Técnicas de diseño de pruebas en sistemas embebidos

El software es, cada vez más, una parte muy importante de cualquier circuito electrónico moderno, por ejemplo, un circuito realizado con algún tipo de microprocesador debe incorporar un programa de control por pequeño que sea. Al utilizarse programas informáticos en los circuitos electrónicos modernos, es muy aconsejable, por no decir imprescindible, realizar una serie de pruebas de calidad del diseño realizado. Estas pruebas son cada vez más complicadas de realizar debido al gran tamaño del software empleado en los sistemas actuales, por este motivo, es necesario estructurar una serie de pruebas con el fin de realizar un sistema de calidad, y en algunos casos, un sistema que no presente ningún peligro para el ser humano o el medio ambiente. Esta propuesta consta de la explicación de las técnicas de diseño de pruebas que existen actualmente (por lo menos las más básicas ya que es un tema muy extenso) para realizar el control de calidad del software que puede contener un sistema embebido. Además, muchos circuitos electrónicos, debido a su control o exigencia hardware, es imprescindible que sean manipulados por algún programa que requiera más que un simple microprocesador, me refiero a que se deban controlar por medio de un pequeño programa manipulado por un sistema operativo, ya sea Linux, AIX, Unix, Windows, etc., en este caso el control de calidad se debería llevar a cabo con otras técnicas de diseño. También se puede dar el caso que el circuito electrónico a controlar se deba hacer por medio de una página web. El objetivo es realizar un estudio de las actuales técnicas de diseño de pruebas que están orientadas al desarrollo de sistemas embebidos. ABSTRACT. Software is increasingly a very important part of any modern electronic circuit, for example, a circuit made with some type of microprocessor must incorporate a control program no matter the small it is. When computer programs are used in modern electronic circuits, it is quite advisable if not indispensable to perform a series of quality tests of the design. These tests are becoming more and more difficult to be performed due to the large size of the software used in current systems, which is why it is necessary to structure a series of tests in order to perform a quality system, and in some cases, a system with no danger to humans or to the environment. This proposal consists of an explanation of the techniques used in the tests (at least the most basic ones since it is a very large topic) for quality control of software which may contain an embedded system. In addition, a lot of electronic circuits, due to its control or required hardware, it is essential to be manipulated by a program that requires more than a simple microprocessor, I mean that they must be controlled by means of a small program handled by an operating system, being Linux, AIX, Unix, Windows, etc., in this case the quality control should be carried out with other design techniques. The objective is to study the current test design techniques that are geared to the development of embedded systems. It can also occur that the electronic circuit should be controlled by means of a web page.

Introducción de las plataformas tecnológicas 2.0 y la innovación abierta en la estrategia empresarial: estudio del sector de componentes electrónicos

