The Republic

For almost a decade since joining NATO, the armed forces did not have an information system supporting the management of their own transport system. For military logistics, the implementation and operation of an IT system supporting the work of transport and army forces was of significant importance from the point of view of improving the efficiency of the logistics system. The progressiveness of this article is manifested in the fact that in addition to the characteristics, role and tasks of the system presented in previous studies, the author additionally carried out research, evaluated the functioning and presented directions of development of the IT system code named CONVOY. The significance of the system has even increased since NATO decided to strengthen its eastern flank in 2016. Consequently, this has resulted in an increased number of convoys on the roads that must be accompanied by competent transport and troop movement in order to be there. IT system CONVOY allows this process to be speeded up by electronic reconciliation, development and issuance of road traffic permits and monitoring them in real time.

Objectives/Hypothesis. The symptom of oscillopsia in patients with bilateral vestibular loss (BVL) can be reduced as dynamic visual acuity (DVA), the reduction in visual acuity during head movement, is improved by using real-time image stabilization, delivered by augmented reality eyewear. Setting. Tertiary multidisciplinary neurotology clinic. Study Design. Prospective experimental study. Methods. Immersive virtual reality glasses used in combination with a compact digital video camera were used. A software algorithm was developed that used a center-weighted Lucas-Kanade optical flow method to stabilize video in real time. Six patients with BVL were tested for changes in DVA using the eyewear. The ability to read a Snellen chart during a 2-Hz oscillating head rotation DVA test was measured. Results. For combined scores of vertical and horizontal head rotations, the mean number of lines readable at rest was 7.86, which dropped to 2.77 with head movement (a combination of vertical and horizontal perturbations). This increased to a mean of 6.14 lines with the image stabilization software being activated. This difference was statistically significant ( P < .001). Conclusion. This is the first successful attempt to improve dynamic visual acuity in patients with bilateral vestibular loss. Recent hardware upgrades are promising in improving these results even further.

In the distributed control system, it is not easy to communicate between different operating systems due to the different control platforms. Therefore, the control system is difficult to repair and upgrade. In this study, we employ Timed Petri Net to build up architecture of the real-time control system. The client not only can monitor the current status of production line via the World Wide Web in the OEM plant but also can allow equipment supplier to perform supervision, analysis, and repair in the real-time state. The operation of the hardware platform that is no longer limited to the personal computer (PC) can also support the use of PDA(Personal Digital Assistant) , and internet browsing hardware, and web site monitoring system connected through the web page to monitor the purpose of monitoring equipment machine.

Experience Sampling Methods

Pocket Interview is an easily configurable handheld electronic data collection and diary tool. The Pocket Interview system can be used to apply experience sampling methods that allow the collection of data in real-time and in the user’s natural environment. The system client is usually run on a personal digital assistant or smartphone. It can prompt the user to make diary entries at fixed and/or random intervals and includes an option that allows this sampling to be ‘guided’ whereby inconvenient prompts are temporarily deferred until a more convenient time through the use of contextual audio information. Subjects participating in real-time studies require high levels of commitment and exhibit difficulties maintaining their motivation. This paper describes a series of studies using Pocket Interview that explore how Guiding offers to reduce the perceived burden on study participants, improve response rates and increase the quantity and quality of replies.
