The future of renewable energy in Africa is at risk at a time when evidences suggest that African continent needs "just renewable energy transition" more than ever before. Many studies have confirmed the benefits of switching to renewable energy.Studies at a global level indicate that renewable energy is the answer to the challenges associated with climate change and a critical step towards attaining climate neutrality. Despite the availability of such evidence, African nations and Nigeria in particular, have done little to ensure that full adoption of renewable energy transition is sufficient to meet current and future energy needs. The need to switch to renewables is expected to grow at a faster rate in Africa......

We have fabricated two different concrete based on fly ash with three different percentage admixture and water repellent dosages. The mortar mixtures were proportioned with cement to sand ratio of 1:3 and 1:4. The important FTIR peaks indicates that the presence of fly ash, and water repellent silicon in concrete mixture. The XRD spectra confirmed that the angle 2θ value with corresponding planes are because of mainly tetrahedrally arranged silicate and octahedrally arrangement of aluminate groups in mixed concrete. The reinforced concretes were cast for the same flow level but different percentages of fly ash (0, 2.5, 5 & 7.5%) dosage. The mechanical study proves that the compressive strength and tensile strength of the concretes increases with increase in fly ash based concrete mixtures up to 5 wt %. However, it is also noted that the admixture significantly enhances the mechanical strength and decreases the early shrinkage of the concrete.

In this study, water base drilling fluids were developed using bentonite clay and rice husk. The pure and blends of bentonite cla1y and rice husk as specified by samples A with (pure rice husk), B (with pure xanthan gum), C (1:1 of rice husk to xanthangum) and D (5:1 of rice husk to xanthan gum) were characterized using X-ray diffraction (XRD) and Fourier Transform Infrared (FTIR). The XRD result of the samples A, B, C, and D Contains Quartz, Halite, Quartz and Quartz respectively with the most intense peak at 2Ө value of 26.642o, 31.578o, 26.624o and 26.627o respectively. The results also shows sample D has less interaction than sample C due to increase in the value of 2Ө at the most intense peak from 26.624o to 26.627o. FTIR results of samples A, B, C, and D shows number of bands/peaks of 13, 12, 14 and 12 respectively. It clearly shows that the high level of interaction between pure and blends of the samples were recorded......

The traditional method of processing locust bean including some other bean varieties is time consuming with lots of energy consumption and labour while mechanical method therefore reduces the human drudgery and also increases output. This research was aimed at modifying an existing locust bean dehuller while carrying out the performance evaluation of the machine using four bean varieties (locust bean, soybean, kidney bean and navy bean) for better efficiency.Some of the components modified in the existing machines include: sieves (to have rectangular and circular form), stainless steel (for dehulling and washing chamber), angle iron (for the machine frame in case of rigidity and stability). The factors considered in the modification of the machine include: cost of the materials, construction technique, availability of materials, durability of materials, cost of maintenance and effect of the materials used on the food ingredients.........

Cyber-attacks are becoming more frequent and severe. When an attack occurs, the attacked enterprise responds with a series of predetermined actions. One of these actions is the use of digital forensics to aid in the recovery and investigation of data from digital media and networks. Cyber Forensic Investigation entails the collection and analysis of digital data to prove or disprove whether an internet-related theft occurred. Previously, computers were only used for storing large amounts of data and performing numerous operations on them, but these days they have expanded and occupied a prior role in crime investigation. The selection and use of forensic tools is critical to solve these cyber-related problems. The developers created it for better research and faster investigation.

Data recovery is crucial in the modern world, where forensics and cyber security are highly sought-after skills. Data recovery steps in when the convict damages or destroys the data storage devices, allowing for the data to be recovered from these artifacts. Many criminals are aware of this field of data recovery, and they constantly try to go around the existing recovery strategies, while organizations constantly look for better and more effective recovery techniques to deal with this issue. This paper focuses mostly on data recovery in cyber forensics and the different tools used to recover data.

Wind energy investment is on the rise. Before installation of a wind turbine, wind power prediction must be performed to estimate the efficacy of the wind power project. Wind speed measurements can only be performed instantaneously from point to point. Currently, these measurement points represent the point where the wind turbine will be installed. These points may not be having the highest wind speed and hence it may not be the optimal points to install the wind turbine. This study will focus on wind power prediction at the points where wind measurement instruments were not installed. This is based on the already existing instantaneous measurements at the site. It is expected that there could be other points with higher wind speeds than the measured points. This paper presents a model for forecasting wind energy. The data was collected using a wireless sensor node using internet of things(IoT). This study gave rise to a machine learning prediction model using time series.

Pattern evaluation is performing on obtained data from different node. Here spatial data obtained as a location of the different cell phone. In the true sense data warehouse is performing on a relational database. Spatial data is need to add in to database. It is challenging to store the spatial data into database. The spatial data is too large in size for storing in data base. And it is very tough to process into data warehouse. Spatial data analysis is challenging task for the data warehouse process. The study is going through the practical working for pattern evaluation on spatial data. The work is also proposing an algorithm to overcome the present issues and achieve accuracy as a process of pattern evaluation.

6G wireless communication systems are expected to operate in terahertzfrequency bands ranging from 0.1-10Thz, with an equivalent wavelength of 3 mm up to 0.03 mm. The terahertz frequency band has high propagation loss, path loss, and atmospheric absorption of molecules.Furthermore, antenna design, fabrication, and measurement at terahertz frequency bands are other challenges for 6G wireless communication applications. Designing a highly directional antenna with a high gain using metamaterials for 6G wireless communication can mitigate the inherent impairments of current 6G wireless communication systems.Metamaterials are artificial shapes that expose electromagnetic possessions and are not regularly found in nature........
