Land use scenario simulation of mountainous districts based on Dinamica EGO model

Mountainous area makes up 22% of global land, and rational land use in this area is important for sustainable development. Mentougou district has been positioned as an ecological conservation development zone of Beijing and significant land use changes have taken place since 2004. With the combination of GIS and Dinamica EGO(Environment for Geoprocessing Objects) model, the quantitative structure and spatial distribution of land use in Mentougou from 2006 to 2014 are analyzed in this paper. Considering topography has influence on the action mode of driving factors, the research area is divided into two parts based on elevation, mountainous area above 300 m, plain and shallow mountainous area below 300 m. Based on cellular automata theory, the probability of land use change is calculated by Weights of Evidence method and the spatial distribution of land use is simulated by means of two complementary spatial transition functions: Expander and Patcher. Land use pattern of Menougou in 2030 for three kinds of scenarios: trend development, rapid development and ecological protection are simulated. The comparison shows that the trend development scenario is more reasonable based on social, economic and environmental considerations and other scenarios provide a reference for improving irrational land use.

Through the lenses of Sigmund Freud'id, ego, and superego,it will be demonstrated that how she succeeds in balancing these three psychological elements, and making her spiritual development and transformation.

The Old Man-the Real Winner in the Struggle Between Ego and Superego

The Old Man and the Sea was an excellent novel written by the famous American novelist Ernest Hemingway and the novel led to the Nobel Prize which he won in 1954.The novel is a simple story about a Cuban fisherman Santiago's struggle with a marlin and sharks on the sea.In fact it has deep meaning,which implies the struggle between one's ego and superego.Hemingway eulogizes the hero through the process of the struggle.The paper consists of three parts.The first part is the introduction to the writer and the novel.The second part analyzes the hero Santiago in details,including his struggle with the marlin and the sharks,his interest in the struggles.The third part is the conclusion that the hero Santiago's superego controls his ego in the struggle and he is a real winner.

Balance of Internal Drive, Ego and Super Ego through Self-Hypnosis

The paper discusses about the influence of Self-Hypnosis on the three important qualities determining the personality trait of an individual namely: Internal Drive (ID), Ego and Super Ego. Self-Hypnosis is a technique that regulates one’s own mind by setting attributes to achieve the basic goals in life having a wider range of variation from one individual to another. There is a constant conflict occurring in an individual’s mind between ID, Ego, and Super Ego throughout his life time till death. The paper work attempts to bring certain facts about the ID, Ego and Super Ego and how to balance between the three through Self-Hypnosis.

Ego strength and health: An empiric study in hemodialysis patients

Introduction: Ego strength represents an important variable that could be predictable about health and compliance in chronic diseases. In this study we propose a new questionnaire, E.F.E. “Ego Functioning Experience”, able to reveal the psychological functioning profile in Hemodialysis patients. The aim of this work, is to underline the existing relations between emotional profile and compliance, whit E.F.E., that may be predictive of a state of psychologycal health in hemodialysis patients. Methods: Study population included 90 hemodialysis patients. The study protocol was made by three psychological tests: the E.F.E. Questionnaire, the DMI, the Self-Liking and Self-Competence Scale. Results: Factor analysis extracts three factors: 1) “Need of Ego support”;2) “Ego activity oriented to treatment”;3) “Ego strength”. The correlation coefficients between the E.F.E. Questionnaire factors (three factors) and other measures, showed a direct correlation with the first factor and “turning against object” TAO of the DMI test (correlation is significant at the 0.001 level) and an inverse relation with set mechanisms of “Principalization”, PRN of the DMI (correlation is significant at the 0.005 level). The correlations of the second and the third factors with other measures, were not statistically significant. No relations were found about other variables. Conclusions: The E.F.E. questionnaire is a simple evaluation to detect hemo-dialysis patients who may need greater attention to the psychological health and therefore the need for treatment such as psychological support. In fact, lower presence of ego strength is indicative of poor compliance to clinical treatment in hemodialysis, but also of worsening of psychiatric symptoms such as demoralization and depressed mood. In conclusion, an increased social support is needed in hemodialysis patient in order to achieve better compliance and achieve a better state of psychological health in chronic hemodialysis patients.

Associations between the Rorschach Ego Impairment Index and Measures on Intrapsychic and Interpersonal Functioning

The Rorschach Ego Impairment Index-2 (EII-2) has shown considerable validity as a measure of personality disturbance. However, few studies have been conducted on the associations between the EII-2 and measures related to ego strength and interpersonal capacities in mood and anxiety disorder patients. This study examined the strength of associations between the EII-2 and its subcomponents with measures of psychological suitability for psychotherapy, personality functioning, and interpersonal problems. A total of 315 outpatients with mood or anxiety disorders were assessed with the Rorschach Comprehensive System (RCS), comprising the EII-2, the Suitability for Psychotherapy Scale (SPS), the Inventory of Interpersonal Problems (IIP-64), and the Quality of Object Relations Scale (QORS), as part of a pre-treatment evaluation. The relatively weak associations found in the study between the EII-2 and the other measures were mostly in the hypothesized direction and often modified by personality pathology. Of the EII-2 subcomponents, the Good Human Representation (GHR) variable was associated with the SPS. The subcomponent Critical Contents were associated with the IIP and the subcomponent WSum6 with the IIP and QORS. Further research is needed to clarify whether the EII-2 has incremental validity in predicting the treatment outcome and alliance in comparison to interview-based and self-report measures.

