Waste reduction in printing process by implementing a video inspection system as a human machine interface

Abstract Human mistakes are the main cause of most of the production failures and rejections for bad impressions in the printing industry, for this reason the industry has been working on the development and design of complementary equipment with the aim of reducing the rejections caused by these errors using human-centered design that allows focusing on reducing these mistakes, improving interaction and cooperation between the user, the machine and the process. Contextual research showed that there is currently qualitative evidence regarding the improvement of prints by having a machine video inspection system, but there is no quantitative analysis of the true cost-benefit that exists from having a video inspection and justify its implementation. Therefore this work defines a preliminary study of a video inspection system, used as a complementary equipment to a flexographic rotary printing machine, to improve the printing process focus on machine-human interaction, in a printing company of Mexico City after a notable need for an effective improvement in the printing process in order to reduce waste in production and in rejections for poorly printed jobs. Five representative jobs will be selected, and the cost per meter of linear printing will be evaluated, to give a value to the waste, later the decrease due to production and rejections of a run will be counted for each of the five selected jobs, with and without the system of video inspection, and finally with a comparative analysis of costs, the profitability of the equipment will be determined, obtaining as a result the viability of the equipment, which is directly related to the value of the decrease, since there is an equilibrium point between this value and the value of the equipment, where from there the implementation of the video inspection system is justified; due to the current situation of COVID 19, it was not possible to carry out the necessary measurements to validate the system. Therefore, only the proposed methodology will be described.

Numerical Simulation Platform for a Generic Aircraft Flight Dynamic Simulation

Flight simulation has been used for many purposes in several decades, started from pilot training, engineering purposes, even just for a hobby. In its development, computing technology has a vital role in aircraft simulation. Nowadays, people do an aircraft simulation mostly by using a set of the computing device and complementary equipment such as a joystick. On the other hand, engineers use aircraft simulation in order to evaluate the aircraft in many aspects such as flight performance, handling quality, and controllability. This paper proposes a simulation system to do an engineering simulation especially to evaluate controllability of an aircraft utilizing X-Plane 10, Python and MATLAB. This system can manipulate aircraft loading configuration and failure on aircraft systems, set the environment condition, and observe control-related flight parameters in MATLAB whilst the aircraft is still flying in the X-Plane 10 at the same time. The system had been tested and proved could work well with X-Plane 10. Â

Mechanical response of notched marble beams under bending versus acoustic emissions and electric activity

An experimental protocol, including the combined application of both innovative and traditional sensing techniques, is described aiming to explore the mechanical response of marble and also to check the possibilities of detecting precursor phenomena designating upcoming catastrophic fracture. The protocol consisted of three-point bending tests with notched prismatic beams made of Dionysos marble, the material extensively used for restoration of the Acropolis of Athens monuments. The sensing system improvised included techniques relying on completely different physical foundations, which permit simultaneous detection and recording of the Pressure Stimulated Currents, Acoustic Emissions, three dimensional displacement fields and Notch Mouth Opening Displacements. Analysis of the results revealed interesting features of the mechanical response of Dionysos marble and indicated, also, that classical Continuum Fracture Mechanics fails to describe accurately the response of marble, at least in the presence of notches. In addition, strong correlations between the Pressure Stimulated Currents, the rate of acoustic hits and the rate of change of the opening of the pre-existing notch have been enlightened. Moreover, the onset of catastrophic crack propagation appears following distinguishable changes of the Pressure Stimulated Currents recorded. Therefore (and taking into account the very small size of the respective sensors as well as the simple complementary equipment needed), it is concluded that the specific technique could be considered as a simple and reliable tool for an alternative approach to the in-situ Structural Health Monitoring of classical stone monuments.

