Повний текст джерелаSingle Point Incremental Forming is a recent technology that is currently under development. Its applicability is diverse because it allows the attainment of functional parts in sheet metal without great costs. Due to this characteristic, areas such as biomechanics, rapid prototyping and products of customizable features make this process a target of interest. Unfortunately, the means of obtaining parts using single point incremental forming are limited. Usually, CNC machining centers are utilized but due to their cutting-type characteristics, the implementation of the Single Point Incremental Forming is limited and inefficient. Also, the market supply of dedicated machinery requires high investments, thus becoming an unattractive solution. A major obstacle to the application of this technique focuses on the superior time of forming especially when compared to conventional forming techniques. Another disadvantage of this process is the low dimensional accuracy, however, with the development of numerical studies and correction algorithms this problem tends to be minimized. This work aims to complete the project of a single point incremental forming machine that began in previous years. This project has the objective of overcoming the limitations of the current incremental forming machines, but not ignoring the economic factor. Also, this project aims to enlarge the horizons for future research and development of the process, not only improving the machine but also developing and understanding the forming mechanism and the consequent effects of improved material formability.
A estampagem incremental é um processo recente que está em desenvolvimento. A sua aplicabilidade é variada pois permite a obtenção de peças funcionais em chapa metálica sem grandes custos associados. Devido a esta característica, áreas como a biomecânica, prototipagem rápida e produtos de características personalizáveis fazem deste processo um alvo de interesse. Infelizmente, os meios de obtenção de peças usando estampagem incremental por ponto único são limitados. Normalmente faz-se uso de centros de maquinagem CNC adaptados, que devido às suas características próprias de corte por arranque de apara, tornam a aplicação da estampagem incremental limitada e ineficiente. Além disso, a oferta de mercado em maquinaria com características dedicadas ao uso de estampagem incremental requerem elevados investimentos, tornando-se assim uma solução pouco atractiva. Um dos principais obstáculos à aplicação desta técnica centra-se no tempo de conformação elevado, principalmente quando comparado com técnicas de estampagem convencionais. Outra desvantagem deste processo é a baixa precisão dimensional, que todavia com o avanço dos estudos numéricos e com o desenvolvimento de algoritmos de correcção tende a ser minimizado. Neste trabalho pretende-se concluir o projecto de uma máquina para realização de estampagem incremental por ponto único que teve início em anos anteriores. Este projecto tem por objectivo a obtenção de uma máquina que ultrapasse as limitações das máquinas actuais, mas não desconsiderando o factor económico. Além disso este projecto visa ampliar os horizontes para futuras pesquisas e desenvolvimento do processo, tanto na melhoria da máquina, mas também no desenvolvimento e na compreensão do mecanismo de deformação existente e aumento associado da formabilidade material.

Повний текст джерелаAdvanced development environments are essential for efficient realization of complex industrial products. Powerful equation-based object-oriented (EOO) languages such as Modelica are successfully used for modeling and virtual prototyping complex physical systems and components. The Modelica language enables engineers to build large, sophisticated and complex models. Modelica environments should scale up and be able to handle these large models. This thesis addresses the scalability of Modelica tools by employing incremental compilation and dynamic loading. The design, implementation and evaluation of this approach is presented. OpenModelica is an open-source Modelica environment developed at PELAB in which we have implemented our strategy for incremental compilation and dynamic loading of functions. We have tested the performance of these strategies in a number of different scenarios in order to see how much of an impact they have on the compilation and execution time.
Our solution contains an overhead of one or two hash calls during runtime as it uses dynamic hashes instead of static arrays.

