Abstract: The aim of this research is to determine the effect of
Oxalic acid on rice husk. Rice husk was collected from Osun State, Nigeria. Two
methods of rice husk namely: Raw rice husk (RRH) and Leached rice husk (LRH)
were subjected to thermal treatment at 7000C by varying the combustion time of
1-6h to determine the effect of time on the type of silica produced. The
treated and untreated rice husks ash was then analysed by X-Ray Diffraction
(XRD) and Scanning Electron Microscope (SEM). Favourable results were obtained
from XRD patterns at 3h indicated that oxalic acid treated rice husk ash (LRHA)
produced amorphous silica of good quality. However, specific surface area of
the particle analysis at 3h, indicated the highest amount of 16.82mm2/g
and also the SEM presented appropriated morphological characteristics of the
best silica.

Abstract: Permanent magnet synchronous motors (PMSM) generate
high-frequency electromagnetic vibration and noise when powered by inverters, and the cause is high-frequency electromagnetic exciting force
(EMEF). In this paper, the frequencies and orders of EMEF are analyzed. The
expression of EMEF acted on the stator inner surface is derived and the
frequencies and orders of main components of vibration are listed. The
high-frequency vibration experiments are conducted on a surface mounted 8-pole
and 12-slot PMSM. The high-frequency vibrations near switch frequency and its
multiples are main components of vibrations of motors when powered by
inverters, and experiments are conducted to study the influence of switch
frequency on the vibration acceleration. The impacts of periodic frequency PWM
and random frequency PWM on the vibration acceleration and peak value of its
frequency spectrum are studied by experiments.

Abstract: In order to improve the performance of fertigation
equipment, a fertigation control system based on ARM and μC/OS-II is developed.
Serial screen is adopted to improve the performance of human-machine
interaction, and to decrease the load of MCU. Several tasks related to the
control system and fertigation process are designed based on the schedule of
μC/OS-II. Furthermore, a self-adaptive control algorithm combined the single
neuron with PID is proposed. The testing results of EC and PH control
demonstrate that this method is effective to the fertigation control system.

Abstract: With the development of ICS, PLC and SCADA systems are
interconnected with Ethernet and directly connected to internet, which greatly
improve the efficiency of data sharing and introduced in security threats at
the same time. Once crack fault occurrence of critical infrastructure will
result in casualties and great economic loss. Peach Fuzzer is an advanced and
extensible fuzzing platform and is restricted to those with TCP/UDP-based
protocols on Windows Platform, the PN-DCP would not be supported without publisher to send PDU correctly. So
it is urgent to develop an additional publisher for PN-DCP. In this paper, we
propose a novel Peach improvement on Profinet-DCP for industrial control system
vulnerability detection. We analyze the importance of vulnerability detecting
for PN-DCP with Peach Fuzzer. Then, introducing the Peach Framework, the
hierarchy of Profinet-DCP and the PitFile of Profinet-DCP. We also evaluate our
approach through experiments, the results can fully satisfy the requirement of
vulnerability detecting of PN-DCP on Peach platform.

Abstract: A total of 126 bacterial strains were isolated from water
samples collected from Ruvu River in Tanzania. Seventy strains were identified
by morphological, biochemical and 16s rRNA gene sequence analysis. The strains
were found to belong to Acinetobacter, Pseudomonas, Vibrio, Aeromonas or
Bacillus spp. Coagulant protein was purified from Parkinsonia aculeata seed by
ion exchange chromatography. Antibacterial effect of the purified P. aculeata
coagulant protein (PAP) and Citrus fruit juice (CF) was tested on four
bacterial strains that belonged to different genera. Bacterial cell
flocculation analyses showed that, PAP and CF aggregate both Gram-positive and
Gram-negative bacteria. Growth studies of bacterial strains incubated with PAP
and CF revealed that, inhibitory dosages of PAP ranged from 0.38 mg/L to 0.88
mg/L and growth inhibition occurred within two to four hours. The PACE and PAP
showed high coagulation activities that were similar to those observed for
chemical coagulant (alum) with turbidity removal efficiencies ranging from 93
to 98%. A simplified method used for purification of proteins together with
high antimicrobial and water coagulation activity make proteins suitable for
supplementing chemical coagulants in drinking water treatment. Also, CF is
suitable for post disinfection of water treated with proteins prior drinking in
poor communities.

Abstract: This paper presents a fault reconstruction scheme based
on sliding mode observers for sensor and actuator faults detection and
isolation for a class of uncertain nonlinear systems. A coordinate
transformation is first designed for the output equation of the system followed
by a first-order low-pass filter in order to convert the sensor faults into
equivalent actuator faults. The original system then is transformed into three
subsystems through linear transformation.

Abstract: The stability of two stratified Rivlin-Ericksen
elastico-viscous superposed fluid permitted with suspended particles (fine
dust) in porous medium has been considered. By applying normal mode analysis
method, the dispersion relation has been derived and solved analytically. For
case of exponential varying stratifications, it has been found that the system
is stable for stable stratifications and unstable for unstable stratifications
under certain conditions which are in contrast to the Newtonian fluid where the
system is always stable for stable stratifications.
