Non-homogeneous BVPs for second-order symmetric Hamiltonian systems by Chen Yingying, Dong Yujun, Wang Baiqian

“…By making use of Bolle’s method, we show that the following problem has infinitely many solutions: x¨+V′(x)=0,x(0)cosα−x˙(0)sinα=x0,x(1)cosβ−x˙(1)sinβ=x1,\begin{array}{rcl}\ddot{x}+{V}^{^{\prime} }\left(x)& =& 0,\\ x\left(0)\cos \alpha -\dot{x}\left(0)\sin \alpha & =& {x}_{0},\\ x\left(1)\cos \beta -\dot{x}\left(1)\sin \beta & =& {x}_{1},\end{array} where α,β∈(0,π)x0,x1∈Rn\alpha ,\beta \in \left(0,\pi ){x}_{0},{x}_{1}\in {{\rm{R}}}^{n} are given and V∈C2(Rn,R)V\in {C}^{2}\left({{\rm{R}}}^{n},{\rm{R}}) is even and is super-quadratic at infinity.…”

A test on the location of tangency portfolio for small sample size and singular covariance matrix by Svitlana Drin, Stepan Mazur, Stanislas Muhinyuza

“…Furthermore, the high-dimensional asymptotic distribution of that test statistic is established when both the rank of the population covariance matrix and the sample size increase to infinity so that $r/n\to c\in (0,1)$. Theoretical findings are completed by comparing the high-dimensional asymptotic test with an exact finite sample test in the numerical study. …”

Distributed SLAM Using Improved Particle Filter for Mobile Robot Localization by Fujun Pei, Mei Wu, Simin Zhang

“…And this paper extends the previously known convergence results for particle filter to prove that improved particle filter converges to the optimal filter in mean square as the number of particles goes to infinity. The experiment results show that the proposed algorithm improved the virtue of the DPF-SLAM system in isolate faults and enabled the system to have a better tolerance and robustness.…”

Global bifurcation of positive solutions for a superlinear $p$-Laplacian system by Lijuan Yang, Ruyun Ma

“…We are concerned with the principal eigenvalue of \begin{equation*} \begin{cases} -\Delta_p u= \lambda\theta_1\varphi_p(v), &x\in \Omega,\\ -\Delta_p v= \lambda\theta_2\varphi_p(u), &x\in \Omega,\\ u=0=v,\ &x\in\partial\Omega \end{cases} \tag{P} \end{equation*} and the global structure of positive solutions for the system \begin{equation*} \begin{cases} -\Delta_p u= \lambda f(v), &x\in \Omega,\\ -\Delta_p v= \lambda g(u), &x\in \Omega,\\ u=0=v,\ &x\in\partial\Omega, \end{cases} \tag{Q} \end{equation*} where $\varphi_p(s)=|s|^{p-2}s$, $\Delta_p s=\text{div}(|\nabla s|^{p-2}\nabla s)$, $\lambda>0$ is a parameter, $\Omega\subset\mathbb{R}^N$, $N> 2$, is a bounded domain with smooth boundary $\partial\Omega$, $f,g:\mathbb{R}\to(0,\infty)$ are continuous functions with $p$-superlinear growth at infinity. We obtain the principal eigenvalue of $(P)$ by using a nonlinear Krein–Rutman theorem and the unbounded branch of positive solutions for $(Q)$ via bifurcation technology.…”

L’infragilimento da idrogeno. Un caso di studio in una barra di comandi di un velivolo dell’aviazione generale. by L. Aiello, M. Colavita, M. Bernabei, V. Di Paolo, M. Amura

“…Tale degradazione si può manifestare sia per l’effetto combinato tra l’ambiente nel quale il velivolo opera e le sollecitazioni cui è sottoposto sia che a causa di anomalie avvenute in fase produttiva che, dopo un periodo di incubazione, manifestano il loro pericoloso effetto: è questo il caso dell’infragilimento da idrogeno che, nel presente articolo che esamina sia i punti critici del processo di produzione che possono indurlo che la morfologia delle superfici di rottura che ad esso si possono ricondurre. Viene infine presentato un caso di studio che ha interessato un velivolo dell’aviazione generale nel quale è stato individuato l’infragilimento da idrogeno di un componente in acciaio AISI 4130 è stata individuata quale causa primaria dell’incidente.…”

La travagliata strada verso l’euro: l’attacco alla lira del settembre 1992 by Michele Alacevich, Francesco Asso

“…Il saggio, inoltre, richiama l’attenzione sull’importanza che gli interessi statunitensi ebbero per la crisi del 1992 e la sua risoluzione. Infine, ricordiamo come la crisi costrinse l’Italia a perseguire una politica virtuosa per aderire al progetto dell’euro e si rivelò, in altre parole, un blessing in disguise. …”

Verso una storia dei fuggitivi in montagna. “Migranti” e genealogie del soccorso alpino e delle lotte by Martina Tazzioli

“…L’articolo continua approfondendo la storia del soccorso alpino al confine franco-italiano, indicando come gli stranieri così come gli “emigranti clandestini” italiani siano stati salvati in questa stessa zona in passato. Infine, si conclude proponendo il concetto di “storia dei fuggitivi” in montagna come quadro teorico che permette una lettura politica dell’attraversamento delle Alpi da parte dei migranti.…”

Optimality criteria for deterministic discrete-time infinite horizon optimization by Irwin E. Schochetman, Robert L. Smith

“…Our main result concerns the case where the discounted per-period costs converge to zero, while the discounted total costs diverge to infinity. Under the assumption that we can reach from any feasible state any feasible sequence of states in bounded time, we show that every efficient solution is also overtaking, thus providing a sufficient condition for overtaking optima to exist.…”
