In power generation and other production settings, technological constraints force restrictions on the number of time-periods that a machine must stay up once activated, and stay down once deactivated. We characterize the polyhedral structure of a model representing these restrictions. We also describe a cutting-plane method for solving integer programs involving such min-up and min-down times ...
abstract in this thesis at first we comput the determinant of hankel matrix with enteries a_k (x)=?_(m=0)^k??((2k+2-m)¦(k-m)) x^m ? by using a new operator, ? and by writing and solving differential equation of order two at points x=2 and x=-2 . also we show that this determinant under k-binomial transformation is invariant.
Next generation fixed wireless networks are most likely organized in a mesh structure. The performance of these mesh networks is mainly influenced by the routing scheme and the channel assignment. In this paper, we focus on the routing and channel assignment in large-scale Wireless Mesh Networks to achieve a max-min fair throughput allocation. As most optimization approaches fail to optimize la...
key features covered by this talk are, choice of transducers and needles; patient positioning; joint injections and aspirations; tendon sheath injections; cyst aspirations; biopsies.
BACKGROUND Cryoballoon (CB) ablation is successful in eliminating atrial fibrillation (AF). PURPOSE The purpose of this study was to assess procedural efficacy and safety of CB ablation performed by a newly trained operator. METHODS Forty patients with documented paroxysmal AF (58 ± 11 years, 26 male) undergoing CB catheter ablation were prospectively enrolled. RESULTS Electrical pulmonar...
In this short note, we present some inequalities for relative operator entropy which are generalizations of some results obtained by Zou [Operator inequalities associated with Tsallis relative operator entropy, {em Math. Inequal. Appl.} {18} (2015), no. 2, 401--406]. Meanwhile, we also show some new lower and upper bounds for relative operator entropy and Tsallis relative o...
