Delamination is a critical form of failure in composite laminates which is partitioned into a combination of three pure modes namely; opening, shearing and tearing (modes I, II and III respectively). Each fracture mode contributes to the total energy required for delamination growth, due to a combination of the different damage mechanisms that occur under each mode 1-2 . To formulate reliable m...

The induction of DNA double-strand breaks (DSBs) culminates in the activation of cell cycle checkpoint responses and DNA repair machinery. The mechanism of DSB detection remains unclear although many candidate sensor proteins have been identified through cytologic, biochemical and genetic studies. In light of recent advances in our understanding of the cellular response to DSBs, we have propose...

Barium osumilite (BMAS) ceramic matrix composites reinforced with SiC-Tyranno fibers are tested in a cyclic loading protocol. Broadband acoustic emission (AE) sensors are used for monitoring the occurrence of different possible damage mechanisms. Improved use of AE indices is proposed by excluding low-severity signals based on waveform parameters, rather than only threshold criteria. The applic...

Methods The records of all patients satisfying the ACR criteria for JSLE admitted to our Hospital from 1980 to May 2014 were retrospectively reviewed. Disease activity at onset was measured by SLE disease activity index (SLEDAI); organ damage was assessed at last follow-up using the SLICC/ ACR Damage Index (SDI). Using the 1999 ACR nomenclature for neuropsychiatric (NP) lupus syndromes, patient...

Vibration-based damage detection (VBDD) is one of the techniques used in Structural Health Monitoring (SHM) for detecting structural damage. VBDD provides more efficient, reliable and economical methods to improve safety reduce cost maintenance engineering. This paper investigates performance model updating (MU) method using different types algorithms detection. A finite element analysis perfor...

To address the issues of low efficiency and high damage rates during apple harvesting packing, a parameter optimization experiment was conducted on low-damage packing device for an platform based Adams 2019 software. The aim to reduce mechanical apples process. Firstly, kinematics energetics analyses process were performed, mathematical model energy established identify main factors their range...

Determination of the borehole and fracture initiation positions is the main aim of a borehole stability analysis. A wellbore trajectory optimization with the help of the mud pressure may be unreasonable since the mud pressure can only reflect the degree of difficulty for the initial damage to occur at the wellbore rather than the extent of the wellbore damage. In this work, we investigate...

The delivery of goods is an important part, where the seller's efforts in sending order package reach consumer and become a satisfaction for consumers to be able reason again. Decision-making often faced with number confusing choices, especially selection expedition services. acquisition services main point supporting business processes. purpose this study provides more criteria determining alt...

This research project focuses on the evolution of the damage mechanic properties for un-reinforced masonry panels under dynamic inplane loads. A statistical determination of the evolution of the damage mechanic requires, for a ceramic material, the development of a time varying load pattern. The pattern should pass the criteria of similarity to existing patterns, provide time for the measuremen...
