This report focuses on solving the cargo transportation problem for Express Air, an air express company operating among three airports. The objective is to minimize costs while meeting the daily demand for cargo transportation between each origin-destination airport. A minimum cost optimization model is employed to find the optimal schedule. Sensibility checks are performed, and the results are analyzed, including various scenarios using the developed models. The mathematical model includes variables representing cargo amounts, repositioning aircraft, staying aircraft, and cargo left on the ground. The objective function aims to minimize the total cost of cargo left on the ground and repositioning aircraft. Constraints ensure the balance of aircraft and cargo flows and account for demand and cargo left from previous days. The optimal solution yields a total cost of 17,925, with repositioning aircraft accounting for 84.38% of the cost. Increasing the fleet size reduces costs, and the model can be applied to supply chain systems and on-line shopping logistics.

In the traditional sense, "organic architecture" can be classified as a member of the modernist architectonic array, represented by a group of American architects including Sullivan and Wright. This movement believes that architectural form and composition can be inspired by nature, starting from the inner elements rather than simply imitating biological nature. The meaning of "organic architecture" emphasizes more on drawing living forms from nature and forming a concept that can penetrate every detail of the building, according to the unique functions and conditions of the space, making the building an interdependent and inseparable entity. This article provides a brief overview of the background of Wright's representative work, the Fallingwater house, and analyzes the interior space design of the Fal-lingwater house from three aspects: spatial organization, interface design, and furniture layout. It concludes and summarizes the characteristics of the Falling-water house, hoping to provide reference examples for contemporary architectural design and urban environmental art design.

In engineering scientific communication, technical language serves as the carrier of information. Technical languages are linguistic tools for communication in specific field, enabling mutual understanding. This study examines four module handbooks of the Bachelor's program in Mechanical Engineering in the German-Chinese double degree program. The focus is on the compulsory technical modules, which contain the important specialized courses. Firstly, the study analyzes competence descriptions of these courses in the four module handbooks, from which communication procedures can be derived. Based on this analysis, specific communication procedures and typical linguistic resources for successful technical communication are identified. Statistics and analysis demonstrate that students need to be proficient in various areas of technical language such as "explaining", "describing", "evaluating" and "analyzing", as they are elementary for technical communication in the mechanical engineering course. Based on these findings, specialized language courses should be specifically designed to impart the necessary communicative skills to students in relation to these communication procedures. It is important to develop both oral and written communication skills in order to explain complex matters, analyze systems, weigh advantages and disadvantages, and make evaluations.

Luoyang city is located in the west of Henan Province. The climate of Luoyang city is windy and arid in spring, hot and rainy in summer, sunny and sunny in autumn, and dry and cold in winter with little rain and snow. There are four distinct seasons throughout the year, and the distribution of heat and precipitation has significant seasonal characteristics over time. In order to respond to the national sponge city construction call, ensure urban ecological security, relieve the pressure of urban waterlogging, highlight the regional cultural characteristics, it is proposed to build a cultural sponge city with "four rivers running through the capital and city water merging". By comprehensively analyzing water ecology, biological habitat, food production, cultural recreation and other factors, the multi-level ecological security pattern of the city, urban planning area and urban center should be established, and the sponge system of mountains, rivers, forests, fields and lakes should be constructed and improved to ensure system security.

The orderly progress of the technology and management of HVAC engineering can provide relevant conditions for the building in a sense, and form a set of effective measures to maximize the use value of energy. HVAC construction technology can prevent the excessive consumption of energy, improve the efficiency of use, so that the building HVAC project can be better implemented, HVAC construction as an important core of civil construction projects, related to the final construction quality of the project. In the construction of HVAC engineering, the staff should master the relevant construction technology, do a good job in construction management, provide support for the construction of civil buildings, and ensure the quality of HVAC engineering projects. The final role played by HVAC engineering can not be ignored, it will not only affect the specific application of building facilities, but also bring certain damage to people's living environment. Therefore, in the construction stage, it is necessary to effectively use HVAC engineering construction technology, and under strict management, so that the construction quality can meet the corresponding standards and requirements. This paper focuses on civil building HVAC engineering, aiming at improving the level of civil engineering construction in our country and ensuring people's quality of life.
