Balas","doi":"10.1109/AHS.2017.8046347","DOIUrl":"https://doi.org/10.1109/AHS.2017.8046347","url":null,"abstract":"Many control systems are inherently infinite dimensional when they are described by partial differential equations. Currently, there is renewed interest in the control of these kinds of systems, especially in the quantum information field. Since the dynamics of these systems will not be perfectly known, it is especially of interest to control these systems adaptively and even autonomously via low-order finite-dimensional controllers. In our work, we have developed direct model reference adaptive control and disturbance rejection with very low-order adaptive gain laws for infinite-dimensional systems on Hilbert spaces. Quantum Information Systems are fundamentally infinite dimensional. And the basic operations that can be performed on quantum systems to manipulate information are unitary quantum gates. Because of the nature of entanglement at the quantum level, these gates suffer from decoherence and cannot operate in a fully unitary way. It is also quite difficult to perform experiments that would identify all the parametric data needed to create precise models of a particular quantum system. Instead, direct adaptive control that is suited to infinite dimensional systems could provide a reduction in the decoherence and allow the quantum gates to function in a more idealized unitary way. This talk will focus on the effect of infinite dimensionality on the adaptive control approach and the conditions required for asymptotic stability with adaptive control. Then I would like to go on and consider some of the issues in the control of quantum information systems. The topics here may sound highly technical, but I hope to give you a version of them that will be reasonably accessible and will still remain as exciting and attractive to you as they are to me.","PeriodicalId":101545,"journal":{"name":"NASA/ESA Conference on Adaptive Hardware and Systems","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117004926","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}

This paper takes some steps toward the formal integration of Structure, Control, and Signal Processing designs. To integrate structure and control we employ the tensegrity structural paradigm. To integrate signal processing and control we employ the new work called Information Architecture, where the precisions and locations of all sensors and actuators are coordinated with the control design, which are all dictated by the closed loop performance requirements, including a cost constraint on the hardware. We assume that sensor or actuator costs are proportional to the precision of the instrument. The design constraints are: i) the cost of all sensors and actuators must be less than a specified budget, $, ii) the control energy must satisfy a specified upper-bound, U, iii) the closed loop performance must satisfy a specified covariance upper-bound, Y, of the output error, iv) adjustable parameters of the structure are coordinated with the joint structure/control design to achieve the required performance bounds, Y. Given a hardware budget $, and performance budgets U and Y, the paper shows what performance (Y) is achievable for a fixed cost $ and a fixed energy budget U. Alternatively, for a fixed performance and energy budget (Y, U) the paper shows the minimum hardware costs $ required to achieve this performance.","PeriodicalId":101545,"journal":{"name":"NASA/ESA Conference on Adaptive Hardware and Systems","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127810634","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}

Not only do the injured lose the ability to stand and walk (and sometimes move their arms), they suffer from additional injury-induced complications including loss of bladder and bowel control, decreased cardiovascular and pulmonary health, inability to regulate body temperature, and loss of muscle strength and bone density. The totality of the injury and its secondary dysfunctions makes daily activities of living a challenge. Because the median age of SCI in the U.S. is 32 years, SCI individuals amass an additional $1.4–$4.2 million in healthcare costs over their lifetimes. A team of researchers at Caltech, UCLA, and Univ. of Louisville have been developing new technologies and new therapies for motor complete SCI patients — those who have lost motor control below the level of their injury. The centerpiece of this approach is a multi-electrode array that is implanted over the lumbosacral spinal cord either in in the epidural space between the dura and the interior of the vertebral canal, or on the skin over this area. When this technology is coupled with locomotor training and drug therapy (when possible), SCI patients receiving this therapy can stand independently and make some voluntary movements (after being in a wheel chair for over 3 years). More importantly, they can expect to make useful gains in cardiovascular health, muscle tone, as well as improved autonomic function such as bladder, bowel, blood pressure, and temperature regulation. After first reviewing our clinical successes, this talk will focus on current research on new machine algorithms for automated tuning of the stimuli parameters.","PeriodicalId":101545,"journal":{"name":"NASA/ESA Conference on Adaptive Hardware and Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127749330","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}

Fixed-point word-length optimization is a well-known research area that aims to find the optimal trade-offs between accuracy and hardware cost in bitwidth allocation signals in fixed point circuits. This work proposes a methodology to combine word-length optimization with application-specific processor customization. The goal is to optimize the following parameters in the processor architecture: (1) datatype word-lengths, (2) size of register-files and (3) architecture of the functional units. Multi-level evolutionary algorithms are employed to perform the optimization. To facilitate evaluation, a new processor design environment was developed that supports necessary customization flexibility to realize and evaluate the proposed methodology. The experimental results show that for five evaluated benchmarks, the proposed methodology can reduce the number of consumed LUTs and flip-flops by an average of 11.9% and 5.1%, respectively, while reducing the latency by an average of 33.4%.","PeriodicalId":101545,"journal":{"name":"NASA/ESA Conference on Adaptive Hardware and Systems","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132492415","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 two fluids were kept at bay by the precipitation of iron minerals at the spring. It was in the mineral barriers that this free energy was first converted via a protometabolism to organic molecules. Thus, we can say that life hydrogenated, and still hydrogenates, carbon dioxide. Therefore, we may expect life to emerge on any wet and rocky world that has a partly carbon dioxide-rich ocean. One possible example is on Europa (see Figure). It should reveal itself either as whole cells or as bioorganic molecules that themselves are far-from-thermodynamic equilibrium.","PeriodicalId":101545,"journal":{"name":"NASA/ESA Conference on Adaptive Hardware and Systems","volume":"151 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116518825","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}
