Abstract The healing of fractures can be monitored using electrical current across the wound. Over a period of seven years, 32 fracture patients, group 1 comprising of 20 patients and group 2 of 12 patients were studied. Group 1 was electrically stimulated while group 2 was not electrically stimulated. The process of healing was monitored as current versus number of days.... The healing of fractures can be monitored using electrical current across the wound. Over a period of seven years, 32 fracture patients, group 1 comprising of 20 patients and group 2 of 12 patients were studied. Group 1 was electrically stimulated while group 2 was not electrically stimulated. The process of healing was monitored as current versus number of days. The current stabilized after the union of fracture. The data was subjected to regression analysis and fitted to a FOPDT model with an error of less than 5%. An ANOVA analysis of the two groups indicated an F ratio which suggested that results are significant. Read More Read Less

Abstract There is a plethora of silicon options available for implementing the various functions of a transmitter, but FPGAs are an attractive alternative for many of these tasks due to performance, power consumption and flexibility.

There is a plethora of silicon options available for implementing the various functions of a transmitter, but FPGAs are an attractive alternative for many of these tasks due to performance, power consumption and flexibility. This paper presents a complete hardware architecture for transmitter which is then synthesized and mapped on the Spartan 3E FPGA kit. The transmitter carries out data formatting, NRZ line encoding, baseband modulation, pulse shaping and passband modulation. A ROM based raised cosine filter is designed to mitigate the effects of Inter-symbol Interference. Passband modulation is accomplished by designing hardware using Direct Digital Synthesizer. A dedicated module to introduce channel imperfections is also designed to study the behavior of transmitter on practical interfaces. The implemented subsystem is particularly suited for use in a typical WiMAX environment or any other SDR based system that performs downstream digital signal processing. Read More Read Less

Our objective is to develop an information system automated for the management of production of the electrical energy from the solar energy. This system consists of two softwares. The first one is a mobile application which communicates with a remote server in which is stored a database memorizing all the information of the process of electric production from the solar energy. This information concerns the production of the solar equipments installed at the customers and also the possible complaints declared by the appearance of an incident noticed on the equipment. The second application is installed on the server, has for role to communicate with its equipments via internet to get back all the data of production shown by inverters. These data got back since equipments solar (inverters) will serve to update the database of the server. The application of the server has the capacity also to generate alerts further to an electric production on an inverter not in compliance with the normal state. The database will be remotely exploited by the first mobile application to consult at a distance the state of these equipments, the possible complaints of the customers, the curves of productions of energies of these equipments, refreshment of the local data with the data of the server etc...

This paper presents a hardware implementation of the same algorithm on an FPGA board by designing the complete architecture and successfully mapping it on Xilinx Spartan 3E after thorough functional verification. The results show that this implementation provides a very efficient single-precision floating point inverse square root calculator with a practically accurate result being made available after just 12 short clock cycles. This performance measure is far superior to the software counterpart of the algorithm, and is not processor dependent like rsqrtss of x86 SSE instruction set. Results of this work can aid FPGA based vector processors or graphic processing units with 3D rendering. The hardware design can also form part of a larger floating point arithmetic unit for dedicated reciprocal square root calculations. Read More Read Less