Optimal configuration of power distribution networks with variable renewable energy resources

An attractive way to reduce losses in electric power distribution networks is addressing the network reconfiguration problem, which should give a topology for the primary distribution network that minimizes the total losses due to the electrical resistances in the lines and complementary equipment’s (technical losses). Distributed energy resources and additional innovations associated to smart grids allow enhancing the benefits of finding better network topologies. On the other hand, the integration of renewable energy sources with variable random outputs requires expanding the perspective in modeling the network reconfiguration problem and in the shaping of appropriate solution techniques. These issues are the object of this paper. The main new features of the problem are explored with a maquette designed to highlight the consequences of random generation sources in the networks. Following, the paper proposes a formulation for the problem that explicitly considers random energy sources. A state of the art genetic algorithm build under the biased random-key evolution framework (BRKGA) is developed to address this hard combinatorial optimization problem. Case studies with benchmark networks put into perspective the proposed methodology. Results show that random energy values should be explicitly modeled in contemporary approaches to the network reconfiguration problem. The paper provides the grounds for addressing this new problem and points to additional research paths in the area.

Condenser-free contrast methods for transmitted-light microscopy.

Phase contrast microscopy allows the study of highly transparent yet detail-rich specimens by producing intensity contrast from phase objects within the sample. Presented here is a generalized phase contrast illumination schema in which condenser optics are entirely abrogated, yielding a condenser-free yet highly effective method of obtaining phase contrast in transmitted-light microscopy. A ring of light emitting diodes (LEDs) is positioned within the light-path such that observation of the objective back focal plane places the illuminating ring in appropriate conjunction with the phase ring. It is demonstrated that true Zernike phase contrast is obtained, whose geometry can be flexibly manipulated to provide an arbitrary working distance between illuminator and sample. Condenser-free phase contrast is demonstrated across a range of magnifications (4–100×), numerical apertures (0.13–1.65NA) and conventional phase positions. Also demonstrated is condenser-free darkfield microscopy as well as combinatorial contrast including Rheinberg illumination and simultaneous, colour-contrasted, brightfield, darkfield and Zernike phase contrast. By providing enhanced and arbitrary working space above the preparation, a range of concurrent imaging and electrophysiological techniques will be technically facilitated. Condenser-free phase contrast is demonstrated in conjunction with scanning ion conductance microscopy (SICM), using a notched ring to admit the scanned probe. The compact, versatile LED illumination schema will further lend itself to novel next-generation transmitted-light microscopy designs. The condenser-free illumination method, using rings of independent or radially-scanned emitters, may be exploited in future in other electromagnetic wavebands, including X-rays or the infrared.

Networking strategies of the microscopy community for improved utilization of advanced instruments: (2) The national network for transmission electron microscopy and atom probe studies in France (METSA)

Abstract With the development, over the past ten years, of a new generation of electron microscopes with advanced performance, incorporating aberration correctors, monochromators, more sensitive detectors, and innovative specimen environments, quantitative measurements at the subnanometer and, in certain cases, at the unique atom level, are now accessible. However, an optimized use of these possibilities requires access to costly instruments and support by specialized trained experts. For these reasons, a national network (METSA) has been created in France with the support of CNRS and CEA in order to offer, in centres with complementary equipment and expertise, an open access to an enlarged and multidisciplinary community of academic and industrial users.

Parametric sonars in searching of buried objects

The subject of this paper is the description of usage of the parametric sonar for searching of the objects that are on the surface of the seabed or very close to it. Searching of underwater objects, especially these ones buried in the seabed has a very practical meaning. Presently more often mass destruction weapon is placed in the very difficult way to find it. Moreover searching of the objects of the archaeological character at sea requires usage of devices those have possibility of penetration of sediment which covers the searched object. In this case the most useful of acoustic means are parametric sonars that due to their specific features are good tools for underwater searching. The principle of detection of buried objects is similar to detection in the case of usage of the classical sonars. The dispersion of the sound field enables to track the object and sometimes enables to define the shape of the searched object. The measurement equipment can be connected to the Global Positioning System (GPS) and complementary equipment that is necessary in such kind of investigations. There will be presented experimental results that were obtained during the trials in the Gdansk Bay. Also will be shown the typical images for chosen objects.