Este proyecto se encuadra dentro de los estudios de impacto que están produciendo en las empresas el desarrollo e incorporación de las nuevas tecnologías, y más concretamente la implantación de las aplicaciones provenientes de la denominada web 2.0. Se conoce con este nombre a las herramientas web que permiten una comunicación bidireccional, es decir, el usuario y la empresa pueden intercambiar opiniones, de manera que el usuario adquiere un nuevo papel más protagonista, presentando ideas, aclaraciones, gustos, críticas...que son tenidas en cuenta por la empresa para realizar su actividad. De esta manera se ha roto con el modelo anterior donde el usuario solo podía consultar la información de una página web, era simple receptor de la información. El objetivo de este estudio es conocer cómo las empresas están incorporando estas tecnologías 2.0 a su estrategia empresarial, y cómo términos como innovación abierta o co-creación están tomando mayor importancia en el entorno empresarial gracias a estas nuevas tecnologías. Si bien existen estudios a nivel de consultoría que generalmente aportan información sobre cuáles son las plataformas 2.0 más utilizadas en el mundo empresarial, no se han encontrado hasta ahora estudios que vinculen estas plataformas entre ellas y con la estructura empresarial, para poder definir un perfil de la organización que trabaja con ellas o el nivel de madurez de la incorporación de estas tecnologías en las organizaciones. Analizar cualitativamente estos aspectos, significa estudiar los nuevos conceptos incorporados a las tecnologías 2.0 en la empresa. Un análisis cuantitativo nos llevaría a estudiar de manera práctica que tipo de recursos y en qué cantidad se están utilizando y su vinculación con la estructura de la organización. Para ello: En una primera parte, nos centraremos en las diferentes formas en las que se puede acceder a Internet, y a continuación enfocaremos el estudio en los dispositivos móviles que nos permiten la conexión desde cualquier lugar y en cualquier instante. Con esto conseguiremos tener una situación actual del mercado de las TIC y veremos cómo las empresas han ido construyendo nuevas políticas para cambiar su estrategia con el fin de estar presentes en los nuevos dispositivos móviles y no perder cuota de mercado. Tras ello, veremos porqué conceptos como el de innovación abierta y proceso de co-creación han sido posibles gracias a la implantación de las tecnologías 2.0 en el ámbito empresarial, facilitando que la empresa y el usuario final cooperen y vayan de la mano en una misma dirección; la empresa se surte de las aportaciones que los usuarios ofrecen, y por otra parte el usuario se siente valorado por la empresa para conseguir la meta final. Es aquí donde comprobaremos la transformación que ha sufrido la empresa en sus distintos sectores departamentales (marketing, ventas, recursos humanos y atención al cliente) como consecuencia de la incorporación de las herramientas 2.0 al mundo laboral. Por todo ello, se enumerarán los distintos usos que realizan las empresas de las redes social más habituales, y además se describirán las principales herramientas y/o aplicaciones para monitorizar las redes sociales que servirán a la empresa para hacer un seguimiento de las mismas. La segunda parte del proyecto será un caso práctico y servirá para ofrecer una visión más real del estado actual de las empresas y su relación con las redes sociales. Para la recopilación de los datos se han escogido las empresas que pertenecen al sector de la “Fabricación de productos informáticos, electrónicos y ópticos”. En cuento a las redes sociales elegidas, han sido Facebook y Twitter. Este estudio práctico nos hará entender mejor el impacto directo que tienen las redes sociales en la actividad diaria de las empresas. Finalmente se realizarán una serie de consideraciones a modo de directrices que servirán para tratar de entender cómo se están utilizando las redes sociales en el entorno empresarial y cuál puede ser la manera más óptima de utilizarlas según el estudio presentado. ABSTRACT. This project is part of the impact studies arisen in companies by the development and incorporation of new technologies and, specifically, by the implementation of applications from the so-called web 2.0. That is how we call the web tools that allow bidirectional communication, this is, user and company can exchange opinions, in such a way that users acquire a leading role, submitting ideas, explanations, preferences, criticism... considered by the company when performing its activities. This way, we have broken with the previous model, where users could only check information from a web page and were simple information recipients. The objective of this study is to get to know how companies are incorporating these technologies 2.0 to their business strategy and how terms such as open innovation or co-creation are becoming more important in the business sphere thanks to these new technologies. Even if there are consulting studies that generally provide information about which are the platforms 2.0 more used in the business world, no studies have been found until now that link such platforms among them and with the business structure, in order to define a profile of the organization that works with them or the level of development of the incorporation of these technologies in the organizations. A qualitative analysis of these aspects involves studying the new concepts incorporated to technologies 2.0 by companies. A qualitative analysis would lead us to study in a practical manner what kind of resources and what amount are being used and their relation with the organization structure. Therefore: First, we will focus on the different ways to gain access to the Internet and, afterwards, we will focus the study on mobile devices that allow us to be connected everywhere any time. This way, we will manage to obtain a present situation of the ICT market and we will see how companies have constructed new policies to change their strategy in order to be present in the new mobile devices without losing their market share. Later, we will review why concepts such as open innovation and co-creation process have been possible thanks to the implementation of technologies 2.0 in the business environment, facilitating that companies and final users cooperate and walk hand in hand in the same direction; companies stock up on the contributions offered by users and, on the other hand, users feel appreciated by companies in the achievement of the final goal. Here we will confirm the transformation suffering by companies in different department sectors (marketing, sales, human resources and customer service) as a result of the incorporation of tools 2.0 to the work environment. Therefore, we will enumerate the different uses that companies make of the most common social networks, describing the main tools and/or applications to monitor social networks used by companies to follow them up. The second part of the project will be a case study to offer a more real vision of the present status of companies and their relation with social networks. To collect the data, we have selected companies from the “Manufacture of computer, electronic and optical products” industry. The social networks chosen are Facebook and Twitter. This case study will help us to get a better understanding of the direct impact of social networks in companies’ daily activity. Finally, we will offer a series of considerations and guidelines to try to understand how are social networks being used in the business environment and what can be the most suitable manner to use them according to this study.

