    An Overview of Digital Trunked Radio: Technologies and Standards 

    Kunagorn Kunavut (2014)

    Land Mobile Radio (LMR) refers to the two-way radio communication system that allows users sharing the same range of frequency to communicate with the others. LMR can be roughly classified into two main systems which are conventional and trunked radio systems. In conventional system, a frequency band is permanently dedicated to a voice channel. However, using trunked radio system can increase the spectrum efficiency by having pool of frequencies which are temporarily assigned to a group of users called talk group only when required. In tru...

    Experimental Analysis of Performance Comparison on Both Linear Filter and Bidirectional Con dential Technique for Spatial Domain Optical Flow Algorithm 

    Darun Kesrarat; Vorapoj Patanavijit (2013-11)

    Optical flow is a method for classifying the density velocity or motion vector (MV) in a degree of pixel basis for motion classification of image in video sequences. In actual situation, many unpleasant situations usually generate noises over the video sequences. These unpleasant situations corrupt the performance in efficiency of optical flow. In turn to increase the efficiency of the MV, this research work proposes the performance comparison on linear filter and bidirectional confidential technique for spatial domain optical flow al...

    Adaptive Membership Functions for Handover Decision System in Wireless Mobile Network 

    Thanachai Thumthawatworn (2016-03)

    Wireless mobile networks in the future are envisioned to demand more intelligent handover decision mechanisms to achieve seamless mobility and services. Fuzzy logic algorithms were proposed to enhance the handover decision process in recent years. However, most proposed algorithms deploy fixed fuzzy membership functions (FMFs). This approach gives an unsatisfactory network selection performance when different traffic types (service options) are required. In this work, we are proposing a new approach to handover decision system (HDS) design....

    Vendor Selection Strategy for IT Outsourcing: The Weighted-Criteria Evaluation Technique 

    Boonlert Watjatrakul (2012-07)

    Purpose – Most firms select their information technology outsourcing (ITO) vendors based on the two methods of the weighted-criteria evaluation technique – the “qualification score plus the lowest bid price for the highest price score (QS-LBHPS)” and the “qualification score plus the average bid price for the middle price score (QS-ABMPS).” This paper aims to understand whether these two methods provide the same or different results of vendor selection and how the proportional weights of a vendor’s qualification and bid price affect the ve...

    Filtering Test Case Selection for Increasing the Performance of Regression Testing 

    Adtha Lawanna (2016-01)

    Under the concept of using software testing, the problems are preparing the smallest size of the selected test cases, fixing bugs, predicting the estimated testing time and numbers of the tester. The traditional methods are developed to solve these issues. Unfortunately, they cannot be applied for all reasons. Therefore, the filtering test case selection model is proposed to solve these problems and to increase the efficiency of the regression testing. It prepares the methods of filtering, classifying, and selecting the appropriate test cases. ...

    Winley, G. K. (2015)

    A theoretical model of information technology (IT) project management was formulated based on the results of previous studies incorporating transactional and transformational leadership styles, team diversity, and team culture as determinants of team processes and project outcomes. The study addresses the lack of previous studies of IT projects and is concerned with infrastructure and software projects conducted in cross‐functional environments with co‐located teams in the context of Thailand. The model was tested and developed to a final model...

    Performance Analysis of Adaptive Location Update Schemes for Continuous Cell Zooming Algorithm in Wireless Network 

    Tun, Khin Cho; Kunagorn Kunavut (2016-01)

    To reduce the transmitted power of base stations in mobile wireless networks, continuous cell zooming algorithm is a feasible dynamic cell zooming algorithm. In this algorithm, location management is required in order to know the locations of users. Movement-based Update is not compatible and the application of Convention Periodic Update (CPU) scheme in continuous cell zooming algorithm can lead to a high signaling cost. Thus, aiming to highlight the effectiveness of newly proposed location update schemes, Time-Adaptive Periodic Update (TAPU) a...

    Efficient bitstream compression using historical-based grouping and size-based coding rearrangement 

    Thotsapon Sortrakul; Wuthikrai Tharachatr (2009-11)

    Data storage becomes one of the important factors for most of large enterprises in increasing the cost, chip area, and dissipation. Large enterprises usually create redundancy of repeated digital messages through communication and documentary. In order to minimize these kinds of redundant bitstream, this paper presents a novel algorithm for lossless data compression by developing Historical-Based grouping and Sized-Based Coding Rearrangement approaches to reduce the code size used in compress redundant data flows. The Historical-Based groupi...

    CREATININE PREDICTION FROM BODY COMPOSITION A NEURAL NETWORK APPROACH 

    Thitipong Tanprasert; Chularat Tanprasert (2009-12)

    Creatinine, a naturally-produced chemical compound in blood, has been commonly used as a reliable indicator of kidney function. Creatinine level is typically obtained from blood-test. In this paper, a technique for predicting the criticality of creatinine level in blood is presented. The proposed technique takes only body size and mass parameters obtained from advanced weighing scale and body scanner, allowing the prediction to be done more casually. The technique applies a multi-layered feed-forward neural network for developing the predic...

    Hybrid Technique and Competence Preserving Case Deletion Methods for Case Maintenance in Case-Based Reasoning 

    Lawanna, A.; Daengdej, J. (2010-04)

    Case-Based Reasoning (CBR) is one of machine learning algorithms for problem solving and learning that caught a lot of attention over the last few years. In general, CBR is composed of four main phases: retrieve the most similar case or cases, reuse the case to solve the problem, revise or adapt the proposed solution, and retain the learned cases before returning them to the case base for learning purpose. Unfortunately, in many cases, this retain process causes the uncontrolled case base growth. The problem affects competence and performance o...