Costs of Radiotherapy

A systematic assessment of radiotherapy for cancer was conducted by The Swedish Council on Technology Assessment in Health Care (SBU) in 2001. The assessment included an overview of the capacity for radiotherapy in terms of infrastructure of cancer care and an estimation of the costs of radiotherapy in Sweden. A postal questionnaire distributed to all 16 centres of radiotherapy in Sweden showed the following results: <list id="l1" type="5"> <item>In 2000 there were 57 accelerators with complementary equipment in operation, 24 of which had been installed 10 or more years ago earlier.</item><item>The total cost of external radiation therapy was estimated at SEK 427 million in the year 2000, or approximately 5% of the estimated total cost of oncology care in Sweden. The total cost of brachytherapy was estimated at SEK 43 million or about one-tenth of that of external radiotherapy.</item><item>The total cost of external radiotherapy has increased since the last inquiry (1991) by about 16% more than the general inflation in Sweden, but at the same time the volume of fractions has increased by about 37%. Thus, an increase in the efficiency of external radiotherapy, calculated per fraction, was achieved in the 1990s.</item><item>At the department level, there was a clear correlation between cost of salaries and output of fractions of external radiotherapy, thus indicating the adaptation of manpower to the volume of patients. There was an even higher correlation between the number of accelerators and the volume of fractions of radiotherapy, which suggests the occurrence of certain economies of scale in Swedish external radiotherapy.</item></list>

The Effect of Incentive regulation on Infrastructure Modernization: Local Exchange Companies' Deployment of Digital Technology

This study examines the investment patterns of all large local exchange telephone companies in the United States over time. It identifies how different regulatoy environments have influenced the recent historical pattern of investment in modern infrastructure equipment. It focuses exclusively on the postdivestiture experience of local telephone exchange companies (LECs). It examines the growth of fiber‐optic deployment and of complementary equipment associated with the modernization of today's information infrastructure. The study estimates the influence of different regulatory structures on infrastructure deployment by LECs. The study is unique in that if relates individual LEC investment patterns to LEC‐specific regulatory, demographic, and economic characteristics. Thus, it isolates the contribution of state regulatory policies from that of other demographic and economic factors in the determination of infrastructure deployment at the state LEC rather than at the corporate level. Its main findings are as follows: First, price regulation (and, in particular, price caps) is a more potent regulatory mechanism than the standard earnings sharing scheme. Second, when associated with an earnings sharing scheme, price regulation is less effective in triggering infrastructure deployment than when it is implemented by itself. These results raise questions about the effectiveness of a popular regulatory instrument‐earnings sharing schemes‐and highlight the effectiveness of generic price‐cap regulation. These results have implications for the design of regulatory policy at both the state and federal levels. In particular, given the importance currently being placed on the development of the information superhighway, regulatory emphasis should be focused more on price regulation than on regulating profits.

GPS Availability, Part II: Evaluation of State Probabilities for 21 Satellite and 24 Satellite Constellations

GPS will offer extremely high navigation performance and has a very promising future for most civil navigation needs. However, certain users consider that it may have insufficient integrity and limited availability. Sensitivity to these inadequacies varies according to size of constellation, type of user, navigation phase in which GPS is used, level of service expected, and complementary equipment operated. However, for a given constellation, GPS availability can be inferred from two fundamental factors: probability of constellation being in a given state (number of working satellites), and service availability when the constellation is in that state. This paper looks at the first of these factors by examining the consistency of the data currently being published by the civilian community on GPS system failures and availability. The paper also contains a plausible set of parameters based on a Markov chain model. These can be used to determine plausible state probabilities for a 24 satellite constellation. The analysis and results described in this paper are used in a previous paper (GPS Availability, Part I) published in the Summer 1990 issue of this journal.

GPS Availability, Part I: Availability of Service Achievable for Different Categories of Civil Users

GPS will offer extremely high navigation performance and has a promising future for most civil navigation needs. However, certain users consider that it may have insufficient integrity and limited availability. This paper describes a method for determining the availability of three different GPS services (positioning, supplemental navigation, and sole means navigation) when users also operate complementary equipment. The method is relevant to several different scenarios: two-dimensional or three-dimensional applications; different navigation phases in which GPS is being used and induced positioning accuracy requirements; and various GPS constellations, possibly supplemented by geostationary satellites. It will be shown that GPS availability is highly sensitive to all these parameters. The application discussed is the nonprecision approach phase in civil aviation, where a 21-satellite and a 24-satellite constellation are considered. The results are then extended to other flight phases and maritime users. Part II of this paper, containing state-probability analyses of 21- and 24-satellite constallations, will be published in the Fall 1990 issue of this journal. The results of Part II are a major input to Part I.
