The time dilation formulas of both the specific relativity and the general relativity could be understood as children of a common expression that uses a factor dependent on the specific energy. Surprisingly when such factor is used to define the relativistic mass, the equation that arises is an extraordinary approximation of the mass and energy relation. An entangled mathematical perspective of both time and mass that opens up again the question of what their definition really is, and which are the factors that modify such variables.
A new formula has been developed that determines the passage of time. In the paper, this is particularized for cases of temporary dilation due to speed and gravity.
Additionally, using the previous equation, an interpretation of the nature of black holes, their formation, growth, and dimension can be developed.
Moreover, and based on all of the above, a different way of understanding mass and space is proposed. Which ultimately implies an alternative expression that relates mass and energy.

Using the previous equation, that serves as basis of the “Time Theory” proposed, an interpretation of the nature of black holes, their formation, growth, and dimension can be developed. Which ultimately leads to an alternative understanding of mass and energy.

The development of complex and dependable systems like autonomous vehicles relies increasingly on the use of systems modeling language (SysML). In fact, SysML has become a de facto standard for systems engineering. With model-driven engineering, a SysML model serves as a reference for the early defect detection of the system under design: the earlier the errors are detected, the less is the cost of handling the errors. Mutation testing is a fault-based technique that has recently seen its applications to SysML behavioral models (e.g., state machine diagrams). Specifically, a system's state-transition design can be fed to a model checker where mutants are automatically generated and then killed against the desired design specifications (e.g., safety properties). In this paper, we present a novel approach based on process mining to improve the effectiveness and efficiency of the SysML mutation testing based on model checking. In our approach, the mutation operators are applied directly to the state machine diagram. These mutants are then fed as traces into a process mining tool and checked according to the event logs. Our initial results indicates that the process mining approach kills more mutants faster than the model checking method.
Shortly after the comparative analysis of Codding et al. was published, I prepared a comment on the article that I submitted for publication. In response to feedback from the editors, I eventually revised the manuscript substantially. That revised version has now been published. In this paper, I share the original submission of the comment, which focuses on important considerations for future studies of risk-‐ sensitive foraging. Meanwhile, Codding and his colleagues have published a response to my comment. They exhibit some confusion about my position, which they describe as “paradoxical.” In a reply to their response, I have therefore added some clarifying remarks at the end of this paper
This paper presents a prime aspect of Augmented and Virtual Reality development in the field of healthcare. We explored several recent works and articles and a comparison between generic application development and immersive technology-based application is included. The paper talks about more practical approaches that can be taken to enhance the effectiveness of the application.
The resources (infrastructure) to complete this study are provided by the University of Cincinnati’s Center for Simulation and Virtual Environment Research (UCSIM). And several experiments and projects in the field of health care are used as a reference to make conclusions.
Ideation flexibility is the ability to shift between a designer’s preferred and non-preferred ways of generating solutions as required by the presented task. There are many tools that exist to support ideation; however, there is a lack of research defining how to facilitate ideation flexibility and how to support designers in this process through use of such tools. In this paper, we report on the development of a new tool, the "Incremental to Radical Heuristics" (I2Rh), which may provide inspiring prompts for ideation, ranging from more incremental to more radical examples. We tested the use of this I2Rh with a small set of industrial design and architecture students and aim to report on ways in which designers with varying cognitive styles perceive and apply these heuristics and further the impact of the heuristics on the students’ problem solving processes and ideation outcomes. Preliminary results demonstrate that more innovative students found the adaptive applications of the heuristics to trigger more novel solutions, whereas the more adaptive students found that the innovative applications to be more inspiring.
