“…For balance to take place in such a system, the value of Q will change from (1) to (2) by a factor of one-half when the right-sides of both equations are considered. This principle of balance is akin to the principle of circular flow of charges (rising or falling) expatiated upon in the market definition paradigm (Yesufu & Yesufu, 2003). Although a deeper analysis will observe that higher dimensions (three and above), are also dealt with in the market paradigm.…”

“…This concept applies to batteries because when a battery ages, it is less able to hold charge and similar when operating in a less-favourable temperatures. From the MDP , balance points (Voltage in this case) can be either convergent or divergent (Yesufu & Yesufu, 2003).…”

“…This study proposes the use of balance voltage for tracking ageing and temperature variations in these systems (Amir, 2015). The Market Definition paradigm (MDP) offers a variety of tools including equilibrium (balance) approaches to track non-linear systems of which LiBs are (Yesufu & Yesufu, 2003).…”

This article presents a simplified approach for the tracking of ageing and temperature effects in Lithium-ion cells via a balanced cell voltage approach. This balanced cell approach is obtained from the principle of moments of forces based on fundamental physics, in line with the market definition paradigm. Qualitative and quantitative results obtained show that indeed the balance voltage does track ageing and temperature phenomena in these cells. For example, using a chemistry, a safe maximum balance voltage of about 3.23 V while a minimum of about 3.10 V over 2000 cycles was obtained. Similar qualitative and quantitative results were obtained tracking temperature variation effects over a single cycle. This approach will make implementation of cell (and expectedly battery pack) state tracking more cost effective for typical usage scenarios.

“…In the analysis of interacting agents' scenario, such as market-mediated economic interactions or strategic interactions in game theoretic settings with few agents, as explained by Yesufu and Yesufu (2003) and Yesufu and Oladimeji (2008), it has been realized that the market paradigm is a good tool for analyzing time series data, strategic system analysis and network analysis. Hence, the series, t X , is a general form for a stationary series given by…”

An Algorithm for a Sub-Nyquist Rate AM and FM Software-Defined Radio Based on the Market Paradigm

Software-defined radio accomplishes both modulation and demodulation processes using software. While this has a number of advantages, which includes flexibility, interoperability, sustainability, and adaptability, the requirement for sampling the signal for digital processes toward adequate recovery often involves the use of a fast but expensive analogue-todigital converter (ADC). This, in a way translates to higher cost and requirement for bigger storage. This paper presents a method of switched signal recovery at uniform sampling rates that are less than the frequently over-estimated Nyquist rate employed. In particular, an algorithm for achieving this was implemented for an AM wave, under-sampled at varied uniform rates up-to twice the carrier rate, and then demodulated using the Market Paradigm. Furthermore,the slope detectorwas also implemented by including a differentiator after the sampling stage of the algorithm. The simulated results showed that the algorithm was able to recover the message signal at sampling rates far less than twice the carrier rate without the need for any additional hardware. Specifically, the best value of the Spurious Free Dynamic Range (SFDR) obtained for the recovered message signal was 20dB at a sampling rate of less than 20% of the Nyquist rate for the carrier signal.

This study was on the use of the market definition paradigm (MDP) to track ageing and temperature effects in lithium–ion cells. This was with a view to using the technique to obtain a sequence of equilibrium voltages from readily available datasets in order to profile the effects of ageing and temperature on cells and batteries. The method employed involved using the MDP with its capability to obtain a sequence of equilibrium voltages for lithium-ion cells. This approach integrated radio incidence with radio geometry, transmission and emergence in a simplified form of the cell’s equilibrium voltage (and amperage). A standard dataset was obtained from the centre for advanced life cycle engineering repository. The data were processed and analysed using Coulomb counting, charging and discharging energy comparison methods on Python 3.8 programming tool and LibreOffice spreadsheet software. Results obtained show a close tracking of ageing and temperature phenomena in the cells studied. A respective maximum and minimum equilibrium voltages of 3.23 V and 3.10 V over two thousand (2000) cycles were similarly obtained for ageing and temperature investigations. The equilibrium voltage shows a downward trend as the battery ages and is more reliable for studies on these cells than the open circuit voltage traditionally used to track phenomena in such cells. In conclusion, typical lithium-ion cells can be classified at begin-of-life using the equilibrium voltage and useful predictions made with respect to end-of-life. This approach is relatively inexpensive, requiring fewer data points and low-cost hardware and extensible to online applications. Graphical Abstract
