Opis:
W 2006 roku odkryto miejsce lokacji średniowiecznego miasta (Szamotuły). Ślady tego miasta zidentyfikowano dzięki rekonesansowi lotniczemu. To unikatowe znalezisko zostało objęte ochroną konserwatorską i dzięki temu możliwe tam jest prowadzenie tylko badań nieinwazyjnych. Te nieinwazyjne badania polegają na cyklicznym rekonesansie lotniczym oraz pozyskiwaniu nowych danych przy pomocy metod teledetekcyjnych, takich jak: metoda geomagnetyczna czy elektrooporowa. Każda z metod dostarcza informacji o innych aspektach zachowanych obiektów archeologicznych. W niniejszym tekście zaprezentowane zostały wyniki pilotażowego rozpoznania stanowiska przy pomocy metody georadarowej. Wyniki zostały skonfrontowane z interpretacją zrektyfikowanych zdjęć lotniczych. Pozytywny wynik testu pozwala planować takie rozpoznanie metodą georadarową, które da tomograficzny obraz średniowiecznego miasta.
The place where the medieval town of Szamotuły had been located was discovered in 2006. Remains of the town were identified during an archaeological aerial survey. That unique discovery has been listed on the national register of historic places and, consequently, only noninvasive investigations are allowed there. Those investigations are based on systematic aerial reconnaissance, as well as the acquisition of new data by applying remote sensing methods, such as geomagnetic or resistivity methods. Each method provides information on different aspects of buried archaeological features. First results of the pilot project of the site survey using GPR are presented herein. Results are compared with the interpretation of rectified aerial photographs. The positive output allows planning further surveys with the application of GPR to obtain a tomographic image of that medieval town.

Opis:
The main purpose of this work is to confirm the possibility of making large-scale orthophotomaps applying unmanned aerial vehicle (UAV) Trimble-UX5. A planned altitude reference of the studying territory was carried out before to the aerial surveying. The studying territory has been marked with distinctive checkpoints in the form of triangles (0.5 × 0.5 × 0.2 m). The checkpoints used to precise the accuracy of orthophotomap have been marked with similar triangles. To determine marked reference point coordinates and check-points method of GNSS in real-time kinematics (RTK) measuring has been applied. Projecting of aerial surveying has been done with the help of installed Trimble Access Aerial Imaging, having been used to run out the UX5. Aerial survey out of the Trimble UX5 UAV has been done with the help of the digital camera SONY NEX-5R from 200m and 300 m altitude. These aerial surveying data have been calculated applying special photogrammetric software Pix 4D. The orthophotomap of the surveying objects has been made with its help. To determine the precise accuracy of the got results of aerial surveying the checkpoint coordinates according to the orthophotomap have been set. The average square error has been calculated according to the set coordinates applying GNSS measurements. A-priori accuracy estimation of spatial coordinates of the studying territory using the aerial surveying data have been calculated: mx=0.11 m, my=0.15 m, mz=0.23 m in the village of Remeniv and mx=0.26 m, my=0.38 m, mz=0.43 m in the town of Vynnyky. The accuracy of determining checkpoint coordinates has been investigated using images obtained out of UAV and the average square error of the reference points. Based on comparative analysis of the got results of the accuracy estimation of the made orthophotomap it can be concluded that the value the average square error does not exceed a-priori accuracy estimation. The possibility of applying Trimble UX5 UAV for making large-scale orthophotomaps has been investigated. The aerial surveying output data using UAV can be applied for monitoring potentially dangerous for people objects, the state border controlling, checking out the plots of settlements. Thus, it is important to control the accuracy the got results. Having based on the done analysis and experimental researches it can be concluded that applying UAV gives the possibility to find data more efficiently in comparison with the land surveying methods. As the result, the Trimble UX5 UAV gives the possibility to survey built-up territories with the required accuracy for making orthophotomaps with the following scales 1: 2000, 1: 1000, 1: 500.

The settlement remains surrounding the churches at the sites of Banganarti and Selib continued to be excavated in the 2015/2016 season by a team directed by Bogdan Żurawski. The research focused primarily on the living quarters around the churches and fortifications. An ethnographic survey carried out in Banganarti and Selib, and in the nearby villages documented traditional crafts, such as pottery making, basketry, baking and cooking using traditional techniques and recipes. Conservation and construction work were undertaken simultaneously with preparations for turning the Banganarti and Selib 1 sites into tourist attractions. Skeletal remains from earlier excavation were examined by a physical anthropologist. A survey combined with aerial documentation was carried out on selected archaeological sites in the Southern Dongola Reach (Soniyat, Diffar, Hettani, Bani Israil) and in the Third Cataract Region (Kissenfarki, Fagirinfenti). Short excavations were also conducted in the temple at Soniyat.

Opis:
Wings play a vital role in the design of micro aerial vehicles (MAV), in view of aerodynamic performance, maneuverability and hovering capabilities of the vehicles. The wings are generally classified as flapping, delta, swept, and so on. In this paper, the literature is reviewed regarding the diverse techniques utilized for the design, experimentation, analysis, simulation, and modeling of different types of wings. Among these types, this paper focuses on the design of delta wings. Accordingly, we review 60 relevant research papers and provide an analysis, based on their content. First, the paper presents the chronological review of the contributions relevant for the design of different types of wings. Subsequently, we focus on various materials such as stainless steel, aluminum, carbon fiber, etc., and on parameters such as Reynolds number, angle of attack, aspect ratio, etc., which are utilized for the design of wings. The paper also provides a detailed performance study regarding the contribution to the design of delta wing. Finally, we present various research issues, which can be useful for the researchers in accomplishing further research on the design of delta wings.

Opis:
Accurately estimating the volume of earthworks is very important in mining engineering and construction. This estimation can be difficult because of the morphological condition of the stockpiles, hence, devising simpler, yet accurate methods of stockpile volume estimation is still a research problem in mining. Two non-invasive survey methods were compared in this research: the conventional ground-based and UAV-approach, for the survey of a twin-stockpile of gravel using Leica TS06 Total Station and DJI Mavic Air UAV, respectively. About 128 images of the area were acquired at 50 m flying height and 75% overlap during the flight mission. The images were processed using Agisoft Metashape Pro; a digital photogrammetric software, and the DEM obtained was used for the volume estimation. The total station data was also processed in ArcGIS to generate a TIN-model from which the volume was also estimated. The volume estimated from the TIN-model was compared with the volume estimated from the UAV-based DEM, using the volume obtained from the mill-machine as the standard. The obtained result shows that while 2750 m³ was obtained as the cumulative volume from the mill machine, the UAV approach yielded 2686.252 m³ and the ground survey approach gave 2830.713 m³. The percentage difference between the two methods compared to the actual volume is 2.94% and −2.31%, respectively. These results, and the result of the processing time analysis show that UAV approach is both accurate and time economical, which attests to the potentials of low-cost UAVs to provide robust alternative to the time-consuming and rigorous ground survey approach.
