2. DESIGN OF ELECTRONIC CONTROL GOVERNOR FOR A SINGLE CYLINDER GASOLINE ENGINE BASED ON AN INTELLIGENT SENSING ALGORITHM
ABSTRACT At present, most large machinery and vehicle engines are electronically controlled but their electronic control systems are too expensive to be popularised and applied in small gasoline engines with relatively low prices. Therefore, small gasoline engines still use mechanical speed regulators. Mechanical speed regulators not only have the defects of

6. Development and Characterization of PbI2 Nanoparticles for all Solid-State Flexible Supercapacitor Purposes
The development and utilization of new energy sources has been extensively studied in the world. Here, we report the development of flexible self-supported metal-free electrodes based on non-oxidized graphene multilayer (MLG) paper containing the lead iodide nanoparticles (PbI2-NPs). The PbI2-NPs was obtained and characterized by X-ray diffraction (XDR) and

7. O CONCEITO DE VALÊNCIA EM LIVROS DIDÁTICOS DE QUÍMICA GERAL ENTRE AS DÉCADAS DE 1890 E 1940
This paper aims to investigate the presentation of the concept of valence in college-level, general chemistry textbooks published in the USA between the 1890s and the 1940s. The delimited period covers the emergence of theories about atomic structure, electronic distribution and chemical bonding. Transition from the classical concept of valence (as the combi

8. Investigation on Solar PV generation and design of switched reluctance motor for Smart Agriculture actuation system
ABSTRACT This paper presents standalone solar photovoltaic (PV) powered fed actuation system employing a switched reluctance motor (SRM) particularly used in remote and rural areas. The converter efficiency is achieved by changing ON and OFF state of solar PV drive. An electronic commutation drives SRM drive with achieved by position hall sensor and encoder.

9. Public Policy Instruments and Their Impact: From Analogue to Electronic Government in the Bus Services of São Paulo
This article deals with the relations between public policy instruments and production practices of objects related to government action. It demonstrates that the materiality of the instruments built to make a public policy object legible to its operators has independent effects on the relations among private operators, bureaucrats, and the public sector.

10. Low cost system to measure active power in electrosurgical units
Abstract Introduction: The real-time measurement of active power delivered to patients during the electrosurgical act is still an engineering challenge. Besides, there is no electrosurgical unit on the market capable of doing it according to the normative requirement. Methods This work presents the design of an electronic structure capable to probe the ele

11. Influence of Si Coating on Interfacial Microstructure of Laser Joining of Titanium and Aluminium Alloys
A common phenomenon in the dissimilar joints is the presence of brittle compounds in the joining interface region. The brittle phases can decrease by introduction of interlayers in the joining interface, such as silicon, that inhibits the formation of Al3Ti and AlTi3 phases in joining process between titanium and aluminium alloys. In the present work, the jo
