Towards the integration of user interface prototyping and model-based development

The main objective of this paper is to make a contribution in the automation of web applications’ development, starting from prototypes of their graphical user interfaces. Due to the exponential increase in the use of internet-based services and applications, there is an also increasing demand for Web designers and developers. At the same time, the proliferation of languages, frameworks and libraries illustrates the current state of immaturity of web development technologies. This state of affairs creates difficulties in the development and maintenance of Web applications. In this paper, we argue that integrating concepts of modelbased user interface development with the more traditional usercentred design approach to development can provide an answer to this situation. An approach is presented that allows designers to use prototyping tools, in this case Adobe XD, to design graphical interfaces, and then automatically converts them to (Vue.js + Bootstrap) code, thus creating a first version of the implementation for further development. This is done through the interpretation of the SVG file that Adobe XD exports.FCT -Fundação para a Ciência e a Tecnologia(UIDB/50014/2020

A tabular editor for user interfaces modelling

The IVY workbench is a model-based tool for the automated analysis of interactive systems. Models are written in a domain specific language, MAL interactors, using a textual editor. This language has shown to be the main barrier for tool adoption by inexperienced users. We propose a new editor, which eases modelling, in order to lower the tool’s learning curve.Trabalho realizado no ambito do projecto “NORTE-01- ˆ 0145-FEDER-000016” financiado pelo Programa Operacional Regional do Norte (NORTE 2020), PORTUGAL 2020 e Uniao˜ Europeia, atraves do Fundo Europeu para o Desenvolvimento ´ Regional (FEDER).info:eu-repo/semantics/publishedVersio

MODUS: uma metodologia de prototipagem de interfaces baseada em modelos

A interface de utilizador é essencial para o sucesso de uma aplicação, ora a sua implementação requer tempo e esforço. Metodologias baseadas em modelos suportadas por uma geração automática têm sido propostas como solução para reduzir os custos de desenvolvimento. No entanto, um elevado nível de automação nestas abordagens requer o uso de modelos detalhados da interface, originando complicações. Por um lado, esta perspetiva é contrária a uma conceção baseada no progressivo refinamento de mockups, típica do desenvolvimento de interfaces. Por outro lado, obriga uma distinção entre os modelos utilizados na lógica de negócio e na interface. Este artigo propõe uma abordagem para gerar a interface de utilizador baseada diretamente em modelos estruturais da lógica de negócio. A identificação do domínio de aplicação é um factor chave da metodologia, permitindo automatizar o processo de geração. Por sua vez a separação entre conteúdo e forma favorece o refinamento iterativo das interfaces geradas.info:eu-repo/semantics/publishedVersio

MODUS: model-based user interfaces prototyping

Model-based methodologies, supported by automatic generation, have been proposed as a solution to reduce software development costs. In the case of interactive computing systems specific challenges arise. On the one hand, a high level of automation requires the use of detailed models, which is contrary to the iterative development process, based on the progressive refinement of user interface mockups, typical of user centered development processes. On the other hand, layered software architectures imply a distinction between the models used in the business logic and in the user interface, raising consistency problems between the models at each level. This article proposes a tool supported approach to user interface generation directly from the architectural models of the business logic. In many situations, user interfaces provide similar features inside a specific domain. The identification of the application domain is thus a key factor in supporting the automation of the generation process.This work was financed by the ERDF – European Regional Development Fund through the Operational Programme for Competitiveness and Internationalisation - COMPETE 2020 Programme, and by National Funds through the FCT – Fundação para a Ciência e a Tecnologia (Portuguese Foundation for Science and Technology) within project POCI-01-0145- FEDER-006961.info:eu-repo/semantics/publishedVersio

Intelligent cutting-off of pipes and bars

Traditionally, automatic cutting-off machines, of metallic pipes or bars, use a constant cutting velocity mode. This mode of operation, constant cutting velocity combined with different profiles of materials to be cut, exposes the cutting saw to variable cutting forces. Therefore, the cutting off machine is usually set for the worst expected conditions, otherwise excessive wear of the saw and machine will occur. Further, traditional cutting-off machines require the adjustment of the position of a limit switch in order to automatically detect when the cut of a piece has been completed. The aim of this paper is to study the application of control algorithms to the process of cutting-off metallic pipes or bars, with variable profiles, implemented in an industrial cutting-off machine, commercially available. The presented algorithms concern realtime cutting control and automatic detection of the cutting end. The algorithms are implemented in a low cost Programmable Logic Controller (PLC), allowing its use in industrial applications without significant increase on machine cost. All algorithms were developed having in mind safety issues relative to the operation of the cutting machine in order to prevent catastrophic failure. Also, all process related relevant parameters are monitored on a Personal Computer using OPC (Object Linking and Embedding – for Process Control)

Carcinogenic Ability of Schistosoma Haematobium Possibly through Oncogenic Mutation of KRAS Gene

Schistosoma haematobium is a parasitic flatworm that infects millions of people, mostly in the developing world, and is associated with high incidence of bladder cancer, although why is not clear. Previously, we have used CD-1 mice to show that Schistosoma haematobium total antigen (Sh) has a carcinogenic ability. Sh intravesically instillation induced the development of several urothelial lesions, namely nodular hyperplasia and dysplasia (LGIUN—Low Grade Intra-Urothelial Neoplasia) after 40 weeks of treatment. These results suggested that Sh induce urothelium malignization. Bladder carcinoma frequently harbours gene mutations that constitutively activate the receptor tyrosine kinase-Ras pathway for this reason we studied activating mutations in KRAS gene. Twenty percent of the bladders with dysplasia presented a KRAS mutation in codon 12 of exon 2. We concluded from these results that the parasite extract of S. haematobium has carcinogenic ability possibly through oncogenic mutation of KRAS gene

The indirect effect of body image on distress in women with breast cancer undergoing chemotherapy

BACKGROUND This study assessed the indirect effect of body image in the relationship between illness duration, optimism, coping strategies and psychological distress as well as the moderator role of being or not submitted to surgery and type of surgery, in women with breast cancer undergoing chemotherapy.PARTICIPANTS AND PROCEDURE This cross-sectional study included eighty-seven women with breast cancer undergoing chemotherapy, who answered instruments that assessed sociodemographic and clinical issues, optimism, coping, concerns with body image and psychological distress. Bayesian statistics were performed to test the indirect effect model that included also the moderator effects.RESULTS Lower optimism, lower use of humor, and higher denial and illness duration predicted lower body image and high er distress. Longer illness duration was associated with higher distress. Body image had an indirect effect in the relationship between optimism and distress; between denial coping and distress; between humor coping and distress and between illness duration and distress. Being submitted to surgery but not the type of surgery was a moderator in the indirect effect model.CONCLUSIONS Body image is critical to psychological distress. Future interventions for women with breast cancer should consider body image as a target, in order to promote adaptive coping strategies specially when women have had surgery
