Using Machine Learning to Detect Fraudulent SMSs in Chichewa
Amelia Taylor, Amoss Robert
SMS enabled fraud is of great concern globally. Building classifiers based on machine learning for SMS fraud requires the use of suitable datasets for model training and validation…
Legitimization of Data Quality Practices in Health Management Information Systems Using DHIS2. Case of Malawi
Martin Bright Msendma, Wallace Chigona, Benjamin Kumwenda +2
Medical doctors consider data quality management a secondary priority when delivering health care. Medical practitioners find data quality management practices intrusive to their o…
Adaptive Geostatistical Design and Analysis for Sequential Prevalence Surveys
Michael G. Chipeta, Dianne J. Terlouw, Kamija Phiri +1
Non-adaptive geostatistical designs (NAGD) offer standard ways of collecting and analysing geostatistical data in which sampling locations are fixed in advance of any data collecti…
Increase of cationic concentration due to bending of overcharged DNA in strong Coulomb coupling regime
Arup K Mukherjee
This study reveals that, in strong coulomb coupling regime, bending a straight and fully overcharged DNA (up to its maximal acceptance by multivalent counterions) to a circle relea…
Variable-length Hill Cipher with MDS Key Matrix
Kondwani Magamba, Solomon Kadaleka, Ansley Kasambara
The Hill Cipher is a classical symmetric cipher which breaks plaintext into blocks of size m and then multiplies each block by an m by m key matrix to yield ciphertext. However, it…
Electrostatic contribution to DNA condensation - application of 'energy minimization' in a simple model in strong Coulomb coupling regime
Arup K. Mukherjee
Bending of DNA from a straight rod to a circular form in presence of any of the mono-, di-, tri- or tetravalent counterions has been simulated in strong Coulomb coupling environmen…
