Learning FPGAs : digital design for beginners with Mojo and Lucid HDL
\"Learn how to design digital circuits with FPGAs (field-programmable gate arrays), the devices that reconfigure themselves to become the very hardware circuits you set out to program. With this practical guide, author Justin Rajewski shows you hands-on how to create FPGA projects, whether you're a programmer, engineer, product designer, or maker. You'll quickly go from the basics to designing your own processor. Designing digital circuits used to be a long and costly endeavor that only big companies could pursue. FPGAs make the process much easier, and now they're affordable enough even for hobbyists. If you're familiar with electricity and basic electrical components, this book starts simply and progresses through increasingly complex projects\"--Publisher's description.

Assessment of the Ergonomic Quality of Hand-Held Tools and Computer Input Devices
The International Ergonomics Association (IEA) is currently developing standards for Ergonomic Quality in Design (EQUID) which primarily intends to promote ergonomics principles and the adaptation of a process approach for the development of products, work systems and services. It is important to assess the ergonomic quality of products, hand-held tools and computer input devices through working processes that represent reality. Well-designed working tools can be expected to reduce or eliminate fatigue, discomfort, accidents and health problems and they can lead to improvements in productivity and quality. Furthermore, absenteeism, job turnover and training costs can positively be influenced by the working tools and the environment. Not all these short-term and long-term issues of working tools can be quantified in pragmatically oriented ergonomic research approaches. But multi-channel electromyography, which enables the measurement of the physiological costs of the muscles involved in handling tools during standardized working tests, and subjective assessments of experienced subjects enable a reliable insight in the essential ergonomic criteria of working tools and products. In this respect it is advantageous to provide a test procedure, in which working tests can be carried out alternating both with test objects and reference models.

Sintered Diamond Tools – the Past, Present and Future
The methods of making diamond tools have undergone a remarkable development since the invention of synthetic diamond in the mid-1950s. The current review summarises key historical, recent and ongoing trends and developments in sintered diamond tools. The report concentrates on tools used within the stone and construction industries which, being the main consumers of metal-bonded diamond tools fabricated by powder metallurgy (P/M) technology, have always fuelled advances in tool design and production technologies.

Modeling, design, and implementation of a servo press for metal-forming application
Servo presses have been very popular in engineering applications due to their flexibility, simplicity in construction, and easy control. Many press manufacturer and researchers have studied on servo presses by developing different prototypes. However, only a few models have been commercially available in the market. Servo crank presses can generate different types of motion in their design limitations. They can present wide range of solutions to manufacturers. In this study, a dynamic model is derived by Lagrange approach for a servo crank press machine tool. A load capacity of 50 tons and stroke capacity of 200 mm prototype is designed and manufactured. A new motor-reducer selection methodology is suggested for servo presses. Servo motor-reducer combination is selected. Dynamic model and simulation results are presented with the real system parameters. Experimental validations have been performed on the servo press prototype. System’s dynamic model is validated by the experimental results. High precision of the manufactured servo press is also shown.

Design of a High-Speed Rotary Ultrasonic Machining Machine Tool for Machining Microstructure of Brittle Materials
Aiming at the problems of low machining accuracy and more serious tool wear in the traditional diamond grinding machining (DGM) microstructure of hard and brittle materials, this paper proposes high-speed rotary ultrasonic machining (HRUM) technology and develops a HRUM machine tool. The hardware part of the machine tool mainly includes the spindle module, micro-motion system module, ultrasonic machining tank module, and data acquisition (DAQ) system module. The LabView-based controlled machining control system, including motion selection, initialization, coarse tool setting, constant force tool setting, control machining, and coordinate display module, is developed. Comparative experimental research of the HRUM and DGM of small holes in Al2O3 ceramics is carried out in the developed HRUM machine tool. The results demonstrate that HRUM effectively reduces axial cutting forces, reduces binder adhesion, and suppresses slippage while improving tool-cutting ability and extending tool life compared to DGM under the same machining parameters. This technology has essential research significance for the high-precision and efficient machining of microstructures in hard and brittle materials.

Engaging the Crowd: Lessons for Outreach and Tool Design From a Creative Online Participatory Study
In this article, the challenges of realising e-participatory projects in urban planning are described. A participatory case study in Singapore serves as the basis for their presented conclusions. The researchers used a map-based e-participation tool to collect design proposals from participants for the planning site. The user feedback for the tool interface and the study campaign's website together with designer expertise on user interfaces (UI) was incorporated into the redesign of the website and interface of the participatory design tool. From there, some general guidelines for conducting engagement studies and for designing participatory design tool interfaces for non-expert users were formulated. One key finding is that the information presented to the non-expert user must be concise, and the UI must be adapted to the user's habits and focus the user's attention towards completing the study.
