AUTOMATED DEVICE PARTS TRANSPORTATION SYSTEM IN THE CONDITIONS OF MEDIUM-SERIES PRODUCTION

The article analyzes previous research and publications on the development and application of various types of automated transport carts used in serial production, from which a conclusion is drawn about the need to develop an automated transport cart that can be used in instrument manufacturing and which will increase the productivity of the transport system.
 After conducting the analysis, the main element of the automated transportation system was developed, which is an automated transport cart mounted on mecanum wheels, which ensure its all-directional movement, without changing the orientation in space or its change regardless of the direction of movement, with two on-board manipulators that have removable gripping devices, and an individual removable storage device. Changeable elements increase the flexibility of the automated cart, because this feature allows the cart to be adapted to a large number of various technological processes. With the help of the CAD system, a three-dimensional model of the schematic design of the automated transport cart was developed, which takes into account all its important elements, as well as a detailed model of the mecanum wheels, designed specifically for the design of the cart.
 Using the parameters of the developed automated transport cart, the kinematics of the cart were calculated and formulas for solving the forward and inverse kinematics problem were determined, as well as the algorithms of the cart operation were developed, which describe each cycle performed by the cart at each workplace. Based on formulas for solving kinematics problems, formulas and methods for leveling spatial errors that occur during movement from one point to another are defined, as well as functions for optimizing the process of moving an automated transport cart are defined, and how optimization affects performance is determined.

A layered Y(III)-viologen framework for efficient detection of nitrofurazone

Two-dimensional (2D) materials as sensors show the unique advantage in detection because of the functional sites on their surface are easier to contact with analytes. Based on the Hard-Soft-Acid-Base theory, a nitrogen-rich metal–organic framework, [Y3(ipbp)4(HCOO)4(H2O)2]·NO3∙8.5H2O (Y-MOF) was synthesized by solvothermal reactions of a viologen ligand bromide 1-(3,5-isophthalic acid)-4,4′-bipyridine (H2ipbpBr) and Y3+ ions. It shows a 2D layered structure in which these uncoordinated pyridine groups of ipbp− hang on both sides of the layer as Lewis basic sites and exhibits excellent chemical stability in aqueous solutions within a pH range from 1 to 13. Fluorescent experiment indicates that Y-MOF possesses a high sensitivity for nitrofurazone (NFZ) with a low detection limit of 0.77 ​μg/mL and a high quenching constant of 1.36 ​× ​104 ​M−1. The cycling tests confirm that this MOF can be easily recovered and repeatedly used without an obvious performance loss. Furthermore, Y-MOF can detect NFZ in irrigation water, river water, and milk, in which satisfactory recoveries ranged from 94.70% to 109.85% with low Removable Storage Device (RSD) of 0.55%–2.76%. These results demonstrate that Y-MOF can be used as a potential sensor for the practical detection of NFZ in water environment and food matrix.

Computer Virus Fractional Order Model with Effects of Internal and External Storage Media

In this work, we focus on the implementation of epidemic techniques on computer virus and study the dynamic transmission of several viruses to minimize the destruction of computers. We aim to make and analyze computer viruses through the Atangana-Baleanu sense and the Atangana-Taufik scheme, which is used for the fractional derivative model for the computer virusepidemic. It contained infected external computer effects and removable storage media on the computer viruses. For the validation of the model, we also discussed its positivity and boundedness. Fixed point theory and the iterative methods helped a lot to find out the existence and uniqueness of the model. In the case of numerical simulation, we used Atanagana-Taufik technique to illustratethe effects of varying the fractional order. The graphical results support our theoretical results from which, we analyze the infected external computer effects and removable storage media on the computer viruses.

