“The most devastating disease to humanity is commonly known as elephantiasis. Infection usually acquired in childhood but visible indication like pain, disfiguring occur later in life. Severely affected people will have a permanent disability. Not only had it generated physical challenges it also cost for social, psychological, and economical losses. The impact of the disease is so painful and devastating among young men and women as they live with the lifelong disfiguring condition. As the parasite attacks directly to the lymphatic system of the body whose primary function is to drain all the harmful components and impurities from tissues and cells also make a strong immune system of the body to fight against infection and diseases. Since the parasite attack damages the lymphatic vessels and capillaries. Hence the effect is on the flow of lymph resulting in lymphoedema. 90% of the cas...

The implementation of any software development process involves the consumption of critical resources. Software engineers cannot experiment with different development processes before starting them in real projects, due to the time that would entail and the amount of elements that are involved, so it is vital to have tools that allow the pre-visualization of the results of executing the software development process and how the environmental variables affect it, thus being able to anticipate under what conditions the software development process will be deployed. This paper presents the modelling and simulation of a software development process using System Dynamics (SD), which allows the graphical representation of the elements intervening in the software process, and the incorporation of as many relevant elements as possible. As a software costs estimation reference, the COCOMO estimati...

We present a first approach to a new method to compute the motion estimation in digital videos using the two-dimensional instantaneous frequency information computed using amplitude-modulation frequency-modulation (AM-FM) methods. The optical flow vectors are computed using an iteratively reweighted norm for total variation (IRN-TV) algorithm. We compare the proposed method using synthetic videos versus a previous three-dimensional AM-FM based method and available motion estimation methods such as a phase-based, Horn-Schunck and the Lucas-Kanade methods. The results are promising producing a full density estimation with more accurate results than the other methods.

The emergence of Machine Learning (ML) technologies and their integration into agriculture has demonstrated a significant impact on disease detection in crops, enabling continuous monitoring and enhancing risk planning and management. This study applied image processing techniques such as thresholding, gamma correction, and the Stretched Neighborhood Effect Color to Grayscale (SNECG) method, alongside ML, to develop a predictive model for identifying five types of rice diseases. The ML techniques used included Logistic Regression, Multilayer Perceptron, Support Vector Machines, Decision Trees, and Random Forests (RF). Hyperparameters were optimized and evaluated through 5-fold cross-validation. In the results, the SNECG method successfully converted images to grayscale, capturing essential features of lesions on rice leaves. The ML models developed with these techniques showed evaluation...

The growth of cloud application services delivered through data centers with varying traffic demands unveils limitations of traditional load balancing methods. Aiming to attend evolving scenarios and improve the overall network performance, this paper proposes a load balancing method based on an Artificial Neural Network (ANN) in the context of Knowledge-Defined Networking (KDN). KDN seeks to leverage Artificial Intelligence (AI) techniques for the control and operation of computer networks. KDN extends Software-Defined Networking (SDN) with advanced telemetry and network analytics introducing a so-called Knowledge Plane. The ANN is capable of predicting the network performance according to traffic parameters paths. The method includes training the ANN model to choose the path with least load. The experimental results show that the performance of the KDN-based data center has been greatl...

In this work we critically approach the figure of the illicit association from a double perspective: historical and constitutional, questioning its theoretical foundations and its jurisprudential use. We connect your employment with arbitrary criminal proceedings where procedural guarantees are usually violated. We recover its political history in times of witch hunts, when the term „subversive association“ is born, in times of persecution of the coven, taken by many contemporary historians (especially feminist as Silvia Federici) as forms of resistance to new forms of organization of rural property (since behind the witch hunt was the expansion of rural capitalism) or resistance to the privatization of land in Europe. We conclude, making a parallel with the witch hunt (political criminalization program), that the alternative to the constant and growing criminalization of marginaliz...

Globally, a large amount of agri-food waste is generated as a result of industrial processes or direct consumption of raw materials, and when discarded, they represent a factor of environmental pollution. Mango by-products have a great bioactive potential, especially because they contain phenolic compounds in which mangiferin predominates, in addition to a great variety of phenolic acids, flavonoids and tannins, which confer antioxidant effects against cancer, cardiovascular and neurological diseases, among others. In addition, it was demonstrated that they have an effect against a broad microbial spectrum, including multiple pathogenic bacteria and fungi such as Escherichia coli and Candida albicans, respectively. According to the literature, mango peel and seed extracts also have potential as an additive, by influencing the sensory and physicochemical characteristics of foods, which ha...

The plant layout problem can be generalized as a case intensively studied combinatorial optimization and therefore its nature is a NP- hard. The core of the problem originally introduced as the Systematic Distribution Planning , a multi -criteria and relatively simple, has been extended to larger contexts , through the formulation as a mathematical model based on the nature of the workshops . Given the computational complexity of the calculations have been developed heuristics ,metaheuristics and others to obtain approximate solutions . The aim of this study is to analyze recent research on plant distribution problems within the industrial context by classifying and comparing the representation of the problem , solution methods , constraints and the objective function used . The report covers more than 30 peer-reviewed articles on the subject. Particular attention is placed on recent pub...

In this research a generalized inversion method was applied to obtain the epicenter of seismic events of local and regional origin from the readings of arrival time of P and S phases of at least 4 seismic stations. The initial condition of the model is obtained from the location of the seismic station closest to the epicenter, the initial origin time is obtained from the Wadati diagram and the initial depth is set up to 33 km for each case. We suppose a homogeneous velocity model of the P wave of 7.6 km/s (obtained from the inversion process). From the analysis of eigenvalues and eigenvectors of the system matrix (GTG), we deduce that the most stable parameter is the origin time and the most unstable parameter is the focal depth. The linearized model converges quickly to the solution.

This paper presents a noise reduction method for electrocardiographic (ECG) signals with real-time application. The method was evaluated using digitized signals with resolutions of 14, 16, and 24 bits, durations ranging from 30 to 60 seconds, and a sampling frequency of 1000 Hz. Prior to its application, power line interference (220V/60Hz) is attenuated if present. The approach is based on signal decomposition via the Stationary Wavelet Transform (SWT), analyzing 10 detail levels and 10 approximation levels. It was identified that noise is primarily concentrated in the first four levels, occasionally extending to the fifth. To differentiate between useful signal and noise, histograms of the detail coefficients were analyzed, and key metrics such as kurtosis, relative wavelet energy (RWE), and standard deviation were computed to establish adaptive thresholds for effective noise removal. T...

This research analyzes the distribution of a poultry plant, with defined processes and established areas. However, it has been proven that the poultry production process can optimize its processes by redistribu ting it, applying the SLP (Systematic Layout Plan- ning) methodology. In addition, the purpose is to take the process to a second level of improvement with process automation. Initially, the plant plans were analyzing in detail, these allowed us to visualize which areas should be improved. Then, the DAP (Process Activity Diagram) was analyzed, where the activities are identified for the plant process. Thereafter, the SLP method is applied, which is essential for the redistribution of the plant. Once a more ef ficient plant has been obtained, productivity is analyzed using a distance and load matrix. Furthermore, the idea of automation in important processes is shown in a cost and ...
