NanoScale TiO2 based Memory Storage Circuit Element:- MemristorAM Publications
This document discusses the memristor, a fourth fundamental circuit element predicted by Leon Chua in 1971. In 2008, HP Laboratories created the first physical model of a memristor using a thin film of titanium dioxide sandwiched between platinum electrodes. This memristor exhibits variable resistance depending on the charge that has passed through it, fulfilling Chua's prediction. While this initial design had limitations like low speed and heat dissipation, memristors show potential for applications like non-volatile memory, neuromorphic computing, and new circuit designs. Further research is still needed to improve memristor models and address challenges for practical applications.

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

1. (a) Two resistances when they are in series has an equivalent resistance of 9 ohms
and when connected in parallel has an equivalent resistance of 2 ohms. Find
the resistances and the ratio of the voltage and current sharing between these
elements if supply voltage is 50V.
(b) Find the equivalent resistance between the terminals AB in the network as
shown in gure 5b, if each has a resistance of R ohms and hence nd the total
current, current through each of the element if the total voltage is 45V. [8+8]

2. The number of turns in a coil is 250. When a current of 2A ows in the coil, the
ux in the coil is 0.3mwb. When the current is reduced to zero in 2ms, the voltage
induced in a coil lying in the vicinity of the coil is 63.75V. If the co-e cient of
coupling between the coils is 0.75, nd.
(a) The self inductance of two coils.
(b) Mutual inductance.
(c) Number of turns in the second coil.
Derive the formulae used. [16]
3. Why the rms values of an alternating quantity is more important than its average
value. Find the rms value of the resultant current in a conductor which carries
simultaneously sinusoidal alternating current with a maximum value of 15A and
direct current of 15A, by deriving necessary expressions. [16]
4. A symmetrical 3-phase, 3-wire, 440V supply is connected to a star connected load.
The impedances in each branch are : Z1=(2+j3) , Z2=(1-j2) , Z3=(3+j4) . Find
its equivalent delta connected load. Hence nd the phase and line currents and the
total power consumed in the circuits. [16]
