Citizen science projects are based on gathering data from citizens. Citizen science projects start from understanding what type of data is needed and from whom. This can lead to creating a conceptual model for the project. Citizen science projects often use web interfaces and creating the interfaces require specific tools or programming knowledge. Having a method for creating the interface from a conceptual model would increase project development speed. This paper tackles the presented idea by using simple steps to create a web interface from an object-oriented conceptual model using XML transformation language XSLT. The model is transformed into a text-based representation using XSD that is then turned into an XML template. Finally, XSLT is used to generate a web interface by transforming the XML file. Results show that the process from object-oriented model to XML can be automated and the programming required for a working web interface is minimal but without other programming languages, the functionality is lacking. At the end of this article, some design suggestions are given to increase the functionalities while maintaining a low amount of programming.

The article is dedicated to development of an objectoriented model of an intelligence system based on case-based reasoning (CBR). An upgrade of the decision tree has been introduced to represent the situations hierarchy and related decisions in the knowledge base. The construction of the situations tree has been described. The problem of representing the situations tree in terms of classes and objects has been solved and the method of storage of the situations tree in the database has been defined. As a result, on the basis of the object-oriented paradigm the proposed approach allows creating domain-independent CBR systems that are shells for filling with case-oriented knowledge to solve specific problems.

Functional programming is a technique for expressing the constructions and constructs of computer software. This technique treats calculations similarly to the calculation functions in mathematics. Therefore concepts of semantic-states and changeable data are avoided. It may be defined as a declarative technique of programming meaning that programs are mainly expressions. An efficient programming style for systems is asynchronous programming which manages communications with system environment. Asynchronous programming is based on the idea of non-blocking execution of commands and keeping list of tasks in buffers for latter executions. The alternative style to asynchronous programming is to wait for the completion of long commands which leads to programs-execution problems. This paper introduces a robust framework for asynchronous operations on a functional object-oriented model for programming. Up to our knowledge, this is the first technique of its type. The presented model includes syntax for the language constructs and their (operational) semantics. The semantics is meant to serve as a formal background for the construction of theoretical analyses for the presented programming model. The paper presents also a programming example for the proposed model.

Automated operation and artificial intelligence technology have become essential for ensuring the safety, efficiency, and punctuality of railways, with applications such as ATO (Automatic Train Operation). In this study, the authors propose a method to efficiently simulate the kinematic characteristics of railroad vehicles depending on their speed zone. They utilized the function overloading function supported by a programming language and applied the fourth-order Lunge-Kutta method for dynamic simulation. By constructing an object model, the authors calculated vehicle characteristics and TPS and compared them with actual values, verifying that the developed model represents the real-life vehicle characteristics accurately. The study highlights potential improvements in automated driving and energy consumption optimization in the railway industry.

Thermal-hydraulic analysis of superconducting cables for energy applications with a novel open object-oriented software: OPENSC²

Super-conducting cables are an enabling technology for energy applications such as large magnetic-confinement nuclear fusion machine, and a promising key player in the power transmission of the next future, both in AC and DC conditions. While the thermal-hydraulic analysis of forced-flow superconducting cables for fusion application can only rely on commercial or proprietary numerical tools, such kind of tools for power transmission cables are not even available. Within the framework of Open Science, set as a priority by the European Commission in Horizon Europe, the novel software OPEN Super Conducting Cables (OPENSC2) has been developed to grant the entire research community the possibility to simulate thermal-hydraulic transients in forced-flow superconducting cables for energy applications. A Test-Driven Development has been adopted for the OPENSC2 within an object-oriented approach. Following the TDD approach, three test cases are considered of paramount interest for the OPENSC2 development, deriving the set of characteristics that the target object-oriented tool should comply with, and namely: 1) a heat slug propagation along an ITER-like 2-region cable-in-conduit conductor, with a thousand of mm-size low-critical-temperature superconducting (LTS) strands, cooled by supercritical helium (SHe);2) the heat diffusion across the cross section of a twisted-slotted-core cable-in-conduit conductor, with high-critical-temperature (HTS) superconducting tapes, for fusion application, cooled by SHe and 3) the nominal operation of a single-phase HTS High-voltage, Direct Current power cable, with a 2-cryostat configuration and 2 different fluids adopted as primary coolant and thermal shield. In the object-oriented OPENSC(2 )the class "conductor " is defined, where each Conductor object (CO) is the combination of different lower-level objects (both fluid and solid components) instantiated by the class. The choice of each component drives the automatic selection of the appro

