Due to the growing demand to reduce the environmental impact, the manufacturing companies of today are encouraged to adopt new green methodologies, strategies and technologies for increasing the energy efficiency of their manufacturing production lines. These solutions have a great impact on several productivity metrics including availability and costs. The continuous pursuit of productivity and particularly...
Emergency systems serve people in utmost circumstances, hence they should be highly dependable. Availability and performance are key aspects in emergency systems. Architectural models, service policies, and redundancies are attributes for defining and evaluating the overall operation of such systems. In this work, we performed the perform ability evaluation of an important emergency system located...
Actuated signal controllers (ASC) are widely deployed to control various intelligent traffic devices. However, there is not enough research on the security of the communication between a control console and the ASC. The communication protocol is SNMP for the management of the ASC. In this paper we will identity the major security threats against the SNMP-based ASC systems and propose possible defense...
In this paper, we present a formal model and analysis for the security extensions of the Domain Name System (DNSsec) in the interactive theorem prover Isabelle/HOL. Based on the inductive approach of security protocol analysis by Paulson in Isabelle/HOL, we show how the protocol can be modelled and important properties are proved. We prove that origin authentication works securely. In order to illustrate...
The contribution of this paper is a conceptual architecture based on intelligent services for manufacturing support systems. Current approaches cannot cope with the dynamism inherent in the manufacturing domain, where unexpected and drastic changes occur at any time and affect cross-boundary systems. Our approach alleviates these issues and focuses on the need for supporting real-time automatic negotiation,...
This paper introduces a method to improve the performance of a Bioelectrical Potential (BEP) based Human-computer interface. The BEP interface used was design to be used by physically challenged patients that remain with the ability to dexterously control a set of superficial muscles. The proposed method uses the BEP signal coming from superficial muscles as a force actuating over a simulated inertia...
In recent years, senior driver-related traffic accidents have been increasing while the number of deaths in these accidents has been decreasing. This also shows the complexity of the composition ratio of drivers to pedestrians in the traffic environment. In order to ensure traffic safety under this environment, not only is advanced technology for vehicle safety necessary but also traffic safety education...
In the context of Design for Environment (DfE) in product development, material selection is particularly important for the product. It affects its design, its manufacturing process, and the environmental impacts over its life cycle phases [1]. For technical or functional reasons, specific materials with best fitting characteristics are needed. Yet, their extraction and manufacturing process causes...
Environmental Open Data has the potential to become a key strategy for the global endeavor of preserving the world's ecosphere. Therefore, this paper aims at researching the status quo of such data in Austria and exploring related advantages and shortcomings. First, the presented survey is motivated and put in perspective to relevant related work. Then, the approach to gaining the datasets is described...
The paper presents an agent-based simulation to model supply chains (SCs) and evaluate the bullwhip effect, an important index to measure the stability of SCs, under the stochastic demand and lead time. We carried out a series of numerical experiments to measure the bull whip effects in two scenarios. In the first scenario with a simple 2-tier SC, the results of simulation were obtained and compared...
Expression recognition or Emotional state recognition using holistic and feature information is the vital step in Driver Assistance System. Many researchers have work on Facial Gesture or Emotion recognition independently. The purpose of the present paper is to deal with Simultaneous Facial Gesture tracking and Emotion recognition with Soft Computing tool like Fuzzy rule based system (FBS). In Human...
Recent studies have shown that improving the light environment in a room increases intellectual productivity, and studies have been carried out with a focus on light color in addition to illuminance and color temperature. This study therefore focuses on color rendering properties in addition to illuminance and color temperature, and is aimed at establishing a more comfortable room environment. In...
The focus of the paper is to develop a simple phenomenological model of McKibben pneumatic actuator which is capable of capturing its inherit nonlinear and varying dynamical characteristics under different load conditions. It will be shown that physical work analysis determines the model structure and phenomenological nonlinear spring term is introduced into the model to capture the response characteristics...
To tackle the twin challenges of sustainable energy supply and climate change, numerous efforts have been made to decarbonize the whole energy systems. Control Engineering, which concerns the automated operation of a machine or system to achieve desired target(s) and to avoid unstable or unintended disruptive behavior, has played a key role in modern industry and across the whole energy system. Advanced...
This paper presents a novel approach for bird species classification based on color features extracted from unconstrained images. This means that the birds may appear in different scenarios as well may present different poses, sizes and angles of view. Besides, the images present strong variations in illuminations and parts of the birds may be occluded by other elements of the scenario. The proposed...
In the field of human-robot interaction (HRI), detection, tracking and re-identification of humans in a robot's surroundings are crucial tasks, e. g. for socially compliant robot navigation. Besides the 3D position detection, the estimation of a person's upper-body orientation based on monocular camera images is a challenging problem on a mobile platform. To obtain real-time position tracking as well...
Developing methods for people tracking on mobile robots is of great interest to engineers and scientists alike. Plenty of research is focused on pedestrian tracking in public areas. Yet, fewer work exists on practical people tracking in home environments with non-static cameras. This paper presents a real time people tracking system for mobile robots that filters asynchronous, multi-modal detections...
The purpose of this study is development of highresolution video see-through display for interactive work support. The interactive work support is a technology that can present appropriate work instructions corresponding to situations to the worker. In order to realize the technology, we are developing a video see-through display that can present work instructions. The video see-through display is...
This paper proposes a general method of robotic imitation learning. In this method, robots learn inner common features of demonstrations, which are largely different from each other, by analyzing the similarities among the features of the demonstrations. Adaptive generation methods are related to each feature. At the generation stage, given new task-relevant constraints, robots can generate motion...
Complex architectural artifacts and industrial systems are increasingly being designed with the help of virtual prototypes. In these virtual environments users can interact with specific features of a simulation to evaluate functional aspects or learn complex operations before system construction or while unaccessible. A key issue for a virtual prototype-based design cycle is the possibility to easily...
