Recent years have shown results in dictionary improvement by investigating the cosupport via the analysis-based cosparse model. In this paper we present a new cosparse learning algorithm for orthogonal dictionary blocks that provides significant dictionary recovery improvements and representation error shrinkage. Furthermore, we show the beneficial effects of using this algorithm inside existing methods based on building the dictionary as a structured union of orthonormal bases.","PeriodicalId":257135,"journal":{"name":"2015 19th International Conference on System Theory, Control and Computing (ICSTCC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116290874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The fields of application involve among others, the military as well as the medical industries. This paper presents the design of part of an exoskeleton aimed to enhance the performance of people that have had spinal injury or that suffer from some problem or pain in the lumbar area. An experimental platform was built that allows the wearer to perform his/her tasks without making a big effort that could cause pain or injuries in the lumbar zone. The experimental platform employs Pneumatic Artificial Muscles (PAM) as actuators because they are suitable for applications were force is required. However being these actuators highly nonlinear devices, the control as well as the electronics involved in the design of the experimental set up are not a simple tasks. The experimental set up presented here is a one degree of freedom device attached to the trunk of a user. To start with a PD controller was employed. This set up is part of a bigger project that considers a complete exoskeleton that involves the four limbs and the middle part of a human body. However this device can be used to assist, as mentioned before, people with problems in the lumbar area.","PeriodicalId":257135,"journal":{"name":"2015 19th International Conference on System Theory, Control and Computing (ICSTCC)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114394466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The model, based on mass balance considerations, consists in the coupling of two sub-models, namely a biological model and a chemical speciation model. The biological model allows the prediction of biomass, substrate and product concentrations, while the chemical speciation model is a computational package that quantitatively describes each molecular and ionic species of the system. There were investigated the sensitivities of the biomass, substrate and lactic acid equations to parameters, thus the most influential parameters being identified.","PeriodicalId":257135,"journal":{"name":"2015 19th International Conference on System Theory, Control and Computing (ICSTCC)","volume":"139 42","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120820390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Following the continuous process stability analysis, a closed-loop optimization of the bioethanol outflow rate using a model-free extremum-seeking algorithm is suggested.

The control strategies were simulated, using the model of an influent having loads corresponding to the real plant, for a dry regime, in open and closed loop.

In order to facilitate the transformation of the developed HPN model into models useful for supporting the design of control algorithms, a methodology to transform arcs in synchronization events is outlined.
