The scattering of 28.5 MeV 3 He particles by 12 C, 20 Ne and 40 A nuclei
1960
Differential cross-sections for the elastic and inelastic scattering of 28.5 MeV 3 He particles by the nuclei 12 C, 20 Ne and 40 A have been measured by means of a photographic technique. The 12 C ( 3 He, α) reaction was also observed. The elastic scattering distributions have been analyzed in terms of an optical model.
Multimode OPOs as Sources for Multipartite Entanglement
2009
We present here multimode OPOs as a source of multimode squeezing and multipartite entanglement of continuous-wave light beams, with applications to the engineering of multimode states of light in the spatial and spectral domains.
An abstract inf-sup problem inspired by limit analysis in perfect plasticity and related applications
2020
This work is concerned with an abstract inf-sup problem generated by a bilinear Lagrangian and convex constraints. We study the conditions that guarantee no gap between the inf-sup and related sup-inf problems. The key assumption introduced in the paper generalizes the well-known Babuska-Brezzi condition. It is based on an inf-sup condition defined for convex cones in function spaces. We also apply a regularization method convenient for solving the inf-sup problem and derive a computable majorant of the critical (inf-sup) value, which can be used in a posteriori error analysis of numerical results. Results obtained for the abstract problem are applied to continuum mechanics. In particular, …
Determination of charge carrier mobility of hole transporting polytriarylamine-based diodes
2010
Hole transport properties of three different side chain poly(triarylamines) have been determined by means of the analysis of steady-state current-voltage characteristics using co-planar diode structures. The interpretation is based on space-charge limited models with field-dependent mobility. Mobilities between ~ 10- 8 and 10- 6 cm2 V- 1 s- 1 are obtained. The highest mobility is achieved for poly(tetraphenylbenzidine) devices and the lowest for poly(triphenylamine) devices. Electron-rich methoxy substituents increase the mobility of poly(triphenylamine)s. A comparison of the mobility values with those obtained using organic field-effect transistors is also given. © 2009 Elsevier B.V. All r…
DC series arc faults in PV systems. Detection methods and experimental characterization
2020
This work is focused on the arc faults phenomenon in DC photovoltaic (PV) systems. The paper gives an overview of arc detection methods proposed in literature and presents a preliminary experimental characterization of the arcing current, focusing the attention on series arcs, whose detection is particularly challenging. Experimental tests are carried out, both in laboratory and on field, in order to investigate some relevant characteristics in the arcing current, which can be feasible for the arc detection purpose. Both arcing and non-arcing current signals are acquired and compared in both time and frequency domain. On-field measurements are carried out on a real photovoltaic system, in a…
Pakomāta spraudņa izveide WooCommerce interneta veikaliem
2016
Pakomātu spraudnis WooCommerce internetveikaliem ir uzstādāms spraudnis, kas “Wordpress” sistēmām, uz kurām ir uzstādīts e-komercijas rīks “WooCommerce”, pievieno piegādes veidus, kas ļauj klientiem izvēlēties iespēju saņemt savu preci pakomātu stacijās. Spraudnis ļauj internetveikala pārvaldniekam ērti un ātri pievienot, dzēst , kārtot adreses katram piegādes veidam. Adrešu datus var gan vadīt sistēmā manuāli, gan importēt no oficiālajām Latvijā reģistrētajiem pakomātu automātu uzņēmumiem, kas būtiski atvieglo darbu ar piegādes veidu uzstādīšanu. Sistēma sastāv no 5 moduļiem – •Instalācijas/ deaktivizācijas modulis •Piegādes veidu modulis •Klienta modulis •Importu modulis •Adrešu modulis

Sublimable chloroquinolinate lanthanoid single-ion magnets deposited on ferromagnetic electrodes
2018
A new family of chloroquinolinate lanthanoid complexes of the formula A+[Ln(5,7Cl2q)4]−, with Ln = Y3+, Tb3+ and Dy3+ and A+ = Na+, NEt4+ and K0.5(NEt4)0.5+, is studied, both in bulk and as thin films. Several members of the family are found to present single-molecule magnetic behavior in bulk. Interestingly, the sodium salts can be sublimed under high vacuum conditions retaining their molecular structures and magnetic properties. These thermally stable compounds have been deposited on different substrates (Al2O3, Au and NiFe). The magnetic properties of these molecular films show the appearance of cusps in the zero-field cooled curves when they are deposited on permalloy (NiFe). This indic…
Influence of Ad Congruence and Social Cues on the Probability of Choosing a Restaurant
2020
Abstract. Information processing of digital content includes conscious and un-conscious processes, memory, attitudes, and emotions and moods. Build up into the Heuristic‐Systematic Model, that states that persuasion can occur through a systematic or heuristic way, this research explores the effect of social media (SM) ratings and the ad content embedded in the SM website. Online ratings (part of the user-generated content (UGC) in SM platforms) are often heuristics cues. Subtle forms of congruence, such as the matching category between a restaurant advertiser and the third-party ad, as well as UGC, could have an impact on con-sumers’ attitudes towards the former. However, research on …
