Comparing the “Rim” Versus the “Filled” Rectangular Array Grids—Their Direction-Finding Cramér-Rao Bounds
(IEEE, 2018)A rectangular array of sensors is often used in direction finding, due to the geometric regularity in its spatial rectangular grid. The sensor positions may be confined to the rectangle's perimeter (as in a “rim” array), ... -
Comparison of a gas fired hot-air dryer with an electrically heated hot-air dryer in terms of drying process, energy consumption and quality of dried onion slices
(Academic Journals, 2012-08-14)Onion slices were dried in either a gas-fired hot air dryer or an electrically heated hot air dryer at air temperatures of 50, 60 or 70°C, and at air flow velocities of 0.5, 1.0 or 2.0 m/s. Records of the drying rates and ... -
Comparison of Double-Incision Laparoscopic Cholecystectomy and Needlescopic Cholecystectomy
(Scientific Research, 2013-12)Purpose: Recently, reduced port surgery is becoming popular for laparoscopic surgery. “Reduced” means reducing the size or number of ports, but it is controversial as to which procedure is better. We evaluated double-incision ... -
Comparison of Indoor Localization Systems Based on Wireless Communications
(Scientific Research Publishing, 2011-10)Localization using a Wireless Sensor Network (WSN) has become a field of interest for researchers in the past years. This information is expected to aid in routing, systems maintenance and health monitoring. For example, ... -
A Comparison of the physico-chemical and bacteriological quality of greywater from water deficient households in Homabay Town and Githurai Estates in Kenya.
(Academic Journals, 2012)Greywater, the untreated household wastewater that has not been contaminated by toilet waste, has been touted as a reliable all year-round source of water, especially in water scarce areas. Although it is commonly reused ... -
Comparison of the phytochemicals and antimicrobial activity of leaf extracts of Calotropis procera, Momordica charantia and Allium ascalonicum
(African Journal of Biological Sciences, 2020-04-06)The emergence of new infectious diseases, resurgence of several infections that appeared to have been controlled and the increase in bacterial resistance has led to the need for studies directed towards the development of ... -
Competence of Tropical Maize Lines to Agrobacterium-Mediated Transformation and the Expression of Maize Poly (ADP-Ribose) Polymerase (PARP2) Gene under Drought Stress.
(Kenyatta University, 2017)Drought stress affects many maize growing regions in sub-Saharan Africa. As population increases, the gap between maize supply and demand increases. There is, therefore, need to develop maize lines that are tolerant to ... -
