Diversity of esterase and lipase producing haloalkaliphilic bacteria from Lake Magadi in Kenya
(2019-09)Lipids are hydrocarbons comprised of long‐chain fatty acids and are found in all living things. In the environment, microorganisms degrade them to obtain energy using esterases and lipases. These enzymes are nowadays ... -
A Classification Model for Water Quality analysis Using Decision Tree
(2019-06)A classification algorithm is used to assign predefined classes to test instances for evaluation) or future instances to an application). This study presents a Classification model using decision tree for the purpose of ... -
Cramer-Rao Bound of Direction Finding Using a Uniform Hexagonal Array
(2019-06)Direction-of-arrival (DOA) estimation is a key area of sensor array processing which is encountered in many important engineering applications. Although various studies have focused on the uniform hexagonal array for ... -
A uniform circular array of isotropic sensors that stochastically dislocate in three dimensions—The hybrid Cramér-Rao bound of direction-of-arrival estimation
(2019-07)An array’s constituent sensors could be spatially dislocated from their nominal positions. This paper investigates how such sensor dislocation would degrade a uniform circular array (UCA) of isotropic sensors (like ... -

(2019-09)Source direction-of-arrival estimation problem has received much attention in recent years following its significant role in array-signal processing and wide range of applications such as radar, wireless communication, ... -
An Assessment of Suitable and Affordable Smart armband for preeclampsia Management in Antenatal Care
(2019-06)Blood pressure is one of the measurements that is taken during antenatal care visits. Though motherhood is a fulfilling experience in the society, it is connected to ill-health and even death in some women leading to ... -
A 24-hour ambulatory blood pressure monitoring system for preeclampsia management in antenatal care
(Elsevier, 2019-06)The burden of preeclampsia has been a major concern worldwide both in developed and developing countries, making its prevention and management a major concern. Although motherhood is a fulfilling experience in society, ... -
Copper extraction by wet chemical method
(Elsevier, 2018-07)In many countries large deposits of copper with no locally established copper based industries occur because known methods for extraction are prohibitively expensive and unaffordable. This study reports on an affordable and ... -
Properties of activated blended cement containing high content of calcined clay
(Elsevier, 2018-08)This paper presents findings of an experimental investigation on sodium sulphate (Na2SO4) activated calcined clay e Portland cement blends in sulphuric acid media. Calcined clays were blended with Ordinary Portland Cement ... -
Review of Carbonation Resistance in Hydrated Cement Based Materials
(Hindawi, 2019)Blended cements are preferred to Ordinary Portland Cement (OPC) in construction industry due to costs and technological and environmental benefits associated with them. Prevalence of significant quantities of carbon dioxide ... -
