Contamination of water with organic dyes is a major environmental concern as it causes serious life-threatening problems. The present research was designed to evaluate the potential three different natural inorganic clays (NICs) i.e., Pakistani bentonite clay (PB), purchased from Alfa Aesar (BT), and Turkish red mud (RM) for malachite green (MG) dye removal an aqueous solution. Various analytic...

The availability of multicore processors and programmable NICs, such as TOEs (TCP/IP Offloading Engines), provides new opportunities for designing efficient network interfaces to cope with the gap between the improvement ra...

Despite availability of multiple non-overlapping channels in the 2.4GHz and the 5GHz spectrum, most IEEE 802.11-based multi-hop ad hoc networks operate in a single channel. This substantially reduces the bandwidth available to each node due to interference between successive hops on the same path as well as between neighboring paths. Figure 1 depicts the severity of such interference. As a resu...

The performance of an OS’s networking stack can be measured by its achieved throughput, CPU utilization, latency, and per-flow fairness. To be able to drive increasing line-rates at 10Gbps and beyond, modern OS networking stacks rely on a number of important hardware and software optimizations, including but not limited to using multiple transmit and receive queues and segmentation offloading. ...

One main group of organic chemistry is related to the aromatic compounds. In the present work, we replaced the CH group of benzene by silicon and nitrogen analogues. Then, Density functional theory (DFT) calculations were carried out for six-membered heterocyclic Si-N aromatic rings. Full geometry optimizations were performed in gas-phase, and at B3LYP level using 6-311++G(d,p) and CBSB7 basis ...

The structural stabilities, geometry and electronic properties of C24 and some its heterofullerenederivatives are compared at the B3LYP/6-311-EFG**//B3LYP/6-31+G* level of theory. Vibrationalfrequency calculations show that all the systems are true minima. The calculated binding energies ofheterofullerenes show C24 as the, most stable fullerenes by 9.03eV/atom. While decreasing bindingenergy in...

After a short introduction, the observing capabilities in the near{infrared bands of the camera/spectrograph NICS designed for the TNG are discussed, along with the expected performance in term of limiting magnitudes. The second part of the paper describes some technical details of the project, such as cryogenics, mechanics, and the system which executes data acquisition and control with the re...

Negative impedance converter circuits (NICs) are important building blocks in design and manufacturing of analog and mixed mode integrated circuits. In this paper, a catalogue of single current feedback amplifier-based negative impedance converter circuits having impedance scaling properties is proposed. Various examples are presented to illustrate the versatility of proposed NIC circuits.

This article puts forth a multistream networking paradigm, referred to as soft-source-information-combining (SSIC), support wireless Internet of Things (IoT) applications with ultrareliability requirements. For SSIC networking, an dispatcher at the source dispatches duplicates packets over multiple streams, which may be established different physical networks. If packet on stream cannot decoded...
