    The transportation of cargo inside shipping containers is a risky operation that requires constant monitoring activities and real-time operational actions. Yet, the detection of the real dynamics of the container and the surrounding infrastructure and extraction of true subsequent critical events is still an unresolved issue among engineers. In this paper, we analyze the new physical impact detection method, namely the Impact Detection Methodology (IDM), to detect the most obvious and force-dependent impacts from acceleration data, using the IoT sensor in an experimental environment using the heavy machinery of a seaport. By variating the threshold level, we have observed the changes in the number of impacts detected within three separate case studies. Results suggest that the optimal parameters tend to provide an adequate number of events, yet even the slightest change in the threshold level can increase or decrease the number of detected impacts in a non-linear fashion, making the detection harder, due to unforeseen external impacts on the dataset, the filtering of which is still the main priority of our future research.Web of Science109art. no. 125

    Exploration and implementation of Seaport Manatee to relieve the supply chain congestion at California ports

    For the global economy to thrive, a stable supply chain network is imperative to provide control of the seamless flow of goods. What is detrimental to supply chain performance due to inconsistency can be costly and consequently cause out-of-stock items, deficient use of container storage capacity and faulty logistics planning. This feasibility study examined leadership decisions in the face of supply chain turbulence. The analysis introduces the congestion free SeaPort Manatee in Palmetto, Florida. It establishes how this seaport could offer an alternative sea trade path to alleviate the supply chain strain since the U.S. will most likely continue to experience an increase in global trade instability. As the closest U.S. port to the Panama Canal, the study, in part, explores the significance of the canal as a primary conduit that allows Panamax and Neo-Panamax vessels expeditious transit from the West Coast to the Gulf Coast. Together with the new locks, the canal can handle ships with an overall length of 1200 feet, 160 feet wide (beam) and a draft of 40 feet. Consequently, not all vessels can travel through the Panama Canal regardless of its newly expanded locks (Rosenberg, 2019). The study also presents data to show how some cargo vessels sailing into Sea Port Manatee have a deep draft, which results in them being restricted by tidal ocean conditions. The draft is the minimum amount of water required to float the boat without it touching the bottom, allowing container vessels to successfully transport up to 15,000 (TEU) cargo containers through the canal. Catastrophic events such as natural disasters, a volatile political climate, and a health pandemic directly impact a company\u27s business strategy. This study addresses the challenge for leadership to make decisions to relieve the congestion at U.S. West Coast ports. By engaging in conversations with vessel shipping lines, shipping lines could create new sea trade routes in exchange for inefficient routes between Asia and the U.S. West Coast. This study introduced how sea-level rise will significantly influence port expansion at Sea Port Manatee and how vessels entering and exiting the port must do so under specific conditions

Average free ion concentrations inducing 50% abnormal development( EC50feew) ere determineda s 0.23 nM CU2+8, 8.0 rim Cd2+,1 28 nM Zn2+a nd 3 62 nM Pb 2+ . However, the response to some binary metal combinations indicated enhanced (synergy) toxicity at concentrations relevant for estuarine waters (e. g. EC5of'. for Cu2+i n the presenceo f C(ý: +, Zn2+a nd Pb2 +w as 0.004,0.02 and 0.04 nM, respectively). A comparison of voltarnmetric instrumentation (voltammetric in situ profiling (VIP) system versus Hanging Mercury Drop Electrode with potentiostat) highlighted the advantage of high resolution measurements (ca. 20-60 min intervals) for environmental studies and the minimisation of artefacts associated with discrete sampling methodologies. Field-based studies were carried out in two contrasting estuaries in SW England, one heavily impacted with metal contaminants (Fal Estuary) and another subject to greater variety of anthropogenic influences (Tamar Estuary). High resolution in situ trace metal speciationm easurementsc, arried out over tidal cycles, identified important information on the temporal and spatial distributions of biologically relevant dynamic (<4 nm) metal species of Cd, Pb and Cu. Variation in embryo-larval responses to discrete samples from these estuaries, effectively paralleled the metal speciation measurements showing enhanced toxicity when the marine water influence was at its lowest. In both systems, the results indicated that the combined effect of the metals studied was likely to have provided a significant contribution to the bioassay response. However, the difficulty in de-coupling the speciation measurements with biological responses was evident and supports the need for more comprehensive campaigns to study the impact of contaminants on ecosystem functioning. Bioassay and metal speciation analysis techniques were complementary, exhibiting high sensitivity and rapid responses, and would be considered effective screening tools for waters subject to intermittent inputs of metal contaminants and areas with recognised pressures. The integrated approach has extended our knowledge of trace metal speciation in estuarine environments and their effects on the developing embryos of the Pacific oyster. This approach has the potential for wider application

    Use case of quay crane container handling operations monitoring using ICT to detect abnormalities in operator actions

    This paper presents the initial research findings from the Klaipeda port monitoring action related to Blue economy development initiative in the Baltic Sea. Use case study demonstrates the possibility to address the problem of information system deployment in harsh industrial environment to gather valuable statistical knowledge. Custom made monitoring and data transmission units were developed to utilize the best practice of engineering to solve real problems of Klaipeda Port. Several key operations and parameters were monitored during the research, including containers spreader movements, physical characteristics of the cables, metal constructions. Initial results suggested that crane operators’ involvement in the control of the cargo movement produced incorrect control patterns (joystick movements) that delayed port operations. Each control movement of the joystick needs to have a direct real-time feedback from the spreader (actual movement of the cargo). Feedback control functiona lity will allow adjusting the spreader movement according to the operator and will decrease the cargo transportation time during constant breaks

    ABSTRACT Kampung houses are houses in kampung area of the city. Kampung House oftenly transformed into others use as urban dynamics. One of the transfomation is related to the commercial activities addition by the house owner. It make house with full private space become into mixused house with more public spaces or completely changed into full public commercial building. This study investigate the spatial transformation pattern of the kampung houses due to their commercial activities addition. Site observations, interviews and questionnaires were performed to study the spatial transformation. This study found that in kampung houses, the spatial transformation pattern was depend on type of commercial activities and owner perceptions, and there are several steps of the spatial transformation related the commercial activity addition. Keywords: spatial transformation pattern; commercial activity; owner perception, kampung house; adaptabilit
