Evaluation of two models for securing SIP for home network communications

Demir, O. | Aktas, T.

Conference Object | 2013 | International Symposium on Wireless Personal Multimedia Communications, WPMC , pp.1115 - 1115

In this work, two different SIP communication models for smart home networks are suggested to meet the security requirements needed for verifying remote user's identity (authentication) and data privacy (confidentiality) of the connection. While the first method uses HTTP Digest Authentication for user registration security and IPSec tunnel for data confidentiality, the second method uses TLS for a secure authentication and SRTP in order to provide data confidentiality during the connection. SRTP key sharing is also provided by TLS before connection is established between a user and a home network. A pilot system is developed by usi . . .ng third party SIP stack implementation to observe the performance of the two alternatives. Results of these evaluations are presented. © 2013 NICT Daha fazlası Daha az

Millimeter wave detection of landmines

Öztürk, H. | Nazli, H. | Yegin, K. | Biçak, E. | Sezgin, M. | Dag, M. | Türetken, B.

Conference Object | 2013 | Proceedings of SPIE - The International Society for Optical Engineering8709 , pp.349 - 349

Millimeter wave absorption relative to background soil can be used for detection landmines with little or no metal content. At these frequencies, soil and landmine absorb electromagnetic energy differently. Stepped frequency measurements from 20 GHz to 60 GHz were used to detect buried surrogate landmines in the soil. The targets were 3 cm and 5 cm beneath the soil surface and coherent transmission and reflection was used in the experimental setup. The measurement set-up was mounted on a handheld portable device, and this device was on a rail for accurate displacement such that the rail could move freely along the scan axis. Measure . . .ments were performed with network analyzer and scattering data in frequency domain were recorded for processing, namely for inverse Fourier Transform and background subtraction. Background subtraction was performed through a numerical filter to achieve higher contrast ratio. Although the numerical filter used was a simple routine with minimal computational burden, a specific detection method was applied to the background subtracted GPR data, which was based on correlation summation of consecutive A-scan signals in a predefined window length. © 2013 SPIE Daha fazlası Daha az

Reconfigurable Hardware-based Genome Aligner Using Quality Scores

Gok, MY | Sagiroglu, MS | Unsalan, C | Goren, S


Smith Waterman Algorithm is a widely used tool in bioinformatics to align reads from aligning to a reference in whole genome sequencing. Mapping millions of sequences read from sequencing is a computationally expensive operation. Accuracy and performance are two important aspects of this process. FPGA based solutions are widely studied. In this paper we tried to achieve a better mapping accuracy for optimum alignment using quality scores of the bases of read sequences while keeping the performance high. We are offering a new Smith Waterman processing unit and systolic array based on quality scores.

Support Vector Machine Based Activity Detection

Uslu, G | Baydere, S


Human activity monitoring enables detecting instances when people need help during daily routines. They may have forgotten taking medication or they can experience more severe situations such as falling. Detecting their activities yield their context information revealing occurrences of such cases. We designed and implemented a solution to activity detection proposing a Support Vector Machine (SVM) based method. We gathered data through accelerometer to come up with a noninvasive solution. Our method is the combination of a feature extractor and classifier. Presented activity recognition suit eliminates the need for experimenting wi . . .th multiple features to determine the best classifying features contrary to some approaches utilizing SVM. With our SVM based activity recognizer, we classified sit, stand, lie and walk actions with 100 % accuracy Daha fazlası Daha az

A phenomenological study of spatial experiences without sight and critique of visual dominance in architecture

Basvazici-Kulac, B | Ito-Alpturer, M


Architectural phenomenology suggests that the basis of perceptual integrity between the subject and a space is multi-sensorial. However, the advancement of visual representation techniques within architecture has led to predominance of the visual experience over other sensory modalities. As a consequence, the integrity of the user's multi-sensorial appreciation of space has been largely neglected which may impact on the holistic experience of the individual. The present study uses an architectural phenomenology approach to explore user experiences of architectural spaces without reference to visual input: the aim being to elucidate . . .key sensory modalities that drive a synthesis of the spatial experience in the absence of visual cues. In this way, the study aims to highlight the role of the non-visual, as a criticism against the tendency to present architecture as a predominantly visual phenomenon. A qualitative study of spatial experiences from four congenitally blind and three late blind individuals was carried out within the framework of architectural phenomenology. Thus, although all suffered total loss of sight, it was possible to assess the impact of latent visual memories within the second group. In-depth interviews with each participant explored responses to four semi-structured, open-ended questions. They were asked to describe; 1) what an architectural space means to them, 2) the place they live, 3) the most important architectural features that affect their experience either positively or negatively and 4) the most favourable and unfavourable place they had ever been. No time limit was imposed for answering the questions. The answers were audio recorded with permission. All participants judged an architectural space predominantly by its acoustic properties, with no clear difference between the congenital or late blindness subgroups. A frequently mentioned construct was the sense of spaciousness with the acoustic properties of architectural features such as materials and ceiling height identified as critical determinants. Tactile experiences, in the form of air circulation felt on the skin also helped the participants to judge spaciousness. But, it was odour that was often described as the feature that defines the identity of a place. Contrary to common beliefs, tactile experiences using the hands were mentioned least. We conclude that non-visual senses subserve a central role in the formulation of spatial experiences for the visually impaired and postulate that they may have similarly significant impact on the experiences of the visually adept. Designing the properties of different acoustical ambiances to promote a synergy of sensory experiences through, for example, the selection of materials or dimensional adjustment at intersections, voids, openings and atria rather than concentrating on visual impact alone would enrich the environmental experience significantly Daha fazlası Daha az

Analysis of the electromagnetic field scattered by a spherical breast tumour model

Unal, I. | Turetken, B. | Bulus, U. | Canbay, C.

Conference Object | 2013 | 2013 International Symposium on Electromagnetic Theory, EMTS 2013 - Proceedings , pp.574 - 577

In this paper, a closed form solution is presented for the electromagnetic field scattered due to a lossy dielectric spherical tumour with arbitrary diameter, inside a lossy dielectric breast fat tissue medium. The analytical and simulation results are successfully compared to each other. Using this analytical method, we demonstrate the importance of accounting for selection of polarization and operation frequency of antennas used in a microwave imaging system for breast cancer tumour detection. © 2013 IEICE.
