The article presents technical solutions that provide measurement and registration of the main parameters of the movement of an autonomous underwater vehicle (AUV) when towing on the surface of a repeater float, taking into account the influence of a communication cable. The equipment of the complex allows measuring the tension vector of the communication cable at the attachment points to the AUV and the float towed along the surface. The structure of the measuring complex and the architecture of its software are determined, which allow integrating into a common file data on the speed and geographical coordinates of a repeater float equipped with satellite navigation means with the parameters of the AUV motion determined by the hydroacoustic navigation system, as well as on the projections of the tension vectors of the ends of the communication cable. The available element base of the complex has been determined, which provides measurement of the listed parameters in the required range and with a given accuracy. The authors have developed an algorithm for determining the projections of the cable tension vector on the axis of the associated coordinate system of the apparatus and the float by the measured angles of deviation of the corresponding measuring modules from the vertical. It is important to note that the complex provides translation of the measured parameters to the storage of the on-board computer of the AUR, where they are recorded as a file of time-synchronized data with the possibility of further graphoanalytic processing and use in further parametric identification of the dynamics model of the communication cable.

One of the skills that must be possessed by a teacher to support his professional competence is communication skills. This study aims to examine the influence of the Project-Based Learning (PjBL) model on improving the communication skills of prospective physics teachers in terms of learning styles. The method used is quantitative research with one group pretest-posttest design. The sample consisted of 46 prospective physics teachers at one of the universities in the city of Mataram. The instruments used consisted of a communication skills assessment sheet and a learning style questionnaire (Visual, Audio, and Kinesthetic). The collected data were then analyzed by calculating the N-gain and t-test. The results of data analysis showed that the average communication skills of prospective physics teachers for all learning style groups (Visual, Audiotorial, and Kinesthetic) experienced an increase in the moderate category (N-Gain = 0.64). To find out the difference in the improvement in the communication skills of prospective physics teachers in terms of learning styles, a comparative statistical test was carried out using the t-test. Based on the results of the t-test at the 95% confidence level (a = 0.05), it shows that there is a significant difference in improving communication skills between prospective physics teachers who have visual, auditory, and kinesthetic learning styles. Prospective physics teachers who have a kinesthetic learning style tend to experience a greater increase in communication skills when compared to the visual and auditory learning styles groups.

This article aims at prioritizing the barriers that hinders deployment of Lean Six Sigma with sustainability cogitations in manufacturing organizations. The barriers were identified from literature and an Interpretive Structural Modeling (ISM) approach was deployed for prioritizing them. Based on the application, the most dependent and driving barriers that hinders the LSS deployment with sustainability cogitations were prioritized. Upon the selected barriers the barrier "Non supportive Leadership", occupy the bottom of the ISM hierarchy and the barriers Non availability of defect monitoring mechanism, Lack of vision for sustainable LSS and Improper communication model occupy the top position of the ISM model. The performed case helped in prioritization of the barriers that supports LSS adoption with sustainable cogitations. This developed approach will be helpful for managers and deployment consultants to systematically concentrate on removing the key barriers and to deploy LSS with sustainable cogitations.

The growth of modern communication systems into 5G deployments has incorporated the ultra-dense network (UDN) concept to provide high-throughput user-centric wireless access. Cognitive Radio (CR) can facilitate the integration of UDNs with legacy systems without the immediate need for allocation of new spectrum which would lead to substantial increase in cost. Thus, the CR-based UDN requires efficient spectrum sensing to correctly identify the unutilized frequency bands. This simulation study emphasizes the strengths and limitations of the most popular algorithm of this kind, energy detection (ED). It is implemented in cognitive access points (CAPs) of an UDN, which determine the spectrum occupancy and allocate the available resource to their mobile users. The applicability of ED-based spectrum sensing is assessed via the primary system's signal-to-noise ratio (SNR) distribution as measured by the CAPs, and the probability of detection. A prominent probabilistic signal propagation model for communications in UDNs is applied. In addition, the CR-based UDN's potential throughput gains are evaluated in terms of the CAPs' deployment density. The performance metrics are estimated via extensive simulations.

The traditional community detection method can only find the tightly connected structure, but the structure of the real network is hierarchical and diverse. Based on the minimum Description Length (MDL) principle, proposed a model consisting of the core node and 4 basic structures to represent the complex network and put forward a formula to calculate the minimum description length of network. First, delete the core in the network and get the hierarchical division, then decompose and merge the non-core network, and get the final network partition until the description length is minimal. Experimental results on real network dataset show that this method has better network compression effect, can get the hierarchical and diversified characteristics of the network, and get more realistic network partition.

In recent years, second generation of internet-based services such as weblog has become an effective communication tool to publish information on the Web. Weblogs have unique characteristics that deserve users' attention. Some of webloggers have seen weblogs as appropriate medium to initiate and expand business. These webloggers or also known as direct profit-oriented webloggers (DPOWs) communicate and share knowledge with each other through social interaction. However, survivability is the main issue among DPOW. Frequent communication with influential webloggers is one of the way to keep survive as DPOW. This paper aims to understand the network structure and identify influential webloggers within the network. Proper understanding of the network structure can assist us in knowing how the information is exchanged among members and enhance survivability among DPOW. 30 DPOW were involved in this study. Degree centrality and betweenness centrality measurement in Social Network Analysis (SNA) were used to examine the strength relation and identify influential webloggers within the network. Thus, webloggers with the highest value of these measurements are considered as the most influential webloggers in the network. [ABSTRACT FROM AUTHOR]
