Abstract:

Tariff design is the key mechanism used to allocate electricity generation and distribution costs to customers. The designing process can be very complex not only due to the regulatory policies surrounding it but also due to the need of satisfying various parties such as the electricity distributor and the different types of electricity customers. Therefore, it is the aim of this study to formulate an optimum tariff structure for Malaysia that can deal with multiple objective functions. Utilizing secondary data gathered through various energy related sources and a goal programming approach, a new optimum tariff structure has been proposed specifically focused on domestic customers and others in general. The findings show, in the case of domestic users, having only two bands of domestic customers instead of the current practice of five, may have already helped to achieve an optimum tariff structure. The findings also show that for other types of users Malaysian current tariff structure may have yet to achieve its optimum level. While these findings are subjected to few limitations, it is notable that the findings can be used to evaluate the existing tariff structure of Malaysia.

Abstract:

In this study, response surface methodology (RSM) was augmented to determine the effects of independent variables, namely extraction temperature (45-65°C), ethanol concentration (70-90%) and extraction time (80-120 min) to optimize the retained antioxidant compounds of the red pitaya peels through responses which were total phenolic content (TPC) and total flavonoid content (TFC). Regression analysis showed that more than 90% of the variation was explained by the second-order polynomial models of the different responses and the experimental values displayed that the extraction conditions had significant effect (p<0.001) on the TPC and TFC respectively. The optimized conditions were ethanol 82% for 103 min at 56°C with values of 172.01 mg/g for TPC and 7.45 mg/g for TFC respectively, which were in a good agreement with those predicted, thus indicating the suitability of the employed model in optimizing the extraction conditions of the red pitaya peels and similar natural functional product optimization.

Abstract:

Melastoma is the family of Melastomataceae species which consists of total more than 4000 species and the most common are Melastoma malalabthricum, Clidemia hirta and Melastoma decemfidum. Continues exploration from the leaves of melastoma plant has been extensively probe for its therapeutic value. Therefore, this work aimed to investigate the photo-protective ability and antioxidant potential using DPPH-free radical scavenging assay, total phenolic content and FRAP-reducing power assay. The results show all Melastoma family species have wide range of absorbance such as UVA, UVB and UVB radiation and exhibit good SPF number where Clidemia hirta leaves extract ethyl acetate recorded to have highest SPF value among others. Meanwhile, the three of antioxidant assay shows that Clidemia hirta ethyl acetate displays higher antioxidant activity against DPPH radical and contain higher phenolic and FRAP value as compared to other Melastoma species. Therefore, it can conclude that Melastoma especially from Clidemia hirta species could be one of the potential source of antioxidants as sunscreen products and also for utilization for cosmeceutical, neutraceuticals and medicinal use in the future to overcome various diseases.

Abstract:

A Bieberbach group is a crystallographic group. This group is an extension of a finite point group and a free abelian group of finite rank. In this paper, a Bieberbach group with point group 2 2 C  C of dimension three is chosen where its polycyclic presentation is shown to be consistent. The nonabelian tensor square of group is a specialization of more general of the nonabelian tensor product of group. The nonabelian tensor square of group is one of the homological functors which can reveal the properties of the groups. Also, the nonabelian tensor squares are one of the important elements on computing homological functors of groups. The main objective of this paper is to compute the nonabelian tensor square of a Bieberbach group with point group 2 2 C  C of dimension three by using the computational method for polycyclic groups. The finding showed that the nonabelian tensor square of the group is abelian and be presented in terms of its generators. The findings of this research can be used to compute the other homological functors of this group.

Abstract:

This paper focus on the CCD with RSM optimization of parameters. Design of Experiment (DoE) hardware was developed with P&O MPPT algorithm to measure Input A: Input Voltage (VIN), Input B: Input Current (IIN), Input C: Duty Cycle, Input D: Irradiance and output power. The optimization of process parameters was successfully identified from the experimental design and CCD results. The coefficient of determination of R2 is shown 99.89% which is a good fit in the model. The adequacy prevision of 89.437 indicated an adequate signal and noise was negligible. The optimization of a set of experimental parameters and observed results were VIN: 18.82 V, IIN: 0.65A, Duty Cycle: 85% and Irradiance: 883.79 W/m2. Overall, we concluded that input voltage is the most significant term influencing output power, following by input current, duty cycle and irradiance. All results were validated by experiments, simulations and theory calculation. The validation error results between predicted and experimental output power were shown that a maximum error at +3.65% and a minimum error at 0.00%, which had validated the accuracy of the prediction.

