The forecast of electricity demand in India is of considerable interest since the electricity sector has been the prime focus of past as well as present Governments. This study presents three models of prediction of electricity demand of New Delhi, namely Multiple Regression, Trend Seasonality Model and ARIMA modelling. The significance of climatic and seasonal factors on electricity demand as well as comparison of the relative accuracy of the models have also been discussed
The study examined the impact of school location `on academic achievement of Science Students in Senior Secondary School Certificate Examination. The purpose was to determine whether the geographical location has any impact on the achievement of the students in Biology, Chemistry and Physics. The design adopted for the study was an ex-post facto of survey type. The targeted population for the study was Senior Secondary III (SS III) Physics students of public secondary schools in Ekiti West Local Government Area of Ekiti State, Nigeria.

This paper presents the generation of optical carrier suppressed signal for RoF system. RoF refers to an analog transmission over fiber technology where light is modulated by radio frequency (RF) signal and transmitted over an optical fiber link to wireless access. Both optical carrier suppression and signal modulation are made by using a Dual-Drive Mach-Zehnder modulator (DD-MZM). Suppressed carrier modulation is achieved by biasing at the null point of DD-MZM. Optical carrier suppression improves the performance of RoF system such as link gain and noise figure (NF).In this research, a single RF at 2100 MHz having data rate of a 1 Gbps modulates the 1550.12 nm optical carrier in the DD-MZM. In this paper, the carrier suppression and performances of RoF system are investigated by theory and simulation. The various values of optical carrier suppression ratio can be obtained by adjusting the extinction ratio of the DD-MZM.
The Z-Source concept has many advantages and can be applied for any type of power conversion. Both boosting and modulation index can be controlled in inverter operation itself, by inserting proper shoot through states. This paper presents procedure for implementing, space vector modulated REC Zsource inverter in MATLAB SIMULINK by inserting shoot through states. It also explains a clear procedure of selection of shoot through states at required time and presents an overall tabular column of the sequence of switching states for three level space vector modulation. The proposed techniques are demonstrated in MATLAB and have achieved good performance results.
In this paper a new scheme is proposed for progressive image transmission over coded Orthogonal Frequency Division Multiplexing (OFDM) system with Low Density Parity Check Coding (LDPC). Trigonometric transforms are used in this scheme for improving the performance of the OFDM systems and reducing the PeakTo- Average Power Ratio (PAPR) of OFDM signal. It improves the error resilience ability and transmission efficiency for progressive image transmission over Additive White Gaussian Noise (A WGN) channel. The Set Partitioning In Hierarchical Trees (SPIHT) algorithm is used for source coding of the images to be transmitted. In the proposed scheme the transmit data sequence of the OFDM signal after Inverse Fast Fourier Transform (lFFT) is grouped into in-phase and in-quadrature components, then each component is transformed using either the Discrete Cosine Transform (DCT) or the Discrete Sine Transform (DST). The simulation results show that adding the DST to the system im
Variations in root and root canal is always a challenge and failure to recognize these variations can result in unsuccessful endodontic treatment. Mandibular molars can sometimes present a variation called radix entomolaris, wherein the tooth has an extra root attached to its lingual aspect. This additional root may complicate the endodontic management of the tooth if it is misdiagnosed or maltreated. The case reports in the present article focus on the radiographic identification and endodontic management of Radix Entomolaris in permanent mandibular first molars.
Looking different from everybody does not only depend on the way you dress or the way you carry yourself; it also depends on the type of jewelry you are wearing. If it is diamond unique jewelry, it will not only bring about a different glow to your face, it will also make you look especially classy.
