Design concept development in transportation design

The paper presents results of a study about design concept development in transportation design. The main question of this study concerns mainly the existence and development of design concepts and its status in the design process furthermore it partially describes its content, manifestation and function. From the view of industrial psychology, the design concept is one of the most important stages in the design process, because its availability determines the success, regarding the design object. A design concept can be understood as the first solid and focused unit of knowledge in design processes with ill-defined problems. In the Design Process Planning, based on Action Regulation Theory, design concepts act as a compact guiding principle, including the anticipation of the artefact. Using this as a scientific basis a long term study with 25 students including cross section and longitudinal aspects were held from 2005 to 2008. Three concept types derived from the literature preceded the investigation, whereby the holistic experience-oriented one after Uhlmann (2006a) forms the beginning. This focus was confirmed within the investigation for the majority of the projects, yet one must assume that, functional (construction-oriented) or formal concepts successfully finds to application. Holistic concepts enable a more comprehensive and more balanced treatment within the design process. Within the work two general methods of generating design concepts: extracting and compiling were defined. Following the typical processes they can be assigned to different fields: transportation design (extracting) and industrial design (compiling). Furthermore three designer types and an open category could be identified. The three types “automobile”, “design” and “story” can be clearly and consistently assigned by the students. The research closes with a recommendation of a hybrid design concept processing using aspects of the two generating methods as well as instruments of different designer types.

Cross-Paced Representation Learning with Partial Curricula for Sketch-based Image Retrieval

In this paper we address the problem of learning robust cross-domain representations for sketch-based image retrieval (SBIR). While most SBIR approaches focus on extracting low- and mid-level descriptors for direct feature matching, recent works have shown the benefit of learning coupled feature representations to describe data from two related sources. However, cross-domain representation learning methods are typically cast into non-convex minimization problems that are difficult to optimize, leading to unsatisfactory performance. Inspired by self-paced learning, a learning methodology designed to overcome convergence issues related to local optima by exploiting the samples in a meaningful order (i.e. easy to hard), we introduce the cross-paced partial curriculum learning (CPPCL) framework. Compared with existing self-paced learning methods which only consider a single modality and cannot deal with prior knowledge, CPPCL is specifically designed to assess the learning pace by jointly handling data from dual sources and modality-specific prior information provided in the form of partial curricula. Additionally, thanks to the learned dictionaries, we demonstrate that the proposed CPPCL embeds robust coupled representations for SBIR. Our approach is extensively evaluated on four publicly available datasets (i.e. CUFS, Flickr15K, QueenMary SBIR and TU-Berlin Extension datasets), showing superior performance over competing SBIR methods

Heart Failure Monitoring System Based on Wearable and Information Technologies

In Europe, Cardiovascular Diseases (CVD) are the leading source of death, causing 45% of all deceases. Besides, Heart Failure, the paradigm of CVD, mainly affects people older than 65. In the current aging society, the European MyHeart Project was created, whose mission is to empower citizens to fight CVD by leading a preventive lifestyle and being able to be diagnosed at an early stage. This paper presents the development of a Heart Failure Management System, based on daily monitoring of Vital Body Signals, with wearable and mobile technologies, for the continuous assessment of this chronic disease. The System makes use of the latest technologies for monitoring heart condition, both with wearable garments (e.g. for measuring ECG and Respiration); and portable devices (such as Weight Scale and Blood Pressure Cuff) both with Bluetooth capabilitie

The modular structure of an ontology: Atomic decomposition

Extracting a subset of a given ontology that captures all the ontology’s knowledge about a specified set of terms is a well-understood task. This task can be based, for instance, on locality-based modules. However, a single module does not allow us to understand neither topicality, connectedness, structure, or superfluous parts of an ontology, nor agreement between actual and intended modeling. The strong logical properties of locality-based modules suggest that the family of all such modules of an ontology can support comprehension of the ontology as a whole. However, extracting that family is not feasible, since the number of localitybased modules of an ontology can be exponential w.r.t. its size. In this paper we report on a new approach that enables us to efficiently extract a polynomial representation of the family of all locality-based modules of an ontology. We also describe the fundamental algorithm to pursue this task, and report on experiments carried out and results obtained.

Contemporary painting based on the philosophical meaning of Surakarta Classical Batik / Adam Wahida and Endang Sri Handayani

This article is a result of a study to create contemporary paintings that have a local identity and character. The ideas of paintings creation are based on the philosophical meaning of Surakarta classical batiks, such as Sidoasih, Sidomukti and Sidoluhur which teach noble guidance about the life expectancy, existence, establishment, behavior and glory. Material related to forms and philosophical meanings is developed and linked to life today. The method of painting creation uses development research with steps that are namely: (1) information collecting, (2) development of the preliminary product, (3) preliminary product testing, (4) main product revision and (5) main field testing. The results of the study are contemporary paintings with a symbolic approach created using block, brushstroke and drip techniques on mixed media. The ideas behind paintings produced are representatives of the philosophical meanings of classical batik of Surakarta that are adapted to current life