Fostering English-taught higher education programs in a Spanish university: the "TechEnglish" innovative project

In recent years, coinciding with adjustments to the Bologna process, many European universities have attempted to improve their international profile by increasing course offerings in English. According to the Institute of International Education (IIE), Spain has notably increased its English-taught higher education programs, ranking fifth in the list of European countries by number of English-taught Master's programs in 2013. This article presents the goals and preliminary results of an on-going innovative education project (TechEnglish) that aims to promote course offerings in English at the Technical University of Madrid (Universidad Politécnica de Madrid, UPM). The UPM is the oldest and largest of all Technical Universities in Spain. It offers graduate and postgraduate programs that cover all the engineering disciplines as well as architecture. Currently, the UPM has no specific bilingual/multilingual program to promote teaching in English, although there is an Educational Model Whitepaper (with a focus on undergraduate degrees) that promotes the development of activities like an International Semester or a unique shared curriculum. The TechEnglish project is an attempt to foster courses taught in English at 7 UPM Technical Schools, including students and 80 faculty members. Four tasks were identified: (1) to design a university wide framework to increase course offerings, (2) to identify administrative difficulties, (3) to increase visibility of courses offered, and (4) to disseminate the results of the project. First, to design a program we analyzed existing programs at other Spanish universities, and other projects and efforts already under way at the UPM. A total of 13 plans were analyzed and classified according to their relation with students (learning), professors (teaching), administration, course offerings, other actors/institutions within the university (e.g., language departments), funds and projects, dissemination activities, mobility plans and quality control. Second, to begin to identify administrative and organizational difficulties in the implementation of teaching in English, we first estimated the current and potential course offerings at the undergraduate level at the UPM using a survey (student, teacher and administrative demand, level of English and willingness to work in English). Third, to make the course offerings more attractive for both Spanish and international students we examined the way the most prestigious universities in Spain and in Europe try to improve the visibility of their academic offerings in English. Finally, to disseminate the results of the project we created a web page and a workspace on the Moodle education platform and prepared conferences and workshops within the UPM. Preliminary results show that increasing course offerings in English is an important step to promote the internationalization of the University. The main difficulties identified at the UPM were related to how to acknowledge/certify the departments, teachers or students involved in English courses, how students should register for the courses, how departments should split and schedule the courses (Spanish and English), and the lack of qualified personnel. A concerted effort could be made to increase the visibility of English-taught programs offered on-line.

15M. La expresión del conflicto en las canciones protestas

El objetivo de esta comunicación es analizar de manera exploratoria en qué forma las letras de las canciones protesta, escritas en el entorno de las movilizaciones del 15M, contienen una visión del mundo social, económico y político. Las canciones protesta se caracterizan por la denuncia social de situaciones de explotación, discriminación o esclavitud. El rasgo común a todas ellas es la existencia de un conflicto, al que responden tomando posición por una de las partes o apelando a la paz y al consenso. En ocasiones ofrecen soluciones a dichos conflictos, si bien no es la situación más extendida. En relación a las canciones del 15M, emplearemos como referencia las disponibles en la página de la Fundación Robo. En dicha página se alojan canciones cuyo nexo de unión es la protesta por la situación que vive la sociedad española. Tomando las canciones como datos de análisis, se estudiarán los estilos más empleados para protestar, el empleo del “bricoleur” (Levi-Strauss) de músicas y letras para recomponer un nuevo mensaje y finalmente se considerará la presencia de dualizaciones como las de “nosotros” y “ellos”. Se exploran las razones que se exponen en las letras para llegar al conflicto actual y las soluciones que se proponen. Tras definir qué actores y colectivos definen cada uno de los grupos, se consideran las relaciones que se proponen entre ellos. Destacan los planteamientos que presentan la relación como de lucha o conflicto, mientras que la oferta de relaciones constructivas, ya sea de diálogo, consenso o negociación, es prácticamente inexistente. Raramente ofrecen una solución pacífica a los conflictos.

