In this paper a new 5-level single phase symmetrical cascade multi-level inverter is proposed. The proposed topology contains combination of unidirectional and bidirectional power switches based on output voltage level number. The number of power switches and withstanding voltage of powers witches were reduced related to the other topologies. This configuration can be extended to the n-level in...

Robustness is an important and challenging issue in Internet of Things (IoT), which contains multiple types of heterogeneous networks. Improving the robustness of topological structure, i.e., withstanding a certain amount of node failures, is of great significance especially for the energy-limited lightweight networks. Meanwhile, a high-performance topology is also necessary. The small world mo...

Abstract Nowadays, continuous development of soft-electronics and wearable devices opens to the needs stretchable flexible materials able interface with human body. In this scenario, biopolymers are particularly intriguing given their biocompatibility biodegradability. For application in specific field material requires several properties such as biological mechanical performance thermal stabil...

High-voltage electrical cables are prone to saline corrosion, mostly in coastal environments. Steel wires a crucial element withstanding the mechanical solicitations of commonly used aluminum conductor steel reinforced (ACSR) cables. An experimental accelerated corrosion test was made, using salt spray tests on greased and ungreased ACSR individual galvanized wires. The mechanism occurring spec...

Effect of thermal radiation on reliability is investigated for ZnO-based multilayer ceramic varistors (MLCVs). Withstanding capabilities against load dump surge (LDS) are compared between MLCVs with connecting structure various-sized chips (co-MLCVs) and large size ones (5.7 × 5.0 3.0 mm). The LDS stability improved surface area co-MLCVs. In particular, when connected under 3.2 2.5 1.6 mm in si...

Nomex honeycomb is used as the predominate core material in aerospace standard sandwich structure. To provide aerospace standard composite face sheets it is necessary to cure the sandwich structure in an autoclave at elevated pressure. The honeycomb material is capable of withstanding the forces experienced through its thickness, but the lateral forces applied by the elevated pressure cause a c...
