Cellular networks are expanding massively due to high data requirements from mobile devices. This has motivated base station densification as an essential requirement for the 5G network. The implication is obvious benefits in enhanced system capacity, but also increased challenges in terms of interference. One important interference management technique which has been widely adopted in cellular networks is frequency reuse. In this article, an analysis is presented based on network interference and energy expended by base stations in downlink communication when Soft frequency reuse (SFR) is deployed. A framework is presented that captures the bandwidth overlaps in SFR across base station assignments, computes the interference probabilities arising and derives new performance equations which are verified using simulations. Results show an improvement of over previous SFR implementations that do not consider the interference probabilities. Thus, a more in-depth and accurate modelling of SFR in 5G networks is achieved. Furthermore, the downlink power allocation is investigated as against other parameters like the center ratio and edge bandwidth. The result shows that signal-to-interference-noise ratio (SINR) and spectral efficiency give different performance under energy consideration. A framework is developed on how to tune a base station to achieve desired network performance in user SINR or cell spectral efficiency depending on the operator’s preference.

Infectious disease caused by infection of Mycobacterium tuberculosis is called tuberculosis (TB). A common method in detecting TB is by identifying number of mycobacterium TB in sputum manually. Unfortunately, manually calculation by pathologists take a relatively long time. Previous researches on TB bacteria were still limited to detect the absence or presence of mycobacterium TB in images of sputum. This research aims are identifying number of mycobacterium TB and determining accuracy of classification TB severity by approaching nonparametric Poisson regression model and applying an estimator namely local linear. Steps include processing of image, reducing of dimension by applying partial least square and discrete wavelet transformation, and then identifying the number of mycobacterium TB by using the proposed model approach. In this research, we get deviance values of 28.410 for nonparametric and 93.029 for parametric approaches and the average of classification accuracy values for 4 iterations of 92.75% for nonparametric and 85.5% for parametric approaches. Thus, for identifying many of mycobacterium TB met in images of sputum and classifying of TB severity, the proposed identifying method gives higher accuracy and shorter time in identifying number of mycobacterium TB than parametric linear regression method.

Water scarcity has become the most important challenge facing the world and a source of fear to the global community from the spread of famines due to the lack of agricultural production. For this reason, researchers seek to optimize the use of food resources, including water wealth. This project contributes to the legalization of the use of water resources. One of these methods is to solve the problem of a decrease in water resources, is drip irrigation systems. An affordable system was developed using soil moisture FC-28 hygrometer sensor compatible with arduino uno R3 and sending electrical signals based on voltage difference due to increased or decreased water in the soil to the monitor through the arduino for decision to operate irrigation pumps. The system is controlled by a software that allows the user to know the current state of the soil to choose the type of plant to determine the amount of water and the possibility of adding new types of plants to the program library and other features.

Traffic management inside software-defined data centre networking Tariq Emad Ali; Ameer Hussein Morad; Mohammed A. Abdala

In recent years, data centre (DC) networks have improved their rapid exchanging abilities. Software-defined networking (SDN) is presented to alternate the impression of conventional networks by segregating the control plane from the SDN data plane. The SDN presented overcomes the limitations of traditional DC networks caused by the rapidly incrementing amounts of apps, websites, data storage needs, etc. Software-defined networking data centres (SDN-DC), based on the open-flow (OF) protocol, are used to achieve superior behaviour for executing traffic load-balancing (LB) jobs. The LB function divides the traffic-flow demands between the end devices to avoid links congestion. In short, SDN is proposed to manage more operative configurations, efficient enhancements and further elasticity to handle massive network schemes. In this paper the opendaylight controller (ODL-CO) with new version OF 1.4 protocol and the ant colony optimization algorithm is proposed to test the performance of the LB function using IPv6 in a SDN-DC network by studying the throughput, data transfer, bandwidth and average delay performance of the networking parameters before and after use of the LB algorithm. As a result, after applying the LB, the throughput, data transfer and bandwidth performance increased, while the average delay decreased.

