This paper deals with the detailed conceptual design development of an autonomous vehicle, with the primary goal of transporting people with mobility problems or visual weakness, and thus avoid the risk of falls, tiredness, and fatigue; this aims to satisfy the needs of an increasing population with disabilities. An alternative solution is set for transfer based design methodology, which addresses each of the established requirements. The design stages established by Pahl & Beitz are described in detail, from the design proposal to functional prototype. The result of this work after evaluating the technical and financial analysis is a proposal of the functional design of the autonomous vehicle, which will be used in the main entrances of the Polytechnic University of Guanajuato (UPGTO). Regarding the autonomy of the vehicle, a vision system can be integrated if necessary as futre work, which will ensure its functionality and safety throughout its way; and thus be able to move through the main entrance towards the desired site.

A novel compliant transmission mechanism that doubles the frequency of a cyclic input is presented in this paper. The compliant cycle-doubler is a contact-aided compliant mechanism that uses intermittent contact between itself and a rigid surface. The conceptual design for the cycle-doubler was obtained using topology optimization in our earlier work. In this paper, a detailed design procedure is presented for developing the topology solution into a functional prototype. The conceptual design obtained from the topology solution did not account for the effects of large displacements, friction, and manufacturing-induced features such as fillet radii. Detailed nonlinear finite element analyses and experimental results from quasi-static tests on a macro-scale prototype are used in this paper to understand the influence of the above factors and to guide the design of the functional prototype. Although the conceptual design is based on the assumption of quasi-static operation, the modified design is shown to work well in a dynamic setting for low operating frequencies via finite element simulations. The cycle-doubler design is a monolithic elastic body that can be manufactured from a variety of materials and over a range of length scales. This makes the design scalable and thus adaptable to a wide range of operating frequencies. Explicit dynamic nonlinear finite element simulations are used to verify the functionality of the design at two different length scales: macro (device footprint of a square of 170mm side) at an input frequency of 7.8Hz; and meso (device footprint of a square of 3.78mm side) at an input frequency of 1kHz.

Mitsubishi Heavy Industries, Ltd. (MHI) has been carrying on development of a SMR for global strategic business and a conceptual design study of HTGR, namely MHR-50/100is having a high inherent safety and a high economical advantage for commercialization with supporting by Japan Atomic Energy Agency (JAEA). To begin with, a design philosophy of the MHR-50/100is had been set and the next phase, a conceptual design including plant dynamics analysis to investigate operational function and plant controllable performance had been carried out. It has been improved to establish higher safety level to meet the safety requirements after TEPCO’s Fukushima Daiichi Accident on March 11, 2011 in Japan. A market research and a financial analysis to review a feasibility of nuclear business have been studied. Consequently, it has concluded that the large market and the business potential will be prospected. We envisioned that it is effective for acceleration of MHR-50/100is utilization to show wider application of the nuclear energy in general industry as well as electricity generation. In the study cooperative with these users, we have studied on a practical applicability of MHR-50/100is in a typical general industry. A concept of the heat utilization plant consisting of the MHR-50/100is and hydrogen production plant has been developed; a safety concern has been evaluated. This paper reports a summary of a series of the conceptual design studies, and the various evaluation analyses in which we investigated a technical feasibility and a business potential of MHR-50/100is.

 The study was aimed to design the  landscape on the sides of Baghdad-Babel road and landscaping the aspects of this section of the road length of 1 km, which represents the main entrance of the province of Babel, which is the municipality of Alexandria to achieve the strategy of beautiful roads through the appropriate selection of types of vegetation and emphasis on local species and adapted to environment and soil, which is one of the main factors in the conservation of vegetation on the sides of the roads, as well as the preparation of a design proposal for a rest area on the right side of the section of the road under study to an area of ​​270,14.108 m2 is not intended for any future use, its currently used by drivers of heavy and medium vehicles and the regular vehicles and passengers while waiting at the entrance to the province of Babylon and provide an opportunity to reduce stress and fatigue on the driver and management of travel requirements and improve traffic safety by reducing traffic accident rates as a result of traffic density in this way.

Abstract The authors discuss, from quite different perspectives, some commonly held intuitions about design. In particular, Kota presents a functional design methodology and argues that distinctions between functions, constraints, and structures are essential to well organized design processes, which he sees as involving a hierarchical process from conceptual to routine design. Ward disagrees.
