Game Theory Based Model for Predictive Analytics Using Distributed Position Function

This paper presents a game theory-based method for predicting the outcomes of negotiation and group decision-making problems. We propose an extension to the BDM model to address problems where actors’ positions are distributed over a position spectrum. We generalize the concept of position in the model to incorporate continuous positions for the actors, enabling them to have more flexibility in defining their targets. We explore different possible functions to study the role of the position function and discuss appropriate distance measures for computing the distance between the positions of actors. To validate the proposed extension, we demonstrate the trustworthiness of our model’s performance and interpretation by replicating the results based on data used in earlier studies.

Density Function Theory Study on Effects of Different Energetic Substituent Groups and Bridge Groups on Performance of Carbon-Linked Ditetrazole 2N-Oxides

Based on the parent tetrazole 2N-oxide, six series of novel carbon-linked ditetrazole 2N- oxides with different energetic substituent groups （-NH2, -Na, -NO2, NF2, -NHNO2） and energetic bridge groups （-CH2-, -CH2-CH2-, -NH-, -N=N-, -NH-NH-） were designed. The overall performance and the effects of different energetic substituent groups and energetic bridge groups on the performance were investigated by density functional theory and electrostatic potential methods. The results showed that most of designed compounds have oxygen balance around zero, high heats of formation, high density, high energy, and acceptable sensitivity, indicating that tetrazole N-oxide is a useful parent energetic compound employed for obtaining high energy compounds, even only combined with some very common energetic substituent groups and bridge groups. Comprehensively considering the effects on energy and sensitivity, the -NO2, -NF2, -NH- and-NH-NH- are appropriate substituent groups for combining tetrozale N-oxide to design new energetic compounds, while -NH2, -Na, -CH2-CH2-, and -N=N- are inappropriate.

Optimization of Grouping Evacuation Strategy in High-rise Building Fires Based on Graph Theory and Computational Experiments

It is difficult to rescue people from outside, and emergency evacuation is still a main measure to decrease casualties in high-rise building fires. To improve evacuation efficiency, a valid and easily manipulated grouping evacuation strategy is proposed. Occupants escape in groups according to the shortest evacuation route is determined by graph theory. In order to evaluate and find the optimal grouping, computational experiments are performed to design and simulate the evacuation processes. A case study shown the application in detail and quantitative research conclusions is obtained. The thoughts and approaches of this study can be used to guide actual high-rise building evacuation processes in future.

Strategic group theory： A customer-oriented view

Barney and Hoskisson （1990） argue that the strategic group research has neither established the existence of strategic groups, nor their relationship to firm performance. The primary reason behind the unsatisfactory results is the lack of a theoretical framework： what strategic variables to include in the analysis and their relative importance; the definition of an industry, and how to make competitive strategy operational. First, the author presents a customer-oriented theory of management which submits that, like Procter and Gamble, understanding customers should be the primary focus of a business. Second, the author proposes an integrated approach to competitive strategy. Because customer-perceived quality is far more critical to long-term success than any other factor, it should be the centerpiece of competitive strategy. The author suggests that competitive strategy should be divided in two interdependent dimensions： external and internal. It is the external strategy that should be considered the primary dimension because it reflects the customers＇ perspective, and provides a sense of direction regarding how the internal resources should be used. Next, the author presents an operational framework of competitive strategy which proposes that the best route to market share leadership in consumer markets is competing in the mid-price segment, offering superior quality compared to competition at a somewhat higher price： （1） to maintain an image of quality, and （2） to ensure that the strategy is profitable and sustainable. Finally, the author offers a framework of business or industry definition that extends Abell＇s （1980） three dimensions to seven. He suggests that an integrated approach to market segmentation provides the foundation for conducting strategic group analysis in consumer markets. So, in strategic group research, we need a bottom-up approach that begins with a product-market segment. In each product market, real competition occurs at the brand level. This is the ground where actual competitive wars are fought, and this is where the rich dynamics of competition often come to light.

