We study the new geometric flow that was introduced in [11] that evolves a pair of map and (domain) metric in such a way that it changes appropriate initial data into branched minimal immersions. In the present paper we focus on the existence theory as well as the issue of uniqueness of solutions. We establish that a (weak) solution exists for as long as the metrics remain in a bounded region o...

This paper presents a chaotic map based cryptography technique, in the proposed technique; confusion and diffusion applied on spectral domain (on DCT(Discrete Cosine Transform) coefficients) hence the encryption can be achieved quickly without applying the large number of confusion and diffusion cycle as it is needed in spatial domain. Also the diffusion template is created by random number gen...

Introduction Echo-planar imaging (EPI) is a group of fast data acquisition methods commonly used in fMRI studies. It acquires multiple image lines in k-space after a single excitation, which leads to a very short scan time. A well-known problem with EPI is that it is more sensitive to distortions due to the used encoding scheme. Source of distortion is inhomogeneity in the static B0 field that ...

Speech coding has become one of the most essential techniques in telecommunications and in the multimedia infrastructure. Existing speech coding techniques are applicable only for stationary environment and degrade the speech quality. This paper proposes a novel speech coding technique with better speech quality through MCRA and modified MAP. Maximum A Posteriori (MAP) criterion is extensively ...

the balanced scorecard framework with a hierarchical, multilayer, and causal-effect structure can shed light on the growth path and pave the development steps, which in addition to monitoring the financial goals. it also considers and controls the other effective and driving factors. in this study, after reviewing the balanced scorecard, a model was proposed in addition to extract the strategic...

This paper addresses cell data quality problems encountered in map matching based on passive mobile positioning data. The passive positioning data is typically on cell global identifier level, i.e. data record tells that the mobile station was connected to given cell at given time. Each cell has attributes that can be used to estimate the effective area of the cell. The assumed cell area can ve...

Virtual assisted lung mapping (VAL-MAP) is a new technique for bronchoscopic lung marking developed to assist in navigational lung resection. Unlike conventional marking techniques using a single marking to identify an intrapulmonary tumor, VAL-MAP utilizes multiple dye-mediated markings, providing “geometric information” on the lung surface. The purpose of the technique is to identify a tumor ...

This paper presents a new fractionally-spaced maximum a posteriori (MAP) equalizer for data transmission over frequency-selective fading channels. The technique is applicable to any standard modulation technique. The MAP equalizer uses an expanded hypothesis trellis for the purpose of joint channel estimation and equalization. The fading channel is estimated by coupling minimum mean square erro...
