Electric wheelchairs make it easier for disabled and elderly people to live, move, interact, and participate in society. Moving a wheelchair in open spaces is relatively easy, but in closed and small spaces, maneuvering is difficult. Solutions to such problems for people with disabilities are applicable to a relatively small group of recipients and are mostly custom-made solutions, whose considerable cost is a significant barrier to accessibility. New technologies can provide an opportunity to improve the quality of life of people with disabilities in this aspect. Using selected elements of complex automation and control systems, cost-effective solutions can be created that facilitate the functioning of people with disabilities. This paper presents an analysis of hazards and problems when maneuvering a wheelchair in narrow passageways, as well as the authors’ solution to this problem, and the concept and assumptions of a mechatronic anti-collision system based on 2D LiDAR laser scanners. This solution is composed of a proprietary 2D rotating scanner mechanism that ensures the acquisition of 3D images of the environment around the wheelchair. Preliminary tests of this solution yielded promising results. Further research will include miniaturization of the device.

The sintering process involves a large number of parameters, more than 500, each of which exerts a greater or lesser influence and needs to be controlled, within the possible limits, in order to optimise productivity, process stability, and standardise the composition and quality of the sinter produced. To comply with environmental legislation, a pollution control system must monitor the particle matter and gases generated and emitted into the atmosphere by the sinter plant. Automation and control systems are vital tools to assist plant operators in the monitoring of each stage of the sinter production process.

AbstractNeglected tropical diseases (NTDs) are a diverse group of infectious conditions that vary in their epidemiology, impact and control. They are among the most common conditions globally, affecting approximately one billion people. Many NTDs have long-term consequences, such as visual and physical impairments. As a result, people with NTDs may have difficulties in carrying out activities or participating in society—in other words, NTDs can cause disabilities. Additionally, NTDs are often strongly linked to stigma and can have mental health consequences. It is therefore important to incorporate rehabilitation within NTD programmes. Rehabilitation can be conceptualized narrowly in terms of the provision of clinical services (e.g. physiotherapy and assistive devices) or, more broadly, including efforts to improve employment, overcome stigma and enhance social participation of people with disabilities. Approximately 15% of the global population has a disability, and this large group must be considered when designing NTD programmes. Improving the inclusion of people with disabilities may require adaptations to NTD programmes, such as making them physically accessible or training staff about disability awareness. Without incorporating disability within NTD programmes, the quality of life of people with NTDs will suffer and global targets for elimination and management of NTDs will not be met.

Future manufacturing is envisioned to be highly flexible and adaptable. New technologies for efficient engineering of reconfigurable systems and their adaptations are preconditions for this vision. Without such solutions, engineering adaptations of Industrial Process Measurement and Control Systems (IPMCS) will exceed the costs of engineered systems by far and the reuse of equipment will become inefficient. Especially the reconfiguration of control applications is not sufficiently solved by state-of-the-art technology. This chapter gives an overview of the use of reconfiguration applications for zero-downtime system reconfiguration of control applications on basis of the standard IEC 61499 which provides a reference model for distributed and reconfigurable control systems. A new approach for the reconfiguration of IEC 61499 based control application and the corresponding modeling is discussed. This new method significantly increases engineering efficiency and reuse in component-based IPMCS.

