The selection of the delivery scheme is one of the most complicated problems and the results of its solution condition the sustainable development of the whole market of transportation services. Freight forwarders should consider numerous random parameters characterizing demand and technological processes to choose the proper structure of the logistics chain. The paper aims to propose a method for choosing the logistics chain structure, based on the analysis of the total expenses as a function from the demand parameters characterizing stochastic variables of the consignment weight, the delivery distance, and the time interval between the requests in the flow of queries for cargo delivery. Four basic logistics chain structures, widely used on road transport, are described to demonstrate the selection process. The areas of the most efficient use of the logistics chain structures can be defined for the flow of requests for cargo deliveries. The paper shows such areas on the example of goods delivery by automobile transport. Determining the areas of the most efficient use of the specific logistics chain structures contributes to the effective choice of correct delivery variants by freight forwarders.

The paper presents a comparative analysis of the technique of cutting materials such as water jet cutting and laser cutting. The tests were carried out while cutting plastic elements, such as: PMMA, HIPS and ABS. To compare the analysed cutting methods, it was necessary to limit the type of material to be cut to the selected plastics due to the limited thickness range of the samples cut with the use of the laser used for the tests. The workpiece was designed in AutoCAD. The geometry was designed in such a way that it was possible to compare the accuracy of cutting both straight sections, curves and holes using the cutting techniques tested. The roughness of the treated surfaces (edges of the samples) was also analysed. A roughness gauge was used to test the edges. The obtained research results were compiled and analysed to determine the optimal technology and parameters of cutting processes for individual types of selected materials and shapes. As it was shown, the wrong selection of the cutting technology in relation to the processed material or the wrong selection of machining parameters may lead to the destruction of the detail being made and incur significant costs.

The concepts which go out from the design activity are based on high knowledge [1], rules of designing [2] and previous experience. Until the product is closer to the series and after in the final customer environment, many processes have to be followed. In the development phase (the phase which contains the concept ideas), considering that a separate plastic connector assembled with Aluminum housing has more advantages [4], the current topic which is handled in this paper is to change the material to plastic and establish how the PCB is mounted and positioned inside the housing. More said which the optimal process for this application is. And this is the most challenging step, of choosing the optimal technology for the assembly (in this case 2 assemblies are considered: the PCB with the housing, which is the PCB mounting/ fixation, and the PCB holes with the connector pins, which is the PCB positioning). The material was changed due to higher properties of plastic which in automotive field brings strong added value. As known, in automotive field there are several processes for the mounting of PCB inside the housing like, snapping-on, clamping, screwing and press-fit. To position and to interconnect the PCB holes with the pins, processes like press-fit, spring contact and wave soldering. The selection of the proper process is made by implementing each of the processes requirements into the shape design of the connector, pins and housing.

Biohybrid microrobots, composed of a living organism integrated with an artificial carrier, offer great advantages for the miniaturization of devices with onboard actuation, sensing, and control functionalities and can perform multiple tasks, including manipulation, cargo delivery, and targeting, at nano- and microscales. Over the past decade, various microorganisms and artificial carriers have been integrated to develop unique biohybrid microrobots that can swim or crawl inside the body, in order to overcome the challenges encountered by the current cargo delivery systems. Here, we first focus on the locomotion mechanisms of microorganisms at the microscale, crucial criteria for the selection of biohybrid microrobot components, and the integration of the selected artificial and biological components using various physical and chemical techniques. We then critically review biohybrid microrobots that have been designed and used to perform specific tasks in vivo. Finally, we discuss key challenges, including fabrication efficiency, swarm manipulation, in vivo imaging, and immunogenicity, that should be overcome before biohybrid microrobots transition to clinical use.

This paper is devoted to the research and analysis of the applicability of geolocation technologies for the development of an application of a virtual museum of computer technology. It was necessary to select the optimal technology for use in the mobile application of the museum. During the research of the subject area, the requirements for the application were determined, on the basis of which the selection criteria for geolocation technology were formed. Next we made the review of existing geolocation technologies and identified the technology that most closely met the criteria. This article describes the subject area, it contains review of existing applications using geolocation technologies, selection criteria for the geolocation technology that are suitable for solving the problem, for analysis of the features of existing geolocation technologies, their comparison against generated criteria for selection of the most appropriate technology. In the technological part, the features of positioning technology based on BLE beacons are considered, and there are also the description of demo mobile application requesting exhibit data based on location of the user.

Abstract Decontamination is a major activity in decommissioning of Nuclear Power Plants. In efforts to reduce the overall volume of nuclear waste, retrieve reusable materials, and reduce the environmental impact, many different technologies have been developed/used in prior decommissioning projects and many more are being developed. However due to the amount of technologies available and the specific use cases for each, the ability to choose an appropriate and optimal technology is a challenge. An approach was adopted to develop a tool to assist in selection of decontamination technologies appropriate for Canadian Applications. The first step is the creation of a database to compile information of the different decontamination methods currently available in one location. The next step was the development of a software program to provide a search optimization for the database based on a set of initial user conditions. The program considers a radio-isotopic breakdown of a component as identified by the user and compares its concentration (Bq/g) to regulation limits set by the Canadian Nuclear Safety Commission (CSNC) for Unconditional Clearance Levels. Then, by using the CNSC guidelines, it will determine if the component is under Unconditional Levels or not. If the component is not, the code will calculate the minimum cumulative Decontamination Factor (DFR) required to make the component compliant with unconditional requirements. The software allows for users to plan their decontamination roadmap at a present state as well as a future state where natural decay opens up the ability for a wider range of decontamination technologies and for a combination of multiple components to use a given decontamination technique.
