash may adsorb water reducer and thereby significantly reduce the efficiency of water-reducing agents. The adsorption mechanism of polycarboxylate superplasticizer in CFBC ash-Portland cement paste was investigated by ultraviolet-visible spectrophotometer, and the conception of ＂invalid adsorption site＂ of CFBC ash was presented. The results show that the adsorption behavior of polycarboxylate superplasticizer in coal ash-Portland cement paste can be described by Langmuir isothermal adsorption equation. The adsorption capacity of CFBC ash-Portland cement paste is higher than that of pulverized coal combustion （PCC） fly ash-Portland cement paste. Moreover, the adsorption amount of polycarboxylate superplasticizer increases with the ratio of ash-to-cement in the paste. At last, the fluidity of CFBC ash-Portland cement paste is lower than that of the PCC fly ash paste. This work suggests that when CFBC ash is used as concrete admixture, the poor flowability of the cementitious system due to the high adsorption of water and water-reducing agent should be taken into consideration.

Improved Square-Root UKF Algorithm for State Estimation of Nonlinear Systems

The square-root unscented Kalman filter （SR- UKF） for state estimation probably encounters the problem that Cholesky factor update of the covariance matrices can＇t be implemented when the zero＇th weight of sigma points is negative or the mnnerical computation error becomes large during the faltering procedure. Consequently the filter becomes invalid. An improved SR-UKF algorithm （ISR- UKF） is presented for state estimation of arbitrary nonlinear systems with linear measurements. It adopts a modified form of predicted covariance matrices, and modifies the Cholesky factor calculation of the updated covariance matrix originating from the square-root covariance filtering method. Discussions have been given on how to avoid the filter invalidation and further error accumulation. The comparison between the ISR-UKF and the SR-UKF by simulation also shows both have the same accuracy for state estimation. Finally the performance of the improved filter is evaluated under the impact of model mismatch. The error behavior shows that the ISR-UKF can overcome the impact of model mismatch to a certain extent and has excellent trace capability.

Analysis of Factors Influencing the Effect of Red Blood Cell Suspension Infusion in Children

Objective: The related factors of no improvement of hypoxia and ineffective infusion were analyzed to provide new ideas, clinical observation and evaluation pathway for RBC transfusion in clinical children. Methods: Retrospective analysis from January 2020 to December 2020, Guangzhou women and children’s medical center hospital in the emergency observation room of 249 children under 1 month to 18 years of blood cell suspension infusion, analyze the clinical effect of red blood cell infusion and children gender, age, fever after transfusion, disease type, delay transfusion. The possible influencing factors were analyzed by logistic regression. Results: Invalid transfusion was associated with the type of transfusion product (P = 0.032), logistic regression analysis showed that patients infused with washed RBC suspension were 3.231 times more likely to not achieve the expected effect than those infused with RBC suspension (P = 0.025). Failure transfusion was associated with the type of transfusion products. In ineffective transfusion was closely related to post-transfusion fever (P P P = 0.031). Logistic regression analysis showed that fever after transfusion was a risk factor for no improvement of hypoxia (OR = 5.809, P = 0.001), and the improvement of hypoxia in adolescent children was 10.744 times higher than that of infants (0 - 3 years old). Late transfusion hypoxia improvement was 4.212 times more likely to achieve no effect than timely transfusion. If ineffective infusion of red blood cells is considered and hypoxia after transfusion is not improved, univariate suggests a close correlation with fever after transfusion (P = 0.002), logistic regression analysis showed that fever after transfusion was an independent risk factor (OR = 7.258, P = 0.002). Conclusion: There was no correlation between the ineffective transfusion of red blood cells and the type of disease affected in the child. Infusion of red cell suspension has an advantage over the wash red cell infusion. Ineffective RBC transfusion and no improvement in hypoxia after transfusion were closely related to post-transfusion fever, with no difference between children in all age groups. Red blood cell infusion in pediatric clinical treatment activities should pay attention to adolescent children, especially female children to give more attention, and give timely red blood cell infusion as much as possible.

Apropos 1+2+3+4+5+...=<img src="http://latex.codecogs.com/gif.latex?-\frac{1}{12}"title="-\frac{1}{12}"/>: Mapping Infinity in Light of the Number Circle (or Cycle), in L. Euler’s Footsteps and with the Aid of Two Dimensional Infinite Series, and Replacing Negative Infinity and Positive Infinity with Just Infinity

The number circle—that is, the notion that the largest possible positive numbers are followed by infinity and then by the smallest possible negative numbers—is not new. L. Euler defended it in the eighteenth century and, before him, J. Wallis considered something vaguely similar. However, in the nineteenth century, the number circle was for the most part abandoned—even if something similar is on occasion accepted in geometry, in the sense that space is circular. The design of the present paper is to present positive proof of the veracity of the number circle and therefore, at the same time, to falsify the number line. Verifying the number circle implies falsifying negative infinity and positive infinity—infinity instead being neither negative nor positive, just like 0. Part of said proof involves showing that infinity can be defined both as 1+1+1+1+1+1+... and as -1-1-1-1-1-... and that the following Equation applies: 1+1+1+1+1+1+...=-1-1-1-1-1-... The principal mathematical technique that will be used to provide said proof is introduced here for the first time. It is called the two dimensional infinite series. It is an infinite series of infinite series. Some additional observations regarding the geography of infinity will be made. A more detailed description of the geography of infinity will be reserved for other papers. The Equation is discussed in this paper only to the extent that the attention that has been paid to it has necessitated the construction of a theory of infinity that, upon closer inspection, makes the Equation more self-evident and intuitively apparent;a fuller discussion will take place in a later paper.

