Greedy algorithms for high-dimensional eigenvalue problems

In this article, we present two new greedy algorithms for the computation of the lowest eigenvalue (and an associated eigenvector) of a high-dimensional eigenvalue problem, and prove some convergence results for these algorithms and their orthogonalized versions. The performance of our algorithms is illustrated on numerical test cases (including the computation of the buckling modes of a microstructured plate), and compared with that of another greedy algorithm for eigenvalue problems introduced by Ammar and Chinesta.Comment: 33 pages, 5 figure

Representación en torno a la concepción de trabajo : los casos de AMMAR CTA y AMMAR Capital

Background of INCASI Project H2020-MSCA-RISE-2015 GA 691004. WP1: CompilationEste artículo aborda la problemática de la prostitución a través del estudio de las representaciones sobre el trabajo que tienen integrantes de las organizaciones Ammar CTA (Asociación de Mujeres Meretrices Argentinas) y Ammar Capital (Asociación de Mujeres Argentinas por los Derechos Humanos). Consideramos que la prostitución es una forma de reproducción material para muchas mujeres y, a partir de ello, se esgrimen diferentes representaciones sobre esta actividad. En el artículo desarrollamos los posicionamientos que sostienen las integrantes de estas dos organizaciones frente a la concepción de trabajo y de la prostitución como trabajo, destacando principalmente las continuidades y rupturas entre ellas

Taking the Punishment Out of the Process: From Substantive Criminal Justice Through Procedural Justice to Restorative Justice

If the punishment is taken out of the process, and the processes of criminal justice become effective at restoration--and if rigorous empirical research might show that a restorative process costs less money and produces greater public safety--that would be a result everyone would embrace

THE EFFICIENCY EXTENT OF THE INTERNAL CONTROL ENVIRONMENT IN THE PALESTINIAN HIGHER EDUCATIONAL INSTITUTIONS IN GAZA STRIP

The purpose of this research is to identify the extent of the efficiency of the internal control environment in the Palestinian higher educational institutions in Gaza Strip from the perspective of employees in the Palestinian universities in Gaza Strip, where researchers used in the study five universities. The researchers adopted in their study the descriptive and analytical approach. The research community consists of administrative employees and academic employees with administrative duties. Senior management or the University Council was excluded. The study population compromises of (392) employees. A stratified random sample was chosen and (197) questionnaires were distributed. (160) questionnaires were received back with a return rate of (81.2%).The researchers used a questionnaire to collect that which then was analyzed using (SPSS) to get the results. The research found the following results: the absence of a fundamental difference between the responses of males and females. The lack of significant difference between the responses of the respondents attributed to the variable age. The lack of significant difference between the responses of the respondents attributed to the variable of years of service. And the existence of a fundamental difference between the responses of the respondents attributed to the university variable. The existence of a fundamental difference between the responses of the respondents attributed to the Qualification variable. The existence of a fundamental difference between the responses of the respondents attributed to the administrative level variable. The research found a group of recommendations including: the need to raise awareness of censorship as the basis for the protection of employees in all administrative levels from making mistake.Updating the systems and instructions of control periodically and parallel with the scientific progress and technology.Benefit from regional and international experiences in the application of internal control standards which commensurate with the administrative system of the institution

A Simple Quantum Neural Net with a Periodic Activation Function

In this paper, we propose a simple neural net that requires only $O(nlog_2k)$ number of qubits and $O(nk)$ quantum gates: Here, $n$ is the number of input parameters, and $k$ is the number of weights applied to these parameters in the proposed neural net. We describe the network in terms of a quantum circuit, and then draw its equivalent classical neural net which involves $O(k^n)$ nodes in the hidden layer. Then, we show that the network uses a periodic activation function of cosine values of the linear combinations of the inputs and weights. The backpropagation is described through the gradient descent, and then iris and breast cancer datasets are used for the simulations. The numerical results indicate the network can be used in machine learning problems and it may provide exponential speedup over the same structured classical neural net.Comment: a discussion session is added. 5 pages, conference paper.

Stoning in Iran: A Sexist and Overlooked Practice

This paper seeks to dissect and expose the ancient practice of stoning in Iran, and to analyze the injustices that are built into this punishment

Developing an Overbooking Fuzzy-Based Mathematical Optimization Model for Multi-Leg Flights

Overbooking is one of the most vital revenue management practices that is used in the airline industry. Identification of an overbooking level is a challenging task due to the uncertainties associated with external factors, such as demand for tickets, and inappropriate overbooking levels which may cause revenue losses as well as loss of reputation and customer loyalty. Therefore, the aim of this paper is to propose a fuzzy linear programming model and Genetic Algorithms (GAs) to maximize the overall revenue of a large-scale multi-leg flight network by minimizing the number of empty seats and the number of denied passengers. A fuzzy logic technique is used for modeling the fuzzy demand on overbooking flight tickets and a metaheuristics-based GA technique is adopted to solve large-scale multi-leg flights problem. As part of model verification, the proposed GA is applied to solve a small multi-leg flight linear programming model with a fuzzified demand factor. In addition, experimentation with large-scale problems with different input parameters’ settings such as penalty rate, show-up rate and demand level are also conducted to understand the behavior of the developed model. The validation results show that the proposed GA produces almost identical results to those in a small-scale multi-leg flight problem. In addition, the performance of the large-scale multi-leg flight network represented by a number of KPIs including total booking, denied passengers and net-overbooking profit towards changing these input parameters will also be revealed

Finding a consensus between philosophy of applied and social sciences: A case of biology of human rights

This paper is an attempt to provide an adequate theoretical framework to understand the biological basis of human rights. We argue that the skepticism about human rights is increasing especially among the most rational, innovative and productive community of intellectuals belonging to the applied sciences. By using examples of embryonic stem cell research, a clash between applied scientists and legal scientists cum human rights activists has been highlighted. After an extensive literature review, this paper concludes that the advances in applied sciences proven by empirical evidence should not be restricted by normative theories and philosophies of the social sciences. If we agree on these premises that Human Rights are biological, then biology can provide a framework of cooperation for social and applied scientists