The management improvement initiative : progress report to the General Assembly, Public Act 97-0558 /

On August 25, 2011, Governor Pat Quinn signed House Bill 1488 into law, now Public Act 97-0558 (The Act). The Act specifically directs a Management Improvement Initiative Committee (The Committee) to implement recommendations outlined in the January 2011 report to the General Assembly as required under Public Act 96-1141. The Act directs the group, formed under the auspices of Public Act 96-1141, to continue their work based on categories of recommendations. Each recommendation area has the common goal of reviewing providers from redundant monitoring, auditing, and reporting requirements. Implementing the recommendations of the Act will result in efficiency in business process for our providers, reinvestment of dollars saved from inefficient or unrealized administrative costs, and ultimately foster a network of sustainable human services providers in Illinois while increasing the level of direct service by the State agencies, contracted providers, and communities, who are all facing current economic pressures in the fiscal crisis.

Economic Survey of Latin America and the Caribbean 2016: The 2030 Agenda for Sustainable Development and the challenges of financing for development

This, the sixty-eighth edition of the Economic Survey of Latin America and the Caribbean, which corresponds to the year 2016, consists of three parts. Part I outlines the region’s economic performance in 2015 and analyses trends in the first half of 2016, as well as the outlook for the rest of the year. It examines the external and internal factors influencing the region’s economic performance and highlights some of the macroeconomic policy challenges that have arisen in an external context of weak growth and high levels of uncertainty. Part II analyses the challenges that the countries of Latin America and the Caribbean face at the domestic and international levels in mobilizing financing for development. On the domestic front, slower growth and tighter fiscal restrictions pose significant challenges for the mobilization of resources. Externally, the classification of many of the region’s countries in the middle-income category limits their access to concessional external financing or international support. Part III of this publication may be accessed on the web page of the Economic Commission for Latin America and the Caribbean (www.eclac.org). It contains the notes relating to the economic performance of the countries of Latin America and the Caribbean in 2015 and the first half of 2016, together with their respective statistical annexes. The cut-off date for updating the statistical information in this publication was 30 June 2016.

Editorial

Welcome to the latest issue of Contact Lens and Anterior Eye. In this issue, Kuldeep Razaida provides a fascinating look at fitting prosthetic lenses to patients in India. I had the good fortune of visiting his clinic in August 2006 at the LV Prasad Eye Institute in Hyderabad, India and was humbled by the vast expertise within the one building. The institute started in 1987 and is the brainchild of the infamous Professor Rao. I think there are few such places in the world where the clinicians work so passionately in treating such interesting patients (for details regarding the LV Prasad Eye Institute see www.lvpei.org). I was in Hyderabad courtesy of IACLE (see issue 29:5 for an editorial by Judith Morris and Sonja Cronje about IACLE) and was able to share ideas with contact lens educators from across the world (for more information on IACLE see www.iacle.org). The issue contains some regular contact lens type papers too; with our aging population readers will be particularly interested in a paper by Mike Freeman and Neil Charman looking at modified monovision with diffractive bifocal lenses. There is an article looking at visual problems with video display terminal use and a study looking at the effects of surface treatment of silicone hydrogel contact lenses. There is an interesting piece from Dr Aisling Mann of Aston University looking at tear protein analysis; this article contains one CET point too for readers who complete the attached multiple choice questions before the relevant deadline. Also, congratulations to the BCLA members who successfully undertook the Fellowship of the BCLA at this year's BCLA conference in Manchester. If you are interested in undertaking the Fellowship please look at the details on the BCLA web page (http://www.bcla.org.uk/fellowship.asp). Amongst the case reports in this issue of CLAE you will notice one from Andrew Elder-Smith, this particular case report was presented as part of his successful Fellowship submission in 2006 and was thought to be of particular good quality by the examiners who asked Andrew to kindly submit it for publication to Contact Lens and Anterior Eye as an example for potential candidates. Finally, it is my sad duty to report the death of Howard Gee earlier this year, a past council member of the BCLA. Our thoughts and prayers are with his family and friends.

