The combination of a fuel cell and batteries has promising potential for powering autonomous vehicles. The MUN Explorer Autonomous Underwater Vehicle (AUV) is built to do mapping-type missions of seabeds as well as survey missions. These missions require a great deal of power to reach underwater depths (i.e., 3000 meters). The MUN Explorer uses 11 rechargeable Lithium-ion (Li-ion) batteries as the main power source with a total capacity of 14.6 kWh to 17.952 kWh, and the vehicle can run for 10 hours. The drawbacks of operating the existing power system of the MUN Explorer, which was done by the researcher at the Holyrood management facility, include mobilization costs, logistics and transport, and facility access, all of which should be taken into consideration. Recharging the batteries for at least 8 hours is also very challenging and time consuming. To overcome these challenges and run the MUN Explorer for a long time, it is essential to integrate a fuel cell into an existing power system (i.e., battery bank). The integration of the fuel cell not only will increase the system power, but will also reduce the number of batteries needed as suggested by HOMER software. In this paper, an integrated fuel cell is designed to be added into the MUN Explorer AUV along with a battery bank system to increase its power system. The system sizing is performed using HOMER software. The results from HOMER software show that a 1-kW fuel cell and 8 Li-ion batteries can increase the power system capacity to 68 kWh. The dynamic model is then built in MATLAB/Simulink environment to provide a better understanding of the system behavior. The 1-kW fuel cell is connected to a DC/DC Boost Converter to increase the output voltage from 24 V to 48 V as required by the battery and DC motor. A hydrogen gas tank is also included in the model. The advantage of installing the hydrogen and oxygen tanks beside the batteries is that it helps the buoyancy force in underwater depths. The design of this system is based on MUN Explorer data sheets and system dynamic simulation results.

Hydro-Electricity and Solar Power are environmentally friendly renewable sources of energy that utilize the potential energy from dammed water and the sun respectively to generate electricity. In this paper is reported a new design and implementation of combining solar and hydro-electric power. The turbine and gearbox system used in this design is fabricated from scarp parts of used appliances. The hydro head of the Pico-Hydro plant commissioned was 5m which accumulated a hydraulic potency of the stream of about 5.886kW. The prime mover of the generator consisted of a modified crossflow turbine that is coupled with a gearbox to amplify the rpm of the system. A 500W synchronous generator was driven by the prime mover to generate raw phase shifted AC power. This raw power was rectified with a 25 A full wave rectifier and used in conjunction with 12 V 400 AH deep cycle battery bank system to supply power to a newly furnished double storey house. The generator output through the full wave rectifier is connected to a load controller for optimal charge efficiency. The load controller is connected to the battery bank through a Programmable Logic Controller (PLC). The PLC activates a dummy resistive hot water element when the battery bank is fully charged. The Arduino GSM module monitors the entire process and automatically sends notification via a SIM interface to the system administrator notifying the system administrator of the on/off state of the heating element.

This paper describes a general data base management package, devoted to medical applications. SARI is a user-oriented system, able to take into account applications very different by their nature, structure, size, operating procedures and general objectives, without any specific programming. It can be used in conversational mode by users with no previous knowledge of computers, such as physicians or medical clerks.As medical data are often personal data, the privacy problem is emphasized and a satisfactory solution implemented in SARI.The basic principles of the data base and program organization are described ; specific efforts have been made in order to increase compactness and to make maintenance easy.Several medical applications are now operational with SARI. The next steps will mainly consist in the implementation of highly sophisticated functions.

A project for the long-term strategy of Russian break-through into post-industrial society is suggested which is directed at transformation of the hi-tech complex into the leading factor of economic development. The thesis is substantiated that there is an opportunity to realize such a strategy in case Russia shifts towards the mechanism of the monetary base growth generally accepted in developed countries: the Central Bank increases the quantity of "strong" money by means of purchasing state securities and allocates the increment of money in question according to budget priorities. At the same time for the realization of the said strategy it is necessary to partially restore savings lost during the hyperinflation period of 1992-1994 and default of 1998 and to secure development of the bank system as well as an increase of the volume of long-term credits on this base.