A New Group Theoretical Approach to the Nonorthogonal Problem in Valence Bond Theory

Introduction There has been a very significarnt resurgence of interest in ab initio valence bond calculations recently. This is because the VB calculation based on nonorthogonal basis can provide intuitive understanding about many very important phenomena in chemistry. However, practical calculation based on nonorthogonal basis is still a great challenge even to deal with a quite small system due to the well-known N! (or

New Public Key Cryptosystems from Combinatorial Group Theory

External direct product of some low layer groups such as braid groups and general Artin groups, with a kind of special group action on it, provides a secure cryptographic computation platform, which can keep secure in the quantum computing epoch. Three hard problems on this new platform, Subgroup Root Problem, Multi-variant Subgroup Root Problem and Subgroup Action Problem are presented and well analyzed, which all have no relations with conjugacy. New secure public key encryption system and key agreement protocol are designed based on these hard problems. The new cryptosystems can be implemented in a general group environment other than in braid or Artin groups.

GROUP THEORY ANALYSIS OF MIXED CONVECTION OVER A HORIZONTAL MOVING PLATE

In the present paper, the investigation to the mixed convective boundary layer behavior over a horizontal plate is carried our. By applying transformation group theory, the analysis of the governing equations of continuity, momentum, energy and diffusion shows the existence of similarity solution for the problem provided that the temperature and concentration at the wall are proportional to x(4/(7-5n)) and that the moving speed of the plate is proportional to x((3-n)/(7-5n)), furthermore, a set of similarity equations is obtained. The similarity equations are solved numerically by a fourth-order Runge-Kutta scheme. The numerical results obtained for velocity, temperature and concentration distributions for Pr=0.72 and various values of the parameters Sc, K-1, K-2 and K-3 reveals the influence of these parameters on the flow, and hear and mass transfer behavior.

Secure Passwords Using Combinatorial Group Theory

Password security is a crucial component of modern internet security. In this paper, we present a provably secure method for password verification using combinatorial group theory. This method relies on the group randomizer system, a subset of the MAGNUS computer algebra system and corrects most of the present problems with challenge response systems, the most common types of password verification. Theoretical security of the considered method depends on several results in asymptotic group theory. We mention further that this method has applications for many other password situations including container security.

Diabetes is a chronic disease characterized by hyperglycemia,of which type 2 diabetes mellitus(T2DM)accounts for about 95%[1].In addition,the prevalence of T2DM is still rising,seriously threatening human health.As the mechanism of T2DM is not fully understood,most of the current drugs for the treatment of T2DM focus on lowering blood glucose without solving its underlying problem.This review discusses the application of ginseng-jujube-licorice group in T2DM based on theory of traditional Chinese medicine and research of modern pharmacology,in order to provide a reference for the development of new drugs and future research.

Freud’s Theory and the Group Mind Theory:Formulations

This study aimed to reconsider some concepts of the psychoanalytic theory on group mind. Group psychology is concerned with the individual man as a member of a race, nation, caste, profession, or an institution, or as a component of a crowd of people that has been organized into a group at some particular time, for some specific purpose. Group psychology embraces an immense number of separate issues and offers investigators with countless problems, which have hitherto not even been properly distinguished from one another. Reflections presented in this paper were particularly inspired by Freud’s work on Group psychology and analysis of the ego and approaches to the chaos theory, especially, the fact that groups emerge as systems that exhibit unstable, aperiodic and highly complex behavior, with a tendency to self-organization.

Superior electrocatalytic negative electrode with tailored nitrogen functional group for vanadium redox flow battery

