In this study, two 6D hyper-chaotic systems with integer and fractional orders in the presence of external disturbance and bounded parametric uncertainty with unknown bounds with two control signals are synchronised using an adaptive-sliding mode controller. In the definition of fractional order differentiation, Riemann-Louiville definition is used. To this end, the sliding surface and proper active feedback control law area determined and proper estimation laws are proposed for estimating unknown uncertainty bounds and the disturbance. The stability of the closed-loop control system is proved using the Lyapunov theorem. Simulation results in MATLAB demonstrate the desired efficiency of this method in the presence of disturbance and parametric uncertainty.

MapReduce is a distributed computing model for cloud computing to process massive data. It simplifies the writing of distributed parallel programs. For the fault-tolerant technology in the MapReduce programming model, tasks may be allocated to nodes with low reliability. It causes the task to be reexecuted, wasting time and resources. This paper proposes a reliability task scheduling strategy with a failure recovery mechanism, evaluates the trustworthiness of resource nodes in the cloud environment and builds a trustworthiness model. By using the simulation platform CloudSim, the stability of the task scheduling algorithm and scheduling model are verified in this paper.

Trust in online environments is based on beliefs in the trustworthiness of a trustee, which is composed of three distinct dimensions - integrity, ability, and benevolence. Zimbabwe has slowly adopted Internet of Things for smart agriculture as a way of improving on food security in the country, though there is hesitancy by most farmers citing trust issues as monitoring of crops, animals and farm equipment’s would be done online through connecting several devices and accessing data. Farmers are facing difficulties in trusting that the said technology has the ability to perform as expected in a specific situation or to complete a required task, i.e. if the technology will work consistently and reliably in monitoring the environment, nutrients, temperatures and equipment status. The integrity of the collected data as it will be used for decision making. There is a growing need to determine how trust in the technology influence the adoption of IoT for smart agriculture in Zimbabwe. The mixed methodology was used to gather data from 50 A2 model farmers randomly sampled in Zimbabwe. The findings revealed that McKnight etal. trust in technology model can be used to influence the adoption of IoT through trusting that the technology will be reliable and will operate as expected.Additional constructs such as security and distrust of technology can be used as reference for future research.

Schemata for concurrent processes sharing some resources first appeared for manufacture processes in works of family research duet Frank and Lillian Gilbreth in 1921. Flow chart standard, developed in 1947 by Herman Goldstine and John von Neumann, did not contain blocks for parallel processing of information. Program schemata, including concurrent programs, was developed in Novosibirsk, Russia, during 1950–1960 that includes program schemes of Yanov, Martiniuk, Ershov, and Lavrov for formal proof of (concurrent) program correctness andmaximising their efficiency. Place-transition nets, which were introduced in doctoral dissertation of Carl Petri in 1962 represent, in essence, a unification of the mentioned approaches having only two types of nodes in a directed bipartite graph; a crucial amendment of Carl Petri was the introduction of a dynamical process on the graphwith tokens situated inside places which were produced and consumed as a result of transitions firing. An attractionof Petri netswas apossibility of applying formal techniquesof analysis developed in 1970–1980by Hack, Molloy, TadaoMurata and others. Nets were widely applied for modelling concurrent programs, manufacturing and transportation systems etc. Concurrent programming languages appeared which were loading elements of Petri net graph by constructs of convectional programming languages. According to the Carl Petri firing rule, a single transition fires at a step chosen in nondeterminiatic way among the set of firable transitions. It was a brilliant abstraction to study behaviour of concurrent systems with regard to ALL permitted possibilities that was especially useful for verification of communication protocols. Concurrent (parallel) programming gains speed-up at the expense of doing a few actions simultaneously that becomes the basic motivation of introducing in 1990 the Anjey Salvitsky firing rule published in works of Hans-Dieter Burkhard. It was also called the maximal firing strategy and transformed the net into a Turing-complete system.

ABSTRACT Heterogeneous hardware other than a small-core central processing unit (CPU) is increasingly being used, such as a graphics processing unit (GPU), field-programmable gate array (FPGA) or many-core CPU. However, to use heterogeneous hardware, programmers must have sufficient technical skills to utilise OpenMP, CUDA, and OpenCL. On the basis of this, we previously proposed environment-adaptive software that enables automatic conversion, configuration, and high performance operation of once-written code, in accordance with the hardware to be placed. However, the source language for offloading was mainly C/C++ language applications, and there was no research into common offloading for various language applications. In this paper, for a new challenge, we study a common method for automatically offloading various language applications in not only C language but also Python and Java. We evaluate the effectiveness of the proposed method in multiple applications of various languages. GRAPHICAL ABSTRACT

This paper reviews memristive PUFs (Physical Unclonable Functions) reported in the literature. The paper explains the motivation for using memristor technology for implementing PUFs. It focuses on PUFs’ applications, sizes, analysis, and physical variations. In addition, the paper presents the number of samples generated using Monte Carlo simulation for evaluating the PUF circuits. This paper also describes the protocols, functionality, and methodologies proposed in the memristive PUF literature. Although memristive PUFs are not commercialized yet, there is a high expectation of exploiting the memristors as fundamental elements in the next generation of hardware security primitives (e.g. PUF) due to their unique characteristics such as forming process, temporal drift, nonlinearity, bidirectionality, nonvolatility and model complexity. There have been some survey papers on memristor PUFs in the past, however, the field has continued to develop so a comprehensive survey including recent publications seemed in order at this time. Lately, memristor technology improvement has accelerated, therefore creating a need for an updated survey of the applications of memristors for PUFs. GRAPHICAL ABSTRACT

High operating temperatures have been a major problem in embedded systems due to high throughput and compact designs required by modern applications. This paper introduces a novel strategy to subdue these high peak temperatures of MPSoC systems by incorporating task migration and task swapping, to eliminate hot spots and thermal gradients. The work further confirms that the proposed techniques help mitigate power consumption while maintaining a high throughput to satisfy the deadline requirements of the tasks in the system. A heuristic approach is presented that helps mitigate the hot spots and gradients specifically formed from the high-frequency execution of high-priority tasks. In addition, energy-aware task migration reduced the energy consumption in the system. Extensive experimental testing on actual hardware and simulation showed very plausible results to confirm the capability of the presented techniques to reduce peak temperatures along with reduced energy consumption in the system. The presented techniques performed better than many other standard and state-of-the-art published approaches in the literature. GRAPHICAL ABSTRACT

Existing algorithms for identifying clients on a network segment are based on static client binding by MAC address. MAC address generation is based on pseudo-random sequences of 0–256 characters. With this feature in mind, software was developed based on an algorithm for generating MAC addresses using bidirectional neural networks, followed by integration of a decision support system module. A secondary feature of the developed software is the ability to set a MAC validity timeout, which will limit access to the network segment and increase the security factor.

The H-structure connectivity of G is the cardinality of a minimum set of subgraphs in G, whose deletion disconnects G and every element in the set is isomorphic to H. Similarly, the H-substructure connectivity of G is the cardinality of a minimum set of subgraphs in G, whose deletion disconnects G and every element in the set is isomorphic to a connected subgraph of H.
