Direct Heat Integration of Independent Processes

The properties of matched streams, the simultaneous operation time, and the distance between integrated processes, are the main factors which determine whether the direct integration is feasible or not. According to whether such synthetic integration is economically better than the separate integration of each process, a mathematical formulation is established. The retrofit of reforming and arene processes in a certain petrochemical factory, which are independent each other, is chosen as a case study. By only considering the simultaneous operation time, two retrofit designs are proposed: one is that each of the two processes is separately integrated by itself, and the other is that the two processes are integrated comprehensively. Under different simultaneous operation hours, the energy-saving effects and the economic profits of the two designs are calculated, and furthermore, the critical simultaneous operation time for direct heat integration of the two processes is obtained. When the actual simultaneous operation time of the two processes is longer than the critical value, the direct heat integration of the two processes is better economically, and otherwise the separate heat integration for each process should be considered.

Research and Practice of the “Independence + Integration” Moral and Self-cultivation Teaching Method for Online Specialized Courses

In the context of the COVID-19 outbreak,online teaching has spread rapidly.However,the existing research on moral and self-cultivation teaching methods for online courses remains inadequate.This paper proposes an“independence+integration”moral and self-cultivation teaching method for online courses.The method divides the targets of moral and self-cultivation teaching into independent and integrated ones,and fits them both explicitly and implicitly into the online teaching of specialized courses in higher education.When this method was employed to teach engineering mechanics to industrial design students at a college in China,it effectively increased the students’acceptance of online courses as well as their understanding of moral and self-cultivation knowledge and the course itself,and improved the quality of online teaching.The method provides a new way of thinking about online moral and self-cultivation teaching.

Process Monitoring Based on Independent Component Contribution

Independent component analysis( ICA) has been widely applied to the monitoring of non-Gaussian processes. Despite lots of applications,there is no universally accepted criterion to select the dominant independent components( ICs). Moreover, how to determine the number of dominant ICs is still an open question. To further address this issue,a novel process monitoring based on IC contribution( ICC) is proposed from the perspective of information storage. Based on the ICC with each variable,the dominant ICs can be obtained and the number of dominant ICs is determined objectively. To further preserve the process information, the remaining ICs are not useless. As a result,all the ICs are regarded to be divided into dominant and residual subspaces. The monitoring models are established respectively in each subspace, and then Bayesian inference is applied to integrating monitoring results of the two subspaces. Finally, the feasibility and effectiveness of the proposed method are illustrated through a numerical example and the Tennessee Eastman process.

On Some Fundamental Integrodifferential Inequalities

Multidisciplinary integrated design of long-range ballistic missile using PSO algorithm

In the case of the given design variables and constraint functions, this paper is concerned with the rapid overall parameters design of trajectory, propulsion and aerodynamics for long-range ballistic missiles based on the index of the minimum take-off mass.In contrast to the traditional subsystem independent design, this paper adopts the research idea of the combination of the subsystem independent design and the multisystem integration design.Firstly, the trajectory, propulsion and aerodynamics of the subsystem are separately designed by the engineering design, including the design of the minimum energy trajectory, the computation of propulsion system parameters, and the calculation of aerodynamic coefficient and dynamic derivative of the missile by employing the software of missile DATCOM. Then, the uniform design method is used to simplify the constraint conditions and the design variables through the integration design, and the accurate design of the optimized variables would be accomplished by adopting the uniform particle swarm optimization(PSO) algorithm. Finally, the automation design software is written for the three-stage solid ballistic missile. The take-off mass of 29 850 kg is derived by the subsystem independent design, and 20 constraints are reduced by employing the uniform design on the basis of 29 design variables and 32 constraints, and the take-off mass is dropped by 1 850 kg by applying the combination of the uniform design and PSO. The simulation results demonstrate the effectiveness and feasibility of the proposed hybrid optimization technique.

An extended J-integral for evaluating fluid-driven cracks in hydraulic fracturing

J-integral has served as a powerful tool in characterizing crack tip status. The main feature, i.e. path- independence, makes it one of the foremost fracture parameters. In order to remain the path- independence for fluid-driven cracks, J-integral is revised. In this paper, we present an extended J-in- tegral explicitly for fluid-driven cracks, e.g. hydraulically induced fractures in petroleum reservoirs, for three-dimensional （3D） problems. Particularly, point-wise 3D extended J-integral is proposed to char- acterize the state of a point along crack front. Besides, applications of the extended J-integral to porous media and thermally induced stress conditions are explored. Numerical results show that the extended J- integral is indeed path-independent, and they are in good agreement with those of equivalent domain integral under linear elastic and elastoplastic conditions. In addition, two distance-independent circular integrals in the K-dominance zone are established, which can be used to calculate the stress intensity factor （SIF）.