Editorial

The American Academy of Optometry (AAO) had their annual meeting in San Diego in December 2005 and the BCLA and CLAE were well represented there. The BCLA does have a reasonable number of non-UK based members and hopefully in the future will attract more. This will certainly be beneficial to the society as a whole and may draw more delegates to the BCLA annual conference. To increase awareness of the BCLA at the AAO a special evening seminar was arranged where BCLA president Dr. James Wolffsohn gave his presidential address. Dr. Wolffsohn has given the presidential address in the UK, Ireland, Hong Kong and Japan – making it the most travelled presidential address for the BCLA to date. Aside from the BCLA activity at the AAO there were numerous lectures of interest to all, truly a “something for everyone” meeting. All the sessions were multi-track (often up to 10 things occurring at the same time) and the biggest dilemma was often deciding what to attend and more importantly what you will miss! Nearly 200 new AAO Fellows were inducted at the Gala Dinner from many countries including 3 new fellows from the UK (this year they all just happened to be from Aston University!). It is certainly one of the highlights of the AAO to see fellows from different schools of training from around the world fulfilling the same criteria and being duly rewarded for their commitment to the profession. BCLA members will be aware that 2006 sees the introduction of the new fellowship scheme of the BCLA and by the time you read this the first set of fellowship examinations will have taken place. For more details of the FBCLA scheme see the BCLA web site http://www.bcla.org.uk. Since many of CLAE's editorial panel were at the AAO an informal meeting and dinner was arranged for them where ideas were exchanged about the future of the journal. It is envisaged that the panel will meet twice a year – the next meeting will be at the BCLA conference. The biggest excitement by far was the fact that CLAE is now Medline/PubMed indexed. You may ask why is this significant to CLAE? PubMed is the free web-based service from the US National Library of Medicine. It holds over 15 million biomedical citations and abstracts from the Medline database. Medline is the largest component of PubMed and covers over 4800 journals published in more than 70 countries. The impact of this is that CLAE is starting to attract more submissions as researchers and authors are not worried that their work will not be hidden from other colleagues in the field but rather the work is available to view on the World Wide Web. CLAE is one of a very small number of contact lens journals that is indexed this way. Amongst the other CL journals listed you will note that the International Contact Lens Clinic has now merged with CLAE and the journal CLAO has been renamed Eye and Contact Lenses – making the list of indexed CL journals even smaller than it appears. The on-line submission and reviewing system introduced in 2005 has also made it easier for authors to submit their work and easier for reviewers to check the content. This ease of use has lead to quicker times from submission to publication. Looking back at the articles published in CLAE in 2005 reveals some interesting facts. The majority of the material still tends to be from UK groups related to the field of Optometry, although we hope that in the future we will attract more work from non-UK groups and also from non-Optometric areas such as refractive surgery or anterior eye pathology. Interestingly in 2005 the most downloaded article from CLAE was “Wavefront technology: Past, present and future” by Professor W. Neil Charman, who was also the recipient of the Charles F. Prentice award at the AAO – one of the highest awards honours that the AAO can bestow. Professor Charman was also the keynote speaker at the BCLA's first Pioneer's Day meeting in 2004. In 2006, readers of CLAE will notice more changes, firstly we are moving to 5 issues per year. It is hoped that in the future, depending on increased submissions, a move to 6 issues may be feasible. Secondly, CLAE will aim to have one article per issue that carries CL CET points. You will see in this issue there is an article from Professor Mark Wilcox (who was a keynote speaker at the BCLA conference in 2005). In future articles that carry CET points will be either reviews from BCLA conference keynote speakers, members of the editorial panel or material from other invited persons that will be of interest to the readership of CLAE. Finally, in 2006, you will notice a change to the Editorial Panel, some of the distinguished panel felt that it was good time to step down and new members have been invited to join the remaining panel. The panel represent some of the most eminent names in the fields of contact lenses and/or anterior eye and have varying backgrounds and interests from many of the prominent institutions around the world. One of the tasks that the Editorial Panel undertake is to seek out possible submissions to the journal, either from conferences they attend (posters and papers that they will see and hear) and from their own research teams. However, on behalf of CLAE I would like to extend that invitation to seek original articles to all readers – if you hear a talk and think it could make a suitable publication to CLAE please ask the presenters to submit the work via the on-line submission system. If you found the work interesting then the chances are so will others. CLAE invites submissions that are original research, full length articles, short case reports, full review articles, technical reports and letters to the editor. The on-line submission web page is http://www.ees.elsevier.com/clae/.

Do educators need educating?

