This paper details how LINC a coordination middleware, can fasten the development of prototypes that integrate several equipment. A case study of rapid prototyping is presented. It illustrates how a smart parking prototype has been built from several independent and autonomous equipment, coming from different vendors. This has been achieved by parallel development thanks to the resource based approach...
This paper discusses on an experimental platform of an electromechanical simulator able to reproduce the power flows between a railway vehicle and the power supply system. The platform consists of an scaled-down system. It represents an urban DC railway systems in normal and extraordinary operating conditions. It is equipped with hardware and software components, suitable for testing mechanical moving,...
This paper describes a novel speculation technique for the optimization, and simultaneous execution, of multiple alternative traces of hot code regions. This technique, called Speculative Trace Optimization (STO), enumerates, optimizes, and speculatively executes traces of hot loops. It requires hardware support that can be provided in a similar fashion as that available in Hardware Transactional...
There are several researches, which identify the following two problems as main bottlenecks of post-silicon validation: bug detection/localization and coverage calculation. Although FPGA prototyping is considered as pre-silicon verification the coverage calculation and bug localization are as much challenging as for post-silicon phase. This article presents a novel approach to solve the above mentioned...
During the Demo Night, universities and public research institutes will demonstrate their hardware platforms, prototypes and tools. The aim of this event is to present collaborative projects and to demonstrate working solutions. DASIP Demo Night includes a reception with a casual social environment conducive to friendly discussions and networking.
This paper presents a design & implementation of three pole three zero digital controller based on Digital Signal Controller for low voltage synchronous Buck Converter. The proposed control involves one voltage control loop. Analog Type-3 controller is designed for Buck Converter using standard frequency response techniques. Type-3 analog controller transforms to 3P3Z controller in discrete domain...
Due to short — but frequent — sessions of smartphone usage, the fast and easy usability of authentication mechanisms in this special environment has a big impact on user acceptance. In this work we propose a user-friendly alternative to common authentication methods (like PINs and patterns). The advantages of the proposed method are its security, fastness, and easy usage, requiring minimal user interaction...
In this paper a hardware implementation of the finite impulse response narrow band-stop time-varying filter based on the infinite impulse prototype filter is proposed. The notch filter is used for removing power-line interferences from biomedical source, i.e. ECG signal. In order to suppress the transient state of the proposed filter, the pole radius and the pole angle of the prototype filter are...
Overtaking traffic on undivided roadways is one of the major causes of accidents that results in fatalities and severe injuries. This is especially true in developing countries such as India, where roads are narrow, yet traffic is heavy and fast. The primary cause of such accidents is the inability of drivers to gauge the speed and distance of oncoming traffic as well as the impairment of vision due...
How to implement effective interaction design teaching for undergraduates of industrial design is the core content of the paper. Thorough summarizing undergraduates' teaching practice of interaction design, this article discussed a series of problems that were encountered in courses and formative reasons of problems. Research proposed a final solution-- introduction of design practice teaching mode...
Robocar World Championship or briefly OOCWC is a new initiative to create a community of people who share their interest in investigating the relationship between smart cities and robot cars with particular attention to the spread of robot cars in the near future. At the heart of this initiative is the Robocar City Emulator. It is intended to offer a common research platform for the investigation...
Electromyography (EMG) signals can be used to integrate with machines and form one assistive system such as a powered exoskeleton. This paper focuses on the design and development of a low-cost elbow joint powered exoskeleton for human power augmentation, controlled by the EMG. Majority of the hardware has been designed and developed in-house, without using expensively available hardware. A theoretical...
Arbitration policies and predictability enhancement measures typically employ packet priority as the decisive parameter. Though packet timeliness is a key attribute, Network-on-Chip designs rarely consider timeliness as a parameter mostly due to the impracticality of utilising time stamping which relay on the notion of a global time. In this paper, we introduce a low overhead approach where packets...
In this article, we propose a first research about the electroencephalographic signals for supporting in some person whit physical disabilities, for example, the movement of a wheelchair. The brain, along with the heart, are the most important organs of the human being is the center of the nervous system, making complex but important functions such as self-control, planning, reasoning and abstract...
Lightweight mounting systems reduce hardware and labor costs associated with a typical rooftop PV installation. PVMC fabricated innovative lightweight mounts for PV modules that eliminated traditional racking and ballasting materials. Seven (7) prototype systems (each system < 3 kW) using rigid and flexible PV modules from multiple manufacturers were deployed on TPO (Thermoplastic Polyolefin),...
This paper proposes a power conditioning system (PCS) for distributed photovoltaic (PV) applications using a hybrid asymmetric cascaded multilevel inverter with a single PV source. One of the main disadvantages of cascaded multilevel inverters in PV systems is the requirement of multiple isolated DC sources which leads to voltage unbalancing. The proposed PCS uses a single PV source with a flyback...
This paper describes a technological development project in charge of collecting and relaying data using UAVs (Unmanned Aerial Vehicles) from one or more small, low power, modular sensor nodes that can be placed in remote areas or floating on the water surface. The overall characteristics and architecture of the proposed sensor nodes and system around them are described. Field tests for one custom-built...
In this work, we present a brief report on a pilot project based on the concepts of Mobile Remote Experimentation (MRE). The project aims to provide an environment and a model using open source tools that can be replicated, since these are likely to re-use and have low cost, essential factors when it comes to public education, that allows students to perform laboratory practices remotely via mobile...
This paper exposes how we united computervision technology and tangible user interfaces to conceive aninnovative product targeting children audience. Voxar Puzzle isa digital game in which children have to choose a puzzle froma virtual library and assemble it by manipulating physicalblocks. Furthermore, the process used for the development ofthe game platform had innovation in mind. A Blue Oceanstrategy...
An on-chip sine-wave synthesizer design with fast programmability and low hardware cost is presented. The design makes use of a harmonic cancellation technique to digitally synthesize an approximation to a sine-wave, which does not contain lower order harmonic distortions. The remaining higher order harmonics are attenuated with the use of a low pass filter (LPF) to synthesize a spectrally pure sine-wave...
