Theoretical Analyses

Some mathematical models have been proposed for theoretical analyses of genetic algorithms (GAs). However, these works have limited their objects to a few kinds of GAs in order to formulate them accurately. In this paper, we regard a GA as an information source that generates input-output data. That is, we regard a population and its next population generated by the GA as input and output respectively. Then we model the GA by learning from these data. Since this method uses only the input-output relations of data and ignores interior structures, we can describe a variety of GAs in a common form, and analyze them from a new point of view. We use some mixture models for a representation of these input-output relations in this paper. By using a mixture model for modeling a GA, we can represent the GA system as a combination of some partial systems. In this paper, we treat two types of mixture models, and investigate how these models are effective for analyzing GAs through some numerical experiments.

Point of Sales application is a system used for transaction data into the database both by input and output, so that there are no errors in input, output data, and report generation based on the corresponding data, thus it can produce accurate output data. PT Esensi Solusi Buana is a company engaged in the field of technology and information. Based on surveys and interviews with clients of PT Esensi Solusi Buana, it is obtained the information about the operating system that is still manual and less than optimal.This causes frequent errors in recording sales transaction data, archiving that still uses the traditional system, as well as access to obtain information about the transaction history that requires a lot of time. Therefore, the system to be made is an improvement of the system that was previously made for the clients of PT Esensi Solusi Buana. It is expected that with this system, it can minimize errors that may occur. This system is also expected to be able to improve the process of input, output, and report generation, which in turn can help data collection of sales transactions on the clients of PT Esensi Solusi Buana

Input-output tables with input-output data represent a relatively simple but useful tool to analyze the structure of the economy or undergoing structural changes. These tables enable to quantify direct and indirect linkages within each economy, as well as to study demand or supply relationships between particular sectors. The aim of this paper is to present and compare the main characteristics of 2 selected sectors for Slovakia and Austria. The focus is on the agriculture and food sector and their characteristics using the input output data and analysis. We compared basic input and output multipliers in order to verify the similarities in the position and the development of these sectors in selected countries. Other objectives were analysis of sectors’ backward and forward linkages, “measuring” of their strengths, the identification of key industries and concentration of their impacts. With accordance to our previous research and general trends, we expected a certain decline of importance over the analyzed period of 2000-2014.

Data Scheme

The laboratory side of a digital dental workflow consists of heterogeneous software tools including digitization (scanning), modeling (CAD), production planning (CAM) and production. The heterogeneity can be structured in two dimensions: ‘various partial systems’, composing the dental product development system and ‘various vendors’, offering software solutions for these partial systems. As a result the value creation process lacks efficiency and different input/output data streams are still necessary. As a standard for the representation of geometric data the STL format has been established, whereas for additional information, such as organizational and administrative data, as well as requirements and design data, the XML (eXtensible Markup Language) format is considered appropriate. However, a variety of proprietary XML data formats have been developed by system vendors. Thus incompatibilities are a significant source for errors. Data flow structures as available today only allow unidirectional flow of information ‘downstream’. A new approach is based on a federative workflow data management. The basic concept is a unified XML scheme that represents data about all activities and states of dental objects created throughout the whole cycle of dental process. The new unified XML scheme provides a data structure, which can be adapted for the respective input/output data streams of all partial systems. The XML scheme represents a unified data scheme which allows both vertical (within a certain partial system class) and horizontal (along the digital dental workflow and independent of system vendor) data usage. Each dental system supplier only needs to create one input and output filter for the neutral XML interface. The system architecture is based on a web server to which a XML database server is connected. The XML database server manages project specific XML databases. Data can be made available through REST-, as well as through WebDAV-interface on LAN or WAN. With the help of XPath and XQuery required data can be extracted from the database. Redundant data input as well as incompatibility errors can be avoided by this approach. The innovative core is a unified workflow data format, in which a bidirectional data flow can be provided for both downstream and upstream, along the digital dental workflow.

AbstractSilicification and illitization due to diagenesis result in the modification of porosity and permeability in many North Sea reservoirs, including Greater Alwyn. A good estimation of the mineral composition is required as input/output data for geochemical modelling modes intended to reproduce these effects. Using sedimentological studies to determine laterally equivalent facies, three facies were chosen. ‘Initial states’ for modelling were thus defined as the present-day composition of less-evolved laterally-equivalent facies, ‘final states’ as the present-day composition in the most evolved part of the basin. Precise actual mineral compositions were calculated using a reconciliation program, DATREC. Average compositions calculated for each facies in each field provided data useful in constraining input/output values used in modelling, and gave insights into depositional variation. Arithmetic tests assuming isochemical transformations, constraining the chemical compositions of ‘initial states’ to fit actual mineralogical compositions of ‘final states’, were run using this software. They show that, from an arithmetical point of view, if the assumption of equivalent facies holds, isochemical reactions can occur in some, but not in all facies, thereby demonstrating the importance of checking equivalence of facies and diagenesis hypotheses by quantitative calculations.

Abstract Rank-deficiencies and ill-conditioning of the synthesis matrix in the optimization of function-generating linkages are often caused by an improper selection of the input-output data points given by the {ψi,ϕi}1m pairs, where ψ and ϕ denote the input and output values, respectively. Ten basic cases of rank-deficiencies in the synthesis matrix are discussed in this paper, the associated curves, termed singularity curves, being plotted in the ψ-ϕ plane. Measures to remedy the ill-conditioning that arises in the optimization procedure and means to find the best-conditioned synthesis matrices by minimizing their condition number are also proposed.

Background Risks

Background, or systematic, risks are integral parts of many systems and models in insurance and finance. These risks can, for example, be economic in nature, or they can carry more technical connotations, such as errors or intrusions, which could be intentional or unintentional. A most natural question arises from the practical point of view: is the given system really affected by these risks? In this paper we offer an algorithm for answering this question, given input-output data and appropriately constructed statistics, which rely on the order statistics of inputs and the concomitants of outputs. Even though the idea is rooted in complex statistical and probabilistic considerations, the algorithm is easy to implement and use in practice, as illustrated using simulated data.

Arable Land Use

In the rapid process of urbanization in China, arable land resources are faced with dual challenges in terms of quantity and quality. Starting with the change in the coupling coordination relationship between the input and output on arable land, this study applies an evaluation model of the degree of coupling coordination between the input and output (D_CCIO) on arable land and deeply analyzes the recessive transition mechanism and internal differences in arable land use modes in 31 provinces on mainland China. The results show that the total amount and the amount per unit area of the input and output on arable land in China have presented different spatio-temporal trends, along with the mismatched movement of the spatial barycenter. Although the D_CCIO on arable land increases slowly as a whole, 31 provinces show different recessive transition mechanisms of arable land use, which is hidden in the internal changes in the input–output structure. The results of this study highlight the different recessive transition patterns of arable land use in different provinces of China, which points to the outlook for higher technical input, optimized planting structure, and the coordination of human-land relationships.
