Value proposition analysis for solid state lighting: A case study of Ahmedali Ahmed Electrical Contracting; Marketing the product in the Kingdom of Bahrain
Get PDFThe proposition given to a product or service in terms of its worth given by a customer is researched and analysed to find the underlying factors contributing to the value. The study is undertaken to investigate the different factors that lays ground for increased ‘Customer value’ and ‘Product Value’. The research objective is to find the “Value Proposition Analysis for Solid State Lighting: a Case Study AhmedAli Ahmed Electrical Contracting; Marketing the product in the Kingdom of Bahrain” Most businesses generate profits, when the customers give a certain value(s) to the service/product provided by the business entity. This could involve many attributes to consider. The project overlooks in to this value significantly to understand the attributes that collectively contributes to ‘Valued Relation’ between the customer and the business. This is achieved by making effective use of literature suggested by various authors and by employing research strategies to validate the literature through the findings. The research also looks in to the case study organisation to fully understand the capabilities of the company to market the product. Thus, this analysis will be specifically looking in to the value proposition given to Solid State Lighting by the current UK customers and by clients of AhamedAli Ahmed Electrical Contracting, Kingdom of Bahrain. However, this analysis must viewed critically, as the product comes at a premium price and the study will be much centred in the Kingdom of Bahrain and cannot be generalised for the other GCC countries or the Middle East. This study is focused to generate strategies in marketing Solid State Lighting in Bahrain taking A.A.E as the Case Study Organisation understanding the Value Proposition for Solid State Lighting
DETERMINATION OF INFLUENCE OF THE PARAMETERS CONNECTED WITH THE STABILIZATION OF THE POSITION ON THE 5-AXIS MANIPULATORS’ OPERATION ACCURACY
No full textThe 5-axis systems, especially those that use in their kinematic chain both prismatic joints and revolute kinematic pairs are gaining popularity in many scientific disciplines with manufacturing, metrology and robotics at the forefront. This is therefore important to undertake research aiming in identification of sources
of inaccuracies in their functioning and investigation on possibility of eliminating or compensating them.
A significant impact on 5-axis kinematic structures accuracy may be assigned to parameters associated with
the stabilization of the machine position and angular position, such as position stabilization time, position overshoot and drift of positioning accuracy. These parameters are well described in ISO 9283 standard related to performance criteria and test methods for industrial robots. The methodology presented in this standard is adapted for testing the impact of mentioned parameters for functioning of 5-axis kinematic structures other than industrial robots, which mainly include five-axis coordinate measuring systems and machine tools. A series
of experiments performed on five-axis coordinate measuring system is presented in this paper, their results are assessed in a quantitative manner and basing on them a general algorithm for assessing the significance
of impact of position stabilization parameters on functioning of the manipulator is proposed.

Method for Accuracy Assessment of the Length Measurement Unit of Laser Tracking Systems
Get PDFLaser tracking systems are widely used in large-scale metrology of geometric quantities. Their importance is confirmed by the fact that one of the parts of the ISO 10360 series of standards has been devoted to the issue of assessing their accuracy (ISO 10360-10). A laser tracker is a device whose final measurement result is calculated using indications from various subsystems included in it, such as devices for measuring length and angle. The analysis of these individual impacts can be useful in creating simulation models of accuracy which, in regard to the Industry 4.0 concept, seem to be the most justified in terms of speed of operation and ease of use. For this reason, it may be particularly important to undertake research on the accuracy of this component in isolation from other factors affecting the measurement of the coordinates of the point. The article describes a method that allows separation of the length measurement error from the other components. The method uses a high-accuracy interferometer which is treated as a reference system that allows for the comparison of indications obtained using the tested distance measurement system. Thanks to the proposed method, it is possible to minimize errors from the optical system and other measuring systems. The use of a precise linear guide allows the reduction of errors related to the implementation of linear motion. The article presents the test method and the results obtained from performed experiments, as well as formulates conclusions and the directions of further development

Get PDFIndustry 4.0 represents a new paradigm which creates new requirements in the area of manufacturing and manufacturing metrology such as to reduce the cost of product, flexibility, mass customization, quality of product, high level of digitalization, optimization, etc., all of which contribute to smart manufacturing and smart metrology systems. This paper presents a developed inspection planning system based on CMM as support of the smart metrology within Industry 4.0 or manufacturing metrology 4.0 (MM4.0). The system is based on the application of three AI techniques such as engineering ontology (EO), GA and ants colony optimization (ACO). The developed system consists of: the ontological knowledge base; the mathematical model for generating strategy of initial MP; the model of analysis and optimization of workpiece setups and probe configuration; the path simulation model in MatLab, PTC Creo and STEP-NC Machine software, and the model of optimization MP by applying ACO. The advantage of the model is its suitability for monitoring of the measurement process and digitalization of the measurement process planning, simulation carried out and measurement verification based on CMM, reduction of the preparatory measurement time as early as in the inspection planning phase and minimizing human involvement or human errors through intelligent planning, which directly influences increased production efficiency, competitiveness, and productivity of enterprises. The measuring experiment was performed using a machined prismatic workpiece (PW)
Development of DYNAMIX Policy Mixes - Deliverable 4.2, revised version, of the DYNAMIX project
Get PDFThis report documents the development of the initial dynamic policy mixes that were developed for assessment in the DYNAMIX project. The policy mixes were designed within three different policy areas: overarching policy, land-use and food, and metals and other materials. The policy areas were selected to address absolute decoupling in general and, specifically, the DYNAMIX targets related to the use of virgin metals, the use of arable land and freshwater, the input of the nutrients nitrogen and phosphorus, and emissions of greenhouse gases.
Each policy mix was developed within a separate author team, using a common methodological framework that utilize previous findings in the project. Specific drivers and barriers for resource use and resource efficiency are discussed in each policy area. Specific policy objectives and targets are also discussed before the actual policy mix is presented. Each policy mix includes a set of key instruments, which can be embedded in a wider set of supporting and complementary policy instruments. All key instruments are described in the report through responses to a set of predefined questions.
The overarching mix includes a broad variety of key instruments. The land-use policy mix emphasizes five instruments to improve food production through, for example, revisions of already existing policy documents. It also includes three instruments to influence the food consumption and food waste. The policy mix on metals and other materials primarily aims at reducing the use of virgin metals through increased recycling, increased material efficiency and environmentally justified material substitution. To avoid simply shifting of burdens, it includes several instruments of an overarching character
