We analyze with four compartments a deterministic nonlinear mathematical model of typhoid fever transmission dynamics. Using the Lipchitz condition, we verified the existence and uniqueness of the model solutions to establish the validity of the model and derive the equilibria states of the model, i.e. disease-free equilibrium (DFE) and endemic equilibrium (EE). The computed basic reproductive number R0 was used to establish that the disease-free equilibrium is globally asymptotically stable when its numerical values are less than one while the endemic equilibrium is locally asymptotically stable when its values are greater than one. In addition, the Lyapunov function was applied to investigate the stability property for the (DFE). The model was numerically simulated to validate the results of the analysis.

The geometric difference in the relative arrangement of atoms in molecules with the same chemical formula significantly affects the properties of the crystal. For quantitative comparison of the spatial geometric structure of two molecules, we used the method of optimal superposition of molecules through the minimization of a certain comparison function by rotating the molecules after superposing their centers of mass. The search for the minimum of the comparison function over Euler rotation angles is performed by the Rosenbrock method. The assumed criterion for comparing molecules allows us to quantify the proximity in the spatial structure of molecules. The implementation of the method is shown by comparing the structure of eight molecules in four crystalline substances.

The paper presents a study of impasse (singular) points of autonomous quasi-linear constrained differential systems, also called differential-algebraic equations. The interest in such systems is motivated by their applications in various problems of pure and applied mathematics, including control theory, biology, and electric engineering. Local normal forms of such systems in a neighborhood of their impasse points are established.

The capability of transmission in Wireless sensor networks (WSN) is circumscribed due to the precincts in energy utilization, controlled resources of transmission devices and network components. Information compression is taken into account as the best option, because the major part of energy consumed is for transmission of information. Habitually Lossy compression is adopted, since WSN abides some error in the reconstructed signals subjected to some acceptable tolerance. Lasso based models have been ascertained their capability to effectually compress both multivariate and univariate data. Traditional Lasso considers l1-norm regularization for learning in multi-dimensional data sets and assumes sparsity as model parameters. Lasso prominence on sparsity and deal with the correlation between the data points. However, model sparsity may be constricting and not essentially the foremost applicable assumption in several problem domains. To eliminate this limitation, an enriched lasso (MLasso) is proposed for compression bearing in mind both sparsity and correlation. In specific the strategy can select data that are having strong features to reconstruct the data and are less correlated between each other. Furthermore, an efficient Alternating Direction Method of Multipliers (ADMM) is adopted to resolve the ensuing sparse non-convex optimization problem. Extensive experiments on diverse datasets provides the proof that MLasso outperforms other similar algorithms for signal compression. Thus the proposed method ensures less energy consumption, decreases power loss and improves the operational life and reliability of network components.

Hadoop is one of the most famous platform solutions for processing large volume and scale of data in parallel processing in Cloud computing. A Hadoop system can be characterized based on three main factors: cluster, workload and user. Each of these factors can be described as either heterogeneous or homogenous, which reflects the heterogeneity degree of the Hadoop systemThe objective of this proposed research work is to investigate the degree of influence of heterogeneity for each of these factors on the performance of Hadoop based on different schedulers. Three schedulers are considered with different levels of Hadoop heterogeneity and are tested and analyzed: the first algorithm considered is the FIFO (First in First out), the second is the Fair sharing, and the final is the COSHH (Classification and Optimization based Scheduler for Heterogeneous Hadoop). Performance issues are related to Hadoop schedulers and comparative performance analysis between different cases of jobs submission. These jobs are processed in different homogenous or heterogeneous data environments and under fixed or reconfigurable slot between map and reduce tasks for Hadoop MapReduce java programming clustering model. The results showed that when assigning tunable knob between map and reduce tasks under certain schedulers like FIFO algorithm, the performance enhanced significantly especially in cases of heterogeneity environment where the workload decreased significantly and the utilization of computational resources increase was obvious.

In this paper, the properties of coincidence points of mappings acting between $(q_1,q_2)$-quasimetric spaces are studied. For a pair of mappings, we obtain estimates for the distance from a point to the coincidence points set and intersection of the respective graphs of the mappings. In addition, the stability of coincidence points is studied. A generalization of Lim's lemma is obtained.

The concept of a universal device that can provide diagnostics and monitoring of individual and collective power supply systems, the construction of life support systems, the state of household appliances, the Internet of Things devices and housing and communal services devices is considered. This paper proposes new design solutions able to improve the existing technologies for assessment of the quality of the energy flow by two orders of magnitude in terms of overall characteristics relative to the existing analogues. The developed Smart microcontroller is designed to operate as an intelligent unit, to analyze the parameters of the AC voltage network and control the electromechanical elements of the Smart Circuit Breaker, as well as to send data through a standard interface. The implementation of protection against spark discharge is proposed. The proposed solution is based on the application of cloud and boundary computing technology. The possibilities for improvement of the efficiency of design technologies and construction of energy-efficient buildings, provision of the industry and households with a new type of information management services (monitoring energy infrastructure, etc.) are presented.

A mathematical framework based on category theory is proposed to formally describe and explore procedures of modeling engineering products and processes that comprise operation of a model-oriented enterprise. The framework is intended to provide interoperability across a variety of engineering modeling languages and tools, supplying them with a common abstract foundation capable to represent, generate, and verify diverse design and production knowledge. The framework is leveraged via algebraic representation of product configurations as diagrams in categories with models as objects and descriptions of actions involved into products assembly as morphisms. Relevance of the framework is justified by appealing to systems engineering standards such as IEC 81346. Category theoretical methods for solving direct assembly problems that consist in constructing a product model from a given configuration are presented. Specifically, solutions are obtained via the universal construction called a colimit of a diagram. Much attention is then paid to stating and solving inverse assembly problems that consist in recovery and subsequent optimization of the configuration from the product model and assembly actions. Inverse problem solving is in demand for generative design, viz. an emerging fully automatic product development and manufacturing technology. Example solutions to direct and inverse problems are described in categories that represent two major areas of model-based enterprise operation: solid body geometric modeling of mechanical products and discrete-event simulation of production processes.