Intelligent Predetermination of Generator Tripping Scheme: Knowledge Fusion-based Deep Reinforcement Learning Framework

Generator tripping scheme(GTS)is the most commonly used scheme to prevent power systems from losing safety and stability.Usually,GTS is composed of offline predetermination and real-time scenario match.However,it is extremely time-consuming and labor-intensive for manual predetermination for a large-scale modern power system.To improve efficiency of predetermination,this paper proposes a framework of knowledge fusion-based deep reinforcement learning(KF-DRL)for intelligent predetermination of GTS.First,the Markov Decision Process(MDP)for GTS problem is formulated based on transient instability events.Then,linear action space is developed to reduce dimensionality of action space for multiple controllable generators.Especially,KF-DRL leverages domain knowledge about GTS to mask invalid actions during the decision-making process.This can enhance the efficiency and learning process.Moreover,the graph convolutional network(GCN)is introduced to the policy network for enhanced learning ability.Numerical simulation results obtained on New England power system demonstrate superiority of the proposed KF-DRL framework for GTS over the purely data-driven DRL method.

Performance evaluation method of hybrid navigation constellations with invalid satellites

The construction of a navigation system plays an important role in the development of national politics,economy and military affairs.Nowadays,the Beidou navigation system is facing a transition period from the regional navigation system to the global one.For the global constellation,the system performance will not be seriously degraded when one or two satellites are invalid,but it is out of case for the regional constellation,which usually has fewer satellites and less redundancy.This paper deals with this problem of hybrid constellations and analyzes the influence of the disabled satellites on the system.With hybrid constellations and simulation methods designed,the influence of invalid satellites on the navigation system is fully investigated.

Complex spatial patterns delay the discovery and location of food by rodents

Spatial patterns in heterogeneity are generally deemed a central causal factor influencing the physiology and behavior of animals in ecological systems.However,knowledge remains limited about how such patterns influence food discovery by animals.We inferred that spatial heterogeneity plays a key role in animal food discovery and location.To prove this inference,we tested food locating parameters by 2 rodent species,Apodemus agrarius and Lasiopodomys brandtii,in different heterogeneous environments.Our results showed that spatial heterogeneity significantly influenced the food locating time of rodents,with food locating time increasing with increasing spatial heterogeneity.Furthermore,spatial heterogeneity significantly influenced invalid excavations(digging in the wrong place).Finally,spatial heterogeneity significantly influenced the frequency that heterogeneous objects were explored.Supporting our inference,our results indicate that spatial heterogeneity significantly influences the foraging behavior of animals.Consequently,increased spatial heterogeneity will impair the food locating success of rodents.We believe that this work will broaden our understanding of plant–animal interactions.

Notes for genera:basal clades of Fungi(including Aphelidiomycota,Basidiobolomycota,Blastocladiomycota,Calcarisporiellomycota,Caulochytriomycota,Chytridiomycota,Entomophthoromycota,Glomeromycota,Kickxellomycota,Monoblepharomycota,Mortierellomycota,Mucoromycota,Neocallimastigomycota,Olpidiomycota,Rozellomycota and Zoopagomycota)

Compared to the higher fungi(Dikarya),taxonomic and evolutionary studies on the basal clades of fungi are fewer in number.Thus,the generic boundaries and higher ranks in the basal clades of fungi are poorly known.Recent DNA based taxonomic studies have provided reliable and accurate information.It is therefore necessary to compile all available information since basal clades genera lack updated checklists or outlines.Recently,Tedersoo et al.(MycoKeys 13:1–20,2016)accepted Aphelidiomycota and Rozellomycota in Fungal clade.Thus,we regard both these phyla as members in Kingdom Fungi.We accept 16 phyla in basal clades viz.Aphelidiomycota,Basidiobolomycota,Blastocladiomycota,Calcarisporiellomycota,Caulochytriomycota,Chytridiomycota,Entomophthoromycota,Glomeromycota,Kickxellomy-cota,Monoblepharomycota,Mortierellomycota,Mucoromycota,Neocallimastigomycota,Olpidiomycota,Rozellomycota and Zoopagomycota.Thus,611 genera in 153 families,43 orders and 18 classes are provided with details of classification,synonyms,life modes,distribution,recent literature and genomic data.Moreover,Catenariaceae Couch is proposed to be conserved,Cladochytriales Mozl.-Standr.is emended and the family Nephridiophagaceae is introduced.