“For the Wood Wakes, and You are Here for Proof”——On the Dialectics of the Ego Construction in Frostian Woods

In Into My Own and My Dream Pang written by Robert Frost,there are two sides in the subject that are at odds with each other:the one that wants to retreat from the worldly matters and the other that calls for others’communication with him.By adopting the psychoanalytic theory of Sigmund Freud and Jacques Lacan,this paper finds that the protagonist’s implicit need for the recognition from others plays a defining role in the construction of his new identity as a hermit.

基于并行EGO和代理模型辅助的多参数优化方法研究

化工流程模拟优化问题常常具有高维、非线性的特点,使得仿真计算难以收敛。过长的求解时间是调度优化和运行优化的主要瓶颈之一。采用代理模型对机理模型进行替代是降低计算复杂度、保证结果准确性的有效途径。Kriging代理模型具有较强的非线性近似性,但处理高维问题依然较为困难。因此,本文研究并行EGO(efficient global optimization)算法与代理模型集成,并将模型应用于化工过程。并行EGO算法以Kriging代理模型的预测函数和误差函数为基础,先推导出样本分布概率密度函数与累积分布函数相结合的解析表达式;然后通过PEI(pseudo expected improvement)准则得到新的样本点以更新代理模型;最后结合改进的差分进化算法对优化参数进行全局搜索。在保证结果准确性的前提下,将本文算法与其他优化算法进行比较。8个多峰测试函数的测试结果表明,该算法的收敛速度提高了85%。然后将其应用于双级氨吸收制冷过程的模拟,结果表明该方法的模拟误差小于0.01%,优化时间从9846 s缩短至3705 s。

A Novel Ego Lanes Detection Method for Autonomous Vehicles

Autonomous vehicles are currently regarded as an interesting topic in the AI field.For such vehicles,the lane where they are traveling should be detected.Most lane detection methods identify the whole road area with all the lanes built on it.In addition to having a low accuracy rate and slow processing time,these methods require costly hardware and training datasets,and they fail under critical conditions.In this study,a novel detection algo-rithm for a lane where a car is currently traveling is proposed by combining simple traditional image processing with lightweight machine learning(ML)methods.First,a preparation phase removes all unwanted information to preserve the topographical representations of virtual edges within a one-pixel width around expected lanes.Then,a simple feature extraction phase obtains only the intersection point position and angle degree of each candidate edge.Subsequently,a proposed scheme that comprises consecutive lightweight ML models is applied to detect the correct lane by using the extracted features.This scheme is based on the density-based spatial clustering of applications with noise,random forest trees,a neural network,and rule-based methods.To increase accuracy and reduce processing time,each model supports the next one during detection.When a model detects a lane,the subsequent models are skipped.The models are trained on the Karlsruhe Institute of Technology and Toyota Technological Institute datasets.Results show that the proposed method is faster and achieves higher accuracy than state-of-the-art methods.This method is simple,can handle degradation conditions,and requires low-cost hardware and training datasets.

加速DACE的EGO算法

在函数最优点求解问题中,如果函数表达式很复杂(或黑箱问题),很难利用常用的优化算法求解全局最优点。这时需要先用插值或拟合函数去逼近原函数,然后对新的逼近函数求最优点,进而得到原函数的最优点。基于上述思想,Jones等人于1989提出了EGO(Efficient Global Optimization)算法。EGO算法不足之处在于:它浪费了一个采样点判断EGO算法是否满足终止条件,寻求EI最大值点的收敛速率不高,算法终止条件选择不佳,不能保证估计值的最小点(即EI最大值点)是原函数的内点。针对EGO算法的不足之处,提出了改进的加速EGO算法。仿真实验表明,SEGO极大地节省了运算时间,并且能获得任意精度的全局最优点。

The Struggling Egos in a Harsh Society

As social beings, men can not avoid being affected by the dominant ideologies of their time. At the same time, asanimals with intellect, they inevitably have their own passions and thoughts. When thrown into a society, they will constantly findthemselves tortured by their natural self and their social consciousness. In the face of such a conflict, ego, which refers to therational, thoughtful and realistic personality process, plays its part in meditating the conflict. By discussing briefly the three maincharacters’ struggling egos in The Scarlet Letter, we can see clearly that Nathaniel Hawthorne’s work reflects the above fact. heholds that man is not able to escape the influence of the society, on the other hand, he is not the least dismayed at human beings’comparative mental freedom.

The Imbalance and Spilt of Personality——A Psychoanalytic Analysis of Macbeth's downfall

Macbeth is one of Shakespeare's great tragedies, and it is also famous for vivid psychological description. It mainly portrays the downfall of Macbeth who transforms from a brave hero with nobility and loyalty to a ruthless demon with the interaction of the internal and external causes. This paper tries to find a reasonable explanation for his downfall by adopting the theories of Freudian psychoanalysis, and further reveal the desire's erosion to the conscience and morality's restraint to the desire in human nature. The id,the ego and the superego interact with each other. If any one of them is in imbalance with another,serious personality imbalance,or even personality split will occur.
