Abstract: In this paper, based on a new multiplication of fractional analytic functions, we solve a fractional algebraic equation. The solutions of this fractional algebraic equation can be obtained by using some methods. In fact, the solutions are generalizations of the traditional algebraic equation solutions.

Abstract: This article delves into the geometry-impedance relation of the three-phase squirrel cage induction motor (SCIM), to study the levels of sensitivity of the impedance parameters to design modifications in the geometry of the rotor bar cross section. Studies have long clarified the facts about the strong influence that the geometry of the rotor bar transverse section has on the standstill and operating impedance values of the rotor circuit, and it is a well-known fact that the development of electromagnetic torque as well as the shape of the torque-speed characteristic of the SCIM are all to a large extent dependent on the rotor circuit impedance. During design and optimization routines, the design engineer usually leverages on the aforementioned facts to accomplish a successful torque optimization program. Barring the saturation of the leakage flux path during large slip motoring operation, the magnitude of the rotor leakage reactance is usually greater than that of the rotor resistance, but the result of this study shows that the relative sensitivity of this reactance to design changes in the geometry of the rotor bar cross section, appears inferior.

Abstract: Social engineering is one of the most common attacking threats to the Mobile Money users during money Transactions. With the increasing rate of mobile money use, it has directly increased the number of social engineering incidents in mobile money services. It is therefore important to come up with the guidelines that will help the society to be more aware and to reduce the mobile phone criminals. As of now, some customers and other Mobile money users like agents have already lost thousands of shillings due to social engineering attacks.

This study assesses the mobile money user’s perception on social engineering. The primary data were used and collected by a questionnaire method of 407 populations with the 203 sample size, analyzed by using the SPSS tool and it is a descriptive analysis. Few of the reason founded that lead in social engineering attacks are as lack of security awareness, PIN sharing, PIN requests and storing PINs in address books were recognized as major sources of vulnerability in mobile money theft. The study revealed that, mobile money users level of awareness on social engineering were good and is caused by the good perceptions of the Mobile Money users  in the extents that many of them use their Mobile Money accounts in a safe environmentsin the consideration of knowledge, behavior and the security metrics.

The study recommends that mobile money service provider, government and the normal Mobile Money users each have to play the role on fighting against social engineering attacks, like service provider to make security awareness program to the Mobile Money users has to make sure that the security and privacy policy are surely practiced. Furthermore normal Mobile Money users are advised to acquire professional knowledge, get educational trainings and form strong collaboration to fight against cybercrimes in general and social engineering particularly.

Abstract: Based on Jumarie type of Riemann-Liouville (R-L) fractional derivative, this paper provides some examples to illustrate how to use fractional power series to solve fractional differential equations. Chain rule and product rule for fractional derivatives and a new multiplication of fractional power series play important roles in this paper. In fact, our results are generalizations of the results of ordinary differential equations.

Abstract: This study evaluated ergonomic hazards faced by control room workers in selected oil and gas establishments in Delta and Rivers states. The study focused on data collected from 110 operators in control rooms using a self- administered questionnaire. Data gathered from the study were analyzed with descriptive statistics. The results showed considerable work station ergonomic deficiencies which included lack of rest breaks, absence of display screen antiglare, lack of foot rest, uncomfortable cold control room temperature and poor workplace ergonomic practices. The study also showed that the ergonomics deficiencies had serious health implications on control room workers as there seems to be a prevalent health hazard called computer vision syndrome (CVS). The results from the study confirmed that poor work station ergonomics impacted negatively on the wellbeing of operators in the control room. The result of the study established prevalence of CVS among control room operators in the sampled area and identified substantial work station ergonomic lapses such as lack of intermitted work breaks, display screen glare, cold working environment, poor ergonomic practices as ergonomic risk factors for CVS. The study recommends some basic ergonomic modifications in the design of oil and gas control rooms, also operators of control rooms should engage in intermitted rest breaks to reduce work-related symptoms such as eye strain, back pain, headache, and physical discomfort. Lastly, operators of control room should be trained periodically on ergonomic awareness and supervised on compliance to ergonomic work practices.

Abstract: PAA/polyaniline/MWCNT nanocomposites are synthesised. Aniline is taken as monomer whereas; MWCNT is used as additive. Prepared nanocomposites are synthesized by chemical oxidation method. XRD, FTIR, and UV-Visible, FESEM with EDS, HRTEM, DC conductivity and magnetoresistance techniques are used to characterize the prepared nanocomposite as well as raw materials. Room temperature DC conductivity, temperature dependent (presence and absence magnetic field) of above-mentioned nanocomposites is estimated by linear four-probe technique. DC conductivity are found to be xxxx S/cm (of PAA/PANI/MWCNT (0.1 wt%) nanocomposites), xxx S/cm (of PAA/PANI/MWCNT (3 wt%) nanocomposites), xxx S/cm of PAA/PANI/MWCNT (0.3 wt%) nanocomposites. Magnetoresistance of PAA/PANI/MWCNT (0.5 wt%) nanocomposite, xxx S/cm (of PAA/PANI/MWCNT (1.0 wt%) nanocomposites) at room temperature.  DC conductivity is a function of temperature. It is also studied with and without magnetic field. Conduction process of materials is followed Mott 3D-VRH model. Magnetoresistance (MR) is also estimated and shows positive MR.

Keywords: Acrylic Acid, Electrical Conductivity, Magnetoresistance, Mott 3D-VRH model, MWCNT , and Polyaniline.
