Dynamic Modeling and Control of Quad Rotor

Abstract This paper presents a nonlinear compensation technique to solve the trajectory tracking problem for a quadrotor. The kinematics and dynamic equations are obtained using Lagrange –Euler principle. The proposed control algorithm is robust to pay load variations even at high speed or low speeds. The controller can compensate the complex dynamics and also other external disturbances. The torque demanded for the particular motion and maximum payload is computed and it is very low compared with other control techniques. The simulation results demonstrate the proposed control algorithm can track the desired trajectory as well as control the attitude levels and also the thrust force is reduced.
An improvement of performance to layered index-less indexed flash codes

Index-less indexed flash code (ILIFC) has excellent worst-case performance. The layered ILIFC (L-ILIFC) method proposed by Suzuki and Wadayama enables a change of indices when the layer level of charge increases in a sub-block of memory cells. L-ILIFC allows a larger average number of rewrites than ILIFC. Kuribara and Fujisawa developed the L-ILIFC to improve the average-case performance. We call it change index L-ILIFC (CIL-ILIFC). In this paper, we propose an improved rewriting strategy for L-ILIFC. The proposed method enables a sub-block to hold multiple indices to increase the number of rewrites between block erasures. Simulation results shows that the average number of rewrites of the proposed method is improved compared with the conventional L-ILIFC.
A Scalable and Cooperative Caching Scheme in a Distributed VOD System

In distributed streaming media server clusters, by adopting cooperative caching technique, the free cache memory of all the servers in the cluster can be used more efficiently. It will help raise the hit rate of the cache and reduce disk accesses, resulting in the improvement of the overall throughput of cluster. In this paper, a novel distributed caching model called Scalable and Cooperative Caching (SCC) is presented. SCC makes use of each server to perform the caching task and redirects the request to the proper server in the cluster to make the cache scheme more efficient. This way, SCC can provide high scalability and throughput in clustered servers with a reasonably small amount of communication among hosts. Simulation results show that SCC is an effective caching strategy providing significant performance gains in clustered video servers.
Approximate Entropy as a Measure of Regularity in Hormone Series

1. Introduction Hormones, such as luteinizing hormone (LH), are secreted into the blood in short bursts, called pulses, and removed by a decay process. Using hormone assays from blood samples obtained at equally spaced intervals, investigators study secretion characteristics such as pulse frequency and amplitude to learn whether various diseases affect hormone secretion. Approximate entropy (ApEn) has been used to assess regularity in a series. Although it is not specifically tailored to the identification and characterization of pulses (Pincus and Keefe 1992), the authors state that ApEn evaluates both dominant and subordinate patterns in data and therefore detects differences in pulsatile series even when pulse frequency and height do not differentiate between the secretion patterns. ApEn does distinguish between complex mathematical systems that can generate hormone data (Pincus, 1994), but little has been studied about the sensitivity of ApEn to randomness in the main pulse characteristics (timing, mass, duration, and noise). We were interested in assessing whether ApEn was sensitive to timing, mass, and duration. We generated simulated data with fixed pulse characteristics and then added random effects to the timing, mass, and duration parameters. We studied combinations of fixed and random characteristics under various model assumptions (longer vs. shorter half-life, slow vs. rapid pulsing, and noise vs. no-noise) to assess which parameter characteristics cause changes in the ApEn statistic. Since ApEn is being used to characterize the regularity of secretion we also wanted to assess whether conclusions made in peripheral blood, the samples collected in human studies, could be used to draw conclusions about the regularity of secretion closer to the source. We calculated the ApEn statistics for LH data collected in the portal and peripheral blood in six ewes. This enables us to evaluate the influence of hormone dispersion in the peripheral blood on the ApEn statistic.
THROOM : Running POSIX Multithreaded Binaries on a Cluster

Most software distributed shared memory systems (SW-DSMs) lack industry standard interfaces that limit their applicability to a small set of shared-memory applications. In order to gain general acceptance, SW-DSMs should support the same look-and-feel of shared memory as hardware DSMs. This paper presents a runtime system concept that enables unmodified POSIX P1003.1c (Pthreads) compliant binaries to run transparently on clustered hardware. The key idea is to extend the single process model of multi-threading to a multi-process model where threads are distributed to processes executing in remote nodes. The distributed threads execute in a global shared address space made coherent by a fine-grain SW-DSM layer. We also present THROOM, a proof-of-concept implementation that runs unmodified Pthread binaries on a virtual cluster modeled as standard UNIX processes. THROOM runs on top of the DSZOOM fine-grain SW-DSM system with limited OS support.
Rozhdestvensky "Theory of Rhetoric" as the Foundation for studies of Language in the Media