Genetic algorithm (GA) is a part of evolutionary computing that simulates the theory of evolution and natural selection, where this technique depends on a heuristic random search. This algorithm reflects the operation of natural selection, where the fittest individuals are chosen for reproduction so that they produce offspring of the next generation. This paper proposes a method to improve GA using artificial bee colony (GABC). This proposed algorithm was applied to random number generation (RNG), and travelling salesman problem (TSP). The proposed method used to generate initial populations for GA rather than the random generation that used in traditional GA. The results of testing on RNG show that the proposed GABC was better than traditional GA in the mean iteration and the execution time. The results of testing TSP show the superiority of GABC on the traditional GA. The superiority of the GABC is clear in terms of the percentage of error rate, the average length route, and obtaining the shortest route. The programming language Python3 was used in programming the proposed methods.

Among the crucial invention of the 5G is the device to device (D2D) system, whereby cellular gadgets correspond via immediate transfer or by multihop transfer excluding the ground-terminal. It is probable that D2D users are concurrent with human body network. Due to this, we suggested an internet of health things (IoHT) system which enables collaboration work among D2D users and human body indicators. We may regard the power as the most unique source in the wireless body area network (WBAN). The least needed transferring capacity may accomplish a particular degree of function, and minimum capacity for transfer holds a crucial responsibility in decreasing power usage. In this study, we discovered the needed transfer energy of four transferring modes: the straight transferring system, the double-hop transferring system, as well as double increasing coordinated transferring system with Rayleigh medium vanishing in its layout. Besides that, we suggested an energy-competent system named as efficient-power transmission mode selection-based (EPTMS) system. The suggested system chooses suitable transferring system whereby it offers the least needed transferring energy that assures a particular transfer duration. The statistical as well as simulation results shows that the two-master node cooperative protocols (TMNCP), EPTMS may enhance system conduction within the main criteria.

This article introduces a planar monopole patch antenna for global positioning system (GPS) application. Our design has a circular patch with a stub of inverted L-shape which is used as the radiating portion and partial ground. Our proposed design of the stub allows the antenna to operate at a frequency of 1.5 GHz. The circular monopole is fed by an offset feeding to have an impedance match of 50 ohms. The compact antenna has been designed and simulated on RT Duroid 6006 material with relative permittivity ( ) of 6.15 and 0.0019 as the loss tangent. Our antenna has a dimension of 65 × 55 × 2.54 mm3 . A gain of 1.23 dB is observed at the resonant frequency of 1.5 GHz and the antenna exhibits dipole like radiation pattern both in E and H-plane. The antenna has better impedance matching, good gain and steady characteristics of radiation pattern across the operating bandwidth. High frequency structure simulator (HFSS) v.13.0 is used to carry out all the simulations.

One success factor of an online affiliate is determined by the quality of the content source. Therefore, affiliate marketplaces need to do an objective assessment to retrieve content data that will be used to choose the right product in the appropriate product filter. Usually, the selection is not made using a good and measured system so that the selection of product content is only based on parts that are not in accordance with what is seen or subjective. However, if analyzed using a good and measurable system will produce an objective product content and can have a positive impact on users because the selection is based on factual data. The purpose of this research is to analyze the potential of the affiliate marketplace by combining cosine similarity with vision-based page segmentation. This is a new breakthrough made for optimization to get the best content in accordance with the required criteria. This work will produce a number of product recommendations that are appropriate for publication and then made use of for comparison that matches the required criteria. At the limited evaluation stage, the performance of the proposed model obtained satisfactory results, in which 5 queries tested were all as expected.

To increase bandwidth and number of channels per fiber for more than one wavelength in the same fiber the dense wavelength division multiplexing (DWDM) technology has been utilized. One of the devices that are important in DWDM is an optical interleaver. This paper discussed the effects of temperatures in the DWDM interleaver by using the Mach-Zehnder interferometer (MZI) structures which is arranged in two-stage cascaded MZI and the three-stage cascaded MZI geometries. The main consequences of increase temperature inside the fiber optics are the change of effective refractive index in the material of silica fiber due to the thermo-optics effects. In our analysis we have used the transfer matrix method to investigate the wavelength dependence of output power to the temperatures changes that varies from 30oC to 430ºC. In the calculation we have used the C-Band range wavelength which is around 1530 to 1565 nm. It has been shown that the change of temperatures may shift the wavelength inside the MZI output power in linear manners. These effects may be used to tune wavelength transmission inside the MZI structures to suit the ITU-T defined grid.
