Sound insulation in office buildings

open access: yes, 1964
Sound insulation between occupancies in office buildings forms the subject of this Digest. Some general cautionary remarks were made in a previous discussion of noise transmission in buildings (CBD 10); it is proposed here to develop office problems in ...

From Physiology to Bioheat Simulation: A Data‐Driven Framework for Core Temperature Initialization

open access: yesHeat Transfer, EarlyView.
ABSTRACT Accurate initialization of core body temperature is a critical yet often overlooked component of bioheat transfer models, particularly when such models are applied to heterogeneous populations and real‐world environmental conditions. Conventional bioheat simulations typically rely on fixed or idealized core body temperature values derived from

Noise Reduction Performance of Metamaterials Sound Insulation Plate

open access: yes
AbstractIn order to reduce the adverse effects of noise generated by urban vehicles on residents, a super-structured phononic crystals sound isolation plate is designed to enhance the low-frequency noise reduction capability of the plate by utilizing the special acoustic properties of the super-structure.

Measurement uncertainty of facade sound insulation: A comparison between ANOVA and RRT uncertainty evaluations [PDF]

open access: yes, 2017
In recent years the attention given to the measurements in the low frequency range has considerably increased, as well as their uncertainty evaluation; nevertheless, the uncertainty of field measurements, in particular façade sound insulation, has not ...

Neuroanatomical and functional correlates in borderline personality disorder: A narrative review

open access: yesIbrain, Volume 11, Issue 1, Page 19-31, Spring 2025.
Borderline personality disorder (BPD) is considered a dysfunctional, stable, and pervasive alteration in personality functioning with the inability to adapt to the environment, mental rigidity, and ego‐syntonic, and like all personality disorders is a consistent pattern of inner experience and behavior that deviates markedly from the expectations of ...

Nonlocal active sound control for composite regions

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
In the active sound control problem, additional sound sources, known as control sources, are implemented at the perimeter of a protected domain. The control sources can generate secondary sound inside the shielded domain, which attenuates incoming noise. This leads to an inverse source problem.

Digital surveillance of animals and nature recovery

open access: yesPeople and Nature, EarlyView.
Abstract Digital surveillance technologies (DSTs) are widely applied in nature recovery for their potential to generate novel data on species and ecosystems through digital tracking, automation (e.g. from hazardous locations) and from newly recruited citizen scientists.

Assessing Ageing Condition of Mineral Oil-Paper Insulation by Polarization/Depolarization Current

open access: yes, 2011
Accurately assessing the ageing status of oil-paper insulation in transformer is essential and important. Polarization and Depolarization Current (PDC) technique is effective in assessing the condition of oil-paper insulation system.
