A review of the two integrator loop oscillator circuits providing two quadrature sinusoidal output voltages is given. All the circuits considered employ the minimum number of capacitors namely two except one circuit which uses three capacitors. The circuits considered are classified to four different classes. The first class includes floating capacitors and floating resistors and the active bui...

Monte Carlo modelling has been performed in support of efforts to establish emergency dosimetry services based on optically or thermally stimulated luminescence (OSL/TL) of the Al(2)O(3) substrate present on the resistors found in mobile phones, which can act as fortuitous retrospective dosemeters for photon exposures. Specifically, a range of exposure conditions has been modelled to assess the...

2023 will be the second year of my service as President IEEE Nanotechnology Council (NTC). As outlined in 2022 Message, mantra presidency is rooted pursuing following initiatives.

Pre-ignition, involving complex interactions of physical and chemical processes, occurs not only in actual combustion engines but also fundamental research equipment such as rapid compression machines shock tubes. Thus, identifying the conditions prone to pre-ignition is critical for interpretation ignition data fuel design. Shock tube experiments with dimethyl ether (DME) were carried out this...

A power divider with ultra-wideband (UWB) performance has been designed. The quarter-wave transformer in the conventional Wilkinson power divider is replaced by an exponentially tapered microstrip line. Since the tapered line provides a consistent impedance transformation across all frequencies, very low amplitude ripple of 0.2 dB peak-to-peak in the transmission coefficient and superior input ...

Surface mount chip resistors are amongst the simplest and most inexpensive of all components used in electronic circuits and systems. Typically, resistor failure modes include open circuits, resistive shorts or variations in resistance indicating parametric drift or intermittent failure, which in some applications result in overall system failure. Corrosion is currently believed to be the numbe...

The object of this paper is to show that a certain system of nonlinear differential equations has one and only one periodic solution. These equations are of interest in that they describe the vibrations of a common type of electric network; therefore, the physical origin of the equations will be discussed first. A linear network is a collection of linear inductors, linear resistors, and linear ...

The NTC has contracted Chula UniSearch, a consulting arm of Chulalongkorn University (CU), led by Dr. Supavadee Aramvith and Dr. Chaodit Aswakul, to operate the project which is participated by CAT Telecom, Samart Telecom, AIS, NEC, Rohde&Schwarz, FORTH and ADC Communications. NGN technologies such as 3G, Wi-Max, VoIP, SIP server/Soft switch, VoD and FTTH are evaluated in the project along with...

Networks of resistors have been identified as interesting devices for analog computation. Since the analytical model of a network of constant resistors is a set of linear equations, such a circuit can be used to solve a large number of linear equations concurrently. Whenever such a resistive embodiment of a computational problem can be found, the resulting circuit is usually very simple, fast a...