The present paper is devoted to the creation of a model and algorithm of an artificial immune system (AIS). The proposed model and algorithm are considered for realization of the problems single symbols recognition, symbolic regression, managing autonomous systems (robot). In the description of the proposed artificial immune system model and algorithm research methodology from the natural immune system is preserved. The adopted concept of B-cells are responsible for producing antibodies, a special class of complex proteins on the surface of B-lymphocytes, capable of binding to certain types of molecules (antigens) is used. The full set of antigenic receptors of all B-cells is a plurality of antibodies that can be produced by the organism. The developed program complex allows to solve all three problems: single symbols recognition, symbolic regression, managing autonomous systems (robot).

作者： Elias Yilma Addis Ababa University

学位级别：硕士

In this research, cost optimization of reinforced concrete plane and space frames using genetic algorithms is presented. Previous research endeavors have used highly simpli? ed continuous and discrete optimization models, while ignoring constructibility. Addition- ally, the optimization of 3D frames was done without due consideration to shear, torsional e? ects and sizing constraints. This paper constructs an optimization model with these points in mind. An integrated software architecture has been developed to implement the method, and benchmark examples were used to compare its feasibility and e? ciency with the traditional assume-check design method as well as other heuristic methods. De- sign check procedures were based on Eurocode-2(2004). Performance and computational complexity of the algorithm is developed along with a thorough study assessing the e? ect of genetic parameters such as mutation and crossover on the optimization process. The method developed proves to be superior as compared to the traditional design paradigm and heuristic methods.

A New Approach for N-ary Relationships in object Databases 33

In an object-oriented or object-relational database, an n-ary relationship among objects is normally represented in a relation that is separated from other properties of objects at the logical level. In order to use such a database, the user needs to know the structure of the database, especially what kind of relations and classes there are, how they are organized and related in order to manipulate and query object data. To make the logical level closer to the conceptual level so that the database is easier to use, we propose a novel approach that allows the user to represent n-ary relationships among objects in their class definitions so that the user can directly manipulate and query objects based on the class definitions, rather than explicitly join relations at the logical level. Based on the class definitions, the system can automatically generate the modified class/object relation definitions and the corresponding regular relation definition for the n-ary relationship at the physical level to reduce redundancy and convert data manipulation and query statements based at the logical level to ones at the physical level.

In WSNs, hundreds of sensors collect data from the environment but these sensors have limited energy. Therefore, energy consumption is a very challenging issue in the design of WSNs. Sometimes, sensors fail as they got affected by the pressure or temperature. Such failure can lead to misleading measurements which in turn are waste of energy. As a result, data fusion is needed to overcome such confusion where it assures data's efficiency and eliminates data's redundancy. This paper provides an analysis of the state-of-the-art data fusion models along with their architectures. It also presents a comparison between these models to highlight the main objectives of each. In addition, it analyzes the advantages and the limitation of these models.

In this paper we present a new classification of object-oriented metrics, in order to facilitate software evaluation. This classification is based on standardized model "ISO 9126" and focuses on design and quality properties. The crux of this work is to make the relationship between sub-characteristics of ISO model and properties of object-oriented design and quality. Thus our purpose is to find a way to evaluate software without neglecting the properties of the object-oriented design such as: abstraction, inheritance, encapsulation etc.
