An IPv6 Passive-Aware Network Routing Algorithm Based on Utility Value Combined with Deep Neural Network

Passive sensing networks can maintain the operation of the network by capturing energy from the environment, thereby solving the energy limitation problem of network nodes. Therefore, passive sensing networks are widely used in data collection in complex environments. However, the complexity of the network deployment environment makes passive sensing nodes unable to obtain stable energy from the surroundings. Therefore, better routing strategies are needed to save network energy consumption. In response to this problem, this paper proposes an IPv6 passive-aware network routing algorithm for the Internet of Things. This method is based on the characteristics of passive sensing networks. By analyzing the successful transmission rate of the network node transmission link, transmission energy consumption, end-to-end transmission delay, and waiting delay of IPv6 packets, the utility evaluation function of the route is obtained. After the utility evaluation function is obtained, the network routing is selected through the utility evaluation function. Then, the utility value and the deep neural network method are combined to train the classification model. The classification model assigns the best routing strategy according to the characteristics of the current network, thereby improving the energy consumption and delay performance of the network.

Cost-effectiveness and cost-utility evaluation of the individual vs. group transdiagnostic psychological treatment for emotional disorders in Primary Care (PsicAP-Costs) v2

The aim of this study is to compare, in cost-effectiveness and cost-utility terms, a brief transdiagnostic cognitive-behavioural therapy in two different modes, individual and group, with the treatment usually administered in primary care (TAU). Participants between 18 and 65 years old and with, according to the pretreatment evaluation, mild to moderate emotional disorders will be randomly allocated to the three clusters. They will be assessed again immediately after treatment and 6 and 12 months later. ClinicalTrials.gov: NCT04847310

Corrigendum: Brief alcohol intervention for risky drinking in young people aged 14–15 years in secondary schools: the SIPS JR-HIGH RCT

During independent re-analysis of the cost data for a PhD thesis, a coding error was identified in one of the sensitivity analyses of the cost-utility evaluation of the trial looking at the effect of excluding from the intervention and control costs the cost of missed school days.

Preparation method of Silver Nano particles

The last few years have perceived the most important development in the field of metals nanoparticle. As they have emerged a highly demanding chemical, physical and biological properties, thereby they employed in the various chemical and pharmaceutical industry. Silver as a metal with exceptional properties, its nanoparticles have devoted significant efforts for their synthesis and utility evaluation. In this review, the most recent and important approaches for the synthesis of silver nanoparticles will be covered along with the use of Ag NPs in a various disciplines especially those that are related to human life such as medicine, drug delivery and water purification. Besides reviewing several different opinions about the risks resulting from the synthesis and use of this type of materials

A Test of Significance of Process on Effectiveness of Teacher Evaluation in Kwekwe Schools of Zimbabwe

Zimbabwe adopted Results Based Management (RBM) in order to evaluate the performance of its workers. For the process to be ‘significant’ and meet the basic attribute of utility, evaluation information should be focused towards predetermined uses. The objective of this study was to assess the significance of the teacher performance evaluation process and examine the relationship between the significance and the effectiveness of the evaluation system of Kwekwe district in Zimbabwe. The study was situated in the pragmatic worldview and underpinned by the Readiness Assessment, Design, Process, Significance (RADPS) conceptual framework. It adopted the convergent mixed method design and the concurrent sampling design. Simple random and purposive sampling techniques were used to select 292 teachers and 12 educators for the quantitative and qualitative research strands respectively. SPSS version 26 was used to analyse the quantitative data and qualitative data were analysed using Atlas ti. 8. Findings show that the evaluation process in the Kwekwe district has no meaningful consequences or implications on effectiveness of the evaluation system. RBM has failed to fulfil both the professional and accountability functions. The inferential statistics proved that the significance of an evaluation process is statistically significant in predicting and influencing the effectiveness of an evaluation system and in the case of Kwekwe district, the evaluation process negatively impacted on the effectiveness of evaluation of teachers. The study findings imply that an evaluation process should be carefully planned and implemented for professional and accountability functions of teachers to be effective.
