Investigation of Floating Transportation Equipment for the Offshore Wind Power

This paper presents a floating transportation equipment (FTE) for the negative pressure suction bucket foundation (NPSBF) of offshore wind turbines, and the basic design and main transportation means are introduced. The hydrodynamic characteristics of integrated FTE-NPSBF structure are comprehensively studied. The ability of FTE as a transportation aid to provide stability for the NPSBF is verified, and the vibration reduction measures under the condition of wave resonance during the floating transportation process are given.

Modular E-Collar for Animal Telemetry: An Animal-Centered Design Proposal

Animal telemetry is a subject of great potential and scientific interest, but it shows design-dependent problems related to price, flexibility and customization, autonomy, integration of elements, and structural design. The objective of this paper is to provide solutions, from the application of design, to cover the niches that we discovered by reviewing the scientific literature and studying the market. The design process followed to achieve the objective involved a development based on methodologies and basic design approaches focused on the human experience and also that of the animal. We present a modular collar that distributes electronic components in several compartments, connected, and powered by batteries that are wirelessly recharged. Its manufacture is based on 3D printing, something that facilitates immediacy in adaptation and economic affordability. The modularity presented by the proposal allows for adapting the size of the modules to the components they house as well as selecting which specific modules are needed in a project. The homogeneous weight distribution is transferred to the comfort of the animal and allows for a better integration of the elements of the collar. This device substantially improves the current offer of telemetry devices for farming animals, thanks to an animal-centered design process.

Dialogical Structure Experience in Basic Design Studio at Online Education

In this study, the structure of the basic design studio that started with face-to-face education and had to end with online education due to the COVID-19 pandemic, which was set over Bakhtin's dialogic concept, is discussed. The three main components of the basic design studio; studio space, studio process and studio content and the combination of these components have changed in the transition from face-to-face education to online education. With these changes, dialogic relations are defined in the basic design studio's setup that extends from the face-to-face to the online education, and a structure that is shaped not as a sharp transition but as a flow has been developed. The basic design studio structure, which is shaped by the concept of dialogue, is presented as an approach proposal for online education, which is still ongoing and is expected to continue.

The Development of Frequency Tripler Based on Six-Anode Schottky Varactors

The development of a millimeter-wave unbalanced frequency tripler based on the nonlinear characteristics of planar Schottky varactors is presented. The entire module is designed by hybrid integration. A frequency multiplier circuit model was established to reflect the influence of diode parameters and the impedance matching on the multiplier in different frequency bands. The effect of junction imbalance on the output power of the frequency multiplier was investigated and the multiplier was improved based on the basic design. The addition of a cut microstrip stub in the improved diode unit reduced the impact of a power imbalance on frequency multiplier performance. The characteristics of the multiplier circuit were analyzed by the full-wave electromagnetic simulation of the three-dimensional structure and the harmonic balance simulation of the circuit. Test results showed that the peak output power of the improved frequency tripler was 12.6 mW at 277 GHz with an input power of 200 mW, an effective 12% improvement over the basic design.

Definition of a Basic Design for Conversion of an Offshore Fixed Platform on a Depleted Reservoir Into a Sustainable Plant

In the framework of energy transition, a focus is given to the study of the conversion of offshore Oil&Gas platforms at the end of their life due to depletion of the reservoirs on which they operate. Their modular and versatile structure allows the implementation of new processes and innovative sustainable technologies for reducing the environmental impact of a complete decommissioning, especially on the subsea ecosystem that has grown around the jacket, and for guaranteeing costsaving solutions. Among different conversion options, this paper focuses on the installation on the platform of a system for the production of photovoltaic (PV) energy to be used for seawater desalination and its delivery to other platforms operating in the same area. The project focuses on the definition of technical characteristics of the basic design, on the investigation of the technical feasibility of the conversion process, on qualitative safety and environmental impact studies. Moreover, the old platform equipment to be decommissioned (ie. the equipment necessary for hydrocarbons treatment) are identified and the installation of new equipment is optimized, eg. the number of PV panels and, therefore, the installed power are maximized. At the same time, decommissioning costs and impacts can be minimized. The basic design is completed with a preliminary structural verification to guarantee that critical situations do not rise, with an indication on the main maintenance activities for the preservation of plant good efficiency and with safety and environmental preliminary analyses for the identification of potential criticalities to be managed at different design levels.

Violation On the Basic Design of Al-Baghdadi City

The sustainable increasing in population coincided with continuous, constructional expansion of cites. It was the beginning of appearing the unlawful seizing of many areas in second world cities and the Iraqi cities in particular. thus it was very difficult for the mentioned cities to stand in front of these problems Al-Baghdadi city is also with in those cities that suffers from the illegal takings of many lands. The study aims to look over these unlawful misappropriating and to find out the reasons which stand behind this case and its locative distribution. The searcher depends on fielding study in checking these problem, through looking for many illegal taking which are not registered in Al-Baghdadi municipal. This study consists of three chapters, the first one is to know the meaning of misappropriating and its causes. The second chapter deals with the qualitative and locative circulation of these illegal behaviors and its affection on the constructional shape of the cites. While the third chapter considers the negative effects of this problem on the towns. This study gives many maps show these unlawful seizing in all districts in addition it gives the final conclusions and recommendation for this problem. Hopefully this study might be approved by all officials and members of governmental people. The study revealed that the abuses appeared clearly after 2007 due to the lack of security, the absence of the law and the difficulty of implementing it with the weakness of the regulatory bodies and the flexibility of some laws that gave the transgressor the right to own property as a reality that led to the exacerbation of the situation of abuses on the water, electricity, health and education services, as well as the abuses on land and streets and green areas.
