The paper addresses a development and application of EKV MOS transistor compact model with focus on the ultra low-voltage / ultra low-power analog integrated circuit (IC) design employing bulk-driven (BD) technique. The presented contribution can be viewed as an extension of standard EKV model application and as a contribution to ultra low-voltage IC design techniques. The paper compares the measured and extracted small-signal parameters of standalone transistor samples fabricated in 130 nm CMOS technology and the simulation results obtained using the proposed bulk-driven EKV v2.63 model and foundry-provided BSIM model v3.3. The transistor samples were analyzed with power supply of VDD = 0.4 V The paper also discusses the implementation of 3D graphs as a result of introducing another degree of freedom into the essential MOS transistor characteristics, while maintaining the ease of using the design hand-calculation with the original gm/ID approach.

Many rural and low-income areas around the globe have poor quality (or no) internet service with limited telephone coverage due to a lack of infrastructure, insufficient power supply, and a limited core telecommunications network. Because of limited mobile device propagation capabilities, sparse population density and poor purchasing power, it is not economically feasible for mobile operators to deploy traditional communication networks in these regions. Researchers recently discovered that a portion of the underutilized TV spectrum known as TV white space (TVWS) could be suitable for those areas in terms of bandwidth, improved reception features, good penetration of buildings, and broad reach. This paper presents a comprehensive evaluation of available TVWS channels in Ethiopia using a Geolocation Database front-end (GLSD) aided by the CSIR Calculation Engine hosted by the CSIR Meraka Institute. GLSD and the CSIR calculation engine together are able to quantify the amount of TVWSs through dynamically allocating the TVWS network radio services according to the geographic position of WSDs. The GLSD was developed using the ITU-R P.1546-5 propagation model. Using the GLSD and the CSIR calculation engine, the quantification of TVWS free channels are calculated. The results show that among the 58 VHF and UHF TV channels, 52 of the channels are free (underutilized) in Ethiopia. These free channels can be employed to provide wireless broadband solutions for connecting the rural areas as well as offloading the urban traffic.

An analysis on the viability of implementing non-flow based capacitive biosensing for bulk counting of whole cancer cells is presented. A mathematical model is implemented based on established research to test the validity of the hypothesis that cells are considered to act like parallel electric connections. A finite element analysis model is also presented to investigate the effect of electrode geometry and cell position on the measured capacitance. The electrical interaction between cells is found not to be strictly parallel and in fact dependent on a host of uncontrollable parameters. Bulk sensing of multiple cells is found to be impractical for a single electrode setup due to the unpredictability of cell location and cell interactions. An array-based implementation is proposed, which allows for the use of current models and data of single-cell analyses to be used.

Electricity network modelling and grid simulations form a key enabling element for the integration of newer and cleaner technologies such as renewable energy generation and electric vehicles into the existing grid and energy system infrastructure. This paper reviews the models of the African electricity systems and highlights the gaps in the open model landscape. Using PyPSA (an open Power System Analysis package), the paper outlines the pathway to a fully open model and data to increase the transparency in the African electricity system planning. Optimisation and modelling can reveal viable pathways to a sustainable energy system, aiding strategic planning for upgrades and policy-making for accelerated integration of renewable energy generation and smart grid technologies such as battery storage in Africa.

The dynamic nature of threats associated with electronic warfare (EW) requires state-of-the-art algorithms to cater for these threats. In recent times, electronic intelligence (ELINT) is being used to solve this challenge in various subfields. This paper presents an ELINT system which is used to determine the identity of captured radar signals through the use of instantaneous power (IP). The IP was obtained via three approaches which are used to estimate the basic time-parameters (pulse width (PW) and pulse repetition period (PRP)) of the simple pulsed radar signal. The simple pulsed radar signal is characterize by constant time parameters and a sinusoidal modulation of constant frequency. The three approaches employed involved two approximate methods such as time-marginal and maxima of a modified version of the Wigner-Ville distribution (WVD) and while the last is the conventional way of getting instantaneous power using the conjugate version of the signal. The method of analysis is validated using an additive white Gaussian noise (AWGN) at various signal-to-noise ratios (SNR) and selected threshold values of 25%, 37.5 %, and 50%. The results obtained show that the IP obtained directly is the most versatile method as accurate PW and PRP estimation were obtained at SNR of -15 dB at different threshold values while approximate method via the maxima of WVDis the best method with a lower minimum SNR of -18 dB at threshold value of 37.5%. The latter case therefore allows for usage of WVDfor other parameters estimation in the field without developing another separate signal processing method for time parameter estimation.

Many countries in the world, in particular the least developed ones, face the challenge of unhealthy drinking water. In this paper, the design and implementation of a trackable and notification-enabled remote water quality monitoring system prototype is proposed to mitigate this problem. The system is aimed at remotely monitoring the quality of water in fixed or erected and motorized or mobile storage water tanks. The system can be adopted for use by countries to enhance their rural villages’ water supply schemes and to help remote villages have access to clean and healthy drinking water. Besides quality monitoring, the system also features location tracking in the case of motorized tanks, which get transported to different destinations as part of the rural water supply schemes.

This work reports the investigation results on how dielectric properties of soil change with fertilizer concentration for catena in Mwanza of Tanzania at 945 MHz frequency band using reflection measurement. Composite soil samples were collected from three catenas: upper, middle, and lower catena sites in Misungwi district located in Mwanza, Tanzania. Two chemical fertilizers UREA and CAN were used since they are widely used in these areas. With the low-cost equipment, reliable results are obtained that show relationship of soil fertility and dielectric properties. The results provide essential information for preparing on-farm measurement to get soil fertility contour that supports land management.
