A new operational matrix based on Bernoulli polynomials

In this research, the Bernoulli polynomials are introduced. The properties of these polynomials are employed to construct the operational matrices of integration together with the derivative and product. These properties are then utilized to transform the differential equation to a matrix equation which corresponds to a system of algebraic equations with unknown Bernoulli coefficients. This method can be used for many problems such as differential equations, integral equations and so on. Numerical examples show the method is computationally simple and also illustrate the efficiency and accuracy of the method

Towards 'Slow' and 'Moderated' Urbanism

The city-building process in the global South is characterised by both the state and corporate-led production of “fast” cities. It is interesting to note that while many cities in the global North are moving towards alternative development regimes under the “slow city” movement, urban production in traditional societies of the global South is being enslaved to “speed.” The analysis of the changes being brought about in these cities reveals how alternative forms of development and social organisation—termed as slow cities, akin to slow food—can lead to more sustainable cities and “eurhythmia” in urban life

Biological Activities and Molecular Analysis of Novel Dithiocarbazate Complex Compoundson Glioma Cell Lines

The object of research in the exploration of new chemotherapy agents is to kill cancerous cells and not harm the healthy cells. In addition, an effective dose of these agents is essential in conducting clinical studies in the treatment of cancer. In this study, an investigation of the anticancer effects of a group of synthetic compounds on human glioma cell lines was carried out. Initially, 11 compounds were screened using cytotoxicity assays. The most active compounds were found to be derived from bis (S-methyl-I3-N-(2-acetylfuran) dithiocarbazate) (SMDB) and bis (S-benzyl-I3-N-(2-acetylfuran) dithiocarbazate) (SBD4) complexed with zinc, cadmium and platinum ions. The glioma cell lines, A172, U87MG and T98G and normal brain cell line HCN-2, were used in this study. The ICso values of the cell lines treated with the compounds were determined by using (3-4,5-dimethylthiazol-2-yl)-2-5-diphenyltetrazolium bromide (MTT) assay. Tamoxifen was used as a control as it is the current drug of choice in the treatment of brain cancer. From the cytotoxicity assays, it was found that the compounds which showed the most potential are SMDB-Cd and SMDB-Zn. The ICso values for SMDB-Cd on A172, U87MG, T98G and HCN-2 were O.65IJg/ml, O.29IJg/ml, OAlJg/ml, and 1AlJg/ml, while that for SMDB-Zn were at 3.7IJg/ml, 1.76IJg/ml, 2.71Jg/ml and 7lJg/ml, respectively. The ICso values for tamoxifen for the same cell lines were 6.7IJg/ml, 5.3IJg/ml, 6.31Jg/ml and 6IJg/ml respectively. Several methods were employed towards understanding the mechanism of action at the molecular level for SMDB-Cd and SMDB-Zn on glioma cell lines. Tunel assay displayed the typical morphological features of apoptosis cells with condensed and fragmented nuclei at 48 hours. The percentage of apoptotic cells in all treated cells with tamoxifen, SMDB-Zn and SMDB-Cd were significantly (p<O.05) increased. Reverse Transcription-Polymerase Chain Reaction (RT-PCR) was used in monitoring the gene expression level of two key genes, Epidermal Growth Factor Receptor (EGFR) and Mouse Double Minute 2 (MDM2). The expression of EGFR gene was suppressed in all three-cell lines. However, MDM2 gene was suppressed only in A172 and T98G. Therefore, the suppression of EGFR and MDM2 by the compounds was one of the pathways to apoptosis in the glioma cells.In the flow cytometry analysis, the effect of SMDB-Cd and tamoxifen on the cell cycle after 3, 6, 12 and 24 hr treatment showed glioma cells A172, U87MG and T98G were arrested in G1 phase and the SMDB-Zn arrested glioma cell lines U87MG, T98G and A172 in, G2/M, S phase and G1 phase, respectively. The SMDB-Cd and tamoxifen arrested the cell cycle by preventing replication (phase specific G1 ) whereas SMDB-Zn was not phase specific which can arrest the cell at any point in the cell cycle. Results, of caspase-8/9 activity assay of tamoxifen, SMDB-Cd and SMDB-Zn on glioma cells showed that caspase-8 activity was significantly induced but no significant activity for caspase-9 was observed. Therefore, the activation of caspase-8 may be the mechanism through which tamoxifen, SMDB-Cd and SMDB-Zn induces apoptosis. The comet assay used to study the genotoxic activity of SMDB-Cd and SMDBZn in CHO cell line showed no genotoxic activity in both compounds. In conclusion, the two compounds have the potential to be developed as chemotherapeutic agents.

