Similar to other poor countries across Africa, Malawi struggles with solid waste management (SWM). Especially considering the high proportion of organic waste, composting is a promising opportunity tackle problem. However, has had low uptake due competing fertilizer subsidies, perceived labour required, and lack training equipment. Considering these issues, this paper presents an analysis polit...

We report experimental studies of bright-state polaritons of four-wave mixing (FWM) and six-wave mixing (SWM) signals through cascade nonlinear optical parametric amplification processes in an atom-cavity composite system for the first time. Also, the coexisting cavity transmission modes of parametrically amplified FWM and SWM signals are observed. Finally, electromagnetically induced absorptio...

Sensitivity analysis on Sea Surface Temperature: SST estimation with Thermal Infrared Radiometer: TIR data through simulations is conducted. Also Conjugate Gradient Method: CGM based SST estimation method is proposed. SST estimation error of the proposed CGM based method is compared to the conventional Split Window Method: SWM with a variety of conditions including atmospheric models. The resul...

Highly efficient four-wave mixing (FWM) and six-wave mixing (SWM) processes can coexist in a four-level Y-type atomic system due to atomic coherence. The simultaneously opened dual electromagnetically induced transparency windows in this four-level atomic system allow observation of these two nonlinear optical processes at the same time, which enables detailed studies of the interplay between t...

Behavioural ecologists increasingly recognise spatial memory as one the most influential cognitive traits involved in evolutionary processes. In particular, spatial working memory (SWM), i.e. the ability of animals to store temporarily useful information for current foraging tasks, determines the foraging efficiency of individuals. As a consequence, SWM also has the potential to influence compe...

The solid waste management (SWM) sector is responsible for the emission of about 5% all global greenhouse gas (GHG) emissions. In developing countries where less organised, carbon footprint much higher, so also potential reducing these This study assessed GHGs from SWM in northeastern Nigeria. Based on literature study, it was found that open dumping dumpsites and unsanitary landfills a disposa...

In this paper, we experiment with a small working model (SWM), where we can inject faults and learn the intelligence about the system, then scale up this fault models to monitor the condition of an actual/complex system, without injecting faults in the actual system. We refer to this approach as scalable fault models. We check the effectiveness of our approach using 3 kVA and 5 kVA synchronous ...

We demonstrate efficient energy exchange during propagation between four-wave-mixing FWM and sixwave-mixing SWM signals generated in a four-level inverted-Y atomic system, which fall in the electromagnetically induced transparency window. After an initial growth distance for both FWM and SWM fields in the atomic medium, these two nonlinear optical processes compete and exchange energy between t...

We study the convergence rate of MCMC on the statistically unidentifiable nonlinear model involving the Michaelis-Menten kinetic equation. We have shown that, under certain conditions, the convergence diagnosis of Raftery and Lewis (1992) is consistent with the convergence rate argued by Brooks and Roberts (1999). Therefore, different MCMC schemes developed in linear models are further extended...

Abstract Applied as a bedside test of gross dorsal column function, the testing of light touch (LT) sensation is of high clinical value in the diagnosis of human spinal cord injury (SCI). However, the assessment of overall dorsal column deficit by testing only LT may be limited, because the dorsal column pathway conveys several large diameter afferent modalities (e.g., sensation of touch, two-p...
