INTRODUCTION To design and validate a simulator for learning and training in the capsulorhexis technique. METHODS The system consists of a methacrylate support inclined 15° for the surgeon's hand, an area of commercially available aluminum foil, and another one of similar characteristics, where the student performs the technique through some slots that are previously made in the support. In o...

The process industries (chemicals, food, oil, ...) are characterized by continuous or batch -processes of material transformation. The design of such processes, and their mapping to the available equipment (plants composed of production units in which reactions take place), is a complex process that determines the competitiveness of these industries, as well as their environmental impact. In co...

Fish farmers manage assets of considerable value on a daily basis. Many aspects of the daily operation are automated in some way, such as the feeding system. Sensory equipment steadily becomes cheaper and more ubiquitous, yielding data that can be used by automated systems and for post-processing (i.e. data mining) to discover hidden trends in the data. However, a lot of information is only kno...

Interlocking tables are the functional specification defining the routes, on which the passage of the train is allowed. Associated with the route, the states and actions of all related signalling equipment are also specified. This paper formally models the interlocking tables using Coloured Petri Nets (CPN). The CPN model comprises two parts: Signaling Layout and Interlocking Control. The Signa...

A real-time hardware-in-the-loop tool set is presented to test automotive chassis controllers. The use of highspeed computers, specialized hardware interfaces, and instrumentation, as well as simulation models and automation software, provide a realistic and repeatable laboratory environment to supplement in-vehicle testing. In this paper, the dynamics for a variety of chassis models are presen...

In this paper, we propose a resource allocation and Tx power control scheme, called resource allocation and power control (RAPC) in an LTE-Advanced device-to-device (D2D) network. In the proposed scheme, the macro base station (mBS) and D2D senders (D2DSs) service macro user equipment (mUEs) and D2D receivers (D2DRs) use the different frequency bands and Tx power chosen as D2D links’ locations ...

Injuries involving the head and neck represent a significant proportion of sportsrelated trauma incurred by youth athletes. Approximately 6.5 % of over 2.6 million children ≤ 19 years treated for sport and recreation-related injuries in an emergency department setting between 2001 and 2009 had sustained traumatic brain injuries or concussions [1]. In this chapter, we will review the history of ...

"In an age of electronic banking and online college degrees, why hasn't the rest of the nation gone to voting on touchscreen computers? The reason is simple and resonates with the contentious debate that has yet to be resolved after at least 15 years of wrangling over the issue of electronic voting. No one has yet figured out a straightforward method of ensuring that one of the most revered dem...

The state and transformation of solid municipal waste management in Russia are considered against the background economic social changes associated with current coronavirus pandemic. Increasing volume changing structure MSW these conditions does not cancel, but increases relevance separate collection. It is shown that there insufficient funds for subsidizing regions (on example Republic Khakass...
