Abstract Ashesi University College recently acquired a TurtleBot1 robotic platform to experiment with service robotics on campus. This platform runs the Robotics Operating System (ROS)2 for developing robotics applications. This MOLAM project (Motion, Localization And Mapping) sought to build a fundamental framework that extends ROS functionalities on a TurtleBot to navigate autonomously around the Ashesi campus in Berekuso. The focus of this project was to extend the ROS enabled functionalit...
ABSTRACT Fura is a millet-based spontaneously fermented dumpling produced and consumed in parts of West Africa, particularly Nigeria, Burkina Faso and Ghana. From eight (8) traditional fura production sites in northern Ghana, lactic acid bacteria (LAB) and yeasts were isolated, characterized and identified using genotypic methods. These included (GTG)5-based rep-PCR fingerprinting, sequencing of the 16S rRNA gene, multiplex PCR by means of recA gene sequence comparison and sequencing of D1/D2...
This project involves the use of an inductive sensor to control a robotic arm system. The signals generated in the induction coil will help in controlling the manipulator to perform certain gripping and grabbing actions. Also, the report describes the method used to acquire and process these induced signals before they are sent (induced signals) to the manipulator through the help of two programmed microcontrollers.
ABSTRACT The physiological monitoring device is use to detect patient vital signs during treatment. It measures the rate a person that performs routine activities. The device detects body posture and activities that are of significant interest in applications such as sports, medicine, and military training. The study uses design of wireless controlled physiological monitoring device using ATMEL microcontroller. The physiotherapy is performed by a designed robotic arm fixed to the patie...
ABSTRACT Nunu is a spontaneously fermented yoghurt-like milk product consumed as a staple food commodity invirtually all parts of the Country. Its production and consumption gives way to much food security and economic benefits to the rural people. However, the process characteristics result in products which are not appealing to many people, have very short shelf-life and could have food safety concerns. In a framework of research to improve the product quality and increase consumption, a st...
This study was carried out to develop probiotic fermented beverages. The commercial strain Bifidobacterium infantis 20088 was used. The growth of the strain and its related physiochemical changes during fermentation was evaluated. The strain survival during refrigeration storage was also examined. In addition the chemical composition of different fermented beverages at initial and maximum growth of the strain were also determined. Growth media were formulated from reconstituted skim mil...
Abstract Designing and controlling a robotic arm with great performance is one of the fields of interest in many applications. This thesis is concerned with the problems control of robot arm (mentor) using Proportional Integral Derivative (PID) controller for axis1 (shoulder) and axis2 (elbow). The research work was undertaken in the following developmental stages; first stage, estimation of the transfer functions of Direct current (DC) motors actuators of tow axis’s using system identific...
Abstract Synthetic biology is the engineering of biology; it is the evaluation and design of biological systems in a rational and systematic manner. It blurs the lines between various science and engineering disciplines due its numerous applications, with one of the most significant being the use of biosensors in environmental remediation. Biosensors substitute engineered microorganisms as traditional sensors and transducers. In recent years, the use of E. coli as the primary micro-organism i...
ABSTRACT Foods and vegetables belong to an important class of natural products with capacity to exert therapeutic effects – due to presence of phytonutrients. A phytonutrient is any non – toxic food component that has scientifically proven health benefits, including diseases prevention and treatment. This article focuses on about 40 Natural products (fruits, vegetables, spices) which includes Water melon (Citrulus lanatus), Apple (Malus domestica), Pawpaw (Asimina triloba) and Banana (Mu...
Abstract: Background: Symbiotic interactions between insects and bacteria have been associated with a vast variety of physiological, ecological and evolutionary consequences for the host. A wide range of bacterial communities have been found in association with the oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), an important pest of cultivated fruit in most regions of the world. We evaluated the diversity of gut bacteria in B. dorsalis specimens from several populati...
ABSTRACT The usefulness of non-steroidal anti-inflammatory agents in the management of rheumatoid diseases cannot be over-emphasized. As this disease is characterized by chronic inflammation, it is usual to test compounds for anti-inflammatory activity in animals and then hope that the active ones should be clinically useful as anti-rheumatic drugs, From the literature, non-steroidal anti-inflammatory agents have covered a wide range of chemical structures aryl acetic, aryl-propionic, arylbu...
ABSTRACT In most developed countries such as United States of America France and China hotel business has become more sophisticated then it was a decade ago. The world today has taken a new dimension as long as business is concerned. It has become much more smaller than it was in the days of legendary Christopher Columbus Vasco D Agan and Fedinand Magilan then it took a whole life fortune and year to travel from one continent to another. But today it is a matter of closing your eyes and...
Abstract Picking and placing an object or products in specific place or boxes play an important part in industry process, it consumed a lot of time also need patience and accuracy and cannot handle any mistakes. Pick and place robot is a robot that can be programmed to pick product or any object and place it somewhere. these robots are popular among many automation applications and material handling system, they are especially practical in applications where repetitive and difficult tasks ne...
ABSTRACT This work improves upon the Potential Field Method (PFM) for the navigation of autonomous mobile robots, through the introduction of a new Hybrid Virtual Force Field (HVFF) concept. The HVFF concept integrates the virtual force field (VFF), which is based on the principles of artificial attractive and repulsive potentials, with the virtual obstacle concept (VOC) and the virtual goal concept (VGC). In particular, the specific challenges resolved by the HVFF include the local minimal p...
Abstract: Tephritid fruit flies are among the most destructive pest species of fruits and vegetables in many regions of the world. Apart from high losses in yield, tephritid fruit fly pests pose great socioeconomic and ecological challenges as well as demand effective measures to curb infestation which can be costly. Among currently used management options are the use of chemical insecticides, behavioral, genetic, cultural and biological approaches. However, no single method or combination o...
