In microelectronics assemblies, Thermal Interface Materials (TIMs) are vital to the reliability of the devices in operation. Some electronic devices operate in elevated temperature environments such as military and industrial applications. Hence, the need to evaluate the reliability of such devices at elevated temperatures. Tin-Silver-Copper lead-free solder TIMs have been used during the assembly process of some electronic devices operating under harsh temperature environments. In this study, the reliability of SAC305 lead-free solder TIM was considered at elevated temperatures ranging from 100 o C to 200 o C at 25 o C interval, and aged for about an hour. ANSYS finite element analysis software was employed for the design and evaluation of SAC305 lead-free solder model. The findings of the investigation demonstrated that the higher the harsh temperature environment, the lower the reliability of the SAC305 solder TIM. In addition, the highest fatigue life (36735 or 4.2 years) was recorded at 100 o C, while 200 o C recorded the lowest fatigue life (1014 or 0.12 years). The fatigue life is an indication of the lifespan of the TIM when in operation. This research will be beneficial to engineers assembling microelectronic products. Keywords — elevated temperature; fatigue life; microelectronics; reliability; SAC305 solder

Irregular power supply poses a serious problem in many developing countries with power outage usually experienced on a regular basis. Thus, this challenge necessitates the need for an automated method of power change over to an alternative source during power failure that will be an improvement over the manual change over system. This study aims to design and construct a microcontroller-based Automatic Transfer Switch (ATS) for a single-phase system. Atmega8 microcontroller was programmed to automatically switch power supply between a primary source and a secondary power source through the aid of relays. A modular approach was used in the design of this ATS, which incorporates Atmega8 microcontroller, diodes, resistors, L7805 voltage regulator, PC817 optocouplers, a buzzer alarm, NPN transistors, and a Liquid Crystal Display (LCD) that indicates which power source was available. This design is limited to 30A on full loading due to the power relay used in the design. The testing showed that the design was able to automatically switch power between two supply sources with no external aid and it performed optimally even when loaded to 90% of its maximum bearing-capacity. Keywords: Automatic Transfer Switch, Atmega8 Microcontroller, Liquid Crystal Display, NPN Transistors, PC817 Optocouplers, Relays

Rain-induced attenuation of microwaves poses a serious challenge to signal availability beyond 10 GHz frequencies. The challenges are even more pronounced in the subtropical and tropical regions with high intensities of rain which is more accompanied with thunderstorms. Nigeria has an equatorial and tropical climate, which is identified by controlling rainfall. Rain is the significant attenuation factor of various communication signal above 10 GHz frequencies. Therefore, for effective utilization of the microwave bandwidth during rainfall, it is required to form the correlation between this attenuation effect and the bandwidth at various rainfall rate and frequencies at a particular interest location. Therefore , using propagation modelling, the point rainfall and rain effects for frequencies was concurrently considered between 11 and 40 GHz (i.e. Ku, and Ka) for satellite communication service on earth-space path at Ibadan in Oyo state , Nigeria by using rainfall data for the period of five (5) years (January 2014 to December 2019). Keywords- Rain Attenuation, Rain Rate, Bandwidth, Propagation Modelling

This paper assessed the impact of conservation and irrational ridge on phosphorus loss along the riverbank under rainy conditions. To understand the effects, experiments were conducted on farmland with slope gradients of 2%, 3% and 5%. Treatments included groundnut, cowpea, soybean, and no crop: contour and irrational ridge alternated in each runoff block. Standard method was used to calculate phosphorus loss. The results indicated that quantity of phosphorus loss in sandy loamy soils was 4.5 times higher than in loamy sand. In contrast, the phosphorus release (runoff) in loamy sand was 13.52 times higher than in sandy loam, so the average phosphorus loss in soil and surface runoff were 0.4 and 2 Kg / ha / year, respectively. Outcomes proved that the interaction between irrational ridge and vegetation cover increased the phosphorus concentration in the soils than water, thereby reducing aquatic organisms in rivers and creasing health risks for humans. The study recommends that contour cultivation be used very well to reduce phosphorus loss from sediment and runoff. Keywords — Contour and Irrational Tillage, Slope, Cover Crops, Analysis of covariance, Tillage Erosion, River
本文评价了多雨条件下保护和不合理垄对河岸磷流失的影响。为了解其效果，在坡度为2%、3%和5%的农田上进行了试验。处理包括花生、豇豆、大豆和不种植作物:每个径流块的轮廓和不合理的山脊交替。磷损失量采用标准方法计算。结果表明，砂质壤土的磷流失量是壤土的4.5倍。壤土的磷释放(径流)是砂壤土的13.52倍，土壤和地表径流的平均磷损失分别为0.4 Kg / ha /年和2 Kg / ha /年。结果表明，不合理山脊与植被覆盖的相互作用增加了土壤中磷的浓度，从而减少了河流中的水生生物，增加了人类的健康风险。该研究建议很好地利用等高线耕作来减少沉积物和径流中的磷损失。关键词:等高线与不合理耕作，坡度，覆盖作物，协方差分析，耕作侵蚀，河流

The progressively demand on satellite communication systems has consequently resulted in lower frequency bands getting more congested. The usage of frequency band beyond 10 GHz is in focus nowadays as a result of the rapid expansion of radio communication systems. However, Rain is the leading attenuation factor of different communication signal of frequencies beyond 10 GHz. Attenuation due to rain has a significant propagation effect that needs to be carefully considered in satellite communication system network. Rain attenuation predictions and rain rate are essential when planning microwave satellite communication links. A review of the rain rate integration time and rain attenuation models for microwave and millimeter bands satellite system is presented.

The selection of features is used to obtain a subset of features by the removal of irrelevant features with no or less predictive output. Meta-heuristic algorithms are appropriate for the selection of features because feature subset representation is direct and the evaluation is easily accomplished. This paper performed a comparative study on the impact of meta-heuristic optimization algorithms on breast cancer diagnosis using Ant Colony Optimization (ACO) and Particle Swarm Optimization (PSO). The two feature selection algorithms were used to obtain the relevant attributes from the Wisconsin breast cancer (original) dataset. The selected attributes were passed to seven learning algorithms: Support Vector Machine (SVM), Decision Tree (C4.5), Naive Bayes (NB), K Nearest Neighhood (KNN), Neural Network (NN), Logistic Regression (LR), and Random Forest (RF). The diagnostic model was evaluated based on accuracy, precision, recall, and F1-measure. Experimental showed that the highest accuracy of 97.1388% was obtained in both PSO and ACO using RF classifier, the highest precision value of 0.9720 was recorded in ACO using RF classifier, the highest recall value of 0.9750 was achieved in PSO using RF classifier, the highest F1-measure value of 0.9700 was obtained in PSO using SVM, the highest kappa statistic of 0.9370 was obtained in both PSO and ACO using RF and the lowest time of 0s was taken to build a model was recorded in PSO using KNN and NB, and also in ACO using KNN. The paper concluded that the breast diagnostic model using PSO and ACO with different learning algorithms revealed that the accuracy of RF outperformed other algorithms. Also, it was shown that ACO produced better precision using RF compared with PSO and PSO gave better recall using RF compared with ACO, PSO recorded an efficient F1-measure using SVM. The best time used to build a model was obtained in PSO for KNN and NB, and ACO with KNN. Keywords — Breast cancer, Data mining, Diagnosis, Feature selection, Meta-heuristic.
