Title: “Tackling Health Opportunities through Mobile Application Solutions”

Date: Friday, July 26, 12:00 a.m.

Localication: CIO Seminar Room (Torretamarit Building)

Abstract. Mobile health (mHealth) has experienced significant growth. This is attributable to three key factors: 1) the need for a disruptive solution to challenge the spiralling cost of healthcare, 2) the growth and maturity experienced in mHealth i.e. wireless connectivity and 3) the need for personalised medicine driven by the increased availability of novel, real-time data streams. This presentation considers the motivation and goals behind five funded research projects in the health domain. This research agenda is broadly underpinned by five key themes: 1) analysis, design and development of mobile solutions, 2) user intention to participate/use these solutions, 3) user experience (UX) design methods, 4) the need for a robust small data solution as a prerequisite for a “big health data” opportunity and 5) technology choices in mobile application development. These studies were undertaken to develop mobile applications to support capture, storage, analysis and visualisation of health related data/information. The applications developed offer a unified view of information to support users’ decision making requirements in real-time. Thisresearch is concerned with the user experience (UX) of the application (app) and/or the information (content) and how it is consumed. Intuitiveness and user learnability have been assessed along with stakeholder readiness.

Title: “Modelling Environmental Inefficiency under a Quota System”

Date: Tuesday, July 16, 12:30 a.m.

Localication: CIO Seminar Room (Torretamarit Building)

Abstract. This paper introduces the methodology necessary to evaluate inefficiency of regulated decision making units that operate under quotas through Data Envelopment Analysis (DEA), accounting for both quotas’ restrictions and negative environmental externalities of production. Three technical inefficiency measures are proposed: inefficiency in the production of marketed output, environmental inefficiency, and inefficiency with quotas. It is then shown how to aggregate these measures in order to obtain indicators of overall performance. The new approach is illustrated through a numerical example that uses real data available for the European Union dairy sector. The results show that considerable differences in inefficiencies could be found when quotas restrictions are accounted for in the model than in the model without quota imposition, indicating that not accounting explicitly for quotas when measuring performance in regulated sectors may lead to a not accurate estimation of firms’ technical inefficiency.

Title: “Approach schemes for some Infinite Linear Programming problems”

Date: Monday, July 17, 12:30 a.m.

Localication: CIO Seminar Room (Torretamarit Building)

Abstract. In this talk we will present approximation schemes for problems of Infinite Linear Programming. Some examples of problems brought to Infinite Linear Programming are: the Problem of Mass Transfer, Semi-Infinite Linear Programming, the Transboundary Problem and the Markov Control Problem. One of the most important techniques of Infinite Linear Programming is the approach theory, for which it is necessary to look for conditions under which there are solutions for a particular problem. Hernández-Lerma and Lasserre propose a general approximation scheme for infinite linear programs, which requires two procedures: aggregation-relaxation of the constraints and internal approximation of the variable of interest. Applying the above, the Infinite Linear Programming problem is discretized. In this talk, we will show the computational implementation of the scheme proposed by Hernández-Lerma and Lasserre, to the Problem of Mass Transfer of Monge-Kantorovich. We will end the talk with an approximation scheme for the Markov Control Problem with discount criteria. Hernández-Lerma and Lasserre prove that the Markov Control Problem with discount criteria is equivalent to an Infinite Linear Programming problem when using occupation measures, using the equivalent linear programming problem and under the proposed algorithm for the Transfer Problem of Masses of Monge-Kantorovich proposed by Gabriel-Argüelles, López-Martínez and González-Hernádez we will show an approximation scheme in compact spaces.