Повний текст джерелаSammanhang De senaste hundra åren har vi gett upphov till att bygga infrastruktur i en snabbare takt än någonsin tidigare. Samtidigt ökar kostnaderna för både arbetskraft och byggsektorer som väg- och bostadsbyggnader. Denna situation ger utrymme för autonoma maskiner. Utvecklingen av infrastruktur sker genom effektiva och produktiva konstruktionsmaskiner som successivt moderniseras för att forma samhället. För att öka utvecklingstakten moderniseras både bilar och industri för att möta en mer automatiserad vardag. Volvo Construction Equipment undersöker det autonoma fordonsutrymmet för nästa generations maskiner. Automationen kompletterar de nya maskinerna och fulländar det mänskliga arbetet med effektivitet, tillförlitlighet och hållbarhet. Det finns dock en fråga om relationen mellan mänskliga arbetare och autonoma maskiner, jag kommer i denna avhandling undersöka metoder för hur man kan utveckla tillit genom kommunikationssystem mellan arbetare och autonoma maskiner. Mål Att skapa rekommendationer och lösningar för produkter som bygger tillit mellan mänskliga och automatiserade maskiner på en byggarbetsplats. Metod Resultatet uppnås genom användandet av fallstudie forskning kombinerat med validerande lärande. Detta innebär lärdomar med hjälp av en iterativ process utav prototyper som testas och valideras. Resultat Resultatet utvärderar hur förtroende kan utvecklas mellan människor och autonoma maskiner på en byggarbetsplats. Hur kommunikationsmetoder mellan dessa parter skulle kunna genomföras samtidigt som hög effektivitet och säkerhet upprätthålls . Slutsats Lärandet i denna avhandling tyder på att förtroendet utvecklas över tid med tillförlitliga system som ger medarbetare uppdaterad nödvändig information tillgänglig när som helst. Resultaten kan införas i både dagens och framtidens anläggningsplatser på olika nivåer av avancerad teknik.

Повний текст джерелаThis thesis is set in a research effort that aims to bring more automation in building mediator-based data integration systems in the semantic Web context. The mediator approach is a conceptual architecture of data integration that involves combining data residing in different sources and providing users with a unified view of these data. The problem of designing effective data integration solutions has been addressed by several researches, and well-known data integration projects have been developed during the 90’s. However, the building process of these systems rely heavily on human intervention so that it is difficult to implement them in many situations. Moreover, faced with the diversity and the increase of available information sources, the easiness and fastness of information access are new challenges. Our proposals are based on models and technologies of semantic web. The semantic web is recognized as a generalization of the current web which enables to find, combine and share resources, not only between humans but also between machines. It provides a good track for automating the integration process. Possibilities offered by the semantic web are based, on the one hand, on languages and an infrastructure aiming to enrich the web with "semantic" information and, on the other hand, on collaborative practices that allow the production of relevant and reusable ontological resources

Purpose: Oxygen uptake (VO2) has been shown to be controlled by a nonlinear system, yet the VO2 response to ramp style exercise appears linear. We tested the hypothesis that an integrative model incorporating nonlinear parameter values could accurately estimate actual VO2 responses to ramp style exercise. Methods: Six healthy, men completed three bouts of varying ramp rate exercise (slow ramp (SR): 15 W/min, regular ramp (RR) 30 W/min, fast ramp (FR) 60W/min) and four bouts of extended-step incremental exercise, where each step lasted 5-15 min or until volitional fatigue on a cycle ergometer on separate days. The step-responses were then fit with a simple monoexponential starting at time zero (MONO) or allowing a time delay and using only the first 5 min of data (5TD). The resulting VO2 parameters from the step protocol were incorporated into an integrative model for the estimation of the VO2 response to each of the rates of ramp incremental exercise. The parameters from the actual and model ramp protocols were compared with 2 way repeated-measures ANOVAs. Results: Both Gain (G) and Mean Response Time (MRT) (or time constant) values increased significantly across work rate transitions (mean±SD; Gain:10.0±0.9, 11.6±1.1, 13.1±1.3, 17.6±3.3 ml O2/min/W; MRT:39.4±7.7, 54.0±5.4, 79.6±15.0, 180.1±56.2 s). Up to maximalVO2 the models over-estimated the actual VO2 response for FR (Gain: ACT 8.7±1.0, MONO 9.9±0.4, 5TD 10.3±0.3 ml O2/min/W). Up to 80% maximal VO2 the models accurately predicted the actual VO2 response across all ramp rates (Gain: ACT 10.7±1.1, 10.2±0.5, 9.2±1.0; MONO 11.0±0.8, 10.3±0.6, 9.2±0.5; 5TD 10.4±0.4, 10.2±0.3, 9.8±0.2 ml O2/min/W, values are listed SR,RR,FR). Conclusions: When variable parameter values (G and either MRT or time constant and time delay) were utilized by an integrative model, accurate estimations of the VO2 response to ramp incremental exercise were possible regardless of ramp rate (up to 80% maximal VO2). The increases in both G and MRT (or time constant) appear to balance each other to produce the quasi-linear VO2 responses.

