Using vision systems with SCARA robotic manipulators is beneficial in many industrial applications specially in automated object picking and placing tasks. In this paper, the equations of forward and inverse kinematics of a SCARA manipulator are derived using D-H parameters convention. The mechanical structure, as well as the electrical, electronic and pneumatic components of the manipulator were...
In order to improve the elïïciency of apple's grading and ensure the scientilïcity and objectivity of grading, this paper presents a three-stage grading system, namely weighing grading, color grading and shape grading. Hardware design uses high-performance S3C2440 embedded controller, DSP controller, single-chip micro-processor controller, pressure load sensor, color recognition sensor, graphic recognition...
In this study, spatial syntax analysis was applied to quantitatively investigate the spatial morphology evolution of the Xiamen port area. The map images of five periods including incubation, forming, expansion, steady and transformation periods were analyzed. The results showed that both global and local integration degrees decreased from incubation to steady periods. The integration core of the...
The paper is devoted to modeling of single-layer garments as developable median surfaces, modeled in the form of a thin supple shell. The products are modeled in Maple 9.5 and Embarcadero RAD Studio. The modelling of conical skirts considering seams is performed to demonstrate the space form of garments in the gravity field of elastic materials. Also the product aeroman is modelled which brings the...
This paper deals with the design, manufacture and application of NC machine for cutting 2D intricate path of plane styrofoam. The cutter uses nickel wire heated by DC electric current. The X and Y axis is moved using open loop controlled stepper motor. The path that is cut is first was taken from picture, than changed the captured picture into line graph, and then programming the machine to follow...
This paper proposes a framework for an Agent Auto-Generation System (AAGS) which gets information from sensor devices and improvises a conversational agent from arbitrary things. AAGS has agent-types to prepare a perception for an improvised agent according to the shape of the agentization targets. It also has virtual-input, which generates knowledge representation related to information extracted...
One of the major diseases affecting the global population, depression has a strong emotional impact on its sufferers. In this design study, "Talis" is presented as a wearable device which uses emotion recognition as an interface between patient and machine to support psychotherapeutic treatment. We combine two therapy methods, "Cognitive Behavioral Therapy" and "Well-Being...
It is assumed that Japanese can analogize the meaning of original text if they read the original text according to the commonality of written expressions, such as the commonality of Kanji and Chinese characters in case of Chinese-Japanese translations. In this study, participants rewrote translated sentences while viewing simultaneously the original sentences written in Chinese and the translated...
This research aims to study the neural influence of conflict between brand and product performance on consumer decision. In the experiment, stimuli of products with brand and performance information were displayed randomly. 22 subjects need to decide whether to buy, while the event-related potentials (ERPs) were recorded. The stimuli were divided into four conditions based on the consistency of brand...
Good results have been obtained for face alignment in a single image. This is beneficial from use of auxiliary models or prior information. Compared with a single face image, there is much information available in multiple face images of a person. Rigid joint alignment will use the information as a whole. The paper mainly contain two works, i.e. constructing rigid joint alignment of multiple face...
Learning about herb is important for daily medical treatment. People should know how to use herb around them to cure simple diseases in daily life. This reason inspires us to create the herb database application to be used as standard for research and study in the future. We hope that this application will provide knowledge and benefit to every group of people such as instructors, students, doctors,...
Ferroelectric ceramics and crystals are the main component of many acoustic transducers based on piezoelectric effect. These materials exhibit different types of losses (dielectric, mechanical or coupled, piezoelectric “losses”) which may have strong effect on the resonances of its impedance.
Recent work has shown the potential for lights to act as simple, yet expressive signaling mechanisms for use in a variety of human-robot applications. However, the wide range of robot shapes and sizes makes it difficult for researchers to quickly prototype and evaluate different light configurations and signal designs. In this work, we present the design of ModLight, a modular research tool consisting...
The paper deals with a conception and implementation of selected parts of laboratory experimental receiver for processing Aeronautical VDL2 data link (VHF Data Link mode 2) messages. For acquiring of digitized signal a software defined RTL-SDR receiver is used. Program MATLAB is used for further signal processing. Implementation of message detection, signal filtration, demodulation, symbol and bit...
This paper deals with design of a new protective structure and completes the first step resulting to the preliminary draft of its shape and structural design. The process of designing the protective structure started with creation of the computational model solved in the software environment Ansys Fluent, where the most common cuboid shape of protective structure was assessed on the bases of output...
The process of drawing is one of the main activities during childhood. The drawing dynamics, drawing techniques are on the focus of education science. It is known that the result of the drawing process depends on eye-hand coordination. Testing of the psycho-motoric reactions allows classifying motion and positioning problems. Psychomotor reaction data, compared with the characteristics of the drawing...
This paper presents a three-year participant observation in which the author acted as CTO of a software startup, spanning more than 9,000 hours of direct experience. The author's emails and diary reflections were analyzed and synthesized into a set of nine claims about software engineering work. These claims help shape software engineering research, practice, and education by provoking new questions...
Code smells are sub-optimal coding circumstances such as blob classes or spaghetti code - they have received much attention and tooling in recent software engineering research. Higher-up in the abstraction level, architectural smells are problems or sub-optimal architectural patterns or other design-level characteristics. These have received significantly less attention even though they are usually...
In this paper a modified broadband 1–18 GHz double ridged guide horn antenna (DRGH) with a feeding section including coaxial input and a back shorting plate is introduced. The major differences with the conventional version are in shape of H-plane flares, removal of E-plane flares, shape of ridges and sizes of various parts. Since there is no explanation for the effects of most of the antenna parameters...
This paper proposes an alternative approach to improve the dimensional accuracy of the holes manufactured with Fused Filament Fabrication desktop 3D printers. As opposed to the state of the art techniques, where they scale the input geometric designs according to their predictive and statistical models, the proposed method modifies the interior of the artifacts with respect to the geometric properties...
