Depositional Stages Of The Eğribucak Inner Basin (Terrestrial To Marine Evaporite And Carbonate) From The Sivas Basin (Central Anatolia, Turkey), Özgen Kangal, Nazi̇re Erdem, Baki̇ Erdoğan Varol Jan 2017

Depositional Stages Of The Eğribucak Inner Basin (Terrestrial To Marine Evaporite And Carbonate) From The Sivas Basin (Central Anatolia, Turkey), Özgen Kangal, Nazi̇re Erdem, Baki̇ Erdoğan Varol

Turkish Journal of Earth Sciences

The Sivas Cenozoic Basin and coeval Central Anatolian basins such as Çankırı and Tuz Gölü are characterized by both marine and terrestrial sediments ranging in age from the Eocene to early Miocene. The evaporite regime here generally appeared during the late stage of Eocene transgression and persisted through the Oligocene time. However, marine-induced Oligocene evaporites are less known because of less paleontological evidence and regional tectonics and salt diapirism that mostly caused the destruction of their original stratigraphic positions. The Eğribucak area studied here, located about 25 km southeast of Sivas, provides a well-stratified key section to shed light on …


The Neotectonics Of Southeast Turkey, Northern Syria, And Iraq: The Internal Structure Of The Southeast Anatolian Wedge And Its Relationship With Recent Earthquakes, Gürol Seyi̇toğlu, Korhan Esat, Bülent Kaypak Jan 2017

The Neotectonics Of Southeast Turkey, Northern Syria, And Iraq: The Internal Structure Of The Southeast Anatolian Wedge And Its Relationship With Recent Earthquakes, Gürol Seyi̇toğlu, Korhan Esat, Bülent Kaypak

Turkish Journal of Earth Sciences

In southeastern Turkey, northern Syria, and Iraq, the Southeast Anatolian Wedge (SEAW) is recognized as lying between the high altitude Bitlis-Zagros Suture Zone and the Sincar Mountains on the Mesopotamian plain. This wedge narrows towards the south and contains several thrust and blind thrust zones merging with the basal thrust zone. These zones are determined mainly by locations of fault-propagation folding that generally limit the Plio-Quaternary/Quaternary plains in the region. The positions of these active thrust/blind thrust zones and their relationships to the right and left lateral faults may be used to explain the seismic activity of the region.


Assessment Of Mental Workload: A Comparison Of Machine Learning Methods And Subjective Assessment Techniques, Karim Moustafa, Saturnino Luz, Luca Longo Jan 2017

Assessment Of Mental Workload: A Comparison Of Machine Learning Methods And Subjective Assessment Techniques, Karim Moustafa, Saturnino Luz, Luca Longo

Articles

Mental workload (MWL) measurement is a complex multidisciplinary research field. In the last 50 years of research endeavour, MWL measurement has mainly produced theory-driven models. Some of the reasons for justifying this trend includes the omnipresent uncertainty about how to define the construct of MWL and the limited use of datadriven research methodologies. This work presents novel research focused on the investigation of the capability of a selection of supervised Machine Learning (ML) classification techniques to produce data-driven computational models of MWL for the prediction of objective performance. These are then compared to two state-of-the-art subjective techniques for the assessment …


Subjective Usability, Mental Workload Assessments And Their Impact On Objective Human Performance, Luca Longo Jan 2017

Subjective Usability, Mental Workload Assessments And Their Impact On Objective Human Performance, Luca Longo

Articles

Self-reporting procedures and inspection methods have been largely employed in the fields of interaction and web-design for assessing the usability of interfaces. However, there seems to be a propensity to ignore features related to end-users or the context of application during the usability assessment procedure. This research proposes the adoption of the construct of mental workload as an additional aid to inform interaction and web-design. A user-study has been performed in the context of human-web interaction. The main objective was to explore the relationship between the perception of usability of the interfaces of three popular web-sites and the mental workload …


A Software Development Process For Freshman Undergraduate Students, Catherine Higgins, Fredrick Mtenzi, Ciaran O'Leary, Orla Hanratty, Claire Mcavinia Jan 2017

A Software Development Process For Freshman Undergraduate Students, Catherine Higgins, Fredrick Mtenzi, Ciaran O'Leary, Orla Hanratty, Claire Mcavinia

Articles

This conceptual paper presents work which is part of an ongoing research project into the design of a software development process aimed at freshman, undergraduate computing students. The process of how to plan and develop a solution is a topic that is addressed very lightly in many freshman, undergraduate courses which can leave novices open to developing habit-forming, maladaptive cognitive practices. The conceptual software development process described in this paper has a learning process at its core which centres on declarative knowledge (in the form of threshold concepts) and procedural knowledge (in the form of computational thinking skills) scaffolding freshman …

Petrogenesis Of Plio-Quaternary Basanites In The Gandom Beryan Area, Kerman,Iran: Geochemical Evidence For The Low-Degree Partial Melting Of Enriched Mantle, Seyed Javad Yousefi, Abbas Moradian, Hamid Ahmadipour

