Semantic Definition

The purpose of the article is to consider the concept and determine its components, in the development and analysis of conceptual art in modern design. Methodology. The following methods are used: analysis, synthesis, as well as semiotic, hermeneutic, psychoanalytic. The scientific novelty of the work lies in the study of conceptual art on the examples of hairstyle design, hairdressing collections, and an attempt to comprehend the underlying contexts and meanings in the process of interpretation. Conclusions. Given the fact that modern design as a polymorphic entity with a dominant innovative component actualizes the activities of the new generation and acquires the features of intellectual comprehension of visual information, it can be argued that conceptual art is a priority in this direction. The concept as the initial concept of the conceptual is defined as a multilevel formation of content, the semantic meaning of the sign, which requires a process of interpretation. Through J. Dili's study of the theory of sign systems, the interpretation of the concept in the system of traditions, rituals, customs, which is perceived differently by different people due to belonging to different cultures, societies, etc., becomes clear. It is proved that the creation of the concept is based on processes based on individual practice, personal associations, and the main types of metaphorical and allegorical thinking that arise from the experience of not only cognitive but also substantive activity. The study of conceptual art on examples of hairstyle design, hairdressing collections shows the peculiarity of such works of art: they are not always functional and are not always defined as a utilitarian object, but the use of unusual color, shape, progression, silhouette lines, the fullness of space and volume with signs and symbols, require a multilevel semantic definition in the process of interpretation through intellectual comprehension of the inherent contexts and meanings. Keywords: conceptual art, concept, design, hairstyle.

Kinematic Performance

Purpose Removing the bone flap is a compulsory step in open skull surgeries and is very cumbersome and time-consuming. Exerting large forces during the milling and cutting of the skull renders the surgeon exhausted and consequently increases probable errors in further task of manipulating the sensitive brain tissue. This paper aims to present the development of a robotic system capable of perforating and cutting the required bone flap without restraining the surgeon. Design/methodology/approach For the purpose of optimization, the target workspace is estimated by 3D modeling of the sample skull and bone flaps of targeted surgeries. The optimization considers kinematic performance matrices and the extracted workspace requirements by assigning scores to each possible design and finally selects the design with highest score. Findings The design utilizes a parallel remote center of motion mechanism. Coordinating the remote center of motion (RCM) of the mechanism with the center of a sphere which circumscribes the skull, the milling tool is always nearly perpendicular to the skull bone. The paper presents the concept design, optimization criteria and finally the optimal design of the robot and the fabricated prototype. Tests indicate that the prototype is able to sweep the target workspace and to exert the required forces for bone milling. Originality value The workspace requirements of the craniotomy/craniectomy surgeries are investigated and converted into one quantitative target workspace. An optimized design for a surgical robot is developed which satisfies the workspace requirements of the targeted surgeries.

Verification Methodology

This paper presents a new energy harvesting (EH) concept design, referred to as EH skin structure. A generic design and experimental verification methodology will be proposed to demonstrate the feasibility of the EH skin for practical applications. In the past, EH researches have primarily focused on designing a device-level energy harvester, such as a cantilever-type EH device. However, such a device-level energy harvester has several drawbacks: (i) need of an extra space for proof masses and fixture, (ii) significant energy loss due to the fixture, and (iii) need of a casing for EH device protection against environmental harms. While this new EH concept design could overcome the drawbacks above, there is no design methodology for EH skin. This paper proposes design and experimental verification methodology for EH skin structure. The design methodology comprises three tasks: (i) construction of a valid computational model, (ii) design optimization of EH skin, and (iii) experimental verification. An outdoor condensing unit of which a fan produces harmonic vibration is chosen for a case study because similar configuration of vibration can be found in many engineered systems (e.g., airplane wing, AC unit). The proposed design methodology determined an optimal EH skin configuration (sizes, locations, etc.) on the vibrating structure. The EH skin was carefully prototyped to demonstrate that it can generate power up to 3.7mW, which is sustainable for operating wireless sensor units for structural health monitoring or building automation.

Panel Design

Novel design methodology with inclusion of reliability and robustness-based design criteria is presented. Robustness is defined as the insensitivity of a design attribute to uncontrollable design parameters. The developed design procedure for the concept design phase is divided into two basic, coordinated tasks: (1) multi-criteria topology/geometry optimization of the ship structural model; (2) scantlings / material multi-criteria optimization of structural panels. Reliability criteria and robustness of design attributes are applied as relative measures of quality, besides standard design attributes such as costs and weight. They are used in generation of Pareto-optimal design variants. Reliability attributes used for the panel design are compared with respect to fidelity and computational efficiency. A novel method for fast reliability calculations is presented using dimension reduction method (DRM) as implemented into FASTREL software. The method is verified with respect to accuracy and speed on the box girder design and panel design with CalREL methods (MC, FORM). The design procedure steps are executed in the predefined sequence of design sub-problems, using the fast and balanced collection of analysis and synthesis modules/methods of the MAESTRO/OCTOPUS design system. They are as follows: • Probabilistic determination of design loads; • Calculation of the structural serviceability and ultimate strength criteria on the panel (macro-element) level; • Calculation of the cross section ultimate longitudinal strength criterion; • Calculation of reliability and robustness measures on the panel level (safety) and on the global level. Other design attributes (initial cost, structural weight, etc.) are also determined; • Generation of the Pareto frontier for the selected test structure based upon the cost–safety design paradigm; • Generation of insight into the multilevel optimization process with graphic presentation of designs in design and attribute spaces. Practical application of the developed concept design methodology and of the design environment to the structural design of modern multi-deck ship elements (panels) is presented for verification/validation of accuracy and speed of FASTREL module.

Abstract This paper presents the analysis of the effect of differential signal coupler positioning accuracy on its high frequency performance parameters for contact-less high speed chip-to-chip data transmission on PCB application. Our considerations are continuation of the previous works on differential signal coupler concept, design methodology and analysis for high speed data transmission monitoring. The theoretical analysis of possible coupler positioning innaccuracies is extended for representative design cases by simulations carried out using EM simulator. The results reported here confirm that the concept of contactless monitoring of high speed chip-to-chip data transmission in a pair of coupled microstrip lines is of practically usefulness without applying the expensive and precise positioning system
