The rapid development of cellular communication technology is inseparable from various problems especially on signal quality. In outdoor areas, the performance of eNodeB that is not optimal may cause communication failure. This research was conducted with the drive test on the L_BUNDARANRENON_PL, L_AKABA_PL and L_MYAMIN_CR to obtain signal quality parameters at Renon cluster area. The results of the drive test obtained compared to the simulation using the Atoll radio planning software with the Hatta Cost-231 propagation model and the Standard Propagation Model. From the comparison results, the margin value is used as a correction factor. The comparison results obtained based on the quality of SINR, The result of using the Standard Propagation Model is closer to the drive test measurement results than using Cost-231 Hatta. However, based on the quality of RSRQ, both propagation models yield almost the same results. Here are found that the correction factor for SINR obtained the Cost-231 Hatta propagation model of 6.15 dB and the Standard Propagation Model model of 6.11 dB. While for RSRQ correction factor the margin for both propagation models is -2 dB

With the rapid development of science and technology, the application of wireless sensor networks (WSNs) is more and more widely. It has been widely concerned by scholars. Viruses are one of the main threats to WSNs. In this paper, based on the principle of epidemic dynamics, we build a SEIR propagation model with the mutated virus in WSNs, where E nodes are infectious and cannot be repaired to S nodes or R nodes. Subsequently, the basic reproduction number R0, the local stability and global stability of the system are analyzed. The cost function and Hamiltonian function are constructed by taking the repair ratio of infected nodes and the repair ratio of mutated infected nodes as optimization control variables. Based on the Pontryagin maximum principle, an optimal control strategy is designed to effectively control the spread of the virus and minimize the total cost. The simulation results show that the model has a guiding significance to curb the spread of mutated virus in WSNs.

We present the vehicle routing problem with potential demands and time windows (VRP-PDTW), which is a variation of the classical VRP. A homogenous fleet of vehicles originated in a central depot serves customers with soft time windows and deliveries from/to their locations, and split delivery is considered. Also, besides the initial demand in the order contract, the potential demand caused by conformity consuming behavior is also integrated and modeled in our problem. The objective of minimizing the cost traveled by the vehicles and penalized cost due to violating time windows is then constructed. We propose a heuristics-based parthenogenetic algorithm (HPGA) for successfully solving optimal solutions to the problem, in which heuristics is introduced to generate the initial solution. Computational experiments are reported for instances and the proposed algorithm is compared with genetic algorithm (GA) and heuristics-based genetic algorithm (HGA) from the literature. The comparison results show that our algorithm is quite competitive by considering the quality of solutions and computation time.

With the rapid development and wide use of MANET, the quality of service for various businesses is much higher than before. Aiming at the adaptive routing control with multiple parameters for universal scenes, we propose an intelligent routing control algorithm for MANET based on reinforcement learning, which can constantly optimize the node selection strategy through the interaction with the environment and converge to the optimal transmission paths gradually. There is no need to update the network state frequently, which can save the cost of routing maintenance while improving the transmission performance. Simulation results show that, compared with other algorithms, the proposed approach can choose appropriate paths under constraint conditions, and can obtain better optimization objective.

Perioperative bleeding occupies a leading place among all surgical complications and, despite the rapid development of surgery, remains relevant to this day. In addition to an increase in mortality, bleeding can cause the development of other postoperative complications, which lead to disability of patients and to a decrease in the quality of life in all age groups. Most perioperative bleeding are caused by technical errors. This article reviews the problem of perioperative bleeding from the point of view of impaired coagulation capabilities of the body. The main etiopathogenetic features of hemostasis during the development of this complication are considered. The analysis of postoperative complications, which were directly or indirectly caused by bleeding during or after surgery, is presented. The prevalence of these complications in various areas of surgery has been demonstrated. More detailed study of the hemostasis system and the identification of predictors of hemostasis difficulties before the surgery may cause an improvement in the results of surgical treatment and reduce the number of postoperative complications and the duration of hospital stay. Accordingly, this will lead to a decrease in the cost of treatment and an increase in patient satisfaction with the medical care. In connection with the above, there is a great interest among surgeons and anesthesiologists in preventing the development of perioperative bleeding.

Compressive sensing is one of teh cost effective solution towards performing compression of heavier form of signals. We reviewed the existing research contribution towards compressive sensing to find that existing system doesnt offer any form of optimization for which reason the signal are superiorly compressed but at the cost of enough resources. Therefore, we introduce a framework that optimizes the performance of the compressive sensing by introducing 4 sequential algorithms for performing Random Sampling, Lossless Compression for region-of-interest, Compressive Sensing using transform-based scheme, and optimization. The contribution of proposed paper is a good balance between computational efficiency and quality of reconstructed medical image when transmitted over network with low channel capacity. The study outcome shows that proposed system offers maximum signal quality and lower algorithm processing time in contrast to existing compression techniuqes on medical images.

ABSTRACT The use of pre-sprouted seedlings in the implantation of sugarcane crops not only reduces the establishment period and production costs, but also has other advantages, such as a lesser requirement of propagules (stems) and greater phytosanitary control of the seedlings, when compared to conventional planting. Commercial substrates are also expensive and their use increases the cost of seedlings. This study aimed to evaluate the quality of sugarcane pre-sprouted seedlings grown on substrates with different proportions of decomposed babassu palm stem (DBPS), as well as to recommend the substrate formulation that provides the most favorable environment for the growth and development of sugarcane pre-sprouted seedlings. For preparation of the substrate (S), DBPS and soil were used in the following proportions: S1: 0 % of DBPS + 100 % of soil; S2: 20 % of DBPS + 80 % of soil; S3: 40 % of DBPS + 60 % of soil; S4: 60 % of DBPS + 40 % of soil; S5: 80 % of DBPS + 20 % of soil; S6: 100 % of DBPS + 0 % of soil. The use of S2 and S3 considerably improved the seedling quality parameters, such as sprout diameter and length, number of leaves and total, shoot and root dry mass. However, from an economic point of view, S2 is recommended for use.

Abstract The relevance of the topic of scientific research is associated with the use of new liquid fertilizers and a growth regulator in spring wheat crops to increase the yield and quality of grain in the central zone of the Orenburg region. Ensuring food security today is becoming one of the most urgent tasks set by the government of the Russian Federation for domestic agriculture. To solve this problem, it is necessary, first of all, to increase the yield of agricultural crops, rationally using all the factors affecting it. One of these factors is the timely and sufficient application of mineral fertilizers, the cost of which largely determines the size of the cost of production. The emergence of precision farming is associated, first of all, with the improvement of all types of agricultural machinery and technologies, as well as with the rapid development of computer technology, methods of computer modeling and information technology. The integrating basis of the technology is geographic information systems that allow registering and processing information characterizing the state of soil and crops. This information makes it possible to effectively use one of the most significant resources in crop production - mineral fertilizers.

Abstract Objective Transarterial radioembolization (TARE) offers a minimally invasive and safe treatment option for primary and metastatic hepatic malignancies. The benefits of TARE are manifold including prolonged overall survival, low associated morbidities, and improved time to progression allowing prolonged treatment-free intervals. The rapid development of new systemic therapies including immunotherapy has radically changed the treatment landscape for primary and metastatic liver cancer. Given the current climate, it is critical for interventional oncologists to understand the benefits of TARE relative to these other therapies. Therefore, this report aims to review quality-of-life outcomes and the cost comparisons of TARE as compared with systemic therapies.
