This paper analyzes the principles and the the underlying mathematical model for acoustic based shooter and launch detection systems which are crucial for border and homeland security. Acoustic based shooter detection systems use the muzzle blast and acoustic shock waves,that are formed during the flight of the bullet, and process the measurements to compute the shooter's location with high accuracy. Azimuth, elevation angle and range of the shooter are among the important parameters to be estimated.


High speed VLSI implementation of the Rijndael Encryption Algorithm
Sever, Refik; Aşkar, Murat; Department of Electrical and Electronics Engineering (2003)
This thesis study presents a high speed VLSI implementation of the Rijndael Encryption Algorithm, which is selected to be the new Advanced Encryption Standard (AES) Algorithm. Both the encryption and the decryption algorithms of Rijndael are implemented as a single ASIC. Although data size is fixed to 128 bits in the AES, our implementation supports all the data sizes of the original Rijndael Algorithm. The core is optimised for both area and speed. Using 149K gates in a 0.35-æm standard CMOS process, 132 M...
A study on symbol synchronization and channel estimation for m-ary orthogonal transmission
Karagözlü, Eren; Tanık, Yalçın; Department of Electrical and Electronics Engineering (2011)
In this thesis, two key issues regarding M-ary orthogonal signaling systems, namely channel estimation and symbol timing recovery are investigated. Kasami codes, which are also called quasi orthogonal codes, are used for transmission of the information in place of orthogonal waveforms. In order to achieve symbol synchronization, a timing recovery scheme based on the Maximum Likelihood (ML) estimation of timing offset is proposed and the effects of proposed structure over the receiver performance are examine...
Design and systemc implementation of a crypto processor for AES and DES algorithms
Egemen, Tufan; Aşkar, Murat; Department of Electrical and Electronics Engineering (2007)
This thesis study presents design and SystemC implementation of a Crypto Processor for Advanced Encryption Standard (AES), Data Encryption Standard (DES) and Triple DES (TDES) algorithms. All of the algorithms are implemented in single architecture instead of using separate architectures for each of the algorithm. There is an Instruction Set Architecture (ISA) implemented for this Crypto Processor and the encryption and decryption of algorithms can be performed by using the proper instructions in the ISA. A...
Olasilik hipotez yoǧunluǧu süzgeci kullanarak akustik sensörlerle kara araçlari takibi
Özkan, Emre; Orguner, Umut (2012-04-20)
In this paper, we explore the potential of networked microphone arrays for multiple target tracking. Tracking is accomplished by using the direction-of-arrival (DOA) estimates of multiple microphone arrays. Each microphone array obtains the DOA estimates by using the wideband extensions of the multiple signal classification (MUSIC) technique. Based on these DOA estimates, multi target tracking is done by using Probability hypothesis density (PHD) and cardinalized probability hypothesis density (CPHD) algori...
Design and implementation of low leakage MEMS microvalves
Yıldırım, Ender; Külah, Haluk; Arıkan, Mehmet Ali Sahir; Department of Mechanical Engineering (2011)
This thesis presents analysis, design, implementation, and testing of electrostatically actuated MEMS microvalves. The microvalves are specifically designed for lab-on-a-chip applications to achieve leakage ratios below 0.1 at pressure levels in the order of 101 kPa. For this purpose, two different microvalves are presented in the study. In the proposed designs, electrostatic actuation scheme is utilized to operate the microvalves in normally open and normally closed modes. Characterization of normally open...
