In the universities where undergraduate Computer Engineering (CE) and Computer Science (CS) programs are offered, people often wrongly argue that the CE program should be offered under College of Engineering instead of under the college where CS program is offered, this is mostly because they think CE program has “Engineering” word in it. This school of thought does not realize that by this, it will...
There are some issues with the adoption of information technology of infrastructure library (ITIL). The common issue comes from customers that always need excellent services. On the other hand, there are employees acting as an internal element of enterprise who need to be motivated while delivering the services. It has been known that the pressure at work and employees' personal problem can cause...
Nowadays, an efficient image segmentation process as a preprocessing step provides important cues for numerous applications in human pose estimation, computer vision, objects recognition, tracking and image analysis. Many of the existing segmentation algorithms have high computational cost because of the segmentation foreground object from the large and complex-background images. But, some objects...
Multi-plane light conversion (MPLC) [1], [2] consists of a series of phase masks separated by a Fourier transform or free-space propagation and is illustrated conceptually in Fig. 1(a). Through this cascaded sequence of phase masks, and the diffraction which occurs between the masks, it is possible to implement arbitrary unitary spatial transformations. That is, any spatial input basis can be converted...
Scoring short answer question (consisting of at most 100 words) requires a special treatment, particularly on the term weighting process. With such limitation, it is therefore infeasible to have term weighting with term frequency model because the frequency of term appearance is very rare. This paper proposes a new method, named Weighted Cosine Coefficient. The experiment result shows that Weighted...
Offline handwritten signature is still widely used for person verification in financial and business transactions. Most research in offline handwritten signature at-tempts to improve feature extraction and classification for the better recognition rate. The deformation and unsteadiness of handwritten signatures, such as direction, declination, and size, are also the key factors sensitive to recognition...
Circular Extreme learning machine (C-ELM) is the one extended Extreme Learning Machine (ELM). It has the same structure as ELM and Circular Back Propagation (CBP) to make it can mapping both linear and circular decision boundaries. The activation function is the one main point to define the decided boundaries. Many activation functions have been proposed. This paper proposes q-Gaussian activation...
The purpose in this study is visualizing brain functional activities during taking a favorite food using Near Infra-Red Spectroscopy (NIRS). Many appointments and systems that aim to provide happiness for improving quality of life in the users have been constructed. The creations must integrate a common and plausible happiness indicator into their module; however, almost all of them do not have the...
Additional intermittent PV generation and variability load profiles can cause problems in voltage regulation of power systems. Nowadays, PV does not participate in the system voltage control; it can cause a voltage increase or decrease and cause voltage fluctuation disturbance along the feeder. However, the situation can be different if PV participated in voltage control. This paper proposes an approach...
The aims of this paper is to study and to compare the performance of the three most likely popular PLL strategies that could be found in renewable on-grid power generation control systems: SRF-PLL, DSRF-PLL and DSOGI-PLL. In the on-grid power generation, The PLL has responsibility to acquire grid phase angle and positive-negative sequence components of the grid voltage vector which are required for...
Distributed generation (DG) is a distributed generator that employs on the distribution system. The aims of DG in distribution system are to improve the voltage profile, to increase spare capacity, and to reduce the power losses. DG installation on the distribution system needs consideration of optimal capacity and optimal placement. If DG has placed in incorrect location so it can damage and interference...
Knowledge organizer is a medium to organize the objects of knowledge. The organizer that use semantic representations provide an advantage, because it can be understood by the computing machinery. The organized objects as resources to increase knowledge should be able shared through such as Learning Management System (LMS) which generally use a SCORM (Shareable Content Object Reference Model) as standard...
Flow state, as a psychological experience is one of important aspects in a learning environment. Involving a psychological experience as a context in a context aware personalized e-learning becomes very important. It is due to that engagement and interest in a learning process are determined by its psychological conditions. However, development of a model personalized context aware e-learning by considering...
In Association rules mining, the task of finding frequent itemsets in dynamic database is very important because the updates may not only invalidate some existing rules but also make other rules relevant. In this paper, we propose a new algorithm to maintain frequent itemsets of a dynamic database in the case of record insertion as well as deletion simultaneously. Basically, the proposed algorithm...
Nowadays, an industrial wireless sensor (IWS) is interested and widely used by various industries. There are many industries trying to adopt qualified IWS products in competitive market for gaining advantage. The challenge in choosing IWS includes not only the price, but also several factors, e.g., operating frequency, data rate, output power, interface, brand, and so on. These factors cause difficulty...
This paper present recommendation of metadata element set for ethnophytomedicine resources from scientific journal publication to support the sharing and reuse among stakeholders. Ethnophytomedicine itself is traditional knowledge of local people about use of native medicinal plant. Development of metadata has been through utilizing four approaches, i.e. domain-analysis, derivation analysis, system-centric...
Studies involving simulator are often used to support scientific research, such as research on post-traumatic stress disorder (PTSD) and fear of flying. However, the use of driving simulator may produce biomedical side effect, namely cybersickness. Although the research of simulator sickness has been done before, there is no study that focuses on how cybersickness affects visual attention during day...
In this paper we propose a new algorithm to rearrange handwriting for Thai online handwriting beautification. First, we segment the line into the right group (Line of tone level, Line of upper level, Line of body level and Line of lower level). Then we calculate the center point of each character by x average and y average value. After that we find the moving path that includes two perpendicular marks...
Technical analysis is a method to forecast market price quickly. It has a paradigm which stated that history repeats itself. According to technical analysis theory, historical data is an important variable to predict the future. The previous variables that used to calculate are open, high, low, and close price. There are many technical ways to analyze and predict trends using one kind of pair. This...
A quadrotor is needed by geologists to do surveillance and monitoring in several disaster-prone areas. Therefore, quadrotors which are able to perform autonomous hovering in order to move from one location to another are required. Based on the problem, This paper presents the trajectory and altitude control for autonomous hovering of quadrotor by using fuzzy logic controller. This algorithm is applied...
