Cell-Free (CF) Massive MIMO is an alternative topology for Massive MIMO networks, where a large number of single-antenna access points (APs) are distributed over the coverage area. There are no cells but all users are jointly served by the APs using network MIMO methods. In prior work, it has been claimed that CF Massive MIMO inherits the basic properties of cellular Massive MIMO, namely channe...

Waree Tiyaboonchai and Garnpimol C. Ritthidej Development of indomethacin sustained release microcapsules using chitosan-carboxymethylcellulose complex coacervation Songklanakarin J. Sci. Technol., 2003, 25(2) : 245-254 Indomethacin sustained release microcapsules were prepared by complex coacervation of chitosan (CS) and carboxymethylcellulose (CMC) and then were hardened with glutaraldehyde (...

Near-duplicate detection is not only an important pre and post processing task in Information Retrieval but also an effective spam-detection technique. Among different approaches to near-replica detection methods based on document signatures are particularly attractive due to their scalability to massive document collections and their ability to handle high throughput rates. Their weakness lies...

Modeling fuel behavior requires an accurate description of the cladding stress response for both operational and safety considerations. The transient creep response of Zirconium alloys is commonly modeled using a strain hardening rule which is known to hold in cases with monotonously increasing stresses. However, the strain hardening rule is experimentally known to fail in scenarios such as loa...

Scientists publishing a new study in the journal JCI Insight have concluded that high-potassium foods such as avocados and bananas protect the arteries against hardening or calcification. Researchers at the University of Alabama at Birmingham found that increased potassium consumption protects against atherosclerosis, vascular calcification and aortic stiffness, or the hardening of the heart's ...

In this paper, several control techniques for induction metal treating are examined to assess their performances using resonant series inverter. In fact, many types of steel are treated with heat to increase toughness and resistance to wear. Induction heating seems to be appropriate and provides several advantages in comparison with conventional techniques. In this paper, these techniques are e...

Frequent exposure of terrestrial insects to temperature variation has led to the evolution of protective biochemical and physiological mechanisms, such as the heat shock response, which markedly increases the tolerance to heat stress. Insight into such mechanisms has, so far, mainly relied on selective studies of specific compounds or characteristics or studies at the genomic or proteomic level...

Microstructural and mechanical properties of precipitation-hardened maraging steel could be stated on a basis of magnetic properties of such a material. A correlation between mechanical and magnetic properties of the maraging steel is treated from the view of non-destructive testing during and after heat treatment as well as during use under unfavourable conditions at elevated operating tempera...

A single crystal plasticity theory for insertion into finite element simulation is formulated using sequential laminates to model subgrain dislocation structures. It is known that local models do not adequately account for latent hardening, as latent hardening is not only a material property, but a nonlocal property (e.g. grain size and shape). The addition of the nonlocal energy from the forma...
