An Analysis Tool that Detects The Code Caves in Specified Sizes for Portable Executable Files
Ugurlu, Guney; Acici, Koray (2022)Code caves represent sequential null bytes in portable executable files and are particularly used in reverse engineering. With the help of code caves, the execution flow of the program can be changed, and different codes ... -
Comparison of Different Machine Learning Approaches to Detect Femoral Neck Fractures in X-Ray Images
Acici, Koray; Sumer, Emre; Beyaz, Salih (2021)Femoral neck fractures are a serious health problem, especially in the elderly population. Misdiagnosis leads to improper treatment and adversely affects the quality of life of the patients. On the other hand, when looking ... -
Comparison of Similarity Metrics in Microarray Experiment Retrieval
Acici, Koray; Ogul, Hasan (2015)Content-based retrieval of biological experiments is a recent challenge in bioinformatics. The task is to search in a database using a query-by-example without any meta-data annotation. In this study, for retrieving relevant ... -
Inferring Microarray Relevance By Enrichment Of Chemotherapy Resistance-Based MicroRNA Sets
Acici, Koray; Ogul, Hasan (2015)Inferring relevance between microarray experiments stored in a gene expression repository is a helpful practice for biological data mining and information retrieval studies. In this study, we propose a knowledge-based ... -
Information Retrieval in Metal Music Sub Genres
Acici, Koray; Asuroglu, Tunc; Ogul, Hasan (2017)Digital music platforms use meta-data based information retrieval systems for offering songs to users for their own taste of music. According to this system, songs that are labeled by other users are compared to songs that ... -
Integrating features for accelerometer-based activity recognition
Erdas, C.Berke; Atasoy, Isil; Acici, Koray; Ogul, Hasan (2016)Activity recognition is the problem of predicting the current action of a person through the motion sensors worn on the body. The problem is usually approached as a supervised classification task where a discriminative ... -
Parkinson's Disease Monitoring from Gait Analysis via Foot-Worn Sensors
Asuroglu, Tunc; Acici, Koray; Erdas, Cagatay Berke; Toprak, Munire Kilinc; Erdem, Hamit; Ogul, Hasan (2018)Background: In Parkinson's disease (PD), neuronal loss in the substantia nigra ultimate in dopaminergic denervation of the stiratum is followed by disarraying of the movements' preciseness, automatism, and agility. Hence, ... -
A Random Forest Method to Detect Parkinson's Disease via Gait Analysis
Acici, Koray; Erdas, Cagatay Berke; Asuroglu, Tunc; Toprak, Munire Kilinc; Erdem, Hamit; Ogul, Hasan (2017)Remote care and telemonitoring have become essential component of current geriatric medicine. Intelligent use of wireless sensors is a major issue in relevant computational studies to realize these concepts in practice. ... -
Retrieving Relevant Experiments: The Case of MicroRNA Microarrays
Acici, Koray; Terzi, Yunus Kasim; Ogul, Hasan (2015)Content-based retrieval of biological experiments in large public repositories is a recent challenge in computational biology and bioinformatics. The task is, in general, to search in a database using a query-by-example ... -
A Reverse Engineering Tool that Directly Injects Shellcodes to the Code Caves in Portable Executable Files
Acici, Koray; Ugurlu, Guney (2022)Code caves are used in cybersecurity and reverse engineering and describe the space in a PE file that consists of sequential and random unused or empty bytes. Malware writers and hackers design malwares to inject shellcode ... -
Texture of Activities: Exploiting Local Binary Patterns for Accelerometer Data Analysis
Asuroglu, Tunc; Acici, Koray; Erdas, Cagatay Berke; Ogul, Hasan (2016)Recognition of activities through wearable sensors such as accelerometers is a recent challenge in pervasive and ubiquitous computing. The problem is often considered as a classification task where a set of descriptive ...