Повний текст джерелаThis study aims to analyze whether the increased use of wood for housing construction can mitigate carbon dioxide emissions and reduce embodied energy in the civil construction sector in Brazil. The emphasis is on environmental issues, but considers the social and economic fields that may influence the design and effectiveness of public policy. The historical scope was studied to understand wooden housing stock development over the last 40 years as well as the possible factors that may have influenced its percentage decrease in total Brazilian housing stock. The social aspect was explored to learn the public opinion on the use of wood for housing construction, and the strengths and weaknesses of the material in the general society concept. In the economic domain the aim was to characterize the timber sector and supply of prefabricated wooden houses, focusing on potential and obstacles to market development. The environmental part aimed to estimate CO2 emissions and embodied energy of wood products for the construction, to subsidize data for discussion on the impacts of increasing wood in the Brazilian construction. It was concluded, within the limits of this work, that the planted wood use could be implemented as a strategy for reduction of CO2 emissions in the civil construction sector in Brazil, because it is considered carbon neutral; on the other hand, native wood, being considered a carbon source, should not be used for this purpose. The decrease in the embodied energy of the sector, according to the business as usual, depends more on changes in the processes related to the masonry materials than wood. However, the implementation of the use of wood has some challenges, like the acceptance of the general public, whose concerns include the durability, maintenance and security of the wood. In addition, a strong correlation was found between the wooden houses decrease with GDP increase which may suggest that use of wood for housing is related to the population purchasing power. The price of materials may also have influenced this decline. The expansion of wood use depends, in addition to financial incentives and societal convincing, skilled labor qualification, technological development, reduction of bureaucracy, improvement in infrastructure for the flow of production, and public policies.

Повний текст джерелаCrane towers have a very relevant importance for building projects. With its inclusion in a project, this equipment facilitates the movement of construction materials, saving mainly time and work. However, the cost of its installation, general expenses, training, and others, can in several cases represent up to 7% of the total budget projects. For this reason, it is important to get the most value of this construction tool to speed up construction processes by fulfilling with the established schedule and avoiding delays that at the end turn into higher costs. The present study aims to propose a continuous improvement plan to increase the productive work of tower cranes based on an analysis of their work according to the Lean Construction methodology. The procedure consisted of collecting data through balance charts of three buildings whose stages of construction and execution of activities should be similar for these three projects. Then, we proceeded to identify possible causes of low productivity to be analyzed through a risk matrix and thus classify them according to the risk that each one would entail. Afterwards, those of medium and high criticality were selected with the final objective of proposing an improvement plan that would mitigate these problems. This proposal was implemented in one of the previously analyzed projects, finally obtaining positive results where the productive work had a minimum increase of 8%.

