Investigation of rocks present under and over Hatshepsut Temple - Deir El Bahari - Upper Egypt
(2006) Pawlikowski, Maciej
Geological field investigation of rocks present under and above temple of Queen Hatshepsut in Upper Egypt were preformed. Investigation showed the place prepared for construction of temple was specially prepared. The part of rocky cliff present at the end of Deir el-Bahari valley was cut by miners. Observation of temple foundations showed the presence of thin layer containing remains of human activity represented by fragments of pottery, chacoal, dactyl stones etc. documenting the area under consideration was the building lot and construction of architectonic elements of temple was constructed step by step. Moreover observation of base of foundations showed that they are situated on the top surface of limestone layers constituting intercalations in Esna shale ore are located on Esna shale cut in from of steps. At same places mentioned layers of limestones were used as roof of underground tombs and chapels i.e. They were perforated from top down and the chambers and corridors of tombs were shafted in soft Esna shale. Rocky material removed from cut cliff was deposited as base for construction of the middle terrace of the temple. In conclusion one can say that performed investigation and reconstruction of geology conditions as well as engineering works helped understand general scheme of phases of Hatshepsut temple construction.

Sensor based cyber attack detections in critical infrastructures using deep learning algorithms
(Wydawnictwa AGH, 2019) Yilmaz, Murat; Catak, Ferhat Ozgur; Gul, Ensar
The technology that has evolved with innovations in the digital world has also caused an increase in many security problems. Day by day the methods and forms of the cyberattacks began to become complicated, and therefore their detection became more difficult. In this work we have used the datasets which have been prepared in collaboration with Raymond Borges and Oak Ridge National Laboratories. These datasets include measurements of the Industrial Control Systems related to chewing attack behavior. These measurements include synchronized measurements and data records from Snort and relays with the simulated control panel. In this study, we developed two models using this datasets. The first is the model we call the DNN Model which was build using the latest Deep Learning algorithms. The second model was created by adding the AutoEncoder structure to the DNN Model. All of the variables used when developing our models were set parametrically. A number of variables such as activation method, number of hidden layers in the model, the number of nodes in the layers, number of iterations were analyzed to create the optimum model design. When we run our model with optimum settings, we obtained better results than related studies. The learning speed of the model has 100\% accuracy rate which is also entirely satisfactory. While the training period of the dataset containing about 4 thousand different operations lasts about 90 seconds, the developed model completes the learning process at the level of milliseconds to detect new attacks. This increases the applicability of the model in real world environment.

The investigation of rocks present under and above the Hatshepsut Temple - Deir El Bahari, Upper Egypt
(2007) Pawlikowski, Maciej
Wykonano geologiczne badania terenowe skał występujących w otoczeniu świątyni królowej Hatshepsut w Górnym Egipcie. Badania wskazują, że miejsce pod budowę świątyni było przygotowywane w ten sposób, że pracami górniczymi obcięto fragment skalnego klifu znajdującego się na końcu doliny Deir el-Bahari. Obserwacje fundamentów świątyni wskazują, że część jej obiektów stawiano na płytach wapiennych występujących w obrębie łupków Esna. W cienkiej warstewce występującej między fundamentem kaplicy Hatshepsut a stropem ławicy wapiennej natrafiono na ślady aktywności budowniczych (fragmenty ceramiki, pestki daktyli, węgielki i in.). co dowodzi, że przed budową tej kaplicy teren był wykorzystywany jako plac budowy. Płyty wapieni występujące w obrębie łupków Esna były wykorzystywane zarówno jako podstawa pod fundamenty jak też jako płyty stropowe dla grobów i kaplic drążonych pod nimi w miękkich łupkach Esna. Same łupki przycinano pod fundamenty w formie stopni. Usunięty w wyniku tych prac materiał skalny wykorzystano jako 'podsypkę' pod środkowy taras świątyni. Wykonane badania geologiczne i rekonstrukcja prowadzonych w tym rejonie prac inżynierskich pozwoliły na odtworzenie ogólnego schematu i fazy budowy świątyni królowej Hatshepsut.

The vision of students regarding tomorrow's world in European engineering education
(2014) Duşe, Dan Maniu; Duşe, Carmen; Nemeş, Cătălin
Starting from Michael Rendell and his team's »Managing tomorrow's people«, this paper sets out to build a possible future of leadership in the European engineering education by taking the students' view on tomorrow's world into consideration. We can ask ourselves if European technical universities, and engineering education in particular. could exist in a Blue, Green and Orange World. How would they look like and how efficient would »corporate« universities be, assuming that the Blue World would prevail in the next 10 years. What should their development strategies be and what labor markets would absorb their graduates? What if universities would be in the Green or Orange World? What leaders should they have then? Starting from these questions we try to construct possible scenarios for a European reality.
