ASSESSMENT OF CLAIMS MANAGEMENT PRACTICES IN THE CASE OF AFRICA INSURANCE SHARE COMPANY- BUSINESS RESEARCH PROJECT
purpose of this study is to assessment of claims management practices in case of AIC. The research’s particular emphasis was given to non-life /general insurance business of the company. The study tried to answer the questions that; what are the main factors of claims settlement dalliance in AIC, how claims management practices are source of customer compliance, how efficient is the claims management practice in AIC and what are the main reasons of claims rejection in Africa insurance company. The general objective of the study is to investigate claims management processes and practices of claims management. The study employed cross-sectional survey design in which 315 external customers selected randomly and 88 internal customers (i.e., staffs) involved in the claim process were the subject of the study by administering specially designed questionnaires. The results obtained suggest that the prevailing claims handling process is a major problem area affecting customers’ satisfaction that need to be overhauled. The clients of AIC believed that lack of updated and clear claims management manuals and procedures, lack of skilled, knowledgeable, experienced and committed claim staff and in claims service are the key challenges in AIC. More importantly, centralized claims management, external and internal effects of immoral behavior of the clients, surveyors, garages, spare part dealers, and internal employees along with sluggish interdepartmental/work units/ communications towards claims management were the major issues in the company. Poor compliant handling system of the company, delay of claims management from notification up to settlement to claimants, lack of intensive standard training for claims staff, and lack of work standard for internal employees, external surveyors and garages decelerates the rate at which quality service is delivered in the company. Thus, it’s recommended based on the finding that the AIC should create an effective, transparent and customer-oriented means to standardize the services, educate the customers, decentralize the claim unit and make use of the standard monitoring mechanism as per the strategies and policies of the company so as to maximize the level of satisfaction of motor claimants. The study suggests that to solve the claims settlement problems should begin from underwriting and the policies should be have an Amharic version and the management should also solve the problems of claims department centralization and dalliance problems. In addition the company should provide timely response for its customers and the investigation process should do in good cooperation with in claims department.

ALTERNATING AND DIRECT CURRENT FLOUSENT TUBE- ELECTRICAL POWER OPTION
An A.C and D.C fluorescent tube is useful for emergency blackout as it works on D.C as well, this saves the production process under lightings.
This project comprises A.C components as well as D.C components under improved conditions, this makes it useful in both urban and rural areas.
When A.C power is off user can supply it with D.C power to light the house or place as well
Although fluorescent lamp is a very efficient lighting device in daily life, still the high harmonic distortion and low power factor cause unnecessary energy consumption. In today’s environment demanding energy efficiency, it is important to reduce this energy loss by integrating an energy saving controller in the electromagnetic ballast of fluorescent lamps. The research presented in this thesis investigates the design and implementation of a new energy saving controller for electromagnetic fluorescent lamp network. The newly developed controller attempts to reduce power losses in both the electromagnetic ballasts and fluorescent lamps by regulating the incoming supply voltage to an optimum level. In addition, the new controller is able to adjust the illuminance level of working environment lightings under either dark or bright condition. Moreover, the function of the new controller is extended with time scheduling control capability, where the switching of lighting systems can be controlled at predetermined times based on occupancy schedule. Both simulation and practical results show that the implemented controller reduces energy consumption by at least 37.5%, by reducing the incoming supply voltage by 15%. In addition, it is desirable to have variable illuminance level control to decrease the energy losses. The experimental results show that the illuminance output level of electromagnetic ballast fluorescent lamps can be decreased by 50% using the new controller while maintaining unity power factor. Integration of the new energy saving controller into electromagnetic ballast fluorescent lamps impressively outperforms the existing electronic dimmable ballast. This new controller brings great ideas for energy saving in the use of fluorescent lamps.

AUTOMATIC 12V PORTABLE BATTERY CHARGER - ELECTRICAL POWER OPTION
The essential use of 12V lead acid batteries in automobile engines to power incorporated electrical appliances, and also the sudden failure of vehicle charging systems that often give rise to a drain of battery cells has necessitated the construction of battery chargers suitable for fully restoring the lost charge into the required 12V battery cells. Most 12V battery charging devices built for commercial services are usually heavy and bulky and lack a protection circuit and a sensitized control circuit required for automatic deactivation of charging once the battery is fully charged. In this new design product, the size of the battery charger was made portable and light in weight to enable end users to convey it as easily as possible. Short circuits and current reverse protection were incorporated as well. A sensitized control circuit was implemented to ensure that charging is terminated immediately when the battery is fully charged. This is to avoid the possible occurrence of overcharging that may result in loss of electrolytes.
In this report the components used to actualize the design work were listed and the design specifications were tabulated with the circuit diagram well detailed. The operational principle of the built charger clearly explains how the design objectives were reached. An adopted formula with example on how to calculate the charging time of a battery when using the product was derived. Design limitations, recommendations, and conclusion were stated. Various relevant tests were conducted with its corresponding results tabulated. Finally, a well labeled image which lays out views of the completely constructed battery charger is attached in order to appreciate the effort and the value of the design work.
(Keywords: AC power supply, rectification, charging, deactivation, full charge)
Considering, the compact shape of the battery charger, with very low ventilation an extractor fan was incorporated to drive away hot air and moisture that would be generated inside the charger compartment during operation.

DESIGN OF POLARITY GUARD FOR AC and DC ADAPTOR - ELECTRICAL POWER OPTION
PROJECT TITILE: POLARITY GUARD FOR AC/DC ADAPTOR
ABSTRACT
The research aims at the designing and implementation of an automatic voltage regulator (AVR) with high precision and hysteresis. The AC power supplied by KPLC (Kenya Power) subjected to variation from time to time.
Moreover, in rural areas supplied voltage remains lower than specified. This causes a considerable threat to the sophisticated electronic device to the computer, refrigerator, television etc. So, ensuring the input voltage to remain in a tolerable pre-specified limit has become a necessity in rural as well as some urban areas. Current system available locally lack precision and suffers the problem oscillating between two output voltage and hence creating surge at the output which can damage valuable electronics. This project handles both shortcomings and introduces the tolerable range of 12 1 voltage output.
MERIT
The circuit is simple but useful for wall AC/DC adaptors where it is important to reduce ripples and noise, and improve transient response of the adaptors. It can also be used in a wide range of switching and analogue power supplies.
The circuit has been developed for 26V and 19V wall adaptors, but by replacing some components, it can be used for other wall adaptors with output voltage starting from 5V. When input polarity is fixed, the bridge can be replaced with simple diodes depending on requirement.
