Software professionals do not always clarify what they mean by their effort estimates. Knowing what is meant by an estimate is, however, essential when adding individual effort estimates from a work breakdown structure to find the estimated total effort. Adding the most likely instead of the mean effort of a set of cost elements may result in substantial underestimation of the total effort. In a survey...
Recently, Projection Mapping is attracting attention as a new approach for visual expression method. In order to perform large-scale Projection Mapping, multiple projectors are required. In this paper, we propose a new representation technique by various attempts. To determine more impressive visual expression, we have developed Projection Mapping and devised Prodigious Mapping. We have set the projector...
Measurement-Based Probabilistic Timing Analysis (MBPTA) has been recently proposed as a viable method to compute probabilistic worst-case execution time (pWCET) bounds for programs with hard real-time constraints. As a key trait, MBPTA needs a comparatively small number of observation runs, made on execution platforms to which MBPTA can be applied, to project the tail of the probability of occurrence...
Traditional technology of experimental modal analysis bases on the known input and output signals, and utilizes integrated information of both the excitation and responses to identify the modal parameter. In most of the actual conditions, only the response data is measurable while excitations are unknown. Thus modal parameter must be extracted only from responses. In allusion to this limitation, this...
The process of teaching and learning geometry should be implemented more effectively because of its importance in students' daily lives. Therefore, a study that aimed to develop activities based on Van Hiele's phases of learning geometry using Geometer's Sketchpad (GSP) software was conducted. The developed activities were then incorporated into a learning kit named Geo-V. An ADDIE model was taken...
This paper reports the development and experiments of an underwater 6-DOF gripper robot. The developed gripper robot is a human-portable remotely operated vehicle (ROV) that weighs approximately 31 kg in air. The most important feature of this robot is that it can grasp cylindrical objects of 50–500 mm diameter, and handle them in 6 DOF. We also developed a dedicated operating device to use the gripper...
Autism is a disorder of neural development characterized by impaired social interaction and verbal and non-verbal communication, and by restricted, repetitive or stereotyped behavior. Visual supports can alleviate these challenges by juxtaposing communication with visual cues. In this paper, a "Rehabilitation Training System (RTS)" for children with autism is developed. The "RTS"...
Using amplitude tapering to improve the radiation pattern of a conformal antenna on a surface that changes shape with time has been studied and is presented in this paper. In particular, a six element array was attached to a wedge-shape conformal surface with bend angles 10 degrees, 20 degrees, 30 degrees, 40 degrees, 45 degrees and 50 degrees and the amplitudes of each element were changed to improve...
Building Information Modeling is considered by the scientific literature as an emerging trend in the architectural documentation scenario, as it is basically a digital representation of physical and functional features of facilities, serving as a shared knowledge resource during their whole life cycle. BIM is actually a process (not a software, as someone indicated), in which different players act...
This paper presents two new developments for as-built BIM modeling of historical buildings. The first is a new library of interactive parametric objects designed for modeling classical architectural elements from survey data. These library objects are dynamic and have parameters that can alter the shape and size of objects for multiple uses and not just once off static modeling. The parametric architectural...
GRAphe Fonctionnel de Commande Etape Transition (GRAFCET) is a powerful graphical modeling language for the specification of discrete event systems and an international standard since 1988. Since GRAFCET is a specification language and not a programming language, a GRAFCET specification (Grafcet) still has to be interpreted manually, e.g. as a Programmable Logic Controller (PLC) program according...
Paper documents still represent a large amount of information supports used nowadays and may contain critical data. Even though official documents are secured with techniques such as printed patterns or artwork, paper documents suffer from a lack of security. However, the high availability of cheap scanning and printing hardware allows non-experts to easily create fake documents. As the use of a watermarking...
Migrating software product variants which are deemed similar into a product line is a challenging task with main impact in software reengineering. To exploit existing software variants to build a software product line (SPL), the first step is to mine the feature model of this SPL which involves extracting common and optional features. Thus, we propose, in this paper, a new approach to mine features...
Road sign recognition is a key component in autonomous vehicles and also has applications in driver assistance systems and road sign maintenance. Here an algorithm is presented using the Xilinx Zynq-7020 chip on a Zedboard to scan 1920x1080 images taken by an ON Semiconductor VITA-2000 sensor attached via the FMC slot. The PL section of the Zynq is used to perform essential image pre-processing functions...
The aim of this study is to investigate the question: “Can Information and Communications Technology (ICT) helps to improve primary school students' geometry achievements for rectangles?” The applied educational software consisted of a story and several activities with and without the use of computers which were designed following the background of Realistic Mathematics Education for geometry concepts;...
Software conflicts arising because of conflicting changes are a regular occurrence and delay projects. The main precept of workspace awareness tools has been to identify potential conflicts early, while changes are still small and easier to resolve. However, in this approach conflicts still occur and require developer time and effort to resolve. We present a novel conflict minimization technique that...
Low-fidelity prototyping has been increasingly adopted in software development to facilitate the communication between the developer and the end-user, since it can be simply realised without the need for programming. However, this technique is not mature enough as it lacks a systematic approach to build prototypes and capture user feedback. In this paper, we present a method that provides a systematic...
This paper takes the dichloropropane tank area in a chemical company in service for an example, and adopts the fire simulation software FDS to make numerical simulation for the whole-area pool fire accident in the dichloropropane tank. The variation of flame and the flue gas in the combustion process of pool fire is obtained from the simulation. For the flame, in the early pool fire, the flame is...
This paper presents an application of Augmented Reality (AR) in Rapid Prototyping (RP) of non-textured rigid curved surfaces. By enhancing the prototypes with AR, evaluation of its design and aesthetic concepts in real-time becomes easier, saving time and production costs. In our application, no fiducial markers are required and the CAD model used to build the prototype is applied in an edge-based...
People now use photo browsing, photo and video slideshow, and illustrated text to share stories about their lives in pictures, however, these popular mediums are far from perfect. Some are not expressive enough for sophisticated storytelling, while others inevitably have a high usage threshold and involve a great deal of efforts. In this paper, we propose a framework for comic-based computer-aided...