Abstract:

In the process of the study of platform joints of panel buildings, it was established that the most significant contribution to the reliability of the joint is provided by a number of parameters which have specialty randomly. The distribution of these parameters is described by a normal principle that does not have a simple numerical solution. To determine the probability of failure of the connection in the conduct of probabilistic calculations, method of linearization is used, which is based on the method of expanding the initial function in a Taylor series. The work assesses the impact of structural parameters of the horizontal platform joint of panel buildings on the reliability of the connection. The coefficients of ponderability of the investigated parameters are determined in estimating the probability of joint failure. The practical value of the obtained research results is to increase the reliability of the node of interface panel.

Abstract:

Analysis of spatial bar structures is a labor-intensive and complex task, and it must be carried out taking into account all possible limiting states in various operating conditions of structures. The aim of this paper is to give an insight into elastic-plastic analysis that enables determining the ultimate load of space trusses with large displacements. A direct method is treated in this investigation to gain insight into the computational effort required for the method. The algorithms for the direct methods are obtained by modifying the algorithms for incremental geometrically nonlinear analysis developed by one of the authors to account for yielding and plastic deformation in the bars of the truss. A Java software application has been developed based on the algorithms and the analysis of the space arch truss has been performed. The example demonstrates that direct limit analysis of space trusses with large displacements can be implemented successfully on the Java platform. The computer application is suitable as a test platform for a broad spectrum of investigations into elastic-plastic truss behavior.

Abstract:

Plasticity properties of the masonry appear to be key requirements in order to predict seismic response from masonry construction. On the grounds of the experimental research results, the system of mechanisms of local damage in masonry elements (brick, mortar and contact nodes thereof) is formulated and justified. It is revealed that the state of interaction nodes of basic masonry materials under increasing stress is not irreversible: when the stress state of the node changes, the discrete transition from one state to another becomes possible. The proposed system of mechanisms of local damage and the tools to analyze the state of masonry elements serves grounds for elaboration of a structural model of clay brick masonry as piece-wise homogeneous multimodule composite environment. Based on the results of numerical studies of behavior of the clay brick masonry structural model with the proposed destruction mechanisms as well as on the grounds of the strength criteria system, an accurate prediction of the elastic and plastic deformation phases can be made to determine the plasticity characteristics of the masonry under biaxial stresses.

Abstract:

Vital problem, occurring in the operation process of bearing timber structures, is improvement of their durability in conditions of aggressive environment. Another aspect of this problem is the increase of fire resistance of timber-steel structures. One of the possible design solutions of this problem is given in the research work. The aim of the research is study of experimental arch with support joints on glued-in steel rods. The arch was developed based on typical timber-steel arch with span length 11.8 m. Geometric shape and sizes of the arch were kept without changes, but steel elements were replaced by timber elements. Design features of the arch and calculation methods, taking into account bearing capacity of the joints on glued-in steel rods, are given in the research work. The experimental arch showed enough reliability during the test and stiffness during transportation and mounting. The arch loading was carried out in laboratory bench by using hydraulic jacks. The load increased until the arch destruction. Deflection and deformation of glued-in steel rods were measured during the test. Information about vertical deformation in the arch and stretching tensions along the length of the rods under the load were obtained in the test results. The results show that shear tensions in the joints spread along the bonding length unevenly and they have maximum value on the surface of timber elements. The arch showed perceptivity of practical using in the mild chemical-aggressive conditions and bearing structures with high requirements of fire resistance.

Abstract:

Quick-assembling single-storey houses are one of the possible design solutions if we want to get ready-made houses in short time. It is especially important in locations where new factories and plants, fields of the fossil fuels extraction are developed, various catastrophes occurred and there is a necessity to carry out recovery works. However, the spread of quick-assembling single-storey houses slows down because of design, arrangement and technological complications, which should be settled comprehensively. The aim of the research work is to provide competiveness of such houses by improving their manufacturing level, which includes design, arrangement and technological solutions, reducing price and time of getting ready-made houses. The manufacturing level is determined by labor input, time and cost parameters. The research results show that the design solution, improving manufacturing level, is the use of prefabricated flat packets of sandwich-panels, which transform into design position during the assembling process due to transformable joints. The transportation of the flat packets can be carried out if their size allows transporting them by road transport. The arrangement and technological sustainability of the construction system includes the following stages: selection of separate arrangement and technological conditions of the system; determination of groups of arrangement, technological and economic factors, which influence on sustainability of each condition of the construction system, determination of rational spheres of influence of arrangement and technological factors on cost of the transformable houses. The developed solutions can reduce cost and time of the assembling process and improve manufacturing level of single-storey houses.