A KD framework in football data analytics: a value co-creation framework for the use of knowledge discovery technologies in the football industry

Investment in sport technologies are expected to grow by 40.1% during 2016-2022 reaching approximately $3.97 billion by 2022. As well the recent changes in technology regulations by The Federation Internationale de Football Association (FIFA) since the 2018 World Cup created promising football technologies. This research questions addressing the issue of what is the value of such technologies for professional football teams? and what are the benefits of these technologies? This is achieved by developing a framework for understanding the value co-creation process from the knowledge discovery systems in the football industry. The framework aids in mapping the resources, pinpointing the outputs, identifying the competencies leading into capabilities, and finally in realisation of the value of the final outcomes in that journey. On another words, different teams have different resources that allow them to achieve certain outputs. These outputs enable the coaching team to achieve and maintain certain abilities. By changes in practice the will improve the team ability and enhance their analytical capabilities. Therefore, that will allow and aid the coaching team to gain new outcomes such as improving training strategies, transferring players, and informative match strategies. Additionally, improved understanding of the value co-creation process from the knowledge discovery systems in the football industry answering, why are some teams better able to gain value from investment in knowledge discovery technologies than other teams in the football industry. The framework has been developed in three phases in which semi-structured interviews where used in the first and second phases for developing and validating the framework respectively. The third and final phases is verifying the framework by developing a knowledge discovery maturity model as an online assessment s tool in operationalising the research findings. The main contributions of this research are the adaptation and customisation of Melville et al. (2004) to develop a value co-creation process form knowledge discovery resources. Moreover, applying Agile (APM, 2015) artefacts and techniques and tools in improving the value co-creation process between coaches and data analysts. That s aided in developing the value co-creation knowledge discovery framework in football analytics. Additionally, the development of a key performance indicators balanced scorecard and its adaptation as a in understanding the relationships between the key performance indicators (i.e. physical, psychological, technical and tactical performance indicators). Finally, the development of the knowledge discovery maturity model in football analytics which was used in understanding and pinpointing areas of strength and weakness in the utilisation of the various football resources used in football analytics (human resources, technological resources, value co-creation resources and analytical models used)

Thermoviscoplastic modelling of asymmetric effects for polymers at large strains

AbstractGlassy polymers such as polycarbonate exhibit different behaviours in different loading scenarios, such as tension and compression. To this end a flow rule is postulated within a thermodynamic consistent framework in a mixed variant formulation and decomposed into a sum of weighted stress mode related quantities. The different stress modes are chosen such that they are accessible to individual examination in the laboratory, where tension and compression are typical examples. The characterisation of the stress modes is obtained in the octahedral plane of the deviatoric stress space in terms of the Lode angle, such that stress mode dependent scalar weighting functions can be constructed. Furthermore the numerical implementation of the constitutive equations into a finite element program is briefly described. In a numerical example, the model is used to simulate the laser transmission welding process

Heterogeneous wireless networks for smart grid distribution systems: Advantages and limitations

Supporting a conventional power grid with advanced communication capabilities is a cornerstone to transferring it to a smart grid. A reliable communication infrastructure with a high throughput can lay the foundation towards the ultimate objective of a fully automated power grid with self-healing capabilities. In order to realize this objective, the communication infrastructure of a power distribution network needs to be extended to cover all substations including medium/low voltage ones. This shall enable information exchange among substations for a variety of system automation purposes with a low latency that suits time critical applications. This paper proposes the integration of two heterogeneous wireless technologies (such as WiFi and cellular 3G/4G) to provide reliable and fast communication among primary and secondary distribution substations. This integration allows the transmission of different data packets (not packet replicas) over two radio interfaces, making these interfaces act like a one data pipe. Thus, the paper investigates the applicability and effectiveness of employing heterogeneous wireless networks (HWNs) in achieving the desired reliability and timeliness requirements of future smart grids. We study the performance of HWNs in a realistic scenario under different data transfer loads and packet loss ratios. Our findings reveal that HWNs can be a viable data transfer option for smart grids. 2018 by the authors.