Actual text: I was recently at the Spanish College of Optometry biennial conference and attended a meeting of contact lens lecturers from around Spain and Portugal. We discussed various ideas, mainly about how to share good practice and improve standards. What came to my mind was ‘is there a blueprint for training trainers?’ Well probably not but there are many things that we need to acknowledge such as the way students learn for example. Many educators themselves were taught by lecturers who would write on a blackboard or use acetate on an overhead projector, then came the 35 mm slide era followed by the Powerpoint era. More recently there is a move towards a much more integrated approach of various teaching methods. At my university our contact lens and anterior eye lectures generally follow a format where a narrated Powerpoint lecture is uploaded onto our internal virtual learning environment. This narrated version of the slides is designed to give the didactic element of the topic. The students listen to that before attending an interactive seminar on that topic. The seminar is also recorded so that students can listen to that afterwards. The seminar is designed to give additional information, such as case reports, or to clarify key points or for live demonstrations. It is a good way of doubling the contact time with the students without imposing further on an already packed formal timetable as the students can work in their own time. One problem that we noticed with this approach was that attendance can vary. If the students feel that they will gain something from the interactive seminar then they are more likely to attend – exam tips usually win them over! At the Spanish meeting the educators decided that they wanted to have regular meetings. The industry colleagues in attendance said that they were happy to help but could not necessarily give money, but they could offer meeting rooms, pay for lunch and evening meals. They even said that that they were happy to host meetings and invite other companies too (except to manufacturing plants). In the UK the British Committee of Contact Lens Educators (BUCCLE) meets for one day on three occasions in the year. The American Optometric Contact Lens Educators (AOCLE) meets annually at a three day event. Both these organisations get some help from industry. BUCCLE usually has one of its meetings at a university, one at a company training centre/manufacturing plant/national headquarters and one meeting the day before the BCLA annual conference. BUCCLE usually has its pre-BCLA meeting in conjunction with the International Association of Contact Lens Educators (IACLE). So when educators meet what would they discuss; well probably the focus should be on education rather than actual contact lens knowledge. For example sharing ideas on how to teach toric lens fitting would be better than discussing the actual topic of toric lenses itself. Most universities will have an education department with an expert who could share ideas on how to use the internet in teaching or how to structure lectures or assessments etc. In the past I have helped with similar training programmes in other countries and sharing good practice in pedagogy is always a popular topic. Anyone who is involved in education in the field of contact lenses should look at the IACLE web page and look out for the IACLE World Congress in 2015 in the days preceding the BCLA. Finally, IACLE, AOCLE and BUCCLE all exist as a result of generous educational grants from contact lens companies and anyone interested in finding out more about should refer to their respective web pages.

