Road passenger transportation faces a global challenge of reducing environmental pollution and greenhouse gas emissions because of the vehicle weight increases needed to enhance passenger safety and comfort. This paper aims to present a preliminary mechanical design evaluation of the Wikispeed Car (with a focus on body bending, body torsion and body crash) to assess light-weighting implications and improve the vehicle’s environmental performance without compromising safety.

For this research, finite element analysis (FEA) was performed to examine the Wikispeed chassis for light-weighting opportunities in three key aspects of the vehicle’s design, namely, for body bending the rockers (or longitudinal tubes), for body torsion (again on the rockers but also the chassis as a whole) and for crash safety – on the frontal crash structure. A two-phase approach was adopted, namely, in phase one, a 3D CAD geometry was generated and in phase, two FEA was generated. The combination of analysis results was used to develop the virtual model using FEA tools, and the model was updated based on the correlation process.

The research revealed that changing the specified material Aluminium Alloy 6061-T651 to Magnesium EN-MB10020 allows vehicle mass to be reduced by an estimated 110 kg, thus producing a concomitant 10 per cent improvement in fuel economy. The initial results imply that the current beam design made from magnesium would perform worst during a crash as the force required to buckle the beam is the lowest (between 95.2 kN and 134 kN). Steel has the largest bandwidth of force required for buckling and also requires the largest force for buckling (between 317 kN and 540 kN).

This is the first study of its kind to compare and contrast between material substitution and its impact upon Wikispeed car safety and performance.

Quality management standards (e.g. ISO 9001) lead to process conformance in the realization of quality goods and services; however, they can be rather document intensive. This paper investigates documentation practices used for aligning “light-weight” Scrum methods with ISO 9001 in a leading healthcare software firm.

The authors investigated how “light-weight” Scrum approaches fit with organizational documentation practices for ISO 9001 compliance in one leading healthcare software development firm. Three investigative rounds were conducted with software professionals having different Scrum roles to understand their challenges in maintaining process documentation with Scrum methods.

ISO standards stipulate certain mandatory documentation as evidence that certain pre-defined processes are followed in the build-up of quality goods and services. However, this may result in “heavy-weight” document driven approaches that interfere with “light-weight” Scrum methods. Case study findings reveal tensions faced by software professionals in maintaining the ISO 9001 documentation. That is, while some level of documentation is considered useful, software professionals consider certain other documentation tasks to be excessive and cumbersome. Further, many operational documents were written retrospectively for administrative compliance, leading to reduced, incomplete and ambiguous descriptions.

The study provides much value for practitioners in adapting their documentation with ongoing operational processes. Further, the critique on current ISO 9001 implementations in Agile environments has implications for future documentation practice.

The empirically drawn findings showcase some of the challenges in maintaining ISO 9001 documentation within Scrum projects. The study has contributed to both theory and practice in relation to the co-existence of ISO drawn standards with Agile approaches used for software development.

The global performance of industrial robots partly depends on the properties of drive system consisting of motor inertia, gearbox inertia, etc. This paper aims to deal with the problem of optimization of global dynamic performance for robotic drive system selected from available components.

Considering the performance specifications of drive system, an optimization model whose objective function is composed of working efficiency and natural frequency of robots is proposed. Meanwhile, constraints including the rated and peak torque of motor, lifetime of gearbox and light-weight were taken into account. Furthermore, the mapping relationship between discrete optimal design variables and component properties of drive system were presented. The optimization problem with mixed integer variables was solved by a mixed integer-laplace crossover power mutation algorithm.

The optimization results show that our optimization model and methods are applicable, and the performances are also greatly promoted without sacrificing any constraints of drive system. Besides, the model fits the overall performance well with respect to light-weight ratio, safety, cost reduction and others.

The proposed drive system optimization method has been used for a 4-DOF palletizing robot, which has been largely manufactured in a factory.