Повний текст джерелаVarious Artificial Intelligence methods have been developed to reproduce intelligent human behaviour. These methods allow to reproduce some human reasoning process using the available knowledge. Each method has its advantages, but also some drawbacks. Hybrid systems combine different approaches in order to take advantage of their respective strengths. These hybrid intelligent systems also present the ability to acquire new knowledge from different sources and so to improve their application performance. This thesis presents our research in the field of hybrid neuro-symbolic systems, and in particular the study of machine learning tools used for constructive knowledge acquisition. We are interested in the automatic acquisition of theoretical knowledge (rules) and empirical knowledge (examples). We present a new hybrid system we implemented: INSS - Incremental Neuro-Symbolic System. This system allows knowledge transfer from the symbolic module to the connectionist module (Artificial Neural Network - ANN), through symbolic rule compilation into an ANN. We can refine the initial ANN knowledge through neural learning using a set of examples. The incremental ANN learning method used, the Cascade-Correlation algorithm, allows us to change or to add new knowledge to the network. Then, the system can also extract modified (or new) symbolic rules from the ANN and validate them. INSS is a hybrid machine learning system that implements a constructive knowledge acquisition method. We conclude by showing the results we obtained with this system in different application domains: ANN artificial problems(The Monk's Problems), computer aided medical diagnosis (Toxic Comas), a cognitive modelling task (The Balance Scale Problem) and autonomous robot control. The results we obtained show the improved performance of INSS and its advantages over others hybrid neuro-symbolic systems
García, Katia Regina Punhagui. "Potencial de reducción de las emisiones de CO2 y de la energía incorporada en la construcción de viviendas en Brasil mediante el incremento del uso de la madera." Doctoral thesis, Universitat Politècnica de Catalunya, 2014. http://hdl.handle.net/10803/279369.
Повний текст джерелаEl presente trabajo busca analizar si el aumento del uso de la madera para la construcción de viviendas puede mitigar las emisiones de dióxido de carbono y disminuir la energía incorporada del sector de la construcción civil en Brasil. El énfasis está en la esfera ambiental, aunque también considera los ámbitos social y económico, que pueden influir en la concepción y eficacia de políticas públicas. Se ha estudiado el ámbito histórico para comprender el desarrollo del parque de viviendas de madera en los últimos cuarenta años y los posibles factores que pueden haber influido en su disminución porcentual dentro del parque total de vivienda brasileño. Se ha explorado el ámbito social para conocer la opinión pública sobre el uso de la madera para la construcción de viviendas, así como los puntos débiles y fuertes del material en el concepto general de la sociedad. En el dominio económico se ha intentado caracterizar el sector maderero y de suministro de viviendas prefabricadas de madera, con la pretensión de apuntar las potencialidades y obstáculos para el desarrollo del mercado. La parte ambiental ha buscado estimar las emisiones de C02 y energía incorporada de los productos de madera destinados a la construcción, con el fin proporcionar datos para discutir los impactos que tendría un aumento del uso de este material en la construcción civil brasileña. Se concluyó, dentro de los límites de este trabajo, que la madera plantada podría ser implementada como estrategia para disminuir las emisiones de C02 del sector de la construcción civil en Brasil, pues se considera neutra en carbono, mientras que la madera nativa, al considerarse fuente de carbono, no debería utilizarse con este objetivo. La disminución de la energía incorporada del sector, según los estándares constructivos actuales, depende más de cambios en los procesos relacionados con los materiales que componen la albañilería que de la madera. No obstante, la implementación del uso de la madera enfrenta algunos desafíos, como la aceptación del público en general, cuyas preocupaciones sobre la madera se centran en la durabilidad, el mantenimiento y la seguridad. Además, se ha encontrado una fuerte correlación entre la disminución de las casas de madera con el aumento del Producto Interior Bruto, lo que puede sugerir que el uso del material para viviendas tiene relación con el poder adquisitivo de la población. El precio de los materiales también puede haber influido en esta disminución. La expansión del uso de la madera dependerá, además de incentivos financieros y convencimiento de la sociedad, de la cualificación de mano de obra especializada, el desarrollo tecnológico, la desburocratización, la mejora de las infraestructuras para el transporte de productos y las políticas públicas.

Повний текст джерелаThe digital revolution is disrupting university practice and significantly impacting the spatial organization of higher education institutions. However, the spatial planning system of these territories of innovation and intense communication still continues to refer to master plans that do not allow changes in university practice to be integrated in real time and does not enable physical structures to evolve accordingly. Stemming from an urban planning and development perspective, this research questions the tools that currently govern the development of university space around the world, paying particular attention to attempts to update spatial management methods based on advances in the field of communication and information sciences and their application to the management of complex systems. The research thus aims to explore how an application of complexity theories to campus development would adapt the university’s planning and management system to the unpredictability of ongoing shifts, while allowing for the continuous adaptation of physical structures to these changes. After explaining the genesis and content of the main complexity theories in the scientific field, the research explores their application to urban planning, in particular through the planning model set up on the Eugene campus in Oregon in 1974 by architect Christopher Alexander. Understanding this unique model allows us to put into perspective the planning tools and methods in use at university sites in France, and in particular on the Bordeaux TPG campus. The research thus analyses the planning methods and tools used by the two university institutions in order to integrate (in real or delayed time) changes in university practice (learning and knowledge transmission methods, research), while adapting the physical structures of the campus

In construction, bridges are one of the most used ways to over come obstacles. To be more precious, bridges are used to connect transportaion channels like roads, railroads, canals, or over construction tools like channels, electric poles.Also bridges are used in order to over come natural obstacles like rivers, bays, valleys and so on or man made obstacles like highways,railroads, bridges are also the most important key to a transportation system because of the importance of bridges. The metal bridges competition benefit increasingly becoming more important. There are many construction methods for bridges, e.g., precast prestressing I-beam cantilever method, full-span precast launching method, advanced shoring method, incremental launching method, cast balanced cantilever method, precast segmental cantilever method, steel pipe outrigger trussing method, on-site shoring method, etc. However, this study probes solely into the precast segmental cantilever method for incremental launching method bridges with local shoring. Exploration of potential problems encountered in the process of designing and constructing of the bridges is performed. The measures for handling the problems and finally an autonomous checklist are created for builders’ references. The inner stress generated in various phases of the construction method might exceed the load-carrying capacity designed. Whether the attentions have been paid to the correct prestressing order is key to the success of the bridge construction. The method should carry out structural analysis along with the construction steps to confirm the stresses at any phrase are all in their allowable ranges. the scope of secondary allowance of inner stress. Study of the possible failure modes of the bridges after completion is also made herein and the likely failure load based upon the findings is proposed for designer’s reference.