Development of electrodes with high electrocatalytic activity and stability is essential for solving problems that still restrict the extensive application of vanadium redox flow batteries(VRFBs).Here,we designed a novel negative electrode with superior electrocatalytic activity by tailoring nitrogen functional groups,such as newly formed nitro and pyridinic-N transformed to pyridonic-N,from the prenitrogen-doped electrode.It was experimentally confirmed that an electrode with pyridonic-N and nitro fuctional groups(tailored nitrogen-doped graphite felt,TNGF) has superior electrocatalytic acivity with enhanced electron and mass transfer.Density functional theory calulations demonstrated the pyridonic-N and nitro functional groups promoted the adsorption,charge transfer,and bond formation with the vanadium species,which is consistent with expermental results.In addition,the V2+/V3+redox reaction mechanism on pyridonic-N and nitro functional groups was estabilised based on density functional theory(DFT) results.When TNGF was applied to a VRFB,it enabled enhanced-electrolyte utilization and energy efficiencies(EE) of 57.9% and 64.6%,respectively,at a current density of 250 mA cm^(-2).These results are 18.6% and 8.9% higher than those of VRFB with electrode containing graphitic-N and pyridinicN groups.Interestingly,TNGF-based VRFB still operated with an EE of 59% at a high current density of300 mA cm^(-2).The TNGF-based VRFB exhibited stable cycling performance without noticeable decay of EE over 450 charge-discharge cycles at a current density of 250 mA cm^(-2).The results of this study suggest that introducing pyridonic-N and nitro groups on the electrode is effective for improving the electrochemical performance of VRFBs.

Group of Weakly Continuous Operators Associated to a Generalized Schrödinger Type Homogeneous Model

In this work, we prove the existence and uniqueness of the solution of the generalized Schrödinger type homogeneous model in the periodic distributional space P’. Furthermore, we prove that the solution depends continuously respect to the initial data in P’. Introducing a family of weakly continuous operators, we prove that this family is a group of operators in P’. Then, with this family of operators, we get a fine version of the existence and dependency continuous theorem obtained. Finally, we give some remarks derived from this study.

Sociodemographic characteristics, cultural biases, and environmental attitudes: An empirical application of grid-group cultural theory in Northwestern China

Natural resource-management studies have become increasingly attentive to the influences of human factors. Among these,cultural biases shape people’s responses to changes in natural resource systems. Several studies have applied grid-group cultural theory to assess the effects of multiple value biases among stakeholders on natural resource management. We developed and administered a questionnaire in the Heihe River Basin(n = 364) in northwestern China to investigate the appropriateness of applying this theory in the Chinese context of natural resource management. The results revealed various cultural biases among the respondents. In descending order of prevalence, these biases were hierarchism(46.98%), individualism(26.65%), egalitarianism(18.96%), and fatalism(2.78%), with the remaining respondents(4.67%) evidencing no obvious bias. Our empirical study revealed respondents’ worldviews and the influence of sociodemographic characteristics on cultural biases, as theoretically posited. Among the variables examined, age had a positive and significant effect across all biases except individualism. The correlation of income to all cultural biases was consistently negative. Only education had a negative and significant effect across all biases. Women were found to adhere to egalitarianism, whereas men adhered to individualism and hierarchism. Thus, grid-group cultural theory was found to be appropriate in the Chinese context, with gender, age, education, and income evidently accounting for cultural biases. Relationships between environmental attitudes and cultural biases conformed with the hypothesis advanced by grid-group cultural theory. This finding may be of value in explaining individuals’ environmental attitudes and facilitating the development and implementation of natural resource-management policies.

矿工安全行为的群体演化和干预策略研究:基于多智能体仿真分析

随着我国多数矿山企业正实现从“系统智能化”向“智能系统化”的跨越,矿工群体逐渐呈现知识化、年轻化的特征。为推进矿工安全行为管理,结合后悔理论构建了包含情绪反应的矿工安全行为决策模型,并制定了考虑矿工风险偏好异质性的互动规则,通过多智能体仿真的方法,探讨了正念和警示两类事前干预策略下矿工群体安全行为的演化路径。结果表明,仅靠处罚这一事后控制手段并不能有效促进矿工选择安全行为;在事前干预策略中,正念策略比警示策略更有利于促进矿工的安全行为,且这两种策略具有协同效应。此外,矿工之间的互动强度会影响安全行为决策,连结的邻居数量越多,邻居更新越快,矿工会越倾向选择不安全行为。最后,在陕西榆林某矿山企业开展了现场实验,实证检验了正念策略和警示策略对矿工安全行为的激励作用。