Russian Evolution:Russian Reflections Date: 21st October 2017 Saturday Part of a one day conference at the Institute of English Studies with International Speakers on the work of Professor Yuri Rozhdestvensky (1926-1999): his Contribution to Linguistics, Rhetoric, Communication Theory, Semiotics, Poetics and Narratology. The work of Professor Yuri Rozhdestvensky (formerly of the Moscow State Lomonosov University, Moscow) is almost completely unavailable in English. This conference provides analysis of two parts of his book, General Philology – the Introduction and Chapter Five entitled ‘Printed Literature’ (this work is translated for the first time by Paul and Elena Richard and is now available on: https://sas-space.sas.ac.uk ) Analysis of this translated work reveals Rozhdestvensky’s lifelong interest and commitment to a theory of culture as a historical, linguistic, philological and semiotic development. The conference highlights the analysis of poetics in Chapter Five with reference to Professor V. V. Vinogradov whose work is also largely unavailable in English translation. The use of codes, as defined by Roman Jakobson, provides the theory for the provision of connections between Rozhdestvensky’s analysis of culture, poetics, linguistics, semiotics and philology whereby his work can be understood by those unfamiliar with his theoretical position. This includes special emphasis on Vinogradov’s theory of the image of the author. The necessary component of diachrony in Rozhdestvensky’s work and the links to the discipline of Narratology are highlighted. It is concluded that Rozhdestvensky has unique and original contributions to make to academic studies through his particular understanding of a Theory of Culture.
A framework for monitoring and security authentication in cloud based on Eucalyptus

Since the cloud computing was proposed, the research of cloud instantaneously swept the world and all kinds of cloud products have appeared in public eyes. But if the cloud platform security is not guaranteed, companies or individuals will not run and store their own data in the cloud, especially since the Hollywood nude-picture scandal event put the cloud computing to the point of a struggle. So how to put these cloud product promotion out and make interest to the company becomes the company's biggest problem, and the credible cloud's service has become an urgency to implement. In this paper, we are concerned with trust in the cloud computing. Paper mainly launches the discussion from the application layer and infrastructure layer. The monitoring system collects data from cloud system real time, and makes the corresponding judgment according to the analysis results. At the same time, the system will report the data to the third party to record and modify the system rules timely. By these means, the cloud system can improve the stability of the service and make it more credible.
Ependymoma With Cartilage Formation: A Case Report

OBJECTIVE: The presence of cartilage and bone in a glial tumor is most unusual. Several mechanisms have been proposed to explain this condition. In some cases, there is a fibrous capsule between tumor tissue and the cartilaginous area together with glial fibrillary acidic protein negativity in cartilage cells; in others, there is no fibrous capsule between cartilage cells and tumor tissue, and the cartilage cells are glial fibrillary acidic protein positive. CASE REPORT: A 56-year old female with an ependymoma containing a cartilaginous area is reported. The patient had been irradiated 8 years ago. The mechanisms of the occurrence of cartilage in gliomas are reviewed, and the probable effects of irradiation on this condition are discussed. RESULTS: In our case, there was no fibrous capsule between the ependymoma and the cartilaginous tissue, and the cartilage cells were glial fibrillary acidic protein immunopositive. CONCLUSION: In this case, it was considered that the cartilage formation resulted from the transformation of neuroepithelial cells to mesenchymal tissue because of the positive response of cartilage cells to glial fibrillary acidic protein and the lack of a fibrous capsule around the cartilaginous area.
Using Latent Profile Analysis to Identify Noncognitive Skill Profiles Among College Students

ABSTRACT Most research examining the relationship between noncognitive variables and academic performance has tended to focus on developing linear prediction models. However, a more holistic understanding of academic success can be achieved by examining the noncognitive profiles of students and their relationship with academic outcomes. In the present study, we used latent profile analysis to explore the noncognitive profiles of 5,120 college students. To better understand the nature of the profiles, the effect of covariates on class membership was examined. Results indicated that there were 6 latent profiles underlying the noncognitive skills of college students in our sample and that profile membership was associated with different collegiate grade point average levels. Our results have practical implications for the development of interventions intended to improve academic performance, which may be customized toward the specific needs of students presenting with diverse profiles.
The Roles of Amino Acids in Milk Yield and Components