The requirements for the quality of aviation technology are decisive in the creation of technological systems that ensure the industrial purity of products. But the cost component of the finishing and stripping technologies is also important, the value of which depends on the chosen method of removing liquids, for example, from hydraulic units of aircraft. Reliable and cost-effective manufacture of parts with specific geometric and technological properties is the main goal of industrial production. In a market economy, the production of competitive products is a necessity, and it is always the choice of a rational, stable price-quality ratio. The quality of engineering products is a multifactorial problem, depending on the complex of systemic organizational and technological measures. In the production of aircraft technology, quality assurance is associated with dependability and a guaranteed resource that is vital due to specific operating conditions. One of the most important measures to ensure the reliability and guaranteed life of aviation products is to ensure industrial cleanliness. Cleaning from microparticles, macro- and micro-hauler surfaces and edges of parts after mechanical types of processing is included in the complex of these measures. The most problematic is the cleaning of body parts with a complex configuration of external and internal surfaces. The need to remove liquids and other technological pollution is explained by functional, ergonomic and aesthetic reasons. If ergonomic and aesthetic factors do not affect the technical characteristics of products, then the functional ones are directly related to the operability of machines and mechanisms. Functional causes are the prevention of failures of hydraulic distribution and control devices, as well as the prevention of increased wear of critical parts occurring when friction pairs of solid metal particles enter the gaps, difficulties in assembling and positioning, reducing fatigue strength and so on. Burrs cause turbulence in the flow of gas or liquid, disrupting the flow uniformity. It is obvious that the mutually influencing processes occurring in the hydraulic systems of machines, in violation of working conditions, lead to an increase in negative phenomena. The peculiarity of the use of purification technologies is the need to remove liquids from 100% of the parts included in the autonomous system of mechanisms. If at least one detail is left untreated, then the working fluid, when in contact with contaminated surfaces, washes away these contaminants and spreads them throughout the system, while the most sensitive elements are damaged. The reasons for the need to clean the surface and edges of parts from technological contamination are given. A brief review of the results of modeling and research on the removal of burrs in the environment of detonating gas mixtures has been performed. The features of the thermopulse process are considered and the results of numerical and experimental studies are presented. A comparative analysis of the energy intensity of removing burrs of various metals is shown.

Poor Working Condition

The construction industry is vital to the economic development of any country. It has a major role in providing built infrastructures in an innovative and cost-effective way using an effective procurement approach. In contrast, the most widely used procurement method in Nigeria is the traditional procurement approach which is known for plaguing the industry with the poor working condition and poor performances thus, reducing the sustainability and quality of products and services. For this reason, there is a need for a procurement approach which utilises expertise to minimise the risk of non-performance and create a win-win environment for both client and contractors, while increasing transparency and add value to the project such like, the Best Value Procurement. Against the background, this paper aims to establish the perception of the Nigerian construction professionals on the unique factors of the Best Value Procurement. The paper outlines the following objectives: To identify the unique factors of the Best Value Procurement and, to establish the perception of the Nigerian construction professionals on the Best Value Procurement unique factors. Using a questionnaire survey, data was collected form 314 construction professionals involving Quantity Surveyors, Architects, Builders and Civil Engineers. Kruskal Wallis Test and mean score ranking was used for data analysis. The findings show that the professionals generally agree that the Best Value Procurement unique factors can bring about transparency, accountability, increase project performance and the contractor is the best to control risk and adds value to the project. This paper derives its significance from the need to stabilise the procurement system in Nigeria by transferring the risk and control to contractors who must act in the best interest of the client.

Metals are a finite resource and their demand for use within existing and new technologies means metal scarcity is increasingly a global challenge. Conversely, there are areas containing such high levels of metal pollution that they are hazardous to life, and there is loss of material at every stage of the lifecycle of metals and their products. While traditional resource extraction methods are becoming less cost effective, due to a lowering quality of ore, industrial practices have begun turning to newer technologies to tap into metal resources currently locked up in contaminated land or lost in the extraction and manufacturing processes. One such technology uses biology for the remediation of metals, simultaneously extracting resources, decontaminating land, and reducing waste. Using biology for the identification and recovery of metals is considered a much ‘greener’ alternative to that of chemical methods, and this approach is about to undergo a renaissance thanks to synthetic biology. Synthetic biology couples molecular genetics with traditional engineering principles, incorporating a modular and standardised practice into the assembly of genetic parts. This has allowed the use of non-model organisms in place of the normal laboratory strains, as well as the adaption of environmentally sourced genetic material to standardised parts and practices. While synthetic biology is revolutionising the genetic capability of standard model organisms, there has been limited incursion into current practices for the biological recovery of metals from environmental sources. This mini-review will focus on some of the areas that have potential roles to play in these processes.
