An algorithm for convex parametric QPs is studied. The algorithm explores the parameter space by stepping a sufficiently small distance over the facets of each critical region and thereby identifying the neighboring regions. Some conjectures concerning this algorithm and the structure of the solution of a parametric QP are presented.

Patient pathways are a means to structure the care process for patients with complex and long-term diseases in integrated networks. Simultaneously, they have stronger emphasis on patient perspective engagement than related pathway concepts. Still, there no common mechanisms concepts models. This paper therefore explores state-of-the-art of tools as well evidence their effectivity feasibility, p...

– Quasi-one-dimensional superconductors or nanowires exhibit a transition into a nonsuperconducting regime, as their diameter shrinks. We present measurements on ultrashort nanowires (∼40–190 nm long) in the vicinity of this quantum transition. Properties of all wires in the superconducting phase, even those close to the transition, can be explained in terms of thermally activated phase slips. ...

در دهه ی اخیر مخابرات نوری فضای آزاد جذابیت زیادی پیدا کرده است و کاربردهای بالقوه ای برای این تکنولوژی پیشنهاد شده است. از بین مدولاسیون های دیجیتال نظیر MDPIM , DPIM , PPM , OOK که در مخابرات نوری فضای آزاد به کار می روند، DPIM مزیت هایی در زمینه ی ظرفیت انتقال، پهنای باند مورد نیاز، توان مصرفی مورد نیاز و طراحی آن دارد. مدولاسیون DPIM با حذف اسلات های خالی ("صفر") که در هر سمبلPPM بلا استفاد...

In practice, we use SQP to solve (*), finding z⋆ x; θ via a solution for fast argmin differentiation in QPs [3] and then taking derivatives through the quadratic approximation at this optimum. Technical Challenge: Argmin Differentiation We outperform both traditional model learning and model-free policy optimization in terms of task cost, the objective of actual interest in the closed-loop system.

Tremor is the most common movement disorder encountered during daily neurological practice. Tremor in the upper limbs causes functional disability and social inconvenience, impairing daily life activities. The response of tremor to pharmacotherapy is variable. Therefore, a combination of drugs is often required. Surgery is considered when the response to medications is not sufficient. However, ...

Recent technological advances have enabled the creation of networks of sensor devices. These devices are typically equipped with basic computational and communication capabilities. Systems based on these devices can deduce high-level, meaningful information about the environment that may be useful to applications. Due to their scale, distributed nature, and the limited resources available to se...

The finite-genus solutions for the Hirota's bilinear difference equation are constructed using the Fay's identities for the θ-functions of compact Riemann surfaces. In the present work I want to consider once more the question of constructing the finite-genus solutions for the famous Hirota's bilinear difference equation (HBDE) [1] which has been solved in [2] using the so-called algebraic-geom...

Dear Editor, Quadratic programming problems (QPs) receive a lot of attention in various fields science computing and engineering applications, such as manipulator control [1]. Recursive neural network (RNN) is considered to be powerful QPs solver due its parallel processing capability feasibility hardware implementation [2]. In particular, large number RNN models, gradient network, are proposed...

در سال‌های اخیر از اینورتر برای کنترل سرعت موتورهای القایی سه فاز به‌طور گسترده‌ای استفاده می‌شود. به منظور کلیدزنی ادوات نیمه‌هادی به‌کار رفته در اینورترهای قدرت از روش‌های گوناگونی از جمله مدولاسیون پهنای پالس استفاده می‌شود. تکنیک‌های مختلفی برای مدولاسیون پهنای پالس وجود دارد. در این مقاله سعی شده است تا تکنیک‌های مدولاسیون پهنای پالس سینوسی و بردار فضایی به‌طور کامل توصیف و با شبیه‌سازی ای...
