Academical and Research Wiimote Applications

IADIS MULTI CONFERENCE ON COMPUTER SCIENCE AND INFORMATION SYSTEMS 2008 Amsterdam, The Netherlands JULY 22 - 24, 2008This paper proposes the employment of the Wii Remote controller, better known as Wiimote, as an useful tool for educators and researchers. The quick development on fields such as Wireless Sensors and Actuators Networks or Hybrid Systems, and their applications, requires engineers with a solid knowledge in these areas. To achieve this goal the Wiimote becomes a great alternative to other options due to its great variety of analog and digital components, for a very low price, and the good documentation about it existing in Internet. As will be seen in this paper, the possible academical and research uses of the Wiimote are almost endless and cover many interesting problems in control engineering

Investigating how queer people of color use ICTs to cope with stigma

Stigma is an attribute that differentiates and negatively classifies an individual within a specific categorized identity. Multiple identities are stigmatized, such as the LGBTQ and PoC communities. When these identities are layered on top of one another, so are the stigmas associated with them, and this creates an increased risk of negative consequences. Literature indicates that a way to ameliorate these negative consequences is to find ways to cope. This lit- erature review analyzes the current research regarding what is known about how QPOC leverage ICTs as a tool for coping with stigma. Overall, it was found that not much is known about the particular ICTs QPoC are leveraging to cope, nor is there much knowledge on how they are using these unidentified ICTs. Further research is necessary to better understand what ICTs are being used and how QPoC are using them in order to help ameliorate the negative consequences of stigma

Activity and efficiency trends for the residential sector across countries

The residential sector is a major contributor to climate change, accounting for almost a quarter of global energy consumption and a fifth of CO2 emissions in 2019. Since 2000, residential consumption has grown at a sustained rate of 1%/year, driven by the development of emerging economies, despite stagnation in developed countries. The increasing demand for living space, energy services and comfort levels seems difficult to curb, especially in the developing world on its fair attempt to reduce inequality. To understand these trends, this paper analyses the trajectories of key indicators of activity and efficiency in this sector, for emerging and developed regions, as well as for major consuming nations, mainly China, United States, European Union, Russia, India, Japan and Brazil. Despite data limitations, meaningful cross-country comparisons are presented for fuel mixes, energy services and dwelling types. Heating, ventilation and air conditioning (HVAC) systems account for a third of residential consumption and will grow rapidly as increasing wealth in emerging economies allows for satisfying the thermal comfort demand. Economic development will naturally increase housing size and equipment level and reduce household size, and could close the per capita consumption gap between developing and developed regions. Efficiency improvements could reduce the energy use intensity to around 10 koe/m(2) but will not be enough to curb residential consumption. International cooperation, policy support and funding are essential to accelerate development and efficiency gains in developing countries without compromising environmental targets. In the meantime, politicians should focus on decarbonising the energy mix and promoting energy efficiency, while citizens focus on energy conservation to avoid irreversible environmental damage.

Ophthalmic Manifestations of Congenital Zika Syndrome in Colombia and Venezuela

IMPORTANCE The ocular manifestations and sequelae of Zika virus infection are not well known. Recently, the World Health Organization changed the declaration of Zika as a public health emergency and designated the viral outbreak and related microcephaly clusters as a long-term program of work. This change indicates the urgent need to evaluate and document ophthalmic manifestations in patients for timely management of this disease. In addition, confirmation whether the public health problem in Brazil extends to other regions in South America is needed. OBJECTIVE To report the ocular manifestations of congenital Zika syndrome with microcephaly in Colombia and Venezuela. DESIGN, SETTING, AND PARTICIPANTS This prospective case series included 43 patients from 2 ophthalmic centers in Colombia and Venezuela who underwent evaluation from October 1, 2015, through June 30, 2016, and were clinically diagnosed with congenital Zika syndrome. Twenty patients were Hispanic; 13, African; 8, white; and 2, Native American. INTERVENTIONS Ophthalmic and systemic evaluations and serologic testing were performed on all infants. Patients underwent external ocular examination and dilated ophthalmoscopy. Serologic testing ruled out toxoplasmosis, rubella, cytomegalovirus, syphilis, and human immunodeficiency virus. MAIN OUTCOMES AND MEASURES Ophthalmic manifestations of congenital Zika syndrome. RESULTS Of the 43 patients included in this series (28 female and 15 male), the mean (SD) age at examination was 2.1 (1.5) months. The mothers of all the children had no ophthalmic findings and did not report ocular symptoms during pregnancy. All patients had bilateral ophthalmic manifestations. Optic nerve findings included hypoplasia with the double-ring sign, pallor, and increased cup-disc ratio in 5 patients (11.6%). Macular abnormalities included mild to severe pigment mottling in 27 patients (63%) and lacunar maculopathy in 3 (6.9%). Chorioretinal scarring was present in 3 patients (7%). Eleven patients (26%) had a combination of lesions in the posterior pole. Five patients (12%) were diagnosed with congenital glaucoma, characterized by the clinical triad of epiphora, photophobia, and blepharospasm; increased intraocular pressure; corneal clouding at birth; and buphthalmos. These data reveal that 12%(95%CI, 5%-24%) of cases of congenital Zika with microcephaly had anterior segment abnormalities and 88%(95%CI, 76%-94%) had important macular and optic nerve abnormalities. The visual sequelae of these ophthalmic manifestations remain unknown. CONCLUSIONS AND RELEVANCE Congenital Zika syndrome in the current study had severe ocular abnormalities, and all patients had bilateral involvement. Ocular findings were focal macular pigment mottling, chorioretinal atrophy with a predilection for the macular area, congenital glaucoma and optical nerve hypoplasia, and optic disc abnormalities. Ophthalmic examination is recommended in patients with congenital Zika syndrome

