Stability and Hopf bifurcation analysis of a biotic resource enrichment on a prey predator population in fractional-order system
No full textIn this paper, we work on predator-prey Model of fractional order. The system of the model in [1] is extending in the
sense of Caputo fractional derivatives. More specifically, the study discussed the fractional predator-prey model that rely on biotic
resources existence. The idea of Caputo derivative was employed in defining the fractional ordinary differential equations. The
fractional models’ stability analysis for the models equilibrium points were also presented. Adams-type predictor-corrector (ATPC)
scheme is applied to compute an approximation to the solution of the model of fractional order. Furthermore, we investigated the
Hopf bifurcation analysis. The result of the experiment show that, for certain values, the model undergo Hopf bifurcation, and
further confirmed that the choice of an appropriate figure of the fractional α ∈ (0,1] increase the region of the stability for the
equilibrium points
Exploitation of a technique in arranging an Islamic funeral
No full textTechnologies continue to evolve and develop as practically all activities and services such as commerce,
business, and online education can be terminated. Tragically, the commemorative service track and the
handling service still run a similar cycle as more seasoned individuals have done previously. Here, the
recommended app will help customers deal with the memory service faster and easier. The term
"Islam"means identification with God and man, and complete surrender to God in contemplations,
sayings, beliefs, and activities. Longitude in Islamic culture is sufficient and seen as a typical piece of
life. Muslims consider that change begins with one country and then another, not an end. A Muslim's
corpse is referred to in Arabic as a "burial service."I-JenzCare is a stage where service providers and
customers can coordinate their needs in serving the remembrance service plan. I-JenzCare is a
unique idea on the basis that no similar application or framework has been established regarding
dealing with Islamic burial services in Malaysia yet. This research introduces new characteristics of
the traditional Islamic burial service services practiced in the Malay community. I-JenzCare uses an
innovative Analytic Hierarchy (AHP) that requires only a mid-end cell phone to keep everything
according to the best customer experience principles. To illustrate this, the framework is a useful
application for individuals who need immediate assistance in dealing with burial services in
Malaysia
BIA based predictive equations for the estimation of body composition in paediatrics using deuterium dilution as reference technique: A systematic review
No full textIntroduction: Childhood obesity remain as an urgent public heahh issue that needs to be concerned and addressed. Broelectric impedance analysis (BIM considered as an optimal method to assess body compositions. Many BIA predictive equations have been developed using reference methods foe assessing body composition in paediatric populations but as accuracy only applies to the population from which they have been derived Objective: To summarize and assess whether the developed BIA based predictive equations are able to accurately estimate body composition in paediatrics populations using deuterium dilution as the reference method. Methodology: The review protocol was based on Preferred Reporting Items for Systematic Reviews and Meta-analysis (WAWA) guidelines. Literature search was conducted in PubMed and Scopus database for observational studies developing an equation to estimate TRW and FFM using deuterium dilution as criterion among Paediatrics. The manual search was also conducted to find more related studies. Results: A total of 15 studies were included in this systematic review. The quality of included studies was assessed using the Effective Public Health Practice Project (EPHPPI. The majority of the equations developed were able to explain more than 80% of variance of body composition estimated. Out of 25 equations available, 16 of them were cross•vandated and showed a precise estimation of 16W and F f M. Conclusion: All 25 BIA equations Identified were precise and reasonably accurate for estimation of body Composition BIA appeared to be a valuable tool to accurately address the estimation of body composition only to the populations from which they have been derived. Continuous research using multi-component models as criterion and cross-validating developed predictive equations is needed to overcome present obstacles and further improve the estimation of paediatrics body composition
Failure mode and effects analysis (FMEA) of furniture production: A case study in Kelantan state, Malaysia
No full textThe primary objective of this research is to study the critical region of the local furniture manufacturing company
by using a Failure Mode and Effects Analysis (FMEA). At the same time, the study also aims to help the organization to
minimize production costs by presenting the preliminary stage of the results of the assessment. Many industries used FMEA
as a method to improve the evaluation of the reliability of a production process. The use of FMEA is to analyze the layout
characteristics of the planned production process in order to ensure that the final product meets customer requirements and
expectations. It uses probabilities of detection and occurrence added with a few severity standards to create a risk priority
number (RPN) for rating improvement action considerations. Utilized in both the manufacturing and design processes, they
notably help to reduce cost factors with the aid of determining product and process improvements early within the
development process while changes are inexpensively and relatedly easy to do. Based on the results, there were two failure
modes with a higher RPN. The assessment is deductive as it periodically moves from one source to another. Thus, it can
assist the company in improving its manufacturing process by reducing the mistakes that been made by identifying the
cause and effect of it
Physicochemical properties of peking duck skin gelatin extracted using acid pretreatment (ADS) or mixed alkaline-acid pretreatment (ALDS)
No full textDuck skin is the by-product of duck meat production, and it is a readily available source of gelatin that may serve as an
alternative to gelatin made from pigs and cows. In this study, the physicochemical properties of Peking duck skin