Ideation is critical as it allows designers to form many diverse ideas to choose from and eventually test and validate them (Sheppard, Macatangay et al. 2009). However, in many cases, designers find it difficult to come up with many diverse ideas as a result of fixation they experience on particular ideas (Crilly 2015). Being a flexible designer means being able to move from one solution to another, in order to produce the most promising solutions for the given context. In this movement, idea generation methods play a critical role as facilitators of this movement while pushing designers to think differently (Silk, Daly et al. 2014). The focus of the proposed work is ideation flexibility (Yilmaz, Daly et al. 2014), defined as the ability to ideate in both incremental and radical ways – or, more precisely, to ideate along a continuum of thinking between the two, depending on the needs of the problem. Building on the theoretical foundation of Kirton’s adaption-innovation theory (Kirton 1976), we defined the ideation success as a designer’s ability to move between his/her preferred and nonpreferred ways of generating ideas as required in the design brief. To specifically target ideation flexibility, we took an empirically-driven and validated ideation tool, Design Heuristics (Yilmaz, Seifert et al. 2016), and modified it based on the Kirton’s adaptiveinnovative theory. This revised set, called the "Incremental to Radical Heuristics" (I2Rh), illustrates heuristics’ application both incrementally and radically to the same example design problem. I2Rh is intended to help designers execute an ideation strategy based on prompts, examples, and directions to incorporate more incremental or more radical changes to their naturally preferred ways of generating ideas, through facilitating flexible thinking. Our goal in this paper was to investigate how designers with different cognitive styles perceive and apply these revised heuristics and their impact on the students’ ideation outcomes.
It is shown in present study that Rainflow method is unable to accurately estimate fatigue life ofcomponents under random loading, almost always. The inconsistencies between results of Rainflowmethod and hysteresis curve are also discussed. Alike the Peak counting method, it is shown that Shadowmethod doesn’t consider the possibility of deformation within individual cycles. Hence, Moshrefifar andAzamfar method is proposed as a novel technique having accurate results in different analytical condi-tions which are in good consistence with results obtained from hysteresis curves. Authors finally proposean algorithm as well as a C language program for this method.
Traditional craft has been relegated to the margins in modern culture, being perceived as out step with technological, economic and societal progress. However, emergent research is rediscovering the nature of craft and its potential for contributing to design practice in conjunction with developments in science and technology. Through the analyses of craft and sustainability, strong connections are revealed as well as some incompatibilities. The contribution of this paper is to a) map a systemic view of craft and b) establish a theoretical understanding of the relationship between craft and a holistic understanding of sustainability. Drawing on recent research that proposes three areas of leverage for sustainability, we argue that craft, as a system of making, knowing and being, has significant potential to contribute actively and tangibly to the transitional conditions, thereby serving as an agency for sustainable transformation.
Japan has become a super-aging society, with the number of older people (over the age of 65) at a historical high both in absolute numbers (33 million) and as a proportion of the total population (26.0%). Walking is known to be associated with positive psychological improvements such as in subjective sense of wellbeing, life satisfaction, and a sense of purpose in life, as well as improvements in physical and mental function, such as arm/leg muscle strength and standing balance. In this study, we focus on information about functions for assisting walking, comparing and contrasting the information provided by existing products that support walking with the goal of clarifying issues from an information-provision viewpoint. We conducted interviews with eight older people who go for walks on a daily basis, asking about their thoughts before, during, and after walking. From 110 total comments, we obtained 30 comments relating to the action of walking. Furthermore, we investigated the functions of 11 devices and 20 applications that support walking, and from 24 functions, we focused on 20 functions relating to the action of walking. By comparing and contrasting the twin perspectives of “information items” and “information content” with visualization levels identified in the field of management, we clarified issues relating to devices and applications for supporting walking among older users, from the viewpoint of information provision.
In the field of information technology, virtual reality and simulation learning have become huge trends, not only in gaming and entertainment, but also in academic fields such as medicine. In the past, medical training has always been costly in providing tools and resources for entry-level medical students to acquire proper training. Medical training conducted in a virtual environment has not only yielded higher success rates, but has also reduced resource costs overall. However, with no standardized guidelines for conducting certain training regimens and learning skills, there are still studies that show some medical training programs do not produce the best results. This research focuses on analyzing the usage of virtual reality in current medical training programs to design a medical, virtual reality, training program. This program will revolve around entry-level medical students who will be attending the University of Cincinnati’s College of Medicine. This research proposal will not only examine previous research on the utilization of virtual reality in various types of medical training, but also discuss the potential benefits of developing this training program at UC.