This paper focuses on how the simulation-based optimization can be used for the purpose of generating trade-offs between cost, performance and lifetime when designing robotic drive system. An applicable optimization model and method are proposed to handle the dynamic performance optimization problem of a drive system for industrial robot.

Human care and service demands will need innovative robotic solutions to make the day‐to‐day life of elderly and disabled people in home and workplace environments easier. The main objective of this work is to develop a new concept of climbing robot for this type of service applications.

ASIBOT is a 5 DOF self‐containing manipulator that includes the entire control system on‐board. The main advantage of this robot is its light weight, about 11 kg with 1.3 m reach. The robot is totally autonomous and only needs a power supply to be operated.

The robot is an arm able to move between different points (Docking stations (DS)) of the rooms and, if necessary, “jump” to (or from) the environment to the wheelchair. In this way the ASIBOT robot could become a home companion and assistance for numerous people.

The casts sector is an important sector for orthopaedic textile products. Plaster and plastics casts are widely used in hospitals, pharmacies and health care centers, but they are heavy, not washable and do not offer a suitable fixation for bone fractures (e.g. hand wrist), especially when operated under different swelling conditions. After decreasing of the swelling, the cast is in a hard form and the stabilization effect of the cast is insufficient due to the occurring of distance between the skin and the cast. The purpose of this paper is to develop a new pneumatic cast that depends on Polyvinylchlorid coated fabric as an outer layer, skin friendly internal layers, an air chamber, and metal braces.

For more comfort, the cast is anatomically formed and the internal layers are made of cotton‐viscose fabrics and Polyester spacer fabrics. The pressure on the injured part can be controlled by using a pneumatic structure.

The characteristics of the developed pneumatic cast are found to be: easy to use, comfortable, washable, and light weight.

The paper describes the development of a new pneumatic cast that can overcome the difficulties of cast fixation with the injured part of the body: an economic product, that should be easy to use, light weight, comfortable, skin friendly, water resistant, easy to clean, and affordable.

THE light‐weight air compressors of the single‐stage, single or double cylinder type manufactured by The British Thomson‐Houston Co., of Coventry, have rapidly gained favour from their excellent performance and hours of trouble‐free running on civil and Service aeroplanes.

The texturalcentric model of visual and tactile response to textural fabric surfaces was used to extract characteristics that could be used to build a construct definition of texture perception. Using multidimensional scaling analysis permitted subjects to provide numeric judgements of fabrics rather than using words with the individual's historic definition of those terms or without knowledge of some terms. Two hundred and forty subjects (50 per cent male, 50 per cent female) provided visual, tactile, or visual and tactile ratings of similarities of fabrics. The 47 fabrics were used in two administrations to ascertain cross‐validation. Data were analysed using M‐D SCAL Version 5M. Dimensions or characteristics of fabric were statistically analysed and named using bipolar adjectives: rough to smooth, plane to depth, irregular to regular surface units, shiny to matt, fine to coarse, light weight to heavy weight, simple to complex, small units to large units, open to compact, and soft to bumpy‐rough.

There had been many pieces of research on international expansion approaches, and they continued to grow. However, research about the firms belonging to emerging nations and that went global were still in the early stages. It had been argued that most theories on international expansion had focused on explaining the internationalization of large firms, majorly originating in developed countries. This case study offers an intriguing reading about an Indian MNC, successfully entering the developed markets and competing thereof amidst tough and complex world. Moreover, the leaders like Baba Kalyani met the stiff challenge from complexities and disruption successfully through entrepreneurial mindset. The case study offers insights into “Creating Value Through Entrepreneurial Leadership Framework”.

The case study has been developed through secondary data sources. The published online resources, the firm's annual reports formed the basis of the research work. Author accessed online news articles, auto component industry experts' views and reports from global consultancy firms, and auto industry body such as SIAM (Society of Indian Automobile Manufacturers) reports helped the research. The views and interviews by promoters of the company are available online for deeper insights and analysis.

