As Stress

Abstract A novel intelligent experimental research environment (LUTERGO laboratory) for developing the usability of off-road machines was created at LUT University. The environment combines a real-time simulator and an experimental system for measuring human body responses when driving the virtual prototypes of machines. Based on the quantities measured from the operator, such as heart rate, electrodermal, muscular, and brain activity, the stress level of the operator can be evaluated. It is assumed that by combining simulated machine data and biosignals, the usability of every virtual prototype of a new machine can be assessed during the R&D process. This is an alternative to a traditional approach when usability is studied with physical prototypes after conceptual R&D phases using qualitative data from questionnaires. The paper describes the structure and capabilities of the LUTERGO laboratory. Results of the initial tests are presented, which studied the influence of hydraulic valve dynamics on excavator vibration and operator biosignals. The results show that the biosignal parameters used as stress indicators change following the variation of time constant for directional valves controlling the main boom cylinders of the excavator. The paper concludes with future research directions using the novel environment.

Different Characteristics

Broadly, the sustainable practices for the manufacturing supply chain are considered as environmental, social, and economic practices. But due to different characteristics of services, the above-mentioned sustainable practices are necessary. Beyond these practices, some other novel practices are necessary for the service context. This chapter discusses the novel sustainable practices for the service only supply chain (SOSC). The discussed sustainable practices will enhance the understanding of sustainable practices in SOSC context. How these practices will help the organizations in achieving sustainable development goals will also be discussed. Potential future research directions are also provided.

Functional Components

One-dimensional (1D) nanostructures are ideal systems for investigating the dependence of electrical transport, optical properties and mechanical properties on size and dimensionality. They are expected to play an important role as both interconnects and functional components in the fabrication of nanoscale electronic and optoelectronic devices. This article presents an overview of current research activities that center on nanowires whose lateral dimensions fall anywhere in the range of 1–200 nm. It is organized into three parts: The first part discusses various methods that have been developed for generating nanowires with tightly controlled dimensions, orientations, and well-defined properties. The second part highlights a number of strategies that are being developed for the hierarchical assembly of nanowire building blocks. The third part surveys some of the novel physical properties (e.g., optical, electrical, and mechanical) of these nanostructures. Finally, we conclude with some personal perspectives on the future research directions in this field.

And Control

Acupuncture, an ancient Chinese healing methodology, is becoming increasingly popular throughout the world. However, the mechanism by which acupuncture exerts its effects is not yet fully understood. Functional magnetic resonance imaging (fMRI) is a widely used technique to observe brain activity noninvasively. In this chapter, the authors first review the existing literature on the effects of acupuncture on brain activity and connectivity. The authors next discuss some basic issues in the study of acupuncture with fMRI, including deqi, baseline and control measures, acupuncture modalities, and experimental paradigms. At the end of the chapter, future research directions in the study of acupuncture with fMRI are suggested.

present, we are in the world of digital revolution. Use of smartphones and internet accelerated due to the impact of the novel Covid-19 virus. The whole world started to turn digital. The industrialization of Internet of Things (IoT) enables more devices to connect and communicate which leads to many data transfer transactions. The architecture of IoT is centralized. The distributed and decentralized architecture of Blockchain can be used to provide secure and scalable transactions of IoT devices. Blockchain is a distributed ledger technology, which provides secure data transactions that cannot be tampered and altered. In this paper, we provide advantages and challenges of integrating IoT and Blockchain. We also provide different architectures and algorithms proposed by researchers to provide secure data transactions.  We shall also shed light on the future research directions of integrating Blockchain and IoT.