How do arts-based writing endeavors catalyze generative thinking and support research development in design students’ thesis endeavors? This paper offers reflections from an industrial design masters student, a graphic design masters student, and their arts education professor in a School of Design at a Research I institution. Informed by theoretical and historical contexts of the design discipline and perspectives from composition studies and fine arts practice, we explore the potential of arts-based writing as an evocative, speculative tool and a distinctive form of reflective practice for the development of graduate design research. We suggest that arts-based writing’s iterative process, dialogic engagement, and speculative approach to knowledge-construction provide critical, reflective structures for working through uncertainties and thus are uniquely responsive to the evolving epistemologies of the transdisciplinary university. Three focal questions guide this reflection: What is arts-based writing? What role does arts-based writing play in students’ design research endeavors? How can arts-based writing practices support the growth of speculative and pragmatic design research?
Having observed that many industrial design projects are started with the wrong approach, producing loss of resources, time, and professional relationships, this article presents a set of three tools that enables a clearer view of the Fuzzy Front-end (Vogel, Cagan). The first tool helps to understand the design order (Buchanan) of the product to be developed, and to place it in the utilitarian product universe (practical and economically biased), the transitional-wholistic product universe (practical, economic, and emotionally balanced), or the emotional product universe (viscerally and symbolically biased). The second identifies a product’s global purpose composed by its practical, economic, and emotional purposes, as well as the value factors they include (practical and indicative function, usability, practical or emotional cost-benefit, visceral appeal, and symbolic meaning). The third tool involves the type of project to be undertaken (vision, new development, major enhancement, or minor enhancement). Applicable to all disciplines of design, the three tools comprise the product identity footprint, which helps inform the selection of appropriate strategies to start a project the right way. It can increase the efficiency of the product development process by providing an agreed view that can be shared with all the development team, from the project sponsor to the engineering, marketing, planning, and creative departments.
This submission reports a design-driven integrated innovation on EV mobility, EV 3.0, as a collaboration between design research institution and a small BEV company in China. The on-going project provides a novel vision and design strategies of Battery Electric Vehicle (BEV) and mobility and has achieved a key technological performance on rapid charging of BEV. The current situation of BEV Industry and their recharging patterns show a big gap of new energy mobility. Key issues of BEV and mobility are defined by analysis of users’ need of mass market and a case study of a leading BEV. Usability of charging is identified as a bottleneck of BEV industry. Hence a new vision and scenario of rapid charging are defined, leading to respective design strategies and technological routines. With a long term investigation and iterative prototyping, an established prototype is developed and officially tested in the National Center of Supervision and Inspection on New Energy Motor Vehicle Products Quality in Shanghai. The test result indicates that the prototype has 431 km range in speed of 80km/h with only 15 minutes’ recharging, which provides a valid routine to break bottleneck of BEV industry .
Design processes are so complex that it is not easy to remember, reflect and record in detail after the actual processes are over. This paper proposes a notation to depict a design process as a whole while keeping its original complexity in terms of visual and structural aspects. The notion affords two types of structures to represent design processes, through activity units, a series of actions of the same kind, and design elements including ideas, prototypes and theories emerged, created, and applied during the design process. We use a design process of an actual design workshop as a case to derive the notation while using the online presentation tool “Prezi” as an interaction framework. We then investigated the depicted design process by re-experiencing the process as a first-person engagement using the designed notation. Prezi's animation mode allowed us designate a sequence along which viewers can experience the design process by zooming in some activity units and design elements, and its presentation mode allows us to look back the design process from the start to the end by following activity units arranged in the temporal order. Following the transitions among some design elements allows us to focus on essential objects in the design process. The depicted process illustrate that the two structures of activity units and design elements are not corresponding to but independent of each other.
Over the last two decades, constructive design research (CDR) — also known as Research through Design — has become an accepted mode of scholarly inquiry within the design research community. CDR is a broad term encompassing almost any kind of research that uses design action as a mode of inquiry. It has been described as having three distinct genres: lab, field, and showroom. The lab and field genres typically take a pragmatic stance, making things as a way of investigating what preferred futures might be. In contrast, research done following the showroom approach (more commonly known as critical design (CD), speculative design, or design fictions) offers a polemic and sometimes also a critique of the current state embodied in an artifact. Recently, we have observed a growing conflict within the design research community between pragmatic and critical researchers. To help reduce this conflict, we call for a divorce between CD and pragmatic CDR. We clarify how CDR and CD exist along a continuum. We conclude with suggestions for the design research community, about how each unique research approach can be used singly or in combination, and how they can push the boundaries of academic design research in new collaboration with different disciplines.
