Purpose: Sometimes our robot researcher needs a terminal program to exchange the data with the robot or automation device. Nevertheless, the readily available terminal program lacks some functionality that is most relevant to the researcher. We feel that a featured rich terminal program can handle lots of communication overhead for the researcher and relieve them from repetitive and time-consuming tasks. In mind for this, we researched and developed a utility program. We added extra features like automatic send, change dynamic data, etc., so our robot researcher can test the system communication better. In this paper, we demonstrated the utility program in detail. It is built using C#, which is under the Microsoft dot net framework. The code is uploaded to GitHub. Anyone can download and use it. It can be customized for their need. All used classes are available in .cs format. Design/Methodology/Approach: This is the software utility program built by the dot net framework of Microsoft visual studio. It has a graphical user interface (GUI) and some object classes. It has a serial and ethernet interface to test the channel. Once the medium is selected, the application will send whatever is written in the input text box. The Data sending may be an automatic or manual process. In manual mode, after typing the command, we need to press the “Enter” key to send the data. In automatic mode, it will send automatically within the preset interval. The transmit and receive content is displayed inside the list box. Findings/results: sometimes, our project goes into a critical phase. We need to have good tools to overcome the situation immediately. This is a helpful tool to trace the communication-related issue. Using this tool, we can observe the outgoing and incoming data traffic. The robot researcher can use it for their communication-related debug purposes. Originality/Value: Using this terminal program, our robot researcher will get lots of benefits where readily available utility programs cannot provide them. It has some unique features like automatic sending, changing dynamic content, etc. It has a serial and ethernet interface channel so that most of the device communication can be debugged through this interface software.

In the last few years, multicast device-to-device (D2D) cellular networks has become a highly attractive area of research. However, a particularly challenging class of issues in this area is data traffic, which increases due to increase in video and audio streaming applications. Therefore, there is need for smart spectrum management policies. In this paper, we consider a fractional frequency reuse (FFR) technique which divides the whole spectrum into multiple sections and allows reusing of spectrum resources between the conventional cellular users and multicast D2D users in a non-orthogonal scenario. Since conventional cellular users and multicast D2D users shared same resources simultaneously, they generate severe data traffic and high communication overhead. To overcome these issues, in this paper we propose Lagrange relaxation technique to solve the non-convex problem and combinatorial auction-based matching algorithm to select the most desirable resource reuse partners by fulfilling the quality of service (QoS) requirements for both the conventional cellular users and multicast D2D users. Then, we formulate an optimization problem to maximize the overall system performance with least computational complexity. We demonstrate that our method can exploit a higher data rate, spectrum efficiency, traffic offload rate, coverage probability, and lower computational complexity.

Conducted from April 2019 to July 2020, this study aimed to assess the software accuracy in assisting Z-line segmentation by comparing with medical doctors’ detection results and by recording doctors’ satisfaction in scale, time-of-implementation in interactive mode, and integrated mode. For the development of the Z-line detection algorithm, a dataset of 533 high-definition endoscopic WLI (white-light) images in diverse forms of Z-line were collected. The software was subsequently developed in 4 modes, including manual mode, interactive mode (using Superpixels-BPT), automatic mode (using AI algorithm), and integrated mode (the combination of BPT and U-Net). 30 endoscopic images were assigned to 2 groups of doctors (under 2-year experience and over 5-year experience) for the Z-line detection using the software in 4 modes. Time-of-implementation, number of mouse clicks, satisfaction in scales, and IoU (Interception over Union) metric with expert’s ground-truth are used for assessment. The results showed that IoU metrics of interactive and integrated modes in the experimental dataset was 88% with no statistical difference to the IoU value of manual mode, and mean IoU metrics from the results of 4 modes were high, from 86.7 to 90.8%. The mean values of time-of-implementation in interactive mode and integrated mode were not statistically different from manual mode. The median number of mouse-clicks each use in the interactive mode and the integrated mode were 24.5 and 15.5 times, respectively. The software received good feedbacks from the doctors, with the mean values of satisfaction scores of automatic mode, interactive mode and integrated mode are 7.2, 7.3, and 7.2 respectively. The development of the software for detecting endoscopic anatomy landmarks is a novel and feasible research direction in Vietnam. Further studies could focus on detecting some specific lesions classified according to anatomy landmarks.

Mobile Ad hoc Networks (MANET) comprises a collection of numerous mobile nodes that communicates with one other with no dependence on any predefined infrastructure in the network. The characteristics of MANET such as independent, wireless, and self-configuration of MANETs allows the suitability of various application scenarios. Cluster based Flooding is an important issue in the design of MANET where it is an order to manage data traffic as it utilizes a set of chosen nodes to transmit data between two nodes. MANET networks frequently structured with mobile devices for enabling data transmission. An essential process of selecting forwarding set in the inter-cluster flooding. The routing protocol employ in the network often defines the energy efficiency and network performance in ad hoc networks. This paper presents a new deterministic directed flooding scheme (D2FS) for effectively choose the forwarding set for effective inter-cluster flooding. In addition, a Cluster Based Flooding utilizing Fuzzy Logic Scheme (CBF2S) to effectively transmit data is also presented. The devised D2FS model is tested using NS2 tool with respect to the existence of diverse hop counts. An extensive experimentation takes place to prove the superiority of the D2FS with respect to overhead, communication overhead, traffic load, packet delivery ratio and end to end delay.