CLAE to move to online format

Editorial: The 2015 BCLA annual conference was another fantastic affair. It was the first time the conference was held in the beautiful city of Liverpool. The venue was great and the programme was excellent. The venue overlooked the River Mersey and many of the hotels were local boutique hotels. I stayed in one which was formerly the offices of White Star Liners—where the RMS Titanic was originally registered. The hotel decor was consistent with its historic significance. The BCLA gala dinner was held in the hugely impressive Anglican Cathedral with entertainment from a Beatles tribute band. That will certainly be a hard act to follow at the next conference in 2017. Brian Tompkins took the reigns as the new BCLA president. Professor Fiona Stapleton was the recipient of the BCLA Gold Medal Award. The winner of the poster competition was Dorota Szczesna-Iskander with a poster entitled ‘Dry Contact lens poor wettability and visual performance’. Second place was Renee Reeder with her poster entitled ‘Abnormal Rosacea as a differential diagnosis in corneal scarring’. And third place was Maria Jesus Gonzalez-Garcia with her poster entitled ‘Dry Effect of the Environmental Conditions on Tear Inflammatory Mediators Concentration in Contact Lens Wearers’. The photographic competition winner was Professor Wolfgang Sickenberger from Jena in Germany. The Editorial Panel of CLAE met at the BCLA conference for their first biannual meeting. The journal metrics were discussed. In terms of number of submissions of new papers CLAE seems to have plateaued after seeing a rapid growth in the number of submissions over the last few years. The increase over the last few years could be attributed to the fact that CLAE was awarded an impact factor for the first time in 2012. This year it seems that impact factors across nearly all ophthalmic related journals has dropped. This could in part be due to the fact that last year was a ‘Research Exercise Framework (REF) year for UK universities, where they are judged on quality of their research output. The next REF is in 2020 so we may see changes nearing that time. Looking at article downloads, there seems to be a continued rise in figures. Currently CLAE attracts around 85,000 downloads per year (this is an increase of around 10,000 per year for the last few years) and the 2015 prediction is 120,000! With this in mind and with other contributing factors too, the BCLA has decided to move to online delivery of CLAE to its members starting from issue 5 of 2015. Some members do like to flick through the pages of a hard copy of the journal so members will still have the option of receiving a hard copy through the post but the default journal delivery method will now be online. The BCLA office will send various alerts and content details to members email addresses. To access CLAE online you will need to log in via the BCLA web page, currently you then click on ‘Resources’ and then under ‘Free and Discounted Publications’ you will see CLAE. This actually takes you to CLAE’s own webpage (www.contactlensjournal.com) but you need to log in via the BCLA web page. The BCLA plans to change these weblinks so that from the BCLA web page you can link to the journal website much more easily and you have the choice of going directly into the general website for CLAE or straight to the current issue. In 2016 you will see an even easier way of accessing CLAE online as the BCLA will launch a CLAE application for mobile devices where the journal can be downloaded as a ‘flick-book’. This is a great way of bringing CLAE into the modern era where people access their information in newer ways. For many the BCLA conference was part of a very busy conference week as it was preceded by the International Association of Contact Lens Educators’ (IACLE) Third World Congress, held in Manchester on the 4 days before the BCLA conference. The first and second IACE World Congresses were held in Waterloo, Canada in 1994 and 2000 respectively and hosted by Professor Des Fonn. Professor Fonn was the recipient of the first ever IACLE lifetime achievement award. The Third IACLE World Congress saw more than 100 contact lens educators and industry representatives from around 30 countries gather in the UK for the four-day event, hosted by The University of Manchester. Delegates gained hands-on experience of innovations in teaching, such as learning delivery systems, the use of iPads in the classroom and for creating ePub content, and augmented and virtual reality technologies. IACLE members around the world also took part via a live online broadcast. The Third IACLE World Congress was made possible by the generous support of Sponsors Alcon, CooperVision and Johnson & Johnson Vision Care., for more information look at the IACLE web page (www.iacle.org).

Internet Protocol Television (IPTV) controller realization with Very Large Scale Integration (VLSI) modules

Internet Protocol Television (IPTV) is a system where a digital television service is delivered by using Internet Protocol over a network infrastructure. There is considerable confusion and concern about the IPTV, since two different technologies have to be mended together to provide the end customers with some thing better than the conventional television. In this research, functional architecture of the IPTV system was investigated. Very Large Scale Integration based system for streaming server controller were designed and different ways of hosting a web server which can be used to send the control signals to the streaming server controller were studied. The web server accepts inputs from the keyboard and FPGA board switches and depending on the preset configuration the server will open a selected web page and also sends the control signals to the streaming server controller. It was observed that the applications run faster on PowerPC since it is embedded into the FPGA. Commercial market and Global deployment of IPTV were discussed.

Estimate of the (R)USLE rainfall erosivity factor from monthly precipitation data in mainland Spain

The need for continuous recording rain gauges makes it difficult to determine the rainfall erosivity factor (R-factor) of the (R)USLE model in areas without good temporal data coverage. In mainland Spain, the Nature Conservation Institute (ICONA) determined the R-factor at few selected pluviographs, so simple estimates of the R-factor are definitely of great interest. The objectives of this study were: (1) to identify a readily available estimate of the R-factor for mainland Spain; (2) to discuss the applicability of a single (global) estimate based on analysis of regional results; (3) to evaluate the effect of record length on estimate precision and accuracy; and (4) to validate an available regression model developed by ICONA. Four estimators based on monthly precipitation were computed at 74 rainfall stations throughout mainland Spain. The regression analysis conducted at a global level clearly showed that modified Fournier index (MFI) ranked first among all assessed indexes. Applicability of this preliminary global model across mainland Spain was evaluated by analyzing regression results obtained at a regional level. It was found that three contiguous regions of eastern Spain (Catalonia, Valencian Community and Murcia) could have a different rainfall erosivity pattern, so a new regression analysis was conducted by dividing mainland Spain into two areas: Eastern Spain and plateau-lowland area. A comparative analysis concluded that the bi-areal regression model based on MFI for a 10-year record length provided a simple, precise and accurate estimate of the R-factor in mainland Spain. Finally, validation of the regression model proposed by ICONA showed that R-ICONA index overpredicted the R-factor by approximately 19%.
