Energy sink-holes avoidance method based on fuzzy system in wireless sensor networks

The existence of a mobile sink for gathering data significantly extends wireless sensor networks (WSNs) lifetime. In recent years, a variety of efficient rendezvous points-based sink mobility approaches has been proposed for avoiding the energy sink-holes problem nearby the sink, diminishing buffer overflow of sensors, and reducing the data latency. Nevertheless, lots of research has been carried out to sort out the energy holes problem using controllable-based sink mobility methods. However, further developments can be demonstrated and achieved on such type of mobility management system. In this paper, a well-rounded strategy involving an energy-efficient routing protocol along with a controllable-based sink mobility method is proposed to extirpate the energy sink-holes problem. This paper fused the fuzzy A-star as a routing protocol for mitigating the energy consumption during data forwarding along with a novel sink mobility method which adopted a grid partitioning system and fuzzy system that takes account of the average residual energy, sensors density, average traffic load, and sources angles to detect the optimal next location of the mobile sink. By utilizing diverse performance metrics, the empirical analysis of our proposed work showed an outstanding result as compared with fuzzy A-star protocol in the case of a static sink.

Effects of climate conditions, mobility trends, and countermeasures on the COVID-19 outbreak in Japan

BackgroundAs of mid-December the third wave of COVID-19 infection in Japan was larger than the prior two waves. Therefore, the “Goto Travel Campaign” (GTC) was presumed as the main cause of the third wave.ObjectWe evaluated GTC effects considering climate conditions and mobility. Method: We regressed R(t) on temperature, humidity, mobility, and countermeasures. Results: Estimation results indicate that temperature was a negative and significant influence; mobility was positive and significant. The emergency state and GTC were negative and significant.Discussion and ConclusionEstimation results show that R(t) would increase by 0.52 if the temperature were to decline by 20°C. To cancel this effect, going out should be reduced by 50%. We conclude that GTC did not raise infectiousness.

THEORETICAL BASES OF INFORMATION AND INTELLECTUAL COMPETENCE OF FUTURE TEACHERS OF INFORMATICS

This article reviews the research of scientists on general information and intellectual competence and gives a definition of information and intellectual competence. The possibility of digitization of education for the formation of information and intellectual competence of future teachers of computer science was studied. The structure of the information and intellectual competence of the future teacher of computer science is theoretically substantiated and formulated. The information and intellectual competencies of students were determined by the criteria of knowledge, skills and potential and presented in tabular form. The sample questions to determine the information and intellectual competence of students are based on knowledge mobility, method flexibility and critical thinking. To perform the situational task, we divided the level of performance of students into informational, improvisational, heuristic, considered laboratory work at the information level, independent work of the student with the teacher at the improvisational level and independent work of the student at the heuristic level. A generalized algorithm for the formation of information and intellectual competencies of students in the context of digitalization of education has been developed.

Immediate effects of spinal manipulation in pain and global joint mobility in patients with chronic nonspecific low back pain

Objective: The aim of this study was to analyze the immediate effects of applying a manipulative intervention on chronic non-specific back pain and increasing global joint mobility. Method: A cross-sectional, randomized, single-blind study was carried out, consisting of 19 women aged between 18 and 55 years old, separated into two groups: Experimental Group (EG = 10) and Control Group (CG=9). The evaluation consisted of a physical examination, Rolland Morris questionnaire, fingertip-to-floor test, Visual Analogue Scale (VAS), and pressure algometry (L5) before and after the manipulative intervention. The EG was submitted to five vertebral manipulations, two in the bilateral pelvis region, one in the middle thoracic region (T5-T7) and two in the bilateral cervical region at the C3 level. The CG was submitted to two placebos manipulative techniques, being positioned in right and left lateral decubitus position for 10 seconds each, in the same position of global pelvic manipulation, but without the manipulative impulse (thrust). Results: The results were statistically significant in the EG in the reduction of sensation of pain (p<0,001) and the increase of overall joint mobility (p<0,05) when comparing pre and post intragroup moments. There were no statistically significant differences in relation to pain threshold evaluated in pressure algometry. Conclusion: It is concluded that a manipulative intervention is able to reduce the pain and to increase the global mobility immediately after its accomplishment.

Smart Handoff Technique for Internet of Vehicles Communication using Dynamic Edge-Backup Node

A vehicular adhoc network (VANET) recently emerged in the the Internet of Vehicles (IoV); it involves the computational processing of moving vehicles. Nowadays, IoV has turned into an interesting field of research as vehicles can be equipped with processors, sensors, and communication devices. IoV gives rise to handoff, which involves changing the connection points during the online communication session. This presents a major challenge for which many standardized solutions are recommended. Although there are various proposed techniques and methods to support seamless handover procedure in IoV, there are still some open research issues, such as unavoidable packet loss rate and latency. On the other hand, the emerged concept of edge mobile computing has gained crucial attention by researchers that could help in reducing computational complexities and decreasing communication delay. Hence, this paper specifically studies the handoff challenges in cluster based handoff using new concept of dynamic edge-backup node. The outcomes are evaluated and contrasted with the network mobility method, our proposed technique, and other cluster-based technologies. The results show that coherence in communication during the handoff method can be upgraded, enhanced, and improved utilizing the proposed technique.

The Effectiveness of Kinesiotaping for Patients with Fractured Ribs: A Single-subject Experimental Design

Purpose: Kinesiotape is an elastic, adhesive tape applied to the skin that has been used extensively to reduce pain associated with various musculoskeletal conditions. Its use in the setting of fractured ribs is less clear. The aim of this preliminary study was to investigate the effect of kinesiotaping for patients with rib fracture(s) on pain levels, pulmonary function, and mobility. Method: We prospectively evaluated five patients admitted with fractured ribs using a single-subject experimental ABAB design. Each phase lasted 24 hours with kinesiotape applied during B phases. All participants received usual medical, nursing, and allied health care. Outcome measures included pain levels (participant-rated), pulmonary function, and maximum mobility. The occurrence of skin irritation was tracked. Results: Considerable variability was seen between- and within-participants for pain levels. There was some evidence, albeit inconsistent, that pain levels were lower when the kinesiotape was in situ compared to when it was not. Pulmonary function and mobility levels showed no consistent pattern between intervention phases. Skin irritation occurred in one participant and another required escalation of medical therapy for pneumonia. Conclusions: Kinesiotaping may reduce pain for patients with fractured ribs but further research, preferably randomized controlled trials with homogenous samples and standardized medication regimens, is required to confirm its effectiveness in the acute care setting.

Analysis effects of oil viscosity and temperature on orbit of ring gear in internal gear motor and pump

Effect of oil temperature and viscosity on the ring gear orbit in the internal gear motor and pump is analyzed in this study. The mobility method is used to calculate the ring gear orbit. The mathematical model of oil viscosity and temperature is then integrated into the mobility method. The simulation results point out that the oil temperature and viscosity have great effect on the eccentricity, position angle and minimum oil film thickness. The metal - to - metal contact phenomenon occurs if internal gear motor and pump operates under high values of oil temperature or low values of oil viscosity conditions.
