Typically, the teacher calls names and writes them down. This approach has a number of drawbacks because when recording their attendance, students are diverted from the presentation and may register for absent classmates. The smart attendance solution suggested in this study allows students to tap their student identity (ID) card on a near field communication (NFC) reader, streamlining the attendance procedure by using near field communication (NFC) technology. The technique is affordable, effective, and simple to keep up. Automating student attendance saves time and alleviates anxiety. The average time for the NFC system to take a student's attendance is 3.5 seconds, compared to 16 seconds for the conventional method. The inaccuracy associated with recording attendance is reduced by 31% thanks to NFC technology. The numerical results of the NFC-based scheme are compared with the traditional scheme and observed that the proposed scheme outperforms the conventional scheme.

This calls for the need to adopt new technologies to ease mobility problems among visually impaired victims. It was estimated in the year 2009 that there exists 160 million blind and partially visually impaired people worldwide. This paper focuses on an embedded system adaptive technology to reduce navigation challenges being encountered among visually impaired people using sensorial and communication IT functionalities with an affordable cost as an efficient navigation tool. In this research, an ultrasonic sensor, microcontroller, buzzer, electrolytic capacitor, oscillator, and other hardware components were used to detect obstacles thereby sending vibration notification warning sound to the blind and keep them from hitting or getting to the point of obstructions / accident lying ahead.

The optical properties of the material (gold) such as dielectric function are employed and modelled i.e., the frequency-dependent dielectric function as well as other optical properties through the quantummechanical approach to visualise the behaviour of the real-and imaginary parts of the optical properties (dielectric function) of the material of interest. The essential equations and its associated supplementary variable equations are neatly analogous with the starting point being Maxwell's equations. This is a justification that demonstrates the visceral uniformity and flexibility of the calculated supplementary, essential and diagonalised forms from Maxwell's equations.

Further dehydration and subsequent dehydration at low-temperature dehumidification were conducted in fabricated equipment using sliced pawpaw (Carica papaya L) as fruit sample. The samples were dimensioned2cmin width by 20 cm in length and were treated at optimal conditions of 50 o C temperature, 60 o Brix sucrose concentration for 3 hours of immersion in a pilot-scale plant. The osmotically treated samples were further dehydratedconventionally in a fabricated dehydratorwith and without a de-humidification Chamber, bothoperated at 60 o C until consistent weights of samples were achieved. The effect of dehumidification was studied on the samples. The appearances of samples without dehumidifierwere golden browns in colourand the textures crispywhile the dehumidified sample retained the golden yellowandwas leathery to touch. The Physico-chemical analysis of the processed samples revealed retention of nutritional properties. Dehydrator equipped with dehumidifier reduced the water content in the samples at a faster rate to attain constant weight at about 400 hrs when compared with 550 hrsof treatment without dehumidification to attain relatively constant weights that is suitable for storage and packaging of treated samples.

The simulation of the models were carried out at varying the band gap and thickness of the absorber layer and subsequently formulate model equation using regression analysis to determine the efficiency and fill factor at any given value. Result shows that increase in the thickness absorber layer of this structure gives fill factor, current density and open voltage increases from 83.74-84.77, 26.26-28.85mA/cm2, 0.71-0.73, 15.51-17.82% that ultimately resulted in a high efficiency of solar cell while increase in band-gap of the absorber layer reduces efficiency of the solar cell. Model equation gives errors ranges between 0.026 – 0.4 for thickness and efficiency, 0.0068 – 0.078 for thickness and fill factor and 0.003 – 0.2 for band gap and efficiency. The study shows that large thickness of absorber layer and low band gap favour the optimization and model equations can be used to estimate/forecast the efficiency and fill factor within the limit of the variable parameters and this offers better direction for laboratory experiment

However, this prediction is necessary for link budget and in the determination of the coverage area of a particular base station. Therefore, in this paper, a fuzzy-logic based path loss prediction model is proposed for accurate link budget and optimal coverage determination. Also, a drive test is conducted and data were collected for non urban, urban, suburban, ex-urban, dense-urban, micro-urban and peri urban areas in Lagos metropolitan environment for training the proposed model. Network parameters were varied during the performance evaluation process for the 900MHz and 1800MHz bands. Results show that the mean path loss for different environments is higher for the 900MHz band compared with 1800MHz band and this shows that propagation in the 900MHz environment is characterized with more challenges and dynamic propagation conditions than in 1800MHz. Additionally, the urban environment gives the highest value for the constant offset being 60dB for 900MHz but the ex-urban environment has a constant offset of 64dB in 1800MHz.
