Quantity Vs. Quality in Information
Two coordinated aspects of Quantity and Quality existing under the
influence of anticipated sources of information have passed several
challenges to evaluate perfect information management techniques.
Paper discusses a few issues covering the implication of Information

Relaxed Local Correctability from Local Testing
We cement the intuitive connection between relaxed local correctability and
local testing by presenting a concrete framework for building a relaxed locally
correctable code from any family of linear locally testable codes with
sufficiently high rate. When instantiated using the locally testable codes of
Dinur et al. (STOC 2022), this framework yields the first asymptotically good
relaxed locally correctable and decodable codes with polylogarithmic query
complexity, which finally closes the superpolynomial gap between query lower
and upper bounds. Our construction combines high-rate locally testable codes of
various sizes to produce a code that is locally testable at every scale: we can
gradually "zoom in" to any desired codeword index, and a local tester at each
step certifies that the next, smaller restriction of the input has low error.
Our codes asymptotically inherit the rate and distance of any locally
testable code used in the final step of the construction. Therefore, our
technique also yields nonexplicit relaxed locally correctable codes with
polylogarithmic query complexity that have rate and distance approaching the
Gilbert-Varshamov bound.Comment: 18 page
Impact of Internet Marketing on Marketing Performance in India SMEs
As the economic sector transitions to digitalization, Indians now have access to the best goods and services from the best companies, even in the most remote regions of their nation. E-marketing is booming in India, a nation that is both highly populated and home to millions of people who utilise social media and mobile devices. Internet-based marketing is essential for everyone who wants to grow their company and advertise their goods and services globally because it has no territorial restrictions. To scatter the needs paper aims at analysing the connections between e-Marketing tools and marketing performance among SMEs in India, in addition to the dearth of studies examining the adoption of e-Marketing by small enterprises. A structured questionnaire with both open-ended and closed-ended questions in Vijayawada & Guntur Areas of the Andhra Pradesh State was chosen from a list of 1,200 SMEs that employ fewer than 50 people using a simple random sampling method. Findings revealed that the internet tools were showing positive effect on the market performance in the companies. The rest of the paper consists of implications, and scope for the future research
Investigation on Effect of Fiber and Orientation on the Properties of Bio-Fibre Reinforced Laminates
The objective of this work is to investigate the effect of fibre type and fibre orientation tensile and flexural shear properties of woven jute and bamboo fibre reinforced epoxy composites by experimentally. Laminates were fabricated by hand lay-up technique in a mould and cured under light pressure for 60 min followed by curing at room temperature for two days. Jute and bamboo laminates were made with a total of six piles by varying two orientation of fibre as to obtain four different samples. Specimen preparation and testing was carried out as per ASTM standards. The results shows the tensile strength and flexural strengths of the jute and bamboo laminates higher at 0/90? orientation and jute shows the highest in both tensile and bending strength
Proof-of-concept thermoelectric oxygen sensor exploiting oxygen mobility of GdBaCo2O5+{\delta}
In this paper, we demonstrate a proof-of-concept oxygen sensor based on the
thermoelectric principle using polycrystalline where
0.45<<0.55 (GDCO). The lattice oxygen in layered double perovskite
oxides is highly susceptible to the ambient oxygen partial pressure. The
as-synthesized GDCO sample processed in ambient conditions shows pure
orthorhombic ( space group) phase and a -value close to 0.5
as confirmed from X-ray diffraction reitveld refinement. The X-ray
photoelectron spectroscopy shows significant oxidation state in
non-octahedral sites in addition to and in octahedral
sites. The insulator-to-metal transition (MIT) is observed at nearly 340 K as
seen in electrical resistivity and seebeck coefficient measurements. The
seebeck coefficient shows a large change of about 10-13 V/K with time
constant of ~20 sec, at room temperature (300 K) when the gas ambience changes
from 100% oxygen to 100% nitrogen and vice versa, under a constant temperature
gradient of 1 K. The response in seebeck is found to be particularly large
below MIT. The diffusion of oxygen into the lattice leading to hole doping
shows a large change in carrier concentration resulting in a large change in
the seebeck coefficient in insulating state. On the other hand, due to
insignificant increase in already large carrier concentration in metallic state
the change in seebeck is minimal. Nevertheless, below MIT the response is
fairly reproducible within stoichiometry = 0.5 0.05. This
principle shall be of significant utility to design the oxygen sensors which
work at room temperature or even cryogenic temperatures
