A proposed fish counting algorithm using digital image processing technique

Abstract: Fish product contributes a significant amount of protein demand of human nutrition and made up of about 16% of human diet all around the world. However, Fish production is one of the factors that have been a bottleneck for development of fish farming for most developing countries such as Nigeria. One of the major and time consuming task in production is providing an accurate estimate of the fingerlings to farmers. The methods of counting fingerlings in most developing countries is done manually. These manual methods are inevitably influence by inaccuracies and exposer of the fingerlings to unnecessary stress that could lead to death. This paper proposed a fingerling counting algorithm using digital image technique. To achieved this aim, a robust segmentation algorithm, feature extraction algorithm and machine learning algorithm for fingerlings classification and counting are hereby formulated. At the end of this research, the proposed algorithm is expected to count different sizes of fingerlings with high accuracy.

Design of 5g Mobile Millimeter Wave Antenna

Abstract: This paper present the design and simulation of a single band microstrip patch antenna for 5G wireless application operating at 60GHz. The design is carried on Roger RT5880 with 2.2 dielectric, 0.0009 loss tangent and 0.003 mm thickness using inset feeding. The overall dimension of the patch antenna is 2.9 A— 3.5 mm 2 , two rectangular U-slot in conjunction with H-slot were loaded into the radiator to enhance the antenna bandwidth. The antenna is design and simulated and the analysis were carried out on CST studio. The antenna achieve a maximum reflection coefficient of about -41.648731 dB at 60 GHz with a very wide bandwidth of about 30 GHz and 8.82 dB realized gain.

Direct and Indirect Transmission Dynamics of Typhoid Fever Model by Differential Transform Method

Abstract: The aim of this paper is to apply the Differential Transformation Method (DTM) to solve typhoid fever model for a given constant population. This mathematical model is described by nonlinear first order ordinary differential equations. First, we find the solution of this model by using the differential transformation method (DTM). In order to show the efficiency of the method we compare the solutions obtained by DTM and RK4. We illustrated the profiles of the solutions, from which we speculate that the DTM and RK4 solutions agreed well .

Technical drawing/ graphic skills acquisition for teaching and learning and challenges in technology education

Abstract: Due to the current technological development and changing demands in the society and labour market it become necessary for teaching and learning to devices the means for overcoming the challenges in technology education and in particular technical drawing/graphic these could only be successful through sound pedagogy and information computer technology (ICT), application of these will improve, enrich and sustain employability. There is rapid changes in the fields of computer aided design (CAD), difficulties in visualizing multi-view drawing and use of ICT in the teaching methodology, becomes an open challenges facing Technical Graphic/Drawing skills acquisition for teaching and learning. The study reviews the challenges facing technical graphic/ drawing skills acquisition, the use of ICT in the teaching methodology and the essentials issues related to the enhancement of teaching and learning. The reviews revealed that learners find it difficult in the Visualizing a Multi-view Drawing and used of CAD. Various researches discover that, the used of ICT such as Computer Animated Module for Engineering Drawing (CAMED) and multimedia computer-based instruction enhances Technical Graphic/ Drawing skills acquisition for teaching and learning. The study clearly shows that there are difficulties faced by both learner and teacher of technical drawing and especially in the teaching and learning situation. Also, shows the significance of the use of CAD and ICT to enhance teaching methodology and to promote Continuing Professional Development and Learning. In conclusion recommendations were suggested based on the document analysis and findings.

Analysis of technical inefficiency in food crop production systems among small-scale farmers in some selected local government areas of adamawa state, nigeria.

Abstract: Efficient allocation of resources has been a problem in small holder farm economy in Nigeria. The study examined the technical inefficiency in food crop production systems among small-scale farmers in selected Local Government Areas of Adamawa State, Nigeria. Specifically, the socio - economic characteristics of food crop farmers in the study area were described , the va rious cropping patterns of the farmers were identified and technical inefficiency of the farmers analysed. Data were collected from 360 randomly selected food crop farmers in eight local government areas spread across the four ADP zones of the State using structured questionnaires. The analytical tools were descriptive statistics involving the use of frequency tables and inferential statistics involving the use of stochastic frontier production function. The result revealed that married female farmers constituted majority (57.22%) of the respondents. Their literacy level was high, as 84% of them had some form of formal education. The respondents cultivate d an average of about two hectares of farm land using personal savings. Eleven cropping systems were identified with mixed cropping accounting for about 53% of the cropping systems and about 54% of the total hectarage allocations. The maximum likelihood estimates of the stochastic frontier production function revealed that farm size, family labour, agrochemicals, inorganic fertilizers and seed contributed significantly to food crop output. The technical efficiency (TE) scores ranged from 0.26-0.96 with a mean TE of 0.66, implying that there is a scope for increasing technical efficiency in food crop production by 34% in the short-run under the current technology. Education, extension contact, crop diversification and credit availability were found to de crease technical in efficiency of the farmers. The study recommended farmers education on fundamental farm management skills to enable farmers plan, evaluate and appraise their farm business activities among others.
