Depression disorder is common in primary care, but its diagnosis is complex and controversial due to the conflicting, overlapping and confusing nature of the multitude of symptoms, hence the need to retain cases in a case base and reuse effective previous solutions for current cases. This paper proposes a neuro-fuzzy-Case Base Reasoning (CBR) driven decision support system that utilizes solutions to previous cases in assisting physicians in the diagnosis of depression disorder. The system represents depression disorder with 25 symptoms grouped into five categories. Fuzzy logic provided a means for handling imprecise symptoms. Local similarity between the input cases and retrieved cases was achieved using the absolute deviation as the distance metric, while adaptive neuro-fuzzy inference system handled fuzzy rules whose antecedents are the mapped local similarities of each category of symptoms for global similarity measurement, upon which the retrieved cases are ranked. The 5 best matched cases are subjected to the emotional filter of the system for diagnostic decision making. This approach derives strengths from the hybridization since the tools are complementary to one another.

The study aimed to assess whether the students from mathematical science-based undergraduate degree programmes in Kaduna State University perform academically better when either the Computer-Based Test (CBT) or the Paper-Pencil Test (PPT) is used to write the Unified Tertiary Matriculation Examination (UTME), which is conducted annually by the Joint Admissions Matriculation Board (JAMB). The study adopted a quantitative approach to research. A purposive sample of one thousand and twenty-three (1023) first-year students constituted the population for the study. This population

This paper is concerned with choosing a subset of FORTRAN which will make it possible to write portable programs on medium‐sized microcomputers. To achieve this, some restrictions are placed on ANSI 1966 Standard FORTRAN after studying and analysing a collection of FORTRAN manuals for medium‐sized microcomputers. Some assumptions are made concerning machine dependent constants after a careful observation. By combining these restrictions with those made in compatible Fortran1 and making use of the assumptions, portable programs can be written.
