Abstract A well-known conjecture of Gilbreath, and independently Proth from the 1800s, states that if $$a_{0,n} = p_n$$ a 0 , n = p denotes n th prime number $$a_{i,n} |a_{i-1,n}-...

The capacitor has become the dominant passive component for analog circuits designed in standard CMOS processes. Thus, capacitor matching is a primary factor in determining the precision of many analog circuit techniques. In this paper, we present experimental measurements of the mismatch between square capacitors ranging in size from 6 pm x 6 pm to 20 pm x 20 pm fabricated in a standard 2 pm d...

DESIGN AND IMPLEMENTATION OF A FOUR TERMINAL FLOATING AMPLIFIER AND ITS APPLICATION IN ANALOG ELECTRONICS By José A. García Rivera The field of analog electronics has developed and matured for the past two decades. Within this field, design of analog amplifiers has received attention due to changes in technology. Amplifier circuits, considered analog devices, are found anywhere in many house el...

This work describes the methods and techniques used for the development of a multipurpose station to perform experiments in isolated places. Its application in a system to characterize solar cells is presented, where capturing of electrical and environmental data is required. Obtained results allow to compare the performance of new and conventional photovoltaic devices, and also to characterize...

In order to get an efficient specification and simulation of a heterogeneous system, the choice of an appropriate model of computation (MoC) for each system part is essential. The choice depends on the design domain (e.g., analogue or digital), and the suitable abstraction level used to specify and analyse the aspects considered to be important in each system part. In practice, MoC choice is im...

Wine production is climate dependent and highly sensitive to weather variability, which makes the sector a good indicator of ongoing and future climate change impacts. Under high-end climate change (HECC), temperatures in Scotland are projected to increase significantly by the end of the twenty-first century. This raises the possibility of future temperatures becoming sufficiently high to suppo...