Unlike the situation in monogastric species (Fuller et al., 1989), it has proven more difficult to predict with accuracy the amino acid (AA) requirements of ruminants for growth and milk production. The current NRC publications for dairy and beef cattle recognise this, and do not explicitly allow for diets to be balanced for essential (EAA) or limiting AA contents, except to recommend a ratio of 3:1 lysine to methionine in metabolizable protein (NRC 2000, 2001). With greater pressures being placed on dairy and beef production to reduce nitrogen wastes and the dairy industries desire to manipulate milk components to meet market demands, the need is there to define not just the limiting AAs, but the general requirement for all AA for production. Current feeding schemes sub-divide EAA requirements into net requirements for maintenance functions, i.e., the first priority, and for growth, lactation and/or reproduction. Therefore, the metabolizable protein requirement reflects only the roles AA serve as precursors for synthesis of proteins, e.g. muscle, milk caseins, conceptus. Conceptually, this approach is satisfactory since a major component of the metabolizable protein prediction will largely be determined from the AA composition of endogenous protein losses, and that needed for net synthesis of muscle, milk and fetal tissue proteins. Where there is less of a conceptual basis and agreement are the conversion or “efficiency” factors used to partition AA in the metabolizable protein to the various fates. It could be argued, therefore, that defining the basis of the “inefficiency” portion of the conversion factors is a goal that holds much greater potential for improving production and predictions than determining the pattern of limiting AA.
Project Summary: quantizing Schur functors

Geometric complexity theory (GCT) is an approach to P vs. NP and related problems in complexity theory using algebraic geometry and representation theory. A fundamental problem in representation theory, believed to be important for this approach, is the Kronecker problem, which asks for a positive combinatorial formula for the multiplicity gλμν of an irreducible representation Mν of the symmetric group in the tensor product Mλ ⊗Mμ. Blasiak, Mulmuley, and Sohoni have been developing an approach to this problem using quantum groups and canonical bases. The main focus of this proposal is to push this approach further. Canonical bases were first defined by Kazhdan and Lusztig through their study of singularities of Schubert varieties. Of particular interest for this project is their remarkable ability to connect combinatorics and representation theory. For instance, canonical bases beautifully connect the RSK correspondence with quantum Schur-Weyl duality, give a Littlewood-Richardson rule for all types, and have been used by Blasiak to explain the appearance of the combinatorial operations cyclage and catabolism in the graded characters of Garsia-Procesi modules. The nonstandard quantum group and nonstandard Hecke algebra were defined by Mulmuley and Sohoni to study the Kronecker problem. Recently, Mulmuley, Sohoni, and Blasiak have obtained the beginnings of a theory of canonical bases for these nonstandard objects. They construct a canonical basis of a certain representation of the nonstandard quantum group and use this to solve the Kronecker problem in the case of two two-row shapes. The Uq(sl2)-graphical calculus is used to organize and count the resulting crystal components, which is believed to be the beginnings of a new kind of graphical calculus in this setting. Blasiak, together with Mulmuley, Sohoni, and others, plans to push this approach further, in the following ways.

This paper presents an example of a PID controller applied to a 2-dimensional rotorcraft landing gear with two DOF (degrees of freedom), as well as the design of the landing gear dynamic model. The focus of this work is to maintain the landing spot to prevent the landing gear from skidding sideways on the ground, while adapting to different ground conditions. A nonlinear model for the landing gear dynamics formulated by solving Lagrange equation, is described in detailed, as well as the angle generation equations to provide reference signal to the system. The simulation results based on different surface conditions are presented.
H9N2 influenza A viruses from poultry in Asia have human virus-like receptor specificity.

H9N2 influenza A viruses are currently widespread in chickens, quail, and other poultry in Asia and have caused a few cases of influenza in humans. In this study, we found that H9N2 viruses from Hong Kong live bird markets have receptor specificity similar to that of human H3N2 viruses. In addition, the neuraminidase of poultry H9N2 viruses has mutations in its hemadsorbing site, a characteristic resembling that of human H2N2 and H3N2 viruses but differing from that of other avian viruses. Peculiar features of surface glycoproteins of H9N2 viruses from Hong Kong suggest an enhanced propensity for introduction into humans and emphasize the importance of poultry in the zoonotic transmission of influenza viruses.

