The Adaptive Multi-Level Phase Coding Method in Audio Steganography

IEEE Access, 2019
Audio steganography allows and inspires many researchers to design methods for secure communication. Based on the evaluation on the existing methods, it was found that most methods focused on one or two requirements while disregarding others, causing ...

Structural problems without structural solutions? Youth leaders' perceptions of their community

American Journal of Community Psychology, EarlyView.
Abstract As young people explore and reflect on the conditions of their neighborhoods and communities, they can forge a critical consciousness—merging their perspectives and analysis to direct both individual and collective actions. Photovoice is a methodological tool that allows participants to document their perspectives and analysis and discuss with

Navigating an STI diagnosis: The role of social support, intergenerational learning, and transformative growth among Black women

American Journal of Community Psychology, EarlyView.
Abstract Black women face a myriad of challenges that heighten their susceptibility to sexually transmitted infections (STIs), resulting in a disproportionate impact of STIs among this population. Yet, there is a lack of research that explores how women navigate these diagnoses with resilience.

Type-IV DCT, DST, and MDCT algorithms with reduced numbers of arithmetic operations

, 2009
We present algorithms for the type-IV discrete cosine transform (DCT-IV) and discrete sine transform (DST-IV), as well as for the modified discrete cosine transform (MDCT) and its inverse, that achieve a lower count of real multiplications and additions ...

Novel Ideas for Lossless Audio Coding

International Journal of Electronics and Telecommunications, 2012
Abstract Novel ideas for lossless audio coding analyzed in the paper are linked with forward predictor adaptation, and concern optimization of predictors on the basis of zero-order entropy and MMAE criterions, and context sound coding. Direct use of the former criterion is linked with exponential growth of optimization procedure, hence, a ...

Facilitators and barriers to neighborhood social integration

American Journal of Community Psychology, EarlyView.
Abstract Social isolation has reached concerning rates, particularly in the wake of the COVID‐19 pandemic. Social integration is critical to combatting social isolation and loneliness by promoting a sense of community and belonging. Yet, most existing research centers on fostering close personal relationships within family and friend networks.

Visual Feature Domain Audio Coding for Anomaly Sound Detection Application

Algorithms
Conventional audio and video codecs are designed for human perception, often discarding subtle spectral cues that are essential for machine-based analysis. To overcome this limitation, we propose a machine-oriented compression framework that reinterprets
