GaN-based Semiconductor devices with Multichannel Structures
Full text linkSemiconductor junctions, for example, pn-intersection and Schottky intersection have been very significant as essential components for different semiconductor gadgets. The break-down voltage of the junction PN-intersection relies upon the polluting influence fixations in semiconductors. An opposite voltage is supported in the exhaustion layer thickness which is corresponding to the square of base voltage. The breakdown happens, when the electric field with an intersection arrives at the semiconductor regardless of whether the consumption layer can be extended substantially. To accomplish higher go down voltage, a wide band hole semiconductor, for example, silicon carbide has been examined. The electron gadgets utilizing silicon carbide may undergo serious issues. In any case, the breakdown system of the intersection utilizing silicon carbide is as yet equivalent to that of the conventional junctions. As of late, GaN utilized electron gadgets have developed as cutting-edge high force exchanging gadgets inferable from their high breakdown field. A few papers have revealed that GaN-based HFETs is directly expanded by expanding the junction dividing between the door and channel electrodes. This conduct is unique in relation to that of the customary junctions
Compressive Strength Properties of Cassava Peel Ash and Wood Ash in Concrete Production
Full text linkHigh rate of increase in the prices of cement is worrisome and become burden to people in the entire construction industry. Researchers, civil engineers, builders, architects and all concerns parties in the building industry are desperate for any suitable and effective but cheaper materials that can replace cement. There is need to find an alternative binding material that can be used mainly or in partial replacement of cement. The materials used were sourced from Bida town, Niger state, Nigeria. Wood ash and cassava peel ash were obtained after burning in the furnace at National Cereal Research Institute Badeggi, Bida into ash and passed through 75 micro meter sieve to the finest texture. The water use for the work was free from impurities. The comparative study on the compressive strength of concrete when OPC was partially replaced independently by some percentage of cassava peel ash (C.P.A) and wood ash (W.A) using 0%, 5%, 10%, 15%, 20% and 25% on both materials, 0.5 water-cement ratio and mixed design ration of 1:2:4. The mean strength of concrete at control is 0% (27.11N/mm2), 5% (24.44N/mm2), 10% (23.25N/mm2), 15% (23.36N/mm2), 20% (18.52N/mm2) and 25% (15.93N/mm2). 25% replacement of cement has the lowest mean strength at 28 days. Replacement at 5, 10 15% are within specification of (20N/mm2) for plain concrete while 20 and 25% are not suitable for structural concrete. The higher the pozzolanic material added to the cement in concrete production the lower the strength. The effects of Cassava Peel Ash and Wood Ash as environment pollution can be reduced when utilized as part of cement in concrete production

Business Security Design Improvement Using Digitization
Full text linkIn this simulation study, the facilities were not crowded. The reading environment in these businesses was also observed to be promising in such a way that they were marked by good lighting, minimal noise, and adequate ventilation. Another physical aspect concerned the stock of books. In particular, the businesses displayed a state of variety whereby these books were arranged based on the broad and specific subjects to which they belonged. The use of technology was another dominant feature in the three businesses and this trend can be linked to the pressure towards keeping abreast with changing technologies and the evolution of business user demands in these institutions. Apart from the availability of books in physical form, sections of the copies were available in the soft copy and this feature was pronounced in the case of the high business center. The businesses were also different in terms of the overall physical sizes but this attribute could be attributed to the differences in the expected number of users. For example, the middle school and high school businesses were larger compared to the elementary business center visited but this outcome could be explained by the smaller number of business users in the selected elementary school. Hence, it can be inferred that the expected number of users dictates the overall and physical size of a business center

Cloud Computing Security Optimization via Algorithm Implementation
Full text linkThere has been a growing need for significant improvements in cloud computing security ? to ensure that operations and data interactions in the cloud keep abreast with the dynamic nature of information technology. Motivated by the quest for cloud computing security, this paper has examined different approaches that most of the previous scholarly investigations (which focus on the adoption of machine learning in cloud computing security) have proposed ? towards better threat detection. The paper has begun with a general algorithm responsible for establishing the summation of risk levels before proceeding to more advanced algorithms through which threats to cloud data could be determined. Imperative to note is that the advanced approaches have been found to embrace anomaly detection and signature detection, translating into a proposed hybrid model for threat detection in the cloud. Whereas a major weakness is that the proposed model is not compared to another competitive model, its strength lies in the capacity to give an insight into ways in which certain time frames and profile categories could be specified, leading to a better classification of cloud user profiles and the eventual detection of anomalies

Thermal Property Investigation in Nanolubricants via Nano- Scaled Particle Addition
Full text linkIn nanolubricants, the increase in scholarly attention has been attributed to the affirmation that they exhibit enhanced thermo-physical features and that they can also be used in various thermal applications. Some of these applications where they could be incorporated include solar energy harvesting, industrial applications, and heat exchanger effectiveness enhancement. Recently, various approaches have been employed to enhance the coefficient of heat transfer, especially between the fluid contact surfaces and the working fluids. When it comes to conventional fluids of heat transfer, examples being ethylene glycol/water, thermal oils, and water, some studies document that they exhibit limitations. For instance, these fluids exhibit low thermal properties when compared to the solids with which they interact. To respond to this dilemma, there have been efforts in this study to have the fluids’ thermal properties improved via nano-scaled particle addition, causing marked evolutions in the evaluations of the behavior of fluids of heat transfer. Indeed, findings suggest that in base fluids, when the solid particles are suspended, there tends to be an enhancement in the fluid’s energy transmission; hence, notable improvements in material thermal conductivity properties, besides the betterment of material heat transfer characteristics