An Indian multinational, Bharat Forge Limited (BFL), was a shining example of achieving global manufacturing standards through perseverance and entrepreneurial leadership. For more than the past four decades, BFL faced complexities, uncertainties and disruptions multiple times, and every time, the business world saw a resurgent company, Bharat Forge. The company achieved growth through diversification, related and unrelated, acquisition, product innovation, portfolio expansion and expansion in domestic and global development. Competitive market, economic slowdown, innovation and technology disruption had not deterred BFL from growing into a worldwide auto component giant. BFL overcame all hurdles with grit and enterprise. It achieved a paradigm shift with over half the revenue from non-automotive sectors such as defence, electric vehicle components, e-mobility, power electronics and aluminium light-weighting.

The conceptual framework pertaining to corporate strategy, global expansion, diversification, product development, innovation, disruption, market development and entrepreneurial leadership can be taught through the case. The case is suitable for MBA executive students as well, in courses mentioned above in addition to courses such as strategic leadership.

The aim of this paper is to make lightweight high-performance concrete (LWHPC) with high economic performance from existing materials on the Algerian market. Concrete with high values with regard to following properties: mechanical, physical, rheological and durability. Because of the implementation of some basic scientific principles on the technology of LWHPC, this study is part of the valuation of local materials to manufacture LWHPC with several enhanced features such as mechanical, physical chemical, rheological and durability in the first place and with regard to the economic aspect in the second place.

The experimental study focused on the compatibility of cement/superplasticizer, the effect of water/cement ratio (W/C 0.22, 0.25, 0.30), the effect of replacing a part of cement by silica fume (8 per cent), the effect of combined replacement of a part of cement by silica fume (8 per cent) and natural pozzolan (10 per cent, 15 per cent, 25 per cent) and the effect of fraction of aggregate on properties of fresh and hardened concrete using the mix design method of the University of Sherbrooke, which is easy to realize and gives good results.

The results obtained allow to conclude that it is possible to manufacture LWHPC with good mechanical and physical properties in the authors’ town with available materials on the Algerian market. The mix design and manufacture of concrete with a compressive strength at 28 days reaching 56 MPa or more than 72 MPa is now possible in Biskra (Algeria), and it must no longer be used only in the experimental field. The addition of silica fume in concrete showed good strength development between the ages of 7 and 28 days depending on the mix design; concrete containing 8 per cent silica fume with a W/B (water/binder) of 0.25 has a compressive strength higher than other concretes, and concrete with silica fume is stronger than concrete without silica fume, so we can have concrete with a compressive strength of 62 MPa for W/C of 0.25 without silica fume. Then, one can avoid the use of silica fume to a resistance of concrete to the compressive strength of 62 MPa and a slump of 21 cm, as silica fume is the most expensive ingredient in the composition of the concrete and is very important economically. A main factor in producing high-strength concrete above 72 MPa is to use less reactive natural pozzolan (such as silica fume) in combination with silica fume and a W/B low of 0.25 and 0.30. The combination of silica fume and natural pozzolan in mixtures resulted in a very dense microstructure and low porosity and produced an enhanced permeability of concrete of high strength, as with resistance to the penetration of aggressive agents; thus, an economical concrete was obtained using this combination.

The study of the influence of cementitious materials on concrete strength gain was carried out. Other features of LWHPC such as creep, cracking, shrinkage, resistance to sulphate attack, corrosion resistance, fire resistance and durability should be also studied, because there are cases where another feature is most important for the designer or owner than the compressive strength at 28 days. Further studies should include a range of variables to change mixtures significantly and determine defined applications of LWHPC to produce more efficient and economical concretes. It is important to gather information on LWHPC to push forward the formulation of characteristics for pozzolan concrete for the building industry.

The LWHPC can be used to obtain high modules of elasticity and high durability in special structures such as marine structures, superstructures, parking, areas for aircraft/airplane runways, bridges, tunnels and industrial buildings (nuclear power stations).

The novel finding of the paper is the use of crystallized slag aggregates and natural pozzolan aggregates to obtain LWHPC.