Turkish Journal of Earth Sciences

In the Gandom Beryan area, basanitic lava flows erupted from fractures in the Nayband fault zone and formed an area of about 300 km2 of basanitic rocks in the western part of the Lut Block. Olivine and clinopyroxene are the major phenocrysts in a microlitic groundmass for these basanitic rocks. The geochemical data show that Gandom Beryan rocks are basanite in composition and belong to intercontinental rifts related to alkali basanites. These rocks have low Fe/Mg ratios (Fe2O3t/MgO = 1.07-1.43) with low silica content (SiO2 = 44.89-48.26 wt.%) and are high-Ti basanites. The investigated rocks are characterized by a significant …


Estimation Of The Crustal Structure In Central Anatolia (Turkey) Using Receiver Functions, Begüm Çivgin, Bülent Kaypak Jan 2017

Estimation Of The Crustal Structure In Central Anatolia (Turkey) Using Receiver Functions, Begüm Çivgin, Bülent Kaypak

Turkish Journal of Earth Sciences

The receiver function analysis method was used to determine the crustal structure in Central Anatolia, Turkey, by using teleseismic earthquake records. The method is based on the conversion of incident P waves into S waves reaching an interface in the crust or upper mantle and arrival of the converted wave to the station just after the direct P waves. A temporary seismic network, the Ankara Earthquake Monitoring Network (AnkNET), consisting of six broadband seismograph stations, has been deployed in order to monitor the seismicity in Ankara and its surroundings during the period of 2007?2010. In this study, the crustal structures …


A Conceptual Framework For A Software Development Process Based On Computational Thinking, Catherine Higgins, Ciaran O'Leary, Orla Hanratty, Fredrick Mtenzi Jan 2017

A Conceptual Framework For A Software Development Process Based On Computational Thinking, Catherine Higgins, Ciaran O'Leary, Orla Hanratty, Fredrick Mtenzi

Articles

A software development process is a mechanism for problem solving to help software developers plan, design and structure the development of software to solve a problem. Without a process to guide the structured evolution of a solution, it is extremely likely that at least some aspect of the resulting software will be omitted or incorrectly implemented. Even though the importance of utilising a software process for solving problems is accepted in the business and academic communities, it is a topic that is addressed very lightly (if at all) in most freshman undergraduate computing courses with most courses focussing on programming …

Evaluation Of Hydrogeochemical And Isotopic Properties Of The Geothermal Waters In The East Of Mount Sabalan, Nw Iran, Rahim Masoumi, Ali Asghar Calagari, Kamal Siahcheshm, Soheil Porkhial

Turkish Journal of Earth Sciences

The Mount Sabalan district is regarded as the best place to investigate geothermal activities in northwest Iran. Since the last episode of volcanic activity in the Plio-Quaternary time, hot springs and surficial steams as conspicuous manifestation of geothermal activities have appeared around the slopes of Mount Sabalan. The hot fluids circulating in this geothermal field contains anions chiefly of HCO3- and Cl-; however, SO42- content in some water samples is relatively high, imparting sulfate characteristics to such fluids. Geothermometric studies provided compelling evidence for estimation of the reservoir temperature (~150 °C) in the study areas. Thus, in this respect, the …

Feather-Like Hornblende Aggregates In The Phyllites From The Southern Sanandaj-Sirjan Zone, Iran; Their Origin And Mode Of Formation, Hossein Fatehi, Hamid Ahmadipour, Nakashima Kuzuo, Hesamaddin Moeinzadeh

Turkish Journal of Earth Sciences

Several outcrops of spectacular feather-like hornblende aggregates occur in the phyllites of the Gol-e-Gohar complex (southeast of Iran) and form special Garbenschiefer rock types. The Gol-e-Gohar complex, as a part of the southern Sanandaj-Sirjan metamorphic zone, contains a succession of metabasites, phyllites, and slates intruded by dioritic intrusions. There are two types of hornblendes in the phyllites; the first one is concentrated around the fractures and the second one is randomly distributed in the rocks and forms radial feather-like hornblende aggregates. Petrographical and chemical characteristics of these two shapes of hornblendes are the same, except the latter is developed parallel …


Dynamic Behavior Analysis Of Android Applications For Malware Detection, Latika Singh, Markus Hofmann Jan 2017

Dynamic Behavior Analysis Of Android Applications For Malware Detection, Latika Singh, Markus Hofmann

Conference papers

Android is most popular operating system for smartphones and small devices with 86.6% market share (Chau 2016). Its open source nature makes it more prone to attacks creating a need for malware analysis. Main approaches for detecting malware intents of mobile applications are based on either static analysis or dynamic analysis. In static analysis, apps are inspected for suspicious patterns of code to identify malicious segments. However, several obfuscation techniques are available to provide a guard against such analysis. The dynamic analysis on the other hand is a behavior-based detection method that involves investigating the run-time behavior of the suspicious …
