Abstract:
E-Government is the use of information and communication Technologies (ICT) such as internet, smart phones, telecommunication, mobile company among others to interact between government and the citizens in running the affairs of the country such as decision making etc. The impact and potential of ICTs have not been fully exploited in the Nigerian context, leaving government in a weak position to formulate policy comprehensively and implement plans effectively. Despite the fact that E-government has been implemented for a while now in Federal Capital Territory (FCT) of Nigeria Abuja, but its effectiveness is not impressive. The citizens connection to the government is limited it can be improved more easily using electronic means of communication, A reduction in corruption cases as accountability and transparency can also be increased, Equal opportunity will be given to all to access information irrespective of the person’s physical location or disability and the elimination of the bureaucracy experienced in government offices. This research work is aimed at assessing the effectiveness of e-government in federal capital territory of Nigeria Abuja using Seoul Metropolitan Government as a yard stick for measuring the effectiveness. Questionnaire was used as a primary method of data collection, internet and library as secondary data. The data obtained from the questionnaire has been analyzed using frequency table and percentage. The findings of this work shows that 41.91% of the respondents agree e-government initiatives have decreased civil servants corruption in Abuja, 46.81% of the respondents agree that E-government services has increased citizens trust in Abuja, 58.11% of the respondents believe that E-government initiative have increased the accessibility to the government in Abuja however 37.11% agree that Lack of IT infrastructure is the major problem affecting E-government in Abuja.

Abstract:
In this paper, nonlinear vibration of electrostatically actuated microbeam is analyzed using differential transformation method. The high level of accuracy of the analytical solutions of the method was established through comparison of the results of the solutions of exact analytical method, variational approach, homotopy analysis method and energy balance methods. Also, with the aid of the present analytical solution, the time response, velocity variation and the phase plots of the system are presented graphically. It is hope that the method will be widely applied to more nonlinear problems of systems in various fields of study.

Abstract:
We live in a connected world of digital devices which include mobile devices, workstations, control systems, transportation systems, base stations, satellites of different interconnected networks, Global positioning system (GPS) with their associated e-services in which internet provide platform for the connection of this devices worldwide. cyber forensics as a sub-branch of computer security that uses software and predefined techniques which is aim at extracting evidences from any form of digital device and can be presented to a court of law for criminal and/or civil proceedings provided that it satisfy this three conditions; comprehensiveness, authenticity and objectivity. Cyber space is recently considered a domain worth exploring and investigating and securing after lithosphere, hydrosphere, biosphere and atmosphere. Cyber threats, attacks and breaches have become a normal incident in day-to-day life of internet users. However, it is noted that cybersecurity is based on confidentiality, integrity and validity of data. In this research work machine learning algorithms applied to cybersecurity and cyber forensics are clearly explored and pave away for further research directions on the application of deep learning, computational intelligence, soft computing to cybersecurity and cyber forensics.

Abstract:
Due to the complexity of data, interpretation of pattern or extraction of information becomes difficult; therefore application of machine learning is used to teach machines how to handle data more efficiently. With the increase of datasets, various organizations now apply machine learning applications and algorithms. Many industries apply machine learning to extract relevant information for analysis purposes. Many scholars, mathematicians and programmers have carried out research and applied several machine learning approaches in order to find solution to problems. In this paper, we focus on general review of machine learning including various machine learning techniques. These techniques can be applied to different fields like image processing, data mining, predictive analysis and so on. The paper aims at reviewing machine learning techniques and algorithms. The research methodology is based on qualitative analysis where various literatures is being reviewed based on machine learning.