"Improving FPGA designs with incremental logic resynthesis and shortcut-based routing architecture." Thesis, 2008. http://library.cuhk.edu.hk/record=b6074675.
Повний текст джерелаFPGA Technology Mapping is an important design automation problem which affects placement and routing dramatically. Depth-optimal technology mapping algorithms were proposed and produced quality mapping solution for delay minimization. However such algorithms have not yet considered to further reduce area consumption using the powerful logic transformation techniques.
On hardware side, we present a study on the effect of direct and fast routing hard-wires in FPGA routing architecture. Based on the routing pattern analyzed from real routing data, we proposed a so-called shortcut -based routing to handle short and localized routing requirements. Experimental results show that the shortcuts are well utilized and it allows a better average wirelength usage in the whole routing architecture.
On software side, we propose a versatile approach to combine logic transformation and technology mapping. In addition to a level-reduction scheme, we also present a method of reducing the number of LUTs used while keeping the depth optimality. Our approach is based on a greedy but effective heuristic to choose good alternative wires for transformation. Large number of experiments were conducted to analyze the effectiveness of the system. Our results show that our approach can effectively reduce at least 5% (up to 25%) of the area over initial mapping by various state-of-the-art FPGA technology mappers. Furthermore, we found that the delay performance can be improved by 5% when the area is reduced by our system.

Over the past few years, the RSEA company (author''s serving company) initiated a multi-discipline research team concentrating it efforts on the development of construction techniques of bridges so as to improve the company''s bridge constructing ability and to strengthen the company''s competing potentials in the construction market. The main goal of the teamwork would be to build up an independently managing system for the bridge construction and to reduce the overall construction cost as well. In this work, specific theories associated with stress analysis and construction practices during the entire construction duration for prestressed concrete bridges built using Incremental Launching Method (ILM) are reviewed. The contents of this thesis can be divided into two parts. The first part is aimed to study the construction characteristics of the ILM constructed bridges with emphases on the assessment of different employing devices and launching equipment demanded for various constructing methods and different site conditions. The second part of the study summarizes the programming efforts in preparing the input data for the ABI (Adapt Bridge Incremental) software. This bridge analysis software is currently used by RSEA in their design-analysis work of several ongoing bridge construction projects. Based on the developed forward and backward data treatment programs, better engineering decisions and more efficient scheduling process can be achieved. The well known Microsoft EXCEL spreadsheet was selected as the data treatment program module due to its simplicity and wide acceptance. The forward treatment program developed in this work, Abinp.xls, not only provides an efficient way in input preparation but also significantly reduces the editorial error caused during the input preparation process. When combining with the forward treatment program implemented with Fortran language, the developed package serves as a user-friendly checking tool with a quick evaluation process for the on-site structures. It is believed that the developed program package will provide a more appropriate decision-making environment to the engineers so as to save costs from the safety and the economy aspects. Finally, the C-CHO-BI No. 1 draining bridge of the project C334 of the Second Freeway (NanTou Segment) is used as an example to illustrate the application of the developed programs.

Повний текст джерелаObjectives Isotope ratio analyses of dentine collagen were used to characterize short-term changes in physiological status (both dietary status and biological stress) across the life course of children afforded special funerary treatment. Materials and Methods Temporal sequences of δ15N and δ13C isotope profiles for incrementally-forming dentine collagen were obtained from deciduous teeth of 86 children from four early-medieval English cemeteries. Thirty-one were interred in child-specific burial clusters, and the remainder alongside adults in other areas of the cemetery. Isotope profiles were categorized into four distinct patterns of dietary and health status between the final prenatal months and death. Results Isotope profiles from individuals from the burial clusters were significantly less likely to reflect weaning curves, suggesting distinctive breastfeeding and weaning experiences. This relationship was not simply a factor of differential age at death between cohorts. There was no association of burial location with stage of weaning at death, nor with isotopic evidence of physiological stress at the end of life. Discussion This study is the first to identify a relationship between the extent of breastfeeding and the provision of child-specific funerary rites. Limited breastfeeding may indicate the mother had died during or soon after birth, or that either mother or child was unable to feed due to illness. Children who were not breastfed will have experienced a significantly higher risk of malnutrition, undernutrition and infection. These sickly and perhaps motherless children received care to nourish them during early life, and were similarly provided with special treatment in death.

