Design and Development of a Spatial Mixed Reality Touring Guide to the Egyptian Museum
No full textMany public services and entertainment industries utilise Mixed Reality (MR) devices to develop highly immersive and interactive applications. However, recent advancements in MR processing has prompted the tourist and events industry to invest and develop commercial applications. The museum environment provides an accessible platform for MR guidance systems by taking advantage of the ergonomic freedom of spatial holographical Head-mounted Displays (HMD). The application of MR systems in museums can enhance the typical visitor experience by amalgamating historical interactive visualisations simultaneously with related physical artefacts and displays. Current approaches in MR guidance research primarily focus on visitor engagement with specific content. This paper describes the design and development of a novel museum guidance system based on the immersion and presence theory. This approach examines the influence of interactivity, spatial mobility, and perceptual awareness of individuals within MR environments. The developmental framework of a prototype MR tour guide program named MuseumEye incorporates the sociological needs, behavioural patterns, and accessibility of the user. This study aims to create an alternative tour guide to the human guide that is able to enhance the museum experience. The data gathering procedure examines the functionality of the MuseumEye application in conjunction with pre-existing pharaonic exhibits in a museum environment. This methodology includes a qualitative questionnaire sampling 102 random visitors to the Egyptian Museum in Cairo. Results of this research study indicate a high rate of positive responses to the MR tour guide system, and the functionality of AR HMD in a museum environment. This outcome reinforces the suitability of the touring system to increase visitor experience in museums, galleries and cultural heritage sites

Are Local Features All You Need for Cross-Domain Visual Place Recognition?
No full textVisual Place Recognition is a task that aims to predict the coordinates of an image (called query) based solely on visual clues. Most commonly, a retrieval approach is adopted, where the query is matched to the most similar images from a large database of geotagged photos, using learned global descriptors. Despite recent advances, recognizing the same place when the query comes from a significantly different distribution is still a major hurdle for state of the art retrieval methods. Examples are heavy illumination changes (e.g. night-time images) or substantial occlusions (e.g. transient objects) . In this work we explore whether re-ranking methods based on spatial verification can tackle these challenges, following the intuition that local descriptors are inherently more robust than global features to domain shifts. To this end, we provide a new, comprehensive benchmark on current state of the art models. We also introduce two new demanding datasets with night and occluded queries, to be matched against a citywide database. Code and datasets are available at https://github.com/gbarbarani/re-ranking-for-VPR
Simultaneous Schedule of Trains and Track Maintenance According to Stochastic Blockage Time
No full textYou will find our latest publication entitled "Simultaneous schedule of trains and track maintenance according to stochastic blockage time" with Mostafa Bababeik, Mohamad Farjad Amin, and amirhossein fani. This research has been published in the Q2 International Journal of Rail Transportation and was conducted at the University of Tehran. In this paper, using stochastic mathematical programming, we have investigated the simultaneous scheduling of trains and operations for a single-track line to minimize both the #traveltime of trains and maintenance duration. #railway #maintenance #optimization #transportation #programming</div
Open Research Infrastructure: Fundamentals and Concepts (Arabic)
No full text<p>The concept of open research infrastructure revolves around the principles of openness, accessibility, reproduction and use of research. It includes a wide range of digital tools, platforms and resources that facilitate the exchange and dissemination of research outputs, data, methodologies and software. In recent years, the importance of open science has increased significantly as the scientific community has recognized its potential to accelerate discoveries, improve the quality of research, and foster global collaboration.<br><br>In this workshop, Nabil and Mohamad are highlighting (in Arabic) the definition of Open Science and the role of Persistent Identifiers (PIDs) in building a trusted open research infrastructure.

Enhancement of waste activated sludge hydrolysate digestion efficiency via promotion of direct interspecies electron transfer
No full textAnaerobic digestion (AD) of waste activated sludge (WAS) yields low methane (CH4) because extracellular polymeric substances hinder hydrolysis and limit its biodegradability. Pretreatment methods such as alkaline or mechanical disruption can enhance solubilization; however, the resulting hydrolysate often contains recalcitrant compounds that inhibit further degradation. In this study, a combination of alkali along with ultrasonication was applied to enhance the solubilization of WAS, followed by CH4 production under AD. Pretreated results showed alkaline (pH = 12) + ultrasonication (30 min) showed 300 % higher solubilization compared to ultrasonication (60 min) alone. Batch experiments (with and without Fe3O4) were conducted, and the results showed that pretreated hydrolysate supplemented Fe3O4 showed higher CH4 yield than their control counterparts (up to 85 %). To validate the batch results of pretreated hydrolysate, a continuous operation was conducted without (Control) and with an electric voltage reactor (EVR) at different organic loading rates (OLR) up to 4 g chemical oxygen demand (COD)/L/d. The results showed that EVR enhanced the CH4 production by 28 % and COD removal by 19 % at 4 g COD/L/d compared to the control. Microbial community analysis highlighted the dominance of Syntrophomonas zehnderi (a fatty acid oxidizer) in EVR, which increased by 27 %, suggesting stronger syntrophic partnerships with methanogens. Genetic profiling further supported these findings, showing a 25 % upregulation in Adenosine triphosphatease related genes and a striking 69 % increase in pili-associated genes, both critical for direct interspecies electron transfer. These results demonstrated that the combined pretreatment (alkali + ultrasonication) offers a promising alternative for enhanced AD of WAS.
