In Anderson et al. (1975) the application of Tarski–Seidenberg decision theory (Tarski, 1951, Seidenberg, 1954) for the solution of the static output feedback stabilization problem for specific problems was first proposed. The general static output feedback stabilization problem is one of the most important open problems in feedback design. The problem can be stated mathematically as follows: f...

BACKGROUND Known causes of superficial punctuate keratopathy (SPK) in children include entropion, viral infection, blepharokeratoconjunctivitis (BKC), and toxicity of eye drops. However, there are some SPK patients whose causes could not be identified well. Herein, we describe the history, diagnosis, treatment, and prognosis of a rare case. CASE PRESENTATION To report a case of superficial pu...

In this paper, we consider two problems which can be posed as spectral radius minimization problems. Firstly, we consider the fastest average agreement problem on multi-agent networks adopting a linear information exchange protocol. Mathematically, this problem can be cast as finding an optimal W ∈ Rn×n such that x(k + 1) = Wx(k), W1 = 1, 1TW = 1T and W ∈ S(E). Here, x(k) ∈ Rn is the value poss...