Smart phones have become very ubiquitous in recent years, and in-app advertising is a primary business model for mobile applications. Following this trend, researchers are interested in how to provide appropriate ads to target users. In this thesis, we particularly focus on considering and analyzing the role of apps in ad-clicking behavior. We believe that user preference will be directly reflected on the apps they use. To capture the hidden interests of their target customers, advertisers should identify the characteristics of apps. On the other hand, adaptive profiling has been proposed to match user profiles and campaign profiles. However, when applying this concept to mobile advertising, how to produce profiles from tremendous amounts of daily mobile data is a challenging issue. We explore the problem of producing mobile ad profiles from mobile user-generated data and incorporate the usage log of apps into ad profiling. We propose a novel 3-layer clustering framework to realize the tagging-based mobile ad profiling. Moreover, since new usage logs will be generated continually, an incremental mechanism is also designed to address the update issue and provide up-to-date clustering results.

Abstract Graduate Institute of Accounting National Taiwan University Title : The Effects of the One-Year Extension of the 50% Tax Rate Cut of the Land Value Increment Tax on Listed Construction Companies. Name : Chien, Yin Ying Advisor : Lin, Suming, Ph.D. Month/Year : June, 2004 Although there were heavy disputes over the extension of the 50% tax rate cut of the land value increment tax, the legislative Yuan finally passed the proposal to extend such tax privilege one more year till the end of January 2005. This study attempts to investigate whether the one-year extension of tax privilege would result in the positive cumulative abnormal volume (CAV) of the listed construction companies as well as the relation between CAV and the following five company characteristic variables: debt ratio, house built to sell/total assets ratio, land and construction in process/total assets ratio, market value/book value ratio, and stock’s closing prices on the event day. This study finds the following results. First, during the event dates (from 2003/12/29 to 2004/01/07), the average cumulative abnormal volume is 11.99%, which is significantly positive. Second, those listed construction companies with higher land and construction-in-process/total assets ratio had lower cumulative abnormal volume. Third, as the empirical evidence indicates, the debt ratio, house built to sell/total assets ratio, market value/book value ratio and stock’s closing prices were not related to the cumulative abnormal volume.

Financial integrity is the cornerstone of the country's economic sustainable development. In order to use the funds reasonably and effectively, the government will compose budget according to the possible annual revenues and annual expenditures, so as to prepare for the funding needs of the coming year. Tax revenue is the most important source of revenue for our government. Therefore, it's an important issue for the government to estimate the tax revenue effectively. There are various studies such as regression analysis and time series analysis have been used to predict tax revenue in the past. However, most of the research is based on the overall government's annual income or national taxes, and lack of local government and monthly income. In addition, with the development of information technology, the computing power of various hardware has been steadily increasing. The neural network has received attention once again, and the architecture that has been limited by hardware performance also can be realized. In the neural network that emerged in recent years, the recurrent neural network uses memory cells to transmit information, making significant progress in time-series related applications. And the improved version - long short-term memory recurrent neural networks is the main architecture be used. In his research, we uses the increase and decrease of land value increment tax in six counties such as Taipei City and New Taipei City as the forecast target. We test different neural network hyperparameters systematically to find the most suitable neural network architecture gradually, and forecast the tax increase and decrease and the tax level of the six cities respectively. According to empirical research, the long short-term memory recurrent neural network architecture adopted in this research has an average and best accuracy of 65% and 69% in terms of tax increase and decrease and tax level, respectively. The best result of accuracy rates for a single county are 76% and 93% respectively. Otherwise, in terms of the impact of data distribution on neural networks, after exploring the forecast results of various cities. We found that the distribution of data has no significant impact when predict tax increase and decrease. But the accuracy rate will increase when the distribution of tax revenue level is less balanced.