Fractional Dynamics of Stuxnet Virus Propagation in Industrial Control Systems

The designed fractional order Stuxnet, the virus model, is analyzed to investigate the spread of the virus in the regime of isolated industrial networks environment by bridging the air-gap between the traditional and the critical control network infrastructures. Removable storage devices are commonly used to exploit the vulnerability of individual nodes, as well as the associated networks, by transferring data and viruses in the isolated industrial control system. A mathematical model of an arbitrary order system is constructed and analyzed numerically to depict the control mechanism. A local and global stability analysis of the system is performed on the equilibrium points derived for the value of α = 1. To understand the depth of fractional model behavior, numerical simulations are carried out for the distinct order of the fractional derivative system, and the results show that fractional order models provide rich dynamics by means of fast transient and super-slow evolution of the model’s steady-state behavior, which are seldom perceived in integer-order counterparts.

Modelling and Analysis of Propagation Behavior of Computer Viruses with Nonlinear Countermeasure Probability and Infected Removable Storage Media

The dissemination of countermeasures is diffusely recognized as one of the most valid strategies of containing computer virus diffusion. In order to better understand the impacts of countermeasure and removable storage media on viral spread, this paper addresses a dynamical model, which incorporates nonlinear countermeasure probability and infected removable storage media. Theoretical analysis reveals that the unique (viral) equilibrium of the model is globally asymptotically stable. This main result is also illustrated by some numerical experiments. Additionally, the numerical experiments of different countermeasure probabilities are conducted.

Analysis of computer virus propagation behaviors over complex networks: a case study of Oregon routing network

This paper mainly aims to explore the propagation behaviors of computer virus over complex networks under the combined effects of network topology and removable storage media. To this end, a dynamical model is established and analyzed theoretically, including the outbreak threshold, equilibria and their global dynamics. It is found from the systematic analysis that the virus will die out or persist in the network depending on the outbreak threshold, which is associated with the network topology and removable storage media. Moreover, a set of well-designed experiments are performed over the Oregon routing network to verify the proposed model and its theoretical analysis results. Experimental results show that the predicted results of the model are in good agreement with the simulation results over the above network, and the removable storage media have a great effect on viral spread. To this regard, some preventive measures against virus infection are recommended.

A delayed e-epidemic SLBS model for computer virus

We propose an e-epidemic time-delay Susceptible-Latent-Breaking out-Susceptible (SLBS) model to study delay dynamics appearing due to antivirus software, which takes time to clean the viruses from latent and breaking-out computers. We perform nonlinear stability analysis, Hopf bifurcation analysis, and its direction and stability. Numerical simulation results (time series analysis and bifurcation diagram) give useful insights for delay dynamics. We investigate the effect of the control parameters like rate of infection of all the classes and cure rates on the model system. Our results suggest that time delay is responsible for destabilizing the system dynamics. For smooth functionality of a computer system, our results suggest the minimum use of removable storage devices like smart phones, optical discs, memory cards, external hard disk, digital cameras, and so on and use of effective antivirus softwares.

Design of a mathematical model for the Stuxnet virus in a network of critical control infrastructure

The purpose of this study is to develop an epidemic virus model that portrays the spread of the Stuxnet virus in a critical control infrastructure after bridging the air-gap between a normal local area network and the critical network. Removable storage media plays an important role in the transfer of data and virus to the computers connected to the critical network (consisting of industrial controllers) and this can compromise the whole system. A mathematical model is formulated that incorporates these features and depicts the controlling mechanism. Disease free and endemic equilibria are analyzed in terms of the basic reproduction number R0. Global stability of disease free and endemic equilibrium points are analyzed using Lyapunov functions. Numerical simulations are performed to determine the accuracy of the proposed model for the smart Stuxnet virus which is designed to target critical industrial systems. Model shows very good resemblance with the observed real life data available for this virus. Future work may invoke interesting results and control strategies.

A software agent enabled biometric security algorithm for secure file access in consumer storage devices

In order to resist unauthorized access, consumer storage devices are typically protected using a low entropy password. However, storage devices are not fully protected against an adversary because the adversary can utilize an off-line dictionary attack to find the correct password and/or run an existing algorithm for resetting the existing password. In addition, a password protected device may also be stolen or misplaced allowing an adversary to easily retrieve all the stored confidential information from a removable storage device. In order to protect the consumer's confidential information that has been stored, this paper proposes a mutual authentication and key negotiation protocol that can be used to protect the confidential information in the device. The functionality of the protocol enables the storage device to be secure against relevant security attacks. A formal security analysis using Burrows-Abadi- Needham (BAN) logic is presented to verify the presented algorithm. In addition, a performance analysis of the proposed protocol reveals a significantly reduced communication overhead compared to the relevant literature.