Relationship violence was never on my radar screen . " (1) --Sharon Love, Yeardley's Mother In the spring of 2010, Yeardley Love was enjoying her final semester at the University of Virginia, where she had dreamed of attending school her whole life. Yeardley embraced her time in college to the fullest, joining a sorority and playing on the women's lacrosse team. The shock and horror Yeardley's loved ones experienced upon learning that she was beaten to death by her ex-boyfriend just three weeks shy of her graduation is unimaginable. Her story, however, is all too common. (2) On Thanksgiving of 2014, Shannon Jones, a senior at Cornell University, was strangled to death by her boyfriend. (3) The very next day, Nadia Ezaldein, a law student at the University of Chicago, was shot and killed by her ex-boyfriend. (4) That same year, Cecilia Lam, a student at San Francisco State University, (5) and Diamoney Greene, a student at the University of South Carolina, (6) were also killed by intimate partners. The Centers for Disease Control defines intimate partner violence as "physical violence, sexual violence, stalking and psychological aggression. by a current or former intimate partner. " (7) Reports indicate that more than three women are murdered by husbands or boyfriends each day. (8) Although high-profile stories like these have sent Shockwaves through college communities, violence by intimate partners is nonetheless largely overlooked in the college and university setting. …
The vehicle rescheduling problem: Model and algorithms

When a vehicle on a scheduled trip breaks down, one or more vehicles need to be rescheduled to serve the customers on that trip with minimum operating and delay costs. The problem of reassigning vehicles in real‐time to this cut trip as well as to other scheduled trips with given starting and ending times, is referred to as the vehicle rescheduling problem (VRSP). This paper considers modeling, algorithmic, and computational aspects of the single‐depot VRSP. The paper formulates a model for this problem and develops several fast algorithms to solve it, including parallel synchronous auction algorithms. The concept of the common feasible network (CFN) is introduced to find a good set of initial “prices” for speeding up the auction algorithm. Computational experiments on randomly generated problems are described. Computational results show that, for small problems, all of the developed algorithms demonstrate very good computational performances. For large problems, parallel CFN‐based auction algorithms provide the optimal solution with much smaller computation times. © 2007 Wiley Periodicals, Inc. NETWORKS, Vol. 50(3), 211–229 2007
Microbial degradation of complex carbohydrates in the gut

Bacteria that colonize the mammalian intestine collectively possess a far larger repertoire of degradative enzymes and metabolic capabilities than their hosts. Microbial fermentation of complex non-digestible dietary carbohydrates and host–derived glycans in the human intestine has important consequences for health. Certain dominant species, notably among the Bacteroidetes, are known to possess very large numbers of genes that encode carbohydrate active enzymes and can switch readily between different energy sources in the gut depending on availability. Nevertheless, more nutritionally specialized bacteria appear to play critical roles in the community by initiating the degradation of complex substrates such as plant cell walls, starch particles and mucin. Examples are emerging from the Firmicutes, Actinobacteria and Verrucomicrobium phyla, but more information is needed on these little studied groups. The impact of dietary carbohydrates, including prebiotics, on human health requires understanding of the complex relationship between diet composition, the gut microbiota and metabolic outputs.
Magno: An Application for Detection of Dyslexia - Dyslexia and Interface Design

Dyslexia is a disability that has accumulated more and more attention over the latest years. Being able to detect dyslexia early on is vital for decreasing the negative effects dyslexia has on people diagnosed with this disability. This master’s thesis deals with creating a graphical user interface of an existing application meant to be used as a screening tool in the process of detecting dyslexia. This is done by identifying a target user group, creating and testing prototypes, and implementing a finished design. The result of this process has been an application with a fully functional graphical user interface (GUI). The GUI has a System Usability Scale (SUS) score of 92.7, and increased usability compared to the original application. This master’s thesis has provided this application with a user interface that allows anyone with basic reading skills to test themselves for a risk of having dyslexia. Hopefully, when this application is deployed, the average age of dyslexia detection will be lowered significantly, with the help of our user interface design.
Cognitive Rhythms Reluctantly Revisited

In response to the Power (1983) - Beattie (1984) controversy, a more general critique of the construct of cognitive rhythms is presented. It is argued that the term itself is a misnomer, that the relevance of articulation rate has been neglected, that fluent and hesitant phases of cognitive rhythms have been assessed both subjectively and intuitively, that the speech-production model underlying the concept is simplistic, and that the empirical evidence is based on an extraordinarily small corpus which has been described inadequately in the research literature.
