A case-based research method was chosen with the aim to provide an exemplar of practice and test the proposition that the use of simulation can improve productivity. Three alternatives were performed by considering the aspects of operator, machine, and workstation to define productivity improvement alternatives for operation optimisation. The research determines the optimum result to improve the current operation system. The experiments on simulated and real data clearly indicate that the productivity improvement in the current performance can be achieved by re-allocating the number of operators and machines effectively instead of a combination. The paper presents a novel example of the use of simulation to estimate the production line performance. The paper highlights this method by addressing this operational issue and the likelihood of the success of the strategic decision to improve productivity.

[abstFig src='/00290002/13.jpg' width='300' text='Robotic arm operation system' ] This paper reports on a study on the intelligent cooperation control system with human operators. The remote operation of a robotic arm by a human operator is considered as a simplified resilient system. In the experiments, subjects operated a robotic arm to carry out a simple task, while observing it through a monitor. The display of the monitor suddenly disappeared, and the subject continued the task only by using auditory information. By analyzing the relationship between task performances and types of auditory information through a mathematico-statistical method, it was found that not only auditory information related to the position but also the auditory information to ideate the position of the robotic arm was effective for task completion.

This presentation describes a geospatial reference framework for managing student surveyed topographic data of a university campus. This topographic data is collected annually by Geodesy and Geomatics Engineering (GGE) students at the University of New Brunswick (UNB) as part of the requirements for a UNB course. Examples of the type of features collected include: buildings, roads, sidewalks, walking paths, bike racks, parking lots and parking designation (e.g. accessibility parking). The applications and the information products built for managing this student surveyed topographic data can be viewed as a geospatial reference framework for this GGE survey camp.

AbstractAt Port Kanda, Japan, a systematic project for detection, recovery, and destruction of sea-disposed chemical munitions is ongoing. This project is unique in its size, scope, and the complexity of operations, and, therefore, provides an excellent case study. The systems used include a high efficiency magnetometer system for detection and identification of chemical munitions, a chemical agent resistant diving gear, a double-walled container for chemical munitions recovery and transport, and a DAVINCH® float detonation system. The development of the systems is described together with the testing results and operating record.The surveyed and cleaned-up area is 650 ha, and over 2,700 chemical munitions have been recovered and destroyed. The pre- and post-recovery sampling and analysis results are disclosed to the public to gain their acceptance and assure them that no contamination remains. The potential impacts to seafood from arsenic-bearing compounds were a concern and are briefly discussed.A deep sea operation system involving a remote recovery sealing-up container, and DAVINCH®, a floating detonation system on the recovery site, are proposed. The authors introduce the concept of “Critical Depth” for the munitions clean-up. This is the reasonable depth to which recovery of a potential source of contamination should be considered and beyond which it should not.

Harsh Conditions

Several mounts ago, during emergency meeting of UN Security Council, General Secretary Antonio Guterres, made a very trebling statement, that Cold war is back and it is even more dangerous than in the 60’s. This is not news for majority of scientific community. New international conflict started in 2014 when Russia annexed Crimean peninsula. New international conflict will definitely change the balance in international relations. The most vulnerable in these new conditions are the young democracies and countries that formed several decades ago due collapse of USSR and the whole communist bloc, Ukraine, Moldova, south Caucasian and Baltic states.  Imperial past left a lasting mark on economical, social and political life of newly form states. Soviet social experiments led to good number of problems for the former republics, ranging from political to territorial. Russian Federation uses these problems for her advantage. Surviving in this harsh conditions and reforming their society is the main challenge of  young European countries. Key words: Ukraine, Moldova, Russia, Putin, hybrid war, post-soviet space, international security

Mountain Catchment

The aims of this case study are to assess water quality in a small, forested mountain catchment in the Black Forest, forming part of a National Park and Natura 2000 zone. Field work was carried out in the catchment of the Seebächle torrent, a small headwater basin of the River Acher, a confluent of the Rhine, in Southern Germany between late winter and early summer of 2018. The catchment has a diverse natural setting of water bodies, including springs, torrents, and a lake, and is impacted by anthropogenic activities such as summer tourism, winter sports, two quarries, road traffic, and an isolated construction site. Physio-chemical and bacterial water samples were obtained at 10 measurement sites, including a spring, a lake (Mummelsee), a fountain, artificial and natural snow on and next to a ski run (Seibelseckle), artificial ditches and parking lots draining the ski run, and the Seebächle torrent above two granite mines. Samples were either taken directly on site or analyzed in corresponding hydrology and hospital microbiology laboratories. Water of the Seebächle is oxygen-rich, peaty, and mostly acidic, but the pH varies between 4.1 and 9.5 throughout the catchment, inclining towards acid in the fountain and below the ski run and towards alkaline in the lake. Conductivity is spatially highly variable, reaching the most elevated values below the ski run and its parking lot (149 µS/cm). A high density of bacteria including enterobacteria was detected at nearly all sites. Human pathogenic bacteria were found below and surrounding the ski run, at parking lots draining the ski run, as well as at the lowest site during the mid-spring campaign. They were also detected in the touristically highly frequented lake and in the spring feeding the lake during the end-of-spring campaign. Whilst most physico-chemical parameters followed a similar pattern and fell within good to very good EU drinking water quality status, the lake turbidity levels (19.2 NTU) by far exceeded norms after ice thawing. The most contaminated site in terms of bacteria and turbidity (5.2 NTU), ammonium nitrogen (0.18 mg/L), and total nitrogen (5.06 mg/L) was the spring feeding the Mummelsee draining the construction site of a new restaurant. These field analyses show that the water quality of a virtually uninhabited, natural headwater catchment is strongly interconnected and can degrade both by direct and indirect impacts of overtourism.

Traffic Rules

The increase of ships crossing encounter in the intersection water of bidirectional navigation Y-fairway (YF) seriously decreases the port service level. So it is necessary to study the ship traffic rules in YF intersection water to improve this phenomenon. This paper first analyzes the ship navigation characteristics in YF intersection water. Then a simulation model for ship sailing operation system of YF is built to study the influence of different traffic rules on port service level. Traffic rules separately are First Come First Serve (FCFS), Larger Ship Priority (LSP) and Ship Leaving Port Priority (SLPP). Finally, a case study is introduced to analyze the influence of each rule on port service level. The results show that traffic rules have little effect on port service level for smaller scale ports. But LSP maintains higher port service level with the increase of port scale, while SLPP reveals obvious advantage if port scale continues increasing. And the advantage of SLPP is more and more obvious with the increase of port scale.

The aim of the study was to develop a model of the readiness and reliability of an aircraft to perform an air task. The applied research method uses quantitative statistical methods and Markov processes in order to create a mathematical algorithm to exploit a selected aircraft type. The paper presents a case study of the TS-11 “Iskra” aircraft. The results show that even if the probability of being on stand-by is low, the tasks can be completed by operating the entire fleet properly.
