Research on the optimum path Taking the hospital delivery robot as an example

Medical delivery robot refers to the delivery robot used in the medical field. Compared with ordinary delivery robots, the medical delivery robot needs to work in an environment with many people, which means that it needs to deal with many random obstacles at any time. This article will discuss automatically avoiding obstacles, and formulate and compare algorithms to analyze the advantages and disadvantages of automatic road exploration algorithms of different algorithms. In order to accomplish this goal, this paper will use Matlab as the main development tool and use the A-star algorithm and the Euclid algorithm as the main heuristics in the main mathematical model of the program. This program needs to be able to complete the obstacle avoidance task in a map with random size, random position, random shape, and random number of obstacles, and be able to reach the end point from the starting point. In addition, this paper will also discuss the efficiency of the A-star algorithm and the Dijkstra algorithm in obstacle avoidance and route planning, and demonstrate why the A-star algorithm is more efficient by taking time and congestion indicators.

Design of Quantitative Trading System Based on Data Mining Method under Software and High-Performance Computing

The size of funds managed by all hedge funds in the world has exceeded 2.7 trillion US dollars. The funds of various funds and asset management products managed by quantitative investment account for about 30% of the total global trading volume, and in various large stock exchanges around the world, various quantitative investment methods contribute nearly 50% volume of transactions. The construction of a quantitative trading strategy requires first statistical analysis of the information in the securities and futures market and then backtesting the quantitative model with historical data. In view of the practical application of quantitative trading, this study designs a quantitative trading system based on the data mining method. The main development tool used is the numerical computing software MATLAB, and four cores are designed: quantitative stock selection, strategy backtesting, time-series analysis, and portfolio management. The system supports modules for simple trading decisions. It abandons the traditional method of predicting the absolute value of the future price of stock index futures and adopts a new method of predicting the future price trend of stock index futures. This method avoids the huge impact of the accuracy of the absolute value of the prediction on the final investment in the traditional method and also reduces the high dependence of investors on the accuracy of the absolute value. This study also introduces the support-vector machine algorithm in data mining and the quantitative trading system model in data mining. The accuracy of investment transactions in the experiment is also simulated by using the support-vector machine.

It uses the software’s advanced lighting system, particle system, and algorithms such as edge detection and screen post effects to establish the main frame of the system. It utilizes C # language for programming, thus enriching the functions of the system. On testing, the virtual interactive teaching system realized by the above method exhibits high interactivity, fun, and practicability.

Characteristics of private equity return: evidence from Brazil

Private equity (PE) stands out significantly in the world as one of the main development tools of the capital market in emerging economies and alternative sources of finance for companies. Particularly, the increase in fund value and continuous returns are objects of intense study in Brazil. The paper aims to find determinants to Brazilian private equity returns, regarding three relevant variables funds characteristics and GDP to a macroeconomic view. A sample of 1,112 PE funds registered at the Brazilian Securities and Exchange Commission (CVM) was used and analyzed by three main variables: period of establishment, equity size, and exclusivity as possible determinants of funds’ performance using multiple regression model and fourth variable GDP is applied as a descriptive variable. The results indicate that older funds had a return premium of 1.5% monthly over young funds, smaller funds had a return premium of 1.4% over larger funds, and exclusivity does not influence the funds’ performance. Thus, the paper provides a basis for the relevant factors that an investor should verify in Brazil’s private equity fund before allocating the resources.

Desertification in Iraq and how to Combatit

Iraq faces many environmental challenges as a result of its geographical location within arid and semi-arid regions, as well as the economic, political and security conditions it faced. Desertification comes at the forefront of these challenges as it is considered one of the dangerous environmental manifestations because of its direct impact on food security and the impact on human health, which is the goal and main tool for development. This problem has been exacerbated during the last two decades due to several reasons, the most important of which are climate change, low rainfall rates, misuse of natural pastures, overgrazing and urban sprawl at the expense of agricultural lands in addition to unsustainable farming methods and wrong practices in irrigation operations and the increase in land areas affected by salinity and the significant deterioration in vegetation and those Covered by Moving sand dunes as a result of land degradation and erosion. In addition to the phenomenon of drying marshes, as they dried more than more than 90% of its area, and the research dealt with dividing the land of Iraq according to its production capacity into eight comprehensive sections for eight varieties.

In the further research, the VR Chinese Idioms educational games for the TCFL can be better gradually based on this research.

Social Housing in Urban Regeneration. Regeneration Heritage Existing Building: Methods and Strategies

The theme of urban regeneration has played a strategic role during the last two decades in European and national urban building policies. Current addresses, also defined in Leipzig Charter on Sustainable European Cities in 2007, indentify the necessity to invest in requalification of degraded residential assets and not in new developments, individuating in urban regeneration the main tool for development of contemporary city. Public neighborhoods have developed, historically, a wide set of common problems. They are not only due to wrong planning but also to the concept of “housing for masses”. The original ambition of modern settlment, developed from GermanSiedlung, was to be an autonomous part, on the point of view of morphology, in urban expansion. Joined by new developments, a lot of neighborhoods became benchmarks for suburban areas and now we can define themas “new urban centralities”. So theirrole in urbandynamics has changed and they can be individuate dasprecious reserves of public spaces and potential incubators for regeneration of larger areas. Analyzing some Italian and European case studies, themostinnovative relate to the densification of open spaces, inserting new services in a general redesign of green areas; concentration of built surfaces, in order to reduce land consumption and introduction of different residential types in order to improve mischbebauung. The reasons for an active recovery are motivated by the criteria of environmental sustainability and saving land, have relaunched compact projects with medium to highdensity.

Quest for a better operation system in education: Privatization and teacher educationalization or voucherilization glimpsing from consumer and product perspectives

Inevitably, education is considered as the main tool for development. Regardless of nationality, race, age and culture, everyone in this contemporary world believes that education is the commonest medicine that cures every disease hindering the development of a nation. Keeping this view, countries put endless efforts in the development of education. Major phenomena for the development process of education include: privatization, teacher education, design of modern and well-timed course and curricula and establishment of infrastructure and logistics. For the allocation of national budget, most of the states provide the highest preference to education. Despite these efforts, many countries fail to achieve the target that is especially aimed for their national development through education. Why is this happening, since the purpose of education is to ensure national development? Encompassing of many research findings sums up that education is not playing the role according to its purpose. Thus, many prescriptions have been provided through researches with an ideology of ``Education as Right'' to solve the problems. All these suggestions are still unsuccessful to make the education system desired functional. The conducted research for this paper has to understand what would be the difference if students do not consider education as their rights, but do judge it as their assets and property. Results assert that this attitude would be able to change the psychological setup of poor students developing an ownership attitude toward education. This would irrevocably help to achieve the national goal of education. However, a new paradigm called voucherilization would be the key for the change of psychological and mental current setup of the underprivileged students.

Active participation of integrated development environments in the teaching of object-oriented programming

With the strong link between programming and the underlying technology, the incorporation of computer technology into the teaching of a programming language course should be a natural progression. However, the abstract nature of programming can make such integration a difficult prospect to achieve. As a result, the main development tool, the Integrated Development Environment, generally takes a passive role during the learning process. These software environments play a pivotal role in the development process and so should perform a more active role in the overall academic process. This paper describes the pronounced D-Chk system, which is an integrated development environment for the Java language. This system allows tighter integration between the theory and the practical aspects by incorporating several user interface and functionality enhancements.