Developing Integrated Collective Bargaining System in a Bi National Organization:The Case of the Tanzania Zambia Railway Authority(TAZARA)

The Tanzania Zambia Railway stretches 1,860 kilometers from the East African Indian Ocean port of Dar es Salaam in Tanzania to New Kapiri-Mposhi in land locked Zambia.It is defined as a bi-national organization as opposed to either transnational or multinational because it is jointly owned and managed by the Governments of Tanzania and Zambia.Its construction was made possible by Chinese interest-free loan to the two Governments.Few development projects in Africa have been charged with as much political and ideological dynamite as Tanzania Zambia Railway.To the Western powers,angry that the Chinese had entered territory which they considered their own preserve,it was a Red Railway intended to thrust communism into the very heart of Africa.For the white regimes in Southern Africa,grimly attempting to hold back demands for majority rule,it was seen as Africa’s Ho Chi Minh Trail,carrying guerrilla further,armed with Chinese thoughts and weapons to the banks of the Zambezi River.The Chinese regarded the project as a Friendship Route to strengthen the new African states against the forces of imperialism and for Tanzania and Zambia it was a Freedom Railway,which should prove an instrument in increasing their independence.These reactions underpin not only the complexity of the establishment and management of a bi-national organization but also present challenges to the two national trade unions on how best they can represent their members.Industrial relations literature has cited differences in countries’historical,social,political,economic,and ideological background as the main obstacles in the development of collective bargaining machinery in transnational or multinational organizations.A study in Tanzania Zambia Railway Authority has attempted to develop an integrated bi-national collective bargaining machinery whose collective agreements are likely to be legally enforceable in their respective countries.This paper explores the development of trade unions in both Tanzania and Zambia which can be divided in three phases:first,the construction phase;second,the consolidation phase;and the third and final phase,trade union liberalization and political pluralism which covers the development of a bi national collective bargaining model with its Joint Industrial Council structure and negotiation procedures.The paper compares and contrasts trade union development in the two contracting states and critically examines how each phase has influenced trade union development.It provides a brief historical outline of collective bargaining process and spells out advantages and limitations of bi-national collective bargaining machinery.The paper concludes by observing that one of the main objectives of regional groupings is economic integration and suggests that integrated collective bargaining machinery be adopted as an ideal industrial relations model for regional groupings such as the African Union(AU),Southern African Development Community(SADC),Common Market for Eastern and Southern Africa(COMESA),Economic Community for West African States(ECOWAS),Eastern African Community,and other regional groupings around the world since it localizes industrial relations function in general and collective bargaining in particular.

Revised BDS test

In this paper,we focus on the BDS test,which is a nonparametric test of independence.Specifically,the null hypothesis H0 of it is that {u_(t)} is i.i.d.(independent and identically distributed),where {u_(t)} is a random sequence.The BDS test is widely used in economics and finance,but it has a weakness that cannot be ignored:over-rejecting H0 even if the length T of {u_(t)} is as large as(100;2000).To improve the over-rejection problem of BDS test,considering that the correlation integral is the foundation of this test,we not only accurately describe the expectation of the correlation integral under H_(0),but also calculate all terms of the asymptotic variance of the correlation integral whose order is O(T^(-1))and O(T^(-2)),which is essential to improve the finite sample performance of BDS test.Based on this,we propose a revised BDS(RBDS)test and prove its asymptotic normality under H0.The RBDS test not only inherits all the advantages of BDS test,but also effectively corrects the over-rejection problem of it,which can be fully confirmed by the simulation results we presented.Moreover,based on the simulation results,we find that similar to BDS test,RBDS test would also be affected by the parameter estimations of the ARCH-type model,resulting in size distortion,but this phenomenon can be alleviated by the logarithmic transformation preprocessing of the estimate residuals of the model.Besides,through some actual datasets that have been demonstrated to fit well with ARCH-type models,we also compared the performance of BDS test and RBDS test in evaluating the goodness-of-fit of the model in empirical problem,and the results reflect that,under the same condition,the performance of the RBDS test is more encouraging.

A Class of Robust Independence Tests Based on Weighted Integrals of Empirical Characteristic Functions

In this paper,we propose a class of robust independence tests for two random vectors based on weighted integrals of empirical characteristic functions.By letting weight functions be probability density functions of a class of special distributions,the proposed test statistics have simple closed forms and do not require moment conditions on the random vectors.Moreover,we derive the asymptotic distributions of the test statistics under the null hypothesis.The proposed testing method is computationally feasible and easy to implement.Based on a data-driven bandwidth selection method,Monte Carlo simulation studies indicate that our tests have a relatively good performance compared with the competitors.A real data example is also presented to illustrate the application of our tests.

“纪法融合”视域下监察法学知识体系的价值取向及建构逻辑

随着纪检监察实践和研究不断深入及纪检监察学成为一级学科,学界需要重新讨论监察法学的学科定位,以及围绕学科属性展开新的知识体系建构。党和国家权力监督目的的一致性、“纪法相融”的学科思维以及纪检监察合署办公的行权模式决定了监察法学应作为纪检监察学的二级学科进行知识生产。在权力监督研究价值取向多元化的背景下,监察法学知识体系建构应选择以人民性为前提的政治性与法治性相结合的价值取向。监察法学必须在党和国家权力监督体系同构的前提下强化知识生产创新能力,加强知识供给,变革知识生产方式,完善学科内部结构,有效回应监察实践的现实需要。