Conducting Research with Stigmatized Populations: Practices, Challenges, and Lessons Learned

Conducting research with communities who are at risk of being stigmatized can be a challenging endeavor. It is often difficult to reach and recruit individuals for research purposes regarding a stigmatized condition or situation. Yet, researchers in our field have recognized the importance of work in this area and have individually developed a range of strategies to reach, recruit, and work with these populations. This workshop will invite researchers and practitioners to present, discuss, and compare strategies and experiences when working with stigmatized communities in the context of the ever-evolving nature of technology. The outcomes of the workshop will include an outline for an article that will summarize the strategies and practices discussed as well as identify the approaches that have led to the best outcomes across different populations

Interoperabilidad en Sistemas Domóticos Mediante Pasarela Infrarrojos-ZigBee

La domótica consiste en la aplicación de técnicas provenientes de la automática industrial al hogar con objeto de ofrecer servicios que aporten, entre otras cosas, confort, seguridad y eficiencia energética a los usuarios. Hasta el momento la penetración de dichas técnicas en los hogares ha sido reducida. Una de las razones fundamentales de esta lenta transposición de técnicas de control al hogar es la dificultad de integración entre los diferentes sistemas presentes en el hogar. En este artículo se presenta un desarrollo encaminado a mejorar la integración de los sistemas domóticos con aquellos dispositivos que sean controlables mediante infrarrojos. En concreto se ha desarrollado una pasarela inalámbrica que permite a una red domótica el envío de tramas de infrarrojos. De esta manera se posibilita un despliegue rápido y económico de los nodos que sean necesarios para integrar dispositivos tales como los sistemas de aire acondicionado en una red domótica.Ministerio de Industria, Turismo y Comercio MITC-09-TSI-020100-2009-359Ministerio de Educación DPI2008-05818Junta de Andalucía TEP0272

Evolution of Class IITCPgenes in perianth bearing Piperales and their contribution to the bilateral calyx in Aristolochia

[EN] Controlled spatiotemporal cell division and expansion are responsible for floral bilateral symmetry. Genetic studies have pointed to class II TCP genes as major regulators of cell division and floral patterning in model core eudicots. Here we study their evolution in perianth-bearing Piperales and their expression in Aristolochia, a rare occurrence of bilateral perianth outside eudicots and monocots. The evolution of class II TCP genes reveals single-copy CYCLOIDEA-like genes and three paralogs of CINCINNATA (CIN) in early diverging angiosperms. All class II TCP genes have independently duplicated in Aristolochia subgenus Siphisia. Also CIN2 genes duplicated before the diversification of Saruma and Asarum. Sequence analysis shows that CIN1 and CIN3 share motifs with Cyclin proteins and CIN2 genes have lost the miRNA319a binding site. Expression analyses of all paralogs of class II TCP genes in Aristolochia fimbriata point to a role of CYC and CIN genes in maintaining differential perianth expansion during mid- and late flower developmental stages by promoting cell division in the distal and ventral portion of the limb. It is likely that class II TCP genes also contribute to cell division in the leaf, the gynoecium and the ovules in A. fimbriata.We thank Anny Garces Palacio, Sarita Munoz, Pablo Perez-Mesa (Universidad de Antioquia, Colombia), Cecilia Zumajo-Cardona (The New York Botanical Garden), Ana Berbel and Clara Ines Ortiz-Ramirez (Instituto de Biologia Molecular y Celular de Plantas, CSIC-UVP, Valencia, Spain) for photographs and assistance during laboratory work.

Control de robot manipulador mediante Wiimote

XXVIII Jornadas de Automática 5-7 de septiembre de 2007 Universidad de HuelvaLa intervención de operadores humanos continúa siendo necesaria para tareas de control. La formación de los operadores hasta que alcanzan un grado de destreza adecuado para llevar a cabo su labor exige una inversión de recursos que en muchos casos no es despreciable. Por tanto, son deseables dispositivos de control que simplifiquen la interacción entre el hombre y la máquina, de modo que las curvas de aprendizaje para los operadores sean lo más sencillas posibles. Justo esto es lo que se pretende con el Wiimote, la interfaz de control de Nintendoc para su última consola de sobremesa. En este artículo se muestran las posibilidades de control de este dispositivo y se presenta una aplicación para el control con el mismo de un robot manipulado
