Abstract: Stakeholders in cross-border logistics and trade corridors have always beenconcerned about ways of improving operational efficiency. Cargo owners andcargo forwarders have been particularly concerned with long delays in theprocessing and clearing of cargo at border-posts. It is reasonably suspectedthat the delays are due to a combination of a lack of optimum systems’configurations and the inefficient human-dependent operations, which makesthe operations prone to corruption. This paper presents the findings of a study,which is being conducted to determine the sources of the inefficiencies and thensuggest possible solution based, largely, on RFID technology. The procedureand preliminary findings are presented

Abstract: Wireless transfer of electrical energy between air-cored circular coils can beachieved using contactless inductive power transfer (CIPT) system. Notwithstanding,the aim of designing CIPT systems is not always realized becauseof coil misalignments between the primary and the secondary coils. Based onthis information, the author of this paper analyses the effects of lateral andangular misalignments on the magnetic field and the magnetic force betweenfilamentary circular coils which are arbitrarily positioned in space. This investigationis achieved based on advanced and relevant models formulated inthe literature. Detailed results obtained using SCILAB application softwareis given.

Abstract: This paper analyses the impacts of lateral and angular misalignments on themutual inductance and the magnetic force between circular filaments whichare arbitrarily positioned in space. Advanced and relevant models availablein the literature are used to accomplish the aim of this paper. Using SCILABapplication software, the results obtained based on the theoretical model showthat as the coil misalignments increase the values of the mutual inductanceand the magnetic force keep decreasing and increasing with respect to certainvariable rotation angle at any point of the secondary coil. In order tofurther investigate the impact of coil separation distance and misalignmentson the amount of voltage induced in the secondary coil, a model of air-coredtransformer is constructed. The experimental results obtained show that theamount of the induced magnetic flux from the primary coil into the secondarycoil becomes weaker if the coil separation distance and coil misalignmentsincrease.As a result, a much smaller value of the mutual inductance is obtainedresulting to a much smaller induced electromotive force in the secondary coil.In conclusion, this study shows that the full benefits of contactless inductivepower transfer (CIPT) systems will not be realized if issues regarding coilseparation distance and misalignments are not tackled in the model to bedesigned for the CIPT transformer.

Keywords: Circular filaments, coil misalignments, mutual inductance,magnetic force.

Abstract: The evaluation of traffic in a system is an important measurement in manystudies. Counting the number of items in a system has applications in allprocessing operations. Electronic messages circulating in a network, clientsshopping in a supermarket and students attending programs in a school areexamples of entities entering, staying and exiting a system. We introduce aBayesian updating methodology for the gamma distribution for the analysisof stay times in a system. The methodology was first developed for areasmonitored by surveillance cameras. The number of people in the covered areawas determined and the average stay time was estimated using a gamma probabilitydistribution.We extend the application to the generic case and presenta simple updating methodology for the estimation of the model parameters.

Keywords: Traffic estimation, gamma distribution, Bayesian statistics.

Abstract: Applications of Ultrasound in examining physical health of patient are continuouslyexpanding over last few decades. Ultrasound imaging has assisteddoctors in the diagnosis of medical health of patient in obstetrics, cardiology,gynaecology, musculoskeletal, urology and others. It has proved to bevery promising and considerably advantageous over other imaging methodsbecause of its features like non-invasive nature, use of non-ionizing radiation,portability, rapidity in performance, ease and cheap availability, realtime imaging capability, high patient acceptability. Despite many advantages,it suffers from Speckle noise which results in affecting image resolutionand contrast making an adverse impact on the diagnostic capability of theimaging modality. In this paper, we attempt to remove speckle noise frommusculoskeletal ultrasound image for shoulder application using AnisotropicDiffusion and Non-Local Means (NLM) method. The quantitative analysisof the result is done using measurement indexes such as peak signal to noiseratio (PSNR), signal to noise ratio (SNR) and root mean square error (RMSE),whereas, visual inspection is carried out for qualitative analysis.

Keywords: Ultrasound Imaging, Speckle Noise, Anisotropic Diffusion,Non-Local Means, Quantitative Analysis.