Abstract:
In this work, the thermal behavior of fin made of palladium material under the influences of internal transfer mechanisms such as thermal radiation and temperature-dependent internal heat generation is investigated. The thermal model for the extended surface made of palladium as the fin material is first developed and solved numerically using finite difference method. The effects of various parameters on the heat transfer model of the extended surface are investigated. The results show that the rate of heat transfer through the fin and the thermal efficiency of the fin increase as the thermal conductivity of the fin material increases. This shows that fin is more efficient and effective for a larger value of thermal conductivity. However, the thermal conductivity of the fin with palladium material is low and constant at the value of approximately 75 W/mK in a wider temperature range of -100oC and 227oC. Also, it is shown that the thermal efficiencies of potential materials (except for stainless steel and brass) for fins decrease as the fin temperatures increase. This is because the thermal conductivities of most of the materials used for fins decreases as temperature increases. However, keeping other fin properties and the external conditions constant, the thermal efficiency of the palladium is constant as the temperature of the fin increases within the temperature range of -100oC and 227oC. The study will assist in the selection of proper material for the fin and in the design of passive heat enhancement devices under different applications and conditions.

Abstract:
In this study, the effects of internal heat generation on thermal performance of porous fin is theoretical investigated using differential transform method. The results of the developed analytical solutions are verified numerically and analytically using Runge-Kutta method coupled with shooting method and Galerkin weighted residual method, respectively. The parametric studies reveal that as the porosity parameter increase, the rate of heat transfer from the base of the fin and consequently improve the efficiency of the fin increase. Increase in the internal heat generation leads to increase in the value or the range of the thermal stability of the fin. However, a high value or an excessive internal heat generation results in an undesirable situation where some of the heat energy cannot escape to the sink and instead ends up flowing into the prime surface and the fin tends to store heat rather than dissipating it. This scenario defeats the prime purpose of the cooling fin. Therefore, the operational parameters must be carefully chosen to ensure that the cooling fin retains its primary purpose of removing heat from the primary surface.

Abstract:
Detecting the presence of a valid signal is an important task of a telecommunication receiver. When the receiver is unable to detect the presence of a valid signal, due to noise and fading, it is referred to as an erasure. This work deals with the probability of erasure computation for orthogonal frequency division multiplexed (OFDM) signals used by multiple input multiple output (MIMO) systems. The theoretical results are validated by computer simulations. OFDM is widely used in present day wireless communication systems due to its ability to mitigate intersymbol interference (ISI) caused by frequency selective fading channels. MIMO systems offer the advantage of spatial multiplexing, resulting in increased bit-rate, which is the main requirement of the recent wireless standards like 5G and beyond.

Abstract:
Many organizations are struggling to provide high bandwidth and reliable internet connectivity at their branch offices and business locations and getting the most out of their operational expense. The need for internet connectivity at any branch offices and business locations is not a luxury anymore but is a necessity. Let us try to understand how to plan and document the SDWAN (Software Defined- Wide Area Network) implementation in an organization. We will try to understand why it is essential to implement the new technology instead of investing in the existing MPLS (Multi-Protocol label switching) by taking an example of a retail organization.

Abstract:
Copper Zinc Antimony Sulfide (CZAS) is derived from Copper Antimony Sulfide (CAS), a famatinite class of compound. In the current paper, the first step for using Copper, Zinc, Antimony and Sulfide as materials in manufacturing synchrotronic biosensor–namely increasing the sensitivity of biosensor through creating Copper Zinc Antimony Sulfide, CZAS (Cu1.18Zn0.40Sb1.90S7.2) semiconductor and using it instead of Copper Tin Sulfide, CTS (Cu2SnS3) for tracking, monitoring, imaging, measuring, diagnosing and detecting cancer cells, is evaluated. Further, optimization of tris(2,2'–bipyridyl)ruthenium(II) (Ru(bpy)32+) concentrations and Copper Zinc Antimony Sulfide, CZAS (Cu1.18Zn0.40Sb1.90S7.2) semiconductor as two main and effective materials in the intensity of synchrotron for tracking, monitoring, imaging, measuring, diagnosing and detecting cancer cells are considered so that the highest sensitivity obtains. In this regard, various concentrations of two materials were prepared and photon emission was investigated in the absence of cancer cells.