Global Dynamics and Optimal Control of a Viral Infection Model with Generic Nonlinear Infection Rate

This paper is devoted to exploring the combined impact of a generic nonlinear infection rate and infected removable storage media on viral spread. For that purpose, a novel dynamical model with an external compartment is proposed, and the explanations of the main model assumptions (especially the generic nonlinear infection rate) are also examined. The existence and global stability of the unique equilibrium of the model are fully investigated, from which it can be seen that computer virus would persist. On this basis, a next-best approach to controlling the level of infected computers is suggested, and the theoretical analysis of optimal control of the model is also performed. Additionally, some numerical examples are given to illustrate the main results.

The effect of network topology on the spread of computer viruses: a modelling study

ABSTRACTThis paper is intended to investigate the effect of network topology on the spread of computer viruses in the presence of removable storage media. For that purpose, a novel network-based computer virus spreading model is proposed. Both theoretically and experimentally, it is shown that, under proper conditions, viruses on a scale-free network would tend to extinction. Experimental results show that either smaller maximum node degree or larger power-law exponent is conducive to the containment of virus spreading. To our knowledge, this is the first time the effect of network topology on virus spreading is investigated in this context.

Modeling the Spread of Computer Viruses under the Effects of Infected External Computers and Removable Storage Media

This paper is intended to investigate the effects of infected external computers and removable storage media on the spread of computer viruses. To this end, a new dynamical model, which has four compartments, is proposed. The analysis of the model shows that the unique equilibrium is globally asymptotically stable. This result is well suited for numerical implementation. An illustration of the influences of infected external computers and removable storage media is also included. Furthermore, it is found that (1) infected external computers and removable storage media can both accelerate the viral spread; (2) infected removable storage media can pose a greater threat than infected external computers.

A Novel Virus-Patch Dynamic Model.

The distributed patch dissemination strategies are a promising alternative to the conventional centralized patch dissemination strategies. This paper aims to establish a theoretical framework for evaluating the effectiveness of distributed patch dissemination mechanism. Assuming that the Internet offers P2P service for every pair of nodes on the network, a dynamic model capturing both the virus propagation mechanism and the distributed patch dissemination mechanism is proposed. This model takes into account the infected removable storage media and hence captures the interaction of patches with viruses better than the original SIPS model. Surprisingly, the proposed model exhibits much simpler dynamic properties than the original SIPS model. Specifically, our model admits only two potential (viral) equilibria and undergoes a fold bifurcation. The global stabilities of the two equilibria are determined. Consequently, the dynamical properties of the proposed model are fully understood. Furthermore, it is found that reducing the probability per unit time of disconnecting a node from the Internet benefits the containment of electronic viruses.

Theoretical and experimental analysis of the impacts of removable storage media and antivirus software on viral spread

In this paper, a new computer virus propagation model, which incorporates the effects of removable storage media and antivirus software, is proposed and analyzed. The global stability of the unique equilibrium of the model is independent of system parameters. Numerical simulations not only verify this result, but also illustrate the influences of removable storage media and antivirus software on viral spread. On this basis, some applicable measures for suppressing virus prevalence are suggested.

Propagation of computer virus under the influences of infected external computers and removable storage media

In reality, a portion of infected external computers could enter the Internet, and removable storage media could carry virus. To our knowledge, nearly all previous models describing the spread of computer virus ignore the combined impact of these two factors. In this paper, a new dynamical model is established based on these facts. A systematic analysis of the model is performed, and it is found that the unique (viral) equilibrium is globally asymptotically stable. Some simulation experiments are also made to justify the model. Finally, a result and some applicable measures for suppressing viral spread are suggested.