gelatin were assessed. Duck skin gelatin was extracted using acid pretreatment (ADS) or mixed alkaline-acid
pretreatment (ALDS). The extraction yield of ALDS (1.95%) was significantly higher than that of ADS (1.33%), and the
recovery of protein of ALDS was 46.47% compared to 43.77% for ADS. The bloom value of ADS (364.10 g) was
significantly higher than that of ALDS (205.13 g) and commercial type B bovine gelatin (BG, 224.20 g). The high
bloom value of ADS and medium bloom value of ALDS mean that they can be used in many food applications. The
hydroxyproline content of ADS (13.84 g/100 g) also was significantly higher than that of ALDS (10.25 g/100 g) and BG
(12.87 g/100 g). The pH of ADS and BG (5.31 and 4.90, respectively) did not differ significantly, whereas the pH of
ALDS was 8.34. Viscosity values of ADS and ADLS were 13.51 and 12.35 mPas, respectively, which were significantly
higher than that of BG (3.62 mPas). Overall, these results show that duck skin is a potential raw material for gelatin
production, as it has a high bloom value and is readily available in Malaysia
Quality characteristics of biodegradable film prepared from duck feet gelatin
No full textBiodegradable films containing different concentrations of duck feet gelatin (DFG) (2.0, 2.5, 3.0, and 3.5%) were
produced, and their mechanical and physicochemical properties were measured and compared to those of
biodegradable films made from commercial bovine gelatin (CBG). Gel strength of DFG (306.96 g) was significantly
higher than that of CBG (216.78 g). Elongation at break (EAB), thickness, and water vapour permeability of DFG films
significantly increased as the concentration of gelatin increased. Films with DFG concentration of 3.5% had the EAB
value 33.00, compare to CBG with EAB value 25.56%. DFG films exhibit significantly lower water solubility compared
to CBG films. Water solubility of films with DFG concentration of 3.5% is 32.37%, meanwhile for CBG is 48.74%.
Both of the gelatin films prepared from DFG and CBG were transparent, as indicated by the high L*, ranging from
94.64 to 96.01 for DFG and 95.54 to 96.06 for CBG sources. These results indicate that DFG has great potential for
future application as a source material for production of gelatin-based biodegradable films
Effect of agriculture waste materials application on Kenaf (Hibiscus cannabinus) growth and resistancy against root knot nematode disease
No full textBRIS soil fertility and the infestation of root-knot nematode is the main challenge in Kenaf (Hibiscus
cannabinus) plantation. The growth of kenaf is largely depended on the soil nutrient level and its resistancy
against the infestation by pest and disease. This study was designed to determine the best soil treatment using
agriculture waste materials for kenaf cultivation. The experiment conducted at 5 meter x 5 meter plot for each
treatment by using Complete Randomized Design (CRD) and replicated 10 times. Soil were treated with
biochar, cow dung, organic compost, and NPK fertilizer. The performance of those soil treatments were
evaluated through the performance of plant growth and its physiological responses, as well as the plant
resistancy against root-knot nematodes infestation. The results showed that kenaf grown at the field plot
treated with cow dung has the better plant growth compared to the plants grown in other treatments. The
application of cow dung was found significantly enhanced the height of the plant, chlorophyll content, stalk
diameter, length of stalk, dry weight and fiber content of kenaf plant. In addition, the plant roots at the plot
treated with cow dung is free from nematode infestation. As conclusion, cow dung is the best soil treatment
as it is significantly produce the best result in plant growth performance, produce more fiber and free from
root-knot nematode infestation
Metaheuristic based ids using multi-objective wrapper feature selection and neural network classification
No full textDue to the significant ongoing expansion of computer networks in our lives nowadays, the demand for network
security and protection from cyber-attacks has never been more imperative to either clients or businesses alike, which
signifies the key role of cyber intrusion detection systems in network security. This article proposes a cyber-intrusion
detecting system classification with MLP trained by a hybrid metaheuristic algorithm and feature selection based on
multi-objective wrapper method. The classifier, named as HADMLP is trained using a hybridization of the artificial
bee colony along with the dragonfly algorithm. A multi-objective artificial bee colony model which is wrapper-based
is used for selection of feature. Hence, collective name of the proposed technique referred as MO-HADMLP. For
performance evaluation, the proposed method was assessed using ISCX 2012 and KDD CUP 99 datasets. The results
of our experiments indicate a significant enhancement to the efficacy of network intrusion detection when compared
to other approaches
Leadership and humour at work: Using interactional sociolinguistics to explore the role of gender
No full textThis chapter explores language and gender in the professional domain with a focus on leadership
discourse. Leadership is a particularly relevant topic for language and gender research as the notion of
leadership is gender biased, and globally prevailing gender stereotypes and expectations have real-life
implications for women and men taking up leadership roles or aspiring to do so. In our analysis of
leadership discourse and gender, we focus on humour, which is one of the discursive strategies
frequently used by leaders to achieve their various objectives. Using interactional sociolinguistics to
analyse instances of naturally occurring workplace interactions from different workplaces in New
Zealand, Malaysia, and the UK, this chapter explores how humour is used by those in leadership
positions, and critically asks whether gender is relevant. We discuss some of the advantages of using
interactional sociolinguistics as an approach, and illustrate that in spite of general stereotypes, women
and men in leadership positions frequently use humour to achieve similar aims, and differences in the
type and frequency of humour reflect and respond to a range of contextual factors. Gender was (made)
relevant primarily in those instances where humour was used to make fun of and send up gendered
stereotypes. © 2021 selection and editorial matter, Jo Angouri and Judith Baxter
