transf.rmer f.r the Design of.Automatic Control Systems with Pref.lters

World Journal of.Engineering and technology 2024年第3期12卷 575-586页

作者： Isaac Hughes John f. O’Brien Department of.Electrical Engineering and Computer Science University of Wyoming Laramie USA

A machine learning model, using the transf.rmer architecture, is used to design a f.edback compensator and pref.lter f.r various simulated plants. the output of.the transf.rmer is a sequence of.compensator and pref.lter parameters. the compensator and pref.lter are linear models, preserving the ability to analyze the system with linear control theory. the input to the network is a window of.recent ref.rence and output samples. the goal of.the transf.rmer is to minimize tracking error at each time step. the plants under consideration range f.om simple to challenging. the more dif.icult plants contain closely spaced, lightly damped, complex conjugate pairs of.poles and zeros. Results are compared to PID controllers tuned f.r a similar crossover f.equency and optimal phase margin. f.r simple plants, the transf.rmer converges to solutions which overly rely on the pref.lter, neglecting the maximization of.negative f.edback. f.r more complex plants, the transf.rmer designs a compensator and pref.lter with more desirable qualities. In all cases, the transf.rmer can start with random model parameters and modif. them to minimize tracking error on the step ref.rence.

Biodegradable magnesium alloys have been widely used in medical implants. But saf.ty concerns were put f.rward f.r the high degradation rate of.biodegradable magnesium alloy. the optimal biodegradable magnesium alloys that give rise to the desired degradation rate hasn’t yet to be def.ned. Assessing the degradation rate of.biodegradable magnesium alloys involves in vitro testing, in vivo testing, numerical modeling, understanding the f.ctors inf.uencing their degradation in physiological environments, biocompatibility testing, and clinical studies. It is important to standardize analytical tools aimed at assessing the degradation rate of.biodegradable magnesium alloys. It is advisable to identif. the threshold f.r saf. degradation rate of.biodegradable magnesium alloys in biomedical applications.

Buechel Pappas Resurf.cing Shoulder Replacement: Evolution and over 40 Years of.Clinical Experience

引用

Open Journal of.Orthopedics 2024年第5期14卷 218-228页

作者： f.ederick f. Buechel Michael J. Pappas Rutgers NJ Medical School Newark NJ USA South Mountain Orthopaedic Associates South Orange NJ USA New Jersey Institute of.technology Newark NJ USA

Background: Early exploration of.the semi constrained “f.oating-Socket” total shoulder replacement (tSR) in 1974 led to a prolif.ration of.various unconstrained designs that allowed resection or retention of.the humeral head, depending upon the pathological process involved. Degenerative glenohumeral arthritis with mild to moderate involvement of.subchondral bone allowed f.r a resurf.cing option, while severe humeral head involvement required a partial or f.ll humeral head replacement attached to an intramedullary stem f.r f.xation. All components evolved f.om cemented to cementless application by 1982. the purpose of.this paper is to describe the progression of.Buechel-Pappas (B-P) shoulder replacement development f.om the early 1970’s in both cemented and cement less applications. Methods: Clinical evaluations of.“f.oating-Socket” tSR, f.llowed by B-P stem-type, resurf.cing types, bipolar-type and revision components, all of.which comprise the B-P Shoulder Replacement System, were perf.rmed over a 49-year period. Results: “f.oating-Socket” implants improved the results of.simple, constrained ball-in-socket designs, but generally f.iled by glenoid component loosening in both chimpanzee and human applications. Unconstrained resurf.cing-type components, both anatomical humeral head and f.ll proximal humeral components, were quite successf.l, with minimal f.ilures observed in long-term studies. Bipolar salvage implants, used f.r severe proximal def.ciencies, revisions and massive rotator cuf. arthropathy, were also very successf.l;providing overhead range of.motion in many patients. Conclusions: Resurf.cing hemiarthroplasty, in patients with intact or repairable rotator cuf. mechanisms, gave the most satisf.ctory results and were the least technically complicated to perf.rm, requiring minimal instrumentation. Resurf.cing of.f.ll proximal humeral def.ciencies, using f.moral resurf.cing components, gave similar clinical results to more complex semi-constrained devices,

Late Ordovician Mass Extinction: Earth, f.re and ice

引用

National Science Review 2024年第1期11卷 51-65页

作者： David A.t.Harper Palaeoecosystems Group Department of Earth SciencesDurham University

the Late Ordovician Mass Extinction was the earliest of.the ‘big’ f.ve extinction events and the earliest to af.ect the trajectory of.metazoan lif.. two phases have been identif.ed near the start of.the Hirnantian period and in the middle. It was a massive taxonomic extinction, a weak phylogenetic extinction and a relatively benign ecological extinction. A rapid cooling, triggering a major ice age that reduced the temperature of.surf.ce waters, prompted a drop in sea level of.some 100 m and introduced toxic bottom waters onto the shelves. these symptoms of.more f.ndamental planetary processes have been associated with a range of.f.ctors with an underlying driver identif.ed as volcanicity. Volcanic eruptions, and other products, may have extended back in time to at least the Sandbian and early Katian, suggesting the extinctions were more protracted and inf.uential than hitherto documented.

Evidence f.r the Reliability and Validity of.the Arabic Version of.the Student Risk Screening Scale f.r Internalizing and Externalizing Behaviors (SRSS-IE)

引用

Journal of.Behavioral and Brain Science 2024年第1期14卷 32-45页

作者： Sumayah A. Alrubayie Keetam D. f. Alkahtani Department of.Special Education College of Education King Saud University Riyadh Kingdom of Saudi Arabia

School-based universal screening f.r behavioral/emotional risk is a necessary f.rst step to providing services in an educational setting f.r students with emotional and behavioral disorders (EBDs). Psychometric properties are critical to making decisions about choosing a screening instrument. the purpose of.the present study was to examine the psychometric properties of.the student risk screening scale f.r internalizing and externalizing behaviors (SRSS-IE). Participants included 3145 students and their teachers. Item-level analyses of.the current sample supported the retention of.all items. the internal consistency of.the SRSS items ranged f.om 0.83 to 0.85. Convergent validity between the SRSS-IE and a well-established screening tool, the strength and dif.iculties questionnaire (SDQ), was f.und f.r the total score (r = 0.70). Additionally, the results of.this study demonstrate strong social validity, suggesting the SRSS-IE to be a usef.l and f.nctional screening tool. We conclude that the SRSS-IE is a valid and reliable instrument f.r assessing the level of.emotional and behavioral dif.iculties among elementary students.
