1. 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.

2. Construction and measurement of an electromagnetic noise generator based on an automotive coil
This article covers the design of an electromagnetic noise generator which uses an automotive coil as the main component. A short theoretical analysis covers the generation of high voltage pulsed current from the available DC source originated from the battery. An electronic dimmer, a circuit used to control the brightness of a light, by controlling the effe

3. Análise do comportamento eletroaeroelástico de uma seção típica para geração piezelétrica de energia / Electroaeroelastic behavior analysis of a typical section for piezoelectric energy harvesting
Converting aeroelastic vibrations into electricity for low power generation has received growing attention over the past few years. In addition to potential applications for aerospace structures, the goal is to develop alternative and scalable configurations for wind energy harvesting to use in wireless electronic systems. The use of a typical airfoil sectio

5. ASSOCIAÇÃO DO CONTEXTO DE INTERESS DO USUÁRIO ÀS ATIVIDADES CLÍNICAS NA ARQUITETURA CLINICSPACE / Association of the Context of Users Interesting to Clinical Activity in Architecture ClinicSpace
Currently, we seek to make the systems more oriented to end-user, reducing the distance between how the user carries out its activities and modeling these in Information Systems in Health, the doctor providing adaptive and personalized forms of use, configuration and control system, based on historical usage, or a profile. To meet these requirements, the pro

6. Desajuste marginal e influencia na pre-carga de parafusos e nas tensões induzidas as fixações de pilares metaloplasticos sobre-fundidos / Marginal misfit and influence in the pre-load and the stress-induced setting of the metaloplastic abutments
Castable UCLA abutments are of wide applicability in dental implants, because they allow the manipulation in the laboratory at low cost and individualization of abutments for each patient. However, they show the worse results of marginal adaptation then the fabricated, although these aggregate costs significantly higher. UCLA premachined abutments for castin

8. Estudo experimental da influência de um ressonador de volume variável na massa de ar admitida por um motor de combustão interna
The dynamic of intake manifold admission on internal combustion engines involves parameters such as length, diameter, camshaft rotation and other geometries and accessories. The alternative movements of the admission valves and piston produce the phenomena of generation of pressure waves that spread through the conduit. Such waves, if well used, can increase
